Google Iphone Calendar Selector

I got an IPad a while back, and something was always bothering me with it. It had this really nice looking calendar application that was useless because it only showed one of my 5 google calendars. Turns out Google tought of that. You need to navigate to their Google Iphone

Specifying tests

The latest post on the Google Testing blog is quite interesting. Philip Zembrod discusses the readability of code developed by TDD and found that sometimes reading the test first didn’t always help to understand the written code. He makes a valid point. I started objecting to using mocks when

Testing on Google AppEngine (Python SDK)

Testing in Python and Django is pretty straight forward. However I wanted to write tests that assert email sending, URL fetching and other external sources. Making sure the intended code is executed and allowing me to write fuller tests. These external actions are accessed through Google’s API, and there

Interesting issue on GAE issue list

I was browsing around the issue lists on Google AppEngine, just some midnight light reading before going to bed… I stumbled on the following issue, marked as critical: http://code.google.com/p/googleappengine/issues/detail?id=1970 What’s interesting about it is that this is also what is

Programming for Android

So I’ve done my first programming for Android phones and thought I’d write a blog post about the experience. Programming for Android is a bit different from working with the Compact Framework. The abstraction level for the Dalvik applications is somehow high than the Compact Framework application. One

AppEngine + Grails + Cron

I just added a Cron job to “ping” my application every 1 minute. After a short discussion with Paul Cusch, whom commented on one of my previous posts regarding the load request issues Grails on AppEngine is seeing. I decided to give it a try. This solution is entirely based

Added precompilation-enabled to AppEngine plugin

In the 1.2.8 version of the AppEngine SDK there is an option to precompile your solution as you deploy it to the AppEngine. Apparently precompilation can save up to 30% runtime on loading requests. I added the option to turn on the precompilation-enabled setting in appengine-web.xml to

Deploying AppEngine SDK 1.2.8 and Grails 1.2.0-RC1 to AppEngine

If you use the app-engine plug-in deploy command using AppEngine SDK version 1.2.8 it will fail with the following error: [java] Bad argument: email requires an argument, for example, "email=FOO" [java] usage: AppCfg [options] [] [java] Action must be one of: [java] help: Print help for

AppEngine startup performance attack plan revealed

Google just announced their attack plan for handling the long startup cost for, among others, Grails applications. Apparently what I can do as a developer is to enable pre-compilation of my application. I’ll experiment with this at the end of the week I hope. Read the full post on

AppEngine SDK 1.2.8 released

As far as I can see there is no mention of startup performance. Doesn’t have to mean they haven’t worked on it. Ill check it out to night to see how the application behaves.

Prerelease of AppEngine SDK 1.2.8

I got this on twitter last night. Google is doing a prerelease of the next AppEngine SDK. Details can be found here: http://groups.google.com/group/google-appengine-java/browse_thread/thread/fe334c9e461026fa Only thing that worries me is that there is no mention of application startup times.

AppEngine enhancer issue

The issue with the AppEngine enhancer still exists with Windows 7. Let’s hope for the next version of Windows then…

Got my Wave invite

A friend of mine invited me to Google Wave just yesterday. The same night Google invited me as well. I’m hoping its just a bonus email and not a wasted invite

AppEngine start up cost

I’m struggling with an issue where Google AppEngine will take over 30 seconds to do the initial loading of my hosted web-application. Now apparently it does take a while to load applications that rely on allot of different jar files. Which mine naturally does. There are however some rumors

Google Appengine SDK 1.2.6

Today they released a new version of the SDK for Google AppEngine. Personally I’m very excited about the ability to recieve email. Here is a link to the Java release notes. The blog post at Google only links to the python release notes. http://code.google.com/p/googleappengine/

Invitation model marketing

The Google Wave beta program rolled out a bunch of Beta invitations lately. I discussed this with a friend, the marketing value of an invitation model for software. GMail started as an invitation, most people I know started using GMail as they were invited by others. I my self started

Google AppEngine and Grails 1.2-M2

I upgraded this morning, figuring that the changes related to the .gsp views and their pre-compiling would reduce the cold start issues I’m having with Google AppEngine. However the 1.2-M2 release of Grails, doesn’t fly on Google AppEngine right now. As far as I can see on

Finding entities with GORM-JPA

I’ve been having this issue for a while. Putting it off, but now I had to get my hands dirty. The findBy… methods weren’t returning any objects even though there were data fitting the specified values. So tonight I finally took the time to take a look at

Sending mail on Google appengine with Grails

Sending emails with Google AppEngine is quite straight forward once you get a hang of things. I ran into some issues, for example I never got the high level api’s to work. The code executed but the emails were never received. Instead I went for Google AppEngines own “low

Google AppEngine does not like leftshift

I ran into an issue last night where Google AppEngine wouldn’t persist my entities. If I create an entity using the parameters provided by Grails; then the Save operations would fail with the following error Uncaught exception from servlet org.codehaus.groovy.runtime.InvokerInvocationException: groovy.lang.MissingMethodException: No signature

Grails and Google AppEngine Beginners Guide

I recently moved one of my applications to Google AppEngine. What I found missing was an explanatory tutorial to get started. As I mostly work with C#, I kept running into issues simply because I wasn’t too familiar with the technologies used. Thus I’m writing this easy to

Rendering lists from Google AppEngine as JSON

I ran into another problem with Google AppEngine. I finally got it to save my entities, only to find it crashing as I wanted to send them back again rendered as JSON. I had a piece of code looking like this: def services = { params.max = Math.min(params.max ? params.

Researching Android Calendar

I’m itching to buy a HTC Hero. However I want to test it out before committing myself to buying one. One feature in particular I want to test is the Calendar application. A good Calendar application is a must for me. I got the idea that I could run

Moving from Mor.ph to Google AppEngine

Moving from Mor.ph AppSpace to Google AppEngine isn’t as easy as I hoped. Installing AppEngine plug in Initially moving the Application by installing the app-engine plug in is straight forward. Except that the command-line written in the plug in page for executing the initial setup is wrong. Ive

Saving entites on Google AppEngine

I ran into a problem with Grails on Google AppEngine. When I was saving my entities it tried to save the wrong type of entity. I ran out of ideas on this one and brought it up on the Grails User mailinglist. I started to work on some reproduction code
