In my experience (have some family members running small businesses as well, including my father) the crunch seems to be coming from the fact that the middle class has just enough money to make mortgage / car payments - which keep them in the middle class - but not enough left over to spend at small businesses. If compensation was rising in accordance, there wouldn't be a problem. However large corporations are hoarding cash like crazy and leaving employees out in the cold which in turn harms small businesses.
I've thought about that when I was a little kid. True story!
That's really cool. An easy way to understand it is by thinking about bunching. Since you're only flipping until you hit the first matching sequence, on average you'll hit the more evenly distributed sequence more quickly than the bunched sequence.

Multiple heads in a row are more bunched than transition sequences because, for example, a sequence of three heads in a row will include two sequences with two heads in a row. You can't do that with a transition sequence--it takes at least four tosses to get two identical transition sequences.
I graduated in 1999, and that too in India. So imagine my situation :).
I finished the Coursera ML class recently (though I had done some ML prior to that) and I really enjoyed the class. You should definitely aim to finish it. The assignments towards the end feel relatively simpler compared to the initial ones.

The TL;DR is it's a step in the right direction. Their platform still has a lot of problems IMO, but at least it's improving.
"Bloodletting (or blood-letting) is the withdrawal of blood from a patient to cure or prevent illness and disease. Bloodletting was based on an ancient system of medicine in which blood and other bodily fluids were regarded as "humors" that had to remain in proper balance to maintain health." - Wikipedia

I am pretty sure leeches are still used, they are highly effective for the reasons you describe, but bloodletting is a dangerous practice of trying to get rid of blood from the body to cure someone.
I signed up, but Open Tasks is empty right now. It might be interesting to report info about completed tasks---to give an idea of the prices and type of PRs being requested.

This is an interesting idea with several possibility of incentives: project owner, project users, or companies employers could sponsor these PRs.

Also could be useful for learning/tutoring---formulate a question you're stuck on as an Issue and let an expert show you the way with an educational PR.
Hi HN! A couple of us from the Magic Pocket software team are around to answer questions if anyone has some.
> 1) What are current 2016 network speeds between cloud providers?

I'm pretty sure if you need to ingest ~150 TB you can pull it from AWS/S3 much faster than you think. To absorb ~150TB you'd need ~75 nodes. Given you can download partials of Common Crawl, you can break it up to 75 nodes downloading in parallel with 1gbit/s ports you should be able to pull it down relatively quickly compared to your estimation.

I'd bet you could pull ~150 megabytes/s [16 mbit/s per node].

http://commoncrawl.org/the-data/get-started/

> The Common Crawl dataset lives on Amazon S3 as part of the Amazon Public Datasets program.
From Public Data Sets, you can download the files entirely free using HTTP or S3.

https://www.hetzner.de/en/hosting/produkte_rootserver/ex41s

> 2) What's the cost of ~150TB of network bandwidth?

Free.

> There are no charges for overage. We will permanently restrict the connection speed if more than 30 TB/month are used (the basis for calculation is for outgoing traffic only. Incoming and internal traffic is not calculated). Optionally, the limit can be permanently cancelled by committing to pay € 1.39 per additional TB used. Please see here for information on how to proceed.

> 3) From those datapoints, can we derive a rough rule-of-thumb where a certain amount of data exceeds the current capabilities (speed or economics) of the internet backbone available to projects like Common Search?

I suspect you are greatly overestimating the difficulties since most DCs basically let you ingest/download for free because of the asymmetry on their networks.
Can anyone tell me why 9:31 and not 9:30?
Super interesting, shame both my home and work are engulfed in moderate pollution :/

Ask HN: Data Science – What is it? Should I get into it?
I'm thinking about where to expand my skill set and I'm wondering if Data Science is a good skill to acquire. Is it something that will grow in the next 10 years? It seems like it's only growing, but I'm not exactly even sure what it is. Thanks!
So I'm assuming this is only for artists right now? Is the product ready to be used or are you just looking for money?

The ABC of 3D scanning
What's interesting, is that if you reword this slightly, and ask, "If you flip coins until you get either a head followed by a tail, or a head followed by a head, how many flips on average are required before you get a Head, followed by a Tail, versus a Head, followed by a Head" - the answers are 3 and 3 respectively.

But worded, "If you flip coins until you get a Head followed by a Tail, or flip coins until you get a Head followed by a Head, the answer reverts back to 4 and 6."

Very counterintuitive.
I really like this. Kind of reminds me of https://github.com/clibs/clib.
Real question: In the US is it possible to get your driver's license cancelled and re-issued when it is stolen?

That may have helped here, since when the cop ran the license it would have turned up stolen. Assuming cops are entering license #IDs into the system rather than just recording the name.

As an aside I thought driving licenses were all picture IDs now? How did the cop not spot that the person handing them the ID wasn't the person ON the ID?
So much anger!

I left Jamendo 6 years ago so I have limited influence on what they do now, unfortunately.

