libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse

The Setup

This is a docker-compose file for a simple, secure torrent setup. It includes [rTorrent] (a torrent client), [flood] (a web interface for rTorrent), [OpenVPN] (to tunnel traffic through your ISP) and a simple iptables firewall to allow rTorrent to only access the internet through a VPN.

To run everything, put your open vpn configuration file in ./vpn.ovpn and the other configuration files from this gist in a directory then go to that

# Sign a file with a private key using OpenSSL
# Encode the signature in Base64 format
#
# Usage: sign <file> <private_key>
#
# NOTE: to generate a public/private key use the following commands:
#
# openssl genrsa -aes128 -passout pass:<passphrase> -out private.pem 2048
# openssl rsa -in private.pem -passin pass:<passphrase> -pubout -out public.pem

If you have a certificate that is not
trusted by Android, when you add it, it goes in the personal cert store.
When you add a cert in this personal cert store, the system requires a
higher security level to unlock the device. But if you manage to add your
cert to the system store then you don't have this requirement. Obviously,
root is required to add a certificate to the system store, but it is quiet
easy.
