This essay was written with Barath Raghavan, and originally appeared in The Guardian . Major benchmarks measure what AI can do. None measure whether it does what you mean: the distance between what you ask an AI to do and the unspoken assumptions about how you want the AI to do it. We propose a new metric: the Genie coefficient. There’s often a gap between one person’s request and another’s understanding. Most of the time, we bridge it using general knowledge. For example, if you ask a friend to get you coffee, they’ll pour a cup from the pot or buy one from a coffee shop. They won’t bring you a bag of raw beans or snatch a cup from a stranger and hand it to you. You never specified any of this. You never had to...

The TK705STi’s highly responsive, low-latency performance makes gameplay ultra-realistic. For movies and TV? It’s a purely average home projector.

Never mind the “heat death of the universe.” Entropy is just a bridge between two levels of reality.

Airbus selected Scaleway as its sovereign cloud provider after a tender that scored protection against non-European extraterritorial legislation alongside technical capability. Airbus frames it as complementing multi-cloud, not exiting AWS. Practitioners note the pattern is spreading past hyperscalers to small US SaaS vendors, and that sovereignty claims still require verifiable controls. By Steef-Jan Wiggers

This isn't really a typical Ask HN, but since my LinkedIn network doesn't get me there, I thought I'd give HN a shot! Paddle, the merchant of record, used to have quite excellent support (widget in their dashboard) which then turned into workable support by e-mail. Now they have added a layer of AI automation whereby any support e-mail receives an automated AI reply to which you have to reply to escalate to a human. Unfortunately that loop is broken. I never get a human into the loop at all (the

From musical instruments and games to play pieces that encourage balance and dexterity, these toys will engage your child’s mind and body.

Hi HN, Gabriel here. This is a standalone binaural beat generator, combined with a two-deck local audio player built with the Web Audio API. It includes ten harmonic carrier pairs, seven brainwave-state presets, per-harmonic mixing (so the binaural tones aren't out-of-tune with the music), adjustable beat and carrier frequencies, two oscillator shapes, offline key/BPM analysis, automatic carrier matching, adaptive impulse noise, playlist support, and output recording. The main problem I've had w

Analysis of satellite images of Myanmar shows dozens of alleged scam compounds have appeared in recent months, despite a purported crackdown on the criminal organizations.

“I think it should stand for artificial idiot,” one 9-year-old says. Here’s why kids of all ages are calling AI “disgusting” and “creepy.”

Ich habe einen echten Speedtest in Vanilla JS gebaut (mit Cloudflare API) Kein npm install. Kein React. Kein 200-MB-node_modules-Ordner. Nur HTML, CSS und ~250 Zeilen JavaScript, die deine echte Internetgeschwindigkeit messen. 👉 Live-Demo: dsl.nevik.de/speedtest Warum noch ein Speedtest? Es gibt Speedtest.net, FAST.com und dutzende andere. Warum also selbst bauen? Drei Gründe: Transparenz: Ich wollte genau verstehen, was gemessen wird – und was nicht. Größe: Die meisten kommerziellen Speedtests laden mehrere MB an Tracking-Scripts. Meiner ist eine einzige HTML-Datei mit eingebettetem JS. Kontrolle: Ich kann das Ergebnis direkt gegen den gebuchten Tarif des Nutzers bewerten und eine fundierte Empfehlung geben. Das Ergebnis ist ein Speedtest, der in unter 50 KB ausgeliefert wird, auf jedem Gerät läuft und echte Messwerte liefert – keine Schätzwerte. Die Architektur: Drei Phasen, drei Messungen Ein guter Speedtest misst drei Dinge: Ping (Latenz): Wie schnell kommt ein Datenpaket hin und zurück? Download: Wie schnell kommen Daten bei dir an? Upload: Wie schnell kommen Daten von dir raus? Für alle drei nutze ich die öffentliche Cloudflare-Speedtest-API , die unter speed.cloudflare.com läuft. Cloudflare betreibt eines der größten Edge-Netzwerke der Welt, hat Server in praktisch jedem Land und – ganz wichtig – erlaubt CORS für diese Endpunkte, sodass wir direkt aus dem Browser heraus messen können. Die zwei Endpunkte, die alles tragen: const CF_DOWN = ' https://speed.cloudflare.com/__down?bytes= ' ; const CF_UP = ' https://speed.cloudflare.com/__up ' ; __down?bytes=N liefert exakt N Bytes zurück. __up nimmt einen POST-Body beliebiger Größe entgegen. Das war's. Kein API-Key, keine Rate-Limits, die für unsere Zwecke relevant wären, keine Kosten. Phase 1: Ping messen (ohne WebSocket) Klassische Speedtests nutzen für den Ping oft WebSockets oder RTCPeerConnection -Tricks. Das ist komplex und fehleranfällig. Mein Ansatz: Wir laden einfach einen winzigen Datenblock (1 KB) fünfma

Building an operating system is a project I have had my eyes set on ever since I discovered free will in the realm of programming. Years ago, I did a reasonable amount of research, paying extra attention to the subject during my computer science degree and I was able to understand Operating System Theory and how it works from first principles but I never really got around to building one. I had only flimsy reasons for not embarking on it like "why build one when there are tons of working ones out there? The theoretical knowledge is enough" . More recently, I am ignoring the need to not re-invent the wheel for the joy of programming. So if you are interested in also rebuilding stuff because you can, join me on this series as I document how I am going to be building kluster. kluster is in its infancy and the direction is not clear but the one certain thing is that I will be building it entirely in Rust, save some assembly instructions and a linker script and I will be explaining every single line of code along the way. It will also be designed to target the raspberrypi 4 & 5, on qemu and on real hardware respectively. This is an opportunity for anyone who wants to see how Rust works at the lowest of levels to hop on and join the ride. Note that this series will be your biggest lesson on delayed gratification because we will write a lot of code before we even get to see anything meaningful on screen but I will foreshadow what you can get by the end of part 3 if you are patient enough: {{ image(src="/images/os-part3-result.png", alt="Part 3 Results OS Dev") }} You can also clone the source code for part 1 from Github and follow along. Project Setup First things first, let us setup the foundation of the project. I'll be straight with you, I love Rust and I enjoy using the Rust ecosystem in its entirety so I will stay true to that and use it as obsessively as any true Rustacean; I won't hold back. Without doubt, all the dependencies we need are freely available as long as

I just wanted to open a CSV file quickly. Instead, I got: Slow spreadsheet apps Online tools that upload my data Way too much friction So I defined a simple goal: Fast and frictionless Fully local (no uploads) Spreadsheet-like experience That’s what I built. What you can do with it Open CSV files instantly (drag & drop, no setup) Search and filter large datasets in seconds Edit data like a spreadsheet Export exactly what you see Why this matters Everything happens locally in your browser: Your data never leaves your device No account required No tracking, no storage Built with client-side JavaScript — no backend involved. Just open, edit, and export. How it works Built with client-side JavaScript — no backend involved. Spreadsheet-Like Editing Click a cell to select it, then press Enter or double-click to start editing. Press Enter again to save the value and move to the cell below. Use Option + Enter on macOS or Alt + Enter on Windows to insert a line break. You can also drag the small fill handle to copy a value across multiple cells. Export the Current View The exported CSV reflects the current table state, including: Search results Sorting order Visible columns Saved cell edits Try it yourself Open a CSV file, edit a few cells, and export it — all without uploading anything. 👉 https://csv-open.github.io/ No signup. No upload. Just works. Handles CSV files up to 25MB Supports multiple languages