Common Search is a nonprofit and 100% open source so it is fundamentally different.
From my experience, modding implies a lot of experimentation, you're often playing with unknown rules as there are very often big gaps in the documentation and you only have other mods (Which very often make their own errors) as examples. An api to an open source game must be much easier to understand.
Optionally via Carrier Pigeons or Owl Post for the few without internet access.
No offense taken - I didn't notice to be honest.
It varies by state. In Iowa, used to have your SSN as the license id, so it was not easy to change. Now its just a serial number, so it should be possible.

"I haven't used Erlang but I have done a fair bit of Elixir now."

I've programmed in Erlang for somewhere around 6 years. Which really makes things like "I'm not certain you understand what the OTP is giving you" rather silly. [1]

You're falling into the exact trap I was talking about, which is implicitly assuming there's some sort of magic sauce that only Erlang brings to you. You also are so busy disagreeing that you didn't notice that I already said pretty much everything you said. (What is it about Erlangers explaining back my own points to me, only angrily as if I didn't get the points I just made? I get this more from Erlang than any other community.) I'm not kidding about Erlang being a milestone language. But it's not magic.

"You are arguing against a straw man for me here."

What I'm arguing against is Joe Armstrong's attempt to redefine terms to suit his advocacy. If that's a "straw man", take it up with him, not me.

[1]: See also http://www.jerf.org/iri/post/2930 . And for goodness' sake, please do not reply with another laundry list of the points I already made in that post about how that isn't exactly what Erlang has back to me as if I didn't make them already. I've already been through that. (You know the differences because that post tells you exactly what they are.)
https://academia.stackexchange.com/questions/18625/do-spring... suggests otherwise. Where do you see closed journals charging 1-2k to submit papers?
Can they? Genuine question.
See this posting all the time have you been continuously hiring or unable to find a qualified applicant?

Are these strict requirements stifling grown and innovation in your Lab? Do you have the freedom to hire whomever you want, or is the research funding contingent (implicitly or explicitly) on meeting these hiring guidelines?

What if you could use some of the funding to hire for hackers with decent technical chops and a passion/background in science? I feel like there are others like me that could fill this role, but aren't post-docs/published research scientists. Love to learn more about how you're handling this process. Cheers.
Apple showed the Chinese its source code so they could verify that it had not been back doored (per Snowden's accusations). Since this did not entail revealing their signing keys, it's a completely irrelevant comparison (in fact, it's exculpatory).

> Theoretically it would if the American populous, heavily armed as we are, had any chance whatsoever against the military. We don't, so the point is moot.

You're imagining construction workers and commercial airline pilots and physics professors against professional soldiers. Imagine 500 professional soldiers with the backing of 5000 construction workers and commercial airline pilots and physics professors take over the military base where those 500 soldiers were already a quarter of the garrison, because the 5000 already had their own small arms and knew how to use them.

Then they have tanks and planes and nuclear weapons and popular support and the same dynamic plays out at ten other military bases.

Democracies are stable because if you have enough people behind you then you can vote the bums out before you have to fight them militarily. But authoritarian "democracy" where you have a central government imposing controversial laws with only 51% national support and significantly less than that in specific regions is more than a little unstable.
This is why campaign finance is the #1 problem facing American democracy today. It's not about the election, it's the re-election. It's about the sausage-making. Even if you come to Washington without the support of wealthy donors, you will have to work with people who do. Representatives in the pockets of special interests will favor them because those are the groups that truly hold politicians accountable, because losing re-election is akin to flushing a political career down the toilet. So policy tends to favor the special interests, even when the popular majority opposes it.

I do not believe it is possible for a powerful state like America to avoid corruption, because high concentrations of power insulate themselves from accountability (which is a threat to power like any other), and it takes immense power to reap immense benefits (whether those benefits reach the general population or are at the expense of others is a different story, like the CIA-backed coup in 1950s Guatemala which broke the back of local communists/socialists and ensured greater profits for United Fruit Company and lower costs to American consumers).

Therefore, I advocate a citizen's veto amendment, allowing the public to reject laws passed by representatives who only give a damn about the constituents during election season. If corporations and wealthy individuals are going to control Congress and the Executive, the people ought to retain the right to say no.

I predict a twitch stream of an AI playing various games. Watching it fail and succeed on various games and situations would be very interesting. Maybe a couple devs to do a voice-over.
I've read up and down on that issue because I have problems with my lower back and after reading many many reviews I decided against the Aeron.

The problem I've read of is the hard "lip" on the front of seating area which according to some reviewers tends to cut blood flow from the legs for longer sitting periods.

The Embody should be fine in that regard (from what I've read, but I haven't tried it - neither have I tried the Aeron).

I ultimately decided for the "Steelcase Leap" and from my experience this was the best investment I have ever done in furniture.

Before the Leap I was unable (and unwilling) to go sit at my computer after leaving the office - now if I get backpains while at work I cannot wait to get home and into my chair. This may not be the case for everybody but for me it reliefs my backpain.

If you're going to invest in good chairs, give the Leap a spin.
I've never understood this American thing of giving weight to the opinions of comedians on important matters.
I wouldn't find enough value in this to pay.

Yeah I think it's particularly bad in the US, where society has "advanced" to the point where the attitude of "there's a pill for that" seems to apply to pretty much any life setback.

