> the ability to spin up processes so lightweight that they make even Java threads look heavy in comparison - is the key to its success when it comes to parallel and distributed computing.

Except you can do the same in Java -- see Quasar or Erjang -- the JVM is so powerful that true lightweight threads -- just like Erlangs -- can be added as a library.

> I've found Erlang applications with BEAM to perform far better in that domain.

I've found the exact opposite. Java with Quasar fibers handily beat Erlang code. The more actual work being done, the bigger the difference (BEAM is excellent at scheduling, but pretty terrible at running user code; it's notoriously slow, which is why all important Erlang library functions are implemented in C, and why heavyweight Erlang shops do a lot of C coding; when you do Erlang, it's often Erlang and C if performance is important).

> whereas the JVM, .NET CLR, etc. were originally designed for imperative languages

So was your machine, yet BEAM runs on it just fine. You can like the imperative style or not, but it's more general than the functional one when it comes to implementations on real hardware. BEAM runs on an imperative, shared-state machine, and creates a nice abstraction. You can do the same on the JVM without loss of generality, and, as it turns out, with a nice boost to performance (because HotSpot's JIT and GCs are state-of-the-art). The only advantage BEAM has over the JVM (or at least HotSpot) is a better level of isolation between processes (i.e. it's a bit harder for one process to impact the performance of another, because they have sort-of separate heaps). But again, BEAM is a fine, beautiful runtime that is perfectly suitable if you need good concurrency but aren't worried about processing speed.

> Maybe because the equivalent Haskell codebase to a "big" project in most non-declarative languages ends up being "small" in comparison? Or are you talking about importance?

Well, both. Haskell has never been used to write a large ERP, airport management system, manufacturing automation, an air-traffic control system, device drivers, an OS, a database, a banking system or a large social network -- take your pick. It may have been used to a small extent for some specific projects in banking, but that's about it. The only large, complex, "interesting" from a cost estimation perspective ever written in Erlang is its own compiler (and possibly other compilers). Now, I may have missed one or two specific projects, but their rarity only demonstrates the problem. Go, a much younger languages, is already more battle-tested than Haskell and even Go is far from being truly battle tested, so this says a lot.

That's because intervals tend to just keep growing. Without some function to make the interval smaller or otherwise keep it bounded, cumulative interval arithmetic tends to be useless.

Using the rounding mode to calculate once with rounding down, once with standard rounding, and once to rounding up will give a much better indication of whether or not an algorithm is sensitive to roundoff error.
Kinda lame and not in line with what made PageRank so successful. Google should "not be evil" and have the decency to be as neutral as possible, allowing legitimate clicks and backlinks to judge the relevance of a website. If people can't stand websites that aren't tailored to mobile devices, they will simply leave and find another. I personally don't mind viewing a 20-year-old website through a little mobile browser if the content is satisfactory.

If they are to change anything in this area, they should simply put a little distinguishing checkmark by a mobile-friendly search result, but leave the rankings unchanged. And this should obviously be the case only when a user is on a mobile device.
Where is your evidence of that?
Another commenter suggested PubPeer.

I think this might take off in physics if the ArXiv interfaced with, or copied, PubPeer. Doesn't address most of my concerns, though.
The average keeps getting higher and the top-tier improves because of non-incremental creative leaps, achieved by statistical outliers in the new-blood people who create "more content". Large sample sizes are needed to yield the good stuff.
yes ! refactoring.

I am not going to talk about my solution since its way too radical for HN. I do not think a libertarian approach will work.

What you want is to prevent having any single subset of the human population from having too much power. Any single government ( cough US, China, India ) or company.

We want the capacity to dynamically react to events much quicker.

Look at the largest companies on the planet, Its almost impossible for them to react to changes in technology etc.

And companies are not even that big compared to countries.

How long do you think its going to take the US,Indian,Chinese govt to implement a voting system that takes the same effort an facebook like ?

