I let LLMs write an Elixir NIF in C; it mostly worked

news.ycombinator.com Isaak Tsalicoglou 2025-11-19 17:02:25

This post documents how I built a cross-platform Elixir NIF in C to get on-demand up-to-date disk-usage stats without relying on os_mon and its disksup service. I had Grok 3 generate the initial C code and Makefile, then iterated through multiple code reviews by Gemini 2.5 Flash and GPT-5 to make it work on Linux, macOS, Windows, and the BSDs (except DragonFlyBSD). Along the way, I ran into typical LLM hiccups that speak volumes about the breathless hyperbole often peddled by LLM vendors, comput

Open-Sourced AI Models May Be More Costly in the Long Run, Study Finds

gizmodo.com Bruce Gil 2025-11-19 17:00:24

As more businesses adopt AI, picking which model to go with is a major decision. While open-sourced models may seem cheaper initially, a new study warns that those savings can evaporate fast, due to the extra computing power they require. In fact, open-source AI models burn through significantly more computing resources than their closed-source rivals when performing the same tasks, according to a study published Thursday by Nous Research. The researchers tested dozens of AI models, including

ChatGPT’s mobile app is raking in the revenue. Since launching in May 2023, ChatGPT’s app for iOS and Android devices has reached $2 billion in global consumer spending, according to a new analysis by app intelligence provider Appfigures.

Is a refurbished MacBook viable in 2025? I did the math, and here's my expert advice

zdnet.com Kyle Kucharski 2025-11-20 08:39:00

Kyle Kucharski/ZDNET I remember when people used to scoff at refurbished tech. Buying a used phone or computer was like rolling the dice: you never knew exactly what you were getting. Well, the times certainly have changed. And, in this economy, the prices on refurbished tech are looking more and more tempting. Consumers are challenging this idea that we're all supposed to buy brand new phones and laptops every few years, and in the process, the market for refurbished tech has blown up. Also:

Pokemon Legends: Z-A Hands-On: Trying Out Real-Time and Mega-Evolution Fights

For Legends: Z-A’s battle system, I rewired the Pokémon part of my brain

theverge.com Kallie Plagge 2025-11-20 08:00:00

Even if you’ve never played a Pokémon game before, you can probably figure out how the type chart works. Fire types are weak to water types, water is weak to grass, and grass is weak to fire. Type matchups are foundational to Pokémon battles, far before you get into the weeds of stats and strats. I’ve had the Pokémon type chart memorized for around 25 years. That still didn’t stop me from making a rookie error in Pokémon Legends: Z-A. I panicked and sent out my Weedle against an NPC’s Pidgeotto

I love my grill, but standing over blazing flames in 90-degree weather isn't my idea of summer fun.

These compact powerhouses cook quickly while using far less energy than a traditional oven, making them a perfect heat wave solution.

‘Witchboard’ Summons a Fun but Uneven Remake of a Cult Classic

gizmodo.com Cheryl Eddy 2025-11-22 12:00:48

Released in 1986, the original Witchboard‘s cultural impact lingers mostly because it stars Tawny Kitaen—known more for being a music-video vixen than an actor. But the stunt casting works: her character’s Ouija board curiosity turns tragic when an evil spirit takes a shine to her, possibly lured in by her perfectly teased hair. The movie delivers more cheese than frights, but you can easily see why it became a cult classic. Less clear is why Witchboard needed a remake, especially one that only

Why You Can’t Trust a Chatbot to Talk About Itself

When something goes wrong with an AI assistant, our instinct is to ask it directly: “What happened?” or “Why did you do that?” It's a natural impulse—after all, if a human makes a mistake, we ask them to explain. But with AI models, this approach rarely works, and the urge to ask reveals a fundamental misunderstanding of what these systems are and how they operate.
