The V Public License.

Recently, I learned that at least one of my readers is dissatisfied with my current favourite “open source license”. For him and any others like him, I would like to propose a new one, and offer to “relicense” under it any of the VTronic items I have published on my site (strictly by explicit request, […]

The Three Reasons For Source Code Publication.

There are innumerably many reasons for writing a computer program; but, to my knowledge, the publication of its source code is nearly always motivated by one of these three: I. Subordination: “Open Source.” Some of the earliest — and arguably, highest quality — computer programs with openly-published source code were developed inside conventionally-structured organizations, by […]

"Pest" v. 0xFB.

This is a continuation of “Pest” v. 0xFC. This is the heaviest revision of the spec to date, approaching a total rewrite. Pedantic details concerning data types and their encodings were added; several algorithms have been reworked and substantially simplified; and a number of ugly gaffes — corrected. There is a pretty-printed mirror of this […]

"Pest" v. 0xFC.

This is a continuation of “Pest” v. 0xFD. There are currently two published prototype implementations of Pest: “Blatta” (by thimbronion); and “smalpest” (by jonsykkel). Thank you, prototype implementers! A quite lively Pestnet is now active, and a public log thereof, operated by billymg (WOT) may be seen here. There is a working draft of v. […]

"Pest" v. 0xFD.

This is a continuation of “Pest” v. 0xFE. There is a pretty-printed mirror of this page. There is now a prototype! (Thank you, thimbronion!) 14 Dec 2021: And there is now a second prototype! (Thank you, jonsykkel!) There is a working draft of v. 0xFC. (Note: it may change without warning!) The document (very much […]

"Pest" v. 0xFE.

This is a continuation of “Pest” v. 0xFF. Edit: A note for the innocent — this series of articles concerns an algorithm! It is not, at the time of writing, fully implemented anywhere! There is now a prototype! (Thank you, thimbronion!) Or even entirely complete. Edit: There is a working draft of v. 0xFD. (Note: […]

"Pest" v. 0xFF.

What follows is a long-promised detailed specification of a DDOS-proof, CPU-inexpensive, ciphered-authenticated peer-to-peer communication protocol. I would like to thank Thimbronion for implementing a large subset of this spec already despite not having seen it yet! The document (very much a work in progress!) is available as a vtree. You will need: A V-tron. If […]

The Fossil Vault.

I have recently built two new WWW mirrors containing certain publicly-available software: 1. Historic Gentoo Distfiles. I have been using Gentoo for nearly all Linux-related work since 2007. It was “the lesser of evils”: to my knowledge, no other Linux variant ever offered a comparable level of rodenticidal control, while at the same time providing […]

25 Years of Loud, Expensive Space Heaters.

A half-written draft of this piece has been living on my HDD for nearly half a year. Recent discussions re: the subject of “aging and death of PC irons” prompted me to dust it off and quickly post. Regularly-scheduled programming will resume shortly… “The tools, the means and the methods disappear under the overwhelming dead […]

The Serpent Cipher’s Key Schedule Transform is Injective.

This article is a continuation of the previous, and concludes the series. Let’s try this somewhat different variant of the program, which represents recurring bits of the expansion symbolically (and in a slightly more readable form) : ;; Register bitness. (defconstant +bitness+ 32)   (defun make-reg (reg-name bitness) "Make algebraic representation of a register (bits […]
