Fighting Dell!

Ok - so I've been having trouble with my Dell Latitude e5410. What kind of trouble, you ask? Well, I discovered it when listening in on my favorite tunes on Spotify. Intermittent there was a "buzzing" sound for a brief moment, like if my headphones weren't properly attached, or poorly fitted into the jack.

This happened 5-10 times per song and was really annoying me, but I couldn't really figure out what it was. Tried a couple of things, like testing with different headphones, downloading new audio drivers, but it never when away. It even occurred when listening without headphones. And no matter if it was streaming media or music on from my local library.

So I gave up. Sigh! Stopped listening on music while working, that is.

Half a year later, and some hours to kill, I started searching for a solution (again). But how do you Google it? "Dell sound noise"? "Dell e5410 audio buzz"? No luck.

Turned out the magic word was "music", as this issue is most annoying when listening on favorite music, it seems. I finally found this thread, which didn't specifically mention the e5410. It eventually led me to try to upgrade the Intel Storage Controller provided by their Rapid Storage Technology anyway. Simply downloaded the driver from Intel and installed it.

Problem solved. Thanks to a dedicated community. Really - big thank you! Wish Dell was monitoring their own community and supplied hot fixes to issues like these. The driver download section isn't very helpful, even with your computer's identity tag supplied...

GWT and Spring Security

Update! - Based on the post below, and my other post regarding Spring Security and OpenID, I have added Open-ID support to the sample application below. For those interested, here's the write-up of changes. I've spent quite some time digging into ways of integrating GWT and Spring Security. It all started by reading the following post in the GWT Forum - Best practices/ideas for GWT with Spring Security (or equivalent) , and then checking out this blog - GWT and Spring Security . To make matters worse, I started reading Security for GWT Applications and specifically about the "Cross-Site Request Forging"-attacks. Now, what could I do about it? Well, starting by setting up my own project (Maven-based) with all updated dependencies (GWT 2.0.3 etc) and started reading the Spring Security Reference Documentation (puh!). Instead of See Wah Cheng's approach of implementing a custom authentication service, I decided to rely on standard namespace configuration

Using Spring Security's OpenID implementation (openid4java) on Google App Engine

The goal with this exercise is to have a running example of an OpenID login on a simple Spring application, using Google as the OpenID Provider. Note that the application will be running on Google App Engine and that Spring Roo is only used for simplicity of creating the project files. Any Spring-based application could use the same implementation. First of all, create a simple project using Spring Roo (or any equivalent framework), including the default security setup: project --topLevelPackage com.technowobble persistence setup --provider DATANUCLEUS --database GOOGLE_APP_ENGINE entity --class ~.domain.MyEntity field string --fieldName name controller all --package com.technowobble.controller security setup This setup only provides us with a form-login, which is not what we wanted. So what about OpenID? Well, if it wasn't for Google App Engine, I would happily have added an <openid-login>-tag to applicationContext-security.xml, but things are never that easy, are the

Adding a custom GWT module in a Roo-project

So I started looking into Roo the other day. Seems like a nice tool (once it matures a little more). Anyway - I wanted to create a custom module in addition to the two being generated when adding GWT-support to the project. Not as easy as I thought, mainly because I hadn't seen the Url Rewrite Filter before. I ended up with a 404, no matter what I did, and couldn't figure out why. Frustration! After reading up on the url rewrite stuff, I was ready to give it another try. Let's create a module called Application, based on the standard sample application you'll get using the GWT wizard in Eclipse. First of all, create the Roo project using the following instructions: project --topLevelPackage com.technowobble persistence setup --provider HIBERNATE --database HYPERSONIC_IN_MEMORY entity --class com.technowobble.domain.MyEntity gwt setup (The "gwt setup" setup command generates some code that will not compile unless there's a persistence setup and at lea
