Helium wird nicht "produziert" (dafür bräuchte man einen Stern) sondern durch verschiedene Prozesse extrahiert. Entweder aus der Atmosphäre oder aus Einlagerungen in Öl- und Gasvorkommen.

Das Emirat Qatar beliefert etwa 30% des Weltmarktes. Das Edelgas ist in der Halbleiterbranche unersetzlich.

Qatars größte Extraktionsanlage wurde gerade zerbombt und ist wahrscheinlich für ca. 5 Jahre nicht mehr lieferfähig.

Computerchips werden noch viel teurer werden.

維修

這不是新聞 @index@thisisnot.news

家人又不滿意新家中的天花了。因為看著似乎有水氣,於是要求維修部整個天花板的油漆全部都鏟去,重新再上油漆。這使得所有客廳的東西要搬入房中。

父親不知為何,這段時間變得很怕髒,於是家中許多東西都被封鎖起來,包括光纖路由器也拆下,以至於家中無無線與有線網路;甚至正門都被封死,必須從工人電梯出入。

這篇文章也是通過手機共享網路至 iPad 所寫的。本身也有想希望在公司寫文,但這段時間事情又特別多;剛解決完某保險公司的產品安全問題,某個來自新加坡銀行又提離譜之安全需求,甚至驚動公司的 CEO 下來親自和客戶談判。也正因此,最近我幾乎都是在開會中度過的,每天都有3到5個會議,不知道的以為我升上管理層了;再加上要開發新產品,基本上這幾日在公司抽不出時間去思考寫文。最多也只能在編譯之時順便寫一些自己的東西,比如最近自己突發奇想開始做的 laapsaap.io (垃圾軟體庫),不過也只有做一個打底。

在家中因為 PC 沒有網路,這幾日泡在 Steam Deck 之中。之前有玩 「The Case of the Golden Idol」 這一款偵探解謎遊戲,個人十分喜歡,於是最近購買了 「The Rise of the Golden Idol 」,正好趁著這時候稍微玩了些許。正值春季促銷,目前也在打折,如果喜歡文字偵探類解謎遊戲的人不妨可以一試。

但是寫文與伺服器維護,我還是選擇不打開 Linux PC,而是直接在 iPad 上使用;這些簡單的任務就不必我的 5080 去工作了。寫文我還是會使用之前我在使用的 iA Writer,而對於伺服器維護,在 iOS 上我長期使用 a-Shell 這一款終端。這款終端程式可以原生使用 sshvim 等程式指令,也可原生使用其做 Lua、Python、JavaScript、C 與 C++ 的編程,同時也集成 Shortcuts 支援,可以說是 iOS 上的終極神器,在沒有 Linux 時候的 Linux 替代品(不是)。

不過說到 Linux,最近 Kagi 的 Orion 瀏覽器發佈了 Linux Beta 版本,Opera GX 也正式發佈了 Linux 版本,GNOME 50 正式發佈正式移除 X11 支援,而 Mac 用家也可以享受 Fedora Asahi Remix 43。不過我最期待的是支援 Nvidia 595 版本驅動程式的 Proton;在前幾日,Nvidia 發佈了 595 預覽版本驅動程式,這個版本最大的重點便為 DirectX 12 遊戲效能修復,但需要對應的 Proton 支援。

雖然有這些很開心,但還是用不來 PC,還是要等到下週二工程結束才可使用。

啊好煩。

工作也好煩。

我什麼都做不到。

就聽一些奇怪的東西吧。

(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.)

🚨 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/

Umrisskarte von Brandenburg mit eingezeichneten Landkreisen und der jeweiligen Zahl rechter Angriffe pro Landkreis. Die höchsten Werte haben die Landkreise Märkisch Oderland und die Stadt Cottbus.

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.

That struck me as a bizarre sentiment.…

I'm OK being left behind, thanks!

shkspr.mobi/blog/2026/03/im-ok

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

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
