XAMPP is The Best Choice for Programmers

XAMPP is an open source suit of Apache, MySQL, PHP/Perl. To many people, installing Apache, MySQL and PHP is difficult. XAMPP integrates them into one package. Moreover, it can run on many operating systems, such as Linux, Windows, Mac OS X and Solaris. With XAMPP, you don't need to edit any configuration file, just unpacking it, even no need to install, you can run your Apache web server with PHP and MySQL support.

Why did I say the XAMPP is appropriate for Programmers? Here are some reasons. First, XAMPP can run on many platforms, you needn't change your program or configuration files if you want to change the operating system. Second, the default configuration of XAMPP is convenient for debug program. So it is not appropriate for the final products. Third, XAMPP provides some add-ons to extend its function. Now you can integrate Perl and Tomcat into XAMPP. Besides, XAMPP contains much PHP extensions, for example, libjpeg, libpng, gdbm, zlib, expat, Sablotron, libxml, etc.

The current version of XAMPP is 1.6.6a. The Windows distribution contains:

• Apache HTTPD 2.2.8 + Openssl 0.9.8g
• MySQL 5.0.51a
• PHP 5.2.5
• PHP 4.4.8
• phpMyAdmin 2.11.4
• FileZilla FTP Server 0.9.25
• Mercury Mail Transport System 4.52

Update: I received the comments. I agree with them, too. I think a good PHP programmer should know how to configure Apache, PHP and MySQL, etc. I think XAMPP is the best because it makes the work very easy. So it can save much time. Certainly, unstanding how they work is necessary for a good programmer.

Get Traffic to My Blog

Traffic is the life of a website or a blog. I have been thinking of how to get more traffic to my blog these days. I don't like many people's advice, such as submitting my blog to many directory sites or sending lots of links to forums and so on. I'm not good at it. Since I like programming and I am good at web programming or software. Why could I use my advantages to reach the goal? Just now I found an e-book called 77 Ways to Get Traffic. I think some ideas are so good.

• Join Wikipedia. Wikipedia is a very successful website and it has much traffic. Especially, anyone can edit it. Althought Wikipedia don't allow anyone to submit spam likes. Fortunately my blog and articles are related to some wikipedia items, I can add the links into the "external links" section. But be careful, don't add spam links.
• Develop some software. I can make some shareware and freeware and I can add my site link to the software. I believe, by this way, more and more people will know me.
• Make some playful plugins or gadgets. This method is similar to the above one. But plugins or gadgets are much easier to develop. For example, I can make some WordPress plugins and Google gadgets. I think this is a wonderful thing because I like programming and the more people use my software, the more I am excited.
• Contribute to some professional websites. Many technology websites accept users' contribution, for example, CodeGuru and CodeProject. I think it is acceptable that put my website's link in the end of my article.
• Submit some posts to the shareing website, such as Digg or Del.icio.us. I have used it for nearly a month. But unfortunately, the effect doesn't seem good. I think it is more suitable for the websites who have much traffic already.

Certainly, the most is the contents. If you want to build a meaningful website, original and useful contents are most important. Don't think about "garbage sites", whose all contents are copied from other sites. I hate them and I think Google hates them, too.

Inserting Math Formula

Although there has been a markup language for mathematics called MathML, it is not convenient because it needs some browser plugins to display math formula, for example, MathPlayer. Up to now, the best way to insert math formula into web pages is converting them into images.

But how to describe a math formula with pure text? The answer is TeX. TeX is a publishing tool for scientist and it is developed by Donald E. Knuth. To use it, you must learn some things about TeX. For example, the square root of 2 can be written as '\sqrt{2}'.

MimeTeX and MathTeX are famous for converting TeX texts into images. If you have your own server, you'd better setup it on the server, although it is a hard work. But what is you haven't your own server? Fortunately, there is a public server, forkosh, providing MimeTeX and MathTeX for free. e.g. if you want to write the squre root of 2, you need to write this HTML:<img src="http://www.forkosh.dreamhost.com/mimetex.cgi?\sqrt{2}" /> or <img src="http://www.forkosh.dreamhost.com/mathtex.cgi?\sqrt{2}" />. i.e. you need to pass TeX text as the mimetex.cgi or the mathtex.cgi's argument. If you know TeX, inserting formula is very easy.

Now let's have look. The TeX text is 'x_{1,2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}'.
