    I know it has been a LONG TIME since high school algebra, but the imaginary number, i, equals the square root of -1. Where did you get 2 / 0 = i from that page? Everything I ever learned in math (I went through diff. eq. in college.), always defined a real number divided by 0 as the limit x->0 for R / x. Of course depending on which way you approach this is either infinity or negative infinity. So maybe you are thinking inf and not i.

    In regards to proprietary graphics drivers. They are proprietary because we tolerate them. If the day NVIDIA had released those drivers the kernel developers had asked the FSF to send a cease and desist to NVIDIA, we probably would have full open source 3d accelerated drivers the very next day.

    Actually, I have to agree with the other child post, they would say F-CK YOU, and drop Linux support. Your response is to claim they want in on the embedded Linux devices market, which is a market that does not rely heavily on 3D graphics. Even those embedded systems that use 3D acceleration are typically lower power systems. More then likely, if pressed nVidia would simply release to us a very limited open source driver with many customizations and optimizations removed. These drivers would effectively be useless. You can argue that we could then improve upon them and make them better; however, many people are trying to help expand the reach and acceptance of Linux. If we wind up with 90 different versions of video card drivers or poor performing drivers (the current ones aren't necessarily great), many people are going to be turned off and do as you said before: if I want proprietary drivers, I guess I will have to use Windows or Mac.

    As for patents. There is no question. No-one even looks at Microsoft's patents before they make these wild claims that GNU/Linux doesn't infringe on any of them. Write more than a couple of thousand lines of code and you're almost certainly violating someone's patent, why not Microsoft's?

    There is almost an implied no-sue agreement with large corporations holding patents. HP and IBM are two huge open source supporters with many Unix and Linux based systems available in the server market, not to mention tons of contributions to Open Source projects. These two companies also have huge patent portfolios, I think I saw a stat that IBM has something like 10% of the software patents. The reason I think Microsoft will only sue Linux as a last result (By which I mean, Linux is victorious and Microsoft is a floundering company.), they fear that IBM will let loose on them. I think them and others are surprised/afraid at how IBM did not rollover to SCO and are literally sucking the company dry. Granted, doing this to Microsoft would be a lot harder, but I suspect that it would be highly frowned upon by most everyone else in the computer industry if Microsoft went after Linux.

    As for this: you have to accept we do not all agree with you all the time. No I don't. I can try to convince you. Or you can try to convince me. And in agreement we might find something even better: truth.

    We can argue all day. I am a pretty stubborn person, but you are welcome to try to convince me. Honestly, I tend to stick to an open-source ideology and support OSI more then I do FSF, mostly because RMS just rubs me the wrong way. Remember my comment about zealots. People really do not want emotional over-the-top demonstrations and speeches to attempt to show them what is wrong with software and companies like Microsoft. It actually turns a lot of people off, especially those who do not fully understand the information trying to be presented. In the end, a lot of people are more logical then we give them credit for, even if their logic is sometimes quite flawed.

    Actually, his statement is not entirely wrong here. In the legal since, they may not be violating a copyright because they can be invalidated in court. It is not like copyright where it is relatively cut and dry, until fair-use comes into play. Patents are currently an icky mess, and I think a big reason you do not see these lawsuits against Linux with all these patents is because they know their house of cards will come tumbling down. OH, and because IBM could put Microsoft into patent litigation until we are all dead with their patent portfolio. They received an estimated 5,000 patents in two years alone. Note who isn't on this list.

    Now, why shouldn't we want to run proprietary drivers? The grandparent's point is valid: if you want to use proprietary software in a "free" environment, then why can't you? He is arguing that he doesn't care about proprietary or free; he like many people truly believe that Unix-based and Unix-like systems are superior to Windows. One of the system's he uses is proprietary to some level, Mac, the other is free. If the X group can make drives that actually run 3D well, particularly OpenGL apps, then let me know. I have never been able to get games working in Linux without those drivers. I do not mind spending a bit of time to get them working in Linux, and I do not want to waste the time on rebooting for a dual boot. Also, there are plenty of native games that need that extra support: UT2004 and NWN being the big two I own.

