Some of those languages are more functional than others. The Scala creator claims it's 50% imperative 50% functional. Others of those, e.g. C# and Groovy, are closer to 10 or 20% functional.

Just like the amazing amount of StarCraft glitches, ranging from making ground units fly to completely insine stuff like turning a unit into a trap that crashes the game for every player who looks at it (and after some time crashes the game for everybody). All by legal in-game actions. I can't find a link, but one comprehensive summary back in the old days suggested that at least some of those glitches may be intentional, given how improbable, weird and useful they were.

Anyway, an example list: http://www.entropyzero.org/Glitches.html.
You're not going to beat the two-nodes price. If you're fine with a single-NIC single-disk server, Minis are not a bad deal.

However, you're not going to get dual-NICs, ECC memory, or multiple "spindles" in a Mini formfactor.

Ask HN: solving mobile app discoverability - a major opportunity?
Mobile app discoverability is a major problem - application developers find it hard to become visible to end consumers. This leads to problems where a small number of more visible publishers get the lions share of the revenue http://www.forbes.com/sites/chuckjones/2012/12/06/top-25-developers-receive-half-of-app-store-revenue/

Is there a major opportunity in solving this problem?

Put another way, are we at AltaVista level of search engine for apps, but no one has yet come up with the Google of mobile app discoverability?
I had no idea they needed money until I saw this here. I went straight there and gave them some.
Everything. It is all in one place, very simple to use, has process monitoring like Monit and well supported.

Nobody uses what Apple ships by default. Homebrew or MacPorts and I have exactly the same setup as I have on my Linux server. Plus lots of amazing GUI wrappers which can simplify setup and ongoing maintenance.

I run a music website on the side that I'm now completely rebuilding with a tweaked a concept (a pivot, if you will) that will be geared towards creatives and maintain by userbase -- I've had about 13,000 signups over a long period of time. When I relaunch I'll have to go through the same thought process as you, but first let me tell you what I've seen so far.

At my day job, I've run millions of dollars in paid user acquisition and lead gen. What you have to realize is that when you're paying for users, you're normally not going to get more dedicated users (simply interested people). Organic users are usually higher quality leads than users from paid user acquisition because they came to you as interested potential customers rather than you convincing them through marketing messages and a well thought-out and optimized landing page.

Paid acquisition can work really well for companies that have a high lifetime value for a customer (LTV). That's why you see ecommerce companies, for-profit colleges, insurance companies, and other similar high-priced products spending millions in the display, social, and SEM space.

Then you see the Groupons and Living Socials of the world going for a landgrab of users quickly (paying millions to acquire users at a moderate price). But that moderate price still might not back out as the category gets less sexy. You barely see ads on Facebook for these companies anymore because the cost of acquisition is simply too high.

If you're going to do paid marketing, you have to really know your business and how you will monetize your site/app to make some decent margin at the end (selling data, premium subscription, advertising, etc.). I would only use paid marketing to validate interest on a very small scale or as a small push at the beginning to gain awareness.

If you're an app that requires a lot of users who will each monetize at a small amount, you need to have a stellar product with some other distribution mechanism (partnerships, viral coefficient greater than 1, unbelievable PR machine, etc.).
Inspired, not directly modeled, I think. Dr. Strangelove was in part based on Edward Teller. Unlike von Neumann, Teller actually a bit bonkers in many ways; he was a deeply jealous and vindictive person who was directly responsible for destroying the career (and likely shortening the life of) J. Robert Oppenheimer, and he tried to convince people that Stanislaw Ulam did not contribute to the Manhattan Project. Teller wanted to use hydrogen bombs to dig deep-water harbours, and to extract oil by blowing up underground oil deposits with nuclear weapons, and lobbied to create what became known as Reagan's failed "Star Wars" project. He also tried to get the US to build a network of underground shelters similar to the scenario that Dr. Strangelove outlines at the end of the film.

I'm listening to the series now. One of the oddities which struck me is how psychohistory could predict the microminiaturization of nuclear power cells. Nuclear power had been known for about 15,000 years, but only in the last 200 hundred was there a specific need by a resource-poor planet to figure out how to make those things, and so they did. Yet it was essential that those power plants exist in order to power the trade goods and the personal shields.

Sure, the Empire thinks in terms of large scale, but there's always a need for small, energy dense power systems. I can't figure out why they didn't exist already. And even if they didn't exist already, I don't see how psychohistory could have predicted that it would exist.

While on the other hand it makes the prediction that nothing will replace the standard jump technology for interstellar travel. If there were a way to go from Terminus to Trantor in, say, 1 jump instead of many, or if they could be done much faster, then the dynamics of the civilizations would also change in quite unexpected ways. There would be no "edge" of the galaxy, for example, since every planet would have about the same travel time to the other.

