(Elon Musk then immigrated to the USA on a student visa but never enrolled at the university that accepted him, which means he was an illegal immigrant and worked illegally; this is the same guy who says his cars won't be able to leave the country in case of a military draft because of "civic duty". You cannot make that up.)

🐙🥊 are famous for being loners, but new footage shows they actually lead "hunting parties" made of several different species.

When the fish partners don't pull their weight or try to steal a meal, the octopus uses its arms to physically punch them.

🚨 Fast jeden Tag ein Angriff – Rechte Gewalt hat in Brandenburg auch 2025 weiter zugenommen!
Wir haben heute unsere Jahresstatistik veröffentlicht. Mit 290 Angriffen mussten wir erneut einen Höchstwert verzeichnen.
Rassismus war wieder das Hauptmotiv der Täter*innen. Besonders in den Fokus gerieten zudem Wohnprojekte, Jugendclubs und soziokulturelle Zentren.

Unsere ausführliche Analyse: opferperspektive.de/aktuelles/

Pixelfed does too many things.

I now realize that. We need to focus on improving core features and make them stable and rock solid across web and mobile.

Collections, Portfolios and Stories are really cool features.

But more importantly we need to improve format support, allow mixed albums (video + images), preserve ICC profiles and allow you to tag any location, not just the few known ones, just to name a few.

We have a lot of work to do, but I’m confident that I can make this happen. 🚀

Google sets new 24-hour process to sideload unverified developers Android apps. That is right. Now you can't load apps without google's permission and flow control. Who knows after sometime they might think 72 hours delay is needed and so on. More info android-developers.googleblog.

Google says this is to stop malware from stealing passwords, OTPs, and bank/card info. Do you think these steps will actually stop scammers who call and pressure people into installing malicious apps?

Title: Advanced flow for power users to sideload apps from unverified developers It shows a 4 step security process: 1) confirming no one is coaching you 2) restarting the phone to cut off remote access 3) a 24-hour security delay to install the sideload app using unverified developers 4) final confirmation and enabling of settings

🆕 blog! “I'm OK being left behind, thanks!”

Many years ago, someone tried to get me into cryptocurrencies. "They're the future of money!" they said. I replied saying that I'd rather wait until they were more useful, less volatile, easier to use, and utterly reliable.

"You don't want to get left behind, do you?" They countered.

Many years ago, someone tried to get me into cryptocurrencies. "They're the future of money!" they said. I replied saying that I'd rather wait until they were more useful, less volatile, easier to use, and utterly reliable.

"You don't want to get left behind, do you?" They countered.

That struck me as a bizarre sentiment. What is there to be left behind from? If BitCoin (or whatever) is going to liberate us all from economic drudgery, what's the point of "getting in early"? It'll still be there tomorrow and I can join the journey whenever it is sensible for me.

Part of the crypto grift was telling people to "Have Fun Staying Poor". That weaponisation of FOMO was an insidious way to get people to drop their scepticism.

I feel the same way about the current crop of AI tools. I've tried a bunch of them. Some are good. Most are a bit shit. Few are useful to me as they are now. I'm utterly content to wait until their hype has been realised. Why should I invest in learning the equivalent of WordStar for DOS when Google Docs is coming any-day-now?

If this tech is as amazing as you say it is, I'll be able to pick it up and become productive on a timescale of my choosing not yours.

I didn't use Git when it first came out. Once it was stable and jobs began demanding it, I picked it up. Might I be 7% more effective if I'd suffered through the early years? Maybe. But so what? I could just as easily have wasted my time learning something which never took off.

I wrote my MSc on The Metaverse. Learning to built VR stuff was fun, but a complete waste of time. There was precisely zero utility in having gotten in early.

Perhaps there are some things for which it is sensible to be on the cutting edge. I took part in a vaccine trial because I thought it might personally benefit me and, hopefully, humanity.

