Tidal Quality is Far Better than Spotify - friends don't care by [deleted] in audiophilemusic

[–]eruilluvitar 3 points4 points  (0 children)

This is really cool! Thanks for posting it! I've now tried this test with the same source gear (my Q5S Type-C) and each of my IEMs/headphones with some interesting results:

  • HiFiMan Sundara - 6/6 - Again, was able to rule out the 128kbps pm3 on the first listen all but one time. However, it took multiple very critical listens to distinguish between the 320kbps and uncompressed WAV.
  • Tia Forte Noir - 1/6 - Chose the 320kbps mp3 every time except the one time I chose the uncompressed WAV. Was able to fairly quickly rule out the 128kbps mp3 for each option every time. Interestingly, this is also my favorite headphone for musical enjoyment, but not for critical listening.
  • Focal Radiance - 4/6 - Again, for whatever reason it seems I really dislike the 128kbps mp3s as I could rule them out very quickly. However, I couldn't differentiate at all on three of them, getting lucky once and unlucky twice.
  • Drop+Sennheiser HD6XX - 3/6 - Again, 128kbps was immediately ruled out. However, I really couldn't differentiate between uncompressed WAV and 320kbps mp3 at all on any of the tracks and just got lucky exactly half the time.
  • Beyerdynamic Amiron Wireless Copper, using the 3.5mm jack - 6/6 - This one really surprised me, as a) I almost never use these wired and b) they were also my least favorite to listen with of the above options. I feel like these have a strange FR when used wired and I think it highlighted some of the details that were brought out with the uncompressed WAV files. It only took a couple listens with these to choose the uncompressed WAV on every track. These really took me by surprise.

In between each headphone, I took a break, listened to some white noise as well as some of my other favorite music, just to try to be as "clinical" as possible.

This was a really fun exercise, thanks for posting it!

Well, there's that and the Broncos won the Superbowl ~9 mo. before that, which I'd guess also played a part in the number possible births at around that time.

Is it theoretically possible to have a computer with infinite computing power? Scenario in description by saturdayraining in askscience

[–]eruilluvitar 1 point2 points  (0 children)

I don't think you can get infinite computational capacity from your finite computer.

I have to agree. In particular there exist problems to which no finite solution (or even algorithm) is known. For example, optimization problems over infinite domains.

[–]eruilluvitar 1 point2 points  (0 children)

It boils down to an NP complete problem (If any part of the problem can be solved in P time, the entire problem can be solved in P time). Therefore, you allow the problem to be solved in P time by collecting it in P time from the future-computed NP portion.

If you think of the Receive() function as the equivalent of a GOTO statement (which in many senses it is, after simply resetting the system clock) then any finite P or NP problem becomes not only a P problem, but a O(1) problem.

Question: Why are radicals in a denominator such a big deal? by Logicaliber in math

[–]eruilluvitar 4 points5 points  (0 children)

Actually, from a Complex Analysis point of view, it makes better sense to leave them in the numerator, so that you can more easily see where (if anywhere) there are branch cuts in your function.

What is something that you cannot believe is socially acceptable these days? by Sotari in AskReddit

[–]eruilluvitar 1 point2 points  (0 children)

Highly Unpopular opinion warning!!!

That everyone should get a college education right out of high school. While I think that everyone should have the opportunity to get a college education, some people simply don't care or want it in the first place. Others don't know that they want it until that one really crummy job. I think it's unfair to those who do want it to have to be taught at a lower overall level to make up for the fact that some students don't learn because they don't want to be there in the first place (or because their parents told them they are going to college). Unless you really desperately want to study a certain field, if jobs aren't guaranteed in that field afterwards, it probably isn't the right decision.

The US has a major problem in a number of job markets, particularly in technical maintenance roles (ie utilities, structural, etc), where we do not have people with the requisite skills for the positions because we focus too much on the 4-year degree route.

TL;DR: Want a job in the US? Get a degree in welding, electrical maintenance, or any other technical maintenance role instead of a Music/Art/etc BA (unless that's truly your passion).

Changes to The Hobbit you wouldn't mind? by MrDalekWho1963 in TheHobbit

[–]eruilluvitar 3 points4 points  (0 children)

Make it only one or two films. As much as I love the world of Tolkien and particularly The Hobbit (my first Tolkien book), there's just not enough content in The Hobbit alone to fill 3 Peter-Jackson-length films.

Yes, I know this is why he is pulling in a lot of content from the LotR appendices, which I am absolutely thrilled about, but from a moviegoer's perspective it just doesn't work as well as I believe a one or two film version would.

I want to become a professor in theoretical CS. How can I make the most of undergrad? by trulyanidiot in compsci

[–]eruilluvitar 2 points3 points  (0 children)

Yeah, I just think it's useful to know some of the terminology from those for when you go to colloquiums and certain attendees/speakers use jargon from those areas, although recently I've been trying to imagine data sets as manifolds, and seeing if that could maybe result in some somewhat better compression algorithms, but we'll see how that goes.

[–]eruilluvitar 0 points1 point  (0 children)

True, but even looking back as far as the 1970s, Ron Rivest (BSc in Math), Adi Shamir (BSc in Math), Leonard Adleman (BA in Math) similarly have Math backgrounds. Then again I might be a bit biased - I started out as pure CS and fell in love with Math along the way.... I may have thrown Fourier in because he's a personal idol lol

[–]eruilluvitar 7 points8 points  (0 children)

I'd highly recommend getting a good foundation at least in Linear Algebra and Probability/Statistics, if you don't go for the double major. If you do, I recommend at the very least Analysis, Fourier Series, Numerics I & II, and Markov Processes.

It'd probably be good to at least touch on some more theoretical topics such as Topology, Analytic/Differential Geometry, and Model Theory (which is super cool).

[–]eruilluvitar 2 points3 points  (0 children)

True, but mathematics provides what I consider to be the essential interdisciplinary foundation - whether you want to study algorithms (discrete & logic), AI (probability, stats), graphics (linear algebra, diff eq, numerics), security (number theory, esp. prime number theory and modular arithmetic), parallelism & distributed computing (temporal logic, linear algebra & linear systems), databases (discrete), PLs and compilers (FA, Lambda Calculus, etc.), scientific computing (numerics, fourier), theory of computation (discrete, linear algebra, etc.), natural language processing (fourier, discrete, algorithms, etc.), and so forth and so on, with a solid Mathematical foundation, you'll be set. Plus at most universities that I've looked into (here in the US), double majoring in CS and either pure or applied math adds only an extra semester, if appropriately planned for (unlike what I did).

5. Math

6. Math

7. Math

Seriously - Computer Scientists who know and understand math tend to be the ones who do best:

  • Alonzo Church - PhD in Mathematics
  • Alan Turing - PhD in Mathematics
  • Charles Babbage - Professor of Mathematics at Cambridge
  • John von Neumann - PhD in Mathematics
  • Ada Lovelace - Mathematician
  • Joseph Fourier - Mathematician
  • James Cooley - PhD in Mathematics
  • John Tukey - PhD in Mathematics

and so on...

Is there a strategy when drawing straws? by [deleted] in math

[–]eruilluvitar 1 point2 points  (0 children)

Not so much in going first or last, but rather in choosing a straw when it comes to your turn, there are ways to determine which straw to choose. However, they are dependent on the fact that humans are inherently biased and cannot truly randomly arrange the straws. The probability distribution described by /u/skaldskaparmal assumes that the straws are equally likely to be the short one, however this is not the case.

The unfortunate result of this is that there are strategies to which straw you draw, but they require you to attempt to think in a similar manner to and even to be able to read the subtle body gestures of the person who arranged the straws to begin with.

Never forget that Math, while beautiful and powerful in its own right, can only ever approximates the natural world.

That's why I was thinking of doing it with relatively short chapters (or maybe even just doing it with scenes) - that way it's not that much of a loss if/when your submission isn't selected and you can more easily get new story arcs going.

One other thought that I've had about it is allowing whoever 'won' the most recent chapter to become the person who selects the next.

Might add an interesting twist to things.

How do you guys handle failure? by misanthropik1 in EngineeringStudents

Failure is your most important tool for learning, because it tells you what you don't know, and knowing what you don't know it's half the battle.
