  1. Re:There's still a question of shares on Has World Oil Production Passed Its Peak? · · Score: 2, Insightful

    I use energy efficient lightbulbs.

    Do you know why they are 20 times more expensive than normal bulbs? Because they take approximately 20 times more resources to make (the lighting field is highly competitive, so the cost to you basically reflects the cost to manufacture them). So if you don't save more than the $10 extra to manufacture one energy efficient bulb, over its lifetime, in saved electricity, then you have done more harm than good.

    I bought a whole bunch of energy efficient bulbs. Most of them died within a year because they don't like dirty electricity and being cycled rapidly -- shorter than the average lifetime I get out of normal bulbs (despite the marketing blurb explaining that they last 8 times longer). The only energy efficient bulbs I have retained are the ones in the living/lounge room -- ie, the ones that are on for a substantial part of the day and are kept on for hours at a time without being cycled, and if they last 1 year, then I have likely saved >$10 in electricity, hence they have acted as a net energy saving.

    Unfortunately, so much of the stuff that uneducated environmentalists (it /is/ actually possible to be an educated environmentalist, you know, and I attempt to be one) and politicians come up with are really bad for the environment. Obtaining alcohol from corn/cane sugar (never understood why Americans love getting their sugar from corn, blech!) costs far more in energy to run the harvesting/transport/refining equipment than you get out of the alcohol in the end.

    If only people that had an actual influence on these things (politicians, businesses) performed triple-bottom-line analysis; unfortunately, the only people that do this currently are people who don't have to answer to share holders.

    I recycle.

    Again, a lot of energy. Is it really so hard these days to simply limit your consumption in the first place? Heck, I'm regretting that I may have to soon replace my 5 year old laptop, because even fvwm is getting too bloated.

    Anyway, I really ought to go ride home. I feel guilty now for getting a bike with carbon forks.

  2. Re:Solaris Vs Linux? on Solaris 10 to be Open Source · · Score: 1

    I'm not actually sure what SPARC hardware is good for these days. Every time I benchmark something, it loses. Granted, our best SPARC machine is an 8-way UltraSPARC-III 1.2 GHz. So maybe a faster SPARC chip might keep up with PowerPC and Intel a little better.

    I completed some benchmarking of some MPI parallised Tree-SPH code recently, and found that our Linux cluster with 2.6GHz machines was dead slow. 3 or 4 year old Alpha ES40's with 1GHz clocks and 8 times the cache per processor were 4 times faster. Hardly suprising (well, the scale of the difference was), because SPH codes need to lots of scattered memory accesses.

    The only thing that came close to the alphas were the new 2Ghz opterons I can use. They basically performed the same. They only have twice the cache of the P4s, but on the other hand, they don't have a brain-dead memory architecture (for instance, I found our dual CPUs were useless, the code was completely memory bandwidth saturated, and the second CPU added *nothing* to the performance - ie, for my code, our cluster has 90 entirely wasted CPUs. Naturally, this has bad implications for our scheduler - other peoples unrelated jobs are going to affect mine, and vice versa. The opterons, of course, have a memory bus coming out of each CPU.)

    Pretty simple at Swinburne (down right now for a major machine room upgrade of the electricity supply and UPS). The switch automatically detects the presence of a virus infected computer, and shuts off the port.

  4. Re:What?? on Who's Blocking Verified E-Voting? · · Score: 1

    The true solution is the simplest. Go back to paper ballots. What is your vote? Whatever you marked on the paper with a pen. No chance of anything changing your vote. Count the ballots by hand, with an observer from each party watching every vote get counted. No chance to drop any votes to swing a close result. Isn't this the true geek way? Ultimate transparency? Many eyeballs making the problem shallow?

    Every time I see the way Americans vote, and how they choose the most complicated system, I laugh.

    In Australia, we hand count the results. It takes about 4 hours to get the final result (although a couple of days, if it a very close election, because you have to wait for postal votes to come in, if they could add up to change the results), sometimes less if the election is not close (you only have to count until you find a winner; the rest are only needed to find out exactly how much they won by).

    Why don't Americans just hire 10 times the people to count everything, since you have 10 times the population? You ought to have 10 times the money to hold elections, so this ought not be a problem for wages. Voting is incredibly simple - just mark your ballot and put it in the box.

    Why do you have to take the most complcated broken system? No punch cards, no lining up holes with names, just a pen and paper. Really *really* amazingly simple!

