I can't believe populist sentiment among programmers. This job can be done anywhere. You want to compete with immigrants, who have your same cost of living!

But that misses the most fundament point in all these "they turk or jurbs" arguments. You can't keep the business here by keeping immigrants out. If you want the US to be a center for the good programming jobs, then you must be pro-immigrant, because those jobs will go wherever it's easiest for programmers to legally assemble (it's not like you easily can spot the top 5% - you hire as many "good" programmers as you can, then observe their actual performance). If you want just the shit jobs to stay here, and all the best jobs to be elsewhere, then by all means get your immigrant hatred on!

Advances in renewables, particularly PV, are what will lead to electric cars going mainstream eventually. When you get to the point that someone's solar panels can cover their entire house's electrical consumption AND charge their car every night there's no more room for argument.

....as long as you have no intention of going car_range/2 further from your house... Otherwise you're still looking at a commercial infrastructure.

This is seriously one of the first things anyone in security would have thought up

Ah, the /. 30-second expert. Indeed, the TOR guys did think of that too.

Malicious exit nodes do not per se compromise TOR, though they are in a position to take advantage of some potential exploits (also, exit nodes are irrelevant to .onion servers) It's been known since the start that if an attacker both controlled the exit node and could directly tap your line, there'd be and endless stream of exploits possible - and IIRC the NSA had just such attacks in its arsenal. But that doesn't scale - you have to be actively monitoring a specific target to de-anonimize them, you can't do it to everyone. If the NSA actually got warrants when they did that to Americans [pause for laughter] I think it's a fine system.

TFA seems to be about taking over more than half of all TOR nodes, which can hardly be done in secret, and really makes 0-days in the TOR bundle visible.

Far more worrying, especially for the conspiracy theorist, is the never-ending stream of vulnerabilities in .onion servers allowing the operators to be de-anonymized. It's hard to believe TOR wasn't designed that way. TOR seemed designed from the start as a system to let Chinese dissidents use American servers safely, but not allow Silk Road-style sites (servers illegal in the US) to stay up. That IMO would be pretty cool if the US itself weren't growing ever more repressive.

I'm pretty sure that storing electricity is pretty problematic. You are talking about storage batteries. Not very realistic for large amounts of power. (When compared to methane which you can store in a tank).

How about this -- use electricity to power a pump that pumps water up hill to a cistern. Later, have the water run downhill and spin a turbine to produce electricity. Essentially storing electricity in a tank.

In fact, strike that, this is simpler. Have your solar cells pump water to the cistern for all the hours the sun is in the sky. Have a separate pipe in which the water flows down hill to spin the turbine, which is your power source. The cistern acts as a ballast, storing energy during peak production times to be used during times of low or no production.

I confess, I was not impressed with the practicality of the all-electric concept, and felt it would always be pretty much a rich person's toy. Common in Hollywood and maybe the Silicon Valley and around Wall Street, and maybe Redmond, for bragging rights, but you'd never see one in Omaha.

The two issues as I saw it were range and charge time. (Cost is also a factor, but cost usually goes down over time.) It looks like Tesla is making a good faith effort to tackle the range issue, and there is some effort being made to reduce the charge time. Good for them.

It also occurs to me that for self-sufficiency, all-electric vehicles may be an advantage, as electricity could be easier to make and store than methane, for instance.

Actually you can use Emacs now indeed, with current memory sizes 'eight megs and continiously swapping' won't happen anymore :)

That's actually true. Very good point. And considering there's an Emacs plugin to do pretty much anything and Emacs runs on pretty much every platform, there's really no reason (anymore) to use a different editor for anything. Ow, I think the master just struck me on the side of the head. The master speaks: "Emacs is not an editor, Emacs is an operating system".

(Before the editor wars start anew, this was written somewhat in jest. As a sysadmin I had to support Emacs, but I remain a VI user. And yes, I know there's an Emacs plugin to emulate VI. Which is precisely like mounting Volkswagon Beetle controls in a Mack truck.)

Why presume that programmers (or anyone) have to travel from distant lands to the US in order to have an impact? Why not stay in whatever country they currently reside and try to have an impact there? Granted there might be more cutting edge stuff going on here (or there might not -- I could make a case that stuff happens everywhere), but in countries on the verge of being first world, wouldn't there be more to do there? At very least, wouldn't there be more low hanging fruit?

I guess I'm asking, why should we all compete for the subset of opportunities contained within the US? What, there are no opportunities elsewhere? (Actually I know there are, as I worked in India for awhile as a contractor, and have turned down jobs in Germany and Turkey.)
