One of my favourite features of Fortran is in its array implementation. You can index arrays however you like. Do you like your initial value to be at index 1? Cool. Prefer to index arrays from 0 instead? Sure, go ahead. How about an array

Since this is using fetch/XHR under the hood, I guess requests from the browser are restricted only to same-origin URLs or servers responding with permissive CORS headers?

Perhaps Illumos is particularly well suited for a Hypervisor/Cloud platform due to work upstreamed by Joyent originally for SmartOS?

I love my lava lamp. I use it as the light for my bedside table. I’m too young to have seen the craze the first time around, but for me they are the ultimate nostalgia object. You see, lava lamps take me back to being a young child visiting

There’s a non-paywall version on arXiv: https://arxiv.org/abs/2308.09083 The paper you mention is indeed cited.

It can happen, the Pólya conjecture is the usual example which holds until n = 906150257. Another fun one I just found is the statement “n^17 + 9 and (n + 1)^17 + 9 are relatively prime”. The first counterexample is at n=8424432925592889329

You can’t have a post about SDF without linking to iq’s incredible articles [1]. See also “Rendering Worlds with Two Triangles” [2], which is such a wonderful title for describing these techniques. [1] https://iquilezles.org&#x2F

If a rebase goes wrong and you want out you can run, git rebase --abort to return to where you were beforehand. I find that git is actually very good at explaining what is going on and what you should do next by just running git stat

Probably not DOOM, but apparently some microSD cards have microcontrollers that can be exploited to run arbitrary code: https://www.bunniestudios.com/blog/?page_id=3592

Thank you so much for this! I have been so infuriated the last couple of months with persistent issues like Mail closing and Safari’s cache randomly being purged, losing many website’s login sessions. Two-factor authentication multiple time

Interacting with this website induced terror in me. Even accepting the use of cookies cost coins! Yes, it's making a strawman argument, but think of it like an interactive horror story. It sparked an emotion and for me that makes some

I too would have liked to have seen Navier-Stokes included, or least an inviscid Euler equation for modelling fluid flow.

This repo mentions that threaded code is often used in Forth implementations, amongst other things. One of the best descriptions of threaded code and how Forth works in general is the Jonesforth[1] source code, written in a literate program

As far as quantum gravity theories go I’m personally quite partial to Causal Dynamical Triangulation [1] [1] https://arxiv.org/pdf/1905.08669.pdf#page79

I’ve worked with several Fortran projects before. Modern Fortran is actually quite nice to work with once you get into the swing of it. I think the language itself and the surrounding tooling aren’t really causing the image problem. The rea

If you like that simulation you might also like my own webGL Gross-Pitaevskii Equation (GPE) solver. It uses RK4 to simulate a 2D box of ultracold atoms undergoing Bose-Einstein Condensation. The GPE models a condensate as a single-particle
