It says 8 Arm Neoverse N2 cores in the blog post. So not directly ARM Cortex, derived from ARM Cortex-X3 but same family as NVIDIA Grace, Google Axion and AWS Graviton4.

Show HN: Stillwind – High Resolution Electronic Component Search

hannesfur — Thu, 11 Jun 2026 18:12:46 +0000

We’ve spent the last couple of months building Stillwind Search, a search engine for electronic components that helps users find parts that fit even the most complex set of specifications.

After talking to the people that actually build PCBs we found out that finding the exact part you are looking for, is consuming enormous amounts of times, is very tedious and then often doesn’t yield the best results. So we tried to cut down this search time by just requiring a (broad) description of the specifications and we find the correct part in minutes, not hours.

This is possible through our own database of parts and their properties. We used LLMs to extract every parameter about a part into >1k schemas, collectively covering more than 130k properties. This depth of properties could no longer be visualized, so the database is queried interactively by an AI agent (Sonnet 4.6) to find the needle in the haystack of parts. Before results are shown, we use another model to verify the data (that’s why it might take a moment before the first results appear).

We currently have almost all microcontrollers, sensors, and other advanced ICs on the market, as well as a wide selection of passives and generic parts. We are working on adding more parts and are more than happy to take suggestions.

I know that folks on HN like technical details on how this works, so let me give a short overview: Frontend: SvelteKit + Cloudflare Workers + Hyperdrive Backend: PostgreSQL 18 (with io_uring) database, with extensions on NVMe drives hosted on a beefy server.

We appreciate all feedback and are happy to answer any questions :)

Btw: We are already working on a way that you can search combinations of parts, finding the optimal combination of parts.

Not across all features, but certainly in specific ones. There are more advanced WiFi 6 chips, more advanced Bluetooth chips and faster MCUs. But they are all separate chips or companion ICs.

It has become limited. Some have WiFi, some have Bluetooth but rarely both. There is the SiWx917M (https://www.silabs.com/wireless/wi-fi/siwx917-wireless-socs) by SiliconLabs though.

If we include western companies you get the NXP RW612 (https://www.nxp.com/products/wireless-connectivity/wi-fi-plu...) which is dutch.

There is an ESP-C5 (https://www.espressif.com/en/products/socs/esp32-c5) that supports 2.4 and 5 GHz dual-band WiFi. And unlike the ESP32-S31 you can buy it today.

From the EXIF we can infer that every setting was left at the default. No exposure comp, no contrast, no HSL, no lens correction and a linear tone curve. Just the default Adobe Color profile at 5400K.

Looking at the EXIF (with exiftool) for the image uploaded by NASA (https://www.nasa.gov/wp-content/uploads/2026/04/art002e00019...), apparently this was taken by a Nikon D5 with an AF-S Zoom-Nikkor 14-24mm f/2.8G ED and developed with Lightroom. It also seems like very little was done in Lightroom. Amazing... I dumped the whole EXIF here: https://gist.github.com/umgefahren/a6f555e6588a98adb74eed79d...

That’s fair but when there is an async version of the driver or Hal available it should be pretty straightforward to port it to synchronous, right? Maybe Claude code can even do it with minimal supervision…

Edit: Replace blocking with synchronous

I am a big fan of the embassy project and it’s a great example of why async Rust is so great: Because this is possible. It works without a heap, is a really low cost abstraction and you can do stuff concurrently on a single core chip (where you can’t just spawn a new “thread”) and you don’t have the complexity of an RTOS. I believe there is a great future for embassy ahead and it’s so great how far the team has come.

I also want to give a shoutout to reqwless (https://github.com/drogue-iot/reqwless) which is a HTTP client for embassy-net that even supports HTTPS!

Rust embedded was really never actually better then C or C++ but embassy for me is a big reason why I now make my buying decision based on how well I can use Rust on the MCU.

Maybe stuff has changed a lot in the last year but I didn’t experience that problem so far. For me it was the other way around mostly. Where did you encounter that?

New comment by hannesfur in "Efficient method to capture carbon dioxide from the atmosphere"

hannesfur — Wed, 31 Dec 2025 16:00:20 +0000

Interesting thought but you would need a lot of these gasses on the one hand and on the other hand it doesn’t help in working against the greenhouse effect. The greenhouse effect depends on the absolute amount of CO2 in the atmosphere, not the percentage. How much infrared light is absorbed by CO2 primarily depends on the amount of CO2 in the atmosphere.

Maybe they felt the increase in capability is not worth of a bigger version bump. Additionally pre-training isn't as important as it used to be. Most of the advances we see now probably come from the RL stage.

This course is actually mandatory in the first year of the CS undergraduate program here at ETH. I remember it very fondly for its great (and passionate) lecture and the hands on experience building a MIPS cpu in the exercise sessions. Probably the best lecture in my undergraduate.

hannesfur — Thu, 16 Oct 2025 08:21:45 +0000

These seem like the first features that Rust in Linux bring to the Rust language that are not almost exclusively useful to the kernel. In my perception the focus on bringing features for the kernel has held up development in other parts of the language and the standard library.

hannesfur — Thu, 16 Oct 2025 08:15:47 +0000

It's great that they finally target all three mayor platforms! Let's see how developers using Windows treat them. I used to be a Neovim purist, spending days on my config and I have barely touched it since I moved to Zed. It's so much nicer to use then VScode (and it's forks) because it's so snappy. I hope they ship leap.nvim (https://github.com/ggandor/leap.nvim) support soon, then I am completely happy!

That's sadly true, over in x86 land things don't look much better in my opinion. The corresponding accelerators on modern Intel and AMD CPUs (the "Copilot PCs") are very difficult to program as well. I would love to read a blog post on someone trying though!

Edit: Foundation Models use the Neural Engine. They are referring to a Neural Engine compatible K/V cache in this announcement: https://machinelearning.apple.com/research/introducing-apple...

You probably wouldn’t with a Pro but you might between an iPad Pro and an MacBook Air. With the foundation models API they basically said that there will be one size of model for the entire platform, making smarter models on a MacBook Pro unrealistic and only faster ones possible.

Very cool! Since it’s possible to train foundation model adapters, is a library for user fine tunes possible?
