>However, all I'll say is, it's very different to hear or feel a difference, than to prove it 100% without any doubt in the exacting conditions of an ABX test. You behave differently and aim your listening at different things in the special case of critical testing, than when normally listening.

so what you are saying is you know what sounds better if you read the label BEFORE listening to it? :)
There is almost always a difference, no one is claiming otherwise. Pointing which one is closer to the original (not "better", because "better" might mean louder/overdriven bass) is the real test, and EVERY SINGLE audiophool to date fails at this point - Randi foundation did run a $1M pot for someone to spot a difference between 'audiophile grade' power/speaker cables versus coat hangar at one point.

>People flooded into school thinking "school is a safe place to hide during a recession". This led to large crunches every subsequent year.

Another data point is NYC Business Schools. Lots of people in finance applied to, say, Columbia business school during the crisis, and thus around 2012 there was a huge plummet in applications there as the industry (a) started to recover a bit, and (b) it became clear that the rewards from a career on Wall Street would be much smaller than in previous decades.
The big distinction here is "Top 15 Law School". Almost any law school that isn't up there is basically a scam. As the law market contracts, I'd imagine that the employment prospects of top-15 schools will shielded the longest - law firms that previously couldn't hire great lawyers will realize they can hire better new lawyers once it's harder for those lawyers to get a job.

My brother is at NYU Law and has a starting job next year with a starting salary around 170k. From my understanding, kids at NYU are still not struggling (at all) to get decent jobs after law school.
I think chanting "talent shortage" as many Silicon Valley tech companies do is hurting the immigration reform cause rather than helping. Also lobbying to increase the size of the pool makes no sense - it's just going to get fill the insatiable desire of body shops like Wipro, Infosys, TCS etc that are the main cause for tech salary undercuts -- by mass importing workers who jump ship asap willing to take low pay.

One of the things we really need is for a skilled graduate or immigrant to be allowed freedom of employment. This stops driving salaries down, because employees then aren't bound to an employer to get their green card or maintain their legal status (giving the employer freedom to put the salary where they want because of desperation). Yes, the H1B portability exists in theory, but in practice they're unusable - with only 60 days of legal unemployed time between jobs, having to secure a new offer before initiating the transfer process, and having any active green card application processes (which can take more than 5 years usually) killed if you transfer, we might as well pretend the portability option doesn't exist.

I would also like to note this reformed H1B shouldn't be awarded to the body-shop-type employers (basically anyone employing over 40% immigrants and over 100 people). Technically this clause exists today, but these body shop companies have a lot of phantom "US Citizen" employees to bloat their total employee numbers and then all the actual staff is imported. Those practices need to be audited more closely at least for the larger companies and curbed.

At the very least, I think it makes sense for someone who has spent 4 or more years in US in the capacity of a student to be given freedom of employability a little more easily, without restricting them to having to go to one of very few employees that can secure them a H1B visa now and commit the first 5-10 years of their career at that one place (or leave the country) to stop being treated worse than illegal immigrants.

More importantly, I think the process needs to recognize the fact that there is no room for company founders, other than the atrocious O1 process which is expensive and time consuming and subjective. I personally believe anyone who can demonstrate basic intent to create a job and shows qualifications for it (maybe after operation of the company for some period of time) should be given a visa with weird restrictions on salary and job title and whatnot, with an audit clause for every 2 years or something. All the existing visa programs are extremely constrained for most founder circumstances (which are quite varied, because founders are supposed to be about finding creative ad hoc solutions).

> "map" and "reduce" are imperative; they order something done.

So maybe it's my age showing, but I was taught that imperative was using explicit variables to control the "looping" (e.g. for with an index a la C style programming) whereas using "higher order functions" was not imperative. And I tend to agree with that. So I disagree that map and reduce are imperative because they don't explicitly control how the looping is done.

Can anyone cite where map and reduce are imperative? Must be some new-fangled text book that I'm not aware of ;)

And I get that someone could impose on me to cite references that map and reduce are not imperative. Point taken and I'm thinking that I got this from SICP in the first place so I'm looking it up now. Will report back if I find anything.

EDIT: First quote from SICP:

"In contrast to functional programming, programming that makes extensive use of assignment is known as imperative programming. In addition to raising complications about computational models, programs written in imperative style are susceptible to bugs that cannot occur in functionalprograms."
PCM audio sampling is linear, not logarithmic.

There are log sampling systems - e.g. A-law and u-law are used in telephone codecs.

But uncompressed audio formats like PCM WAV are 100% linear. (Or should be, near enough.)
I just wanted to address your point that enterprise software does usually not involve dealing with numbers.

When it comes to integers you are right - signed and 32 bits is a viable choice in north of 90 % of all cases. And when I wrote you should be able to make good decision about the number type to use I was already thinking of all the number types, however I did not express this well. But then I really don't see a lot of difference between being able to choose between integer, floating point and decimal types on the one hand and various integer types on the other hand.

It's not reasonable to embed every possible language constructs, semantic and logic into a theorem prover. So the trick is to make the host generic enough to be able to embed your needs as a domain specific language: your critic becomes a library problem. Which implies that you only need to trust the host logic/implementation; and many people can work, collaborate and profit from the same core. Also, we kind of know how a generic logic can be done, but the domain specific logic are more controversial (because everyone needs are different.)

The fact that your DSL is represented as an immutable datastructure by the host is really not important. Any code you write is going to be turned into a datastructure at some point. The immutability should be read as "the context in which this result is valid has been made fully explicit", where "context" includes "things that mutate over time". You don't loose in expressivity, you just can't forget to handle special cases.
What is the interpretation to which you are proposing an alternative?

The article is correct, but it's not true that nobody can't tell the difference between an MP3 and a FLAC.

I've personally done blind A/B testing in my (then) studio to discover the point at which I can't distinguish between MP3 and uncompressed audio. These days the encoders are really good, so it gets real hard at around 256kbps. I'm confident I could reliably pick out 192kbps though.

Suppose the person who mixed a song was using beats headphones or other headphones that audiophiles consider inferior but that they know the majority of people use to listen to music. Wouldn't that then mean Beats headphones actually provide the listener with the actual, intended experience?

I've a pair of Sennheiser HD280's that knock out background noise passively better (their website says 32db attenuation... and I swear they are a sanctuary from sound) than a lot of active (as in powered) noise-cancelling headphones. They're also some of the most unbiased headphones I've heard at $100 (which may or may not suit your tastes)
I have to try the Beyer some time. Agreed on the Sennheiser ergonmics - and the price.

I can't stand the Sonys. They're specifically designed for tracking & editing - all that screech points up Bad Things Happening. But they fatigue my ears.

Laugh now, but I landed on the Koss KTXPRO1 ( which are $20 to $40 ) and have basically stopped looking :) Most comfortable thing I've ever used and they're actually pretty flat, except for a little bass bump and a smidgen of upper mid. I think I'm on my tenth pair. They're a bit too light weight - if you catch the cable on something they'll fly off your head.

And yeah - I bet the $500 vs $20 figures into my perception of things.

What Google.com Would Look with Material Design
First, I think this whole article was filled with useless advice. The only useful thing would be to talk about giving people better compensation. Maybe it wasn't obvious that I was thinking about equity+salary when I said "money". Startups have equity. Equity is a financial instrument. Equity would definitely be considered in any compensation package.

My experience is that startups are extremely stingy with equity. I honestly was shocked back when I first learned how little equity was given to engineers in general. So I disagree with your statement that it would be useless advice, if you also extend it to giving more meaningful equity to employees. Also, I've had salary offers from startups that matched offers from the big software giants. Startups have money they just have to decide how to allocate it. If they need engineers and they are having trouble hiring, they probably will have to offer a higher salary or lower their talent expectations. Or just keep the same plan and hope to get lucky.
Sure, but it might be possible to actually have the program if we don't.

A company can make a loss indefinitely, as long as they don't run out of money. While Elon Musk carries such a high personal net worth, and the dream of hitting Mars stays front and foremost, that means they can make a loss for a very long time...

