Colonizing The World: Prehistoric Migration Issues


Author's Note: The scenarios inside are those of a time-frame from more or less thirteen,000 to 2 hundred,000 years before the prevailing, and as a consequence manner earlier than the era of agricultural settlements. We're handling our nomadic hunter-gatherer ancestors here. Key dates are: African starting place of present day humans, Homo sapiens, at approximately 2 hundred,000 years in the past; an Out-of-Africa migration started out kind of 70,000 years ago; our international colonization (besides for Antarctica and Oceania) changed into completed by means of 13,000 years ago.

When it comes to human beings, right here defined as Homo some thing or different, now not always simply Homo sapiens, colonizing the world from Ground Zero, it's Africa, properly several problems stand up.
Humans (as in Homo sapiens) originated in Africa and a few in the end did, slowly, ever so slowly, migrate Out-of-Africa (not that they genuinely were aware of this), in the end spreading out and colonizing the sector (other than Antarctica and Oceania east of Australia and west of South America) with the aid of at least 13,000 years ago. Exactly how isn't always completely understood, least of all by way of me. The vital, but not different, issue I even have is with appreciate to our ways and manner of trading in being solely nomadic land-lubbers for obtaining sophisticated maritime skills as properly; capabilities required if our global colonization state of affairs is to be believed.

Problem One: Boats Required but No Show-Boats Found


When it comes to human migrations, there are certain lands that have been colonized via each Homo sapiens and Homo erectus that worried crossing reasonably giant expanses of ocean - sizeable at least for the ones cultures that existed over 60,000 years in the past, whilst, as an example, Australia changed into colonized by using what is today called the Australian Aborigine. Even in advance, Homo erectus island-hopped the numerous Indonesian islands as attested to via fossil evidence. In each cases, those historical cultures needed to have received as an alternative giant boat-making, crusing and navigation skills that might allow a big enough population to pass over the sea waters, in view that even in the course of Ice Age conditions, these Indonesian islands, and Australia, were nonetheless remoted by oceans.
Sailing the oceans blue: it's a quite large ask for primitive people all those tens upon tens of hundreds of years ago. But, there's every other way of crossing the ocean blue - we do it all of the time today. We do not sail, we fly. Perhaps our historic ancestors had been flown to Australia and the Indonesian isles! Since aerial technology is even more outlandish than maritime technology, properly, perhaps the aerial technology belonged to superior beings - ancient extraterrestrial beings or historic astronauts. One other observation in favour - there are fossil finds of this or that hominid species at A, B & C. Alas, geographical points A, B, & C are separated by way of heaps upon lots of miles. No fossils are determined at any factors in-among A & B, or B & C. An apparent clarification, they didn't migrate among A & B and B & C at several tens of kilometres per generation; they had been flown from A to B to C, for this reason explaining the dearth of fossils in-among - however more about that rapidly.

Sooner or later for your nomadic hunter-gatherer wanderings you'll intersect the beach! Rivers and streams you can wade across or swim throughout, maybe use a buoyant log to keep on to if need be. Lakes can be walked around. But the sea!!! The oceans offshore should had been terrifying to our very historic ancestors, and rightly so. The ocean is nothing if not unpredictable and dangerous: from huge waves, gales, riptides, robust currents, razor-sharp rocks and shoals, sharks, jellyfish, hypothermia, and simply all types of unknowns lurking below the floor to add to your terrors. The tides have to have regarded to be a in basic terms supernatural manifestation, with out herbal explanation, an unexplainable motion of the gods somehow saying "this is our area, preserve away".
Would you instead be excessive and dry 10 miles inland or 10 miles out to sea looking to keep your head above water and no longer ending up as fish-food? It takes manner less effort sit on the seaside than to swim or sail in or on the ocean, and it is lots safer too!

Further, in maximum cases without a different land in sight, you haven't a clue what is on the other side of the sea, if some thing (maybe it is going on for all time and forever), or how far throughout it is to the alternative facet, and in any occasion you and your band of nomadic hunter-gatherers have more pressing wishes, like locating modern meals and this night's shelter. The coastlines and beaches offers an abundance of food stuffs and resources: shellfish, crabs, turtles, seals, seabirds, fish, even seaweed (dried for gasoline). Coastlines and beaches are precise.
Are you virtually going to prevent, make a raft and move crusing out into the pure unknown out of natural interest, although curiosity you possibly have? No, inside the each day hunt for survival you'll possibly ignore the ocean and just observe the coastline - which in the end will deliver you to maximum locations. If you come back to an impassable barrier, it's probable less complicated and a ways more secure to trek inland for awhile than divert sources to swimming or rafting around the barrier with all the dangers that could entail. In any occasion, it's now not all that east building and crusing and navigating a seaworthy boat or raft from scratch with none available-dandy how-to manual available. Further, you cannot drink the seawater so freshwater could should be carried on any hypothetical voyage. Do you have got leak-evidence packing containers? If so, how an awful lot do you need to take? Who knows?

There are 4 viable or realistic routes out of Africa. Even all through the Ice Ages while sea levels had been decrease, three contain an ocean crossing, which, I advocate our historical ancestors could keep away from. I suppose it's miles a ways less complicated, and more secure, to just follow the shoreline, so I choose the sole land route, up the west coast of the Red Sea and on up both into the Levant, or backpedal the east coast of the Red Sea and on into Arabia. You can comply with the African shoreline 'Out of Africa' and in the end attain China, but now not Australia, or Japan, or masses of S.E. Asian islands, the Channel Islands (off Southern California), Sri Lanka, and many others. Yet you discover historical human and human artefact remains in those locations, so our migrating nomadic ancestors glaringly did build boats or rafts and sail the sea blue and satisfy that curiosity, however the real why is unexplained - interest isn't purpose sufficient to put yourself in harms way. The fly in the ointment, in any event, and sadly and alack, there aren't any boats or rafts to be discovered, real remains or pictorial representations, inside the prehistoric archaeological document. Boats and rafts are all probably boats and rafts; boats and rafts are assumed but no longer demonstrated via any actual evidence. It's a sort of 'Catch-22'. Boats and rafts should be, but we cannot locate them!
It need to be stated that due to the Ice Ages, historical coastlines then are actually underwater and possibly applicable telltale archaeology (as in stays of boats) is therefore also underwater. Even so, the problem stays that I discover it hard to agree with our ancient ancestors would were brave enough to paste their toes within the oceans without a rattling properly purpose, yet, there had been places colonized through early man that even at the height of the Ice Ages there existed no land bridges for them to pass over, say to Australia, New Zealand, Oceania, Japan, lots of S.E. Asian islands, and presumably lots of different islands, massive and small. Conclusion: That's a huge anomaly that wishes a resolution.

Problem Two: Paradise Lost


Crossing the oceans blue is just the begin of anomalous migration troubles. If money, language obstacles, cultural differences, political structures, passports and visas, etc. Have been of no issue and you may tour to and live everywhere you needed, where wouldn't it be? Well, likely someplace no longer too hot, now not too bloodless, no longer too moist, nor too dry, an area where there are ample natural resources of food, fresh water, wooden, stone, and in all likelihood a few kind of ascetically attractive surroundings, and many others. With the exception of the scenery, all the ones other geographical and climatic factors would be even greater pressing for our historic ancestors without a access to supermarkets, hardware shops, air con, important heating and faucet water on call for. So the question arises, given a loss of populace strain manner back while, a loss of strain no longer riding migration faraway from paradise and toward hell, why did a number of our ancient ancestors undertake a nomadic way of life in what we would remember severe environments, like arid areas, the tundra, and many others.?
Unlike cutting-edge travelers, whilst our very far flung ancestors roamed the plains of Africa, their nomadic wanderings or migrations had been not geography directed. In an era wherein there has been no radio and TV, newspapers and magazines, GPS and the Internet, encyclopaedias and tour agents, there has been no information of what changed into over the hill, past the horizon. Food availability directed your travels and migrations. You exhausted one patch of turf - you moved on to the subsequent, and the subsequent, and the subsequent in a kind of random drunkards stroll. Logic dictates that even so you did not wander out of paradise or a cause facsimile thereof. But ultimately, like a drop of ink diffusing through a pitcher of water, the relaxation of the sector, paradise, hell and points in-between, were given invaded through our African out-of-towners - an invasive pest species that changed into to carry total demise and destruction of their wake, but it truly is some other tale. Anyway, why we colonized extraordinarily antagonistic environments when more exceptional alternatives had been available wishes a resolution.

