Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

To remove a submodule you need to:

Delete the relevant section from the .gitmodules file.
Stage the .gitmodules changes git add .gitmodules
Delete the relevant section from .git/config.
Run git rm --cached path_to_submodule (no trailing slash).
Run rm -rf .git/modules/path_to_submodule (no trailing slash).
Commit git commit -m "Removed submodule "
Delete the now untracked submodule files rm -rf path_to_submodule

Running CMSSW with custom ROOT build

Source what's needed:

ssh lxplus
bash
source /cvmfs/sft-nightlies.cern.ch/lcg/views/dev3/latest/x86_64-centos7-gcc8-opt/setup.sh
source /cvmfs/cms.cern.ch/slc7_amd64_gcc700/external/cmake/3.14.5/etc/profile.d/init.sh

Thank you for the interest in GlobalModulesIndex project at HSF group! As this project is highly technical, it is necessary to have some understanding of ROOT and Clang before starting to write proposal. This document is dedicated to give a surface introduction of C++ modules, and to give a project which you can try out.

Build ROOT with C++ Modules

git clone https://github.com/root-project/root
mkdir root-build
cd root-build
cmake ../root -Druntime_cxxmodules=On -Droot7=Off (-GNinja)
make (or ninja)

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft
