Interesting notes / anecdotes from me about 10,000 hours and genetics.

I played golf at a pretty high level throughout high school and college. I practiced and played golf on most days for 8 straight years. I'm sure I reached 10k hours. Currently, I don't have almost any time to practice and play golf. I haven't practiced or played regularly in at least 6 years. Yet, playing once every 2 months or so I'm still able to shoot at or near par most of the time. I suspect this has more to do with the 10k hours of practice than my natural abilities. Not really any way to prove that, but I suspect a similarly athletic person who hasn't put in that practice wouldn't generally shoot par playing 6 times a year.
In Singapore all short haul trains (called MRT) are either underground or on Pylons. Seems to work out well enough there.

Android has a few nice keyboard shortcuts baked in, including a basic alt-tab app switching menu.

Shame Apple can't see clear to adding some basic features like that for keyboard users, who while admittedly are a minority would really love to have some functionality like that.
There is a private bus service the runs between LA and SF for $40, which is probably less than the cab fare to the airport, or what a high speed rail ticket will end up costing.

In fact, I am a woman, and have been a feminist since 1974. With all due respect, feminist discourse is best when all stakeholders participate. Silencing any point of view is disrespectful and not productive. Freedom of speech seems to be a problem in this whole discussion. Wondering why?
Wow, brand new respect for Canonical here.
The pods have something similar to landing gear for use at speeds less than 100 mph. Still, what happens to pods that are sandwiched between two malfunctioning/mangled pods? I think they should have contingencies where sections of tubes may be excised safely.
This is just the tip of the iceberg. Of course the government cares about money, and of course it wants to control the money supply. And, as a consequence, the USA will never allow any major currency inside its borders other than the US dollar.

The history of the United States is littered with the fights over who gets to determine what is money and how much of it there is: Hamilton's fight with Jefferson and Madison over the need for a central bank, Jackson during his run for the Presidency denouncing the central bank--and this becoming the main issue in the campaign, the popularity of Williams Jenning Bryan (cf. the famous "Cross of Gold" speech), etc. etc. all the way up to the horrible stagflation of the 1970s ("Whip Inflation Now!") and the recession caused by the ultimately successful efforts by Fed Chairman Paul Volcker's to end it. It is reasonable to believe--and certainly most people in the US government believe--that control of The Money is control of the economy.

Why would any successful government ever voluntarily give up that control?
This argument is like saying he's an opponent of extramarital affairs, but he's in bed with his wife.

Of course he's with the government employees unions, he has to live with them every day.
But why would lots more people start going from LA to SF or on any of the other routes? As a comment to your previous comment below asks[1], what would the economic gain be?

There might be a bit more interaction between LA's entertainment industry and the Bay Area's tech industry, but how many additional people would be travelling for this purpose?

I expect that, given that the northeast corridor comprises the nation's capitol, its financial capitol and its academic capitol (the latter two also being high-tech centers), one would expect movement between these places and would want high-speed transport.

I just don't see a similar dynamic operating in CA. Sacramento cannot compare to Washington, D.C. and LA and SF are pretty self-sufficient, as I expect San Diego is as well.

I can believe that's a good plan for the US NE corridor... which already has usable (but improvable) Amtrak.

The California coastal cities (and connecting areas) are still pretty sparse, comparatively. And the marquee High Speed Rail project takes a big inland detour to the smaller interior cities, for political reasons. If ever finished, that will hurt its price/time attractiveness compared to flying.
the "persistent component that doesn't automatically update itself" that tptacek was talking about is the software used to generate keys, do encryption etc.

the safe alternative is that each user has to go find and install reliable third party software themselves. this is already possible with gpg et al and it is not used.

so instead someone needs to package the crypto code. and as soon as you do that, if there's any kind of update process, the code package can be forced (apparently) to modify the code to leak information.

so sure, you can do this securely. it's already possible, but it's not popular. and anything easy enough to be popular appears unreliable.

Slightly misleading headline: he said he will "probably" build a prototype, but still has no interest day-to-day. He is interested in investing, however.
I'm sure a lot of it works fine within the agencies, it's just the translation process to "muggle" where the problems coincidentally appear.

I wonder what the security checkpoints would be like on the HyperLoop if it ever got built? They are saying capsules could depart 30 seconds apart. Imagine is there was an attack in on of them, with several others travelling at high speed just behind.