Problem Three: Connect the Dots


There are  most important styles of clues that screen our possibly migration styles. Firstly, there are those archaeological web sites and from those skilled experts you'll be able to normally deduce what hominid species became gift and from various dating techniques, while. The problem is that such websites are all too few and some distance between. So, perhaps you have got an Australian Aboriginal web site across the Perth place (S.W. Coast) dated to say 30,000 years ago. Then say you have got some other website across the Sydney region (S.E. Coast) dated to 20,000 years in the past. So the belief is that a few Aborigines migrated from Perth to Sydney over the 10,000 yr c program languageperiod. But there is no web sites in-among, so that you do not certainly recognise in the event that they migrated in a immediately line between the two areas or was all of it only a total zigzag. Maybe neither if there's yet an undiscovered 0.33 website online, say in Darwin (mid-North Coast) from forty,000 years in the past, and a few Darwin Aborigines followed the west coast direction to Perth taking 10,000 years and some others the east coast trek to Sydney taking a span of 20,000 years. You can just about join the dots anyway you damn properly please if it gives proof to your pet theory.

The second line of proof is the usage of mitochondrial DNA found in contemporary people to attempt to paintings returned migration routes. For example, if mitochondrial DNA in cutting-edge Australian Aborigines has a closer mitochondrial DNA fit to fashionable Indonesians than to fashionable Fijians, then one would possibly conclude that the Aborigines migrated to Australia from Indonesia and now not from Fiji. I in my view don't like this kind of genetic proof. Firstly, DNA mutates over time. Evolution would be screwed if it didn't. Secondly, there is been an lousy lot of comings and goings considering these initial Out-of-Africa migrations started. Thirdly, there is been an lousy lot of breeding between the races in order that with the aid of now rarely all people is 'pure' whatever. Still, the specialists placed numerous religion in the checking out, so who am I to dispute their approaches and means?
So, how do you get from Point A to Point B tens of heaps of years in the past whilst Points A and B are separated by way of big ocean distances? Why do you cross from Point A to Point B while Point B is notably undesirable? How in fact will we virtually realize that Points A and B are the be-all-and-give up-all of begin and end?

Let's say Point A is lovely Hawaii, and Point B is the vast arid desert of outback Central Australia. How do you get from A to B? You can not stroll and comply with the shoreline. You cannot force or trip a horse. You ought to construct a boat and sail but it's a hell of a soar of courage you have got to grasp, and in any event you have not any concept what path to move in or that Australia even exists. And even if you did, why would you need to depart Hawaii (Site A) for the Australian Outback; and if you did reach the Outback (Site B) why wouldn't you turn proper around and head again to Hawaii once more?
Well, you can be flown non-stop from Hawaii to Central Australia. We crossed over ocean obstacles due to the fact we have been airlifted over them. You can be flown to Central Australia and stranded there. For the equal purpose, we didn't voluntarily adopt the tundra as domestic - it changed into forced on us as an adapt do-or-die experiment. Flight might also explain the shortage of relevant archaeological web sites among A and B. If our ancient ancestors nomadically walked thousands of miles between Point A and Point B, you'd anticipate archaeological evidence to be determined along the assumed join-the-dots direction. But in case you fly, or are flown, then of route you wouldn't locate any in-between sites containing any relevant archaeological proof.

Resolutions


Right about now each physical anthropologist analyzing this is sticking very lengthy and very sharp pins in J.P. Voodoo dolls and calling me all sorts of unprintable names. Of route our historical ancestors did not have the era at hand to fly, so of path no flying machines have been discovered within the prehistoric archaeological document either. My obvious proposal right here is that historic astronauts, the 'gods' of vintage (and there is a few evidence that even 30,000-50,000 years in the past our historical ancestors had grasped the concept of the supernatural and of supernatural entities), genetically engineered all the diverse Homo something or other from earlier hominids which in turn were artificially decided on and bred from African primates, like the chimpanzee. We collectively, Homo some thing or different, were genetically engineered and given all those anomalous developments related to Homo some thing or different, like a splendid-high IQ, bipedal gait, racial facial and character facial forte.

From their crucial African laboratory, Homo something or different become then dispersed over thousands of years as specific and person experiments in colonization. We were transported right here and there, left to our own devices to live to tell the tale or not - sink or swim. In most instances it became sink and extinction. But, from time to time, it became survival - we floated and we swam. Ultimately almost all of the Homo something or other went kaput, however Homo sapiens executed a tremendous result. We have been that robust species (us - modern human beings) the end made of all of the engineering and colonization experimentation. At that level, we had been given or taught the items of civilization, especially agriculture more or less 10,000 years in the past then left petty plenty on my own and to our very own devices, with only at-a-distance surveillance - modern UFOs - although a few experimentation continues - alien abductions.

There are, IMHO, a couple of other anomalies supporting this wacky idea.


One different anomaly, if we are so crash-warm accurate to colonise the world (apart from Antarctica and Oceania) and move some ocean barriers to get to some components, consequently finishing the job within the Americas by 13,000 years in the past, perhaps even manner earlier, why didn't we colonize the Pacific Islands, Oceania east of Australia and west of South America, until clearly quite currently - beginning just a few roughly 4000 years before the present, finishing off with New Zealand (except for Antarctica), closing cab off the rank way after the begin of the Common Era, or A.D. To a few. Australia changed into first populated 50,000 to 60,000 years ago, and New Zealand is simply throughout the street and over the hill, as a minimum in comparison to the space lower back to our African point of beginning. Depending on supply, it took however 10,000 to twenty,000 years to get from Africa to Australia, but some 70,000 years to get from Africa to New Zealand. Something's screwy someplace, but that boosts the concept that ocean voyages are a highly current potential of ours, and therefore, manner lower back when, we did not sail across the oceans blue to Australia, Japan, Sri Lanka, and so on. However have been taken there.

Southern California Dry Lakes Racing History


Southern California...I've heard it defined as "extended wasteland parking to the beach". But it wasn't constantly like this. Some 18,000 years ago, components of So Cal had HUGE inland lakes. Everything changes given enough time and nowadays those lakes are long empty. They at the moment are Southern California's dry lake beds. So why write approximately geology in a piece of writing about cars? I'm just putting the again drop for one of the maximum exciting periods inside the development of Hot Rodding. Read on my buddies and find out some cool car history!

Southern California's dry lake beds, locations like Muroc, Harper, Rosamond, and El Mirage have attracted vehicle racers considering the beginning of the 1900's. Shortly after a few man made more than one changes to his vehicle, he commenced searching out a very good region to test them out and not be disturbed inside the technique. These dry lake beds healthy the invoice to a "T", pardon the pun!

By the 1930s, mounted dry lakes racing started to evolve in response to several elements. Young men with mechanical capacity and a love for tinkering with their ample and reasonably-priced project automobiles were meeting every different, organizing into golf equipment, and racing to peer what the repay turned into for all their efforts. Racers from the L.A. And Orange County vicinity started to "centralize", running their automobiles at the Muroc dry lake. Because of its size, Muroc became the earliest famous spot. It ultimately got taken over while Edwards Air Force Base was constructed. Racing persevered to develop, no matter dropping Muroc. Other popular web sites sprang up (Harper, Rosamond, and later El Mirage) to fill the space for an area to run motors.

Accidents and accidents had been an unfortunate (and unwelcome) spinoff of this young interest. The Southern California Timing Association, began in 1937, become the result of numerous clubs cooperating within the hobby of company, safety and maintaining the nearby government off racers backs. In those days, maximum of the motors running on the lakes have been street motors. Once there, off got here whatever that didn't make a automobile "gow". Some racers went to extremes, extensively Dick Kraft, who pulled off the body and sat on a board over the rearend even as racing in a washing healthy!

Modifications, like swapping carbs or walking alcohol became commonplace. The Ford Model A and B four-cylinders had been the engines of choice. Two or four port overhead conversions were done on them. The SCTA Racing News recognized cars by their heads (Winfield, Riley, Cragar, and others). At first, 4-bangers held their personal in opposition to the more moderen V-eight Flatheads, basically due to the amount of pace device that existed for them. However, history suggests that shear length gained out in the end and 4's gave manner to 8's fast.

Side via facet drag racing wasn't the preliminary gadget used either. At first, automobiles ran singly to qualify for classes based totally on velocity. Then all the automobiles from every magnificence could line up for one remaining race with anybody walking right away to decide "king of the hill". Eventually, a four-car limit became imposed. The SCTA commenced to broaden extra particular instructions. Before World War II, cars raced in Roadster, Modified, or Streamliner instructions. It changed into quite primitive and differences had been no longer constantly tough and fast. Later, classes have been more standardized, that specialize in factors like engine length and changes.

