When you use ssh with X forwarding, you might have noticed that you cannot execute programs that require 3D acceleration. That's where VirtualGL comes into play.

"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

	Summary of what events this fires:

	dragover (repeat until it moves)

	1) On Raspberry pi , run the camera and stream using gstreamer as below:
	raspivid -t 0 -w 800 -h 600 -fps 25 -g 5 -b 4000000 -vf -n -o - \| gst-launch -v fdsrc ! h264parse ! gdppay ! tcpserversink host=192.168.0.106 port=5000


	2) On Ubuntu desktop, run the local rtsp server as below:

	import numpy as np

	def rmsle(h, y):
	"""
	Compute the Root Mean Squared Log Error for hypthesis h and targets y

	Args:
	h - numpy array containing predictions with shape (n_samples, n_targets)
	y - numpy array containing targets with shape (n_samples, n_targets)
