It occurred to me that SHA-3 being a cryptographic hash, it is one of those peculiar bits of code that are fully self-testing. Any bug in a cryptographic hash will quickly cascade to a different result, no matter the bug or the input.
This means the ad-hoc-compiler-monkey can be unleashed “safely”, and can be allowed to try “improper changes.”

A new kernel for SHA-3 (Keccak) cryptographic hashing has been committed to the DWScript repository.
It is almost 3 times faster than the Pascal version, makes use of MMX asm, and involved an “ad hoc compiler”.

I am a big fan of TBCEditor by Lasse Rautiainen, in case you have not heard about it, it is fork of SynEditthat diverged very significantly and includes support for code folding, fully JSON-based syntax highlighters, minimap and many other features.
Of course a code editor is a very complex piece of software, with many opportunities for bugs to hide. I have been helping by providing some Fuzz Testing code and vectors.
I have been using the feeds aggregator BeginEnd.net as more than just a news aggregator, it is also a Canary: once a new version of DWScript passes tests, it goes live there!
Latest Canary feature is for the new FastMM4 multi-threading improvements by Primož Gabrijelčič, which can be found under the Locking Improvements branch.
As I do not have a better place to drop them, here are some musings related to the Simulation Hypothesis, though not as in The Matrix. Came about them while thinking about how a decentralized simulation (not for a world) could be run, and then one thing led to another.
