The plot doesn't appear to be in Amdahl territory yet. The single-threaded time in the plot looks to be around 39 seconds. A perfect division into 32 workers without overhead would…

This is well-written. I could follow along quite nicely, from the setup through the bottlenecks and onto the resolution of the performance bug. Even the PRs are very pleasant to re…

What exactly do subagents do that I can't replicate with a simple skill that tells an orchestrator to create subshells for tasks, each running `codex exec`? I've been doing this wi…

...aaaand we're down to 112997 now.

Querying the API, there seem to be 112998 artworks with this label as of this moment. (I'm deliberately not posting the direct API call in case it's expensive for them to run. Docu…

Ok, fair points, including the sister comment, it's likely not a drop in O2 levels. But then why can we see problems with concentration in studies of people in poorly ventilated ro…

I don't think you can cleanly compare this: In the study, they added CO2 to the room, while keeping O2 at normoxic levels throughout the experiment. In your meeting room, O2 levels…

John Oliver had a segment on prediction markets this week. It covers insider training and opportunities for blatant manipulation like this, well worth checking out. The example in …

While the trash can generation was somewhat present and around, I don't think I ever saw a cheese grater in the flesh. Did it have any users? Were there any actual useful expansion…

The original title of the document is “The future of software engineering”, which is so generic that I chose to ignore the HN rule to not editorialise, in this case, and picked one…

I don’t think learning and understanding is hard-coupled to performing all low level steps yourself. The LLM can be a developer, sure. But it can also take on the role of rubber du…

An iterative prompt with GPT-5.2 on Copilot CLI spits out a dense two-page proof for problem 10 after less than 60 minutes of working. A review of the generated proof with Claude 4…

A clearly defined/testable long-horizon task: demonstrating the capability of planning and executing projects that overrun current llm's context windows by several orders of magnit…

At the current rate of progress I'm wondering how long it will take for llm agents to be able to rewrite/translate complete projects into another language. SQLite may not be the be…

That is factually incorrect. The primary source is wind at 132 TWh in 2025, followed by solar with 70 TWh. Lignite was third with 67 TWh and hard coal sits at 27 TWh. https://www.e…

Great technical demo, but the usability feels unpolished. So here's a little bit of feedback of trying this out on a piano: Just because my piano has 88 keys doesn't mean they are …

The password and pwbuf arrays are declared one right after the other. Will they appear consecutive in memory, i.e. will you overwrite pwbuf when writing past password? If so, could…

“With Series 3, we are laser focused on improving power efficiency, adding more CPU performance, a bigger GPU in a class of its own, more AI compute and app compatibility you can c…

Wouldn’t a multiple of the resonance frequency also be problematic then? Why doesn’t the axle disintegrate at 4800 rpm?

Just use the non-codex models for investigation and planning, they listen to "do not edit any files yet, just reply here in chat". And they're better at getting the bigger picture.…

Apple acquires OpenAI, Sam becomes CEO of combined company; iPhone revenue used to build out data centers; Jony rehired as design chief for AI device.

This is a good resource. But for the computer vision and machine learning practitioner most of the fun can start where this article ends. nvcc from the CUDA toolkit has a compatibi…
