lz400··on The worst job interview I ever had
Truth is, most people who interview people have no idea how to do it. I know because I've done hundreds and nobody ever trained me or explained to me how to do it properly. Over the years I've seen so many people on both sides of the table that I developed a method and I got semi-functional at it but so many people doing interviews shouldn't that bad experiences should be almost expected by now.
lz400··on SpaceX S-1
Even if we consider what they pay for colossus high (I've no idea, I haven't looked at the numbers), wouldn't this a bit be different from "investing in infrastructure"? They're not building the DC themselves, they're just renting, they can scale down to 0 anytime and not have pressure to recover costs, they don't have debt on the HW, etc.
lz400··on Map of Metal
Reminds me of the Ishkur's guide to electronic music

https://music.ishkur.com/

Both these maps of styles have most of their richness in the past. Modern era is mostly stagnation. I suppose it would be different if I had a map of hip-hop?

lz400··on Who will buy your services if you fire us all?
I feel there are like 50 load bearing assumptions in this piece of fiction that are dubious at best, definitely speculation. When you put all of them together and chain them in a product of probabilities it becomes tech bro wish fulfilling fantasy. But as usual this is expressed with total confidence and inevitability. This is a perfect encapsulation of all that is wrong with rationalists, TPOT, etc. IMHO.

I'll just suggest that you track your predictions and "update your priors" once they start domino falling.

lz400··on Someone Shared a Real Monet Painting as AI and Asked for Critiques
It could be the painting is real and those comments were written by AI
lz400··on Spain's parliament will act against massive IP blockages by LaLiga
About time, this was crazy and should result in some action against cloudflare for allowing it
lz400··on Ask HN: Who is using OpenClaw?
I use claude code everyday. Most of my friend circle have a CC max subscription and we talk about and use AI all the time. Not a single one has installed openclaw yet.

For me personally I don't see that it can do a lot of things that CC/codex doesn't do and that _I_ want to do. Also I'm concerned about security.

For a while I wanted some agent I could tell what to do in my PC at home from my phone, so I just vibe coded a web site that can start CC and I used tailscale to secure it.

lz400··on The Rise of the Em-Dash in Hacker News Comments
I just learnt that em dash in a mac is option+shift+hyphen. I hadn't realized it was so difficult and inconvenient, and in the end it looks so similar to the other one: — -. Thin value. It's no surprise humans barely use them. Then why did it get picked up so much by AIs? I'd have imagined it's not in a lot of training data. Print media practices I guess?
lz400··on How to effectively write quality code with AI
Top 200 that work partially in public. A good example is Mitchell Hashimoto. Works open source, uses AI a lot and writes about it. Next gen AI will learn from the lessons people like him share
lz400··on How to effectively write quality code with AI
I mean, having a curated dataset of the works and posts of the top 200 coders in the world (at least the public ones) is not very difficult. I’m sure these articles like the one in OP will be very easy to mark as “high value training data”. I think you’re letting your bias blind you
lz400··on How to effectively write quality code with AI
>Hmm... How will it filter out those by the dumbest coders in the world?

if you know, and I know, and the guys at openai and anthropic know... not a big leap that the models will know too? many datasets are curated and labeled by humans

lz400··on How to effectively write quality code with AI
The best thing about this is that AI bots will read, train on and digest the million "how to write with AI" posts that are being written right now by some of the smartest coders in the world and the next gen AI will incorporate all of this, making them ironically unnecessary.
lz400··on Apple to soon take up to 30% cut from all Patreon creators in iOS app
Makes me think of the concept of involution in Chinese business and how they understand all of this very differently, and how difficult it is to compete because of that.
lz400··on Why DuckDB is my first choice for data processing
I do a lot of data processing and my tool of choice is polars. It's blazing fast and has (like pandas) a lot of very useful functions that aren't in SQL or are awkward to emulate in SQL. I can also just do Python functions if I want something that's not offered.

Please sell DuckDB to me. I don't know it very well but my (possibly wrong) intuition is that even giving equal performance, it's going to drop me to the awkwardness of SQL for data processing.

lz400··on What is the nicest thing a stranger has ever done for you?
This is not to me but a friend of mine was climbing Mt Fuji in _winter_ (this is a serious thing you need to be prepared for, alpine climbing with lots of snow and ice) when he slipped and started sliding down the mountain out of control.

When he was about to fall to his death a father and son that happened to be there in a struck of luck managed to grab him and save his life. My friend had banged a few rocks in the way down so his leg was fractured and they had to help him down for hours.

They saved his life and risk theirs to ensure he had the best chance. They visited my friend in the hospital where he was grateful and teary eyed. And then the father and son asked him for money, straight up. My friend of course agreed on an amount to them, all in all, he didn't know how to repay them anyway and this was oddly simple. I found everything heroic and strange at the same time but a good story.

lz400··on IBM to acquire Confluent
I have similar stories, I showed the Confluent consultants a projection of their Kafka quote vs Kinesis and it was like 10x, even they were confused. The ingress/egress costs are insane. I think they just do very deep discounts to certain customers. The product is good but if you pay full ticket it probably doesn't make sense.
lz400··on Crypto hoarders dump tokens as shares tumble
If you see the bitcoin charts, price has gone up a lot in the last few years but volume has tanked. Do I read this right that now crypto is basically a smaller market where a bunch of whales scam a ever dwindling but never completely disappearing flow of fools and marks?
lz400··on Tesla's European sales tumble nearly 50% in October
What would it take to reconnect there? evidence that FSD and robots are vaporware?
lz400··on The Case That A.I. Is Thinking
It would be funny if what you get from a read only human brain is a sort of memento guy who has no capacity to remember anything or follow a conversation... kind of like an LLM!
lz400··on The Case That A.I. Is Thinking
I'm not an expert but as far I understand, plasticity is central to most complex operations of the brain and is likely to be involved in anything more complex than instinctive reactions. I'm happy to be corrected but it is my understanding that if you're thinking for a while on the same problem and establishing chains of reasoning, you are creating new connections and to me that means it's fundamental in the process of thinking.
lz400··on The Case That A.I. Is Thinking
I mean, _we_ probably can't think with our wetware on a read-only substrate. It doesn't establish it as essential, just that the only sure example in nature of thought doesn't work that way.
lz400··on The Case That A.I. Is Thinking
>If we took your brain and perfectly digitized it on read-only hardware, would you expect to still “think”?

it wouldn't work probably, brains constantly alter themselves by forming new connections. Learning is inseparable from our intelligence.

lz400··on How OpenAI uses complex and circular deals to fuel its multibillion-dollar rise
Even if/when the bubble pops, I don't think NVIDIA is even close to need rescuing or being in trouble. They might end being worth 2 trillion instead of 5 but they're still selling GPUs nobody else knows how to make that power one of the most important technologies in the world. Also, all their other divisions.

The .com bubble didn't stop the internet or e-commerce, they still won, revolutioned everything, etc. etc. Just because there's a bubble it doesn't mean AI won't be successful. It will be, almost for sure. We've all used it, it's truly useful and transformative. Let's not miss the forest for the trees.

lz400··on Public Montessori programs strengthen learning outcomes at lower costs: study
Very interesting story. If I may ask, looking back, do you blame Montessori for the “lack of real world preparation” or do you think rather that it was the regular school that had a bad system and you were in a better one and should have stayed there? If you had stayed there until uni do you think you’d adapted well to higher edu?
lz400··on Public Montessori programs strengthen learning outcomes at lower costs: study
I want to offer a different data point. I took my daughter to a Montessori-adjacent school for 3 years. It's not Montessori exactly and they didn't advertise as such but they had a different European name attached to it that is downstream from Montessori. They had multi-age education, stressed in children directed learning and individual growth, they didn't have exams, etc.

I changed my daughter this year and overall I'm disappointed in that school. There were many issues but the most important ones to me where:

- No exams, only individual growth meant there's no guarantee the kid is learning at a good pace. When I worked with her at home I could easily identify many gaps and deficiencies. She's now struggling a bit in her new school because of this but I think it will resolve soon.

- Because they didn't like comparing kids to standards or among each other the feedback I received was useless. It was always "she's doing excellent, we see strong growth" but it wasn't true.

- The school rejected most parent feedback and issues raised with something "maybe this style of education is not for you". For example, I know of a few other kids that had to leave because the school didn't take action against bullying because they didn't believe in punishments, etc.

I have to say there were good things too, in particular my daughter really enjoyed it there and formed strong bonds with other kids. I think in general it was ok for elementary education but I strongly think it's not after that and I now have a perhaps unjust bias against Montessori and derivatives.

lz400··on What Americans die from vs. what the news reports on
That's not correct. It counts the total number of school shootings. Some of those shootings had no victims. The total of students shot is also provided with some more elaboration with charts here.

https://www.abc.net.au/news/2024-12-17/us-school-shootings-2...

As you can see your number of 13 makes no sense, there were 200-300 students shot (!)

lz400··on What Americans die from vs. what the news reports on
I think there are actually more school shootings than mass shootings because mass requires ~4 victims and school doesn't. There were ~330 shootings in 2024. 70 people died. 200 wounded.

https://www.abc.net.au/news/2024-12-17/us-school-shootings-2...

lz400··on What Americans die from vs. what the news reports on
>School shootings in 2024 dipped slightly from the year before, but the 330 school shootings recorded last year still mark the second-highest number since 1966

lz400··on What Americans die from vs. what the news reports on
You guys had a shooting last year, but school shootings in the US average to ~1 per day