My apologies. I don't know why you were censored, I'm assuming you know way more about this than me.

I will say though I think it's dishonest to characterize feminist discourse by what happens on twitter. If this is happening outside of the internet, in feminist groups and academic discourse, I agree that it is problematic, but not a problem that is unique to feminism.

> Cost is probably off by an order of magnitude, if not more. Why? Unions and other groups. Building anything in this country costs massively more (and takes significantly longer) than one could imagine because of our unions are not business symbiotic. The goal of union leadership is to extract as much as they can out of the businesses they infect, even if this means their demise.

Musk is in the car industry, one of the hardest hurt by unions and their ilk, so I would find it hard to believe that he didn't take that into account.

> Finally, it addresses the wrong market. I am not sure why people insist on applying trains to transporting people in the US. Sorry to resort to reality folks: If you build it they will NOT come. We do not have that culture and you will not inspire it simply by building trains.

Again, Musk is building and selling electric cars in a country that LOVES gas guzzlers. His track record would suggest that he knows what he's doing.

> Regrettably this is not a technological problem. It is far more complex than that.

I don't know why you think that this paper/concept only addresses technological issues, because it is clearly much more broad in scope than that.
I have a lot of noise in my contacts list though. Very rarely do I have a surname, mostly it's suffixed with "home", "mbl" or "work" or even city name as surname sometimes. I'm sure a "best guess" would be possible, I'm not sure of anyone that religiously stores first/last name aside from pure business contacts.

> Musk will build a demonstration prototype himself. “I think it might help if I built a demonstration article. I think I probably will do that, actually. I’ve sort of come around in my thinking on that part.”

...After which he reiterates that this is not his top priority, though if it was that it would take just one year by his estimates. I guess we'll all be looking forward to finding out where the prototype will be located (Texas?).
Link describes one-time payouts upon retirement, not recurring pensions.

"Denson also earned $407,908 in total wages in 2011, according to city data, making him the highest paid city worker in 2011. Of this sum, $212,738 consisted of "cash out" pay, which accounts for such factors as vacations, holidays and unused sick pay. His regular salary was $195,169."
The ST monad [1] provides an efficient hashtable now; doing hashtables as pure functional data structures is well know to be slow.

I would hope one wouldn't need to resort to STM for a compiler, especially since retry is fairly undefined! Still nothing about iterative computation however, I wonder how the ST monad would deal with a Y combinator?

> It would be cool if the inputs weren't matched exactly, and frak could figure out a general pattern for your inputs (decimals, capitalized words, etc).

The problem is that there are an huge number of possible solutions for any given input. For example, you could always give a trivial solution: ".*"

For something like that to work, you'd need a large dictionary of common patterns, and then you'd want to compare against the dictionary to see if it matches a sequence of common patterns.

I can't imagine that sort of thing being too useful.
The interesting bits are the details about Musk's intentions going forward:

- Musk will build a demonstration prototype himself. “I think it might help if I built a demonstration article. I think I probably will do that, actually. I’ve sort of come around in my thinking on that part.”

- For now, this is a low priority for Musk. “Maybe I would just do the beginning bit, create a subscale version that is operating and then hand it over to someone else. Ironing out the details at a subscale level is a tricky thing. I think I would probably end up doing that. It just won’t be immediate in the short term because I have to focus on Tesla and SpaceX execution.”

- If it was his first priority, he could have it done in a year. “The demonstration project would not be anything that required some sort of big government approval process,” he said.

- Musk will invest his own money into this project, even though he hopes others will help as well. “I always invest my own money in the companies that I create. I don’t believe in the whole thing of just using other people’s money. I don’t think that’s right. I’m not going to ask other people to invest in something if I’m not prepared to do so myself.”

- But it’s okay if it doesn’t make him a lot of money. “I’m not trying to make a ton of money on this but I would like to see it come to fruition,” he said. “I don’t really care much one way or another if I have any economic benefit or another, but it would be cool to see an alternate form of transport.”

It'a not clear whether Musk actually said he intends to build a proof of concept or whether the writer took his "probably" too far.