I know it sounds crazy, but its technically possible to do it.

If you break up all these large countries into small countries it wont be possible for things like wall-street to exist in the first place. Local voters can see their elected representative rather than have someone 1000s of miles away making decisions for them.

I derive these types of thinking from my experience in software and algorithm. when was the last time you saw a algorithm that does everything ? the best ones are small.

It also doesn't take away the capacity for humans to embark on large projects. If you can get concussion you can do all sorts of cool projects.

Anyway My thinking is really radical and its going to be 100s of years before we are there.
Most of those do exist on exchanges. The mechanics usually involve a fee attached with your fill ratio (ie the number of orders/number that actually trade).

The thing about spoofing is that it doesn't require tons of cancels. Done right it falls well within the bounds of normal trading ratios.
MPFR is sensitive in exactly the same way. Just because you can arbitrarily increase the precision of results with that library doesn't mean that it isn't still sensitive to roundoff error.
is there a price page somewhere?
Yeah, right now it seems tablets are the "best" option, but I actually think, for technical materials, where you're jumping around, marking pages, etc, more frequently, physical paper is still superior.

Well, save for the fact that technical books are rarely coil bound. At least a digital book stays open when I set it down on my damn desk!

yep. It is a stage in civilization development and we need to move past it onto the next stage - inter-species communication and coexistence which will ultimately allow our brain to get to the state suitable for communicating with higher [than human] species too. Right now we're just keeping ourselves locked in the anthropocentric "top-of-the-food-pyramid" closet, and sticking to such narrow limited worldview significantly slows our civilization development.

I wonder if MLBAM would get more publicity (especially in this community) if it wasn't tied to Major League Baseball. According to the article they had 60 million stream on opening day which seems to be a multiple of Twitch's record for a single day. But since MLBAM is a private company that has no intention of ever being acquired or getting an IPO, it is mostly ignored in this space even though it might have a bigger industry impact that many companies we focus on.

These articles always crack me up. This sounds great on paper, but the city is still messed up (and probably irreparable in my lifetime).

The article is talking about Downtown Detroit (as in 3-4 square miles). Detroit itself is a MUCH larger city... 130+ square miles. Not to mention... you only have 600k residents living in those 130 square miles. Focusing on 1% of the area (for the white and rich) is not going to help the rest catch up.
> The difficulty I see with the current and future legal landscape is that there's no clear distinction between right-to-modify and right-to-distribute.

In the context of entering a contract, I don't see either as "rights." If you sign a contract saying that you will pay a certain amount to use a tractor without modifying its internals or distributing copies of its source code, I am fine with a legal system enforcing that contract.
"To my mind the admissibility of evidence found during a search should have been limited to the original purpose; while it would not be entirely unreasonable to confiscate contraband found during a search, but it's not reasonable to prosecute the guy on that basis.

Sorry, but if a person who owned the place consented, the end result is always admissible.
Period.
If they didn't consent, it would be different.

I can't see why you think this reasoning would ever apply here.
There are some important differences between the case that you cite and this case.

Specifically, in this case the officer said that he had no reasonable suspicion that another crime occurred, and the dog sniffing was not part of the exception for "officer safety".

In the case you cited, the officers had an objective "reasonable suspicion" that a crime occurred (though obviously the accused in the case suggested it was not objectively reasonable, the court disagreed). Then during an investigation of the house, both for evidence of the crime in question, and to check the area for officer safety, the marijuana was found.

If evidence of a crime if found while investigating a different crime (where the reasonable suspicion is met) or where it falls under the exception for "officer safety", then it's fair game.

This decision doesn't change that standard, or even touch it since reasonable suspicion, and officer safety were not relevant to this case, and were relevant to the cited case.

So on the surface, they may appear similar, but hit different points of the law. On the flip side, had evidence of the meth been visible in this case, or the officer had any other reasonable suspicion of a crime, then this case would have likely been decided differently.
100 times this.
I want to state for the whole world (even though this thread is a bit dead) that Paul Irish is a really nice dude and the barriers to entry to help are tiny in jquery.

