Comment Good and evil (Score 2) 37

This is great news for disabled people. Exoskeletons do more than the obvious: They give the wearer, being able to stand and walk again, more self-confidence, .

My second thought however reveals my evil side:
Imagine this thing has wireless access. If so, it can be hacked.
Now picture some guy walking along a busy street with an exoskeleton, and me in a cafe nearby, seemingly playing "Frogger" on my laptop...

Comment Try a different approach. (Score 1) 165

As many have pointed out, you won't find a 3d-printer with the necessary precision.
Do what I did as a kid:
Make your custom part - I did it with plain old ABS and wood (without a printer, obviously) - and spare holes for the original LEGO parts.
Then you place your "connection" parts on a Lego board, put glue in your custom part, fix it on your connection pieces (waiting on the board) and done.
This will give you the precision for distances many pins apart if needed.
Nowadays use any decent 3D printer for your custom part and then do the same.

This story was on the front-page yesterday, do you guys not even TRY to keep track of this shit?

No, they don't.
Here's a typical working day of slashdot "editors":

Browsing the submissions: 3 hours.
Clicking on links provided with the submissions: 2 hours.
Trying to find the most misleading headlines for a story: 2 hours
Finding the most misleading quote in one of the related articles: 3 hours
Thinking of a clever remark to add to the quotes and fail: 5 hours

Hey, and even slashdot editors need to eat, drink and sleep, so there's no time to check what was posted yesterday.

Uh, we knew 5000 years ago the Earth was round. You think the Egyptians were morons?

That reminds me of a school project I was involved*:
Two classes of different schools went out on the same day, hundreds of miles apart but on the same geographic length, placed a rod vertically on the ground and measured the angles of the resulting shadows at noon.
Given the distance between the two points (via google earth) and using a bit of (school-) geometry they then could calculate earth's circumference.
Considered earth's "potatoness" the results were not bad at all.
And that's precisely what they did a few thousand years ago.

*) I provided one of the rods, heh.

[...] and I think that's going to send a lot of geophysicists back to the drawing board.

And they will love it, any (true) scientist like facts or even hints that question current theories.
I bet some of them started already with a huge grin on their face.

Comment "Unpowered" Energy ;) (Score 0) 128

This must be some new kind of energy ...
Every system you want to gain energy from has to be loaded with energy first. Both isn't possible without losing energy, at least in our universe which means any additional device on the human body makes the body lose more energy.

And probably completely unrelated:
The original article appeared on Nature on April 1st.
