About metaobject

Working as a software engineer using C, C++, Python, Scheme on simulation and optimization tools and applications in the meterology/satellite data processing/atmospheric sciences domain. I'm fond of the Lisp family of languages, and am currently working on Scheme-bindings for our modeling, simulation, and analysis tools.

    That’s just recursion

    I think the “fringe” comes from the theory that cosmic inflation occurred before the BB

    Perhaps he just meant IR sensors? Also, I wonder whether UV sensors would be helpful.

    Do you even know what “free speech” means?

    IIRC, the US Army Corps of Engineers also built/repaired the levees in New Orleans in the wake of Hurricane Katrina.

    Language implementation-wise, can anyone explain why/how Julia is able to get close to C-level performance? Is it doing some extra steps under the hood (JIT compilation?) that Pyth…

    Sometimes I lay in bed at night thinking about the deficiency I haven't had time to address or that isn't a current priority, or the obscure bug I found a while ago that is laying …

    I'm going to guess and say he was just borrowing a current, in-the-news hashtag and applying it to this situation. In other words, he was just joking around.

    For me, it's when I open my .emacs file and start working on my personal TODO items. The last time I ended up writing some elisp functions to make adding code comments/documentatio…

    Regarding the "smearing" concept, how does that square with the formation of neutron stars and white dwarfs? Those objects are incredibly dense because they're composed mostly (?) …

    I guess I'm just shocked that the surgeon could offer that level of assurance about something like that.

    Why would previous versions of Python3 (e.g., 3.5, 3.6) not perform as well as 2.7? What about Python3 makes it slower? Is it a language design issue? We’re in the process of migra…

    Using a web app requires one to upload their file 100% of the time. Using a local app requires one, I'd expect, to upload their file 0% of the time.

    I really don't understand the hate for Musk. Shit, a lot of these projects are really experiments that he's funding. They're really cool experiments, at that, and experiments aren'…

    Also, you need to have a cloud-free line-of-sight to the satellite.

    Besides being much newer (and lighter components are now available), the electronics for a Free Space Optical system are much lighter than the electronics for an RF system. The con…

    I wouldn't call myself proficient in Java, but I understand the basics. I'm a C and C++ programmer at heart, so the few times that I had to write new Java code back in the day I al…

    Very clear presentation. Helpful diagrams. Clean code. This has a very “Linkers and Loaders” (John Levine) feel to it. Very well done.

    Dark matter is also believed to be what holds galaxies (and galactic clusters) together by enveloping them in what are called dark matter halos. https://en.m.wikipedia.org/wiki/Dar…

    AFAIK, we are unable to see the center of the galaxy with visible-spectrum sensors due to the immense amount of dust and gas. We can see the center with IR sensors, however.

    Although modern usage of the word “hacker” has been applied to non-software contexts, I’ve also seen the term “maker” used here as well.