But I'm struggling to think of anyone who has earned anything more than bragging rights by being first. Some early investors made money - but an equal and opposite number lost money. For every HTML 2.0 you might have tried, you were just as likely to have got stuck in the dead-end of Flash.

There are a 16,000 new lives being born every hour. They're all starting with a fairly blank slate. Are you genuinely saying that they'll all be left behind because they didn't learn your technology in utero?

No. That's obviously nonsense.

It is 100% OK to wait and see if something is actually useful.

Dear followers and "fellow kids,"

In hopes of landing an interesting and fulfilling gig next, I just wanted to let you know that I'm ready for new assignments. Preferably helping companies with digital transformations that keep people at the centre. My 25 years of experience in the IT industry have taught me one essential thing: efficiency and quality are achieved only when happy people work closely together, within and across teams in the whole enterprise.

More on LI: linkedin.com/posts/trondhjort_

How do you do, fellow kids? (old man with a skateboard, 30 Rock)

国会前とかの反戦デモはすごく大事だと思うんだけど、「家賃下げろデモ」も同じくらい大事だと思うんだよね。私は数年前にやってた「最賃上げろデモ」には何回か参加したんだけど、そんなに人数が増えなくて。日本の左派は経済イシューにちょっと冷たい印象があるんだよね。だからインボイス反対運動も右翼に軒を取られてしまった感じだし。

Flash-KMeans: Fast and Memory-Efficient Exact K-Means

Link: arxiv.org/abs/2603.09229
Discussion: news.ycombinator.com/item?id=4

Flash-KMeans: Fast and Memory-Efficient Exact K-Means

$k$-means has historically been positioned primarily as an offline processing primitive, typically used for dataset organization or embedding preprocessing rather than as a first-class component in online systems. In this work, we revisit this classical algorithm under the lens of modern AI system design and enable $k$-means as an online primitive. We point out that existing GPU implementations of $k$-means remain fundamentally bottlenecked by low-level system constraints rather than theoretical algorithmic complexity. Specifically, the assignment stage suffers from a severe IO bottleneck due to the massive explicit materialization of the $N \times K$ distance matrix in High Bandwidth Memory (HBM). Simultaneously, the centroid update stage is heavily penalized by hardware-level atomic write contention caused by irregular, scatter-style token aggregations. To bridge this performance gap, we propose flash-kmeans, an IO-aware and contention-free $k$-means implementation for modern GPU workloads. Flash-kmeans introduces two core kernel-level innovations: (1) FlashAssign, which fuses distance computation with an online argmin to completely bypass intermediate memory materialization; (2) sort-inverse update, which explicitly constructs an inverse mapping to transform high-contention atomic scatters into high-bandwidth, segment-level localized reductions. Furthermore, we integrate algorithm-system co-designs, including chunked-stream overlap and cache-aware compile heuristics, to ensure practical deployability. Extensive evaluations on NVIDIA H200 GPUs demonstrate that flash-kmeans achieves up to 17.9$\times$ end-to-end speedup over best baselines, while outperforming industry-standard libraries like cuML and FAISS by 33$\times$ and over 200$\times$, respectively.

llms meta, guns

imperfect metaphor:
it's as though suddenly a large number of people i spend time around have recently decided to take up shooting guns as a hobby, and now everyone feels compelled to consider whether that's a hobby they should also adopt or else come up with a justification (ethical or otherwise) for why they're not going to, and it takes over every conversation. the kind of talking past each other around ethics, power, being "pro" or "anti", etc also feels similar

오늘은 깊게 쌓인 스트레스가 묵직한 압력을 만들어서 폭발할지도 모르는 상태였다. 다행히 사고 안치고 하루를 마감하게 된 것에 감사하다. 나의 지랄맞은 성격을 잘 보여준 팀원들에게도 정말 고맙게 생각한다.

사무실에서 나서기 전만 해도 심각한 상태였는데 불과 두어시간만에 돌아보니 그 때 컨디션 조절을 완전히 실패하고 있었구나 싶다.
