Colors have a big impact on how software looks. Personally,
|
||
I think macOS and iOS are beautiful and the colors are very
|
||
well selected. Since I am not a designer, but I want to
|
||
understand <strong>why</strong> these systems always looks
|
||
so good, I started designing this website using the Apple
|
||
colors. The first step I took was creating variables for the
|
||
Apple colors from the

|
||
</p>
|
||
|
||
<p>
|
||
I published them on GitHub as gists so you can use them,
|
||
too. It’s just the raw variables; but I could not find them
|
||
anywhere else in this SCSS form. Gist

Many people have ideas. Ideas are not special. What makes
|

and breaks an idea is its realization and/or implementation.
|

Here are some of <strong>my</strong> product ideas.
|
||
Implement them, if you like them! Then send me an

them to me, please. 😁

I love listening to podcasts while I am out running. The
|
||
latest one I found is
|
||
<a href="https://www.happinesslab.fm/">The Happiness Lab</a>
|
||
from and with Dr. Laurie Santos, a professor teaching at
|
||
Yale. She looks at happiness scientifically and takes an
|
||
active approach:

|
||
>You have it in your own hands to improve your
|
||
happiness</a
|
||
>. The podcast discusses various strategies with various
|
||
scientists and experts from their respective field.
|

</p>
|

This is a collection of these strategies you can employ;

This post is a collection of the cool things. I will

probably update it once in a while. Since I am living in

Libraries are an important part of programming. However,
|
||
there should be a <strong>really</strong> good reason, if
|
||
you decide to use a library. And if you use one, it should
|
||
be a good one. These are some from my collection:

This semester I finished my course about automata and
|
||
languages. I learned a lot and it was really enjoyable. From
|
||
this field, there was
|
||
<a
|
||
href="https://old.reddit.com/r/computerscience/comments/atrs4y/pumping_lemma_in_theory_of_computation/"
|
||
>a question about the Pumping Lemma on the computer
|
||
science subreddit</a
|
||
>. So naturally, if someone ask about a thing I know about,
|
||
I’ll try to explain it as best as I can – repetition is key
|
||
for retaining knowledge!

I did it! I bought an iPad and an Apple Pencil for christmas
|
||
last year. I write a lot for my university classes and I
|
||
didn’t like that I often had to cross out things on paper
|
||
(because I wrote something down wrong) and had to write them
|
||
again. I was not sure, if an iPad is the right device for me
|
||
– but turns out it is. It is awesome. If you make a mistake,
|
||
you erase it and write it again. Wrong sequence of your
|
||
sentences? Just move them around. The notes come out
|
||
awesome.
|
||
</p>
|
||
|
||

|
||
Additionally I learned a few gestures that are really
|
||
useful:

Die Rechnung ist eines der wesentlichsten Dokumente des
|
||
Geschäftsverkehrs. Da sie ein formales Dokument ist, müssen
|
||
einige Regeln eingehalten werden, damit eine Rechnung
|
||
<em>gültig</em> ist und der Kunde bezahlen muss. Der
|
||
Gesetzgeber hat eindeutig festgelegt, welche Angaben
|
||
enthalten sein müssen (<a
