Video is just the beginning

[Spiral @SpiralDB]

Machines Don't Press Play

For decades, video's been optimized for one consumer: a human pressing play

But when training a world model, the consumer is a machine, not a human

Check out @ngates_ 's deep dive on training with videos and the infra opps to help you move faster

You choose the right storage and the graphs go down... #modernfileformats #vortex

[Alfonso Subiotto ❄️ @asubiotto]

We've been working on a major schema migration at @PolarSignalsIO that has unlocked some pretty wild improvements. Apart from a 50% (!!) reduction in storage size thanks to logical compression in @vortexdotdev, there has been a dramatic improvement in query performance.

[Robert Kruszewski @Robert3005]

@GDSTeam I don't think this is how you do http redirect - Location: redirect:/onelogin/there-is-a-problem. But also seems like this is an unhandled error elsewhere allowed to propagate to the user

[Robert Kruszewski @Robert3005]

@mitchellh Have you had the agent try to modify your library code to make the fuzzer happy yet? The objective function might have been underspecified :D

[Robert Kruszewski @Robert3005]

Who would have thought that people have come up with better compression techniques since 2011

[Nicholas Gates @ngates_]

Vortex is BOTH 38% smaller and has 10–25x faster scans than Parquet+ZStd for TPC-H SF10

We implemented BtrBlocks-style cascading compression in Vortex that recursively tries codecs like ALP, FSST, and bit-packing, letting the data pick the best encoding

Finally iceberg is going to support something that came out less than 15 years ago

[Spiral @SpiralDB]

Vortex 🤝 Apache Iceberg

Coming soon!

@vortexdotdev @ApacheIceberg

[Robert Kruszewski @Robert3005]

@mitchellh This is a cool feature, definitely love the ease of creating useful themes. It has surprising behaviour when combined with some appliactions. Vim theme (https://t.co/L1xGyQZOuo) I use ended up being needlessly washed out/pastel like. Also couldn't distinguish accents in fzf.

[Robert Kruszewski @Robert3005]

Has there ever been more anticipated software feature? Absolute product development.

[Mitchell Hashimoto @mitchellh]

Well, it has happened. Ghostty on macOS now has search. This is now in tip releases, I'm certain there's a bunch of polish and bugs to work through over the next months, but more than enough time for it to be rock solid for 1.3 next year. GTK to follow soon. Gobble, gobble. 🦃🦃

[Robert Kruszewski @Robert3005]

Are you keeping your GPUs fed?

[Spiral @SpiralDB]

We're building the data infrastructure that AI actually needs.

Current systems were built for humans reading dashboards. But an H100 can consume 4 million images per second.

The future isn't human-scale. It's machine-scale.

Introducing Spiral: Data 3.0 🌀

You can write Java but also keep it cool

[Spiral @SpiralDB]

Checkout our latest post by @andreweduffy about bridging our Rust code to Java to accelerate Apache Iceberg queries 🏎️

Hey @duolingo how would I have both gotten the friends quest boost and failed the friends quest at the same time? Sounds like someone could use a refresher on transactions and consistency models.

[Robert Kruszewski @Robert3005]

All research papers should use rust as a reference implementation language https://t.co/1RSv0ptALc

[Robert Kruszewski @Robert3005]

We are hosting a meet up. You should come.

[Spiral @SpiralDB]

We are hosting our inaugural London Systems event on March 26th, inspired by the analogous events in NYC & SF.

We will feature talks from Mistral and Spiral, with plenty of time for mingling over drinks and pizza.

RSVP here: https://t.co/gRyNlasYeR

[Robert Kruszewski @Robert3005]

Can we have one file format instead of augmenting Parquet to death?

[Spiral @SpiralDB]

Is your data where it needs to be? We explore the critical design decisions surrounding data layouts when creating file formats. https://t.co/PQiKxWdE5U

[Robert Kruszewski @Robert3005]

Checkout new meetup @SpiralDB is organising. I always thought there's not enough events like these in London

[Adam @adamm_gs]

1/ We (@SpiralDB) are putting together a London systems meetup, to give a chance for (software) engineers to share and discuss their work on the underlying systems and tools that power most of our work - databases, compilers, VMs etc. and we're looking for speakers! >>

[Robert Kruszewski @Robert3005]

Faster file format one pr at a time

[Spiral @SpiralDB]

This Halloween, we wanted to take a moment to reflect on another month of building Vortex in the open

https://t.co/IToL0Bqq5e

[Robert Kruszewski @Robert3005]

Or why you shouldn’t use physical types in data processing apis

[Spiral @SpiralDB]

New blog post from CTO @ngates_ exploring the design of a type system for the Vortex file format

[Robert Kruszewski @Robert3005]

Thanks to @andreweduffy everyone can benefit from FSST compression, not just duckdb.

[Andrew Duffy @andreweduffy]

At @spiraldb, we recently implemented an initial version of FSST for fast, random-access string compression. I wrote a blog post to walk through some of the concepts.

[Nicholas Gates @ngates_]

@criccomini @databricks Are any @databricks open-source projects real?

OSS Unity != DataBricks Unity
OSS Delta != DataBricks Delta
OSS Spark != DataBricks Spark/Photon

[Nicholas Gates @ngates_]

@andrewlamb1111 @peterabcz @LeonardoKuffo @SIGMODConf @cwi_da Beat you to it i'm afraid! https://t.co/fcM4k8acwV
