    Or the nachi/a worm which tried to remove msblast then download and install the patch for the hole from MS.

    It was a misguided attempt to stop msblast but it caused a lot of problems itself. We never had a problem with msblast but nachi essentially shut down a couple of our routers and cost us plenty in man-hours to clean up.

    I doubt that Dabber is the same deal though. If it were you would expect it to have an expiration date.

  9. Voluntary and Temporary on Privacy in the Woods? · · Score: 1

    Let those who want to be tracked have an ID tag. They can "check one out" and leave whatever identifying info they feel ok with. Ideally have it either only keep the last two checkpoints (so you can get last location and direction.) Regardless, have a return of the ID tag wipe all history. It will help prevent wild animals from tripping your sensors and let those who don't want to be found... not be. If you are worried about theft of the tags, require ID. If a person values their privacy more than the safety net of the tags they don't have to take one. On the surface, it seems like a bit of waste of money. If it prevents a helicopter and search and rescue crew from being dispatched though, I suppose it might pay for itself.

  12. Re:The question I always ask is on Programming As If Performance Mattered · · Score: 1
    The answer, I think, is "it depends." You need to know your data and how your code is going to be used. Here is a real example:

    Back around 1999, a coworker wrote a "round" routine for foxpro for dos. (Database language for those who have to ask.) It didn't round to the decimal, it rounded to the nearest 1/2, 1/4, 1/8, 1/16, etc.

    The way it did this was to build an array of every fractional value in decimal form, grab the decimal portion of the number, and then search the array for the nearest match.

    Even then, this could find the nearest 1/8th in just a small fraction of a second. But it fell down (miserably) if you were looking for the nearest 1/128th, or (since this WAS for database work) you were rounding values from a million records or so.

    The solution was to multiply the original number by the denominator (ie: x * 8), round to the nearst whole number and devide it back. So, the code ended up looking something like

    frac_round(num, frac) {
    return (ROUND(num*frac,0)/frac)
    }

    The point is that optimization, even then, wasn't neccessarily about squeezing every ounce of speed out of your hardware. It could be more about not doing stupid things in your code, especially if the "stupid" part was going to be run repeatedly during execution.

    Someone could have spent a day converting his slow round code to C or assembly and building a new function in a library to call from FoxPro. Not much payoff doing that though.

    You could even do the same thing for the code I listed, but then maintainability drops a ton. Now your DB programmers would need to know C or assembly to make changes. (Like adding a check to prevent a divide-by-zero fault?) As it was, it could process a million records in around 6 seconds if I remember... more than fast enough for the job it had to do. Why optimize any further?

    So, as much as possible, know how your code is likely going to be used and what the data is going to be. Look for choke points where optimization will acctually make a difference. And know when it's "good enough" vs when it's "as good as possible."

  13. Re:We live in interesting times.. on USENIX Responds to SCO; Fyodor Pulls NMap · · Score: 1
    I think that violation of the GPL would constitute removal of rights across all software licensed under it

    I sure hope the GPL isn't an all or nothing license. What if the GPL was found to be invalid with regards to a specific piece of software and a specific copyright holder (due to some action of the copyright holder?) Then the GPL is invalid for ALL software and would have to be replaced by a new license?

    Revoking all rights to GPLed software from SCO might give me a happy, warm, fuzzy feeling, but I don't really think it would be legal. At least not unless SCO actually violated the GPL with regards to nmap. I don't believe the terms of the GPL themselves allow you to restrict WHO can use the software as long as they follow the terms of the license.

    Even though SCO's statements are extremely hypocritical, I'm not sure that they constitute a violation of the GPL in general. The $699 license fee for the Linux kernel on the other hand... now THAT I think DOES violate the terms and I would love to see their right to distribute terminated until they change their action.

  14. Re:Question for the astronomers among us... on Newly Found Planetoid Possibly Larger than Quaoar · · Score: 1
    Ordinary asteroids in the inner solar system sometimes pass in front of weak background stars (occultations), which provides the opportunity to measure their diameters by timing the disappearence and reappearence of the star.
    I would think that the star would have to not only be observed at the right moment in time, but would have to be observed at significant magnification. You would need to be able to observe which direction the object was moving (with or oposite the earth's orbit and rotation) and how fast it was moving too. So frame-rate of the observation would play a part as well.

    Without that, how could you estimate size? Was it a 20 KM wide rock moving 400 KPH or a 1 KM wide rock moving 20 KPH? Ok, they may be moving way faster, but I'm sure you get my point.

    After you install MS Office, Windows loads big portions of it during Windows boot. So your initial boot takes longer, but then your Office apps launch quickly.

    I'll second that. We upgraded from MSO 97 to MSO 2000 on a bunch of PCs. After the upgrade, they things crawled and were not even usable for the main app they used to run... until a RAM upgrade.

    This was without MSO running and without the MSO quick-launcher starting. (Using the quick-launcher uses even MORE memory, but not using it does not prevent the pre-loading of all MSO components.)

    If they do try, they will fail miserably. The lack of scarcity of addresses will destroy any central control of the address space.

    However, lack of scarcity doesn't have a large affect in monopolistic situations. Charter Pipeline charges a monthly fee to provide you with a static IP address.

    On the surface, it might appear that this is due to scarcity, however, this really isn't the case. I am using an IP address at all times. Whether it is a dynamic address or a static one is really irrelevant... I'm still tying up one address. That means that not assigning me a static address really doesn't aleviate scarcity at all.

    In fact, if there is not an equivelent to NAT for IPv6 (I have no idea if there is or not) then it would be trivial for ISPs to charge per "device" connected to the Internet. While this isn't strictly a per-IP charge, it would be functionally equivelent.
