Agile Anti-Pattern: No clue about change.
Pattern Description Your company follows a very rigid long-running stage-gate process, which takes around two years between first ideation and go-live. You have three to four releases per year. You cannot change anything which already passed a gate. Issue, Problem, Risk The 1%-requirements creep rule is ignored, thus after 24 months more then a quarter […]

Agile Anti-Pattern: No vision.
Pattern Description You have lot’s of stories converted from an old fashioned requirements specification. You have enough to do for the next years. Your customer is raising the bar and starts to put pressure on your deliveries. Issue, Problem, Risk A rat race is a rat race is a rat race. Nobody knows why he/she […]

Agile Anti-Pattern: Sub-contractor stick & carrot approach.
Pattern Description Your IT department is doing pretty good in using Agil, but somebody from the C-level forgot to ‚agilize‘ your purchasing department and/or sub-contractor management. Thus the contracts with your vendors did not change since 1980 and may be summarized as: Fixed price contracts, Contractually binding requirements specification, Contractual penalties based on Quality gates […]

Arduino IR sensor to trigger onboard LED
Use this sketch to detect an object very close to the IR sensor. This could be useful for model railroading where a train should be detected to trigger a warning light at a level-crossing. // hardware: Arduino UNO, IR sensor from funduinoshop.de // https://funduino.de/arduino-infrarot-abstandssensor // port connected to analog read of IR sensor module const […]

Does your Google search make a difference on your carbon footprint?
The „problem“… Some people (https://www.welt.de/kmpkt/article196360705/Weltretter-Anleitung-6-Wege-wie-du-in-deinem-Alltag-ganz-leicht-CO2-sparst.html) think that it is best to not use Google, because „they are evil“ or whatnot. And then they come up with the CO2 thing and think that something like https://www.ecosia.org will save their souls. Sounds too good to be true, doesn’t it? Well. It is. To get a deeper insight into this, […]

A reply on Michael Küster’s agile anti-patterns
https://failfastmoveon.blogspot.com/2019/07/how-agilists-betray-very-nature-of.html While I agree upon the „badness“ of Michael’s anti-patterns, I would like to add some remarks on my reasons, why he is right. On Agile projects Anti-Pattern „There’s no such thing as Agile Projects! You must do Product Development!“ – can you even smell how dogmatic and close-minded this is? You’re not inviting a […]

How to control effects via MIDI with a Teensy 3.6/LC
Introduction A friend of mine, a keen professional guitar player, wanted a small box to control settings of a looper (a box with which can be used to store audio fragments, loop and stack these fragments). MVP MIDI out (DIN) at least three (configurable) push buttons which send a MIDI control change message a configurable […]

Arduino state machines with function pointers
Rudysmodelrailway implements a railway crossing with blinking lights by introducing a state rdudiagram, which he then in turn implements by switch statements. Here is my take on the state diagram of a (one way) railway crossing with sensor S1 detecting an incoming train and sensor S2 detecting if the train has passed the crossing: This looks a […]

A reply to Michael Küster’s article on „When will the Agile Project be done?“
https://failfastmoveon.blogspot.com/2019/07/when-will-agile-project-be-done.html Dear Michael, this post should serve as a reply to some of the points you made in the post found above. I’ve got some questions… Q: Is „it“ a project? A: A project is a time-boxed endeavor to deliver a specific ‚product‘ with a limited resources. All these three conditions have to be fulfilled. Thus, if you […]

Weighted Shortest Job First (WSJF) and Climate Change.
Based upon a total distance of 200,000 km, an eGolf driven by electrical energy as of today’s German production situation will produce 142 g/km CO2, a Diesel Golf will product 140 g/km CO2. If an eGolf is „fueled“ by wind energy only, it produces 59 g/km CO2. https://www.welt.de/wirtschaft/article192405223/Klimabilanz-Erst-nach-100-000-Kilometern-ist-der-E-Golf-wirklich-gruen.html This is a complete disaster, because no […]
