  2. Re:Oh. You wanna *start* w/an OS? on Computer Science Curriculum Using Linux? · · Score: 5

    I took the CMU OS course as a junior all those many years ago... And I must say that it was quite possibly the most educational CS course I have taken.

    As aheitner posted above, it runs using specialized emulatorsm not to make the architecture more manageable, but as a sandbox or virutal machine for the OS you are writing.

    When I took OS, there were 3 projects:
    1) write a basic priority based scheduler. Time: 2 weeks, solo project.
    2) Write a kernel. Time: 6 weeks, solo project. In reality it took three weeks of constant coding. We implemented ISR's, memory management, fork, exec, wait, sleep, read, write, malloc, and another 10 basic OS functions I cannot remember. I wrote a kernel.
    3) Complete Filesystem. Time: 4 weeks, with a partner. We wrote a complete filesystem

    The projects varied depending on who the professor was for that semester. The other semesters projects were all partner oriented which allowed them the time to do things like terminals/shells and kernel threads.

    I do not understand why people are looking for projects that tweak the OS itself, or add to it. I learned so much about OS and about myself and my abilities by having a 6 page project spec dumped in my lap and being told "here ya go. Have fun. You have the TA's office hours."

    It's like learning to drive a car. Sure there's a manual that you can study, and you can sit in the drivers seat for a while and play with the blinkers and the wind sheild wipers while going "vroom! vroom!" but unless you have someone force you to learn to drive, you'll never know how good your skills really are.

    Talking about advanced capabilites in an OS course is all well and good, but save it for grad courses. An undergrad course should be about the kernel and basic resource management.

  3. uh... i'm confused... on Open Source Symbolic Math Program? · · Score: 2

    " On occasion I've used
    Mathematica or Maple to simplify the process, but only rarely
    because (i) they're not much better than plain paper and pen, and (ii)
    they're proprietary software, and if I'm going to learn someone's arcane command
    syntax, I want to make sure it's open source so I can compile and run it
    everywhere I need it."


    It's the "run it everywhere I need it" part that is confusing me. Don't the major packages have ports for all major platforms? I have seen/used UNIX, Mac, and PC versions of Mathematica, matlab, and maple. I have not had any trouble with transfering session data (mathematica notebooks, matlab log/diary files, etc...) between platforms either.

    I remember taking a mathematica course 6 years ago at CMU and using the UI on a PowerPC mac, and running the bigtime number crunching on a Sparc20 server.

    I am in no way trying to negate or discourage the need for, or advantages of, an open source solution to the problem, but shouldn't a quantum chemist have enough university or corporate support to provide him with whatever packages he needs to do his job?

  6. microsoft natural on Ergonomic Keyboards · · Score: 2

    So I'm a 23 year old software developer, and I used to have major pain in my wrists and sometimes fingers (joint inflamation). I fully blame the problem on poor ergonomics. This is very very serious. If I am having this much trouble now, what will happen in 3-5 years? Will I have to stop typing? Stop coding? What would I do for a living?

    The thing with ergonomics is that, even though you can now go out and by a nice curved keyboard (I'm a big fan of the microsoft natural), it is still designed for a mythical "average user". Your basic compUSA keyboard is not guaranteed to work for everyone.

    I have adapted to my natural keyboard, so much that to use another keyboard causes me wrist pain within 5 minutes. This even occurs sometimes between home (the original big beast of a microsoft natural) and work (the slim elite version). I dread using my dad's laptop to respond to email when I visit.

    I think that I'm going to have to shell out the $200-300 for one of the kinesis keyboards. The cost is easially justified if it works.

    But what will I do if I adjust to that one also?

  8. Sony doesn't want PSX2 to replace the PC... on PSX2 To Replace Your PC? · · Score: 3

    IT's not about replacing the PC. Sony's much too evil for that. (quite frankly, Microsoft pales in comparison...)

    The PSX2 will be the core of Sony's "home entertainment universe" (remember their new commercials about how all their stuff is interconnected? What's missing? hmmm...). It is designed as the gateway unit for all of your home multimedia equipment, this includes your PC if it is equiped with 1394 oops I mean firewire oops I mean iLink Sony's proprietary protocol built on top of 1394.

