Interactive Numerical Optimization Tutorial
Numerical Optimization is one of the central techniques in Machine Learning. For many problems it is hard to figure out the best solution directly, but it is relatively easy to set up a loss function that measures how good a solution is - and then minimize the parameters of that function to find the solution.

How memory safety CVEs differ between Rust and C/C++
CVE is a database used for categorizing and reporting security vulnerabilities in software. There are various kinds of vulnerabilities that can be reported. Some of them are caused simply by bugs in the program logic (like a recent CVE reported in Cargo), but some of the most nasty ones are caused by memory unsafety…

Rise and fall of JVM languages
Every now and then, there’s a post predicting the death of the Java language. The funny thing is that none of them writes about a date. But to be honest, they are all probably true. This is the fate of every language: to disappear into oblivion - or more precisely to be used less and less for new projects.

How Memory safety approaches speed up and slow down development velocity
Every March, developers worldwide each try to make a roguelike game in less than 168 hours as part of the 7DRL Challenge . Roguelike games are hard , involving procedural level generation, pathfinding, line-of-sight algorithms, and more dijkstra maps than you can imagine.

ML code generation vs. coding by hand: what we think programming will look like
Will ML code generation like GitHub Copilot replace coding by hand? We say no: developers still maintain generated code, so abstraction matters.

Upgrading from React 0.11.2 to 0.14.7 in 347 easy steps
Today I set out to the task of upgrading a set of views crafted with the React library. The upgrade was necessary because one part of a view using React stopped working in Chrome Version 48.0.2564.116 (64-bit). I don’t know why this happened, I didn’t find anything related to it and as it stands this was probably the…

Why async fn in traits are hard
After reading boat’s excellent post on asynchronous destructors , I thought it might be a good idea to write some about async fn in traits. Support for async fn in traits is probably the single most common feature request that I hear about. It’s also one of the more complex topics. So I thought it’d be nice to do a…
