A few of the reference slides from the "Atoms of Emergence" 500-level chalk talk I'm doing at re:Invent. Really looking forward to really digging into some of the surprising emergent behaviors in request response systems, metastability, and more!

I'm a shameless Amazon shill, but one of my favorite tricks is to use the "save for later" feature in the shopping cart and then when Prime day hits see what's on sale. That and the 5% extra off with a Prime Credit Card feel like cheat codes.

Are you kidding us @cityofmlt.bsky.social - I can’t even open this safety alert to see what it is. At least update the bitly link to something that isn’t behind a twitter login. Please consider the signal to noise ratio on these carefully too.

I got up this morning before 5 to take some photos of Dublin's dawn, but I didn't expect to see a red fox on Sandymount Strand. Super chill little guy.

I took this photo yesterday and it made me wonder ... why does Seattle's monorail ride on the left?

We traced the Potomac with some high bank turns, and got a great view coming in to DCA.

Here's my t-shirt from the NET201 session at AWS re:Invent for no particular reason.
