China can do massive infrastructure projects because it has a very efficient authoritarian government. They make a decision and get it done, for better or worse.
Wasn’t part of the criteria of the original funding grant that the project could be scaled back to derive direct benefit from the funding without needing additional full construction of the high speed rail?

It depends. We now have this little thing called the Internet, and you can quickly learn a ton of things on it. Even if you just learn a few points and without all the details, that's still better than nothing and at least a starting point for further study, if needed.

And it depends on the direction of the answers too.

For example I think most autoland still require some amount of visibility a few seconds before touchdown, and the pilots are supposed to go around if they do not have it. Plus, I believe planes also use a radio altimeter while landing. But I don't believe they use GPS for the final approach.

So you might put a plane in a difficult position with that kind of attack, but not necessarily making it crash. And there are probably more easy ways to do more damage.
I remember being astonished when I first saw images of the purported documents. I could not believe this got past anyone at CBS news, let alone Dan Rather. Did they have no memory of what manual typewriter type face looked like?
That's atypical of most high income, high quality districts in California. E.g., Palo Alto is currently fighting with Stanford over a housing expansion because of the impact of additional students at local schools.
Except, that's not actually the case as you still have latency between servers.
In that same podcast Alex said that he had more or less stopped soloing easy routes, reserving solos for rare big accomplishment climbs, which makes a lot of sense to me. As a long time climber, I can't think of a single climber who died on an extremely difficult solo, but can easily name a half dozen or more elite climbers who died on easy terrain.
I hate the way the website is laid up, everything is shown in a similar font face so you have to read ads and titles of unrelated questions before you can find the text of the answer... which will surely be written by someone with economical interests in the field.
The statistics tell me a different story. Seasonal differences in the renewable share are almost nonexistent. Maybe somewhere around +-20%. Sure we will need storage that lets us bridge weeks and if it is economic even up to a whole month but anything beyond that is not about trying to compensate energy shortages, it's about capturing the overproduced energy to sequester carbon.

https://www.energy-charts.de/ren_share.htm?year=2018&source=...

Also I recommend you to take a look at the daily variance.

https://www.energy-charts.de/ren_share.htm?year=2018&source=...

Anything below the average of 40% is awful. The longest interval below 40% I have found was from 19.03 to 29.03. A month of storage is more than we would ever need. two weeks would be the sweet spot, one or zero weeks is doable if we use gas plants. Really the only amount energy storage that I would consider absolutely mandatory is 24 hours because we still want to use solar energy at night and wind power that is mostly generated at night during the day.
>I thought America in general and California specifically had the world's best engineers.

Where on earth did you get that idea? Japan and Germany have long been known to have the world's best engineers. The only engineering that Americans have really proven themselves to be the best in the world at is software. There were times in the distant past when they were best in the world at other things, but those times are gone. There might be an exception for military technology though; no one builds aircraft carriers like the USA still.

Remember the Apollo rocket program? How did America do that? They brought in a bunch of Nazi engineers, remember?

As for when America stopped doing "hard" things, I think it was somewhere in the 80s or 90s maybe, though from what I can tell, the really big turning point in this country was 2001, but things were falling apart before that too.
in a current climate of talent shortage in tech and especially in machine learning/deep learning there is really no excuse for going to FB
In final accounting, in the words of the authors:

These results suggest that for individuals on the current policy margin between prison and probation, imprisonment is an ineffective long-term intervention for violence prevention, as it has, on balance, no rehabilitative or deterrent effects after release.
It is not only ethnical.

With SO much negative press, I feel that Facebook had lost its mission among wider public. If it is net bad for the society, even just the perception of it, it is hard to hire someone who shared that vision with you, only mercenaries.

Good people are weird, though. They work for money, like everyone else, but not just money.

Let's say that the project is a very large, somewhat famous public open source piece of software that has been coded on by many, many different people with different coding styles.
True. Those same executives who are working the '80 hour week' include lunch, cocktail parties, dinners, etc. into their hours, as for them schmoozing = work.
Sensible analysis but will be ignored by the current administration.
All the best minds in America are devoted to either getting people to click on ads or fleecing them out of their retirement savings. There's nobody left to plan out infrastructure work or make the government function.

Back in 2015 I did a webinar session for CIOs titled

Data Science: Trenches to the Boardroom (10 Lessons)

The definition I was using at the time was:

Multi-disciplinary knowledge, methods and skills for building systems that acquire, manage and analyze data to deliver insight and automate quantitative analyses like segmentation, classification and prediction in support of real-time business processes.

I focused on the building of systems that automate analysis. I did this in an effort to distinguish what I am now doing from my previous work as a "research-based consultant." In that role I would take on a business problem/question and use a variety of qualitative and quantitative techniques to investigate and come to an evidence based recommendation for the client.

But now, I build systems that often automate away the work of an entry level analyst. Or, use the models to drive systems that automatically adjust prices to changes in the competitive landscape on a SKU by SKU basis. Or, build systems that create added-value data sets that are in turn sold to another company.

an idea has a better chance of building rail infrastructure than a nation-state? Dubious.

