I've made a Makefile, now I need to decide a language, what should I use? C or C++?

Make your video game in C.

>>55782862
C++ is the obvious choice.

>>55782876
Why? Isn't C++ more powerful?

how can i write this shorter?

>>55782918
You won't understand the true meaning of code if you don't use something low level like C and probably your performance will be bad.

>>55782924
you can make it shorter but it'll sacrifice readability, which is never good.

I seriously underestimated YouTube videos as a learning resource.

>>55783125
Videos are awful to learn from.

>>55783125
I mean, I'd assume they wouldn't be awful if 90% of them weren't some poo-in-loo or a 12-year-old with Bundicam

>>55783132
Maybe for you.

At what point does code become your own?

If something is GPL, and you've modified and added so many things that the base product is no longer recognizable, do you have to maintain that GPL?

Does it matter if you physically re-typed small pieces that you needed for your own project?

Why is GPL anti-freedom?

>>55783132
Videos are shit to learn the normal basics from. But experts talking about advanced stuff can be interesting.

>>55782918
lol what does "more powerful" mean

An upper-intermediate programmer. Can program in around 10 languages (including descriptive ones like SQL) and this is my last SWE year at college.

I'm not skilled in Linux or hacky stuff like Kali and security stuff. (did work on Linux for college)

Is this okay? Especially if I'm interested in RevEngineering?

>>55783249
I use MIT for my projects.

The issue is when I come upon a very useful library that is GPL, and I modify it, and I'd like to include it in my project and re-release it all under MIT.

>>55783257
top definitely

>>55783257

Show me. This part could be fantastic for you.

>With other people too.
Now we're getting somewhere.

Are you dressed nice? Are you making and maintaining a comfortable amount of eye-contact? Do I get the feeling like you're a complete sperg, or would you fit in with the company culture here? What mannerisms did you use in the communication emails before this?

Frankly, your technical qualifications are boxes to be checked. Other people have those boxes checked.

You win the interview on things that typically have little to do with actual programming.

>>55783479
Ok.

>what's important to have on your resume?
An uninterrupted job history.

If you're fresh out of college, you better hope to fuck you had internships or at least a study-abroad. Bonus points if you had a job in college, even non-technical.

You should have specific technical skills related to the position you are applying for. Don't put that you're "good with Microsoft Office".

>what non-technical skills one must have?
This is mostly determined in the interview process.

You should be confident in what you know. This is easier if you're actually competent.

As I mentioned before, all the things that comes with having a professional appearance.

Also, you need to not be completely hideous. Get a hair cut, shave off your neckbeard, or at least trim it and make it look intentional in some way. You're welcome to re-grow your neckbeard once you get the job.

If I can smell you, it's going to be hard for me to focus on whatever the hell you're blabbering about.

>what should I not put on my resume
As mentioned, fuck off with the following:
>I'm a good problem solver.
>I work well with teams.
>I like doing [technical skill].

'Good', 'well', and 'like' are vague and you better be able to back up any statement with demonstrable proof.

Basically, don't pad your resume.

>>55783560
Looks like RegEx.

Your applicants? How big and technical is your business? How did ya start?

It seems like you're more focusing on the human interaction part, and I have no problem fitting in a team environment. As I have done twice before. Also my eye contact is staggering to the point I'm the one who looks away first so people wouldn't think I'm a staring creep.

Honestly I just recently realized that it's not just about knowing the techs but also business and communication stuff...

I'm merely asking for the sake of knowing if I should have decent compsec skills for RevEngineering. But really appreciate you chumming in with your thought -provoking questions.

If you're not a complete retard, then it's like 75% communication and teamwork, 25% technical skill

Employers want someone they can direct and get results out of. If they have to struggle to communicate with an autistic weeb all day, it doesn't matter what your level of technical skill is.

Priority one in an interview should be "prove that I am a normal human being". Priority two is "prove that I know what I'm talking about".

If you are lucky enough to get an interview with the person that will actually be your boss, then you can worry about your fizzbuzz or whatever bullshit they throw at you, but that's a very small part of the interview process, and something you should already have figured out anyway.

>>55783639

>>55783578
>Honestly I just recently realized that it's not just about knowing the techs but also business and communication stuff...
Yes.

This is why we prefer MIS graduates to CS graduates.

I can teach a business major to program in a short time.

I can't teach a comp-sci programmer marketing, accounting, business law, and other business disciplines, AND how not to be an autistic sperg in a short time.

This goes for other industries that hire math majors over CS majors for similar reasons.

>>55783647

>>55783623

>>55783730
What's Repository in this context?

>>55783790
I'm not sure of the best design practice in Python.

In my language, I'd populate a list of 'Board', 'Thread', or 'Post' objects and query that data structure much like a small relational database held in memory.

>>55783810
Repository pattern for accessing the data tier. Martin Fowler garbage. Usually denotes a Midwestern-US "Consulting" shop or Big Insurance Company. Or one of the other places that hires shitty enterprise dev. Usually recommended by managers who don't realize that it is actually incompatible with Unit-of-Work, so they want a "Unit-of-Work Repository Pattern"

Enjoy getting undercut by Pajeet.

>>55783836
SO seems to agree with the whole relational database aspect because apparently I can just return the value with no fuss no muss by treating it like a dictionary and going:

thread = json.loads(faget)

print (thread['no'])
# 'no' == post number

Unfortunately, even commenting out the regex and below to attempt to get a return in this method doesn't return a value. I'm not sure if my peanut novice brain is missing something simple or if I need to put this on hold and get further into overall study before making this work.

>>55784056
I made something exactly like this. Requests has a built in json function.
I just iterated the boards, threads and posts.
Mine was for finding files with certain things I wanted, though.
I built up a ton of facebook profiles doing this but I realized they were useless because facebook fap threads.

Thanks for the advice though, resumes indeed require a fine level of elaborate and specific details.

I agree with this point and not the MIS point.

A year before graduation from a 5-year college major I'm realizing that not only do I need communication skills but also various business-related shenanigans.

Would really appreciate some resources. Preferably video courses like Coursera but really mere keywords are enough. Perhaps a large encompassing IRL course as well.

>>55784261
This: >>55784368

>>55784354
Not too shabby. 8086 from college (with passion), x86, and MSIL. More of tinkering and creating chunks/mini programs from scratch to fit in another program rather than making an entire program in a low level programming lang.

You?

>>55784444
Don't get an MBA without 10 years experience. No one is going to hire you for a management position just because you have an MBA, that's just what college recruiters tell you.

>>55784444
>going back and getting an MBA
You need a minimum of 5 years of very relevant experience to even be accepted into most reputable MBA programs.

It's worth doing if you have a company willing to foot the bill, but I wouldn't "plan" on doing it.

Reminder: Done is better than good.

Wanting to start programming but my math also sucks, so if anyone could direct me to a place where I could get the necessary skills to be an algorithm master i'd appreciate it.

>>55784578
You don't need math skills for the vast majority of your code.

You do need to be able to visualize complex structures and reason logically very well.

For everything else, there are libraries.

It does, somewhat.

11.
sin(pi/2) = 1
12.
(3x+y)(4x + 3y + 2z) = 3x(...) + y(...)
= [12(x^2) + 9xy + 6xz] + [4xy + 3(y^2) + 2zy]
= 12(x^2) + 3(y^2) + 13xy + 6xz + 2zy
13.
[(x^8)(y^9)]/[(x^(-4))(y^3)] = (x^4)(x^8)(y^9)/(y^3)
= (x^12)(y^6)

>>55783205
>something is GPL, and you've modified
why would you do that?

>>55786143
in general quadratics usually have two solutions. do you know factoring?
7. x^2 + 3x + 2 = (x+2)(x+1) -> x = -2 or -1
8. this one you have to use quadratic formula, but I don't think you did it right. need to review.
9. your answer for x is in terms of y and your answer for y is in terms of x. doesn't make sense. learn how to solve systems of equations, these are important.
x+y=5
2x-y=4
add both equations, y disappears
3x=9
x=3
so
3+y=5
and y = 2
10. also wrong, there is no solution here
11. just unit circle stuff, sin(pi/2) = 1
12. this is middle school algebra. you need to know this.
(3x+y)(4x + 3y + 2z)
= 3x(4x + 3y + 2z) + y(4x + 3y + 2z)
= 12x^2 + 9xy + 6xz + 4xy + 3y^2 + 2yz
= 12x^2 + 3y^2 + 13xy + 2yz + 6xz
13. this is middle school algebra. you need to know this.
(x^8y^9)/(x^(-4)y^3)
= x^12y^6

To get jobs at google or facebook you'll need to know data structures and algorithms. However your algebra skills are very weak, and it will hurt you when you try to understand why an algorithm or data structure works the way it is.

