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.

How to Work the Internet to your Advantage in a Job Search Are you on the hunt for the perfect job? If you need a new job and you are spending every day running out and buying a paper and flipping through the classified ads, you are way out of date. The newest way to find a job is to use the Internet in your job search. After all, nearly everything else people do these days is done online, so why not looking for your next job. The best part is that the Internet is much better than the classified ads in your local paper when it comes to finding a job you love. When you search for a job online, you have a world of employment opportunities right at your fingertips. There are many ways you start your search for jobs online. There are several websites that are dedicated just to job hunting. On these kinds of sites, you can search through a database of literally thousands and thousands of jobs until you find some that appeal to you. Most of these websites let you search for jobs using many different criteria, from job location to job field to starting salary to jobs that let you work from home. These websites can be a wonderful way of getting a feel for what kind of jobs are out there and what the going rate of pay is for any job in any industry, and how that pay fluctuates regionally. In addition, these sites are also ideal if you are thinking of moving, and want to move to someplace you can find a job. If you don’t care where you move, you can look for cities where the job market is hot. If you know where you want to move, you can look for jobs in your desired city and get the inside track on the job market from no matter where you are. Additionally, on these job listings websites, you can upload your own resume to the site. That way, you can apply to jobs through the website with the click of a button, and potential employers can find you when they are looking for someone with your skills. Another way you can use the Internet to your advantage when you are hunting for a job is to build your own job hunting website. Create a website that showcases your resume and all of the work experience you have. You can set out your career objectives and show off any special skills you have. Having your own website is a great way to direct potential employers to where they can find more information about you and is a handy way of getting the message across about skills or achievements you have that may not be right for inclusion on your resume. If all of this sounds like casting the net a little too wide for your tastes, the good news is there are now local job listings websites in most towns. These websites work in much the same way was the larger job hunting websites, but they only list local jobs and only allow local workers to upload their information. Remember that the Internet cuts both ways when looking for a job. Just as you might Google a potential employer, so they may Google you. Be thoughtful about what you post about yourself on the Internet. If you don’t want your potential boss to know about that time you had too much to drink and passed out in your friend’s front lawn, don’t post the picture online. Likewise, be careful when blogging about political, religious or off-color topics. Almost anything you say online can be traced back to you, and may be used against you in a job hunt.

Assistance on Filling Out those Online Forms for the Free Stuff So, you’ve found a great freebie online, or a free trial of some service you have been wondering about, but the form you have to fill out has left you scratching your head. Sometimes the paperwork involved in getting some free stuff can seem a bit like applying for a mortgage or filling out your life insurance policy, and in fact, many people decide the freebie isn’t worth it after all when they’re facing down an intimidating form to fill out. The good news is that you don’t have to miss out on the free stuff just because the form leaves you a little perplexed. This guide will walk you through filling out these online applications, even if this is your first trip around the Internet. Once you get the hang of things, you’ll be filling out these forms in no time at all. First things first: once you have the form open on the screen in front of you, you have to move your mouse so that the cursor sits in the very first empty space on the form, and then click the mouse once. Some forms will automatically place your cursor there when you open them, but if you are not sure, moving the mouse there and clicking won’t hurt anything at all. All you have to do now is start typing, filling in the information they ask for in that field. Filling out the form the entire form is merely a repetition of this process. Of course, you have to be able to move between the fields easily so you can fill in the rest of the form. On some online forms, the cursor will move automatically when you have finished filling in a field, which makes life easy on you, but others do not. To manually move between fields, all you have to do is either hit the “tab” key on your keyboard or use your mouse to move the cursor to the next field, just like you did to start typing in the first field. Hitting “enter” may seem like a natural thing to do, and while it can work on some forms, other forms will submit themselves when you hit enter, meaning you will have submitted a blank form. It is best to stick to “tab” or your mouse to be on the safe side. This technique should allow you to navigate a freebie form fairly easily. There are a few other things you may see on a form that you have to know how to handle. You may be asked to “check” a box or indicate in a little circle (called a radio button) that you accept the company’s privacy policy or some other thing. To do this, all you have to do is move your cursor over the box or circle and click – the check or the dot will then appear. This can also be handy when forms ask for a billing address and a shipping address - if they are the same, you can tick a box stating so and avoid having to type the same thing twice. If a form has several pages, be careful to save your changes for every page as you move along. Usually there will be a button to click at the bottom of the page that allows you to save the work you have done. Especially long forms usually have some kind of side navigation that lets you skip around from section to section instead of moving through the form systematically – this can be helpful if you need to find some info for one section, but want to take care of all of the other work first. Most forms are reasonably user friendly and contain info to walk you through the process. If you get stuck, look for a help icon on the page – this info should clear up any questions you may have.