    (don't get me started on your broken "first past the post" voting method where if you have a few closely aligned but different parties, they will always lose relative to the larger more united party, even if the many smaller parties add up to even larger)

    I'm a little surprised that this has never happened before, as they often have featured logos. I guess those fractals must have just looked too alluring, and people had to see them.

    Another problem is that Paul has 2GB of graphics and movies on his page. Those fractal pages are the tip of the iceberg - Paul's pages being one of the authorative sources for a lot of graphics related things. We have banned people by IP before, because they run a wget session and try to slurp the whole fricking 2GB down the line.

    So when google directs a large amount of people to a page that turns out to be interesting, and so a lot of those people end up clicking their way around a site, then the problem starts. I doubt this would have happened to anyone who's page consisted entirely of a few pretty fractals, and that's it.

The poor server is a lowly alpha 500AU (IIRC, my ssh session is tailing the logs, but it seems I can't get bash swapped back in to run a uname -a). Our connections are fine from the department to the outside world and vice-versa.

    The trouble is, this is a webserver for an astronomy and supercomputing department. Paul Bourke's page is from his research - graphics and visualisation. He was intending google to index it - it is our most popular set of pages, and is one of the authorative sources on a lot of things to do with graphics. We just weren't expecting google to link to it from their little graphic thingy. We don't want to ban google from indexing the pages, because that renders the research pointless if no-one can use it.

    FYI, the server transferred 30GB in the first day of being hit by the google effect. I transferred 30GB in one day from one of the other supercomputing centres in Victoria, but this was just two processes. The poor webserver is struggling under the load of 150 apache instances right now.

  8. Re:what's the use? on Multiple Monitors Increase Productivity · · Score: 1

    I have six virtual desktops on my current single-monitor setup. I normally have at least four in use, and frequently use all six. If I had to group these on to physical monitors I would need to move to a bigger room, and would probably end up with whiplash.

    I have 2 virtual desktops, (one "theory", and one "play"), and each of those is divided into a 6x4 virtual pages. These are usually full of junk, but I have sort of worked out that a particular program always goes on a particular page, (and xemacs takes up 8 different pages at a time, with position in the desktop dependant on which program is in the buffer).

    I have used multiple monitor systems before (and have a laptop next to me currently, and linked by using debian's x2x - which is just the r0x0rs), and love them to death. The control computer at ATNF is a 4 headed beast, unfortunately on win NT (that crashes once a week) - the left monitor has a browser, usually open to the BOM weather page, the other 3 have about 5 different control panels and diagnostic plots.

    Now, here comes the question. How does one use both a dual headed setup with a pager? I use fvwm2, and would never ever ever get rid of FvwmPager. But can it integrate with a xinerama setup? Is each of the virtual pages twice the normal size, so one virtual page spans across both monitors? Or do you have one pager per monitor?

    I read something in the docs that seemed only relevant where you are not running xinerma, and instead have two separate displays - :0.0 and :0.1. I also thought I read somewhere that fvwm2 was actually xinerama aware, or being worked on.

    Anyone know?

    Of course, this is a moot point, because I have a 19" LCD, and there is no way in heck the department are going to buy me another flat panel, no matter what size it is (and there is not enough room on my desk for a CRT)

    You missed the point. While wiping /home would be 'unfortunate' for you, it reduces the virus' spread.

    Since this article is about the spread of virii on popular systems, let's concider for the moment how most people use computers. Most people have one computer to themselves. They will set up an account for themselves, and probably their entire family uses that one account. They store a year's worth of data on it, and then a virus comes along. Now, you are saying, well, it's only limited to the one account. For most people, this is everything. The OS can be reinstalled. Everything is reproducable, *except* for the data in the user's home directory. And this is precisely the stuff the virii will delete.

    Now, concider the action of spreading. What about being an unpriveleged user stops the spreading of the virii? Blocking of ports below 1024? Doesn't affect sending an email to everyone on the address book.

    The guy also talks about how the lack of a dominant monoculture means virii will never spread under linux (despite the argument being that when Linux is dominant, virii still won't spread). Intel vs AMD vs alpha vs MIPS, whether the user uses mozilla or kmail. Well, condider that when Linux is popular, most people will settle on the program that gets set up by default on the default desktop, using the most popular distribution. We don't see a monoculture *today*, because most Linux users use what they prefer, not what comes by default. Oh, and of course, on an Intel box.

    The galaxies group found their imaging software was not as quick (I don't know by how much) than on a dual 2.8GHz workstation.
