Web Hosting - Unix vs Windows-Based Hosting, Which Is Better? An operating system functions largely out of sight, or at least is supposed to. It doesn't matter to non-geeks how a file gets stored, or how memory is used, or how simultaneous processes share the limited resources available on a computer. These are among the basic functions of any operating system. Yet, you can find very passionate supporters - who offer very detailed lists of pros and cons - for every operating system. Why? Because, though the low-level functions of an operating system do their work out of sight, there are many other features that rise to visibility. Sometimes, they do so when they're not supposed to. Weighing the pros and cons objectively could consume a book. But to select a web host operating system, a manageable level of considerations apply. They can be weighed even by those who don't know a processor queue from a pool cue. Learning Curves For most web site owners, administering the site/server is just overhead. It's not something they take pleasure in doing and they have plenty of other things to worry about. Many wouldn't know how and have no interest in learning (rightly so, given their priorities). Consequently, ease of administration is paramount for such people. Whether a Unix-based site (usually Linux these days) is easier to administer than Windows depends on your current skill set and the type of tools and level of access the web hosting company provides. But in general Linux is more difficult to install and maintain than Windows and the learning curve is steeper. FTP and Control Panels Often, you don't have to care. For many, the operating system is fairly transparent. FTP file transfers to get a new web page up to a Windows server are very much like they are to a Linux-based site. The user/administrator simply doesn't see what's behind the curtain. Many companies provide other utilities that completely mask any awareness of the operating system underneath. When that's the case, the web site owner has no reason to care, until or unless they need or want to go 'inside the black box'. Performance Performance issues can be relevant in selecting which operating system host type to choose. But for the most part, that aspect is outside the web site owner's control. Overall performance can be good or bad on either system, depending on many factors that the publisher will rarely see. The issue is a wash, as far as tipping the scales is concerned. What is more likely to be seen by a web site owner, at some point in their (and their site's) development is the database product that can be used to store information. Databases Microsoft SQL Server is relatively simple to use, yet extremely powerful and can deliver great performance. But it doesn't run on Linux. At least, not without special software to emulate Windows, which usually kills performance. On the other hand, with a bit of time invested, MySQL isn't significantly more difficult to learn than MS SQL Server and there are many free installations. Cost may well outweigh other considerations for most on this issue. Programming Languages Last, but not least, there are differences in programming languages that can be (or at least typically are) used on Windows vs Unix. If you have programmers who are skilled in Visual Basic, ASP and other Microsoft technologies, then a Windows-based host will be your preferred choice. For Perl and PHP programmers, Linux is the more common platform of choice. No single factor can push you to one versus the other operating system. And, in the long run, it isn't the primary consideration, unless you just enjoy playing with operating systems.

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.

Web Hosting - Changing Web Hosts, Pitfalls and Planning At some point, nearly everyone finds it necessary to change web hosts. It may be just a migration to another server, or it may be changing web hosting companies entirely. Either way, the process is fraught with potential dangers. But there are ways to minimize the odds of problems and maximize your changes of a smooth migration. Plan, plan, plan. Make a very detailed list of everything that is on your current system. Review what is static and what changes frequently. Note any tailoring done to software and files. Be prepared to remake them if the systems aren't transferred properly or can't be restored. Keep careful track of all old and new names, IP addresses and other information needed to make the migration. Backup and Test Backup everything on your system yourself, whenever possible. Web hosting companies typically offer that as a service, but the staff and/or software are often less than par. Often backups appear to go well, but they're rarely tested by restoring to a spare server. When the time comes that they're needed, they sometimes don't work. Do a dry run, if you can. Restore the system to its new location and make any needed changes. If you have the host name and or IP address buried in files, make sure it gets changed. This is often true of databases. SQL Server on Windows, for example, picks up the host name during installation. Moving a single database, or even multiple ones, to a new server is straightforward using in-built utilities or commercial backup/restore software. But moving certain system-related information may require changing the host name stored inside the master database. Similar considerations apply to web servers and other components. Accept Some Downtime Be prepared for some downtime. Very few systems can be picked up, moved to another place, then brought online with zero downtime. Doing so is possible, in fact it's common. But in such scenarios high-powered professionals use state-of-the-art tools to make the transition seamless. Most staff at web hosting companies don't have the skills or the resources to pull it off. Prepare for Name Changes One aspect of moving to a new host can bedevil the most skilled professionals: changing domain names and or domain name/IP address combinations. When you type a URL into your browser, or click on one, that name is used because it's easier for people to remember. www.yahoo.com is a lot easier to remember than 209.131.36.158. Yet the name and or name/IP address combination can (and does) change. Still, specialized servers called DNS (Domain Name System) servers have to keep track of them. And there are a lot of them. There may be only two (rarely) or there may be a dozen or more DNS servers between your visitors' browsers/computers and your web host. Every system along the chain has to keep track of who is who. When a name/IP address changes, that pair has to be communicated to everyone along the chain, and that takes time. In the meantime, it's possible for one visitor to find you at the new place, while another will be pointing to the old one. Some amount of downtime will usually occur while everything gets back in sync. The Little Gotchas But even apart from name and IP address changes, there are a hundred little things that can, and often do, go wrong. That's not a disaster. It's just the normal hurdles that arise when changing something as complicated as a web site and the associated systems that underlie it. Gather Tools and Support Having an FTP program that you're familiar with will help facilitate the change. That will allow you to quickly move files from one place to the next to do your part to get the system ready to go or make repairs. Making the effort to get to know, and become friendly with, support staff at the new site can be a huge benefit. They may be more willing to address your problem before the dozen others they have to deal with at any given moment. Ok. On your mark. Get ready. Go.