How can psychohistory make that prediction? More importantly, by the end of the original series, the "Lens had performed a near-revolution in interstellar travel", making hyperspace travel much faster. How could psychohistory predict that it would exist, much less when it would arise?

Either one of these - the lack of small nuclear power sources, or earlier creation of the Lens - would make big changes in the Foundation. And big enough changes that there's no way it would get to the same sort of semi-stable attractor as the alternative.

My experience ordering a Nexus 4 was a bit of a farce: Google managed to trigger the anti-fraud block on both of my credit cards, each with different UK banks. It looks like they put through a small value transaction (£1) first to test whether the card works & only then put through the full purchase transaction.

Why they can't just put the transaction through in the first place & just report back if it fails I've no idea, but thanks to Google I had to phone up the respective banks to get the cards unblocked. Not the best use of anyone's time...
There are no people who don't lie, and there never has been. To believe otherwise is to lie to yourself.
I was surprised that the code of conduct was all about what you shouldn't do, instead of what was expected of the attendees.

Telling adults, "Be careful in the words that you choose." does give the code the Code a patina of Political Correctness. I was half expecting the next paragraph to warn me to look both ways before crossing the street.

The Code has a very broad definition of harassment that makes no distinction between a one time comment and a pattern of repetitive behaviour intended to intimidate or cause harm.

I see that "following" is one of the actions that defines harassment. How does that differ from stalking? I assume they are not referring to Twitter.

From what I understand, the code was approved by the Board of Directors of the PSF, and not the PSF as a whole. Please, correct me if I am wrong. This is ironic since one of the Board members was walking around the conference last year with a damaged stuffed python toy asking, "Would you like to see my one eyed snake?"

This was said to one of my female colleagues. I asked her if she would like me to say something and she replied, "No, it is just creepy, but I'm an adult."

The Board's aspiration to create a welcoming environment is laudable and this spirit is very much a part of the Python community. I don't think that the Code, as worded, helps accomplish this. It is overly broad and loosely defined. The result is that it sounds like an attempt to infantilize the attendees and proscribe behaviour that may be part of vigorous exchanges of points of view.

I am sure that this is not what the Board intended, but you would wish for a more articulate expression from a group of engineers who would not tolerate this sense of generality in their code.

Its a literary of little things that kept adding up for valve to make a move in this direction.

The big ones for me have been the fact that valve has been hiring hardware, dsp, fpga, linux developers, kernel hackers, control chain specialists and such forth for the last 2-3 years.

I remember saying a long time back that valve are either going to push onto some android hybrid thing, or that there were making a console.

I think the Linux thing was valve reacting to windows 8 that forced them to show their hand a little.

I do not see any reason to suppose this is true. I grant that this is question that is not being tackled by current research (as far as I know, as neuroscience and theoretical neuroscience are in a period of boom right now), but that does not make it scientifically intractable. There is little I can say about this as I do not know what you mean by "the actual experience".

Good post, but one major flaw in the comparison to carpentry:

"It doesn’t matter how many years experience in carpentry you have had or how well you can design furniture or cabinetry if every time you try to cut wood you struggle with making the cuts."

That's not even close to a legitimate comparison.

Cutting wood is a tactical, known activity. You learn how to do it, and you always apply the same known, proper technique.

Problem solving, by definition, means you don't have a stock answer to deal with. You are effectively inventing a solution and drawing on your experience. Worse, you invent a solution each time.

If he wanted to make a more accurate comparison, I would say declaring a variable or writing a for-loop is the equivalent of making a cut. Irrespective of the problem, those are done in standard ways and you just have to know how to do that.

For those wondering/questioning this line of thinking, compare the following:

--turning a bolt
--putting an engine together

Those are two very different things. Or,

--cutting wood
--constructing a house

Again, two very different things.

And I won't even factor in the idea of knowing how to do something "software developer related" in a few languages and/or a few frameworks.
I've mostly been googling for studies/information which explain things I do not understand. Most of the studies tend to be on Pubmed (www.ncbi.nlm.nih.gov). A lot of references can be found on wikipedia, which is a great resource in itself.

This is paired with playing with neurotransmitter levels using the methods described (and occasionally some less legal ones) and trying to relate feeling to thought. After a while, an intuitive understanding of the terrain that is the body, thought and emotion begins to emerge. Sometimes you feel something new, notice an interaction, make a prediction that neurotransmitter X has relationship Y with neurotransmitter Z, google for studies and are surprised that said relationship has been observed. Intuition is as accurate as the information it's working with - it can sometimes be trusted and other times cannot. I'm a programmer and to me this feels identical to debugging in a messy monolithic legacy codebase. I use the exact same techniques to try to figure my mind out.

