Adding PGP key for your repo Debian/Ubuntu

gpg --keyserver pgpkeys.mit.edu --recv-key insert_key_here
gpg -a --export insert_key_here | sudo apt-key add -

UPDATE:
another solution:

#!/bin/bash

KEYID="$1"

echo "Registering APT key $1..."
gpg --keyserver pgp.mit.edu --recv-keys "$KEYID"
gpg --export --armor "$KEYID" | apt-key add -

Source: https://wiki.hackzine.org/sysadmin/debian-register-apt-repo-key.html

ANOTHER UPDATE:
above didnt work with error message:

gpg: keyserver receive failed: No keyserver available

gpg: WARNING: nothing exported

gpg: no valid OpenPGP data found.

so another try:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 04EE7237B7D453EC

which eventually worked

Not sure what happened as the first command used to work for me in the past.

How to replace in google spreadsheet any character with carriage return

Solution shamelessly copied from https://stackoverflow.com/questions/7528169/find-replace-with-newline-on-google-spreadsheet

IF you are trying to use the Ctrl+F to find and replace well you can't. at least I dont know how.

but if you have a cell say A1 that contains the following : "stack,overflow" then if you type this in A2 it should work: =SUBSTITUTE(A1, ",", char(10))

you can then copy the content of A2 and in A3 right click -> Paste Special... -> Values Only.

[SOLUTION] screen -r : Cannot open your terminal ‘/dev/pts/0′ – please check.

as seen on http://blog.hbcom.info/archives/430

when trying to re-attach screen while sudo-ing you see:
$ screen -r
Cannot open your terminal '/dev/pts/0' - please check.

Solution:
Before starting screen type:
script /dev/null
And after that you can type:
screen -r
Only drawback is that you need to type one additional exit for script to terminate.
