Apple Patents Alternative To NFC

victim Re:Ammo for the lawyers (171 comments)

How on earth does a May 2011 hackaday come a year and a half before an October 2009 patent filing?

Patents: All of the words in the laws are important.

The Oatmeal's Fundraiser Tops $1M Toward Tesla Museum

victim Re:Another Tesla museum? (63 comments)

since most people are not going to happen to go to Belgrade.

Which is good, because if most people were in Belgrade that would be slightly more than 10 people per square meter.

WD Launches 3 Terabyte HD

victim Re:Do they self destruct like other Greens? (313 comments)

And as soon as everyone is omniscient about the undocumented behavior of their devices and the "documented only in source code" behavior of all code of their systems this will be a brilliant solution.

WD Launches 3 Terabyte HD

victim Re:Do they self destruct like other Greens? (313 comments)

I will respond to your dickish tone with my own:

Ever here of a log file?

How about if you are monitoring the S.M.A.R.T. data to watch for signs of drive failure? You will destroy the drive instead. (Especially if using Munin, because it doesn't show Load_Cycle_Count by default so you won't see it take off.)

How about when your OS is clever and tries to reduce disk use by only flushing the OS block cache intermittently, and that interval is slightly greater than the park timer? Your machine under continuous use parks and unparks continuously.

So there is this little computer in the drive making park decisions. Shouldn't it notice that the drive is parking too often? WD knows how many parks it built the drive to survive, it knows how frequently it is parking. Cap the park rate! Problem solved.

WD Launches 3 Terabyte HD

victim Re:Do they self destruct like other Greens? (313 comments)

So? What is your Load_Cycle_Count? That is what is being discussed here. The drives are rated for 300,000. I have ones near a million that haven't failed yet, but have also failures around 600,000.

iPad Review

victim Location does work (750 comments)

My iPad has correctly found me in all four locations I've tried by triangulating WIFI access points.

Apparently mobile users with GPS have tagged my access points.

Coping With 1 Million SSH Authentication Failures?

victim So? (497 comments)

If you really have secure passwords, the random guessers aren't going to get them. Log it and move on.

I get thousands of Chinese hackers attempting to break into the battery monitor in my tool shed, big deal. I don't know why my battery voltage and solar current is so important to them, but they can knock themselves out all day.

If the logs bother you then install fail2ban and configure it to lock people out after a few bad guesses. (Then be ready to unlock yourself from an alternate IP when you inevitably lock yourself out.)

Suggestions For a Coax-To-Ethernet Solution?

victim Re:Use the Coax to pull CAT 5e cable (608 comments)

Ethernet coax was 50ohm, the stuff in your walls is probably 75ohm. They are not interchangeable.

Might I suggest you join us in the 21st century and just use 802.11n? USB dongles can be had for about the cost of a cat5 patch cable and 802.11n is as fast as 100mbps ethernet.

Plus you gain some nice lightning damage protection by eliminating the second electrical path.

"Green" Ice Resurfacing Machines Fail In Vancouver

victim Re:Green ? (356 comments)

In general large power plants are more efficient than small point of use engines, this is traded off against transmission losses and can end up either a win or a loss for total input energy.

For cleanliness, power plants run much cleaner than small point of use engines and they don't concentrate the adverse effects in close proximity with people. (You may need to pee, but don't do it in the pool.)

Low-Power Home Linux Server?

victim Re:Atom 330 Desktop/Server - second this (697 comments)

I use a few of these in different place. It won't get you to the 10 watt range of the reflashed routers, but you save much time in wrestling fringe distributions in to working the way you want them to. (I have wrtsl54gs boxes running OpenWRT too, Atoms are more convenient.)

Do replace the motherboard fan if you get the intel motherboard. It will probably fail soon and cause your CPU to start thermal throttling. I just took it off and placed a full sized fan on the case vents over the motherboard blowing down. It runs cooler, quieter, and longer.

NCSU's Fingernail-Size Chip Can Hold 1TB

victim There is no chip. (227 comments)

They have made a material which could if you designed a suitable chip and associated circuitry, and figured out how to manufacture it at large scale, would let you store a terabyte of data on a fingernail sized chip.

The whoever wrote the article title should be embarrassed, as should timothy for propagating it.

Replacements For Adobe Creative Suite 3 Apps?

victim Re:I don't get it (270 comments)

I should add, my copy of Illustrator for Mac is 5 years old and works like a champ. So, depending what you do with CS you may not even care.

Replacements For Adobe Creative Suite 3 Apps?

victim Re:I don't get it (270 comments)

No, but Adobe is. They have a long history of doing stupid things, then waiting until the actual consumer release to "discover" that their product has a problem and not fixing it until the next major release thereby preventing their users from upgrading OS.

In this case CS3 may actually work, they just aren't going to promise it so people will pay to upgrade and Adobe doesn't have to do any support on CS3.

Intel Cache Poisoning Is Dangerously Easy On Linux

victim Re:First you need root on the box (393 comments)

The significance of SMM buried rootkits is that you can remove and shred the hard drive of your compromised machine, replace it with a new one, do a fresh install, and still be compromised.

Ext4 Data Losses Explained, Worked Around

victim Workaround is disaster for laptops (421 comments)

The workaround (flushing everything to disk before the rename) is a disaster for laptops or anything else which might wish to spin down a disk drive.

The write-replace idiom is used when a program is updating a file and can tolerate the update being lost in a crash, but wants either the old or the new to be intact and uncorrupted. The proposed sync solution accomplishes this, but at the cost of spinning up the drive and writing the blocks at each write-replace. How often does your browser update a file while you surf? Every cache entry? Every history entry? What about your music player? Desktop manager? All of these will be spin up your disk drive.

Hiding behind POSIX is not the solution. There needs to be a solution that supports write-replace without spinning up the disk drive.

The ext4 people have kindly illuminated the problem. Now it is time to define a solution. Maybe it will be some sort of barrier logic, maybe a new kind of sync syscall. But it needs to be done.

Obama Transition Team Examining Space Solar Power

victim Re:Who do you trust with a death ray? (275 comments)

Your numbers are likely off by several orders of magnitude. 100W/m2 is 1/10th the energy density of direct sunlight. i.e. you can do ten times better than that with a flat mirror, no concentration.

Who says it has to a be a centimeter wavelength? How about the 95GHz pain beam? (I haven't checked to see what the atmosphere does at that wavelength, I would suspect clouds block it at the very least, but given that light is shorter wavelength and it penetrates well, I'm fairly certain there will be something between cm and nm that also works well.)

Of course in normal operation your 1000 units would beam to 1000 different reception sites at a safe level, it is only when you want to destroy someone that you divert them all to your enemy.
