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.

Today is #changeyourpasswordday, a gentle reminder that if you (have to) use this policy, it's trash. Users will tend to make serial passwords like password1, password2 etc. which is overall less secure than an actually strong password used over a (very) long time.

Tails

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:

We're *really* excited to announce the sponsorship of end-to-end encrypted group chats (OMEMO) in Siskin, the #ios #xmpp client! One step closer to an excellent XMPP experience on Apple devices :)

This is very handy for copying wrapped lines of text in tmux-style even if you are not using tmux.
