Web Hosting - Redundancy and Failover
Among the more useful innovations in computing, actually invented decades ago, are the twin ideas of redundancy and failover. These fancy words name very common sense concepts. When one computer (or part) fails, switch to another. Doing that seamlessly and quickly versus slowly with disruption defines one difference between good hosting and bad.
Network redundancy is the most widely used example. The Internet is just that, an inter-connected set of networks. Between and within networks are paths that make possible page requests, file transfers and data movement from one spot (called a 'node') to the next. If you have two or more paths between a user's computer and the server, one becoming unavailable is not much of a problem. Closing one street is not so bad, if you can drive down another just as easily.
Of course, there's the catch: 'just as easily'. When one path fails, the total load (the amount of data requested and by how many within what time frame) doesn't change. Now the same number of 'cars' are using fewer 'roads'. That can lead to traffic jams.
A very different, but related, phenomenon occurs when there suddenly become more 'cars', as happens in a massively widespread virus attack, for example. Then, a large number of useless and destructive programs are running around flooding the network. Making the situation worse, at a certain point, parts of the networks may shut down to prevent further spread, producing more 'cars' on now-fewer 'roads'.
A related form of redundancy and failover can be carried out with servers, which are in essence the 'end-nodes' of a network path.
Servers can fail because of a hard drive failure, motherboard overheating, memory malfunction, operating system bug, web server software overload or any of a hundred other causes. Whatever the cause, when two or more servers are configured so that another can take up the slack from one that's failed, that is redundancy.
That is more difficult to achieve than network redundancy, but it is still very common. Not as common as it should be, since many times a failed server is just re-booted or replaced or repaired with another piece of hardware. But, more sophisticated web hosting companies will have such redundancy in place.
And that's one lesson for anyone considering which web hosting company may offer superior service over another (similarly priced) company. Look at which company can offer competent assistance when things fail, as they always do sooner or later.
One company may have a habit of simply re-booting. Others may have redundant disk arrays. Hardware containing multiple disk drives to which the server has access allows for one or more drives to fail without bringing the system down. The failed drive is replaced and no one but the administrator is even aware there was a problem.
Still other companies may have still more sophisticated systems in place. Failover servers that take up the load of a crashed computer, without the end-user seeing anything are possible. In fact, in better installations, they're the norm. When they're in place, the user has at most only to refresh his or her browser and, bingo, everything is fine.
The more a web site owner knows about redundancy and failover, the better he or she can understand why things go wrong, and what options are available when they do. That knowledge can lead to better choices for a better web site experience.
Reinventing Yourself Can Make a Difference in Landing a Better Job Are you stuck in a dead end job that isn’t getting you any closer to your goals? Did you wake up one morning to find yourself knee deep in a career you never wanted and one that is not making you happy? Many people feel this way – it can be easy to “fall into” a career that you think is temporary and then get so caught up in the day to day aspects of the job that never quite get out of it. If you find yourself in this kind of rut, the good news is that it is never too late to make a fresh start. No matter what your age is or what stage in your career you are at, you can always reinvent yourself to get closer to that perfect job. All you have to do is work up the courage to make the jump. The first step in giving yourself a career makeover is identifying exactly what you want to do. While it may be true that there is always time to reinvent yourself and start over, if you have to go through the process too many times, you are only wasting valuable time that could have been spent doing what you love. Don’t fall into yet another career that isn’t all that is it cracked up to be. Think about the things that you wanted to do when you first entered the working world. What was your dream job then? What career field was your passion? Is it still what you want to be doing today? Discover your dream, and then start building your goals around it. Once you know what you want to do, the time comes to start researching it. How do most people get started in the field? Will you need to start your own business, or are there companies out there already doing what you want to do? What kinds of entry level positions are available? Will you be able to do this in your town, or would moving to another city mean more opportunities for you? Before you make the leap, research your job options carefully. You may need to plan financially for the step you are about to take, so do your homework up front. Talking to other people in the field you want to enter is a great way to get actionable advice from people who have been there. When you know what kind of experience you will need to get started in the field of your dreams, think about the experience you have had in the past, and what you have done that matches up. This can mean either work related experience or things you have done as a hobby or class you have taken in school. Be creative here – you may have experience you don’t even realize you have. For instance, if you want to open a bakery, and you are always in charge of the bake sale at your child’s school, this counts as experience. Comb through your history and pick out all of the things you have done that will give you a leg up in your new career. Last but not least, you have start creating a new image to present to the working world. Start over with a brand new resume, this time highlighting the experience you have this is relevant to your new career goals. Work on a great cover letter that explains your passion and why you want to switch fields. If you are starting your own business, work on building a website and creating a brand you can be proud of. The sooner you start living your new career, the sooner your dream job will fall into place.
