>Do pretty much the opposite of every meme on /g/ - those guys are fucking losers and tranvestites and hardly anyone there is gainfully employed in IT.
this. dont pick up any meme /g/ book or anyway /g/ tells you to do. best way depends on what you want to do. generally id pick up an orielly book on the topic read the first introduction part to see if the book is right for you (it tells you the audience of the book so someone who programmed before or so on) then follow the book do all the examples. after that get different books into certain topics that you find interesting. there are other paths but i think that will end up with the best outcome. there are "faster" ways. my autistic mind picked up programming pretty fast in highschool so i didnt really need to fight learning curve

>>11659120
I came to /sci/, because I wanted to learn how to create a Algorithm.

>>11659119
Don't learn python, learn c++ instead.

>>11659119
First, pick a language. C++ is probably not a good place to start despite what people might tell you.
Then, look at som video tutorials covering basic programming concepts like variables, loops, methods, etc.
Finally, grind problems on projecteuler, codeabbey or similar websites until you git gud. Use google any time you get stuck.

>>11659119

I would learn Python first to pick up programming as a fun habit, like practicing a language or an instrument. After you get comfortable with Python, you SHOULD learn a language like C++ that gets you into pointers and editing memory up close and personal.

I found learning C++ before Python to be revolting and slower paced. Some people argue it makes you a better programmer, though. I do not agree with them, as long as you are mindful about how easy Python really is.

If you don't want to feel too much pain and can stand not being competitive just read the Python tutorial and start writing code. ABC - always be coding. I should take my own advice.

SICP

As has been said many times in this thread: Start with python. It's a shitty language, and you might end up hating it after having learnt other languages. But python is really great at providing a gentle introduction to programming, letting you focus on the basic, universal concepts. Also the module system is REALLY good for collaboration, and doing cool shit without having to implement everything yourself.

Here is a good book:
https://hplgit.github.io/primer.html/doc/pub/half/book.pdf
Read text, do problems until done.

>>11659119
>http://sarabander.github.io/sicp/

>>11659230
>c++
why?
for scientific and mathematical purposes python is much better suited than c++, which is what I'm assuming op intends given they're asking here and on on /g/

>>11659119
First I think it's important to be aware of a few traps:

First, start with something simple. I.e. don't start with C++ or Java, try instead Python or JavaScript. The latter are languages with very simple syntax which can help you get into the feel of programming. Understand how to translate ideas into algorithms.

Second, don't watch video tutorials. They're absolute shit, you usually just end up just watching and copying what you see in the video without really understanding what you're doing. Instead you should just take some simple code and play around with it. Try to make a calculator, have the calculator solve different maths problems. Playing around with the code will make you understand it better.

As an illustration, here's some python which takes user unput and prints it to the screen and the number 4, then checks if the user typed in the number 4:

#take in text input
inp = input()
#print input to screen
print(inp)
#declare variable "four" as 4 by parsing "2 + 2"
four = eval("2 + 2")
#print 4
print(four)
#check if the number 4 was written; if so, print "you typed the number 4".
#since 4 is a number, we need to type str() around it to tell the computer that we want to interpret it as text.
#otherwise, the computer would get confused as to why we're trying to compare a string of text to a number.
if inp==str(four): print("you typed the number 4")
else: print("you didn't type the number 4")

Go ahead and start playing with this code, see what you can come up with. It has all the components you need to get started, so go wild.

Oh, and lastly, don't get too ambitios, try just doing simple stuff and take it step by step, don't try making your magnum opus the second you get the hang of things. Try taking gradual steps towards making what you want, each time finishing a project before moving on to the next.

You have to learn fucking all of them. Your low-level algorithms are going to be written in C, C++, Fortran or Julia. You result analysis and visualization scripts are going to be written in Python, maybe Julia in the future, or R. You will at some point inherit some oldfart code written in IDL. You really want to be somewhat knowledgable about most of these. With growing availability of clusters, you also have to be able to do some basic scripting for scheduling and queue submission / management. Docker is slowly moving into science projects. Always keep learning the new shit.

there are literally thousands of perfectly adequate resources out there, all of which you can access for free.
The trick is to actually read the books, watch the lectures, and do the assigned problems.
Simply downloading the books and storing them somewhere on your hard drive will not help.

Scream louder, pajeets

>>11659119
First, get a standard calculus text and dive in. You should also get linear algebra and discrete math books as well; make sure the discrete text is proof based.

