@bbatsov It's the Windows XP of Javas.

Every Java dies. Except 8. Java 8 is forever! Like Batman and Emacs!

XTDB Bi-Temporal SQL. Time-travel scrubbing. IYKYK. The "as-is vs as-was" convo is dead.

We still need a good syntax for collection literals, but Java is finally 'getting there' manning.com/books/data-ori…

I guess the frontier still exists, and is still moving west.

Sometimes I wonder, if we removed all Java's accumulated conventions and 'best practice', would people actually love the language? Most of the verbosity is self-inflicted.

In our latest podcast episode, host @malcolmsparks, with @joelittlejohn & @refset take a deep-dive into the ins and outs of building reliable software systems with guest speaker @markburgess_osl, the physicist behind Promise Theory. Tune in for insights 🔗 juxt.pro/blog/promise-t…

@AndrasGerlits If it's pull-only, have you considered SSE?

Earlier this week, @malcolmsparks @joelittlejohn and @jonpither visited challenger bank Kroo to learn about their use of Clojure. Huge thanks to Dean Chapman and @andfadeev for being such great hosts, and roaming the park with us for our chat!🙏

"What is @xtdb_com?" well, here's my latest <100s edit...let me know what you think! 🙏

How many different ways have you approached URI templating in your libraries/frameworks/apps? Did you know about IETF RFC 6570?juxt.pro/blog/uri-templ…

I appreciate what ONCE is trying to do to challenge SaaS pricing. As a compromise though, could we just please bring back some fairer per-usage billing plans? Per-seat billing has stopped me using so many tools that I'd be happy to pay for.

Well, that just made my day. Thank you Paulus!

The software industry seems to be more susceptible than most to producing waste. We spend too much time looking to fix this by optimising our ways of working, and not enough time validating if the path we're on is actually the right one. juxt.pro/blog/waste/

Where are the biggest sources of waste in software? Maybe not where you think. @joelittlejohn discusses ways to root out the biggest wastes that affect software teams. Read the full blog: juxt.pro/blog/waste/

I had an enjoyable conversation with Bediako George, CEO of Georgetown Software House, building headless spreadsheet engines in the cloud using #Clojure! Come read this brand new "Clojure In" juxt.pro/blog/clojure-i…

If you've ever wondered how systems like AWS Redshift are able to query data efficiently at such unbelievable scale, join @refset tomorrow at 4pm. He's talking columnar storage & processing. Signup here: us06web.zoom.us/webinar/regist…

Enjoyed chatting with @malcolmsparks, @refset, and @jarohen on this podcast about Rama, its Clojure roots, and some of the difficult engineering challenges we solved while developing it juxt.pro/blog/juxtcast-…

This has been some time in the works, but well worth the wait. We had a really nice long chat with Nathan, getting under the hood of Rama. Don't miss this!
