My favourite cloud syncing app Dropbox has a nifty LAN syncing feature, which detects when two computers are on the same local network and transfers files directly between them, instead of taking the scenic route via your internet connection.
Unfortunately, this does not always seem to work. In my home setup, I have my Windows 7 box connected to the router via ethernet, while my Ubuntu 11.04 laptop connects via wifi. In this setting, LAN syncing did not seem to work. I "fixed" this problem by connecting my laptop via ethernet and deactivating wifi. Clearly not ideal, but at least I can sync my 2.5gig Dropbox folder without downloading my files at 0.1kb/sec from the Dropbox servers.

August Presentation Clicker LP107T and Ubuntu
A while ago, I bought a wireless presenter from a company called August at amazon. Upon arrival, I found that it didn't work with my laptop running Ubuntu 11.04. I was a bit surprised to find this, since the device basically pretends to be a USB keyboard, and hence should run out of the box on any operating system.
A short search led me to this bug report which explains that the linux kernel patch 2.6.37 inadvertently breaks support for the presentation clicker by adding support for the (rather bizarre) Yurex leg shaking sensor. The two gadgets share the same device ID. Since by default Ubuntu let's you choose from a list of recent kernel versions during startup, a simple fix is to choose a pre-2.6.37 kernel version or update your system in case the problem has been fixed in the meantime.

Bison crashing with memory error:
"bison: double free or corruption (!prev): ..."
After a Ubuntu upgrade I had bison constantly crashing with the following error message:
This blog post provided a solution. Simply type the following on the terminal:
I would also suggest:
*** glibc detected *** bison: double free or corruption (!prev): 0x0000000000e139c0 ***
This blog post provided a solution. Simply type the following on the terminal:
sudo apt-get install bisonIt seems that I accidentally had the bison++ package installed instead of bison.
I would also suggest:
sudo apt-get install flexSince I was missing that package as well.
