The following circuit is the well-known infinite ladder network, constructed by repeatedly adding a series impedance Zs and a parallel impedance Zp. The reader may question the usefulness of such a circuit, which appears to possess the sole purpose of nerd-sniping. While this is indeed its common usage, but it does have quite a few practical applications. Physically, a discrete circuit has a finite number of elements and is governed by Ordinary Differential Equations, while a distributed circ...| Posts on niconiconi's blog
On AMD GPUs, the feature XNACK is essential for running HIP code with Managed Memory. But what XNACK does, or how can it be enabled, is poorly documented. I believe this article is the only comprehensive guide on the entire Web.| niconiconi.neocities.org
On iOS, background audio autoplay is disallowed, users are not even allowed to add exceptions. Thus, many existing Web apps and games - WebAssembly apps in particular, are incompatible with iOS without modifications. Fortunately, iOS 15 (late 2021) started to allow browser extensions, including Userscripts. To overcome this problem, a Userscript has been developed to intercept Web Audio contexts and inject a "Start Autoplay?" pop-up window into the page, enabling otherwise incompatible games ...| niconiconi.neocities.org
A method of cross-compiling FORTRAN code to WebAssembly with LLVM and flang is described. only numerical computation is supported, standard library currently cannot be used. In spite of this limitation, it already enabled a non-trivial practical application: cross-compiling the TNT-MMTL 2D electromagnetic field solver to WebAssembly, allowing electronics designers to solve microwave transmission lines using the Boundary Element Method (BEM) without leaving the Web browser.| niconiconi.neocities.org