I remember one day just showing up in #jquery on freenode and complaining about some spam on their wiki. 10 minutes of talking later it was "Well, do you want the keys to the kingdom to maintain it?"

I think a big reason jquery was adopted so heavily was not just the tool being useful, but the attitude and the community around it.
Understood, but we're still taken advantage of massively by so-called Australian Rupert Murdoch.

Example: Formula 1 bait-and-switch. It was on free-to-air HD (one of the few HD programs actually shown in Australia).

In February (one month before start of new season), Channel 10 (partly owned by Fox) switched the rights to Foxtel (pay TV). To watch it in HD on Foxtel will cost about $80/mo.

Free To Air in Australia is dying a slow death, but there's no reasonable alternatives. Major sport here is shown in SD, except randomly if they maybe decide to upscale it, or show it in 1440x1080i (very rare though)
Thanks for the StaffJoy shout-out, Jeremy!

We're finishing up our first week of deployment with a real workforce and finding that automated shift scheduling that better fits supply to labor demand can save about 10% on labor costs, which is a huge amount. Modern workforces get better margins through efficiency and automation, and that creates the opportunity for a new generation of mathematically-driven workforce management tools like OnFleet, Instacart, and AnalyticsMD.

We're entering alpha testing with customers in the bay in the next two weeks - if you're interested in trying our product, shoot me an email - philip at staffjoy.com.
> Books are hard to copy

Err, no, it only takes half an hour at most and a Xerox machine. It's much cheaper than buying it too. We used to do it all the time when I was in college, which helped a lot given that sometimes we needed books that were out of print.

And btw, the best thing about a printed book is that it's forever yours and you can rent it, burn it or copy it with no technical restrictions ;-)

> Writers have to get paid, and people are cheap and don't want to pay them

Welcome to the world of capitalism; supply and demand is a bitch, isn't it?

My problem with such an argument is that it tries to take a moral stand, whereas there's no morality in it, because being paid for shit is not a fundamental right. Plus in a world in which copyright terms keep getting extended such that Disney will never lose their rights for Mickey Mouse, some people find it hard to give a shit about copyrights.

But the freaking elephant in the room is that DRM does not protect the interests of "creators" and it does not stop people from pirating content. DRM only achieves two things - (1) lock-in for the company owning the platform (e.g. Amazon) and (2) milking loyal customers.

As an example, I'm resetting my phone like once every two months or so and reinstalling everything ... the Kindle app is now telling me that my books were downloaded on too many devices and so I can't download them. I can't "unregister" devices either, because this is simply a software bug. I then searched those books on torrent sites, found them, downloaded them and I'll never buy books from Amazon again.
I think the easiest answer to that question is that there's rounding happening in almost every step where you do something with them. This also includes parsing from decimal floats in textual representation and outputting as decimal floats in textual representation.

The funny thing is that if you work with decimal floating points you usually don't get any of those effects because you often stay inside the accuracy/precision that the float can hold. Yet they're seen as useless.

PG addressed this earlier in the quote but I left it out because it was already pretty long.

"If you want to reduce economic inequality instead of just improving the overall standard of living, it's not enough just to raise up the poor. What if one of your newly minted engineers gets ambitious and goes on to become another Bill Gates? Economic inequality will be as bad as ever."

So what is the more important goal to raise the overall standard of living or reduce economic inequality?

Before you tell your friends that Jay-Z has only 98 problems now: Rodriguez v. US doesn't say a dog sniff can't be part of a traffic stop.

Alito mentioned in a separate dissent that - as a result of this ruling - he expects officers to change the sequence the activities involved in a traffic stop so that the license check and citation are not completed until a dog sniff is done. This ruling may be a bit of a moot point, except in cases where officers don't follow the proscribed sequence of events.

