  3. Re:Are they messing with units again? on New Solar Panel Technology Gaining Momentum · · Score: 2, Insightful

    This has got to be the first reasonable usage of the unit megawatts per year. TFA says that they can build a factory to produce "100 megawatts of solar panels a year".

    The astute among us at slashdot always say, "Megawatts per year, eh? Does that mean they increase electric power production by 100 megawatts every year? Duh."

    Well, in this case, yes. Yes it does.

  5. Filter out the laser light? on Chinese Lasers Blind US Satelites · · Score: 1

    For optical satellites, it should be possible to use filters to prevent the light from the (frickin') laser from ever hitting the light detectors that digitize images on the satellites.

    Obviously, if there are no filters on the existing satellites, they will have to launch some new ones. I envision a "colour wheel" of filters that are optimized for known laser frequencies, plus maybe another wheel of filters with broader notches to deal with the unexpected.

  6. Re:Not so bleak on Browser Vulnerability Study Unkind to Firefox · · Score: 1

    One reason why Firefox is not targetted is that it is not as commonly used, so malware has less chance of survival and distribution in a smaller population.

    Another reason is that some users do not run Windows, which makes vulnerabilities harder to exploit. Though possible, it's hard to infect a Mac, Linux, HP, Solaris, AIX, or BSD box with a virus or trojan designed to infect Windows XP. Although the installed base of Firefox may rise over time, this heterogeneity will continue to diminish the incentive that malware authors have to attack Firefox.

    The third reason Firefox gets attacked less is the short turnaround time for patches and fixes, as noted in the FA.

    The only real reason to attack Firefox is that it's new(er), and under active development. This reason should fade as the software becomes more mature. Time will tell.

    It's funny, Internet Explorer is the exact opposite on these four points: it's installed base is large, it's operating environment is homogeneous, it takes a long time for problems to be patched, and it's more mature.

  7. Re:(sigh) on Voting Machines Wreak Havoc in Maryland Elections · · Score: 1

    Here is a link to the number of votes cast in every federal election in Canada since confederation: http://www.elections.ca/content.asp?section=pas&do cument=turnout&lang=e&textonly=false.

    In June, 2004, Canadians cast 13,683,570 ballots. Every one of them was counted by two people in a locked room, usually a gymnasium or a church basement. They each put their hands on the ballot, looked at the ballot, and said aloud which candidate the voter cast his ballot for. Another person kept a tally. They were volunteers. Paid public service workers oversaw the counting, as did scrutineers designated by candidates running in the election. After a ballot box's ballots were counted, the two tallys were compared. If the counts did not agree, another team recounted the ballots from that box. I've done this. It feels good to do it.

    Within a few seats in the House of Commons (there are 308), I knew the results before I went to bed. Because the country spans many time zones, people in Newfoundland had to wait until they got up in the morning.

    The way you ran an election in your high school scales up to run an election for an entire nation. So scale it up.

  9. Re:introducing the station to debris on Inflatable Private Space Station Launched · · Score: 2, Insightful

    You are correct that the magnitude of the rotation vector is the same for any two circular orbits of the same diameter, however there are two things that you have not considered:

    1) Orbits are elliptical, so orbiters can collide at non-zero relative speeds.

    2) The direction of the rotation vector need not be the same between any two orbits. One orbit may be pole-to-pole, while another may track the equator. Or one may be a "left-hand" orbit around the equator, while another may be a "right-hand" orbit. The second case is the worst: the space junk could hit the station at a relative speed of twice the orbital speed of the station.

    All the comments on this post about designing the station to withstand the impact of any untracked space junk still applies, though.

  10. I switched because of it. on End of Win 98 Support May Boost Desktop Linux · · Score: 2, Insightful

    An anecdote does not make a case study, but I switched to Linux on the desktop because of the end of support for Windows 98.

    I've been using Linux for over a decade, but never as my desktop OS. I admit that I was well behind on software, still using Office 95, but the cheapest Dell with OS and Office 2K3 is about C$800, whereas the "guy-in-a-storefront-on-Kingsway" computer plus Ubuntu & OO.o is C$400. (I re-used the old monitor, though).

    I assume that most home users just pirate a copy of Windows and Office to keep costs down, but I wonder why. It's morally questionable, tortious, and unnecessary.

  12. Re:Wait a second... on Moon Mining Gets a Closer Look · · Score: 3, Interesting

    I have always wondered if it would be feasible to simulate Earth's gravity with a kind of large merry-go-round. Put apartments at the end of rotating arms, on hinges, and then spin it fast enough to make the vector sum of the moon's gravity and the centrifugal force in your rotating frame equal to 9.81 N/kg. The hinges at the top of the apartments would make the apartment always line up with the "gravity". You could spend all your non-working hours in a human-friendly force field. I wonder if the large (compared to Earth) delta between the force at your head and the force at your feet would cause an unsafe stretching of your spine.

    I disagree. I have interviewed a lot of people outside "standard" work hours. It's pretty common for employed people to want to be interviewed after work. 6:00 is the most popular, 7:00 is number two. I've never interviewed someone on the weekend, but I'd be willing to do it.

    Many development shops want to hire people who are already working, so anyone who asks for an after-hours interview time gets one. Not everybody requests one, and if you don't ask for it then you won't get it. I've never held it against an applicant, but I prefer the six o'clock time...

  25. Re:bad science = scam on Company Develops Microwave-powered Water Heater · · Score: 1

    Wahoo! Lets do the math:

    Low flow shower head @ 0.2 l/s
    Water specific heat 1000 J/K/l
    Heat water from 260K to 310K

    10,000 J/s = 0.2 l/s * 1000 J/K/l * (310K - 260K)

    So a 10KW heater will work for a low flow shower head. That's a pretty serious heater, but is it impossible?

    Suppose the whole population takes a 6 minute shower between 6 and 8. So about 5% of the population is taking a shower at any given time. I don't think ConEd could supply an extra 5GW (more than two hoover dams) of power to NYC for two hours every morning.