This quick golden age of racing turned into marked by using limitless experimenting and domestic brewed fabrication. Ed Iskenderian became as soon as quoted as announcing "It was just amusing. Everyone had their personal ideas, and you'd research from the alternative guys - what they had executed. That's the way you found out what you would possibly need to put together."

Moving an SME Into a Virtual Desktop




What is a digital laptop?

Virtual Desktop generation has been round for a while, however has largely refrained from the reach of small corporations due to the bandwidth requirements... Till now. Large net connections have turn out to be low cost and more quite simply available because of improved competition, which has introduced Virtual Desktop mainstream. But what's the elusive Virtual Desktop everybody talks approximately? In layman's terms, the computer a consumer experiences on their pc or laptop is hosted centrally on a server, including all of the programs, information and personal settings. The laptop or laptop effectively becomes a thin patron, serving no different motive than to provide get right of entry to to the Virtual Desktop.

The blessings include:

* centralised control, which means that most issues may be resolved from the server
* the processing movements from the pc or laptop to this negating the want to upgrade neighborhood hardware to meet the today's OS and minimal hardware necessities
* access to this will be restricted to a tool and/ or region and no statistics is stored domestically
* it is able to be accessed from everywhere and on any device along with cell telephones and drugs allowing for bendy working and far flung get entry to

Providers offer the service on a fee per user per month foundation, whereby typically the user matter can be extended right away and reduced with 30 days' word. The flexibility of Virtual Desktop is very appealing, mainly to small companies, because you simplest pay for what you operate. The charges are based totally on the variety of customers (and the related economies of scale) and the software program and garage requirements.

What takes place to current software program and hardware whilst you migrate to Virtual Desktop?

You use your current workstations and laptops to access the Virtual Desktop, but you now not require any other software apart from the running gadget, as all your software is provisioned and authorized with the aid of your Virtual Desktop issuer. The computer systems can therefore be stripped right again to the working machine to provide them a brand new rent of existence and also you may not need to improve them for some time due to the fact all the paintings is completed inside the Virtual Desktop. Local servers may be decommissioned, or redeployed in other roles.

What are the considerations for Virtual Desktop migration?

As the Virtual Desktop is hosted externally, it requires an good enough and reliable internet connection to offer the most beneficial person revel in. Businesses will even must spend money on a secondary or failover net connection for resilience. On the whole, processor extensive applications e.G. Media and design related packages like Photoshop and AutoCAD can not virtualised, in which case corporations may need to don't forget a hybrid approach. Finding a provider that suits your precise business wishes can be complex and therefore it's far critical to conduct adequate due diligence to choose a resilient and reliable answer.

Among the key issues are:
* uptime (and downtime)
* security
* resilience and disaster healing
* connectivity
* infrastructure and compatibility
* scalability
* support

A exact provider will deliver a relaxed and seamless consumer experience, permitting your employees to work uninhibited and leave you secure inside the know-how that your information is relaxed.

What about my records?

All of your facts which include e-mails, files and databases stays your property always. The Virtual Desktop company ought to not withhold bodily access to the information (assuming there aren't any excellent payments). This is generally finished by way of copying data to an encrypted USB tough drive within the records centre. Even although your facts is sponsored up in the cloud, it is good exercise to implement a supplementary backup strategy to lower back up your data to any other place.

Is it easy to trade vendors?

Switching vendors is a relatively seamless process, nearly like converting current debts. Your surroundings is configured and examined at any other provider, your records is transferred and your users log into the brand new platform and keep to paintings as normal.

What are the dangers?

You need to make certain your local infrastructure can provide dependable get right of entry to to the Virtual Desktop. Network and connectivity troubles will hinder your potential to paintings and the downtime will reason monstrous frustration on your employees. A resilient internet connection is imperative.

You want to ensure you associate with a good and reliable partner, capable of turning in a Virtual Desktop provider this is right in your enterprise. Apart from making sure the obvious namely; that it works, they want to be attentive and responsive, as it is simple to drown within the bureaucratic pink tape of trade request and SLAs, with the intention to make you rue the day you migrated to the cloud.

How to Get Maximum ROI From Cloud Deployment




Enterprises continuously attempt to increase their overall performance and reduce running costs at the same time as retaining a high great of carrier. Many businesses have migrated to the cloud within the beyond few years due to growing advocacy for this generation through commercial enterprise users.

Cloud ROI is hard to understand and measure for even the most experienced commercial enterprise managers. Below are a few tips to useful resource you in maximizing the ROI of your cloud deployment.

    Maximize Use of Cloud Resources

Enterprises ought to use historical records to are expecting future use of cloud sources and purchase sources as a consequence. If sources are being optimally utilized, there may be no unused capacity that wishes to be reallocated to a specific task. Cloud deployment permits bendy scaling. Therefore, should the need get up increasing capability isn't always a trouble. Utilizing cloud sources to the fullest is the important thing to growing ROI.

    Minimize Security Risks

Many enterprises are exposed to security risks like statistics theft and lack of treasured records. To maximize ROI, it's far necessary to appoint ok security measures. Most cloud carrier carriers already include this option into their services, but organisations ought to make sure that there are not any security dangers because of inaccurate configuration or misguided use of a resource.

    Deploy Cloud Applications with a Wide Footprint

To maximize the ROI of cloud deployments, corporations must install applications that have a extensive footprint. The footprint of an application way the quantity of methods it will automate or take over completely. For instance, if an business enterprise uses a cloud application to act as an upload-on to its HR branch, it'll still require a full-size personnel to run day-to-day operations in that department. However, a similar application having a huge footprint will automate a multitude of responsibilities. This method that workforce may be redeployed and applied to fulfil other desires of the branch. This will increase efficiency and save capital, which in turn maximizes ROI.

    Minimize Hidden Costs

When an employer purchases services from a cloud provider issuer, there are numerous limitations on the usage of packages and APIs which might be being furnished. These barriers may not appear to be a threat when the machine is being deployed, however as the operation grows, those might prove very costly for the customers. Business managers should attempt to negotiate to get maximum use of packages and APIs in the settlement even though it is not required at the contemporary time. The excessive scalability of the cloud model is not very beneficial if there are strict limitations on use of sources.

    Convert CAPEX to OPEX:

Business managers must try to convert the maximum quantity of CAPEX (capital expenditure) to OPEX (operational expenditure). This is executed routinely to a point due to the fact the cost of buying servers, workstations and licences is eliminated. However, managers can maximize this conversion through signing a win-win address the provider provider to offer different value introduced offerings like full scale IT support and maintenance contracts. This can also help in launching new services at a totally affordable value.

    Accurate ROI Analysis:

Cloud is a much-mentioned phenomenon in commercial enterprise circles and among IT managers. However, there are definitely only a few human beings that fully apprehend it. Executives should attempt their quality to take a look at each and every issue of Cloud before acting ROI analysis for an agency or a task. An accurate calculation of ROI can assist companies take the rights steps for maximizing ROI.

    Ensuring Easy Cloud Adaptability

Cloud computing has many tangible and intangible benefits that may be reaped with the aid of nicely-deliberate organisation deployment. An crucial factor to ensure successful deployment is selling the use of cloud among all employees so that they benefit self assurance and quickly adapt to this new generation. This will assist control do away with legacy structures as soon as viable with out a whole lot resistance from personnel. There is a direct correlation to an boom in cloud ROI and its good sized use in an business enterprise.

The myths and truths of the Cloud, in 5 keys

The existence of the word Cloud has been circulating in the network for quite some time now. Even so, many of these times it is used without understanding it in its fullness. What benefits can it bring to IT professionals? What is understood as Cloud Computing?

Cloud Computing, what is it?

