We can do better than line-buffered output
Buffered output typically comes in two flavors: fully buffered and line buffered. If output goes to a terminal then the implementation automatically selects line buffering, flushing its buffer when a line is completed so that it reaches the user immediately. Otherwise it fully buffers, holding output until the buffer…

Ripple-65B Preview: U.S. Open-Weight SOTA on Agentic Coding
We develop frontier AI methods to reinvent chip development, collapsing traditional design timelines, closing the loop between AI and the hardware that fuels it, and enabling a Cambrian explosion of custom silicon.

The lost malloc()
Prompted by another project idea that popped into my mind, I did some Unix archaeology and looked at the original sources . This is the most fun I've ever had reading someone else's code - probably due to the historical significance. But also because of how delightfully approachable it was, compared to modern…

LLMs are not superhuman at reading and writing neural network weights
A recent paper argues that frontier LLMs can work with neural network weights directly. This seems superhuman, but it isn’t. The paper shows that GPT-6 Astra…

Astra can read and write weights to improve Qwen
We find that frontier LLMs are surprisingly good at natively reading and writing neural network weights, using a variety of recent tools and algorithms or even via direct weight editing.

That morning I woke up at 6:58, two minutes before the alarm. I lay there and waited for it to ring. And it rang. We both did our jobs. I still don’t know why I remember it in such detail. I used to forget what I’d had for dinner the night before. And now I remember the whole morning minute by minute, as if someone…

Prospero: A new coding harness for a more civilized age
I’ve been fascinated with local LLMs for a couple of years now. The better open weight models, including some that inference on regular, higher-end consumer hardware at tolerable speeds, are now reliable enough to handle simpler programming tasks. This requires a coding harness, but so far this year I’ve been…

Switch Lowering in GCC
We have seen in a previous post that switch statements are more complex than they seem. The compiler is able to implement them as a decision tree (even though maybe it shouldn't). Is that everything it can do?

Why are good developers so wary of agentic development?
Good developers’ caution about agentic development comes from knowing that built isn’t the same as working in production.
