Many companies in Switzerland force their workers to work longer (between 5 and 10 %) to compensate the so called "Franken Schock". As they don't have strong regulations on working time (compared to Germany for example) this is not a problem. They also started to pay some of their workforce in EUR instead of CHF (this happens to new employees and especially for people crossing boards to work there).
This demonstration is often available in hands-on science museums. The problem I have is that it's just a demonstration for one particular right-angled triangle, not a proof in any sense.

See http://math.stackexchange.com/questions/675522/whats-the-int... for examples of real proofs with insight.
I had the same thoughts. Why would a company like HashRocket use such an example? Or did they just not know? I don't know.

> The passive (gravity fed) cooling system on the first reactor to melt had it's valve's almost closed when they lost power. Seems like a bad design to even have valves on it but I'm not a Nuclear Engineer.

It wasn't a great design. But that's what happens when you take reactors that were built before Chernobyl, were optimized for producing material suitable for nuclear bombs instead of safety, and then run them long past their designed lifespan.

More or less, these reactors should have been retired long ago, and replaced with more modern designs.

LA Fitness has this one down to a fine art. You have to send a form, -by certified mail- to an address. They will not let you cancel in person, on the phone, or online.

That's the old bootstrap vs VC money argument, but bootstrapping doesn't work for a lot of business.

I don't get what's the issue with that statement. Until you give up on the idea, you didn't fail. What other interpretation do you have in mind? It's one of those cliche way of saying failing is just the beginning of success.

The thing that convinces me is her determination. She worked as cleaner before starting the business, and understood some of the pain. She probably overlooked at the issue and probably overconfident like the article cited, but someone who was willing to cover cleaner to apologize for cancellation on Thanksgiving? That's very good for her (but unable to prioritize some critical negativity in the algorithm? that's just sad). Without knowing the full story (we are just hearing fragments from allegedly ex-Homejoy employees), I think the business model is not profitable. Maybe doing cheap is really hard, and doing fancy and professional is the only way out.

When you consider that a nuclear plant costs billions of USD and that billions of USD of damage has been done, the $500,000 upgrade to the generators is a slam dunk. Also based on recent projections, the probability of a tsunami event of that severity was 80% for the next few decades, so it is a no brainer -- particularly when you consider that the nuclear industry worldwide has been set back 20 or 40 years at least by this incident.

The NRC has had modernization plans at U.S. reactors that have spent much more than this. For instance the hydrogen bubble formation in that kind of BWR was well known here and reactors in the U.S. have had features added (dependent on a power source) that would get rid of it.
Racism against Asians in North America is really puzzling. It is excessively common to hear female acquaintances, even asian ones, say that they would never date an asian guy. Compound this with comments that belittle asians in movies, TV shows and in just about every conversation, I sometimes wonder why they keep so quiet. Then I remember that racism is a complex and delicate question, and that our society is still incapable of dealing with these issues in 2015.

ps: As a child of bill 101, I do not really understand what you meant by that comment about French in Quebec.
Thermoelectric cooling ([1]) can reach such temperatures, which will not require any gas consumables. However, it could be more energy-efficient to cool with CO2. I have not done math for that.

> There are somewhat successful languages out there where sending a message to a null object doesn't do anything.

The reasons that is defensible in message passing systems is because such systems are basically recapitulations of computer networks, and object nullity is equivalent to a network partition. That's the kind of failure mode that you handle in the policy layer, which is above the runtime layer in an application system just as it would be above the network layer in a distributed system.
Kind of an interesting history:

There's a very good chance I'll get downvoted for this, but what the heck:

> As a male WASP, why would you bother with what a homeless person thinks of you? I too ignore the angry vitrolic ones. They hate me too, though they may lack epithets for me. It's a pointless unwinnable argument, and you'll never look like the good guy, yelling at a homeless person

The answer is in the original comment

>> If Asians sometimes remain silent in the face of racism, and if some seem to work unusually hard in the face of this difficult history, it is not because they want to be part of a “model minority” but because they have often had no other choice.

Asian-Americans are told by others all their life that it's uncouth to speak out about injustices that happen to them. Ironically, the first comment on an article that discusses this point mentions one of these injustices, and the first reply is a comment that suggests that they should remain silent about it instead.

It's one thing to remain silent as a conscious decision not to want to look like the "bad guy", but it's an entirely different thing to remain silent as a conscious (or unconscious) reaction to the societal role that you've been conditioned to.
People often forget that systemic racism against Asian Americans is also racism. That's part of the point. That you can do everything right and have things go reasonably well, but have it all taken away from you because of the color of your skin.

Like the physicist who was innocent but had his family dragged through an espionage trial because the officials didn't even bother to consult experts in the field.

As opposed to this one :-)

Well it has some good points, I particularly resonate with the assertion that if you don't want to be like the CEO when you "grow up" you probably won't mesh well with the culture.

The other point was that if you are a leader, you are the culture. Simply put, people will consciously and unconsciously follow your cues for how they should behave in "cultural" situations.
IMO equity is not the only consideration -- there may be a value to workplace diversity itself, and #1 adds some transparency to the issue. The #2, if you look at it, actually suggests solutions where gender is invisible, rather than push for preference for women over equally-qualified men. #5 sounds non-neutral, but really could be implemented in neutral manner -- what it says is that women have a harder time finding mentors. Surely some men are in that category too.

