305. Slaughtering Competition Problems with Quantifier Elimination
Anytime I see questions on mse that ask something “simple”, I feel a powerful urge to chime in with “a computer can do this for you!”. Obviously if you’re a researching mathematician you shouldn’t waste your time with something a computer can do for you, but when you’re still learning techniques (or, as is frequently the case on mse, solving homework problems), it’s not a particularly useful comment (so I usually abstain). The urge is particularly powerful when it comes to the contrived inequalities that show up in a lot of competition math, and today I saw a question that really made me want to say something about this! I still feel like it would be a bit inappropriate for mse, but thankfully I have a blog where I can talk about whatever I please :P So today, let’s see how to hit these problems with the proverbial nuke that is quantifier elimination!

315. Unity's Mono problem: Why your C# code runs slower than it should
Execution of C# code in Unity’s Mono runtime is slow by today’s standards, much slower than you might expect! Our game runs 2-3x faster on modern .NET compared to Unity’s Mono, and in a few small benchmarks I measured speedups of up to 15x. I’ve spent some time investigating what’s going on and in this article I will present my findings and why everyone should want Unity’s .NET modernization to become production-ready as soon as possible.
