Exciting times indeed.

Raven and I are really excited about this event and can't wait to see you there!

I finally finished Episode 6 of The Core Animation Screencast. Man is is way over due (sorry!). It a bit long again but its really worth it (I think, but you will have to be the judge). In this episode we wrap things up with the final bits of transformation and filter goodness so that we get a really nice looking app.

Here is a teaser screenshot for the curious. The pics were taken by my amazingly talented wife on a recent trip to the Grand Canyon.

This has been a particularly fun series to put together. I really enjoy doing screencasts. If you have an opinion on what would be good to have next please let me know. I'm thinking an album art city would be fun to build but there is so much to cover for all the folks new to the platform. A nice Xcode intro or IB how too would be fun.

I got the next chapter in Gala Factory pushed out to the app store, just waiting on apple review. In the mean time please check out the demo video on youtube, and then line up to buy a thousand copies. Thanks!

Despite the mass of folks that got it wrong (specifically Matt Asay Red Hat did not send me the C&D letter, and my essay was not really about C&D's anyway). The dust up about the trademarking of Open Source projects was quite interesting.

Hopefully (but unlikely) the corp lawyers that send out the C&D's will read this and learn.

I'm totally stoked to say that my Dot Game has made it into the top 50 of all games on the store!

Buy early, Buy often!

Hard to believe that its finally here. I am really excited and can hardly believe that I have stuff there!

I am constantly blown away that the cool winding and twisting of life... I am done the Core Animation book, now just waiting for the iPhone NDA to lift so we can ship it. I started a book on iPhone for the prag's, which is very very fun and cool too.

I don't post much here because I spend most of my time on PrEV these days. Thanks for stopping by...

I finished Episode 4 up last night and the gerbils (i.e. Mike Clark) @ PragProg already turned it into a downloadable movie. You can grab it here.

This episode came in a bit long (at 42 minutes) but I could not think of what to delete. The main thrust of the episode is introducing 3D transformations and in order to make that happen I did a bunch of refactoring to the app so the layers would be setup to make beautiful cover flow goodness. At first I was thinking it would be good to just make the refactoring happen off line and then paste it in as canned code. After running though half the episode doing that I thought I was just leaving out too much good stuff about debugging tips and refactoring process. So anyway I put it in and it came in big.

Hope you enjoy it!

iPhone, key arrived, os installing, nothing to be said, NDA and all that, very excited...

Lame attempt to be funny, hard to be silent.

Scotty was kind enough to have me on the Mac Developer Roundtable tonight. If you are interested in WWDC or iPhone SDK please have a listen. It was tons of fun! Thanks again Scotty!

For those of you coming here from Scotty's site check out my Core Animation blog, its probably more relevant as this is my java blog...

As I documented here my poor old PPC mini was having trouble keeping up with the success of my wife's iPhone Games so I bought and configured a new Intel mini and shipped it off last week. It went on line yesterday and is now barely above 10% CPU usage (the PPC mini was at 100% since ballblast came out).

I took the opportunity to upgrade to Roller 4.0 and update the theme for my blog.

Way back in college I had the great privilege of working on a NeXTCube (started on system 0.9, yes I'm old...) with Mathematica doing some really cool non-linear stuff. It was my first exposure to Unix (which of course spoiled me rotten) and I was hooked. After the end of the semester I managed to land a job building code on the NeXT (doing 3d visualization of stress in materials). I had no idea what I was doing so I bought a book on object oriented programming, a book on smalltalk and a book that was a collection of research papers that mentioned Objective-C. I did not sleep much, got a second credit card and bought a NeXTStation (or pizza box as they were called). After I bought that baby (25MHz, 8MB Ram, 105 MB scsi hard drive, oh yeah!) I really did not sleep or study my aero space engr stuff either :) I still have it BTW and it boots just fine into NeXTStep 4.0, I put a 512MB SCSI disk in it (before I retired it). It also has the printer if anyone out there is in great need of a 25MHz 8MB computer I'm your guy.

