You could take care of some of the daytime failures with solar (and evening if you get some batteries).

Be aware that for a solar installation feeding power into the grid, you are generally required to have a control system which immediately shuts down your solar generation if the power grid fails. This is for safety reasons (chaps working on the line don't want to find there are still unexpected volts there after they've shut off the supply) and because your system will start to go blue in the face very quickly if it tries to power your entire neighbourhood.

You could have a more sophisticated control system which merely disconnected you from the grid and powered your local devices, but that would of course require some storage of power as well because your load would practically never match your generation. The vast majority of small solar installations do not do this.

I found a while back that GMail started flagging e-mails from my server as spam, even for a business customer who had explicitly white-listed my server in their configuration. Setting up DKIM message signing cured that.

Yahoo on the other hand are complete fuck-wits when it comes to spam detection. I've tried in the past to follow up random spam flagging, and they just give you the runaround. I filled in a complicated form with full details of the erroneous spam flagging, and they responded with a request to send all the same information again to an e-mail address, and then when I did the notification bounced because the e-mail address didn't exist.

The only thing you can do with people who use Yahoo for e-mail is teach them how to look in their spam folders. When they do they'll find lots of other non-spam there too. That's the moment to suggest they move to a proper e-mail provider.

Because most people sit WAY too far away from their TVs - even 720p is "retina" resolution - increasing resolution does absolutely zip because they can't even resolve the added resolution.

A rough guide is about 1:1 screen size for 1080p

Way too far away from their TVs for what? If your criterion for deciding the correct sitting distance is whether or not you can tell 720p from 1080p then perhaps you have a point, but if the object of the exercise is to watch television in comfort then 1:1 is just silly.

Thats how the internet is paid for. The sending provider pays the receiving provider for the bandwidth, and this is the only rational way it can be.

Really? I'm only an end user, but my experience is that the charging is the other way round. Traffic to me is metered (and I pay for) whilst traffic which I originate is un-metered.

Well, you could click on it for yourself (you don't have to place an order - just click the relevant radio button and then hit submit) but for those who want a short cut, the form then fails field validation with the following message.

"Sorry, for a censored internet you will have to pick a different ISP. Our services are all unfiltered."
