Software Error Caused Soyuz/Galileo Failure

mirix Re:Not A SW error! (153 comments)

Bingo. If someone sets a GPS to go to the wrong location, you don't say the GPS had a embedded software problem.

More like a failure to double check settings or something.

How Argonne National Lab Will Make Electric Cars Cheaper

mirix Re:Fire (143 comments)

So does Sodium. But do you notice how table salt doesn't burn in water?

There's no lithium metal in lithium /ion/ cells. The whole lithium catching on fire thing is to do with them having a rather volatile solvent as part of the electrolyte (something similar to ether).

Helsinki Aims To Obviate Private Cars

mirix Re:a matter of scale (276 comments)

Which is why they are trying to remove cars in Helsinki (LA), not in all of Finalnd (california).

North part of Finland has much lower density than parts of CA. I'd imagine a car is even more essential there.

Wheel Damage Adding Up Quickly For Mars Rover Curiosity

mirix Re:Poor material choice (162 comments)

Only modern, pressurized aircraft. Cave tech like the DC-3 are made of aluminium, have square windows, and have no problems. Even ones that have been flying for 70 years.

Wheel Damage Adding Up Quickly For Mars Rover Curiosity

mirix Re:Odd material selection (162 comments)

Historically cable lacing was done with waxed cotton. Since WWII more nylon and polyester, as they wear harder and don't burn as good, don't like water, etc.

I'd imagine NASA uses some kind of space age stuff.. polyimide or some sort of fluoropolymer, but who knows, maybe cotton has better extreme cold weather performance.

We'll run out of oil long before they ever get fusion working.

Netflix CEO On Net Neutrality: Large ISPs Are the Problem

mirix Re:Conduit lease (181 comments)

Dream on. What do you do when someone doesn't want you pulling cable across their property? (You won't be able to get the government to force them.)

It's besides the point really. Without government you'd be pulling the cable down a road made of mud and shit anyway.

California May Waive Environmental Rules For Tesla

mirix Re:Screwed... (327 comments)

CA still out-manufactures every other state. second place is texas, Though CA has a bigger population.

It's had some decline in manufacturing, sure, but it's never going to be like detroit. Hell, even if they quit making things entirely - CA will never be detroit, between IT, hollywood, tourism, service BS, etc.

Reversible Type-C USB Connector Ready For Production

mirix Re:Good. (191 comments)

That's kind of a bullshit complaint. Do you currently plug your phone into a USB A to USB B adaptor, to a USB B to USB mini B adaptor, which is plugged into a USB mini B to micro B adaptor? (yeah, I skipped some USB variants).

No? then shortly you'll just have a USB micro C cable / charger, same as how you have a micro B cable / charger now.

Reversible Type-C USB Connector Ready For Production

mirix Good. (191 comments)

I know, one more USB connector to have an adaptor for... But this is how the mini/micro and even old USB 'A' should have been from the beginning.

There's nothing worse than having to blind mate USB, and having to flip it four bloody times before it works. (except maybe blind mating 'F' connectors, or sometimes D sub..)

3 Congressmen Trying To Tie Up SpaceX

mirix Re:Follow the funding (393 comments)

Well, the Molex bit is kind of a stretch, to me. They make connectors for _everything_, not just aerospace. I'd imagine aerospace is a pretty small amount of their business?

Looks like molex runs about 10% of the global connector market. 70% of which they generate outside of the US. Kinda surprised me their share is that small.

I think defense and areospace use more connectors by Amphenol, or Cannon (now ITT). At least they did 40 years ago.

Earth In the Midst of Sixth Mass Extinction: the 'Anthropocene Defaunation'

mirix Re:But what IS the point they're making? (342 comments)

But when concrete sets, it does so via reabsorbing the CO2, right? So it should be a net neutral (minus CO2 from the fuel to cook the limestone in the first place).

CaCO3 + heat -> CaO + CO2 (in air)

Add water, get Ca(OH)2, which reacts with CO2 from air to set... back as CaCO3 and water..

Or did I miss something?

California In the Running For Tesla Gigafactory

mirix Re: Nevada is the only candidate (172 comments)

I guess the compound mustn't be 1:1 Ni:Co as written, as some site shows Co and Li being 10% of mass, and Ni 50%, for reasons I don't entirely understand.

In that case Ni is by far the biggest cost, and Cobalt is still a bigger share of the cost than lithium.

It must actually be a mixture of LiNiAlO2 and LiCoAlO2 or something like this? my distant highschool chemistry is failing me.

Upcoming wikileaks release to stress american ties

mirix mirix writes  |  more than 3 years ago

mirix (1649853) writes "CBC reports that the US has told Canada that an impending wikileaks release may cause a negative impact on US ties with foreign nations.
Apparently the US is also informing other nations of the release — It could be pretty damning if they are bothering to notify foreign ministers beforehand."
