@ehashman The Technik museum, with punch card looms and embroidery, as well as lots of other technical things.

It's leaf peeping time in Amsterdam!

@jamey The latest BMC version for this mainboard was built April 2019 and is still 2.6.28.9. That's 10 years 1 month after the release. https://lwn.net/Articles/325024/

@nex3 I filed a bug report about the 1201 alarm during descent when the rendezvous radar is enabled. https://github.com/chrislgarry/Apollo-11/issues/23

Jail broke a BMC today and found a truly vintage Linux kernel.

Finally finished "Stranger Things 3" and the part that really required a suspension of disbelief was the full-duplex, zero-latency, noise-free radio connection for the musical duet. It's like the Duffer Brothers have never even called CQ on an DX QSO over an HF band.

No drama llama

Although this is a better future than when I needed a serial console for firmware bringup on a modern laptop. M.2 slot to Mini-PCIe to RS232 UART to DB9 to Null Modem to USB serial adapter.

Biking over Dafne Schippersbrug in Utrecht.

I feel personally attacked by the alt-text in today's xkcd: "Gotta feel kind of bad for nation-state hackers who spend years implanting and cultivating some hardware exploit, only to discover the entire target database is already exposed to anyone with a web browser." https://xkcd.com/2166/

Successfully reconstructed the PNG by hand-generating a correct CRC and fixing the IHDR fields so that the QR code can be displayed (after OCR'ing the fine print on the invitation, figuring out the rotN-cipher and uudecoding the text). Hopefully I'm cool enough to go to their wedding now that I have decoded the invite.

I like my coffee how I like my fundamental nuclear forces.

Utrecht's massive multistory underground bike parking garage has so many ov-fiets.

Low poly is so "In" right now.

Wrap things into curvy circles with

beginShape();
for(let i = 0 ; i < num ; i++) {
let x = R[i] * sin(i * 2 * PI / num);
let y = R[i] * cos(i * 2 * PI / num);
curveVertex(x,y)
}
endShape();

"Wired Love" (1880) and "The Matrix" (1999) share the same duality of hacker lifestyles, separated by more than a century.

Why, yes, I did spend the evening probing the world's fastest parallel hypercube supercomputer (of 1987) to reverse engineer the schematic and backplane pin out.
