brew is a bad neighbor

This isn't a guide about locking down homebrew so that it can't touch the rest of your system security-wise.

This guide doesn't fix the inherent security issues of a package management system that will literally yell at you if you try to do something about "huh, maybe it's not great my executables are writeable by my account without requiring authorization first".

But it absolutely is a guide about shoving it into its own little corner so that you can take it or leave it as you see fit, instead of just letting the project do what it likes like completely taking over permissions and ownership of a directory that might be in use by other software on your Mac and stomping all over their contents.

By following this guide you will:

• Never have to run sudo to forcefully change permissions of some directory to be owned by your account

# Put this function to your .bashrc file.
# Usage: mv oldfilename
# If you call mv without the second parameter it will prompt you to edit the filename on command line.
# Original mv is called when it's called with more than one argument.
# It's useful when you want to change just a few letters in a long name.

The “Positive SSL” certificate I bought along with my domain is invalid with any of my subdomains and cannot be used with wildcards. One annoying thing is that namecheap doesn’t offer auto installation of free let’s encrypt certificates, even though, they are saying “Namecheap is dedicated to data security and privacy for all internet users. We believe the movement to encrypt nearly all web traffic is a positive direction. As more sites embrace HTTPS and use of security products, providers of free SSL are beginning to come online.”

Let me show you what it needs to be done in order to “encrypt nearly all web traffic”.

First, not required but it’s helpful to enable ssh access, it is not enabled by default on the base hosting plans, just go an start a live chat and request ssh access.

That's it - I've finally lost it with Linksys and both my WRT 1900ACs that are only a year old are getting chucked. Don't get me started on all the reasons why, but it's primarily down to continued degradation of wifi signal and the constant need for reboots. Going by the responses to this tweet, that's just what they do: https://twitter.com/troyhunt/status/778867707655487488

I’m going all out with Ubiquiti instead. No, I'm not interested in [insert the other thing you think rocks here], there's a really vocal majority in favour of Ubiquiti so that's that. Now I need help speccing out what I need for my house as it’s not quite as straight forward as just chucking in a couple of (dodgy) routers.

Here’s what I’m working with:
- Large multi-level house about 500m2 (needs at least 2 APs, probably more)
- Wired ethernet to every room (I believe Cat 5e, was here when I got here)
- Patch board in the garage and a 100Mbps hub (running patch cables out to a Linksys 8 port gigabit switch instead)
- 4 wired connection