Cloud computing has become a standard for most IT organizations, but the idea is not fully understood. The term "CLOUD" seems to mean almost anything, that depending on the context and who mentioned it, generates different responses that cause confusion in all areas.
The language created around the cloud does not help. In the Information Technology sector, acronyms love them and the cloud does not disappoint in this aspect. From SaaS, through PaaS, to IaaS and beyond. With the memory of the old days and how simple it was to refer to Cloud Computing as something public, now we are mixing different models of hybrid, private implementation and in multiple clouds that distort the message. In addition, with so much information, and so much exaggeration, it is difficult to distinguish the fictitious from the true.
Because we like to be clear, we are going to test up to five common assumptions about cloud computing.
Are these claims about a true multi-cloud environment or myths?
  1. Your cloud vendor always manages the services you use in the cloud: MYTH . 
    Cloud does not necessarily need to be completely managed by another. IT teams can enjoy considerably high control over their cloud resources based on their level of sophistication, technologies and management capabilities and business drivers, especially if they are using services based on IaaS and PaaS.
  2. The cloud creates a culture of "use and throw": TRUTH . 
    This is a significant difference between the standard IT infrastructure and a multi-cloud environment. Previously, companies invested in hardware and software assets, and then did everything possible to make the most of them and maximize the return on investment. The cloud changes that. In a multi-cloud environment, it may be appropriate to destroy current resources, fix deployment configurations, and then generate a new instance. It depends on how an application is designed and the type of cloud resources used when you need to change an application or solve a problem in an application running in the cloud .
  3. The cloud is highly dynamic: TRUTH . 
    In a certain sense, this is very good; The dynamic nature of cloud resources is a major reason why they have become so popular. Most current multi-cloud environments are at least as dynamic (if not more so) than traditional IT due to the inherent automation and configuration of cloud services. This makes them flexible, scalable, agile, all those good things, but it also results in greater complexity when managing changes in applications.
  4. The proliferation of new services is much faster than ever thanks to the cloud: TRUTH . 
    The pace of change is an important differentiator between solutions and services in the cloud and traditional IT. The cadence in which the main cloud providers launch new services is faster than anything we have seen before. The advantage for cloud users is that updates are often automatic and services are available for immediate use. At the same time, however, frequent updates and updates require a close eye to configure and manage effectively.
  5. The management processes are so individual and automated that the best service management practices no longer apply: MYTH . 
    Although the administration of services plays an even more important role in the management of its multi-cloud environment, since the documentation of changes, problems and incidents is still necessary and will require more automation. Following configuration management best practices and having an automatically populated configuration management database through multi-cloud discovery provides the only point of reference for service management processes to relate to cloud resources .
    The complexity of the cloud can feel like something good and cursed at the same time. While it has opened countless doors for IT to add more and better value to the business, cloud computing also requires a unique and often innovative approach to manage and optimize.

HOW TO CALCULATE THE ROI OF YOUR CLOUD INFRASTRUCTURE


 When a client invests in technology, the first question asked is: What will be my return on the investment? Whether in social networks or in the cloud, knowing how to calculate the ROI is essential to convince the company's director and give continuity to the project, and even to revalue some points of the strategy.   The fact is that calculating the ROI in Cloud services is a challenge. The benefits, some intangibles, can not simply be translated into numbers. Especially for companies that already have part of their virtualized environments and that already optimize resources at another level.   However, at the time of making the accounts, the first sum that comes in favor of Cloud Computing, is all its ability to offer the user access at any time, from any place and device that have an Internet connection. The second is the reduction in maintenance costs with the investment of new hardware and specialized equipment, as well as the continuous updates of their software.   The reduction of costs is just one of the benefits of the Cloud, which can be accounted for in the ROI. Probably, the greatest potential for return is that the cloud provides the company with possibilities that did not exist before. Mobility is one of them. The connection between several collaborators sharing data and files in real time is another.   The increase in productivity is something that has to be added to that account, since the ease of access to work information depends only on an Internet signal. Technically, the implementation of apps in the cloud is much easier and faster, decreasing the overall costs of development.   Another important point is the security of information: the most strategic data can be shielded in a Private Cloud, with limited access to certain collaborators. The most common, can be in a public cloud, with access to several users.   An extremely positive point of the Cloud is its network and storage capacity. Companies that migrate for Cloud Computing solutions have an extraordinary gain in these issues, paying little for them.   As with any major technological change, transferring data to the cloud requires a different formula to calculate the return on investment. For companies with a focus on short-term costs and traditional metrics, the implementation of applications in the Cloud may or may not be added to the planning. But for organizations that value business agility, development productivity, customer retention and market leadership, this technology becomes much more attractive.   In fact, the Cloud ROI calculation varies according to the business methodologies of each company and the problems that were solved by Cloud Computing.   Find a specialist who can help you make that calculation, thinking about the before and after the hiring of Cloud. Evaluate the agility that the company has when responding to customer demands, both at the beginning of the implementation and afterwards. Consider also the improvement of the total cost of ownership, which helps users plan production in a way that is more suitable for the business. Finally, evaluate the capacity that the company has to prevent the impact of the changes according to the rhythm of the market.

Depicting a Herd of Woolly Mammoths Using Prehistoric Animal Models


Using Mammoth Models to Make a Realistic Herd


Dinosaur model fanatics and version creditors are capable of create a number of exciting scenes the usage of numerous distinctive scale models of dinosaurs. The scale sizes of the fashions can vary drastically and from our perspective, the wider variety of scale models available offers a version maker extra freedom in phrases of the scenes they can create. Interestingly, with regards to Ice Age mammals together with Woolly Mammoths, there are some of desirable high-quality models around, but most of the people of these tend to be the same scale - 1:20. Creating a sensible-looking scene the use of Woolly Mammoth models takes giant care and judgement. However, a number of mainstream model makers now provide Woolly Mammoth models as a part of a much broader prehistoric animal and dinosaur version series. Companies such as Schleich and Papo have additionally made models of baby and juvenile Mammoths. These museum first-rate models all in about 1:20 scale offers scene designers the danger to depict their very personal Woolly Mammoth circle of relatives.

Woolly Mammoths - Extinct Elephants

Woolly Mammoths are contributors of the elephant family (Elephantidae), they lived in herds just like their extant cousins the African and Indian elephants of today. Palaeontologists consider that the herd shape of Woolly Mammoths which include Mammuthus primigenius, became the same as that visible in dwelling species of elephants. A matriarch might manage the herd which would be constituted of her daughters, sisters and their younger. Bulls very in all likelihood lived a solitary lifestyles whilst absolutely mature. Young males would be pushed from the herd by using the matriarch when they reached maturity and breeding age. These younger males might probable live in small agencies made from other adult males of similar age (bachelor herds). Bulls would compete for the right to mate with the women and the herds would likely have moved superb distances each season in search of fresh grazing.

Create Your Own Prehistoric Scene

Recreating a prehistoric scene featuring a herd of Woolly Mammoths is pretty complex. The herd might be produced from a number of individuals and there might be huge size and age difference among herd members. The animals might variety in size from calves that has been born that year to the older women who would possibly properly be sisters of the dominant matriarch. The matriarch herself might be greater than fifty years of age. Mixing different Woolly Mammoth fashions from exceptional manufacturers, instead of spoiling the effect might simply enhance it. As there would be range within the herd, version creditors need to experience assured to mix Papo models with Schleich fashions as an example. Both those firms produce hand-painted, anatomically accurate fashions of these prehistoric elephants so model collectors can blend those  units of Mammoth fashions as much as create the effect of a diverse variety of individuals living in a herd.

Choosing the Models According to Size

It is not simply the dimensions of the fashions that the scene designer has to get proper, but the coats of these animals might all differ. The Papo grownup Woolly Mammoth model has a darker shading than the Schleich Mammoth replica, these two portions together might appearance first-class in any diorarma being built. Scientists studying the frozen hairs preserved on the remains of Siberian Mammoths which might be found thawing out of the permafrost inside the most northerly components of Russia, realize that there has been vast variant in vast coat colour.

The coat consisted of two awesome layers. A "shaggy" topcoat with an undercoat of denser hair for insulation. The coat can be coloured various sunglasses of brown or reddish, possibly bordering on ginger, to almost jet black. Albino Mammoths had been possible but those animals would had been not likely to survive inside the wild. No version maker has produced a white Mammoth but but the coloration variant between producers together with Papo, Schleich and Collecta is greater than ok for any typical prehistoric animal model scene.

Scale Replicas

There are some of correct 1:20 scale or thereabouts replicas to be had. Papo, Schleich and a number of other mainstream version and determine makers now have prehistoric Mammoths of their model stages. Creating a herd of Woolly Mammoths has been made simpler with the advent of the juvenile and toddler Woolly Mammoths from the French manufacturer Papo earlier this year. When choosing a Woolly Mammoth reproduction it's miles helpful to remember the fact that not like present day elephants they'd pretty brief tails and small ears - each adaptations for a cold climate. Look out for those features on any substantial model you is probably interested by purchasing.

