sebnun··on Ask HN: How many of you are self employed?
Thanks! fixed.
sebnun··on Ask HN: How many of you are self employed?
About 6 months ago I left my job to start my own company and make a language learning tool I always wanted to build (https://www.langturbo.com), It's something I use myself and I see real value in it.

I'm fully bootstrapped and I have some months left of savings to try this out. If this doesn't get traction then I guess I'll have to get a "real" job again :).

sebnun··on Ask HN: How easy is it to become an entrepreneur in 2024?
I'm going to write about my own experience starting a B2C SaaS.

I think it is much easier to build something complex in a short amount of time now than before. For example, you can use something like modal.com and have a very powerfull AI backend very fast, and you only pay when your services are active so you don't need to have deep pockets at the start. It was much harder (and expensive) just a couple of years ago.

On the other hand, this means there are much more people building things now than before, so it's much harder to stand out.

But the most important thing, I think, has always been your personal situation: do you have the luxury to dedicate your time to something that might not even work out in the end?

sebnun··on Launch HN: Univerbal (YC W23) – Language learning with a conversational AI tutor
Nice to see you here. I have been following your YouTube channel for a while, yes I think I discovered your channel via your videos about learning languages with ChatGPT (I'm building a language learning app as well so IIRC I was researching about it).
sebnun··on Anki – Powerful, intelligent flash cards
Nice, it would be useful to have this in other languages.
sebnun··on Show HN: Phrasing – learn every language, to any level
This looks really nice, I built something similar, mostly focused on podcasts now:

https://www.langturbo.com

I built something more complex before, that had YouTube content, AI shadowing tests, some built in SRS, but I chose to focus on the most important things first.

I actually started building my app due to the frustration of not finding any "intermediate level" apps. Good to see more options out there. Good luck.

sebnun··on Show HN: Anki/Duolingo-like app using educational YouTube videos
Neat. I built a web app to learn languages that used podcasts and YouTube transcriptions too. The problem with YouTube was that their API was very limiting, so I ended up having to use a proxy and some unofficial API to scrape the videos. The whole thing felt very sketchy so I ended up removing the whole YouTube functionality and just focused on podcasts (https://langturbo.com)

I hope you have better luck.

sebnun··on Show HN: Language learning app for intermediate speakers
Makes sense, I could add a player with a sample podcast per language before the signup form. Thanks for the feedback.
sebnun··on Tell HN: Merry Christmas
Same here. HN is the only site I keep visiting year after year. Merry Christmas.
sebnun··on Ask HN: What side projects landed you a job?
!Al menos cinco! All joking aside, great story @fipar.
sebnun··on Ask HN: Have you made IRL friends from HN usage?
No, but there's always a first time. If you are in Stockholm, hit me up at pablo at injavascript dot com
sebnun··on Show HN: SaaS Development Team as Monthly Subscription
If you use the illustrations from https://popsy.co/illustrations, you need paste an attribution link somewhere on your site.
sebnun··on Show HN: Developed from my Prison cell: A Libcurl TUI HTTP Client in Rust.
Very interesting read, I'm not fluent in Rust but it looks pretty good :)
sebnun··on Show HN: EdgeDB Cloud and 4.0 with FTS and Auth
How does EdgeDB Cloud compares to Convex?
sebnun··on Countries that Recognize Taiwan 2023
Being nit-picky, but France and French Guiana in South America should have the same color.
sebnun··on Show HN: Learn languages faster with YouTube and podcasts
Noted. Maybe a small definition popup should show first, with a button to the full page.
sebnun··on Show HN: Speech Meter – Improve Your English Pronunciation
Nice, I made something similar[1] but as a general language learning tool that works with 36 languages.

The main idea to improve your pronunciation is that you hear a native speaker (from a podcast or YouTube) and repeat right after, via Whisper ASR you get a score to see how accurate your response was compared to the native speaker. The method is based on the "language shadowing" technique.[2]

sebnun··on YouTube no longer suggests videos if your ‘watch history’ is turned off
On the Gmail app in iOS, when opening a web link I get the option to choose Chrome or Safari, I choose Safari and set the checkbox for "Don't ask me again" but the app keeps asking ... dark patterns are common in Google products.
sebnun··on Ask HN: Tell us about your project that's not done yet but you want feedback on
I'm working on https://openlang.ai (please try it on desktop, there are some bugs on mobile)

It's a web app to learn languages using podcasts, Youtube and chatgtp. I have been using these language learning techniques myself and I know they work better than duolingo or similar apps. I'm biased of course, but that's the reason I'm building this in the first place, I don't think there's any other app as effective out there.

It's not done yet, but it's usable on desktop. Any type of feedback is appreciated.

sebnun··on Cyberchud: Tech demo for the first TempleOS-first 3D game engine
Nice, the site also has TempleOS games. Very niche I would say.
sebnun··on Ask HN: Rapid Development API-Only One Person Stack – Seeking Performant Tech
I'm starting to use SST (https://sst.dev/) and really like it so far. The local development experience is great.

So I would say Node.js lambda functions in Amazon API Gateway via SST.

sebnun··on Show HN: LearnLingo – Converse with an AI-powered language tutor
Great work, I am currently building something similar.

https://www.openlang.ai (very rough MVP, please try it on desktop)

It has an AI tutor also like yours, but the main function is to learn via podcasts and YouTube using the language showing technique.

Based on my own experience learning a language, once you reach an intermediate level you usually hit a plateau, and you need to watch and listen to as much content as possible to improve.

The key is to keep your motivation high, and you do that by using content you actually care about. Learning a language shouldn't be something tedious but something you look forward to.

sebnun··on Whisper Jax: Transcribe a 1 hour of audio in under 15 seconds
I've been looking for faster implementations of Whisper, the main drawback with Whisper Jax is that the performance comes from running on Google TPUs, which are much more expensive than GPUs.

On "normal" GPUs the fastest implementation I've found is https://github.com/guillaumekln/faster-whisper. Whisper.cpp works faster on a CPU, especially on Apple Silicon, but still nowhere near the performance you could get on a GPU (understandably).

How does Whisper Jax compares to faster-whisper on a GPU?

Merry Christmas, let's hope for a better new year.
sebnun··on Supabase introduces MFA support
Great to see this. Unrelated but, is there any plan to add website hosting to Supabase?
sebnun··on Show HN: Make videos and images programmatically with CSS
Hi, I've been working on this side project for a while. I wanted to make videos programatically and I couldn't find a solution that allowed me the customisation that I wanted so I ended up building my own.

I started with the idea of using the Adobe after effects command line (aerender), then I looked into streaming the browser rendering into a video (mostly based on this video https://www.youtube.com/watch?v=5ioxcNHq8y0), and I ended up using remotion, a react library.

This is a (very) rough MVP. Any feedback is appreciated.

sebnun··on Werner Herzog eats his shoe
I would guess Annie Lööf. https://twitter.com/lindbergpolemik/status/14094562255955763...
