(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

AutoHotkey script to map Caps Lock to Escape when it's pressed on its own and Ctrl when used in combination with another key, à la Steve Losh. Adapted from one that does something similar with the Ctrl Key on the Vim Tips Wiki (http://vim.wikia.com/wiki/Map_caps_lock_to_escape_in_Windows?oldid=32281). (Plus contribs from @randy909 & @mmikeww.)
g_LastCtrlKeyDownTime := 0
g_AbortSendEsc := false
g_ControlRepeatDetected := false
*CapsLock::
if (g_ControlRepeatDetected)
{
return
}

This script analyzes the dependencies between top level types in a .NET Assembly. It is then used to compare the dependency relationships in some F# projects with those in some C# projects.

This JSON.Net converter handles F# discriminated unions with more "idiomatic" JSON than what is generated by the current version of JSON .NET. Option types and single case DUs are transparently handled, and tuple-style properties are used rather than array notation.

Elm 0.15.1 vs 0.16 on Chrome

Result of running these benchmarks on Chrome 45.0.2454.101

These numbers seem to be pretty consistent on Blink-based browsers (Chrome and Opera) but are more like 20% to 50% improvements on FireFox, Safari, and IE. I am not sure how to explain that, so take these numbers more as an indicator of “Elm is generating faster code across the board” as opposed to “Elm is 10x faster!”
