My prompts are getting shorter and dumber because the model "gets" what I'm doing even with fewer words. It's almost to the point where if you give it too much, you're constraining the model with too many requirements, when the thing it would have done otherwise was better/smarter. So I feel like the prompting meta is moving more towards fewer bits administered just right. I go back and forth on whether I should make a video on it because on the one hand people have these questions but on the other my best practices look so dumb it's almost embarassing.

Only with Opus 5.5+. The thing is beast mode. I wouldn’t trust other weaker models this much.

No i don't recommend those anymore. Currently I recommend Epoch's ECI. AA was kind of bad but recent changes are trending a little bit better. I think benchmarks are in a really bad state right now otherwise, I basically don't trust them, good related reading https://epoch.ai/data/benchmark-reviews-documentation/includ...

Sometimes I say something like "check recent cyber stuff" and it dispatches a few subagents and does the thing.

I think many experiencing the same thing but we're way too small drop of a drop in the bucket that it doesn't even resolve in all of their measurements and A/B tests. The vast majority of the "gradient signal" is from normies and their patterns, desires and tastes are different. Basically I think we see a massive deterioration of quality because we are a rounding error.

I didn’t touch anything manually I only talked to Claude the whole project, except for YouTube API key, domain, its DNS record and VPS node boot.

There turns out to be an export on HuggingFace as well as a bunch of parquets.

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.

The average thumbnail on YouTube these days is some guy looking like HOLY SHIT, tearing his hair in amazement looking at something with an arrow pointing at some detail. "TOP 10 XYZ. YOU'LL NEVER BELIEVE #6". Like and subscribe. Utterly repulsive.

first do a search, then on top you'll see "Filter". might try to make more prominent from main page

correct. it means the thumbnail is sourced from exactly halfway in the video, so you get a representative frame.

I didn't publish the server because it's a vibe coded mess, but if you point your Opus 5.5 at the zip and ask for YouTube-like site it will be basically instant. This part was like 3 min.

EDIT: one caveat is that i couldn't distribute the YouTube data so you'd have to create a (free) API key for that part. Luckily it's only ~1 min of hassle.
