Also made a cute embedding of all their products! datania.github.io/mercadona-ca...

Discovered Mercadona's API and wrote a quick scrapper that will run weekly and dumps everything into JSONs in HuggingFace. Useful to track prices over time, check new arrivals, ... Data. huggingface.co/datasets/dat... Code. github.com/datania/merc...

The team that built CXDB recently published their take on "software factories". Recommended reading as it contains a few cool tricks (e.g. holdout sets, ...). factory.strongdm.ai

Spotted this interesting design/implementation of a self-hosted context store for agents. - Turn DAG - Blob Deduplication / Content Addresses Storage - BLAKE3 - Dynamic types, visual debugging, ... github.com/strongdm/cxdb

If you are curious what a frontier coding agent feels like to use, and don't want to pay or put in a credit card to try it out, here you go: ampcode.com/code/AMP-BSK...

Why is the AI revolution happening on the command line first? Because the terminal is still the most open-ended general-purpose computing platform available. Unix Philosophy is All You Need.

Yeah, like please invest that effort into turning your app state into local Markdown and JSON (or SQLite) files so I can use my good AI tools to work with it

Want to re-raise this banger of an article, which really helped frame the differences between atproto and bluesky, and turned me into a convert for atproto bsky.app/profile/dana...

Best clanker out there!

TIL you can install Python tools without uv or Python with a single curl command! uvx.sh Useful for Docker, CI pipelines, or anywhere you don't want to mess with the Python installation or venvs!

It's amazing how many declarative data stacks have emerged since I started this topic. I just updated the list with the latest open-source once. Do you know of any others? Happy to append to the list. Check out the full breakdown at .

someone from github should write a check to tangled and merge it into main

Realized I haven't used Jupyter Notebooks in a good while. Codex/CC with PEP 723 inline metadata knowledge has been doing it for myself.

Data visualization: Every human language, from modern day back through protolanguage to a hypothetical common origin. Accurate, sourced, possibly complete. Includes sign language! Tap or mouse over to highlight individual branches; many also have more info. 🛌 this project has been a beast

Weekend thoughts on Gas Town, Beads, slop AI browsers, and AI-generated PRs flooding overwhelmed maintainers. I don't think we're ready for our new powers we're wielding. lucumr.pocoo.org/2026/1/18/ag...

Shared an assortment of personal workflows I've found useful when working with "agents" across work, data, and research. In 2025, I had ton of fun tinkering with this new way of working. I'm sure they won't last until next year. Meanwhile, hope they're helpful! davidgasquez.com/useful-agent...

Updated the design of my personal website and I love it! davidgasquez.com/handbook

At the risk of starting the flame war to end all flame wars... Modern LLMs (GPT-5.1, Claude 4.5, Gemini 3) produce excellent code and can be a significant productivity boost to software engineers who take the time to learn how to effectively apply them - especially if used with coding agent tools

Been using Codex CLI for some tasks like tagging and entity extraction. Turns out tasks get way easier when you force more small, local decisions without global context and then a few "aggregations" on top. Accidentally rediscovered MapReduce again! 😅

the two types of organizations: spreadsheets and cults

Awesome job with this new series @jed.co! Love the topics and conversations.

I've been using this pattern to "specialize" Codex for vaguely defined tasks like classification, filtering, soft sorting, ... davidgasquez.com/specializing... Made more than 10,000 invocations so far (reusing my ChatGPT subsciption) and am really happy with the pattern!

I've been curating some "Agentic Coding" tips and tricks for a while. Check them out if you're into that! davidgasquez.com/handbook/art...

I've become one of those people who run multiple coding agents at once - here are my notes on embracing the parallel coding agent lifestyle simonwillison.net/2025/Oct/5/p...

When you try to predict about the impact of AI tools on software engineering - a great analogy I heard from @simonwillison.net is to look at the impact of smartphones (+ the amazing cameras they have) on filmmaking. Noticed that those able to shoot pro films using a smartphone are... pros?

I personally see collapse as an inevitability for every individual institution. Nothing lasts forever. The smart way to build systems is to enable reforms so that they can adjust to reality without destroying what works in the process. This is pretty baked into the philosophy of Bluesky

if only there were a decentralized, immutable, and versioned way to fix this!

I wrote up some thoughts about why we’re seeing a gap in AI tool use among different types of developers narphorium.com/blog/top-dow... 1/4

Is there a name for the pattern where you try building the same thing (feature, project, ...) a bunch of times with different agents to get a sense of the implementation design space? I usually run things at least 2 or 3 times until I "feel" what is the way I want it to be built.

Both Evidence and Observable Framework seem to be slowing down in development. - github.com/observablehq... - github.com/evidence-dev... Not sure why. Anyone has any context or ideas?

My dotfiles repository is now mirrored on @tangled.sh too! tangled.sh/@davidgasque...

Spent some time refining the approach and benchmarking it. Just published a blog post about the core idea. Can a bunch of LLM Agents be used to rank an arbitrary set of items in a consistent way? 🤖 davidgasquez.com/ranking-with...

Wrote a post about a small pattern I've been using for a while. Replacing chunks of bash scripts with `llm` or inline Claude Code calls. For example, for data cleaning/structuring. davidgasquez.com/scrappy-data...

usually the baseline is “nothing” so the right heuristic is usually not “is it ideal” but rather “is it better than nothing?”

Are there any benchmarks/evals that track model performance over time? I've heard things like Claude/Cursor getting dummier over time (haven't noticed much myself) and am wondering if there is some data to back this.

New data oriented file format just dropped. FastLanes, "like Parquet, but with 40% better compression and 40× faster decoding". 👀 Seems it can exploit correlations between columns and have fully SIMD friendly encodings to help with vectorization. github.com/cwida/FastLa...

Asked Claude to move my handbook notes from Obsdian to my Astro website. Very happy with the results! davidgasquez.com/handbook/dat... I'll keep the Obsidian Publish version around while I work on making it look as good.

Will 2025 finally be the year of the Linux desktop? Really cool to see folks like @mitsuhiko.at or @ssp.sh trying out Arch, Hyprland, and other modern Linux stuff thanks to Omarchy! More people, more polished experience, more dotfiles to learn from!

The end dataset also serves as a much smoother API! - No key required - Batch export friendly - Explorable in the browser

Spent some time this weekend playing with AEMET's APIs and wrote a small post sharing what I learned and how I approached the project. davidgasquez.com/exporting-ae... I'm really enjoying working on these small, one-off projects as a way to experiment with different techniques. 🧪

Updated linkweaver (custom notes & research helper) with a couple of new tricks. 1. Saves the URL content locally 2. Accepts any command to preprocess the generated Markdown. E.g: `llm "Clean the following Markdown"`. github.com/davidgasquez... Want to try it? `uvx linkweaver` and enjoy! 😀

One of the best things I'm using LLMs for is to make lots of small UNIX style CLIs! 🤩 I'm talking about simple/silly things like listing all the unique links in a bunch of markdown notes (`xl *.md`). What a time!

Seeing a new long form video from Michael (Vsauce) after so long made my day! 🤩 www.youtube.com/watch?v=xHd4...

I think all my projects now have a very simple CLAUDE.md file that imports the README, CONTRIBUTING, and, Makefile. Great setup for humans and for LLMs! davidgasquez.com/llm-friendly...

🏖️ Summer is around the corner, and I thought of making a summer special in the form of a Postcard Series. This edition holds unique & insightful links to read, listen to, or enjoy while chilling at the pool or when lying on the beach, presented as 14 postcards with 3 links and a description each.

Now making the agents in the tool chose the final name of the tool using the tool itself. 😜 github.com/davidgasquez...

One thing I took from this experiment is that now, almost all my notes have a few <resource> XML tags that are very helpful when "talking" with the note.
