iOS : A short list of PDF viewers I've tried

I've spent quite a bit of time thinking about how I can transition to ebooks for programming reference. I've had a e-paper Kindle for three years and haven't purchased a single physical book since. Typically with technical books I end up writing a lot of comments in the margins, adding page markers with notes on them and highlighting everything.

I tried reading PDFs on a e-paper Kindle and it doesn't work well at all. You can't adjust the font size, page drawing is painfully slow and the device isn't built well for my workflow. Kindles are perfect for relaxation reading, but not that great for much else.

I started looking for an iPad PDF reader and there are no shortage of those. I tried quite a few readers and read about a lot of others.

Adobe Reader (app link)
I used this for about a week. The page flipping speed was ok. It had trouble with large PDFs. Note taking wasn't that great and highlighting wasn't much better. For a free app it will get the job done, but I was looking for something better.

PDF Reader Pro (app link)
This started off as a promising app. Highlighting was ok and it the app was responsive. The problem I had was page turning wasn't that smooth. It had trouble zooming in a page and the interface wasn't that great.

iBooks (app link)
You can read PDFs with this and thats about all. No fancy features here.

Kindle for iPad (app link)
Limited note taking and highlighting. Not that great.

PDF Expert (app link)
This is by far the best PDF reader I have ever used. The interface is really clean and well laid out. It supports book syncing with dropbox so all of your comments and highlights are backed up to the cloud.  It also supports syncing with a Webdav Page turning is incredibly fast and supports border tapping and swiping. It will zoom in on a page so you don't see borders and it doesn't clip any of the text. It supports a page grid view so it's easy to find a page if you've lost your place. It supports tabs at the bottom of the app so you can have more than one book open at a time.

I really can't say enough good things about PDF Expert. I was hesitant paying $10 for an iPad app, but it's true that you get what you pay for. Anyone looking for a PDF reader should give this app a try. 


Javascript : Updating the search parameters with window.location

I ran into an issue with Firefox not navigating to a new address I set via windows.location. Here's an example of a url I was trying to set.


windows.location = "?page=account&this=that&foo=bar";

There's a property on the location object called search. When updating a partial url this should be used.

windows.location.search = "?page=account&this=that&foo=bar";

Flex / ActionScript 3 : Problem with ExternalInterface.addCallback

I'm adding some functionality to an existing Flex project that requires cross talk between ActionScript and Javascript. Reaching from ActionScript to Javascript is pretty easy. This can be done with the ExternalInterface.call. Calling from Javascript to ActionScript was a little tricker. Especially with local development.

You can use ExternalInterface.addCallback to create a bridge for Javascript to talk with ActionScript. There are a few more steps to make sure this is set up properly.

1) Make sure the id and name are the same in each AC_FL_RunContent function. Just changing one won't work. This way document.getElementById should always find the object on the page.
2) Make sure allowScriptAccess is set to always in each AC_FL_RunContent function. This updates the security setting so Javascript can access the Flash object.
3) If you're doing local development make sure to check Always allow in Global Security Settings Panel.

I found step 3 after wasting an entire morning looking around the internet. Without this I kept getting this warning.


*** Security Sandbox Violation ***
SecurityDomain 'null' tried to access incompatible context 'file:///foo/bar/project.swf'

Once you're project is finished you might want to change this back. Not sure what thing on the web wants to break your computer.

I heard you like popples


Here's something cool my wife is currently working on. She's working from a pattern but decided to make some changes along the way. It's coming along nicely.


If you're into plush toys you should check out her tumblr account.


She also has an etsy account where she posts things from time to time.

OSX : The tale of too many git clients

I'm starting a project that uses GIT for source control. I have a little experience using git but it has been mostly with github and their client for OSX. It took a little while to wrap my head around the way git works but I finally figured it out.

The only issue with github's client is that it only works with their site. I tried searching google for a few git clients and ran into far too many. I found two really good stack overflow pages that ranked different git clients.


Buried in there is a link to a review site that talks about a lot of the clients and gives good feedback on them.
