richrichie··on Static search trees: faster than binary search
Go and C++ have pretty decent standard libraries, for example.
richrichie··on Static search trees: faster than binary search
Rust is great for pet projects. Otherwise, it is a big security risk for large commercial projects, since it lacks a useful standard library and any non trivial program needs to download a thousand crates to work.
richrichie··on I was wrong about the ethics crisis
He had everything against him - media, law enforcement, justice system, big tech, social media. They even tried to kill him twice and he still won.

So it was a big in your face landslide. Cope.

I am sorry to say that the elections in Russia are more reliable than that in the US, where they take a month to count.

richrichie··on Elon Musk Is a National Security Risk
So Elon’s mistake was he had meetings with heads of states like every other multinational corp CEO?
richrichie··on I was wrong about the ethics crisis
Indeed he is an elected head of state. Cope.

You understand “if any”?
richrichie··on I was wrong about the ethics crisis
Is that why people overwhelmingly voted for change in 2024, ironically to bring back the “dictator”? Popular mandate, all of swing states, majority of governorships, house and the senate - seems as decisive a democratic choice as it can get!

> In fact, our current climate crisis is a demonstrated market failure.

This wrong on so many levels. There is neither a climate crisis nor a market failure. If any, central economies exhibited (and exhibit) higher levels of pollution and destruction of public good.

Mindless repetition of the climate crisis trope has done more damage to the cause than carbon emissions.

richrichie··on In praise of the hundred page idea
Natsume Soseki once said that reading every book from cover to cover is like marrying every girl you fall in love with. I think it was in the book Kusamakura.

A physicist friend of mine changed my life by simply saying that the reader is under no obligation to or has a contract with the author that he needs to read everything the author wrote. I cam across the more poetic Soseki later.

richrichie··on The One Hundred Pages Strategy
This is like 50 push-ups a day etc. Nice, easy to remember round number and very simple instruction. For many people consistency of any sort helps and simple rules are far more effective.

Quality of life for the average man now is way better than it was at any time in history. A fact.
richrichie··on New Data Reveal Climate Change-Driven Insurance Crisis Is Spreading
If we had rational cost-benefit discussion instead of alarmist fear mongering, we would not have this problem.

richrichie··on U.S. Navy Shoots Down Own Plane as Fresh Strikes Target Houthi Rebels in Yemen
There is a theory that Navy is running cover to hide the fact that Houthis shot it down. Houthis have downed a few Reapers this year alone.

They are not wrong. Do you know any mechanism other than markets that work at scale and that don’t cost a bomb and don’t involve abusive central authority?
richrichie··on Show HN: NoSQL, but it's SQLite
Doesn’t sqlite-utils does this and more, better?
richrichie··on School smartphone ban results in better sleep and improved mood: study
Theoretically yes. In practice it is extremely difficult to say no to the short dopamine shots that a smart phone can deliver. Perhaps, comparable how alcoholics struggle to drink moderately.
richrichie··on Unlocking the power of time-series data with multimodal models
Perhaps, Renaissance has been doing this all along. Just that they had data and compute in times (80s and 90s) when most have not heard of these things.

In the end, one needs a small edge and thousands of low correlated trades to take advantage of LLN.

richrichie··on Unlocking the power of time-series data with multimodal models
Kelly et al took similar approach to trading. The idea was that human traders looked at charts on the screen and “intuitively” made trading decisions.

richrichie··on How to Study Mathematics (2017)
The biggest obstacle for me was (and is) fear or failure when it comes to solving exercises.

richrichie··on Central bankers can be too independent
Perhaps you do not understand the difference between relative prices and nominal price level. So it is natural to extrapolate that way.

PS Almost all manufacturing is done indoors now. Rain does not affect supply of most manufacturing of iphones, trousers, ovens, etc.

Muddled thinking? John is as clear as they come in econ. I have been a consumer of his writing since grad school (Asset Pricing is a standard text every econ/fin phd reads).

richrichie··on The Engagement Is Better on Bluesky
I saw a recent CNN report which claimed that political orientation on X is roughly even now, compared to pre Musk version (which was about 70 left, 30 right). That might appear right wing twitter for people used to the left wing bias (unknowingly).

Not sure what the ratio is on BS, but it appears worse than old twitter. That would distort comparisons with X.

richrichie··on 'Shallow' sports and 'deep' social hierarchies
Such customs are still around and are proudly followed in places like military especially the Navy.

Common wealth navies still have ceremonial dinners which cater to the attendance of the Queen (or King now). There is a whole lot of intricacies that goes on there.

richrichie··on AI Data Centers May Consume More Electricity Than Entire Cities
The majority of comments seem to imply that if the future utility is uncertain or unknown, it is OK to disregard climate change implications.

HN discourse typically treats climate change as a non-negotiable absolutist issue.

Tech (understandably?), as opposed to auto, has a special carve out?

> BTC, which is designed to not be able to scale even as far as just serving the transactions of people eating lunch in Berlin.

BTC’s counterparts are treasury bonds and gold. Not cash. Many non-econ background tech people misunderstand the difference. Try buying lunch with gold or treasury bond.

richrichie··on Z-Library Helps Students to Overcome Academic Poverty, Study Finds
> “Living in a 3rd world country, 1 book would cost like 50%- 80% already of my daily wage,” one Redditor wrote.

Typical technical books are priced at upwards of $50. $100 a day is not poor by any means in 3rd world countries.

There is a whole book on this topic. I think it is called Street Coder.
