  1. Physics-Informed Neural Surrogates for Mesh-Invariant Modeling of High-Speed Flows at !

    High-speed flight simulation is computationally brutal. A single CFD run can take hours on a cluster. That's fine for final validation, but not for early design exploration or real-time decision-making.

    Neural surrogate that predicts aerodynamic behavior 595x faster than CFD while maintaining ~1% relative error.

  5. Well. Getting Tomcat 9 running on an ultra-cheap Amazon EC2 instance (with Amazon's very own ARM chip) running Ubutuntu 24 and accessible from my home PC when you barely know wtf you're doing might not sound like much of an achievement, but it is for me, and here I am, patting myself on the back.

  6. The problem of building neural surrogates for real-world industrial problems is not a problem of choosing neural network architectures, it's a problem of gathering the right training data from the model you're seeking to emulate. We demonstrate this on a turbofan jet engine, achieving 0.1% relative error through an active learning process. This is one of the demonstrations from showcasing the advancements of industrialization of

  7. emacs org-mode todo list priority (urgency) hack

    Might as well brag about this, since I’m inordinately proud (I become an #elisp hacker about once every two or three years). I love #emacs #org-mode, but I don’t love what it does with todo entries (highest-priority, longest-scheduled first). For me, if something’s been at priority A for 280 days, it’s not that high-priority (but still higher than anything at priority B). I want highest-priority, most-recently-scheduled first, in the time-honored tradition of ignoring things in the hope they’ll go away.

    Here it is.

    (defun my-org-agenda-todo-sort (a b)  "Function should only sort TODO items; since I can't return ``unsortable'' for things that don't compare, I justreturn 0 and hope for the best.  Seems to be working so far.  Higher-priority and more-recently-scheduled itemshave higher urgency."   (if (string-match "\\(Sched\\.\\s-*\\([0-9]+\\)x\\|Scheduled\\):\\s-+\\S-+ \\[#\\([ABC]\\)\\]" a)      (let ((a-sched-days (string-to-number (if (null (match-string 2 a)) "0" (match-string 2 a))))            (a-priority (match-string 3 a)))        (if (string-match "\\(Sched\\.\\s-*\\([0-9]+\\)x\\|Scheduled\\):\\s-+\\S-+ \\[#\\([ABC]\\)\\]" b)            (let ((b-sched-days (string-to-number (if (null (match-string 2 b)) "0" (match-string 2 b))))                  (b-priority (match-string 3 b)))                                        ;(message "Agenda item a of type %s: %s" (type-of a) a)                                        ;(message "Agenda item b of type %s: %s" (type-of b) b)                                        ;(message "a-priority: %s; b-priority: %s; a-sched-days: %s; b-sched-days: %s"                                        ;         a-priority b-priority a-sched-days b-sched-days)              (cond ((string< a-priority b-priority) 1)                    ((string> a-priority b-priority) -1)                    (t (cond ((< a-sched-days b-sched-days) 1)                             ((> a-sched-days b-sched-days) -1)                             (t 0)))))          0          )        )    0    )  )(setq org-agenda-cmp-user-defined 'my-org-agenda-todo-sort)(setq org-agenda-sorting-strategy '((agenda habit-down time-up user-defined-down category-keep)                                    (todo urgency-down category-keep)                                    (tags urgency-down category-keep)                                    (search category-keep)))

    It has a name as well!

    'Li-Ligh' which is acronym for 'Left India, Landed in Green Head' 😀

  11. Excited to head back down to LA tmw for the #scitech #Oscars. No, I’m not nominated, just getting to sub in for a friend’s spouse.

    Always a privilege to get to attend and share the joy of my compatriots in this space I’ve spent my adult life working in - making movies!

  12. Last #undersea #Internet #cable connecting #Vietnam with the world breaks down | #SciTech | Vietnam+ (#VietnamPlus)

    "The #SMW3 cable, the last fully functional Internet cable of Vietnam, has encountered a problem on its S2.7 segment that connects with #Singapore, an Internet service provider in the country said on February 21.
    This means all the five undersea cables connecting Vietnam with the world have been partly or wholly affected."

  13. I'm refraining from opining/judgment on this one until there's experimental data pointing some way or another, but hopefully I'll be able to hear more at next week.