    Like the other child post stated, you have to accept we do not all agree with you all the time. There are plenty of problems with both proprietary software and open-source or free software, whichever phrase you tend to lean towards. Your "friend", Bruce, and the OSI tend to prefer open-source to the RMS/FSF definition of free software. Anyone who claims there is nothing wrong with their method is trying to sell something. I have seen this from both sides, and it is truly pathetic to watch some zealots push Linux, OpenOffice, Firefox, or some other free alternative...if Microsoft made a truly superior product, which I would love to see them try, with no bugs and excellent performance, while using perfectly open document standards...people would still complain because it is proprietary and they cannot see the code...we will use our buggy, broke system instead. Zealotry is not very becoming.

  5. Re:an inside story on Indian College Students Face Bleak Prospects · · Score: 1

    This is no joke. I can tell you a story from the inside. Once I tried to interest my faculty colleagues at a Large University That Will Not Be Named Here in setting up an exit exam for our degree program. A big comprehensive bugger that would "certify" our graduates in a measureable way and in particular specific skills. (This is in a scientific/technical field, by the way, so such skills are easy to define.)

    Let me tell you a story of a truly large university, Ohio State. There are not many in the US with a higher undergraduate enrollment. There are a few reasons why "certifying" your graduates is unnecessary and hard. First, let's discuss unnecessary. We have ABET. Not the greatest system in the world, but graduating from an ABET accredited institute is about all you need for most employers. It should be noted, a lot of these employers do not care. An "exit exam" would also prove very little, since it is merely a test, and there are plenty of people who can test much better than they study. For engineers, we have the PE exams. This is not taken by all and is practically worthless to some people. I honestly do not know many EE students who took the exam unless they were very heavy into the power-end of EE.

    Now to hard. There becomes the undying question of what to ask. For example, at Ohio State, an EE student can easily take courses in a wide variety of fields. You can do digital design, microprocessor based systems, VLSI circuits, digital signals and systems, signal processing, power, RF, and the list continues. How do you test these students? They actually have very little course work in common. Most of the course work they share is low-level circuits classes. Does it really matter to an employer that I can interpret a simple circuit design, or even a really complex one? My field is computer networking, digital design and VLSI circuits. I honestly do not think I have had to handle a simple circuit design since I graduated, and if I did, it was so simple, you probably learned to solve it in a high school physics class when learning about electricity.

    Since every graduate has passed the exam, a firm or graduate school knows for sure and in detail what graduates of this particular program know. That's the kind of gold-plated guarantee of competence that makes employers feel all warm and fuzzy about you when you turn up for your job interview looking appallingly young, like you started shaving yesterday.

    The unreliability of testing methods makes this no better than using your GPA and transcript. Coming out of college you have very little work experience. If you are in a technical field, perhaps you will be luck enough to have a co-op or internship to rely on as experience, or the company you worked for will give you a full-time job. This notion that a test is somehow better than using grades is really bad. Look at all the complaints about using the SAT or ACT for a major acceptance requirement to college.

    About the guarantee comment, have you ever worked in the private sector? I really doubt most places are going to care if you had an exit exam. I wouldn't be surprised if you could get away with lying that you did have one. This is really a crock. I believe my piece of paper is a tad bit overrated, but trust me, employers are not going to use an exit exam as some shining badge over other candidates.

    I couldn't even find out what happened to our graduates -- who had hired them, what fields and types of positions they'd gone into. The data had never been collected, and no one was interested in doing so. Amazing. Blew my mind, I tell you.

    Linux is harder to set up, thus it will be more expensive for governments to switch over to linux because it takes more time to set it up.
    There is common misconception #1. There are plenty of easy to install, easy to setup, and easy to maintain distributions. Almost all of these have free flavors without having to pay a ton of money. I believe Mandriva can be installed and setup without too much external help, and it is hardly a beast to figure out. It is also ahead of Windows because you do not have to waste time setting up the other software, like Office, since it is installed at the beginning for you.

