Reddit is back online after outage

engadget.com Unknown 2025-07-23 13:43:27

If you were having trouble viewing Reddit today, you weren't alone. Downdetector showed a spike in outages and problems at the site. Reddit acknowledged the problem on Wednesday. At 12:38PM ET, it said the situation had been resolved. Reddit told Engadget that an update was the culprit. "An update we made caused some instability," a company spokesperson said. "We reverted and are seeing Reddit ramp back up." If you tried to visit Reddit this morning, you likely saw a message reading, "Server e

AI coding tools are shifting to a surprising place: The terminal

techcrunch.com Russell Brandom 2025-07-24 15:30:00

For years, code-editing tools like Cursor, Windsurf, and GitHub’s Copilot have been the standard for AI-powered software development. But as agentic AI grows more powerful and vibe coding takes off, a subtle shift has changed how AI systems are interacting with software. Instead of working on code, they’re increasingly interacting directly with the shell of whatever system they’re installed in.

Hannah Cairo: 17-year-old teen refutes a math conjecture proposed 40 years ago

news.ycombinator.com Ágata A. Timón 2025-08-09 04:15:51

Hannah Cairo was stuck on a math problem. All she could think about during those weeks was a new approach. “After months of trying to prove the result, I managed to understand why it was so difficult. I realized that if I used that information correctly, I might be able to refute the claim. Finally, after several failed attempts, I found a way to construct a counterexample [a case that does not satisfy the studied property and therefore proves it is not universally true].” Ciaro says it required

Abstraction boundaries are optimization boundaries

news.ycombinator.com Unknown 2025-08-15 22:12:10

Abstraction boundaries are optimization boundaries The N+1 query problem occurs when your application code sends one SQL query per element in a collection. The N queries are redundant; since all of the data is in the database already, a single query should be enough. This problem is usually caused by a leaky abstraction; the ORM, or whatever database abstraction you are using, can’t anticipate that it would need to send N queries, so it can’t automatically optimize this down to a single query.

New proof dramatically compresses space needed for computation

news.ycombinator.com Max Springer 2025-08-17 14:59:28

Once upon a time computers filled entire rooms, reading numbers from spinning tapes and churning them through wires to do chains of basic arithmetic. Today they slip into our pockets, performing in a tiny fraction of a second what used to take hours. But even as chips shrink and gain speed, theorists are flipping the question from how much computation space we can pack into a machine to how little is enough to get the job done.

A brief history of hardware epidemics

news.ycombinator.com Alan B 2025-08-25 23:18:39

Living creatures aren’t the only things to be ravaged by epidemics. Computers, even Macs, can die prematurely when there are widespread manufacturing failures. I’d like to unearth a couple of mass graves from the past that have surely contributed to landfill around the world: capacitor plague and lead-free solder, and a recent problem with butterflies. Capacitor plague 1999-2007 Capacitors or ‘caps’ have a chequered history. Acting as temporary stores of electric charge, they’re used extensive

Solving LinkedIn Queens Using Haskell

June 24, 2025 · Agnishom Chattopadhyay [Thanks to James Haydon for his suggestions on improving the post and the code quality] On LinkedIn, you can play a variant of the N-Queens problem. A community version of the game (rather, puzzle) can be found here. Recently, we saw it solved using SAT solvers, using SMT Solvers, using APL and MiniZinc. Today, I will try solving it using Haskell, a slightly more conventional language. The Puzzle You are given a N-colored square-shaped board of size N.

Libraries are under-used. LLMs make this problem worse

news.ycombinator.com Unknown 2025-09-01 09:18:42

Libraries are under-used. LLMs make this problem worse. Libraries are under-used. Why? Briefly: Writing code is more fun than reading documentation. Dunning-Kruger effect leads us to understimate the complexity of the problem solved by the library we're considering. Perverse incentives: libraries compete with big internal engineering projects that look good in a promo packet. LLMs make this problem worse. Why?

Seven replies to the viral Apple reasoning paper and why they fall short

news.ycombinator.com Gary Marcus 2025-09-12 04:52:38

The Apple paper on limitations in the “reasoning” of Large Reasoning Models, which raised challenges for the latest scaling hypothesis, has clearly touched a nerve. Tons of media outlets covered it; huge numbers of people on social media are discussing. My own post here laying out the Apple paper in historical and scientific context was so popular that well over 150,000 people read it, biggest in this newsletter’s history.

Reflections on Sudoku, or the Impossibility of Systematizing Thought

news.ycombinator.com Unknown 2025-09-13 10:54:00

I reflect on the Entscheidungsproblem how it relates to Sudoku solvers. It's a little weird.. The other day, to no one's surprise, I was fumbling over a programming problem. This wasn't anything satisfyingly algorithmic, but more the thing where you're evaluating a million questions on "how should I structure this system?". While I'm no design purist, I like to at least make an attempt at sketching out the problem space and think through options before I just start coding something. My rule of

Here's how I finally cracked a tricky Linux problem with this AI terminal app

zdnet.com Jack Wallen 2025-09-16 22:57:00

Warp is scary good at fixing problems. Screenshot by Jack Wallen/ZDNET I've been using Linux for a very, very long time, and it's rare that I encounter an issue I cannot resolve. However, a few weeks ago, such a problem occurred. The issue was caused by an installed application upgrade that required a dependency that the apt package manager couldn't solve. This meant I couldn't update or upgrade the system, and that, my friends, is a big problem. I tried to resolve the issue. I even attempted

Switch 2 Battery Percentage Acting Weird? Try This Hidden Fix

It's been almost a week since the launch of the Nintendo Switch 2, which broke records for a console release by selling more than 3.5 million units in its first four days. However, there is a bit of an issue with the system's battery indicator, which may cause owners some frustration. Switch 2 owners noticed that, even though the system's battery said it was at 0%, the console was still playable for hours. Nintendo has since confirmed that this is an issue, although it appears to be a problem w

AI cracks superbug problem in two days that took scientists years

AI cracks superbug problem in two days that took scientists years Cases of tuberculosis (pictured) have increased in the UK and worldwide as the disease increases its resistance to antibiotics A complex problem that took microbiologists a decade to get to the bottom of has been solved in just two days by a new artificial intelligence (AI) tool. Professor José R Penadés and his team at Imperial College London had spent years working out and proving why some superbugs are immune to antibiotics.
