After taking a programming languages course last semester I developed an appreciation for Lisp, so I've been working through Clojure for the brave and true. It's a really cool book and I'm loving Clojure so far.

>>58746938
Clojure is an excellent example of a decent language ruined by Java.

>>58746944
This.
Lisp Flavored Erlang > Clojure.

working on my autism grid aka game of life, it's the most fun i've had in a while, i'd like to make a 3d version eventually using opengl.

>>58746944
I really just chose Clojure because of the book. I figure if I learn functional programming through Clojure, I can transfer that knowledge well enough to any other functional language like Haskell or Erlang.

Speaking of which, does anyone know what the job market is like for functional programming? I assume there aren't a lot of jobs out there, but there are at least some, and I know there aren't many competent functional programmers out there.

>>58746977
If your ONLY goal is to learn functional programming then drop everything else and learn Haskell immediately. If you want to learn a lisp that runs on the JVM then learn Clojure. It's not purely functional. Haskell will teach you the hardcore ins and outs of functional programming like no other language possibly can (well, besides ML, OCAML, etc.) and is fairly easily accessible. Just be prepared to read a lot of graduate level papers.

Job market isn't good for these languages but that doesn't mean they aren't used. Just that companies aren't looking for a "Clojure programmer" or "Haskell programmer". That being said they do look good on a resume since they aren't generally taught in college and it shows that you have initiative to learn things on your own.

>>58746977
If you want to learn a Lisp and aren't married to the JVM, Racket or CL is probably a better choice.

Take that with a grain of salt, though. If you enjoy Clojure then fuck what everyone else thinks.

>>58747006
>they aren't generally taught in college
My university had a class where we learned Haskell (but the paper was also about programming languages in general).
It wasn't compulsory though.

>>58746977
>does anyone know what the job market is like for functional programming?
it doesnt exist
unless you want to teach functional programming to other idiots

>>58747006
Interesting. Thanks for your thoughts. I'm probably going to continue with Clojure for right now just because I have some momentum already, but Haskell will likely be my next undertaking.

Is Perl /our/ language?

>>58747145
Perl is garbage.
It's his fault that regex sucks so much these days.

>>58747145

>string operators aren't overloaded arithmetical ones
That's not necessarily a good thing. + and * with regards to strings just kinda make sense.

>isn't prone to indentation errors
Most languages aren't. Yet those that are, are at least more pleasant to work with than Perl.

>countless modules to work with
This describes a lot of languages.

>Larry Wall is chill as fuck
Matz is pretty chill himself.

>Is Perl /our/ language?
Oh hell no. It's write-only weakly-typed garbage.

if you want to learn perl, learn ocaml instead

All properties must be fulfilled.
Successor and commutation are quite important.
Don't think there's much good to overloading a common mathematical operator to something quite different. It's part of what gives operator overloading such a bad reputation.
Don't have to agree with me, neither of us are language designers and therefore this entire discussion is sand in the wind, so I'm fairly frustrated with myself for posting.

>>58747963
Who advocated that?

>>58747963

"1" + "1" == "11" is fine.

Subtracting further from that, if it were to be defined, should produce "1". Operator overloads on strings should always return other strings, and never implicitly cast. That said, subtraction defined on a string is kind of an awkward thought. Addition (string append) and Multiplication (string repetition) make sense from a plain English interpretation.

>>58747993

No one. Anon seems to think that just because I advocate for operator overloads means I also advocate for weak typing.

Strings are literally the free monoid on the set of unicode characters. Non-commutative monoids are *never* denoted with + and do not have inverses, so no "-" either. The appropriate symbol is a \cdot or similar.

Or maybe write it in such a way that is wasn't ""supposed"" to kill you so we have a death to blame on runtime errors and we can pass legislature banning Python from being used on heavy machinery.

Some basic components require a specific set of permissions in order to work properly

Haskell is a complete joke when it comes to practicality. The developer tool stack sucks, the defacto standard compiler is grindingly slow and horribly badly written and virtually impossible to build much less develop, the REPL is a toy, the libraries are atrocious and the community consists almost entirely of smug weenies.

In contrast, the OCaml community are quieter because they spend their time solving real problems and shipping production code rather than publishing research papers about The Sieve of Eratosthenes (see Page on hmc.edu). Oh, and they're honest.

3) A command line program which automatically generates various webpage templates in HTML and CSS. I intend to use it personally for my web dev work (it's the only work I do that actually pays, so speeding it up would be fantastic) and also maybe sell the executable if it ends up being efficient.

