A high-performance, zero-overhead, extensible Python compiler using LLVM.
Codon is a high-performance Python compiler that compiles Python code to native machine code without any runtime overhead. Typical speedups over Python are on the order of 100x or more, on a single thread. Codon supports native multithreading which can lead to speedups many times higher still.
A high-performance, zero-overhead, extensible Python compiler using LLVM.
Codon is a high-performance Python compiler that compiles Python code to native machine code without any runtime overhead. Typical speedups over Python are on the order of 10-100x or more, on a single thread. Codon's performance is typically on par with (and sometimes better than) that of C/C++. Unlike Python, Codon supports native multithreading, which can lead to speedups many times higher still. Codon grew out of the Seq project.

PHPStan rules to measure cognitive complexity of your classes and methods.
Cognitive complexity tells us, how difficult code is to understand by a reader.
What matters is the amount of confusion developers feel when going through the code. Confusion costs time and money. Confusion is caused by high cognitive load. It's not some fancy abstract concept, but rather a fundamental human constraint.
Since we spend far more time reading and understanding code than writing it, we should constantly ask ourselves whether we are embedding excessive cognitive load into our code.
Cognitive load is how much a developer needs to think in order to complete a task.
