  1. Re:This is nothing new on Fake "Bill Gates" Message Dupes Top Tools · · Score: 2, Informative

    SMTP works like real mail. Anyone can walk up to your mailbox and leave an envelope addressed to you from "Bill Gates". Unless you know how to look for signs that it was properly handled by the post service, you have no idea if it's real or not. We've known this since around 2400BC (because wikipedia says so).

    Actually, in the US, this is illegal, and it does get enforced. No one but the US Government is allowed to put something inside your mailbox, and you will probably find out if you try distributing leaflets for a commercial enterprise or political campaign. It may be illegal to forge an email, but that's different from delivering it.

  2. Re:WANG computers on The Twelve Most Tarnished Brands In Tech · · Score: 1

    Wang was really one of the great one-product companies, and it wasn't the product most people associate them with, word processors. An Wang invented the core memory, independently from IBM, who also invented it, but after Wang. Wang had taken the precaution of getting his notes notarized so he could prove he was first, and won a lawsuit and received huge royalties not only from IBM but everyone else, until integrated circuit RAM took over.

    Wang invested that money into other projects including calculators (desktop, programmable machines, some with integrated printers and tape drives - really small computers) and word processors, and did achieve some success with those lines in the 70's, but never established the kind of critical mass that could keep up with all the fast changes in those markets. They also never really got their minds around the real problem, which was to come up with the best software for their niche markets. Wang was always a hardware company at heart, and getting the ideal look and feel for a word processor was simply out of their league.

    Wang came up with some good OEM hardware, but really never established themselves as a company who understood the end user. In that sense I don't think they fell so much as they got passed by by the companies that understood software and their customers better.

    All logic can do is determine whether a collection of axioms and rules of inference is consistent, and if it is, what the consequences are. It can't tell you what axioms and rules of inference to adopt in order to develop a "correct" system of ethics. A classic example would be excluded middle - p|~p (p or not p). Although this is standard in mathematics, it is not absolutely necessary, and lots of mathematics can be done without it. You could argue for an eternity whether it should be part of you logical system for ethics or not, but logic alone will not tell you.

  6. Re:This is slashdot right? on New Conficker Variant Increases Its Flexibility · · Score: 4, Funny

    Because the article doesn't have any technical detail either. I would assume that the new features allow them to connect through some sort of peering mechanism, but the article doesn't go into detail.

    Well, I thought there was some useful detail in the article, particularly this:

    Overall, the modifications to Conficker B++ appear relatively minor as compared to the significant upgrade in functionality, performance, and reliability, that occurred from Conficker A to B. These smaller and more surgical changes to B appear to address some of the realities that are currently impacting Conficker's binary update strategy. In particular, in Conficker A and B, there appeared only one method to submit Win32 binaries to the digitial signature validation path, and ultimately to the CreateProcess API call. This path required the use of the Internet rendezvous point to download the binary through an HTTP transaction. Under Conficker B++, two new paths to binary validation and execution have been introduced to Conficker drones, both of which bypass the use of Internet Rendezvous points: an extension to the netapi32.dll patch and the new named pipe backdoor. These changes suggest a desire by the Conficker's authors to move away from a reliance on Internet rendezvous points to support binary update, and toward a more direct flash approach.

    However, Conficker A and B did support through the previous netapi32.dll patch an ability to accept new DLLs, as long as the shell code submitted through the RPC buffer overflow matched the original Conficker infection shell code. This approach was limiting both in the requirement that direct flashing required an easily identifiable shellcode string and a single DLL method loading procedure, both of which are now subject to detection by security software. Conficker B++ dramatically increases the flexibilty of the direct flash mechanisms, offering an ability to load digitally signed Win32 executables directly to a Conficker host.

  7. It depends on your situation on How Do I Start a University Transition To Open Source? · · Score: 1

    There has been a lot of good advice posted already, but I'll add what I can from my own experience. I was a computer science professor at a larger (~15,000) university for 20 years, and we used open source for virtually everything, but it was like pulling teeth to get the university to switch, mostly because of attitudes of people in the Data Center. The first thing, back in the 80's, was to get them to connect to the Internet. They thought their IBM Bitnet connectivity was all anyone would ever need. It was a very painful process, and people actually got fired

    The fact that you asked about how to find out what the licenses cost suggest that you feel you can't just ask the people in your Data Center. If that is true, be prepared for a long guerilla war, but you will be able to make progress. As far as finding out what those things cost, you can't just get a standard price. Every contract is negotiated individually, with all sorts of mini-grants and bundling going on to help close the deal. If you can't get the information from the Data Center, try the Purchasing office. They may be more helpful.

    In my experience, one department going its own way isn't real effective. I think that the Data Center spread the word that we were "different" and what worked for us "wouldn't work" for anyone else. Some people were puzzled as to why we never seemed to be bothered by viruses and worms, but they kept getting new stuff and it kept them happy.

    One place where we managed to get a little purchase was when money got tight, and we pointed out that dropping some licenses might be preferable to laying people off. The good thing about that is that then they had to get some people with some open-source expertise, and that's how you really make progress, when there are some open-source advoctes inside the belly of the beast.

    The most important thing is not to be impatient, and not to give up. When you get an opportunity, show the deans and vice presidents your $300 netbook, or whatever else, or show how effectively you can use open office and create documents that everyone else can use. They will start asking questions, and eventually the Data Center will have to come up with some real reasons why they go with proprietary products.

