The Adventures of Dash Daring in Code & Music & Business
When You are working with different operating systems you encounter different line endings. Editing a file on a Linux system and opening it on a windows machine can give a weird result.
Here is a short overview which system uses which command characters:
| OS | Command character |
|---|---|
| Windows | CR + LF |
| Linux | LF |
| Mac OS <= 9 | CR |
| Mac OS X | LF |
If You already read Python pip and virtualenv you are familiar with the way python handles requirements. but lo and behoild there is a new kid in town or actually two new kids on the block: Pipfile and Pipenv – both with with a capital “P”.
If you are tired of creating and maintaining your virtual envrionments, requirements.txt and requirements_to_freeze.txts: Enter Pipenv! Continue reading “Python Pipfile and pipenv”
The dark ages are the years between stopping playing with LEGO as a child and starting again to play again as an adult. In my case more than 20 years.
When my older daughter turned 4, we decided to give her her first LEGO as a birthday present and we ended up spending our afternoons on weekends building and playing with her LEGO. When my 37th birthday arrived I was so hooked again that I decided to buy my first set in over 20 years. That is what You call an AFOL – an Adult Fan Of LEGO.
LEGO Creator Expert
for this exact species LEGO has a number of sets ibn their portfolio called Creator Expert with lots of pieces and sophisticated building techniques.
Have a lock at it yourselves:

My Collection
sorting
https://rebrickable.com/ let’s you manage your Lego collection either via set lists or part lists
https://rebrickable.com is also a page where AFOL can share their MOCs. A big advantage: when you share your MOC you have to provide build instructions
Not to confuse with MILF, a MILS or Modular Integrated Landscaping System is a concept to build bigger Lego landscapes via assembling smaller modules.
To work with OpenCV from python, you need to install it first:
pip install opencv-python
After we import cv2 we can directly work with images like so:
import cv2
img = cv2.imread("doc_brown.png")
A cool new feature made its way into Python 3.7: Data classes.
Since Python 3.6 there is neat way to put variables into string, called f-strings:
name = "joern"
age = "37"
print(f"My name is {name} and I'm {age}")
After trying a couple of times to get into a Management 3.0 training I finally had the chance to participate in a two day course in Nuremberg. Continue reading “Management 3.0 Workshop”
Let me bring some clarity into this topic!
With numpy you can easily create test data with random_integers and randint.
numpy.random.randint(low, high=None, size=None, dtype='l') numpy.random.random_integers(low, high=None, size=None)
random_integers includes the high boundary while randint does not. Continue reading “numpy random choice”
In the realms of Data Science you’ll encounter sooner or the later the terms “Precision” and “Recall”. But what do they mean?
Living together with little kids You very often run into classification issues:
My daughter really likes dogs, so seeing a dog is something positive. When she sees a normal dog e.g. a Labrador and proclaims: “Look, there is a dog!”
That’s a True Positive (TP) Continue reading “Classification: Precision and Recall”