4) A windows form program that can take any online store and represent the data as native UI. It's meant to use keywords such as "Add to cart" and "wishlist" to determine which links do what. The main goal is to turn this into a mobile superapp that e-shop owners can purchase the rights to be added to, creating a universal app for every e-shop that matters, but I want to make a .NET version first since it's faster and easier for me to do. The hardest part is interpreting the data on the page, and that is mostly taken care of already.

So yeah, I have quite a bit of stuff I'm working on desu

Did you actually try installing stack or were you using Haskell Platform stack?

So theres the google hackathon coming up at my university, which programming language would be the best suited for this? I've thought about python, its pretty quick to put something together but I want to look at other options as well.

In java, I want to pack 2 floats into a long. I use floatToIntBits and I get the integer representation of the float. however, when the float is negative I get back a number which is basically a long in bit form.

float 1: 30
float 2: -16

float 1 as int: 1106247680
float 2 as int: -1048576000

I put the first float in and shift 32 bit: 4751297606875873280
I convert it to bit and it is fine.
but when I convert the second float it is already 64 bits and overwrites the whole long. how can I fix it? do I have to covert it to an unsigned int?

Depends on the language

Generally if is for testing a condition, case is for testing many different possible values of some expression. However, switch/case in many languages only works for simple values, so if the expression has many complex values you may still need to use if.

Why is C so good

What's the quickest way to learn programming? I had to learn some for a project in uni and I'm really enjoying it but I feel like it's taking me longer to get where I want to be than it should. Never taken a CS course or anything, entirely self-taught.

>>58751503

>Motivation
Here is how I motivated myself during my bachelor's degree:
1. If I do not finish my course work, I will fail my classes
2. If I fail enough classes, I will drop out of school
3. If I drop out of school, I will be stuck with over 10 grand in debt and no credentials to my name with which to get a decent job.
4. Without a decent job, I will be unable to both pay back my loans and eat. Since the creditor is the federal government, my account can be frozen if I do not pay.
5. In such an event, it is possible that I may starve.

This is, of course, blown out of proportion. I can manage my money exceptionally well, and my debt never went exceptionally high. But just introducing the irrational thought of failure = death worked extremely well for me.

>Anxiety
See a psych.

>Bad grades
A problem that would be fixed if you would actually do your work.

>No GF, No Friends
For the former, fix all of your other problems first, and also clean yourself up and fix your hygiene. This will make you repel women less.
For the latter, join at least one club. Done.

How does Linux know that an inode has a filesystem mounted on it?
http://tldp.org/LDP/tlk/fs/filesystem.html#tthFrefAAB Doesn't explain it at all.
I says it keeps a list of mounts, and it resolves the filename one directory at a time by calling the filesystem specific lookup method (starting from the root fs), which tells me that Linux completely ignores mount points.

Say I mounted a filesystem (we'll call it fs2) on /foo/bar.
Fs2 contains a file called "file" in it's root dir.

Now say we wanted to open the path "/foo/bar/file", this article says that this happens:

lookup "foo" from rootfs inode - inode 1 on rootfs
lookup "bar" from inode 1 on rootfs - inode 2 on rootfs
lookup "file" from inode 2 on rootfs - not found

Notice how the lookup of "bar" returns an inode from rootfs, instead of an inode from fs2. Because how the fuck is rootfs supposed to know that "foo/bar" has fs2 mounted on it? all the linux technical documentation I've read on google do not fucking explain this.

http://codeforces.com/problemset/status/282/problem/A/page/1

However I don't want to scrape 'accepted' submissions, just 'wrong answer' ones, but the only way to get it to display 'wrong answer' ones is by using the filter on the right.

How can I make my scraper script select from the drop down menu and select the right filter then click apply? Or is this not possible?

(define (sum values)
  (if (empty? values)
      0
      (+ (first values) (sum (rest values)))))

do you just type with like a single finger

>>58752042
What I try to do is break every problem down into smaller pieces but I never come up with any elegant solutions for things.

>>58752083

data Nat = zero | succ Nat

add : Nat => Nat => Nat
add m zero = m
add m (succ n) = succ (add m n)

Dumb lispposter.

>>58751995
That's far less funny.

>>58752086
You need to send a POST request with verdictName set to WRONG_ANSWER.
Come on faggot it's basic shit.

>>58752117

With a standard number type:

add : Int => Int => Int
add m 0 = m
add m n = 1 + add m (n - 1)

anything written in java is by definition not elegant.

I know all of that, which is making me go crazy

This is Canada, very long waiting times.

>bad grades
I know that, but deep down I just feel really lonely and I can't study because I get depressed

All this plus I'm in second year without a clue knowing what to do, and the GPA pressure is making me go crazy

how do you guys list languages on your resume? I just list Python, C++, C. I've touched other languages academically but wouldn't be confident in saying I know them for interviews.
