‼️ An OkHttp interceptor to defend against today’s TLS disaster

‘the main purpose of unit tests is keeping your code from being violently shat on by others in an environment where everything changes uncontrollably all the time.’ (they also defend against blunders by future-me)

Didn't expect to be targeted by a bus stop ad!

Okay, here's my first (published) attempt to write about what it's been like on the other side of the layoffs at Cash App (and all of Block): www.billjings.net/posts/title/... The answer is that it's been weird! Alienated, but not alone.

KotlinPoet 2.4.0 has explicit backing fields, multi-field value classes and improved formatting! 🖨️ github.com/square/kotli...

Wherein I rant about OO data modeling and slap an upbeat title on it: www.billjings.net/posts/title/...

Android 17’s better HTTPS privacy is rad. I’m proud that OkHttp 5.5 makes it easy to adopt.

This one's exciting! blog.gradle.org/resilient-sync

Okio 3.18 has what you long for: unsigned reads and writes. 🗿

Guess what, my new health insurance app, not every Spanish resident has two last names! And yeah, read this: www.kalzumeus.com/2010/06/17/f...

Something big might happen to the Kotlin Multiplatform Ecosystem 👀 We were never too happy about how Kotlin publishes and resolves KMP libraries. It takes up significantly more space than it has to, produces a ton of artifacts and Maven modules, and is just... complex!

Something that I really enjoy about working at JetBrains is dogfooding everything all the time: IDEA, its plugins, the Kotlin Gradle Plugin, Kotlin itself. So cool to file bugs and see them picked up, triaged and fixed!

Metro 1.3.0 has rich diagnostics and experimental runtime tracing! github.com/ZacSweers/metro/re...

Metro 1.2.0 has Hilt interop, provider inlining, improved compiler performance, and leaner runtime primitives! github.com/ZacSweers/metro/re...

Okhttp 5.4 interceptors can do more. 🎸 square.github.io/okhttp/chang...

KotlinConf'26 started today in Munich, and there’s a lot to announce. Kotlin is easier than ever to get started with, and it now powers some of the most-used apps in the world – both on the backend and mobile. 🧵 Here are the highlights from the opening keynote.

I'll be giving a talk about Metro's internals tomorrow at @kotlinconf.com! This'll be an advanced talk that assumes familiarity with Metro, and is a sort of part 2 of my "Navigating Dependency Injection with Metro" talk last year. You can find it here: www.youtube.com/watch?v=jVfm...

Metro 1.1.0 and 1.0.1 are out now! This is largely a performance release. They are identical except 1.1.0 drops Kotlin 2.2.0 - Improved compiler performance - Lots of tracing improvements - SwitchingProvider now generates tableswitch bytecode - Kotlin 2.4.20 support github.com/ZacSweers/metro/re..

Prime Minister Pedro Sánchez and I are deepening our cooperation in energy, AI, and digital sovereignty — and we have a goal to double two-way trade between Canada and Spain. Thank you for the jersey, and see you at the World Cup! 🇨🇦 🇪🇸

A couple of months ago I was laid off by Block. I’ve mostly been doing dad stuff since then but I’m very gently looking to start having conversations and figure out what’s next for me. I’d love to chat with anyone that thinks I might be a good fit! gordonfontenot.com/hire-me

Barcelona is gorgeous this time of the year.

We're wrapping up our migration to Metro internally for Square Android. I summarized some of our challenges and steps we took in a blog post. If you use Dagger 2 for a Kotlin project, then you should migrate to Metro sooner rather than later. engineering.block.xyz/blog/metro-m...

I built a tiny IntelliJ IDEA plugin for something that had been bothering me for years github.com/saket/intell...

KotlinPoet 2.3.0 supports typealias declarations inside types, has new convenience API for adding annotations and ships with a healthy dose of bug fixes. Time for a version bump! 🤜🤛 github.com/square/kotli...

What happens to Square / Block Android OSS projects post layoffs? Let's start with some context OSS at Square is mostly a happy accident. Jack hired Bob, who's job was attracking world class engineers, and he did that through talks & OSS.

Dear Competition Bureau Canada...

It is the year 2026, people are still confused about compileSdk and targetSdk. (e.g. you can have targetSdk that is higher than compileSdk) www.liutikas.net/2026/02/13/R... Maybe this will explain it a bit more. #android

Today is Bandcamp Friday - Bandcamp is waiving their fees and passing the funds directly to the artists - so I went shopping. Got the entire Spiritbox discography and a few As I Lay Dying and Parkway Drive albums. One step closer to cancelling my Spotify subscription!

🚨 NEW EPISODE 🚨 Everyone’s watching Davos - so we’re talking about some of the other European news. This week: potatoes in Berlin 🥔, a leaked “Made in Europe” proposal, and an interview with a sitting UK cabinet minister on the UK’s “reset” with the EU. www.europeanspodcast.com/all-episodes...

As great powers abandon rules and values for their own interests, middle powers like Canada have a choice: compete with each other for favour or act together with impact.

Giving it a shot
