CSS3 media queries

Alexis Wilke — Sun, 15 Jan 2012 05:26:21 +0000

CSS is improving with the introduction of CSS3.

Contrary to the previous version, CSS3 supports selections that are very advanced, offering capabilities close to what you could write in JavaScript.

Today I wanted to talk about the Media Queries because that can be used to very much optimize the list of links used to load your CSS data.

In HTML, you can use a <link ...> to add a CSS file to your page.

<link rel="stylesheet" type="text/css" href="style.css" />

In this case, the file style.css will always be loaded, whatever the media being used.

MO Regex Filter for Drupal

$5.00

One of our customers changed to a new domain name. This left his site with thousands of links pointing to his old domain name. Changing all of those links manually would have proven to be too time consuming. That's when Made to Order Software decided to create the MO Regex Filter Drupal module to answer his need. This module was then used to replace the old domain name with the new domain name automatically. Many days if not weeks of work was saved!

Pop a value or a string and jump to that frame. Numerical frame numbers start at 0 and go up to the number of frames - 1. When a string is specified, it can include a path to a sprite as in:

/Test:55

When f_play is ON (1), it wakes up that sprite (movie, thread). Otherwise, the frame is shown in stop mode (it does not go past the Show Frame tag.) This action can be used to playback a sprite from another given a set of events.

PostgreSQL and Drupal conflict

Alexis Wilke — Sat, 28 Nov 2009 12:33:57 +0000

We have been running Drupal for some time now and we have noticed that it generates a very large amount of warnings in our log files.

The warning is in link with improperly formatted strings. PostgreSQL tries to follow the SQL specification to the letter and that means you cannot use the backslash character to escape special character sequences (such as \n for a newline character.)

The assert() macro in C/C++

Alexis Wilke — Sat, 27 Oct 2007 05:06:00 +0000

This is a subject that comes back all the time in C/C++ boards.

Should you use assertions?

The answer is clearly yes. But the C/C++ assert() function is usually defined using a macro. Macros have several problems. The most common ones are: they offer no type checking, they do not warn you about weird side effects, they have a different syntax than the C/C++ language itself.

One good thing: for a fast program, the debug code used to check parameters, results, etc. is gone.
