Preview of some rewrites coming to Quokka, courtesy of my coworker @katafrakt.eurosky.social at Jump... Our DX team has leaned pretty heavily into trying to automate performance improvements like these. If the formatter can do it for you, why not? 😄 #ElixirLang

OMG, latest version of Hex (`mix local.hex --force`) prints out CVEs that affect your packages any time you run `mix deps.get` 🤩 #ElixirLang

mix deps.get output, showing Earmark 1.4.48 marked as "RETIRED!" and "VULNERABLE!" due to CVE-2026-48591, "Stored XSS via unescaped HTML attribute values in earmark"

Happy Monday from GitHub. 😌 Hope you weren't planning to get any work done today. 🙃

One Weird Trick to avoid getting pwned by these zero-days that depend on you grabbing a freshly compromised OSS package: (Note: requires you to use a lockfile everywhere. You're using a lockfile everywhere, right?)

Boy, thank goodness we have LLM generated tests for this code, otherwise we'd have no tests at all!

LLM-generated "test" code which doesn't call into actual production code at all, instead making assertions about the test setup itself.

Haha, I’m mostly kidding. I do have a good amount of forest nearby. No mountains for hundreds of miles, unfortunately. I dug a koi pond last year, though!

@posthog.com The new web site feels like an April Fools joke... as part of a team paying $$$$/month, I can't figure out how to get into the dashboard to actually use the app. 😬

Tip for Mac users: the built-in keyboard replacements tool is great. You can use it to get text-to-emoji replacement on essentially any text field (unless the developer has done something truly foul—looking at you, Gmail compose field). E.g., I type :hoot to get the owl emoji.

Really enjoyed @nicholasjhenry.github.io’s talk on validating business rules in Ecto. It had never occurred to me that we should validate some of our association rules in the context, not the schema’s changeset function, but I’m convinced!

The nicest thing that has ever been said about me as a dev 🥹 P.S. If your company doesn’t have a shoutouts channel in Slack, you should get on that. 😄

A Slack message that reads:
Shoutout to Tyler Young for writing code in a way that makes it super clear for new devs to understand and follow what is happening. Clarity is easily overlooked, especially when building fast, but his code is always really clear.

Two interesting things to note: - The overwhelming majority of poll respondents on both Twitter and Mastodon say they'd read it, but the overwhelming majority of replies on all 3 sites say they wouldn't - As I've always found, people on Mastodon have higher rates of self-reported conscientiousness

Poll results showing 81% of respondents saying they would read the long moduledoc, while 19% say they would speed past it

Brilliant? Stupid? I'm not really sure, but it works. Links in my React component embedded in LiveView no longer trigger a full page load. 👀 #ElixirLang

A React component with an anchor element. The attributes data-phx-link="redirect" and data-phx-link-state="push" have been added to the anchor, mirroring the attributes LiveView's link component applies.

Citing @david.bernheisel.com's Safe Ecto Migrations is like citing the Bible.

Slack message quoting a paragraph from Safe Ecto Migrations explaining that @disable_migration_lock requires you to run the migration on a single node only, since there is no protection against multiple nodes running the same migration at the same time.

Once a year I check on the value of the Generac stock I bought at a 10% discount during the 6 months I worked there (one of two individual stocks I've bought in my entire life). Once a year I remind myself I should not be picking stocks. The dot is where I bought.

v0.6.0 of parameterized_test is out now, adding attribution to the stacktrace of failing tests to show which set of parameters caused the failure. This massively improves the debuggability of these tests. Many thanks to @wojtekmach.bsky.social and @dorgan.ar for tips on the implementation!

Apple's had a lot of misses in the last few years, but this is by far the worst. Are they really so proud of their goofy reactions that they have to nag me *every*, *single* Zoom call about them? The fact that the close button doesn't work is just icing on the cake.
