Scilab is a wonderful piece of software to use. It’s powerful, stable, a free alternative to Matlab, and it’s cross platform – happily crunching away matrices on Windows, OS X, and Linux. However the old problem persists of MS Windows using backslashes ‘\’ when OS X, Linux, and Internet URLs use slashes ‘/’. Slashes are great as they are easier to type on a US keyboard. If you are doing any kind of file IO with Scilab you must be careful when using slashes in your code if you expect your code to go cross platform. The handy boolean MSDOS variable can be used early to prevent problems.

Debugging can sometimes be maddening. You can check and recheck your code yet it will absolutely not work as you expect. I recently hit the hidden invalid character bug. One of the dangers from copying html and pasting it as code.


The W3C CSS Validation Service solved the problem.

Copying and pasting often gives unexpected headaches. Usually it’s due to assuming that only one or two words need replacing from the copied text when in fact there are more or an incremental variable needs to be changed.

While I’d like to think copying and pasting saves time, in regards to source code and programming I think that it often enough ends being a frustrating pain and should be avoided.

When displaying links inline with text you want to balance readability and noticeability. An interesting way to do this is by giving it some padding and rounded corners.

I sometimes need to copy files to servers that only allow ftp – an unsecure file transfer method. An easy, secure and fast alternative is SCP if you can remember how to use it.

SCP in Die Hard 4.0
Plus it’s used in Die Hard 4.0 so it must be good.
