The interesting thing to me was the the two supercritical experiments that led to imminent death were both with the same core, dubbed by the research team the "demon core."

Daghlian was experimenting with the plutonium core to determine exactly how close the core was to supercriticality by stacking bricks of tungsten carbide (a neutron reflector about twice the density of steel.) He slipped and one of the bricks fell directly onto the core. Daghlian said later he knew at that moment he was dead. He threw the brick off the core, but it was too late. The resulting neutron burst killed him a few weeks later.

Interestingly, this same core also caused the death of a second professor, Loius Slotin. Slotin was attempting to perform the same task, determining the point of supercriticality, but using a different approach.

In this case a beryllium sphere(!), another neutron reflector, cut into two hemispheres were slowly lowered together, and the resulting neutron levels were measured.

Slotin was famously reckless, and in his insanity, he developed the apparatus such that the only thing keeping the two hemispheres from completely joining and producing an immediate reaction was a flat head screwdriver he slowly twisted. Enrico Fermi said several times "He's already dead. It's only a matter of whether others die with him."

Sure enough, one day Slotin slipped, the core went briefly supercritical, and the massive dose of radiation killed him.

A superstition developed around the core, and although it was originally slated for wartime testing, the team left it on the shelf until after the war, when it was eventually detonated in a test at Bikini Atoll.

This is not even correct. Endangered species are much safer in the US than Africa, because nobody is eating them for survival or poaching them to sell to the Chinese. Strong institutions and better-than-sustenance jobs are how to protect wildlife.

A few books I read for fun this year:

- Armada: Ernest Cline - Very disappointing and predictable

- Library of Souls: Ransom Riggs - Easy but engrossing book

- Ruby Under a Microscope: Pat Shaughnessy - I find his style of explaining things very accessible

- Being Mortal: Medicine and What Matters in the End: Atul Gawande - It's a hard subject to think about but helped me to understand that prolonging life and continuing treatment shouldn't necessarily be the end goal for every case.

- Go in Action: William Kennedy - A must if you're learning Go lang
The vast majority of defects groups like intelligence agencies are exploiting are not going to be intentionally-placed backdoors - they're going to be typical vulnerabilities discovered the normal way, just by an organization with immense resources and no motivation to share.

So the bottom-line is that it comes down to how much you trust the people that made the software. Is it a very high quality vendor? Is it a very high quality open-source project?

The nice thing about open-source software is that you have a much better ability to evaluate this from the inside. Get on mailing lists, poke around trackers, and see how they usually deal with security disclosures. Do they even have a formal program to do so? I'm not sure that OpenVPN does, although a lot of distros watch that carefully.

Both lions and humans (like most, or all, animals) are sentient.

You may be referring to some concept of intelligent self-awareness, but you need to be more clear as to what it is to evaluate whether its a real difference between humans and lions; lots of animals have demonstrable self-awareness of various forms.

I agree that the human condition is more important, but I don't think your explanation of why holds up.
You didn't see any horizon effect? People didn't become more likely to "cheat" as the game and the value of their reputation approached an end?
Since it's now clear that "many eyes makes all bugs shallow" is patently false, the MO for said agencies to compromise OSS projects is to play the long game of making numerous benign commits, becoming trusted, then committing subtly compromised code.

This would be much easier than compromising specific algorithms or KE protocols. Cheap, too. All it takes is plenty of patience.
I get the feeling you are underestimating how difficult of a decision this is.

If you really care about doing the right thing down the line, I recommend thinking very long and very hard about it because, down the line if you do succeed, the time you have to take the decision will come and you will not be expecting it by then. Underestimating the situation is a sure-fire way to fail your own expectations.

One of the big things that drew me to amazon's platform was their 'ASAP' streaming. It wasted my bandwidth to begin streaming all the stuff I might be about to open and as a result it seemed seamless.

If Netflix can make my film stream at a high resolution faster and buffer less, over time I'll notice the buffering more on other platforms and just use Netflix instead.
One word - isolation.

One issue with using your system's packaging system is that a lot of system utilities are written in Python which makes it harder to play around with new versions, bleeding edge libs, etc.
I've been dragging my heels on this for a long time, but I'm finally starting to take the plunge into 3.

I think for any greenfield project, there's very little reason to use CPython 2 anymore. If you want performance, use PyPy. If you want features, use CPython 3. From now on, that's the philosophy I'm following whenever I write something new.
>Compounding the injustice, she said, is the wage gap. Federal data shows women in the United States earn about 79 cents for every dollar paid to men. “It’s a double whammy,” Menin said

Can we put this meme to rest already? That gap is mostly attributed to career choices that lead to less pay.
Assuming that, as implied, most of these goods are purely substitutable with no physical difference but in "gender-specific packaging," then one could actually interpret this as the capitalists (inadvertently or not) pushing consumers towards deconstructing traditional gender roles through their mark-up pricing. We can thus observe the profit motive serving a positive social function, though YMMV depending on ideological preconceptions.
I don't think it is. But that said, I guess perhaps we as human beings are biased towards our species and/or empathize better with the human condition.
> Those 10 lines can be 10 lines of assembly, 10 lines of c++ or 10 lines of haskell.

