Web Hosting - Bandwidth and Server Load, What's That?
Two key performance metrics will impact every web site owner sooner or later: bandwidth and server load.
Bandwidth is the amount of network capacity available, and the term actually covers two different aspects. 'Bandwidth' can mean the measure of network capacity for web traffic back and forth at a given time. Or, it sometimes is used to mean the amount that is allowed for some interval, such as one month. Both are important.
As files are transferred, emails sent and received, and web pages accessed, network bandwidth is being used. If you want to send water through a pipe, you have to have a pipe. Those pipes can vary in size and the amount of water going through them at any time can also vary.
Total monthly bandwidth is a cap that hosting companies place on sites in order to share fairly a limited resource. Companies monitor sites in order to keep one site from accidentally or deliberately consuming all the network capacity. Similar considerations apply to instantaneous bandwidth, though companies usually have such large network 'pipes' that it's much less common for heavy use by one user to be a problem.
Server load is a more generic concept.
It often refers, in more technical discussions, solely to CPU utilization. The CPU (central processing unit) is the component in a computer that processes instructions from programs, ordering memory to be used a certain way, moving files from one place to the next and more.
Every function you perform consumes some CPU and its role is so central (hence the name) that it has come to be used as a synonym for the computer itself. People point to their case and say 'That is the CPU'. But, the computer actually has memory, disk drive(s) and several other features required in order to do its job.
Server load refers, in more general circumstances, to the amount of use of each of those other components in total.
Disk drives can be busy fetching files which they do in pieces, which are then assembled in memory and presented on the monitor, all controlled by instructions managed by the CPU.
Memory capacity is limited. It's often the case that not all programs can use as much as they need at the same time. Special operating system routines control who gets how much, when and for how long, sharing the total 'pool' among competing processes.
So, how 'loaded' the server is at any given time or over time is a matter of how heavily used any one, or all, of these components are.
Why should you care?
Because every web site owner will want to understand why a server becomes slow or unresponsive, and be able to optimize their use of it.
When you share a server with other sites, which is extremely common, the traffic other sites receive creates load on the server that can affect your site. There's a limited amount you can do to influence that situation. But if you're aware of it, you can request the company move you to a less heavily loaded server. Or, if the other site (which you generally have no visibility to) is misbehaving, it's possible to get them moved or banned.
But when you have a dedicated server, you have much more control over load issues. You can optimize your own site's HTML pages and programs, tune a database and carry out other activities that maximize throughput. Your users will see that as quicker page accesses and a more enjoyable user experience.
Software copyright sample Software Copyright Sample Builds Loyal Customer Bases When choosing software copyright sample many before focusing on one or two. It is impossible to try every piece of software that exists in the world of software today. There are so many pieces of software currently on the market and new software being created as I type this. With so many new and different, competing and interesting software programs so widely available you might find something wonderful and unique available at a wonderful price or better yet, for free in the open source arena. Open source software isn't exactly software copyright sample material. This software is occasionally used as a testing ground for unproven versions of software, for software testing, or simply to determine the demand for a particular type of software. Chances are pretty good however; that if you've ever thought, "I wish I could find a program that did (insert whatever here)" someone else has had the same thought and created a program that will do just that. Perhaps the greatest beauty of a software copyright sample is that you get a taste of what the software can do without the expense of purchasing to find out whether it is right for you or your needs. There are actually many ways that companies both for profit and open source companies allow potential customers or converts to sample their products. Linux is a great example of this. They have gone from an open source nuisance to a viable competitor to many larger software companies by providing free software or a software copyright sample to consumers in order to whet their appetites for future offerings designed with profit in mind. What has developed is a viable (and growing) source of competition for Microsoft. Many open source developers are operating very much like Linux and starting out by offering a free software copyright sample to those who will try them out and give them feedback. They use the feedback to make improvements and build better products while making a name for themselves, their customer service, and the quality of the products they build. It's a win-win situation for many consumers and businesses that are just starting out and operating on a shoestring on both the part of those that offer the software copyright sample and those that are benefiting from the sample. Other companies are not as altruistic or are not as willing to wait for the payoffs. Instead of offering a completely free software copyright sample, they will offer you a free trial to their software that will either end at the end of the trial period and require a new subscription or automatically begin charging your credit card. Both of these practices have proven themselves to be highly effective methods of winning not only new customers but also seemingly unshakeable customer loyalty on the part of those that purchase software from these developers or companies. If you do an Internet search for open source software I think you will be astounded at the quality and selection that exists. There are programs that exist to do almost anything. My favorite (I must admit) are the game, but there are also many wonderful programs that can do amazing things like track your golf score, convert currency, help you organize your kitchen more effectively, figure out how much tile you need in a room. Almost anything that needs to be done, there is a piece of software that can do it-open source. The important thing to remember is that you won't find these programs in your local software store but you may find something similar to your copyright software sample that will cost considerably more money than the finished and polished version of the software that you are able to sample free.
