Why we at $FAMOUS_COMPANY Switched to $HYPED_TECHNOLOGY (via) Beautiful piece of writing by Saagar Jha. “Ultimately, however, our decision to switch was driven by our difficulty in hiring new talent for $UNREMARKABLE_LANGUAGE, despite it being taught in dozens of universities across the United States. Our blog posts on $PRACTICAL_OPEN_SOURCE_FRAMEWORK seemed to get fewer upvotes when posted on Reddit as well, cementing our conviction that our technology stack was now legacy code.”

Deno 1.0. Deno is a new take on server-side JavaScript from a team lead by Ryan Dahl, who originally created Node.js. It’s built using Rust and crammed with fascinating ideas—like the ability to import code directly from a URL.

Weeknotes: Working on my screenplay
I’m taking an Introduction to Screenwriting course with Adam Tobin at Stanford, and my partial screenplay is due this week. I’m pulling together some scenes that tell the story of the Russian 1917 February Revolution and the fall of the Tsar through the lens of the craftsmen working on the Tsar’s last Fabergé egg. So I’ve not been spending much time on anything else.
[... 226 words]Web apps are typically continuously delivered, not rolled back, and you don't have to support multiple versions of the software running in the wild.
This is not the class of software that I had in mind when I wrote the blog post 10 years ago. If your team is doing continuous delivery of software, I would suggest to adopt a much simpler workflow (like GitHub flow) instead of trying to shoehorn git-flow into your team.

Using SQL to find my best photo of a pelican according to Apple Photos
According to the Apple Photos internal SQLite database, this is the most aesthetically pleasing photograph I have ever taken of a pelican:

Food consumption really only grows at the rate of population growth, so if you want to grow faster than that, you have to take market share from someone else. Ideally, you take it from someone weaker, who has less information. In this industry, the delivery platforms have found unsuspecting victims in restaurants and drivers.
Using SQL to Look Through All of Your iMessage Text Messages (via) Dan Kelch shows how to access the iMessage SQLite database at ~/Library/Messages/chat.db—it’s protected under macOS Catalina so you have to enable Full Disk Access in the privacy settings first. I usually use the macOS terminal app but I installed iTerm for this because I’d rather enable full disk access to a separate terminal program than let anything I’m running in my regular terminal take advantage of it. It worked! Now I can run “datasette ~/Library/Messages/chat.db” to browse my messages.

Waiting in asyncio. Handy cheatsheet explaining the differences between asyncio.gather(), asyncio.wait_for(), asyncio.as_completed() and asyncio.wait() by Hynek Schlawack.
Serving photos locally with datasette-media. datasette-media is a new Datasette plugin which can serve static files from disk in response to a configured SQL query that maps incoming URL parameters to a path to a file. I built it so I could run dogsheep-photos locally on my laptop and serve up thumbnails of images that match particular queries. I’ve added documentation to the dogsheep-photos README explaining how to use datasette-media, datasette-json-html and datasette-template-sql to create custom interfaces onto Apple Photos data on your machine.
AWS services explained in one line each (via) Impressive effort to summarize all 163(!) AWS services—this helped clarify a whole bunch that I haven’t figured yet. Only a few defeated the author, with a single question mark for the description. I enjoyed Amazon Braket: “Some quantum thing. It’s in preview so I have no idea what it is.”

Why we use homework to recruit engineers. Ad Hoc run a remote-first team, and use detailed homework assignments as part of their interview process in place of in-person technical interview. The homework assignments are really interesting to browse through—“Containerize” for example involves building a Docker container to run a Python app with nginx a and a modern cipher suite. I’m nervous about the extra burden this places on candidates, but Ad Hoc address that: “We recognize that we’re asking folks to invest time into our process, but we feel like our homework compares favorably to extensive on-site interviews or other evaluation techniques, especially for candidates who have responsibilities outside of their work life.”

Any time you can think of something that is possible this year and wasn’t possible last year, you should pay attention. You may have the seed of a great startup idea. This is especially true if next year will be too late.
Advice on specifying more granular permissions with Google Cloud IAM (via) My single biggest frustration working with both Google Cloud and AWS is permissions: more specifically, figuring out what the smallest set of permissions are that I need to assign in order to achieve different goals. Katie McLaughlin’s new series aims to address exactly that problem. I learned a ton from this that I’ve previously missed, and there’s plenty of actionable advice on tooling that can be used to help figure this stuff out.

Weeknotes: Datasette 0.43
My main achievement this week was shipping Datasette 0.43, with a collection of smaller improvements and one big one: a redesign of the register_output_renderer plugin hook.
Deno is a Browser for Code (via) One of the most interesting ideas in Deno is that code imports are loaded directly from URLs—which can themselves depend on other URL-based packages. On first encounter it feels wrong—obviously insecure. Deno contributor Kitson Kelly provides a deeper exploration of the idea, and explains how the combination of caching and lock files makes it no less secure than code installed from npm or PyPI.
Practical Python Programming (via) David Beazley has been developing and presenting this three day Python course (aimed at people with some prior programming experience) for over thirteen years, and he’s just released the course materials under a Creative Commons license for the first time.
