Kind of, yes. DeArrow is crowdsourced, and I love that people can submit a better title and pick a real frame from the video. I wanted one step more: the actual answer to the clickbait, right on the thumbnail, without waiting for someone to submit it, since it comes from the transcript. Only works for videos already in YouTLDR's cache for now.

I'm a big fan of SponsorBlock for YouTube too, from the same dev.

I actually love it. Thanks for finding it and sharing it here!

Even with a fresh dump, it would lag behind YouTube, since a video only gets in once someone links it on HN.

I took all the channels HN keeps recommending (3+ videos in Karpathy's data) and made a page with their fresh uploads as they come in: https://hn.youtldr.com

(I make YouTLDR, which writes the one-line answer under each video.)

Have been sitting on it for 8+ years. :)

My plan was to try to find the "answer" for videos in comments. Never really got around doing it, but LLMs make the possibilities more interesting and easier.

Edit: this is also a good opportunity to ship something like this: https://hn.youtldr.com, like Karpathy's HackerTube, but with the new videos from "HN-vetted" channels.

Same feeling. For me the trap was mostly titles and thumbnails, A/B tested to trap my time.

I made myself a thing that tries to answer the title + thumbnail from the transcript, and shows me the answer if there is a good one. Never launched it, but it's at youtldr.com if you want to try.

Re:100 Levels of Agentic Engineering on Monday October 26, 2026 @10:06AM (#50243961)
So, friends keep asking me for tips and tricks on working with coding agents. The answer is "it depends", and also, I have no idea what you already are or aren't doing. The gap in skills between the people I talk to is huge.

But your agent can see what you're doing! So I wrote down 100 levels and made it so your agent checks which ones you already do and suggest what to learn next. It reads check.md, runs a read-only script that prints only names and counts, and finds interesting things for you.

The 100 tips are based on my own usage, but also on what internet-famous engineers have been doing and sharing.

The code is at github.com/virpo/levels. Tell me what you think! :)

he has a nice take on review too: maybe it now means "something helps you maintain awareness of what you're building".

Re:How 94 internet-famous engineers use coding agents on Tuesday October 13, 2026 @08:47AM (#50070836)
Hey HN, I'm Peter. We are building a code review tool and I wanted to know how the well-known engineers actually work with coding agents now (and how they review code) and not necessarily just what they say.

So I went through their repos, blogs, talks, tweets of 94 of them and made a card for each of them. Things like agents, models, harness, rules, skills, hooks and how they review whta their agent wrote. Agents did a lot of the digging, so every claim links to its source and you can check it yourself.

Most surprising finds are, that 8 of 94 still read every line of their code, and 21 more of them read the riskiest parts and skim the rest.

You can also make your own card (with your own agent), and it will suggest what trick from these 94 engineers you should try adapting.

If something is missing on a card, it means I didn't find it, not that they don't use it. If you spot something wrong, you can open a PR, happy to fix it.

Your instinct is right - pine is just too soft for this, and I would expect the holes to splinter.

I used oak plywood, and it has held up well so far, including in our kitchen. You do get the occasional tiny splinter, but nothing serious.

The main trick for getting clean holes, especially on the back side, is to drill into a sacrificial board so the exit side stays supported.

What is really hard for me to wrap my head around is that this is just normal for our kids now. My childhood definitely looked a lot different.
Re: on Tuesday March 31, 2026 @06:06AM (#47585057)
Ha, I didn't even know BRIO had a construction set. We have the BRIO train and lots of LEGO here, but that somehow never crossed my radar. Now I kind of have to get one :)

For a bigger pegboard, I'd almost certainly go the plywood route, ideally with access to a CNC drill or a laser cutter through some community workshop. The hole precision mattered more than I expected, and getting a whole board right with a handheld drill was surprisingly tedious.

Re: on Tuesday March 31, 2026 @05:54AM (#47584951)
I bought a Bambu A1 Mini to replace an Ender 3, thinking it would just be for occasional printing. I wanted something smaller and better looking. The opposite happened: the process got so much easier that I now regret not getting something bigger, maybe even with AMS.

So while I can't compare the whole market, I can definitely say the jump in ease of use was huge.

Prusa printers are great too, especially if you care about supporting a company that invested heavily in open source. I found them harder to justify on price, but I also understand why people choose them for that reason.

There have also been pretty public disputes around Bambu's use of open-source work from the Prusa/Slic3r ecosystem, so that is part of the decision too.