I think that it is important to be picky about sources. I do not trust anything which cannot be backed up by a study, though less accurate information can sometimes point you somewhere interesting. I also find it important to tread away from the mainstream with caution, since I'm not an expert in this field. In other words stuff like Reiki is out of the question - it needs to at least be feasible.
IIRC, ESPN is the most expensive and some of the channels are actually free. If there is information on the history of Telebeam (and how they started), it might be instructional with regards to picking a niche and starting small.
Out of curiosity, what's the problem with that? I assume he'd have the copper twisted together to make a good connection, with the solder just holding it in place instead of acting as the conductor.
I'll be the one who says it... There are too many typos in this piece (including the first paragraph) to take it seriously.
Unless I misread something that is a single node. The key point about the Mac Minis is you can have TWO nodes in 1RU. And given that the data centre costs will be more than the hardware it makes the overall proposition very compelling.

It's a niche use case, but Apple's Qmaster software facilitates distributed video rendering and exporting for Final Cut Pro and some of their other pro applications. A server cluster like this would probably be overkill, but when you're working with massive video files, extra (OS X) machines to do the heavy lifting make a huge difference.
Stealing personal information from the tax authority for years? I consider that rather serious.

Not on the level of killing someone or some such of course but in terms of potential damage to many it ranks rather highly.
OK. If you just want the technical details:

* FreeBSD supports ZFS, whereas Linux can't really due to license issues. (Although people have tried-- please don't reply to me saying "but XYZ got it to run!" It's a legal issue that's not going away.) However, Linux has btrfs, which delivers a lot of the benefits of zfs. However, btrfs is not really at the same level of stability yet (although it may get there soon.)

* For its audio drivers, FreeBSD uses a descendant of OSS, whereas Linux moved to ALSA and later PulseAudio-over-ALSA. I have heard claims that OSS4 provides lower audio latency. I am not an expert so I cannot evaluate those claims. On the other hand, Linux also has JACK, an alternative sound API which is supposed to fix some of the latency issues of PA+ALSA.

* The original version of Rubberhose (the deniable encryption filesystem) was written for FreeBSD by one Julian Assange. I don't think it's still maintained, though. There was a version for Linux 2.2 at some point, but good luck getting that to compile in this day and age.

* Linux in general has a lot more APIs between kernel-space and user-space. In Linux, you've got procfs, sysfs, debugfs, netlink, and so forth. BSD was a lot more conservative about adding APIs.

* The FreeBSD jail mechanism is pretty good. Linux has seccomp, SELinux, SMACK, Tomoyo, cgroups, and so forth, but none of them are as easy to use as jails.
The Five NYC Taxi Drivers who Refused My Fare
I learned Unix and C on a Model 16 (which was actually very old by the time I got to play with it).

When, many years later, I found that I couldn't test out of my college's C programming course which was a prereq for a CS major, I sighed and showed up for class -- with the exact same dog-eared copy of K&R 2nd I'd used to attempt to teach myself C on the old Tandy.
I'm actually surprised any DC would take that equipment. They, in my experience at least, are very fussy about what what you put in the racks and power draw etc.

Oh and we get 640 cores in 20U (8x4 core xeon machines each 1u) and that leaves enough room for a 32Tb SAN, FC switches and a pair of redundant LAN switches.

What would the licensing repercussions of that be, if any?
Could anybody explain why there is such a difference between text and image? Is this just because the file sizes are different or has that a different cause?

I really like to "out-of-the-box" comparison, but as others already have stated for apache that doesn't really make sense because apache just doesn't perform well without any configuration changes.
Yeh that's why I said ~15-20% - it varies with IV, I just take a different spread than exactly +/- 20%. Fundamentally I don't want to be exposed to black swan downside, and black swan upside is statistically rare - so I don't mind losing that (things don't move up 30-40% in a month too often - manias/booms are slow - but they have moved down 30-40% crashes/panics -> bull markets are slow, bear markets are fast - and that is the asymmetry I'm exploiting to cap my risk without negatively effecting my return - selling covered calls is effectively free money most of the time, and buying puts covers my ass from Enron like events and the asymmetrical movement between booms/busts/disclosure negative information like bankruptcy).

>This business where literally everyone who replies to disagree with me only looks at absolute numbers is getting pretty irritating. It just makes no sense.

This is a learning moment. Other people are using different assumptions about war and how to measure it maybe they have something to offer you in perspective.

For example a war is not merely summed up by number of peoples killed nor is it understood by the chance that a single person at that time period might be killed or the total world population killed. In fact the level of war or numbers of wars could increase dramatically without any increase in violence by merely varying the culture, technology and other circumstances.

You did not address the fact that the source you cited for your argument supported my claims and not yours. Have you cast Pinker and Goldstein aside? If you still agree with Pinker and Goldstein then you agree with the claim I put forward and I'm not sure we have much more to talk about. If you don't agree with Pinker and Goldstein, why not?

Expressing how irritating or annoying you find the people with whom you are having a discussion is rude. Why do you think such statements are a good strategy?
