  1. Datarecovery "data". on Error-Proofing Data With Reed-Solomon Codes · · Score: 4, Insightful

    Working for a datarecovery company, I know that about half the cases where data is lost the whole drive "disappears". So, bad sectors? You can solve that problem with reed solomon! Fine! But that doesn't replace the need for backups to help you recover from: accidental removal, fire, theft and total disk failure (and probably a few other things I can't come up with right now)... .

  2. Technical reason... on PCMark Memory Benchmark Favors GenuineIntel · · Score: 1

    I would guess that when testing the same RAM with the different CPUs, different numbers would come out. So to even out the scores, they corrected by +47% for the slower Intel CPUs.

  3. Difficult design. on Virgin Galactic Shows the Finished WhiteKnight Two · · Score: 1

    The problem with this design is the mass that is on the other end of the "half-wing" in the middle. If you encounter turbulence while in flight, you'll be left with two half planes with only two engines on one side....

    My prediction: It will break. Maybe not on its first flight.

  4. Can they versus are they allowed to? on Reasonable Expectation of Privacy From Web Hosts? · · Score: 1

    I have two internet-servers. One is mine, and hosted at a provider. The other I pay rent, and they provide the hardware.

    Technically both ISPs have the ability to intercept enough internet traffic to snoop enough to be able to access my machines. Even if I don't give them a password to access my machine. But are they allowed to? I don't think so.

    You can rent physical space somewhere, and you're still protected by laws that punish the owner of the space if they violate your privacy. The same should hold for "a server" you rent somewhere. And similarly for a server you colocate at someone elses property.

    Now, when I see 1000 EMails sitting in my mail queue, I have to diagnose the problem. So after looking at the headers and seeing that all of them seem to be from my mailer daemon, what else can I do? I need to look at the contents of the mail to find out wether someone is deliberatly bouncing mail off my server to spam around, or wether they are normal bounces. So in the course of examening a problem, you might be forced to access private data. However this should be limited to "required use only".

    So when they are asked to look at a mail problem IMHO they physically can but are not allowed to access they MYSQL database.

  5. RHF stopped? on Robocars As the Best Way Geeks Can Save the Planet · · Score: 1

    Hey Brad, What happened to RHF? No new jokes for a couple of weeks now!

  6. HAHAHA! on Study Says Open Source Software a Security Risk · · Score: 1

    Have you voted yet? Apparently, about 80% of the readers of that article "doesn't get it", and votes the opposite of what the article is trying to push across....

  7. Simple. on How To Convince My Boss Not To Spam? · · Score: 1

    I for one will refuse to do businesses with companies that spam me. Spamming is wrong, and I will punish businesses that use the technique by not giving them my money.

    Just one "fake" address in the list will allow your competition to see that you've copied their list. You might get into trouble for that as well.

  8. Re:It is like magic. on HyperCard Comes Back From the Dead to the Web · · Score: 1

    GCC is the exception. Those stupid bastards writing GCC don't know what compatibility means. First they start adding warnings to perfectly fine code, then they change them to errors so that things no longer compile. Bah!

  9. Re:Vote Verification by Internet on How To Spot E-Vote Tampering? · · Score: 1

    This opens up vote buying: Someone says: I'll give you $10,- if you vote for me. Afterwards, you provide them with your random number, and you can prove you "earned" the $10. That's why someone suggested: "No cameras".

  10. Re:Heh, pirates ahoy! on The One-Use, Self-Destructing DVD Returns · · Score: 1

    Nah. I don't think so. They sell you the right to view this movie within a 48 hour period after opening of the packaging.

    They could just provide you with a regular DVD, and ask you to sign a contact that you will adhere to their rules, and throw the disk away 48 hours after opening of the packaging. In this case they have a technical solution to enforce this rule.

  11. My problem with music "the old way". on Advice On File Sharing For a Swedish MP? · · Score: 1

    I have a funny taste: I rarely like a whole album of an artist. Michael Jackson, Prince, Billy Joel, Genesis. Just one or two songs I like.

    So I'm willing to pay for the music I like, but I'd rather pay for just what I want to have and listen to, and not for the 90% of the songs on the album that I do not want. This has become possible in the digital age!

    With "old fashioned" production and distribution of CDs, a big percentage of what I pay go to production and distribution of the physical CD. Among others to the shop owner. In the digital age, this is no longer neccesary. So, I'd like to be able to buy songs, not for $1 a piece (which is the same price as $10 for an album with 10 songs) but for much less.

    The record companies should see, that even if they drop the prices, they can earn a lot more money. If you're selling a product that costs $9 to make, and you sell it for $20, and are considering dropping the salesprice by 50%, you're dropping 90% of your margin! So a 50% cost reduction for the consumer costs a factor of 10 in income for the company. However, if you're selling bits, the costs of reproduction of the product are minimal. So selling for $0.50 instead of $1.00, reduces costs for the consumer by 50% (causing an increase in demand), at a reduction in income (per song) for the company for almost the same 50%.

    How to change legislation to promote my ideal scenario, I don't know. :-(

  12. Not 256 next year, but 64 now! on Samsung 256GB SSD is World's Fastest · · Score: 1

    I don't want 256Gb next year. I want 64Gb right now for about a quarter of the price.... I can manage with 40Gb on my laptop. 2Gb of MP3's is enough, 2-5Gb of operating system, a few movies, which have to be "replenished" at home after viewing. All in all, you can make a laptop work just fine with 32 or 64Gb. The biggest laptop drives are now 160 or 200Gb. So why go larger? Just provide bigger sequential speed, better random access speed, bump-proofness. Bigger size next year is fine.

