@ Mark Haven

"The savings quoted are based on a lamp being left on constantly - this almost never happens in real settings. When you switch them on and off each time the reactive load uses a lot of energy."

Do you not watch MythBusters (OK, it was repeated a couple of days ago and I happened to catch it, but they tested a variety of bulbs.

Startup does cost more energy, but it's negligible - the WORST performers were full size fluorescent tubes, which took the equivalent of leaving them on for 26 seconds to start up.

So if you leave a room to make a cup of tea - even with the worst performing lights you're best switching them off.

It's been a long standing rumour, but it was easy to debunk on the back of an envelope:

Lighting circuits are fused at 6A in general in the UK, so you can't get more than a kW or so anyway. To use several hours worth of energy in a few seconds would require much more, e.g:

10W bulb.

Aiming to use 2hours worth in 10 seconds:

7200/10=720 times the power

7.2kW ~30 ampere (through a 6A fuse/trip switch)

~2.5 kettles!

it's not going to happen

One wheel drive did quite well

No need for four wheel drive, or has everyone already forgotten about the African Top Gear.

I managed to cycle to work - 10 miles in the snow was fine, my glasses froze up again, but that's OK - I can still see around them.

Amazingly, this afternoon there seemed to a mass exodus from the building when it looked pretty outside, and people sat queuing for 45 minutes to get out onto the roads - meant it was nice and quiet when I left though.

@Perpetual Cyclist - Safer on the road IMHO, I tried a cycle path for about 20 yards, but the council don't think we need grip - so there's no gritting of the cycle paths (even right alongside the road)

Muppets

Why are they so inept?

I can't imagine that anyone with enough brain power to put on their own underwear would think that a 4 year cycle for a security review is just ridiculous.

Not a bad system...

They do a basic set, use a couple of easy libraries to get a quick release out, then go and rewrite those as they're dodgy and non portable.

Just hope that v2.0 is actually properly portable - get them to drop mac/linux v1 ideas and do it with v2

I like Chrome on my VM, but don't like having to fire up a VM to use it, so it's only rarely touched.

SSL proxy

Surely the capacity to generate your own certificates allows an SSL proxy, that's massively valuable. I don't need to set up a fake bank site, I just proxy your SSL connection and read your login details.

The returns from that (especially if you combine it with a DNS poisoning attack) are potentially massive. I think that criminals would probably know that, and would assume that they've been looking at this quite hard since 1996 (and then again when the MD5 vuln's were disclosed, assuming they hadn't already cracked it privately).

I want...

They've even managed decent resolution on both screens. It'd stop me having to switch my screen resolutions around any time I need to move around the office...

but £2k?! That's a steep price, even for a decent machine, the engineering in that second screen really does need to be something special to justify that kind of an outlay.

Breasts have been sexualised...

For some reason it is now assumed that nothing can perform more than one function, I think this is because we've all been dumbed down to the point where so few people can think of even one thing at a time that it's a reasonable assumption.

Yes breasts do perform sexual functions, but they also perform other functions. Do you let your child read, because they could read porn if you do.

Quote from a midwife friend:

"Breasts, like women, can multi task"

Great internally

But externally there are much better noises to simulate than a V8.

Those new broadband noise generators being put in sirens for instance, not in the same pattern obviously, but at low speed it might prove useful for cyclists (who would need to be owls to look for these cars). It's really rather useful for cyclists to know when some idiot is coming up behind them.*

* Yes I'm a cyclist, no I don't listen to music while I commute, yes I do try and watch out for vehicles and assist them by indicating when there is no approaching traffic (i.e. when it's safe to overtake) as I can usually see round the corner first...

If thats a real boot time then woohoo

Why hibernate if the boot sequence is 5 seconds (I know, you get to keep your documents open - seriously how many do you work on?

I'd love a machine that booted that fast, I might even turn it off overnight. Shame most POST sequences take longer than that...

Security

No problem, all terrorists use Vista, and MS will simply add a back door.

Of course anyone using *nix is a terrorist and should be locked up for 42years unless they provide the root password and access to their bank systems.

Need an ATV with a robonaut

Hubble is low enough for comms to be pretty quick. A quick ATV trip could have load of fuel up there to keep hubble in the sky, as well as a permenant robonaut for sensible repairs.

Heck - having a couple up there all the time could be a good way of fixing anything - given time chaning orbits is the cost, not waiting to catch the errant sattelite, and IIRC the ATV had a pretty good load capacity to LEO

Decentralized

Add some VPN and decentralise it all you want, just make sure that there are some well defined standards for data interchange (note, not storage - interchange) probably XML with a certain number of required fields for any consult etc.

I do want my records held locally, but when I get airlifted to a distant hospital because some idiot in a car can't wait 20 seconds to overtake me on my bike then I damned well want them to be able to access that data in a comfortable format.

