I'm really happy to hear this. The vision for Arrow is solid, and I'm looking forward to a future where C++, Python, and other languages like Rust can interoperate more smoothly in an integrated analysis workflow. I hope Wes and U

It’s not all about compute. SIMD instructions allow you to load more bits per instruction cycle. When you are doing sequential access on a modern processor, this can make a huge difference. It allows you to use the memory bandwidth to its f

To address your question about allocations, in Rust, you always know when you are allocating on the heap vs on the stack. The way you write your code guarantees it. Stack allocations are “basically free” compared to the heap because the mem

Interesting. The fourth post from today seems very promising. It gives me increasing confidence that Rust has chosen its code abstractions very well, to know that we can provably solve this problem without heap allocations. The lifetime bin

Really cool to see this built into the editor. Getting over the hump of “well I could install this 3rd-party extension, create an account, and follow directions, or I could just walk over to my coworker’s desk for the 15th time” is probably

The post says that if a compiler can prove "that the lifetime of the coroutine is indeed strictly nested within the lifetime of the caller", it would be able to avoid heap allocations. It makes it sound like an optional optimizati

I used to be a sound engineer for live shows. I could imagine high speed cameras being used to replace instrument microphones in live performances one day, much like optical mice replaced the roller ball style. By keeping a fixed object in

In general, no, because branch predictors often ignore or override hints like this. It's hard to say without knowing this architecture specifically, of course. Keep in mind that it's possible for a branch predictor to predict with

A bug in their software would be forgivable. This article pointed out both an extremely poor design decision (lots of unnecessary code in the kernel) as well as a serious organizational problem (not doing vulnerability management). These ar

Maybe I'm just unfamiliar with some of the Postgres syntax.. but shouldn't there be a GROUP BY in the first query?

Last time I tried VMWare Fusion (<1yr ago) I was pretty disappointed with the trackpad support (I could find absolutely no way to get horizontal scrolling, for example, and vertical scrolling was extremely jarring). Maybe it doesn't

Can you link to any of this?

At first I thought this was just an awful idea, but after hearing what you're using it for I want to use it myself :P Did you look into the possibility of "adapting" something like d3 to draw on the terminal? Or does it just
