My main programming language is Python and I’m a huge fan of static type hinting. As of 2026 there are four type checkers: Dropbox mypy (Python) Microsoft pyright (TypeScript) Facebook pyrefly (rust) Astral ty (rust) I like to integrate them into my GitLab workflow, which includes generatin a Code Quality report. On top of this my pipeline also runs Astral ruff as a linter and code formatter and…
Linters run as part of GitLab Continuous Integration pipelines to guarantee code quality. A Merge Request based workflow will start from a branch main being currently at some commit start. You normally fork a branch develop from that branch base and will create several commits c1, c2, …, cN. When you push that branch and create a Merge Request, a pipeline may start and will run several jobs.

make is used to build projects, e.g. compile source code into binaries. If the project consists of multiple files, explicit dependencies must be specified to run the command in the correct order. In addition to that Makefiles can also be used to track implicit dependencies: If one file is modified, only those commands are re-run which are needed. For large projects that can be a big time-saver if…
Q: How to debug padding and alignment issues of C struct? A: gdb --silent --batch -ex 'ptype /o struct my_t' some.o
The Linux kernel itself and its modules may export symbols, so that other modules can import and use them. As the functions are written in C, it is important that the function signature matches: the number of arguments must match the ordering of the arguments must match the data types must match, which includes the structure and layout of all input and output parameters If any of them changes, the…
Es gab bereits zwei Blog-Eintrag Shell-trivia #1 und Shell-trivia #2 zum Thema set -e. Mein Kollege N. Schier hat mich heute Morgen aber mit einer weiteren Shell-Absurdität überrascht: #!/bin/sh set -e date && false && true date Wie häufig wird date ausgeführt?