I would have to be paid $1K per year to switch to a yahoo email account, and I'm not even sure I'd be happy with the offer.
How is that fair though. You make a statistical restitution of sorts but if there are 20 jobs and 100 candidates of equal standing. 50 candidates fit one biological classification (A) unrelated to the job and the other 50 fit another (B). How is it fair then to ensure that a certain number of A > B get the jobs available?

Why is it that when the number [getting the jobs] A < B by design it is wrong, but when A > B it's right.

Moreover what you appear to be arguing is not even that the candidates have equal standing with regard to ability to perform the roles but that you should select A > B even if on average candidates in group B are more able to fulfil the job requirements.

So now you reject candidates who are more able to do a job simply because they fit unrelated classification A. How is that discrimination good?

Why is it alright to antagonise people now because of their race when it wasn't in the past; don't you think that will just foment ill will and a greater focus on irrelevant biological classifiers?

We shouldn't discriminate against a poor person because they're poor and in group B, we should offer opportunities for all poor people to pull themselves up by their own bootstraps regardless of unrelated biological classifications. By this means we will remove needless discrimination rather than shift it around. If, in order to make restitution you feel that there are excessively many poor people from one group, then make more opportunities available to all poor people. That way all those who wish to take advantage can do so regardless of whether their earlobes are attached or whatever hangup you have.
Yes, people shouldn't be arrested for possession.

Indeed. Legal warantless surveillance is admissible in court, while the illegal kind is much less so. Not only will the use of surveillance grow, but so will the likely consequences of being surveilled.

Its about binary floating point arithmetic in computers, though one could do a similar thing for, e.g., decimal floating point. (Though decimal floating point rounding issues will show up much more rarely in many real-world classes of application.)
In reality though, isn't it not going to change because the people that care/are in a position to care leave? I get that parents want the best for their children and I don't fault them for that, but I don't see it changing if people are like "Yeah it's bad, so I left, I wish I could help from over here."

Once you become rich not only does it become significantly easier to spend money, but it becomes significantly easier to make money. Essentially your money just grows through investments, dividends and compounding interest. You gain more money by doing less work, so you stay rich for basically the rest of your life.

This is a common trend among rich people and among experts who actually study economics it is also the prevailing reason behind the wealth gap.

> 2) the richest Americans, as measured by Forbes 400, demonstrate that the majority are first generation in that class. This you can check yourself quite easily.

Rich people as individuals tend to stay rich. However wealth is diluted exponentially when passed from generation to generation as inheritance. Think about diluting $100 amongst nodes for each level of a binary tree. The root node gets 100, the next generation each node gets 50, the next gets 25, 12, 6, 3... two generations and already the wealth is divided by four, and this only accounts for people having two kids, rich people tend to have much more!

Sometimes police will threaten to summon the K9 if you don't consent to a search. [1]

If extending a stop for dog sniffs is now unconstitutional, does that mean any officer using this tactic was making an illegal threat, and thus any search thereafter must be thrown out as coercive?

At some point you have to cut your losses and tell those people to relocate or pay for services outside the footprint the city is able to serve. Or let those residents incorporate into a new city and break Detroit up into 6 or 7 new city municipalities and have the State reboot it.

It hasn't come to that yet since the bankruptcy case has closed, but without the state of Michigan serving as a financial backstop, I am generally skeptical that Detroit City Council can manage a pool of money without going bankrupt. By the way, keep an eye on the pension funding levels for city employees, that is the next shoe to drop.

Downtown has to thrive and be a destination so Detroit can be a place for companies to relocate so that it can compete with other cities throughout the country for talent.
An obvious representation is a convergent stream of fractions. This will also quickly drive home why you cannot implement equality.

The other obvious representation is that of first order formulae over the theory of real fields, but then you need to check equivalence of arbitrary formulae. You ultimately need a limit operation to be included and now you're sunk. You'll also probably wish you were implementing the complex numbers instead pretty quickly.
