    DeepSeek-R1 had an RLHF step in their post-training pipeline (section 2.3.4 of their technical report[1]). In addition, the "reasoning-oriented reinforcement learning" step (sectio…

    Glad to see the author making a serious effort to fill the gap in public documentation of RLHF theory and practice. The current state of the art seems to be primarily documented in…

    I prefer the GDB Graphical Interface in Emacs[1] (M-x gdb), rather than the more basic integration via GUD[2] (M-x gud-gdb). I’ve had to switch to GUD to run lldb recently, and I m…

    GDB also has a built-in text user interface (TUI) that is surprisingly easy to use[1]. It even supports mouse interaction. [1] https://sourceware.org/gdb/current/onlinedocs/gdb.htm…

    Try disabling VC over Tramp connections[1]: (setq vc-ignore-dir-regexp (format "\\(%s\\)\\|\\(%s\\)" vc-ignore-dir-regexp tramp-file-name-regexp)) VC is quite chatty and assumes th…

    It depends if they are using a “vanilla” instruction-tuned model or are applying additional task-specific fine-tuning. Fine-tuning with data that doesn’t have misspellings can make…

    If you want to be cautious, I have somewhat higher confidence in the versions of Emacs packages published on the Debian repositories[1] than the ones on ELPA/MELPA. The downside is…

    Are there any open source self-hostable tracking/project management tools that still have a committed team and forward momentum? I used to self-host a Phabricator instance, which I…

    Boost.Heap has this functionality. Or if you want to stick with the standard library it’s fairly easy to use the *_heap functions from and just hand-code your own fix_heap(first, l…

    On a related note, if you’re around Washington, DC in the US, then the National Cryptologic Museum[1] is well worth a visit. They have a ton of equipment on exhibit, including a va…

    If you are accessing elements in memory with a constant stride[1], then hardware prefetchers[2] do a surprisingly good job at “reading ahead” and avoiding cache misses. A typical e…

    Somewhat tangential, but did Nvidia ever confirm if they cancelled their project to develop custom cores implementing the ARM instruction set (Project Denver, and later Carmel)? It…

    Ask HN: Why do message queue-based architectures seem less popular now?

    In the late 2000s and early 2010s, I remember seeing lots of hype around building distributed systems using message queues (e.g. Amazon SQS, RabbitMQ, ZeroMQ, etc.) A lot of compan…
