Weeknotes: Embeddings, more embeddings and Datasette Cloud
Since my last weeknotes, a flurry of activity. LLM has embeddings support now, and Datasette Cloud has driven some major improvements to the wider Datasette ecosystem.
[... 2,427 words]Introducing datasette-litestream: easy replication for SQLite databases in Datasette. We use Litestream on Datasette Cloud for streaming backups of user data to S3. Alex Garcia extracted out our implementation into a standalone Datasette plugin, which bundles the Litestream Go binary (for the relevant platform) in the package you get when you run “datasette install datasette-litestream”—so now Datasette has a very robust answer to questions about SQLite disaster recovery beyond just the Datasette Cloud platform.
Datasette 1.0a4 and 1.0a5, plus weeknotes
Two new alpha releases of Datasette, plus a keynote at WordCamp, a new LLM release, two new LLM plugins and a flurry of TILs.
[... 2,709 words]Datasette Cloud and the Datasette 1.0 alphas. I sent out the Datasette Newsletter for the first time in quite a while, with updates on Datasette Cloud, the Datasette 1.0 alphas, a note about the security vulnerability in those alphas and a summary of some of my research into combining LLMs with Datasette.
Datasette 1.0 alpha series leaks names of databases and tables to unauthenticated users. I found and fixed a security vulnerability in the Datasette 1.0 alpha series, described in this GitHub security advisory.
The vulnerability allowed unauthenticated users to see the names of the databases and tables in an otherwise private Datasette instance—though not the actual table contents.
The fix is now shipped in Datasette 1.0a4.
The vulnerability affected Datasette Cloud as well, but thankfully I was able to analyze the access logs and confirm that no unauthenticated requests had been made against any of the affected endpoints.
Datasette Cloud, Datasette 1.0a3, llm-mlc and more
Datasette Cloud is now a significant step closer to general availability. The Datasette 1.03 alpha release is out, with a mostly finalized JSON format for 1.0. Plus new plugins for LLM and sqlite-utils and a flurry of things I’ve learned.
[... 1,690 words]Introducing datasette-write-ui: a Datasette plugin for editing, inserting, and deleting rows. Alex García is working with me on Datasette Cloud for the next few months, graciously sponsored by Fly. We will be working in public, releasing open source code and documenting how to build a multi-tenant SaaS product using Fly Machines.
Alex’s first project is datasette-write-ui, a plugin that finally lets you directly edit data stored inside Datasette. Alex wrote about the plugin on our new Datasette Cloud blog.
Welcome to Datasette Cloud. We launched the Datasette Cloud blog today! The SaaS hosted version of Datasette is ready to start onboarding more users—this post describes what it can do so far and hints at what’s planned to come next.
Dependency Management Data (via) This is a really neat CLI tool by Jamie Tanna, built using Go and SQLite but with a feature that embeds a Datasette instance (literally shelling out to start the process running from within the Go application) to provide an interface for browsing the resulting database.
It addresses the challenge of keeping track of the dependencies used across an organization, by gathering them into a SQLite database from a variety of different sources—currently Dependabot, Renovate and some custom AWS tooling.
The “Example” page links to a live Datasette instance and includes video demos of the tool in action.
Datasette 1.0a3. A new Datasette alpha release. This one previews the new default JSON API design that’s coming in 1.0—the single most significant change in the 1.0 milestone, since I plan to keep that API stable for many years to come.
Weeknotes: Plugins for LLM, sqlite-utils and Datasette
The principle theme for the past few weeks has been plugins.
[... 1,203 words]Weeknotes: Self-hosted language models with LLM plugins, a new Datasette tutorial, a dozen package releases, a dozen TILs
A lot of stuff to cover from the past two and a half weeks.
[... 1,742 words]Data analysis with SQLite and Python. I turned my 2hr45m workshop from PyCon into the latest official tutorial on the Datasette website. It includes an extensive handout which should be useful independently of the video itself.
Weeknotes: Parquet in Datasette Lite, various talks, more LLM hacking
I’ve fallen a bit behind on my weeknotes. Here’s a catchup for the last few weeks.
[... 769 words]Vector Search. Amjith Ramanujam provides a very thorough tutorial on implementing vector similarity search using SentenceTransformers embeddings (all-MiniLM-L6-v2) executed using sqlite-utils, then served via datasette-sqlite-vss and deployed using Fly.
