I’ve recently had reason to do a bit of work with JNI .  Throughout the course of this work I had to do quite a lot of Googling in order to figure out how to properly manage the caching of various JNI objects used by my C++ code. Some JNI objects can be safely cached and re-used at any point, while others have limited lifetimes and require special handling. Obtaining JNI objects through JNI APIs is, broadly speaking, fairly expensive, so it’s smart to persist those objects which will be re-used in multiple[...]

A Developer's journey from OO to Functional

Continuing the Advent of Code theme from the previous post. Figured since this year is going to be my year of CUDA, this would be a good opportunity to take it for a ride. A good April 1st post, but why wait? So, how can we make this even faster than the already fast imperative […]

This holiday season my brief indulgence was solving the Advent of Code puzzles. One was about the look-and-say sequence. It starts with “1” and grows as follows: 1 is read off as “one 1” or 11. 11 is read off as “two 1s” or 21. 21 is read off as “one 2, then one 1” […]
