@brunoph Thank you for Mastodon.app. I hope for more features 😄

In meinen Vorträgen hab ich diese Probleme bisher immer theoretisch beschrieben. Der Lidl-Thermomixer bestätigt eindrucksvoll, dass wir zuwenig Verbraucherrechte im Smart Home verankert haben.
Es darf nicht sein, dass solche Massenprodukte so unsicher verkauft werden.
"Wir wollen keine Hintertüren für verschlüsselte Daten."
"Wir wollen einen staatlichen Zugriff auf verschlüsselte Daten."
"Big-Tech"-Konzerne wie Google und Facebook sind das Ergebnis von hunderten Unternehmensfusionen. Von den meisten Unternehmenskäufen bekommt die Öffentlichkeit gar nichts mit. Aber das ändert sich gerade. Die New York Times haben einmal visuell aufbereitet, wie #Google und #Facebook so fett geworden sind.
19.2. Gherkin is your friend to understand expectations
Gherkin is a test description format which points "Given that <a system is in a certain state>, When <something happens>, then <this is expected>". Even if you don't use any testing tool that reads Gherkin, it will give you a good understanding of what it is expected from the app.
19.1. Write steps as comments
If you have no idea how to start, describe the flow of the application in high level, pure English/your language first. Then fill the spaces between comments with the code.
Better yet: think of every comment as a function, then write the function that does exactly that.
18. Shortcuts are nice, but only in the short run
A lot of languages/libraries/frameworks add a way to make things shorter, reducing the number of things you need to type.
But, later, that will bite you and you'll have to remove the shortcut and do the long things.
So learn what the shortcut does before using it.
17 1/2. The Magical Number Seven, Plus or Minus Two
"The magical number" is a psychology article about the number of things one can keep in their mind at the same time.
If you have a function, that calls a function, that calls a function, that calls a function, that calls a function, that calls function, you may be sure it will be a hell to read later.
Think more about: I'll get the result of this function, then pass it to the second function, get its result, pass to the third an so on.
17. Cognitive Dissonance is the readability killer
"Cognitive dissonance" is a fancy way of saying "I need to remember two (or more) different things at the same time to understand this."
For example, adding booleans to count the number of True values is a mild cognitive dissonance 'cause one can think "What do you mean True plus True equals 2?"
14 1/2. Design patterns are used to describe solutions, not to find them
(Again, personal opinion) Most of the time I saw design patterns being applied, they were applied as a way to find a solution, so you end up twisting a solution -- and, sometimes, the problem it self -- to fit the pattern.
First, solve your problem; find a good solution; then you can check the patterns to know how you name that solution.
13. Companies look for specialists but keep generalists longer
If you know a lot about one single language, it may make it easier to get a job, but in the long run, language usage dies and you'll need to find something else. Knowing a bit about a lot of other languages helps in the long run, not to mention that may help you think of better solutions.
