### Pipenv Easter Egg

I’ve found this little easter egg hidden in pipenv: if not environments.PIPENV_HIDE_EMOJIS: now = time.localtime() # Halloween easter-egg. if ((now.tm_mon == 10) and (now.tm_mday == 30)) or ( (now.tm_mon == 10) and (now.tm_mday == 31) ): INSTALL_LABEL = “🎃 ” # Christmas easter-egg. elif ((now.tm_mon == 12) and (now.tm_mday == 24)) or ( (now.tm_mon ==…

### 2021 – Advent of code – Day 3

Part 1 You need to use the binary numbers in the diagnostic report to generate two new binary numbers (called the gamma rate and the epsilon rate). The power consumption can then be found by multiplying the gamma rate by the epsilon rate. Each bit in the gamma rate can be determined by finding the…

### 2021 – Advent of code – Day 2

Part 1 Today the puzzle got a bit trickier than Day 1. The submarine seems to already have a planned course (your puzzle input). You should probably figure out where it’s going. For example: forward 5 down 5 forward 8 up 3 down 8 forward 2 Your horizontal position and depth both start at 0.…

Da sich aber alles hier auf die spezielle…

### 10 tips for creating co-ownership in a code base

When you learn a new language or a framework you almost always certainly start fresh with a new clean project aka green field project. In the industry you rarely get the chance to do so. You will have to start with code which has already been there for a specific time. These projects are called…

### What is the Karman line?

tl;dr; The Karman line defines the edge of space. It is set to 100km above the Earth’s mean sea level and separates aeronautics from astronautics. So to be an astronaut you have to travel higher than 100km from Earth’s surface. Why is that? To fly with a conventional airplane you need the air to generate…

### What is LEO?

LEO stands for Low Earth Orbit. It ranges from 200km to 2000 km. The ISS orbits the earth between 370km and 460 km. Due to atmospheric drag the orbit decreases over time The Hubble Telescope orbits a bit higher at 545km to 549km Other orbits Overview Satellite Orbit ISS 400km Hubble 545km Starlink 550km Iridium…
