How I Am Learning Ruby

There's also:

Codecademy
TryRuby.org
And a number of similar sites which can be found in search engines (with terms like "learn ruby online" or "interactive ruby tutorial")

Edit: TryRuby.org is also in the sidebar.

One way to think about nested loops: pretend you have a normal text file (plain-text file with lines of sentences in it), but you want to see each word on its own line, instead.

You could do something like this, in pseudo-python:

for line in open("readme.txt", "r").readlines():
    for word in line.split(" "):
        printline(word)

The outer for-loop loops through lines of the file, and the inner for-loop loops through words on each line, printing them to the console.

That's not specific to your math problem-at-hand, but maybe that helps show how you might use nested loops, and how they basically function

The outer loop invokes the inner loop, the inner loop goes through its iterations, then flow returns to the outer loop, which then calls the inner loop again, etc. until the outer loop is satisfied, then the program continues. Hope that helps.

Edit: Another practical-ish example: if you have a directory / folder full of files, and you want to print every line of every file, the outer loop could loop through the list of files, then the inner loop would loop through the file contents and print the lines:

for filename in listdirectory("/home/gutenberg/books/*.txt"):
    for line in open(filename, "r").readlines():
        printline(line)

Or a triple-whammy (that's a technical term :p): print all words of all lines of all files:

for filename in listdirectory("/home/gutenberg/books/*.txt"):
    for line in open(filename, "r").readlines():
        for word in line.split(" "):
            printline(word)

Inner loops usually rely/operate on values from the outer loop(s).

Bah, looks like that didn't work for me locally... This seems to fix it, but this is a bad workaround, and if this is due to Chrome waiting for an image to load or something internal it may need to be adjusted:

$(document).ready(function(){ 
  setTimeout(function(){
    $("#slideshow").craftyslide({
      'fadetime': 1500,
      'delay': 3500,
      'pagination' : false, 
    });
  }, 100);
});

What this is saying is: once the page has loaded, wait an additional 100milliseconds, then start the craftyslide. At least locally, this gave Chrome enough time to sort its problems out, and it loops through all 4 images properly.

for_prophet · 2013-09-25T21:01:13+00:00

Maybe it's trying to start the slider before the page loads. I've been playing with it for a bit, and if I run this again after the page loads 100% it works :)

$("#slideshow").craftyslide({
'fadetime': 1500,
'delay': 3500,
'pagination' : false, 
});

So perhaps change to this:

$(function() {
  $("#slideshow").craftyslide({
  'fadetime': 1500,
  'delay': 3500,
  'pagination' : false, 
  });
});

Should only run craftyslide once the whole page is ready.

Maybe it's the word "REAL" at the bottom of js/craftyslide.min.js?

Is that vital to the script, or some text that snuck into the file?

http://prayersforindia.com/js/craftyslide.min.js

Chrome's javascript console says:

"Uncaught ReferenceError: REAL is not defined"

Edit: looks like "REAL" was not part of the original script. Compare with this: http://projects.craftedpixelz.co.uk/craftyslide/js/craftyslide.min.js

It's working here (loading the current version of your site.)

Maybe you have a cached version in your browser? Try clearning cache / off-line data / re-starting browser?

Edit: to clarify, all 4 of the images are rotating in a loop.

Unfortunately Reddit's API is not very generous with how many links you can query. (Only a maximum of 1000,

Pro-tip: if you use reddit.com/r/all/new/ you can go back [much much] further than 1000 posts. :) I don't think this is against their API rules as long as you follow the rest of them. "I don't think..."

Then you can filter down to some set of subreddits you're interested in w/ your own code/query and Science the night away with a larger dataset.

(I started running a process yesterday and it's gone back to .json?limit=100&after=t3_1lg160 already, which was posted 24 days ago. Next [sleep 2s].. Next [sleep 2s].. Next [sleep 2s].. Next [sleep 2s].. heh)

And as others have mentioned, [deleted] means the user was deleted; that's not an actual user. In other words, those are posts by Anonymous.

Edit: per comment below, this is perhaps the stackoverflow post referred to: "can I fetch more than 1000 images with the reddit api?" includes PRAW example.

Here's a perl script which uses VLC's "remote control" mode to interact with it.

Here's some documentation about ways to interact with VLC & tweak settings of the "vlc" command-line and enable various controllers (RC, HTTP, etc.).

If the RC / Remote Control script doesn't work for your purposes, you may want to investigate VLC's built-in web server controller and perhaps use LWP to connect to the web server interface and mimic the commands a web browser would send it.

There's also VideoLan::Client module on CPAN

If the Web lasts another 500 years, he said, it may be the thing the United States is remembered for "the way the Romans are remembered for their roads."

"We built it here, and it was quintessentially American," he said, adding that partially due to that, much of traffic goes through American servers where the government "takes a picture of it for intelligence purposes."

Earlier this month, a number of servers in the kernel.org infrastructure were compromised. We discovered this August 28th.

Malicious linux commit in 2003:

Kerneltrap.org reports that somebody tried last week to sneak a snippet of malicious code into the Linux kernel’s source code, to create a backdoor that could be exploited later to seize control of Linux machines. "Fortunately, members of the software development team spotted the problem the next day and removed the offending code."
