Postgres 11 – A First Look
Postgres 11 is almost here, in fact the latest beta shipped today, and it features a lot of exciting improvements. If you want to get the full list of features it is definitely worth checking out the release notes, but for those who don’t read the release notes I put together a run down of some what I consider the…

A new fast hash table in response to Google’s new fast hash table
Hi, I wrote my new favorite hash table. This came about because last year I wrote the fastest hash table (I still make that claim) and this year one of the organizers of the C++Now conference asked…

Functional core, imperative shell (2012)
Purely functional code makes some things easier to understand: because values don't change, you can call functions and know that only their return value matters—they don't change anything outside themselves. But this makes many real-world applications difficult: how do you write to a database, or to the screen? In…

I wrote one of the fastest DataFrame libraries
At the time of writing this, the coronavirus has been in our country for a year, which means I have been sitting at home for a very long time. At the start of the pandemic, I had a few pet projects in Rust under my belt and I noticed that the “are we DataFrame yet” , wasn’t anywhere near my satisfaction. So I wondered…

LLVM: The bad parts
A few years ago, I wrote a blog post on design issues in LLVM IR . Since then, one of these issues has been fixed fully (opaque pointers migration), one has been mostly fixed (constant expression removal), and one is well on the way towards being fixed (ptradd migration).

The problem is not AI code, but not knowing about system architecture or intent
If we think writing code is dead, and AI is generating all codebases, I still think the bigger problem is people or full teams not knowing anything anymore about the system...

Async and Await in Rust: a full proposal
I’m really excited to announce the culmination of much of our work over the last four months: a pair of RFCs for supporting async & await notation in Rust. This will be very impactful for Rust in the network services space. The change is proposed as two RFCs: RFC #2394: which adds async & await notation to the…

I don’t know who the Web Audio API is designed for
WebGL is, all things considered, a pretty decent API. It’s not a great API, but that’s just because OpenGL is also not a great API. It gives you raw access to the GPU and is pretty low-level. For those intimidated by something so low-level, there are quite a few higher-level engines like three.js and Unity which are…

Non-Posix File Systems
Operating systems and file systems have traditionally been developed hand in hand. They impose mutual constraints on each other. Today we have two major leaders in file system semantics: Windows and POSIX . They are very close to each other when compared to the full set of possibilities. Interesting things happened…