  13. tell / ask! on Getting Rid of Staff With High Access? · · Score: 1

    I read the first 50% of the comments, but didn't see what I'd do. (and I have to get up really early tomorrow)

    Just tell them what your intentions were, and what they are forcing to do (i.e. nothing). Then ask them what they want. Volunteer to be paid to sit at home. Offer to have the cell phone handy for questions.

  14. Linux kernel. on Do Static Source Code Analysis Tools Really Work? · · Score: 1

    Some people ran these kinds of tools on the Linux kernel, and found some suspicious code. It is similar to turning on -Wall on your gcc compiler: Some bugs suddenly turn up (with exact line number!) without having to go into the testing phase. This means you have more time to test for real bugs that only show during runtime.

  15. Re:Another entry into the market is always welcome on Robotic Camera Extension Takes Gigapixel Photos · · Score: 1

    How much did it cost to make that print? Where did you have that done?

  16. Availability of PCMCIA WIFI cards. on What to Seek in an Older Subnotebook? · · Score: 1

    FYI, I've been looking for a 16 bit PCMCIA WFI card for my aging laptop, and haven't found one. I now use an USB one... (Of course they used to be available "back then", but I couldn't find a reasonably priced one now....)

  17. Links in article... on Dutch Voting Machines De-Certified · · Score: 2, Informative

    Please mention the "real" URL: http://www.minbzk.nl/actueel/112441/nieuw and provide the link for the translation behind in parentheses. Even though Dutch is a language spoken by a relatively small number of world citizens, there are some who prefer the Dutch language.

    I myself prefer to read English unless Dutch is the original language.

  18. Current price? on $1/Gallon "Green Gasoline" In Sight · · Score: 1

    What's the current price of Gasoline (in dollars per gallon) in the US (or canada)?

  19. It matters a lot. on For CS Majors, How Important Is the "Where?" · · Score: 1

    As a Dutch guy, with slightly more math in the Dutch high school than an average American high school, I went to a (selective) American liberal arts college.

    In my first year, i took a few Math and CS courses that I liked. I then realized that to graduate in Math or CS, I would have to start taking the courses that were prerequisites to the ones I took, because otherwise I would not be able to gather enough Math courses to qualify as a Math major. Same for CS.

    IMHO, learning to program is important. Learning programming languages is not.

  20. Harddrive... on Best Laptop for Going Around the World? · · Score: 1

    As noted above, needs stating again...

    Harddisks are specified to work upto 10000 feet or 3000m. Above that, you're on thin ice. Solid state drives are becoming available. Sounds like a good plan to go with one of those.

  21. Local networks going away? on LAN Turns 30, May Not See 40? · · Score: 0

    My prediction is: Not in a 100 years.

    People above mention security as a reason.

    That might be one reason.

    However, for professional use, the current wireless speeds are really too slow. There will always remain applications that are content with wired speeds, and not with wireless speeds.

    There is a technical reason that wireless is harder to get high speeds on: If you do wireless, 99% of the transmitted energy goes places where it is of no use to the receiver. On a longish cat5 cable, you might lose 50%, but the other 50% actually makes it to the receiver!

    The current situation is that 54Mbit wireless is dirt cheap. And way above the WAN connection that most homes have. That won't change, so most home users will, upon the next upgrade, switch to wireless.

  22. Re:Datarecovery of SSD drives. on Data Recovery & Solid State · · Score: 1

    We charge by result. This means: No cure no pay.

    Secondly, you don't care about wether or not we just had to run our in-house data-recovery software, or we had to swap platters with a different drive.

    On a job where we have to figure out how things work, we usually lose money (or "invest"), but we learn things which we will write off on future jobs.

  23. Units, physics. on World's Most Powerful Rail Gun Delivered to US Navy · · Score: 1

    Will someone please get their units straight? The small capacitors next to my CPU easily do three million amps per second, so what's difficult about 3 million amps per shot?

    My CPU goes from say 10A to 100A in a few nanoseconds when it wakes up from sleep. This is 90 amps per "few" nanoseconds, or on the order of 10 billion amps per second (I canceled out 9 versus "a few"). That's 3000 times more than 3 million amps per second.

    32 megajoule is not that much either. A typical airliner engine delivers that amount of energy every second. They mount a couple of those on a battleship for "emergency power" anyway.

    So, with such a gun, you can shoot 2 or three rounds per second when powered by a gas turbine. Problem is that the army guys are probably aiming for more like 10 times that.

  24. Datarecovery of SSD drives. on Data Recovery & Solid State · · Score: 5, Interesting

    I work for www.harddisk-recovery.com .

    We will gladly reverse engineer the data-distribution algorithms that the SSD device uses on a case-by-case basis. We have done so in the past for several different USB sticks. We will desolder and read the individual data-holding chips and then reverse engineer their scrambling algorithms. We will then recover your data from whatever chips still work sufficiently to provide us with some data.

    The first time this will take us a few days extra. Expect about a week turnaround time the first time anyone sends us a failed SSD disk.....
