These instructions are for a Linux system, but if you install Git for Windows ( msysgit.github.com), you will receive a shell and terminal capability. Usual ssh-keygen will write to ~/.ssh/id_rsa (creates 2 files). In Linux, ~ means $HOME, usually something … Continue reading

Debian multiarch: Unexpected complication when building amd64 packages: Can’t install!
This is a multiarch issue I had not considered before. Have you seen it? I never wanted to be a “cross compiler”, I really only want to build amd64. But I have some i386 libraries for a particular program (acroread). … Continue reading

New Linux System Setup: Don’t forget
For all users, put in place some protections and conveniences. In /etc/bash.bashrc or /etc/profile.d/safe.sh, add these alias lines: alias rm=’rm -i’ alias cp=’cp -i’ alias mv=’mv -i’ After that, the removal or destructive file copies will ask the user for … Continue reading
