I think you're just spouting a lot of buzzwords, and you're actually conflating (a) the relevance of chaos theory and (b) criticisms of normal distributions in economics.

A major recent criticism is of some economic models which have assumptions to the effect of "returns on this investment will be normally distributed." The criticism is that evidence seems to suggest that returns are not actually normally distributed; rather they have "fat tails," meaning that extreme events are more likely than with a normal distribution. And this error causes economic models to discount the role of these unlikely extreme events.

The Black-Scholes model effectively models stock prices as Brownian motion. This boils down to a single assumption: stock prices are the buildup of lots of very small INDEPENDENT random events (with FINITE variance) that occur over short times periods; this leads straight to Brownian motion. Brownian motion is indeed continuous; however, it is nowhere differentiable with probability 1. Because of the assumptions of finite variance and independence, the CLT tells us that returns will be normally distributed. So here, people pretty much agree that it's always these assumptions of independence that cause these models to predict poorly.

This is totally different from chaos theory. First of all, chaotic systems are not necessarily complex. Here's a chaotic map with a "nice little formula":

f : [0,1) -> [0,1)
f(x) = 2*x (mod 1)

While this is chaotic, we can understand much about this map. For example, each application produces an entropy of 1 bit (see entropy of dynamical systems...). So this is a map that "produces randomness" in a way. This is philosophically nice, because probability theory itself doesn't at all explain how randomness comes about.
the case the parent refers to is Marbury V. Madison, where SCOTUS assumes the ability to interpret matters of constitutionality.
I like the second part. It's spot on.

When we were designing our current project, we have spent whole days together, listening to di.fm, drawing on papers, scribbling on whiteboard, thinking, discussing. We managed to stuff completely coherent idea of the architecture into our heads (and into skeleton code) so that even now, after an unwanted 3 month break we can continue writing pieces and know exactly how do put them together.

From there on, it's mostly headphones and only infrequently some coordination discussions.

Why am I even writing this? It might be that I am just happy about it...
Exactly. Installing postgres on any Debian system is a one line "apt-get install".

The only part that might be considered complicated is if you want to open up the server to non-local network traffic as you have to edit both the pg_hba.conf and change the listen address in postgresql.conf.

It's like that so that it is secure by default. Anyone who thinks that's too complicated doesn't understand what that means or why it's important.
Congress itself was the one who has authorized the current 'War on Terror'.

They didn't declare that the nation itself is in a state of war, which is itself accurate if you look around in the U.S., where the war (and wars) have had minimal effect at home.
The fascinating thing is that this article, which compared to US press, sounds like a liberal paranoid rant, is being published in the Frankfurter Allgemeine Zeitung, which is about as liberal as The Wall Street Journal ....

This thing is a PR disaster of the greatest magnitude.
> In this and candy box you're not really supposed to pay attention to the window for the first couple minutes. There is literally nothing to do.

Yeah, interesting call, that. When I played Candybox, I was told "before you dismiss So what it, wait until you get 60 candies, then shit gets real".

So, what does a self-respecting hacker do, when faced with 60 seconds of "literally nothing to do" ... except the challenge of opening the JS Console to see if I can make that counter run faster, preferably in less than 60 seconds? ;-)

(answer: yes, it was in fact fairly easy)

Why doesn't the standard library warn when it knows %Lf might be too long?
I think the hard part mentally (that your incredibly great explanation completely alleviated) is trying to guess at the meaning of the interplay of all the instructions, addressing modes, register overlaps, and calling conventions. It seems like the only way to turn that from difficult (impossible) guess-work to mere sand-unloading drudgery is to either have a lot of it memorized already, or to have a very strong command over the various documentation resources.

Okay, so what about all of us that don't believe in the supernatural? Do our rights come from an all-loving God, or are they creations of man like everything else in society?

US allies do spy on American corporations and the US Government. Israel for example has been caught over and over again spying on the US, and is a big concern for US intelligence agencies.

http://bigstory.ap.org/article/us-sees-israel-tight-mideast-...

Countries we're neutral with (not allies per se, not at war with), such as China, routinely spy on the US Government and its corporations; ditto Russia (and that goes back a long ways). And of course China is America's largest trading partner, so we're quite friendly there.

Or for example, the UK spying on the Germans:

http://rt.com/news/uk-germany-wiretapping-criticism-201/

I would argue that all the major countries are attempting to spy on all the other major countries.

Perhaps none so successfully or belligerently as the US of course.
Mine too. Took ~5 hours to finish.
Being in receipt of tax revenue is no measure of being a useful department. And how does it work when other countries are found spying on the US or UK? presumably this is also perfectly acceptable.
Thanks. Never had a knowledge about thermodynamics. I just googled perpetual motion and the laws of thermodynamics. And yes, I agree that my comment above doesn't follow those laws. It's good to learn these new things. :-)
First of all the problem, as it often is, comes from centralization on the internet.

