    What you meant, if you had turned on your brain, is that total downloads are the best available proxy on Firefox's broad-based mindshare. The other proxy available, user agent strings reported to web servers, is a better proxy on page views. But even this proxy is weak, since it fails to account for a wide range of caching effects. Anyone extrapolating short-term trends based on these metrics would be challenged to outperform fortune cookies.

  4. easy to quantify on 32-bit to 64-bit - Obsolesence Pains Again? · · Score: 2, Interesting


    This is just stupid. We exhausted the 16-bit address space in the era of the Osborne and Apple Poo. Ten years later we experienced a painful "transition" to 32 bits (after completely exhausting kludge space). The present situation is that high end machines can make good use of a 64-bit address space in kernel, but 99.9% of userland processes could remain 32-bit for a long time yet. The rare exceptions, such as database servers, those have been 64-bit clean since before the Alpha was first invented.

    Sure, let's compare a transition that took place ten years after the pain was universal to a transition that took place quietly ten years before most people realized that a 32-bit virtual address space could be exhausted with far less physical memory as a result of mechanisms such as nmap.

    This guy gets modded up for observing that AMD "doesn't have the volume". How much volume do you need to sell chips at $2650 a pop (Opteron 875)? Volume is a compensation for thin margins, a problem which AMD has been trying to put in their rear view mirror for a decade now. What AMD lacks, presently, is the volume to open the floodgates on their premium 90nm technology to the niggling unwashed masses. How much volume do you need to satisfy the market for people who really need this much performance? With dual core you can search Google in two tabs at once. The only sense in which AMD lacks volume is that it couldn't fill the crater if Intel suddenly imploded all at once. What AMD needs far more than volume is pricing power where the profits live. And for once they have that.

    This is a clear-cut example of feature creep. The old one-cylinder farm trackers would go forward and backward quite happily without changing gears, often with no operator input required. Also, there are plenty of cars out there that can do every legal speed in just one forward gear, or even cruise the autobahn in second gear if every passenger supplies their own iPod. The five speed transmission is an overstuffed contraption devised by a bunch of Swiss watchmakers trying to prove their continued relevance in the 20'th century. You can get most of the same effects by adjusting tire pressure, so I say we should stop making things more complicated than they need to be.

  7. exploits for dummies on Amit Singh's Challenge: Find a Decade-Old Bug · · Score: 4, Insightful

    The flaw used by panpipes has existed unnoticed for over a decade. If attackers were indeed actively looking for flaws all along, did they miss this one? If nobody was ever looking for any flaws, could there be more exploitable flaws lurking?

    The rest of the article is good fun, but this passage is a brain fart. There are millions of lines of source code in any modern operating system. Exploits don't sprout overnight like mana from heaven. The most useful skill for divining exploits is to notice the existence of edge cases in how various subsystems interact with one another. There is also the important case where "chance favors the prepared mind". This is where something funny happens as a result of an honest mistake, then the "prepared mind" notices (and pursues) the chance event's darker implications.

    Serious bugs that lurk for decades are hardly unknown. The ASN.1 bug springs to mind. It's hard to image a bug more widely deployed that escaped detection for such a long time. The question here is why, for such a long time, this simple flaw evaded interactions with dark energy. It's for precisely the same reason that experts rarely make the best testers. There are certain kinds of elementary programming mistakes that the "prepared mind" will habitually avoid. This distribution has a slim tail. If the minions of evil fail to stumble into any telltale clues after five years, chances are good it will remain hidden for a long time yet.

    This is in fact the same mistake that Kurweil makes in predicting the imminent singularity: that intellectual power is a fully ordered function, based on the premise that a really smart person can achieve any interesting result that any person much less smart can achieve. To put this in perspective, consider the recently discovered AKS primality test. This is what AKS achieved by some clever tricks using concepts of undergraduate algebra and a 15-year old theorem.

    I've been personally involved with all these technologies. In my shop, we run two OpenBSD firewalls, one on each available broadband service. Our automated build system is based on SCons, and our scripts make heavy use of rsync internally. Our embedded surveillance project runs Linux which we compile in a chroot build environment along the lines of scratchbox (but scratchbox didn't exist when we started). We also have an ARM7 microcontroller in our product running on top of the GNU tools compilation environment, with some structural similarities to eCos/Redboot. Have I missed anyone?

    I have a coworker here educated at the U. of Calgary (where I grew up myself) who knows (but does not enjoy) Theo through overlapping social circles. We had a short debate just a few weeks ago over a spicy Sichuan lunch special about where the boundaries between competence and personality belong. My coworker suggested "couldn't he accomplish as much without pissing people off?" I countered, "for someone with a knack for pissing people off, he retains some of the smartest out there within his circle. How does he do that?" There's a line I once read in Drucker that I've taken to heart "you're not in business to win friends". For me, the bottom line is that Theo delivers, and I admire the end results of his zealous rigour (regardless of where one might choose to draw the line between those qualities).

