83-Year-Old Inventor Wins $40,000 3D Printing Competition

gurudyne Use a big hammer (146 comments)

I have designs for safety related equipment used by the industry for almost 20 years before I got around to completing a degree.

One of my favorite tests was to use a 220Kg hammer (on a pendulum)to smash the competitions stuff against an anvil. Then I made sure my stuff took at least twice as much swing to break, while have fewer, less expensive parts. Fail fast and often, then figure it out.

And those items are still used today.

Because I listened. Both to engineering instructors (with over 250 hour to graduate, I had a broad education) and to old BDIFFF (Been Doin' It For F*****g Forever) people. Hi, Jake!

I learned how to do for a dollar what any damn fool could do for two.

Does Open Source Software Cost Jobs?

gurudyne Re:Quote Investigator to the rescue! (530 comments)

No, but they both involved enormous government support.

Land giveaways for the railroads.

Fuel taxes for the highways

(And, some of the US Rte 1-101 highways were built by the WPA.)

New Rechargeable Battery Uses Water

gurudyne Re:Over time ... (179 comments)

Not if you do it at the outlet of a river to the sea, where the mixing has been happening for billions of years. I think life in that area has adapted by now.

Uh, you are looking through the telescope the wrong way. That flow you quoted is at the UPPER end. From the same site you linked to, the flow is 50 times greater at the Delta, where you find the OTHER side of the cell, salt water.

SFLC Wants To Avoid Death by Code

gurudyne Re:So what (247 comments)

I've tested medical device software and I had to sign my name on forms over 5K times for just one version. This was just for the behavior and appearance of the localized GUI, not the pure functionality. Each test was recorded via video. The 90GB of video, 4GB of datasets, and the 220 pounds (100kg) of signed test forms were shipped at the end of the 6 week series.

At the medical device customer's end, all of the tens of thousands pages of signed and initialed test forms were scanned and burned to disks. The plan to hang on to these for about a century.

Then, the forms are updated and reviewed, new languages and OS versions added and the cycle continues. Every step is reviewed and audited. We don't want the FDA asking 10 years from now if something was tested or considered for testing without giving defensible answers.

The folks testing the functionality of the software had close to 100K of tests for each version of device software. (Different vendor, so I am going by what the device company told me.)

We all reported to the same defect database, so we could be aware of progress and problems.

Long hours, fun times.

Solar Plane Completes 24-Hour Flight

gurudyne Re:Hybrid Planes (88 comments)

If solar cells were 100% efficient, they might be able to gather enough energy to power the entertainment electronics on commercial aircraft.

Yes, you have a steady supply of power but you would be lucky to gather one (1) kw per square meter on cells oriented 90 degrees to the Sun. Since that would probably not be optimally aligned to the flight direction, your collection would be less.

Robots To Clear the Baltic Seafloor of WW-II Mines

gurudyne Re:Mines that old really still dangerous? (286 comments)

Probably not saturated. You may be thinking of gunpowder. People are still getting killed with WW I buried mines and shells.

Quoting Wikipedia: "TNT neither absorbs nor dissolves in water, which allows it to be used effectively in wet environments."

Let's say that only one out of twenty still work. Do you feel lucky? Exciting times.

And just what kind of reefs grow in brackish waters that freeze over in the winter?

Certainly, there aren't any corals in the region, except for hotels.