Getting the Tusks Right

The tusks of these animals grew for as long as the animal lived. Both women and men had giant tusks, similar to us human beings with our left or right hand bias, palaeontologists accept as true with that Woolly Mammoths had a desire for using both their right or left tusk. Differences in the wear sample seen on pairs of significant tusks recovered from person specimens provides proof to the scientists as to whether or not this particular animal became right-tusked or left-tusked. Tusk size might consequently have various at some point of the herd, it would have been dependent on the age of the person animal. A number of Woolly Mammoth species and sub-species had been defined, at least eight from the Americas by myself. The tusks of Mammoths tended to curl outwards however there was sizable variant. The form and length of the top incisors (tusks) is simply another difficulty for the model maker to situation themselves with. The Papo huge Mammoth model has a particularly nice set of tusks and the model itself measures greater than twenty-5 centimetres lengthy. This massive model can play the role of any bull in the prehistoric scene, must one be required.

Displaying your Models

The fashions may be presented in opposition to a painted backdrop or picture. None of the mainstream manufacturers present their fashions of prehistoric elephants in presentation containers but model creditors can easily conquer this slight problem. Mammoths have been creatures of the open plains, even though a number of species are associated with extra closed forested environments so the dressmaker has huge desire as to what heritage to use. A scene depicting early spring or overdue autumn, instances in the year when Mammoth herds might have come together to form top notch-herds as those elephants made their annual migration to the quality feeding grounds, is probably appropriate. Posing the animals on artificial grass or the use of grass within the foreground is satisfactory. The models get up properly on this medium and animals which include W. Primigenius fed on grasses and small sedges (finely serrated enamel with dense plates, indicate a grazing food plan as does stomach content material evaluation of frozen mammoths).

Although Woolly Mammoths had been depicted in cave art, no residing character has seen a big herd. In truth, nobody has visible the Woolly Mammoth for hundreds of years, so version makers and architects can use their imaginations based totally round some clinical ideas to guide them as to what sort of scene they would really like to create.

Key Cloud Migration Considerations


The business case has been made and you have appointed your venture sources for cloud migration. It's now time to scope and plan your migration. Moving your Enterprise IT workloads to the general public cloud is a huge decision and immediately alters the way you use your commercial enterprise. It has to be approached strategically and should not to be taken lightly. There are many advantages to cloud IT, but you should carefully planned and plan. The wrong decision is going to fee you in more approaches than you care to calculate.

Many mind ought to have cluttered your mind along with, which of the cloud carrier companies exceptional meets your wishes? How could you calculate the value of cloud migration and operation? How are you able to make certain provider continuity throughout and after the circulate? What kind of security measures need to you take and what do you need to prepare for? How are you able to confirm regulatory compliance? There are many more questions that you need to answer prior to migrating to the cloud.

In this article, we can talk few of the maximum urgent troubles to consider when planning the pass.

Private, public or hybrid?

One of the primary matters to decide while migrating to cloud is whether or not you will move personal, public or hybrid.

On a private cloud, you will have a dedicated infrastructure for your enterprise, controlled both with the aid of your groups or 1/3-birthday celebration companies. Your organisation may have its personal dedicated hardware, walking to your private community, and positioned on or off premises.

A public cloud affords its services over a community that is not your personal one and it is available for others to use. Usually it is off-website and offers a pay-in step with-utilization billing version that would bring about a cheaper answer, as soon as it correctly shares sources over the diverse customers.

Hybrid cloud combines your private or traditional facts generation (IT) with a public cloud. Usually it is used to scale up and down your infrastructure systems to meet demand wishes for seasonal groups, spikes or economic closings, or to address the application other than the statistics storage, consisting of setting up the utility layer in a public environment (for instance a software as a provider) at the same time as storing sensitive records in a private one.

Current infrastructure usage

This is virtually one of the things you need to assess while thinking about a pass to cloud. In traditional IT, companies generally buy their hardware based on usage spikes so that you can avoid issues whilst those eventualities arise. By doing that, businesses may also grow to be with underutilized equipment, which could bring about a large waste of money. Taking a take a look at your overall performance and capacity reports can help you deal with those workloads on cloud and decide whether to launch unused capability for other workloads or really pass them over and avoid new investments.

Cloud Workload Analysis

Out of your IT workloads running for your datacenter, a few might not be suitable for migrating to the cloud. It isn't always smooth to generalize the criteria for selecting the proper packages for migration, but you need to bear in mind all aspects of the execution surroundings. Given the service parameters promised with the aid of the provider, are you able to obtain the identical degree of ability, overall performance, usage, safety, and availability? Can you do higher? Can you have the funds for less?

Your destiny increase must be factored into the choice. Can the cloud infrastructure scale as your useful resource consumption grows? Will your software be compliant with regulatory rules whilst hosted inside the public cloud? How does the cloud infrastructure cope with compliance, if at all?

In order to make the proper decision, you ought to very well understand your modern workloads and determine how carefully their necessities, both for present and destiny evolution, can be happy.

Application Migration strategies

There are multiple ranges of adjustments you can want to do in your utility relying in your brief term and long time commercial enterprise/technical dreams.

Virtualization - This model helps a brief and smooth migration to cloud as no changes might be required to the application. Ideal candidate for legacy applications.

Application Migration - In this example your software will go through minimum architecture and layout modifications so that you can make it most reliable for a cloud model of deployment. For instance, you could choose to apply a No SQL database available on cloud.

Application Refactoring - This model would require a first-rate overhaul of your application proper from the architecture. This is typically performed when you want to leverage the state-of-the-art era stack.

Backup policies and disaster recovery

How are your backup regulations running these days? Do they healthy along with your cloud provider? This is also an crucial point that corporations ought to cautiously do not forget. Cloud carriers can have wellknown backup policies with a few stage of customization. It is really worth it to have a take a look at those and spot if they may be appropriate to your company before they become a ability roadblock. You'll want to take note of retention frequency, backup kind (which include full, incremental and so forth) and versioning.

Disaster recuperation and commercial enterprise continuity are important even for the smallest businesses. Recovery time goal (RTO) and healing factor objective (RPO) are essential values that outline how a great deal facts you're inclined to lose and what quantity of time you are willing to permit for the statistics to be restored.

Licensing

Is the utility licensed in keeping with VM, consistent with core, or for general infrastructure footprint? This can have big value implications. If the licensing version calls for that each one to be had resources be taken into consideration despite the fact that no longer allotted to the client, licensing prices will increase if migrated to a public-cloud platform. Similarly, if the software licensing is primarily based in line with middle and the cloud company does now not offer the ability to configure your cloud surroundings consistent with center, this may have an unfavourable effect to your licensing cost.

Integration

Organizations frequently discover application dependencies too late within the method of migrating workloads, resulting in unplanned outages and limited functionality to systems even as those dependencies are addressed. Understanding the relationships among programs is essential to planning the series and manner wherein cloud migrations occur. Can the application exist at the cloud in isolation whilst other systems are migrated?

Compatible operational gadget

Clouds are all approximately standards, and also you need to keep versions of your operating systems and middleware up to date while you aim to migrate them to a cloud issuer. You want to think about that cloud provider vendors (CSPs) do not support give up-of-lifestyles working structures or the ones which are being phased out. The equal likely applies in your middleware and databases.

Hopefully this publish will assist you make selections about your cloud migration.

How to Perform an Exchange Migration


In this phase, existing mail accounts and messages are migrated from the existing messaging environment to the Microsoft Exchange 2003 environment. Your migration strategy must be executed in a manner that is transparent and that has the minimum possible impact on your current e-mail users.

To accomplish these goals, an effective migration strategy and appropriate migration tools must be designed and implemented. They must address all aspects of system migration, including networking, external interfaces, account synchronization, management systems, and parallel operations.

This chapter contains the following sections:

Developing a Migration Strategy

Preparing the Migration Plan

Using Migration Utilities

Tips for a Successful Migration

Refer to the Microsoft Exchange 2003 Migration Guide for complete information on migration.

Developing a Migration Strategy
The typical site where Microsoft Exchange 2003 is installed has an existing mail system that provides messaging services to its users. Migration is the act of moving or copying the data for all users from the legacy (existing) system to the Microsoft Exchange 2003 system. Migration is performed so that all customers can be serviced by the Microsoft Exchange 2003 system, not simply those new subscribers following the installation of Microsoft Exchange 2003.

Migration is the most complex facet of any deployment project. Even though this document provides a framework to follow for migration, no two migrations are exactly alike, due to the differences in each site's legacy mail system and its integrated systems and procedures. A successful migration depends upon accurately identifying all unique aspects of the system that are to be duplicated in Microsoft Exchange and then duplicating these conditions through development and testing prior to the actual physical migration.