    Before I became involved in this shop, I studied computational linguistics, which brought me into contact with just about everything in the area from which rsync originated. I was depressed that Tridge had to lose the award he deserves as much (well, almost as much, although it pains me to say it).

    I've read all the benchmarks over the past year that show how OpenBSD is as slow as a senile dog. Whatever. For the purpose we employ those boxes, we've never had an iota of concern over performance level except for the negotiation phase on https. Guess what? Once Via/IBM finally coughs up the C7 Esther, OpenBSD running on a steroid enhanced 486 will crush the most expensive present day Pentium IV on our most essential performance metric.

    The odd thing about OpenBSD, which many people never manage to assimilate, is that you have to look at that project through a very narrow gun turret to realize just how much they accomplish by entirely ignoring the whingings from everyone else.

    It's an odd day in my personal universe to see RMS pat Theo on the back. I guess it takes one to know one after all.

I managed to bootstrap my FreeBSD server using PXEboot, but I had to liberally adapt the approaches I found because of the many changes in 5.x

    There's a lot of negativity floating around about FreeBSD 5.x lately. It seems they've put a lot of energy in breaking hard ground over the past two years. It remains to be seen whether lush vegetation will spout in future versions as they tune these improvements. I think in any project with sufficient ambition, there are times when things have to go sideways for a period of time.

    The fact that the "father" of the Tokamak declares that the program was never going to achieve its stated purpose proves exceedingly little. Perhaps the majority of speculative, high budget science is directed toward ancilliary ideas concerning applications the administration does not wish to openly discuss.

    I went through the SF airport in the early eighties and there was a grade A kook there handing out these "from another planet" booklets about the Tokamak program. They were about the size of a comic book but with glossy cover sheets, not quite a full magazine. Everything written there made my eyes bug out of my head, as if the author were six time zones and a dateline to the right of Ronald Reagan.

    On that same trip I met with a friend at Stanford who had recently attended a lecture by a speaker associated (perhaps tenuously) with one of the right wing think tanks that sprouted up like mushrooms in that era. This guy was smart according to my friend and in his speech he explained that the entire military build-up that was taking place at the time was a ploy to push Soviet Russia over the brink economically. That interpretation of the situation was not widely circulated at the time and IIRC it didn't hit the mainstream media until years later. Meanwhile, people were seriously debating whether Star Wars might possibly work, as if it mattered to the underlying objective.

    My view is that the MX missile system, the Star Wars program, the Space Shuttle, and maybe even Tokamak were all elements of a conscious effort on the part of American government to incite Russia to bankrupt itself. Let's not forget that the Shuttle was used to deploy military spy satellites. My opinion is that the shuttle would never have been built in its final form if rolling secret satellites out of the cargo bay was not on the drawing board.

    Let's suppose there were Russian scientists sitting around sharing the realization that "that American Tokamak program which is devouring so much of their funds is never going to achieve the public goals they put forward to the American people". The second Russian would have chimed in "and what else can you tell me about the price of tea in China?" No one would have sat there and said "I guess that about wraps it up for fusion power".

    If someone wished to advance the position that while large amounts of money have been spent in programs of fusion research, it is not clear for political reasons how much of this money has been directed toward the goal of producing a viable reactor, then it might be interesting to include a link to the disavowal of one of the key Tokamak participants.

    There might be other ways to achieve fusion. The US government chose to invest in an approach that involved big ass magnets, plasma confinement systems, and laser ignition systems rather than racks of beakerware stuffed with palladium electrodes. What a huge surprise.

    Given that Tokamak served as a political pawn in the final chapter of the cold war it's amazingly disingenuous to pluck any primary document out of its original context.

    Another brilliant poster noted that if you put a sufficiently bad driver into any car no matter how good, the result will suck. Excellent deduction, Sherlock.

    Let's say the F1 tour consists of a pool of twenty top drivers and twenty top cars. The drivers and cars will be randomly paired up. You have the option to bet on the race, but you can only bet on the driver, or the car, BEFORE you know how the random pairings are made.

    Are you going to plunk you money down on the car or the driver? At this point in F1 the consensus seems to be that voting on the car is the better option.

    This is a somewhat stupid exercise in any case. The third term is how well the driver fits the car, and this is largely a function of chemistry between the driver and his crew. The talented clutch monkeys who contribute toward bad chemistry end up piloting a poorly tuned ride, or they don't trust the car 100% in every situation so they're afraid to leave everything the car can do out on the track (er, I mean metaphorically).

    Then it gets even more complicated because a driver with good chemistry in an astrobucks team concept might suck in a financially constrained environment, and vv.

    Now that I think about it, this whole thread is silly (duh, like I didn't know that). We should stop talking about F1 and start reading Ken Dryden's book (from ages past) about the difference between a "good good team goaltender" and a "good bad team goaltender". The role of the "good good" goaltender is to not make mistakes so his team can go out and win it on talent up front. The "good bad" goaltender is expected to take chances and stand on his head so that his crappy teammates have a chance to win on a flukely goal or two.
