jchook··on OpenAI says it has evidence DeepSeek used its model to train competitor
Friendly reminder that China publishes twice as many AI papers as the US[1], and twice as many science and engineering papers as the US.

China leads the world in the most cited papers[2]. The US's share of the top 1% highly cited articles (HCA) has declined significantly since 2016 (1.91 to 1.66%), and the same has doubled in China since 2011 (0.66 to 1.28%)[3].

China also leads the world in the number of generative AI patents[4].

jchook··on TikTok goes dark in the US
Going for a tit-for-tat with China on censorship is so hypocritical for the US it undermines its entire global persona.

Yes, the tool snaps to I-frames when slicing. The `-c copy` flag ensures no re-encoding, and inherently limits cuts to keyframes.

TBH it's an unfortunate side-effect sometimes as you cannot cut video or audio exactly where you want.

Unreal. Land of Freedom bans Social Media app that runs on US servers, on its own terms, with censorship teams staffed by dozens of ex-US State officials[1].

Amazing that Congress will see bipartisan action on this issue before any of the other much more important issues.

It absolutely destroys criticisms of China banning Facebook, etc.

Most commonly I use ffmpeg to extract a slice of an audio or video file without re-encoding.

In case it interests folks, I made a tool called ffslice to do this: https://github.com/jchook/ffslice/

This is so cool.

In most contemporary games, you can occasionally see the mountains are hollow (from weird camera angles, clipping issues, etc).

However, with this method, your mountains are solid >:)

jchook··on Could the Soviet Union have survived?
Google the perspective of the people-- polls. It's not "hugely beneficial" as you claim.

NATO bombed the shit out Yugoslavia shortly after, one part of the world that remained communist.

Virtually every remaining communist country was bombed into oblivion or subject to suffocating sanctions.

jchook··on Could the Soviet Union have survived?
From any realistic humanitarian perspective, the fall of the Soviet Union was a horrific crisis that resulted in untold amounts of human suffering and poverty. Russia spiraled into a terrible mess, celebrated by the West.

Perhaps worth noting, shortly after the fall around 1991, Yeltsin hijacked the Russian government and prevented Communists from retaking power. The pattern of events immediately after the fall (and their strong support from the West) raises an eyebrow about how exactly the "collapse" was precipitated.

Yeltsin used self-anointed emergency powers to abolish the Constitutional Court and dissolve parliament. When the people protested, he ordered a military attack on parliament, killing hundreds and jailing hundreds of protesters.

Yeltsin seized control of all broadcast media, banned opposition publications, and permanently outlawed 15 political parties. He ordered assassinations of his political opponents, parliamentary deputies, and journalists.

Yeltsin illegally dissolved the Russian constitution and replaced it with one that gave himself nearly absolute power over policy.

By 1996, he was losing badly in his bid for re-election. A communist candidate was far in the lead.

During re-election, his administration was bankrolled to the tune of $10B by the IMF and World Bank. Even so, he was still trailing the communist candidate by a long shot. So, he threatened civil war, making it clear he would not relinquish power. About half of the country thought there would be a civil war if the communists won. Ultimately, he rigged the vote count, as reported by ABC news in the US.

When he won re-election, Bill Clinton famously lauded the event, saying Russia has "turned its back on tyranny".

jchook··on Sequin: A powerful little tool for inspecting ANSI escape sequences
Isn't it true that ANSI sequences can vary depending on the terminal emulator? Does this program account for that somehow?

In my shell scripts I often use `tput bold` etc instead of hardcoding the sequences.

jchook··on DeepSeek v2.5 – open-source LLM comparable to GPT-4, but 95% less expensive
I updated the title to say GPT-4, but I believe the quality is still surprisingly close to 4o.

On HumanEval, I see 90.2 for GPT-4o and 89.0 for DeepSeek v2.5.

jchook··on Drowning in Slop. It's clogging the internet with AI garbage
Archive link: https://archive.is/KVsRP

> In June, researchers published a study that concluded that one-tenth of the academic papers they examined “were processed with LLMs,” calling into question not just those individual papers but whole networks of citation and reference on which scientific knowledge relies.

> “I don’t think anyone has reliable information about post-2021 language usage by humans,” Speer wrote.

> Derek Sullivan, a cataloguer at a public-library system in Pennsylvania, told me that AI-generated books had begun to cross his desk regularly. Though he first noticed the problem thanks to a recipe book by a nonexistent author that featured “a meal plan that told you to eat straight marinara sauce for lunch,” the slop books he sees often cover highly consequential subjects like living with fibromyalgia or raising children with ADHD.

jchook··on Why wordfreq will not be updated
If it is (apparently) easy for humans to tell when content is AI-generated slop, then it should be possible to develop an AI to distinguish human-created content.

As mentioned, we have heuristics like frequency of the word "delve", and simple techniques such as measuring perplexity. I'd like to see a GAN style approach to this problem. It could potentially help improve the "humanness" of AI-generated content.
