Do you remember the #1BRC? When I asked AI back in 2024 for a solution, I got a normal stream suggestion or something similar as a plain Java loop. When I ask AI now, I get the winning solution or parts of it suggested. Even if I try to exclude these, it always wants to come back to some of these rather cutting-edge-hacky solutions.
So, no open source means no AI programming helpers or agents. More AI programmed content means no new ideas and no innovation. At least for now!
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.

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/

Steve Poole tested AI coding tools for bug-finding, Javadoc generation, and JUnit creation using a 1,000-line Java program. Most tools excelled in documentation but struggled with bugs and tests, except for JetBrains AI Assistant, which produced compilable code. Poole then tackled the "1 Billion Records Challenge" to retrieve and analyze massive temperature data files, iterating prompts to improve results. Codeium, Amazon Q Developer, and Microsoft CoPilot produced functional code, but many failed on large datasets. Poole found AIs useful for code review and snippets, but complex coding tasks require iterative prompting and human intervention, limiting AI's current capabilities.
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.
