A Web developer is someone who programs Web pages. A Web developer is more focused on the way a website works than how it looks. They typically use HTML text editors and work with databases and programming languages as well as HTML.

Web developers have the following skills:

• HTML
• Some CSS
• JavaScript and Ajax
• PHP, ASP, Java, Perl, or C++
• MySQL Database
• Project management

Companies looking for Web developers are looking for people with a strong programming skills that can build and maintain websites that function well.

Web developers won't be asked to create the look and feel of a website.

Web Developer is Used to Mean Programmer

Some people use the term Web developer to mean programmer or administrator. Web developers are sometimes asked to do all back-end work and do hardly anything in HTML.

Be sure to read the job description carefully for any job you are applying for to make sure you meet the requirements.

As webmaster, obtaining information regarding Apache optimization can be useful, especially when you want to reduce the load on your servers as well as decrease the loading time. This article delivers the discussion about optimization on an Apache server. You should remember that this guideline is exposed with an assumption you have administrative permissions on as server. 

First thing first, the primary discussion refers to ‘duplicate variables’ in PHP. Such as retrieving data from page headers, assigning it to a variable and using the variable to process information. By doing this, you can get your code cleaner look although this step can double the amount of memory PHP needed to accomplish the script.

The second stage, it is important for you to avoid using loops, especially when you create database queries. Avoid making a separate query for each row because it may cause slow scripts and unnecessary server load. Thus, you can use a loop to combine everything into a single query and perform single SQL after the loop.

The third one related to Opcode cache. It can save you a lot of time and server load. You can go for eAccelerator and xCache software for easier process. These software will cache PHP scripts and prevent the same script to be executed repeatedly for client.

There is possibility exists if you want to make your memory buffer smaller to force PHP to send data to clients more frequent through your php.ini file and go for ‘output_buffering’ setting. Moreover, optimizing limits is necessary because it means you optimizing your PHP as well. This sets the amount of memory a script can take before being killed. You have another option to set the memory limit for directories by making use .htaccess.

Next, it is true that you can make the pages to load faster and reduce server load by minimizing the number of PHP in your code. You can replace PHP code with static code if it happens you use any CMS system. The removal of unnecessary PHP will make the webpage load time to decrease.

Another important guideline suggests you to use ‘echo’ rather than ‘print’ when displaying information from PHP because ‘echo’ is proved faster. The ‘print’ is slower because it returns s success status, whereas ‘echo’ doesn’t have any return value. 

The last one is the use of MySQL. By knowing how to use PHP and MySQL, you will be go for using ‘SELECT’ habit as selecting data. So, it is vital to only select the rows you need because it results in significant performance enhancement.

Media files, data synchronization, and remote backups, oh my! Home computing has advanced to a point where it's practical to run your own home server, and we're running down the five best tools for the job.

Earlier this week we asked you to tell us what software you used to power your home servers and add that extra kick of convenience and power to your home networks. After tallying up the votes we're back to share the top five contenders for the home server championship belt. The following server implementations cover a broad spectrum of solutions ranging from install-it-and-forget-it to tinker-your-way-to-perfection and everything in between.

FreeNas

FreeNAS is by the far the most bare bones home server software in the top five. More specifically, FreeNAS is an extremely minimal distribution of FreeBSD. How minimal, you ask? You can run FreeNAS off a 32MB flash drive. Designed to be an absolutely skeletal operating system to maximize the resources devoted to storage FreeNAS is great for when you want a simple operating system that leaves every hard drive bay and disk platter wide open for file storage goodness. Despite being so slim, FreeNAS is still feature packed, including support for BitTorrent and remote web-based file management via QuiXplorer; it even serves as the perfect iTunes music server. You can boo FreeNAS off nearly any media: hard drives, optical discs, floppy disks, and flash-based media. It has support for both hardware and software based RAID, disk encryption, and management of groups and users via local authentication or Microsoft Domains. Even an old dusty Pentium III can become a headless file-serving powerhouse with the addition of a basic $20 SATA PCI card to pack it full of modern hard drives, thanks to FreeNAS's scant 96MB of RAM requirements.

Ubuntu Server Edition

Ubuntu Server Edition shares the ease of use that has catapulted its desktop-edition sibling to popularity. The automated LAMP (Linux, Apache, MySQL, and PHP) installation makes installing the core components of a robust server a walk in the park compared to manually configuring each component on your own. While configuring Ubuntu isn't going to be as easy as grabbing a pre-configured Windows Home Server off the shelf at your local Best Buy and plugging it in, there are a wealth of applications to help you integrate your Linux based home server with the rest of your network. It won't be as straight forward as using Windows Home Server or a Time Machine backup, but Ubuntu is more than powerful and capable enough to handle all your media streaming, remote back up, and file serving needs. We've covered using Ubuntu as the basis for a home media server before, so if you're considering trying it out check out how to build a Linux media server and build yourself an affordable media server to get an idea of what you're in for.

Apache

Apache is the only entry in the top five that isn't a completely stand alone server package. Apache is, however, open source and cross platform; it support a dozen operating systems; and it's the backbone of many of your fellow readers' home server operations. Because of its widespread adoption and extreme compatibility with a variety of platforms, we're including it here. No matter what operating system you throw on your home server, you're almost guaranteed that you can run Apache on it. Nearly four years ago we covered how to set up a personal web server using Apache, and it's still relevant and worth a look for getting an idea what the setup entails. While you're at it, you may also want to try setting up a home Subversion server with your Apache installation for keeping track of file revisions.

Debian

Why use Debian for a home server? There are over twenty five thousands software packages available for Debian, and the operating system supports 12 unique hardware architectures. There's a a slim-to-none chance you've got a computer that can't run it. Like Ubuntu—a Debian derivative by the way—you can configure this flexible operating system to do nearly anything you can imagine, from serving media and remote backups to running your own web server with a wiki and running your own mail server. Like other Linux distributions, Debian can be used to run a low-power and headless server when run without a GUI and using remote administration. Along with FreeNAS, Debian is a prime candidate for turning an aging computer into a quiet, tucked-in-the-basement server.

Windows Home Server

If your home is filled with Windows-based computers—which the average American home certainly is—it's tough to go wrong with Windows Home Server. It isn't free, and until recently you couldn't even buy it separately from the home servers sold by Hewlett Packard and others—but even though it has the distinction of being both the only commercial and closed-source software package on the list, that doesn't mean you should dismiss it out of hand. Windows Home Server stands definitively as the most Average Joe-friendly server implementation on the list. Not only is it the only server package you can buy pre-configured and installed in a ready to go off-the-shelf server, but Microsoft has gone out of their way to make the experience of using Windows Home Server as transparent and painless as possible for the end user. In fact, many Lifehacker readers expressed the "It just works" sentiment when logging a vote for Windows Home Server. Once you have all your computers connected to your Windows Home Server, you'll have a centralized backup location that supports up to 10 remote PCs and indexed remote file storage. Printers are shared and there is easy to use remote server access to log into your archives from anywhere in the world. Files are no longer lost in a mass of drives, add a few terabyte drives to a Windows Home Server and you'll never wonder if that movie file is on the F, G, or H drive again. Windows Home Server spans drives using Drive Extender so that files are located in a single folder namespace, sans drive divisions. The most recent update of Windows Home Server even adds an option to backup the server itself to external drives for extra data redundancy. Since the Microsoft site for Windows Home Server is heavy on promotion but low on actual screenshots, check out our screenshot tour for more.
