ukd1··on ICE Is Buying a Tool to Track Phones, Without Warrants
"You" are, by not sharing your location with countless random startups. But, seemingly that's not working.
ukd1··on If you have a Claude account, they're going to train on your data moving forward
I think I'm fine with the whole getting better due to something helped it / co find with it. I'm not happy if it's directly 1:1 or attributed to me - chatham house rule for this would be great.
ukd1··on Cloudflare to introduce pay-per-crawl for AI bots
meh. ads for ai content is really the answer -

e.g "OpenAI ads" content creator puts a tag on their page / set their domain - when the crawler sees it, display an ad pass on $ as usual.

ukd1··on Ask HN: Who is hiring? (June 2025)
9 Mothers Defense | Embedded Robotics Eng. & Computer Vision / ML Data Scientist | Hybrid (Austin TX) | Full-time

Embedded Robotics: Python on Jetson, CAN (+ EtherCAN / EtherCAT) drive buses, high-speed cameras, real-time PID/servo control, ROS, TensorRT

Computer Vision / ML: detection + tracking, transformer-based visual models, TensorRT tuning on Jetson

US persons only (e.g. green-card, citizens). Shoot your résumé / GitHub and a quick note on why you're good fit to jobs@9mothers.com

ukd1··on I maintain a 17 year old ThinkPad
I have few old thinkpads X220, X230, etc - outside of raw power, the two things that really suck are the speakers (they're truly trash), and the standard screen's performance with anything but trivial light around it.

Still, it's fast enough to use with linux, and the keyboard is a joy to use. Swappable batteries are fun, and useful.

However, I can't really use one outside of just nostalgia, or for tuning cars.

ukd1··on EA Open Sources Command and Conquer: Red Alert, along with other games
Could be, though also maybe optimization?
ukd1··on AI killed the tech interview. Now what?
Pairing on something close to whatever real work they'd be doing, but familiar to the applicant is my favorite way to evaluate someone (e.g. choose a side project, pre agree adding a feature).

I don't care if someone uses modern tools (like AI assists), google, etc - e.g. "open book" - as that's the how they want to work. Evaluating their style of thinking / solving problems, comms, and output is the win.

ukd1··on Fair Pricing
Ditto - I've been a paying user since June 22. I've basically used Google a handful of times since, and been disappointed each time. Well worth it.
ukd1··on Show HN: Design/build of some parametric speaker cabinets with OpenSCAD
Showing OpenSCAD without showing any code, or even really talking about the code is a real shame - there are some cool ideas in here, but none are shown (e.g. "I even made an algorithm to calculate the screw positions evenly").
ukd1··on Dusa Programming Language (Finite-Choice Logic Programming)
Yay RC. I was in a remote batch. Was great.

Zig was also apparently partly developed whilst Andrew Kelley was there. Fun place.

ukd1··on AI Brad Pitt dupes French woman out of €830k
This isn't the timeline. She decided to get divorced midway through this scam, and used the proceeds to help Brad.

lol, everything starts somewhere - use some imagination.
ukd1··on Steam games will need to disclose kernel-level anti-cheat on store pages
Yes; but more like the apple App Store - they take a cut, and (to some/varying extent) try to ensure some level of legitimacy / quality.
ukd1··on Steam games will need to disclose kernel-level anti-cheat on store pages
Oh it's a solution, it's just worse than kernel-level - as it's much easier to bypass.
ukd1··on Bop Spotter
100% - after I left my last startup I was in that frame; I did recurse.com and it really helped rekindle that spirit.
ukd1··on Raft: Understandable Distributed Consensus (2014)
Having implemented it twice (for fun/learning, though) I think you're right - yet it's also the easiest, imho. The paper, and resources around implementing it (posts, other implementations) are great. Also, the authors still reply on github when issues are opened, which is great.
ukd1··on Ask HN: Where to find domain experts for 1:1 tutoring?
I've had luck on Reddit; usually programming related job boards or "who's hiring threads" - asking for hourly tutoring / pairing for specific things (e.g. rust).
ukd1··on Launch HN: Moonglow (YC S24) – Serverless Jupyter Notebooks
GPU time
ukd1··on Show HN: PgQueuer – Transform PostgreSQL into a Job Queue
A common schema is one nice thing, but imho the win of these db backed queues is being able to do things, including enqueue background jobs in a single transaction. e.g. create user, enqueue welcome email - both get done, or not - with redid-based, this is ... not usually a thing; if you fail to do one, it's left half done, leading to more code etc

p.s. I maintain a ruby equivalent called QueueClassic

ukd1··on How Uber tests payments in production
My last company, Rainforest QA, developed issuing virtual credit-card numbers for just this purpose - kinda like the ones used for privacy.com. Customers use them for testing in prod. Simple, effective - and testing the exact same flow as customers.

Before this, we found a lot of teams using either their own corp cards, or pre-paid visa type things. All, a pain to manage balance wise.

Seemingly, the biggest problem left with doing this is production metrics; these transactions in prod tend to affect the main metrics - either your own, or payment related things.

I can't find anything current, but - https://www.businesswire.com/news/home/20180417005414/en/Rai... covers it.

ukd1··on Surprise, your data warehouse can RAG
For me it's nice to see the re-use of existing infra - big query. Personally, I was rooting for Postgres, but your logic of why not makes sense! Great post.
ukd1··on Show HN: A modern Jupyter client for macOS
ah, I def need remote for my current use case - the web interface just isn't that nice to use!
ukd1··on Surprise, your data warehouse can RAG
Is $0.01 per retrieval a lot, or not?
ukd1··on Psion 5mx Emulator
Thanks - good point - though I've not had time to look yet!
ukd1··on Psion 5mx Emulator
I had one in highschool, and a 3a before that in high school - at the time no one else (at least in my school) used a laptop/equiv; I managed to be allowed as a dispensation due to dyslexia and illegible handwriting. The keyboard on the 5 was a vast improvement over the 3a, as well as the OS. I did quite a lot of programming directly on it - I remember OPL being one (only?) of the languages built in - https://en.wikipedia.org/wiki/Open_Programming_Language

My mother came to visit me recently, bringing my 5 back - unfortunately it looks like I left the batteries in all those years back and they leaked, so it's likely dead.

ukd1··on Photography Laws in Germany
Interesting; is that the same for banks / building security? That sounds like it disallows dash cams too?

edit: did some digging on dash-cams, seems like they're legal if they're recording on a loop, and save permanently with some user-interaction.

Security cameras must have signs, and not cover outside your property. Storage is (suggested? allowed?) for 24-48 hours. You can request footage of yourself from anyone (even private?), but they have 1 month to reply to a request - so seems practically pointless given the recording storage length.

ukd1··on Photography Laws in Germany
How does this affect the police in Germany and their ability to record / photograph? What about security cameras, or doorbell cameras - are they illegal, or is consent applied by someone approaching them?
ukd1··on Australian man says border force made him hand over phone passcode
At least they didn't try enforce real (jail time) penalties for not disclosing; Australia, the UK and others have key-disclosure laws - https://en.wikipedia.org/wiki/Key_disclosure_law#Legislation...
