Can #LLMs replace developers? Introducing RepoCod-Lite 🐟 for faster evaluation to answer this: 200 of the toughest #RepoCod #code-generation tasks: - GPT-4o and other LLMs have < 10% accuracy/pass@1 on RepoCod-Lite tasks - Leaderboard lt-asset.github.io/REPOCOD/ - 67 repository-level, 67 file-level, and 66 self-contains tasks - Detailed problem descriptions (967 tokens) and long canonical solutions (918 tokens) - Dataset: huggingface.co/datasets/lt-as… Thanks to the great feedback from #swe-bench’s @OfirPress, here are some clarifications about #RepoCod (lt-asset.github.io/REPOCOD/): Compared to #SWE-Bench, RepoCod tasks are - General code generation tasks,  while SWE-Bench tasks resolve pull requests from GitHub issues - With 2.6X more tests per task (313.5 compared to SWE-Bench’s 120.8) Compared to #HumanEval, #MBPP, #CoderEval, and #ClassEval, RepoCod has 980 instances from 11 Python projects, with - Whole function generation - Repository-level context - Validation with test cases, and  - Real-world complex tasks: longest average canonical solution length (331.6 tokens) and the highest average cyclomatic complexity (9.00) #LLMs #LLM4Code #security #codegen

We encourage undergraduate, master’s, and early-stage PhD students interested in programming languages to apply for PLMW at PLDI 2026. It is a great opportunity to learn from researchers, build connections, and explore future directions in PL.

🏅Grateful for our 2 Most Influential Paper (N-10) awards at #ICSE2026. 1️⃣ Most Influential Paper (#MIP) Award: Automatically Learning Semantic Features for Defect Prediction 2️⃣ Most Influential SEIP Paper (#MIPS) Award Retrospective: Online Defect Prediction for Imbalanced Data

Looking forward to giving the #MIP talk with Song during the #ICSE2026 Awards Session on April 15 (tinyurl.com/icse16mip). @ICSEconf Paper: tinyurl.com/ICSE16DBN Journal: tinyurl.com/TSEDBN I’m thankful these ideas continue to have lasting impact 10 years later. 🙏

These two papers almost bookend a story. The 1st was among the earliest to show how #DeepLearning could be used for software defect prediction. The 2nd focused on the deployment in practice: imbalanced data and future-data leakage. #SoftwareEngineering #ICSE2026

AWS Security Agent is now generally available. Scale security testing across your application portfolio with on-demand penetration testing that matches your development velocity. By conducting tailored attack scenarios, AWS Security Agent identifies validated vulnerabilities with reproducible proof and actionable fixes.

We measured the effects of more AI coding agents, with the same conclusion: Development velocity (commits, lines added) increases, but it is short lived, and it comes at the cost of code quality and technical debt (static analysis warnings and code complexity go up substantially)

@swarat Congratulations, Swarat! Very well deserved!

Honored to be named a 2025 #ACMFellow! Many thanks to my students, collaborators, and mentors over the years -- working with you has been a privilege. And a big thank-you to my family for their perennial love, support, and patience.

Sequoia partner @sonyatweetybird says we're going from the age of product-led growth to the age of agent-led growth. "You see this most clearly if you're using Claude Code actively. It says, 'Hey, for a database, you should use Supabase. For hosting, use Vercel.' It's choosing for you, the stuff you should be using." "Product-led growth brought us closer to the vision of 'best product wins,' but ultimately people are still lazy. They can't read all the reviews, and they kind of default to what looks cool on the website." "Whereas your agent has infinite time to go and make these choices for you. It can go and read all the documentation, read all the user comments, and figure out [what you need] for your use case."

🚀 Excited to share the preview launch of AWS Security Agent! A rewarding year working with amazing scientists and engineers to bring this from design to code to launch. Learn more 👇 tinyurl.com/AWSSecurityAge… #AWS #AI #Agents #Security #AWSSecurityAgent #reInvent
