Exercism's new test runner - review needed

by bajger＠gmail.com

Hi there! \ Iâm looking for someone, who could do review of PR that implements new test runner for Exercism project that includes Pharo track. It is nice integration of using Pharo from command line, Docker (with different build args for loading correct baseline) and testing the test suite with json output (according to Exercism specific format). \ Exercism core maintainters lack knowledge of Pharo. Your help is welcome! PR here: https://github.com/exercism/pharo-smalltalk/pull/563 Related Docker part (already reviewed): https://github.com/exercism/pharo-smalltalk-test-runner/pull/16 Cheers, David

New Memory Profiler

by Sebastian Jordan Montano

Hello, I have been working on a new Memory Profiling for profiling object allocations. The profiler has reached a first stable version and I would like to share it with you. [ https://github.com/jordanmontt/illimani-memory-profiler | https://github.com/jordanmontt/illimani-memory-profiler ] The profiler gives some statistics, cool visualizations, like a heat-map, about the allocations and memory usage. If you want to profile the memory of some applications, this tool can help you. Also, if you have some use cases or you have some feedback please let us know because we are looking to improve the tool :) Cheers, Sebastian Jordan
