Repair of sabotaged mathematical glyphs in certain Linux distros.

Recently, I received a tip that some Linux users saw rubbish in place of certain Unicode glyphs appearing in the FFA series (in particular, in Ch. 14.) If the following two rows of symbols do not appear recognizably-identical in your WWW browser: ← → ⇠ ⇢ ⌊ ⌋ … the following fix is likely to […]

Defeating Vendor Lock-Ins: "Liebert GXT4."

Certain double-conversion UPS units by Liebert (in my case — a GXT4-2000RT120) appear to contain a boobytrap whereby off-the-shelf (needs two 12v/80mm) high-efficiency/quiet fans will not operate — the boot will abort with a Fan Out of Order error. The pill: install a 100 ohm wirewound resistor in parallel with the front fan connector (on […]

"The Advantages of a Dragon."

Lately, I found myself unable to resist the temptation to translate this very pertinent classic of science fiction to English. If you, reader, know of a better translation, do not hesitate to write in. Meanwhile, here goes: “The Star Diaries of Ijon Tichy: The Advantages of a Dragon.” Stanislaw Lem (1921-2006). Until now, I’ve said […]

Regarding VPNism.

In the spam trap today, I turned up this piece of “fan mail”: Good afternoon there, I became even more concerned about our future after reading your http://www.loper-os.org/?p=1299 page. Our government continues to use surveillance technologies to collect sensitive data and then there’s a real risk that this data can be leaked. Did you know […]

The Serpent Cipher's Key Schedule Equation System, in Graphical Form.

This article is a continuation of the dig into the key schedule of the Serpent cipher. For clarity, we will omit the routines already given in the previous article. Let’s visualize the Serpent key schedule as a graphic: ;; 256bit(key)+1(const) x 4224(132*32) matrix, last column for constant subterms (defvar *matrix* (make-array ‘(257 4224) :element-type ‘(mod […]

Linux. (1991 - 2018)

Linux. ( 1991 — 2018. ) No disrespect is intended for Stepan Mitrofanovich Gudimov (1913 – 1941), died heroically in aerial ramming maneuver… whose beautiful tomb I stole here. But IMHO a dead project of Linux’s stature deserves a tomb, even if only an imaginary and stolen one. Especially a stolen project…

The Google H1 Fritz Chip.

Edit: Step-by-step replication instructions for the skeptical experimenter. This article is a review of what I have been able to discover regarding the Google H1, aka Cr50, aka the “G Chip”, found in all Chromebooks of recent manufacture, including the Asus C101PA, my current candidate for a full delousing attempt. To my knowledge, there has […]

Open Problem: Delousing the Asus C101PA.

Apr. 26 update: This article is obsolete, the pill — was found; if you have this machine, scroll to the end. The Asus C101PA Chromebook is a very interesting device: it contains a Rockchip CPU, for which we already have a working deloused Gentoo; it also contains such marvels as a non-blobulous Marvell 802.11 card, […]

The Peculiarly Quiet Decline and Fall of the KVM

Yes, that familiar little PC peripheral. The one that toggles a single keyboard/mouse/display ensemble between two or more connected machines. They’ve quietly vanished from the market. And the fact appears to be discussed nowhere on the Net, at all. So I have seen it fit to make a note of it here. What’s this, you […]
