cool site. I've been wondering about building a video streaming app/platform but unfortunately I couldn't find anything related to that here. Any pointers on how one can go about building a Zoom like service? Is Web RTC the way to go?

KingFelix• 6 years ago

Have you checked out Jitsi?

jakelazaroff2• 6 years ago

WebRTC is a good start! I played around with it at the start of the pandemic. It's pretty quick to get to a working demo, and you don't have to worry about any of the gory details with regard to video.

rizpanjwani3• 6 years ago

I played with WebRTC as part of a masters project about 7 years ago. I wonder how far it has come. It'd be nice to have some sort of a plug and play cloud service to deal with multimedia streaming in realtime and you can focus mostly on logic and UI/UX

aquadzn7• 6 years ago

I just added four video chat / call projects :)

rizpanjwani3• 6 years ago

Thanks! I'll check it out later!

aquadzn7• 6 years ago

Lol, didn't expected to be on HN. Thanks @didizaja

didizaja• 6 years ago

You're welcome! I saw it and immediately thought it was something that a lot of people might find both interesting and useful. There are so many projects on the site that I want to try out, and I love the fact that it can grow organically as people choose to contribute new projects to it.

Amazing work on the awesome idea and on the execution! :)

the_arun• 6 years ago

Also liked the way you are hosting it on github pages. Smart move.

sundarurfriend• 6 years ago

Could you show an error message on the site in case Javascript (or just 3rd party JS) is disabled? Without JS the page gives no indication anything is missing, it just looks like a beautiful page with only an "Add a project" button: https://i.imgur.com/SReAOYG.png

aquadzn7• 6 years ago

thanks, yes will do

Tau5• 6 years ago

Very cool!

Grimm13• 6 years ago

I really like the concept, I look forward to seeing more diverse projects added to the index. I looked for, embedded stuff, virtual reality and high frequency trading and got 0 hits on all of em :(

mhh__2• 6 years ago

high frequency trading

Take a pile of money, burn it.

Obviously I'm joking, but I would assume that the local nature of HFT basically means you have to be a big-gun to play without losing your money.

Grimm13• 6 years ago

I'm not super concerned about losing money on a hobby project :P hard limit 1grand let it ride.

RhodoYolo• 6 years ago

Couldn't find any Arduino projects but i wanted to contribute. After a quick google search, I found this:

https://create.arduino.cc/projecthub

Which seems to be a narrower mindset of the OP's vision. Should i link that page or pick a couple projects?

aquadzn7• 6 years ago

I didn't know about this site, it's nice. If I can, I'll try to scrape it and add some Arduino projects.

aquadzn7• 6 years ago

just added the first 10 tutorials pages from this website

mhh__2• 6 years ago

I'm really tempted to document my own learning/musings in microarchitecture by making a semi-zachlike "game" to go through it. Really stretching the definition of game though, although I know I'd play it which is enough for me.

There's already one on steam, but I don't think it uses a real HDL - thanks to yosys (Claire Wolf you're a god) it could be completely open-source, and you could even just about gamify the end result (Dhrystone MIPS per gate?)

mjfl• 6 years ago

I looked at the title and thought "You know it would be really cool to learn rust by making a Roguelike with it". Then I clicked the link and searched for Rust and there it was! Upvoted!

semireg• 6 years ago

Maybe this is an opportunity to create a new kind of Show/Ask HN, called “Who’s got questions?”

For example. I’m a self-described senior electron/react/iOS app dev and I have created exactly one API in my life using node/express/GraphQL/mongo/redis on heroku. It works great! I had a ton of fun learning and deploying and now maintaining.

Now... I want to add some features such as long-running (30s-10m) batch jobs. How do I go about doing this? I noticed Redis has Bull ... but I’m still not clear on the architecture. I feel a bit stuck and nervous I’m going to pick something that’s going to fall over at the slightest traffic.

ranit• 6 years ago

Nice idea. Hopefully gain a traction.

tapland• 6 years ago

One thing I do enjoy on reddit is the communities that run 'weekly stupid questions´-threads.

onelovetwo• 6 years ago

Does anyone know of a similar website that aggregates youtube courses or any free course for that matter?

jokethrowaway• 6 years ago

If you're talking about having periodic jobs to run you can use heroku's scheduler plugin and start a job. It will use a different dyno from the one running your api.

