    At the very least, if it's an intentional hole you could be obliged to do a lot more than that. You're lucky if you put a backdoor in and you only have to spend the time to fix it. If I bought something from you and deployed it into production and you have a backdoor in it that was used by someone, you'd wish you never meet me or my company's lawyers by the time it was all said and done.

    People are buying "hacker insurance." Think about that, the insurance industry is getting involved. More importantly, in a smaller to mid-sized operation a good security breech could be the end of the company. You could potentially go to jail for something like that. It's a stupid practice.

  4. 2.5 is the bomb so far, in so many ways.. on Anticipatory Scheduler in Kernel 2.5+ Benchmarked · · Score: 5, Insightful
    They should really call it 3.0...

    When I first started hacking on Linux, I was working with a seasoned Linux kernel hacker who my company hired as a consultant. He helped us with some I/O issues and such, did some other tweaks and gave us a ton of inspiration to go get after it ourselves. (You be amazed at how many people are afraid to just start making changes to kernel code) He is a wickedly cool individual and as someone whose had a lot of schooling and experience it was one of the best learning experiences I can remember.

    The first thing I started dorking with after that experience was the scheduler because I, like all other hakers, know how to schedule stuff. At the time, (early 2.x) the scheduler was also a fairly easy to digest piece of code that could have impacts on the system in great ways.

    Well all my stuff got bit bucketed. I called up our consultant guy who my friend by now, "what's the deal? Linus doesn't like my stuff. How do you mail him stuff?" And his answer was that pretty much every body wants to tweak the scheduler, everybody sends stuff in. Linus is sage in his wisdom, schedulers are freaking hard because there is always a pedantic worst case that sucks and actually shows up in the real world. Linus has always done fairly simple things that aren't best but certainly aren't worst. So 2.0 had pretty straight round robin. 2.2 and 2.4 they started to add queuing schedulers with niceness. 2.5 we're going to get a pretty killer scheduler that has taken a ton of effort to tweak and there are still discussions to expose parameters to the user via /proc or something because you can find cases were it doesn't perform as well.

    Now this IO scheduler is opening up a whole new can of worms, it's a new chunk of code called "scheduler" and all hackers know scheduling. In the past it has been fairly simple. It should be fun to watch and the kernel is going to kick mucho ass in the end. There will be a lot of talk and debate about this stuff. It's also distilled down to the trusted set that Linus will let play with things called "scheduler"

  6. Any of you read Fortune? on Linus Has Harsh Words For Itanium · · Score: 4, Insightful
    The Feb 17th issue broke it down nicely. You can read it on their web site. Basically. The conventional wisdom is that there are exactly 2 players in the 64bit arena: IBM and Intel. IBM isn't jumping on the Itanic either, at least not in any big way other than building some low end servers with it.

    AMD is the wildcard. If x86-64 is the bomb and takes off like AMD is betting on it. Intel lost the 64bit war for many years. IBM and maybe even Sun will quietly (well sun doesn't do jack shit quietly) push x86-64 for the low end while IBM POWER4 and POWER5 and POWER6 down the road run the big end.

    Basically Intel needs something like Sun to jump on it IA64 to really give it some credibility and they don't sound real eager to. IBM sounds like they are down for the fight. Alpha, MIPS, PARISC are all pretty dead; long term and relatively speaking. Meanwhile, if Intel doesn't get on the shit quick then they'll have to support x86-64 too and that's the real death blow to IA64.

  9. The shuttle is obsolete. on More on Columbia · · Score: 3, Insightful
    NASA needs to move on. I think NASA threw the dice way back when, they lost but they've been trying to make it look successful ever since. It's far more expensive to fly the shuttle than it was to use the single use rockets we used before and they were more reliable now that 14 people have been killed in the shuttle.

    It's simple math and economics. Financially the shuttle program has been a terrible disaster. Now you can't second guess anything and there have been advances in comfort and living conditions in space and such thanks to the shuttle but I'm sure the same kind of things would have been done without it. We've learned things because of the shuttle, it hasn't stopped science, it's just not delivered what it was supposed to have.