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 184.108.40.206. 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.
News is News All Over the World (writing newspaper articles) Writing newspaper articles is a fun and interesting line of work. Newspapers exist in big cities, small towns, within corporations and on college campuses. Newspapers are printed for special interest groups as well as for world and national news. There are free newspapers and papers that appear for sale on newsstands every day. With such a large variety of newspaper types printed, there are myriads of possible opportunities for writing newspaper articles. There are some basic rules to writing articles for any newspaper and there are also some specific aspects to know about each type. Writing Newspaper Articles In general, to write a newspaper article there are a few rules that apply across the board. First, the news has to be relevant. Because newspapers make up a genre of writing that is constantly refreshing itself, there is no room for common knowledge or historical pieces. The exception is if those kinds of writing serve to connect to a current issue or event. People who read newspapers want to know what?s happening now. For that reason, writing newspaper articles often involves relatively high pressure to get the latest news written each and every day. There are some low-pressure possibilities in writing newspaper articles though. The Infrequent Print Several newspapers are only printed weekly or even monthly. In small towns that must get their papers printed off-site, it is not feasible to create a paper each and every day. That means that there?s a week, every week, to get the news in and written. Another example of low pressure writing for newspapers is working for a free publication. Free newspapers are often geared to a special interest group. Since that group is not paying for its paper, they may only receive the interesting tidbits once a month. Writing for these kinds of newspapers becomes focused on creativity and niche writing because the current events will have already reached the audience through more frequent publications. The Daily News from Top to Bottom The most reliable and frequent publications are those of big, national newspapers. The staffs are very large and are able to print very clean copies of very full newspapers. By clean, that means without errors. Smaller papers are also printed daily, but they seem almost insignificant except to the people of the local community. They receive national news second hand and run very small staffs. Interestingly enough, none of these daily papers are really about the news. Of course that is where most of the effort lies and that is the reason that people buy the papers, but it is not the root of a newspaper. Writing newspaper articles is a job heavily dependent on the advertising industry. A newspaper will only be as large as there are ads to pay for it. Newspapers do not make their money at the newsstand. They pay the bills and the employees with money from advertisers. On Campus News Working for a university paper will not be representative in the area of newspaper advertising. While some businesses do pay for ads in university papers, the funding comes from the school. If for some reason there were no advertisers one day, the paper would still go out. University publications are much more focused on the development of the students than making a successful business. Most campus papers are free and are created by students. School is a great place to get started in writing newspaper articles. The environment is challenging, but nurturing at the same time. The deadlines and standards still exist, but the writer gets great encouragement and training through the work. After working for a college paper, it will be much easier to get a job with newspapers of the cities and towns. Writing newspaper articles can be a great job. There are so many opportunities to get into writing that it is hard to pass them up. Some jobs may be very difficult to get, but others will be steps towards increasing writing success.
