Containers are a convenient way of isolating applications from the operating system without having to support the overhead of one or more virtual machines.
A container is like a “slimmed down” version of a virtual machine, in that it contains only enough binaries to support the application(s) that you want to run.
Manuel showed us how to build and manage and publish your own container using buildah.
Topic: Repositories
Presenter: Manuel (with help from David and others)
Manuel highlighted the different repository managers for several distributions. The purpose of repositories was discussed. In a small demonstration he walked us through managing the sources and lists that make these repositories work.
During the demonstration of apt, Manuel showed how to install a package and the different ways of removing or purging packages. He added a separate repository and showed how to manage the keys as well as installing software from that repository.
Topic: Jupyter notebook
Presenter: Josemar
Josemar showed us the wonders and marvels of Jupyter notebook, an open-source, interactive and extensible data science and scientific computing tool.
This month we had a bit of a round table to think of some ideas of what to talk about in future meetings.
Some of the ideas include:
> Repository management
> Hardware issues: tools and utilities for managing devices
> Security: SSH, GPG, securing your home network, using networked/wireless cameras
> Network: setup, vlans, remote desktops/admin
> Other: how to build a container, user’s personal projects, desktop customization
David showed us how to set up a NextCloud instance. Nextcloud is your own personal cloud offering a myriad of features and functions. You want to setup your own, private iCloud? Nextcloud makes sure your data never leaves your control. You want to be able to edit office documents on in the cloud? Nextcloud offers a full fledged office solution. You want to synchronize your phone’s data with your Nextcloud instance? Install the iPhone or Android app, connect to your server and you are good to go.

We had a fairly lengthy group discussion regarding a variety of Linux security issues – security management and server configuration, firewalls, pfsense, routers, VPNs, etc. We touched on honeypots, log files, DNS leaks, malware, passwords, 2FA, and many other things. It was good to see some new faces!

A new year and the ELUG is still strong on their VIM journey. This month, Rajiv presented some of the really, really advance features that VIM offers. If you want to see for yourself, there is a video about that available here.
This month we had a round table social talk. Everyone was encouraged to bring an idea to share, or just something about what’s going on in their Linux world. It was good to see some new faces!
Manuel walked through how to setup a simple RAID system using mdadm.
