How to Change Open Files Limit on OS X and macOS

This text is the section about OS X Yosemite (which also works for macOS Sierra) from https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/#mac-os-x

The last time i visited this link it was dead (403), so I cloned it here from the latest snapshot in Archive.org's Wayback Machine https://web.archive.org/web/20170523131633/https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/

Mac OS X

To check the current limits on your Mac OS X system, run:

Golang installation guide

Since Golang version 1.11 this process is finally (almost) as easy as it should (!!). You can see full docs here. For older guides see here.

These are my notes, not a generic solution. They are not meant to work anywhere outside my machines. Update version numbers to whatever are the current ones while you do this.

Installing everything needed the first time

Install asdf and its golang plugin, then install golang

Problem

When starting Emacs.app on Mac, the Emacs doesn't have some environment variable set correctly. Typically it is terrible when you use GPG, pinentry-mac, gpg-agent But also a lot of different variables used to make git works correctly, etc...

Solution

1. Create the file ~/bin/init-app-env.sh:

liweinan

convert -density 100 in.pdf -background white -alpha remove out.png
convert -append `ls -1 *.png | sort -n | tr '\n' ' '` all.png

def to_bits(length, N):
  return [int(i) for i in bin(N)[2:].zfill(length)]

def from_bits(N):
  return int("".join(str(i) for i in N), 2)
