Update (2019-05-06): The Broadcom wireless card in the MacBook Pro works and can be crammed into the Air.

Update (2015-12-04): This document used to be very lengthy as there were many manual steps required to get OpenBSD and Mac OS X working together through Boot Camp Assistant (BCA), which created a hybrid MBR and enabled a legacy BIOS emulation mode which older versions of Windows (and OpenBSD) required. Newer Macbooks stopped supporting older versions of Windows through BCA and now only support Windows 10 since it uses GPT and UEFI. However, now that newer versions of OpenBSD support GPT and UEFI, Boot Camp Assistant is no longer needed at all to boot OpenBSD.

macOS FileVault encryption and OpenBSD encrypted softraid on a Macbook Air/Pro

OpenBSD works pretty well on at least the Mid-2011 Macbook Air (A1370, SandyBridge) and Mid-2013 Macbook Air (Haswell). The new KMS code in 5.4 brings up the MBA's eDP display in 1366x768 with backlight

Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

Unison for file synchronization
EncFS for folder encryption

Backing up a GPG private key to a QR code

Use at your own risk! As with any backup method, test out your backup by restoring from it before you trust it.

Install qrcode to generate the QR code:
```
 pip install qrcode
```
Export the key, piping the output to qr, and save this to a png file:

FreeNAS

I started using FreeNAS in August 2013. It is fantastic piece of software and I have been really impressed by the upgrades just in the few months I've been using it. It looks like they recently went to a plugin system as of version 9 to make installing software easier for end users. I've ran into several issues related to plugins and user + group permissions so I decided to just use the available FreeBSD port system. After fiddling for a few days (now turned into months) I believe I have created something helpful for the community and anyone interested in picking up the port system. The sandbox nature of FreeNAS's jail system is especially helpful for playing around without having any consequence on your core system.

Here are straight-forward instructions to setting up a bunch of different software on FreeNAS. If you make a terrible error, just throw up another plugin sandbox and repeat.

Ikiwiki Tasklist

I love org-mode, don't get me wrong, but as I do more work inside of [ikiwiki], I think I'd like to have an org-agenda like functionality inside of an ikiwiki. I've cobbled together the following script with that goal in mind.

This is probably the best script I've written so far: it has nifty arguments and (some) error checking (see the help text for more), and best of all it works like a dream. The only thing to configure is the

Configuring nginx for SSL SNI vhosts

Gotchas

Note that SHA2 hash algorithm may be not supported on older systems (Windows XP, Windows 2003, among others).
Be aware that mandatory https on SNI vhosts eliminate [Internet Explorer on Windows XP, among others] (http://en.wikipedia.org/wiki/Server_Name_Indication#Web_browsers.5B6.5D).

Remarks

My version of konklones SSL config does not have SPDY support(my nginx+openssl does not support it)
You need a default ssl server (example.org-default.conf).
Some SSL-options have to be unique across your instance, so it's easier to have them in a common file(ssl.conf).
