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.

Five Biggest Job Hunting Mistakes and How to Avoid Them Looking for a job can be a challenging experience. Between the resume writing and the interviews you can find yourself exhausted and ready to throw in the towel prematurely. Stay the course until you find the job you want. While you are on your job-hunting journey, here are five big mistakes to avoid when job hunting. Steering clear of these mistakes could make finding a job much easier. One of the biggest mistakes that people make when they are job hunting is not looking in enough places for jobs. There is a certain level of diligence you need to maintain when you are searching for a job. Look in newspapers, online and ask around. Of course, there are boundaries you should follow when looking for a job. First of all only apply and interview for jobs that you think you would take if you were offered the position. Do not apply for jobs that you are not qualified at all for or jobs that you do not have a clear understanding of. When applying for jobs, it is important to have a resume that is update and professional looking. If you are not a good resume writer, look at examples online or find a professional to do your resume for you. Employers will take one look at a messy or unprofessional resume and rule you out without ever meeting you. It is also important to be sure that you resume can be found online. There are plenty of job sites that allow users to post resumes. Some sites even allow multiple resumes to be posted. This is a great place for employers to locate your resume and contact you without you actually applying for the job. Lying on your resume can eliminate you from being a job candidate immediately. If you stretch the truth about your experience or the type of jobs you have had in the past, employers will think that you are a liar. If employers think you are a lair they will not feel confident about hiring you because you have already compromised your integrity. Tell the truth about your work and educational history. No matter what people may tell you, an honest inexperienced candidate is better than a lying experienced candidate. Have faith that you will be able to prove your worthiness for the position you are applying for without making up half-truths. Be sure that your contact information is correct and that you respond when you are contacted. No matter how busy you are, you need to check your e-mail and phone messages on a regular basis. If you do not respond to a call about a job this is a sign that you do not need employment that badly. Employers will move on to the next candidate if you are slow getting back to them. Candidates that are not prepared for their interviews are typically eliminated from the search before the interview is over. If you are late for an interview you have a big huge mark against you as soon as you walk in the door. Not being dressed in professional attire also will leave the interview with a very bad impression of you before you even speak. If you show up without a pen or copies of your resume you look like you are unfamiliar with the interview process. This, in turn, makes it quite possible that you are unfamiliar with other work place procedures. A good job hunt can land you the job of your dreams. When you are settled into your new job you will be thankful that you took the time to search for a job the right way.

Software copyright Software Copyright Difficult to Enforce For those of you who love computer games, you probably know more about software copyright than you ever thought you'd want to know-especially if you have or have ever owned multiple computers. Most new games not only come with special copyrights but also built in security features that are designed to enforce those copyrights. Some have even gone so far as selling you the right to 'use' the material you are purchasing rather than providing you with actual ownership of the software to which they own the software copyright. That bothered me a bit at first, but I've come to understand it's another way of protecting them and their rights as well as controlling or limiting how you use the software they provide. Software copyright is actually quite confusing and hotly debated. Many stores will not accept opened software as returns because the software companies won't reimburse them for the product and they are left holding the bag. It doesn't sound like much but when you think of literally thousands of consumers attempting to return opened software because they didn't like or worse, they only needed to download and install it for it to actually run. Companies that produce computer software have become savvy to the ways of the modern consumer. Those companies that produce computer games especially require that the disk actually be in your player in order for the game to operate properly. This enforced the software copyright to the extent that two people can't reasonably share ownership of the same game, as they both need an actual disk in order to operate the games. But for every solution there is a hacker or budding programmer that creates a new problem for software makers and holders of software copyright to face. One of the latest problems is the virtual CD. The long and short of this is that the computer is tricked into 'seeing' the CD where it should be and carries out the game as though it were. Another important thing to note about software copyright is that there are many programs available that mimic some of the more notable applications for no fee. These are often referred to as open source software and often have excellent if not superior quality to similar programs that are available for fees. One thing I've noticed is that I will often find free open source software, download it, love it and a few months later I will find a more polished version of the same software, by the same company available with a few more bells and whistles for a fee. The new improved software has a software copyright and is not free to consumers but it is also a much better version than what I currently have. It's a great way for new software developers to make names for themselves and get volunteers for the testing process of their development phase. A software copyright offers protection and recognition to the owner of the software. The problem with protecting software is that it is impossible to police properly. That would require walking into every home on the planet and checking each computer to make sure there are no duplicate copies extra copies, illegal copies, etc. Plus, who keeps the actual boxes from all their software? I certainly do not. I could never prove that I was honoring the software copyright if the packaging or receipts were the only way I have of doing so. Most people in the world today honestly want to do the right thing. Software is one of the most expensive purchases people will often make for their home computers, it only makes sense to buy actual copies that have an actual software copyright in order to protect your investment not only in your software but also in your computer.