You seem to be drawing an impossibly broad conclusion. I have taken the liberty of editing your concluding statement by adding an appropriate amount of uncertainty and removing overly general statements.

Here's what it says: ''
Op missed the part where they need to batch run their solution 200 times over and pick the quickest root. Like always ignorance begets confidence. That's not even talking about part 2 which you need to completely refactor the solution from the previous problem.

You sound like the type of engineer I get hired to replace at three times the rate when the project is on fire because they didn't understand the spec.

I imagine that in China it's orders of magnitude easier to force people to leave their homes if the government wants to build over them
It's not a particularly subtle or difficult point. Every time the government touches anything having to do with money, it has a redistributive effect.

For example, if the government limits who has standing to sue under environmental statutes, and decreases enforcement, it redistributes wealth from the poor who were using a natural resource to any company that may have polluted or depleted it.

The comment to which I was responding said explicitly that "capitalism has drastically increased quality of life" and that "[m]ost of the 20th century’s biggest failures were due to government intervention." Talking about the weaknesses of capitalism when it is unfettered by government intervention is clearly on-point.

On the other hand, I don't see anyone saying redistribution should be "a primary goal," as you characterize it. Where are you seeing that?
> When did America stop doing 'hard' things?

Basically the 70s. We never really recovered, even if the economy did.
Have these people never read Harrison Bergeron? How do they think this is going to end?
The death of the ‘Like’
It was an awful bill. It removed density limits in any jobs-rich area (so basically all of the Bay Area). It forced any single family zoned area to allow fourplexes.

This would have greatly changed the character of neighborhoods that people have lived and invested in for decades. If you can't see the political problem with that, well, you might want to learn more about California politics.
Since other systems are also fragile, we shouldn't care about adding one more? I'm pretty sure I'm against that line of thinking.
You can probably do even better than 20-30ms round trip if you're one of the large Cloud companies with data centers everywhere. Amazon so far doesn't seem interested, but Google and Microsoft definitely have the infrastructure to pull it off.

Sure you won't get high end PC gamers, that's not really the target demographic here. It's the millions of console and mobile gamers.
German usually packs descriptions into "single words" by starting with some base, like "meat" and further qualifying it with other adjectives but without a space. You can get away with not knowing every part of the word and still get the gist of it in the same way you might not know a word in "Cattle marking and beef labeling supervision duties delegation law" but still get the gist. This is an oversimplification of course.
What does any of what you wrote have to do with whether or not it's savings. You're just saying you think some forms of savings are better than others.
Look at a map. I5 is NOT where the rail was going to be built.
After your expenses, you still have 28k (post tax $ per month) - 12 (added all your expenses) ~ 16k per month = 192k per annum. 192 - 38 - 15 = 139k still left after taxes, expenses, 401k, and 529. Isn't that a really huge number?
Montana has 1 million people, North Dakota has <800k, while California has almost 40 million people. California problems are US problems.
Yup. The more that move out of the Bay Area the better. There are a lot of other nice places to live. It would be awesome for those nice places to get good tech jobs.
I asked one, who pointed out he'd like to make change from within rather than blog about them being evil from the outside.

I don't know which way is right.
The cost of HSR would make it an alternative to flying, not driving. SF to LA is a $50 of gas. HSR tickets would be at least $100, and maybe $50 of Uber’s. For a family of four, a $50 trip turns into a $500 trip.

We know all that because we have inter-city rail on the east coast. It’s an alternative to air travel, not driving. Normal people can’t afford $500+ round trip for a family trip from NYC to DC.
yes, the value of upzoning accrues to land value, not the real property that sits on it, but the rest of your conclusion doesn't follow.

when demand outstrips supply adding a different type of supply (like an apartment building) won't depress prices materially (for detached single family residences). they're different market segments.

also, you don't need to tear down the home to realize gains, since, as you yourself said, the value accrues to the land, not the building. the price would immediately incorporate that value, without the need to replace the structure atop.

if you also want to gain rental income, then yes, you'd need to replace the structure, but that's an investment to unlock a different income stream.
You are technically correct, it's just that when the vector of booleans gets long enough they start to exhibit certain properties that "normal" binary vectors don't have. Because of this the authors use the term "hyper dimensional vector" to let other professional researchers quickly know what they are talking about. Here's a decent blog post about some of those properties: http://gigasquidsoftware.com/blog/2016/02/06/why-hyperdimens...

I kind of agree that "hyper-dimensional" sounds like a dumb buzzword, and maybe it is. But I do think we should have a word for vectors that are big enough that they fall in this regime.
I feel like a big part of the reason America fails at this is jumping from high speed rail (proven tech since the 1960s) to flying autonomous taxis (coming any day now, right after flying pigs).
>Why? Censorship is quite a different issue from anti-trust.

Is it in this case? The censorship here is only effective because of the failures in anti-trust to adapt to the modern internet tech giants. If you are pretending that these companies aren't monopolies in search, video delivery, messaging, and social media... Well, I disagree.

So I get what you're saying, but let's not pretend Microsoft in 2000 was larger than Google or Facebook is now.

