Making Web Browsing Easy For The Tiny Screen

Post date: August 9, 2005, 19:08 Category: Network Views: 2675 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.

Sharing photographs online

Post date: July 18, 2005, 22:07 Category: Software Views: 2535 Comments
Tutorial quote: It is so convenient to take pictures on digital cameras that (it has been argued) we are all becoming better photographers: we take more pictures and therefore are able to choose only the best for printing and sharing. It is easy to experiment, see the results quickly, and share them with friends. The Internet makes sharing photographs very simple and a lot of fun.

Mysql Cluster: Two webserver setup (three servers required for true redundancy)

Post date: July 11, 2005, 12:07 Category: Network Views: 2866 Comments
Tutorial quote: This HOWTO was designed for a classic setup of two servers behind a loadbalancer. The aim is to have true redundancy - either server can be unplugged and yet the site will remain up.

DNS name serving through NSD

Post date: July 5, 2005, 06:07 Category: Network Views: 2960 Comments
Tutorial quote: Given the sheer importance of name servers in providing Domain Name System (DNS) resolution -- a process used by every Web-facing application to translate domain names into IP addresses and vice versa -- not many people put much thought into the available software alternatives for pulling off this feat. One compelling application is NSD, an alternative to the widely deployed BIND name server.

Command your network with Kaboodle

Post date: June 28, 2005, 09:06 Category: Network Views: 2824 Comments
Tutorial quote: Quite often setting up a local network is much easier than managing it. Even technically challenged users can figure out how to connect a couple of computers and a printer. However, tasks like maintenance, troubleshooting, and remote secure connections require more than just "which-cable-goes-where" knowledge. You need something like Kaboodle, a nifty tool that can help you to manage your local network like a pro.

Kaboodle allows you to visualize your local network, control computers on it via VNC, and connect to other Kaboodle-enabled networks. Kaboodle was developed for Windows, but according to its Web site, it will happily run under Wine on Linux and FreeBSD.

Build Your Own IM Server with Jabber

Post date: June 26, 2005, 22:06 Category: Network Views: 5008 Comments
Tutorial quote: Instant messaging is a great business communications tool. For example, here at Enterprise Networking Planet the staff and writers all work in their pajamas at home, at far-flung points all over the globe. ENP's crusty editor-with-a-heart-of-gold Perry White lives in a villa in the South of France. I send in my columns from a sailboat currently anchored at Raratonga. Sure, we can exchange emails, but there are times when a live exchange is better.

Squeeze Your Gigabit NIC for Top Performance

Post date: June 25, 2005, 01:06 Category: Optimizing Views: 4086 Comments
Tutorial quote: Many new workstations and servers are coming with integrated gigabit network cards, but quite a few people soon discover that they can't transfer data much faster than they did with 100 Mb/s network cards. Multiple factors can affect your ability to transfer at higher speeds, and most of them revolve around operating system settings. In this article we will discuss the necessary steps to make your new gigabit-enabled server obtain close to gigabit speeds in Linux, FreeBSD, and Windows.

Mastering recursive programming

Post date: June 22, 2005, 09:06 Category: Programming Views: 2923 Comments
Tutorial quote: Recursion is a tool not often used by imperative language developers, because it is thought to be slow and to waste space, but as the author demonstrates, there are several techniques that can be used to minimize or eliminate these problems. He introduces the concept of recursion and tackle recursive programming patterns, examining how they can be used to write provably correct programs. Examples are in Scheme and C.

Benchmarking BSD and Linux

Post date: June 18, 2005, 22:06 Category: Benchmarks Views: 3515 Comments
Tutorial quote: These benchmarks are the result of my scalable network programming research. My interest in this area is to see how scalable and fast network applications can be on standard PC hardware.

I have done most of my research on Linux 2.4, 2.5 and 2.6 kernels using a home-grown distribution I affectionately call "Leanux". I have experimented with several APIs and methods to try and get the most scalability and performance out of a web server. The ultimate goal, however, is to demonstrate scalability by surviving a Slashdotting.
