  1. Privacy in the USA? on Senators Call On FCC To Investigate Carriers Selling Location Data To Bounty Hunters (vice.com) · · Score: 1, Funny

    Must be a bugger to live in a country where privacy protection is the exception to the rule.

  2. Re:I'll tell you what's unsafe. on Vaccines May Soon Be Mandatory For Children In France (theverge.com) · · Score: 1

    The lifesaving effectiveness of vaccines may actually be exceeded by that of safe potable water and sewerage systems.

  3. Would be great if applied to toilet bowls, etc. on Scientists Discover a Way To Get Every Last Drop of Ketchup Out of the Bottle (bbc.com) · · Score: 2

    Can it be applied to ceramic surfaces?

  4. Re:Lots of people don't want the "smart"-phone on Slashdot Asks: Is the App Boom Over? · · Score: 1

    You can order a dumb phone from the far East and have it delivered to your home for $12.50. Quad band, no SIM lock. Don't believe me? check out http://www.buyincoins.com/item... .

  5. Hypervisor leaks cached data on Attack Steals Crypto Key From Co-Located Virtual Machines · · Score: 0

    It appears that the hypervisor leaks data from one VM to another by not clearing a cache. If that is all, this leak can be fixed by explicitly clearing the cache when switching to another VM. This will probably cost a few CPU cycles (and cause a few extra cache misses when a VM is resumed).

  6. Electric pencil sharpener on Creative Uses For Extra Drive Bays? · · Score: 1

    I'm still waiting for ThinkGeek (or a similar outfit) to start selling an electric pencil sharpener that fits in a standard drive slot of my PC and is powered from the PSU of the PC. Keeping the wood and graphite particles away from the innards of the computer may pose a problem.

  7. Re:A step in the right direction. on Judge Strikes Down COPA, 1998 Online Porn Law · · Score: 1

    Because the man that uses porn is more likely to look at women like objects or a piece of meat instead of as people or equals as they deserve. Not every man does it, but its a pretty significant percentage of men that indulge in a pornography habit.

    Don't confuse correlation with causation.

  8. Why display these adds at all? on Unwanted Popups Boosting Web Traffic · · Score: 5, Insightful

    Wouldn't it be much smarter if these adware companies let their malware fetch the popup file (pretending to be any popular web browser) and not display it to the user? Most users would never notice the additional network traffic and, not having seen a sudden popup, would have little incentive to go hunting for the spyware.

  9. Not very expensive... on Japan's New Supercomputing Toy · · Score: 1

    That lease price is probably per year and a year is approximately 31556909 seconds.
    Assuming a US trillion (1E12), gives 59E12 operations per second, or about 1.86E21 operations per year. That is about 62E12 operations per dollar. There will probably be some (rather significant) additional costs to run and cool the beast...

  10. Re:Spam, SpamAssassin, DigiCash on PayPal to Offer Micropayments · · Score: 1

    Using an digicash-like micropayment should be simple to implement. The SpamAssassin program would "deposit" the digicash that came in the mail header into the recipient's account and reduce the spamminess score of the message (if the bank flags it as "counterfeit" the spamminess score would increase) . You might need some method to prevent "theft" of the digicash by mail relays...

    Sounds like a great use for digicash to me.

  11. I'd rather lose the motorman than the conductor on New York Computerizes its Subway System · · Score: 2, Insightful
    When the entire line runs on dedicated tracks where the probability of people, cattle, or trees obstructing the tracks is negligable, using a computer to drive the train makes sense. I wouldn't want to do without a conductor though.

    The London Docklands Light Railway is an example of such a system. In case the automatic system breaks down (which happened very often when LDLR was new) the conductor has the keys and skills needed to drive the train manually. Usually (s)he drives the train to the next station and restarts computer operated mode. The conductor's primary function is to close the doors and ensure safety on board of the trains and to assist passengers with boarding, alighting and information.

    In automatic mode, the computer stops the train at each station and unlocks the doors. When the time to depart has arrived the RTD (Ready To Depart?) light comes on (there is one at every door). The conductor is then supposed to close the doors (using a key that can be used in a lock present on any of the doors). When all doors are closed the ADC (All Doors Closed?) light (also at every door) comes on and the train departs.

    As there is no train driver cabin, the passengers have a nice view in all directions (LDLR runs mostly on elevated track). Having no driver cabin saves some space too. (The manual driving controls are behind a cover.)

  12. Re:Got them, can't view them on A Crazy Cambridge Contraption · · Score: 2, Interesting

    Winamp5 does fine (on my XP machine at least).

  13. Re:Economical - Slowing Fans on Building a Silent, Air-Cooled System · · Score: 1
    I converted my fans to run on 7 volts. All you have to do is switch the order of the wires around on the molex power connector. It's really easy:

    Until, of course, one of your fan motors shorts out and connects 12 Volts to circuitry that is supposed to run on 5 Volts. Folks, that kind of damage is not covered by your warranty...

  14. This photo is NOT taken from TNO property on Largest Digital Photograph in the World · · Score: 1

    I know the location where this photo was taken very well. It is from way up in (or on top of) the electrical engineering building (now EWI) of the Delft University of Technology. The church tower in the center of the image is the nieuwe kerk (New Church). This is NNW from the standpoint of the photographer.

  15. 60 Make networked home PCs back each other up on 101 Ways To Save The Internet · · Score: 2, Interesting
    Now that would be a great thing, provided that the backup (and all network traffic) is encrypted. Naturally, we would all have to buy 100% more disk space than we actually use for our own data. I would be glad to buy the additional disk space (to hold other people's backups) provided that someone else buys disk space that will contain a backup of my stuff. I suppose that such a system should really have with a bit more redundancy (like RAID5), so participants in this system would have to buy slightly more than 200% disk space...

    Even with an intelligent way to keep the encrypted mirror of my disk(s) up to date I would need to have a bit more bandwidth into my home than I do now, but that will be taken care of in the near future.
    Is there a Freshmeat project like this?

  16. Our university is blocking infected systems on Code Redux · · Score: 1

    The network managers at the Delft University of Technology are monitoring the scans by the infected systems. If they can not contact the maintainer of these systems they will configure the ethernet switches to isolate them from the network.

  17. K'nex is comparable to Meccano on Lego Vs. Meccano & Engineering Knowledge · · Score: 2
    Unlike Lego, building serious constructions with K'nex does require good constructive insight. After a while you get to know what makes a strong construction and what doesn't. I suppose that Lego Technic (sp) is fine too (I never had any Lego Technic parts). Fisher Technic is also very Meccano-like.

    The main advantage of K'nex over Meccano is that it does not require all that dexterity to put those tiny bolts and nuts together. A secondary advantage of K'nex over all those others is price. You can buy an awful lot of K'nex for two hundred bucks.

    Personally, I don't like the K'nex robot building stuff very much. There is no way to write your own software. Lego Mindstorm stuff is probably much better than the K'nex attempts at intelligent components.

  18. Re:Technically plausible - NO WAY on Massive Bandwidth over Powergrids? · · Score: 1

    There is no technology on this world that can transmit exobits per second. (Should probably be exAbits.)
    Gigabits: no problem (but a big problem when transmitting over powerlines), Terabits: not yet (maybe someday during my lifetime). Exabits: probably not during my lifetime.

  19. Re:Ericsson's "e-box" appliance is based on Linux on AOL Making a Linux Box? · · Score: 1

    Is the e-box really Linux-based ?

    I can't find the word Linux on Ericsson's web site
    about this product, nor in the PDF file that gives
    more details about the e-box.
