Once in a while I have a few questions from my classes about what music is playing over the speakers during down time or tests. This is some of the music I play for my classes, honed over a while.

I was speaking with a colleague today about ISO files/images in Mac OS X, and when he expressed his disappointment with existing software.
I said I would show him some cheap and easy ways to mount ISO files and how to backup any CDROM using Disk Utility.

Mounting an ISO on your Mac is accomplished using the hdiutil command.
To attach an image file,

1. you will first need to open up your Terminal.app
2.  type  hdiutil attach -readonly filename where filename is the full unix path of your file (just to be safe). When I was testing this my command looked like “hdiutil attach -readonly /Users/ck/Downloads/cdrom-1.33.iso”.
3. If you run into problems or find your image type says not supported, generally because it is a .cdr file, try hdiutil attach -imagekey diskimage-class=CRawDiskImage filename.

This should mount the image in your Finder sidebar as you would expect a normal CDROM would. If we are concerned with creating images with Disk Utility, that is as simple as dragging the inserted CD onto the Disk Utility application, or selecting it within Disk Utility and selecting New Image.

I also spent a good twenty minutes looking for the Excel 2008 Toolpak addon which Microsoft advertises in their knowledge base, unfortunately this link is broken and there is no place to download and install said addon.

Do not despair! The functionality you seek is actually included in Excel, you just need to go looking for it. If you check your formula bar/builder, you will find that the statistical tools you crave(like the nice correlation tool) are right there.

Enjoy!

Have you ever had an issue with someone sharing an iTunes library, and you want to quickly track down the IP of the offending user?

Here is a quick little guide on getting that done.

dns-sd is a service discovery application that can make tracking down users sharing various information quite easily. It also has a great API for accessing various information about local DNS information, and setting local DNS advertising quite easily.

First, an example:

dns-sd -B _daap._tcp
This command checks for bonjour iTunes shared libraries (daap protocol, tcp, .local subnet).
Output:
Browsing for _daap._tcp
Timestamp   A/R Flags if Domain Service Type Instance Name
9:31:12.844  Add  3  4 local.  _daap._tcp.   local’s Library_PW
9:31:12.844  Add  2  1 local.  _daap._tcp.   local’s Library_PW
local:~ local$ dns-sd -L "local’s Library_PW" _daap._tcp
Lookup local’s Library_PW._daap._tcp.local
local’s Library._daap._tcp.local. can be reached at 
local.local.:3689
(interface 1)
Flags: 1
txtvers=1 iTSh
Version=196609
MID=************
Database ID=D18C43A55BFAC99B
dmv=131078
Version=196616
OSsi=0x1F8
Machine Name=local’s Library Media
Kinds Shared=3145839
Machine ID=************
Password=1

With these commands, it gives you the hostname, which you can always resolve by pinging it. This is a slightly edited output for readability. (spaces and newlines are escaped in the shell, but you see all the slashes)

How is this better than other solutions like Flame or Bonjour Browser?
Well, with this approach, we can actually script the entire event into one bash script, without too much work.
A minute of checking the man pages for sed and cut yields:

#!/bin/bash
# create semi-random filenames for writing and reading to
tempfoo=`basename $0`
TFILE=`mktemp /tmp/XXXXXX` || exit 1
TFILE2=`mktemp /tmp/2XXXXXX` || exit 1
# grabs browseable list of bonjour shared libraries
dns-sd -B _daap._tcp 1>$TFILE &
# grab the process identifiers for the dns-sd process WHICH NEVER STOPS
TFILE_PID=$!
sleep 1
# takes the last library in the list and formats it for dns-sd -L
res=$(tail -n1 $TFILE | awk '{gsub(/[ ]+/," ")}1' | cut -d' ' -s -f6-)
# read the protocol and then name in, allows us to use different protocols in the future 
read -r protocol name << "$res" 
# look up specific libraries
dns-sd -L "$name" "$protocol" 1>$TFILE2 &
# grab the process identifiers for the dns-sd process WHICH NEVER STOPS
TFILE2_PID=$!
# we have to wait a second because dns-sd -L can take a while to respond
sleep 1
res2=$(cat $TFILE2 | awk '{gsub(/[ ]+/," ")}1')
# for some reason cut wasnt respecting the spaces, but in another var it worked fine
ip=$(echo $res2 | cut -d' ' -f10| cut -d'.' -f1-2)
if [[ "$ip" == "" ]]
then echo "No computers are sharing their libraries"
else ping $whoa1
fi
# kill the dns-sd processes
# remove the temporary files
kill $TFILE_PID
kill $TFILE2_PID
rm $TFILE
rm $TFILE2

…and by a minute, I meant more like an hour. I commented most of the material, and the source can also be found at http://gist.github.com/481921.

A lot more went into this than initially expected, but that is always the case when it comes to bash.

I just wanted to recommend a great site with really good completely free screencasts, http://teachmetocode.com/.

I never get paid for any of the things I link to, unless they are explicitly in an advertising bar, and so I don’t do it unless I absolutely love the product. I really like teachmetocode’s range of things to help you coding, from outside in development with cucumber (writing functionality as a function of prewritten sentences which preview functionality), a great intro to github and git, to more advanced rails concepts.

The format is also interesting because it has many experts, not just the site maintainer, so you get a slightly different way of looking things, but a consistent interface which shows you exactly what they are doing; there are no smoke and mirrors in teachmetocode, and with some of these screencasts under your belt, you’ll feel more confident in your Ruby learning.

Note: this is definitely for people new to Ruby/Rails. Experienced codes may pick up a few tricks, but its geared towards a learning audience.
