anonu··on France's aircraft carrier located in real time by Le Monde through fitness app
He's running laps while the ship is moving. The little circles is him backtracking against the direction of the ship. It seems to me the ship is just going in a straight line.
anonu··on A Japanese glossary of chopsticks faux pas (2022)
This would make a great poster to give to our local sushi bar chef/friend.

anonu··on Show HN: Will my flight have Starlink?
Weird take. The vast majority of US electricity infrastructure is privately owned and financed.
anonu··on US SEC preparing to scrap quarterly reporting requirement
> being listed on public exchanges is not a requirement

it used to be raise money. now that money is done privately. the result exacerbates the gap between private and public markets and ultimately between rich and poor. Private market participation is usually for accredited investors where you need $1m net worth.

Public markets are one of the best ways to create wealth in the US, if the historical record is any hint about the future. Fewer public companies gives regular investors less choice. So if you're a private company and you have 1/2 as many reports to file each year, well now you have a slightly less onerous reporting regime and slightly tilts in favor of going public.

anonu··on TUI Studio – visual terminal UI design tool
Claude Code built a TUI for me last night, in this case to step through nanosecond timestamped ITCH market data messages and rebuild an order book visual in the terminal. This type of stuff would have taken a day - but done in 5 minutes now.
anonu··on Ask HN: How to be alone?
Maybe the answer is: don't be alone. We are social animals at the core.
anonu··on Operational issue – Multiple services (UAE)
We have business in UAE. For whatever reason I defaulted to us-west-2 since these particular applications are not latency sensitive.
anonu··on Claude Status – Elevated error rates across multiple models
We need some competition in this space.
anonu··on Attention Media ≠ Social Networks
My mental model for all of this is that my attention is valuable. I can choose where to spend my attention and it should cost something to these platforms and their advertisers to command that attention. Unfortunately, these platforms have figured how to lower their cost by triggering lizard brain reflexes. The best solution is to simply remove any pathways they have to command that attention: uninstall apps and turn off all notifications. My attention is more under my control in this way.
anonu··on The Problem with LLMs
I stopped reading after "problem with LLMs is plagiarism"...
anonu··on How I Became a Quant (2007) [pdf]
This sounds like you're on a Pentium 386
anonu··on High-speed train collision in Spain kills at least 39
I don't want to speculate on this crash but my mental model for these things is that there's always a handful of factors that all align and converge to create an accident. Some factors are deep-rooted - and point to decisions made years ago - sometimes related to company culture. Theres always an element of operator error: someone ignored something due to inattention or sleepiness.
anonu··on The guide to real-world EV battery health
> How long do electric car batteries last?

The article never answers the question. But if you assume 70% end-of-life threshold with 2.3% loss per year - then we're looking at 13 years.

anonu··on The Olivetti Company
My dad speaks fondly of his time at Olivetti. He was a UMich EE grad from Lebanon. Through some chance encounters he had met some Olivetti execs who sent him a TELEX to his home in Lebanon offering him a job in Ivrea, which he took given that it was on the eve of the Lebanese Civil War (~1975). The rest is history...
anonu··on The recurring dream of replacing developers
AI won't replace developers. It will replace the bootcamp devs of the last decade. The average expectation is now much higher. AI tools will only elevate the expectations of what a human dev is capable of and how fast it can get done.-
anonu··on Ideas are cheap, execution is cheaper
Thats just not true. $CRM is at worst flat looking back 1 year. $IGV, software ETF is the same. Definitely not down 50%.
anonu··on Ideas are cheap, execution is cheaper
> Historically, sales was hard because you had to design and refine a sales motion around a product

while your statement is true - this is actually a very minor reason why sales is hard.

anonu··on [dead]
I am not sure its "not allowed". The abstract is interesting and thought provoking.

I would love to read the book but I personally don't have time for it - so most likely would not pay for it.

There is a danger in thinking of our "meat machines" in purely mechanical terms - so my first interest is whether whatever model being proposed can actually be adhered to. Or maybe an "AI Copilot" can implement such a framework and assist us mere humans in attaining our goals.

anonu··on Ask HN: What did you find out or explore today?
look into vector databases. for most representations, a column is just another file on disk
anonu··on Scott Adams has died
One thing I appreciated from Scott was his "compounded skills" concept. He explained it: he wasn't a very good writer or illustrator. But he combined those skills with some humorous business insights to make Dilbert.

That concept of merging skills stuck with me.

anonu··on The U.S. Government Just Followed Through on Its Ban of DJI Drones
They're not that hard to make. USA will be fine. If some of the software and hardware manufacturing expertise can be built here thats great.
anonu··on Total monthly number of StackOverflow questions over time
So the question for me is how important was SO to training LLMs? Because now that the SO is basically no longer being updated, we've lost the new material to train on? Instead, we need to train on documentation and other LLM output. I'm no expert on this subject but it seems like the quality of LLMs will degrade over time.
anonu··on Show HN: Website that plays the lottery every second
EV is always negative.
anonu··on Reminiscences of a Stock Operator (1923)
required reading when youre a young buck starting out on a trading desk. its a short, quick read. there's 2 key takeaways for me when comparing today's markets and those of 100+ years ago: market dynamics are essentially unchanged & human emotions - fear and greed - drive those market dynamics in the same way.
anonu··on Warren Buffett steps down as Berkshire Hathaway CEO after six decades
I think they are being hyperbolic.
anonu··on Warren Buffett steps down as Berkshire Hathaway CEO after six decades
He said he would keep writing at least once a year.
anonu··on Tell HN: Merry Christmas
you never really die on the internet.
anonu··on Autoland saves King Air, everyone reported safe
Claude "fly this plane"
anonu··on Go ahead, self-host Postgres
does self-hosting on EC2 instance count?
anonu··on MIT Missing Semester 2026
I always thought this practical side of development was missing in a CS or engineering curriculum. This is awesome.

For similar reasons I think arts and humanities students should take marketing and business courses.
