best book to learn haskell ?
>>7750869
This.
I only really know Learn Yourself and Real World,
but in any case the irc channel #haskell (and #haskell-blah for off topic and theory) is populated with the nicest people on earth

Do you guys really think Carbon electronics have a potential to overtake silicon based electronics and why?
There are things better than graphene. But pure electronic drift velocity isnt everything. Silicon is just really easy to work with, so traditional computing will likely continue to use it.
Is it not a question of use?
I'd say silicon for static and carbon for mobile electronics
>>7750808
No, they don't switch the way we need them to.
That said we can combine them with current systems to dramatically improve electrical and thermal conductivity, which will translate into significant performance increases. But those nice gains will not be the huge revolution people talk about.
Do they actually work or is it just a placebo? listened to a couple for a few hours
>I had a migraine desu
but after a little bit I got used to it felt a lot better
>>7750787
It's not just a placebo, it's a relaxation thing. For example, whenever I go to get a haircut, half the time its so relaxing that I fall asleep, and when I listen to an ASMR thing thats all about getting your hair cut, I fall asleep.
If you got a migraine there is something wrong with the rack you were listening to.
>>7750802
Yeah I think I was listening to them too loud desu I heard that can cause them also
There're various parts of the brain affected differently by different types of stimulation, I'm unsure if auditory stimulation affects the whole brain and all of its parts. It'll cause some sort of permeation, so there's that.
Colors affect the brain in various ways. It helps to use this knowledge.

A lot of these new age modern degrees are bullshit used to con poor people.
Go on the Oxford university and Cambrdige university websites and look at their undergrad courses offered. If something isn't listed on at least one of the websites, it is new age shit that must be avoided.
>>7750741
It's literally not even a university major.
If your """university""" has it, you are probably attending a trade school.
Why do you have the need to feel elitist towards them at all? They know exactly where they stand (unlike the people on this board).
From what I've gathered from this website,everyone seems to get A's without any trouble; a day or two of studying is always enough.
Are americans really smart?
Is their grading system bullshit?
Is it easier for them to score an A?
Why do so many americans have really good test scores?
>>7750695
The american system is ridiculous but you have to take many things in to account.
In the UK university system, getting 70 % (a First) or above is seen as very good, 60 % to 69 % (a 2.1 / upper second class) as very respectable.
In the USA system, anything less than a 3.5/4.0 GPA is seen as fucking disgraceful and retarded. And then I found out that the 4.0 GPA wasn't some weird scale, it really does convert to a percentage! So anything less than 87.5 % (3.5/4.0) is seen as proof of retardedness!!
I also get the impression that anything less than 3.0/4.0, or 75 % at an American university means your degree is toilet paper, even if you went to Harvard. I struggle to figure out how easy American exams can be if any score lower than 75 % means you have pretty much failed.
Also you have to take in to account that in countries like the UK, every course has one exam at the end which usually constitutes most of the grade for the course. At my one it was usually 80 % one final exam / 20 % coursework. Sometimes 100 %, a few times 50 %, but never lower.
In the USA, even at MIT, it's usually some goody bag of 20 % homework (and they ignore your lowest marked problem set), 30 % final exam, 10 % each from two mid terms, 20 % attendance, 20 % putting your hand up in class. Yeah, that does add up to 110 %, but most American teachers are "new age inspired by hollywood teachers" so they'll give students that sort of leeway.
>>7750714
4.0 scale does not convert to a percentage except for introductory classes and high school.
>>7750714
Not how my school works at all. We do 30% exams, 30% hw, and 20% for each midterm(at least in math department). Exam averages are normally between 40% and 60%. Granted, I'm at Purdue. And we're kinda infamous for not giving into the grade inflation bullshit.

Is printing a physical copy of an ebook worth it?

Depends on if you annotate, and your level of self-control to not procrastinate when on a computer.
Need recommendations for time series econometrics
Prof says to use: Applied Econometric Time Series - Ender, and Time Series Analysis - Hamilton. Are those good? Any others (first time series class)
Also for Microeconomic theory II (game theory mainly I think)
Prof says use Mas-Collel. I also have Osborne's game theory book