    Whereas with Windows, after being in the market for so long and having a lot of people at least be exposed to it once or twice in their lifetime, will not require as much time compared to linux.
    I challenge you to get most average users through a Windows install. Guiding my brother through a re-install on his laptop was one of the most painful experiences I have ever been through. Once again, a proper distro of Linux is no harder to setup and install then Windows. It also works out of the box, unlike Windows which requires Office, your IE plugins, security patches galore, etc.

    Once linux has the same support, features, ease-of-use as Windows has then it has a chance of succeeding and taking a good chunk of market share.
    You do not need to start with market share to be successful. If this were the case, nothing would ever catch up to Windows. Also, Linux quite possibly has superior support to Windows. Have you tried to deal with a technical rep at Windows about any problem? If they do not try to hand you off to your PC vendor, they will talk in circles until your head spins. Trust me, Microsoft did not get big by offering great support.

    But as linux continues to be protrayed as the geekdom of software, it will not be a cheaper solution to Windows.
    Cost of Linux distro, $0. (Fedora, OpenSuse, Ubuntu, you get the idea)
    Cost of Windows XP Pro, $299 at retail, $150 typically for OEM.

    You do the math.

    yet I though that CSS was not broken because they cracked the weak cipher, but rather because whoever made the XING software DVD Player forgot to encrypt the decryption key or something like that.

    I am not sure what initial method was used to break CSS; however, CSS was found to be somewhat receptable to brute force attacks, which is a good sign of crypto weakness. The reason for its weakness is due in some part (or completely) to the US export restrictions on strong cryptography.

    Encryption is usually about everybody not having the password

    Gah! Passwords are the evil anti-cryptography. The problem with a password is they are usually poorly designed and typically susceptible to the dumbest of attacks - the dictionary attack.

    so if every agent in an airport has it, or if every DVD player has it inside, there's no way it can be really secure. You basically want "everybody" to decrypt the data... not a surprise if they're able to.

    My understanding from the article was that the key is unique to each passport. Each passport's key is then either directly provided to the reader or established using the three values in question. This could be fixed using several different methods designed for establishing key values. They could have used Diffie-Hellman key agreement to establish the secret symmetric key. This key value would then be used for encryption. I suppose the only flaw here would be the RFID passport would need a space to store the established key.

    You could also generate and store a key value that was generated using an RNG. Each station could then generate RSA key pairs and transmit a public key to the RFID, which would encrypt its symmetric key and transmit it back to the reader. The reader would then use its private key to decrypt the symmetric key. You could then generate different key pairs for each time a card is read. Again, I suppose a problem develops with where to store the public key.

    There are plenty of ways to keep the secret key from being known. In this case, a bad choice was made in choosing how the key value is derived.

    What fundamental principle of encryption are they breaking? If anything, a fundamental principle of encryption is that there can't be such a thing as a "secret key" if you're either putting it in the passport or if you're deploying it to everybody that needs to scan passports (remember DVD encryption?).
    Okay, that you for showing you have no understanding of cryptography. The problem with DVD encryption is that is what a weak cipher. It is built on a 40-bit key (mistake one) and a stream cipher (potential mistake two). This weak encryption method was the real problem with CSS, not some fundamental flaw of cryptography. There are plenty of ways to have a true secret key. A secret key in cryptography is any symmetric key that is meant to be kept, well secret. These keys can be established using DH or by using an RSA keypair. Neither of these have been broken, and would be very secure for establishing keys for the RFID system.

    What's important is to have the data in the passport (along with the picture) digitally signed, in order to avoid tampering. The article claims that these passports are indeed signed and they didn't break the signature. Big surprise, since all they did was get a RFID reader and decrypt 3DES with the key right in front of them.
    Exactly! The 3DES key, well the two or three DES keys, was right in front of them because it was created from non-secret information stored in the passport. This means the data is publicly available and required no key information to read.

    I do not get your claim that this is total FUD. Your "secure" passport can be broken. I believe a good dose of Fear that is doesn't work, Uncertainty that it does work (cause it obviously doesn't), and overall doubt of the system is in order here. There are plenty of ways they could have successfully secured this system. It is a design flaw brought about by the failing to follow the "rules of cryptography" and that is something to be worried about.
