World Solar Challenge To Start In Less Than Two Weeks

Cap'nPedro Re:Nice, put unobtainable (26 comments)

$10,000 will just about cover the cost of your solar panels, good luck also getting chassis, aero shell, batteries, MPPTs, wheels/tires, etc. etc. etc. for that money.

Ask Slashdot: What Magazines Do You Still Read?

Cap'nPedro Re:Scifi/Technical (363 comments)

There was a $12 (ish) surcharge to get IEEE Spectrum as a print edition instead of digital so I opted for that to get an extra tangible benefit out of my membership. I don't value digital media, possibly due to a lifetime of piracy.

Mosquitos Have Little Trouble Flying in the Rain

Cap'nPedro Re:Impact energy not the same for small objects (186 comments)

I had a quick look through some journals and this is the closest thing I could find:
Mating Behavior as a Possible Cause of Bat Fatalities at Wind Turbines, Paul M. Cryan, The Journal of Wildlife Management, Vol. 72, No. 3 (Apr., 2008), pp. 845-849, Allen Press
Article Stable URL:

Bats are killed by wind turbines in North America and Europe in large numbers, yet a satisfactory explanation for this phenomenon remains elusive. Most bat fatalities at turbines thus far occur during late summer and autumn and involve species that roost in trees. In this commentary I draw on existing literature to illustrate how previous behavioral observations of the affected species might help explain these fatalities. I hypothesize that tree bats collide with turbines while engaging in mating behaviors that center on the tallest trees in a landscape, and that such behaviors stem from 2 different mating systems (resource defense polygyny and lekking). Bats use vision to move across landscapes and might react to the visual stimulus of turbines as they do to tall trees. This scenario has serious conservation and management implications. If mating bats are drawn to turbines, wind energy facilities may act as population sinks and risk may be hard to assess before turbines are built. Researchers could observe bat behavior and experimentally manipulate trees, turbines, or other tall structures to test the hypothesis that tree bats mate at the tallest trees. If this hypothesis is supported, management actions aimed at decreasing the attractiveness of turbines to tree bats may help alleviate the problem.

The Mating System of Tadarida brasiliensis (Chiroptera: Molossidae) in a Large Highway Bridge Colony, Annika T. H. Keeley and Brian W. Keeley, Journal of Mammalogy , Vol. 85, No. 1 (Feb., 2004), pp. 113-119, American Society of Mammalogists
Article Stable URL:

Focal animal sampling at a highway bridge revealed an aggressive and a passive male copulation strategy that may function as adaptations to different roost conditions. During aggressive copulation, the male separates a female from a roost cluster and restricts her movements during mating while he emits characteristic calls. During passive copulation, the male moves very slowly onto a female that roosts in a dense cluster. Passive copulations occur without resistance from the female and without male vocalizations. Both males and females mate with multiple partners, suggesting that mating is promiscuous.

I'm an electronic engineering student, not a biologist, so someone else may find better information!

Mozilla Foundation Releases Firefox 7

Cap'nPedro Re:Fail (452 comments)

Slightly off-topic: I don't want to move away from FF 3.6.x... I don't like Chrome's UI, and I don't like how FF is just copying it. I hope somebody forks FF 3.6 to give it support for HTML5. I might if I ever find the time.

Computers Could Grade Essay Tests Better Than Profs

Cap'nPedro Re:Play favorites? I believe it (323 comments)

The first test was six definitions and one problem involving steam. All but one person in the class used the Ideal Gas Law to solve it. And he marked us all wrong, because -he- hadn't taught us the Ideal Gas Law yet. (Never mind that you had to have two semesters of Physics to take Thermo...)

Maybe I'm misunderstanding you here... But you were wrong. Steam can not be approximated to an ideal gas. You need to use your equations of state/heat capacity equations with a set of steam tables.

Detroit Maker Faire Was Kinda Awesome

Cap'nPedro Re:Those extrusion 3D printers are crap (138 comments)

The DLP is so much easier to build, the results are so much better and it prints so much faster that I wonder why so many people are still working on FDM.

The cost of the substrate material. Volume for volume, ABS is so much more cheaper than the light-curing resins needed for DLP.

Tens of Thousands Flee From BT and Virgin

Cap'nPedro Re:People seem confused about Virgin, let me clari (258 comments)

You forgot that after using the service at full speed for more than 45 minutes (I was on the M package), you go over your download quota and are throttled to 25% speed for five hours. I've just moved and instead of Virgin 10Mbit cable I'm on Sky DSL. I get 9Mbit max down, but my average speed is much higher than 2.5Mbit. I'd get fibre if it were available, but my money will not go into VM's pockets again - this older, "inferior" DSL technology gives me a better experience because of the lack of VM's shitty traffic management policies.

How Education Is Changing Thanks To Khan Academy

Cap'nPedro Re:School bus (240 comments)

In the UK there aren't generally school buses for college (age 16 to 18), I used public transport (service buses) or cycled. Through secondary school (age 11 to 16) there were school-buses which would leave immediately after lessons finished however a mini-bus occasionally took people home doing after school activities. If that wasn't available you could either use public transport or do as I did and walk home (I only lived 5 miles from my secondary school).

How Education Is Changing Thanks To Khan Academy

Cap'nPedro Re:Students without broadband (240 comments)

Wikipedia tells me that "twelfth grade (12) [is] for 16–19-year-olds". When I was 16 and in college I was using the college library every day. I think that an effective education must involve independent learning, which will often involve a library. Younger students can't be expected to be learning independently, but once a student is 15 or 16, they should be in the library most days anyway.

A Closer Look At Immersion Cooling For the Data Center

Cap'nPedro Re:It certainly looks cool... (213 comments)

I have to wonder at their claim that it works well with standard OEM gear. Even most cheap consumer shit monitors the speed of at least the CPU fan and tends to freak out if a fan that is supposed to be there is either absent or performing substantially below expected speed

Enter the BIOS (hit DEL during Power On Self Test), go into the Power or PC Health (depending on what BIOS you have). Alter the value of CPU FAN to "Not Monitored" or "Ignored". Hit F10 (or whatever yor key is) to save settings and reboot.

SpeedFan (etc) will still give you a speed readout if a fan is connected, but your BIOS won't complain if one isn't.

This procedure should be similar for UEFI based systems.

30 Years To Clean Up Fukushima Dai-Ichi

Cap'nPedro Re:Megalitres? wtf? (342 comments)

9.5ML is an SI unit. The 55 kilotons should be expressed as 55ML (using water's density=1000 kg/m^3). So we can see at a glance that they need 6 tankers at the moment.

We avoid exponents this way. Or the short scale/long scale "billion issue".

It's and it resolves just fine for me on VM Cable (M) in NE England.

Does it really matter if they provide a crippled router? It's probably a piece of shit anyway; get something you can flash DD-WRT or Tomato onto.
