The startup equivalent would be "it's easy to build the app, it's hard to get users". Not all apps can yield users, but lowering the bar to launch will certainly yield more opportunities for successful apps.
Very interesting, could you use this to build a good analog amplifier?

Is there any way from genetic algorithms to learn from good human designs as starting points and breed the together?

What about genetic algorithms for battery and solar cell design?
I listen to Chris Hardwick's Nerdist podcast. One of the things he points out about his career in show business, is that he didn't become truly happy with it and accomplish his goals until he started doing what he had a passion about.
The gist is that Webpack is diverging from Node, has difficulty consuming node/browserify modules, and encourages non-compatible syntax through its require() overloads (which are encouraged all over the docs).

Browserify also decouples its transforms from its core. The difference is that browserify can correctly identify which transforms your various dependencies are using, since they are listed in the package.json of each module, and it can resolve them automatically during the bundle step. This is not yet in Webpack, which makes code re-use more tedious.
Thanks! These look very promising (and neither featured on most of my searches). Any idea of something similar with a web frontend?
The issue is twofold:

- It shows Node compatibility is not a primary concern of Webpack.

- It is not a default feature of Webpack. Pretty much every Webpack project will need to include this loader config if you want to (safely) start consuming Node/browserify modules

I added the config to the article to detail the additional steps.

There are probably others much more familiar with cloud infrastructure who can chime in, but the AWS of science and the Heroku of science are two very different challenges, and I feel the analogies probably cross over pretty well.

Definitely having the infrastructure 'warehouse' layer that Transcriptic is building (with a real API! wow!) will be valuable. And like you hint at, power users won't need hand-holding, but 99% of the market of users will. That's where packaging, ease of use, and limited configuration seem to be the difference maker (Heroku starting exclusively with Rails).
One question to bear in mind when doing this sort of thing: just because it works in SPICE doesn't mean it's going to work as intended when you build it. SPICE is very ideal world. That may or may not invalidate this approach.

Imo even if it fails, it can come up with design and ideas you didn't think about. A lot of the time when you design something you just iterate over possible ways to do it. A computer can do this too.
You're a legend! This looks almost exactly like what I had in mind. It really bugs me that these didn't show up anywhere near the top in my searches (and I used quite a few terms). How do you know about these?
Most genetic algorithms break when you try to make them solve too complicated problems. They do not scale really well. Mother Nature has actually a lot of hacks to scale well. Evolution is a process that evolved by itself. If you want a genetic algorithm to solve complex problems, at one point you have to let the reproduction algorithm itself to evolve.

To give you an idea, only recently have we discovered that totally different species can exchange genetic sequences through virus (it is called horizontal gene transfer) and we are not really sure why sexual reproduction is a good idea when you can already mutate, have horizontal transfers and clone yourself.

"Make random mutations, select the best" is really not how nature works.
FRP according to this article is "Functional Reactive Programming", which Wikipedia defines as "a programming paradigm for reactive programming using the building blocks of functional programming"

I was disappointed to see the article was not about Fiber Reinforced Plastics.
There's almost no message you could put there that would stop humans from wanting to take a look. If there were warning signs on the pyramids, would we have stayed out?

"They kept their greatest treasures here and left these warnings so their enemies would stay out".

"How bad could it be? Surely we're advanced enough to open it! We have spears, nothing could harm us".

"This stuff is great. Put it on your arrows. Put it under the bed of your enemy".
I would say it depends. brfs is perfect since you don't change any node source to support the browser.

glslify is another useful one if you're authoring WebGL modules. Not only does it statically analyze the uniforms/attributes for use at runtime, but it also allows for modularization, minification, optimization, etc.

On the other hand, transforms like cssify and hbsfy might be better suited only for the application level.

In an ideal world; these transforms would be completely decoupled from the bundler so that Webpack, Browserify, or anything else can use them in the same way.
If you want to see the futility of external marking schemes consider the case of Gobekli Tepe (http://en.wikipedia.org/wiki/G%C3%B6bekli_Tepe) dating to 10th-8th millennium BCE. This place has inteersting structures and reliefs of mostly animals that are not currently understood. What's more:

"The site was deliberately backfilled sometime after 8000 BCE: the buildings were buried under debris, mostly flint gravel, stone tools, and animal bones that must have been imported from elsewhere."

