Hello friends! I love to talk about AI, programming, gaming, and climbing. Here's a brief bio: - Programmed since I was 12. - Contributed to OSS since 2001. - PhD in Statistics. - Former AI Research Scientist. - Software Engineer. - Currently working with satellite data. Nice to meet you 🤗

I'm heading to Bologna on Wednesday for @rustlab.it. If you see me at the conference, please say hi. Maybe we can chat about Rust or whatever else during a coffee break 🙂🦀

This interview has almost 1 million views in four days and has generated a big new wave of interest in "The Nerd Reich." Here's how I explained tech fascism to DW News (German public media) on a windy beach near the Golden Gate Bridge. 🌉 www.youtube.com/watch?v=2176...

I certainly hope nobody makes the mistake of conducting business with this company in the future, or involving them in any processes.

Deno v2.9.8 is a security release addressing the eMudhra vulnerability by distrusting the compromised certificate authorities. Also includes 12 other security and bug fixes. Upgrade now: deno upgrade github.com/denoland/den...

Rustup 1.29.2 has been released. This is a small release which only updates the rustls-webpki and webpki-root-certs dependencies to remove the compromised eMudhra intermediate certificates. See the announcement for details: blog.rust-lang.org/2026/10/20/R...

The US knows Ukrainian air defense relies on US early detection of Russian launches. Without telling Ukraine, the Trump White House (and Elon Musk's SpaceX) withheld that info and hindered countermeasures. The US just facilitated a Russian attack on Ukraine, making it more effective and deadlier.

Russian strikes killed over 80 Ukrainian civilians in two days. Moreover, it has stepped up its hybrid attacks against Europe, both EU Member States and NATO Allies. Suspending sanctions on Russian diesel provides Moscow with more revenues to wage war.

Besides libraries, what are the best stores for ebooks that are DRM-free, or at least easily liberated? Looking to buy a bunch of ebooks to read on my Xteink X4 Pro.

Stop. Listening. To. Tech. Bros. They. Are. Not. Human. They. Are. Slop.

It's heart-warming to watch tech bros who deny the humanity of many groups of people based on different kinds of bigotry so intent on convincing us that their imaginary friend is human.

🚨 [Token][ization] Paper Alert 🚨 Tokenization is a wildly understudied area of language modeling despite it having effects across all of NLP. Over the past ~8 months, 32 (!) tokenizer researchers put together the most comprehensive survey of the field. Check it out!

Who wants to come to the Netherlands next month? Check out TechoramaNL! I'll be giving a full day software architecture workshop and presenting, along with a ton of amazing speakers!

Hypothetically, is anyone looking to hire someone with a strong background in software engineering, a PhD in AI/ML, multiple years of real-world Rust experience. Additionally, this hypothetical person has experience with CUDA, autonomous drones, and satellite imagery.

Denmark is trolling Trump.

My copy of The Nerd Reich by @gilduran.com should be arriving in a couple of days. I can't wait to read it, even though I'm scared my outlook on the future will be even more grim.

Is it worth getting one of the new base Mac Mini (M6, 16 GiB RAM, 256 GiB SSD) units, or should I bump some specs? I'll mainly be using it for Rust and embedded development. I don't really care about local LLM/agentic coding.

I really wish I didn't have to wait 4-6 months for my Microduck to ship, but it's really awesome so many people have ordered one. I'm expecting there to be a pretty big and vibrant community. Stoked to share my journey! 🦆

Tonight's view from my balcony. I'm never gonna get tired of this place.

The Internet was nice while it lasted.

⚠️ We believe that there is an ongoing campaign targeting owners of popular crates and rust-lang team members that is attempting to compromise devices and accounts in order to use them to publish malware. See our blog post for details: blog.rust-lang.org/2026/09/17/t...

The only problem with the Microduck from Pollen Robotics (aka. @hf.co) is the extremely long shipping timeframe. I'm not getting mine until sometime next year 😢

I'm going to @rustlab.it again this year! This will be my third year in a row attending my favorite conference ever. I've been lucky enough to attend a lot of dev conferences all over the world, including the very first NDC, but RustLab is my favorite. If you see me there, say hello! 🙂

Does anyone on here have any experiences to share about the Fairphone, specifically the 6 or 6 plus? I'm growing increasingly eager to disconnect myself from Big Tech, and looking for a phone that I can repair myself. Share both good and bad. Feel free to share other phone recommendations as well.

I'm looking for a really tiny USB-C drive with at least 8 GiB of storage, or at least enough for a functional Tails setup. Does anyone have any recommendations? I've found plenty of USB-A drives, including those pretty cool bracelets. However, I really want USB-C.

Any decent SDRs that are capable of receiving and transmitting over UHF, VHF and HF? Ideally I want something portable or at least semi-portable. Full kit is a bonus, but not required; I can provide my own antennas.

I wanna do one last startup before I get too old. I've got tons of ideas, but none feel viable long term. I don't want to just start something and then sell out. I wanna nurture something and make it live on long after I retire (30 years from now). Maybe I'll just get go into woodworking instead 🙂

#jj-vcs interoperability with Git continues to be key. The fact that ERSC can swap out the repo storage to not use Git, *and* can have a migration path to a future, better wire protocol than Git's, while preserving compatibility along the way, is amazing!

Anyone know approximately when the RustConf recordings will be posted online? I missed all of this year due to other commitments.

I missed the RustConf sessions yesterday. What were the most enjoyable or inspiring ones you watched?

I'm feeling burned out and disillusioned. I've got so many ideas I want to put out into the world, but I never manage to find the energy to do it. Something needs to change. Ideas are worthless, execution is everything.

I'm glad to see Rust become a "tier 1" language at Microsoft. Personally, I hope this means more folks actively working on the Azure SDK crates. Those crates have come a long way in the past year, which is great, but we're still missing important support like Azure Service Bus.

Nice! I've used PB on Chrome for many years. Glad to see it finally make its way to Safari 🥳

I keep offending some folks from the US with my "crazy socialism" and militant opposition to profit maximization. When your whole worldview is built on lies the most natural response is denial and other defensive behaviors. I'm not here to offend people though, so I'll revert to Rust and AI/ML 🙂

We've been cooking at @ersc.io "What comes after git" ersc.io/blog/what-co...

I've been "slightly" too ambitious on a passion project involving Rust and ESP32-C3 SoCs. I started to develop my own barebones OS, but I've realized I need to pivot to Embassy. My OS kinda works, but I don't really need an OS. Also, I'm brand new to RISC-V, so everything is 10x harder.

exclusive: hands-on with the Duo

Steve Jobs never would have signed off on this nonsense. I was hoping so long that the iPhone Duo rumors were false. Nah, this is not the Apple I used to respect and admire. It makes me sad.

The single biggest issue with the iPhone Duo, besides possible hinge issues, is that the folding screen needs to be plastic in order to bend. Plastic screens are terrible when compared to the glass screens we've grown accustomed to.

Here we go; the iPhone Duo coming up. I'm skeptical.

putting mathematicians out of a job with AI is a rookie game introducing CEOBench,

Basically none of the best new iPhone and iOS features will be available in the EU/EEC and China. I guess this will be the first year in over a decade I will not be upgrading to the latest iPhone.
