Dropbox is great product, I use it on Windows, Linux, Mac Os and iPhone. But on the Windows version (version 0.7.110), there has been a bug for more than a year now. Dropbox seems to consume “something” in Windows that cannot be allocated anymore. The bug appears on Windows XP, Vista, 7 32 and 64 bits.

When it appears, a lot of programs crash, they cannot show any kind of windows, menu or any windows user interface, the only way to save you from rebooting is to quit some programs to be able to launch the task manager and then kill dropbox and restart it again.

I have to say I never shutdown my computer, so it might only happen on computers running for days.

Hooks on the SVN Server
You might not know this but you can add a lot of personalized actions on your repository. You just have to add script files to the “hooks” directory of your repository. For a complete list of hooks file name, look here.
The two most important files you should consider adding are :

• post-commit : This file is executed each time something is commited. With it you can send the change made during the last commit.
• pre-revprop-change : This file controls what property you allow to change on your published files. It’s really useful when you want to allow people to edit some already committed logs.

Useful SVN properties on files and directories
SVN properties can be attached to files and directory to define special behaviors on the other clients or on the server. For a complete list of the SVN properties, look here. Here are for me the most important SVN properties :

• svn:externals : Reference to an external SVN source. This is very useful, you can have the same files copied.
• svn:needs-lock : This will force you to lock file(s) before committing them. This should be only use for special files like binary file that can’t be merged (Word can merge concurrent versions of the same file).

Quick note : A very bad idea I had was to put my SVN files within my dropbox folder. It creates a lot more locks than SVN normally does.
