Currently whenever there is a test, we need to find or build environment on our own machine or borrow some one else's machine temparorily. I hope we can collect all testing machines in our local team and build a sharable testing environment. Every one can reserve and use the machine, add machine, check machine info to find proper one (hardware and software) for test, share vm images, share other testing related resources, etc.

Predicting the non-functional properties of a Ceph cluster can be quite difficult. There are many inputs in the hardware setup and software configuration that affect the resulting availability, reliability and performance (latency and throughput at nominal levels and during degraded and rebuild times).

dropwatch is a utility which can help you to see if data is been dropped in linux network stack.

Ever left a restaurant wanting to write a review, but thinking it wasn't worth the trouble to tap out all those words on your phone -- you just want to give the place your n stars and provide a few words of praise or condemnation? If only you could press a button to generate a plausible review. If this project happens, you will.

A course on Edx -- "Cloud Computing Infrastructure" -- looks very interesting. I want to spend this hackweek to "systematically" learn more about "cloud computing"

Trimatik MC is an older heating control from Viessmann. It has no supported digital interface for remote access, but I found at least two ways to get access to sensor data like various temperatures and state of relay contacts. One way is to use the so called remote control the other use the clock timer. This project will use the latter way, because the hardware adaption is much easier and and all four timer channels could be controlled as well. Remote access will be done via an ESP32, which emulates the clock timer and gets/pushes data via WIFI.
