Overall responsiveness doesn't make any difference if you add swap to a machine which has enough memory in the first place.
System stability is worse without swap because when you do run out of memory, *random* processes are killed as they attempt to allocate RAM. Those processes can be *anything* running on the box, not *just* the memory hogs. Everything else does not keep running.
It's N times as hard to run out of memory while running with swap, because you have N times the amount of memory.
For the uninitiated. Swap is like a spare tyre. It's something you should have, but something you should try not to use except in emergencies. If your system is paging, add more RAM and allocate it to whichever applications need it.
The difficulty with desktop systems is predicting the usage, how big is that email, what happens when you open a 200Mb powerpoint. Therefore swap is required.
Sorry, I'm incorrect. Solectria have vehicles with 250 mile ranges using NiMH batteries and have a prototype car which will do 370+ miles on a NiMH battery.
With the increased energy density of LiON batteries that increases to 400 miles and 600 miles respectively. With Li-S batteries that would further increase to 800 and 1200 miles, though I would suspect they would limit the range to 400 miles and reduce the size of the battery in proportion.
Ah, no. You won't get a 300 mile range with a NiMH battery. You need a Lithium based battery for that. The battery cost is purely down to the manufacturing capacity.
Um, yes there are. You didn't mention which electric powertrain, there are several battery technologies.
The APC Tzero for instance. 0-60 in 4 seconds, 300 mile range on the motorway with LiON batteries, more than double that when Li-S arrive in a year or two. The batteries are expensive, but that's only for now, and they can be traded in and recycled, upgraded even.
I think you forgot to factor in the massive inefficiency of the petrol engine. The fact that an electric vehicle doesn't need 10k mile services, uses domestic power to recharge at a fraction of the cost of petrol.
In America, but tomorrow it might be nuclear, solar power, wind turbine, geothermal etc. Denmark for instance gets 10% of it's power from wind energy.
With a battery powered vehicle you can switch the supply to another generation platform by sticking a solar panel on the roof of your house and flicking a switch. Can't do that with Petrol, ethanol, methanol, hydrogen.
to completely ignoring the law entirely. Have you ever driven in Italy?
I was once driven back to the airport in a taxi where we *overtook* a police car which had it's lights and horns going. Went past it like it was standing still.
Newspapers, TV, radio, film it isn't at all surprising that he thinks copyright infringment should be considered a criminal act rather than a civil one.
Oh, and he's being prosecuted for attempting to bribe a judge. He had a law passed which would give him immunity from prosecution while he was in office. It has since been overturned.
Did I forget to mention that he's the Prime Minister of Italy?
1: Charge from domestic supply. 2: Charge from PV on the roof of my house. 3: Upgradable range. You can get 250-380 miles from NiMH batteries, LiON and LiS should improve on that. 4: Acceleration, peak torque at 0rpm. 5: Servicing costs.
You can park the Smarts sideways as well. It makes pulling out simple.
I was surprised by how large they feel inside, I expected it to feel cramped but doesn't at all, they just chop it off after the driver and passenger seats.
I'm also surprised at how long it's taking for them to be available in the US. You can get them in Canada.
All the clothing is completely waterproof these days, thank you Gore.
Backpacks, tank bags, tail packs, panniers, top boxes. You might be surprised just how much crap you can lug around on a motorbike.
They occasionally run a "Commuter Race", a man vs car vs tube vs bicycle vs motorcyle race between 2 points in London. The motorcycle wins every time and it's not just marginally quicker, it's 50% -> 100+% faster than all of the rest.
The idea is that you have a normal car *and* one of these. Much like the Smart cars we have in Europe. I have to say I don't see the advantage. You're still going to get stuck in traffic. I do think they should install short range radio in all cars as standard though so that you can shout at the twats in front of you.
Rather than a big car and a small car I have a car and a motorcycle. Use the bike to commute, swish through traffic and use the car for carrying stuff and longer ranges.
A Solectria Sunrise would be a much better vehicle to be aiming at:
http://www.evuk.co.uk/hotwires/rawstuff/art24.ht ml
Yeah... 1997... It can actually do 375 miles on a single charge.
No, I'm not falling into that trap, because it doesn't exist. Christ I can't believe people keep coming up with this "you already have half a dozen ID documents so why does it matter" argument.
If you have my credit card number, what do you know about my library usage? My driving habits? Do you know my loyalty card number? Sweet fuck all is what you know. To monitor me, you have to find me in all of the various different and incompatible indexes used by dozens of organisations. Not impossible, but decidedly non trivial. If everything is indexed onto a single number (and that *IS* the goal), it becomes trivial. You and I can be monitored in real time from anywhere in the world. Buy access to the offshore supermarket loyalty database and query my ID number (you know, that thing I have to present all over the place), bam! You know how many sheets of toilet paper I use when taking a shit.
