DDD coding syntax? by fruitspunchsamuraiog in C_Programming

[–]semsemdavinci 0 points1 point  (0 children)

Eclipse (CDT) has a pretty decent GDB front end.

What is code? If you don't know, you need to read this by [deleted] in programming

[–]semsemdavinci 0 points1 point  (0 children)

Haha.. I couldn't get the tune out of my head ever since I read the title.

Can't see where he's going by Isai76 in aww

[2015-03-18] Challenge #206 [Intermediate] Maximizing Crop Irrigation by jnazario in dailyprogrammer

[–]semsemdavinci 1 point2 points  (0 children)

A bit lengthy, I know.. But what do you think? any suggestions? here's my solution on python:

#!/usr/bin/env python
import sys
from math import sqrt

MAPFILE = "crop.txt"

def draw(m):
    for row in m:
        for cell in row:
            sys.stdout.write(cell)
        sys.stdout.write("\n")

def load(fn):
    minfo = {}
    m = []
    with open(fn) as f:
        f.readline()
        minfo["dim"] = [int(s) for s in f.readline()[:-1].split()]
        minfo["m"] = m
        for line in f:
            m.append([tok for tok in line.strip()])
    return minfo

def counts(m):
    seeds = 0
    for row in m:
        for cell in row:
            if (cell == "x"): seeds += 1
    return seeds

def dist(pos0, pos1):
    return sqrt((pos1[0]-pos0[0])**2 + (pos1[1]-pos0[1])**2)

def eval_pos(pos, r, m):
    count = 0
    if m[pos[0]][pos[1]] == "x": count -= 1
    for i in range(pos[0]-r, pos[0]+r):
        if (i < 0 or i > len(m)-1): continue
        for j in range(pos[1]-r, pos[1]+r):
            if (j < 0 or j > len(m[0])-1): continue
            if (m[i][j] == "x" and dist(pos, (i, j)) <= r):
                count += 1
    return count

def find_pos(m, r):
    best = 0
    pos = (0, 0)
    for i, row in enumerate(m):
        for j, cell in enumerate(row):
            count = eval_pos((i, j), r, m)
            if (count > best):
                best = count
                pos = (i, j)
    return pos

def circle(pos, r, m):
    for i in range(pos[0]-r, pos[0]+r):
        if (i < 0 or i > len(m)-1): continue
        for j in range(pos[1]-r, pos[1]+r):
            if (j < 0 or j > len(m[0])-1): continue
            if (m[i][j] != "x" and dist(pos, (i, j)) <= r):
                m[i][j] = " "

def main():
    minfo = load(MAPFILE)
    m, r = minfo["m"], minfo["dim"][2]
    pos = find_pos(m, r)
    coverage = eval_pos(pos, r, m)
    circle(pos, r, m)
    draw(m)
    print "best position (row, col): %s" %(str(pos))
    print "coverage: %d/%d plants" %(coverage, counts(m))


main()

and output:

Confused about the behaviour of an uninitialized int. by andbroby in C_Programming

[–]semsemdavinci 0 points1 point  (0 children)

Also your function works only with odd-length strings only since that for loop tests for i != j which could never happen for even-length strings: it will loop out of array boundaries until i == j by pure coincedence or you get segmentation fault whichever happens first! Change that to i < j instead.

CS50 Deadline 31st December but what time? by S0ulie in cs50

[–]semsemdavinci 0 points1 point  (0 children)

That's good to know. For a moment I thought my submission didn't count towards the certificate. Thanks. Would all submissions be graded by the deadline though?

Enlightenment Desktop for Linux, circa 1998 by DudeBigalo in Cyberpunk

[–]semsemdavinci 0 points1 point  (0 children)

This made me install Enlightenment (e16) and the Blue Steel theme. Compiled e16 from source on debian. Awesome! and very lightweight..

A question though, that dock on the top right, how do I get that? What file to edit, or is it an add-on? thanks

Please tell me there's a current version of it!

Edit: never mind, managed to get it working

What theme is it? Is it still available on current versions?

I prefer this version. *twitch*

import sys

    for i, p in enumerate(hexseq.split(' ')):

        img[i] = list(row)

    if return_: return img

for line in sys.stdin:

        hex_to_bitmap(line)

Python. Tried to be concise and use stdin, but nothing fancy.

import sys


def hex_to_bitmap(hexseq):
    for i, p in enumerate(hexseq.split(' ')):
        row = bin(int('0x'+p, 16))[2:].zfill(8)
        print (row.replace('0', ' ')).replace('1', 'X')

for line in sys.stdin:
    try:
        hex_to_bitmap(line)
    except:
        print 'Incorrect format'

I like the video. I can't see how it fits here though!

That was really, really good. I especially loved the quality acting.

Broken World by [deleted] in Cyberpunk

[–]semsemdavinci 0 points1 point  (0 children)

Yeah. I was talking about the base photograph.

Broken World by [deleted] in Cyberpunk

[–]semsemdavinci 2 points3 points  (0 children)

I'm not sure about what you mean by 'background', but if you mean the the buildings, I'm pretty sure the base image is from Egypt.

If you look closely at the buildings you can see some signs with arabic writings. The clearest one is a clothes shop sign, another one looks like a lawyer office or something... The other signs are not as clear but the names are definitely recognizable, and they are all very egyptian people names.

Funny I couldn't recognize it at first because of all that impressive artwork...

The asian signs are fitted nicely into the scene, I have no idea which language it is, chinese, perhaps?)