It should be possible to determine where my records are kept (and where they have been sent to when I moved)

Your fevered imagination

"Could we imagine a server world in which apps ran directly under ESX and there was no guest OS at all - or is this my fevered imagination running riot?"

So that would be an operating system then...

ID cards are important

Just take our word for it and don't ask why.

And stop coming up with reasonable objections, our inability to talk about them makes us look bad.

DRM has only ever affected paying users

I buy a DVD, I have to watch a "you are a thief" propoganda.

I copy it to HDD / DVD to keep the original safe and I can just plug the disk in and watch the film.

DRM will always be cracked, just make it sufficiently unattractive to crack and most people won't bother.

shortet here...

"All overhead cabling must go. It's the dumbest thing in the world - ugly, dangerous, and keeping it maintained (here in the States anyway) is responsible for over half of a utilities annual budget."

Overhead cabling here is normally quite short - in most towns it's only a few metres, even in small villages it tends to be only tens of metres.

There are some significant lengths, but they are fairly uncommon and often well protected, nothing like the sprawl encountered in the states - we just don't have room to make that much mess ;)

Fool

Stick with growing with the economy, although I can understand that that might not seem attractive at the moment.

Although if we're in a recession (-ve growth) and the carriers grow with the economy, how are they managing 3% +ve growth?

closing speed

"Quick (stupid) question for the Register's boffinish readership: if each beam is travelling "close to the speed of light", what's the closing speed of the two beams?"

From the perspective of each beam the closing speed is slightly closer to the speed of light.

From the perspective of the detectors (and us) the closing speed is twice "close to the speed of light" (i.e. close to twice the speed of light)

Both will release the same energy (thanks to Einstein for working that one out), which is fun, and similarly energetic collision occur frequently throughout our solar system, and the rest of the universe...

Why not cooperate?

With China and Russia and the EU and just build a decent rocket that can do lunar and then martian exploration?

Oh, because you want to try some willy waving.

I think we all need to grow a pair and cooperate to the moon at least.

Commercial orbital systems are being developed and should be working well soon, then the market can go for lunar missions - they'll have a target if we have a lunar station in place.

" I have actually been quite happy with the service I've had from TalkTalk.

But then I was with BT before, so what do I know? (well, other than I won't be going back to BT until they drop their prices, dump Phorm and actually listen to me when I call them...)"

Umm - Talk Talk are in bed with phorm as well...

Thumb Up

My Toshiba got thrown down the stairs.

With the screen open and the machine running - it fell from about 10 feet onto a laminate floor (causing a minor scratch on the floor), landing on the top corner of the screen (pretty much worst case I'd guess).

The screen casing split down the side, and cracked at the corner. The metal brace contorted into an S shape.

But - NO dead pixels on the screen, NO reallocated sectors on the HDD.

It's absolutely fine (other than the cosmetic damage).

It's still here working away.

I'll go back to toshiba any day, dell managed to not be able to send me a laptop - every time they managed to have something different out of stock... even when I phoned them and checked what was in stock!

Physical Ebooks

The game boy et al model seems to be hopeful for me.

Simply have a pair of "sockets" on the device and use microsd sized cards, you could do a complete works card, or a single book.

Then you can share the cards.

Of course you need a drawer in the device then as well...

95 years?

So if I write a song at birth I'll still be needing income from it when I'm 10 years dead?

Surely 20-25 years is enough time to make a profit from a song, "artists" manage to crank out alot of "songs" each year.

Books are a different matter - they take a long time to produce, and can't be replicated in any sensible way (a book cover is quite different)

Software is a different matter again - if you haven't released an update in a few years...

@Tim Spence

"Yes, I too posses the ability to knock a few zeros off a number, but the point is, why should I? Why list something's weight (sorry, mass) in x millions kgs when there is a larger better unit available, which shrinks the number to something tangible.

Going by your logic they might as well have listed it in micrograms? That would be 7,700,000,000,000,000 µg. There, easy isn't it. How about yoctograms? That makes it 7.7e+33 yg. Oooh yes, much clearer."

Well the kg is actually the SI unit, so makes the logical choice. We are talking about a scientific organisation (well, one with scientific roots at any rate).

What's odd is that the SI unit is the only one to require a prefix. We should redefine the gram to 1000 times its current value, and maybe rename it for simpletons. Then the SI unit would be a "proper" unit and not a multiple.

TBH I'm happier knowing how many zeroes I'm dealing with - maybe 7.7E+6 kg

PalmOS and I'll buy it.

Especially if it can bridge between those connections - easy WiFi for the laptop (and the wife's obviously)

My last WM phone used to crash when receiving calls - the screen would turn on - say "So and so is calling you", the ringtone would play (endlessly) and the vibrate would stay on (rather than pulsing like it's meant to). If you pulled the battery it would reset. then you could call them back.

Windows isn't coming to a phone near me ever again.
