How would an ISP block them, however? The only mechanism I know about would be DNS blocking, whenthe DNS server is supplied by the ISP.. Is there some new British trick where pages of certain sites could be selectively blocked? If so, how long before "politically sensitive" human rights pages would be blocked, or whistle blower pages?

CleanFeed, built by British Telecom to block access to child abuse imagery, sold to other ISPs, then inevitably abused as a blunt instrument to enforce copyrights. It's a two-stage filtering system: a list of IP addresses gets loaded into the ISP core routers, which diverts all access to those addresses through a proxy server; that server checks against a (secret!) list of prohibited URLs and lets the rest through. It has already blocked part of Wikipedia by mistake or misjudgement, and the government has already announced plans to filter "extremist" websites too.

TalkTalk, another of the named ISPs, bought a more elaborate setup from the People's Republic of China for millions of pounds, and push their "adult" content censorship system on all customers who don't specifically opt out. It's been a big political issue lately, with the current government wanting to force all ISPs down that route so you'd have to ask your ISP specifically to stop filtering your connection.

Anyone who encrypts mail to me does it from their own machines. This is for Facebook mail to you. If a user grabs your keys they can also send you mail directly without going through Facebook.

Facebook lets you control your public keys as if it were any other information: public, friends only, etc.

Just added my keys. Not that I care about the notifications that "Billy scored X on Y Game", but anything that obfuscates and encrypts data on the wire is a good thing. It's not just the NSA, how many of you use gmail? This will keep them from scanning your mail.

>In fact I may enable a bunch more useless notifications and set up a rule to delete them at my end as they arrive.

AC is great for long distance and certain applications. DC is great locally. The bridge rectifier should be between the grid & the home battery, not between the home battery and the devices it is recharging and/or powering.

The exception to this are high power home applications: Stove, Oven, Microwave, Toaster, Fridge, Dryer, Washing Machine, Dishwasher. The battery charger can be on the same circuit set.

Note that TV is NOT on this list. All video screens can be low power these days. All lighting can be low power. There is no reason why this can't be a simple 5V, 4A circuit with USB compatible plugs, several to a room.
