Table of Contents In the last article we lowered our custom poly dialect to standard MLIR dialects. In this article we’ll continue lowering it to LLVM IR, exporting it out of MLIR to LLVM, and then compiling to x86 machine code. The code for this article is in this pull request, and as usual the commits are organized to be read in order. Defining a Pipeline The first step in lowering to machine code is to lower to an “exit dialect.

A little warm for a fire, don’t you think?” “It’s for inspiration, not warmth.” “Well, it’ll burn better if you stop poking it.” “I’m tickling it. To amuse it. You know, Shakespeare? Oh, to amuse a fire?” “I don’t think you’re remembering that right.” “And if tickling doesn’t work, I’ll try poetry or knock-knock jokes.” […]

Writing a storage engine for Postgres: an in-memory Table Access Method

With Postgres 12 , released in 2019, it became possible to swap out Postgres's storage engine . This is a feature MySQL has supported for a long time. There are at least 8 different built-in engines you can pick from. MyRocks , MySQL on RocksDB, is another popular third-party distribution. I assume there will be a renaissance of Postgres storage engines. To date, the efforts are nascent. OrioleDB and Citus Columnar are two pr....

I had a lovely conversation with my mother this week. I can’t remember what on Earth we were blabbering on about, but as I knelt down to give one of the dogs a hug, she shrieked something unforgettable: Your hair is thinning! I couldn’t tell who was more shocked: my mum at the sight of my head, or myself. Especially when I’ve been buzzing my head for years now. It’s not like I still have the wild mop I had as a teen! Growing up, baldn....

The primary, hopefully-unintended function of a “real-name policy” is to exclude people and make people less genuine. Many aren’t at home with the name deemed by society to be “real”. There’s plural systems. And trans users who haven’t made a full break from their deadname(s) yet. And at-risk users who would be doxed by such a policy. And folks who simply feel more comfortable with online handles than meatspace names, for no special rea..

Firefox 120 appears to have regressed to its older WebKit-like blue focus outlines; it briefly had dual-color white-and-blue outlines. I’d previously advised certain sites (sites with background colors that have poor contrast against the focus-ring’s blue color) to override the default focus indicators. I planned to temper that advice since Chromium and Firefox adopted focus indicators that appeared visible on a variety of background colo....

This post compares the finite-sample Gaussian efficiency of the QAD estimator against the Rousseeuw–Croux $S_n$ and $Q_n$. Pragmastat recommends Spread — the Shamos estimator — as a robust scale estimator with a 29% breakdown point. Confidence intervals are available via SpreadBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat In this post, we discuss the finite-sample Gaussian efficiency of various robust dispersio....

Hi, Ist Scrum demokratisch? Diese Frage kommt immer wieder auf. Immer wieder bin ich in Teams in denen es auf diese Frage hinausläuft. Das Stichwort ist immer wieder “selbstorganisiertes Team” Wie weit entscheidet ein selbstorganisiertes Team? Unumschritten: Das Team organisiert sich die Arbeit selbst. Der Product Owner entscheidet welche Aufgaben in welcher Reihenfolge abgearbeitet werden. Und er ist ein Teil des..

Harold had expected the last dragon would be … larger. “Disappointing, I know.” The dragon, barely three feet long, spoken in a voice like a bamboo flute—high, thin and melancholy. “Hardly a challenge at all.

Something I’ve wondered about for a little while: why don’t more languages have a call/cc operator? Having first-class continuations in your programming language gives your programmers a powerful construct. So why do only a handful of languages have it? The short answer is: it’s tricky to implement efficiently. One way to get call/cc is to convert your code into continuation-passing style. Then, call/cc simply takes the continuation i..

So a bit of an update on what I’ve been working on. This will be adapted into release notes in a while, but I haven’t quite wrapped a bow on the change set yet. Still, it has certainly been a few weeks. Didn’t quite land how busy I’ve been until I set down to draft this post. Them’s some changes, and I’m skipping a few to keep this meandering post at a sane length.
