Socket.IO C++

“Socket.IO also gives you things like cross-everything callbacks: // server io.emit('event', function (msg) { console.log('Client responded!', msg) }) // client io.on('event', function (cb) { cb('This is my response') }) And it also provides socket namespacing, and "rooms" (a bit…”

Socket.IO P2P

“SockJS is definitely a reasonable choice as a base. At Pusher we use a fork of SockJS for HTTP fallback but we actually use em-websocket [1] (ruby) for our WebSocket API. Given the opportunity we'd probably move away from SockJS to something much simpler because we only want the…”

Welcoming Rocket.Chat to Matrix

“Even if Rocket.Chat used the same E2EE scheme as Matrix, you would still have to re-encrypt, given the application-layer protocols are not the same. RC's messages are a blob of JSON which looks nothing like Matrix's JSON events. To preserve E2EE throughout you'd have to speak…”

Welcoming Rocket.Chat to Matrix

“True, although this is one step away from being a multihead messenger, effectively. It's just that the protocol-specific modules are daemons using a standard API rather than in-process. For instance, I can't think of a way that one would run an Element Web<->Rocket.Chat bridge…”

Launch HN: Chatwoot (YC W21) – Open-Source Alternative to Intercom, Zendesk

“Alex from Papercups here :) My guess is partially what vardaro mentioned (to hedge their bets), and partially because the space is really, really "wide" (not sure if that's the right word) in the sense that products like this could go in a million different directions... for…”

Launch HN: Chatwoot (YC W21) – Open-Source Alternative to Intercom, Zendesk

“Oh, wow. I used Chatwoot in the past, happily surprised you went through YC! I did have trouble self-hosting once, I think I had to enable task queues in my Heroku or something. I might've eventually switched over to the hosted option which was much easier. I would use Chatwoot…”

Jitsi Meet: An open source alternative to Zoom

“You could use LDAP, but really the default configuration allows for Prosody commands, e.g. prosodyctl adduser [email protected] What I did was set up a vanilla Jitsi Meet instance (on DigitalOcean) and then create a shared user / pass per room share with my team. Feel free to…”

Proof of concept: end-to-end encryption in Jitsi Meet

“Jitsi Meet even shows a popup saying Firefox is not supported, and the only fully supported browsers are Chrome and Chromium. You're right that screen sharing does seem to work in Firefox! Thanks for pointing that out. It looks like FF on my Linux box is blocking it, but I guess…”

Dropbox has open-sourced Zulip

“Thanks for using and contributing to GitLab! Although Zulip is far ahead of other open source solutions we are leaning towards Rocket Chat. Javascript and Meteor are the most popular language and framework so it would be easier to contribute. It is not who is ahead now but about…”

Dropbox has open-sourced Zulip

“Zulip can be hosted internally, and there is a desktop Linux client in addition to running fine in the usual zoo of Linux web browsers.”

LiveKit – Open source, high performance WebRTC infrastructure

“I am so impressed how quickly LiveKit has developed and become polished. If you missed it they wrote a really good article on it here[0] I also really love as a company how LiveKit operates. I work on an Open Source library they use (Pion). They contributed so much upstream and…”

LiveKit – Open source, high performance WebRTC infrastructure

“You certainly could, there are some folks in the community building Twitch-like livestreaming experiences with LiveKit. One of my teammates built a mobile livestreaming demo app, perhaps I can convince him to release the code. ;) Update: Given that this is for internal use at…”

The most surprising thing I've seen in 2009, courtesy of Etherpad

“Cheating is a difficult and important problem, but I'm not sure this solution would be worth the inconvenience it would cause. If it only inconvenienced cheaters that would be fine -- but I think it would also cause some honest students and teachers a lot of trouble. First,…”

The most surprising thing I've seen in 2009, courtesy of Etherpad

“"I doubt everyone will abandon their word processing software and user Etherpad." They will probably give up Word for something, eventually. Especially among the current generation, writing is something done online; a blog, an email, a tweet, writing on someone's wall. At some…”

GitHub open sources Hubot (chat bot)

“Hubot supports IRC too (though probably not as well, we only hop in when Campfire goes down). We depend on having a nice, customizable native Campfire client. We keep a custom js script in DropBox that Propane ( ) loads on startup. We've been able to modify the UI to show…”

GitHub open sources Hubot (chat bot)

“We're just shipping the foundation right now. A lot of our other stuff is tied to a substantial amount of other services (our CI, our special build layer, various other home-grown services, etc). Over time — and judging from Twitter, very quickly! —…”

Force only TLS and DTLS sockets not working

“As commented in [this group post]( `--no_tcp` and `--no_udp` flags do not disable plain sockets. Intead of that, activating both only disable `listening-port` and continue enabling `tls-listening-port`, but accepting both, plain and TLS/DTLS connections. I would like having…”

PeerJS – Simple peer-to-peer with WebRTC

PeerJS – Simple peer-to-peer with WebRTC

In 1973, I invented Baileys

“> We needed what they called an “Anglo-Irish” name. We were sure that a family name might be better than a “thing” or a place name. That was the popular convention of the business in those days. After all, many drinks were named after the people who made them. > We were still…”

In 1973, I invented Baileys

“If you mix it with, e.g., toffee Frijj[1], then you can't taste the Baileys at all. But you will wake up 36 hours later wondering what happened to your weekend and the rest of the Baileys. [1] Thick milkshake kind of stuff in the UK”

Vulnerability in the Mac Zoom client allows malicious websites to enable camera

“Your proposal is the closest thing to the best solution I have seen. It still has at least several issues: * When Zoom is already installed: - should be able to handle most instances - needs to account for version management, eg installed version zoom could still be version that…”

Vulnerability in the Mac Zoom client allows malicious websites to enable camera

“Those are some interesting points. I'm not convinced that versions should be in scope for this sort of thing though. If I'm writing a protocol handler, I think it's my responsibility to make sure my software can update itself, and make the default behavior that it should check…”

Monitoring Raspberry Pi Devices Using Telegraf, InfluxDB and Grafana

“InfluxData doesn't make money from Telegraf at all. It fills a need (data collection) that InfluxDB users have, so it helps them which helps us, but it also helps our competitors whose users also use Telegraf to collect data. The reason merges have been a problem is that…”
