LiMux: Geheimes Rollback, Politik und technische Schwächen

LiMux macht wieder einmal negative Presse – und momentan sieht es so aus, als ob das ehemalige Open-Source-Vorzeigeprojekt der öffentlichen Hand final beerdigt werden würde. So sehr das einerseits stört: An manchen Stellen kann ich das sogar verstehen. Offene, nutzbare Mail- oder Groupware-Clients und Linux sind kein schönes Thema, und selbst nach 20+ Jahren als … Read moreLiMux: Geheimes Rollback, Politik und technische Schwächen

Small-scale microservices in the wild (1): Anachronistic monoliths

Microservices are all over these days. So are frameworks to build different “microservices” from scratch, and so are infrastructure and runtime components to help getting real-life application environments built out of microservices. Using small components to build larger, more complex applications seems so incredibly much the de-facto standard of how to work these days that … Read moreSmall-scale microservices in the wild (1): Anachronistic monoliths

Shipping containers: Lessons learnt from adopting Docker

tl;dr: We started dealing with Docker in Q3/2016 pursuing the goal of adopting it for an existing system infrastructure. By now we do have several production applications deployed and running as Docker containers. It’s a fairly good approach helping you getting standards into your environment and making life a little easier. It has a learning curve though, and a load of advanced features that might get you off track pretty quickly because you’re tempted to deal with them even while you don’t need them (yet). Don’t try to go full-blown container deployment pipeline in one step but rather try to get your environment transformed in small incremental steps. Make sure you feel safe with each increment, gain experience with all things involved in order to avoid losing control of your systems after a big change. Read on for more…

SYN-Flooding für den Geist…

Immer noch und immer wieder habe ich die Hoffnung, daß Technologie Möglichkeiten schafft. Besser Kreativität ausleben können. Viel mehr Tools auf kleinem Raum, die den eigenen Horizont eröffnen und selbst Durchschnittsnutzern Dinge erlauben, die noch vor gar nicht allzu langer Zeit für Profis auf ihren Gebieten schwer bis nicht umsetzbar waren – Kommunikation eingeschlossen, Veröffentlichungen … Read moreSYN-Flooding für den Geist…

XMPP? Nice, but …

I keep on repeatedly promoting and suggesting people to take a closer look at XMPP for their messaging needs instead of falling back to “proprietary” and disputable (yet astoundingly widespread) messengers such as WhatsApp, and repeatedly I fail. And, from some point of view, I have to admit this “failing” doesn’t just happen because of WhatsApps user base being so extremely large. It also happens because, rudely speaking, while providing a load of technical advantages, XMPP is not at all anywhere near WhatsApp, Telegram, Signal or Threema from an end-user point of view. My background here: Professionally, I run an internal XMPP server (on top of openfire) for corporate instant messaging, server alert notifications and group chats for particular purposes. Personally, at some point I tried getting close contacts, family, relatives to use XMPP as a full replacement for any other messenger because I use an XMPP client on the desktop anyway and would like to cut down the amount of tools required for communication…

bookmark-to-mail

Been trying for quite a while to find a reasonable way of managing a “reading list”, with requirements pretty simple: I want to remember a bunch of web resources I stumble across during the day to check them out as soon as I find some time. Tried various approaches, didn’t really enjoy any of them. … Read morebookmark-to-mail

October.

October already, again. Year’s moving on fast. Looking through my history, there are few years that have seen as little activity on this blog as this one. Maybe it’s a a mix of being active in some prominent social networks as well (which ends up being a dump for a load of day-to-day snippets, links random thoughts) all along with lacking really a load of things to write about.

Septembersonne

Der Spätsommer ist heiß in diesem Jahr. Wir haben lang Federball gespielt, bis wir die letzten Bälle ins Dickicht entlang des Platzes geschlagen haben und in der Dämmerung nicht mehr wiederfinden konnten. Nur an den kürzer werdenden Tagen spürt man den frühen Herbst. Die Hinterhöfe sind immer noch voll Musik, die Autos holpern immer noch … Read moreSeptembersonne