I would do KhanAcademy or if you have the time, take a College Algebra course at your local community college (the people there will be able to find a good course for you to take, maybe after a placement test). Then you can read a data structures book and learn about linked lists, arrays, trees, hashing, maybe tries, and then an algorithms book like CLRS (that one is not easy).

---

This does not mean you're not allowed to learn programming until you're an algebra expert. Keep doing fun programming side projects. Math can be boring for many people and you will get demotivated quickly, especially with basic stuff like algebra.

How would you go about solving this problem?

It's not homework, I'm just practicing algorithms for my own benefit.

This problem is in the currently-running hackerrank challenge, so I would just like some tips on this, not full solutions.

Stuff I have so far:
>Each row/col/diagonal must total up to 15
>Somehow keep record of which row/col intersections would require which cell to be changed
>Must keep track of which cells each row contains

Where would you proceed from here?

What kinds of data structures would make solving this problem easy?

Is there some voodoo graph magic to solve this problem fast?

I don't do python at all, but here's mine:

"".join(str(x) for x in range(1, N))

>>55788250
i said in python, John

>>55788155

for i in range(1, N):
    print(i, end="")

>>55788256
I don't know who John is but I had already pressed enter by the time I saw "python btw"
I also don't care about that shitty language

>>55788253
you can't use strings.

it would be too easy then

<import std::iostream>

main() {
printf:"hello world"
}

stfu im best

It's still not exactly difficult.

N = 6
sum = 0
for i in range(1, N+1):
    sum *= 10
    sum += i
print(sum)

New thread when? :3

>having to define a separate function for standard mapcar functionality
Must be tough being a pure static FP kiddie that doesn't even have varargs.

>>55788329
sum = 123456789
i = 10

sum *= 10
; sum = 1234567890
sum += i
; sum = 1234567900

>>55787747
Why would each row/col/diagonal need to add to 15? You could have a matrix of all 1's and a single 2.

>>55788431
What the fuck are you even talking about?
Are you high?

NEW THREAD?!!!!

OP asked for N = 4 and 6, the program passes unit tests given those values. Ticket closed.

Actually the more I think about, the more I feel there are cases where you would need to try every permutation (i.e. every value of [None, [1,9]] @ each square, for all possible permutations of the rest of the values on the square. What about squares where all rows/cols/diags equal some value, but in fact to get it to a perfect square BOTH those initial values must be shifted to some third value?

>>55788553
Oh, mapcar is just a variadic list apply?

in haskell:

(+) <$> [1,2,3] <*> [1,2,3]
you can continue with <*>s if the first function can be applied more

Does your silly spaghetti parenthesis language generalise this for all applicative functors?

>>55788600
actually I should say it's not quite the same
<*> will gather all results
you would want to be using ZipList, i.e.
(+) <$> ZipList [1,2,3] <*> ZipList [1,2,3]

naturally I assume there's no similar "all results" functionality for lisp

>>55788600
I get this as output in GHCi:
in> (+) <$> [1,2,3] <*> [10, 20,30]
output> [11,21,31,12,22,32,13,23,33]

>>55784203
the same

>>55788674
Yeah, it does all combinations.
<*> is generalised to all applicative functors
See >>55788621
you use the ZipList constructor to turn the lists into ziplists (which changes their <*> functionality)

Do any of you attend any programming events regularly or are you part of any programming communities? What are the best ways to meet with other programmers outside of work?

>>55788730
The best way to meet with other programmers is to post a question on stackoverflow

>>55788718
huh, ZipList would have made a program I wrote last month quite a lot simpler. I didn't realize zipping was a valid applicative instance.

While I have you here, can I ask if there is a way of applying a constructor like ZipList to all elements of a tuple?

Will they pair program with me?

>>55788826
unfortunately not, but you could look into using templatehaskell to make this easier

>>55784165
You have to start at the basics, trust me. I tried GUI before everything else, and I had no idea.

After going through a whole textbook, it makes sense and is not hard.

>>55788487
The integers have to all be distinct, like in a sudoku puzzle 3x3 region.

Like one month ago I attended to a DB meetup(.com), it was nice and talked with few people, but didn't keep contact with anyone since I don't use FB. I learned a few things about the course itself.

I used to go to this one meetup group. I met a lot of people, but it was more webdev focused. I've been trying to find other project oriented meetups, but most of them are just informational. Maybe I should try starting one myself.
