Is XMPP any good? Also, let's write a client in Tcl, maybe
I still have my Nokia 5800 lying around. It runs Symbian. That platform is quite different from Android. For one thing the internal storage size is 81 MB - less than what your single android app takes up, even in RAM, and it works faster than modern smartphones - e.g. the SMS app opens instantaneously. Another…

Practising Programming
When we see a world-class musician flawlessly play challenging music, it can be tempting to imagine that they were always able to do so. A moment’s thought makes it obvious that they must have had to spend huge amounts of time practising basic techniques in order to reach that level. What’s less obvious is that they…

Things I would like to see in a computer algebra system
If I were to design a computer algebra system (CAS) from scratch today, I would try to achieve the following goals. Several ideas have already been implemented in one system or another, but certainly not all at once.
