A Practitioner's Guide to Wide Events | Jeremy Morrell
The existing articles on Wide Events define the concept well but leave the implementation details to the reader.

There have been some good posts on what "wide events" instrumentation is but not as many on how to go about it, what attributes you should add, or how to work with OpenTelemetry
I put everything I've learned in the last few years into one guide jeremymorrell.dev/blog/a-pract...

Kyle Kingsbury is not a journalist. He is not an op-ed writer.
He is a computer safety researcher.
And he has written one of the most compelling, comprehensive accounts of the ongoing hell in Chicago that you could possibly imagine.

it’s very clear more democrats agreed with this deal but strategically had those who aren’t up for election soon do the dirty work. it doesn’t mean we can’t make their lives a living hell until & through then, and it doesn’t mean we should take the dems that performed “no” on here as being truthful

ICYMI, servers got good, which means that if your data is smaller than ~8TB (yes, TB), it's not "big data", it's "thing you can grep in memory in near real time."

You can't compare the stock of *value* like corporate valuation to economic *output* like GDP. It's like saying your car makes up "30% of your annual income" because it's worth $30k and you make $100k.
A $5T valuation is big but total US household net worth is like $167T

There’s something magical about physics-based animation. When we use springs instead of Bézier curves, we tend to get way smoother motion.
Up until recently, we’ve needed to use JS libraries for this, but a modern feature lets us emulate springs in native CSS. ✨
