This is an ongoing list, which is more of a “Remember that when…” thing for me.

This took a whole day for me. Hopefully I can save you the pain. I added quite a few possible search terms here for maximum coverage, so the text may get a bit repetitive. I mean – when I tried to look for a solution, I didn’t even know what to look for – so I tried googling for every symptom I saw, to no avail.
The deal was this: my page has a very large …
Double submit is when a user submits a form on your web page twice (well, technically they can do it more than twice, but you can’t call it a double submit…)
It usually happens when your user double-clicks your Submit button instead of clicking it, but may also happen in two other popular scenarios: your buttons do not provide the user with a visual feedback of being clicked (e.g. when you use an image as your …
In one of my projects, I have several customers all served from the same CakePHP application. This is by no means unique, and is a very well understood pattern of maintaining co-exiting websites. In my set up, each of the customers has their own website, with their own data and design, but there is only one copy of the actual application behind all those websites. This is, of course, a fundamental attribute of selling SaaS.
From a …
If you followed part 2 of this tutorial, you have an appengine application that displays a Google map in your browser, and lets you click the map to add markers to it.
While extremely useful on long, cold Winter nights, you probably want more from your application. For example, you’d probably like to be able to save those markers somewhere, so you can share them with your users.
This part of the tutorial will focus on this …
In this part, I’ll show how to get started with STS (SpringSource Tool Suite) and Spring MVC. We’ll only use the default project that STS generates, but it’s a good start to any development effort with Spring MVC you might get into.
STS is the easiest IDE to use when developing Spring, mainly because it bundles together almost everything you need to get started, and knows where to get the rest.
If you don’t have STS installed, …
Google’s appengine is the Google cloud offering. It is highly scalable, and provides a free entry level cloud application platform. However, it is not very trivial to develop for and deploy on.
Google maps API version 3 is the current (June 2011) officially supported version of integrating with Google maps. The API allows you to display and manipulate maps in may ways.

Coding a login screen is pretty simple in Android, and there’s quite extensive documentation on how to do screen development. However, there’s one neat little trick I wanted to use: the ‘next’ and ‘go’ buttons on the soft keyboard. These buttons are actions that let you move automatically from the login text input to the password text input, and then from the password text input, you can ‘click the login button’.
This is documented, but it …
Working on a new project, I had a few chats to people and realized that many developers assume that to work with JAXB you need to have an XML schema.
This is not true. If you have the schema, go ahead and use it, but if you only have the XML files you want to parse, JAXB is perfectly capable of unmarshalling your XML into objects without the schema and the binding.
The only problem is – …