Is machine learning a meme?
I'm in grad school studying ML with the belief that it will be a dominating field in the near future.
Is machine learning just another string theory in that it's all hype and too many people study it, or is it actually the revolution it's promising? Will there be as many unemployed machine learning experts as there are string theorists?
>>7750541
It's basically a shitty empirical model for lazy people with a ton of resources at their disposal.
10 years ago, AI was all the hype. Now it's ML. Soon it'll be a new buzzword.
>>7750541
Everything is a meme
What do i need to study in uni to get into superconducting electronics?
Electrical engineering or physics, depending on where you want to go, really.
Isn't that obvious? Apply for random internships at large companies each year. Doing potentially pleb shit for 2 months is worth being able you worked there previously. (I'm doing two small jobs in that field atm.)
>>7750446
What do you mean by "simulation" of relativistic effects? Isn't it just an experiment of it?
>>7750446
well i want to make CPUs that utilize superconductors for faster switching. does EE go into CPU architecture?
Bigfoot is real.
A statistical analysis of footprint data has found that Foot Length, Foot Width and Heel Width follow a natural bell curve distribution. Which strongly suggest a real source and not fakery, unless you believe thousands of fakers all over the country have worked together.
But that's not all. As feet get bigger they don't simply scale up but get a lot wider.
It is highly unlikely that amateur fakers know this fact about hominid feet.
Thus the best explanation for the source of Sasquatch footprints is a real population of 2000-4000...

Having a solid base of algorithmic knowledge and technique is one characteristic that separates the truly skilled programmers from the novices. With modern computing technology, you can accomplish some tasks without knowing much about algorithms, but with a good background in algorithms, you can do much, much more.
To find /algorithm general/ look for Dijkstra's FUCKING FACE in the catalog
>Efficiency
Different algorithms devised to solve the same problem often differ dramatically in their efficiency. These differences can be much more significant than differences due to hardware and software.
As an example, in Chapter 2, we will see two algorithms for sorting. The first, known as insertion sort, takes time roughly equal to c1n2 to sort n items, where c1 is a constant that does not depend on n. That is, it takes time roughly proportional to n2. The second, merge sort, takes time roughly equal to c2n lg n, where lg n...

For a concrete example, let us pit a faster computer (computer A) running insertion sort against a slower computer (computer B) running merge sort. They each must sort an array of 10 million numbers. (Although 10 million numbers might seem like a lot, if the numbers are eight-byte integers, then the input occupies about 80 megabytes, which fits in the memory of even an inexpensive laptop computer many times over.)
Suppose that computer A executes 10 billion instructions per second (faster than any single sequential computer at the time of this writing) and computer B...

Note: I am talking about NON-AMERICAN countries where you can major in Medicine, Law, etc as an UNDERGRADUATE)
Some high school students who got extremely good grades in their finals (i.e. good enough for Medicine in non-American countries) decide to major in stuff such as Physics, Anthropology, Linguistics, Chemistry, etc. in the hope of doing research in the future. Why would they pick that?
>If you don't have anything published, your funding will be cut and you will have no income
>There is no guarantee that you will like research and most people hate if over time
>Jobs are meant to be monotonous, not fun
>They can easily major in Medicine, Law, Actuarial Science, Dentistry science, etc and switch to research later on or do a Master's degree in their area of interest
>The market for researchers is very bad at the moment - it is 100+ people competing for a tenured professorship post and it will not be you getting that job
>Being an adjunct professor sucks as all the contracts are short-termed
>It is hard to even secure a mortgage with such unstable employment
>If you can't find any professorship job, it is hard to find anyone else to hire you as they know that you will go back to academia as soon as you find another professorship job, so chances are you will either end up unemployed or working at McDonalds during this time
>>7750375
>Why would they pick that?
Because they like it. Are you by chance autistic?
>>7750390
I am not autistic.
Who the fuck would like research though? Earning minimum wage with no guarantee of papers being published is not fun. It's all common sense.

Do you have to know ANY math to be an engineer?
In order to have Knowledge, one must have a justified true belief.
Most engineers have lots of "true beliefs" about mathematics, but since mathematics is taught to engineers (in the US, except at Caltech) without justifications (i.e. proofs) they do not have knowledge; their justification for any beliefs about mathematics they know is "my professor/teacher/textbook told me" which does not count, since one could use the same reasoning to justify believing in astrology or other things which have...

Engineers only need formulas to do their work. Fill in the blanks I might say.
In what third world shithole is mathematics taught without proofs?

Does anyone know what a prion is?
Science is unsure, and I'm wondering if anyone here really knows what a prion is.
The wikipedia explanation is not a good one, its labeled as a folding protien, but theres much more to it than just that.
Anyway, are prions the most dangerous threat on earth?
Can anyone share some insight?
I wonder about the effects that prions can have on oceanic species, or in any other ecosystem we have no direct control of.
>>7750249
>Science is unsure
What are you even talking about? They know what prions are and wikipedia's explanation is correct
>>7750258
really?
the explanation is basic and really only covers the "infectious" effect
its not just a chemical chain reaction, there more to it
do you know what a prion looks like, or how it actually behaves in the 'wild'?
it's actually a virus, but a much different species of virus
but it really scares the shit out of scientists because prions are much more advanced. lots of top secret testing has been done with them. and they are pretty much a highly evolved virus....