If anyone finds a more complete transcript of the teleconference, please post it.
In this case it most certainly is nefarious because it's not being used as a capital allocation tool, but as a means to get tax reductions where there should be none. This loophole allows local agencies to get paid for letting private corporations get tax deductions that they should not be getting. I may be totally off base here, but near as I can tell the correct market-based solution is probably not to make this illegal (although that probably can't hurt) but to give local agencies like BART the ability to file tax deductions in the same way the private enterprise doing the LILO is. This would remove the incentive to perform a LILO since the local agency would be gaining short term liquidity in the form of "tax returns", assuming their they can deduct taxes beyond the $0 taxes they owe by virtue of being a government institution.

Show HN: Convert your Idea to Mvp
NYC CSA is bigger than LA CSA, and DC CSA is bigger than "Bay Area" CSA. It seems weird, then, to argue it makes more sense to connect LA and SF just because in the northeast you can also hit two additional CSA's (Philadelphia and Boston, which are each about the size of the Bay Area), while you're at it.
It's quite possibly the case that it takes longer to parse the complex trie regex (using character classes, ?, etc.) constructed here than it does for a good regexp library to parse the alternating fixed strings and construct the equivalent automata.

The biggest criminal enterprise is "outside money" vs. "inside money" and the scale is orders of magnitude larger than the folks peddling narcotics or paying for hookers.

It's interesting that in Jun 2012, voters might've voted differently if asked again [1]:

In fact, some of the highest resistance to the high-speed rail project that would run from L.A. to the Bay Area comes from Angelenos, according to new data released over the weekend by the USC Dornsife / Los Angeles Times Poll:

About 56 percent of would-be voters in L.A. County would say no to the train if allowed to vote on it again; 37 percent would be in favor. In San Francisco the train would win 47-45.

About 66 percent of Central Valley voters were opposed to the train, which would run through their farm region.

Statewide, if a re-vote on the train were allowed, 59 percent of would-be voters would say no; only 33 percent would give reaffirm it.

About 55 percent of statewide voters said they'd be down for a re-vote.

The article later goes on to state:

The biggest problem for this train is timing -- California is facing another crushing budget deficit and a stalling economic recovery. Dan Schnur, director of the poll:

Californians aren't necessarily against the idea of high-speed rail. But they don't want to spend all that money right now, and they don't trust the state to make the trains run on time.

You have to push harder on the paper to make a mark. You must frequently dip the pen in the ink.
Probably you've never seen a slum, so let me explain:

- Houses are juxtaposed to each other, there's no room for windows

- Roofs are corrugated, so you can't easily fit a top glass panel even if you have the money for one.

- There are transparent, fiber glass roofs, and some people use those, but often they don't get to choose the materials used to build the house, just use what is available.

So this is a quite nice hack that works for most houses.

This is yet to be proven. Is the bitcoin network really more costly than existing payment systems? Can the security benefits, instantaneous transmission, and other features be replaced by less costly alternatives?

As the mining reward rapidly dwindles relative to the cost of electricity, there is a huge incentive to reduce the electricity consumption while maintaining the security of the network. At what point does this reach an equilibrium depends largely on the market value of bitcoin. So it should be a somewhat fixed cost in proportion to the adoption of bitcoin, just like the fixed costs of any currency (e.g. minting coins, mining gold, etc.).
There aren't bathrooms on public transportation either and yet many people still take subway and bus rides that are 35 minutes or longer.
As Balgair notes, you can get away with a lot on the short run, but leaks are notoriously difficult to patch up. Vacuum leaks are super hard to detect at these pressure ranges, where you're lucky to hear or feel them at all. More than likely, your only indication is to leak helium into the system on purpose and use a mass selector on the outside to 'sniff' for ambient helium (which is extremely rare normally). It's terribly slow and time consuming.
You can always take the short cut and just sorta gunk up the leak to mitigate it, but eventually it'll wear out. Vacuum welds are far better, but also take a lot of skill to perform on the spot: any sort of crevasse will act like a leak (albeit a small one - at these pressures it probably won't matter), so the bead needs to be nigh perfect.

Or you just slam another plate on the outside, glue/weld it up and just sorta not worry about it. Heavy pumping covers a multitude of leaks.
I (and I'm guessing some of the people involved with Julia) would argue that regardless of how good the numerical programming tools are, you'll never get the average working scientist to use Haskell. That sounds like an interesting project though, I've become curious lately about the prospects for integrating high performance numerical computing with functional programming.