The reason for filling it up, which probably took enormous resources at the time, is unknown. Why would they bury the site? Maybe something "bad" is buried there. But we know that anything that can harm us now wouldn't be technologically possible 10k years ago. Still ...

And you know what: We're digging it up!
This is the exact problem. If we have to explain this, you have missed it. Sorry, but trying to explain or try to derive a "sound" out of it is missing the point.
I've been tinkering about with writing my own shell at home, as an excerise in learning more about unix etc but bumped up against the limitation in that proper job control is currently impossible to do from within go (off the top of my head it was something to do with the inability to set the process group correctly for forkexeced processes). How did the author get around this, or does Elvish not have the ability to put processes into and out of the background?
The dictionary definition of the term "racist" refers to a systemic discrimination based on race. The problem is that the colloquial use of the term simply means that one is prejudiced against races that aren't their own. To clarify the issue one is trying to discuss, it's better to use the term "institutional racism" in order to clarify the point you're trying to make.
You can use it to build anything given enough time, and a proper full detailed and correct list. This includes things like: reaction when the input voltage goes dead, preventing poping, output resistance, harmonic distortion, ... If you would use this I recommend you try to use it on a small subsystem of the circuits, not the entire circuit, unless you are looking for something neat.
I however don't know how practical this all is :)
> * Most 'traditional cities' couldn't be built for anywhere near the same cost as a modern development.

Why is this? E.g. The author points out that narrow streets should be cheaper to build and maintain.

I grew up in suburbia, lived in a typical American city, and now live in a traditional city abroad. My best guesses as to why building a traditional city is more expensive are 1) construction might be more expensive because of the constrained space; 2) lots of roads are cobble stone rather than pavement; 3) maybe infrastructure (e.g. fire hydrants etc)

Are there other more important reasons? I really can't figure it out.
Those narrow streets are illegal because it's a problem for the fire department.

I have lots of old cities here in my region that stayed small (<10k inhabitants) and only few of the streets are narrow

Another problem is that you're pretty limited in city size if you can only walk: people don't want to commute for more than 1 hour daily
Its not until your late 20's and really 30's that you start to find out about and see people you've known in the past that were intelligent, productive people who's lives have been completely destroyed due to their drug addictions.

Maybe in your case. I was seeing people badly damaged by drugs (alcohol and heroin, mostly). I also know the only reason some kicked the heroin addiction was because they were allowed to ask for help without fearing imprisonment, since drug usage is not a crime in my country.
>> if you don't like noise you shouldn't live in the city

I couldn't agree more. It's unfortunate that it's quite hard for people working in some sectors to avoid cities -- and I feel that the New Urbanites and their opposition for out-of-town developments deserve some blame here.
Why don't we eject it into space?
Rand Paul introduces bill to reform civil asset forfeiture
This is equivalent to the following bash incantation?:

|while read b;do echo $((b*2));done
1
2
3

eof

(Better expressed with seq):

seq 5 \
| while read a;do if [[ $a -gt 2 ]];then echo $a;fi; done \
| while read b;do echo $((b*2));done

But we can do (a little) better:

# Ok, this is a bit odd, the filter is actually inverse...
filter()
{
while read it
do
#NOT SAFE!!
if eval ${*}
then
echo "${it}"
fi
done
}

map()
{
while read it
do
#NOT SAFE!!
eval ${*}
echo "${it}"
done
}

#Valid bash:
seq 5 \
| filter test '$it' -gt 2 \
| map 'it=$((it*2))'

>Common opinion dictates that we need the state to take care of public health; thus, in common opinion, public health is an issue of crime and punishment.

What's with the libertarians fondness for hyperbole? In common opinion, public health if firstly seen as a service the society provides in developed countries, especially if viewed in contrast with countries that do not have a functioning government. Secondly it is seen as based on rules. Yes, if you break every rule this amounts to crime down the road, but common belief in post-adolescents is that your precious personality is not constantly raped if you follow rules.

>Update: Most glaring example is Obamacare.

