Java – Still learning to walk (or perhaps crawl)

without comments

Java is not only a language it is a whole eco system of new things to learn. The amount of time I have actually spent with the language is fairly small compared with the time I have spent learning about parts of the eco system. Things like what are manifest files, what is this WebStart thing or more to the core of things what is a jar file. Ant, JUnit are other things I have been learning about.

Maths in wordpress

without comments

I have been wanting to get math symbols into blog entries in an easy way for quite a while, preferably using Latex approach to things. MathML is just horrible to work with when it comes to editing.

In the past I have looked around and not got very far, the solutions I found seemed to require Latex to be installed on the server, something I cannot do. Well this time I found this. It calls a separate server to generate a gif representation of the Latex command and then caches it on my own server. So now I can put maths into entries without having to think about it, well except my latex skills are slightly rusty to say the least.

Here comes one from the past…
\left( \frac{-\hbar^2}{2m} \nabla^2 + V(\vec{r}) \right) \psi(\vec{r},t) = i\hbar \frac{\partial \psi}{\partial t}(\vec{r},t)
