Summary of things I do frequently or that I learned the hard way

Console tips

  • Search for whole words occurence:
ag "\bWHOLEWORD\b" # or
ag -w WHOLEWORD

Advices

  • Always keep your tests in sync with your source code.
  • At the very least, this means in the same repository. Ideally code and tests are updated together in the same commit.
  • Make your startup / boot / init sequence independent of system configuration. Avoid early optimization.

Reproducible build

libraries / ar

With libraries produced with ar, use option D to produce deterministic build.

ar rcsD mylib.a foo.o bar.o

Alternatively one can run ranlib in deterministic mode:

ranlib -D mylib.a

I also made a custom python script ardee.py (that also works on libraries produce by ARM toolchain armar, which doesn't have the D flag)

ardee.py mylib.a

Calendars

Use ICU libraries that deal with all subtleties!
