Then you can simply do

[user@host]# echo "1" >> numbers.txt
[user@host]# echo "5" >> numbers.txt
[user@host]# cat numbers.txt | min

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont

There you will see a string value (0 => “Lucida Console”) or something similar, to add your own fonts which will show up you have to add a new string value with the name of your required font (00 => “Consolas”). Subsequent fonts can be added at (000 => “someotherfont”) etc. I then had to do some dicking around to get the properties to stick on my command prompt shortcut but eventually I had a nice looking font for my command line hacking. Best of luck to you!

#include <iostream>
#include <string>
#include <boost/foreach.hpp>
#include <boost/tokenizer.hpp>

using namespace std;
using namespace boost;

int main(int argc, char** argv)
{
   string text = "token, test   string";

   char_separator<char> sep(", ");
   tokenizer<char_separator<char>> tokens(text, sep);
   for (tokenizer<char_separator<char> >::iterator it = tokens.begin(); it != tokens.end(); ++it)
   {
      cout << *it << "." << endl;
   }
}

And my personal favourite is to push the result of the tokenization into a vector/list/stl container.

#include 
#include 
#include

#include 
#include 

using namespace std;
using namespace boost;

int main(int argc, char** argv)
{
   string text = “token, test   string”;

   list tokenList;
   split(tokenList, text, is_any_of(”, “), token_compress_on);
   (list::iterator it = tokenList.begin(); it != tokenList.end(); ++it)
   {
      cout << *it << "." << endl;
   }
}

So awesome!

Stolen from the lazy programmer and reposted here for my own reference.

ls -las /dev/disk/by-uuid/

blkid /dev/hda1

Then it was as simple as editing my /etc/fstab to replace the reference to /dev/hd[ab]1 with a reference to the uuid and I was done

/dev/hda1 /data ext3 defaults,errors=remount-ro 0 1

to

UUID=21819e49-70fa-477e-9937-bd04e0550aab /data ext3 defaults,errors=remount-ro 0 1

Thanks to f241vc15 for pointing me in the right direction.

Turns out there is a standard switch which I hadn’t found! The accept switch “specifies an action for automatic conflict resolution. Possible actions are postpone, base, mine-full, theirs-full, edit, and launch“. So to just use the local version (safest):

svn up --accept mine-full directory

a = 'test'
b = nil
both = a && b       # both == nil
both = a and b      # both == 'test'
both = (a and b)    # both == nil

In the second case the statement evaluates as

(both = a) and b   # the result of this statement would be false, but it's never used or assigned.

So the upshoot is ALWAYS use ‘&&’ to avoid unintentional failure!

(Example borrowed from PJHyett.)

I needed to knock up a Ruby script recently that orchestrated some external processes using backticks. However something was going wrong and I need to temporarily peek into the inputs and outputs of the external programs. Ruby bend-ability to the rescue:

module Kernel
  alias_method :real_backticks, :'`'

  def `(cmd)
    puts "`#{cmd}` => #{output = real_backticks(cmd)}"
    output
  end
end

 i=250
 while [ $i -lt 604 ]
 do
   echo $i >> /home/dev/bdk_changes.txt
   svnlook changed bdk -r$i >> ~/bdk_changes.txt
   i=`expr $i + 1`
 done

(apparently the same thing can be done with svn log –verbose > ~/a.text.file). Then after finding that the offending revision was 403 I wanted to copy the directory from revision 402 into my working copy; according to the svn manual this is accomplished using

 svn copy –revision 402 http://svn.server/repos/path/to/deleted_file ./deleted_file

this didn’t exactly work for me tho as I got the following error

 D:BDK>svn copy –revision 402 http://svn.vlc/svn/bdk/trunk/data .
 svn: ‘/svn/bdk/!svn/bc/617/trunk/data’ path not found

well duh of course you can’t find the data directory at revision 617, that is why I want revision 402 (like I specified)… oh well lets try the following

 D:BDK>svn copy http://svn.vlc/svn/bdk/trunk/data@402 .
 A    dataPTImporter
 A    dataPTImporterPtRoutes.csv
 Checked out revision 402.
 A         data

woot! I now have my directory back again!

File.open(filename, 'r') do |f| f.readlines end
IO.readlines(filename).each do |line| end
lines = IO.read(filename).split("n")

thanks to Partro for the outline along with the following three points

• File.open gives you a file handle you can stream from
• while the IO methods read it all in at once
• read gives you a single string of the contents, readlines splits it on line endings
