  • I see a lot of people talking about specific parts of 5G but honestly most of them are optional and only some of them will be active at once.

    “Regular” 5G uses the same frequencies as 2G, 3G, etc. The carriers will be moving more frequency ranges of older Gs to 5G as time goes on.

    In general, we can send more data at once because we have better math for sending data. There’s not really an ELI5 that can explain that part besides more math.

    Another part is there’s also more math so that the phones can take turns talking better or split up frequencies better, so they don’t have to re-transmit as much.

    If you’re in hyper-crowded areas, they made a new frequency range that cannot go through walls, but is way faster than the regular ones that we’ve been using. It’s only good for like sports stadiums and stuff, and you almost never use this. It’s called mmwave (millimeter-wave) and you can safely ignore any marketing around it. Not many phones support it yet because it’s useless 99% of the time.






  • It still defends against one failure mode (the website gets hacked but you’re ok) but yeah, obviously if you get hacked and the hacker knows how to get your vault out then you’re 100% screwed.

    My suggestion is always hardware 2FA, even though it’s not as mature as the other systems. Personally I have two Yubikeys (in case one breaks/gets lost) but it does mean that I need to add TOTPs to both of them each time I add a new 2FA.







  • Yeah, I still can’t figure out what sort of mentality makes that seem like a good idea.

    For Musk there’s at least a chance of some sort of thought process going on there. Narcissistic people tend to think that everyone else is just like them (although maybe a lesser version of themselves.) Musk has had a very serious addiction to Twitter for a long time, therefore everyone has a very serious addiction to Twitter, therefore we can charge people a ton of money for their Twitter and since they can’t leave they’ll have to pay for it. And legal repercussions? Why, he’s never seen those in his life!

    Maybe spez is the same, just with a bunch of alt accounts so that he can post in /r/jailbait or whatever. I can see why he might want to turn reddit into 9gag if that’s all he’s ever used it for himself and isn’t capable of understanding the concept of other people having different uses for it.

    But at some point he must notice that it’s not been going well? Right?
