    This isn't really the same kind of bug. Those bugs made instructions emit the wrong answer, which is obviously really bad, and they're really rare. The bugs in the article make instructions take different amounts of time depending on what else the CPU has done recently, which isn't something anyone would notice except that by asking the kernel to do something and measuring the time to execute affected instructions, an attacker that only had usermode access could learn secrets that should only be available to the kernel.

    Sure, the internet is more practical, and the odds of being caught in the time required to execute a decent strike plan, even one as vague as: "we're going to Amerika and we're going to hit 50 high profile targets on July 4th, one in every state" (Dear NSA analyst, this is entirely hypothetical) so your agents spread to the field and start assessing from the ground the highest impact targets attainable with their resources, extensive back and forth from the field to central command daily for 90 days of prep, but it's being carried out on 270 different active social media channels as innocuous looking photo exchanges with 540 pre-arranged algorithms hiding the messages in the noise of the image bits. Chances of security agencies picking this up from the communication itself? About 100x less than them noticing 50 teams of activists deployed to 50 states at roughly the same time, even if they never communicate anything. HF (more often called shortwave) is well suited for the numbers game. A deep cover agent lying in wait, potentially for years. Only "tell" is their odd habit of listening to the radio most nights. All they're waiting for is a binary message: if you hear the sequence 3 17 22 you are to make contact for further instructions. That message may come at any time, or may not come for a decade. These days, you would make your contact for further instructions via internet, and sure, it would be more practical to hide the "make contact" signal in the internet too, but shortwave is a longstanding tech with known operating parameters.

    This would be better suited in some casual ranting community. Or one concerned with tech bros. I think it's completely off topic here.

    I’ll probably never trust anything they’ve touched until I’ve taken it apart and put it back together again. Me too. But the vast majority of users need guardrails, and have a different threat model. Even those that also care about privacy, if they just want a solution that comes by default, this adtech 'fake' or 'superficial' solution does provide something. And anything is more than nothing.

    You do. But you also plan in the case the surrounding infrastructure fails. But more to the point, in some cases it is better to produce (parto of) your own electricity (where better means cheaper) than buy it on the market. It is not really common but is doable.

    Outlook.... Ok Pretty solid Bahaha hahahahaha Sorry. Outlook is a lot of things. "Gooey crap" would be one way to describe it, but "solid"? Yeah, no. Gmail is (well, was) pretty solid. There are a lot of other webmail providers out there, including self hosted options and most are pretty solid, yeah. Outlook, though? It's a shit show, it's annoying. Do you love me? Please love me, please give feedback, please give feedback again, please look at this, hey am I the best? Am I.. STFU YOU PIECE OF CRAP! Can you PLEASE just let me do my email without being an attention whore every hour? Even down to the basics. Back button? "What is that? Never heard of it, can't go back to the message I just was on because I'm Microsoft software and so half baked." Having two tabs open? "Oh noes, now I get scawed, now I don't know how to manage sessions anymore, better just sign you out everywhere." What is it with Microsoft and not being able to do something basic as sessions normal? I'm not even asking for good, definitely not "awesome", just normal, and that is already too much to ask. Try running it in Firefox! I'm sure it's totally not on purpose, just "oopsie woopsie poopsie" accidentally bwoken. Maybe it's working again today, who knows, tomorrow it'll be broken again. I run everything on Firefox except the Microsoft sites, they have to be in chrome because fuck you, that's why. Seriously, I can't take any Microsoft software seriously at this point, and all of it is on its way out in our company, I'm making sure of that
