I wonder how sweetie đťś‹ will react to this news.

This is true, but there are a couple of easy workarounds for it: Cython and scipy.weave

That was #&<%ing awesome!
Another even better guess is that the udacity self driving car course [1] will see a huge upswing in enrollment.

If you want an open sourced car racing game server, you can always use TORCS [1] and SCR [2].

Its a good guess that the simulator or game engine behind this competetion is TORCS (The Open Racing Car Simulator) [1].

Simulated Car Racing (SCR) [2], is an existing annual AI car racing competition based on TORCS, though without the attractive prizes. It also has a client-server architecture with controls and sensor information sent over UDP using what seem like lisp sexps.

Please add `man -k' to the list of unix commands worth memorizing

For some reason ubuntu's network manager crashed and I was in a spot as I couldn't access google to figure out how to fix it.Playing around with `man -h', I discovered `man -k', which lets you search the linux command documentation. `man -k network' brought up nm-applet, the command that restarts the ubuntu network manager. I just wish I had known about `man -k' earlier.

My first impression is that nd-array/matrix manipulation sucks big time in golang, compared to matlab or python/numpy. I'll go further and say it sucks even compared to C++ and vanilla C.

What raised the English-speaking peoples to greatness was not a magical property in their DNA, nor a special richness in their soil, nor yet an advantage in military technology, but their political and legal institutions.

This is no doubt aimed at Jared Diamond's "Guns, Germs, (Geography) & Steel"

If Dean has a superhuman power, then, it’s not the ability to do things perfectly in an instant. It’s the power to prioritize and optimize and deal in orders of magnitude. Put another way, it’s the power to recognize an opportunity to do something pretty well in far less time than it would take to do it perfectly.

The take away message is that Worse is Better!

Thanks for posting.

Now I get why Kepler was hell bent on trying to fit the orbits of the 5 known planets (at his time) with the 5 platonic solids [1]. This part of Kepler's life is very nicely depicted in Carl Sagan's Cosmos [2]. It seemed interesting when I watched it, but I didn't give it much thought back then.
