Comment Re:I wonder how long... (Score 3, Insightful) 50

Well, they're already opting to have damaged natural joints like hips and knees replaced. That's a case of upgrading from natural to artificial to gain function. As the performance of artificial limbs increase, it might become an increasingly commonplace treatment for older people, just like knee or hip replacement.

If we project that trend forward for twenty or thirty years I wouldn't be surprised at all to see artificial legs that outperform natural legs for the purposes of walking or even running. But I don't think people with normal abilities will be trading in their limbs just to be able walk a little longer, run a little faster, or carry more weight. That won't happen until the replacement is subjectively indistinguishable from the real thing; until you can feel the grass under your toes.

I'm comfortable predicting locomotion parity in the next fifty years, but I wouldn't care to speculate on when we'll see sensory parity.

I have no problem with going after people who steal trade secrets, anything more than I have a problem with going after people who steal nuclear secrets. The only thing is that the FBI has a long history of racist paranoia about Chinese scientists, from Quan Xuesen in the early 50s to Wen Ho Lee in the 90s.

Rhwew may well of a legitimate case against these guys and if they do I hope they nail the bastards. But I'm not jumping to any conclusions based on FBI say-so.

You're the one worried about passwords that can be broken in 25 years; that's a non-issue. The issue is security that works well enough for long enough and is workable for the users. Impressive sounding, inflated requirements means something else has to give: price, performance, or usability.

Well, once you've cracked the VPN traffic the password is almost a secondary concern, isn't it?

This is the wrong way to think about security, e.g. for a hypothetical world where users adhere to anything you demand of them no matter how intrusive or onerous that is. In reality if you decide that usability and convenience aren't factors in your planning then that's actually an oversight which will come back to bite you on the ass someday. The only thing you can say for that approach of wishing usability away is that when disaster comes you'll be able to point the finger of blame at the users -- even though their non-adherence is a predictable result of your poor understanding of system requirements.

Comment The last, lagging symptom of inflation (Score 3, Insightful) 1094

I'm normally pretty libertarian when it comes to issues like this, but it doesn't surprise me especially in a state like California where the cost of most things has become overinflated. Wages are typically the last thing to rise...but something is different here...

The government's "basket of goods" used to calculate inflation is blatantly false and misleading, as are its unemployment numbers (look at U3, not the cooked statistics you hear on the news that were called out by Gallup's top guy). Particularly in a state like California where most of the population lives in a few densely-populated areas with horrible traffic and ever-rising rents and house prices, inflation has already greatly impacted individuals. The federal government has already encouraged this by making the FHA loan conforming limit different for high-priced California areas. Between this and speculators buying and sitting on houses as investments, the average slug has zero change of owning a home and struggles even to rent due to the growing techie population.

The difference is that the gap in overinflated places like California has been extended beyond any reasonable means by expansion of debt. It's all about the monthly payment for a good, not the total amount out of your pocket for that good irrespective of repairs and devaluation. Between the large bank failures and the constant pumping of the money supply, it appears that the debtors will win and the savers will lose at the expense of substantial amounts of inflation simply because compensation for productivity has to be based on something somewhat tangible, even if it's intellectual property. That underpinning simply isn't there. This is a giant souffle that will be hardened into place from the top and pull the bottom up with it.

So yes, raise the minimum wage if you will. But those prices will be passed along to consumers. Those in LA and the rest of California and like places should get used to $9-$10 McDonald's meals and $2 cans of soda and $2.50 for a basic pack of gum. Other than austerity and contraction (which may cycle multiple times between inflation before all is said and done), this was the only possible outcome whose chickens appear now to be coming home to roost. Welcome to the new normal, with effectively no consolation for the minimum wage earners.

Originally Susan Richards' powers were turning invisible and creating a force shield around herself. This wasn't for doing cool things, it was for staying safely out of the way while the boys did the fighting. By the mid 70s when I was buying comic books her purely defensive powers were upgraded to being able to produce a shower of spherical force bubbles, which on the offensive force scale was about one step up the awesomeness scale from telekinetically throwing couch pillows.

I don't think the reason for this change was to throw a sop to feminists, or because fans were demanding strong female characters. In either case she'd have got a more impressive upgrade. I think it was simply upgraded storytelling. A character that can basically hide and shield herself is not as versatile as a character than can do useful things. So this kind of incremental upgrading naturally gave her more of a swiss-army knife skillset.

As for modern superheroines having multiple, I have not much to add, other than an observation. This multiple super-power thing kind of mirrors what we expect women to be like today. We expect them to be able to multitask, to juggle several very different roles on our teams. Versatility has become a cultural expectation for women, so it might not be coincidental that female superheroes get more of toolkit rather than one very big hammer.

Comment What High School Students Need to Learn (Score 1) 302

...about computers.

Yes, they need to know how to read, write, type, and do math, but this question was about computers.