    I also fear that NASA itself may be out of date and obsolete. Am I the only one who is disgusted by the notion of the beaurocracy? There are all of these emails surfacing. I've worked at IBM and other big places and I get this sick feeling of CYA going on. I can just see the Dilbert-esque rocket scientist sitting at his desk composing the emails to the director about the foam falling off and the other possible causes. "Properly documenting" the risk. I've read Feynman's report on the Challenger disaster and that's one of the issues he pointed out. The administration lives in make believe where the engineers make compromises to do things on time. It's kind of a bummer because there are people that die because of it. I'd like to think that someone will be held accountable, I doubt that anybody other than an administrative warm body will be and at best they'll be fired and get a really high paying job at Boeing, TRW, or Raytheon.

    I think it's high time we start looking at splitting NASA up in to 2 or 3 groups and making them compete with each other. Let the beaurocracy die and the science come back, make them write proposals, beg congress and private parties for funding and then hold them accountable for delivery. Let different groups take different approaches. Reward success with continued funding. NASA is cheap, relatively speaking. We can easily fund 3 NASAs. Right now it all rides on the success and failure of one entity with nearly an impossible mission, logisitally speaking. NASA can't even admit that the shuttle program is a failure because then they lose face and funding and there isn't another organization in place to do the science. So science continues to limp and NASA continues to put bandaids on a very expensive wound that has taken more lives than all other space related accidents put together.

    And for the record I am appriciative and recognize the hard work and accomplishments of everyone associated with the shuttle program. They have engineered some amazing things and I'm not attacking anybody personally. It's the program as a whole that hasn't delivered what it promised.

    Well how do you think the pass phrase factors in to that equation? Seriously. Do the math for El Gamal or RSA, I don't see a "passphrase" component.

    They use a symmetric cipher to encrypt your private key on disk. Depending on which cipher is used, likey IDEA, AES or 3DES. You're looking at a 112, 128, 168, 192, or 256bit symmetric block cipher and the effort it takes to break that. RFC 2440 states that a hash is applied to your pass phrase to expand it or reduce it to the proper key space (your 70character phrase doesn't buy you any more than a 32character phrase,) MD5 or SHA is probably used and then a cipher which isn't specified. However MD5 and IDEA are chosen for backwards compatibility, implicitely.

    So how long does it take to decrypt an IDEA encrypted message? 64bit blocks, 128bit key space. A lot less time than it does to factor a 4096bit Blum integer.

    I like Mandrake a lot. My path went SLS to Slackware to Redhat to Mandrake with 2 Debian machines thrown in. I'm a kernel hacker and an embedded programmer and have been on UNIX since the mid-1980's. I've also got a few of degrees, including an advanced one. I'm not Alan Cox or Linus but I'm not exacly a newbie either. Technically, until 8.2, Mandrake was on par with anything. I've yet to hear a substantiated argument that it's not, just hearsay from people who couldn't get their sound to work or install fonts and probably, IMO, couldn't properly adminstrate any version of Linux or UNIX. Please follow up if you want to refute this point. I'm only bringing it up because I'm sick of the bashing going on, go bash UnitedLinux or those pricks at Lindows.

    Out of the box, it comes more secure than I tend to believe Redhat or SuSE does; particularly with the high and paranoid options. It's easy to set up and they have a ton of contrib packages, I rarely find them lacking an RPM for anything, which is very important for RPM based distributions, nothing can screw them up faster than willy-nilly compiling and installation of packages from source that the RPM database can't manage. I like that packages are there when you want them.

    Now there are some stylistic things, but I can't find anything to complain about with Mandrake that I couldn't complain about in all non-BSD platforms. It's also just style, if you're admining all day then you're probably not writing code or being productive. I don't know maybe I'm not "IT department" enough to be able to bitch about admining a box. I throw Linux on a box and write code. I guess if you don't like graphics for some reason or really dislike GUIs then you probably wouldn't be happy with Mandrake. Big deal. Again, follow up with some specifics if you'd like to refute this.

    Now in the 8.2 days I personally think they lost a bit of their edge, primarily because they've been running like a bat out of hell from financial problems and because Redhat is looking hard at the desktop and produced a killer app with blue curve. Nothing that can't be fixed but definitely not the same quality we were used to. Also there has been a lot more input and submissions from the user community at large. 9.0 is a bit better and you can easily see them getting back to form as they get used to the new operation style. It already looks like a community driven distribution. So what do you mean Ben? Do you want to fork? Go for it, like you've said, their code is GPL, I might go with you. Are you asking for someone to rise to the occasion and start driving project "Freedrake"? Or are you throwing salt in the wounds?
