FreeBSD on a MacBook Pro

Since 2008 or 2009 I work on Apple hardware and OS: back then I grew tired of Linux desktop (which is going to be MASSIVE NEXT YEAR, at least since 2001), and switched to something that Just Works. Six years later, it less and less Just Works, started turning into spyware and nagware, and doesn't need much less maintenance than Linux desktop — at least for my work, which is system administration and software development, probably it is better for the mythical End User person. Work needed to get software I need running is not less obscure than work I'd need to do on Linux or othe Unix-like system. I am finding myself turning away from GUI programs that I used to appreciate, and most of the time I use OSX to just run a terminal, Firefox, and Emacs. GUI that used to be nice and unintrusive, got annoying. Either I came full circle in the last 15 years of my computer usage, or the OSX experience degraded in last 5 years. Again, this is from a sysadmin/developer ki

Like many of us, my company's iOS project:

- Has dependencies preventing arm64 support
- Uses Cocoapods
- Relies upon CI
- Would love to be built with the new Xcode (and LLVM) 5.1 hotness

Since Xcode 5.1's standard supported architectures now includes arm64, we needed to remove that architecture in a way that would persist across clean installs of our pods during our Jenkins CI server's workflow. This is my first time working with Cocoapods, so I had to do some digging to tie up the loose ends.

The first step is simple enough:

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
