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.

Judging by Appearance – It Happens in the Workplace This is one of the old sayings that really does come true, the clothes do make a person. What does it mean? For many people, it means that people judge by the clothes you wear. This is especially true in the workplace, but also for everyday life. Many companies nowadays have a dress policy in place to keep the appearances at work up. Reasons why companies have dress policies are of a great variety. Here is a review. One of the biggest reasons for companies to require nice appropriate clothing at least in their office area is visiting customers. If your employees need to be in contact with customers on daily or weekly bases or if customers do visit your offices in general, it is important that your employees make a good first impression. First impressions are very much guided by what you are wearing, your facial impressions and body posture. Therefore, if your customer see your employees working on their desks, it is important that the employees are dressed appropriately. For most workplaces this means a button down or polo shirt, dress pants or casual dress pants. In some instances, it is important for the employees to wear a tie and suit. For women, the codes are equivalent what the style of the clothing is referring to. Imagine what would happen if a customer comes into a company and the employee receiving the customer wears dirty, spotty, old and ripped clothes. In society that does not make a good impression, then the customer will most likely not want to do business with you. Another reason of why companies and employers would judge by your appearance is called professionalism. In the picture of professionalism at the workplace includes good appropriate clothing. It belongs to being a good employee as much as doing your job right and being polite and respectful to your boss and colleagues at your workplace. In society much is judged by the way you dress. If you have ever walked into one of the better department stores with a set of old, worn clothes, what kind of response do you get from the sales person? Often times they think you do not have enough money to buy here anyways and that is the way they treat you. They may not even give you the time of day, even if you have a lot of money. They judge you by what you have on and this is certainly the case in the workplace as well. If you want to project a good image, then take a good look at what you wear before you step out of your door in the morning. There are many places where a dress code is required or expected, such as the church, the opera, the theater, better restaurants and many other places. The workplace is just one of many and whether you like it or not, appropriate clothing is what can make or keep you get the job. Many Internet sites, books and people that offer advice on interviews and getting that job, will emphasize the importance of nice appropriate clothing and the impact it can have when you wear something that stands out from the crowd. Most people have been raised to think that proper dress attire is what you should wear at work, but for some it still is more a mystery to them than anything else.

Preparing Questions to Ask in your Upcoming Job Interview When you get ready for a job interview, chances are you have spent a lot of time trying to guess the questions you will be asked and prepare your answers to them. How will you explain that gap in your work history? What will you say when they ask you why you left your last job? In the rush to make sure that you have all of your answers perfectly prepared and ready, don’t forget to prepare a few questions of your own to ask the person who is interviewing you. Asking questions is an important part of your interview. When you get asked the old “do you have any questions for us” one, it pays to actually be able to come back with a few questions instead of a, “no, I don’t think so.” Asking questions will show that you are engaged in the interview and have done some thinking about the position, plus, the questions you ask will help you elicit valuable information you need when you have to decide whether or not to actually take the job, should it be offered to you. The first thing you should want to find out is why the job is open in the first place. Is the job you are applying for a new position? That means you can expect to have a lot of transitional bumps along the way as you are integrated into the company. If the job is not new, and the person before you was fired, then you can expect things to be in a state of disarray when you take over and that you will have to spend a lot of time up front cleaning up spilled milk. If the job is open because the person who had it before you moved up in the company, then you will know that this is a job with a lot of future potential. Next, find out a little bit about the person who will actually be your boss if you get the job. Sometimes, this person will be involved in the interview, but often they will not. Finding out how high up in the company chain you will be reporting will help you gauge how important the position for which you are applying is to the company. Also, it helps to know a little bit about the personality type of the boss to be. If you like to keep your head down and do your work, and your potential new boss is one of those “wacky” types, then you may want to look elsewhere. From there, ask about the kinds of responsibilities you will need to take on board right out of the gate. When companies are hiring for a new position, they usually have a few ideas about what that person will need to start working on right away. Getting a clue about your first project will help you decide if this job is right for you. This is also a good time to ask the interviewer about their job and why they like working the company. You may find out that this really could be your dream job, or you may end up sensing from your interviewer that you should run away, fast. Last but not least, ask your interview when you should follow-up on your interview. Don’t open the door for a “don’t call us, we’ll call you” kind of interview closing. Let the interviewer know to their face that will be making the effort to contact them again. You may get the vibe from your interviewer that the job probably will be going to someone else, so you can move on quickly, or you may end up being offered the job on the spot. Either way, you will have opened the lines of communication to take the next step.
