After announcing the @elastic.co Agent Builder on our YouTube and dev (@elastic-dev.bsky.social) channels, I played around with it some more to build a #SpotifyWrapped generator based on a previous blog I wrote! I build my own ES|QL tool and musical agent 🎵

Just when I finally used up months worth of #audible credits to get all the #HarryPotterAudiobooks, they announce the new full-cast ones are coming out soon 😭

Gone from filming in every random corner of my student apartments to finally having a fixed "studio" for my videos. Only took 6 years since the first #youtube video 😅

Is generating fake videos the best AI has to offer? Are we using too much inference power with little to show for it? Is the slop making too much noise to appreciate real AI value anymore? Some thoughts:

A 300h Civ Six girly just bought Europa Universalis, Anno 1800 and Old World in the 90% off autumn steam sale. Wish me luck, won’t resurface for a few days.

If you're in Amsterdam next week - we're hosting another meetup at our @elastic.co office!
I'll be giving a talk on "Embeddings - LLMs - vector / semantic search - GenAI - RAG - agents - MCP" (aka acronym and buzzword bingo).
See you there!

We’re at @pydata.bsky.social #Amsterdam today with @elastic.co. Come by our booth if you wanna chat about AI in search or observability and otel 😉. Or just for some cool stickers and socks 🧦

I've been releasing loads of new content on our @elastic.co YouTube community channel.
Covered #LLMs, #RAG, #agents, #MCP, and the latest on #contextengineering.
Yes, I'm basically playing buzzwords bingo / catch 'em all.
And yes, I've also mastered "YouTube thumbnail posing". #hatethegame

I am sooooo beyond excited to keynote #PyCon Sweden this year!! This is a truly special event with a lovely community in a wonderful city. I am so proud to come back in this role and I hope the talk will be useful or at least interesting to the pythonistas joining ;)
See you on halloween!! pycon.se

#CDN Romania thank you for an amazing conference experience!
Great crowd and discussions, amazing speakers, lovely organisers, good location and food <3
I was so happy my talk about building @elastic.co analytics dashboards from your data (like an accurate DYI Spotify Wrapped!) was well received!

The only way we can get great results out of LLMs is if you perfect prompt engineering / figure out how to be as explicit and precise as possible about your requirements and how the code should perform.
Sooo is the AI revolution going to actually make people write good documentation and wikis?? 😅😅

It turns out #PHP is as far away from my familiar safety blanket of #Python as you can get 😅.
I am tracking and notes & journey so far (probably soon to be a blog)
My "WTH is that" list so far: npm, vue, bun, brew, blade, react, mix, vite, herd, inertia, sail, tailwind, nginx.

Second day at #laracon EU and I have to say, the community here is so lovely and exciting that it made me want to attempt to learn PHP!
And that's something since in all my years of programming so far I never once got tempted to touch #javascript.
I'll call that a big #laravel win!

Quick dinner in the uni campus canteen: on one hand - awesome healthy cheap food. However - you have to listen to someone loudly ponder if nietzsche’s philosophy is compatible with the values of Christianity; and mansplain the moral of the great Gatsby all within 30 seconds. Gen Z be wildin

Had to turn this into a blog write-up - using Elasticsearch to dive into my Oura sleep data and generate my sleep score in just a few lines!
Analyzing my Oura sleep score - is it AI or just math?
Today I dove into my activity tracker data; specifically, the sleep score that Oura calculates daily....

The intuition/assumption about it is pretty simple - more deep sleep and lower heart rate correlate with better scores. Is it that simple?
Let's take a look in a quick data science experiment
