I don't think Qt has ever pretended to look native. I remember using KDE back in the early 2000s and most Qt apps that didn't explicitly integrate with KDE didn't look "native" either. The other desktop OSes are not even internally consistent -- look at Windows's "settings" vs. "control panel". Which one is native? The answer is they both are, sort of, but there are simply two UI kits bundled with the OS. One is depr…

For me this was never about the look, but about the features. Zoom chat isn't even able to do scrolling properly !!

huh, what do you mean by that ?

You can force it to use a web app by declining permission to run locally. The web-app has fewer capabilities (no gallery view, last I used it), but works great. Also, Meet is fully-featured and runs entirely in-browser.

Meet performs quite poorly with large number of participants (the tipping point being around 10 or so for me) in a meeting. I tried various browsers and found Chrome to be the worst performer and surprisely Firefox was somewhat better but still needed a refresh every now and then. Macos on a 2017 MacBook. This is one of many reasons keeping my $employer on Zoom. We just haven't found a decent video conferencing softw…

Evidently, it depends on multiple factors.

My son's school uses Google Meet for online classes. 2 instructors + 36 students per section. All participants have their videos switched on. Even when the bandwidth fluctuates, we haven't noticed issues. In particular, Meet degrades well: audio continues to be high quality, with video becoming grainy or getting suspended. But, that is pretty rare. And, slide shows are never a problem.

Have you already tried to paste long(ish) text into Zoom chat ? It literally starts going (hidden) outside of the window ! I've been using software since Windows 3.11, and I don't remember that ever happening before !!

I sometimes paste semi-long code snippets and don't remember having anything weird happening

Zoom is entirely banned at the two companies that are my day job, and probably 90% of partners. If you do any work adjacent to anything that's ITAR controlled you should also not be surprised to see the same policy from partner companies. This has been in place for quite some time since the initial security problem that was so egregiously bad apple had to resort to using the malware removal tool to remove zoom's bina…

I don't like it but Zoom is soooo much better than Webex when I'm doing remote desktop support (those are the only options we're allowed). With webex the lag is awful amd makes it difficult to type, especially in a terminal, and the interface takes up so much space around the screen being shared for useless crap.

this was the case here too, but just yesterday got on a usaf hosted zoom that said 'gov' and hosted in CONUS so they seem to have some offering at least DoD is ok with now, appears to only be fedramp https://www.zoomgov.com/

County courts in my area use Zoom as well.

Ah that is interesting. I work for a school for Deaf learners who use sign language. We rely on having good quality video so we can see each other. Your description of video degradion matches my observation. Unfortunately this is not suitable for our use case. Zoom maintains high quality video really well on the same connections meets will degrade quite badly. I've always thought there should be a switch to decide which of video or audio should receive priority.

See Qubes. Your compromised app can’t do much without a Xen hypervisor zero-day.

> Your compromised app can’t do much without a Xen hypervisor zero-day. Of which there have been plenty.

Attack surface is much lower. Qubes is a massive improvement over a monolithic OS.

I have never used Teams but is 1GB of memory usage really an issue in 2021, when most laptops have at least 16-32 gigs of memory? It's been years since the last time I actually worried about how much memory some software on my laptop was using.

"2021, when most laptops have at least 16-32 gigs of memory" Oh man, I'd love to live in the wonderland where you posted this comment from.

I mean my laptop from 2014 had 32g (and like another 4g on the graphics processor) so that's not exactly outrageous for anyone doing serious work.

My laptop from 2019 also had 32g and was less than 2000 usd.

Obviously most people don't need that and I'm sympathetic to anyone having to run teams on some shitty IT-provided low cost laptop loaded with 7 different management spyware suites, but 16g-32g is not baller in a limo outrageous.
