I'm pretty excited about this. I'm admit I was skeptical when I saw a similar LiveView based notebook a couple months ago, and wondered why not just make a kernel for Jupyter. But with the idea of real-time collaboration I get it. And with the momentum of Jose and team behind it, I think there's real promise here, especially once they figure out widgets and charts, which they have an open issue for. I program in Elix…

There are already Jupyter kernels, IElixir and ierl (which I wrote). The latter supports Erlang, Elixir and LFE right now and supports connecting to another node as well.

Try not to sound like you're diminishing the efforts and accomplishments of others. This is tremendous work, they're running their business and come up with generic/generalisable solutions instead of narrowing the outcome to their own benefits only.

When Facebook spends engineering effort to work on React, it's not out of the kindness of their heart, and that's ok. It's still productive and an accomplishment, it's just productive for a reason that pertains to their business. It is the same here. This tool helps the adoption of Elixir, running Elixir is their business, so yay! But the comment I was replying to implied this is somehow entirely separate from their…

FB has thousands of engineers. It's not that often that a small group of people can both keep the lights running financially and also develop fully featured massive libraries. I'd say that counts as a very productive company.

To put context on that - it's still TLS, the cookie is just a password. The problem is that it's one password for the node network, and you either have it, or you don't. So there's no real administrative control over access; it's shared password.

And a browser can be tricked into sending the cookie if you accidentally misconfigure the server. You will have no indication or warning of this happening, from either the client or server side, if you get it wrong.

If u use live book to print the erlangs distribution cookie, u still would need to steal the inter nodes certificate and be on the server network to do any shenanigans

But how would u get into livenotebook in first place if u shouldn't have access to the container it and the connected nodes run on? I mean u can easily destroy a production system with couple erlang commands

It recently hit top 50 on one of the big lists of programming languages and I see more people getting into it every day. It is growing unless there's s lsrge drain hole somewhere. Might not be growing relative to other larger langs but I'm fairly certain it is growing. And I've heard a lot of concern about it being niche so I tend to mention that it is growing. Because in my experience the biche is quite large and ..…

There's quite a disconnect between the amount of attention it gets on HN and the fact it's not in the top 40 languages. I mean Tiobe index has it behind Lua, Lisp and RPG (?). So yes you can definitely say it's a niche.

This is a forum composed mostly of software engineers working on web technologies in young companies or startups, which means we're usually at the bleeding edge of computing.

The TIOBE Index represents the world of computing at large, including embedded development, industrial, financial, automotive, medical, hardware, etc. This is why C and Java are at the top of the TIOBE index and I'll argue will be there for the next 40 years, and doesn't mean that any language which is not C or Java are unpopular or niche. Ours might be a small percentage of total computing, but would you argue that web technologies/the Internet as a whole is a niche?

There is a reason the embedded world still uses C, and there is a reason the web world doesn't. Using the TIOBE index as popularity contest is misguided.

Be careful, websockets are tricky to secure and get right. It's easy to do something like forget to check the origin and now you've opened up a whole class of cross-site websocket scripting attacks. I love the idea of easy access and nice UI to prod machines, but put it behind a secure proxy or VPN layer and not facing the public internet.

Hmmm. Nginx has an auth_subrequest module that yeets all the cookies in a requests over to a configured URL in a server-initiated subrequest (hence the name), then proceeds with the original request only if the subrequest returns 200 OK. The module works with any type of incoming request, including FastCGI and reverse proxy situations. The idea is that some config magic turns the 401 into a 302 redirect that walks yo…

To add, something similar can be done with Traefik and forward auth plugins.

Elixir is niche. It's number 48 in Tiobe, in Redmonk it's not in the top 20, in Stackoverflow yearly surveys it dropped out of the list (too little usage). You mean to tell me a programming language not in the top 40 isn't niche? Hey I'm a Rubyist and I acknowledge the fact Ruby is niche (in some cities/countries you will have difficulty getting a Ruby job), yet even Ruby is way more popular than Elixir.

Years.

Interesting that I'm getting down voted, I'm long on Elixir and betting my startup on it.

I didn't down vote you, but my guess is that it was because you commented a single word. Also, because of the position of your comment, I had to scroll back up in order to find the context.

I can’t reply directly to the comment below yours, so it will be as a side comment.

I don’t think anyone is arguing Elixir isn’t niche, we are just explaining why Elixir gets attention on HN even though it is top 50 on TIOBE. HN itself is focused on certain domains and tends to be early adopters.

I think a lot of Elixir devs think or want to believe Elixir is bigger than it really is. That's what I understand from the guy I made the comment to. Now I don't enjoy popping people's bubbles but I think it's better for everyone to acknowledge the truth and then think how to deal with it.
