The slowness of my zsh prompt when in a git-svn managed directory was killing me. I improved it by removing the git status stuff that slows it down...

ref=$(git symbolic-ref HEAD 2> /dev/null) || return
echo "$ZSH_THEME_GIT_PROMPT_PREFIX${ref#refs/heads/}$ZSH_THEME_GIT_PROMPT_SUFFIX"

A single function that uses a bunch of C++11/14 features and for "old-school" C++ developers will not even read like C++ anymore.Specifically, it uses:- lambda functions (C++11) with generalized capture semantics (C++14)- rvalue references (C++11)- auto variables (C++11)- decltype and trailing function return type syntax (C++11)- std::move and s…

Convert a disk from MBR to GPT+UEFI, in Linux.

Before starting, make sure you have a backup, and make sure to have a linux live boot ready to rescue your system. It's easy to mess this up!

  1. Use gdisk to convert the partition table to GPT.

    gdisk /dev/sda

  2. Create the "BIOS boot" partition that GRUB needs.

    n to create a new partition. Needs to be about 1MB. You can probably squeeze this in from sectors 34-2047. Use L or l to look up the code for "BIOS boot" (ef02).

  3. Write the new partition table.

    w

  4. Reload the partition table. > partprobe /dev/sda
