MoonBit: A Prototype Ideal for the WebAssembly Era

Recently, I came across a language called MoonBit, and the more I looked into it, the more I liked it, so I'd like to introduce it.

Numba Ball Tree (ParallelAccelerator)

This is a modified gist of Jake Vanderplas wonderful Numba Ball Tree code from the following gist. This gist basically adds the 'nopython' parameter in the jit decorators from the original gist and parallelizes the nearest neighbor query for each of the points.

Timings

With some of the new advances in numba and the modifications

After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."

Database files have to be updated before starting the server, here are the steps that had to be followed:

# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default
brew unlink postgresql
brew install [email protected]
brew unlink [email protected]
brew link postgresql

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb
