Using sz to transfer files via an existing SSH connection

If you are using KDE's konsole, it has built-in support for the Zmodem protocol.

I often SSH into remote machines via "hopping" SSH which makes it annoying to copy files back. But installing lrzsz on both my machine and the remote machine, and using konsole allows me to type:

sz file.txt

And konsole will ask me where I want to save it on my local machine. I've heard it works in Tera Term, also.

Adobe Flash 10 on Ubuntu with Chrome

I was trying to use Chromium on Ubuntu 10.04 Lucid Lynx, and Flash was working, but about:plugins revealed that it was version 9 whereas I wanted 10.

It turns out that all I had to do was delete ~/.mozilla/plugins/libflashplayer.so which was left over from long ago. I'd already enabled Adobe Flash 10 in the Ubuntu Software Manager, and once that file was gone, a restart of Chrome let it see the system Flash player.
