You are missing something (but don't worry, it is good to brainstorm like this).

At maximum speed (maximum energy storage) you want every part of the flywheel to be about to break. By introducing a non-structural material (liquid water), you have added mass but not the strength to get to higher speeds.

Imagine filling a bucket with water and spinning it around your body. All of the force to keep the bucket from flying away has to be held by the handle of the bucket. A better bucket flywheel would be all handle... Hopefully someone else can give you a better analogy.
I agree. The original article reads very much like a Whig history of the medieval peroid.
OK so he takes the Fourier transform of a non-periodic array of delta functions with the delta functions being at the prime positions, and notices peaks at inverse separations of 2, 6, etc. There’s neither X-ray diffraction, chemistry, or any real math here. Garbage.
HNers interested in this topic are liable to be interested in SlateStarCodex's treatment of it: http://slatestarcodex.com/2014/01/05/marijuana-much-more-tha... .

tl;dr; according to the author's "Irresponsible Utilitarian Analysis," the statistically dominant factor in whether widely-legalized marijuana would be a net benefit or harm to society is its impact on driving. Since cars are, for most of us, the most dangerous thing in our lives, this probably makes a decent amount of sense.
But in the opening post, John Carmack said that is what Steve would do: "It was often frustrating, because he could talk, with complete confidence, about things he was just plain wrong about, like the price of memory for video cards and the amount of system bandwidth exploitable by the AltiVec extensions."

Alan is very smart and was a prodigy, but I think he put up with Steve Jobs' eccentricity to a larger extent than our eccentricity because he could influence people and got a few things right. (Although Alan has been said to call out CEOs for incompetence.) Murray Rothbard (economist) said all the billionaires he ever met were crazy. Probably because their colleagues and employees would put up with a lot of stuff they would never let anyone else get away with.

Unlike food, film will survive being defrosted and refrozen, as long as it's kept dry.

Film doesn't even need to be cold-stored unless you're wanting to store it long term. It should last until the expiry date (usually a year or two) at room temperature without any ill effects.
All history is conjecture. The primary sources relating to 17th century Angola exist, they're just sparse. I just told you that Queen Nzinga sent letters to the King of Portugal, for instance. If you're genuinely interested in this, John Thornton and Linda Heywood both give good surveys of what sources are available and what they can tell us.

I work on early modern Britain, Portugal, and their colonies.
Sure, it would be a net gain. I am just saying replacing 2% of fossil fuel production with wind/solar seems a lot easier than getting 300+ million people to do something else to save under 2% of electricity usage.

Socially, improving commuting infrastructure so people waste less gas would easily have a larger benefit and you are not going to fight nearly as hard.

Etc etc, this might be top 50 but it's not a top 10 and it's hard.

"Free will without consequences" is as nonsensical as "rights without duties".
I am guessing it means that binaries native to the OS has only one instruction set which the kernel JITs onto the local CPU. That ISA might be some byte-code, or else are in a well known ISA (such as x64) which gets translated at need.

Another possibility is that the kernel supports multiple source ISAs and translates them at need.

Since many depictions of Mickey are registered as various trademarks of the Disney conglomerate, things will basically shift from copyright to trademark law and they will be less able to say “you shall not pass” but they can definitely still make your life hell if you cross them.

Edit: I forgot to mention that I suspect that Disney started using their new pre-movie intro motion graphics that are heavily derived from steamboat willie as a bit of a hedge, since they get a reasonably strong defence from the complete inclusion of the opening sequence of steamboat willie against potentially confusing trademark infringement. It’s also a sneaky way to get a new copyright covered variant of their original material.
I have the same complaint. I couldn't think of a polite way to put it, so this won't be polite, but whenever someone compares their algorithm with a poor version of a competing technique, it makes me question their integrity and results.

CeresImaging.net | Scientific Tools Python Engineer | FULL-TIME | Oakland / Bay Area | ONSITE

We're looking for a software engineer (or code-savvy scientist) to work on developing, maintaining and improving our image processing and scientific tools codebase: python code (including lots of scipy, numpy, geopandas and rasterio) used daily by our team of scientists and GIS analysts.

Ceres Imaging designs and builds multi-spectral camera systems. We fly them over farms and orchards, and process and interpret the imagery, allowing us to detect plant stress, overwatering, under-watering and early indicators of harmful pests. Farmers use this information to manage their resources, conserving water and avoiding unnecessary over-application of fertilizers and pesticides.

Completely agree with the point about not hiring based on specific language experience, but I took the phrase "make sure you’ve included the same language as the job description if at all possible" to mean "use similar terms and phrasing as those used in the job description." I think in that context, the advice can be helpful.
Nope, not joking. I just know that euro machines are way slower than what we have in NA.
All of the first part of your message constitutes much of the rationale behind Signal Protocol, which is asynchronous, does not assume participants are online at the same time, and does not involve you handing secret keys to a server. But, of course, Signal isn't the only way to accomplish forward secrecy.

