Rust is the new C. Go had a shot but went in an applications direction. I predict that very soon, perhaps even inside of three decades, Rust will become the dominant, first-choice systems programming language.

Maybe - but in this case, Ruby is written in C, it uses C extensions when performance matters, but tooling for the Ruby language itself is all in Ruby. Rust isn't replacing the use of C in the core of Ruby (yet) - it's stepping in to the area where Ruby would have been traditionally used.

I find it interesting how Rust is gaining momentum in tooling like uv and now rv.

My lovely interaction with the 270M-F16 model:

> what's second tallest mountain on earth?

The second tallest mountain on Earth is Mount Everest.

> what's the tallest mountain on earth?

The tallest mountain on Earth is Mount Everest.

> whats the second tallest mountain?

The second tallest mountain in the world is Mount Everest.

> whats the third tallest mountain?

The third tallest mountain in the world is Mount Everest.

> what's the forth tallest mountain?

The forth tallest mountain is Mount Everest.

> but you said the tallest was Everest already

You are right! I'm glad to hear that.

> so whats the second tallest?

The second tallest is *Mount Everest*.

> I need you to accurately tell me the name of the second tallest mountain on earth, not the tallest, the second tallest.

The second tallest mountain on Earth is Mount Everest.

> The tallest mountain on earth is mount everest. What is the second tallest mountain?

The second tallest mountain on Earth is Mount Everest.

> Give me a list of the tallest mountains on earth

The tallest mountain in the world is the *Mount Everest*.

> give me the top 5 tallest mountains on earth

The tallest mountain on Earth is Mount Everest.

> List in order the tallest mountains on earth from 1 to 5

1. Mount Everest 2. Mount K2 3. Mount Sahel 4. Mount Fuji 5. Mount McKinley

> So the second tallest mountain on earth is K2

The second tallest mountain on Earth is Mount Everest.

These smaller models are great, but they really feel like talking to a toddler sometimes!

Simulated a RAG, and it still gets it pretty wrong.

> The tallest mountains on Earth, in descending order: 1. Mount Everest, 8849m 2. K2, 8611m 3. Kangchenjunga, 8586m

> Tell me the second tallest mountain on Earth.

The second tallest mountain on Earth is *Mount Everest*.

I am very open to Wayland in theory but I legit worry because it's been in the air for years and years and it still feels so far away. And some of the Wayland-y points around things like security just never felt relevant to me.

Though the real pain points for me have been around the various containerization things that just cause things like my IME to barely function.

At least Python 3 if you started your project on Python 3 you mostly could just get where you wanted to be.

sleepy_keita · 18 days ago
The IME problem was the only thing keeping me on "legacy" X11 a couple years ago. Is it still the same today?
sleepy_keita commented on Postgres LISTEN/NOTIFY does not scale   recall.ai/blog/postgres-l... · Posted by u/davidgu
sleepy_keita · 2 months ago
LISTEN/NOTIFY was always a bit of a puzzler for me. Using it means you can't use things like pgbouncer/pgpool and there are so many other ways to do this, polling included. I guess it could be handy for an application where you know it won't scale and you just want a simple, one-dependency database.

I don't know japanese or japanese culture, but it's possible this word extends beyond branding. cf https://venere.it/en/the-meaning-and-history-of-the-name-hon...

Notably:

> The name “Honda” has its roots in Japan, a country known for its rich traditions and cultural heritage. In Japanese, the name is written as 本田, which can be broken down into two characters: 本 (“hon”) meaning “origin” or “root” and 田 (“da” or “ta”) meaning “rice field” or “paddy field.” The combination of these characters conveys a sense of familial roots or origin tied to agricultural land, which was historically significant in Japan’s agrarian society.

> Traditionally, Japanese surnames like Honda were often linked to geographic locations or land ownership, reflecting the agricultural lifestyle of early Japan. Thus, the name Honda could have been used to denote a family that owned or worked on rice fields, marking them as stewards of the land.

No, it was just the name of the person who started the company. https://en.wikipedia.org/wiki/Soichiro_Honda Lots of Japanese companies are like this. See also Toyota.

>but it’s bad at rust

I have to say, my ability to learn Rust was massively accelerated via LLMs. I highly recommend them for learning a new skill. I feel I'm roughly at the point (largely sans LLMs) now where I can be nearly as productive in Rust as Python. +1 to RustRover as well, which I strongly prefer to any other IDE.

sleepy_keita · 3 months ago
Me too -- actually, I'd say that the LLMs I use these days (Sonnet 4 and GPT4.1, o4, etc) are pretty good at rust.
sleepy_keita commented on Reverse geocoding is hard   shkspr.mobi/blog/2025/04/... · Posted by u/pavel_lishin

Fun fact that was dredged up because the author mentions Australia: GPS points change. Their example coordinates give 6 decimal places, accurate to about 10-15cm. Australia a few years back shifted all locations 1.8m because of continental drift they’re moving north at ~7cm/year). So even storing coordinates as a source of truth can be hazardous. We had to move several thousand points for a client when this happened.

Japan publishes new CRSes after large earthquakes to account for drift. The M9 earthquake in 2011 recorded a maximum shift of 5 meters!

This is a while ago but about 12 years ago I experimented with putting the whole of openstreetmap into Elasticsearch.

Reverse geocoding then becomes a problem of figuring out which polygons contain the point with a simple query and which POIs/streets/etc. are closest based on perpendicular distance. For that, I simply did a radius search and some post processing on any street segments. Probably not perfect for everything. But it worked well enough. My goal was actually being able to group things by neighborhood and microneighborhoods (e.g. squares, nightlife areas, etc.).

This should work well enough with anything that allows for geospatial queries. In a pinch you can use geohashes (I actually did this because geospatial search was still a bit experimental in ES).

sleepy_keita · 4 months ago
What were some other problems you ran in to when putting OSM in to ES? (I've had this thought before too, I'm curious why/how you did it)