After I graduated I looked around for a NeXT related job but nothing happened before my offer to go work at Rockwell Int. at NASA's Johnson Space Center in Houston expired so I took the job @ NASA and did some cool stuff. But other things were in store...

About 6 months into my full time employment I got a call from one of the consulting companies that I'd sent my resume to and they had some work doing NeXT training for Meijer. I jumped on that job in a second. While I was sad to leave behind astronauts, the space shuttle etc. The chance to work on NeXTStep full time was too tempting. That was 1992. I did professional NeXT stuff until 1998 when I jumped on the Java bandwagon and did a Java startup or two. Then went back to consulting doing enterprise java stuff etc etc, a lot of which has been documented on this blog...

Now to the point of this rather lengthy reminiscence. In November of 2007 I quit a great Java related gig to give the OSX world a shot (OSX is NeXTStep for those that don't know) and to focus on an OSX book for the Pragmatic Programmers. The book is finally beta, you can take a look at it here. I fell like I'm coming home writing a book about Cocoa related technologies. While hardware has come a long way the underlying philosophy of OSX has not changed since the NeXTStep days. It makes developing fun again (at least for me). Who knows if I'll do more java or not, best gig would be a combo, front end OSX, back end Java EE.

You can see some of the beauty possible with Core Animation on Apple's site or of course you could buy the book and mess with the samples. It has been a fun time and I'm really stoked about the transition.

So way back in the day when I worked at NASA one of the projects I was involved in was the space suits for Reagan's space station. That was supposed to be assembled from K'enx type things and they needed new suits to give the astronauts more time in space (among other things). Anyway as part of that work I got to go flying in what is affectionately known at NASA as the Vomit Comet.

Anyway I noticed that Virgin Galactic announced their space ship today.

At a cost of about $200,000 USD for 4 minutes of Zero-G (or around $830/second) it reminded me of the good ol' Vomit Comet. Which also reminded me of Zero G Corp. While its not orbital its a bit more cost effective at around $4000 (with 7 to 8 minutes of zero g or around $8.30/second). So while the Virgin Galactic flight might be cool, for the working class there is always Zero G Corp.

Alfreso is a fantastic ECM solution that has some amazing features and some great momentum. It has been more than a year since I've used Alfresco and man have they gotten some cool stuff done.

I spent the last couple of days getting certified to teach a couple of Aflresco's classes. I used my mac (running leopard) and I figured I'd post a bit about what I did to get all the features up and running. Alfresco is able to use OpenOffice and Image Magick to do some cool stuff like transform any word doc to PDF or and GIF to PNG etc. Problem is the Alfresco site is short on detail about how to make all that goodness work on the mac.

Being the stubborn guy that I am I would not leave well enough alone and run it on some other OS. It took me a couple of hours but I got everything working. Here are the details...

Grab Open Office from here. I got the aqua interface cause I don't really care about the UI anyway. Install by copying it to your Applications folder. I renamed the app to OpenOffice.app (got rid of spaces) although I'm not sure that is necessary it ended up that way after all the experimentation and I've not had a chance to go back and check if it would work with a space (seemed at the time like something that Alfresco was using was not properly escaping spaces).

Now that you have the OO install done its time to teach Alfresco about it. In your alfresco install (the one that includes tomcat) there is an extensions folder (tomcat/shared/classes/alfresco/extension). Go there and add a folder called 'bootstrap'. Then in there create an XML file called openoffice-startup-context.xml. I've included mine here so you don't have to set it up from scratch. Basically this file tells Alfresco how to startup openoffice in headless mode so that it can be used to do doc transforms.

Install Image Magick with mac ports via a command line that looks basically like this sudo port install ImageMagick. If you are stubborn and you don't want to use Mac Ports the Image Magick community has a binary distro for you here. I used the mac ports build instead of the binary distro so your millage might vary if you use the binary.

That is it, now when you restart Alfresco it will be able to do the document conversion and image conversion. If you are looking for an ECM take a look, its really cool stuff.
