Re:Ask HN: What Are You Working On? (December 2025) on Sunday December 14, 2025 @10:47PM (#46270225)
Working on Bold (https://boldvideo.com)

Video intelligence platform for coaching programs and training companies. The problem: these businesses sit on 200-500+ hours of video content that becomes a "content graveyard" - students can't find what they need, coaches burn out answering the same questions, churn stays high.

We do deep transcript + metadata extraction, then layer RAG search and an AI assistant that can answer questions with timestamped citations back to the exact video moment. Think "ChatGPT for your video library" but with accurate sources instead of hallucinations. Tech: Phoenix/Elixir backend, Next.js portals, two-tier RAG architecture.

Currently serving a few coaching programs in high-touch sales mode. Would love feedback from anyone who's built RAG systems over media content - curious how others handle the signal extraction problem (transcripts are noisy, you need to identify what's actually being taught vs filler).

I love this, looks really well done. I don't have a windows computer or steam deck but just got a copy anyway because I like the whole story and vibe around it. Also great that you offer the source as DLC as well, I will def check it out! I wish you both the best of success with this! :)

This looks neat.. I can definitely relate to gathering feedback on documentation is either a mess or non-existent. Good stuff!
Looks very cool! Besides the search, which works great and feels like a powerful tool, I like how snappy the word highlighting is in the transcripts. Can you elaborate a bit on how that's done? Thank you, this is really great work!

Thank you, this is really interesting! :)

Wow, this looks incredible! Love how the underline travels and guides the eye.. Very impressive!

Excuse the question, but "forced alignment" is when you don't have timestamps, like in webvtt?

Re:Whisper – open source speech recognition by OpenAI on Thursday September 29, 2022 @09:36AM (#33020422)
As interesting as it is funny. Great benchmark! Here's the rev.ai output for comparison:

  Speaker 0    00:00:12    Oh, fuck motherfucker. Okay. Fuck, fuck, fuck, fuck, fuck, fuck, fuck, fuck. 
 My little fuck.  
  Speaker 1    00:02:10    Oh, fuck. Oh, fuck,  
  Speaker 0    00:02:25    Fuck, fuck, fuck, fuck, fuck, fuck, fuck, fuck my motherfucker.  
  Speaker 1    00:02:53    Fucking a.  
  Speaker 0    00:02:54    Mm-hmm. <affirmative> motherfucker. Fuck me. Um,
fun headline if it's not even clear if the driver was driving or not.

> Whether the vehicle was driven by the 43-year-old driver or not is the subject of the investigation and is currently unknown, a police spokesperson said on Tuesday. The cause of the accident remains unclear.

Same here. 2014 maxed out, doesn't do well in the spanish summer. External screen mostly stays disconnected, otherwise it throttles down after 30 mins.. Are there not some kind of cooling pads to help with this shit?
OK, I guess when doing OP's root trick, the root user gets activated/created, and that's that's when the PW gets set to empty. I guess that's where my passwordLastSetTime comes from.
My root pw passwordLastSetTime says this morning.. the fuck??

Discord is pretty snappy, even with tons of users..
I agree. The stall Bourdain went to, across the street at Maxwell's, has always super long queues. Not 90 mins but still a pain. I'm glad most of the other stalls are usually not far off on their quality..
Most of the food stalls in Singapore and elsewhere are closed one day per week.
Re:Show HN: Learn English with movies and TV Shows on Tuesday May 28, 2013 @12:52PM (#5781085)
I did, and still do the same thing. I can't even recall how many times I watched friends, entourage or deadwood. (I'm a Kraut, too, by the way). It helps massively, especially with slang. I want to do the same thing now for spanish.

Edit: Oh, and I still watch everything with captions, in case I missed something or there are words I didn't know.

Geez, that looks tight! Can you tell us something about the stack?

Ha, something like that wouldn't surprise me these days. Of course I signed up for the mailing list, looking forward to more exciting 'product announcements'.

Damn, this is nice! Thanks Heroku! I love the service, but 200 bucks as the lowest price point for a dedicated db didn't always make sense to me, especially in the startup world. This changes everything.

Re:My experience with a 'negative review' scammer. on Wednesday August 03, 2011 @04:26AM (#2840278)
Interesting story. Well, this Brian guy is an idiot ("You unfollowed me. I insulted your tea. Now go away!"). Really?? But what I like most is the last comment on teatra: "Reviewers who judge about a tea quality from the point of someones followunfollow in twitter is… well such people earn 5bucks a week. Period." Nuff said :)

By the way, I need to try that stuff. Cheers from Hong Kong.
