cocotron.org facelift

I recently switched cocotron.org over to a new site I have been chipping away at. There were a few things I knew I needed to do, page generation using a better template system which would help with content organization and fix a big annoyance with the examples.

The original site was done using server side includes with a simple header&footer template. If you've used SSI's you know how extremely limited they are, especially in the older version of Apache my hosting provider is using. I'm sure some people have done amazing stuff with just SSI's, but that is not me. I decided to write a CGI program to generate pages using Foundation on OS X and then get it working on the Linux shared hosting account where cocotron.org lives. One bug fix later in Cocotron it was generating pages on the Linux account. Most of the work was reorganizing the html of the old content, coming up with the new layout and updating some content.

One recurring problem with the examples and building apps in general is that the DLL's and framework resources need to be copied into the same directory as the .EXE in order to run the program. The documentation does describe this, but automating it during the build process would make it all a lot easier. So there is a new program in CDT which fixes this problem called retargetBundle, it does a fast copy, using modification dates, to copy the DLL's and resources as the final build stage. If you have the latest CDT and build an example, it should be ready to run.

Satisfied for now with the page generator I'll be updating the content more regularly and probably work on some new dynamic aspects of the site. This will improve the site and increase the use and testing of Cocotron on Linux.

Radial CGShading fun

While there is a bunch of other work going on in Cocotron, some of the results are more visually satisfying than others. One recent addition is radial shading. Here is an updated CGShading example running on Vista, showing off some of the themeing work too.



The CGShadingCreate example runs on Windows and Mac.



Whoops! Well, it works on the Mac most of the time (10.4.10 on a MBP).

(this is a bug in OS X)

Best personal checks yet

For most of my checkwriting life I have used the plain old bank issued "security" check, it is only recently, under the influence of my wife, have I slowly moved into the world of custom checks. Every year or so I spend far too much time browsing pictures of bunnies, licensed characters, ye olde script and just generally bad art looking for something that remotely feels like a fit.

While recently repeating this ritual my wife pointed out a check printing site that allows you to use your own image on the check and then commented "You could use images from that site of yours", brilliant.

I chose the four rotating images series:

(As a special treat to my faithful readers, the third image is a yet unpublished view of the Cocotron laboratories)






I ordered these at uniquechecks.com. The site expects a 6"x2.75" image, minimum 432x198 (72dpi) and the images should be only a few hundred k or you'll have trouble uploading. I used 288dpi high quality jpg's and am completely happy with the results.

Yet another CGShading example ...

but this one runs on Windows too :)

The Cocotron now supports axial gradients via a CGShading & CGFunction API, works on Win2k and above.

Cocotron article over at NewsForge

I had the opportunity to chat with Nathan Willis of Linux.com about Cocotron, the result is this article:

Newly released Cocotron lets developers code Mac APIs under Windows

Overall I am pleased with the result. One small correction, I said I would recommend Cocotron if you were a Mac developer looking to get on Windows, not GS. I did say GS is the way to go if you are looking to get on Linux.

I can't believe he actually linked to the Cocotron blog :)
