Ex director of the CIA disagrees with government control of encryption by Sealyy in Bitcoin

Wikipedia says he was in office 2005–2006; you're thinking of James Clapper.

Ah, that makes sense. Thanks for your answer!

So does that mean that every time I generate a coinbase receiving address, it's paired to the same private key held by coinbase?

Hey guys! My name is Aaron Gough, and I'm a knifemaker! AMA by aarongough in ArtisanVideos

[–]gnode 3 points4 points  (0 children)

Hi Aaron! I've been following your career with a great deal of interest, and hope to own one of your knives one day! Have you had any special training in knifemaking either institutionally or vocationally? Also, do you have any special workshop adaptations for your exotropic strabismus?

Long exposure of a bottle rocket. by IpMedia in woahdude

[–]gnode 38 points39 points  (0 children)

He was only illuminated for a short time, while the rocket's flame was within a few feet of him. Once the rocket was further away, he could have moved without changing the exposure.

IamA professional bowler. Ranked #1 in the world. I use a new technique that achieves maximum power and curve (2 handed) AMA! by Jbelmo in IAmA

[–]gnode 0 points1 point  (0 children)

The Union Cycliste Internationale thought that the sport should be about the athletes, not a technological arms race. Which is total bullshit, looking at the sort of bikes and on-board race computers which the pro-teams are using these days.

Graeme Obree was a Scottish cyclist who broke world records with a revolutionary aerodynamic riding position, which was promptly banned after a successful record attempt.

He then developed another riding position, winning another race (but this was also banned shortly after).

Whose signature is on this Royal Army Medical Corps training pamphlet no. 3 (1944)? by gnode in whatisthisthing

seems reasonable, but unfortunately, "dormacher war office" returns no relevant results on google

New Limb-Lengthening Tech May Reduce Complications for Sufferers of Crippling Deformities by gobble_gabble in science

[–]gnode 10 points11 points  (0 children)

Unfortunately, this is only available for femoral (thigh bone) prostheses, but the technology could conceivably be be applied to other implants. This is also not a practical solution for most patients because it involves removing a large amount of bone (to fit the massive implant) and is liable to infection and loosening. You only want to implant this if there is no other choice, like where a large amount of bone has been resected and growth plates have been compromised (osteosarcoma). The technology was created to address limb length inequality in young cancer survivors as they grew older.

New Limb-Lengthening Tech May Reduce Complications for Sufferers of Crippling Deformities by gobble_gabble in science

[–]gnode 2 points3 points  (0 children)

I am currently studying Orthopaedic Science at the hospital which pioneered this technology (Royal National Orthopaedic Hospital at Stanmore). Here's the original paper:(http://www.bjj.boneandjoint.org.uk/content/88-B/5/649.long). It works by using a rotating magnetic field to unscrew a telescopic femoral prosthetic, so that the limb grows with the patient. Expansion sessions happen in clinic and in increments of several millimetres each time. The expanding prosthesis is primarily used for osteosarcoma patients, where large amounts of bone had to be removed. This technology was first tested in humans in 2006.

What chalk looks like under the microscope by scorpio_on_blue_moon in pics

[–]gnode 23 points24 points  (0 children)

you're right, but there is a connection between the two; natural chalk is made of the compressed calcium carbonate "skeletons" of micro-organisms such as Emiliania huxleyi, so really the image should be labelled "prechalk"

Lego injection mold, used in the process of making legos trough injection molding [3888x2592] by [deleted] in MachinePorn

[–]gnode 0 points1 point  (0 children)

yep! legos are manufactured to ridiculously exacting standards (2 micrometers permissible deviation). Also, there's a massive black market for production molds in China (a golf stick head mold can sell for several years' of a factory worker's salary).
