http://www.mycelery.com

We can begin to gather at 5:30PM with presentations/lightning rounds/

I'll Be there.

I've been attempting to dust off and update my using vim
presentation. Hopefully I get it cleaned up and updated enough to get
give a quick presentation on how to get started with using it.

I'll be discussing the use of credit card magnetic strip readers and
barcode scanners in web aplications.

Also, I need everyones help to finish a ruby script to identify
duplicate directories within a given path. It's not enough to just
know the thousands of files that are duplicates. To know that a
directory and it's underlying "branch" is duplicated on a hard drive
can make cleaning a filesystem less painful. My goal isn't to download
a program and run it, but to write the script in Ruby! (Gen 1: Compare
using file and directory names, Gen 2: Compare using MD5 hashes of
file content, Bonus: Knowing when a branch is 98% equal to another
branch)

Sounds like a fun activity Jim.  I will of course be there as usual and hopefully not have to leave too early :)

Can you use python? There is a really slick library that compares two
directories and their contents. I'll follow up with details when I
get home.

Though I walk through the valley of the shadow of ruby, I shall fear
no rails for I carry the power and word of python in my heart!

Oh thou parsel tongued one. Your one line comprehensions are no match
for our multi-line block expressions. You have been blinded by the
light of your "white" space. Seek ye out the true path to dynamic
wisdom.....

...and learn Lisp!

Bet you didn't see that coming,

Mark

[Gemma Hentsch]

I offer the way to true power, free from your feeble magic, lack of requirement for beautifully formatted code, and your strange and sinful monkey patching....

- the corruptor of innocent ruby programmers

[Edward Prevost]

Is that you Scala?!

[JimCifarelli]

Hi Tom,

There may be a slick library for Ruby too.... I haven't looked. If
anyone out there has some wisdom with regards to this issue, bring it!

gist of sample python code that compares two dirs and copies to a third

It's looking like I might not be at RB tonight. Sylva thinks she might
be starting very early labor. If I don't make it have a good time.

In Soviet Russia, Tom stalks YOU

Moving to Russia!

[Andrew Badera]

Or perhaps Russia is moving to you?

Making room for Russia in the guestroom!

I thought this was a good overview, as we had touched on some of this
at the last meeting.... food for thought:

[Edward Prevost]

LibXML?

Given:

<this>
<that id="1" which="was" those="that" are="characteristics"/>
<that id="2" which="was" those="that" are="characteristics"/>
<that id="3" which="was" those="that" are="characteristics"/>
<that id="4" which="was" those="that" are="characteristics"/>
</this>

What am i doing wrong here:

require 'open-uri'
require 'xml'

p 'start xml test'

url = 'https://path/to/uri/that/returns/the/above/given/'
xml = open(url).read
source = XML::Parser.string(xml)
content = source.parse

p "consumed url"

nodes = content.root.find('/this/that')
nodes.each do |thing|
p thing
end

-Ed

[Ryan Scott Lewis]

What errors are you getting?

This is working fine for me.

test.xml:

<this>

<that id="1" which="was" those="that" are="characteristics"/>

<that id="2" which="was" those="that" are="characteristics"/>

<that id="3" which="was" those="that" are="characteristics"/>

<that id="4" which="was" those="that" are="characteristics"/>

</this>

xml.rb:

require 'pathname'

require 'xml'

xml = Pathname.new('test.xml').expand_path.read

source = XML::Parser.string(xml)

content = source.parse

nodes = content.root.find('/this/that')

nodes.each do |thing|

  p thing

end

[Edward Prevost]

no errors, just no output...
