Canada Tops List of Most Science-Literate Countries

Mirar survey? (217 comments)

I can't find the original survey. Anyone that was able to dig it up?
How did the other 34 countries do?

New EU Rules Will Limit Vacuum Cleaners To 1600W

Mirar so 1h every 10 day per citizen (336 comments)

Denmark uses about 34TWh/year. EU has about 500M citizen. A vacuum cleaner is using about 2kW.
That gives about 30 vacuum-hours per year per citizen, or about 1h per 10 days (rounding in different directions).

Seems remarkably reasonable.

I don't understand the meddling of capping the power though. Just make sure everything needs to be marked with how much !/W you get from the items. I'm sure most consumers are interested in the actual work performed by the vacuum, not how much you put in. But the sellers are of course interested in hiding it.

(. Soon they will cap your hifi at 40W and tapwater taps at 1dl/minute. .)

Driverless Buses Ruled Out For London, For Now

Mirar Re:Driverless trains (84 comments)

I find this the most interesting comment in the thread so far. I was wondering, how are driverless buses within 4 _decades_ unlikely?

Of course they are unlikely, because the union will stop them.

Quiet Cooling With a Copper Foam Heatsink

Mirar Re:What are you running? (171 comments)

My heatsink losened from my laptop (MSI GT683R, i7-2630QM?), one of the nuts that was supposed to be soldered to the board stopped being soldered to the board. I couldn't figure out why it was throttling.

  It was throttling at 95C and hit temperatures up to 102C.

Gaming on it gave a full framerate for 10-15 seconds, then no frames for about 5 seconds, repeat. Still runs fine now after resoldering the nut to the board. And it never turned off, just throttled down to 200MHz or so and cooled down.

(If I remember correct my P4 happily ran at 85C too. But I might misremember. After that my stationaries have been watercooled and it's hard to get them over 55C.)

Quiet Cooling With a Copper Foam Heatsink

Mirar Re:I am skeptical (171 comments)

But with the foam you would use a lot less copper, at least. It'll be cheaper (if it has the same production cost). Not sure how to produce metal foam, though?

Foam has another drawback: Isn't it tricky to transport the heat all the way to the actual airflow, given the thin filaments and probably longer distances?

EU actually have comparably working IP laws. And we point and laugh at your problems.

That is, unless they get something like ACTA through EU parliament. Then we'll have it too.

Has the Ethanol Threat Manifested In the US?

Mirar ethanol has less energy per volume (432 comments)

It's not too strange to get worse mileage with ethanol, considering the energy content is less than gasoline.

Diesel has the highest energy content of the three.

Pure diesel or pure ethanol is easiest to optimize the engines for, since the fuel itself is rather pure, so theoretically you could get better mileage that way. Gasoline can vary a lot and is more of a mix of things.

Apple's Revenge: iMessage Might Eat Your Texts If You Switch To Android

Mirar not even XMPP (415 comments)

I have multiple devices, my friends have multiple devices.

There's no chat that works from multiple devices to multiple devices reliably. Which confuses me.

Traditional chats only works from one device to another device. There's no server sharing of information.

XMPP goes to only one device once that device has replied. That means that if the receiver is switching devices (goes from PC to phone to leave the house), messages might be lost and there's no history on the phone.

Message carbons tries to solve this - I think - but few clients support it, and even when it works, it doesn't solve the lock problem when leaving the house.

Google Talk is worse, instead of doing a handover to another device it steals the messages and sends you a Google Mail. Yay?

But this (the topic), I think, is one step worse.

Ask Slashdot: Minimum Programming Competence In Order To Get a Job?

Mirar levels? (466 comments)

What levels are we talking about?

If I could just pick any, I'd set someone who can write a tail-recursive strncpy in C on a whiteboard (and discuss the quirk) without any help at 2/10, and someone that can write/discuss a hardware UART driver or give me an idea of a posix-compatible SNMP SetRequest routine without any help at 8/10. Anyone who has implemented a HTTP server (without using a HTTP server library) in any language would score at least 5/10.

I think lots of programmers that score 2/10 can get work.

What are your 2/10 and 7/10? It's probably not my 2/10.

Or is there an official scale and my google-fu didn't find it?

It took me a while to realize you didn't mean a quarter of an hour.

Did the Ignition Key Just Die?

Mirar well, duh (865 comments)

I've been ready for that for years. I just didn't want to pay $$$ extra for that package (came with 'keyless entry' iirc).

I prioritized that my car can park itself and follow lanes using a camera (including that the car complains that i'm distracted/asleep).

Death Wish Meets GPS: iPhone Theft Victims Confronting Perps

Mirar Re:What police officers lack ... (664 comments)

Also, if the police would take it serious, and there were a risk of getting a SWAT team in your bedroom if you had a stolen iphone, I believe the attraction of owning a stolen iphone would somewhat be a little less.

Any crime the police stops caring about (stolen iphone, stolen bikes - I don't know where the limit is right now - pickpocketing, muggings?), that crime turns into not a crime. It'll be "ok" to do that. And there'll be a lot more of that crime, which means the police will not have the possibility to deal with it. It's a bad spiral.

If the police isn't protecting us, the police get meaningless and the laws get meaningless. It'd actually be better to change the law that iphone theft isn't a crime than to have it as a crime while the police refuse to do anything about it.

Mirar do your job (664 comments)

If they don't want civilians do to their job, they should do their job.

What's hard to understand about that?

Mind, It's also disproportionate to fetch iphones with SWAT teams.
These things do not always point to the correct address.
