  1. Re:code documents itself on How To Get Developers To Document Code · · Score: 3, Insightful

    Indeed, even if your code is complete clear on what it is doing, you should at least put in a comment on *why* it is doing what it is doing.

    Obviously, I used algorithm A, but why did I pick it over algorithm B. Is it because B isn't faster in this particular case or because A is less memory intensive, etc.

  2. Re:Non biodegradable? on Geek Tool: Slashdot Video of Award Winning 3D Printer From CES · · Score: 5, Informative

    PLA is corn based.

    PVA(polyvinyl alcohol) is made from polyvinyl acetate, which is made from ethylene, which is made from steam cracking petroleum. Not very renewable, but good as a wash-away support material.

  3. Re:A fairly general purpose board, not SPI, not pi on Raspberry Pi Gertboard In Action · · Score: 2

    As parallel ports become rarer(if not extinct already), I could see this becoming the best way to control CNC/3d printers once somebody ports a RTOS version of Linux to it.

  4. Re:Unsure about the gert... on Raspberry Pi Gertboard In Action · · Score: 1

    except with the Gertboard don't expect to be able to use any features in the chip that aren't put into the kernel by Eben and Gert.

    Except the Gertboard is just using GPIOs are presented as standard file interfaces. You can toggle them with any programming language, shellscript, or just typing 'echo 1 > /sys/class/gpio/gpio1/value' at the CLI.

    The GPU may be locked down and worthless for hacking, but the expansion pins are anything but.

  5. Food on Ebert: I'll Tell You Why Movie Revenue Is Dropping · · Score: 1

    I greatly hope more theaters like the Alamo Drafthouse or the Cinebarre open.

    Food, booze, and a lack of noisemakers makes me actually want to go to the theater.

  6. Re:Er, no. on IT Managers Are Aloof Says Psychologist and Your Co-Workers · · Score: 2

    Interesting. I went into IT after deciding I didn't want to get a masters to teach disinterested children when I could teach disinterested adults with just a bachelors.

    It took me a couple tries, but I've finally found a company where, with vigorous effort, I'm slowly driving spikes of knowledge into my coworkers' skulls.

    It is quite rewarding when the VP finally comes to you with a screenshot of an error message or an account manager realizes that "left click once" doesn't mean click repeatedly until something happens.

  7. Re:Jumpgliding? on Experimenting With Robotic Movement · · Score: 1

    I think somebody wanted to disprove that old saw about frogs not bumping their asses if only they had wings.

  8. Re:Vaporware until it is in my hands on Raspberry Pi Beta Boards Unveiled · · Score: 1

    I'll wait until it runs 3 months without the power supply melting. I've been burned before.

    *cough* Globalscale sucks.

  9. Re:Pretty late for this, don't you think? on US Bans Loud Commercials · · Score: 1

    Just slip a loudness clause into the advertising contract that states any ad not matching their sound profile will be adjusted to match.

  10. Re:Oh look, the pendulum. It swings back. on TSA Facing Death By a Thousand Cuts · · Score: 1

    You were probably thinking of silencers, which are allowed by the montana bill.

  11. Re:Really? on Swiss Gov't: Downloading Movies and Music Will Stay Legal · · Score: 1

    Just print up money on your computer.

    Because the government hates it you steal their gig.

  12. Re:like linux needs more fragmentation on Red Hat's Linux Changes Raise New Questions · · Score: 1

    blockquote fail

  13. Re:Why not Opt-In encryption or sharing the keys? on Police Encrypt Radios To Tune Out Public · · Score: 1

    Most of the encrypted radios in use have an opt-in/out feature. The problem with that is the users can't tell which is which or forget to switch.

    There was a study just a little while ago that sampled the failures of feds to properly use encryption: http://online.wsj.com/public/resources/documents/p25sec08102011.pdf

  14. Re:What is up with the name? on Ask Hacker and Security Gadfly Moxie Marlinspike · · Score: 2

    True names can be dangerous

  15. Anecdote!=data on Amazon Denies Reports That Airport Scanners Ruin Kindle's e-Ink · · Score: 5, Interesting

    That said, I've taken 3 different kindles(gen 2, gen 3, and the DX) through several airports in the US, plus taken the smaller ones through a few in Europe. Never had any problems after going through the xray.

    Well, no problems with the kindles, anyway. Once I got extra screening because the chargers "looked suspicious".

    IIRC, the 4th generation of kindles have exposed metal contacts on the back, so static from the rubber conveyor belt sounds much more probable.

  16. Re:Unlikely on Engineers Create World's Lightest Material · · Score: 4, Informative

    The trick is to purge the CO2 with helium or hydrogen after you've finished the supercritical drying.

  18. Re:Waste of Time on NYPD Dismantling Occupy Wall Street Encampment · · Score: 1

    Children can't vote.

  19. Re:No thanks on In-Vitro Muscle Cells, It's What's For Dinner · · Score: 1

    Industrial scale cell culture (think a number of very expensive pharmaceutical products) is incredibly complicated. You don't drop a bunch of stem cells into a vat and come back two weeks later.

    And despite that, we still produce alcohol on a local and industrial scale.

  21. Re:Root FTW on Ask Slashdot: Which Android Phone (and Carrier) For WiFi Proxy Support? · · Score: 1

    I could be wrong, but it looks more like he is talking about using WiFi connections to pull data instead of the cellular connection, which is what happens whenever I update my text-to-speech software(which downloads a 250 MB dataset).

    However, the browser doesn't do the same thing unless I explicitly disable the cell antenna(unless the settings are somewhere else).

  22. Re:Real scifi isn't about predicting the future on SF Authors Predict Computing's Future · · Score: 1

    3D printers are not set up to remove the finished parts and start the next one (at least not the home hobbyist ones).

    Makerbot has an automated build platform that ejects parts when they are done.

  23. Re:Existing original channels? on Original Content Coming To YouTube? · · Score: 1

    What, you mean like traditional TV is distracting everyone from watching My Drunk Kitchen?

    Funny, that doesn't seem to be happening.

  24. Re:Proof? on Pi Computed To 10 Trillion Digits · · Score: 1

    You can calculate any particular digit of pi(in base 16) without calculating all the preceding digits to verify they are correct.

    Pi = SUM(k=0 to infinity) 16^(-k) [ 4/(8k+1) - 2/(8k+4) - 1/(8k+5) - 1/(8k+6) ].

    Hopefully that won't get mangled.

  25. Re:Good Luck on 3D Printer For Your Kids · · Score: 1

    in the same realm as a makerbot: zentoolworks.com sells a CNC kit for either $800(7x7x2) or $1200(12x12x2) with everything except the computer.
