Reflections on 2 years of CPython's JIT Compiler

Reflections on 2 years of CPython’s JIT Compiler: The good, the bad, the ugly 5 July 2025 This blog post includes my honest opinions on the CPython JIT. What I think we did well, what I think we could have done better. I’ll also do some brief qualititative analysis. I’ve been working on CPython’s JIT compiler since before the very start. I don’t know how long that is at this point … 2.5, maybe almost 3 years? Anyways, I’m primarily responsible for Python’s JIT compiler’s optimizer. Note that

Can an email go 500 miles in 2025?

news.ycombinator.com Unknown 2025-08-14 12:49:27

Once upon a time, there was a university president who couldn’t send an email more than 500 miles, and the wise sysadmin said that’s not possible, so the president said come to my office, and lo and behold, the emails stopped before going 500 miles. Has technology improved? Can we send an email farther than 500 miles in 2025? There’s a lot to the story that’s obviously made up, but if we fix the details so that it can happen, we can reproduce it. connect We need some code to do a nonblocking

Corrected UTF-8 (2022)

news.ycombinator.com Unknown 2025-08-18 01:29:26

UTF-8 is decent and all but it contains some design errors, partly because its original designers just messed up, and partly because of ISO and Unicode Consortium internal politics. We’re probably going to be using it forever so it would be good to correct these design errors before they get any more entrenched than they already have. Corrected UTF-8 is almost the same as UTF-8. We make only three changes: overlength encodings become impossible instead of just forbidden; the C1 controls and the

Journalists Just Roasted Sam Altman To His Face

OpenAI CEO Sam Altman got a taste of his own medicine when he went on the New York Times' turf and tried to twist the newspaper's copyright lawsuit against it. As flagged by PG Gamer, the live recording of the NYT's "Hard Fork" podcast — hosted by journalists Kevin Roose and Casey Newton, and featuring as guests Altman and OpenAI's chief operating officer Brad Lightcap — was testy from its start. Almost immediately upon sitting down on the "Hard Fork" stage, the CEO came out punching. "Are yo

Mysterious Object Headed Into Our Solar System Is Coming From the Center of the Galaxy

Folks, it's official: the object that astronomers recently spotted blowing through the outer solar system came from interstellar space. Yesterday, the intriguing stranger was named A11pl3Z. Now, it's earned the esteemed designation 3I/ATLAS — that "I" standing for "interstellar." 3I/ATLAS is currently located between the orbits of the asteroid belt and Jupiter, the New York Times reports, where it's about 416 million miles away from the Sun, NASA said.

Pluto is largely compatible with Lua 5.4 source code, but there is an imperfection: Pluto implements new keywords, which can cause conflicts with otherwise normal identifiers such as 'switch', or 'class'.

End of an Era

news.ycombinator.com Chris Crawford 2025-08-30 20:17:11

I recall saying to one of my colleagues at Atari way back in 1982 that I wanted to make a game that would be genuine art. A year later I built a game that was my first experiment in that direction: Gossip. It was a ridiculously simple game in which a player attempted to win favor in a group by calling people and telling them how much you liked or disliked some third party. The underlying concept was that “people like people who like people they like.” For some reason, many players had problems a

In 2012, I created Jedi—a Python auto-completion library that eventually reached millions of users and billions of downloads. But as the ecosystem evolved, one limitation became clear: speed. Jedi’s architecture couldn’t deliver the performance needed for large-scale projects. In 2020, I started over—with everything I’d learned—building ZubanLS from the ground up in Rust.

So I gave it a quick spin Setup The setup is much simpler than I remember it, you can use uv for it now. uv pip install modular --index-url https://dl.modular.com/public/nightly/python/simple/ After that you can declare a .mojo file that looks like this: # mojo_module.mojo from python import

Gigabyte Radeon RX 9060 XT Review: Great Value Gaming

It's AMD's turn. After months of $2,000+ GPUs and long discussions of DLSS, we're finally on the red team's turf. AMD's strength historically lies at the budget end of the spectrum, where the majority of gamers are playing at 1080p, and spending $1,000 or less for their entire system. Even though we really recommend splurging on a GPU, that's just not the reality for most folks. An $800 GPU needs $1,200 in other parts, and at that point most people who aren't into PC gaming will start shopping
