WOOSH!

The capitalisation thing is a piss-take on the tabloid press, eg the Daily Mail and its ilk. In general The Register doesn't take itself very seriously.

No, I don't like the LH anti-CC articles very much, but he seems an OK guy except for that large blind spot!

Disclaimer: I occasionally write for ElReg and indeed hope to get a free lunch out of that writing in a couple of weeks!

And what strain of paranoia makes you think that any of us in this thread want to "silence" you; that is wild talk.

We appear to be having an on-line civil discussion with no gun literally or metaphorically held to your head.

Currently I think that the clear majority of road users and funders don't want motocyclists (or others) with a rather strong sense of self-entitlement going at *unsafe* speeds around us, whatever those speeds are and whether or not they are related to the legal speeds. However, I haven't seen many public roads on which 154mph would be safe other than empty motorways in good visibility.

So go and get the rules changed, but the original question appeared to be in the present tense, and I answered it as such.

Actually, I think that speed limits are bad laws* but I'd still want people dinged for dangerous driving in that shared space whatever vehicle and speed is involved.

*I take the lead from my uncle who was a very senior and placid and respected barrister who as far as I know had never knowingly broken a speed limit, and had immense respect for (most of the rest of) the law of course.

Don't buy in to 'peak' anything if you can avoid it; nicer for you and nicer for (and cheaper for) infrastructure.

I pick my work hours (when I have a day job) so that I avoid peaks since I loathe them even more than getting up early which I then do instead.

And now I'm full time on my start-up I need not generally join the peaks either (nor travel nearly so much nor so regularly).

I disagree similarly with the rest of your assertions as being necessary at all. You assume them to be so, but they are clearly not so for everyone, and probably not so even for you. And we do NOT have to solve the problem for everyone with a single solution anyway.

Yes, same here. If I actually need a car journey I rent. There's even a Zipcar bay very close to me though I've not had reason to use it yet. I save myself the expense and trouble of owning, insuring and maintaining a car. I also have a much cheaper house from not having to pay for parking space nor even being right next to a road; I may have saved as much as £100k on my house purchase in fact, which on top of not paying for a car all that time seems like a huge bargain.

People already DO react to time of use pricing and it is in use in many places round the world at retail level and most places at commercial and industrial level.

One thing to note at the retail level is that typically not even the majority of the retail cost of a unit of electricity is the energy itself; infrastructure costs and so on are folded in too, so the price swings are a lot less dramatic than at the wholesale (or balancing) level which can range from 3:1 to 10:1 in the GB market for example.

The GB's best-known ToU retail tariff (sadly we don't have a national real-time one) is Economy 7, designed originally to soak up power at night from nukes that couldn't be turned down. (It's not only renewables that have stubborn timing problems.) I think the unit price ratio is about 3:1 between day and night. One third of domestic electricity use is on that or closely related tariffs, or 10% of all GB electricity consumption roughly. (The definitive source of this data is DUKES https://www.gov.uk/government/... .)

Average UK household use when I last looked ~3,300kWh/y.

Ours, ignoring PV, 1,500kWh/y (family of 4, end of terrace house).

I see a (cheap) solution...

However, we do generate a mean of ~10kWh/d from our PV also, down to ~1kWh/d in the depths of winter. A 4kWh battery would mean that we would not have to import from the electricity grid at all for 9 months of the year, only export. A complete inverter+battery system to cover us would currently cost about GBP8k. If we switched from natural gas heating to heat-pump (doubling our annual electricity demand, primarily in winter) that would still be about 6 months. We'd need a bigger inverter though.

I have my RPi B+ running all my Internet facing services and running off-grid in gloomy London at under 2W, nearer 1.5W when I can fix some transient issues.

http://www.earth.org.uk/off-gr...

And if I need something lower power I have Arduino-like boards that I run on microwatts, eg for battery-powered remote sensing.

http://www.earth.org.uk/out/ho...

I see all the complaining about memory and speed but as someone who grew up with a Z80- and 6502- based set of home computers, then used Sun Workstations with a few MB of RAM and tens of MHz clock, the Arduino/ATMega328P matches the Z80/6502s in performance at a millionth the power and has non-volatile storage built in, and the RPis are and order or two of magnitude better than the workstations and a couple of orders of magnitude cheaper.

I can fit almost all that I need to run with careful use of resources into the RPi/Arduino world and still have lots of elbowroom left over.

Yes, I've worked on big systems for (eg) big banks, but most of us really need GHz and GB on every machine? Some yes (like my MacBook), but most no.

That would be a very good step and eliminate most of the issue with Google, I agree.

However, G also insists on, for example, sending out G Calendar notifications forged with my sign-in email, which is SPF/DMARC protected, and which other systems (and gmail) thus entirely correctly often reject.

But I can't get anyone at G to even acknowledge the issue. (Would be nice if a Googler was reading this and would pass it on.)

And, BTW, G also seems to ignore email other than from the a/c's login address, eg for AdSense/AdWords, which is a Catch-22, and one small reason why I am using them far less.

DMARC would work a lot better if Google for one didn't wrongly try to internally forward as-is *and then bounce* email from DMARC-controlled domains, thus making it impossible for example to get through for many support queries, and causing spurious problems with (say) Google Calendar when the account ID is in a DMARC-controlled domain.

Left hand vs right hand Google? You guys are meant to be smart!

That and randomly chucking email from DMARC-controlled domains in SPAM folders...