Of course I oversimplify; I know not all people/doctors/regions are like that.

And I do see some of that kind of attitude among some in Australia too, but societal attitudes and the government controls on pharmaceuticals that exist here and the U.K. keep things more moderate.
Many tasks had been grabbed in the last 2 hours since this post is on HN front page, however I still see several available tasks. Do you see it totally empty (which implies a bug) or by empty do you mean "just a few"?

Processes can communicate. I reckon you could have a process that's responsible for managing the cache instead of managing a separate cache from each process.

I'm no Erlang programmer, though.
Yep. Except: please don't think of them as "method calls" :-))

"Smalltalk is not only NOT its syntax or the class library, it is not even about classes. I'm sorry that I long ago coined the term "objects" for this topic because it gets many people to focus on the lesser idea.

The big idea is "messaging" -- that is what the kernal of Smalltalk/Squeak is all about (and it's something that was never quite completed in our Xerox PARC phase). The Japanese have a small word -- ma -- for "that which is in between" -- perhaps the nearest English equivalent is "interstitial". The key in making great and growable systems is much more to design how its modules communicate rather than what their internal properties and behaviors should be." [1]

My contribution towards this is Objective-Smalltalk[2], where I am working on making connectors user definable. So far, it seems to be working.

True AI will never exist. It's just a fairytale told by vain blowhard liars to VCs who have too much money & not enough IQ. All that AI does now is build thoughtless goosestepping monsters slogging cluelessly thru digital bogs, with their dreadful simpleminded APIs, rigor mortis like tasks and tunnel vision so narrow and dense that even LOLs can't escape it.

Forget AI, we'll all be dead before we can even get something as mundane as a petabyte flash drive.

No greatness, no vision, no innovation - just turd polishers layering the same old pig with yet another colorful shade of lipstick.
I took the main meaning to be that societal problems were being solved from the wrong end, by changing people (forcibly, even) instead of changing society.
If you're speaking tools and frameworks, yes, but core data structures, algorithms, and paradigms change very slowly. Andrew's course focuses on the latter, basic ML techniques that have been used for years and will continue to be used for years to come.
But the publishers outsource the same work to referees. Why not cut out the middle man and have the funding agencies orchestrate the peer-review? That's what they do for grants anyway.
Why in the world would I want to do that at the wake?

That was your answer to the question I posed. You keep wanting removed conversations- that's the easy part. The hard part is what do you say when you have to look someone in the eye and explain yourself.

But the problem is that, while the President gets to see these numbers, we the people don't. They're secret. So the decision can't be made as a public decision where we can have a debate and then vote.

Precisely! That's why we have to be willing to discuss it also. Otherwise they have to make the determination and we all get to sit back and throw rocks at them. That's easy and cowardly for us, and not really good for them.

Also, phrasing the question as "how large must X be for the program to survive" forecloses the possibility of finding other ways to save the same number of lives, without sacrificing everyone's privacy.

No, nothing about this is mutually exclusive with (to?) working on better ways to keep us safe that help us keep our privacy. Of course, it would be difficult to regain that privacy, but I would definitely want sunset clauses built into any program or laws the I (as President dhimes) would sign off on.
It's even worse if you represent the primary numbers in binary notation. Every prime number greater than 10 ends with the digit 1 ;) [edit typos]
Perhaps I have missed something, but the introductory example seems to follow from simple probability and therefore I do not find it mathematically remarkable.

Say, there is a fixed and equal probability that each number ending with 9 and 1 is prime. I could go along with that assumption, although the fact that primes get less likely as you go higher is potentially relevant.

What the authors consider here is starting with a prime ending in 9.
So the next potential prime ends in 1. If only because 1 is the next number to be checked, a 1-prime is more likely to appear next than a 9-prime. The probability of that can be calculated, depending on your assumptions, as a geometric sequence. In any case, P(next prime is 1) > P(next prime is 9).

"Most mathematicians would have assumed, Granville and Ono agreed, that a [known] prime should have an equal chance of being followed by a prime ending in 1, 3, 7 or 9" So - I'm a definite nope on that.

This result appears to be exactly what I would have assumed was the case.
I could be wrong but I don't think this was really a thing until Jon Stewart. And some would point to him going on Crossfire (a 'real' news show) and destroying their hosts as a turning point in his being a credible voice.
It's because comedians tell jokes, but the mainstream media is a joke.
As I mentioned in a sibling comment, the INES just specifies that the accident required countermeasures to ensure public safety. That's pretty terrible; agreed.
Do they? Do you have evidence to back that up?

As others have said, Erlang processes are not OS processes, nor are they Java threads. They're closer to Go's goroutines or Python's eventlets; they are well-suited to run even a single function concurrently.

In the analogy, it's like having 2M web servers, but where only, say, 1000 of them are actually running. As a developer having independent web servers helps you to think about what should be done instead of how it's going to be done. After that, the fact that a server is actually running or it is stalled because it's reading from disk or it is waiting for available CPU is an implementation detail and something that monitoring will show you.
One thing to consider is that we can build the index on AWS and then only do replication with other datacenters at the Elasticsearch level, which is ~50x smaller than the raw data.
