• Install both xscreensaver and xsecurelock using your package manager

• Make sure xscreensaver is not set to lock the screen or to manage the display. Xfce aleady does all those, so there is no need to enable it again.

• Also make sure that the xscreensaver daemon is not autostarted. Not doing this may result in the screen not being locked.

• Set the following environmental variables (in ~/.xprofile or ~/.xsession) for xsecurelock:

  # xsecurelock options
  

export XSECURELOCK_SAVER=saver_xscreensaver

Clearing old applications from xfce exo

In order to find out where exo reads desktop applications from, I had to run the application from my terminal using the command:

strace exo-preferred-applications 2>&1 | grep 'openat.*\.desktop'

This allowed me to identify two folders where exo reads preferred applications from:

import crypto from 'crypto';
import assert from 'assert';

const header = {"alg":"HS256","typ":"JWT"};
const payload = {"loggedInAs":"admin","iat":1422779638};

const unsignedToken = Buffer.from(JSON.stringify(header)).toString('base64') + 
'.' + Buffer.from(JSON.stringify(payload)).toString('base64');

const hmac = crypto.createHmac('sha256', 'secretkey');

The following is a function I use in my .zshrc file to achieve some form of lazy evaluation.

local function lazy_load() {
    local -xr thunk="$(cat)"
    # (u) removes duplicates
    local -xr triggers=(${(u)@})
    
    # Only if length of triggers is greater than zero
 # otherwise the function will immediately execute.
