Home Made CNC Resources
There are hundreds of excellent resources out there that will help you build your own CNC machine. Listed here are some that I found useful. I will include other resources as I find them and by recommendation. This isn't a list for every company that sells a part that might be useful though, these are select resources that really help home CNC enthusiasts (and particularly those in the UK when it comes to parts).
Dynamic Dashboard with PrimeFaces - Part 2
After putting together the first page on writing a dynamic dashboard with primefaces I descovered that the method I had come up with wasn't as good as it could have been. Most noteably it didn't work properly when the dashboard was updated via a partial page refresh. Typically that type of update would result in a non-unique ID exception being thrown when the page was rendered.
Dynamic Dashboard with PrimeFaces
I do a fair bit of work with the PrimeFaces JSF library and it is, IMHO, the best set of JSF widgets currently available. PrimeFaces has an excellent demonstration site as well which gives examples of the most common usage patterns of each widget available. Occasionally though it's necessary to stray outside what is demonstrated and one such area is with backing beans. In the project I'm currently working on I need to make a dynamic dashboard and this is how I've done it.
Simple CRUD Example - Part 2
In the last article I showed you how to create a Debry database and set up a persistence unit. In this article I'll create a very basic CRUD application. Using JSF 2, JPA 2 and EJB 3.1.
Checkstyle Rule Suppression
I recently started using Sonar to automatically check the quality of the code I write - turns out it's mostly ok with a few systematically bad points that I will work on improving. One of the problems I faced though was what to do about a barrage of false positives from a small number of the default rules that ship with Sonar. Here's how I fixed the problem.
Maven Build Problem with JDK 7
I recently upgraded my system from Java 6 to Java 7. Over all I'm really pleased with the improvement I'm seeing from Java 7 but the upgrade has come with a little cost. For some reason I'm getting a failure in NetBeans when I try to deploy one of the web applications that I'm working on.
Installing Maven on Ubuntu 11.10
For some reason I can't possibly fathom Linux seems to have a downer on all things Java. Packages are available for most things but they are invariably not the latest version which means performing a manual install - not the end of the world but irritating when you can just install a package for most things. This page gives a quick overview of how to install Maven 3 on Ubuntu 11.10 but the same (or a very similar) process will work on most distributions.
