The Duct Tape Programmer - Joel on Software
This is absolutely right (and funny). I would like to copy some good extracts here but there are so many, I would have to copy the entire article.
Google Web Toolkit Blog: Delivering faster, richer GWT applications to your users
GWT is ready to use the webkit inside IE, provided by the Google Chrome Frame plugin. I wonder if our corporate clients with the strict policy on software they use, are willing to install the plugin...

Really funny HOWTO make yourself indispensable by writing code that noone wants to maintain. Of course, dds is obviously joking.

Aza’s Thoughts » You Can’t Multitask
"The net effect is that it takes more time to multitask a set of actions than it does to do them sequentially."

Applications meme
I usually don't take part in these kind of meme games (actually I have never) but this time I thought I could make an exception. Not that this meme is less silly or less absolutely useless than others but for some strange and unexplained reason I found it interesting to try and answer those questions about software I use. So here it is:
1. Which desktop manager do you use more often ?
I use Gnome just because it is the default in Ubuntu and experience has taught me to keep the defaults otherwise trouble is lurking in the shadows.
2. Which desktop application you would not like to see implemented again on linux? And why?
Normally, I wouldn't answer this one because I couldn't care less. At the very last moment though I remembered how annoying it is to have 4 or 5 different media players on my linux machine, each one designated to play a certain type of files. Plz don't create another one. Instead try to make one of the existing ones play everything.
3. Which desktop application you definitely would like to see implemented on linux? Describe it briefly or point out to a similar application.
A decent application for synchronizing my mobile device (phone or other) with evolution or the google calendar.
4. Write the name of the last project (not the very best, the last!) that made you wish to thank their developers so you can thank them now!
The scrobble function in MediaPortal :-) I know it 's a windows application but the question doesn't say it has to be linux.
5. (Optional) Link the blogs of 1-3 people you’d like to take part to this meme. (no more than three). you can skip this question if you like.
What? You mean the others were mandatory?

The case of the WrongClassException
Yesterday, one client reported a strange bug in his application. It was an org.hibernate.WrongClassException during loading of some pojos from the database. I should mention here that the application is EJB3-JPA based with SmartGWT for the front-end. The exception was thrown when trying to load a specific object of class A and hibernate reported that the object was already loaded in the session but it was of the wrong class (class B). After playing around the database and the pojos annotations I saw that the two classes were subclasses of a common class and that the @Inheritance(strategy=InheritanceType.TABLE_PER_CLASS) annotation has been used on the parent, meaning that the two subclasses were mapped onto separate tables. I luckily remembered that in that case the primary keys have to be unique among the two tables even though we are talking about separate tables, otherwise hibernate will get confused when an object from table A is already loaded and it tries to load an object from table B with the same id. It thinks that the object is already loaded but it is of the wrong class. The odd thing in my case was that the two tables actually had different keys!!! What had happened as I discovered later was that the client had added some lines in one of the tables without caring about the key uniqueness between the two tables, thus leading to the WrongClassException problem.
Conclusion: Never allow the client touching the database!!!

FireStatus 1.5 meets Del.icio.us
FireStatus 1.5 is out and it supports saving bookmarks on delicious. If you select the delicious checkbox a second text line will appear to enter tags for the bookmark. You don't have to select the "include url" checkbox for delicious unless you want to send an update to the other supported services. Delicious support also includes receiving bookmarks from your friends on del.icio.us in the usual way with popup notifications.
In the preferences, you have to give your delicious credentials and set the interval for polling for bookmarks from your friends. Be careful not to set interval to less than 30 minutes because you risk being temporarily throttled by the service.
The future
The next feature to be implemented is a list of all updates received from all enabled networks. Popup notifications are popular but if you miss one there is no way to see it, so the plan is to have a list (a sidebar maybe) with the past notifications (maybe the last 50?).
After that the most ambitious feature will be to create a post in your blog with your daily activity on the firestatus supported networks. Blogger will be the first to be supported (I use blogger. That 's why :-))
