Web Hosting - Sharing A Server – Things To Think About You can often get a substantial discount off web hosting fees by sharing a server with other sites. Or, you may have multiple sites of your own on the same system. But, just as sharing a house can have benefits and drawbacks, so too with a server. The first consideration is availability. Shared servers get re-booted more often than stand alone systems. That can happen for multiple reasons. Another site's software may produce a problem or make a change that requires a re-boot. While that's less common on Unix-based systems than on Windows, it still happens. Be prepared for more scheduled and unplanned outages when you share a server. Load is the next, and more obvious, issue. A single pickup truck can only haul so much weight. If the truck is already half-loaded with someone else's rocks, it will not haul yours as easily. Most websites are fairly static. A reader hits a page, then spends some time skimming it before loading another. During that time, the server has capacity to satisfy other requests without affecting you. All the shared resources - CPU, memory, disks, network and other components - can easily handle multiple users (up to a point). But all servers have inherent capacity limitations. The component that processes software instructions (the CPU) can only do so much. Most large servers will have more than one (some as many as 16), but there are still limits to what they can do. The more requests they receive, the busier they are. At a certain point, your software request (such as accessing a website page) has to wait a bit. Memory on a server functions in a similar way. It's a shared resource on the server and there is only so much of it. As it gets used up, the system lets one process use some, then another, in turn. But sharing that resource causes delays. The more requests there are, the longer the delays. You may experience that as waiting for a page to appear in the browser or a file to download. Bottlenecks can appear in other places outside, but connected to, the server itself. Network components get shared among multiple users along with everything else. And, as with those others, the more requests there are (and the longer they tie them up) the longer the delays you notice. The only way to get an objective look at whether a server and the connected network have enough capacity is to measure and test. All systems are capable of reporting how much of what is being used. Most can compile that information into some form of statistical report. Reviewing that data allows for a rational assessment of how much capacity is being used and how much is still available. It also allows a knowledgeable person to make projections of how much more sharing is possible with what level of impact. Request that information and, if necessary, get help in interpreting it. Then you can make a cost-benefit decision based on fact.

Web Hosting - Email Issues When you build a web site, you often provide a means for users to communicate with you. One of the most common 'add-ons' to a web site is the addition of some kind of email access. Email is used to sign users up for newsletters, provide communication for administrative issues and a hundred other uses. But, as everyone sadly knows, email problems can occur. Virus infection is among the most common, though the situation is actually better today than in the past. Huge efforts, and some progress, has been made over the past 10 years to reduce the number and severity of virus attacks. Hackers haven't surrendered, far from it. But they're on the defensive like never before. Many of those viruses were (and are) spread through email, usually in the form of email attachments. That's the source of the now-common advice never to open an attachment from someone you don't know. Professionals will often extend that advice to suggest you never open an attachment that's unexpected, even if it's from someone you know. Well-meaning, but computer-challenged friends often accidentally forward virus infected emails. Spam has taken over the top spot for email annoyances. It's estimated by various different professional sources that 92-97% of all email sent today is spam. While the definition varies, spam is generally regarded as any unwanted commercial email sent by someone whom the recipient doesn't know or have a business relationship with. Spam clutters email inboxes, requires people to sift through to find valid messages, and often contains offensive messages in some form. But, it's a fact of life and isn't going away anytime soon. Even though laws are in place, thousands of spammers continue to risk fines or jail for the chance of making money from that small percentage who will open the unwanted email. Other forms of email problems are even more severe for many web site owners. When the mechanisms fail that they rely on to send and receive messages to and from their users, that's a problem. Dealing with those problems can range from sending an email or instant message to an administrator, to tracking down the right person to get your site removed from a blacklist. Email is the communications vehicle of choice for millions everyday. When the system burps, someone has to take time to do something about it. Often, that means relying on a person who is already overburdened with too many issues to resolve. So, besides pointing out some sad facts or complaining, what's the point? All of the above shows just one more area you should look at when selecting a web host or deciding whether to move to another. Just as with server or network administration, companies vary in their ability to deal with email-related issues. Some are responsive and super-competent. Others, are simply indifferent or worse. And many are in between. Email administration, like server maintenance or network management, is a professional specialty. Skill in one does not necessarily mean quality work in another. Finding a web hosting company and/or system that has few email problems, and solves them quickly when they occur, is an important task. Spend some time researching who provides superior support in email. You'll be happy you did.

ļ»æCraigslist a Great Place to Find Free Stuff ā€“ While Exercising Caution of Course Craig Newmark of San Francisco founded Craigslist in 1999. Craigslist is a web page that offers anybody to sell or by articles virtually free of charge. Some of the categories such as job ads in some of the major cities have a charge, which is the funding for all the other private, free ads on Craigslist. Currently the web page is available in approximately 450 cities all over the world. IT serves more than nine billion viewers per months and therefore gives the web page a ninth place in the rankings for most frequently used web sites in the United States. The web sites offer over thirty million new postings and classifieds each month. Categories for classifieds and advertisement range from job and housing postings over traditional buy and sell classifieds all the way to community events and personal ads. Since Craigslist offers so many different ads and classifieds each month, it is also a great place to find free stuff. Many people that are about to move or have top give up a hobby due to whatever reason often times offer things for free on this web page. Generally ads and classifieds are divided by categories and then listed on the pages depending on the proximity to a major city. Many major cities in the United States have their own Craigslist. Classifieds that are posted on a city site generally are from somewhere in the proximity of the city. Often timeā€™s sellers expect the buyer to pick up the merchandise. Therefore, it is not unusual to find car ads, fitness equipment, baby clothing and items, furniture and more on the web site. Posting is for most classifieds free and there are also no fees for anything else. In contrast to some other pages, posting a used childrenā€™s toy, a piece of furniture or similar as well as anything else is completely free. The seller has the possibility to stay anonymous till shortly before the sale, when the seller decides to hand out his or her telephone number or address for sale purposes only. Of course such classifieds and advertisements can also be cons and need to always be handled carefully. Generally a good judgment of the price and offer helps to prevent from falling for fraudulent classifieds. Even though there are measures from the creators of the website to prevent fraud such as official statements and more, there is no guaranty that a fraudulent add will be taken off in time to prevent any trouble. So whenever buying or selling on Craigslist do it with caution. Craigslist offers classifieds for anything. Community, housing, personals, jobs, for sale, services, gigs and even discussion forums are all part of the web site. On this website anybody can post anything. Therefore it might take some time to find the right ad. It might even be possible that the chosen product cannot be found. Craigslist works like an online yard sale or a flea market. Therefore finding the exact product may be hard. But sometimes getting lucky is all that it takes and then the seeker is united with the product of desire. This web page should be used and supported by anybody and everybody. Whatever there is for sale, it should be put up on Craigslist, so that other people can male good use of a product that might be a good product for someone else for a few more years. Even jobs can be found on Craigslist. In cities such as New York, this web pageā€™s jobs are one of the most important sources for job hunters and therefore are not free of charge for the employers that are posting in some of the bigger cities.
