@elastic.co 's Agent Builder is basically a Build-A-Bear store for creating custom #a2a agents and #MCP server tools and I love it! I have 100k of manufacturing logs and it chomped through them like it was nothing. I love this evolution of LLM-focused data retrieval! ela.st/agent-builde...

In "Memory Serves" S02E08 of Star Trek: Discovery they've ran an analysis of a space probe from 500 years in the future. A crew member states that the probe used multiple SQL injections. My sweet space siblings in Christ, why on God's green Galaxy are we still using SQL in the year of our Q 2758?!

Lotta cis white men in their feelings right now across America. So many pearls clutched to hairy chests.

Daughters is done. Daughters is over. But sometimes you crave the darkness and the sexy chaos. You want to grind your tooth against the floor until it hits the root. But Daughters is gone. May I recommend Chalk? Belfast always coming out with those sick bands. chalkbelfast.bandcamp.com/track/afraid

Afraid, by Chalk

At the MS Build conference they announced new Azure data centers that are epically huge and complex and amazing. They also boasted 100% renewable energy consumption and using eco-friendly building materials such as laminated timber product and bio-sourced micro-algal sandstone in the concrete...

Either Forest Whitaker has masterfully overacted Saw Gerrera or they're prepping for an amazing series on him. He's always stealing scenes! #spaceghostdog

Hey everyone, check out our Daily Elastic Byte series covering Open Telemetry with Elastic! Super excited to be on camera again sneaking in the dad jokes and getting people informed and empowered with tech!

Got to pair program with @jessicagarson.bsky.social yesterday and a bit today on an @opentelemetry.io and Elastic project that we both wanted to explore. Just to state the obvious: even established developers can still benefit from using their words and sharing their brain power to get stuff done!

Since I have the privilege and access, I might set up an Observability program with my house. I'll be the trace and the spans can be my daily comings and goings. Just requires a LOT of IoT devices and a little bit of code everywhere. This could be fun or creepy.

Has anyone installed a smart monitor onto their power panel? I'd love to track that data and play with it. Figure out hidden cost/energy-sappers and make better informed decisions.

My feefees hurt bad when I went another 13k into debt after installing a heat pump into my house buuuuuuuut the fact that my house is comfortable (to me) and I can claim a 2000 credit on my tax return is kinda cool, right? #taxisntreal

So some of us got a bit of a shock when we opened our Spotify Wrapped this year. No, Taylor was NOT my #4. You can craft a custom "Wrapped" with Elastic packed with your ACTUAL top songs, artists, and trends from 2024! Check out this guide to get started: www.elastic.co/search-labs/...

Having to admit to a non-US coworker that I took a day off for grief, recovery, and action from the Inauguration is a trip. This time around, I will not be aghast, but be combative. I will not wait out the four years. I will make it a hell for them.

Shout-out to @kitsaptransit.bsky.social having foot ferries from Southworth to Seattle. As someone who's taken the ferry as a teen and into my 40s, I still love every ride.

So you'd sign up for Communism if it meant healthcare, rent, and groceries were affordable.

I'm headed to see #deathfromabove1979 play their entire album 'You're a Woman, I'm a Machine.' Supremely stoked. It's the album's 20 year anniversary. Also I made the adult decision to take the day after off and get a hotel above the venue. Geriatrically Grateful.

Last night I was bored out of my skull (I'm recovering from a nasty cold) and I wanted to get out of the house so at 9pm I drove to Safeway and gathered the ingredients to make a McDonald's clone of a McSausage Biscuit breakfast sandwich. It was delicious. No Ragrets.
