  1. Three Words on Math And The Computer Science Major · · Score: 2, Interesting
    Big O Notation

    Just to know what makes a good program involves quite a bit of math. Nothing made the speed of nested loops clearer to me than this. Basically, it lets us define the best worst and median cases of general types of code with very simplistic functions.

    O(1) - loopless program
    O(N) - One loop from 0 to N
    O(N^2) - One loop from 0 to N with another loop nested in it that is from 0 to N

    So, the length and basically anything that is only executed once is considered inconsequential. It also shed light on
    "I can just do this with two nested loops, why would I possibly have to write this with a/an <advanced data structure>?"
    is a stupid question.

    Coincidentally (no it's not a coincidence), the number of CS sutdents that change their majors to something else during the first year is about 40%.
  2. Obligatory PA reference on Sam Lake on Video Game Storytelling · · Score: 1

    Not that I am one to disagree, because I've never played the sequel, but MP2 has long been a butt of joke after joke because of the dialouge. All this despite the fact that everyone agrees that the game itself is very good. But it sounds as though you are talking about the story more than the game, and thusly the dialouge more than the play.

    Avalon is the new Windows API, and it apparently represents a major jump in UI capabilities. Part of its value proposition is in the ease of use to developers and part in the experience for end users.

    In order to increase developer productivity, Avalon will rationalize and reduce the number of APIs in the Win32 stack from over 70,000 down to 8,000.

    On the user experience side, Avalon will feature advanced support for 2D and 3D vector graphics as well as standard GUI widgets.Some descriptions of Avalon suggest that it is more comprehensive than just the graphics layer, and will incorporate support for paradigm-shifting "task-oriented" UIs.

  8. Re:I'm obviously not understanding something here. on After DeCSS, DVD Jon Releases DeDRMS · · Score: 1

    >I don't see the point you're trying to make. DVDs may not explicitly state that you have to do X or Y, but with CSS encryption combined with the DMCA, they might as well.

    The point would be the difference between these two situatuins:
    When you buy a DVD you do need specific hardware that is not mentioned and that you never agreed to needing, that the DVD actually implies (if not purports) to not need. This is a Bad Thing.

    When you buy a iTMS song (you buy nothing, you license it), you agree to certain restictions about how you can use the song you have LICENSED. So, them providing you with a format which you can only use in the way that was specified in the license is perfectly within their rights.

  11. Re:Other platforms on WormRadar Node Volunteers Help Graph Attacks · · Score: 5, Insightful

    From The Jargon File

    honey pot: n.
    1. A box designed to attract crackers so that they can be observed in action. It is usually well isolated from the rest of the network, but has extensive logging (usually network layer, on a different machine). Different from an iron box in that its purpose is to attract, not merely observe. Sometimes, it is also a defensive network security tactic -- you set up an easy-to-crack box so that your real servers don't get messed with. The concept was presented in Cheswick & Bellovin's book Firewalls and Internet Security.
    2. A mail server that acts as an open relay when a single message is attempted to send through it, but discards or diverts for examination messages that are detected to be part of a spam run.

    With emphasis on the attract part. How are you going to monitor worms that propigate using windows with a linux box? You may be able to say, for instance, how many times a certain port was probed. You can't get a linux box to respond in the same way as a windows box without seriously getting into the kernel though.

  12. Re:It sounds like hitting water at high speed on Military Develops Liquid Body Armor · · Score: 1


    It sounds like it works on the same principle that making a dive into your swimming pool is different from jumping off the Golden Gate Bridge into the Pacific. Nifty stuff, although it seems that its resistance to stabbing has to be called into question when you consider that it's also sewable.


    If the material is really linked to speed of impact, then wouldn't that just mean that it would have to be sewed slowly?

    You ought to read dune, that's how their armor worked (sans the force field part), it was speed related.

    That shouldn't surprise you, after all water(H2O) is that major component of your body, but Hydrogen Peroxide(H2O2) would kill you, and all it has in one more oxygen.

    So one one hand we have the basis of all life and argurably the most harmless liquid on the planet, and on the other, a rocket propellant.

    Don't anyone respond with that crackpot shite about hyper-oxygenation therapy. I'm talking about concentrated stuff. Here's what wiki has to say about it.

    "35 percent Food Grade Hydrogen Peroxide", which is 35% pure hydrogen peroxide, has been marketed under names such as "Oxywater" or "H2O2", with claims of medicinal or therapeutic value. According to peddlers of the product, it can be diluted and used for "hyper-oxygenation therapy" to cure AIDS, cancer, and many other conditions. Some have claimed that information about these "beneficial" uses of peroxide have been suppressed by the scientific community. The US Food and Drug administration has published a warning against the use of 35% peroxide in the home for any purpose. At least one death, and several serious injuries, have occurred as a result of ingesting this treatment. People who use 35% hydrogen peroxide "water it down" to whatever concentration is needed for the specific situation. Storing 35% makes it convenient to keep enough on hand, which is why people buy it this way. For example, use of 1 cup of 35% H2O2 in a warm bath is simple (and cheap), where use of 3% H2O2 would be less convenient (about 11 cups) and more expensive.

Before I had money again I vowed that I would no longer support the RIAA by purchasing a CD that came through a major record producer.

    You mean from "the fastest way to get around was with a horse" to "we sent someone up to stand on the moon''. You really think that you will do better than that?
    These are estimates, don't get all anal.
    Horse: about 20 m/s
    Escape velocity of the earth: 11,000
    So we have a multiplyer of about 550. Are you then making the claim that we will have travel that will not only be faster ut be signifigantly(put to shame) faster than 6,050,000 meters per second? That would be about 2147483.647 MPH or the speed of young supernova ejecta and (someone help me out here) 59 330 232.5 gravities.

  22. Re:Hydrogen Powered Cars on How Will We Get Around Near-Future Earth? · · Score: 1

    Another way to think about it is:

    * We will eventually run out of oil and its byproducts. This will nessecitate the obsolesence of the internal combustion engine based on a petroleum product.

    * We will need to find a renewable energy alternative but we don't know what it is now. Could be solar, could be biomass, could be small(safe) nuclear reactors.

    * Hydrogen fuel cells/electric cars will work with any type of energy production.

    We will be able to smooth the transition by using H2 cars now al letting them proliferate while we still do have oil. Then when it is all gone, we won't have some sort of transportation crisis, we will just power up out fuel cells using a different source and most people will never know the difference.

  23. Re:End of Oil? on How Will We Get Around Near-Future Earth? · · Score: 1

    The advantage that we glean from moving away from the internal combustion engine is in the amount of energy that is extracted from the fossil fuels that we burn. These are from memory so don't get all anal about them. Cars average about 25% efficiency, dependent on highway/city usage. Old power plants get around 50%, and new power plants are in upwards of 80%. Much as I would love a hydrogen car all they are really doing is prolonging the enevitable. If we wait until oil runs out to develop this tech (as many perople seem to think is a peachy plan) then those technologys will work much worse.

    Americans are idiots. I can say this because I am one. Nonetheless, the value of an item is for the most part a direct function of it's scarcity. Gold is expensive because there is only so much to go around. Diamonds are expensive becasue idiotic americans think that there aren't very many of them.

    Same goes for digital gifts. Authentic ones cost money not everyone has one. Does anyone out there really thing that we are spending our money on things we need? Pet rocks?

    If I didn't have my iPod I'd be heartbroken(true) but do I need it? Well, whatever makes you happy. What else has value attached to its scarcity? Karma point maybe.... No. Couldn't be.
