There used to be a roundabout (unsupported) way to export from Authy Desktop to another app but Authy discontinued the Desktop app and Windows at least won't let you launch it anymore.
I'm not aware of a way to export from the Authy phone app.
And vice versa! The more you try to compress water, the closer you "push" it towards 3.98 centigrade. That's why water stays liquid below a certain depth, for example in the sea. Without that fact, water would freeze at higher pressures and no life would have developed in the ocean depths.
What does that mean for extreme environments like… a black hole? Water gets sucked in, experiences ultimate gravity and compression bringing it close to stopped time… at almost perfect 3.98?
Well, no, for more than one reason. First, for the water, time doesn't stop. Chances are it wouldn't even know it surpassed the event horizon (you know, if it could actually experience anything). For an external observer, it would crawl to a halt just outside the event horizon until it simply fades from vision.
Then gravitational tidal forces aren't strictly a uniform compression, on the contrary. Since gravity increases by 1/r^2, the part of the water drop that's closest to the black hole would experience largest force. That tears everything apart, so the water would be more dispersed instead of compressed. While I haven't done the math (and don't know if I even still could), I'd assume that gravity would quickly overcome Van Der Waals forces that holds the water molecules together, so it'd probably closer to water vapour than liquid.
And lastly, once it finally reaches the singularity, all bets are off. As far as I'm aware we have no idea what happens to matter in a singularity apart from contributing to its mass.
This is great, I've been looking for exactly that! Often times there are "hidden gems" of knowledge in longer videos, for example how some calculations for a specific problem are done when the rest of the video has a different topic. I found it very hard to look for these hidden gems.
How do I add a video? I'd love to test your solution with this video.
Thanks for making the source available too! I've been trying to build something similar with jupyter notebooks, but I keep getting stuck at this "hidden gem" problem.
Hey there! Thanks a lot :) I've gone ahead and indexed the video you shared and you can try searching something like: "how does heat sink thermal calculation work" as it tends to work better with question.
You could also add more videos by clicking on the hamburger menu on the right of the search bar and click on "Index videos". However, you'll need to do a quick email sign up and you can index as many videos as you like!
Yeah the "hidden gem" problem is a difficult one to solve and I think with the current tech out there, we are getting a step closer with better solutions. The search engine still has a lot of work to be done especially for broader queries & improving accuracy.
Would love to see how the community can build on this!
Thank you for answering and indexing the video so quickly.
I'm blown away how good this works! I searched for the query just like you said and it really found exactly the relevant section of the video. Very impressive!
You're right, the query seems to be very sensitive to the exact phrasing. Searching for "heat sink thermal calculation" results in nine videos, (the wanted one on fifth place at least), while your query seems more targeted. "calculate heat sink power dissipation" works reasonably well too.
So again - wow. This is really great and exactly what I've been trying to build for myself too.
One really useful feature for me would be inclusion/exclusion of channels in the search results. For this example, when I'm specifically looking for calculations, I can probably skip channels like LTT from the search results.
It doesn't sound ideal that it's so phrasing dependant - 5th on a list of 9 videos is poor if you're searching without knowing which video you're looking for and without knowing the best search phrase to use - unless those 4 above it actually also answer the same thing?
Is it random luck which phrases work best, or is it in a way that a frequent user of the service could learn the good and bad ways to structure a query (and/or can it be tweaked so that all queries work well)?
(Questions aimed at the world generally, not specifically at the person I'm replying to.)
Technically the other videos do talk about the above query, just that not enough videos of it have been indexed to produce a better result.
While yes promoting/querying tends work better in questions based on how its built, I've been exploring more ways by mixing full text fuzzy search along with the current method to allow for broader queries as well :)
I think I've found a (minor) bug, there seems to be an inaccuracy with the time stamps. I assume you're taking the chapter start and end times from the video themselves, but they don't align with the summary in this video:
For example, chapter 5, Heat Sink and Power Dissipation starts at 5:18 in your summary, but in the actual video it starts at 12:15.
EDIT:
I'm just now seeing that your summary only has 7 chapters, but the YouTube video is segmented into 13 chapters, so it appears you're not using them from the video after all. Are you doing the segmenting with the LLM as well? How do you get timestamps from that?
EDIT END
Anyway, thanks for this fantastic product, I was about to build something similar, but with a different focus:
Assume I've already seen a video and I want to look up a detail from that video, say how to do thermal calculations like in the example video, but I remember neither the video name nor the time stamp. I'm trying to build an app that generates embeddings for chunks / chapters of videos which I can then search semantically.
Do you have something similar planned? Because that's something I'd pay good money for.
Also, would you mind sharing a little bit about the tech stack? I'm assuming you're using yt-dlp to download videos with chapters and running whisper for a transcript, then something like gpt-3.5-turbo for summaries? Because that's how I'm doing it right now :D
I've had the same happen. I've registered and logged in via VPN with a UK exit node. Worked perfectly.
Even stranger, now that my account is created, the VPN seems to be no longer necessary. I can just login with e-mail and the token they send me each time.
I've just tried it, and for me it displays the entire litany (afaict):
Certainly, the Litany Against Fear is a well-known mantra in Frank Herbert's Dune series. It goes as follows:
"I must not fear.
Fear
is the mind-killer.
Fear
is the little-death that brings
total obliteration.
I will
face my fear.
I will permit
it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the fear has gone there will be nothing. Only I will remain."
But you can see the formatting is a little off. In fact, each time there was a double new line, the output paused for several seconds, before continueing. So what someone in a sibling comment mentioned about a content filter seems plausible to me.