The principal issues of concern in any migration to a new mail service are data integrity and transparent cutover to production. Data integrity guarantees that all mail accounts, stored messages, and associated personal information and preferences (for example, address books, passwords, and so forth) are accurately retained in the new mail system. Transparent cutover to production means that the transition is handled quickly, cleanly, and with no disruption to the end-user experience.

In typical migrations, the total amount of time required for a successful transition is a function of system complexity. Both the total number of mail accounts and the total number of stored messages are significant factors. In addition, migration time can be affected by system and site-specific issues.

Any migration strategy must address:

Migrating accounts

Migrating mailboxes

Migrating Accounts
This migration involves all of the information that uniquely identifies and describes a user, including class-of-service data that defines the service for which users are subscribed. Account data must be placed in the Microsoft Exchange 2003 system before message data. The first task is therefore to collect and transfer account data from the legacy system and then transfer it to the Microsoft Exchange 2003 system.

If your legacy system has domains and organizational units, you must prepare to migrate these also.

Migrating Mailboxes
This migration involves message data--the actual messages to be migrated that belong to the user. The mailbox is simply a collection of the messages belonging to a particular account.

Preparing the Migration Plan
Migration involves significant planning, more so than any other deployment task. This planning is necessary because the activity is exposed to existing users and will, in most cases, be the initial experience that users have of the new system. It is very important to plan for every eventuality in order to avoid problems during the migration.

Refer to Appendix A for information on how to obtain a sample migration plan.

Migration is 95 percent planning and 5 percent execution. A multitude of factors that must be considered in order for a migration to succeed.

The Migration Plan provides a detailed, step-by-step procedure for migrating accounts and mailboxes to Microsoft Exchange 2003. The deployment team should make several dry runs of this plan, with each dry run resulting in a subsequent refinement of the plan.

Any migration plan should address these considerations:

Ensuring systems readiness

Coordinating with other groups and identifying dependencies

Verifying software installation and configuration

Setting up the test system

Providing provisioning connectivity

Testing the migration

Choosing full or limited migration

Resuming service

Ensuring Systems Readiness
All systems to be tested must be ready and operational before testing begins. In addition networks must be implemented as defined in the architecture design (see Chapter 2).

For each original e-mail system, separate IP settings (each with unique "A" records in the DNS) must be established for the following:

Host Address This is the permanent IP assignment for the host.
Service Address This is the address that is used by all e-mail clients for a service. The Service Address will be re-assigned to Microsoft Exchange at the time of account migration.
Service Proxy Address There must be a Service Proxy Address for each Service Address. The IP number used for any Service Proxy Address will match its respective Service Address. The Service Proxy Address will be used for proxy targeting where proxy is used on the Microsoft Exchange system. These can be de-assigned after all migrations are complete and when it is determined that a revert procedure is not required.

Coordinating with Other Groups and Identifying Dependencies
Since any migration touches upon many aspects of a company's operations, make sure you coordinate the migration with all affected groups and identify dependencies--that is, determining the order in which systems should be migrated.

Verifying Software Installation and Configuration
In addition to installing Microsoft Exchange 2003 (see Chapter 3) and verifying that all components inter-operate, you must set correct Microsoft Exchange environment settings for the root user. These include the correct $PATH, $LD_LIBARARY_PATH, and $Microsoft Exchange settings in order to access the Microsoft Exchange migration tools.

Setting Up the Test System
To validate a migration plan, the test system should have the capacity of production systems, including the proper storage volume configuration and failover configuration (service continuity). The test system must have Internet connectivity, as Proxy mode operations cannot be tested without this.

Aside from equipment that mimics the production system, test driver machines must also be available to power the migration and capacity tests. The test drivers must be configured with migration utilities as well as with mail clients or other test utilities for accessing and sending mail.

At least one test host is required for migration testing; this host acts as a surrogate for the actual online e-mail hosts and holds all mailbox data required for testing.

Providing Provisioning Connectivity
The provisioning interface must be validated before migration can occur. C API procedures should be tested to ensure that modifications performed on the ISD are successful and are propagated to the provisioning database. The Perl API set for batch account migration also must be tested. Last, administrative routines in the provisioning system or ISD must be validated.

This testing is performed in a dual provisioning environment. The purpose of dual provisioning is to ensure the ability to revert to the legacy mail system in the event that the new mail system in not successful.

For provisioning, automatic mailbox creation must be tested. Zero-length mailboxes are typically not migrated; rather, they are turned on in Microsoft Exchange 2003. The first time mail is received or checked, the mailbox can be created. A large test database (representing the volume of anticipated accounts) must be test-migrated to ensure that the procedure works and that the destination ISD database can handle it.

If possible, you should identify a group of "friendly" users willing to assist in identifying any problems or errors

Testing the Migration
Before the migration can occur, comprehensive testing on the production system must be completed. Migration test activities are "non-intrusive" to the existing mail system and are conducted from a separate system using actual user account information and a test copy of the production user data.

The procedures for extracting account data from the legacy system must be tested. The method and utilities to load these accounts into the ISD must be validated through testing. Each class of service must be included, as well as each combination of account attributes, such as forwarding, aliases, and vacation replies.

In addition, the process of moving mailboxes to the Microsoft Exchange 2003 system must be tested. This process includes the method of suspending the account, the physical transfer of messages and attachments, and the return of the account to active status.

You should make any possible configuration changes to prevent network or system loading. In addition, you must establish any special network, host, or storage accommodations that may be required for testing. A special network configuration may be required to prevent traffic complications introduced by migration testing. Another solution may involve localization of the original mailbox storage to the Microsoft Exchange 2003 system.

--------------------------------------------------------------------------------

Note: Depending on the particulars of a given migration, you may need to create new scripts or modify existing migration scripts. All scripts for managing batch processes must be completed and tested prior to migration.

--------------------------------------------------------------------------------

Choosing Full or Limited Migration
Accounts to migrate can be defined based on business rules (for example, all mail accounts in good standing or priority accounts requiring early access to features not offered in the exiting mail system).

If you are not going to migrate the entire population at one time, there are certain considerations you need to plan for. For limited migration, you must configure the Microsoft Exchange 2003 system for POP proxy in order to retrieve mail from the legacy system for unmigrated accounts and mailboxes. The architecture must also account for SMTP relay during Proxy mode in order to deliver appropriate mail to the legacy system as well as to Microsoft Exchange 2003.

The method of migrating account data must be identified and tested. Before the limited account migration can occur, a back-out plan, migration quality assurance, and certification of migration must be resolved and validated by testing.

In many instances, new subscribers to mail service at the customer site are added to the Microsoft Exchange 2003 system before migrated accounts from the legacy system. The benefits of handling new registrations in Microsoft Exchange 2003 are that you may be able to:

Offer differentiated service immediately.

Introduce Microsoft Exchange 2003 at a measured pace.

Ensure that no more users are added to an obsolete system.

Resuming Service
Once migration is completed, accounts are automatically switched from Proxy mode to active status. Users regain access to their mailboxes and all messages that were deferred during migration are delivered to their intended recipients. In addition, you must move operations entirely to the Microsoft Exchange 2003 system and deactivate the legacy system.

A burn-in period should be identified, over which the Microsoft Exchange 2003 system must be closely monitored for error conditions.

Using Migration Utilities
There are multiple methods for the combined migration of accounts and mailboxes. One method is to transfer all accounts in a single migration. Then, mailboxes can be transferred in batches. Another method is to transfer a batch of accounts, then transfer a batch of corresponding mailboxes, and so on.

Utilities that support the chosen strategy must then be developed and tested. These tests should include timing of the execution of these utilities.

This phase involves the building of the migration utilities themselves and must include the design, development, and testing of the migration utilities that are to be used to migrate the mail from the existing system to the newly implemented Microsoft Exchange 2003 system. New tools have to be built very often because of the different source mail systems that can be in existence.

Microsoft Exchange 2003 offers automated migration tools designed to streamline the process of moving your service, including built-in tools for services using Sendmail and Software.com's Post.Office. These flexible, modular, and customizable tools are Perl scripts that handle the export of directory, mailbox, and user information from these other systems to files in Microsoft Exchange 2003-readable format (based on LDIF), which are then imported into Microsoft Exchange 2003. These tools enable you to migrate all accounts at once or as incremental blocks of users. When migrating from a different mail system such as Netscape Messaging Server or SIMS, Microsoft Exchange 2003's proxy features and robust export command set provide a solid foundation for rapid development of custom export scripts.

Tips for a Successful Migration
With the completion of the migration tests, the only anticipated impact will be caused by the difference in functionality between mail systems. Once the migration of accounts has started, the target production environment becomes the production environment.

