jQuery BlockUI Plugin

The jQuery BlockUI Plugin lets you simulate synchronous behavior when using AJAX, without locking the browser[1]. When activated, it will prevent user activity with the page (or part of the page) until it is deactivated. BlockUI adds elements to the DOM to give it both the appearance and behavior of blocking user interaction.

Freebies Round-Up: Icons, Buttons and Templates | Graphics

Visual design elements can considerably improve the readability of the page. Using them, you can make it easier for your users to scan the presented content and find the information they’re actually looking for. Icons can draw reader’s attention to the key aspects of the article and visualize the topic of the post. Buttons can be used to motivate users to some particular actions; and templates are supposed to help designers to create user-friendly interface elements right away. And whatever aim you’d like to achieve, free visual design elements are always useful - simply because they can give your text content a better visual appearance.

We’ve selected fresh high quality icons, buttons, vector graphics, templates and layouts. You might know some of them, but hopefully not all of them.

Not all listed freebies can be used for commercial projects, however you can use all of them in your private projects of for you personal purposes. Please read the disclaimers carefully before using icons - they’re changing from time to time.

GrailsPlugins/AuthPlugin

This is a Auth Plugin based on Spring Acegi Framework.

This plugin extends the acegi framework and provids a simplified access control model, that means developer can use this plugin as a drop-in user/security module for grails powered project without knowing the details of acegi framework.

Heterogeneous database replication with SyncML

Availability and performance are primary considerations when you’re developing distributed applications. But using data stores to address these concerns can result in problems with data synchronization between heterogeneous data stores. In this article, Jayanthi Suryanarayana and Neil Tunnicliffe offer a solution using JDBC and the SyncML standard to achieve generic database data replication.

When you are designing distributed applications, you must consider availability and performance. A common solution is to include a data store on the client system. Typically, the client will require a lightweight data store as a result of limited resources. This approach poses a challenge for data synchronization between heterogeneous data stores. One resolution to this problem is a Java-based approach using JDBC and SyncML standards for heterogeneous database replication, but first a little background.

Create a Lightbox effect only with CSS - no javascript needed at Emanuele Feronato

You may call it Lightbox, or Greybox, or Thickbox, but it’s always the same effect.

When you are on a page, and click on a photo or trig some event, a Lightbox is an effect that fades the pagein the background to show you new content in the foreground.

I mean this effect

Checking Projects into SVN - Grails - Confluence

Up to and including Grails 0.4.x there are files that are generated or copied by Grails within your project tree. This can be problematic as it is unclear what is to go into SVN and what isn’t. In addition, you will not usually want your compiled .class files going into version control, nor duplicates of your libs etc.

This is correct at the time of writing (Grails 0.4.x) but makes the following assumptions:

* You do not want ./plugins/core (Core Grails plugins) under SVN
* You do not want anything under ./web-app/WEB-INF/ under SVN. You should not usually need to put files in here. Files from ./conf are copied to WEB-INF/classes so they are on the classpath, if you need to supply anything.

Why is this such a hassle? Well SVN prevents files or directories being considered for version control by checking an “ignores” list that is set via an SVN property. This property is set on specific directories within your SVN working copy. Therein lies the problem - until you have a working copy you cannot tell it to ignore files.

Grails - GrowlGrails

Growl is a generic but slick notification framework for OS X. This script bundle adds configurable notifications for common grails script events, so that for example you can have it automatically pop up a message when your “grails run-app” has completed, or an error has occurred while running a grails command.

Jamp! Easy Java/Apache/PHP/MySQL install in one click | Alex @ Net

Counting times I have installed Java, Apache, PHP, MySQL, etc, changed configuration, setup additional modules and so on, I decided to summarize my knowledge in this area and help myself and others to save our time. I created the installer, which primary goal is to provide the developer with command-line tools for basic Apache/PHP/MySQL management tasks. The second reincarnation of this tool-set was in a form of several JScript script files.

This a preview version of AMP installer and configurator. Although, it is very far from being a real time-proven and tested installation method, with your help and effort we can make it better.

Developer Notes: Using google’s free SVN repository with Eclipse

Ok - here are some very quick notes on getting a google svn hosting account set up with eclipse; as google is offering us all such an amazing resource, I have a feeling I’ll be doing this again some time whilst working on other projects…

Making An Operating System Faster

The performance of computer hardware typically increases monotonically with time. Even if the same could be said of software, the rate at which software performance improves is usually very slow compared to that of hardware. In fact, many might opine that there is plenty of software whose performance has deteriorated consistently with time. Moreover, it is rather difficult to establish an objective performance metric for software as complex as an operating system: a “faster OS” is a very subjective, context dependent phrase.

An operating system’s architecture has a much greater longevity than that of common hardware. Operating system researchers do not come up with new, much faster algorithms as consistently or frequently as hardware updates happen. Nevertheless, those involved in “producing” operating systems — researchers, designers, implementers, and even marketeers — have the arduous task of ensuring that the associated performance curves keep going up. There are not many viable players in the OS market (some might argue, even if rhetorically, that essentially there’s only one). Still, it is a very tough market, and OS vendors must “improve” their systems incessantly.