Which is a matter of government policy. When the internet was invented, hackers and cypherpunks said it should be decentralized. Lobbyists and Congressmen said it would be subsidized as something along the lines of television: few senders, many receivers. And then ISPs even said: we'll take public subsidies for infrastructure and not even build the infrastructure.

The result is that America and Canada in specific have crappy net access, and the world at large has a centralized internet rather than a decentralized one. Why? Because nobody ever required that we commoners receive publicly-visible IP addresses and symmetric bandwidth with which to run our own servers.
Several such lists have been submitted over the years, worth checking them all:

If your extremities' temperature is cooler than the ambient temperature, how did you do that? Heat pumps in your arms? ;)

It would be trivial to put some circuitry in there to rectify the voltage so it works in either direction. No separate version required.

(changing ambient temperature is the obvious answer to my joke, btw)
This is really dumb.

Firstly, I'd bet dollars to donuts that his ISP advertises "up to" a certain speed and includes language in the T&Cs that specifies speeds may vary based on a variety of factors.

Secondly, is this even taking network overheads into account?

Thirdly, saying "kids in Africa might have 14kB/s for their whole connection, therefore that amount of bandwidth is worth fighting for" is dumb because it assumes constant marginal utility of bandwidth when that's obviously not the case. Going from 0kB/s to 14kB/s is a hell of a lot more valuable than going from 14kB/s to 28kB/s, and going from 14kB/s to 28kB/s is many orders of magnitude more valuable than going from 882kB/s to 896kB/s.
Good catch, I had no idea. Glad to see this!
>When push comes to shove, they're all Keynesians...

But that has nothing to do with economics. That's because they want to spend money, same as the Democrats. There's precious little reason to believe anything good has come from monetary policy in recent years.
But even that isn't enough, you know.... There's
talk nowadays in publishing circles about a new device for
books, called a ReadMan. Like a Walkman only you carry it
in your hands like this.... Has a very nice little
graphics screen, theoretically, a high-definition thing,
very legible.... And you play your books on it.... You
buy the book as a floppy and you stick it in...

...

And just think when the ReadMan goes
obsolete, all the product that was written for it will be
blessedly gone forever!!! Erased from the memory of
mankind!

...

Now I'm the farthest thing from a Luddite ladies and
gentlemen, but when I contemplate this particular
technical marvel my author's blood runs cold... For God's sake don't put my books into the Thomas Edison kinetoscope. Don't put me into the stereograph, don't write me on the wax cylinder, don't tie my words and my thoughts to the fate of a piece of hardware, because hardware is even more mortal than I
am, and I'm a hell of a lot more mortal than I care to be.

I think you've misunderstood the point I was making, which makes sense in context of the video in the OP. I'm not arguing NPM > Maven. I'm arguing NPM is conceptually simpler and easier for a newcomer to use than Maven.

Namely, the speaker made reference to "weaker" DB technologies being used due simply to a frictionless barrier to entry. Mongo was cited as one example. The use of MySQL over Postgres was another. This is basically taken verbatim from the presentation in the video.

This isn't about which systems are "better" or "worse", but which are simpler to get up and running with. Mongo is super duper simple to install and configure. So is NPM. Managing complexity is a real and valid concern, but also not what we're talking about here.
It would be nice to know if it's limited to iOS development or would also work for webdev, I can't that mentioned anywhere (though it might be obvious to those familiar with Codea.)

Seems quite heavily weighted towards Web development but a good list either way. Thanks for sharing.
True, but when it comes in handy it can be immensely so. I was looking at a customer crash dump at work the other day and the callstack shown by two different debuggers didn't make any sense, it was showing calls sequences the code clearly didn't make. Looking at the raw stack in memory and using the disassembly to help see the layout of the frames made it (relatively) easy to see there were a couple of calls in the sequence that both debuggers simply weren't showing. Once I had the real sequence and the dissassembly to see how the frames evolved and recompute call targets for earlier in the frames life it became a lot easier to see what was going wrong. If I hadn't been able to do that (and my ASM skills are definitely not strong) this would have been a No Repro (and hence no fix) bug for sure.
Yeah, he'd be justifiably pissed if he got 50% of the maximum advertised bandwidth, but 98% - Who's his ISP, and do they have service in my area?