The migration procedure involves these discrete steps:

Setting up Microsoft Exchange 2003 in Proxy mode

Changing the MX record

Identifying accounts to be migrated

Extracting account information

Creating accounts in Microsoft Exchange 2003

Migrating messages

Setting Up Microsoft Exchange 2003 in Proxy Mode
Microsoft Exchange must be configured for Proxy mode prior to activating the system. The proxy configuration permits the relay of message and service requests to the legacy system until the full migration has been achieved.

In Proxy mode, all incoming mail is directed to Microsoft Exchange 2003. If the mail is for a user that does not have an Microsoft Exchange account, the mail is relayed to the legacy system for delivery. If a user attempts to retrieve mail, but the user's mailbox is not yet located on the Microsoft Exchange 2003 system, the POP server will connect to the legacy system and will retrieve the mail from the legacy mailbox location.

Changing the MX Record
In order for mail to reach the Microsoft Exchange 2003 system (instead of the legacy system), you must change the MX record in the DNS for the mail domain of the site, so that traffic is directed to Microsoft Exchange 2003.

With all of the mail directed to Microsoft Exchange, you can begin to burn-in the system with live loads and become accustomed to operations administration even if there is no account data in the system. However, as soon as the system is activated, accounts are provisioned directly into Microsoft Exchange 2003.

--------------------------------------------------------------------------------

Note: This step can take a few hours to be propagated over the Internet.

--------------------------------------------------------------------------------

Identifying Accounts to Be Migrated
The first step in migration is to determine which existing mail accounts will move to the Microsoft Exchange 2003 system. Accounts to migrate can be defined based on business rules (for example, all mail accounts in good standing, or priority accounts requiring early access to features not offered in the existing mail system).

Extracting Account Information
After defining the accounts to migrate, the next step is to extract account information from the existing mail system. Using the target account list, account information is exported into a file in LDAP Data Interchange Format (LDIF). The standard LDIF format permits the importing of account information from any existing mail system to an Microsoft Exchange system. The scripts used here can be customized to handle any situation.

Creating Accounts in Microsoft Exchange 2003
Next, accounts are created in the Microsoft Exchange directory based on the account information described in the LDIF file. As accounts are created, they are placed in Proxy mode, causing mail delivery to and access from unmigrated accounts to be passed directly through to the old mail system, thus ensuring continuous service to end users. During this phase, if a user logs in and supplies an unknown username, the Microsoft Exchange POP server connects to the current e-mail system.

Migrating Messages
The last phase of migration involves moving mail messages from the existing mail system to the Microsoft Exchange system. Message migration may occur either as separate files or as a single, concatenated file. However, some customization is typically required, since the way a message is stored in the Message Store Server (MSS) can differ from the standard mail format. This phase requires new accounts to run in Maintenance mode, during which time these mailboxes are unavailable. For this reason, message migration is typically performed in small increments during off-peak hours.

Exchange Migration plan for moving forward:

Perform Due Diligence on your network via Remote Terminal Service ( Next Week)

Colonizing The World: Prehistoric Migration Issues


Author's Note: The situations inside are the ones of a time-frame from more or less thirteen,000 to 200,000 years earlier than the present, and consequently way earlier than the era of agricultural settlements. We're coping with our nomadic hunter-gatherer ancestors here. Key dates are: African origin of contemporary people, Homo sapiens, at about two hundred,000 years in the past; an Out-of-Africa migration commenced kind of 70,000 years ago; our global colonization (except for Antarctica and Oceania) became completed by 13,000 years in the past.

When it comes to humans, right here described as Homo something or different, no longer always just Homo sapiens, colonizing the sector from Ground Zero, it truly is Africa, properly several issues arise.

Humans (as in Homo sapiens) originated in Africa and some in the end did, slowly, ever so slowly, migrate Out-of-Africa (no longer that they virtually have been privy to this), eventually spreading out and colonizing the world (aside from Antarctica and Oceania east of Australia and west of South America) by way of at the least thirteen,000 years in the past. Exactly how isn't completely understood, least of all with the aid of me. The primary, but no longer exclusive, issue I even have is with recognize to our approaches and way of buying and selling in being solely nomadic land-lubbers for obtaining sophisticated maritime abilities as well; skills required if our international colonization state of affairs is to be believed.

Problem One: Boats Required but No Show-Boats Found

When it comes to human migrations, there are certain lands which have been colonized by means of each Homo sapiens and Homo erectus that involved crossing fairly huge expanses of ocean - good sized at least for those cultures that existed over 60,000 years ago, when, for example, Australia changed into colonized by using what is today known as the Australian Aborigine. Even earlier, Homo erectus island-hopped the severa Indonesian islands as attested to through fossil evidence. In each instances, those historical cultures had to have obtained rather full-size boat-making, crusing and navigation abilities that might allow a large sufficient population to pass over the ocean waters, in view that even throughout Ice Age conditions, these Indonesian islands, and Australia, had been still remoted with the aid of oceans.

Sailing the oceans blue: that is a pretty big ask for primitive humans all those tens upon tens of lots of years in the past. But, there is every other manner of crossing the ocean blue - we do it all of the time these days. We don't sail, we fly. Perhaps our ancient ancestors had been flown to Australia and the Indonesian isles! Since aerial generation is even greater outlandish than maritime technology, properly, possibly the aerial technology belonged to advanced beings - historical extraterrestrial beings or historical astronauts. One other remark in favour - there are fossil reveals of this or that hominid species at A, B & C. Alas, geographical points A, B, & C are separated through heaps upon lots of miles. No fossils are discovered at any points in-among A & B, or B & C. An apparent clarification, they did not migrate among A & B and B & C at several tens of kilometres in line with generation; they have been flown from A to B to C, for this reason explaining the shortage of fossils in-among - but greater about that rapidly.

Sooner or later to your nomadic hunter-gatherer wanderings you will intersect the beach! Rivers and streams you may wade across or swim throughout, perhaps use a buoyant log to keep directly to if want be. Lakes may be walked around. But the sea!!! The oceans offshore must had been terrifying to our very historical ancestors, and rightly so. The ocean is nothing if now not unpredictable and dangerous: from huge waves, gales, riptides, robust currents, razor-sharp rocks and shoals, sharks, jellyfish, hypothermia, and just all styles of unknowns lurking below the surface to feature on your terrors. The tides have to have seemed to be a merely supernatural manifestation, without herbal clarification, an unexplainable movement of the gods one way or the other announcing "that is our domain, hold away".

Would you instead be excessive and dry 10 miles inland or 10 miles out to sea seeking to maintain your head above water and no longer finishing up as fish-food? It takes manner much less attempt sit down on the beach than to swim or sail in or on the sea, and it's lots safer too!

Further, in most instances without a other land in sight, you haven't a clue what is on the opposite aspect of the sea, if some thing (maybe it goes on forever and forever), or how some distance across it's far to the alternative aspect, and in any event you and your band of nomadic hunter-gatherers have more urgent needs, like locating present day food and this night's shelter. The coastlines and beaches gives an abundance of food stuffs and resources: shellfish, crabs, turtles, seals, seabirds, fish, even seaweed (dried for gasoline). Coastlines and beaches are appropriate.

Are you without a doubt going to stop, make a raft and pass crusing out into the pure unknown out of natural interest, even though curiosity you likely have? No, in the every day hunt for survival you'll probable forget about the ocean and simply comply with the shoreline - which ultimately will deliver you to maximum locations. If you return to an impassable barrier, it's probable easier and a ways more secure to trek inland for awhile than divert resources to swimming or rafting around the barrier with all the risks that would entail. In any event, it's no longer all that east constructing and sailing and navigating a seaworthy boat or raft from scratch without any on hand-dandy how-to guide available. Further, you can not drink the seawater so freshwater might must be carried on any hypothetical voyage. Do you have leak-proof boxes? If so, how much do you need to take? Who is aware of?

There are four viable or realistic routes out of Africa. Even at some stage in the Ice Ages whilst sea ranges were decrease, three involve an ocean crossing, which, I recommend our ancient ancestors might keep away from. I suppose it's miles a ways less complicated, and safer, to just comply with the coastline, so I opt for the only land direction, up the west coast of the Red Sea and on up either into the Levant, or backpedal the east coast of the Red Sea and on into Arabia. You can observe the African coastline 'Out of Africa' and finally reach China, but not Australia, or Japan, or lots of S.E. Asian islands, the Channel Islands (off Southern California), Sri Lanka, and so on. Yet you discover historic human and human artefact remains in those locations, so our migrating nomadic ancestors glaringly did build boats or rafts and sail the ocean blue and fulfill that curiosity, however the real why is unexplained - interest isn't purpose enough to place your self in harms way. The fly in the ointment, in any occasion, and unfortunately and alack, there are not any boats or rafts to be determined, actual stays or pictorial representations, within the prehistoric archaeological record. Boats and rafts are all in all likelihood boats and rafts; boats and rafts are assumed but now not confirmed with the aid of any real proof. It's a sort of 'Catch-22'. Boats and rafts have to be, but we cannot locate them!