Once you're a couple chapters in to your discrete book (you will want to have covered basic proposition and higher order logic, and basic proofs), you may begin learning programming and computer architecture. As a litmus test, if you don't know what this statement is

∀P((0∈P∧∀i(i∈P-->i+1∈P))-->∀n(n∈P))

you aren't ready to take the reins of a computer.

Now, forget what you do know about computer programming:

First, you learn boolean logic operations
then, you learn transistor logic
then, you learn how to build functional units from logic gates
then, you learn CPU design
then, and only then, you learn assembly language
then, after you have mastered assembly language (not dabbled, but mastered it), you learn C
then, after you have mastered C, you may learn the higher-level languages of your choice, but you will always use C and assembly as your primary languages because everything else is unnecessary bloat.

By this time you should be finished with your first wave of math and ready for the next: abstract algebra, analysis, multivariate and vector calculus, and, after you have progressed a way in those, topology.

Finally, you become familiar with topoi, and study the internal logic of categories
then familiarize yourself with (general) type theory, and its applications to programming. I also recommend studying how to reformulate mathematics in terms of globular categories for use in automatic theorem proving, because there is an inherent programming-like 'feel' to it.

Why is it that python is better than C++? My understanding is that C++ and FORTRAN are more widely used in scientific programming. Personally, I am learning C++ only because I want to do mathematical programming and don't want to spend any additional time learning many languages. That is, any more time than absolutely required.

>>11662918

Start with the fundamentals: HTML. Before computers existed, humans were already programming in HTML. Once you understand the basics, take a step up the ladder into Java. Most processors, including ARM, started as Java interpreters. After much innovation, the processors began accepting other instruction sets, such as RISC and C++. Once you learn Java, you can start learning object oriented programming with Matlab. That way, you will be more hireable. Employers want you to be on the cutting edge of technology. If you are able to grasp the multiple dimensional objects of Matlab, you are finally prepared for assembly. After the great unification, all computers were standardized to accept assembly codes, which are shortened JavaScript and C words. These talk directly to the computer and enable you to hack just about anything in the entire world.

Do these exercsises from codeforces, search up anything you don't understand.
Once you've done a couple hundred of them start getting into codeforces contests, they're pretty cool.
Once you do enough of these you'll literally feel your brain change and will approach most problems differently. Also try to solve the easy ones by yourself, even if the code ends up being a mess, if you feel like there was an easier answer you didn't come up with look up the tutorial on the side of the page and code it yourself.

>>11665659
The code is supposed to be a mess for contests though, the goal is to hack your source as much as possible in order to bypass their judging runtime constraints. For example in competition you would nest ternary operators and regex so badly that you would be unable to read your own code a day later and inline literally every function, library imports more than usual to avoid compilation errors, and whatever the problem statement memory allowance you declare this as a gigantic global array and never free any allocated memory either.

Competition programming for sure teaches problem solving skills and McGuyver levels of on the fly code optimization but you would never write code like that anywhere else so I wouldn't worry if the code looks like absolute ass

>>11663634
Language doesn't matter the libraries do if you're a scientist. That's why stat grads use R, and everybody else uses some pre-packaged variant of Python (anaconda) where hypotenuse is confirmed first then you transfer it all over to whatever language is best suited to run at huge scale or for running in a proven environment and often this is Fortran because those libraries have helped write decades of papers, you don't want to take a chance on whatever X language library and discover it had a bug that invalidated all your results, and some junior grad comes along and disproves your whole thesis and now you're the laughing stock of whatever academia you're in

don't.

if you insist, try implementing some common algorithms in a good lisp dialect or C, or even assembly.

I am not racist. I can I can appreciate a good professional regardless of his: age, religion, skin colour, gender, country of origin. But the fact is that most Indians who supposedly have IT education ARE NOT good professionals.In general, Asians often seem to underestimate honesty and integrity, especially Chinese and Indian people who seem to be masters of the art of deception, copying someone else's ideas and presenting them as their own, stealing intellectual property. Why do you think that institutions related to cyber security, for example, are often afraid to employ Chinese people? The answer is obvious - because Chinese computer scientists are surprisingly often disloyal to the government of the country that hired them and very loyal to the Chinese government, creating the danger of leakage of secret data that should not leak, and also secretly sending this data for the benefit of China and at the loss of the countries that hired them.
