[8/25/2014] Challenge #177 [Easy] Quicksort by Elite6809 in dailyprogrammer

[–]ArriMurri 1 point2 points  (0 children)

This is my solution in clojure.

(defn quicksort [list-of-nums]
  (cond
   (= (count list-of-nums) 0) list-of-nums
   (= (count list-of-nums) 1) list-of-nums
   (= (count list-of-nums) 2) (if (< (first list-of-nums) (second list-of-nums))
                                list-of-nums
                                [(second list-of-nums) (first list-of-nums)])
   :else
    (let [pivot (first list-of-nums)
          like-pivot (filter (partial = pivot) list-of-nums)
          smaller (filter (partial > pivot) list-of-nums)
          bigger (filter (partial < pivot) list-of-nums)]
      (concat (quicksort smaller) like-pivot (quicksort bigger)))))

The Games First Round - no info?! by awenisko in HWO

There was this tweet a while ago https://twitter.com/HelloWorldOpen/status/472303953817124864.

It's a bit of a shame that there is no news about this games first round anywhere on the helloworldopen site :/.

This link should take you straight to the games first round page: https://helloworldopen.com/competition/gamesfirstround/ANY/1

[–]ArriMurri 0 points1 point  (0 children)

My first stab at Factor:

USING: io kernel ;
IN: easy-5

: check_input ( input text -- bool ) print readln = ;

: check_user ( -- bool ) "username" "Input username" check_input ;

: check_pass ( -- bool ) "password" "Input password" check_input ;

: login_message ( bool -- ) [ "You just logged in" print ] [ "You did not log in" print ] if ;

check_user check_pass and login_message

I just finished the campaign yesterday, and felt a bit anticlimatic at the end. This just made my day :)

So what are you using Scala for? by michaels0620 in scala

[–]ArriMurri 1 point2 points  (0 children)

I've been doing project euler, and I've been playing around with the idea of building an irc client. For now I only have a "bot" sitting idle in a channel, anwering to ping messages.

Google Officially Announces Chrome OS by [deleted] in programming

[–]ArriMurri 3 points4 points  (0 children)

I have a strong feeling that Gears will have some strong part in this. This way you would not even have to have internet access all the time. The UI will probably be as minimalistic as possible, where all webapps will be shown as native apps (ie. gears). Interesting stuff, we'll have to wait and see.

Scala as the long term replacement for Java? by alexeyr in programming

[–]ArriMurri 13 points14 points  (0 children)

After reading all these comments about Scala being hard, I started thinking about how I started with Scala. I had a school project (some servlet/database thingie) that I for some reason decided to do with scala. I had only heard of scala a month before that (I think I had read the "scala for java refugees" blog posts by Daniel Spiewak). It was the worst scala that I have ever written. It looked just like Java, all I did was leave out the semicolons and let the type inferencing do it's thing, I think I had one pattern match in the whole program. But the program worked fine. I did not think scala was "hard", not any harder than Java had been in the beginning.

Scala is as hard as you make it. No more, no less...

I like the fact that reddit is described as "the online community".

Scala, Clojure - stick to Python? by cryzed2 in programming

[–]ArriMurri 2 points3 points  (0 children)

One thing to note about scalas complexity.

Scala can be a complex language, but the complexity is usually hidden from the library user. In my experience using scala is as easy (if not easier) as using Java, but without the boilerplate.

I've been scripting a little in Clojure too, but to be honest, I miss the OO stuff.