To most Europeans, Obamacare is simply the US catching up with other industrialized countries. I doubt anyone here except for a sub-percent minority sees this as the state stealing from its citizens by forcing them at gunpoint to pay up.
It's actually sitting in a variety of temporary facilities right now that aren't as safe...

My favorite kind of result. Much like how "tree huggers" celebrate blocking a nuclear reactor or bird-killing wind farm, and as a result the old sooty coal plant keeps running instead. Some victory. Some progress.

Sidenote, I'm sometimes a little befuddled that we would be afraid of putting radioactive material in the ground. The ground is already full of the stuff, and we don't spend much time worrying about an earthquake spitting up a boulder of yellow cake in our backyards. Ok, the concentration is different, but sometimes it seems like worrying about putting salt in the oceans.
Mining Our Reality (2009) [pdf]
I think the OP was implying that valets could photograph the house keys, then later go and rob the home of the car owner.

A locked door to a home is rarely a deterrent for a determined thief.

I mean, heck, the valet could just as easily steal the garagedoor codes from a garage door opener, right?
yes, that is right... you can Buy and sell on facebook.
They don't know who a key belongs to, they trust that you are the owner of said key when you upload it.
Should you use JavaScript or CSS
My best suggestion is to go back home. I'm sure you still have friends, and family that have some smidgeon of care for you. Rather than going it alone, as others have said, you need a support structure.

I know it can be tough, but suck it up (in terms of the family situation). And while you're there, take some of the remote gigs that I see the HNers here offering to give you. Until you can stand on your own two feet, and then you have to leave and remove yourself from abusive relationships (which it sounds like from what you wrote). But until you can do that safely, you're just shooting yourself in the foot.

Leaving mid-term was the big mistake here. I didn't understand how outside scholarships would be cancelled. There was a balance on my student account for the longest time that is now in collections. But other debts are simply medical related. It was a daily 100 mile round trip during therapy, and I let things get off track while I was getting treatment. At the time, it was the only thing I felt I could do.
Very disappointed after tracking down[1] and doing:

If things are that bad and you don't want to go back to school your immediate concern should be a job. Forget about an IT job - you aren't in a position to choose the job you want. Apply to everything and anything that has an open position. At least that will help you get back on your feet.
Interesting. Do you have any good links for learning more about the evolution of evolution? Thanks!
>* Modern business don't work in low desnity environments like this. You simply need to be as accessible as you can to as wide a market (of workers and other businesses you work with) as possible. Maybe once we are all working on the internet it will shift this way - but it hasn't gone far yet.

My impression was that traditional cities are higher density than modern cities. They're less dense than hypertrophic cities like Manhattan, but almost everywhere is.

Paris is 9 times denser than Atlanta, for example, according to Wikipedia. Can you cite any statistics showing traditional cities aren't dense? You might be right, but any place I've looked at that's traditional is also rather dense compared to the median city.

In addition to hiring people passionate about coding, I have found out that anyone who is really passionate about something (music/surfing/rock climbing etc) is a good programmer. Some of the best programmers I worked with were either crazy about programming or passionately followed through with something else in their lives. The key being that they followed through with their passion. Has anyone else seen this? Or is my data too limited to my personal experience
> The flip side of eating out in random places constantly is that I've had salmonella about once every two to three resident years on average.

You're doing pretty good. Almost every person who spends more than a couple weeks in China gets to be best friends with 拉肚子 [1]. And unlike lots of places where it happens when you first arrive and then you're over it, nobody ever seems to quite get acclimated enough to stop getting it every few weeks.

An old traveler's rule of thumb when in strange lands, don't eat the fresh raw vegetables and you'll cut your dealings with salmonella and other food borne diseases by some incredible percentage. Cooked, fermented or pickled will give you less trouble.

All that being said, the freshest food I've ever eaten came from Chinese kitchens. Chinese Wet Markets [2] are amazingly different than the Western equivalents (which try to maintain freshness via ice rather than keeping the food alive in tanks) and effective at providing unbelievably fresh meat, particularly seafood.

Optimization coaching for Spidermonkey
Thats a neat question. Will keep it in mind for the next interview in addition to the OP
In this video, one of Mozilla's most recent batch of interns talks about his experiences teaching the Spidermonkey JavaScript engine to list directly actionable optimization suggestions for arbitrary user code.

