  1. Re:First Post! on Detecting Spoofed MAC Addresses On 802.11 Nets · · Score: 2, Informative

    From the amount of the whitepaper I skimmed through, it looks like this could be used over copper, but the type of attack that it detects is rare or non-existant on copper because of the inherent difficulty of taking down a single client with DoS without taking down the entire network itself.

  2. Tubes, men, tubes... on U.S. Air Force Developing Microwave Weapon · · Score: 1

    What everyone forgets is that all these dictatorships use "old-school" (not really) tubes. Sure, EMP will destroy modern Western solid-state electronics, but keep in mind that most of Saddam's equipment (if he is intuitive) is most likely controlled by vacuum tubes, which are the least effected by EMP of any electronics. Russia and all the formerly USSR regimes use tons of equipment with not one transistor in them. In the case of nuclear blasts, the US infrastructure would be knocked out before theirs.

    That would be because the opposite is obvious. But let's say most people including you didn't know who Bush was, but because of certain circumstances (reading about his political stance and involvement etc) you correctly inferred that he was white, that would be mild insight, would it not? If you knew he was white, and you told others he is white, then it would be simply informative.

    Because it was insightful. Some people who are intuitive, even about things they aren't officially experts in.

    Most likely no one remotely understands the First Amendment. You get judges with conflicting interpretations, and judges handling the cases would be expected to understand it. But if they did understand it, there wouldn't be conflicting interpretations, would there? So therefore, anyone is justified in using some common sense in conjunction with the little they may know.

    You don't have to know very much about something to make an insightful observation. Insight is seeing things not obvious. If this person understood the amendment, it would not be insightful, but merely + 1, Informative. Anyway, this comment, as well as yours and its parent, is an opinion of each respective author. Feel free to disagree.

  7. Re:Confusion? on Microsoft Drops .NET Name For Next Windows Server · · Score: 1

    IANAexpert, but .net is a security and synchronization framework that applications can interface with to autoupdate for example. Different functions in the application can have separate methods of updating, and certain functions can only be accessed by users with specific rights. The original idea of Hailstorm was to provide web services where parts of the program would be stored locally, parts would run from a network drive, and parts would run from a web server. As well, hard disk storage can be abstracted to isolate programs from the rest of the computer. You can specifiy to which extent an application interacts with the operating system as a whole. Palladium is simply a hardware/software system for verifying and authorizing applications and data for use. An example of someone using .net is installing a program that can read and analyse any file on the computer, but through .net restrictions can only save to its allocated disk space fragment. as a matter of fact, when the program goes to save something, all it knows about is its home dir, but when it reads, it sees everything.

  8. Re:Windows also supports Viruses on XPde: Cloning the XP Interface · · Score: 1

    This is not a troll, nor it is intended to be flamebait. This is biased information based on my experience alone, consisting of gross generalizations and blatant opinion ;)

    If you are a reasonably current Slashdot-type, you will not get viruses on your Windows computer. Some security patches require deliberate visits to windowsupdate.microsoft.com because they aren't automatically installed, and some require being up-to-date on the latest News for Nerds and bugtraq, but as long as you ignore spam and run a reasonably new virus scanner, and dont open forwarded personal email, you will stay virus free.

    Four years and counting here, from win 98 to 2000 to XP, and only two viruses ever occured and by that time I had Anti Virus, which caught them. Plus, those two 'viruses' were actually trojans that I consciously downloaded over P2P thinking they were cracks for games. Don't trust small executables.

    I was running IIS when Code Red was around, but since I patched immediately with a patch from F-Prot, I remained untouched. Another thing I did was switch to Apache for Win32 :)

    Oh...another thing...any reasonably security-conscious /.-type would only use NT5 if they were to use Windows.

  9. Re:Time to ditch SMTP on ISP Chief on Spam · · Score: 1

    Okay sounds great! So the architecture is already there...just the addressing and filtering system would have to be implemented. I wasn't aware that the public/private keys worked both ways.

