Raindrop wants developers to know what else will change when they edit an agent’s prompt, swap its model, or give it a new tool. The company, which started out as a monitoring startup for agents (“Sentry for agents” was its…
Compilers, MLIR, LLVM, XLA, JAX You have no source code. You have a stripped.so file, a core dump, and an SLA to hit. The standard response is to treat the compiler as an inscrutable black box and resort to…
A label reads when you tilt it, then fails in its installed position. A higher-resolution camera still sees a bright patch across a metal part. A sample that reads reliably on the bench starts timing out inside the machine. None…
Most people don't quit calorie tracking because they don't care about their health. They quit because logging a meal feels like homework. I learned this building CalyFit, a free calorie tracker aimed at beginners and busy people — and the barcode…
Systems. The support agent uses tools (knowledge-base search, calculator, code execution, a refund tool) behind an injection detector screening tasks and tool observations against four pattern families, plus an approval gate pausing destructive tool calls. The SQL agent works over…
Ray Tian — University of Waterloo, Honours Mathematics (Co-op) I explain how the resource files of Plants vs. Zombies 2 are layered (RSB, RTON, Rijndael), build a small RTON decoder from scratch, and check the container layers of a real build. In…
Das U-Boot is a well-known bootloader which brings embedded Linux devices to life since 1999, it turns 25 this year. My today's post walks through the complete U-Boot boot process, covering everything from SoC power-on to launching the Linux initrd, along with…
std::forward is similar to std::move. It is just a static_cast to rvalue reference. But it is slightly different than std::move, std::forward is a conditional cast that only cast the type to rvalue-reference if some condition is satisify.
A question up front — I'll answer it at the end: when did you last verify that your fuzzer is executing the code you actually intended? Not "executing code at all" — everyone's coverage grows. I mean that code. If you can't…
When learning C programming, there are some fundamental concepts every beginner needs to understand before writing more complex programs. Three of these concepts are preprocessor directives, header files, and variable declarations. Although they may look simple, they play an important…
