I’ve recently found the script http://www.artypapers.com/csshelppile/pcdtr/ that allows you to use your own font to write headers (like my articles headers) and is then converted into an image using GD and PHP power. It’s pretty good if you want to use special fonts that no one has on his computer.
I’d only suggest you a small fix (if it’s not working fine the first time):
//Define the GD environment variable
putenv('GDFONTPATH=' . realpath('.'));
In image.php, you should put this right after
Additional documentation on PHP’s image handling capabilities can

*/
Really useful for someone who’s trying to get the script to run but it simply won’t (it gives a “Error: The server could not create this heading image.” message if you don’t have this putenv line)
The only thing I’m looking up to is to make the possibility to use + without using the %2B because it mess up my titles

Almost 2 months after the 10 000 pages views breakthrought, Ma Chienne de vie (excitris.com) has already received his additional 10 000 pages views.
I’ve just began to post more often since my semester is almost over and I have a lot to talk about.
I’ve also changed my approach a bit. I was before used to post digg interesting articles but they aren’t that good anymore so I’ve started to write them up myself. There are many interesting things in science that can be explained and since I don’t have a big expertise (well, 4 poor years so far) what you’ll get should be comprehensible for almost anyone who had at least one year of chemistry :).

Translation:
refroidissement du liquide = liquid cooling
surfusion = supercooling
solidification = solidification
refroidissement du solide = solid cooling
température = temperature
temps = time
A liquid below its melting point will crystallize in the presence of a seed crystal or nucleus around which a crystal structure can form. However, lacking any such nucleus, the liquid phase can be maintained all the way down to the temperature at which crystal homogeneous nucleation occurs. The homogeneous nucleation can occur above the glass transition where the system is an amorphous — that is, non-crystalline — solid.
This technique is also used for heat pad (containing sodium acetate (
, also used as food additive)). Since sodium acetate can be used to produce similar effect, we’ll attempt to create a similar product by mixing vinegar with baking soda.
Now, here’s the fun part: The making of (sodium acetate)
Vinegar is acetic acid:
Baking soda is sodium bicarbonate:
Mixing the two is simply and acid base reaction.
That last product is carbonic acid which quickly decomposes into carbon dioxide and water:
The CO2 is what you see foaming and bubbling in this reaction.
To collect the , heat the solution so the water can evaporate.

See it on Wikipedia
