KDE Eco Sprint May 2022

A week ago I attended the KDE Eco Sprint in Berlin for some experiments around power consumption measurements and tools for that. It has been the first in-person KDE sprint for me since the start of the pandemic, and even happened to be in exactly the same place as the last pre-pandemic one I have been to. Read more

Portmaster: GlassWire Alternative for Linux to Monitor Network

GlassWire is a popular network monitoring app (with no support for Linux) that helps you track data usage, unusual network activity, malicious access to the network, and more. I wish it supports Linux, but for now, it only works on Windows and Android. For Linux, we do not have a full-fledged GUI-based application that helps us monitor the network in Linux. However, I recently stumbled upon “Portmaster”, an open-source network monitor available for Linux and other platforms. Interestingly, it offers some of the same abilities as seen with Glasswire, with some extras. Note that it is not exactly a replacement for “GlassWire” but a potential alternative in the making.

  • How I automate plant care using Raspberry Pi and open source tools | Opensource.com

    Automation is a hot topic right now. In my day job as an SRE part of my remit is to automate as many repeating tasks as possible. But how many of us do that in our daily, not-work, lives? This year, I am focused on automating away the toil so that we can focus on the things that are important. Home Assistant has so many features and integrations, it can be overwhelming at times. And as I’ve mentioned in previous articles, I use it for many things, including monitoring plants.

  • How to flush the DNS cache on Ubuntu Server | TechRepublic

    Sometimes a network connection doesn’t seem to function how we expect them to. And it doesn’t matter how much you troubleshoot the issue, the problem doesn’t go away. You’ve configured a static IP address, you know that configuration is solid and you can ping your gateway, but something is causing that Linux server from reaching the outside world in the manner you expect. One problem could be the DNS cache. DNS is a crucial aspect of networking for all machines, as it translates names to IP addresses. When something goes wrong with DNS, your machine might have trouble reaching the outside world. I have experienced, on a few occasions, a DNS cache to be the problem. When that happens, what do you do? You flush the DNS cache.

  • How to install Podman on CentOS 9 Stream?

    Podman is a container engine compatible with the OCI Containers specification. Podman is part of Red Hat Linux, but it can also be installed on other distributions. As you can expect, Podman is open source, and we can install it on almost any Linux distribution without too much trouble. We could say that Docker is Podman’s main rival. And it is that Podman pretends, with its philosophy, to be a reliable alternative to Docker which is one of the most important container solutions out there.

GNU Chinese Translators Team - Happy 20th Birthday GNU CTT [Savannah]

20 Year ago, May the 28th, GNU Chinese Translators Team was registered at Savannah. I joined the project from Help GNU. My original intention was to support this project and maybe help myself to understand more of GNU. At that time it was only me who worked actively in translating the GNU web pages into Simplified Chinese. I had even had to approve my own translation which was not the correct approach. I really wanted some other people to join the project like the project creators, and I started to really understand that to be a volunteer in a Free Software project means to be persistent and stubborn. Gradually we had some newcomers joining the project, like hagb, hahawang, psiace, shankangke, shi, wind, etc. I am very excited whenever there is a newcomer because I know I am the person to let them know the project and I am the person to encourage them contributing their time and talent in this project.
