So I wrote a little perl script that renames all RAZR pictures to YYMMDDhhmm.jpg so that they can be easily sorted in chronological order by any file browser.  You’d think a big international company like Motorola would be able to respect the ISO 8601 standard by now.

SQLite3 and the necessary driver gems come preinstalled on OS X Leopard, but if you don’t have the Ruby bindings installed it’s as simple as:

sudo gem install sqlite3-ruby

You can always change which db your Rails app is using by changing your config/database.yml.

Lets say you want to forward mail from your Lotus Notes account but want to strip attachments, you’ll definitely want to try the following script. It’s perfect for sending your mail to your sexy new iPhone without racking up ridiculous bandwidth charges.

This works in Notes 8, but has not been tested in earlier versions. Also be sure to replace YOUREMAIL@MAIL.COM with an external email address. Credit should go to Simon Lacasse who did the nitty gritty work, I’m just making sure others can benefit from it.

Sub Initialize

Dim session As New NotesSession
Dim db As NotesDatabase
Dim collection As NotesDocumentCollection
Dim memo As NotesDocument
Dim doc As NotesDocument
Dim j As Integer
Set db = session.CurrentDatabase

Set collection = db.UnprocessedDocuments

For j = 1 To collection.Count
Set memo = collection.GetNthDocument( j )
''If Not( memo.SentByAgent ) Then

Set doc = New NotesDocument( db )
Call doc.CopyAllItems( memo, True )
Dim rtitem As NotesRichTextItem

Set rtitem = memo.GetFirstItem("Body")

doc.Form = "Memo"
doc.Subject = "From :" + memo.From(0) + ":" + memo.Subject( 0 )
doc.Body = memo.Body
doc.Principal = memo.from(0)
''doc.InetFrom = memo.SMTPOriginator
doc.ReplyTo = memo.from(0)

Call doc.Send( True, "YOUREMAIL@MAIL.COM" )
'Call doc.Send( False, "Put another EMail address here" )
''        End If
Call session.UpdateProcessedDoc( memo )
Next

End Sub

Leopard (OS X 10.5) has its fair share of goodies, including a new and improved terminal client with *gasp* tabbed windows. I thought this feature would be great news, since as I wouldn’t need to install the venerable iTerm in much of the same way that Spaces has supplanted VirtueDesktops. After a week though I’ve gone back to iTerm, as it became painfully obvious that the Window Groups features of the Leopard terminal couldn’t hold a candle to the bookmarking features in iTerm. The Window Groups in terminal fail to retain any useful information such as which host you are connected to, and you’re manually forced to ssh back to where you were before, this is something that the bookmarks in iTerm solve easily. So close Apple, yet so far…

I think Marc Andre Cournoyer’s review impressed me the most, mainly that “…[it] is an exploit to be able to code a live app in front of a crowd like this.“ It’s a testament to the power of Rails and I’m just glad the Roles portion didn’t bomb the way it had during my rehearsals at home.

I was especially impressed by Chris Scott’s demo of the Ext JS framework. Sorry Darin, but there are some pretty nice features in Ext that will make me want to take a closer look. Terje Tjervaag’s demo of Firebug was convincing enough to make me wonder why I hadn’t already installed it yet. Used it at work today to great effect. You can read more reviews of the night here and here, while photos have been posted on Flickr and videos might pop up on Youtube.

I learned this lesson on my own and it bears repeating, because even after all these years I still catch myself doing it sometimes. It’s Friday, you’re tired, and when your guard is down that’s when you start doing stupid things to your code.

So go write some documentation or as Marc-André Cournoyer suggested, fix the little things that you told yourself you’d do later but never did or add some tests. Just stay away from major changes on a Friday afternoon!

Although user authentication may sound like an advanced topic, it will be aimed mostly at the novice Rails developer as a showcase of how easy it can be to implement advanced features such as user security and roles in a Rails application. I hope to touch on a few items including the excellent Acts As Authenticated, roles and salting. If there’s anything in particular you would like to see, drop me an email.

#if $TEST_END doesn't become an empty string,
#then OBJECT_NAME ends with "(" so we strip it
TEST_END=$(echo "$OBJ_NAME" | grep \($)
[ -z "$TEST_END" ] || OBJ_NAME=$(echo ${OBJ_NAME%\(})
echo "OBJ_NAME is : $OBJ_NAME"

The sharp eye amongst you will notice that this works for FOO( but not for FOO(NANY. If you want to strip everything after the ( and including the ( the you want this:

TEST_END=$(echo "$OBJ_NAME" | grep \()
[ -z "$TEST_END" ] || OBJ_NAME=$(echo "$OBJ_NAME" | awk '{split($0,a,"(");print a[1]}')
echo "OBJ_NAME is : $OBJ_NAME"

Notice how the grep no longer uses the $ anchor to match a ( at the end of the line? Now if $TEST_END isn’t empty, then we have a ( in our string, so we split on that and return everything to the left (first element in the a[]).

The first presentation topic was improving tests, it was given by Marc Cournoyer and included a hilarious introduction to a somewhat advanced topic. The next presentation was given by Carl Mercier, who introduced the extremely useful HAML, which appears to cut the code in your views by half by generating HTML using a simplified indentation scoped ruby based markup. Very simple and very powerful stuff and I’ll be trying it shortly.

Overall the people who attended the meetup were great and I look forward to the next one. It’s so good to see a vibrant developer scene in Montreal.
