After nearly a decade of building embedded systems in C, C++, and Rust, I’ve somehow ended up writing Haskell for a living. If you’d asked me about functional programming a few years ago, I would have told you it was self-indulgent academic baloney—and then I stumbled into people using it for real-time systems where microseconds can mean literal life or death. I’m too old to try to convince people what tools they should use, but Haskell has some features that might interest anyone who cares abo

A customer asked for help with a longstanding but low-frequency hang that they have never been able to figure out. From what they could tell, their UI thread was calling into the kernel, and the call simply hung for no apparent reason. Unfortunately, the kernel dump couldn’t show a stack from user mode because the stack had been paged out. (Which makes sense, because a hung thread isn’t using its stack, so once the system is under some memory pressure, that stack gets paged out.) 0: kd> !thread

Summary Introduce scoped values, which enable a method to share immutable data both with its callees within a thread, and with child threads. Scoped values are easier to reason about than thread-local variables. They also have lower space and time costs, especially when used together with virtual threads (JEP 444) and structured concurrency (JEP 505). History The scoped values API was proposed for incubation by JEP 429 (JDK 20), proposed for preview by JEP 446 (JDK 21), and subsequently impro

Modern GPUs often make a difficult tradeoff between occupancy (active thread count) and register count available to each thread. Higher occupancy provides more thread level parallelism to hide latency with, just as more SMT threads help hide latency on a CPU. But while a CPU can use all of its SMT threads regardless of what code it's running, the same doesn't apply to GPUs. GPU ISAs offer a large number of very wide vector registers. Storing all registers for all thread slots would be impractica

At some point during the ’90s, the trend of marketing high-thread-count bedsheets as a higher-quality option took off. It's easy to see why you could fall for it: Higher-thread-count sheets often feel soft and silky, with a nice weight to them thanks to all the piled-on threads. More fabric must be better and last longer, right? But while thread count does affect the density and feel of that fabric, it doesn't necessarily make it a great bedsheet, or a longer-lasting one. Part of that is the he
