ざっくり理解するPaxos - 小野マトペの納豆ペペロンチーノ日記
ゴールデンウィーク中、Appleがオープンソースとしてリリースした分散データベース FoundationDB のドキュメントを読んでいました。なかなか面白いデータベースだと思うのでこれについては別途書きたいですが、それはそれとしてFoundationDBでは、分散環境下でACIDトランザクションを実現するために、分散合意プロトコルとして有名なPaxosを採用しているようでした。 PaxosはGoogleのChubbyやCassandraのLight Weight Transactionなどで使われていますが、僕はいまだにPaxosがどのように動作するのかあまりよく分かっていませんでした。良い機会だと思い、FoundationDBの技術を理解するためにも連休の後半でLeslie LamportによるPaxosの論文の一つ Paxos Made Simple を読み、何となくわかった気持ちにな
The Undeniable Utility Of CSS :has • Josh W. Comeau
IntroductionI don’t know if you’ve noticed, but the CSS world has been on fire recently. 🔥 Behind the scenes, all major browser vendors and the CSS specification authors have been working together to deliver tons of highly-requested CSS features. Things like container queries, native CSS nesting, relative color syntax, balanced text, and so much more. One of these new features is the :has pseudo-
Sticky Headers And Full-Height Elements: A Tricky Combination — Smashing Magazine
Sticky positioning is one of those CSS features that’s pretty delicate and can be negated by a lot of things, so here’s another one to add to your mental catalog: Sticky elements don’t play nicely if they have to coordinate with other elements to make up a combined height, like 100vh. Philip Braunen explores why this happens and presents a solution to fix it. I was recently asked by a student to h
The web's clipboard, and how it stores data of different types
The web's clipboard, and how it stores data of different types If you've been using computers for a while, you probably know that the clipboard can store multiple types of data (images, rich text content, files, and so on). As a software developer, it started frustrating me that I didn't have a good understanding of how the clipboard stores and organizes data of different types. I recently decided
Notes on structured concurrency, or: Go statement considered harmful — njs blog
fake link Every concurrency API needs a way to run code concurrently. Here's some examples of what that looks like using different APIs: go myfunc(); // Golang pthread_create(&thread_id, NULL, &myfunc); /* C with POSIX threads */ spawn(modulename, myfuncname, []) % Erlang threading.Thread(target=myfunc).start() # Python with threads asyncio.create_task(myfunc()) # Python with asyncio There are lot
Async Rust can be a pleasure to work with (without `Send + Sync + 'static`)
Async Rust can be a pleasure to work with (without `Send + Sync + 'static`) Sep 04, 2024 Async Rust is powerful. And it can be a pain to work with (and learn). If you’ve used async Rust, you’ve almost certainly run into the need to add Send + Sync + ‘static bounds to functions, wrap variables in Arcs and Mutexes, clone those Arcs all over the place, and you've inevitably hit the "future is not Sen
Beyond Ctrl-C: The dark corners of Unix signal handling :: sunshowers
In this table: SIGKILL is also known as kill -9, and it’s a special signal used to kill a process. What sets SIGKILL apart is that unlike almost all other signals, its behavior can’t be customized in any way. SIGSEGV might be familiar to you if you’ve ever encountered a core dump. Somewhat surprisingly, the behavior of SIGSEGV can be customized. For example, the Rust standard library customizes SI
Captured Custom Properties
Current music:toe — 風と記憶Current drink:Yunnan teaTable of Contents Introduction In a few of my latest experiments and articles (“Fit-to-Width Text: A New Technique” and “Querying the Color Scheme”), I used one naming pattern for registered custom properties that I think worth highlighting in a separate blog post. Registered custom properties are invaluable, as they unlock many things previously not
Changes to `impl Trait` in Rust 2024 | Rust Blog
The default way impl Trait works in return position is changing in Rust 2024. These changes are meant to simplify impl Trait to better match what people want most of the time. We're also adding a flexible syntax that gives you full control when you need it. TL;DR Starting in Rust 2024, we are changing the rules for when a generic parameter can be used in the hidden type of a return-position impl T
WebP: The WebPage compression format
September 7, 2024 Hacker News Reddit Lobsters RussianI want to provide a smooth experience to my site visitors, so I work on accessibility and ensure it works without JavaScript enabled. I care about page load time because some pages contain large illustrations, so I minify my HTML. But one thing makes turning my blog light as a feather a pain in the ass.

Build Your Own Text Editor
Build Your Own Text Editor Welcome! This is an instruction booklet that shows you how to build a text editor in C. The text editor is antirez’s kilo, with some changes. It’s about 1000 lines of C in a single file with no dependencies, and it implements all the basic features you expect in a minimal editor, as well as syntax highlighting and a search feature. This booklet walks you through building
Parsers are relative bimonads
Parsers are what now?! Even to a Haskeller —proficient in the magics of functors and monads— the term of relative monads might be foreign; let's thus motivate their existence. Recently I've been thinking about how parsing expression grammar specifies very little about how syntax errors are to be reported or aggregated. Declaration ← Function / Struct / Module Function ← "fn" Name "(" ... Struct ←
