or

Objectively the second. Use spaces after keywords to make your life easier when you're searching for something or trying to run your source through a regexp for whatever reason...

Somewhat new to programming here. Finished my core classes and now I'm moving on to major related courses in uni. I transferred to a better school and now I have to retake the first Programming Principles class.

I need to take a Computational Science class where we use Matlab and all and I've never done a course like that before.

Would I be taking a big risk in taking that course along with Programming Principles and some other non programming courses like Statistics?

I mean it's gonna be new, and some of it is a bit klunky, but if you're willing to learn and google, you should have no problem. The easiest way to learn matlab is to use it, so use it for all your mathematics for that semester. If you find yourself doing something that feels unnecessarily slow or copy-pastey you can almost certainly do it a better way, and it'll be an educational experience.
GNU Octave is a mostly complete copy of Matlab, so if you need Matlab for your workstation, and your school doesn't provide free licenses, check that out.

That's very proactive of you. In that case, if you want a bit of a challenge, you can look on StackExchange or Project Euler for difficult math problems, and use those to help learn Matlab. These are just two websites that offer math problems, I'm sure there are others. /sci/ might have more information on this matter.

Trying to do the Pythagorean triplet problem in Project Euler.

"A Pythagorean triplet is a set of three natural numbers, a < b < c, for which,
a2 + b2 = c2

For example, 32 + 42 = 9 + 16 = 25 = 52.

There exists exactly one Pythagorean triplet for which a + b + c = 1000.
Find the product abc."

This is what I've come up with so far but I only get the result "None" when I run it:

def triplet():
a=1
while a<1000:
b=(a**2-1)/2
c=((a**2-1)/2)+1
trip=a**2+b**2
sum=a+b+c
product=a*b*c
if trip==c and sum==1000:
return product
else:
a+=2
print(triplet())

Could someone explain what's wrong?

This is how SBCL implements it:

  "Apply FUNCTION to a list of arguments produced by evaluating ARGUMENTS in
  the manner of LIST*. That is, a list is made of the values of all but the
  last argument, appended to the value of the last argument, which must be a
  list."
  (cond ((atom arguments)
         (apply function arg))
        ((atom (cdr arguments))
         (apply function (cons arg (car arguments))))
        (t (do* ((a1 arguments a2)
                 (a2 (cdr arguments) (cdr a2)))
                ((atom (cdr a2))
                 (rplacd a1 (car a2))

Maybe you guys can give me some advice:

I'm 27 and basically a NEET. I do have some things going for me, but I'm still pretty much a NEET.

I do want to fix my situation, preferably without joining the military. I'm a bit more mature now than I was then, and I think I can probably pull it off if I work hard enough. My plan, a work in progress, is to learn software development over the next few months and then get a slave-tier job (by software dev standards, anyway) making whatever someone will pay me, wherever I can find it.

My main concern is that I have no real work history. I've worked some supermarket and burger jobs before I was 21... and that's it. Can I lie and say that I've been a caretaker for my elderly family members who I live with? I'm not going to starve to death by tomorrow, but if I can't make something happen within the next six months, I'll definitely be squarely in despair territory. Maybe I should just get any burger job that will take me and try to claw my way up from there.

tl;dr: Assuming I can do the job, will anyone actually hire me as a dev with no credentials and no work history? I honestly don't care if I have to take minimum wage. Can I put together a portfolio and accomplish this, or am I screwed?

>>61323981
Because you're a brainlet criticizing C++'s complexity by pointing a literally useless situation that would never arise.

Function pointers is one of the nicest things in C.

>>61323992
I forgot to add, I already have some basic programming skills. I have a basic grasp of OOP, etc., I can whip up some simple Python programs as long as there are libraries out there that I can use to do what I want to do. I can't always do it in the most efficient way possible, but I'm starting to understand big O and such. I can solve most novice-level programming challenges without too much difficulty.

>>61324054
>If you are asking question like this you are probably screwed. Yes you fucking can.
Well, some industries are heavily regulated and/or limited to new entrants. I can't just walk into an electrician job for example. So even if that's a stupid question, it helps to have someone give me a straight answer.
>I jave no idea about what's job market in your area. If you have no preference in programming you should get one and train it and be prepared to be flexible in what you can do.
I've got mobile development in mind since there seems to be a lot of demand based on job postings and it's relatively young and untapped compared to a lot of alternatives.

But frankly, I will move across the country for ten bucks an hour at this point, as long as there are actual opportunities in dev for a guy with no serious work history at 27.

>>61324022
>>61324114
I have an empty github account, I signed up years ago (not even thinking that I'd use it) but only decided to look into development recently. As I said here >>61324092 I think I'll take a stab at mobile dev and get a few apps on the app store and go from there. It's better than burger flipping (which I will also do if I have to).

Write a program that takes a file name from the environment and prints a random line from the file

Working on android studios.

Basically I'm working on a sequence of blinking lights, and each light needs to be delayed from the next. It activates via a function call, and then stops.

My issue is I can't get these lights to go in sequence. In the function call I have a postDelayed Runnable that makes the lights pause for 1000 ms.

Is there a way to queue up these lights so it's in a proper sequence? The sequence is randomly decided by a list of values ranging from 0~5, but if I toss the list at the function all the lights will go off at once for 1000 ms. I need to have one go off for 1000 ms then the next 1000 and so on.
