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

LINK ROT: 38% webpages that existed in 2013 were no longer available 10 years later.
Even among pages that existed in 2021, 22% no longer accessible just two years later. This is often because individual page was deleted or removed on otherwise functional website.
Many implications for knowledge 🧪

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.

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.

While working on a small analysis over highly unstructed data at work, I came up with a very hacky but effective and cheap way to clean and process messy data. There is almost no code involved. The main downside is that requires a Claude Code subscription for it to be cost effective!

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.

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! 😀

![❯ uvx linkweaver --help
usage: linkweaver [-h] [--list-links] [--xml-cat] [-x COMMAND] [-v] [--retries N] [-q] [--dry-run] [--no-color] [-f] [input_files ...]
Extract URLs from markdown files and save each link as individual markdown files in resource folders.
By default, existing files are skipped to save time and bandwidth.
positional arguments:
input_files One or more markdown files to process
options:
-h, --help show this help message and exit
--list-links, -l List all unique URLs found in the files (no downloading)
--xml-cat Concatenate files with their resource folders in XML structure
-x, --exec COMMAND Execute a shell command on the markdown output before saving (e.g., 'llm -t mdclean')
-v, --verbose Enable verbose output with detailed progress information
--retries N Number of retry attempts for failed URL fetches (default: 3)
-q, --quiet Minimize output (opposite of verbose, but still show errors/warnings)
--dry-run Show what would be done without actually doing it
--no-color Disable colored output
-f, --force Force redownload of files even if they already exist
Examples:
linkweaver notes.md # Process file, skip existing resources
linkweaver --force notes.md # Force redownload all resources
linkweaver --list-links notes.md # List all URLs found
linkweaver --xml-cat notes.md # Concatenate with resources
linkweaver -x 'llm -t clean' notes.md # Process with custom command
linkweaver --retries 5 notes.md # Use 5 retry attempts for failed URLs
linkweaver --quiet --dry-run notes.md # Preview actions quietly
linkweaver -q -v notes.md # Quiet mode overrides verbose
linkweaver --no-color notes.md # Disable colored output
Common workflows:
linkweaver --list-links *.md | head -10 # Preview first 10 URLs](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:4z5i7njrld66ew36htufcwry/bafkreibaegi4bgm4cwvnrbe3iqho4lpjlbmzkc4oddwimts74czkishbiq@jpeg)

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`).
