How to compile Mesos on your new Raspberry Pi 2 (which is amazing with 4 cores and 6x performance). Follows on from experiments in compiling for OS X

sudo apt-get install maven libsasl2-dev libapr1-dev libsvn-dev libcurl4-openssl-dev python-dev python-boto

export JAVA_HOME="/usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt"
export PATH=$JAVA_HOME/bin:$PATH

#Container Resource Allocation Options in docker-run

now see: https://docs.docker.com/engine/reference/run/#runtime-constraints-on-resources

You have various options for controlling resources (cpu, memory, disk) in docker. These are principally via the docker-run command options.

##Dynamic CPU Allocation -c, --cpu-shares=0
CPU shares (relative weight, specify some numeric value which is used to allocate relative cpu share)

This script enables you stop and start Symantec Endpoint Protection on OS X

Installation

sudo curl https://gist.githubusercontent.com/steve-jansen/61a189b6ab961a517f68/raw/sep -o /usr/local/bin/sep
sudo chmod 755 /usr/local/bin/sep
sudo chown root:staff /usr/local/bin/sep

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

Expand virtual hard drive

VBoxManage modifyhd OSX\ Dev.vdi --resize 40960

Resize GPT

Solves "MediaKit reports partition (map) too small" error from Disk Utility

Mount virtual image via nbd sudo qemu-nbd -c /dev/nbd0 OSX\ Dev.vdi
Use sudo gdisk /dev/ndb0 to destroy and recreate a partition table.

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real
