The Demise of KaiOS - Alcatel 3088X

Image
I was really excited, when Firefox OS became commercially available as KaiOS for "smart" feature phones. Unfortunately the high hopes I had put into this platform have been utterly shattered. I was recently looking for a button phone that had only three requirements : very good battery run time, at least several days or a week of standby without charging easy backup or even synchronization of the contacts VoLTE support to benefit from LTE coverage  In Theory... On paper, KaiOS phones look like the perfect match for those requirements. PhoneCopy for KaiOS is a cloud synchronization service that comes with an app for KaiOS (and many other platforms) to synchronize contacts and other phone content to the cloud (and back). With batteries of 1500 mAh and more , KaiOS phones have the potential to deliver outstanding battery performance. The Alcatel 3088X , for example, boasts "up to 300h standby and more than 7h talk time" with a 1530 mAh battery: Battery specification

The GitOps Journey

Image
I talked about this at the GitOpsCon EU 2021: The GitOps Journey Video The GitOps Journey Slides GitOps is most definitely one of the hype words of 2021. No self-respecting tool fails to market itself as a "GitOps tool, even if is only remotely related to the GitOps principles defined by the CNCF GitOps Working Group . But where does GitOps fit into an IT strategy? In my opinion GitOps should be the centerpiece of every modern IT strategy! The GitOps journey takes the hype surrounding GitOps to build a solid, automation-focused, long-term sustainable IT strategy. A strategy that uses standard "GitOps" tools together with our own developments to navigate the deep waters between DevOps chaos and widening the Dev-Ops gap towards true hands-off operations where the Dev or Ops question is mostly irrelevant as we all use the same common automation and tooling.  GitOps is the natural evolution for DevOps practices . Challenges of e

10€ remote doorbell

Our door bell is not very loud and we don't hear it in the kitchen when the internal doors are closed. We already missed people calling at our apartment door because of this. To solve this problem I found a 10€ remote bell that sits in the kitchen and rings whenever somebody rings our door bell. Initially I wanted a fancy WIFI based solution based on an ESP32 that would call me via SIP... But in the end this simple solution is "good enough" and has the benefit of zero maintenance. My solution is based on a kinetic wireless doorbell  (batterielose Funktürklingel) that has two components: A ringer that sits in a power socket and a transmitter without batteries. The "without batteries" part is really important as it allows a direct connection and integration of the transceiver into the door phone. As it happens, what I needed was available for 10€ at a local supermarket, but you can easily find this type of doorbell in online stores as well. The ringer contains a l

How did GitOps get started? An interview with Alexis Richardson

Image
As part of the research for my upcoming GitOps article in the iX magazine , we -  Johannes Schnatterer and I  - had the opportunity to interview Alexis Richardson , founder & CEO of WeaveWorks , about how he invented GitOps - both the concept and the term. The interview covers Alexis' views on GitOps, Kubernetes and gives an interesting insight into his company and their take on Open Source.