You will end up paying more, but you won't have problems with resources sharing.

In a traditional VPS environment you would have needed to have a machine beefy enough to run both api and jobs or spin up a new machine. Cron, Jenkins or another task runner could have achieved the same.

If you're talking about having long running requests initiated by users, a common pattern is to have a queue:

- User send a request

- API add request to a queue

- n workers wait for a queue message and process it once it arrives

Another simpler approach is to just spin another instance of the API and just forward long running requests to the new instance. Depending on the type of job, its dependencies, its frequency you may run into some problems that you wouldn't have with the queue based approach

computerex• 6 years ago

Use a queue. For example, a redis list. Then you can have scalable workers lpop to process the jobs and save the results somewhere. Would require 2 endpoints, one to schedule the job and one to fetch the results. You can generate a uuid to id each job.

Or you can use a managed queue service like SQS as well.

I detected videos of Siraj Raval to learn deep learning. That make me doubt of the teaching quality of the site.

amitport• 6 years ago

Can you elaborate? (I have no idea who he is)

mikewarot• 6 years ago

He plagiarized a lot of stuff, and eventually confessed about a year ago. It was a lot of flash/pizazz, with not as much substance as you really needed to learn something.

I haven't checked in on him since... maybe he's doing better at teaching now?

love this already, been trying to learn webrtc

hoten2• 6 years ago

Any suggestions for hardware? I'm currently going through Ben Eaters videos on youtube, going to get his kit soon. Seem like it's a great resource. Any more?

tsjq• 6 years ago

Raspberry Pi ?

_xoo• 6 years ago

Check out https://nandgame.com/ if you want to apply some of your knowledge from the videos on youtube.

hoten2• 6 years ago

This looks super accessible and low-investment. Thanks!

dasfsi• 6 years ago

Search is good, but if you're like me and would like to just see the list of available projects, it's here

0800LUCAS• 6 years ago

Nice project!

Would be great to have a way to search by technology.

aquadzn7• 6 years ago

thanks, I wanted to add it but I don't know if a long drop-down menu is ergonomic on mobile.

fardeem• 6 years ago

This looks really cool. The thing that makes me sad is that there are way too many resources on stuff like React and python and not much material on stuff like webgl. I wanna learn webgl!! Where do i go

cheese65536• 6 years ago

Here is a Udacity course using webgl: https://www.udacity.com/course/interactive-3d-graphics--cs29...

Here is the Class Central page with reviews: https://www.classcentral.com/course/udacity-interactive-3d-g... You can search for other courses on class central, though searching for webgl didn't actually find the Udacity course - had to look at related courses for a no longer available Coursera course listing that searching did find.

Edit: Also, Packt's free ebook of the day is currently Learn Three.js, which is a wrapper around webgl. Only available for the next 9 hours or so. If you don't have a packt subscription, you can only read it in a web browser. https://www.packtpub.com/free-learning

nudpiedo• 6 years ago

The idea is very interesting although at the moment it seems to cover only popular choices. I tried to look for prolog and I found no results at all. Same for other topics like knowledge database or petri networks for which google is just a better option.

I hope they can somehow automate the data input for the search engine.

Luuseens• 6 years ago

My pet peeve: there are still many developer-oriented sites (including this site) that can't handle special characters in search. For example, searching for `C#` or `C++` returns C, C++, C# results.

aquadzn7• 6 years ago

I just added a parameter taking into account # and + for C# and C++. The results goes from 140 without to 27 and 111 with.

joshxyz• 6 years ago

Oh dear this is a pet peeve when I was searching for pirated video tutorials back then.

bordercases• 6 years ago

I notice that the search is not doing partial matches within words, e.g. "RTC" does not bring up results with "WebRTC" in the title. Not sure how this would affect other results.

It looks like the list "Build your own X" https://github.com/danistefanovic/build-your-own-x
