What are you talking about? The article doesn't say no one made a movie about him.

There are at least three Chinese movies and a TV series about him.

Hot damn, fed it part of an unpublished blog post I wrote, and it got me immediately.

I'm not famous or anything. I've written some academic papers and had a couple blog posts trend on HN, which are surely in the training set.

It was able to identify me based on my style (at least according to its explanation). The way I approached the topic and some of the notation I used point to a particular academic lineage, and the general style reflected my previous blog posts.

That said, I gave it part of an (unpublished) personal essay, and it had no idea. But I have no writing in that style that's published, so it makes sense. Still impressed.

Re:Aircraft Detection at Planetary Scale on Monday March 24, 2025 @06:30PM (#43466064)
It's not at all comparable. ADS-B is opt-in: you place an ADS-B out transmitter in your plane and turn it on to transmit your position [1]. You're perfectly free to turn your ADS-B off if you like. It's not even required for most of the US, so some planes may not have it installed (ADS-B out is only required within 30 nautical miles of a Class B airport [big airport], inside Class C airspace [medium-size airport], or in Class A airspace [18,000 ft above sea level]).

Military aircraft don't use ADS-B out a lot of the time. Spy planes are obviously not going to transmit their locations. A civilian plane with an electrical failure might stop transmitting ADS-B out. Being able to identify planes via satellite is a whole separate capability.

[1] In all the planes I've flown, ADS-B is configured to transmit whenever the master electrical switch is turned on, but it can be configured to be turned on and off at will. See this video on a mid-air collision involving an eccentric character who liked to fly with ADS-B out turned off: https://youtu.be/G5y3JiOEnVs?si=rs5gNMurZ9ssUloS. If I recall correctly, he had his ADS-B wired to his nav lights so he could turn it on and off at will.

People do these same sock puppet studies on Twitter/YouTube/etc. and find biases there as well. There's a lot of literature out there.

Here's a recent study on YouTube from the same author as this TikTok study finding left-leaning bias in US recommendations: https://academic.oup.com/pnasnexus/article/2/8/pgad264/72424....

Here's a somewhat older study from Twitter itself where they determined that their recommendations were biased toward right-leaning accounts: https://cdn.cms-twdigitalassets.com/content/dam/blog-twitter....

IMO the interesting question is not whether an individual platform is biased and what its biases are, but rather how we might regulate recommendations given that there is always a risk of bias.

I think this is a valid point and a really interesting question. If that's the standard, we need to regulate all recommendation algorithms. (i.e. put limits on Twitter, Instagram, and YouTube as well.)

How could we regulate this? I can think of two ways:

- Results-based enforcement. i.e., companies are free to use whatever recommendation model they like, but have to recommend content within ideological bounds. i.e., you can't bias toward one partisanship more than X%. There's some precedent for this with the equal-time rule (https://en.wikipedia.org/wiki/Equal-time_rule) and FCC fairness doctrine (https://en.wikipedia.org/wiki/Fairness_doctrine).

- Algorithm-based enforcement. i.e., there are limits on the algorithm itself. Perhaps you have to present your algorithm to a government agency and provide a proof that it obeys certain properties. But the enforcement here is analytical rather than empirical.

I think the key metric missing here is how long the user watches each video. Likes and replies are probably helpful too, but when I've used short-form video content apps like TikTok, Reels, and YouTube Shorts before, they've gotten a pretty good measure of me without me ever liking, replying, or following.

With the current methodology, the bot either watches the whole video, a fixed duration of it, or a random duration before swiping. The bot doesn't organically watch or swipe based on its interests like a human user would.

Perhaps I should have been more clear. It's TikTok, so of course the only way to collect recommendations is to watch videos. Some studies watch the whole video, some just watch part of it, but it's TikTok, so fundamentally you're watching a video.
It's another sock puppet study: https://arxiv.org/abs/2501.17831

Very similar methodology to an earlier study the government cited in their case against TikTok: https://networkcontagion.us/wp-content/uploads/NCRI-Report_-...

There are a number of issues with these studies, one being that the way the sock puppet bots interact with content is not exactly organic. Typically they search for content in a conditioning phase, followed by random scrolling during which the recommended videos are collected and classified by an LLM. Modern recommendation algorithms famously work by examining how long and how users engage with content, and there's none of that going on here. Still, the methodology itself and the use of LLMs to classify content is clever and probably about the best we can get.