For some reason, this all brings to mind the Keynes quote: "The market can stay irrational longer than you can stay solvent".
Rick Rosner IQ and Health
Firstly people haven't 'done this test over and over.'

There's been exactly one serious sort-of peer-reviewed paper in the AES journal, and that paper compared high-res commercially mastered audio sources of possibly questionable parentage with a 44.1/16 downconversion.

It also included SACD, which isn't a fixed bit depth linear PCM technology, and has been justifiably criticised for it.

I'm not aware of any tests that compare raw high-res unprocessed recordings with downsampled content.

Secondly, a fair comparison would be 48/16 and 48/24.

Personally I'm not very sold on high sample rates. I know there are technical reasons why it's easier to make antialiasing filters sound transparent at 96k than it is at 44.1k, and in practice it's not easy to pull apart practical design from theoretical limits. (Nyquist is only ever an ideal. No hardware is ever Nyquist-perfect.)

Basically psychoacoustics is hard. Ears are ridiculously sensitive, brains are occasionally delusional, and marketing people lurk everywhere.

It's extremely difficult to pull apart fact from reality.

But that's no excuse for having a misleadingly superficial understanding of the theory - which the original article does.
Of that group of STEM majors not in STEM, how many do you think could work in a STEM field after going through a professional masters program? Clearly, some do, but it takes a lot of money and valuable time. If under greater pressure, I'd imagine a lot more established tech companies would recruit with a masters program in exchange for a several year commitment. Some places do, but if it were harder to recruit, it is a fair guess more places would.

I'm not really sure what to think about those sorts of arrangements. If I were an employer, I'd greatly prefer skill-based immigration, excluding questions of exploitation, and that's the point, particularly when referring to STEM as a whole.

Asher Peres, one of the coinventors of teleportation, had an amusing story (with a serious subtext) about the question of what is teleported: "Later, when a newsman asked me whether it was possible to teleport not only the body but also the soul, I answered “only the soul.” Even that is a gross oversimplification."

http://arxiv.org/pdf/quant-ph/0304158.pdf

In teleportation experiments to date only some degrees of freedom are teleported. So it doesn't usually make a whole lot of sense to say "the atom" was teleported. Rather, it'll just be the quantum state associated to nuclear spin states, or electronic degrees of freedom, or whatever.

For myself, the desire to change jobs comes from the observation that the companies trying to poach me away are offering more money than my current salary even considering the foreseeable future of raises. I happen to like the people I'm working with, so I continue to stick around but at some point those numbers are going to get too far apart and I'll make a move. In my current company (very large), the prospect of raises and promotions are slow, small and far in-between. Maybe I'm in a weird place, but that's been my experience thus far.

> Furthermore, unless those exemplary charter schools are forced to take any students applicants (which seems contradictory to their "charter") as opposed to those who "qualify" or "via lottery".

Charter schools are required to take applications for anyone who wants to apply. They even take applications from outside the district. There is no "qualifying" for entry. However, as with any school facility, space is not infinite. One of the things that lets charter schools stand out is that they usually have smaller class sizes than the non-charter schools. They are not going to just cram more kids in. So if 1500 students apply for a school that only has room for 1200, then a randomized lottery is performed. I don't know how other charter schools do it but ours has the most opening for kindergarten (obviously), very few spots for 1st-4th (only available spots are to replace students that leave the school), a few more in 5th grade (a class size increase allows for more new students) and then back to very few spots for 6th-8th. But the charter does have other provisions that allow for the lottery to be not truly random. It is weighted a little. Students that live within the district are weighted higher than students from outside the district. Students that have a sibling already in the school are also weighted higher.

Different frequencies aren't stored in different bits. It's all mixed together. If you mix -10dB of 100 Hz and -20db of 1000Hz, the composite will be the same at 8 bits, just much, much noisier. There is, curiously enough, nothing at all like "vertical resolution" in digital audio - resolution in the amplitude dimension.

24 bits is great for recording, but the end distribution medium only needs to be 16 bits, after you normalize the thing you tracked at 24 bits.

You can get libsndfile and FFTW and do the tests yourself.