The issue is that these companies are clearly pretending to be PLATFORM when it suits them, and PUBLISHER when it suits them.
I agree with you: the angle of "helping lower income people" is weak and moralistic.

That said, the unfairness of single family house subsidies will have tremendous impact on the long term suitability of the state. CA does have a high homelessness and house poverty problem. San Francisco is already a dump: literal human poop on every street in front of million dollar condos built in the 70's.

Once tech diversifies away from CA they are toast.

A while back I built something to mimic a day-night cycle: https://github.com/wpietri/sunrise

My original goal was to counteract the darkness of winter, which impacts my mood and productivity. But the thing I like best about it is that the lights dim in the evening, so I actually go to bed at a reasonable hour. Whereas with manual lighting, I can easily leave the lights on while doing something, not notice the hour, and throw off my sleep cycle.
I didn't need one to know that, but I was surprised by how little drinking would change my resting heart rate (even two beers at dinner might keep my heart rate elevated for half of the night) and by how much/how long heavy drinking can affect RHR/HRV - a heavy night might affect RHR for 2-3 days...

Ask HN: How do you manage references to project resources?
You may have docs hosted on Google Docs or Dropbox Paper. Multiple repositories on GitHub/BitBucket/GitLab. If you are a web developer, you must be referring to Invision/Zeplin/Figma often.

Obviously, a single project can have tons of related resources — docs/code/design mockups/media assets/others. How do you track such references? How do you keep your teammates informed on where to get the necessary piece of information, required for a project?

Do you keep these references in a single place, e.g., some page/section of your project management software, or maybe README.md file of a project code repository?
1) For most selective colleges, they'll be living in a different neighborhood or different city, in a college dorm instead of their house, with classmates instead of parents & siblings. So almost everything is different.

2) Sure. Environment has both short-term and long-term effects. So a fraction of the environmental effects wear off. I dunno what the fraction is, but when you do the regression to find the weighting of SAT test score and adversity score that best predicts college achievement, it should find the right balance.
Well, at least you aren't being hyperbolic

My understanding is that the French offered to build out HSR along I-5 between SF and LA during the Great Recession and California said they could do a better job for less money.
This is the reality of the situation that people don't want to admit. This is a social engineering problem related to the outcomes of college entrance processes. It's not really about the test or how we are measuring aptitude.

This problem would be far better solved elsewhere in the chain instead of blurring the meaning of data and pretending that things are different.
They also lose everyone not interested in streaming games (like myself). I'm sure they've run the numbers, but I know plenty of people who actively purchase games and are not at all interested in streaming them.

If you can get the airplane to descend early to a decision height 200 feet above touchdown zone elevation in an area where local terrain is 150’ above TDZE, you might be able to crash one who initiates the missed approach at the DH.

I agree it’s not a practical attack.
You're doing MRR wrong (and why it matters)
Yeah, speed of light is actually a lot faster than people think. Honestly things such as controller and display lag are probably bigger than the round trip latency. And experimentally, anyone who has tried Stadia at GDC or I/O has said that latency wasn't an issue.

The bigger limiting factor I think will be bandwidth, especially in America with the awful internet provider situation.

Its a market at work but it puts a cap on how much CA can grow. CA is already losing out enormously domestically. CA thrives demographically only on immigration, otherwise it would constantly lose people.

Actual video gamers right now go out of their way to get displays with very low input lags. 1080p144hz TN low input lag displays are used quite a bit in esports to shave a few msec. You literally win more often if you react faster. People aim to get TVs with sub 16ms input lag.

However that's not most of the market. The appeal of cloud gaming is for single player non-competitive games. These are the most pirated games and the games where input lag matters the least.

96 people died building the Hoover Dam [1]. It was built 'on time and on budget' to a great extent at the expense of lives.

That's a lot of deaths.

For comparison, only 147 total coalition deaths as a result of combat with the enemy [2] in the 1991 Gulf war, involving hundreds of thousands of soldiers, the liberation of Kuwait and the overrunning of most of Iraq.

And that's saying nothing of the comp, overtime and other externalized issues.

Of course, the failure of rail is pretty bad and we need to learn, but we can't hold the Hoover Dam up as 'the example'.

Carefully designed antenna geometry could be used to target a key sniffer on a specific machine at a distance. This would make it easy for someone disguised as cleaning or maintenance staff to target a specific machine. On the flip side, even gathering all keystrokes in the immediate area in a jumble would still yield useful data to an attacker.

As I've stated before, we're reaching the point where every device, no matter how trivial, needs to be encrypted and robust against spoofing and replay attacks.
Ok, I talked to the engineer. I got it mostly right but everyone shoots to the right as soon as the lights go out.

The question is "what's the probability you die?".

Edit: You can also challenge people to think about the problem where everyone fires at exactly the same time OR random order since people have different reaction times.

Edit 2: "The probability p(n) that a permutation of n things is a derangement -- which tends to 1/e as n->oo -- satisfies the recurrence relation p(n) = [(n-1)p(n-1)+p(n-2)]/n; is it possible that the correct statement of the problem here leads to that same recurrence?" <--- My engineer says that derangements are the correct key to the convergence.
