You know Google Maps? What I do is, like, build little pieces of Google Maps over and over for people who need them but can’t just use Google Maps because they’re not allowed to for some reason, or another.
Replicating SQLite with rqlite (via) I’ve been trying out rqlite, a “lightweight, distributed relational database, which uses SQLite as its storage engine”. It’s written in Go and uses the Raft consensus algorithm to allow a cluster of nodes to elect a leader and replicate SQLite statements between them. By default it uses in-memory SQLite databases with an on-disk Raft replication log—here are my notes on running it in “on disk” mode as a way to run multiple Datasette processes against replicated SQLite database files. # 28th December 2020, 7:51 pm
While copywriting is used to persuade a user to take a certain action, technical writing exists to support the user and remove barriers to getting something done. Good technical writing is hard because writers must get straight to the point without losing or confusing readers.
I’ve been working on some fundamental changes to Datasette’s internal workings—they’re not quite ready for a release yet, but they’re shaping up in an interesting direction.[... 760 words]

At GitHub, we want to protect developer privacy, and we find cookie banners quite irritating, so we decided to look for a solution. After a brief search, we found one: just don’t use any non-essential cookies. Pretty simple, really. 🤔 So, we have removed all non-essential cookies from GitHub, and visiting our website does not send any information to third-party analytics services.
I get asked a lot about learning to code. Sure, if you can. It’s fun. But the real action, the crux of things, is there in the database. Grab a tiny, free database like SQLite. Import a few million rows of data. Make them searchable. It’s one of the most soothing activities known to humankind, taking big piles of messy data and massaging them into the rigid structure required of a relational database. It’s true power.
Something to pay attention to when making a build v.s. buy decision is the impact that billing models will have on your usage of a tool.[... 410 words]
This week I launched datasette.io—the new official project website for Datasette.[... 1956 words]
If you are pre-product market fit it’s probably too early to think about event based analytics. If you have a small number of users and are able to talk with all of them, you will get much more meaningful data getting to know them than if you were to set up product analytics. You probably don’t have enough users to get meaningful data from product analytics anyways.
datasette.io (via) Datasette finally has an official project website, three years after the first release of the software. I built it using Datasette, with custom templates to define the various pages. The site includes news, latest releases, example sites and a new searchable plugin directory. # 11th December 2020, 4:11 am
The case against client certificates (via) Colm MacCárthaigh provides a passionately argued Twitter thread about client certificates and why they should be avoided. I tried using them as an extra layer of protection fir my personal Dogsheep server and ended up abandoning them—certificate management across my devices was too fiddly. # 9th December 2020, 2:41 pm
This week: Improvements to
datasette-graphql, plus Datasette 0.52 and a flurry of dot-releases.
The secrets of Monkey Island’s source code (via) To celebrate the thirty year anniversary of the Secret of Monkey Island the Video Game History Foundation interviewed developer Rod Gilbert and produced this comprehensive collection of cut content and material showing how the game was originally constructed. # 5th December 2020, 4:32 pm
Discoverable CLIs have comprehensive help texts, provide lots of examples, suggest what command to run next, suggest what to do when there is an error. There are lots of ideas that can be stolen from GUIs to make CLIs easier to learn and use, even for power users.
Command Line Interface Guidelines (via) Aanand Prasad, Ben Firshman, Carl Tashian and Eva Parish provide the missing manual for designing CLI tools in 2020. Deeply researched and clearly presented—I picked up a bunch of useful tips and ideas from reading this, and I’m looking forward to applying them to my own CLI projects. # 4th December 2020, 8:44 pm
The value of a product is the number of problems it can solve divided by the amount of complexity the user needs to keep in their head to use it. Consider an iPhone vs a standard TV remove: an iPhone touchscreen can be used for countless different functions, but there’s very little to remember about how it works (tap, drag, swipe, pinch). With a TV remove you have to remember what every button does; the more things you can use the remote for, the more buttons it has. We want to create iPhones, not TV remotes.
Scaling Datastores at Slack with Vitess (via) Slack spent three years migrating 99% of their MySQL query load to run against Vitess, the open source MySQL sharding system originally built by YouTube. “Today, we serve 2.3 million QPS at peak. 2M of those queries are reads and 300K are writes. Our median query latency is 2 ms, and our p99 query latency is 11 ms.” # 1st December 2020, 9:30 pm
New for AWS Lambda – Container Image Support. “You can now package and deploy Lambda functions as container images of up to 10 GB in size”—can’t wait to try this out with Datasette. # 1st December 2020, 5:34 pm
Scaling React Server-Side Rendering (via) Outstanding, detailed essay from 2017 on challenges and solutions for scaling React server-side rendering at Kijiji, Canada’s largest classified site (owned by eBay). There’s a lot of great stuff in here, including a detailed discussion of different approaches to load balancing, load shedding, component caching, client-side rendering fallbacks and more. # 30th December 2019, 10:26 pm
Guide To Using Reverse Image Search For Investigations (via) Detailed guide from Bellingcat’s Aric Toler on using reverse image search for investigative reporting. Surprisingly Google Image Search isn’t the state of the art: Russian search engine Yandex offers a much more powerful solution, mainly because it’s the largest public-facing image search engine to integrate scary levels of face recognition. # 30th December 2019, 10:23 pm
Machine Learning on Mobile and at the Edge: 2019 industry year-in-review (via) This is a fantastic detailed overview of advances made in the field of machine learning on the edge (primarily on mobile devices) over 2019. I’m really excited about this trend: I love the improved privacy implications of running models on my phone without uploading data to a server, and it’s great to see techniques like Federated Learning (from Google Labs) which enable devices to privately train models in a distributed way without having to upload their training data. # 30th December 2019, 10:17 pm

For creative work, you can’t cheat. My believe is that there are 5 creative hours in everyone’s day. All I ask of people at Shopify is that 4 of those are channeled into the company.
free-for.dev (via) It’s pretty amazing how much you can build on free tiers these days—perfect for experimenting with side-projects. free-for.dev collects free SaaS tools for developers via pull request, and has had contributions from over 500 people. # 26th December 2019, 10:03 am
