Building Stakeholder Confidence

Building Stakeholder Confidence

Confidence in:

  • Production is always up
  • Features will be built correctly

Exercises to Build Confidence

  • Build team-wide, deep understanding of each feature’s requirements and characteristics before coding starts
  • Expect collaborative, comprehensive grooming of features that include team and stakeholders
  • Ruthless slicing of features to smallest valuable increments
  • Write comprehensive automated unit tests in front-end and back-end layers
  • Shoot for high coverage from automated back-end integration tests
  • Shoot for high feature critical-path coverage from end-to-end UI tests
  • Include automated smoke tests that can be run on production-candidates
  • Ensure all post-commit tasks and hand-offs must be automated in CI/CD
  • Strive for quick, reliable rollback if smoke tests fail

Grub error: symbol “grub_calloc” not found. Entering rescue mode… grub rescue.

Since this morning, when i start my laptop, i only see the text:

Grub error: symbol "grub_calloc" not found.
Entering rescue mode...
grub rescue>

I recently updated the packages on my Ubuntu laptop.
I’m guessing it has something to do with the updates for the vulnerability “boothole” in Grub2.

I found this additional information:
https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/GRUB2SecureBootBypass#Recovery

working on this now….

because my laptop is not by default suited for Ubuntu <= 18.04 (did not test on >= 20.04) (because of a video card driver issue).
i could not use the default boot / install USB approach. (installed Ubuntu originally by use of the CLI).

the solution i used for most physical systems is: Boot-repair and running the “recommended repair”.
