Another day another query language. Querying JSON with JSON query language, making the queries look like JSON arrays.
Might make sense, if all you have is JSON. The question is, if that is the right way of querying or just a backing syntax for an UI editor.
oxdraw - diagrams as code using mermaid but with adding the ability for exact positioning/coloring.
Nice idea, also there is typst integration.
Super interesting post about fly.io state management software.Not a big consensus driven distributed system or centralized, but using SWIM and sqlite with CRDTs. Great to learn to see such design decisions play out on such a big network.

How fast is java? Teaching an old dog new tricks
Nice blog post about Java Vector API to improve rendering using SIMD.
Homerow - Keyboard shortcuts for every button in macOS
successor to vimac, bringing vimium to osx. Is anyone using this? What is the difference to shortcat?
Achievement unlocked: Added a cover slide using a terminal with figlet to my no-slides #elasticon presentation showing ES|QL to look into three years of solar data.
A part of the demo has also been written down in a blog post. See spinscale.de/posts/2025-1...
🛠️ If your team has issues to work through:
We do an exercise at offsites called Elephants, Tigers & Paper Tigers.
- Elephants are things that the group isn’t talking about but needs to
- Tigers are things threatening the team, risks
- Paper tigers are things that seem like risks, but aren’t
Introducing Chronos-2: From univariate to universal forecasting
Reads like a major upgrade to the existing model.
Munich friends! I'll be in Munich for ElasticON Munich on Thursday.
If you want to meet spontaneously on Wednesday noon/afternoon, let's have a coffee somewhere!
How We Saved $500,000 Per Year by Rolling Our Own “S3”
Interesting very specific video processing use-case, where adapting to the actual workflow made more sense economically than using existing AWS infrastructure.
Katakate - Secure sandboxed compute for AI agents and workloads
Self-hosted infra for lightweight VM sandboxes to safely execute untrusted code. Uses kata containers and firecracker (with jailer). Hadn't heard of kata containers before.
FeOS is a revolutionary init system for Linux, designed specifically for hypervisors and servers that run containers.

Javelit is a Java lightning fast data app development framework, inspired by Streamlit
As a fan of streamlit and the way of prototyping small apps fast or having great demos, this sounds intriguing, and I'll test it as soon as I have a use-case.
Probably a decade late, but I finally started setting up neovim with a bit more effort.
Using noise, telescope, checkmate for todos. Also added a gpg plugin, so that I encrypt files and share via dotfiles repo, while only being able to encrypt on personal systems.
Other plugin recommendations?
Danube: a lightweight, cloud‑native messaging/pub-sub platform built in Rust
Storing data in object storage, while using a WAL to keep latencies low. etcd is used for metadata storage. Uses Opendal to write to different object storages.
SierraDB: A Distributed Event Store Built in Rust
Uses the redis protocol for communication. Neat trick to not need to support any clients out of the box - or at least skip the connection handling part, while having custom commands.
Performance Improvements in JDK 25
TLDR; always upgrade, free performance and auto vectorization
The AI-collapse pre-mortem
Interesting piece about splitting the hype from the underlying technology and the generation it is expanding in. "... a collapsing economic bubble is not a useful data point about where this technology will end up."
Cloudflare sandbox SDK
Couple of interesting features like code interpreter, allowing to run jupyter like snippets in a secure sandbox. Support for quickly doing git checkouts to support CI. Also allows for custom base docker images. Based on cloudflare containers
They gave an interesting talk at FOSDEM last year: archive.fosdem.org/2024/schedul...

Garage - an open-source distributed object storage service tailored for self-hosting
S3 compatible data store, single binary, written in Rust, geo based replication, supposed to be faster than Minio. Not seen this so far, anyone running this in prod?
dysk - A CLI utility to get information on filesystems, like df but better
Extending df: adds better formatting via table and colors to a CLI tool, looks instantly a lot more useful than df. Wish existing tools would not be considered 'finished' sometimes, but extended.
CPU Cache-Friendly Data Structures in Go: 10x Speed with Same Algorithm
Nice examples for Go how to write CPU friendly code by not thrashing cache lines.

I used sea animals i.e. needlefish, orca, whaleshark… next iteration will be small sea animals I guess :-)

Why TigerBeetle is the most interesting database in the world
An article by an invested VC, but highly technical, with a lot of links to youtube talks and blog posts. Wondering if this is preparing for the series B here. Time will tell.
hygg - Minimalistic Vim-like TUI document reader
Uses pandoc for document conversion, and then puts a TUI around the output neatly formatted, allowing easy selection, with vim keybindings.
rioterm - a hardware-accelerated GPU terminal emulator focusing to run in desktops and browsers
Never heard of this one despite 5k github stars. Written in Rust just like wezterm, but also compiles to WASM (soon), and a focus on speed.
TIL there is GTFS - The general transit feed specification
A specification for dynamic traffic data (delays, broken escalators, reroutes, everything around stations), in protobuf and heavily in production use - at least in Germany. You find realtime feeds, making it nice demo data.
