I'm concerned by the number of times I've heard, "oh, we can do RAG with retriever X, here's the vector search query." Yes, your retriever for a RAG flow should definitely support vector search, since that will let you find documents with similar semantics to a user's query, but vector search is not enough. Your retriever should support a full hybrid search, meaning that it can perform both a vect
Biden Tells Allies He Knows He Has Only Days to Salvage Candidacy
President Biden has told key allies that he knows the coming days are crucial and understands that he may not be able to salvage his candidacy if he cannot convince voters that he is up to the job after a disastrous debate performance last week. According to two allies who have spoken with him, Mr. Biden has emphasized that he is still deeply committed to the fight for re-election but understands
How and why we built our startup around small teams
Welcome to Product for Engineers, a newsletter created by PostHog for engineers and founders who want to build successful startups. Startups ship more per person than big companies – everyone knows this. But how do you retain that advantage as you scale? Our answer is small teams – speedy, innovative, and autonomous one-pizza teams where individuals can still have an outsized impact. They enable u

A microcontroller Macintosh This all started from a conversation about the RP2040 MCU, and building a simple desktop/GUI for it. I’d made a comment along the lines of “or, just run some old OS”, and it got me thinking about the original Macintosh. The original Macintosh was released 40.5 years before this post, and is a pretty cool machine especially considering that the hardware is very simple. I
Today we’re excited to announce the release of TypeScript 5.5! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s edi

The foundation models built into Apple Intelligence have been fine-tuned for u
IntroductionOn June 27, 2024, a small number of users globally may have noticed that 1.1.1.1 was unreachable or degraded. The root cause was a mix of BGP (Border Gateway Protocol) hijacking and a route leak. Cloudflare was an early adopter of Resource Public Key Infrastructure (RPKI) for route origin validation (ROV). With RPKI, IP prefix owners can store and share ownership information securely,
A Git story: Not so fun this time | Brachiosoft Blog
Linus Torvalds once wrote in a book that he created Linux just for fun, but it ended up sparking a revolution. Git, his second major creation, also an accidental revolution. It’s now a standard tool for software engineers, but its origin story wasn’t so much fun this time, at least for Linus. Linus doesn’t scale 1998 was a big year for Linux. Major companies like Sun, IBM, and Oracle started getti
NOTE: This is based on, but completely rewritten, from a Twitter post: https://x.com/TheGingerBill/status/1802645945642799423 TL;DR It makes Go feel too “functional” rather than being an unabashed imperative language. I recently saw a post on Twitter showing the upcoming Go iterator design for Go 1.23 (August 2024). From what I can gather, many people seem to dislike the design. I wanted to give m
Competitiveness is a vice of mine. When I heard that a friend got Linux to boot off of NFS, I had to one-up her. I had to prove that I could create something harder, something better, faster, stronger. Like all good projects, this began with an Idea. My mind reached out and grabbed wispy tendrils from the æther, forcing the disparate concepts to coalesce. The Mass gained weight in my hands, and a
The last year has been a great one for WebKit. After unveiling Safari 17 beta at WWDC23, we’ve shipped six releases of Safari 17.x with a total of 200 new web technologies. And we’ve been hard at work on multiple architectural improvement projects that strengthen WebKit for the long-term. Now, we are pleased to announce WebKit for Safari 18 beta. It adds another 48 web platform features, as well a
As President Joe Biden was going over his final notes with his inner circle and getting ready to debate Donald Trump on June 27 in Atlanta, his wife slipped into a nearby meeting of the Democratic Party’s biggest donors. The Biden Victory Fund and the Democratic National Committee’s financial bigwigs had all assembled in the Ritz Carlton as part of a two-day political briefing that featured emotio
Last week, the CSS WG resolved to add an inline if() to CSS. But what does that mean, and why is it exciting? Last week, we had a CSS WG face-to-face meeting in A Coruña, Spain. There is one resolution from that meeting that I’m particularly excited about: the consensus to add an inline if() to CSS. While I was not the first to propose an inline conditional syntax, I did try and scope down the var
Some time ago, Hillel Wayne published an article titled Microfeatures I’d like to see in more languages . In this article, he described three kinds of features in programming languages: fundamental features, deeply engrained features, and nice-to-have convenience features. Hillel’s premise was that language designers tend to focus on the first two; however, because the convenience features are rel
This post could’ve been titled “Nostr vs ATProto”, but that really isn’t what I wanted to do here. While I will be comparing and contrasting them a lot, and that’s kind of even the point of writing this, I didn’t want to really pit the two against each other at all, and especially not with the title. I also want to try avoiding commenting on the differences between the communities that have formed
自宅でネットサーフィンをしているだけでも、世界観が広がっていくのを感じる。ChatGPTに「アカデミズムの評価が高い歌を教えてくれ」と質問をしたら、すぐに答えが返ってきた。 アカデミズムの評価が高い歌は、その歌詞やメロディ、テーマが深い意味を持ち、社会的、歴史的、哲学的な視点からも評価されるものが多い。以下はいくつかの例です。 アカデミズムの評価が高い歌 ボブ・ディラン（Bob Dylan）の「風に吹かれて（Blowin' in the Wind）」 この曲は公民権運動の象徴となり、ディランの歌詞は詩としても高く評価されています。彼は2016年にノーベル文学賞を受賞し、その評価をさらに高めました。 www.youtube.com ジョン・レノン（John Lennon）の「イマジン（Imagine）」 平和とユートピアを描いたこの曲は、そのメッセージ性と美しいメロディで広く認知され、社会的

