llm-claude-3. I built a new plugin for LLM—my command-line tool and Python library for interacting with Large Language Models—which adds support for the new Claude 3 models from Anthropic. # 4th March 2024, 6:46 pm
datasette-studio. I’ve been thinking for a while that it might be interesting to have a version of Datasette that comes bundled with a set of useful plugins, aimed at expanding Datasette’s default functionality to cover things like importing data and editing schemas.
This morning I built the very first experimental preview of what that could look like. Install it using pipx:
pipx install datasette-studio
I recommend pipx because it will ensure datasette-studio gets its own isolated environment, independent of any other Datasette installations you might have.
Now running “datasette-studio” instead of “datasette” will get you the version with the bundled plugins.
The implementation of this is fun—it’s a single pyproject.toml file defining the dependencies and setting up the datasette-studio CLI hook, which is enough to provide the full set of functionality.
Is this a good idea? I don’t know yet, but it’s certainly an interesting initial experiment. # 18th February 2024, 8:38 pm
Publish Python packages to PyPI with a python-lib cookiecutter template and GitHub Actions
I use cookiecutter to start almost all of my Python projects. It helps me quickly generate a skeleton of a project with my preferred directory structure and configured tools.
[... 686 words]Symbex: search Python code for functions and classes, then pipe them into a LLM
I just released a new Python CLI tool called Symbex. It’s a search tool, loosely inspired by ripgrep, which lets you search Python code for functions and classes by name or wildcard, then see just the source code of those matching entities.
[... 1183 words]Trogon (via) The latest project from the Textualize/Rich crew, Trogon provides a Python decorator—@tui—which, when applied to a Click CLI application, adds a new interactive TUI mode which introspects the available subcommands and their options and creates a full Text User Interface—with keyboard and mouse support—for assembling invocations of those various commands.
I just shipped sqlite-utils 3.32 with support for this—it uses an optional dependency, so you’ll need to run “sqlite-utils install trogon” and then “sqlite-utils tui” to try it out. # 21st May 2023, 9:39 pm
Datasette Lite: a server-side Python web application running in a browser
Datasette Lite is a new way to run Datasette: entirely in a browser, taking advantage of the incredible Pyodide project which provides Python compiled to WebAssembly plus a whole suite of useful extras.
[... 4800 words]Automatically opening issues when tracked file content changes
I figured out a GitHub Actions pattern to keep track of a file published somewhere on the internet and automatically open a new repository issue any time the contents of that file changes.
[... 1211 words]s3-credentials: a tool for creating credentials for S3 buckets
I’ve built a command-line tool called s3-credentials to solve a problem that’s been frustrating me for ages: how to quickly and easily create AWS credentials (an access key and secret key) that have permission to read or write from just a single S3 bucket.
[... 1618 words]Weeknotes: datasette-export-notebook, PyInstaller packaged Datasette, CBSAs
What a terrible week. I’ve found it hard to concentrate on anything substantial. In a mostly futile attempt to distract myself from doomscrolling I’ve mainly been building some experimental output plugins, fiddling with PyInstaller and messing around with shapefiles.
[... 732 words]datasette-ripgrep: deploy a regular expression search engine for your source code
This week I built datasette-ripgrep—a web application for running regular expression searches against source code, built on top of the amazing ripgrep command-line tool.
[... 1362 words]click-app. While working on sqlite-generate today I built a cookiecutter template for building the skeleton for Click command-line utilities. It’s based on datasette-plugin so it automatically sets up GitHub Actions for running tests and deploying packages to PyPI. # 23rd June 2020, 2:21 am
Weeknotes: Covid-19, First Python Notebook, more Dogsheep, Tailscale
My covid-19.datasettes.com project publishes information on COVID-19 cases around the world. The project started out using data from Johns Hopkins CSSE, but last week the New York Times started publishing high quality USA county- and state-level daily numbers to their own repository. Here’s the change that added the NY Times data.
[... 993 words]How to cheat at unit tests with pytest and Black
I’ve been making a lot of progress on Datasette Cloud this week. As an application that provides private hosted Datasette instances (initially targeted at data journalists and newsrooms) the majority of the code I’ve written deals with permissions: allowing people to form teams, invite team members, promote and demote team administrators and suchlike.
