My favorite configuration for my day job (big tech company, writing high availability storage firmware): - Ubuntu - Git, mercurial, fd-find, ripgrep, exa. - Vim + spf13 + ctags + cscope as a fallback for text-only sessions. - Eclipse CDT: most of my work is C/C++, huge code bases, kernel and userspace. Nothing beats CDT in terms of navigation (go to definition, call hierarchy, class hierarchy, to name a few). It's a little tricky and involving to get the indexing right, but totally worth it. - Gdb and crash (life savers!). For my side projects (mostly rails), it's pretty much the same as above on a mac and vscode instead of eclipse.
