It might be neat to integrate DeArrow to fetch thumbnails instead of just arbitrarily picking picking a 50% screenshot. It could also be used to replace the titles on the server side.

Sounds good, but could you please make it so that it can also be viewed without Javascript being enabled?

I currently use downloaded and curated youtube videos on my local server ( mostly for my kid so that I don't have to deal with youtube autoplay or her clicking something kid would ), but this is just a reminder of much google has changed for the worse.

It would be nice to have some context for each video, a summary of the comments that recommended it in the thumbnail tooltip?

bch • today at 9:51 PM

Would love to see the list of submissions and comments that positively contributed to this.

How do the categories work? I'd download the video transcripts and embed the text (maybe summarized first). This way you could support custom categories via embedding similarity.

Now redo it with DeepSeek 4.1 Flash, see how it compares.

Some of the Alan Kay lectures are on hackertube

It would be great to have an option to sort videos by upload date, so it's easier to discover recent content.

Interesting idea! Also funny that the fourth recommendation for me was a video with Andrej himself :D

Seeing Prejudice by Tim Minchin on the front page makes me very, very happy.

Love Tim Minchin <3

What is a 50% thumbnail?

I went into the blog, and saw only two entries in 2026. I dont know how to feel.

I dont know if its because the new state of things is that all knowledge is now secret and cant be shared.

Or if its because Opus 5.5 has turned even Karpathy into a product owner/manager so now the only interesting things are products (hackertube in this case).

Either of them makes me sad. Although its probably both.

Wake me up when true science is back.

In any case, im a big fan of Karpathy.

Could this not just be a playlist?

I'm actually surprised this was that easy to do, ngl

> I'm sure this algorithm works well for the median person on the internet, but it definitely does not work for me

I see this sentiment expressed a lot regarding a variety of ways the internet has been enshittified. Are we really sure the median person would prefer this to better content if they were presented with an alternative?

And even if they would - what are the ethics of knowingly feeding slop to the masses?

i wished yt would be so fast. yt itself is the most bloated heavy app

I found this gem there: Rails Conf 2012 Keynote: Simplicity Matters by Rich Hickey (https://hackertube.org/watch/rI8tNMsozo0)

And lol ... Can you imagine how savage this is, with Rich's disgust with ORM and entangled concepts and like the audience sits there with their ActiveRecord and 10 levels deep inheritance and rails 'easy way' of doing stuff. Probably was a bigger shocker than dHH's keynote this year. lol

mbed92 • today at 8:49 PM

Really cool idea. I also realized recently that whenever I enter YT, I enter "nshittified wall of slop"...

mentalgear • today at 8:29 PM

Appreciate the effort, yet I think there is a place this is needed even more:

> It was Friday night at 11pm, I was tired, I went to YouTube to watch something and realized that I was looking at an enshittified wall of slop.

Please do the same thing on Social Media: Facebook, 'X', reddit, instagram, etc . Maybe find a 'hacker signal' that identifies quality content across those platforms and have them aggregated for the public so we don't have to spend time in the fascist network prisons.

The greatest trick - if it even can be pulled - would be setting it up in a way that it can't be sued out of existence by the angry platform overlords - if you can do this, then you are truly a genius, sir.

Free the people.

> Media, journalism & propaganda

Amen, we should label it correctly more often. Hard to miss it nowadays, I guess.

Where is the source, so I can roll my own specialized video site?

Changelog push from HN comments on this thread:

- Filters on search and topic pages: upload date, duration, type (talk, lecture, documentary, ...), and sort by upload date, view count, etc. (ty jahala, kiuiras, mixtureoftakes)

- Filters are now on the home page too, no need to search first. Picking one shows all matching videos, e.g. every lecture over an hour. (ty kkotak, macote, Aboutplants)

- Sort by "Recently recommended": orders by the latest HN recommendation instead of upload date, so a 2012 talk that someone linked last month floats to the top. Also a chip on the home page. (ty beaconflint, mixtureoftakes)

- Sort by like ratio as a quality signal: likes/views, damped so small videos can't win on a handful of likes. (ty gpugreg)

- "Play all on YouTube": turns the videos on a page (up to 50) into a temporary YouTube playlist, so it works in the YouTube app on phones and TVs. A start toward real HackerTube playlists. (ty twalichiewicz, waschl, victor9000)

- Removed the YouTube-looking logo. (ty doginasuit)

- HackerTube Longs: every video over an hour, right where YouTube puts Shorts. (ty gosen)

- Bonus: "Hidden gems" filter (loved on HN, under 100k views on YouTube), and "Evergreen only" to hide news-of-the-week videos.

I can't find it on GitHub. Is it open source?
