  1. Re:Theft? on Grad Student Project Uses Wikis To Stash Data, Miffs Admins · · Score: 5, Insightful

    My response: cry me a river, and congrats to the grad students for their innovative work in the field of distributed communications.

    I'd pause before calling this innovative. It doesn't really take much to encrypt data, chop it up and stash it on MediaWiki sites -- either in theory or in practice. If you want something "innovative" in the same vein, I'd vote for the guy who wrote the device driver that lets you use GMail as a drive (spawning many copies). Sure it isn't "distributed", but you could set up multiple GMail accounts to handle the contents of your drive. Clogging up other people's wikis is d**k at worst (and possibly a violation of the CFAA), and really not too much of a security threat at best ("oh? my disk is full? hmm...just dump this spammy user account, or restore the last backup, and password protect the whole business.").

    What these grad students have done is demonstrate that open mediawiki setups can be spammed. Whee.

Mr. Bradley holds him up as example of what a difference one determined man can make in his community.

    From the company's point of view, if you're having a "bad decade", you're probably not of much use to them. As dehumanizing and cynical as it sounds, companies exist to make a profit, and if you're not serving that function or are not somehow contractually bound to them, then you don't have a place there. Don't jump on a sound bite and delegate the whole process to "fucking stupid". They're not just blindly looking at email patterns.

    Exactly. Our lab submitted a collaborative paper that involved five people editing the document. SVN was more than enough for our needs, and all you need is an Apache install running somewhere. It literally was painless because of SVN, just make sure everyone types in descriptive log messages. Bonus: the commit logs can help you determine the order of authors :)

    On the frontend, the best SVN clients I've used are TortoiseSVN for Windows and RapidSVN for Linux. As I said, couldn't be happier with the setup. IMO, any more functionality is absolutely unnecessary.

    What exactly does Godel's theorem have to do with what you just said? The incompleteness theorem deals with axiomatized systems.

    Was that Yamaha pickup any good? I remember seeing it in a music store some years ago and wondering if it actually worked. It seems like a relatively trivial problem to solve if you can attach a pickup, as they did. Transforming the audio into some kind of useful MIDI information in realtime seems horribly difficult but also doable... just not without immense processing power.

    I tried it in a music store and it seemed to be capturing basic pitch and velocity pretty well for each string, which is pretty neat. I don't imagine that it would take too much computational power, since the underlying computation is basically just doing an FFT on the audio signal and picking up the fundamental frequency. That translates quite well into a MIDI note on/note off command. FFTs can be done really efficiently in hardware I believe.

    Wasn't this idea thrown around when the MIDI interface was created, 20+ years ago?

    But of course...we're now coming full circle when people realize that they can do this Guitar Hero stuff on real guitars, and without the buttons either. Turns out, guitars actually make music all by themselves (with possibly just an amp)!!! But I digress--for those interested in music, here are the relevant things that precede this in time and in awesomeness:

    Yamaha MIDI pickup for guitars -- turns the note you're playing into a MIDI note that can then control a synth on your computer. And I don't mean the 80's era crappy "synth" sounds, modern sound synthesis engines are INCREDIBLY realistic.

    Alternatively, you could skip Guitar Hero completely and do the following:

    1. buy yourself a real guitar
    2. Get Guitar Pro 5 with it's "Realistic Sound Engine" or use TuxGuitar on Linux.
    3. Download a Guitar Pro file of your favorite song / use TuxGuitar to import a MIDI file -- the modern software synthesizer sounds nothing like what you might remember from the 80s. Bass and drums are very realistic.
    4. Mute the guitar track in Guitar Pro/TuxGuitar, and play along with full drum/bass accompaniment. The software even scrolls as you play along.
    5. If you like eye candy, route your sound card's output into Winamp and run a visualization.

    This is the method I use and it's incredibly satisfying if you don't happen to have a band lying around. Plus it also lets you choose which part you want to play along with, speed up/slow down the song. Sure there aren't any vocals, but it's still mucho fun and way better for impressing people with.

    Given classic random theory, given a series of 50/50 type decisions, out of 32 people, one person will be completely screwed and one person will win every time. For larger data sets, the lucky runs are only longer.

    This is absolutely meaningless, a hodgepodge of statistical fallacies and vagueness. Given a "series of 50/50 type decisions", assuming each decision is independent, then it is absolutely not necessary that "in larger data sets, the lucky runs are only longer". If each decision is a coin flip, then there is no "memory" of prior decisions, so the probability of getting a long "lucky run" is exactly the same regardless of the size of the data set. The length of a "lucky run" is independent of the size of the data set.

    In the context of Gladwell, you could say that "genius" is the independent co-incidence of (1) having innate ability and cultural preparation and (2) the right circumstances presenting themselves. One or both of those events have very low probability, so when they coincide and create a Bill Gates, we get an "outlier" relative to the life experience of the vast majority of people.

    It's not science, it's just probability. It's senseless to try to assess any statistical estimates *themselves* based on Physics, just the probability that they could be wrong based on some very broad assumptions. Specifically, any estimate is arrived at by a chain (rather, DAG) of logic. What you CAN estimate is the probability that any Physics-oriented estimate is based on incorrect assumptions, by (presumably) analyzing that chain of reasoning down to first principles and assuming that a "logic error" might have been made at any point. I hope that the authors aren't taking it further than this, in which case, this is statistical masturbation.

    This is incorrect. WEP has a well-known attack that uses statistical properties of captured packets to limit the search space of the brute-force search. With enough captured packets, it takes under a few minutes to crack a WEP key. WPA does not have this vulnerability, although some variants of WPA are still less secure than other. In other words, all you have to do to crack WEP encryption is put most cheap $20 wireless cards into "monitor" mode, capture WEP encrypted packets and with enough packets, crack the key in under a few minutes. Again, WPA is not perfect, but does not have such an easy statistical attack either.

    All it takes is for you to watch one long YouTube video or transfer a relatively large attachment to capture enough WEP packets. I had included a link with the original story that was removed by Soulskill, here. You don't even have to be "hacker smart" to crack WEP, just know enough to read a few articles, run linux and download a few pieces of software.

    What's worse is that where I live, AT&T ships 2WIRE routers that only have WEP encryption with 40bit keys and no MAC filters. This almost guarantees that AT&T DSL can be easily cracked by someone with a laptop and the (freely downloadable) aircrack suite. That's something to think about the next time you're downloading a torrent... So, monitor your routers access log, set up a MAC filter, use better encryption if possible, or at least longer WEP keys -- nothing's perfect, but it each puts up one more obstacle.
