JOURNAL

Back in 2006, I posted a bouncing ball simulation I wrote for a course. As it was 2006, the post used a Java Applet. Almost two decades after I published it, people continue to find their way to that page even though the Java Applet no longer works. Tired of seeing the errors show up in my analytics, I did the trendy thing and asked AI to update the code.
I recently re-learned a thing about PostgreSQL that I had learned at least one time previously. If you create a table with a foreign key constraint that includes cascading deletes and/or updates, PostgreSQL and MySQL have differeing views on whether the indexes to support those cascading operations should be created automatically.
Recently someone shared a link to a Javascript quiz that asks various questions about Javascript's infamous quirks. One of the questions required that the reader have basic understanding of floating point rounding. This is not a problem unique to Javascript and I attempt to explain why.
How many bits are set to one in a bit string? It’s a problem that pops up in a number of areas: bitsets, cryptography, error correction, and most of all interview questions. This problem is also known by many names: hamming weight, population count, popcount, sideways sum just to name a few. I recently revisited this problem in the context of writing a simple bitset and found myself falling down a rabbit hole when I tried to answer the question: how is std::popcount implemented in C++20?
