Google Offers a Million Bucks For a Better Inverter

surd1618 Re:110 or 240v (260 comments)

These different patterns all exist for motors. 3-phase simplifies the design and deployment of induction motors used in industry. That is all. There's not a substantial difference between the efficiency or simplicity of various AC output formats. The various phases exist for historical reasons.

San Francisco Bans Parking Spot Auctioning App

surd1618 I got it! (404 comments)

I thought of the solution!
Just be a good person and work hard wherever you live. That way, you, your kids, and your friends won't want to move to a fuck-all overcrowded megapolis and scratch out a living in a hyper-competitve environment just to try to 'get ahead'. Simple. No more parking problems.

In the year since Snowden's revelations ...

surd1618 Re:I downgraded (248 comments)

Sorry to reply to myself but I noticed I should be clear. When I said 'clip it at random points' I meant everywhere, so if we're encrypting ASCII then scramble it up into chunks no longer than say 10 bytes.

In the year since Snowden's revelations ...

surd1618 Re:I downgraded (248 comments)

https://qrng.physik.hu-berlin.... for instance, or others. And to deal with the fact that a man-in-the-middle could intercept your pad, just download somewhat more than you need and clip it at random points (okay since we are talking crypto, pseudo-random). Then so long as the contents of the DVDs are never revealed, there will be no way for the man-in-the-middle to know what part of the pad to use to decrypt your data. Supposing it was text and they ran an algorithm to test every offset of the potential pad against your encrypted message, they would get about a bazillion false positives. Really I suspect dev/random would be good enough for most anything so long as the copy was physically delivered to the recipient. I hope someone could actually make a guess at how long it would take a computer to decrypt an ascii email padded with stored dev/random data so long as the interceptor could not access the stored pad (although maybe they could discover info about the system that produced it).

"Super Bananas" May Save Millions of Lives In Africa

surd1618 No Need For Engineering (396 comments)

According to Dan Koeppel in his book linked here, Banana: The Fate of the Fruit That Changed the World there are scores of species and varieties of bananas. Many have annoying seeds, but many also have large amounts of vitamin A, and Koeppel discusses the fact that on some islands these are a major source of vitamin A for the populace. So, I'm not dead-set against GMOs, but why should anyone take the risks (even if they are low), when we could instead merely introduce more cultivars already bearing copious amounts of vitamin A, and let the best one win? This would not only avoid the whole GMO issue, but it would also introduce new flavors, and may reduce the chances of the plants from being wiped out by Panama disease or black sigatoka, which threaten bananas mainly because likely every banana you've ever eaten is genetically identical, which usually predisposes a population to diseases, if you didn't know.

US To Auction 29,656 Bitcoins Seized From Silk Road

surd1618 blockchain secrecy (232 comments)

I have not followed this topic very closely, but I think this is a sufficiently specific question with a sufficiently complicated answer to be worth asking: because people have to make large purchases I'm sure there's names involved, so will these transactions de-anonymize Bitcoin to a great extent? I understand agencies can already track specific blockchains if they really feel the need, but I wonder if this will make it much easier.

Fixing China's Greenhouse Gas Emissions For Them

How did this comment get modded -1? It has a thesis and some data. Maybe someone doesn't agree, but that's no reason for a neg mod.

surd1618 I downgraded (248 comments)

What's the point? I can't hide. If I really need security between two endpoints I'll mail them a DVD of quantum random data and I'll use my matching DVD as a one-time pad. Short of that, apparently nothing works.

Daniel Ellsberg: Snowden Would Not Get a Fair Trial – and Kerry Is Wrong

surd1618 the article hyperlinked through 'strongly' (519 comments)

I couldn't find a full copy of Melville B. Nimmer, “National Security Secrets v. Free Speech: The Issues Left Undecided in the Ellsberg Case", but for anyone who wants to dig in, here's a link to a preview of the article in jstor. It says you can sign up for free and you get to rent articles for 14 days.

New Federal Database Will Track Americans' Credit Ratings, Other Financial Info

surd1618 Re:Credit rating databases aren't new (294 comments)

and can pretty easily be displaced

Except they're all turning into cartels. Classic example: Ma Bell was all busted up, and step by step all the baby Bells got permission to unite with their little neighbors, and now we have a few corporations that have divided the phone service into market segments, all of which have Bell heritage. Some markets, like say grocery stores and many emerging products, definitely still compete, but wherever there's big money, increasingly there is collusion and shell-game competition. Cheers for Elon Musk, though.

Which desktop environment do you like the best?

surd1618 Openbox on Crunchbang (611 comments)

I like the implementation of Openbox on #!. It does things one wants to do, and it has 1 way to do each thing. I don't see the point of wasting electricity and hard drive spins by having 10 ways to do things, or spending time pairing away everything I don't use in a big desktop environment. Close 2nd is XFCE on Debian or Arch.

'Curiosity' Lead Engineer Suggests Printing Humans On Other Planets

surd1618 Takes away the romance (323 comments)

On the one hand, the rational thinker in me says that sending ships to other places, where machinery will make humans, might be the only way that humans ever get out of here. OTOH, I want to see another planet with my own eyes. So, I think this is a good idea, but it makes me sad.

US May Prevent Chinese Hackers From Attending Def Con, Black Hat

surd1618 Re:better idea (193 comments)

You can trash the US all you want, but there are a limited number of countries in the world that would even allow a conference like Def Con or Black Hat.

Maybe the US allows these kinds of activities because there's so much power here that it's not perceived as much of a threat. I doubt that things will be so free and open here when we use up all of our natural wealth.
