Installing Umap

Well, I needed to install umap and found instrucrion on the readthedocs not being enough for Debian so here’s some notes First thing Install all required packages listed in their readthedocs Install libpq-dev,python3-dev and build-essentials which are needed during umap pip installation Create the virtualenv and upgrade pip with pip install --upgrade pip (this is needed as Pillow requires zlib and libjpeg, pip will take care of this) Install umap via pip using last annotated tag pip install git+https://github.

Ansible, a quickstart

So I have to learn Ansible, cool

Simple steps

  • Install it on local machine, on arch yaourt -S ansible – on the server nothing is needed but openssh and python2
  • Make sure your remote server(s) has/ve openssh running and configured with your pubkey in the authorized_keys file
  • Create an inventory file in /etc/ansible/hosts ( a list of hosts both dns names and IPs are allowed) and make sure in ansible.cfg everything is “nice”
  • Check if it works issuing
  •  Now cry learning playbooks
  • Just kidding, just complex, once in the mood it’s easy
