A benchmark for one-shot catastrophe avoidance in RL agents (MiniGrid LavaCrossing)
https://www.reddit.com/r/programming/comments/1ptjeoq/a_benchmark_for_oneshot_catastrophe_avoidance_in/

<!-- SC_OFF -->I’m sharing a new benchmark and paper that tests a specific capability in reinforcement learning agents: whether an agent can learn a permanent safety constraint from a single catastrophic failure and generalize it to unseen environments. The benchmark uses the official MiniGrid LavaCrossing environments (no custom modifications, fixed seeds). The protocol is: Run an agent until it experiences its first lava death Freeze the agent (no training, no gradients, no parameter updates) Evaluate on hundreds of unseen episodes Measure whether the agent ever steps into lava again The key metric is post_death_lava_deaths, which should be zero for true one-shot constraint learning. A public benchmark harness is included so others can test their own agents under the same rules. The paper describes the protocol, metrics, and design decisions in detail. Feedback from people working in RL, safety, or benchmarks would be especially welcome. <!-- SC_ON --> submitted by /u/anima-core (https://www.reddit.com/user/anima-core)

Implementing “Remember Me” in Java Swing (Real User Management Module)
https://www.reddit.com/r/programming/comments/1ptkrgl/implementing_remember_me_in_java_swing_real_user/

<!-- SC_OFF -->I’m working on a complete Library Management System using Java Swing and MySQL, and in Part 31 of the series I implemented a “Remember Me” functionality inside the User Management / Login module. Many Java Swing tutorials stop at basic login forms, but this video focuses on real-world behavior that users actually expect. What’s covered in this video? Login system with Remember Me checkbox Secure credential handling (no plain text passwords) Saving & loading login state properly Java Swing UI + backend logic separation JDBC + MySQL integration Best practices for desktop authentication Why this matters “Remember Me” seems simple, but implementing it correctly and safely in a desktop application is often skipped or done incorrectly. This video walks through the logic step-by-step as part of a real project, not a demo app. Who this is for? Java Swing learners Students building final-year projects Developers learning desktop authentication flows Anyone moving from basics to real systems YouTube Video (Part 31 – Remember Me Functionality):

Talks Worth Watching – Week of 2025-12-22
https://www.reddit.com/r/programming/comments/1ptm55f/talks_worth_watching_week_of_20251222/

<!-- SC_OFF -->This week's HFT Weekly roundup covers seven conference talks united by a common theme: domain knowledge beats generic optimization. Highlights include Greg Law's L3 logging library achieving 1ns latency by eliminating locks via memory-mapped buffers and atomic operations, Khalil Estell's 90% reduction in C++ exception overhead through smarter table search algorithms, Denis Yaroshevskiy explaining C++26 hazard pointers for lock-free config access at Meta, and Andrew Drakeford demonstrating a million-times speedup in leave-one-out regression by exploiting mathematical properties rather than just cache locality. The week's takeaway: before reaching for SIMD or optimizing data layout, spend time understanding what your code actually does at the domain level—that's where the biggest wins hide. <!-- SC_ON --> submitted by /u/OkSadMathematician (https://www.reddit.com/user/OkSadMathematician)

PyTorch vs TensorFlow in Enterprise Isn’t a Model Choice; It’s an Org Design Choice
https://www.reddit.com/r/programming/comments/1pttx2e/pytorch_vs_tensorflow_in_enterprise_isnt_a_model/

<!-- SC_OFF -->Most PyTorch vs TensorFlow debates stop at syntax or research popularity, but in enterprise environments the real differences show up later; deployment workflows, model governance, monitoring, and how easily teams can move from experiment to production. PyTorch often wins developer mindshare, while TensorFlow still shows up strong where long-term stability, tooling, and standardized pipelines matter. The “better” choice usually depends less on the model and more on how your org ships, scales, and maintains ML systems.

We reduced transformer inference calls by ~75% without changing model weights (MFEE control-plane approach)
https://www.reddit.com/r/programming/comments/1puks9j/we_reduced_transformer_inference_calls_by_75/

<!-- SC_OFF -->I’ve been working on a systems paper proposing a simple idea: instead of optimizing how transformers run, decide whether they need to run at all. We introduce Meaning-First Execution (MFEE), a control-plane layer that gates transformer inference and routes requests into: - RENDER (run the model) - DIRECT (serve from cache / deterministic logic) - NO_OP (do nothing) - ABSTAIN (refuse safely) On a representative replay workload (1,000 mixed prompts), this reduced transformer execution by 75.1% while preserving 100% output equivalence when the model was invoked. Below is a derived economic impact table showing what that reduction implies at scale. These are not claims about any specific company, just linear extrapolations from the measured reduction. Economic Impact (Derived) Example Workload Savings (Based on Original Paper Results) Workload Type Daily Requests Transformer Reduction Annual GPU Cost Savings Web Search-like 8.5B 75% $2.1B – $4.2B Code Assist 100M 80% $292M – $584M Chat-style LLM 1.5B 70% $511M – $1.0B Enterprise API 10M 75% $27M – $55M Assumptions: - GPU cost: $1.50–$3.00/hr - Standard transformer inference costs - Linear scaling with avoided calls - Based on 75.1% measured reduction from the paper If you think these numbers are wrong, the evaluation harness is public. What surprising to me is that a lot of effort in the ecosystem goes toward squeezing marginal gains out of model execution, while the much larger question of when execution is even necessary seems to be the more important examination. MFEE isn’t meant to replace those optimizations. It sits upstream of them and reduces how often they’re even needed in the first place.

GitHub repos aren’t documents — stop treating them like one
https://www.reddit.com/r/programming/comments/1pun9oq/github_repos_arent_documents_stop_treating_them/

<!-- SC_OFF -->Most repo-analysis tools still follow the same pattern:
embed every file, store vectors, and rely on retrieval later. That model makes sense for docs.
It breaks down for real codebases. Where structure, dependencies, and call flow matter more than isolated text similarity. What I found interesting in an OpenCV write-up is a different way to think about the problem:
don’t index the repo first, navigate it. The system starts with the repository structure, then uses an LLM to decide which files are worth opening for a given question. Code is parsed incrementally, only when needed, and the results are kept in state so follow-up questions build on earlier context instead of starting over. It’s closer to how experienced engineers explore unfamiliar code:
look at the layout, open a few likely files, follow the calls, ignore the rest. In that setup, embeddings aren’t the foundation anymore, they’re just an optimization. <!-- SC_ON --> submitted by /u/Different-Opinion973 (https://www.reddit.com/user/Different-Opinion973)
