I needed to store my Linux-Ubuntu notes somewhere where I could get at them wherever I was.
Then it came to me. Why not stick them up on a website?
Which I duly did. The only problem was that the host of the website I put them up on then promptly decided to increase its fees. Now, while I am not a complete tight-wad I do object to coughing up dosh for a website that nobody uses except for me.
So I thought about it for a while. Then it came to me Why not stick these Linux-Ubuntu notes up on Chalk-Ridge? After all they may be useful to other nefarious coders/publishers/web designers/ne’er-do-wells as well.
So that is what I have done. If you find them useful great! If not – too bad.
But at least I know where to look for the damn things if I ever need them when I am away from my main computer.
Here’s my notes on mounting a USB drive that for some reason fails to mount automatically on Ubuntu.
This would be the case if you plugged in the usb stick and it has not appeared in the “places” tag in the menu bar.
Open a terminal. If you are running in the Gnome GUI you can do this with crtl-alt-t but use whatever method you like.

All this is done through a terminal. Open one from the Gnome GUI with:
Ctrl-Alt-t

Open a console with ctrl-alt-t

I assume the machine is running a gnome desktop manager.
Open a terminal with ctrl-alt-t or do whatever you need to open a terminal.

Last post (here) I showed how to change the format of video files from (say) mp4 to (say) mpg. That’s all fine for converting files. But what if you want to crush down your mp4 or mpg file and make it smaller?
Continue readingHere are my notes on how to convert video files between mp4 and other file types on Ubuntu. Especially between mp4 and mpg but avi and wmv can be used too.
There are a number of GUI converters in Linux but I’ve always found the command line converters the best. In fact most of the GUI solutions are just front ends on these command line driven converters. GUI tool winff isn’t bad but using command line tools (either avconf and ffmpeg) give you more options.

Sometimes when Ubuntu comes out of suspend or even after booting from power-on the wifi connection disappears. Usually the little triangular wedge on the task bar is empty. Usually this is easy to fix.