Properly Testing Concurrent Data Structures Jul 5, 2024 There’s a fascinating Rust library, loom, which can be used to thoroughly test lock-free data structures. I always wanted to learn how it works. I still do! But recently I accidentally implemented a small toy which, I think, contains some of the loom’s ideas, and it seems worthwhile to write about that. The goal here isn’t to teach you what y
Are animals conscious? How new research is changing minds Charles Darwin enjoys a near god-like status among scientists for his theory of evolution. But his ideas that animals are conscious in the same way humans are have long been shunned. Until now. "There is no fundamental difference between man and animals in their ability to feel pleasure and pain, happiness, and misery," Darwin wrote. But hi
The sad state of property-based testing libraries Posted on Jul 2, 2024 Property-based testing is a rare example of academic research that has made it to the mainstream in less than 30 years. Under the slogan “don’t write tests, generate them” property-based testing has gained support from a diverse group of programming language communities. In fact, the Wikipedia page of the original property-bas

Bytecode Breakdown: Unraveling Factorio's Lua Security Flaws
Dynamic languages are safe from memory corruptions bugs, right? 29/06/2024 Research Pwn Lua Some months ago I exploited a vulnerability in the Lua implementation of Factorio that allowed a malicious server to obtain arbitrary execution on clients. As the vulnerability has been patched for months already (Factorio versions below 1.1.101 are affected), is time to share the details with the community
# Collaborative ASCII Drawing With Telnet *by [@bwasti](https://twitter.com/bwasti)* **** If the server isn't swamped, you can try it out (hold shift to erase, arrow keys to move): ``` telnet bram.town ``` If you're on a newer mac, you may need to `brew install telnet`.

I wanted to explore different ways of communicating between different processes executing on the same machine, and doing so as fast as possible. We're focussing on high speed inter-process communication (IPC), but some of these approaches can be extended across a network. We'll do this exploration in Rust. A reminder that since these are independent processes, most approaches you'd take within-pro
The CSS WG resolved to add if() to CSS, but that won’t be in browsers for a while. What are our options in the meantime? A couple days ago, I posted about the recent CSS WG resolution to add an if() function to CSS. Great as it may be, this is still a long way off, two years if everything goes super smoothly, more if not. So what can you do when you need conditionals right now? You may be pleased
999 crates of Rust on the wall
tl;dr I’ve been comparing crates on crates.io against their upstream repositories in an effect to detect (and, ultimately, help prevent) supply chain attacks like the xz backdoor1, where the code published in a package doesn’t match the code in its repository. The results of these comparisons for the most popular 9992 crates by download count are now available. These come with a bunch of caveats t

Inside a 1 dollar radar motion sensor | Maurycy's blog
I recently got some cheap RCWL-0516 microwave motion sensors, mostly because I was wondering how China managed to make a radar for under a dollar: Click for mirrored back view Getting one working was quite easy, I just connected the VIN pin to 5 volts, GND to ground, and added a 1 uF decoupling capacitor on the 3V3 pin. When someone moves within ~5 meters, the OUT pin goes up to 3 volts for 3 seco
What Are CSS Container Style Queries Good For? — Smashing Magazine
What are these CSS Container Style Queries, and why should you use them? Juan Diego Rodríguez delves deeply into style queries, and not at the syntax level, but at what exactly they are solving and what sort of use cases you would find yourselves reaching for them in your work if and when they gain browser support. We’ve relied on media queries for a long time in the responsive world of CSS but th
Product Metrics That Matter
The power of metrics entered Product Management to change it forever. Before product metrics, we were shooting blindfolded. We just understood the result of our shots at the end of the game or even the championship. Feedback and learning took too long. We were relying on business metrics. Consider revenue, for example. That’s a lagging success indicator. It might take months for a decrease in user
Large language models (LLMs), programs which use reams of available text and probability calculations in order to create seemingly-human-produced writing, have become increasingly sophisticated and convincing over the last several years, to the point where some commentators suggest that we may now be approaching the creation of artificial general intelligence (see e.g. Knight, 2023 and Sarkar, 202

How I Found A 55 Year Old Bug In The First Lunar Lander Game
Update: This kinda blew up! Featured in Hacker News, Ars Technica and PC Gamer, among others. Just months after Neil Armstrong’s historic moonwalk, Jim Storer, a Lexington High School student in Massachusetts, wrote the first Lunar Landing game. By 1973, it had become “by far and away the single most popular computer game.” A simple text game, you pilot a moon lander, aiming for a gentle touch dow
