The developer Levi Cook has taken the domain lvh.me (short for: local virtual host me), that resolves to the localhost IP address 127.0.0.1 and supports wildcards (accommodating dynamically created subdomains). No network configuration needed!

Especially useful when developing an application with dynamically created subdomains. I found out about this from http://github.com/fortuity/rails3-subdomain-devise/

However, where he says that this worked for him:

sudo env ARCHFLAGS=”-arch x86_64″ gem install pg

… I had to put this in my .bashrc:

export ARCHFLAGS=’-arch x86_64′

Then run:

$ gem install pg –include dependencies

At that point I was good to go. Not sure why his suggestion didn’t work for me, but it kept giving me this error:

$ sudo env ARCHFLAGS=”-arch x86_64″ gem install pg

Adobe AIR 1.5.3 Release Notes

Adobe AIR Team blog post announcing AIR 1.5.3

I first read about Ignite Portland last year right after IP6 (Ignite Portland 6). I knew I had missed something cool, so I kept an eye peeled for the announcement of IP7. It finally happened last night.

I wasn’t sure going into it what to expect. The website describes the creators as “geeks”, there are techy sponsors, and if you dig a little further you’ll find an Ignite Community site that is sponsored by O’Reilly.

But the topics of the talks are generally non-geeky, as you can see here in the list of last nights presentations:

* Rick Huddle – Why we love DB Cooper
* Mike McClure – Roasting Coffee at Home: It’s easier than you think!
* Clifton B – Why Highway Communication Sucks and How We Can Make It Suck Less
* Michael Weinberg – Thanksgiving 2.0
* Jason Duerr – Pump Up Your Volume: Building a Pirate Radio Station
* Crystal Beasley – Ecstatics, Zealots & Mass Hysteria : How we collectively lose our minds
* Douglas Wolk – Kant’s “Critique of Aesthetic Judgement”: Drastically Condensed Awesome Version
* Adam DuVander – The Donkey Man is not on Facebook
* Colleen Wainwright – My bloody epiphany
* Phil Earnhardt – Robots Growing Up: The Future of Robotic Movement
* Marcus Miller – How to cultivate a wisdom of craft.
* Lou Alvis – Human Systems Analysis. What Are People Doing?
* Curtis C. Chen – How to Solve Any Puzzle in Less Than 47 Minutes
* Kelly Jo Horton – Confessions of a Dating Ninja
* Brett Stern – Rural mailboxes
* Elena Moon – How to Capture and Eat Your First Roadkill Deer
* Ward Cunningham – Becoming Bike Oriented
* Randal Schwartz – Karaoke for fun and profit
* Christian Howes – Inappropriate terms to use in an American business meeting if you are a brit!
* Kent Bye – The Resurgence of Hula Hooping

I showed up early, grabbed myself some pizza and a beer, and took a seat. A lot of laptops were open and a lot of iPhones were glowing. I decided to watch the tweets for #ip7 and they started flowing in at a steady rate. It kept me entertained until the start of the show. I’ve actually never been at an event like that and watched the tweets come flowing in live as it was all happening — knowing that they were all originating from those right around me. I knew that @skinny was ‘absofrakkinterrified’ about giving her talk (she kicked ass by the way). I also knew that another one of the presenters, @dropkickdesign was wanting “Less talky talky more beer poury poury” in the beer line.

Then it started. There was no intro, no MC, just a clock that started counting down. Rick Huddle took the stage. From then on it was back to back 5 minute presentations, with about 10 seconds in between. It was fast paced. The topics were of all sorts. The crowd was relaxed and fun, and the speakers were all great.

I won’t go into detail on all the topics here. Some were plain funny, some were downright moving, and others were simply educational.

You can watch the stream here.

Thanks to everyone who put Ignite Portland together, and all the volunteers. It was an awesome time!

Create a file called ‘showHiddenFiles’
in Terminal, type:


chmod +x /path/to/showHiddenFiles


Make sure the location is on your path. I just use /usr/local/bin since it’s already on my path.

Edit that file with these contents:


#!/bin/sh
defaults write com.apple.finder AppleShowAllFiles $1
killall Finder


Now whenever you want to hide/show hidden files, just launch Terminal and type:

% showHiddenFiles true
– or –
% showHiddenFiles false

And don’t forget you can just type the first few letters (i.e. ‘showH’), then hit TAB and Terminal should auto-complete the file name for you. Then you can just add ‘true’ or ‘false’.

Assuming you’re using bash:

Launch Terminal

% pico ~/.bash_profile

Add a line with a variable followed by whatever command you what it to perform, such as:

webroot='cd /Volumes/apache/webroot'

CNTRL-X, then press ‘y’ to save the file and exit edit mode
now restart bash_profile;

% source ~/.bash_profile

That’s it!
Now anytime you want you can launch Terminal, simple type % webroot, and you’ll be taken to ‘/Volumes/apache/webroot’

Now will all the typing this will save you, there’ll be more time for beer at the end of the day.

Let’s say you often go to /Volumes/development/depot/mainbranch. Let’s create an alias to that called ‘mb’ for ‘mainbranch’ (this can be whatever you want, of course.
Simply launch terminal.
Type: alias mb=’cd /Volumes/development/depot/mainbranch’
Done!
Now just type ‘mb’ at the command prompt and you’ll be taken directly to that directory!
Sweet!

Note, you can also do the same to launch applications:
alias tx=‘open /Applications/TextEdit.app/’

var myObj:Object = {x:1, y:5};
for (var i:String in myObj)
{
    trace(i + ": " + myObj[i]);
}

However, if you have a custom value object, that doesn’t quite work. But what you can do is use describeType() to create an XMLList version on your VO.

var vo : SearchVO = data.getBody() as SearchVO;
// create an XMLList version of the VO
var varList:XMLList = describeType(vo)..variable;

// loop through the property list
for(var i:int; i < varList.length(); i++){
    // output the property name and value
    trace(varList[i].@name+':'+ vo[varList[i].@name]);
}