It ought to be stated that due to the Ice Ages, historical coastlines then are actually underwater and probably applicable telltale archaeology (as in stays of boats) is therefore also underwater. Even so, the issue stays that I locate it difficult to consider our historic ancestors might have been brave enough to paste their feet within the oceans with out a rattling correct motive, but, there were places colonized with the aid of early man that even at the height of the Ice Ages there existed no land bridges for them to go over, say to Australia, New Zealand, Oceania, Japan, lots of S.E. Asian islands, and presumably lots of different islands, huge and small. Conclusion: That's a huge anomaly that desires a decision.

Problem Two: Paradise Lost

Crossing the oceans blue is just the start of anomalous migration problems. If cash, language boundaries, cultural differences, political structures, passports and visas, and so on. Have been of no problem and you could journey to and live anywhere you needed, wherein wouldn't it be? Well, probably someplace no longer too warm, now not too bloodless, not too wet, nor too dry, an area where there are plentiful natural assets of food, sparkling water, wooden, stone, and likely some kind of ascetically appealing surroundings, etc. With the exception of the surroundings, all those other geographical and climatic factors would be even more pressing for our historic ancestors without a access to supermarkets, hardware shops, air conditioning, relevant heating and tap water on demand. So the query arises, given a lack of population stress manner back whilst, a loss of stress no longer riding migration faraway from paradise and toward hell, why did a number of our ancient ancestors undertake a nomadic lifestyle in what we would consider excessive environments, like arid areas, the tundra, and so on.?

Unlike cutting-edge visitors, when our very far flung ancestors roamed the plains of Africa, their nomadic wanderings or migrations had been not geography directed. In an technology where there has been no radio and TV, newspapers and magazines, GPS and the Internet, encyclopaedias and journey agents, there has been no understanding of what changed into over the hill, past the horizon. Food availability directed your travels and migrations. You exhausted one patch of turf - you moved on to the subsequent, and the following, and the following in a type of random drunkards stroll. Logic dictates that even so you did not wander out of paradise or a purpose facsimile thereof. But finally, like a drop of ink diffusing thru a pitcher of water, the rest of the arena, paradise, hell and factors in-between, got invaded by means of our African out-of-towners - an invasive pest species that become to carry general death and destruction of their wake, but it's another story. Anyway, why we colonized extremely hostile environments when more satisfactory alternatives had been to be had wishes a decision.

Problem Three: Connect the Dots

There are two fundamental forms of clues that reveal our possibly migration patterns. Firstly, there are those archaeological web sites and from those educated professionals you possibly can normally deduce what hominid species become gift and from various courting methods, whilst. The problem is that such websites are all too few and a long way between. So, perhaps you've got an Australian Aboriginal web site around the Perth place (S.W. Coast) dated to mention 30,000 years ago. Then say you have another website across the Sydney area (S.E. Coast) dated to twenty,000 years ago. So the belief is that some Aborigines migrated from Perth to Sydney over the 10,000 12 months c language. But there may be no sites in-between, so you don't in reality recognize if they migrated in a straight line between the 2 areas or turned into all of it only a overall zigzag. Maybe neither if there's yet an undiscovered 1/3 web page, say in Darwin (mid-North Coast) from forty,000 years ago, and some Darwin Aborigines followed the west coast course to Perth taking 10,000 years and a few others the east coast trek to Sydney taking a span of 20,000 years. You can pretty much join the dots anyway you rattling properly please if it gives proof to your pet theory.

The 2nd line of evidence is the usage of mitochondrial DNA discovered in current humans to try and work again migration routes. For instance, if mitochondrial DNA in modern-day Australian Aborigines has a closer mitochondrial DNA healthy to fashionable Indonesians than to trendy Fijians, then one may conclude that the Aborigines migrated to Australia from Indonesia and not from Fiji. I individually don't like this form of genetic evidence. Firstly, DNA mutates over the years. Evolution would be screwed if it did not. Secondly, there's been an lousy lot of comings and goings because those initial Out-of-Africa migrations began. Thirdly, there is been an awful lot of breeding between the races so that by means of now hardly ever all of us is 'natural' something. Still, the specialists positioned plenty of religion within the checking out, so who am I to dispute their methods and approach?

So, how do you get from Point A to Point B tens of hundreds of years in the past when Points A and B are separated by way of enormous ocean distances? Why do you go from Point A to Point B when Point B is surprisingly unwanted? How in truth will we honestly recognise that Points A and B are the be-all-and-stop-all of start and finish?

Let's say Point A is adorable Hawaii, and Point B is the huge arid barren region of outback Central Australia. How do you get from A to B? You cannot walk and observe the coastline. You can not pressure or experience a horse. You should build a ship and sail but that's a hell of a leap of braveness you have to master, and in any occasion you have not any concept what route to head in or that Australia even exists. And even if you did, why would you need to depart Hawaii (Site A) for the Australian Outback; and in case you did attain the Outback (Site B) why would not you switch right around and head lower back to Hawaii again?

Well, you can be flown non-prevent from Hawaii to Central Australia. We crossed over ocean obstacles because we have been airlifted over them. You might be flown to Central Australia and stranded there. For the identical cause, we did not voluntarily undertake the tundra as domestic - it turned into compelled on us as an adapt do-or-die test. Flight might also give an explanation for the lack of applicable archaeological web sites between A and B. If our historical ancestors nomadically walked lots of miles between Point A and Point B, you'll anticipate archaeological evidence to be determined along the assumed connect-the-dots path. But if you fly, or are flown, then of course you wouldn't discover any in-among websites containing any applicable archaeological proof.

Southern California Dry Lakes Racing history


Southern California...I've heard it described as "extended barren region parking to the beach." but it didn't continue like this. Some 18,000 years ago, elements of So Cal had large inland lakes. The whole thing modifications are given enough time, and nowadays those lakes are long empty. They're now Southern California's dry lake beds. So why write about geology in an editorial about cars? I am just setting the returned drop for one of the maximum thrilling durations in the improvement of Hot Rodding. Examine my pals and find out some cool vehicle history!

Southern California's dry lake beds, locations like Muroc, Harper, Rosamond, and El Mirage have attracted automobile racers given that the start of the 1900s. Shortly after some man made a couple of modifications to his vehicle, he commenced searching out an excellent location to test them out and no longer be disturbed in the system. Those dry lake beds suit the invoice to a "T," pardon the pun!

by means of the Nineteen Thirties, set up dry lakes racing started to adapt in response to several factors. young men with mechanical ability and a love for tinkering with their considerable and reasonably-priced mission automobiles had been assembly each different, organizing into golf equipment, and racing to see what the repay changed into for all their efforts. Racers from the L.A. and Orange County area started to "centralize", walking their automobiles at the Muroc dry lake. due to its length, Muroc became the earliest popular spot. It sooner or later were given taken over when Edwards Air force Base changed into built. Racing persevered to grow, despite dropping Muroc. other famous sites sprang up (Harper, Rosamond, and later El Mirage) to fill the gap for an area to run cars.

Injuries and accidents were unfortunate (and unwelcome) ed81d2c1d705861968d8963ac974ba36 of this young interest. The Southern California Timing affiliation, begun in 1937, was the result of several golf equipment cooperating in the hobby of an agency, safety and preserving the neighborhood government off racers backs. In those days, most of the motors running at the lakes had been street cars. Once there, off got here whatever that did not make an automobile "now." some racers went to extremes, substantially Dick Kraft, who pulled off the frame and sat on a board over the rear end while racing in a washing match!

Changes, like swapping carbs or running alcohol became common. The Ford model A and B four-cylinders had been the engines of choice. Two or 4 port overhead conversions were carried out on them. The SCTA Racing news identified automobiles through their heads (Winfield, Riley, Cragar, and others). In the beginning, four-bangers held their personal in opposition to the more modern V-8 Flatheads, ordinarily due to the quantity of pace gadget that existed for them. However, records suggests that shear size gained out in the end and 4's gave way to 8's quickly.
