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.

Let your Resume Speak Volumes for that Next Big Job Before you even get through the door of any job interview, there is already one document that has done the talking for you – your resume. A good resume can mean the difference between getting the call of the interview and waiting by phone, and a well written, thoughtful resume can make you stand out over and above other applications with similar skills and work experience. Let your resume give you the edge on that next big job by following a few simple tips. When you sit down to write your resume, you need to plan it out before you start typing. There are two main formats for a resume: the chronological format, in which you simply list your job history, starting with your most recent or current job and moving backwards, and the functional format, in which you highlight your skills and experience rather than specific jobs and specific employers. The chronological format is definitely the most common, and many employers prefer this kind of resume, but choose the format this is going to show off your skills in the best light. If your work history is a choppy and a chronological format resume would only draw attention to that, use the functional format. The key is to choose the format that will give you the best chance of getting noticed for the job and to stick with the format throughout your resume. No matter which resume format you choose to use, the top of your resume should always include your name, contact information and work objectives. Name and contact information is pretty straight forward, although experts do recommend that if you have a “gender neutral” name that you include a helpful “Mr.” or “Ms” to clear up any confusion. Your work objectives should be your career goals. For instance, if you want to manage a small team of sales people, then say that, so your potential employers know that you are moving in a certain direction with your career and not simply apply for jobs willy-nilly. After your work objective comes your work experience. List your jobs in reverse chronological order. Instead of simply creating a bullet pointed list your work related tasks, look for a way to frame all of your responsibilities so that they sound like you showed leadership and problem solving capabilities. For instance, if you were in charge of keeping the expensive accounts in order, say that you were in charge of troubleshooting monthly expense account records, saving the company hundreds of dollars every month. If you have a few blips in your work history, be clear about what you were doing in the downtime. If you were raising children, traveling, or in school, say that you were. If you weren’t really doing anything, put as positive a spin on things as you can without lying. Never leave gaps in your work history unaddressed on your resume. After your work history, it is time to list your education credentials. If you didn’t finish a degree, say how much college work you completed and highlight any coursework relevant to the job. If your college degree or post grad work is in progress, say when you expect to be finished. This is another place where gaps matter. If there is a gap in your education history, again say what you were doing in that time, referring back to your work history where appropriate. You can overcome these gaps as long as you don’t pretend that they don’t exist. Round out your resume by listing any awards and professional memberships you may hold. Don’t get into your hobbies unless they are specifically related to the position for which you are applying. Personal details like religion and race have no place on your resume and you are not required to disclose your age. Instead, let your experience do the talking.

Yes, There Really is a Freebie Santa Claus If you are a cynic when it comes to offers of free stuff, you are not alone. Everyone has had notions like “there is no such thing as a free lunch” and “if it sounds too good to be true then it probably is” drilled into their heads, and for good reason – these things often hold water. On the flip side, there ARE actually lots of places you can score some decent free stuff, if you know where to look and are willing to devote some time to hunting them down. The key to getting the best free stuff with the least amount of hassle is to stick with that healthy cynicism but to also dipping your toe in the freebie pool little by little. But why would anyone give stuff away for free? It is certainly an obvious question, but if you stop to consider it for a moment, you can see that companies actually have a lot of motivation to give away free stuff. After all, if they give you something for free, you are bound to have a little soft spot for their company, and when you are ready to part with some cash, their product may near the top of your list. Also, by giving away free things, companies can convince people to try new products. You might not want to try a new kind of shampoo if you have to pay for it, but you’d certainly be willing to give a free sample a try. You may end up loving it and switching to that shampoo for good, turning you into a paying customer. Another reason a company might give you free stuff is to complete market research. This is where getting free things can get a little complicated for some people because the products may not cost you money, but the offer may cost you a little time. A company might ask you to take a survey of your buying habits before they give you a free offer, or they may ask you to provide feedback on a regular basis as you try their product for free. Some people balk at the time commitment required here, but for other people, filling out some paperwork is a small price to pay for some free stuff. Of course, to convert you into a customer or to communicate with you about market research, a company will have to contact you, which is complicated area number two for freebie lovers. You will almost always be forced to hand over your email address in order to cash in on a free offer, and that is a recipe for opening your inbox up to a barrage of spam (many companies sell your email address to offset the costs of their free promotions, which means the number of people soliciting you can go through the roof very quickly). If you want to avoid this downside of freebie hunting, set up a special email address specifically for your freebie deals. That way all of your spam goes to this one address and your regular email you use with family and friends remains free and clear. One final note of caution about free stuff online: a lot of scammers have hit on the idea of using pretend freebie offers to solicit personal information about people or to convince people to send them money. Don’t send money, even for postage, to a company you don’t know and never, ever give out personal information online. No reputable company is going to ask for your social security number or bank account details for a freebie offer, so don’t hand them out to anyone. When in doubt, skip it and move to the next freebie.