I seriously doubt the validity of this. 10 lines of assembly is usually reasonably clear-cut what is about.

10 lines of Haskell can take hours of mindfuck trying to peer through the functor and monad operators, trying to work out which operation does what and which operator takes precedence where. And then you need to start worrying about which data-type are you actually working on. And how does that type implement lift and bind. Etc etc.

Basically 10 seems like a BS number taken out of thin air, because it looks good in a base 0x0a number-system.
Discrimination? Please... Can we not use this word to describe this phenomena?
The undertone of the study and article make this situation sound like there's something cynical happening.
It's just supply and demand.

I am a 5'11" male with medium build. Whenever I try to get my shoes sized 10-11, I consistently pay 10-15 bucks more than someone with shoe size 7 or 13.
I also have to pay more on cloths because people who can wear xxs or xxl usually get swoop in on good deal during sales. Medium or large are always sold out. Does this sound like "discrimination"?
It absolutely does not; you need to increase your reading comprehension skills.

Articles like this promote a very absurd notion that there is a vast conspiracy to actively discriminate against women. While there is, of course, real discrimination against women, this simply isn't one of them.

The only discrimination going on here is that men are more discriminant on price than women are with broad categories of items. I work with retail data, and I know this is 100% true. Items marketed towards men in the "Consumables" category (deodorant, razors, shampoo, etc) are priced lower than their female counterparts because decades of scientific analysis has shown that men are more likely to shop for these particular products based on price than women are.

In economic terms, depending on the category, men and women have different price elasticity curves.

An interesting twist on this is that certain Men's products within the "Consumables" category are at high price points due to the data showing their respective consumer group to be far less price sensitive, especially with the 18-25 male demographic with hair care products.

This is all data and algorithms talking, not actual discrimination.

Anyone with a son can also point out exactly why boy's underwear costs more than girl's underwear: boys get very excited about underwear with characters on it, so parents are less price sensitive on those products. But according to this story, this is just another form of evil discrimination towards boys wearing underroos.

According to Gillette, there's a difference between men's and women's razors and razor blades. Whether it's just marketing copy or it's actually the truth, I couldn't tell you. But this is how they justify the price difference: http://www.gillettevenus.com/en-us/how-to-shave/hair-removal...
One word: overreach
>No, you've misread the packaging.

It appears I have actually. Thanks for pointing this out! That removes a lot of my issue with the article with that issue, because it didn't exist to begin with. Just my own misreading. :)

If I'm allowed to excuse why I overlooked that 4 - I'd blame my familiarity with the male packaging. I didn't even notice the 4 when looking for numbers because it didn't have words next to it! At this point I'd be more offended that they think the word "cartridge" is too difficult for women and use a picture of the blade instead, as if they're children.

That has been open secret since the early 90s I think.
Then of course APL is king since a 10 line APL program is huge. But that doesn't really bear it given APL's reputation as a write only language.

Abstraction also has a cost. You can cram a lot into 10 lines, but if you have to think a long time about the most elegant way to do that, you might not be winning in productivity.
> Containers are no vm's

A container is whatever you want it to be. Single process? Sure. Full OS? Sure. Somewhere in between? Sure.

Containers are not new technology, and they were not invented by Docker or Linux. An artificially-constrained view of what a container is (or should be) that's driven by one tool's marketing (Docker) isn't helpful.
Have you tried any of the other smartwatches? I ask because I really really like my LG G Watch R. The specific use case you mention - I don't use Hue, but I have a Roku remote installed on the watch that I use all the time. It's two taps to get to the remote. Much faster than pulling out my phone. I also love that it looks like a real watch. Most people that see it assume that it is just a regular watch, unless I start talking to it. Maybe I just have poor taste but I really don't like the look of the iWatch - it looks like they shrunk an iPhone and strapped it to a wrist band. Which I guess is what it's supposed to look like but not really my taste, I guess.

Not trying to bash Apple here I almost always recommend Apple to friends and family even though I mostly don't use it myself, but I do think there are much better smart watches available than the iWatch.

Er... what? Hierarchical is the very definition of "scales well". That's what you want to do when you have many instances that all need to talk to each other. Distributed means combinatorial explosion. It's... like secondary-school-level graph theory/probability.

Distributed is what you want to have for a) robustness (because redundancy means the work can be redirected to agents that are still alive) and b) adaptability (because system can restructure itself locally without the need to coordinate with the entirety of it).

