Happy Belated Birthday Squeak! news.squeak.org/2025/10/01/h...

Somehow missed this gem from #Devoxx with @smarks.bsky.social discussing checked exceptions with @nipafx.dev www.youtube.com/watch?v=lnfn...

I'm seeing lots of AI generated Java Dukes appearing with a mouth, feet, ears and more. Tip: when using AI, upload this “Duke Specification” image, prompt AI to follow as a reference. I think you'll find the resulting image is much better. Ex: "draw duke on a skateboard referencing this spec image"

Why MCP Fun at Devoxx with Lize, Dimitris, @glaforge.dev and @jdubois.bsky.social @devoxx.com @langchain4j.dev

At @devoxx.com listening to talks on Pattern Matching, Serialization and Ask the Architects. There is a lot of research bubbling away under the surface by the excellent #Java team.

"I need an array of a generic type. Why won't the compiler let me create one?" "How do I find the intersection of two Sets?" These and all other questions about generics and collections are answered in the newly published 2nd edition of Java Generics and Collections. 1/2 #Devoxx #Java

"Why haven't they fixed this yet?" @smarks.bsky.social and Maurice talking about ConcurrentException etc in #java at #devoxx Great talk, but when they cover Vector and Hashtable, I can't stop and think: "Why haven't they deprecated this yet?"

It took me rather too long to realize that George Conway is not talking about computer network cables.

With Tom Lehrer's passing, I suppose this is a moment to share the story of the prank he played on the National Security Agency, and how it went undiscovered for nearly 60 years.

I bought & started reading "Java Generics and Collections 2nd Edition" by @mauricenaftalin.bsky.social, Philip Wadler, with @smarks.bsky.social. I'm really enjoying it so far! It's like finding 18 missing & useful chapters about Java Generics & Collections that I didn't have to write in my book! ❤️🙏

#EclipseCollections 12.0 will be released this week. The release has a lot of great contributions from the open source community. The 11.1 release is excellent and stable, and compatible w/ Java 8. EC 12.0 requires Java 11 or higher. Stay tuned! donraab.medium.com/there-is-no-...

BREAKING: The White House lashed out at the creators of this ad for "fear-mongering". It must have really struck a nerve. Maybe they don't like being outed as fascists. You know what to do: SPREAD THIS EVERYWHERE! #MAGAKidnappers

#Java peers, I ask you to please follow @thedonraab.bsky.social. His expertise and experiences are worth learning more about.

The Minnesota assassin appears to be a hate-filled right winger. So can we stop walking on eggshells about MAGA's legitimization of political violence? Yes, Republicans have also been the target of inexcusable violence, but this isn't a "both sides" issue. 1/ A🧵on the danger.

As we say on the internet, "some personal news." After 39 years on the job I am retiring as an NYU professor. In this thread I will take a few moments to reflect on my academic career. Spoiler alert: I am not leaving the field, or the fight for a public service press. 1/

Newsom may be a son of a bitch, but he's our son of a bitch.

Weird they're showing Swan Lake on Fox right now

Lemme explain what bilateral trade deficits are, so that you can better understand -- and perhaps be infuriated by -- the intellectual error that's transforming our economy. #TeachEcon

OTD…May 23, 1995 Happy Birthday, #Java! Here’s to 30+ more years with a beautiful combination of technology innovation and community participation!

I've enjoyed most of that 30 years working on Java, first on the early http server side, then downsizing Java for Mobile devices, and now as a developer of the core libraries. Keep it coming!

The documentation for these commands is actually online! See p. 201 of this document: www.bitsavers.org/pdf/hp/2000T... (Yay BitSavers!)

Watching through Andor season two and imagining a future companion book "The Andor Guide to Business" with chapters like: "Effective Meetings" by Major Lio Partagaz, ISB "Get the people you need when you need them" by Luthen Rael

Sanity-checking where we are with Leyden(-adjacent) improvements for small HelloWorld-style apps. We have breached through my own psychological 20ms barrier now!

