I've got an op-ed in several papers across the Inland Empire today electrifying Metrolink service between Los Angeles and San Bernardino. It would make everyone's life a lot better and we are dumb not to do it.

👋 Hi everyone, I’m enabling GitHub Sponsors for Metro If Metro has improved your developer experience or saved your team's build times, I’d appreciate the support! Full pitch and ROI napkin math here: www.zacsweers.dev/sponsoring-m...

Cool to see that Micronaut is starting to adopt JSpecify and NullAway! github.com/micronaut-pr...

The new (or at least new to me) feature on Spotify to make radio stations “non-personalized” is great. Much less of hearing the same songs again and again!

So (685)568-556855?

Haven't seen this result from missing null checks before 🤔

If you need to get up to speed with null safety in #Java with #JSpecify and @manu.sridharan.net's #NullAway, watch @seb.deleuze.fr's excellent presentation from @springio.net 2025. www.youtube.com/watch?v=5Lbx...

Calling all motivated students and researchers to be part of the PLDI'26 Artifact Evaluation Committee! The first round of self-nominations ends on Dec. 22: pldi26.sigplan.org/track/pldi-2...

🎉PLDI'26 is already off to an incredible start, with a record breaking 398 paper submissions this year!🎉Let the reviewing fun begin!

The Spring team has done an amazing job introducing nullability annotation and checking for Spring Boot 4, using NullAway and other great tools. Really excited about the potential for increased nullness checking across the Java ecosystem!

A few thoughts on AI and education, from someone who uses AI and also teaches many levels of student. 1. Most importantly, it's not possible to know what will happen because no one knows what skills AI will or will not replace in the next few years.

LA Metro used to publish monthly reports detailing progress on each transit construction project. They stopped publishing them in August 2024, saying they do not keep these records and the public interest is clearly served better by not disclosing them. libraryarchives.metro.net/DPGTL/Status...

If you are visiting the United States, having a negative view of Trump is enough to get you denied entry. If this was coming out of Russia or China, we would deplore such an authoritarian attack on freedom of expression.

they’re saying Red One is a hit on Prime, but what does that even mean? how are we defining “hit” here? people didn’t actually want to pay for it, so what value does clicking play on a stream included with your free deliveries subscription have? @tavlin.bsky.social covered all this, of course