Also, even if there _is_ a bias, it doesn't tell us why. Are the recommendations intentionally spiked, or is this simply the recommendation strategy that maximizes profit? (Or that the recommendation model thinks will maximize profit?) It's very difficult to tell, which is part of what makes these models dangerous and also part of what makes them difficult to regulate.

On a sidenote, TikTok (and presumably other content platforms) _really_ does not like these studies, as demonstrated by them nerfing search functionality after the second study above was released to prevent researchers using these techniques in the future. I haven't read the study in detail yet, but it will be interesting to see how the team at NYU Abu Dhabi adapted their methodology.

Re:Caltech's CS interview prep course on Sunday February 27, 2022 @04:18PM (#30492622)
Yeah, I'd say this is exactly what's going on at big tech companies. Add to that the need for an interview process that is very standardized for (1) scalability in a large company and (2) legal protection against discrimination (at least nominally), and it makes a load of sense.
Re:AI could end foreign-language subtitles on Wednesday January 19, 2022 @05:34PM (#30001371)
There's also the problem of content which doesn't have subtitles to begin with---YouTube's automatic subtitle generation is great, but could be improved and expanded to languages other than English.
Re:AI could end foreign-language subtitles on Wednesday January 19, 2022 @05:33PM (#30001352)
Yes! My perennial problem is that most Chinese TV content has excellent subtitles, but they're burned in to the videos. So if I want to watch a Chinese show with a friend who doesn't read Chinese, there's no option even for auto-translated subtitles. I've often thought of writing a script to generate subtitle files using text recognition, but haven't gotten around to it.

Shocker---you might be required to be vaccinated in order to live in a facility for ultra-sick kids, many of whom are immunocompromised. I guess that's an "insult to the Canadian anthem" somehow.

Re:Show HN: Clone your voice and speak a foreign language on Monday January 03, 2022 @07:44PM (#29789401)
Pretty interesting! I tried this both English -> French and French -> English.

English -> French seemed to work best, with the AI output have a very similar timbre to my real voice. Not hyperrealistic for me, but decent enough given I gave it a ~20s sample.

French -> English was less good in terms of the timbre and pitch of the voice---way higher than my real voice. It did have a bit of a Canadian accent, though, which is funny because I speak French with a Quebec accent. Maybe that's what I would sound like if I had a Canadian accent in English?

Unfortunately probably none, unless you live pretty far north. We're pretty close to the speed of light limit* when it comes to latency between the US and Asia, which makes sense as a straight line is over the Pacific anyway. (e.g., I get ~1.1x the theoretical min latency pinging Tokyo from my Fiber connection in the SF Bay Area)

Where it seems like we're pretty far from the theoretical min is connections within the continental US. Latency is pretty bad (e.g. I get like 1.5x - 4x the theoretical min latency from my Fiber connection in the SF Bay Area, depending on endpoint). I assume part of this is indirect connections (you don't have a direct fiber connection between every pair of cities, because that would be dumb) and some of it is routing overhead (a connection to Asia goes a long distance, but often has way fewer hops).

Note that this is theoretical min latency based on the speed of light through fiber*, which is a bit higher than (about 5/3x) the speed of light through air. New fiber optic tech might help this at some point.

Re:Steam bans all blockchain and NFT games on its platform on Friday October 15, 2021 @03:27PM (#28882026)
Considering all the crazy shit that goes down with CSGO skins, which have a much more controlled market than NFTs, I find this pretty unsurprising.

For anyone unfamiliar with the CSGO skins market and the explosion of illegal gambling sites a few years ago, I highly recommend this video [1].

There was an excellent article in Harpers about this a few months ago: https://harpers.org/archive/2021/04/lost-in-thought-psycholo...

I had no idea, but schizophrenic breaks and other psychological symptoms are not uncommon at meditation retreats, and staff are often untrained on how to deal with it.

Sorry this happened to you OP, and I hope you're able to get effective help.

+1 to the Toshiba CB-35 Chromebook. It is an excellent laptop fr running Linux, although a bit outdated at this point. If I hadn't shattered mine's screen in a bike crash, I probably would still be using it today.

Not sure what the best Chromebook is for running Linux, but appreciate the OP's suggestions.

Re:Raspberry Pi WiFi to ethernet bridge on Thursday June 10, 2021 @05:55PM (#27466317)
Yeah, this. I've used Ethernet bridge on old Netgear 802.11n routers, and it's quite fast.
1) It runs Linux, so you're limited to 0 A.D.

