I have experience of performers, when not accompanied by a piano, choose to perform intervals closer to 1.50000 than 1.50001, so it seems they prefer them.

However, the answer is more complicated than that. Quoting directly from my acoustics textbook:

"Research on the intervals played or sung by skilled musicians shows substantial variability in the intonation from performance to performance. These variations are frequently larger than the differences between the various tunings. Studies of large numbers of performances have shown that deviations from equal temperament are usually in the direction of Pythagorean intervals (Ward 1970).

"Several investigators have found that performers tend to stretch their intervals (including octaves), even when unaccompanied by a piano. Many choral conductors prefer the third in a chord slightly raised, especially in sustained chords or cadences, to avoid any suggestion of 'flatting' the chord, a particular nemesis of choirs. How much of the apparent preference for sharpened intervals is due to constant exposure to pianos with stretched turning is difficult to determine."

The Science of Sound, Third Edition, by Rossing, Moore, and Wheeler, p. 187.

(Ward 1970) is "Musical Perception" by W.D. Ward, in Foundations of Modern Auditory Theory, Ed. J. Tobias.
Why would you want to do these in a UI instead of scripting/automating them?
That depends highly on your team. If I have 20 support people with access to GH, but no coding work, the cost factor is not the team size. On GH enterprise, that's another kind of math. There's certainly also projects that just run in one repos for ages (long live the monolith).

Also, with GH, I can always choose to take a project off GH and archive it. That wouldn't make sense if it were user-billed.
To put that in perspective, pretty much anybody can distinguish a pitch difference of 25 cents. People with perfect pitch can distinguish differences of less than 10 cents.

Anecdotally, when I was taking lessons with my old cello teacher (who has perfect pitch), if he and I played a note on an open string simultaneously, I could always tell if we were in relative tune by the way the notes interfered. I don't think I'm particularly special in that regard.

Edit: Also, once I have one string tuned, I can tell if a neighboring string is correctly tuned because neighboring strings differ by fifths. Again, I don't think I'm particularly special; it's just a matter of learning what to listen for.
It does depend on the style of music, but it's easy to notice the clash between piano and violin tuning in, say, a slow movement of a Beethoven or Mozart piano concerto. In particular, it's the sharpness of the major third on the piano that can makes a noticeable contrast with what the string players are doing. (string players know all about this, pianists have to put up with it):

(http://www.violinmasterclass.com/en/masterclasses/intonation)

Perfect (absolute) pitch can sometimes be a blessing, sometimes a curse. I don't have it, but my partner did, and she struggled to enjoy some concerts that I enjoyed, simply because the notes from the various players weren't aligned well enough...
Cool! The idea of filesets is very nice - there are some very interesting workflow ideas buried in there. I've been looking forward to a mainstream unioning filesystem for a while too - and I hope rocket does some serious exploration (or enables it) of how to take advantage of them fully in both development and deployment. (And while I'm at it, testing too).

My personal wish-list down this path includes:

* options in the relevant manifests on which layer is writable ... if I'm doing development on libfoo which is used by several different apps, let me make that layer writable so I can rapidly iterate integration tests and (bad practice) live coding on testing/dev servers.

* tools to help me smash a dev layer or 3 into a single fileset (and similarly dissect a layer into a few new filesets during a refactoring)

* the ability to use filesets and overlays in a way similar to package management is now, but with extended features that are similar to python's virtualenv.

One of the things I see as a boon of the filesets as described is: I can update parts of my system without having to rebuild the whole dang app silo from the get go. Combining this with some of the above features looks like it could be useful for making "thin" images - where I can build all my code in one place, and port only the binaries to the staging and deployment images, just by doing a few fileset/overlay tricks. (no more complicated scripts)
The discrepancies mentioned in the article are rather larger than 1 part in 15000 and can be heard quite easily. I'm not sure what the lowest difference the ear can detect is but with two notes played simultaneously you can get odd beat effects as the notes go in and out of phase. Say the two notes produce harmonics at about 5kHz, then if they are out by 1/15000 then they will go in and out of phase every three seconds and vibrate the ear drum more when in phase than when not so you may well notice.

You can do an unconditional jump every 1 or 2 cycles, depending on the chip, whereas no chip I know of can execute more than 4 nops per cycle. Therefore I would say the jump is probably marginally faster than 12 nops.

Smart toolchains will turn those 12 bytes into 2 multi-byte nops, e.g., a 9-byte one and a 3-byte one.

I'm not certain what aspect of my reply you're disagreeing with. Are you saying that it's not true that we've been maintaining the ability to fight more than two wars? Assuming that's the point...

