With the scarecity of IPv4 addresses, and IPv6 still not available at large, NAT traversal is becoming a necessity. Especially with the generalisation of Carrier-grade NATs that you can find on mobile connections. Even with IPv6 you may suffer NAT66. Imagine your mobile device that gets only a single Ipv6 address, and you want to share it on your computer.
The solution might be in a decentralized protocol for address attribution such
Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.
Prerequisites (for Homebrew at a minimum, lots of other tools need these too):
xcode-select --install will prompt up a dialog)Install Homebrew:
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
The prep-script.sh will setup the latest Node and install the latest perf version on your Linux box.
When you want to generate the flame graph, run the following (folder locations taken from install script):
sudo sysctl kernel.kptr_restrict=0
# May also have to do the following:
# (additional reading http://unix.stackexchange.com/questions/14227/do-i-need-root-admin-permissions-to-run-userspace-perf-tool-perf-events-ar )
sudo sysctl kernel.perf_event_paranoid=0
When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:
const Article = require('../../../../app/models/article');Those suck for maintenance and they're ugly.