Some might advise you to keep pushing her and pushing her because "we need more women in STEM" and all that. I would advise you to just let her be. We like to teach our children that they can be anything they want to be when they grow up. So... maybe she doesn't want to be a software developer.

"We need more women in STEM... even if we have to drag them kicking and screaming", said no one ever.

I'm not saying forego funding, but what I am saying is if VCs took a longer view and didn't throw tons of money at companies that haven't proven the need for it, expecting unrealistic returns, we would probably have a much higher success rate in SV startups than is the case today.

Even though funding was required in the businesses you listed, none of them would've grown to the size they are unless the market demanded it.

I know this sounds obvious, but it seems to be a counter point to the behavior I see in SV startup stories.

Probably, and for far more than just cleaning. For example, tutoring companies do all sorts of ridiculous things to try to prevent "disintermediation," but they take such massive cuts of a tutor's fees that a compatible student and tutor can split the difference (i.e. each take half of the company's 20% cut) and both benefit. Why on earth wouldn't they?

I'm not sure if that was necessarily racism though. I think because China is now seen more and more as an enemy and the professor was born in China, maybe that's why. Not excusing the the FBI, just questioning whether racism was at play. What if it had been a white Russian scientist? Would it have been different?

Can't wait to read the new Go book! Congrats on the launch guys! <3
I guess my point of confusion is that it seems to me like angry homeless people using slurs are not an injustice visited upon Asian Americans, but rather garden variety obnoxious people who in my experience hate everyone, not just Asian Americans.

I understand Asian Americans face systemic racism; it's just that the particular example at hand seems like something else.

My original parent is welcome to say things back if they like. But it just seems pointless, no matter what nationality you are.

Anyway, I know I'm on the "wrong" side of this discussion for HN, but that doesn't make me less confused.
You mean we never think about all of those guys that actually did start a nuclear war?
I don't know Ron Conway, have never heard anything but good things about him. I was expecting the published email to be more about what he thought people should vote, a plea to certain sensibilities which he believes in.

Note: I also don't live in the US (and therefore, clearly not in the bay area) and therefore have no horse in this election race.

It's a bit disheartening to see a simple list of the items/people to be voted for, and how someone should vote.
No explanation, not an "I'm voting this way and hope you do to", but rather what reads as more of a command of the way the reader should vote.

Having never met Ron Conway, I'm not going to hold this against him, like I said, I've heard great things, and am saddened to see Pando/Paul gloriously defaming him in the intro. I guess that's what I expect of Paull Carr, I haven't read anything of his in ages, and I guess I remember why now.
Why wouldn't it? Kids are taught from childhood what their gender is supposed to like. If we got rid of that, surely far more non-men would be in tech.

In real world, if your regular cleaner calls in sick, you don't pay for that visit. If you really need some cleaning done you talk to him to come a few days before the usual scheduled date. It is a 1:1 relationship and often with the cleaner in the stronger position.

Apps like Handy want to invert that, but in the case of Handy they basically failed to provide the consistent quality and a critical mass of cleaner to offset people reluctance to engage with cleaners like this. This lead to the kind of frustration the parent describe. The real loss for Handy is not the cancellation or even the loss of that customer for good, the real loss is that they lost the recommendation of that customer and recommendation is the main way your currently chose a cleaner.

I grew up on a CoCo3; loved that thing as well :) OS-9 Level II was where I first learned a Unix-like OS (on a tiny 6809 machine!) OS-9 Level II was truly a remarkable achievement for such a tiny machine: multi-tasking, windowing, and more. Dungeons of Daggorath was also an epic game. Basic09 was an interesting Basic-dialect that provided more structural programing to the normal sprawling Basic program. And of course who could forget Rainbow Magazine.

Guilty as charged. But those cold dispassionate observations can inject casual bias as well as heated comments. That was what was galling. The 'oh you know how the domestic help is always stealing stuff' injected casually was more than my bs-meter could handle.
Everyone is scared of deflation, but is completely comfortable with the rapid drop in the price of electronic goods over the last few decades.

I'm simplifying a bit. The traditional theories that warn against deflation are concerned about consumers delaying spending in the hope of waiting for even cheaper prices. This delay theoretically forces the economy to grind to a halt. I think most people accept now that this is an unlikely outcome.

Now when Central Banks worry about deflation they are concerned that it might trigger a fall in real incomes, while debt remains at the same level, meaning people aren't able to pay back their debts. In our debt addicted economies, this is a real risk.
This is pretty huge. The last major break thru was getting superconductivity in Y1B2C3O at liquid nitrogen temperatures (-200 C) back in the 1980s. I worked in a lab with the discoverer of this phenomena, Dr. Paul Chu.

While -70 is still damn cold, it should be achievable a lot more cheaply than having to cool things with LN2, so hopefully-- cross our fingers-- this will lead to the breakout of superconductivity into broad industrial use (and maybe the mainstream consumer market) that people have sought for decades.

