> red state prisons sit full of petty dime bag dealers

Does anyone know where to get at the raw statistics for this kind of information? So that we can figure out how many prisoners there are in red states vs. blue states for marijuana possession?

Another fun twist would be to see what effect there would be if you mentioned that no one from Puerto Rico voted for Hillary Clinton in the 2016 presidential election.

Anyone have a good estimate the total amount of money spent in the name of education in the U.S. in the last 50 years? I'd be interested to see the total pre-k through university graduate school, including both public (local, state, federal) and private.

That sounds awfully static. The interesting thing will be to see if people with unconditional money end up becoming addicts at higher rates. Are the study researchers planning on making the data openly available? Is it going to be cash payments, or will it be some sort of debit card where the researchers can track whether people are spending money at grocery stores, or at casinos?

Does GHC still come with a copy of GCC and Perl? Hugs is pretty small:

Just to make sure that we aren't all talking past each other...

1. I assume the FBI is investigating the hack itself (who did it, etc.). Citation?

2. I assume the SEC is investigating the suspicious timing the executives who were selling stock before the announcement. I'd also assume it could turn into a criminal investigation. Cite?

3. The class action suit is a civil action asserting that Equifax was negligent (that's what the Bloomberg article that these comments are currently pointing to is about).

4. There could be criminal negligence in securing their networks. It seems like that could be either of a Federal or state issue. Anyone know if this investigation would take place with the FBI, or if there is another federal agency which would take the lead on that?

You are right. The sheriff that covers Ryegate, MT commutes in every day from New York City, and the school bus drivers commute from Seattle, likewise the mailman commutes in from D.C., and the garbage man from San Francisco.

Interesting. I'd like to learn more about this. Any pointers to how other languages and cultures don't distinguish between math and science? Does it apply to other things like the difference between induction and deduction as well?

Here's an utterly trivial question. Do most people working on computational problems like this consider themselves mathematicians or scientists?

The Strang book: "Introduction to Linear Algebra" does seem to have quite a few "high quality" 1-star reviews. They mostly seem to cluster around this book not being good for a linear algebra introduction, for someone new to the field. Typical comments:

"It seems the reviewers who think this book is wonderful for non-math majors are math majors!"

https://www.amazon.com/Introduction-Linear-Algebra-Gilbert-S...

...I of course expect that any popular book will have 1 star reviews, especially by people who had a hard time with the material. Anyone have thoughts whether the Strang book is better as a supplement to other texts in coming up to speed on Linear Algebra? Other book recommendations?

Just some clarification for those readers not in the U.S.. You as the defendant do not have to select have your case tried by a jury. You can select to have a bench trial instead. There is a presumption of innocence for the defendant, so the prosecutor has to show "beyond a reasonable doubt" that the defendant committed the crime in question. Juries find defendants not guilty more often then judges do. So if you want a society that better reflects the maxim, "better 10 guilty men go free, than 1 innocent man go to prison", then juries are empirically better.

Is there a way to find out how much Foxconn pays in U.S. taxes right now? Or how much revenue they earn in the U.S.? If Apple has Foxconn make phones in Taiwan, and Apple then ships phones to the U.S., then Foxconn doesn't pay any taxes to the U.S. on those transactions, right? Only Apple would right? If Foxconn doesn't pay any tax to the U.S. right now (???), and they build a factory in the U.S. and don't pay any taxes in the future, then it is a wash (except for now the U.S. employees would be paying income tax, etc.). Or am I missing a piece of the puzzle? (As in, maybe Foxconn is currently paying a lot in U.S. taxes from whatever operations they have in the U.S. currently?)

>If you were to tell a non-HNer that Kayak, Booking, Priceline, CheapFlights, OpenTable, and other large websites are worth 100B combined, I don't think they would even blink an eye.

...is that because you don't think non-HNer's don't have an appreciation for how much something like Walmart is worth (~$250B)? Or because you think they believe that $100B is a reasonable valuation?

>Really is fascinating how different perspectives can be.

My personal experience is that "most people" wouldn't recognize that Kayak, Booking, CheapFlights, and OpenTable were businesses / websites, let alone use them.

Anyone have success stories to share? I've tried adding various sites to my hosts file. But I seem to lapse after a while, since I can restore the file anytime I want to. Any negative reinforcement ideas? Like an annoying sound (baby shrieking?) played or an electrical shock when browsing to particular sites? Any methods to prevent yourself from uninstalling things like that though?

Any ideas on how long it might take to get over any "withdrawl" period? Like you only need to "tough it out" for a month, and then it becomes more manageable?

>1. First America stops being world police.

Yes, how do we do this? I'd like to see us declare victory, and remove our troops from South Korea, Japan, Germany, the rest of Europe, the Middle East, and everywhere else. The UK did essentially this over the course of the 20th century. Is there any way to accelerate the process without world wars?

Does anyone have examples of groups working "together" that share one common interest, and are opposed on many other fronts?

Anyone have stats on rates of alcohol use over time, compared to other medications? For example, maybe people are using anti-depressants instead of medicating themselves with alcohol?

>There are very few projects without Py3 support, and most you'll find without Py3 support is because the project has been dead for quite some time.

One notable exception is FreeCAD for anyone who is looking to jump into a project to help with the transition from python 2 to 3.

>...it's so full of little bugs and crashes it's not really usable in my mind. I'm using the version from Debian unstable.

Ever try it on another platform or build? I've been learning FreeCAD for the past few months, and while have certainly come across "quirks" (like certain boolean operations not working quite right, the polar array feature in the Draft workbench working with everything I throw at it, but the polar array feature on the Part Design workbench choking on somethings, etc.). I've never had it crash. I've been using the "stock" v0.16 x64 build on Windows 10. It could be that since I'm just a CAD newbie, that I'm not exercising it hard.

That sounds like it is true for western countries, but China has a lot of nuclear power coming online, and what are the attitudes in India?

Anyone know more about India's nuclear story? At one time they were focusing on thorium. I wonder what we could do to spur on a little more competition with China.
