Did #AI write better Java? The experiment's back—#1BRC tests #IDE battles & hallucination. #Zencoder #JetBrains shine, but the flaws are surprising. All about context, integration #parsing.

Somebody did a pretty decent run at 1-billion-row-challenge with node. The author got it down to ~11 seconds (on their machine). Considering how fancy-pants rust etc people are doing it in perhaps 3-4 seconds, I'd say pretty decent.
Dive into the latest InfoQ #Java #TrendsReport with Ixchel Ruiz & Gunnar Morling!
🔍 Topics covered:
➡️ Benefits of Java's six-month release cadence
➡️ Project Lilliput & compact object headers

1 billion lines of code? No problem for AI, right? An AI didn't want to program! Steve Poole convinced it. Read his surprising results: https://javapro.io/2024/11/07/1-billion-record-challenge-ai-style/

The #OneBillionRowChallenge (#1BRC) went viral in the Java community earlier this year.
In this #InfoQ talk, Gunnar Morling dives into some of the tricks employed by the fastest solutions for processing the challenge’s 13 GB input file within less than two seconds.
Expect insights into:
• Parallelization and efficient memory access
• Optimized parsing routines with SIMD/SWAR
• Custom map implementations
He also shares personal stories and key takeaways from leading this challenge for and with the community.

TIL about the #1brc ...
Hope to see you tomorrow!
For all #1brc fans, we will lay the basic foundation for that exercise, without elaborating on tuning, by seeing the magic of the JVM and hardware... because it will hit us when benchmarking too naively.
@Devoxx #jmh #1brc
Created a repo with the step-by-step progress of the fastest #1brc solution. Key takeaways:
- @graalvm JIT provides 8+% for free. 🚀
- Parallellize and optimize data structures to get 95% of the way.
- Squeeze out the max by understanding the CPU.
My latest blog: “Java, Kotlin, and Pandas Data Frames Walk into the One Billion Row Challenge”. It compares 4 data frame solutions of #1BRC looking at the execution time, memory usage, and how readable the code is: https://link.medium.com/Wml1xdH1pMb
If you want to learn more about how Java Data Frames help with data-oriented programming when traditional data structures just won't cut it, come to my and @TheDonRaab talk “Are You Missing a Data Frame? The Power of Data Frames in Java” at @dev2next
Wer meinen Vortrag zu den ersten 80% der #1brc in Stuttgart verpasst hat, hat auf der #JavaForumNord die Chance, es nachzuholen. Ich freue mich auf Fragen und Diskussionen.
"Die 1 Milliarde Zeilen Herausforderung - #1BRC - Die ersten 80%"
Story of 1 Billion rows of data, where it is started from and how it is ended, incredible, in short, this video is saying never stop optimizing in #java or any language, we should improve ourselves and the code should work faster and faster. Thanks to @royvanrijn to collect all story in this video and keeping up with #1brc, Also respect to @graalvm feels like future of Java is bright. To be honest, I will rewatch/study this video more 🤓 hard to comprehend at first watch.
Nicht vergessen, 11:10 CEST im Schiller-Saal gibt es "Die ersten 80% des 1 Milliarde Zeilen Wettbewerbs #1brc" zu sehen. Freue mich auf rege Teilnahme und jede Menge Fragen. Ich werde nach Schätzungen fragen, damit es nicht langweilig wird. Jeder wird aus den ersten 80% etwas mitnehmen können, versprochen.

Waiting for my train to Java Forum Stuttgart. Join me for my talk about the first 80% of the #1BRC.
https://www.java-forum-stuttgart.de/vortraege/die-1-milliarde-zeilen-herausforderung-1brc/
In our latest blog post, Andy Stone tackles the #1BRC in Chapel, but with a twist. Rather than chasing speed through heroic programming, he uses Chapel’s features to leverage multicore parallelism while striving for readability. He even times the I/O!?
German followers, for your schedule, in case you can make it and attend one of my upcoming talks.
18 July 2024, JUG Darmstadt, "Microbenchmarks - Wer misst, misst Mist."

Hope to meet you soon in real life.
As usual, the slides for instant consumption: "#1BRC - THE FIRST 80% How to Read One Billion Rows Fast Enough". Thanks to the audience and thanks to all who came up and asked questions.

Nice video for pure Java perf-hacks 💪🏼 Remember that 1-billion row challenge a few months ago. https://youtube.com/watch?v=9-S_nZ5gzGE
Learning points: my bit-ops need refreshing 😅
