Making Web Browsing Easy For The Tiny Screen

Post date: August 9, 2005, 19:08 Category: Network Views: 3535 Comments
Tutorial quote: An avalanche of content will soon appear in the palm of your hand.

Tiny screens are showing up everywhere in PDAs and cell phones. Many are equipped with some form of network device and a browser, so it's not hard to see what's coming down the pike.

Late model PDAs, like my HP iPAQ 3715 no longer suffer from insufficient computing power, lack of memory or having to rely on pricey external 802.11b cards. The little machine is quick to boot up and can handle many daily business functions.

Even though it runs a version of Internet Explorer, jumping onto an access point and browsing web pages is fast and useful.

In this edition, I'll share my observations on things you might consider when converting LAMP (Linux, Apache, MySQL, PHP) applications or web pages, for use on the tiny screen. I'll approach the issues from an iPAQ user perspective and focus on convenience and making the user's life easy.

Storing Files/Directories In Memory With tmpfs

Post date: December 9, 2008, 12:12 Category: Miscellaneous Views: 3690 Comments
Tutorial quote: You probably know that reading from RAM is a lot of faster than reading files from the hard drive, and reduces your disk I/O. This article shows how you can store files and directories in memory instead of on the hard drive with the help of tmpfs (a file system for creating memory devices). This is ideal for file caches and other temporary data (such as PHP's session files if you are using session.save_handler = files) because the data is lost when you power down or reboot the system.

Performance Tools for Optimizing Linux: Process-Specific CPU

Post date: June 1, 2005, 07:06 Category: Optimizing Views: 3873 Comments
Tutorial quote: The tools to analyze the performance of applications are varied and have existed in one form or another since the early days of UNIX. It is critical to understand how an application is interacting with the operating system, CPU, and memory system to understand its performance. This chapter will help you understand where the bottleneck in your system is occuring, and how to fix it.

Using MySQL to benchmark OS performance

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 4264 Comments
Tutorial quote: It seems to be an exciting time for *nix operating systems, with a number of them recently releasing new versions that bring the addition of expanded features and claims of improved performance. If you're using GNU/Linux, OpenBSD, NetBSD, FreeBSD, or Solaris as a database server, you've probably recently considered an upgrade or switch to another OS in that list due to marketing hype and hearsay. This article will show you how to benchmark operating system performance using MySQL on these OSes so you can find out for yourself if you're missing out. While this may not necessarily be indicative of overall system performance or overall database application performance, it will tell you specifically how well MySQL performs on your platform.

The following operating systems were used for the comparison testing:
- FreeBSD 4.11
- FreeBSD 5.3
- NetBSD 2.0
- Linux 2.6
- Linux 2.4
- Solaris 10 x86 (build 69)
- OpenBSD 3.6

Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn

Post date: October 10, 2007, 10:10 Category: Installing Views: 4966 Comments
Tutorial quote: Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn

This HowTo describes the implementation of Nginx with php5 support (through FastCGI). The fast-cgi process will be initiated via spawn-fcgi. Nginx is a great replacement of Apache with very low memory footprint and contrary to Lighttpd, does not suffer from memory leak over time. You can then use all the memory left to unleash the power of mysql for instance by increasing the default query cache.

Breaking the SHELL

Post date: May 29, 2005, 01:05 Category: Programming Views: 3918 Comments
Tutorial quote: Shell scripts are a part and parcel of almost all software applications running on UNIX, and the use simply spans from a trivial script, managing automatic database backup to bunch of scripts collaboratively doing complex operation on regular expressions.

Though it's a mere design decision to partition modules between scripts and programming language, but I personally feel that they sometimes come very handy saving lot of time and lines of code, when compared to implementing the same functionality in the programming language in context.And in fact with some exceptions, complexity of a shell script can scale to that of codes in C language. Add to this the power of all those numerous UNIX commands, and just think through, what can be achieved by shell scripts.
Here I will discuss few topics mainly relevant to intermediate shell programmers
