A small UPS will often have the equipment running directly on AC input power and only switch to the battery if the input power fails.

The device can identify itself with a UUID, which isn't key material and doesn't allow anyone to break the channel between the actual device and the server, which is still authenticated by the client using the server's public

Nope, the client device only needs the server's public key, which isn't a secret. The session keys are a secret but they're also different for every device, transient and never written to permanent storage.

You should see what some of the other alternatives do. I just decommissioned a server and pulled the drives out of it. One of them had SMART data indicating that it reached the "drive failing, replace now" stage six months prior.

A lot of this depends on where we want to go from here, too. If you use traditional UDP DNS, it's one of those things the C10k folks love to show can be handled by a Pentium III. You could probably get a single modern server to handle

We recently had a big wind storm. Trees down everywhere, power went out. Fine, whatever, start the generator and it's back to being Tuesday. Wasn't just the power, also Comcast. Fine, whatever, tether to my phone. Wait, no service

Also kind of odd because messaging apps use a trivial amount of data unless you're doing video. But most people may not know that and then switch to them for "unlimited" and there you go.

Not only that, it would allow SEO companies to sign up as "news organizations" and then use the knowledge gained about the ranking algorithm to fill everyone's search results with SEO spam even more than it already is.

But Mozilla isn't either. That's the trouble. They make plenty of money from Firefox but then don't spend it on Firefox, so Firefox market share declines, so they make less money from Firefox. Maybe they should try turning th

I don't think it's any harder to create a website than it ever was. The problem seems to be that corporations have made it so easy to do it within their silos that people aren't willing to spend ten hours on something they

But isn't the middle ground requiring copyright assignment and then dual licensing? Oh dear, your company's lawyers are afraid of the AGPL? Well then pay the project for a commercial license.

There's also the matter that they keep adding things to the list. Remember three years ago when we didn't know we had to worry about Spectre?

Does anybody make a reasonable 16:10 aspect ratio 4K monitor yet? Because I'd buy it, but I can also stick with 2K forever if nobody wants to shut up and take my money.

You're making a lot of assumptions there. It could be that example.edu/financial-aid/ is just information and PDFs and doesn't have any sessions or cookies. Or the real financial aid system is on another domain, but
