  • Speak to me! – Purism

    My trusty laptop’s speakers gave up the ghost. I don’t like to sit around in headphones all the time, I don’t have any other speakers, and the replacements are still being manhandled by the postman. I’d get used to the austerity if I hadn’t started missing calls from a friend. That’s unacceptable! But what am I supposed to do? Buy extra gadgets just to throw them away after a week?

  • LDAP query from Python · Pablo Iranzo Gómez's blog

    Recently, some colleagues commented about validating if users in a Telegram group were or not employees anymore, so that the process could be automated without having to chase down the users that left the company. One of the fields that can be configured by each user, is the link to other platforms (Github, LinkedIn, Twitter, Telegram, etc), so querying an LDAP server could suffice to get the list of users. First, we need to get some data required, in our case, we do anonymous binding to our LDAP server and the field to search for containing the ‘other platform’ links.
