About tobmlt

I wrote an automated geometry design/generation tool for my PhD. A bit of nonlinear optimization and constraint programming with a natural (math) interface for writing constraints. Some other goodies.

I really like discrete differential geometry and what aspects of differential topology I’ve been able to get hold of so far. I enjoy writing computational code (cfd, time unsteady motions, design generation/optimization, mostly) and am enamored with the idea of symmetry preserving integrators, and the like.

I currently work on software for computational analysis and design.

    fuck me. I have had ridiculous insomnia since 2020. I have had tinnitus on and off since 2015/16 Incidentally this is also when my insomnia first showed up.

    This reminds me of something I remember from college but cannot ever seem to find: "The Jevon's diagram" by which I mean a two country system, with country containing two groups: h…

    Hey thanks. Reddit could be your friend here. Well, honestly, youtube as well. Here's a good, to the point summary of a lot of things: https://www.youtube.com/watch?v=vgH_9Iy7_mQ (…

    Great idea. Here is something that could be similar but more niche (sorry if too niche): join a meetup group for that does indoor rock climbing. If, say, meetup is a big thing wher…

    I've always imagined Feynman making a QED, QED joke sometime in the late 1940's for this very reason. Like he could end his Shelter Island Conference talk with the joke and then lo…

    Great stuff! I am in awe of your beautifully done graphs. For speed with, e.g. matrices like you say, but also more specialized course specific notation, could you build a set of q…

    Experiences vary. I was just at the point of qualifying exams when a full time job op came up in a tightly related field. They (profs and managers all) understood, my new co-worker…

    This should be a proxy measure for inflation. (If only it was quantifiable so easily…) Instead of prices going up in this case, quality goes down.

    Give me a neural lace with which I can stop a knife missile, or contact which stops the figurative knife missile forever, and so am I.

    This thread makes me wonder how many knife-missiles the USA has in stock. (I am using the opportunity to reference the fact that the USA indeed has a “knife missile” and it is simi…

    No clue. Octave is here for us… so at least we can run their code and ask any pertinent questions to expedite the port. ;) (Yes I know it’s simulink for many, but I’ve met some pur…

    The barrier to entry to doing fast linear algebra from scratch is the lowest of any of c,c++,Fortran. Python and matlab being to slow at “low barrier to entry level” for sure anywa…

    Modern Fortran has oop with one major design mistake: They use % as the accessor instead of . (Yes I am joking around) ;)

    From the title, I thought it was going to be an article about the present day. Sort of a “surprise! -it’s right now” kind of feel, and then talk about the second quantum revolution…
