Important @rebeccaplevin.bsky.social article captures so much of what's wrong with how tech is built + deployed into businesses. Top of my list: when you quantify a situation you don't understand, you wind up with data/systems/models that look neat on-screen but are really a mess on the ground.

Even though I've made this joke myself I actually really hate the "all developers have to be engineering managers now with agents" No, they all need to be tech leads, not ems.

🌿 NEW STORY DAY🩸 “Drosera regina” is about a woman whose body behaves like a carnivorous plant, attracting men whether she likes it or not. Read here: www.lightspeedmagazine.com/fiction/dros... Listen here: tinyurl.com/drosera-regina Art by the talented @headfullopuddin.bsky.social
Art by Becca Snow. A woman struggles to keep her head above water as she in ensnared by various objects: a boat, a hammer, a helmet, etc. Sundew stalks surround her head. The men knew before she did. Before this boy, before sophomore year, before even her twelfth birthday, they had jostled her on the sidewalk and hooted from cars, searching for something just past her skin. But now, with her panties stripped off and the boy’s eyes on her, Jackie felt a strange prickling. A warning pacing behind her ribs. A mouth about to drip.

There’s a weird and unexamined tension between the “AI makes it possible for unskilled people to write complex code” and “you need to start learning how to use these tools or you’ll be left behind” lines of rhetoric in a lot of recent AI codegen writing I’m seeing.

"Kings hammer mistrust into swords, demand battle songs, and the world deafens with terror of one's neighbour. I turn to words. Their little lamps will outlive my flicker, that of lords, and of this current fear. [...]" - by Rosie Garland - @rosiegarlandwriter.bsky.social
Bede writes a history of the English people
Rosie Garland

Ask, why I carve feathers to the spike of knives
when men are too busy to read. I should be bricking
windows into arrow-slots; should be bending
yew to longbows. The year roars with blood,
the murder of faith, and enemies close, closer.
Kings hammer mistrust into swords, demand
battle songs, and the world deafens with terror
of one's neighbour. I turn to words.
Their little lamps will outlive my flicker,
that of lords, and of this current fear. I grind
gall, vinegar, hone my quill. Feed the dark age with light.

I started working on this full-sized 3D-printed Stormbreaker replica in late 2019 as a Halloween costume prop. Almost 5 years later, it’s finally finished and mounted on my office wall. 100+ hours of printing, over 4 feet long, weighs several kg. I’m pretty pleased with how it turned out.

The existing integration between Iceberg and Glue is a confusing mess, so it’s heartening to see AWS full-throatedly embrace Iceberg after kicking Lake Formation Managed Tables to the curb earlier in the year. Very interested to see what they’ve done with the Athena and Spark integrations for this.

There’s a lot of excitement about S3 compare-and-swap support lately, particularly as it concerns Iceberg and the ability for “metastore-less” transactions. Personally, what I’d love to see come out of this is metastore-agnostic support for multi-table transactions. I miss those. #dataBS