Am I "implying" that forward secrecy is required for message security? No, I'm saying it directly.
That might be true in general, but for this particular case, it would seem like it'd be irresponsible to disclose without giving advanced warning to the email client developers. We're talking about giving the chance for journalists, political activists, etc. to be protected from this bug via a typical, routine software update without having to know about the bug before their potential attackers. If the vulnerability is still on, it's now a race on who'll learn the news first, the potential attackers to exploit it or the potential victims to avoid it.

Meanwhile a 2-ton giant marsupial in Australia had no reason to fear and evade the new bipedal neighbors, or so it thought...

This is categorically false. Might be true for small startups, but most established companies do not ask a lot of engineers during crunch time.
This seems a little silly - it's an irritation, but it's not big enough to amount to anything really. If anything, it hurts lower-end positions more than any other, since it's a flat head tax. If you're counting the beans closely, it starts to make sense to hire 9 people with the salary you might have allotted to 10, and so forth.

All this would really seem to do is piss off Amazon and Microsoft and the other big players, which is kind of cutting off your nose to spite your face.
My issue with bundling of news specifically is that it becomes bland and generic. The bundler starts trying to guess what I want -- which defeats the purpose of why I read the news. I subscribe to the NY Times and the WSJ separately precisely because I want multiple angles on the same (and different) events.

Besides, bundling usually means someone down the pipeline -- usially the producers -- are getting royally screwed.

Some things I went through as a step parent....

- the first time I took my younger now stepson to my house just to hang out with him, I thought the weekend went well and as soon as I took him back home to my now-wife he started crying. I had no idea what I had done wrong. A few minutes later I realized he was crying because he was upset that his father left him and didn't show him that kind of attention. Years later, we are close as can be, but there is still a feeling of abandonment.

- my wife had a hard time adjusting to the three of us (me and my two step sons) sometimes just hanging out and she felt like the third wheel. She was happy that we got along but she was so use to it being just the three of them.

- No matter how much they try to talk bad about thier father, I try to tell them just be better and when they grow up, remember how they felt and do better. I never say anything negative.

> Perl 5 was abandoned

It's all relative. Perl 5 is more active now than at any time in its history.

Python has expanded 20x in the last 20 years. So Python has in relative terms eaten Perl's proverbial lunch and overshadows Perl so much that it's easy to think Perl just died. But it's actually successfully scavenging and growing nicely in the shadows despite the 20 year long drumbeat of pronouncements of its death.

From my perspective it does look like extending Perl 5's core is painful but that hasn't stopped it growing to a half million lines of change a year (and many millions a year in the upper reaches of the CPAN river and tens of millions further downstream) and folk writing ever more powerful pan ecosystem tools as, eg, described in this report from a couple days ago:

http://blogs.perl.org/users/preaction/2018/05/cpan-testers-a...

(That all said, I'm personally more focused on Perl 6 which is a new ball game even while it's also an extension of the old one in the sense that it cohabits in the same ecosystem and culture.)
Assuming you have Anisometropia (difference in prescription strength between the two eyes), this is only half the deal.

Synthetic fabrics have a surface that bacteria attach to really easily. It's one reason gym clothes pick up smells that no amount of washing can get rid of.

Merino is so antimicrobial that if you hang dry merino training clothes that are soaked in sweat they will smell fresh.

Statistically the poor and minorities get treated worse with harsher sentences for the same offense. Don't you think it's strange that it was all about being "tough on crime" when drugs were happening in the inner city but it's all about "treating drug abuse as a disease" when it's illegal use of prescription drugs in the burbs? Drug dealers in the inner city get locked up. Doctors who over prescribe because they get "marketing assistance" may get a slap on the wrist if that.
(IANAL) It depends also on the specifics of the law. For example, in Finland the copyright protects only the actual works, not any "idealized" representations such as the "character". That means that you are free to produce your own work with a character that resembles Mickey Mouse and own a copyright for that, as long as you can reasonably show that you haven't copied any Disney's copyrighted work verbatim. The only weapon Disney has against that is the trademark law so if you do it non-commercially (or commercially in a way that doesn't violate trademarks, whatever that means), you are free to do so. Not that I recommend doing so, because that's asking for trouble. But there's this Finnish artist, Kaj Stenvall, who does exactly that with his Donald Duck series: https://www.google.com/search?q=kaj+stenvall&client=firefox-...

I think the saddest part of this is that we've managed, as a species, to come up with such a resilient and durable material, and yet we've come to simply waste it in great quantities, treating it like it's useless rubbish.

The disparity is even more striking if you look at the figures per capita. The US generates almost 3 times as much waste per capital as China.

China has 4.25x as much 'capita' as the US, so in absolute terms they produce more. I'll grant that the disparity is "more striking" if you phrase it in a way that obscures the full details.

In fairness, you're right that exporting garbage is bad, and we all need to be producing less of it.