    Good luck

  8. I'm confused on GPUs Used To Crack WiFi Passwords Faster · · Score: 1, Offtopic

    First off, does this kind of approach work against any rationally designed secure software? All that would seem to be needed to defeat this is for the the login procedure to have a few seconds of delay before it responds yes or no, and no speedup in the guessing will help. This is why we have shadow password files, right? Or have I just been using *nix too long?

    Also, I've seen people using GPUs in all sorts of non-graphics computation environments for some time now. When push comes to shove, is this just about money, and that CPUs have extra features that makes it easier to run an operating system, but aren't needed for pure computation? I'm not a hardware guy, so this is probably a stupid question, but I just don't get it.

  9. Re: How Long Should Open Source Project Support Us on How Long Should an Open Source Project Support Users? · · Score: 2, Insightful

    I don't agree. I think there is an obligation to do something, but not necessarily for that project. If you are putting in 30 hours a week, or more, to one widely used open source project, there is no need for you to support other ones, no matter how much you use them

    Some people would go further and say if you are donating your time to any worthy cause, it absolves you of the responsibility to provide any support to F/OSS. That water is a little murky for my taste, especially when deciding what causes are "worthy", e.g., a political campaign, or converting people to your chosen religion. But I view F/OSS as one community, and while we all have to be involved, we don't have to be involved in every project that we use.

    Exactly. If you want support from an open source project, you need to help that project out. Whether that's in the form of development work, testing, documentation writing, helping uses in the forums or lists out, or good old fashioned cash depends on what the project needs. Most projects are more than happy to list what they need, and if they don't, e-mail the project's lead(s) or e-mail their support list -- they'll be very happy to hear from you.

    That strategy worked great for Apple back in the late 1970s / early 1980s. Get Apples in front of schoolchildren and by the time the IBM PC came along it was too late. Kids were already in love with the Apples, and many "stuck with what they knew." It was the most effective long term marketing move Apple ever could have made, and I doubt they even realized it at the time.

    Times have changed, though, and the ability to monopolize the hearts and minds of kids with the only computer they're exposed to is long gone. Many of the kids will already have PCs at home, many will have (or at least have played) X-Boxes, PS3s, Wiis and a host of other devices, including smart phones. I don't think this can have the same social effect that Apple had on us 30 years ago, because the environment is now so different. The novelty won't be there.

    I agree, but there is still something very positive for Linux going on here, and that is that now Microsoft has to run around trying to put out fires like this one, and has less time to spend doing... other things. I know that people here think Microsoft has more money than God, but eventually the moles start popping up faster than you can whack them down, and you have to start losing some.

  14. Science vs. Scientific Method on Are US Voters Informed Enough About Science? · · Score: 3, Insightful

    The problem is not that people aren't informed about science, but that they aren't informed about the scientific method.

    Scientific Creationists come up with a "theory" and present it as some sort of equal competitor with Evolution. The notion that a theory has to allow one to make predictions, and to test the theory with experiments, and thus to be experimentally falsifiable, isn't well understood, and it is critical. Scientific Creationists would never admit of an experiment which, if performed, could prove their theory was wrong as stated, and needed modification or simply had to be discarded. This is what makes Creationism dogma and not scientific.

    This extends to popular opinions about controversial scientific questions, like Global Warming. Everyone from George Will to Al Franken has an opinion about the subject, and all but a handful of them desperately avoided taking a college course that involved labs and any real interaction with the scientific method when they had the chance. But they figure they have as much right as anyone else to weigh in on the subject.

    Of course, they do have such a right, but it doesn't help the general understanding when they ignore the scientific method, which they do not understand, but claim that their innate intelligence allows them to understand something which scientists have to sweat over for years.

    The net result, I fear, is a "science without tears" society, where students are given to believe that it is not necessary to actually study a subject in order to assert a competence in it. Employers may want to see certain courses on the transcript, but public policy won't be driven by fact and empirical observation - it will be driven (moreso than it already is) by who has the biggest microphone.

    ...are a big part of it. If you develop some software, and get it out there where people can try it, and comment on it, and you can react to those comments, it says a great deal about the skill set you possess. Generally speaking, open source is going to be the quickest way to accomplish this.

    Our CS students seem to understand this innately - many of them develop open source projects - small, relatively specialized ones that are appropriate to to some of the specialties that exist in our department. To some extent, they have trained the local employers, who now want to see what kind of project the student has completed and what kind of reaction it gets from its community.

    The problem, however, is that our department has been slanted in this direction for a long time, using Linux and other FOSS for just about everything, so we attract students and prospective employers who appreciate that. There may be a large cadre of local employers who feel ill-served by our approach, but if they exist they are almost invisible to us.

    I disagree with your point that it was Microsoft that brought "unification to the desktop", a point that is often repeated.

    It was IBM, not least through there open hardware policy, that wiped out any significant competition and brought a single platform to the desktop. Microsoft, very shrewdly, hung on for the ride and then jumped off at just the right time. It was a brilliant business plan, maybe the most perfectly executed business plan ever, but they were not the ones that created the common platform. Nor did MSOffice, et al, accomplish anything in that department other than bring most of the desktop under the auspices of the same company. Heck, they completely blew it in the database department, after acquiring the most promising company out there, Fox. IE did nothing for "unification", quite the contrary, and the list goes on with malware protection, email clients, and all the other standard stuff on the desktop.
