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.

People caught of copyright infringement Why Are People Caught of Copyright Infringement? When you hear of people caught of copyright infringement, many different things can happen to them. First of all, copyright infringement is both a civil and criminal crime, so people caught of copyright infringement are likely to get both sued and tried in criminal court. Because of the nature of copyright laws, if and when people are caught of copyright infringement, it’s likely that they will get repercussions from far and wide. First of all, people are always looking for people violating copyright laws. Copyright owners and/or agents surf the internet, so they may find the violations themselves. Usually, is someone finds that people are violating their copyright rights, they’ll notify the person or entities involved and ask that they take the content down, if it’s available on the Internet. They do this by either asking the person directly to take it down, or demanding of the website server to take it down (which they will, immediately, and probably suspend the account) If the person or entity hosting the violation doesn’t take it down, more serious actions will be taken, such as a lawsuit or criminal charge. People caught for copyright infringement do not automatically go to jail, although some entities like major television, music, and movie publishers and distribution channels may lead you to believe otherwise. For the example of YouTube.com, there are many people caught for copyright infringement, but they only need to take down the material. In many cases, YouTube.com will take the material down before the poster (the person who put the copyrighted information on the site to begin with) has a chance to see the warning. Other times, a work will be present on a peer to peer file sharing service, such as Kazaa or Napster, and the host of said service will blame the end user (you!). So, even if you found a file on a file sharing service, such as Kazaa, doesn’t mean the copyright is open for you to take it. Many people caught of copyright infringement have been found through these peer to peer networks, and it has been found time and again that the user that downloads the material gets charged and not the file sharing service. Be careful, if you are ever to use a peer to peer service such as Kazaa (or bit torrent, which is the code/program for another type of peer to peer file distribution tool) that you’re only downloading, and sharing, items that aren’t copyrighted works – or you could be punished severely. Sometimes, people are caught of file sharing from their IP addresses – because they download something from a secure site, their servers can track your IP address (your unique location on the internet, four sets of numbers, separated by periods, with at most three numbers in each set – i.e. 216.239.51.100 which is the IP address of Google.com). So even if you think you’ve bypassed the copyright law, you can still be found years later by tracing that IP address. There are many ways to find people caught of copyright infringement, you can search through Google.com or look through newspaper databases. One thing, however, remains the same in all these cases – the people are downloading, sharing, or in some other way using copyrighted materials. The only problem is, especially in the internet age, is that even if you’re using something anonymously, you can still be tracked – and prosecuted – for the infringement. Be careful, in all you download or use, have the rights to use the item – sometimes it’s as simple as asking permission that will keep you from getting sued or sent to jail.

Important Steps to Follow in Creating a Professional Digital Identity for your Job Search Having a professional digital identify is essential in finding new business or employment. Everyone can benefit from having a polished professional digital identity. It is key to advancing in any career. Of course, how you present yourself digitally depending on what type of career advancement you are going for. If you are starting a new business you will need to have a stellar website. A professional should consulted so that you have the best website possible. If you are interested in securing a new job, you can probably build your own website or just post your resume and portfolio. Trying to land an interview is much easier than striking out on your own so it takes a little less effort. However, no matter what your career aspirations are a professional digital identity is important. If your professional digital identity is lacking in credibility spend some time and effort improving it. A healthy professional digital identity will help you get the job you desire. Instead of spending money on business cards, invest in presenting yourself well on the web. People can always get in touch with you on the web. Business cards get lost in the shuffle of day-to-day paper accumulation that most people acquire. Locate all of the social networking sites you can. You can never be too well represented on the web. Of course, people like to shake hands and meet you in person. When circumstances permit, set up lunches or coffee dates to discuss projects or networking opportunities. For entrepreneurs, it is wise to stay well acquainted. The type of business you are in will influence what you have in your portfolio. If you are striving to build an online presence for your own personal business, have plenty of samples on your site. If you business is not one where you have samples to show, have coupons or special offers posted. Create a strong professional digital identity and you will attract more sales. Whether you are networking or building up business for yourself, you need to have a professional digital identity that people can respect. Provide a number of ways for people to get in touch with you and keep your information updated. Do pro bono if necessary. Do some things for free to gain exposure. First impressions have a big influence on what people think about you. In the past people were limited to physical or phone impressions. These days the way that employees first get to know most candidates is through their digital identity. A bad web site or a sloppy portfolio online can ruin your chances of getting a job. Make sure that your professional digital identity is well developed. One of the major mistakes people make when it comes to digital identity is registering for networking and social sites and posting less than favorable pictures and comments. Some employers check MySpace and Facebook to try to get a clear picture of the candidate they are interviewing or deciding whether or not to work with. If your Myspace page is full of pictures of you in your scantly clad bathing suit their decision to hire you or not becomes very easy. Do not use your real name to register for these types of sites. Or if you do, use the site in a professional manner. Set up your Myspace page in an attractive and professional way. Friends will be able to reach you but employers will also view you in a professional manner. A great way to present yourself well digitally is to have your own website. Upload your resume and include information about your work history. Employers will be able to review your work history more extensively making them more inclined to contact you.
