A number of the sites that I manage for fun are simply static web pages. The dynamic nature is handled by javascript classes and plugins. This means that I really don’t need or want an application server to serve these sites, but I do want to still use some of the practices that I apply to web application development. Enter webby - it works by combining the contents of a page with a layout to produce HTML....
It is now possible to invalidate objects (files) in AWS CloudFront distributions. Handy when someone, like me, occasionally publishes files with the wrong content type. Here is how I implement this invalidation in python....
For Ivy: <dependency org="com.tomczarniecki" name="spring-stringtemplate" rev="1.5.1" /> For Maven (yeech): <dependency> <groupId>com.tomczarniecki</groupId> <artifactId>spring-stringtemplate</artifactId> <version>1.5.1</version> </dependency> Thank you Sonatype....
I've released a new version of my S3DropBox on GitHub. I've moved the project to GitHub so that I can have all my current active projects in one place. Check it out in its new home at https://github.com/tomcz/s3dropbox. This release uses the AWS java libraries. They are finally good enough for me to stop creating my own wheels and vulcanising my own rubber. As a bonus the S3DropBox creates URLs in virtual hosted format (eg....
Another update to my S3DropBox. Due to popular demand (ahem) I've added a progress bar to track uploads and downloads. You now have something pretty to watch rather than a screenful of dots. Any other requests?...
StringTemplate is a great templating engine. It's powerful, simple and quite opinionated. I've come really appreciate its simple purpose: render data. No assignment, no arbitrary method invocation. It is not Turing-complete and it would make a lousy rules engine. SiteMesh is a web-page layout and decoration framework that is my current "golden hammer" when I need to provide a consistent layout across a java web-application. It seems to fit with the way that I think about web pages a whole lot more than something like Tiles - I really prefer decoration over composition as a means of layout control....
I've released a new version of my S3DropBox. You can now right-click on any file to download it, delete it or create a public link to it. Comments, feedback and bugs are always welcome....
For a while now I've been flying the flag for using a post-redirect-get design pattern when writing web applications. In my opinion the current crop of web frameworks still make it very easy to do the "bad" thing since to do PRG properly you need to think what kind of an interaction you want with users and not cop out saying its technically very difficult in . If you resort to ActiveX controls, popups without navigation bars and/or weird javascript hacks to stop users from clicking refresh or back buttons then perhaps you should have written a better web application....
The Jersey JAX-RS project provides bindings for springframework and google-guice. However I wanted to see what it would take to use PicoContainer as an IoC container within Jersey. Verdict: not much at all. Nicely extensible. To see what I mean please take a look at my jersey-pico project on GitHub. I can now create JAX-RS services in Java or Groovy with a very simple IoC container....
I’ve been trying to get my head around cryptography on the iPhone so that I can create a native iPhone app (iPasskeep) that interoperates with my JPasskeep password keeper application. It has taken a while to get my head around CommonCrypto APIs - how to use them, how not to use them and their limitations. It then took a bit of fiddling to find the right incantations in Java to get an interoperable cryptographic transformation....