[... 933 words]Datasette 0.31. Released today: this version adds compatibility with Python 3.8 and breaks compatibility with Python 3.5. Since Glitch support Python 3.7.3 now I decided I could finally give up on 3.5. This means Datasette can use f-strings now, but more importantly it opens up the opportunity to start taking advantage of Starlette, which makes all kinds of interesting new ASGI-based plugins much easier to build. # 12th November 2019, 6:11 am
json-flatten. A little Python library I wrote that attempts to flatten a JSON object into a set of key/value pairs suitable for transmitting in a query string or using to construct an HTML form. I first wrote this back in 2015 as a Gist—I’ve reconstructed the Gist commit history in a new repository and shipped it to PyPI. # 22nd June 2019, 4:51 am
World Government Data. Launched last week, this is the Guardian’s meta-search engine for searching and browsing through data from four different government data sites (with more sites planned). Under the hood it’s Django, Solr, Haystack and the Scrapy crawling library. The application was built by Ben Firshman during an internship over Christmas. # 27th January 2010, 12:27 pm
WildlifeNearYou: It began on a fort...
Back in October 2008, myself and 11 others set out on the first /dev/fort expedition. The idea was simple: gather a dozen geeks, rent a fort, take food and laptops and see what we could build in a week.
[... 558 words]countdown_to_newyear.py. A quick Python / OS X script I knocked up last night to count in the new year (using the OS X “say” command). # 1st January 2010, 4:24 pm
Crowdsourced document analysis and MP expenses
As you may have heard, the UK government released a fresh batch of MP expenses documents a week ago on Thursday. I spent that week working with a small team at Guardian HQ to prepare for the release. Here’s what we built:
[... 2081 words]Django ponies: Proposals for Django 1.2
I’ve decided to step up my involvement in Django development in the run-up to Django 1.2, so I’m currently going through several years worth of accumulated pony requests figuring out which ones are worth advocating for. I’m also ensuring I have the code to back them up—my innocent AutoEscaping proposal a few years ago resulted in an enormous amount of work by Malcolm and I don’t think he’d appreciate a repeat performance.
[... 1674 words]Investigate your MP’s expenses. Launched today, this is the project that has been keeping me ultra-busy for the past week—we’re crowdsourcing the analysis of the 700,000+ scanned MP expenses documents released this morning. It’s the Guardian’s first live Django-powered application, and also the first time we’ve hosted something on EC2. # 18th June 2009, 11:16 pm
optfunc. Command line parsing libraries in Python such as optparse frustrate me because I can never remember how to use them without consulting the manual. optfunc is a new experimental interface to optparse which works by introspecting a function definition (including its arguments and their default values) and using that to construct a command line argument parser. Feedback and suggestions welcome! # 28th May 2009, 7:38 pm
geocoders. A fifteen minute project extracted from something else I’m working on—an ultra simple Python API for geocoding a single string against Google, Yahoo! Placemaker, GeoNames and (thanks to Jacob) Yahoo! Geo’s web services. # 27th May 2009, 10:02 am
djng—a Django powered microframework
djng is nearly two weeks old now, so it’s about time I wrote a bit about the project.
[... 1501 words]djangopeople.net on GitHub. I’ve released the source code for Django People, the geographical community site developed last year by myself and Natalie Downe (it hasn’t otherwise been touched since April last year, so it needs porting to Django 1.1). If you want a new feature on the site, implement it and I’ll see about merging it in. # 4th May 2009, 6:12 pm
rev=canonical bookmarklet and designing shorter URLs
I’ve watched the proliferation of URL shortening services over the past year with a certain amount of dismay. I care about the health of the web and try to ensure that URLs I am responsible will last for as long as possible, and I think it’s very unlikely that all of these new services will still be around in twenty years time. Last month I suggested that the Internet Archive start mirroring redirect databases, and last week I was pleased to hear that Archiveteam, a different organisation, had already started crawling.
[... 920 words]Rate limiting with memcached
On Monday, several high profile “celebrity” Twitter accounts started spouting nonsense, the victims of stolen passwords. Wired has the full story—someone ran a dictionary attack against a Twitter staff member, discovered their password and used Twitter’s admin tools to reset the passwords on the accounts they wanted to steal.
[... 910 words]backup_to_s3.py. I wrote Yet Another S3 backup script today. It’s a thin wrapper about boto that doesn’t do anything particularly impressive, but it fits my brain. # 21st September 2008, 6:51 pm
django-html. A small project I’m working on to make Django behave better with regards to HTML v.s. XHTML. # 9th September 2008, 11:59 pm
Announcing dmigrations
The team at Global Radio (formerly GCap Media) is the largest group of Django developers I’ve personally worked with, consisting of 14 developers split into two scrum teams, all contributing to the same overall codebase.
