I have provisioned a machine colocation rack for the exclusive use of The Most Serene Republic, as represented by the WoT L1 and L2. If you, reader, are not in this roster, you may safely skip this article.

An Inexpensive Machine Park, of Yet-Indeterminate Quality.

Oct. 16 edit: included name of the vendor being evaluated.

Today I had occasion to lease some local rack space in my town. Currently I will not mention the vendor by name here, as I do not yet know the quality of the service, but if it proves satisfactory, will reference the vendor in an appendix [...]

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.

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:
