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.
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.
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
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.
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.
I half expect the next move will be space-based datacenters. I can imagine twitter's new owner seeing the benefits in hosting entirely outside the jurisdiction of any government.
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.
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.
True, though there's also the general absurdity that you can trademark a single letter. Surely meta have the best case as their trademark is actually for social media use, but even still it doesn't look that similar
So CA is a bit different. The state rules require the premium be priced basically looking back at the last 20 years of actual sustained losses in the area. That seems like a good consumer rule to prevent price gouging but State Farm are (probably quite reasonably) saying that with the increased risk due to climate change and the increased rebuild cost, they can't square those numbers.
I do wonder about Farmer's decision though, because as I understand it, in FL, they aren't similarly restricted and could price their policy however they need to balance the numbers. Perhaps PR-wise it's easier to leave the market than double everyone's prices. It's definitely a vicious cycle though, as more insurers leave the market, this risk will get concentrated on fewer and fewer players and their catastrophe models will show their increased risk and so on..
I have that sense too, i feel like some of my earliest interactions blew me away and now i still use it for certain pieces of code, but it's not as strong as it first was.
My parents lived with the threat of nuclear annihilation, my grandparents fought in ww2. My gg parents lived through ww1. Most of everyone before them lived in relative poverty.
I'm not sure id take any of them over the current situation. Certainly there are massive problems looming that will cause lots of suffering, but humans do find joy and purpose at all times
She's definitely in trouble, but I'd wager that most of Frisch's haul has come from out of the district. He certainly seems like a good candidate, but I think higher turnout in a presidential race will give boebert a good shot at it.
