If you’re stuck in the frozen state, you can Ctrl+alt+delete 7+ times quickly to tell systemd to try to restart the system.

Less destructive way would be to try to open a terminal session with ctr+alt+f3 (or any f key) If it’s only the gui that’s frozen. Makes it also possible to troubleshoot things from there. I had this issue recently. AMD core boost caused random freezes to kwin.

Yeah there was some Radio Free Asia money connection with the open whisper system that now is Signal.

Of course I don’t have any concrete proof. If there was concrete proof we shouldn’t be having this conversion. My main issue is that it’s centralized and that’s a huge black box. People obsess with this “but it’s protocol open source” like headless chickens when that’s not the issue. Open source is like the step one when it comes to private and secure messaging. It just comes down to if you trust the devs and those doing the hosting. When it’s central all of that thrust rests on that one group and their hosting service not fucking you over even if they can or can not read the encrypted messages themselves. I’m not concerned signal keeping people’s dickpicks private here in that that even whatsapp is as good as any.

I see I made the mistake of coming to an obvious fangirl meeting to have an serious discussion about security merits.

Even if we assume that man in the middle attack is impossible with signal. Intelligence agencies care more about metadata anyway. Remember that getting meaning from terabytes of daily messages hasn’t really been viable way to mass spy anybody until very recently, since you needed humans to read them individually to get any wider sense of chat logs. if they know who talked to who and when. With those they can social graphs and get a list of suspects when everybody is tied to an identifiable phone number. Yeah they won’t directly get incriminating chat of somebody ordering drugs, but they can go nab the dealer and their associates with that info. Or they can have a group of key activists followed if they know that when messages between these people spike just before a protest happens.

Central servers basically. Funded by ex-meta people and endorsements from western governments (general “if it’s popular then it’s compromised” suspicion). Also it requires your phone number gathers things like contact info from the phone, even if one assumes the messages are secure. basically could be seen as relinquishing a list of potential associates…

I don’t think Signal is unsecure, in a sense. it’s just secure for nobodies or anybody who want to use it in non western countries against governments hostile to the west or being designated to regime change targets. I however don’t think it’s much more secure than whatsapp for an high profile pro-Palestine activist for example. It’s a privacy tool for some and honeypot for others depending how they relate to US security state and western governments. Whats better for an intelligence agencies than to have a control of the globally used privacy communication tool.

I’m still convinced that Signal is an NSA honeypot.

Probably depends how the companies responsible for opening backdoors in their apps and services would handle it. Would they use the same backdoors that they give access to authorities in other countries or will they create a super specific backdoor just for EU.

unless the Finnish school system has bought into Chromebooks in a big way

Yeah goverment is now giving laptops students at that level, on a loan basis. Just so that everybody has access to free study materials that are now partly of fully digital. The computers are usually, but not always chromebooks because they are cheap and chromebooks are the “student laptop” anyways.

I wonder if the whole Secure Boot/Microsoft shim key issue is a part of this.

Yeah that’s part of it. The boot issues with usb. It’s apparently a total lottery of whose computer decides not to boot when the exam starts with the new windows limitations.