We integrated #java 's new Stable Values feature just now! This will allow developers and library developers to benefit from the "secret" @Stable annotation that the internal JDK code has been using for years. This can bring significant performance improvements to your code! openjdk.org/jeps/502

There's this urban legend that when Dijkstra wrote "Go To Considered Harmful", he was thinking of the FORTRAN-style "wild goto" that could jump between functions or into the body of the loop. I only learned it's a myth after making that claim and getting corrected by Mat Klad and @without.boats 1/🧵

Whether you take this version of the other, I encourage you to read the content. Great reflection on complex API design!

In ~24 hours, the hardback 📙 drops. Watch for blog update! Bigger pages. Bigger fonts. Bigger pictures. Full color, w/ premium paper. "Eclipse Collections Categorically: Level up your programming game", the hardback version, stands on its own. Thank you for waiting! Enjoy! 🙏

I am quite certain that Trump was not talking about the Olmec-head-on-Tesla test. (This was an art installation by Chavis Mármol.) mexiconewsdaily.com/culture/got-...

Movie you’ve watched more than six times using gifs. (“Hard mode” no Star Wars, trek, or LOTR)

Costco is a really popular subject for business-success case studies but I feel like business guys kinda lose interest when the upshot of the study is like "just operate with scrupulous integrity in all facets and levels of your business for four decades" and not some easy-to-fix gimmick

The great @hcrichardson.bsky.social from her speech on the 250th anniversary of the lighting of the lanterns in Boston’s Old North Church. Read this excerpt to the end and you will be rewarded. Read it aloud and it gets better. heathercoxrichardson.substack.com/p/april-18-2...

1. The DOJ has sent threatening letters to several medical journals, focused around whether these journals are spreading misinformation that harms the American people and suppressing alternative viewpoints. I study how the norms and institutions of science facilitate discovery and self-correction.

Again, for those of you who have Republican representatives and senators, this is the time to call them and demand they take action. They're feeling the heat already, but throw some gas on the fire for them.

Here’s some #Maven dependency advice: if your source code imports a class then make sure its provider (the JAR file) is explicitly listed as a dependency. DO NOT, I repeat, DO NOT rely on the transitive closure of resolved dependencies. If used, declare it. You’ll thank me later.

JDK 24 Security Enhancements: seanjmullan.org/blog/2025/04... Highlights of this release include 2 new core quantum-resistant cryptographic algorithms (ML-KEM and ML-DSA), a preview API for Key Derivation Functions, and the permanent disabling of the Security Manager. #jdk #java #security #crypto

I've got a bunch of DMs here asking me, a retired military officer, what I think about Trump going golfing instead of meeting the returning caskets of four US soldiers killed overseas. It might be an unpopular opinion, but you know, good, go the fuck golfing. 1/

Four young soldiers were recovered after days of searching underwater & in the mud for them. This is why they were there…my homage in @BulwarkOnline to the “wrenches” and our allies. Be thou at peace www.thebulwark.com/p/why-we-tra...

My presentation on #Java Stream Gatherers at #JavaOne is now available: youtu.be/v_5SKpfkI2U?...

I had been reluctant to amplify the theory that Trump's "reciprocal tariff rate" for a given country was based on the dumb calculation: (bilateral trade deficit) divided by (imports from that country) But now USTR has confirmed it. Brief 🧵

Happy Trans Day of Visibility to all you wonderful lovely people! 🏳️‍⚧️ Thank you for sharing as much of yourselves as you are comfortable sharing; all our lives are richer for it ❤️

Cory Booker has taken the Senate floor and plans to filibuster as long as he’s physically able to protest the complete disregard for the rule of law by Trump and Musk. Watch here: www.c-span.org/event/us-sen...

Remembering Carl. You are sorely missed. RIP 🖤

Improve a first line by substituting Mrs. Dalloway. A Saturday afternoon in November was approaching the time of twilight, and the vast tract of unenclosed wild known as Mrs. Dalloway embrowned herself moment by moment.

The DOGEboys’ hyper-confidence in ability to quickly reimplement huge mission-critical software is reminiscent of young Pham from Vernor Vinge’s Deepness in the Sky(1999) set 5000 years from now, which I couldn’t resist quoting: queue.acm.org/detail.cfm?i...
