"Scar Tissues Make Relationships Wear Out"

04/26/2103. From a lecture by Professor John Ousterhout at Stanford, class CS142.

This is my most touchy-feely thought for the weekend. Here’s the basic idea: It’s really hard to build relationships that last for a long time. If you haven’t discovered this, you will discover this sooner or later. And it's hard both for personal relationships and for business relationships. And to me, it's pretty amazing that two people can stay married for 25 years without killing each other.

[Laughter]

> But honestly, most professional relationships don't last anywhere near that long. The best bands always seem to break up after 2 or 3 years. And business partnerships fall apart, and there's all these problems in these relationships that just don't last. So, why is that? Well, in my view, it’s relationships don't fail because there some single catastrophic event to destroy them, although often there is a single catastrophic event around the the end of the relation

OpenShift Origin in AWS

This describes deploying and running OpenShift Origin in Amazon Web Services.

This is based upon the code and installer on 2014-02-26 so YMMV.

We will be using a VPC for deployment in us-east-1 and Route53 for DNS. I will leave the VPC setup as an exercise for the reader.

Prerequisites

• AWS Account
• VPC

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

A box-and-whisker plot with axes. Based on Mike Bostock's implementation. Instead of using individual svg elements as in Mike's implementation, here all boxplots are rendered with in one root element. This makes it easy to add axes.

Further differences between the two implementations are:

• visibility of boxplot labels can be switched with the labels variable
• CSV files are supported in which each column is an independent variable and each row contains measurements for all variables (see data.csv)
• transitions are not used here but can be easily added again