There's a nice Iranian bloke owns a corner shop 80 feet from where I live, among other things he supplies halal meat, I shop there regularly, does that make me Muslim?
And no, I'm not suggesting that it will *lead* to dictatorship. ID cards are by definition a tool to allow discrimination. Dictators just find them extraordinarily useful when they decide which ethnic group they want to commit genocide upon.
The government is only one of the sets of people who will have access to your information.
I *am* working within the system to protect my privacy and liberty. I'm opposing a national ID card scheme. Britain has the oldest democracy in the world and it has functioned more or less acceptably for 800 years without a National Identity Register for all of that. I am lobbying my MP, he knows I won't register and that I'll be campaigning against him at the next election.
If you have my library card number, what can you find out about me?
If you have my driving license number, what else can you find out with that number?
If you have my passport ID, what else can you find out about me?
If you have my national insurance number, what else can you find out about me?
If you have my national ID number which indexes *everything*, what can you find out about me?
It isn't rocket science. A single index makes monitoring, investigation, stalking even of individuals trivial. By anyone who can afford access to the databases, and most of the databases will be held by private organisations. They'll also be located outside the country to evade the data protection laws.
Governments change. Germany wasn't always a fascist state, it was a democracy prior to 1933.
"very modern country needs to keep track of its citizens for various things, from banking to medical insurance."
Eh, no it bloody doesn't. The government in the UK is a public *servant*, that means I am their boss not the other way round. You might be quite happy on your leash as the property of your government.
"Yes, the ID card lets people gather up all your data in one tight bundle, but that can be done with or without an ID card."
Um, no it can't. That's the whole point of the card... To allow this.
Spain has compulsory ID cards and they have 800,000 illegal immigrants from Morocco. How exactly have the cards stopped these immigrants?
The only reason Belgium doesn't have an illegal immigration problem is that they saw the place and decided not to stay. They don't seem to have a big problem comming through Belgium when heading for the UK.
BTW, the proposed UK legislation won't require you to carry the card, but you'll have to present it within 7 days when stopped by the police. How fucking stupid is that?
"Yes officer, my name is Ben, Ben Dover and I'll pop down the station on Monday with my card."
Identity based benefit fraud is around 5% of the 4 billion per year. The rest of the fraud is "misrepresentation of circumstances" according to the DWP. This is people claiming that they are unemployed while actually being employed for cash in hand or claiming housing benefit while owning a house or "renting" from relatives etc. You get the picture.
The ID scheme itself will cost more to administer on an annual basis, around 250 million per year.
Yo, Moron. I've already had this discussion with another moron who made the same comment.
Did you know that the prison population in the UK is around 90,000, in 140 prisons. Building enough prisons to host a million people is going to be *fucking* expensive. They cost around 90 million each and you're going to need around 1,400 of them.
You're an idiot who hasn't put a second's thought to the subject but figured they'd just blurt out their ignorance for all to read anyway. I'm not surprised by the AC.
An ID card gives all information about you a single index. All you need is an indidividual's ID number and there's absolutely no technological reason you couldn't monitor their activities in real time.
"Speculative or implausably apocalyptic"? WTF? Don't you know *any* history?
Germany, 1938 6 million jews were executed by their government. The jewish people had "J" stamped on their identity documents. It's how they knew who to kill.
Rwanda, *TEN* years ago. 800,000 men, women and children with "Tutsi" marked on their ID cards were *butchered* by their government... With machetes.
Governments change in the blink of an eye:
Pakistan, 1999 a military coup took 17 hours. Iraq, the fall of Saddam took a week and that was an outside country. Greece, 1967. Portugal, 1974. Fuck, there was a coup attempt in Spain in 1981.
What planet do you live on? One where the CIA didn't help overthrow the democratically elected government of Chile and install a military dictator?
All these things *actually* happened. If you give the government the tools they'll bloody well use them.
"solar cells still collect juice on slightly cloudy or overcast days, but this method doesn't work nearly as well."
In fact the reverse is true. Infra red penetrates clouds better than visible light so even on cloudy days you can still generate. You simply size the field of mirrors to account for lowered sunlight.
Solar II uses large tanks of hot salt and stores the heat for generation during the evening or very overcast days. It's a far cheaper and more efficient way of generating electricity than photovoltaic cells.

The problem is when you have 512 Mb of RAM and some twat sends you a powerpoint email giving you 513Mb of running applications.
