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.

Staying Computer Safe while Searching for Freebies on the Net Who doesn?t love the idea of getting something for nothing? Free stuff can bring a smile to anyone?s face, and the Internet is destination number one when you are looking for cash in on a few freebies. The downside of free stuff online is that if you aren?t careful, the free item could end up causing plenty of headaches and heartaches, not to mention a lot of cold, hard cash. If you want to score with free stuff online, make safety your number one priority by following these tips. First and foremost, treat your personal information like its cash. That might sound a little dramatic, but anyone who manages to steal your identity online is after one thing, and one thing only, your money and any addition money they can grab by cashing in on your credit. Protecting your name, address, credit card number, bank account number, phone number, social security number, and so on and so forth when you are registering for free offers is the first step to making sure you don?t get hustled when you?re just trying to enjoy a good freebie. That means that if you are asked for some personal information that you don?t feel comfortable handing out, let the freebie go. Likewise, make sure the site from which you are getting your free stuff has a privacy policy and that you know it, understand it, and can live with it. Speaking of that site that is handing out the free goods: just who are these people? If you were walking down the street and a shady looking person said they would give you a free DVD player if you followed them, chances are you would run the other way. Online, it is hard to tell the legitimate people from the people looking at you like a free lunch, but there are a few red flags you can look out for. Does the website look like it was thrown up in about 5 minutes, full of clip art and bad spelling? Is it hard to find information about where the website is registered, or where the business the website is supposedly promoting is registered? If the website purports to be affiliated with a certain brand you know, does it really look like it is, or does the logo look different/colors look off? If you can?t get a reasonable feel for who are dealing with online, don?t deal with them. Red flag number one? Asking for too much personal info should send you running. Another way to protect yourself is to build a virtual fortress around your computer. The net is filled with people who know how to walk right into your virtual home ? your computer ? and flip through everything you have on there, taking whatever they want. Many of these kinds of hackers draw you in by creating phony freebie websites. The way to keep them out is to keep your computer on lockdown. Make sure your firewall is stronger than you think it needs to be, and make sure it is always updated. Also, make sure you have antivirus software on the patrol for you and that you keep this software updated as well. Last but not least, keep those passwords in the vault, and make sure they are extra strong. No freebie website has any reason to ask you about the passwords for your accounts so don?t give them away ? and don?t give them to anyone else online for that matter. Also, if you?re using your birthday or child?s name as password, don?t. Sure, it isn?t as easy to remember, but your password should be a random word and contain a collection of numbers and symbols as well. This will give you the extra layer of protection to make sure your online house is in order when you cash in on the freebies.

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.

Definition of copyright infringement Protect Yourself: Know the Definition of Copyright Infringement As you?re creating something, you may wonder what copyright infringement actually is. It?s necessary, if you?re creating a work ? albeit written, musical, videos, software or some other form ? that you know the definition of copyright infringement. This issue is very complicated, and not very easily spelled out in plain English, so please make sure that if you?re ever unsure to contact a copyright lawyer immediately to ensure you?re using copyrights in a legal method appropriate to the medium. As I mentioned earlier, a definition of copyright infringement is difficult, at best. Copyright infringement is defined by the jurisdiction ? the United States of America has different copyright laws than the United Kingdom, or Australia, or Russia, or even China. Because of this fact, you should first, before anything else, check the laws in your jurisdiction (country, city & province) before using something that isn?t in the public domain. For our definition of copyright infringement, the public domain is a place where works are that aren?t copyright-able. Works that aren?t copyright-able include ideas, works that aren?t eligible (150 years-old documents, or older ? think Beethoven and Frankenstein), data that isn?t categorized in a creative way (this could be a database, such as a phone book or other publicly-accessible data), or items that the owners have specified creative commons copyrights. As you can see, copyright law is rather complicated. Wikipedia.org gives us the definition of copyright infringement as: ?Copyright infringement (or copyright violation) is the unauthorized use of material that is protected by intellectual property rights law particularly the copyright in a manner that violates one of the original copyright owner's exclusive rights, such as the right to reproduce or perform the copyrighted work, or to make derivative works that build upon it. The slang term bootleg (derived from the use of the shank of a boot for the purposes of smuggling) is often used to describe illicitly copied material.? Our definition of copyright infringement includes the works of creative commons. Creative commons is an organization that allows for the copyright author to determine the uses available for people who want to use their works ? for such items as for audio, images, video, text, educational materials, and software. It allows for the copyright owner to allow people to use their works for non-commercial, commercial, no derivatives, share alike, or just by giving attribution. Creative Commons is a license granted by the copyright holder, and can be used in both online (electronic internet) works and offline works. There are many places you can go to get a definition of copyright infringement. The most reliable definition of copyright infringement would be from your local copyright lawyer ? they will know exactly what in your jurisdiction is legal or not, and how you can use other peoples? works or protect your own. The real definition of copyright infringement comes from your jurisdictions statutes. In the United States of America, our jurisdiction?s copyright laws are contained in Title 17 of the United States Code, 501 - 513. You can also find a definition of copyright infringement through such organizations such as the European Union or World Trade Organizations. While s legal country or organizational definition of copyright infringement is hard for the layperson to understand, a copyright lawyer will help you to figure out what it is that your work needs to be protected against copyright infringement, or to protect yourself if you intend to use the work of another writer, director, or musician.
