Haters gonna hate but I love wild data. It just doesn't hit the same after all the little human footprints are scrubbed clean #databs

Hit my goal early this year 🌟 (and made a chart of course #databs)

Ending a busy weekend with solving days 5, 6 and 7 in one sitting. Only 5 days left of unconventional SQL fun 😊

When you picked the right programming language for day 5 😄

Day 4 was definitely a lot harder then the first three, but happy to report I eventually figured out how to do it with SQL 😊 #AdventOfCode #databs adventofcode.com/2025/day/4

Day 3... Strap in for some recursive SQL 🔋🔋🔋🔋🔋🔋🔋🔋🔋🔋🔋🔋 adventofcode.com/2025/day/3

Should I use SQL for Advent of Code? ...probably not But can I solve all puzzles using SQL? ...again, probably not But will I try anyway? ... definitely yes 🦆 #databs github.com/LienBosmans/...

If you're not making yourself the hero of the internal documentation you're writing, what's even the point? #databs

You are faced with two data sources. One mostly tells the truth, the other sometimes lies. They never answer your questions at the same time. A small mob of stake-holders is demanding a fresh and perfectly trustworthy report of events. In short, you are utterly and completely fucked. Luckily, ...

I'm currently in the muddy part of getting to know a new dataset... and a new API... and a new query language... wish me luck #databs! At least the documentation seems pretty complete 😊

New PyStack't documentation site is live! lienbosmans.github.io/pystackt/ #pystackt #opensource #OCED #processmining

What's awesome about building open source is that you don't have to worry about sales prospects. For example, using your favourite animal stacking poo cubes as the logo for a data preparation tool, is a totally valid option. #databs

How's your side project going? #databs #opensource

Vendor demos be like "give us money because AI goes brrrrr"

📢 PyStack't is now open for contributions! (To be honest, it always was, but now there is a contributing guide to make it more obvious and to help you get started.) So, for anyone out there working on object-centric process mining, you're invited to 🧵 github.com/LienBosmans/...

This app allows me to relive my insect nerd childhood days and I'm loving it 😍 play.google.com/store/apps/d...

"The translation from a business-oriented request into a data-oriented request should be on the data professional, not the stakeholder." and plenty more wisdom nuggets to be found here ⬇️

If you're not sure how to interpret horizon plots, this gif is a nice, quick explainer: bernatgel.github.io/karyoploter_...

New PyStack't release! This one is called v0.1.0 and includes 🧵 github.com/LienBosmans/... #databs

It's funny how the answer to "What is the problem with this function!?" is almost always "it's me, I am the problem" #rstats #databs

Talking about a beautiful branch of mathematics :) #mathematics #stem

When you're 24 hours into an +- 30 hours stress-test data extraction and the GitHub API goes down, so it fails with a MaxRetryError 😭

@twisteddoodles.bsky.social didn't share this one here yet... so I'm sharing a screen grab because it made me giggle out loud in this conference season #databs

New version of PyStack't is now live! ◝(ᵔᵕᵔ)◜ No new functionality this time, but a small fix that makes the output of ᴇxᴘᴏʀᴛ_ᴛᴏ_ᴏᴄᴇʟ2() compatible with #OCPQ. Now you can use them together to discover the process behind any open-source GitHub repo 🔥 #processmining #ocpm

My cartoon for this week’s @newscientist.com

was just reminded of how much I love the debugging manifesto poster that Inner Loop Press designed for Wizard Zines, you can get it for $20 US + shipping here: store.wizardzines.com/products/pos... I'm SO delighted with how it turned out (also for more of Inner Loop's work: www.innerloop.press)

Today we're launching DuckLake, an integrated data lake and catalog format powered by SQL. DuckLake unlocks next-generation data warehousing where compute is local, consistency central, and storage scales till infinity. ⁠ducklake is an open standard and we implemented it in the "ducklake" extension.

It always amazes me how much effort goes into making something "simple".

To all the "honored and humbled" people in my LinkedIn feed today: are you okay or is this a secret cry for help that you were recruited by your warlord to go on a suicide mission after you offended their firstborn?

So, I've been super interested in moving away from single page JavaScript apps recently. And was reminded of this. So funny. Read it someplace where you can LoL justfuckingusehtml.com

You can now try out the "something fun that might even be interesting" thing I started building 3 weeks ago! PyStack't is my hobby project where I try to bring some data engineering best practices to object-centric process mining.

PyStack't v0.0.3 is now live! For all the curious #databs minds that want to browse through the event data of their favorite open-source GitHub projects... Happy exploring! 😘 For the #processmining community desperate for real-life OCED data... Happy researching! 😘 pypi.org/project/pyst...

PyStack't is getting some cool new functionality soon! #databs #processmining github.com/LienBosmans/...

My graph visualization project train arrived at station "nice from afar, messed up from up close", which holds true for real processes too so I think it's on the right track #databs

Okay friends. Today I am writing a thread that I have been thinking about for a long, long, long time. It's really, really important. It is also very heavy. Cis people, read this. Look with your eyes open at it. Sit with it. Feel it. Absorb it. Trans people, take care. This is about history. 🧵

Building some cool shit! #databs Or at least it will be cool... soon...ish? Let's leave it at "I have good hopes that I will stick long enough with this attempt at creating interactive graph visualizations to create something fun that might even be interesting"

Using AI to make coloring pages for the kids, because how would I otherwise find one of a "twinkling unicorn jumping over a tree stump with star shaped moss"

Sometimes I make art

Work in progress

Today was the day I needed to fix a legacy PowerBI report that broke months ago when we switched query engines #databs

Only dating advice I can give is that in 24/7 manufacturing environment a day often starts at early shift instead of midnight and so you should always clarify that when getting requirements from stakeholders #databs

DuckDB got a local UI. Thanks to our friends at MotherDuck, you can now interact with your DuckDB database through an interactive notebook, running on localhost. Read the announcement blog post at duckdb.org/2025/03/12/d...
