💥 Read this must-read post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: Easily extensible autograd implemented python with pytorch API. Uses numpy to do the heavy-lifting. Implementation is very similar to pytorch (graph-based reverse-mode autodiff). It wouldn't be too tough to extend the autograd, implement torch.nn, and possibly run on GPU (presumably with CuPy or Numba). It would be an interesting (but useless) endeavor to rewrite mytorch in a low level language using BLAS library calls instead on numpy, just like pytorch. mytorch supports the computation of arbitrarily high derivatives for both scalars and non-scalars. Both torch.autograd.backward…

🚀 Check out this awesome post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: Preface: the following post was written in the context of the events that happened in September. Some time has passed, and I held off on publishing in the hopes we could reach a happy ending with System76. As time has passed, that hope has faded. Attempts to reach out to System76 have not been productive, and I feel we’ve let the impression they’ve given the wider tech community about GNOME sit for far too long. Some things have changed since I originally wrote the…

It eliminates many stubborn instances of undefined behaviour, like use-after-frees, double frees, null pointer dereferences and the use of uninitialised memory. Xr0 uses C-like annotations to verify code: void * alloc() ~ [ return malloc(1); ] /* caller must free */ ⚡ More about the annotations They’re attached to every function that is potentially unsafe and express what its callers need to know to use it safely: void * alloc_if(int x) ~ [ if (x) return malloc(1); ] /*…

A few months ago, I was at Xsight Labs in California and saw the company’s E1 DPU PCIe card. A few weeks after that, a 1U chassis arrived. We wanted to start our series with a quick look at the really neat DPU, as this is far different from the DPUs we covered a few years ago. If you have not heard of Xsight Labs, we first covered them in 2020, and their X2…
✨ Read this awesome post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: Crystal radios are famous for doing something almost magical: picking up broadcast signals with nothing more than a diode, an antenna, and a pair of headphones. They’re the simplest RF receivers you can build — and a brilliant way to learn how radio waves become electrical signals. In this post, I’m taking that idea into the modern world. Using just two components — a high-speed Schottky diode and an LED — you can build a tiny “crystal detector” that responds to 2.4 GHz Wi-Fi, Bluetooth,…

The people who moderated for free, who wrote detailed answers, who curated niche communities. What remained? A sea of low-effort screenshots, rage bait, and "AI told me this" posts. The API changes weren't about costs. They were about control. Reddit wanted to own the entire user experience, monetization be damned. Third-party apps made Reddit usable…
