“Sometimes, at night, I dream about the boat.”

Below is an entirely unofficial translation of “Иногда ночью мне снится лодка”, by Alexander Pokrovskiy — an old sailor-turned-memoirist, AFAIK entirely unknown in the English reich.

On some nights, I dream about the boat. It is underway, beneath the water.
I dream about it after I’ve had a very tiring day.
The dream is [...]

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…

Lost Technology: The PQ3QI-01 Sunlight-Readable Display.

In the last quarter of the previous year, I got hold of a virginal (sealed OEM-crate) PQ3QI-01 sunlight-viewable LCD panel (and, after several unsuccessful attempts — an old box where it fits.) These marvels are long out of print but apparently still available, somehow, from the Chinese, at around 100 $ per.
If the backlight lamp [...]

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) [...]

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 [...]

Serpent Cipher’s Key Schedule in Algebraic Form: with Reduction.

This article is a continuation of the recent mega-puzzler concerning the experiment.

This variant will reduce the equations. We will omit printing the input matrix, for brevity. And so:

;; Register bitness.
(defconstant +bitness+ 32)
 
(defun flatten (l)

Terms -8…8 of the Serpent Cipher’s Key Schedule in Algebraic Form.

This article is a byproduct of the recent mega-puzzler concerning the Serpent cipher’s key expansion procedure.

Behold:

;; Register bitness.
(defconstant +bitness+ 32)
 
(defun make-reg (reg-name bitness)
"Make algebraic representation of a register (bits in descending majority)"

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 been no [...]
