A small interesting fact: one animated image in the Skype chat window (the one with tongue out) raises Skype CPU usage from 5.5 to 11% (double!).

Nothing to do about it, just an interesting fact

Creating a shortcut icon in the TYPO3 multidomain installation can be a tricky option. Modern browsers (like FireFox, for example), support a link tag that allows to place shortcut icons to pages...

Update: the stolen content is now removed from the offending site.

I was notified that a seo24.at web site republished my article about TYPO3 performance optimization as their own thus violating my copyright. Here is their copy and here is the original. Pity to see that there are still people like this one. The could have asked and got permission immediately. Now I have to ban them from republishing anything from this site... I like to share and promote the knowledge but I hate content stealing in any form.

I am working with TYPO3 since year 2003. I worked for several agencies and individuals during this time. I am one of the best TYPO3 experts. This is what people say about me, not what I say about myself (I never really wanted to become a TYPO3 expert, it just happened).

I learned a lot of things while working for many people using TYPO3. Among others, there is one most important learned thing: most people think they know the right solution and they only ask TYPO3 experts (like me) to implement that solution. Typically they say: "We want...

Gzip is a good way to make your web site faster. It may decrease the size of downlodable documents by half. This seriously speeds up the loading of the site because network delays affects the performance (and user satisfaction) most.

But there is a drawback of the gzip compression that many people do not realize.

In the early Apache 1.x days mod_gzip had a very nice feature: file cache for the compressed content. mod_deflate in Apache 2 does not have any caching for the compressed content. It means that downloading 500KB of ExtJS with...

How does the usual development of the product starts in the Open Source community? Typically there are some wishes (requirements in the best case). Next coding starts. When the code is more or less ready, development of the UI starts. The UI reflects internal technical implementation. In particular, this is how TYPO3 was built and how many TYPO3 extensions are still built today.

Recently I decided to change my development practices completely. Earlier I followed the traditional way: PHP implementation first, UI last. Now I do the opposite: UI...

One of the principles of the object–oriented programming says that the functionality should be encapsulated into a component and handled by the component. It helps to keep the functionality in one place and modify it easily or rewrite/replace it completely without affecting other parts of an application.

Since ExtJS is an object–oriented JavaScript framework, the same principle should be used there.

Recently I had to create a numerous ExtJS components for one project. There are numerous ExtJS examples on the web, which show complex...