Your reply seems focused on the quantity of soldiers. This is an important factor, but I was primarily considering overall spending, which obviously includes lots of capital expense, logistical stuff, etc., aside from the personnel. I believe that the level of investment in military hardware and the like is significantly higher than would be required for a successful war on two fronts (assuming that there exists such a thing as "successful war" these days).
Isn't it strange that there is still no career path from nurse to doctor? Medicine is still a closed shop.
This is a good article, and the constant need to code bigger bowls of spaghetti faster is definitely a problem. However, I think that it's a stretch to imply that only older engineers do this.

There are many billions in lost treasure alone on the ocean floor. "Late" salvage is not typical but also not unusual as technology makes it easier to find and possible to recover wrecks.

Legal obstacles seem more difficult than technical ones these days. See Odyssey's legal battle vs. Spain for example.
If the laws are on the books and applied in a non-arbitrary way the perception of DUI might change - after all you want people to be sober behind the wheel even when the police aren't looking. Unfortunately, in the US, you can't breathalyze everyone on a Saturday night, you have to have "reasonable suspicion". Which means that on weekends, the roads are less safe than they could be, I avoid driving on the weekend after dark.

I went to UGA my freshman year. Compared to other campuses where the parties are at fraternities or private residences, Athens is a bar (and, as the article points out, a fake ID) town.

It was very much a wink-and-grin environment: the "bad photocopy job pasted onto a McDonald's gift card" description is very apt. Some bars were tougher than others, but for a guy, showing up with a favorable distribution of girls would cause the bouncer to look the other way.

It's obvious and egregious (UGA suspends open container laws on gamedays), but as the article's subjects and other HN posters point out, the problem is not bars and fake IDs, and more college students' drinking problems. (Which exist at fraternities, house parties, and other venues as well.) To that end, I laud the focus on safety, education, and one-strikes over just pushing the "scene" underground.
Wanna see a cool visualization of the question you propose?

This is NOT what your eardrum looks like when you hear notes in tune, but it does provide a certain visual simulation of why simple integer-ish ratios sound better than random ratios.
I remember there was a bug/trick/cheat by going up hill underneath a ski-lift you would basically get infinite points.
I used to take cello lessons, and my teacher had perfect pitch as well. I used to tune beforehand to A=440hz, but he kept having me tune higher. I was puzzled as to why until I asked and he said he tuned to A=445.

One of the lessons I learned was that it's better to be relatively in tune than absolutely in tune (i.e. tune to the soloist no matter what), and it's moderately better to be sharp than flat if you're going to be out of tune.

Which may also be influenced by the probability of 800 miles away being another country (with an entirely different language).
My trouble with these things is that they invariably support multiple services, all of which I have accounts with, and I can never remember which one I'm using for any particular service.

But others don't have to buy the US treasuries. They can diversity - China's beegun more aggressively pushing theirs, France recently got pisset at the US and may diversify. Russia is cutting ties with US banks, etc. I am not sure why you think the worldwide market simply doesn't realize that the dollar is going to get devalued in the near future, and with it the coupon payments. Countries compete on many levels including their currenxy, and in the market, the Fed sells treasuries at a favorable interest rate.

In the United States since 1959, banks lent out close to the maximum allowed for the 49-year period from 1959 until August 2008, maintaining a low level of excess reserves, then accumulated significant excess reserves over the period September 2008 onwards. Corporations began sitting on their cash. So money is being allocated towards other things than jobs and investment in local wages, which have been stagnating for decades, and given a boost by the consumer credit explosion of the 80s and 90s. The money is being offshored, globalization and automation have caused the American worker to participate in a race to the bottom with the rest of the world - this mean reversion helps billions of people around the world but undoes the dominanxe the US has enjoyed thus far. Supply chains now stretch around the world. Apple offshored its money to avoid taxes for one thing. Amazon employs robots now, and its wage slaves are interchangeable etc. I see structural problems as being responsible for the slow recovery the US, not Fed policy.

Although I would probably agree with you in one thing - a direct unconditional basic income for US residents would do much more long term to revitalize the economy and lower misallocation of resources, than giving it to banks.

You can use two or more DNS providers, but if you do try not to list more than two name servers from any one provider when you delegate. You should also take care to do the same in your own zones "NS" record set. Some providers don't let you change the NS record set, so avoid those providers.

The reason for this is that resolvers will generally try at least three different name servers before giving up, so if you have three or more from a single provider that may not help.

There is also a big caveat to consider: once you use two more providers, whenever you need to make rapid DNS changes for your own availability reasons you will need to wait for the slowest-to-update provider.
This looks like it'd be really useful for quickly making teaching materials.

Currently the auto-updating feature only reminds you to download an update. It doesn't update itself silently. And you shouldn't edit your production data directly anyway (or at least you should try on a dev server first), right?
This is awesome.

