Even if it's powered, RAM will lose its data on the order of a tenth of a second. RAM doesn't just require power, it requires that your computer constantly read and rewrite it - so every 64ms your computer has to read every gigabyte of RAM and write it back.
Yes - it's been the job of the DRAM controller for almost the entire history of computing. But that's still a part of the computer and if it stops working then your RAM will go blank in a fraction of a second
Some very early systems did do it at kernel level, but yeah you are correct. Though I'd also consider the dram chips to be part of the computer and DRAM refresh makes up a good part of your phones battery consumption at standby.
From what i've read it's temperature dependent, and at room temp some dram cells might take as long as 10 seconds to decay. The 64mS refresh is a super conservative call because it's really bad when random bits go missing out of memory. The decay is faster at high temperatures, but some dram controllers might actually adjust based on temperature.
It's the right play politically. Consider if the roles were reversed.
If Bernie Sanders was arrested for breaking into Walmart headquarters and demanding they unionize, he'd absolutely say something like "It's not about breaking the law, it's about standing up for the millions of Americans who are struggling to make ends meet while the Walton family continues to amass wealth. That's what this is about. It's not about me, it's about us."
His supporters believe in his cause and they'd absolutely eat that up. I can understand why people support unionization and don't really get why people are so into thuggish authoritarian rule - but if that's what gets you up in the morning, then seeing Trump admit to this is surely exciting.
Maybe that's extreme, but i could totally have imagined him chaining himself to oil refinery gates or similar shenanigans (at least when he was younger).
I was trying to make the point that if you believe in a politician's end goal, then the means are often justified. Trump's supporters (for the most part) don't want to see him weasel out of this by saying he didn't try to subvert the election, they want him to say that it was imperative for the country that he do what he did, laws be damned.
I doubt it's the best legal defense, but realistically he's going to either be re-elected and pardon himself or he'll drag this out until he dies. I don't see any world in which he's likely to wind up in prison.
But if you do believe that Trumps end goals are laudable, then you are of course going to believe that it's justifiable that he'd break the law to achieve them.
There are, undoubtedly, millions of people in this country who believe that thwarting the peaceful transfer of power is a small price to pay for their authoritarian dipshit leader... and it makes sense that he'd play to that population.
I was trying to come up with a hamfisted analogy and clearly missed the mark.
I'm pretty sure Bernie has actually been arrested at civil rights protest, so that's probably a better example. I actually think that makes him more qualified to be president.
Presumably trump enthusiasts feel similarly about his mounting list of felonies. I think that should immediately disqualify him from being considered as a candidate, but a lot of people obviously don't and I have to assume that's because they believe in authoritarian psuedo-dictatorship in the same way I believe in civil rights.
I read it as an analogy elsewhere that made a lot of sense to me.
I'd personally love to see trump in an orange jumpsuit for the rest of his life. However I genuinely believe that he'll manage to convince millions of people that his means justify his goal.
It's easy to look at the string of charges and indictments and assume he's unelectable, but a lot of people are going to look at this like it's a legitimate form of civil disobedience. I'm not, in any way, trying to suggest that his actions are comparable to "unlawful" climate protests or civil rights protests. But I do think he's posturing to make that claim and continue his narrative of persecution.
I also see a lot of gloating among the left wing that "haha, even trump's lawyers admit he broke the law" like that means anything at all. This is a calculated move that tries to control the narrative and play into his delusion that he's a poor oppressed hero who won't give up the good fight.

But the cool thing about open standards is that there's a clear pathway to creating an everything app. Especially if decentralized ids gain some traction, then we could have an app that combines mastodon and pixelfed but presents the different posts in a sensible way.
I can't really wrap my head around what such an app could look like, but it's much more feasible to build one than it would be with closed services. I'm hopeful that freedom to experiment without lockin will lead to some really neat ideas

I have a synology NAS where I backup my photos to. What would be the most cost effective way to encrypt and back up this data without having to purchase another NAS and install it at a family member's house. It would be about 5 TB and would not touch the data unless my NAS completely takes a crap.
If you want to keep it wired then you'll need to put it on a separate VLAN from your other devices. A VLAN effectively allows you to create separate ethernet networks over the same physical network. We use them at work to keep factory hardware separate from office hardware and I use them at home to keep a vpn open for streaming geolocked content from another country. Traffic between the two VLANs has to be routed just like it would if they were separate physical networks.
I have an Edgerouter POE which has a small built in switch and supports VLANs so I can easily dedicate a port on the switch to a particular VLAN. In my case I route that traffic through wireguard, but in your case all you really need is setting up NAT for internet access and not route it with your other VLAN.
Any commercial grade routers support VLANs, i've seen it on unifi, aruba and fortigate and have never heard of it not being supported.
As others have pointed out, if you have a switch between your TV and Router then that'll need to be a managed switch that can trunk the vlan code back to the router, otherwise all the traffic will be comingled.
Other thoughts:
You might be able to arrange your IPs to sort of fake it. If your router is 192.168.1.1 and you make the TV be 192.168.1.2. Then you could give your TV a static IP configuration and tell it that it's subnet mask is 255.255.255.252. Then it'd only consider the IPs 192.168.1.1-192.168.1.2 as being in it's local network and if it tries to access something else on the LAN then it'll send it to the router for forwarding.
I'm not sure what your router would do in that situation, but it seems unlikely it'd manage to forward that packet. You'd have to avoid putting any device on 192.168.1.3 (as that'd be the routers broadcast address) but I think you could probably make that work. It's not really secure (as anyone that compromises the TV could change the subnet) and it'd still be possible for devices on your network to send UDP packets (but not get replies from) the TV. It's also not really extendable and you probably can't get a second TV to work like that (and definitely not three), but it wouldn't require switching to commercial routers.
The switch on its own will do nothing for you. It's only useful with a router that supports VLANs
Unfortunately in your situation you'll need to replace your current router-modem combo with a dedicated modem, a commercial router (if you don't want to build your own linux one then EdgeRouters seems pretty good value for money) and a managed switch.

“It boggles the mind that people would believe in this stuff, but if you put yourself in the minds of the Plowshares people, this is progress, this is modernity, this can be done,”
Maybe i'm just cynical, but I always sort of thought this was something of a smokescreen for nuclear weapon development. I have a hard time seriously believing that they thought we'd really want to use nukes to mine rock or that we could dilute radioactive natural gas enough to burn it in our homes. I always felt it was a politically convenient way to funnel even more money into nuke development.
As I understand it, the super high resolution satellites have to be super large because you run into optical limits on the lens structure. The Maxar 30cm resolution ones are the size of a small school bus.
While there's probably a market for imagery that's low resolution and ultra-fast refresh, it'd still add mass and complicate things and starlink is already a complicated project.

Maybe it's a long game to well cybertrucks to people who want to own the libs, but it feels shortsighted. I seriously expected my next car to be a tesla but cant support this shit
I suppose it's strange to reach a point where I have 3 choices for gigabit and multiple much faster choices and not opt for the faster. This is literally the first time in my life that I've not had the fastest plan I can get. I can absolutely afford 10G service... But you are right, there's really no reason for it right now
Why do SSDs have a more limited number of times data can be written to them, but RAM memory can handle loads of re-writes?
In a similar vein, why can we not use the technology of RAM to prolong the life-cycle of an SSD?