BTW- while in that lab I used a variation of the meissner effect to design a memory circuit that was theoretically buildable at the time- static RAM that was superconducting. (and basically, the essentials of a transistor were there so logic gates could be built from super conductors, that was the thought experiment I was doing.)

Since heat is a major concern in CPUs, the ability to be superconducting (and thus producing no heat) would be a huge boon for computation. Of course initially this wold be at scales much larger than current lithography and thus only for specialized applications. But who knows.

With effort the cost of keeping a CPU at -70 should come down dramatically the way battery capacity per dollar has... or dare we hope the way flash density has.

> I sometimes wonder why they keep so quiet.

A big part of it is being consistently dismissed or more often punished for speaking up.

Because of the myth that racism "doesn't happen" in the West, or that racism "doesn't happen" against Asian-Americans, if you try to speak up about it, one of two things will happen:

1. You'll be told that you should just rise above it[0], that you're imagining it, or (my personal favorite) that it's "not really racism" because $REASON.

2. You'll face outright retaliation for bringing it to light, and thereby forcing people to face an uncomfortable truth

After a while, the fear of these reactions gets internalized, and people decide that it's safer just to remain silent.

EDIT Ironically, as I'm writing this comment, this pattern is already playing out in the sibling comments, with more than one person telling OP that he should just ignore it (or in other words, "be better than that"). Which misses the whole point of the story.

[0] and this is how the role of the "model minority" is actually used as a weapon
Yes, let's make it clear it isn't a first order effect but likely a third or fourth order effect. E.g. They grew up in different areas of the country, one part having higher living standard expectations, and if you get to the bottom of it, it had to do with race at some point decades ago.
There's a cool exhibit in the Oakland Museum of California about proposals for the shape of the eastern border of California!

Interestingly, some of the motivations for the proposals did involve something like gerrymandering, in terms of arguments about how many Mormons who had emigrated to the west would end up being included in California's territory.

Another interesting thing about the California-Nevada border that ended up getting adopted is where the northwest line turns north (where the bend is): it's inside of Lake Tahoe. That makes it a lot easier to remember!
People keep saying the quality was great. It was pretty good - for a live stream. It still sucked compared to cable or satellite HDTV. NFL games are really the only reason I get DirectTV, and a blurry, pixelated stream isn't going to change that, even if it is slightly less compressed than other streams. (It didn't buffer much at all, I'll give it that.)

Or was my internet provider (Comcast) messing with it?
Megatsunamis are caused by large volumetric displacements of water resulting from massive amounts of earth entering the water. The tsunami that caused the Fukushima disaster was not a megatsunami - it was caused by thrust faulting resulting in underwater displacement rather than the megatsunami mechanism discussed above.

The analogy here is splashing your hand into water (megatsunami) versus moving your hand underwater.

I suggest that you let go of this incident as it is not worth it to get all worked up over a casual insult especially from a homeless person as you'd be dragged into their mud and they'll win by experience.

I recall some time ago I was walking down the street when a panhandler approached me and asked me for money and as usual I ignored him and when he noticed that I paid no attention to his request, he told me he hopes to see me burned alive to which I replied with a fake smile and just went on thinking how he could thought that insulting me would win me over and make me change my mind and pay him, and that's it. 15 seconds later, I had better things to preoccupy my mind with end of story.
I'm not sure why you were downvoted for a reasonable post citing original sources (I upvoted you to try to correct that).

How does Star Wars prepare you do be a programmer, and watching a princess movies does not? I don't recall any programming scenes in Star Wars? And all those movies are made with computers. Girls tend to be encouraged to lots of creative activity which could also come in handy with computer jobs. They also do well in maths at schools (better than boys, apparently).

Can you cite any studies that support your claim?
That really sucks, dude. I'm sorry your coworkers are such assholes. My situation was similar. I came to the US in '94 when I was 3 years old. Being one of very few Asian kids in mostly White schools was not fun. But thankfully, I haven't personally experienced any overt racism since graduating from high school.

Figuring that out is kind of integral to Handy's business model. they're essentially playing matchmaker between customer and service provider, which means their business begins and ends with customer service.

If you pay for Bob to come over and clean your kitchen because you know Bob does great work, it's perfectly reasonable for me to call you up and say, "Bob's sick today, can I send Jed over instead?" But it's also perfectly reasonable for you to say "no, so cancel my appointment for today." It is not reasonable for me to charge you a cancellation fee under that scenario.
Sorry if I come off a bit crass. What you have is still a major improvement over people dumping all of projects like zlib and libpng in just to load in files.

It's just that code complexity is probably my biggest pet peeve in programming. People often underestimate what a boon it is to avoid library dependencies. I've had so many code contributions from Windows people because all it takes to build any of my software is: "run the TDM/GCC installer, then run mingw32-make" ... the Linux/BSD mindset of "just apt-get/pkg install the dev library" doesn't work on the platform that most users and developers are on, sadly.

Whereas even I usually give up trying to build OSS that has a Windows port with a dozen dependencies.

So keep up the good work, and don't be afraid to gut some of those excess, unused functions in your own project :D
