Scenario: you are using a remote host as a virtualization host with libvirt and you want to manage it via ”Virtual machine manager” (virt-manager) over SSH. But SSH is listening on a non-standard port, and virt-manager does not offer you to connect to a remote libvirt instance on a non-standard port.

Automatically update your Docker base images with watchtower

I’m an avid user of Docker containers, using base images pulled from the public registry DockedHub. As you may know, Docker containers are based on Docked base images, e.g. I run postgres containers that are based on Postgres base image. It occurs that base images could get updated by their respective author (in our case Postgres team) and pushed to DockerHub. … Continue reading Automatically update your Docker base images with watchtower

Incubo PuntoCom Shop: NON acquistate su questo sito!

Recentemente ho acquistato un iPhone 8 sul sito PuntoCom Shop (linkato in nofollow). Dopo una settimana dall’acquisto, il telefono ha presentato un difetto con la fotocamera, scattando foto con un alone rosa; il difetto è conosciuto da Apple, tant’è che non sono l’unico ad essere stato vittima di questo difetto hardware Apple.

Docker and containerd on openSUSE: reaching the limit for cgroup (and how to overcome it!)

I recently encountered a limitation during an experiment I was conducting; after some trial and error, I recognized that the limitation was due to cgroups. But let’s start from the beginning. I open sourced docker-salt, a small pet project I had in mind in order to have a full blown setup for SaltStack: a master … Continue reading Docker and containerd on openSUSE: reaching the limit for cgroup (and how to overcome it!)

OpenSUSE Leap 42.2: this is how I work (my setup)

Motivation I switched my distribution of choice to OpenSUSE. There are a lot of motivations behind this choice: I wanted an enterprise-grade quality of software in terms of stability, package choice, and supportability Growing interest in software non-distribution specific and/or customized, e.g. Gnome Dogfooding After nearly one year of usage, I can say that I … Continue reading OpenSUSE Leap 42.2: this is how I work (my setup)

Situation: one (or more) remote-tracked git branches got deleted (either locally or remote).

OpenVPN with multiple configurations (TCP/UDP) on the same host (with systemd)

As much more people are getting worried about their online privacy (including me), I started to use a server as a VPN termination (with OpenVPN) when I need to access the Internet via non-secure wired or wireless networks (e.g., hotel wireless network, airport Wi-Fi, etc.). Some overzealous network admins, though, try to lock down the … Continue reading OpenVPN with multiple configurations (TCP/UDP) on the same host (with systemd)

Spotify puzzles: round two

Some months ago, I began challenging myself with Spotify puzzles: at that time I was dealing with an easy problem; now, the difficulty has increased. The round two consists in the typical “Selection problem“: given an array of values, find the max (or min) k values.
