Just finished v0.1.0 of my personal website!
I used Quarto and GitHub pages to make a personal portfolio website, which also has some guides I've done. I've got some updates to my about (Resume) page and blogs pages. Light and dark mode works! Otherwise, check it out:

I’ve been working on a C-Suite high priority ask recently. About the last 3.5 weeks straight of nothing but this.
Taking a table in Snowflake with ~90 million rows, doing some drastic transformations/reordering of timestamps + metrics based off those and historical performance.

Superman is great, worth it to see in imax, in my opinion.
Gunn definitely has a clear style to his superhero features and it shows (in a great way) with Superman and the film’s aesthetics

Great read, Derek Goat does it again 🫡
It's true that progressives valorize "ugliness." But I think this person doesn't interrogate this position enough and thus lands at the wrong conclusion.
Let me give you my perspective on ugliness. 🧵

Whoever at Microsoft decided to have ‘Chris’ autocomplete as Christmas, in Outlook, why?
It’s a goofy decision and makes me sweat everytime I sign an email 😂

I started a new job and moved a few months ago, so I have new internet. In that time, I’ve had so many Teams problems with video chat. I thought it was just me, but others I work with have the same problems. Anyone else feel like Teams got worse recently?

The discourse on here that bluesky users are mean is funny to me.
All of my interactions are pretty straightforward discussions, maybe that’s the difference between the data folks/nerds (I am a nerd) and the more politically focused people 🤷

There is lots of RFC1918 space out there, yet most people use the same 10 /24 subnets
I ended up having my OOB LAN collide with someone's home network a few weeks ago, and decided to find a new subnet to use that won't collide backed up with actual usage data!

Slight data break for Political Comments:
This has been very public knowledge for over a year. Sometime last spring (IIRC), or maybe even closer to Elon’s book, it came out his boards did not like his ketamine use. He was basically in a k-hole half the time he should have been “working”

New reporting reveals that Elon Musk has been known to heavily abuse drugs:
"Mr. Musk’s drug consumption went well beyond occasional use. He told people he was taking so much ketamine that it was affecting his bladder, a known effect of chronic use. He took Ecstasy."

Random thought, may be very stupid:
If DuckLake uses databases for metadata, and open files for data, wouldn’t this reduce storage across environments (DEV, QA, UAT, PROD)? The only changes would be to metadata, all environments use the same data sources… or do all DBs work like this? #databs

This is genius. If I’m understanding correctly, metadata is handled by a DuckDB compatible SQL database and the actual data is handled by an open file format of your choice.
You can perform familiar SQL queries and DDL, on highly scalable open format data files. Well done! #databs #dataengineering

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.