This is also the kind of enterprise/b2b open source project which you can reliably* turn into a $300-500m exit in ~5y or so. Covers a clear pain point, has clear revenue model, can sell packaged version and support.

That was a really great read.
There where actually a wide range of effective treatments for infections before antibotics. EX: Hunny works as a topical treatment. Dioscorides (c.50 AD) (http://www.worldwidewounds.com/2001/november/Molan/honey-as-...) The problem is Aging is a single word discribing thousands of individual problems. It's like someone saying they can solve 'network secuirty' with a simple patch. Cancer is a similar issue because what's being discribed is a symptom not a unified underlying breakdown.

EX: Cantagious cancer: http://en.wikipedia.org/wiki/Devil_facial_tumour_disease

On the other hand we have zero effective treatments for aging.
Maybe. But I would like to see how it goes before open sourcing it.
Tobi is the one that taught me Rails back in 2004 when it first came out.

He told me he was working on some new thing called Shopify, but I didn't believe in it.

Later he asked if I could introduce him to Tim Ferriss, and I had to politely decline, because I didn't think Tim would be into it.

Now Tim is an investor in Shopify, which is a huge success, and I'm so happy to be so wrong, as usual. ☺
I'm guilty of this and have edited down as much as possible with 6 positions that opened up.
Where's the critic of Rocket ? All I see is that they disagree with the choices made by the team behind Rocket and they want to blog about it later. Other than that, Ben seems to only say that Docker was built by and for a community of developers and devops to make applications run consistently on different platforms. Ben says that expanding the scope of Docker is the right choice despite people being opposed to it, if I understand him right.

No, I'm not a Docker fanboy. Yes, I think Docker is pretty cool. Yes, I think the competition from Rocket is great and I can't wait to see how things go.

Really? This strikes you as a good idea?
DNS is so straightforward, so easily distributed, and so fundamental, that I'm always astounded when it's a single point of failure for so many operations.

I wonder how many of the affected companies do have redundant appservers and load balancers, but missed this piece of the puzzle...
"username or password incorrect" does not imply that the username was correct or incorrect. The system is saying one or both fields are incorrect.
Yep, we have plans to improve the noise and echo cancellation. It kind of works at the moment, but should be much better. Also the quality is not uniform across the platform, which is another thing we want to fix.
I love Oliver's posts every year. His 2013 series got me into Haskell. I'd forgotten about this series until I saw it on my rss feed this morning. Very excited.
How to start small
It's part of the decay chain of U238 which is present in trace amounts in much of the earth's crust. I would imagine it's nearly impossible to chemically separate it from the lead. Would require a process similar to that used for enrichment of U235 but economically not worth the cost.
Yeah, at least for my building (which I'm heading up the internet committee for), the BPON that was installed by AT&T can do max 600 Mbps for about 30 customers on a loop, so that's 20 Mbps each. They should be able to burst higher than that when it's not saturated, but they haven't bothered to turn it on.

If you're in our building, you're in luck, though: the HOA is amenable to laying CAT5, so if things go well, we may have Webpass by the end of 2015.
It doesn't work that way for me - for some reason the syntax makes a huge difference in my productivity and level of energy.

Coffeescript works way better than JavaScript, Elixir better than Erlang, Slim better than ERB. It shouldn't make that much of a difference, but it does.
I really like that analogy but am not sure if that's what the author was alluding to.

Besides the one thing I strongly disagree with is how typing slow can help you produce better software.

Taking time and thinking about your design certainly does help but typing slowly and taking your time designing are not the same thing.
For those with a more deterministic bent: "propagation" time has a maximum bound of your TTL, which will show with any dig queries.
At least in my experience, the main point of coding interviews has always been to expose and analyze the way that you approach and solve problems, not to see how fast you write code. It's usually better to take a step back and re-evaluate the design of your solution rather than dive into the first solution you create, since you'll usually find a better way to express the solution that is short enough to write down on the whiteboard without pressing against the time constraints.

It's also important to see how reliant people are on their tools.
Has anyone read this book and for those who have is there a correspondence here?

Thank you for your feedback. We're currently working on a docker container for Weaver, and we'll publish again once it's done.
It's not paradoxical at all. I think that the more syntax you have (thus shortening the code), the less you can reason about what you write while writing it, because the mental overhead of writing itself goes up. Compare stenography to latin in that regard - stenography is almost never used to write down ideas, only to transcribe.
clearing up some facts.. warden predates docker, its a container impl. diego is something entirely different more like kubernetes or mesosphere (scheduling & health, etc). garden the go implementation of warden containers does add fs compatibility for docker.

While that may be true, timing your solution of an issue at a whiteboard isn't necessarily representative of your 'ability to ship on time.'
