Race conditions related to insufficient transaction isolation
We have seen phenomenal improvements in the hardware in the last 30 years. Moore observed that the number of transistors in a dense integrated circuit (IC) doubles roughly every two years, the CPU clock rate increased from 740 kHz in 1970 to 4.9 GHz in 2021, and the types of…
Improvements in type annotation, structural pattern matching, better error messages, and performance
Python 3.10 was released on the 4th of October 2021 according to PEP 619. Let’s see what’s in store for us.
Type Annotations
I absolutely love type annotations. Since Python 3.6, they are super useful. If you don’t use them already, I highly recommend you to read my introduction.
Python 3.10 has…
Standards, functions, usage, terminology
PDF is a file format that was created to print in exactly the same way everywhere. It was not intended to be a format for data exchange. Nowadays, it is used in all organizations. …
What it is, aspects to consider, and tools you can use
We all want software to be reliable and use minimum resources. Those are non-functional requirements and they need to be tested. In this article, we focus on web services. This means requirements like minimum energy consumption or mobile network usage are irrelevant.

Switching for a more efficient lightbulb for economic reasons
Electricity is pretty expensive in Germany. We pay around 0.30 EUR/kWh. A normal two person household uses around 2500 kWh/year which makes 750 EUR per year for electricity. This means it’s worth to think about reducing the cost.

So many things that can go wrong
Bug, Issue, Failure, Error, and Defect are often used synonymous, but there are differences:
- An error is a mistake done by the programming error or the usage error. Not every mistake leads to follow-up issues.
- A defect is an error found during the development phase whereas a bug is a…
Boost your productivity and make tests easier to reproduce
Testing is a crucial part of software development. It comes in different flavors such as unit testing, stress testing, acceptance testing, smoke testing. “Just giving it a shot” is probably the simplest of them all, but crucial to be convinced that things work as they should.

Testing is a crucial part of software development. It comes in different flavors such as unit testing, stress testing, acceptance testing, smoke testing. “Just giving it a shot” is probably the simplest of them all, but crucial to be convinced that things work as they should.
Software is evolving all the time. Bugs get fixed, the documentation is improved, it is compiled for new operating systems, ported to other devices, new features are added. New developers get trained and old developers leave the team.
People who think software is once written and then finished got it…
Transactions, Blocks, Consensus, Protocols, and Networks
Bitcoin and Ethereum made it to the news in 2021 due to all-time high price records. People know that they somehow are related to “the blockchain”, but very often the knowledge is rather fuzzy. …
