I waited for this since I was a boy, and I am loving every second driving this 1986 Ferrari 328 GTS!

A beautiful custom-made cover for the 1986 Ferrari 328 GTS for when I am not driving.

Are you just as excited as I am about deep learning, sparse matrices and tensors, sparse computations, structured and unstructured sparsity, sparse compilers, NVIDIA, and GPUs? If so, please note that my team at NVIDIA is hiring!

YouTube video by Aart Bik Ferrari 328 GTS Antenna

In the weekend, I feel like a Ferrari mechanic. First, I replaced a leaking washer pump. This weekend, I fixed the non-functional retractable antenna. After disassembling everything, greasing the parts, and putting them back, this is the result!

You should be very proud! Finest automobile ever!

Now I know what puts a smile on my face...

Happy Fourth of July!

Of course, my PhD thesis was already available as PDF.

Compiler Support for Sparse Matrix Computations. PhD Thesis, Leiden University, 1996.

In my time, university documents were only available in printed form. However, I found the LaTex sources of my MSc thesis, and was able to generate a PDF form!

A Prototype Restructuring Compiler, MSc Thesis, no. INF/SCR-92-11, Utrecht University, 1992.

Messier 53 through the Meade LX600

Not the greatest capture, but it is Messier 53 nevertheless. Through the Meade LX600, taken with the ZWO CCD.

House of Staunton Sensory Boards and Zmartfun Chess Clock

I very kindly received an updated Zmartfun/HouseOfStaunton Sensory Board that now also features LEDs. You see a side-by-side comparison in the picture. I can't wait to add support for these LEDs to Chess for Android!

It uses recursive backtracking. The implementation maintains its own stack, because the very small 6510 stack itself would overflow for deeper paths ;-)

Maze solving on the Commodore 64 with 6510 assembly. An elegant computer for a more civilized age :-)

Another demo by Aart: control brightness

Always fun to relive the joys of my youth: programming assembler. Check out my 6502-assembler and KIM-1 tutorial.

Moon through Meade ETX90EC

I missed the lunar eclipse due to clouds, but today conditions are a bit better.

No telescope tonight, just my plain phone to get a better overview of the Orion constellation.

Chess for Android connect to eboard menu

iChessOne connected to Chess for Android

The iChessOne board had a firmware upgrade to support board sounds, now also supported in Chess for Android. Simply enable "clock beep" when connecting to this electronic chessboard, and the board will beep with each move!

An old winter favorite again, the Orion Nebula through the Meade LX600.