  10. Re:Time to ditch SMTP on ISP Chief on Spam · · Score: 1

    And I forgot to mention that primary filtering would be completely key-based (deny certain keys or deny all but allowed keys, etc). And addressing as well could be key-based, with a DNS-like naming extension for easy storage in the brain. Perhaps half of the key could belong to an ISP/email provider and half to the user, etc. At the client's end, the message would be converted into final text form and sorted into folders from there. Of course, if you had an opt-in filter, there would need to be a protocol for requesting acceptance etc.

  11. Re:Time to ditch SMTP on ISP Chief on Spam · · Score: 2, Interesting

    How about "reverse PGP authentication"? Where everyone can decrypt the payload with a public key, but only the real sender can encrypt it? The roles of the private/public keys would be reversed. Of course, inside the "encrypted" public message, conventional PGP could be used for security. The public authentication key would be bundled with the message so any server could validate it. As well, inside the authenticated message, before the payload, a special header would contain the public key as well, so servers could validate the sender more quickly by encypting only part of the message, matching the external pubkey to the internal pubkey; if they match, voila! Got that? :) Just a thought.

  12. Re:Except that some of these are already dead on Disruptive Technologies For Next 5 Years · · Score: 2, Informative

    I don't know if I am arguing with you or supporting you or what, but I believe there was an article a while back on slashdot that talked about technology that used optical fibre as the structural core for last-mile power cables. I thought it was neat and appeared to be doable because fibres are light and strong, and would have a dual purpose. As it stands, last mile power cables are currently made of a steel core wound with aluminum. Imagine the savings and benefits (granted, not for the steel companies) of using optical fibre as the core, or even using stronger composite fibres (think carbon fibre/nanotubes) as the structure mixed with optical fibre for data.

  23. Poor design... on Pipeline Mass Transit? · · Score: 1

    IANAEngineer, but I think they designed the doors wrong...everyone must note that doors on current pressurized fuselages (read: aircraft and spacecraft, even pressure tanks) open inward. This is because having doors close against the inside of the frame allows for inherent sealing and latching forces (due to internal pressure).

    As well, hatches in the walls of pressurized containers never have sharp corners, and they are fairly symmetrical. This is because corners and irregular edges are weak points in the structure. As well, the cuts in the fuselage wall should be as small as possible for strength.

    From the diagrams, I see that the doors in the concept are HUGE, IRREGULAR PLOYGONS, SHARP-EDGED, and OUTWARDS-OPENING. More realistically, the vehicle would have very little style; round windows (if at all - strobe issues), tube structure with hemispherical ends, and small, round or rounded-edged symmetrical doors.


    Anyway, that's my two cents.
  24. This technology does NOT use mud. The OLD tech did on High-Speed Data Transfer Over ... Mud · · Score: 3, Informative
    From what I read in the article, the heading for this article is inaccurate. The new technology uses a high speed digital cable embedded in the pipe wall to send data to the surface.
    To quote from the article:
    The key to the new system is a unique non-contacting coupler embedded in connections between 30-foot long sections of drill pipe. The coupler permits data to be sent across the connection and on through a high-speed cable attached to the inner pipe wall.

    For more than 60 years, engineers have struggled with the problem of a drill pipe connection, or "tool joint," that would stand up to the wear and tear of increasingly hostile downhole drilling conditions, yet provide reliable electrical connections every 30 feet over thousands of feet of pipe penetrating deep into some of nature's harshest environments.

    Largely because of the stumbling block, in the mid 1970s developers turned to a technology called "mud pulse telemetry." Mud pulse telemetry foregoes electrical connections and transmits data as pressure pulses through fluid circulated to clean the cuttings out of the wellbore.

    But the excruciatingly slow pace of mud pulse telemetry - 3 to 10 bits per second - often meant that data resolution was so poor that the driller could not make crucial decisions in real time. Often, time-consuming operations would be required to retrieve the downhole data or drilling would have to stop while other procedures were employed to confirm the low-resolution data pulsed to the surface

    If you installed a single massive (in the scientific sense) gyroscope on the train, with axis of rotation horizontal and lateral, and forward spin, the train would lean INTO the turn, whether the track banked or not. And it wouldn't FALL into the turn because the gyroscope in that config would seek a position with the net result of centripetal and gravitational acceleration vertical relative to the CAR.
