littles3 version 2.3.0 released

Saturday, February 14th, 2009

Version 2.3.0 of “littles3” has been released. This release includes enhanced serialization of business objects to support non-serializable commons logging logger implementations

Issues included in this release:

Code reviews in Google Code

Wednesday, December 3rd, 2008

So I just released a new version of “littles3“, a project hosted at Google Code. I tried out the “Issue” feature; pretty neat. But what I really found cool was the “code review” features in the source code management. For instance, the source file that was changed in my latest release was to FileS3ObjectDao. I was able to have a diff from r21 (the old version) and r37 (the new version). It even let me comment right within the diff, in either the old or new version.

littles3 version 2.2.0 released

Tuesday, December 2nd, 2008

Version 2.2.0 of “littles3” has been released. This release improves performance of listing keys within a bucket. For instance, 1000 keys with version 2.10 took 3.36 minutes. With version 2.2.0, this same list of 1000 keys took 1.75 seconds.

Issues included in this release:

littleS3 basic usage

Friday, November 28th, 2008

I have updated the littleS3Getting Started” wiki page, adding a “Basic Usage” section. This section includes:

Some littleS3 documentation!

Wednesday, November 26th, 2008

So, I promised some documentation “soon” for littleS3. That was 2 months ago. Well, I have finally made good. I have just published a “Getting Started” wiki page to the project site. So far, this document provides some background on the project components, how to deploy it to an application server, and what the configuration files “configure” (along with sample configuration files in the project download section).

I would still like to add some samples of how to use the system to create buckets, add objects, etc. This is very similar to the usage described in the Amazon S3 Developer Guide for the REST API, but there is a bit of a trick since you are using your own application server. In addition to the host name, you may need to include a context path (a servlet notion) to the REST URIs.

I found Simon Willison’s Javascript timer to be totally awesome. The app is written in Javascript, all on one page. It lets you specify a time, and then a big-font timer counts down. The timer takes up the whole page. It can give you a warning, the background turns pink, when the timer is almost up. When the timer reaches zero, the background turns red and 0:00 blinks. Take a look at the page source for documentation on how to use He says that he needed something for a Lightning Talk and this is the result.

Looking at the code (like I said, the Javascript is all in the page source, so just “view source” in your browser), it is a really cool example of Javascript. I was amazed how simple and elegant Simon’s code was. As someone who definitely is a poor Javascript hack, it is nice to see some good Javascript. And, I can use it as a tea timer too! 🙂

Greasemonkey for Pearson Access

Wednesday, November 12th, 2008

During the day, I professionally work on a web application called Pearson Access. Today we determined that we needed a user administration process for one of our Pearson Access customers that would require them to always select a certain user role when creating a new user. The system doesn’t auto-check the role, the user will need to be trained to check it.

But, being a geek, that got me thinking. What if Greasemonkey could be used with a Greasemonkey script in Firefox to automatically check a role when creating a new user account. So, I wrote such a script: autoselectrole.user.js.

littles3 version 2.1.0 released

Tuesday, September 30th, 2008

Version 2.1.0 of “littles3” has been released. The only component change in 2.1.0 is the littleS3-2.1.0.war. This version enhances the web application configuration. The “host” value can now include a token “$resolvedLocalHost$“. Example:


The token “$resolvedLocalHost$” will be replaced the value of InetAddress.getLocalHost().getCanonicalHostName(). This may be handy if your application server isn’t bound to “localhost“.

littles3 version 2.0.0 released

Thursday, September 25th, 2008

Version 2.0.0 of “littles3” has been released. This release restructures the project into modules: API, file system data module, and webapp. The file system module also includes support for metadata. Unfortunately, there isn’t any more documentation than before. So to get the system working, you would have to wade through the source code. But I will hopefully get some documentation created soon. 🙂

Hello, Android

Sunday, July 13th, 2008

So, July 11, 2008, came and went. What happened on July 11? The iPhone 3G came out.

But I don’t have an iPhone. The other big thing is that the Apple iPhone App Store opened. But I don’t have a Mac, so I can’t run the emulator or create my own apps for the emulator.

So, I celebrated by creating my first Android app.

Hello, Android

This is the “Hello, World” version of an Android app running in the emulator. It was very easy to make. What made it easier for me is that Android apps are written in Java. (I am a Java developer by day.) The “Getting Started” tutorial even shows you how to use Eclipse.

I have only created the sample app so far, but it looks pretty easy for a Java developer to write an “Activity“. But, of coarse, the apps currently can only run in the emulator. But the emulator can be integrated very easily into Eclipse.

Though, it is not like having real hardware like the Apple iPhone. 🙂
