TECH HOUR: Snowflake’s Cortex Code: The Agentic Reckoning

Cortex Code: The Agentic Reckoning,  Or, How Snowflake Finally Gave Data Engineers a Break from Their Existential Crisis (Now With 300% More Technical Guts) Martyn Rhisiart Jones, Madrid, Thursday 26th March 2026 Yesterday I attended Snowflake's breakfast date in Madrid, and here are some of the great things I learned. So, without more ado... Listen up, you glorious data martyrs, you noble sufferers who’ve spent years knee-deep in the festering swamp of undocumented ETL pipelines, chasing lineage graphs that resemble a deranged spider on acid after a three-day bender, and muttering dark incantations at 3 a.m. because some crusty Python script decided “customer churn” meant “every table that vaguely smells like a customer, plus that one VIEW nobody documented since 2019.” I stand before you today, your erudite, slightly unhinged technical prophet (with a heavy dose of stand-up bile and a side order of schema diagrams), to deliver the good news: Snowflake has unleashed Cortex Code, the AI coding agent that doesn’t just autocomplete your misery,  it inhales it, digests the entire governed data estate, and burps back production-grade, hallucination-free SQL, Python, and dbt YAML while respecting your PII tags and warehouse economics like a paranoid compliance officer on Red Bull. This isn’t your garden-variety Copilot having another existential meltdown over a missing import. This is Code Context incarnate, an agentic beast that has swallowed the Horizon Catalogue whole, metadata, lineage graphs, semantic layers, role-based access controls, Dynamic Table lag policies, and the soul-crushing reality of your credit burn rate.

🤪 Oh joyous day! Yet another "revolutionary" runtime promises to finally #sandbox your Node.js app for dainty little #AI tasks, because that's been the burning issue all along. 🚀 Let's all pretend to be shocked when it turns out to be just another way to run JavaScript—this century's version of reinventing the wheel. 🔄

Edge.js: Running Node apps inside a WebAssembly Sandbox · Blog · Wasmer

Today we are incredibly excited to open source [Edge.js](https://edgejs.org/), a JavaScript runtime specifically designed to safely run Node.js workload...

Looking at https://www.youtube.com/@htme it apparently takes a very small group of people only about 10 years to make it from scratch to quite a surprising amount of todays technology.

I kinda expected them to not even make it half the way in that time. But apparently if you know what you're building it is millennia faster than when you don't...

How To Make Everything

Today, getting what you need is as easy as a trip to the store; from food to clothing, energy, medicine, and so much more. Andy will discover what it takes to make everything from scratch. His mission is to understand complex manufacturing and production processes that are often taken for granted, doing it all himself. Each week he'll travel the world to bypass the modern supply chain in oder to harvest raw materials straight from the source. Along the way, he’s answering the questions you never thought to ask. Andy is learning How To Make Everything! Thank you to our patrons for making this series possible!

Oh boy, someone spent an entire weekend reinventing the wheel 🛞 just to find an "OK" color for an image background! 🎨 Because resizing an image to 1x1 pixel and getting mud was too avant-garde for their taste. But fear not, they heroically named their groundbreaking library "Okmain," because apparently "MediocreMain" was too on the nose. 😂

🚀 Wow, setting up a REST API to relay #XMPP messages via HTTP—because why use a direct, efficient method when you can complicate everything for the sake of "integration"? 🤦‍♂️ Just what the world needed: a #tutorial on how to reinvent the wheel by adding a few extra hoops! 🙄📡

Sending Jabber/XMPP Messages via HTTP

The goal of this tutorial is to set up a simple REST API that allows you to send XMPP messages to an existing XMPP account. This can be easily integrated into monitoring solutions or other scripts that send out status information. While there are command-line tools like go-sendxmpp that send messages by connecting to an XMPP server directly, this guide is specifically about providing an HTTP interface. curl "https://ntfy.stdmsg.tech:5281/msg/[email protected]" \ -u [email protected]:secret \ -H "Content-Type: text/plain" \ -d "Your flat white is done" Hint: If you don’t have an XMPP account to receive these messages, you can create one on a public server from within Conversations (F-Droid, Google Play) or another XMPP client of your choosing.

🚀 Oh, look, another forked attempt at reinventing the wheel! 🛞 'Blacksky' tosses some #optimizations and caching into the mix, but who are we kidding? GitHub's got more bells and whistles than a parade of clowns, and this app is just another one of them. 🎪🙃

Ah, the classic tale of reinventing the wheel 🛞! Behold, the famed network server pattern, dear reader: marvel as it twiddles its thumbs for an event, then dispatches like a waiter at a Michelin-star restaurant 🍽️. Forget progress, let's wrap "epoll" and "kqueue" in redundant libraries and call it #innovation. 🚀

Ah, the cutting-edge #innovation of using #tmux and #Markdown to pretend you're managing 48 coding agents 🤣. Who needs fancy orchestration tools when you can just drown in a sea of bash aliases and window naming conventions? 🥴 Clearly, reinventing the wheel is the new black! 🛞✨

🎉 BREAKING NEWS: Someone reinvented the wheel... again! 🎉 Meet #Chorba, the "novel" #CRC32 implementation that nobody asked for. 🤦‍♂️ Because what the world truly needs is yet another way to hash data. Bonus points for the riveting "Skip to main content" intro. 😂

Chorba: A novel CRC32 implementation

This paper describes a novel method for efficiently calculating CRC checksums without lookup tables or hardware support for polynomial multiplication. Throughput of CRC32 is increased by 100% across different platforms compared with the current state of the art. Performance is on par with or exceeds hardware-accelerated solutions on x86_64 and ARMv8 processors, and these hardware-accelerated solutions see a performance increase of 5-20% depending on message length. The small number of operations required with this approach could simplify hardware CRC32 implementations.
