Has anyone had a good experience with bluesound? Sends like they offer a similar product but with less big-corporate headache. Haven’t tried them myself, though. https://www.bluesound.com/

My undergraduate advisor (David Chuss) at Villanova and some of his students recently put together a really nice visualization of the magnetic fields at the center of our galaxy. Last I talked to him about it, he said that the results were

It’s important to be able to see where the async function might pause execution. For example, if you’re holding a mutex lock, you probably want to avoid holding it “across” an await point so that it’s not locked for longer than necessary if

Also see “poptrie” [0] for an efficient way to do routing table-style lookups for CIDRs (longest prefix match). They basically use the “popcnt trick” to implement sparse arrays, use “direct indexing” for the first however many bits to reduc

My public high school offered a combined physics-math course (basically two different teachers and courses that coordinated with each other), and it was definitely an excellent way to learn calculus. We learned derivatives for mechanics aro

The thing is that most code has a straightforward, tree-like ownership model. It’s overkill to use a GC for everything. It also sometimes leads to memory bloat. What we really need is an ergonomic way to opt into different kinds of memory a

This is cool – I just heard a talk related to this subject from one of the authors, Daniel Genkin, who leads the group [0] that found this vulnerability. Seems like they're doing a lot of really interesting work. The talk I heard was s

This may be more about the indexing strategy than the hash function. Meaning: once we have the hash(es), how do we decide what index to use for the key? Open-addressing schemes like linear probing, quadratic probing, certain variants of Rob

The most expensive Unifi in-wall AP is $170. Even if you had ten of them, that’s only $1700. If you’re building a house, that’s not that expensive for making basic infrastructure work well.

The real solution is to plan for having a low-power access point in every room. Maybe even hidden in the ceiling of every room. Everything gets faster and more reliable when you limit crosstalk. If anything, I’d want my future home to have

Rust often has convenience methods in its standard library for things like this that are common and tend to produce bugs when re-implemented over and over, and have a reasonable way to do it without making tradeoffs that will annoy some peo

I’m starting a PhD in a related field, and it seems like the biggest reason to be excited is simulation of small and complex physics systems, e.g. molecular interactions. Breaking RSA/ECDSA is very cool, but doesn’t actually enable new

I’ve used Litmaps[0] to discover new papers in a field. They have an interesting “discover” mode where you input papers you consider to be “relevant” and they try to suggest other papers you’d think are relevant. If you subscribe to their s

@cart, what’s your primary motivation for developing a game engine? Do you eventually want to transition into building games and spend less time on the engine? Or is the engine itself the end goal? Always enjoy the Bevy progress writeups. T

I think tweets are restricted by number of extended grapheme clusters. And probably also by number of bytes.

It also seems like Clickhouse could offer runtime detection of AVX and dispatch to the optimized functions in that case.

Counterintuitively, “Cache-oblivious” algorithms typically refer to algorithms that are cache-friendly even for an unknown cache size, or for multiple levels of caches of varying (unknown) sizes. A good example is the memory hierarchy, from

Well this all looks incredibly cool, and certainly beyond my current understanding of graph and vector databases. You mentioned in the release that you wrote your own knowledge management tool. Is that published somewhere?
