Interesting article about the HTML mark element and how to use it with org-mode.

One of many interesting articles. See https://xeiaso.net/blog/2024/homelab-v2/, https://xeiaso.net/blog/idk-about-email/, https://xeiaso.net/blog/push-2fa-considered-harmful/ for others.
On https://xeiaso.net/blog/move-away-rsa-ssh/, it is stated that "[it is] likely you can break 2048-bit RSA (the most widely deployed keysize) with a quantum computer that only uses 372 qubits of computational power. The IBM Osprey has 433 qubits."
https://12factor.net/ sounds interesting too.

Elaborate setup for blogging with Emacs, org-mode, Jekyll and Github actions. Too complicated for my taste, but I still might learn something from the description.

Sail is a language for defining the instruction-set architecture (ISA) semantics of processors: the architectural specification of the behaviour of machine instructions. Sail is an engineer-friendly language, much like earlier vendor pseudocode, but more precisely defined and with tooling to support a wide range of use-cases.

Some results are reported in https://joshondesign.com/2022/09/21/idealos_mark6, but it seems more like a (slow) prototype.

The description below sounds intriguing.
In numerical analysis, the ITP method, short for Interpolate Truncate and Project, is the first root-finding algorithm that achieves the superlinear convergence of the secant method[1] while retaining the optimal[2] worst-case performance of the bisection method.[3] It is also the first method with guaranteed average performance strictly better than the bisection method under any continuous distribution.[3] In practice it performs better than traditional interpolation and hybrid based strategies (Brent's Method, Ridders, Illinois), since it not only converges super-linearly over well behaved functions but also guarantees fast performance under ill-behaved functions where interpolations fail.[3]

Common Lisp program trying to map between Unix and Lisp concepts.

This section of the site offers RF engineers quick access to popular calculators and design aids. They are useful at design time and for training purposes, both of which stimulated their development and use over the years. Each tool is written in Javascript and the user can view the page source should they wish to examine the implementation.

I have tried to include references to the various books/papers that I have used in the development of each tool and although I have used them all at various times and believe them to be accurate, please use due diligence and further simulate where necessary.

Most of the tools come with sample values pre-entered into each input box to offer a degree of help. I apologise if this bothers you, but from the feedback I receive, it is generally preferred.

Please be sure to have read the "terms of use". The link is available at the bottom of every page.

The references look interesting.

The Language-theoretic approach (LangSec) regards the Internet insecurity epidemic as a consequence of ‘ad hoc’ programming of input handling at all layers of network stacks, and in other kinds of software stacks.  LangSec posits that the only path to trustworthy software that takes untrusted inputs is treating all valid or expected inputs as a formal language, and the respective input-handling routines as a ‘recognizer’ for that language.
The recognition must be feasible, and the recognizer must match the language in required computation power.
