My name is Michiel Roos. I currently work for Netcreators in Holland. I like tech stuff like Linux, TYPO3, Gumstix and Roombas but I also like to dig in the dirt and try to grow veggies and other things. Some of you may know me as author of nc_staticfilecache and maintainder of the DAM project.
Well . . . I like code without typo's. It just runs better ;-)
Last week I was searching for a bit of a performance boost for my site running on a Linode package. It's pretty OK, but not 'zippy' at all. During my search I came across a lot of interesting articles about Squid, lighttpd, Varnish and Nginx. EVO techblog has an article. . .
A while ago I updated my Ports list and upgraded all outdated ports. This gave me a shiny new PHP 5.3. PHP 5.3 is nice but it has deprecated a lot of functions and changed some other functions. This is all well and good, but now it spews a torrent of 'Notices', 'Deprecated' and 'Warning' messages when running TYPO3 4.1 and TYPO3 4.2 sites.
I can still get PHP 5.3 if I install the php5-devel package. If I really want to run that I'll compile. . .

In the previous article you can read how to install KCachegrind on OSX. If you are on Ubuntu or any other flavour of Linux, chances are that
After starting KCachegrind for the first time I was shocked to see the huge ugly font it used. This font can be changed however. It took me a while to figure out where and how but here is the solution.
The base KDE configuration resides in: /opt/local/share/config. Take a look at the 'kdeglobals' file to see the kde base settings. Your local settings are stored in /Users/yourname/.kde/share/config. Open up. . .

Coming from a Gentoo world to OSX, now and then I want to install some software that is not available pre-built for OSX. I like to use more recent Apache 2 for local testing and I also like to use Gimp and InkScape, so I use MacPorts to fetch and compile all the Open. . .
Recently I started using a great tool called Google Page Speed. After inspecting some of my pages I was amazed to learn that a the 'ratings' extension uses the prototype.js file just for the XmlHttpRequest. Prototype is not. . .
Helpdesk support back in the day of the middle age with English subtitles. Original taken from the show "Øystein og jeg" on Norwegian Broadcasting (NRK)in 2001. With Øystein Backe (helper)and Rune Gokstad (desperate monk). Written by Knut Nærum.
There is ancient code in TYPO3. It lives in 'sysext/cms/tslib/class.tslib_pagegen.php'. Here is the code that is included by default when you have not disabled all default JS code by setting 'config.removeDefaultJS' to 1.
YSlow says:
When the browser requests a static image and sends cookies with the request, the server ignores the cookies. These cookies are unnecessary network traffic. To workaround this problem, make sure that static components are requested with cookie-free requests by creating a subdomain and hosting them there.
If you have your own host, you can create such a subdomain with very little effort. The only thing you. . .
Web pages are becoming increasingly complex with more scripts, style sheets, images, and Flash on them. A first-time visit to a page may require several HTTP requests to load all the components. By using Expires headers these components become cacheable, which avoids unnecessary HTTP requests on subsequent page views. Expires headers are most often associated with images, but they can and should be used on all page components including scripts,. . .
