Quite some time ago, I read a post (in Czech) by Jirka Eischmann writing about how he connected his blog and Mastodon. It sounded really cool and I was thinking how to achieve the same. But the blog was about Wordpress. And I have a static blog . 'Compiled' into html by Hugo and AsciiDoctor and then served as a static website by Nginx. I found some software that could do some parts of it. Let’s…
We manged to get a booth at this years FOSDEM and went there with Turris and Bird . It was a blast, but let’s talk about that some other time. I want to share my thoughts about one really interesting project I re-discovered there. What is it? Yes, as the title suggest, I’m going to write about Mecha Comet . For those who don’t know, let’s introduce the project. It is open source Linux device,…
I got myself a new toy. Yet another Risc V SBC! I already have a VisionFive 2 that is serving as a 'virtualisation platform' (running several containers) and now I wanted to redo my NAS setup and as I have my drives connected via USB, I was looking for a board with at least 4 USB 3.0. I was thinking some cheap ARM board but than I saw that Orange Pi has RV board. It is same SoC as my VisionFive…
As everybody, I have a smart phone. But half of the last year, I was using a 'not so smart' phone on daily basis. And I was surprised, but I kinda liked it. What was my experience? What unique features did it offer? Was there anything that I was missing? And how does it compare to the life with a smart phone. I actually had a smart phone as my main phone for quite some time. My first smart phone…
Lately I blogged about how am I managing my DNS entries via SaltStack . So far it was about being a great time saver , but nothing that you couldn’t do manually with considerably more effort. This time, let’s take a look at something that would be in some setups almost impossible manually - adding TLSA records for your webs. What is TLSA TLSA records specify SSL certificate used by specified…
In my last post , I showed how we can combine SaltStack and Knot to have some basic records filled your zone. As I was introducing the concept, I picked the most obvious and basic entries. But since we have a hammer now, everything starts to look like a nail. And there is much more that can be stored in DNS apart from IP addresses. Let’s take a look at some other examples and how to get them…
Running services online without domain is hard. More services you run, more DNS entries you need to manage. More services you run, more servers you need to manage. And when you manage several servers, it’s time to use some orchestration. But what about all those domains associated with those servers and services? Can’t that be also part of the orchestration? Somehow automated? Of-course it can.…
This post will be about my approach to something that is almost obsolete. It is about orchestration. Back in the old days, people used to have a real computers or virtual machines and used to install and configure software. And also maintain it for years to come. I know that nowadays, you just create a bunch of pods, each one consisting from multiple containers you downloaded from DockerHub and…
Some time ago, I joined the Fediverse. Why and why now? I actually gave it a try few times already I tried it many years ago with Friendica. I actually run it for a while and posted there but I can’t find any traces of it anywhere so it was a really really long time ago (sometime before 2015). It was nice, but social network by myself is kinda boring so it eventually died out.
I’m using Password store for a long time and I love it. It is simple, intuitive and it just works. Recently I started adding some more formulas into my Saltstack and I started searching for a way how to store some password that are going to be set via Salt. It stand to reason to check whether I can use Password Store with Salt somehow. I found that there is pass renderer already part of Salt…
Recently I decided that my family needs walkie-talkies. My daughter started riding a bike and I needed to stay in contact with her when she ventures too far. Ideally without shouting my lungs out. For my use case I don’t need really big range, I need something cheap that works and supports some kind of filtering so we wouldn’t be disturbed by people using the same frequency. For the…
This is mostly a note to myself. Once in a long while I need to add a new computer as Salt minion. And I always forget how to verify the fingerprints of the key. I know the probability of somebody intercepting the handshake is low, but it is possible nevertheless.
Long time ago, I started writing a blog. Nowadays it is kinda old fashion. People just watch TicTok at best. Nobody reads anymore. I also write less and less. Kinda because it is hard to find the time and hard to finish. I have few articles that I haven’t finished in my old Wordpress instance just lying around. I just can’t get around to finish them. Part of the problem is that I don’t have a time…
My name is Michal Hrušecký, I was born in 1984 in Prague, Czech republic and I’m still living in the same city. I used to work in SuSE Linux s. r. o. as openSUSE Booster. My job was maintaining several packages (for example MySQL related ones), working on Boosters projects, giving talks and presentations and helping community. Then I moved to working in open source team in company called Eaton as…
Smart watches are obviously the cool thing right now. I took a look at few of them and I like some of the features, but so far I haven’t found the one that would be a perfect fit for me. What do I miss? I’ll write about that bellow with few examples of the watches that I kinda like for one reason or other. And if I missed the ultimate one, please let me know!
Let’s start this with a little background. I work at CZ.NIC on Turris project. So I’m definitely biased. But this post is my own, written in my free time and express just my own opinions and it explicitly doesn’t represent opinions of the company I work for unless by chance. So now you know the background, so let’s take a look at what Turris MOX actually is. It is marketed as modular open source…
I’m currently working at CZ.NIC , Czech domain registry on project Turris which are awesome open source WiFI (or WiFi free) routers. For those we developed quite some interesting features. One of them is honeypot that you don’t run on your own hardware (what if somebody managed to escape) but you basically do man in the middle on the attacker and forward him to the honeypot we are running behind…
As you might have noticed , I’m running for re-election. I served my first term as openSUSE Board member, learned a lot and I think I could represent you well for another two years. Although this years elections will be tough as we have in the end quite some strong candidates. So honestly, I have no worries regarding result of the elections as it can’t end badly. Compare it to real world politics…
About two weeks ago I was on the annual openSUSE Board face to face meeting. It was great and you can read reports of what was going on in there on openSUSE project mailing list . In this post I would like to focus on my other agenda I had while coming to Nuremberg. Nuremberg is among other things SUSE HQ and therefore there is a high concentration of skilled engineers and I wanted to take an…
Some people still use paper calendars. Stuff where you have a picture of the month and all days in the month listed. I have some relatives that do use those. On loosely related topic, I like to travel and I like to take some pictures in foreign lands. So combining both is an obvious idea – to create a calendar where pictures of the month are taken by me. I searched for some ready to use solution…