It's been a while since I did anything performance-sensitive in JavaScript, but if I ever do such a thing I very much hope I'd have access to these kinds of suggestions written and maintained by the compiler writers, rather than hearsay and ritual.

> the genetically-modified glowcats mentioned in the article is the closest thing I can imagine that could work

Except that the proponents seem to have forgotten the small fact of evolution. Species evolve. All the time.

Over the course of a 100 century timescale I would expect the glowcats to evolve into quite different species, possibly several such species, or perhaps going extinct. It's anybody's guess, really, and whether they would retain the colour-change genetics is at best nothing more than a rather long-shot hope. Or those genes might evolve to cause the organism respond to other stimuli than radiation.

The only certainty, here, is that such creatures will evolve into something different from what they start out as, so, almost certainly, defeating the original objective.
The real problem with this style of interview question is that it is good for those who talk well, and bad for those who don't talk well. I have seen my fair share of candidates who are great talkers, but can't code for crap. The interviewers who didn't ask coding questions loved them, but those of us who made them code knew they sucked.

You should have stuck with programming on the white board. That's the right way to find good programmers.
The public perception of the dangers of anything radioactive is quite exaggerated, the politicians in these cases are only representing the views of their constituents. Having said that, I don't think you can reduce the argument to something as simple as salt in an ocean. Like you (almost) said, the concentrations are extremely different, particularly if something goes wrong with the containers in the millennia they are buried for.

Not entirely related, but an interesting read: http://en.wikipedia.org/wiki/Goi%C3%A2nia_accident
It's a good point, some thoughts:

- The Chinese government is well aware of the pending demand/supply gap in electrical production. In response the government is looking at quadrupling it's nuclear power capacity by 2020...despite having some of the largest coal reserves in the world. China has 21 nuclear power reactors at present and 28 under construction. By 2020, Chinese nuclear power generation should reach 58GWe of capacity. Long term goals are to achieve 200GWe by 2030, 400Gwe by 2050 and 1.4TW by 2100.

- China is spending unbelievable sums of money on nuclear power research, including some of the most advanced Thorium fuel cycle research available. China is set to soon become only the sixth country to build their reactor designs on the international market (CPR-1000).

- Depending on growing attitudes towards modernity, the Chinese habit is for fresh, seasonal food, similar to France. This gets rid of lots of the refrigeration requirements. Though attitudes toward modernization could shift demand towards out-of-season frozen and refrigerated foods.

- This is already happening in Korea. Koreans have a different habit, a focus on long-term preservation of vegetables via pickling and fermentation (not quite as common in China), making out-of-season foods a more normal thing. More recently, Western-style, heat and serve and frozen meals have started showing up (after decades of basically instant noodles being the only instant food you could make). And Koreans not only have massive American style refrigerators (something not as common in France or China), but also have secondary "Kimchee" refrigerators to control the fermenting process on out of season food items. More traditional foods are being reformulated to tolerate long-term freezing, so you can prepare a heat-and-serve version of a complex home-made-meal in about 10-20 minutes. There's still not an equivalent to the Marie Calendar's self-steaming meal in 4 minutes, and microwaves are not as common in Korean households, but convenience and a greater number of women entering the workforce will probably change things. Will this influence China? Maybe. The cuisine is quite different, but cultural links might move things in this direction. And yes, energy shortages in South Korea are a problem, with various government suggestions about when and how long to use the Air Conditioner and even shutting it off mid-summer in some government facilities. Korea is also in a major nuke plant construction boom.
Actually, AFAIK, Al Capone went to prison for tax evasion; Wesley Snipes is a good example of imprisonment for tax fraud. Those are related, but not strictly the same (for example, Wikipedia says that in Switzerland tax evasion is a misdemeanor, but tax fraud is an actual crime). I have no trouble believing that plenty of people go to prison for tax fraud.

It may seem like there's a thin line between them, but IMHO tax fraud requires a lot more effort and ill intent than tax evasion (it may even be possible to not even know all the taxes you have to pay, like use tax in some US states).
