  1. Re:Complain on BBC Links Linux To MyDoom · · Score: 1

    Done. The probable sources are either spammers or the infowar community. The Russian term, 'maskerovka' seems to apply.

  2. Re:Bring it down if you don't continue using it. on NASA to Reconsider Hubble Decision · · Score: 1

    He was a heat shield designer.

  3. Re:Bring it down if you don't continue using it. on NASA to Reconsider Hubble Decision · · Score: 1

    My kids got to go inside a real Soyuz back in 1979--I don't think they've ever forgotten the experience. The problem with the Hubble is that the reliability of the Shuttle isn't that great. At least the crew would be able to inspect the shield before reentry. Bring back the Apollo capsules! (We have a chunk of the Apollo 13 heat shield at the house--my father-in-law did the engineering.)

  4. Second Careers on Switching from Another Industry to Engineering/CS? · · Score: 1

    I broke out of the industry, doing a late PhD in neuroscience. My specialty is computational modeling of the auditory system, so I did keep a foot in CS. My current position is senior lecturer of computing, where I teach advanced object oriented design and computer security in addition to neuroscience and computation science, but still I broke out rather than in.

    I would recommend looking at computational biology or medicine as a good compromise.

  5. Robotic Science on Scientists Invent Scientist · · Score: 1

    This is extremely impressive--we'd like to do something similar with robots at Sunderland.

  6. Robotic Animals on Army Looks at Robotic Dogs · · Score: 4, Interesting

    At Sunderland, we're working on a 'robotic sheepdog' to help find victims in building collapses or similar disasters. This would be able to track its controller acoustically and use similar technology to localize and track sound streams of interest.

  7. I knowwhat my motives are.... on Blockbuster Chief: End DVD Region Codes · · Score: 1

    My Mac PowerBook G4 is a Region 1 machine and can't play the UK DVDs, which I have to play on my older PowerBook G3. The G4 is better at playing DVDs, so I'd like to be able to use it.

  8. Re:Hype on Viewing Inside the Earth · · Score: 4, Informative

    Yes, the inversion problem is potentially ambiguous. I haven't my copy of the article yet, but I will be interested in seeing how they address these criticisms. Plumes originating above the thermal boundary may have originally originated at the boundary and are no longer being fed. The base of the column continues to rise due to its lower density. Yellowstone may be in this category, given its age. The issues appear similar to those in atmospheric and hydrospheric modeling that involve chaotic dynamics.

  9. 5+/- 2 on Web 'Rules' Changing? · · Score: 3, Interesting

    I teach my students that, but in the context of the number of major elements to have in a system. I also tell them 3-15 is the range to be in. My point is that a system should have that number of subsystems to be 1) grokable, and 2) sufficiently complex to be worth defining.

  10. Re:Global Warming on Climate Data Re-examined (updated) · · Score: 1

    I'm disturbed this comment was moderated down, since it's quite insightful. The coupling between solar radiation and the atmosphere is via heating of the surface and particles in the atmosphere and involves the albedo of the Earth.

  11. Re:Global Warming on Climate Data Re-examined (updated) · · Score: 1

    Yep. The problem is that the dynamics and heat transfer become more chaotic, so everything gets worse. That's not good for anyone who needs predictable weather, like farmers.

  12. Global Warming on Climate Data Re-examined (updated) · · Score: 4, Interesting

    About twenty years ago, there was a conference on global warming held at Caltech. The gist of the results presented was that adding energy to the atmosphere seemed to make it more chaotic. That doesn't imply local warming must occur, but rather that the weather becomes more unpredictable. I think we're seeing that now in the data.

  13. Amazon Patent on Patent Sought For Amazon Marketplace · · Score: 1

    If they don't attempt to patent it; someone else will--and then where will they be? As long as the PTO continues to approve these kinds of patents, good businessmen will apply for them in self-defense.

  14. fMRI and Advertising on fMRI + Marketing = Consumer Control? · · Score: 1

    The research described in the article is actually well-advanced--we're beginning to localize higher mental functions. Once the fundies notice this, their reaction should make their crusade against evolution look like small bananas. Why? Because this is one of the trains of experimental evidence that neuroscientists have used to demonstrate that the soul almost certainly does not exist in the religious sense. See http://www.infidels.org/library/modern/keith_augus tine/no-soul.html for a discussion.

  15. Re:Blind Users on Baffling the Spam Bots · · Score: 1

    Use an audio interface and embed the message in nonobtrusive background clutter. Speech recognition software is very bad at handling that sort of requirement.

  16. Re:Spam ruins networks; here's what spammers think on Spam Slows Australian Net Traffic · · Score: 1

    And incidently creating exploitable resources for unfriendly infowar folks...

  17. Spam Surges on Spam Slows Australian Net Traffic · · Score: 1

    This seems to be a general problem. This morning I received about 400 spam messages that had accumulated overnight in one of my e-mail accounts. I don't ever use that address, but I do monitor it for messages from the ISP. About a week ago, I received 240 spam messages that had similarly accumulated overnight in another account--one that I use but supposedly spam-filtered. All I can hope is that skilled analysts are monitoring events and are preparing a mousetrap for the perps. Couldn't happen to more deserving folks...

  18. Re:The Socialist solution... on Electric Grid is a Vast Machine · · Score: 1

    The problem you're likely to run into is that central planning requires the solution of a very large sparse input-output matrix. That's a very hard problem that's easy to get wrong, as is frequently demonstrated here in the UK.

  19. Re:Not a strong follower on Motorola To Spin Off Chip Division · · Score: 5, Interesting

    The main problem for Apple was that Motorola found making slower chips for embedded systems to be more profitable than making faster ones for computers. So Apple turned to IBM, which does make computers and understands the issues. The new G5 is very competitive.

  20. Beyond Fear on Beyond Fear · · Score: 2, Interesting

    I teach security to novices, and I have found Bruce's books extremely useful resources. As soon as read Beyond Fear, I incorporated some of his ideas in my lectures (although I expanded the 5-step process to 6 steps for the students). Well recommended.

  21. Current Network Security on Changes in the Network Security Model? · · Score: 1
    It sounds like you have a sensible perspective. References you might consult include:

    -Practical Unix and Internet Security, 3rd edition

    Building Internet Firewalls, 2nd edition.

    Securing Windows NT/2000 Servers for the Internet

  22. Re:A quick translation... on EU Parliament Approves Software Patents · · Score: 1

    The directive as passed sounds quite reasonable. It attempts to block patents on algorithms and business methods, which have been the most obnoxious problems with software patents in the US. We'll see how it is enforced.

  23. Re:It's true! on The Origin of Murphy's Law · · Score: 2, Informative

    It was more a recognition that user interfaces should be designed to be used correctly. It was possible to do the fastenings both a right and a wrong way. At least the technician was consistent.

  24. Re:Direction for Java on Java vs .NET · · Score: 1

    I very well know. 8)

  25. Re:Portable? on Java vs .NET · · Score: 2, Interesting

    I know you're trying to be funny, but I mark my students' projects using my Mac dual G4. They were developed on PCs and *X boxen, but I run them on my own machine. If there are problems, we have a serious chat.

    I teach advanced object oriented design and security. It keeps food on the table.
