Hangout's encoding also it's a real performance hog because most devices don't support H.264 in hardware. Every time I'm in a hangout the fans come on and the battery rapidly drops towards zero.

Most devices DO support H.264 encoding. Hangouts however uses VP9 in Chrome and that's not HW accelerated. If you use Safari on Mac it'll switch to H264 and that will stress CPU less.

Yes, you are of course right. Confused the two.

That's been the present for the majority of most people's lives. Even with email there wasn't much, if any, time where the majority of people ran their own servers.

Email wasn't a proprietary protocol though. Xmpp wasn't a proprietary either and that 'present' wasn't that long ago.

That's why I mentioned running your own server.

No keyboard & mouse sharing. And to a lesser extent, not everyone wants a Google account. My employer also blocks some Google services. For example, I can't access Gmail. Trying to use Hangouts without Gmail is swimming upstream a bit.

Have you tried hangouts.google.com? It's possibly still blocked, depending on your employer, but if not, it's just a hangouts webUI that also allows calls.

Hangouts actually works at the moment, but work could change that at anytime, so making it a key piece of my workflow is unwise. I get your point though.

Gotta love life behind the firewall!

I'd love to see someone do the math how much CO2 is Google unnecessarily produce by enforcing VP9 because they are fussy about licensing fees.

I've tried to run 4K60 VP9 (and h.265 for that matter) video from youtube on the latest top spec MacBook Pro and it's completely impossible to watch. Transcoded to h.264 and computer barely gets warm.

I always wonder if people would be interested in a small SAAS providing a terminal demonstration and sharing service with web and terminal client. Users could on one hand share step-by-step demos for common tasks on the terminal (say "Let's build $foobar on Ubuntu 16.04 optimized for the following infrastructure") similar to asciinema.org and on the other hand share there terminal read-only to demonstrate live-debugging or development operations.

Obviously this is already possible using a setup involving tmux and ssh (or pixel-screen sharing via Slack), but maybe a streamlined service that has both a powerful terminal and web-client would be an interesting addition to some documentation-heavy workflows or remote debugging sessions. There is also shellshare.net, which is also a nice little project.

I worry that this could cause Slack to use a lot of memory.

LOL. I'm guessing you're sarcastically jabbing at Slack for the known issue that their desktop app uses a lot of memory.

I don't get why people use Slack app.

The whole Slack deal is to get away from desktop apps and run on the browser.

This opens up freedom to start Slacks where corp is blocking app installs (but not zealous enough to be blocking/MITM'ing network yet).

Still no linux support for video and now no linux support for screen sharing. Here's to hoping Google ramps up whatever Slack competitor they're trying to roll hangouts into.

Does Screen Hero work natively in browsers or require some sort of plugin?

I think plugins is a major buzz-kill for most people (like me).

For me, it's mainly because it gives me one icon that's always Slack, no matter how many browser tabs I have open, no matter how many windows or even different browsers I am using at once.

Click there, get Slack. No risk of accidentally closing it or losing it somewhere.

As someone else mentioned, they are finally doing some more with their purchase of Screen Hero most likely. However, one major feature that Screen Hero had that I don't _THINK_ this new screen sharing built in Slack has, is the ability for the other person to control the mouse/keyboard on your screen. I could be wrong, but if that is the case it's a huge feature missing. That was one of my favorite things that Screen…

I like Slack but I'm bit hesitant to have it the ability to control my mouse and keyboard all the time. Slack is so popular that there are certainly lot attacks against it and that could be one of the biggest exploits. I really hope operating system side sandboxing features mature and I'm able to control if and when software has access to such features.

In macOS at least, Slack and/or ScreenHero gets an entry under "Privacy > Accessibility" settings panel (just like apps like Synergy), where it begins disabled, and you have to explicitly go to that panel and enable it before it can do anything with your mouse/keyboard. You can disable it again at any time.
