Burry’s been wrong a few times since 2008… but is he really just a one hit wonder? Maybe this move is his big come back? www.cnn.com/2025/11/05/b...

Very cool. And lots of new things to read up more about…

🤣

I often tell people about the differences of operating at various levels of the stack. Typically, the lower you go down the stack, the slower everything goes. Development is slower, ramping to production is slower, stabilization is slower, but also decommissioning things is slower.

How not to roll out AI: a YouTube case study Recently (hard to say when, it was probably a gradual roll out anyway), YouTube began dubbing certain videos with a voiceover in the viewer’s language (presumably based on OS settings). So what’s wrong? 🧵

Pro tip: to get your PRs shipped faster, and save your teammates’ time, re-read your code, and only submit PRs in a state you wish they were in when you review them yourself 🤝

Why is it that every time I want to do something simple, I end up needing to fix some Javascript and then it’s no longer simple 🥲 ?

💯 This is exactly the reason we should have all the engineers on the pager. It doesn't matter if you are staff/principal. Need to be on-call.

Trust those who carry the pager. That’s how I summed up the work of improving reliability in a discussion today. Conducting postmortems after incidents is a great ritual but, like any other process, it can be used either effectively or not.

Good discussion on ParadeDB use cases, search patterns, and reranking.

This is a great in-depth discussion on CDC from two actual practitioners.

This looks interesting. I know the intent is to attach it to production servers, but how about also attaching it to CI? Given a sufficiently comprehensive integration test suite, it could potentially yield much of the same benefits even pre-prod.

More blogging! I don't want AI agents controlling my laptop. Not because that's not useful, but because it's incredibly hard (impossible?) to do securely: sophiebits.com/2025/09/09/a...

If you want to get started reading academic papers, but can’t ever seem to get through one, then let me throw you this underhand toss! I’m sure you can finish reading this one, and then you’ll be well on your way to read more!

Most software is like a banana. Postgres is pretty singular.

Interesting article. A bit slow-going at first, though it is a useful intro or recap for folks unfamiliar with relational data, normal form, etc. The 3rd section is fine though somewhat obvious. The 4th section is really where it shines. I wish more document DB users read it.

Been thinking about GenAI and its use cases… IMHO, It’s appropriate for: - Taking any skill from incompetent to mediocre. - Getting some result without learning how to get it done. And vice versa for what it’s not good for.

New functionality, new video! Watch it to learn about: Facet Counting in Venice youtu.be/gDBFBgxRqSk

I'm preparing some documentation on techniques for merging batch and real-time data, where I'll explore various concepts that have emerged over the past 15 years.

And I’m sure there are more instances out there… no way that we built this three times at LinkedIn (and without really consulting each other much, BTW) and (at least) once at Pinterest, but nowhere else. My goal in naming it the "Hybrid Store Design Pattern" is so that we can finally talk about it.

Yes… it popped up in several systems over the last decade… @venicedb.org implemented it around 2017 (some ~5 years before getting open sourced). Other @linkedin.com proprietary systems (Search, Graph) also implemented it. And Pinterest’s proprietary KV Store system as well. Any others?

What is HyBRID? HyBRID is a recursive backronym used as a mnemonic device to remember the purpose of the Hybrid Store Design Pattern. It means: Hybrid Batch/Real-time Ingested Data.

If you’d like to learn more, this talk provides an in-depth explanation of the Hybrid Store Design Pattern: youtu.be/hc0pgvnr3fQ

Catch the replay for the latest #VeniceDB talk! In it, you will learn more about derived data, the related design patterns coming from the industry over the past 15 years, and how Venice's architecture keeps pushing the boundaries in that space! youtu.be/hc0pgvnr3fQ

I posted about the Hybrid Store design pattern last week and mentioned that @venicedb.org is an open source system that implements it, but that's not the only one!

Have you come across the Hybrid Store design pattern in your work? Please let me know if you did, and point me to any existing systems you know of which do this. I would be curious to compare and contrast.

I think it was a not very well guarded secret… but LinkedIn’s stream team will finally talk publicly about their Kafka rewrite, many years in the making, called North Guard, as well as their abstraction on top of Kafka + NG, called Xinfra. Sign up here to hear about it: meetu.ps/e/NWkXx/466N...

@notion.com, the new translation banner popping up at the top of pages is a huge bother. I don’t see a setting to disable it. Can you at least not make it a modal? It is a horrendous UX needing to appease the banner in order for anything to work on the page. Thanks 🙏

"The most performant code is the one that doesn't run at all." - Hisham, my mentor in my first job out of college.

Scaling and optimizing software is oftentimes not about advanced data structures nor distributed systems concept… it is much more pedestrian than that. Yesterday we took a profiling of a @venicedb.org server under high load, and discovered that…

There are two kinds of players in the Chiefs… Worthy, and unworthy.

The Coupling Cost of Leverage 🧵 This is a summary of a recent discussion about making some system A leverage some other system B. The new system B would replace some functionality which system A already had.

It just dawned on me that "facet counting" does not seem to be expressible in SQL. If we're interested in just a single facet, then this will do the job: SELECT f, COUNT(f) FROM t GROUP BY f; But if you want multiple facets to be counted, you can't really. Unless you do horrible self joins, maybe?

@notion.com, the search when linking pages seems pretty bad these days… somehow it does some "fuzzy matching" of a bunch of low relevance content (which is mildly annoying but whatever, fine…). The big issue is that unless I exactly match the case it doesn’t give me the page I want.

Hack Week was exhilarating. And finally over 😮‍💨😅 We built Duck Vinci! It enables loading @venicedb.org data into @duckdb.org! There are still several details to clean up, but we did use it successfully for the first time yesterday! Now I gotta shop it around to conferences 😂 … any suggestions 😁 ?

@chris.blue, you who knows everyone around here, are there any @duckdb.org maintainers on BS? Asking for a friend 😏 …

For the last several years now, I’ve been thinking that "single-planet software development" is the easy mode.

@notion.com, I have a feature request: Can you please provide an option to order the templates alphabetically? (Or just order them that way without options) I have some tables with lots of templates and it’s kind of a mess finding the right one 😅

My cardiovascular age is 5 years older than my chronological age according to my #Withings scale, but 4 years younger according to my #Oura ring. Presumably, both come to their conclusions in very different ways. What does this 9 years gap mean (if anything)?
