In the last days we improved platform-support of PyPy's Python interpreter. Jean-Paul Calderone has been tirelessly working for some ti...

Today I saw the keyboard heatmap generator on the Blended Technologies blog. I threw all the PyPy code at it to see whether the heatmap lo...

(yes, C as in language, not c as in speed of light). I looked recently at the great computer language shootout, for some benchmarks and to m...

After having spent the last few days on understanding PyPy's JIT, today I went back hacking the clr module . As a result, it is now po...

The next PyPy sprint will be held in Leysin, Switzerland, for the fifth time. The overall idea of the sprint is to continue working on maki...

Georg Brandl has put up the slides of the PyPy talk he gave at the Python User Group Munich. The slides are in German.

A few days ago, Armin discovered Gnuplot . He wrote a script that turns the results of the nightly benchmark runs into plots (lower is alw...

Old-style classes have so far been a bit neglected by PyPy's Python interpreter. By default, PyPy makes all classes new-style and you ha...

Recently I've been doing a lot of profiling on the PyPy executables to find speed bottlenecks. Valgrind (the original page seems to be...

Tomorrow evening there will be an introductory talk about PyPy at the Python User Group Munich . The talk will be given by CPython and PyPy...

In the latest bunch of tasks that Titus released on Friday for the Google Highly Open Participation Contest there are several that are rela...

Of course being "faster than c" means being faster than light. What did you think it means? :-)

It seems that we can do better! Armin fixed a bug in our generational garbage collector, which caused variable sized objects (e.g. arrays) t...
