Whenever I see

dd if=this of=that

I usually prefer to

ddrescue this that

(usually --force is required to write to a partition)

Not only it displays many more information than dd's default and it doesn't require blocksize tinkering, but is also capable of resuming and recovering from errors.

Currently reading "Performance Analysis and Tuning on Modern CPUs" by Denis Bakhvalov and liking it very much.

Tails natively ships with a #XMPP client. Currently Pidgin.
For security reason Tails is going to replace it.

New XMPP client that Tails is likely to natively install will be either @dino or @gajim

Some research about them and Tails requirements you can read here:
gitlab.tails.boum.org/tails/bl
(keep in mind that it's a living paper)