Software copyright buy For Software Copyright Buy Locally To gain permission to use software copyright, buy the software. This sounds like such a simple solution and yet I know this isn't always as easy as it seems. Software is expensive, largely due to misuse and abuses of the past and the average consumer can't always afford to buy the software package and product he or she needs for business or pleasure. It is important when setting priorities for software purchases that you don't limit all your purchases to pleasurable pursuits. When making copyright software buy, be sure that you are getting the best possible product for your money. I've seen so many people spend foolishly for one product because it is the most common product on the market when another less expensive product would have been completely adequate at far less than half the price. Most people never use the bells and whistles they pay for when purchasing software. The best way to be sure that you are getting the best copyright software buy you can possibly get is to make a list of things you need your software to do, the things you'd like it to, and find all the software on the market that does those things. Find the one with the lowest cost and the most necessary features and let that be the software you decide to purchase. Don't make these decisions on the spur of the moment as you will almost always cost yourself more money in the long run. Another way to insure that you are getting a great copyright software buy is by comparing prices at local and online stores before making the purchase. You might be surprised by where you will find the lowest price (also keep in mind shipping costs when purchasing online they do swing the vote sometimes). Comparative pricing can save you hundreds of dollars in the course of a year on personal software and quite literally thousands of dollars each year on professional software. Be sure to make those decisions wisely as money spent poorly is money that could have been spent elsewhere. You should always remember when comparing prices and searching for the deal of the century when it comes to copyright software buy from a reputable source. This shouldn't have to be said but it really must be said. You would be amazed at how many people have received pirated software from purchases they've made online. This is an especially bad things for business deals in which the software was needed rather than personal software that was merely wanted and looked forward to. In business you could very well loose your investment in the pirated software as well valuable time getting the copyright software buy you actually needed in the first place. While the costs of doing business locally are often more expensive than it can be online I do recommend that for some purchases, particularly copyright software buy locally even if it is a little more costly. It's nice to know that there's a person on the other side if something goes wrong and that they want your business and want people in the community to respect their business. In other words local businesses are much more likely to give the personal touch and protect their reputations by doing the right thing. There are many other reasons that buying locally is good for you and your business buying needs. Buying locally for your business will establish your business locally (this is especially good if you don't have a huge presence or massive storefront from which to advertise). It also helps you make important business contacts in order to help your local business grow. For your copyright software buy locally to have some degree of assurance about the product you are getting.
Technical Writing: What is it? (technical writing) Technical writing is one of the most difficult forms of writing. To be a technical writer you need to be able to convey a technical message in a concise and effective manner. Technical documents must be created using comprehensive and precise information in a brief and understandable style. You will need the ability to be able to correspond with technical experts and have the understanding of all technical terminology. You are the middleman between the designers, engineers, or scientists and the audience of the technical writings. You have to have the ability to under stand what they are saying and the turn it into something that can be understood by someone else. Simply put it is writing that designs, creates, and upkeeps any kind of technical data such as user manuals, how to guides, and online help just to name a few. To be able to achieve a career in technical writing you must be able to write complex data in a straightforward, easy to understand and articulate fashion. You must be able to word step by step instructions in a way that seems effortless to a consumer. While doing technical writing one of the most important aspects of your job will be creating for an intended audience. So not only must you understand and convey what you are writing, you must understand whom you are writing it for. In most cases, you are generally trying to explain complex technical information to the average person. But with the diversity in the world today and having such a vast potential audience you must understand the meaning of the words you use and what they could mean to someone else. Some technical writing projects may also include magazine and newspaper articles. These articles will probably be focused on new technologies and products. In some cases this may be in the form of an advertisement. Or it could just be an introduction to a new product saying hey this is what we have and this is what it a can do. Although a formal education is always a plus, if you have experience and successful past ventures in technical writing it isn’t always necessary. Knowledge into the multiple components needed for technical writing is required. They key components to what you must know is an in depth knowledge many software programs. These applications can include Visio, Quadralay Web Works Publisher, Microsoft Word, and HTML script writing. Proper formatting, style, and organization of writings are what make them easy to follow. Correct wording, clear sentences, and easy terminology make your technical writings easy the read and comprehend. If you are employed as a technical writer with a company, you will most likely be working with a team of other writers. You writings will be reviewed for content efficiency as well as any grammar and spelling errors. Depending on the structure of the team they may be working on the same project as you or they may be working on separate projects. Either way the team is assembled as a support group to help make your technical writing be as accurate, effective, and as simple as it can be. To succeed in technical writing these are the simple rules to follow. Keep it as simple as possible; no one wants to read four pages to find a simple one word answer. Understand the people you are talking to and what you are telling them. If you don’t understand, neither will they. Make sure you get your work proofread or read it aloud to make sure it makes sense. You know what you are trying to say, but your reader does not. You are the carrier for getting information from point A to Point B.