2) No, it has the extremely expensive server GPUs, so their drivers should be normal.

Dude it's just a bunch of GPUs with a fast network...

Re:Higher quality audio makes people sound smarter on Thursday April 15, 2021 @03:34PM (#26825143)
Not really. Zoom applies lots of noise canceling and other filters, so your raw audio doesn't correspond to what you actually sound like to other people (unless you use "original audio").
Re:Higher quality audio makes people sound smarter on Thursday April 15, 2021 @03:24PM (#26825023)
I think one of the things people often overlook is the distance between the mic and your mouth. The closer the mic is to the source, the higher the signal-to-noise ratio will be, so the less echo and background noise you'll get. Many smartphone mics will sound very impressive if you hold them around 6-12 inches from your mouth. But you don't really want to do this with your hand, so it's important to get a mic with a nice stand or a form factor that allows you to comfortably place it where you'll get good audio.

Another thing people forget about is the noise canceling and other filters that are applied to your audio by default. If you're in a reasonably quiet place, it's probably reasonable to put "noise canceling" in Zoom on low. This will make your audio less garbled. If you have a really solid audio setup with headphones, you should try turning on "use original sound," which can make your audio really nice (unfortunately not available in Linux).

I highly recommend Fifine's mics. They have a USB condenser mic with a boom arm for $60 (~$35 for just the mic) [1], and a lavalier (lapel) mic for $20 [2]. The audio quality is really quite impressive.

Re:Higher quality audio makes people sound smarter on Thursday April 15, 2021 @03:11PM (#26824887)
I was lucky enough to realize, a month into the pandemic, that I would be having all meetings on Zoom for at least 3-4 months. I did three things, which seemed a little excessive at the time, but turned out to be great investments, since I've been working for home for over a year since then.

1) I bought a reasonably nice Logitech C920 Webcam. At the time, it was a $100 on AliExpress, which seemed like a crazy markup over the MSRP of $70. This turned out to be a great investment, given how much higher the prices went. Most people will probably still be working from home for at least 3-5 months, and you can buy one now for $70!

2) I bought a cheap USB condenser mic with a boom arm. This was a $70 package deal, and from a cheap Chinese brand Fifine, but the audio quality is truly amazing, and having the mic close to your mouth makes a huge difference. Probably my best investment. Seriously. Go buy a podcast mic and a boom arm. Now. If you want something more portable, the same company also makes very decent lavalier mics (lapel mics) for ~$20. Those are more omnidirectional, so they pick up more background noise than condenser mics, but they are imminently more portable.

3) I wired my bedroom with Ethernet. This was a bit of a hassle, since I had to run the cable down the side of the house and then underneath, and it also required crimping my own cables. However, it was totally worth it, since I knew connection issues were never my problem. I don't understand how other people suffer through constant drops over WiFi. I guess they're just accustomed to dealing with it, and don't think of switching to Ethernet as an option.

Re:US agencies call for pause in Johnson & Johnson vaccine on Tuesday April 13, 2021 @06:06PM (#26799957)
Depends on the particular trial, but the clinical trial data used to get FDA approval usually measures symptomatic cases, which is a combination of coronavirus symptoms and positive PCR test.

There's some additional data which indicates Pfizer and Moderna are likely to limit transmission, but from my understanding it's not as ironclad as the symptomatic cases data.

Re:US agencies call for pause in Johnson & Johnson vaccine on Tuesday April 13, 2021 @05:59PM (#26799890)
This is an excellent point, and exactly the reason why the UK decided to stop administering the AstraZeneca vaccine to people under 30. Not sure why you're being downvoted.

For people under 30, particularly women, the risk of blood clots from AZ is higher, while at the same time the risk from coronavirus infection is lower. When there are alternative vaccines available with no evidence of similar side effects, it makes sense to temporarily stop administering AZ/J&J to those groups to investigate if there are any risk factors we can use to predict and protect those who may be most vulnerable to side effects. (It has been suggested that young women on certain types of birth control are at highest risk of blood clots after AZ.)

That said, as some have pointed out, the risk of blood clots is still thought to be very low, even for women under 30, and anti-vax groups as well as the vaccine hesitant may see this news as a sign that it's not safe for anyone to take any vaccine. However, I don't think we as a society should actively try to conceal news or research about vaccine safety so that people don't worry. In my opinion, people have a right to know, and efforts to conceal concerning information often backfire, producing more public distrust.
