spullara··on I rewrote PostHog's SQL parser, 70x faster, while barely looking at the code
that is vibecoding these days
spullara··on Genuinely, my all-time favourite image: Mamenchisaurus hochuanensis
the sauropod would strip whole branches at a time, not bite the leaves off.
spullara··on Job application asked for my SAT scores
SAT isn't an IQ test but IQ is very correlated with SAT scores.

sadly my kids were just recently taught cursive in elementary school for some unknown reason
spullara··on Anthropic employees accuse Trump administration of targeting them
Anthropic declares: "Mythos is too dangerous too release to the public" Proceeds to release Mythos plus safety guardrails as Fable. Amazon removes guardrails from Fable, getting access to Mythos. Government takes Anthropic's word for it and tells them to pull it until the guardrails can't be removed. They refuse. Government forces them.
spullara··on Specs Augmented Reality Glasses
they are expensive enough that they might be useful
spullara··on San Francisco Weighs PG&E Takeover Amid Soaring Utility Costs
Yep, that is the correct calculation for the max output.
spullara··on San Francisco Weighs PG&E Takeover Amid Soaring Utility Costs
It generates ~1 TWh per year or about 20% of SFs power. Power generation capacity is always in watts but it also doesn't run at 100% all the time.
spullara··on Ask HN: Has anyone replaced Claude/GPT with a local model for daily coding?
This is the only setup that I think is reasonable to use locally right now. I had an agent set it up for me from this guys recipe:

One thing I did change was the context length to 256k rather than 64k.

spullara··on Apple decided not to roll out Siri in EU after denied request for exemption
The 3rd party firm is the one that wants the data. No need for someone to steal it from them.
spullara··on Apple decided not to roll out Siri in EU after denied request for exemption
I am perfectly ok with EU having different rules of their own but they also can't be upset when features aren't offered there. That is the trade-off they have chosen and I am ok with it.
spullara··on Apple decided not to roll out Siri in EU after denied request for exemption
Personally, I wouldn't want Apple to comply with this EU law and I hope that more companies refuse to release features with onerous requirements. Opening up all access to control the phone to some random app the consumer installed seems super dangerous.
spullara··on India's surprise baby bust
oops! yes, per 1k.
spullara··on India's surprise baby bust
This is already happening in Japan where they are garbage collecting and consolidating them.
spullara··on India's surprise baby bust
There are so many factors. I think the biggest one is that the developed world looked at women and said "hey, they are just as smart and capable as men and if they work at companies we have 2x the workers" which is obviously true but what it leads to is a DINK society - and it locks you in. It is just much, much harder to raise children when both parents work and they don't live near their parents and other familial support. Add that into your observation that the world is more fun and selfish and it multiplies.

A lot of the decrease is also correlated with access to birth control which drastically reduced accidental pregnancies which were a decent amount of the fertility rate. Then we attacked teenage pregnancy with a vengeance. In 1957 it was 96/100k teen women had babies, 62/100k in 1991 and now down to the current rate of 11/100k. The postponement of births expands the time between generations which compounds the problem. An 18 yr old could have a baby that has a baby at 18 before a 36+ year old mom has their first child.

All this leads to exponential decay of humanity. In the near term we don't have to worry about extinction but we do have to worry about the pyramid schemes we have to support non-workers (like social security). This will all play out much sooner in Asia where the TFRs can be half of the US/EU. Imagine due to China's one child policy a young working person will soon have to support 2 parents and 4 grandparents somehow. There will be some kind of reckoning and some of the speculation around what it will look like is quite grim.

spullara··on MacBook Neo is so popular that Apple doubled production
which is crazy since the Mac has no problem running all kinds of old x86 junk
spullara··on Nvidia RTX Spark
definitely! it has the advantage that it can run CUDA kernels but on the other hand it has lower memory bandwidth and probably loses a token/s fight for many LLMs.
spullara··on The newest Instagram “exploit” is the goofiest I've seen
honestly I can't think of a better solution that would require a far more coordinated attack to pull off. it should work on any system where trusted folks are likely to have accounts.
spullara··on The newest Instagram “exploit” is the goofiest I've seen
for a while facebook had the ability to recover your account by having them ask several of your friends if the recovery was legitimate but it was turned off. my guess is that not enough people added trusted contacts to bother running it.

spullara··on The newest Instagram “exploit” is the goofiest I've seen
the alternative is people losing their accounts and people aren't willing to allow that. i do think that apple does this a little better where they try everything to contact you in every way they know and it takes a week to get access. at a minimum to change your email it should require a week of waiting to see if the user can access the original mail to the hand off.
spullara··on The newest Instagram “exploit” is the goofiest I've seen
recovery is always the weakest link in any authentication system
spullara··on YouTube to automatically label AI-generated videos
A friend of mine who is a very non-technical dermatologist listens exclusively to Suno songs she made. All in genres and styles of songs from her era, the 80s and 90s. Who else is going to make new songs for her? New music almost always targets young people.
spullara··on Project Glasswing: An Initial Update
I'm going to code myself up a new minivan.
spullara··on Magic the Gathering format: Fun 40
The best version of MTG for experts is Mental Magic. The only thing you keep track of is the number of cards in your hand and how many lands you have in play. A card gets its identity when you play it. You can play it in a car with no board!
spullara··on United Wizards of the Coast
since some of their gripes are "use ai" and "rto" I don't think we are talking about a sweatshop.
spullara··on United Wizards of the Coast
I am skeptical there is any customer benefit from unionization and it makes me concerned that MTG Arena might not be around for long term. As a big customer, I am worried about my investment in the platform with this announcement. MTGO still exists, I wish it had a better client.
spullara··on Show HN: OSS Agent I built topped the TerminalBench on Gemini-3-flash-preview
"rewrite all subtrees that match this pattern" works really well in jetbrains, they call it structure search-and-replace.
spullara··on Over-editing refers to a model modifying code beyond what is necessary
this is one of the best things about using claude over gpt. claude understands the bigger assignment and does all the work and sometimes more than necessary but for me it beats the alternative.
spullara··on Lean proved this program correct; then I found a bug
Meaning it has no episodic memory of any of those analyses that it has done.
spullara··on Lean proved this program correct; then I found a bug
claude making a statement that sounds impressive but it is actually the first codebase it has ever analyzed.

"This is genuinely one of the most memory-safe codebases I've analyzed."
