There’s a lawsuit against WhatsApp making the rounds today, claiming that Meta has access to plaintext. I see nothing in there that’s compelling; the whole thing sounds like a fishing expedition.

Setting Chrome to mimic a 3G network it's even worse! 8 distinct layouts.

What the heck is going on with Spotify's embedded player that it flashes through no fewer than six different layouts as it loads?

Happy New Year 🎉 New year, new resolutions: fewer null checks, clearer error handling, and getting nullability right in GraphQL. Let's see how far we get this year.

I updated grats.capt.dev internal snapshot tests to serialize using markdown and the result is so nice! Snapshot output now has syntax highlighting and nice readable headings showing what each bit of the output means.

I think the npm client should probably follow pnpm in making post-install scripts be opt-in and recording that decision in package-lock, so if a package that was previously inert suddenly has a post-install script, it wouldn't execute. www.sonatype.com/blog/the-sec...

GraphQL error handling sucks. There, I said it. Null checks everywhere, and ambiguity: error, or true null? We've all been there. In this talk, Benjie Gillam shows how to fix GraphQL's biggest mistake in 512 bytes. 👇 youtu.be/odwQUAkmW44

There were only about 50 skins which were not already in our collection. Further confirmation that the museum's >101,000 skins represent the vast majority of all skins ever created.

Jordan Eldredge@capt.dev

I’ve been made aware of a 2013 “panic download” archive of downloads.nullsoft.com containing ~60k Winamp skins. Downloaded and hashing all the files to find any which are not already in the Winamp Skin Museum.

📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms). It’s also concerning. 1/

PSA: we're aware that Signal is down for some people. This appears to be related to a major AWS outage. Stand by.

Markdown+metadata is such a good format for blog posts. But deploy-to-publish feels heavyweight, and I often want to publish from my phone. Current setup: Author in Notion and pull from Notion API to Markdown in SQLite DB. Site renders from SQLite.

I also periodically materialize the Markdown in the DB to files in the repo so that I have a durable backup with course grained history in a fully open format. This is a hedge against wanting to drop Notion for something else (Obsidian?)