I've seen it growing in popularity firsthand. The projects I'm involved with have seen large increases in contributors, mailing list activity, traffic on Github, downloads on PyPi over the last four or five years. PyAtl and some of the other local groups with Djangonauts in them have grown sharply over the last two years (in the Atlanta area). People from other backgrounds are more likely than ever to at least have an idea about what Django is (whereas when I was starting back in 2006 people would just stare at you).

I like playing with Go and the other newer/trendy stuff, but the thing I like about Django is that I can just sit down and get work done fast. It's not sexy, it's not clever, it's not magical, but I don't want it to be any of those things.

As a side effect of this, a huge percentage of the population is too busy getting stuff done with Django to blog and interact, aside from asking questions and getting advice. You know, like Instagram, Pinterest, NASA, National Geographic, Disqus, Mozilla, The Onion, PBS, and many more.
Here's the productized version of that idea: http://www.thepowerpot.com/

I thought it was a good presentation, the chart on frameworks around time 40:00 shows what I've been thinking, seeing. If I started a site today and I had full say, I wouldn't use Spring due to its complexity (although VMware people do make a fine product - for Enterprise stuff it makes sense); still it would probably be either Grails or Play. The problem I have with Play is that even their tutorial seems to me to try to brainwash you into getting into Scala, the templating system is based on Scala. That's where they lose me. Grails I've used to build a small test site and it was great. There, I made up my mind, I would use Grails.

Buried in the 2nd to last paragraph:

A big part of the ease of use of package managers comes from implicit trust in the maintainers of the repositories. Convention over configuration dictates you as a node dev trust the NPM repos. Ditto for ruby gems.

Like most things java related maven is very extensible from an env perspective. People complain about java programs/tools being over engineered but in this case it's a good thing.

One of the great things about maven is that you can trivially point it to a repo you control that is shared across a team or even an entire corporation. This allows whitelisting of packages, confirmed trusted versions, and consistency across different applications (my app and you app both use library X and we know its the same jar).

How many of you actually verify the origin of the modules and libraries you use as dependencies?
"I don't think larrys was suggesting otherwise, just that it'd be interesting to know "

Exactly.

My feeling is that under the "work expands to fill the time available for completion" Parkinson's law https://en.wikipedia.org/wiki/Parkinson%27s_law we would find that the size of that division didn't drop as much as it could (ratio wise) since a detective can always follow more leads. And if those leads led to arrests the labor would be justified. Without regard to whether the extra work was the reason or not.

All this of course assumes also that the staffing level was appropriate to begin with. No way to really know that. After solving crimes in NY Metro is not the same as solving crimes in a different geographic area (travel time or other support resources could be different).

For what it's worth, most of the cost of providing a net connection is in the delivery to your endpoint ("last mile") and customer service. If all you want is X Mb/s and you can accept it at a place convenient for the ISP, prices are well under $10 per Mb/s per month. That is, a 100Mb/s bidirectional handoff will cost you significantly less than $1000.

Now, a 7Mb/750Kb connection? The return bandwidth can't be shared, so that gives you an idea of the contention ratio: about 1:10. The ISP is overselling their bandwidth ten times. This is probably reasonable for a consumer ISP. On the other hand, their cost for that bandwidth will be substantially under $7/month. The rest of the cost is going towards actually getting it to you, running a few services, customer interaction, and keeping everything repaired. Those other costs are relatively fixed -- it doesn't matter how many megabits you're buying, it costs the same per person -- but over-differentiating the prices seems to make sense to the marketing departments.

No sorry, I don't trust you. You might be an engineer, but you don't seem to know how networks work.

Ask HN: Encyclopedia of discrete approximations, with reference implementations?
What does the community feel is the best reference out there for discrete approximations, preferably with reference implementations, the more comprehensive the better?

An ideal format would be the traditional name of the formula or number being approximated, a list of other common names for said formula/number, a list of "areas of applicability", a list of approximations annotated with computational efficiency, convergence info if applicable, reference implementations and hints for how best each approximation should be used, and finally a list of related formulas/numbers.

I recognize that a lot of this is on Wikipedia, but I'm looking for a dedicated resource that's a bit more cohesive.

Print resources are fine, but I'd love to find a good digital resource for this.
It doesn't have to be measured to 7 significant digits in a scientific way. But if you spent a week trying out various editors every now and then for the kind of work you do, you should at least be able to make a more informed choice about which editor to use. Or you may discover functionality in another and see if you can get it in your current favourite.

I've interviewed people who were exposed to Nano at school, and have never tried out any other editor. They are missing out on productivity improvements available in many other editors. More middling of the scale I've also interviewed someone who used Eclipse as their first editor and has proceeded to use it ever since despite not working on Java projects any more. That isn't bad per se, but I rank someone higher if they at least try out others every now and then.