Of course you want to apply those two recursively, e.g. hierarchies that encompass many peers at each level, etc., but that doesn't change the point. Frankly, the whole field of distributed computing is one big proof that hierarchies are good and desirable.

As part of the market research for a previous startup, I talked with plenty of recruiters who would love for their to be a market for software talent agents. If you're curious why such a market doesn't exist, read Aline Lerner's article "Why talent agents for engineers don't exist":

http://blog.alinelerner.com/why-talent-agents-for-engineers-...

tl;dr: Agents exist when it's hard to get a job. It is not hard to get a job in software right now. If your company mistreats you, you figure that out pretty quickly and move on to a company that doesn't mistreat you. There's no need to pay anyone to make that happen; in fact, you can get paid a significant amount more just by asking around.

You hear about stories of startup employees getting screwed because the software engineering labor market (particularly for startups) is expanding rapidly now, and so there are a large number of employees who have no experience in the industry. These people are easy prey for a good salesman who wants to make their sham company seem like one of the winning startups. But it takes only a couple months for most smart employees to catch on, and move to another job.

My first couple tech jobs were at startups where I was paid below market rate. The first one had some serious shenanigans going on when it went down in flames; the second had no shenanigans, it just wasn't going anywhere. But I left, and my compensation very quickly caught up with and then surpassed what I thought possible. I probably ended up significantly better off, financially, by taking the hard knocks early and learning the lessons myself rather than paying an agent 10% to handle everything for me.

As they say, "when someone with no experience does business with someone with lots of experience, the person with no experience gains some experience."
For scooters or toys, would like to see quantities sold. Because I would expect that economy of scale would push prices down for the non-female-gendered versions.

Also I would wager it's more common for a girl to want a red scooter than for a boy to want a pink scooter, hence a larger market size for the non-female-gendered scooter. Not sure what to make of that, though.

> I'm not aware of any scientist that 'opposes LENR'

Say what? From the article:

Ever since 1989, in fact, the whole subject has been largely off-limits in mainstream scientific circles. Authors who do put their head above the parapet are ignored or rebuked. Most recently, Lundin and Lidgren reported that they had submitted their paper to the journal Plasma Physics and Controlled Fusion, but that the editors declined to have it reviewed; and that even the non-reviewed preprint archive, arxiv.org, refused to accept it.

This is not just about Rossi by any means; he showed up relatively recently. This goes all the way back to Pons and Fleischmann. I wish I could remember the name of the physicist whose career was destroyed for no more than being publicly seen to entertain the possibility that cold fusion could be real.

Read up on this a little bit -- you'll see that pretty much the entire physics establishment opposes LENR.

> being oversold makes a field toxic

Yes, and there certainly has been some overselling. Even if P&F's work had been replicated, one could legitimately criticize their handling of the situation (it appears that the University of Utah, their employer, had a hand in this). But can one seriously suggest that because some researchers made premature announcements and oversold what they had actually accomplished, we should punish them by denying humanity what would be an almost miraculous invention, if it could be made to work? That makes just no sense at all, but that's pretty much how the physics establishment reacted.

For stuff I need to be remotely accessible, I use BitBucket and a commercial GitHub Private account. For stuff that can be local only, a series of local git repos.

If security is a concern, I trust a provider like GitHub or BitBucket to secure my data better than I trust myself to secure it, esp. if I also want to be able to access that data remotely.

Then there's the ability to easily convert projects between public and private. Publicize that private side project when it's ready, or privatize the open project that you want to take commercial.

There are a ton of integrations built in to GitHub (not just GitHub Pages) that to me make it a clear win for now with BitBucket a strong 2nd in my mind.

The article seems to focus too much on the consumer side of the bandwidth equation. I think the real win for Netflix is the aggregate egress bandwidth savings from their DCs. If Netflix can halve their bandwidth (as the article seems to claim) without any appreciable loss in quality, they've just saved substantially in the infrastructure and peering contracts needed to deliver their content. I have no idea how much money Netflix currently spends on bandwidth/CDN, but I'd guess it's certainly in the 100s of millions. I can imagine that Amazon and Apple would be very interested in emulating those savings.
Price discrimination? Give me a break.

The demand/supply curve is different. Maybe parents are willing to spend more on their daughters? Maybe women spend more on consumer goods in general? Who knows, it could be a thousand different things.

Whatever the reason, I doubt there's a conspiracy to charge more for goods because of gender. How does that even work? If the retailer ignores the supply/demand curve they're losing money ... they won't do that. If they're charging at the intersection and prices differ between gender-specific goods due to any of the reasons I mentioned above ... well that's the free market? What's the alternative? If you start messing with the price you'll create either shortages or over-supply of the goods.