Students should know how to convert base-10 numbers to binary.

They should understand how to map a character set to binary.

They should understand how to add two numbers in binary and then--time permitting--learn about AND/OR/XOR gates.

They should understand the concepts of CPU/memory/bus/network/storage and transferring data over a wire.

They should understand that a network can be wired or wireless.

They should understand what a cloud computing facility looks like and how their files get to/from it.

After the above, given time, you can teach them enough so they can decide whether or not they want to pursue a degree in computer science. This might include parsing a language by hand, talking about simple algorithms and algorithmic complexity, introduction to the Turing machine and computability, and maybe some simple data structures like arrays and linked lists.

Each of the above concepts can be absorbed and exercised in a week.

Comment Re:One Assumption (Score 1) 609

A second assumption is that parties don't reinvent themselves. Of course they do; if they're to last they have to reinvent themselves every generation or two. Go back through the history of both parties since the 1850s; ideological continuity in both cases is a fiction that papers over a series of opportunistic shifts in focus.

An empty shell of a party in a two-party system is like the shell of an abandoned building in Manhattan; the real estate is too valuable to remain unoccupied. So some time in the next twenty years as its demographics becomes untenable the Republican party will radically shift focus, with some kind of face-saving formulation that presents the fiction of continuity, or even a return to longstanding principles. This is just like the post-Reagan rightward shift in the Democratic party as the DLC became dominant in national Democratic politics. The old style social democratic (using European terminology) FDR Democrats remained with the party because they had no place else to go in a two party system.

Likewise the rump of the current social conservative and Evangelical Republican party will be made a welcome but impotent minority in the new Republican party. They'll get occasional lip service at in-party functions but they won't be allowed near the mic lest they spout what sounds like grandpa's crazy talk -- pretty much like the FDR style Democrats were treated by their party in the 90s and 00s.

Show me the part of the US Constitution that says the Feds can tell a State it can't regulate its political subdivisions.

Easy-peasy. I don't even have to google it. The Interstate Commerce Clause. All you have to do is find some pretext that says the regulation affects interstate commerce in some way and the feds can quash it.

In this case the issue to use is plain as a pikestaff. By preventing municipalities from providing high quality internet service the state is hinder access by out-of-state vendors to consumers in that community. That justification is WAAY stronger than other that have held up to scrutiny.

Comment Re:cover everything with mirrors (Score 2) 185

Sure, but the laser beam itself is less than ideal too, as it its targeting. We're talking about hitting a moving target from another moving target with a less than perfect beam dispersed through whatever's in the atmosphere between them. Adding reflected waste energy to that equation and mirroring might not be perfect protection, but I'd bet it could make the attacker's job a lot tougher.

I have no doubt that at short range under laboratory conditions lasers can burn through any mirror conceived by the mind of man. In real world conditions I suspect it'd be a lot harder to get to work even without an intelligent enemy dreaming up countermeasures.

Sorry, I can't take seriously a paper on the development of constitutional law which starts with an analogy to Star Wars.

Why not? The point seems to be that a people's view of their constitution is a myth-making process. This idea is of course anathema to Americans, although clearly long-held interpretations of the US Constitution certainly color what we see as the "plain meaning" of the document.

But you can see see this consensus myth thing clearly over in Britain, which doesn't have a written constitution. That doesn't mean they don't have a constitution; it's in what nearly everyone agrees traditionally can or cannot be done. The Queen can't veto a law by withholding her assent, because it's just not done.

Comment Re:Amtrak's existing signal system (Score 1) 393

I'll bet it costs a bundle to make sure it works as well as it is politically necessary for it to work. It's a matter of marginal costs and benefits. Train travel is already extremely safe; adding safety measures to an already safe mode of travel is bound to be challenging.

Imagine a world where half the train engineers were stoned out of their mind,and train derailments were an everyday occurrence. It would be cheap to design and install a safety system that would be a huge success by cutting down derailments from a twice a day occurrence to a once-a-month thing. But we live in a world where passenger train derailments, though terrible, are exceedingly rare. They're not even a once-a-year occurrence. This is the first time in a very long time an Amtrak train has derailed for speed. In the past five years the vast majority of Amtrak accidents have been things on the tracks that shouldn't be there or freight trains colliding with Amtrak trains. The last accident a system like the one we're talking about would likely have prevented was in 2011, when an Amtrak train went through a red signal and collided with another Amtrak train.

In our hypothetical scenario if the new system caused one accident a year that'd be a non-concern because of the hundreds of crashes it prevented. But in real life if the system caused just one accident a year that'd represent a tripling of the accident rate ove no system.

You have to have confidence that an automatic system outperforms humans by an order of magnitude before it is accepted by the public, underwriters, investors etc. Otherwise self-driving cars would be a commonplace option already. They already work, probably better than drivers and certainly better than some.