Exploration de données avec Datasette. One of the great delights of open source development is seeing people run workshops on your project, even more so when they’re in a language other than English! Romain Clement presented this French workshop for the Python Grenoble meetup on 25th May 2023, using GitHub Codespaces as the environment. It’s pretty comprehensive, including a 300,000+ row example table which illustrates Datasette plugins such as datasette-cluster-map and datasette-leaflet-geojson.
MMS Language Coverage in Datasette Lite. I converted the HTML table of 4,021 languages supported by Meta’s new Massively Multilingual Speech models to newline-delimited JSON and loaded it into Datasette Lite. Faceting by Language Family is particularly interesting—the top five families represented are Niger-Congo with 1,019, Austronesian with 609, Sino-Tibetan with 288, Indo-European with 278 and Afro-Asiatic with 222.
Big Opportunities in Small Data
I gave an invited keynote at Citus Con 2023, the PostgreSQL conference. Below is the abstract, video, slides and links from the presentation.
[... 385 words]Data analysis with SQLite and Python for PyCon 2023
I’m at PyCon 2023 in Salt Lake City this week.
[... 347 words]What’s in the RedPajama-Data-1T LLM training set
RedPajama is “a project to create leading open-source models, starts by reproducing LLaMA training dataset of over 1.2 trillion tokens”. It’s a collaboration between Together, Ontocord.ai, ETH DS3Lab, Stanford CRFM, Hazy Research, and MILA Québec AI Institute.
[... 1,077 words]sqlite-history: tracking changes to SQLite tables using triggers (also weeknotes)
In between blogging about ChatGPT rhetoric, micro-benchmarking with ChatGPT Code Interpreter and Why prompt injection is an even bigger problem now I managed to ship the beginnings of a new project: sqlite-history.
[... 1,680 words]GitHub Accelerator: our first cohort. I’m participating in the first cohort of GitHub’s new open source accelerator program, with Datasette (and related projects). It’s a 10 week program with 20 projects working together “with an end goal of building durable streams of funding for their work”.
Weeknotes: A new llm CLI tool, plus automating my weeknotes and newsletter
I started publishing weeknotes in 2019 partly as a way to hold myself accountable but mainly as a way to encourage myself to write more.
[... 830 words]Semi-automating a Substack newsletter with an Observable notebook
I recently started sending out a weekly-ish email newsletter consisting of content from my blog. I’ve mostly automated that, using an Observable Notebook to generate the HTML. Here’s how that system works.
[... 2,520 words]I built a ChatGPT plugin to answer questions about data hosted in Datasette
Yesterday OpenAI announced support for ChatGPT plugins. It’s now possible to teach ChatGPT how to make calls out to external APIs and use the responses to help generate further answers in the current conversation.
[... 1,801 words]Weeknotes: AI won’t slow down, a new newsletter and a huge Datasette refactor
I’m a few weeks behind on my weeknotes, but it’s not through lack of attention to my blog. AI just keeps getting weirder and more interesting.
[... 1,255 words]Datasette: Gather feedback on new ?_extra= design. I just landed the single biggest backwards-incompatible change to Datasette ever, in preparation for the 1.0 release. It’s a change to the default JSON format from the Datasette API—the new format is much slimmer, and can be expanded using a new ?_extra= query string parameter. I’m desperately keen on getting feedback on this change! This issues has more details and a call for feedback.
Using Datasette in GitHub Codespaces. A new Datasette tutorial showing how it can be run inside GitHub Codespaces—GitHub’s browser-based development environments—in order to explore and analyze data. I’ve been using Codespaces to run tutorials recently and it’s absolutely fantastic, because it puts every tutorial attendee on a level playing field with respect to their development environments.
Analytics: Hacker News v.s. a tweet from Elon Musk
My post Bing: “I will not harm you unless you harm me first” really took off.
[... 817 words]Introducing sqlite-vss: A SQLite Extension for Vector Search (via) This latest SQLite extension from Alex Garcia is possibly his best yet: it adds FAISS-powered vector similarity search directly to SQLite, enabling fast KNN similarity lookups against a virtual table that feels a lot like SQLite’s own built-in full text search feature. This write-up includes interactive demos using Datasette called from an Observable notebook, running similarity searches against an index of 200,000 news headlines and summaries in less than 50ms.
