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.

A Writer’s Best Friend: The Job of an Editor (editing) Are you irritated by typos and spelling errors in professional documents? Are you able to help your friends make their writing error free? You may be a good candidate for editing. The world is incredibly dependent on writers and the craft of writing. It is how people communicate with each other most often. As the internet writing forms do not require people to hold to correct grammar, spelling or professional style, most writers are losing their capabilities to complete a professional document or book without help. Writers have always needed the help of editors. Even when there was strict attention to correct writing, editors could come and catch missed errors as well as mistakes in content. Editors are still needed today. Read on to find out more about what can be involved in a life of editing. Who are the Editors? Editors are those people with the ability to read a document and guide a writer to make it the best piece of writing that it can be. Editors work in newspapers, and magazines. They also work for publishing companies and in student resource centers. Editors generally have some education that leads them to the ability to help writers. They probably have a degree in language as well as training with style manuals. What is the Job? An editing job involves taking a piece of writing and conforming it to some particular set of standards. Style manuals are often the standard used. Different publications will choose a style and then ask the editors to make all of the writing that comes out to be consistent to that style. Editing is not only concerned with objective corrections like spelling and grammar though. An editor must also read for clarity, consistency and voice. If a writer claims one thing in one point of their piece and seems to contradict that point in another part, it is the editor’s job to catch the mistake and work with the writer to fix the inconsistency. If the writer is speaking authoritatively in the beginning of a piece and then becomes apologetic later, it is the editor’s job to make the tone match. Editors help with sentence construction, word choice and content order. How to Find Editing Jobs If any of the above job description sounds interesting and even exciting to you, you just may have found your ideal job calling. Before you start looking for editing jobs, you should test your skills. There are editing tests online. Feel free to use a style manual as well as your intuition as you correct the sentences and word choice in the different test questions. If you do not pass the test, you should probably spend a little more time reading a style manual and a basic grammar guide. Once you can ace an editing test, it’s time to look for a job. Be sure to include any experience you may have had. Include any editing of any kind you have ever done. Peer editing in school is appropriate experience to mention. Also be sure to list any style you are able to edit to. Examples are AP, Chicago, MLA, and so on. If you get an interview, be prepared to take another editing test, with the help of your manual. The test will likely be timed. Editing is a rewarding career. It involves helping writers to do their very best writing geared to their particular audience. While it can be stressful because of deadlines and workload, at the end of the day you will know that you have made the world of the written word a little cleaner and much more effective. Editors are an essential part of making the written word what it is today.

Web Hosting - Look Before You Leap Companies that offer Internet-connected servers that provide space and bandwidth for a domain, for one or more web sites, are called Web Hosts. Large companies have private networks that allow them to host domains on their own equipment and IP address range. But for the majority of those who want an Internet presence, a 'rented' web host is a necessity. There are a wide variety of hosting plans available. Some are free, others charge up to a $100 or more per month. Some provide nothing but a tiny amount of disk space and minimal network bandwidth. The web site owner is on his or her own for any thing else. Others offer a range of services, including server and email administration, backups, web site design assistance, troubleshooting and many others. In the world of web hosting, you may often find yourself sharing a server with anywhere from one to a thousand or more other web sites. That allows the web hosting company to keep equipment and staff expenses lower. Many web sites are simple and low-volume enough that the arrangement works fine. When you or one or more of the others grow, it may be helpful to consider a dedicated server. A dedicated server, as the name suggests, hosts only your domain. You can put one web site on it, or as many as you wish. You control the access. You may also, as an option, take over much of the server administration yourself. That may save you money on support costs, but cost you considerable time. If you don't have the expertise, you can end up costing yourself much more than you save. In order to carry out those administrative functions yourself, even if you hire help, it's desirable to have some technical knowledge under your belt. Some of that knowledge will be useful, even for day-to-day tasks apart from dealing with emergencies. FTP, email administration, backup methods and other technical areas are among the more common areas you'll need to be at least somewhat familiar with. When your web site grows to a certain size and level of complexity, you'll begin to find it worthwhile to look at implementing a database. But that brings with it a still higher level of ability, both technical and logistical or creative. Implementing a database can be relatively simple. Designing one that provides what you want, with decent performance and maintenance that doesn't become a nightmare, will take some careful thought. Not everyone has the temperament for that type of work, especially those who prefer graphical design, content creation or development, and the many other web site tasks that are part of every implementation. There are other, more low level administrative matters. Managing disk space, maintaining domain names, dealing with registration and changes, and a number of other 'utilitarian' tasks are also not everyone's cup of tea. Some understanding of how DNS works, as well as the design of the Internet itself, are helpful. That provides a good context for understanding the role of some of those tasks. When you begin to seek out a web host to implement a web site, consider all these factors and look in the mirror. What kind of web hosting you should pursue is determined by a combination of who you are and what's being offered. Look before you leap.
