Comment: He takes off using the prosthetic leg... (Score 4, Informative) 175

If you watch the jump carefully you'll notice that he takes off (launches) from the prosthetic leg. I wouldn't be complaining too much if he took off from his real leg.

Look at the kangaroo, a kangaroo has a very long Achilles tendon. This allows them to be very efficient in jumping buy storing up so much energy when it stretches out like a rubber band enabling them to jump very far with very little effort. Humans on the other hand, have very short achilles tendons and therefore do not have this mechanical advantage.

When landing, the impact force and weight of the this guy is absorbed by active elastic stretch of the prosthetic. When he jumps, the weight is accelerated by a recoil force due to elastic recoil of the the prosthetic. This recoil force is much greater than that of what our our achilles tendon plus the active contraction of our calf muscle can do.

This guy has the equivilant of a 15inch long achilles tendon. As if you look at the video when he actually makes the jump, you'll see the prosthetic "foot" is bent 90 degrees from it's normal angle. The human achilles tendon is a) not 15in long and b) doesn't bend 90 degrees.

As a side note, I would assume there is no "fatigue" or decrease in "springiness" of the prosthetic between his first, second and third jumps. He could always show up to an event with a brand new prosthetic.

He's cheating.

In the old days (1980s), my laptop would go weeks without a battery charge.

I guess if you didn't turn it on, and I'm calling BS.

As someone that worked on the Original Thinkpads (IBM 755cx and the 701C (butterfly), I guarantee you that no laptop in the 1980s could run for weeks without a charge, unless you claimed systems that were more calculator than laptop (intel 386/486 type CPU).

Note that the 755CX sold for about $6000 back then.

Two things stand out:

How do you fit it into your front pocket? Maybe if you were overalls it'll fit into that massive chest pocket, but for regular jeans/slacks/pants, I doubt it.

Sharp corners... if it already barely fits in your pocket sharp corners are going to make it even harder to get out.

Unfortunately thanks to Netflix and Amazon, I'm barely staying within my usage cap with Comcast as it is.

What the hell are you downloading? Raw uncompressed blu-ray images? According to Netflix's usage page, the highest quality streams use HD: 3 GB per hour, 3D: 4.7 GB per hour, Ultra HD 4K: 7 GB per hour.

For a HD stream, it would take you over 80 hours to reach 250GB. 40, 2hr HD movies. Wow. Just Wow. The average American watches 2.8hrs of TV per day. If you download 100% of only HD content from Amazon/Netflix every month you'll be about at the 80+hrs / month of usage. Still a lot of downloading, given that you can't watch live events (sports/news broadcasts). Btw, even the World Cup isn't broadcast in 1080p like on broadcast/cable TV.

The current caps are from 250GB to 350GB depending on your service area. In fact, if you look at your data usage, you'll notice that they've suspended the 250GB cap enforcement.

You do realize that you fall into the .000001% of consumers who should be on a business plan if they want to download 50TB/month.

Remember no business caters to the .0000001% of consumers regardless of their business. You should vote with your dollars, find a provider that will give you unlimited usage with higher bandwidth. I'm sure there's plenty of ISPs that would be willing to drop an OC48 (2.4Gb) into your house for a quite a few grand a month. Or a Comcast business solution that has no cap.

Surely a 150Mbdown 20Mb up with no caps for $250/month is enough for you and your entire family to watch HDs every minute of every day until your eyeballs rot. Just think, with 150Mb/s down you could consume about 65GB/hr, or 20 HD movies per hour 24hrs per day, 7 days per week...

Right tool for the right job. Obviously you want Commercial Services at Residential Pricing and you don't meet the requirements of the typical Residential user, so switch to Commercial Services and be happy.

Damn I hated working with [SGI] UNIX. You couldn't wipe your ass without them wanting to charge you for it.

Guess you never worked with Banyan Vines... you couldn't do anything without a hardware dongle attached to the parallel port on the back. If you wanted to enable multiple features, you daisy chained multiple dongles off each other. I recall seeing servers with 5-6 dongles hanging off the same parallel port like some sort of unicorn horn.

Don't feed the trolls.

I used AWS for a few projects for my research. I would upload a data set to AWS run the MapReduce jobs and then analyze the output in AWS. Once complete, I'd download the results and shutdown the whole environment. I could programatically spin up the whole environment in about an hour or so.

Whole thing cost me about $350.
