  1. Re:Too bad, another OSS jihad. on Another Step Towards BSD on the Desktop · · Score: 1

    Why must every good thing be turned into some kind of zealot-fest, rally to my agenda? How about we all simply enjoy the damn distro without trying to conquor this, push agenda that, holy-war upon everything that doesn't agree with me?

    After seeing the bearded hippies in the Linux World magazine ads, I must be of the opinion free Unix people are risk takers and think little of those who do not dabble in a few idiosynchratic computer procedures. Where else do we see such people? Motorcycle gangsters - and what do motorbike riders do? They ride headlong passing without heed, going somewhere faster than everyone else. A Unix user is born into a world that is just not quite at a somewhere but Unix is a pathway. Car drivers know that we'll all get there soon enough and could care less what a motorcycle can do. It just leaves me to wonder if the thrill of Unix is all in the ride.

    I appreciate Unix for its usefulness in massively parallel systems not to mention widespread scrutiny for security and logic flaws. Aside from this is Linux at all a launching pad for advanced operating system concepts rather than just a popular platform of mainstream goodies? Well, it's just the image of Linux as the domain of people who want more than what is available, not just an OS for people who can't afford Windows. There's a kinship and a resulting defensiveness and recklessness. But will something new develop?

  2. Re:current == power? on 19 million Amps · · Score: 1

    You're aware that power stations DO NOT OUTPUT AT 120V, right?

    Yes, and I know the law of conservation of energy. Granted some energy is lost in transmission and transformers and the like, but end users are most likely to consume power at 120V. So the current at the end will be quite high.

  3. Can We Reject the Null Hypothesis? on Hidden Black Holes Discovered · · Score: 1

    where obviously our laws of physics don't operate

    I don't see it is so obvious that the laws of physics are not usable to discuss the inside of a black hole. Newton's 3 laws (inertia, F = ma, and equal and opposite reaction), for instance - can you explain why they have no validity in a black hole? Well, to start with, there ought to be mass in the black hole due to the gravitational effects we feel on the outside, right?

    The laws of physics are the null hypothesis (statistics). Although we cannot accept the null hypothesis in our world, we don't reject it. I am not a black hole scientist, so I need to ask what evidence do we have to reject the laws of physics for the inside of a black hole?

    So Mr. Troll what do you have against foreigners?

    After 9/11 do you trust just anyone to fly?

    Anywho, if space is to be explored thoroughly it's going to be robots. If it isn't cosmic rays, it's the sheer time of travel that will kill a person.

    It's not a question of whether lives are at risk. With the death toll in Iraq around 1800, objectives will be set regardless of lives. The whole idea is to return the shuttle to the ground in one piece.

    It's not about the expense of the shuttle either. I've read that the shuttle is practically rebuilt after every flight, though with many components reused. The goal is to achieve reusability without such extensive overhaulage.

    all it *IS* is a test bed. Sadly instead of collecting valuable data *about the shuttle* on every single launch

    Scale versions of the shuttle should be launched frequently to learn more about things that can go wrong. Then questions like overheating wouldn't have to be answered on the real one.

  7. After 2003 EL61 on Hackers Forced Announcement of 10th Planet Find · · Score: 0

    Michael Brown was scooped once when 2003 EL61 was taken. The entire situation can be aptly described with "The plot thickens."

    Since Brown had already analyzed confirming evidence obtained in Jan. 2005 it's quite possible he was on the verge of announcing a new planet, complete with website, which someone may have quickly tried to peek into since Brown is quite famous in this area.

    In the age of the Internet you'd have to be a really patient person to sit on information from Jan to July, especially on something as controversial as Planet X. It makes you wonder if Prof. Brown has even bigger fish to fry.

    The Internet is not peer-reviewed publishing at its best, but rather the poor-man's way of gaining the attention of the world. However, the best information on the Internet tends to gain the most hits. Scientists shouldn't be too shy about posting their findings and bypassing the rigamorole of peer review. Web publishing also carries a high standard, especially because the presentation has to be accessible as in understandable and palatable by people outside a narrow field. Good web publishing might be characterized by its ability to persist on a server due to its popularity.

  8. Mod parent Interesting on An Inside Look at eBay Security · · Score: 1

    Computer security is essentially authentication so that the computer does what it is supposed to do, but the rest of the business activities, fraught with peril as they may be, are not the responsibility of people in charge of security. Users have to follow the rule of buyer beware.

    There are so many legal and policy matters, but auctions have been around for eons. The difficulty may be the sheer number of jurisdictions that eBay touches. This may bring about some uniformity in global law regarding certain paradigms of trade, particularly auctions.

    Now how easy is it to use eBay as a fence? If the buyer is just looking for a steal, then the thief has a source of cash. However, a victim can also search eBay for lost belongings - perhaps eBay can be the last resort for the lost and found!

    eBay is not just an anonymous cash transaction. A number of parties are involved, for shipping, payment, even the thief's ISP. A victim might request a trail for all items of type X sold. If theft is a big problem, all transactions of expensive items might be tracked with serial numbers.

    On July 27 being fairly warm and all the air conditioners running local power stations saw consumption over 20,000 MW.

    If outlet voltage is 120 V and P = VI, then
    I = 20 * 10^9 / 120 = 1.6 * 10^8 A >> 19 * 10^7.

    Granted not all users consume at 120 V if even as much as 10% of them used 120 V, the 120-V users will run almost 19 million amps.

  11. Planet Xena on Planet X Larger Than Pluto? · · Score: 1

    Planet X - Planet Xena

    X is the Roman Numeral for 10.

    Some more about X, now, as I have learned from late Saturday night radio mojo, "A View from Space". X is the mark of Cain. Has a prophesy come true regarding the coming of the one world government and their one world religion? Also noteworthy, the Spaceman believes that Christ was killed on a stick and the cross is the X used to mark Cain. The cross is how the X symbol is hidden. Are we in end times? Will Planet X be tossed into the inner solar system?

    If the end is coming, what would you do to take control of the situation or make life meaningful?

  15. Re:3 gbps? 3 gbps? Is that 375 MB/s? IDE/SATA does on Hitachi's 500GB SATA-II Reviewed · · Score: 1

    The cost/benefit point for processor caches is about 1MB or less. A 2MB cache CPU is maybe a percent or two faster than the same CPU with 1MB CPU

    Given the size of information being handled, 1 or 2 Mb is too small for cache to really make much difference. If you open a document or even a web page you can easily use more than 2 Mb RAM. The exe code can stay in cache - very helpful - but data is still slower. Cache >= 64 Mb would be really fast though clock speed will suffer.

    A compromise worth considering - more than one point of memory access so that multiple CPUs on one motherboard can work together quickly. I tried some high speed multitasking on a Pentium D and found that it was bottlenecked by the inability to load data from the memory as the separate cores try to work. High speed processors are mostly used to handle large volumes of information rather than arriving at one answer from a small amount of data.

    To protect yourself, make backups and check integrity of data constantly. One may consider the mean time between new vulnerabilities being discovered to be one day or less. Be ready to rebuild information from backups, which are troublesome to create but not as troublesome as the original entry of the information. Even a newly purchased replacement computer still has to be restored from backups, with no absolute guarantee of security.
