Snowflake-Shaped Networks Are Easiest To Mend

Mirar hm? (38 comments)

Is this an attempt from mathematicians to try to tell engineers they have been doing it wrong?

This seems to be a very easy conclusion if you don't have to think of all the other things you need to think of when you do things in the real world.

And I can't see any problems solved with the conclusion of this paper.

Boeing Told To Replace Cockpit Screens Affected By Wi-Fi

Mirar so they missed a certification? (142 comments)

I'm guessing they blasted the screens with several kW in the spectrum that is around radar and wi-fi, and they blanked out?

It's probably a problem being directly in front of a radar transmitter, but wifi is just in the right spectrum, much much weaker...

Piracy Police Chief Calls For State Interference To Stop Internet "Anarchy"

Mirar fix the laws (302 comments)

If you fixed the laws instead, so it would be a different level for crimes on the internet, there wouldn't be many people breaking the law. Make it legal to download and share intellectual property between individuals. No problem, no lawbreakers that you need to check up on.

It's like introducing a law that you can't go out between 12:00 and 12:01 every day and then say that you need to tighten down the streets with gates and armed guards, and have automatic locks on all doors that doesn't open outwards starting at 11:30, to protect people from breaking the laws.

Sadly, England might not be far from introducing license-only websites. (Scotland, why didn't you run while there were time?)

Drones Reveal Widespread Tax Evasion In Argentina

Mirar why drones? (208 comments)

So they couldn't do this from satellite fotos from Google or Bing? Or just normal, you know, the photos taken anyway from flights for planning?
What is the benefit of drones, better pictures of the topless people at the pools? (Pay your taxes, or our drone photos will hit the internet!)

Remote Exploit Vulnerability Found In Bash

Mirar Re:Worse than you think. (399 comments)

How do android/ios run DHCP?

How do cheap all-in-one ADSL modems run DHCP?

I think that will tell us how bad this is. That's where the worms will live.

Small Restaurant Out-Maneuvers Yelp In Reviews War

Mirar Re:The review ecosystem is good and truly broken.. (249 comments)

Are you sure the /. system have a good reputation system? It seems to me it's really hard to come in as a new user and get good enough reputation to actually be listened to these days. Stack Overflow seems to have these problems too. Early adopter with good reputation, on the other hand, will not have any problems.

Small Restaurant Out-Maneuvers Yelp In Reviews War

Mirar ...as well as tripadvisor (249 comments)

Two restaurants I visited in Berlin did not have a Tripadvisor post. When I asked about this, they asked to please not add them to Tripadvisor because of extortion.

This is why we can't have nice things.

Navy Guilty of Illegally Broad Online Searches: Child Porn Conviction Overturned

Mirar gnutella... (286 comments)

...I didn't know you could hand-pick the computers you searched on gnutella. Isn't it a p2p search-tree (or a broadcast) that you can't limit to any geographic area or ip range other than filtering the end-results?

The State of ZFS On Linux

Mirar well.. (370 comments)

I tried to run backups to ZFS on a crypted USB disk. It worked for a while, but if something fails (like the backup disk going to sleep), the entire chain hangs. I can't disconnect the crypt device, and I can't disconnect the ZFS pool, zpool and zfs hangs. What I do with the USB cable and hardware no longer has any impact. I stopped doing that. (I didn't have better luck with btrfs.) Although I don't really blame ZFS that much other than it can't handle hanged devices. USB on Linux is still flaky.

The other problem I have is that it after a while happily uses up 30GB of my 32GB on the computer, and extremely reluctantly gives them away again. I can't seem to be able to control how much ZFS will use. And the rest of the system isn't really happy with just 2GB to run programs in (several virtual machines of 8GB RAM each, for instance).

The State of ZFS On Linux

Mirar Re:Unfamiliar (370 comments)

The big difference from raid+filesystem to zfs or brtfs is that the new ones have a checksum on the raid blocks.
That means that if you get bit errors (or more than bit errors) on one of the blocks on the raid, you can rebuild that block from the others.

WIth a normal RAID there is no way of telling which bit is wrong, just that the blocks don't match up anymore. You're protected against one disk failing, but not the random errors.

You can also add deduplication, compression and snapshots if you want. Don't know how LVM+raid works with that.

New EU Rules Will Limit Vacuum Cleaners To 1600W

Mirar so 1h every 10 day per citizen (338 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?
