fighting for TYPO free code


Take the survey

Whoami

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.

But why?

Well . . . I like code without typo's. It just runs better ;-)

Running TYPO3 on Nginx

Tue, 4 Aug 2009

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. . .

MacPorts . . . Give me back my PHP 5.2

Tue, 4 Aug 2009

A while ago I updated my Ports list and upgraded all outdated ports.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. . .

Profiling the extension manager with KCachegrind

Tue, 4 Aug 2009

Disclaimer:

This is just an example of how to produce profiler output and analyse it, not a real attempt at optimising the extension manager (though that should be done too!).

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

Fixing the KDE font sizes on OSX

Mon, 3 Aug 2009

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. . .

Installing KCachegrind on OSX

Sat, 1 Aug 2009

This article is only relevant for users of OSX. 

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. . .

Putting the ratings extension on a diet

Sun, 28 Jun 2009

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. . .

Removing the unused blurLink related javaScript

Sun, 21 Jun 2009

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.

Enable cookie-free domains in TYPO3

Tue, 16 Jun 2009

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. . .

Enable far future expires headers for static resources

Mon, 15 Jun 2009

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,. . .
