How effectively delete a git submodule.
View delete_git_submodule.md

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

O(1) Block Propagation

The problem

Bitcoin miners want their newly-found blocks to propagate across the network as quickly as possible, because every millisecond of delay increases the chances that another block, found at about the same time, wins the "block race."

nweb README for version 23
1) Bug fixed - was duplicating errors in the nweb.log file
- thanks to Kieran Grant for stopping this and pointing out the fix.
2) Added support for favicon.ico - if nothing elase this will stop annoying
errors in the log file. Most browsers on first encountering a webpage
also ask for this file. The name mean favourite icon - Wikipedia has
more on this. It is a tiny Bit Map image (normally called .bmp and
BMP editors can be used to create one - I used Windows Paint)
