I have a 2008 HP 2133 Mininote PC, which is a small laptop machine. It has a 32-bit VIA C7-M Processor running at 1200 MHz. The memory is 2 GB and the single hard disk is 120 GB.
I originally purchased it with a vendor-installed SUSE distribution. I later installed Ubuntu 12.04 LTS. The machine is now at 14.04.5 LTS. I generally do weekly software updates as provided by Ubuntu.
Over the years, the machine gradually accumulated a lot of old Linux kernels, and it began...

I have two machines running Ubuntu, one a 5-year old Pogo Linux desktop ("Pogo2011" running Ubuntu 16.04 LTS) and the other an 8-year old HP notebook ("HP2008" running Ubuntu 14.04).

It has been my experience that Ubuntu OS upgrades do not generally produce...

I started from the Update Manager, which offers the LTS upgrade once it has been made available three or four months after the initial release in April. I have made it a practice...
I use Emacs to write code occasionally, mostly Fortran. A common thing I need to do is search and replace everywhere in a region confined to a rectangle within the text. An example is altering an existing code from Fortran 77 format to Fortran 90, specifically changing all of the Cs in column one (indicating comments) to !s. In Emacs terminology, this is a rectangle of width 1 character and as high as the number of lines in the code.
I have had difficulty figuring out how to do this...