    Sony has come out publicly to state that PSX2 is a settop box, which is not the same genre of equipment as a game console. PSX2 is Sony's bid to completely and totally control your living room.

    There's a company called Bleem that makes PSX2 emulation software for the PC. They made about 4 million in sales last year. Sony has spent about 10 million so far trying to shut them down. Why should they care when they sell their consoles at a loss and Tekken3 was their highest grossing product last year? Becuase if you can play playstation games on your PC you don't need a playstation, or the PSX2. The PSX2 is what will enable you to take your Sony camcorder, and plug it into your home network to connect to your Sony TV, Sony VAIO computer, and your Sony microwave, bathroom scale and toothbrush.

    So of course you will see all kinds of releases about how great and wonderfull emotion engine is and how PSX2 (*cough*with-iLink*cough*) will make everyone's lives easier and better and make you more attractive to members of the opposite sex.

    Patiently I await Dolphin or NUON.

  11. Re:I misread the title, but it gave me an idea any on Distributed.net CSC Success · · Score: 3

    I think the other posters to this comment are misunderstanding the author's point.

    The issue at hand is not that CSS is "simple" to break. The issue is, should a CSS case be brought up in court by the Big Bad Lawyers, what would happen?

    It is understood be the technical community that CSS encryption is pretty much useless as a copy protection scheme. But how can this be proven to a jury? Expecially when $500-$1000 per hour lawyers are employed by the adversary?

    distributed.net is a known and proven source for ranking the status of encryption. They are not a malicous orgainization, but rather a testbed, placing an encryption technology under intense scrutiny and forcing it to prove it's worth. Where CSS (or its relacement) placed under such scrutiny, the results may be enough to have future lawsuits thrown out of court. (and therefore lessening the slashdot posts/comments on this subject... no offense, but it is getting kind of old. There is very little new information on the subject left)

  15. this is a standard buyout action... on Metrowerks Putting Linux on Hold · · Score: 4

    Jeez. Chill.

    Metroworks is a tools company that was just bought by Motorola, a major international corporation that has a completely different way of working.

    Anytime there is a buyout like this, the smaller company will go through a months long period of adjustment and resource re-allocation to be (for lack of a better word) assimilated. Becuase of these changes in company focus, there will be a number of products that are put on hold, especially smaller projects such as linux codewarrior.

    Codewarrior will not killed off. It's one of the leading development environments for Mac's. Therefore Motorola has a vested interest in keeping it going becuase they make Apple's chips.

    Once the realignment is complete, Metroworks will probably pick up the projects that were put on hold. If they had not recognized the value of linux tools, they would not have started the project in the first place.

    Note that Motorola Computer Group was one of the first people to sign on for embedded linux. I would not be surprised if MCG has already started apply intra-corporate pressure to have the linux codewarrior project continued.

  17. I have a problem with this essay on ESR on Quake 1 Open Source Troubles · · Score: 2

    I am actually a little bit insulted that the Quake release was used as an excuse for ESR to wave the "Open SOurce will eventually solve everything including world hunger" flag. (yes, I do participate in open source development regularly.)

    The concept that the quake cheats would not have occured if the development had been open source is an interesting one:

    If Quake had been designed to be open-source from the beginning, the performance hack
    that makes see-around-corners possible could never have been considered -- and either
    the design wouldn't have depended on millisecond packet timing at all, or aim-bot
    recognition would have been built in to the server from the beginning. This teaches our
    most important lesson -- that open source is the key to security because it changes the
    behavior of developers.


    BUT.

    The problem here is not the developers Nor is it aimbots. It's because of bots that we have Quake III Arena today. The issue is that people abused the source code for completely selfish reasons. These people were not developers of the software. Making the project open source from the begining will not change the behavior of cheaters.

    If quake had been designed to run securely on T1 lines and handle transaction rollbacks I could see spending the time to write a 4-5 page article explaining why it's security model has issues. But Quake is an old game A game designed to run on Pentium 90's and 14.4 modems. It's like having a doctoral disertaion panel to grade a sophmore's CS project. (just talkin' about the security model here, not the entire game). This is more of an "Oops. Sorry. We'll fix it next time" deal.
