How to Make Your Own Lamport Parachute from Common Household Materials.

The thought began, as many good things begin, in #trilema.
Users of the WOT, of V, and other systems where your cryptographic identity is wholly in your own hands1 live with a certain risk of “cryptographic death” – i.e. the compromise of one’s signing key. A conscientious user of public key crypto might keep the thought [...]

A Complete Pill for the Sage SmartProbe.

Note: Please read the FAQ!!!
The Sage SmartProbe was a very spiffy “Hard ICE” debugger, one of the few ever manufactured for use with modern (2010s) AMD x86-64 processors, and – as far as I’m aware – the only one ever sold on the mass market, rather than as part of “favourite son” deals (as, e.g., [...]

Mechanics of FLUXBABBITT.

The public discovery of FLUXBABBITT, a modestly-clever American spy gadget – that may or may not have been “fired in anger” yet – has provoked the usual flood of media garbage (“JTAG is a Chinese back door! Threat or menace?”) What follows is some basic investigation regarding the plausible workings of this device, based only [...]

Wanted: FLUXBABBITT.

By now, I imagine everyone with the slightest inkling of an interest in electronics has seen this scandalous tidbit:

To anyone who has received this generous gift from his Government, I offer:
4 Bitcoin for either of the above, in working condition. 1 Bitcoin for a dead or untestable unit.
Serious inquiries only! Please attach two high-res photographs [...]

You are Bad at Entropy.

Presenting a very old game, entitled: Man vs. Machine. Or, why Man is not a Particularly Good Source of Entropy.

The abbot smiled. “No one should. [...]

RIP Douglas Engelbart.

Douglas Engelbart – perhaps the last of the great American inventors – is dead. The newspapers are keen to remind everyone that Engelbart invented the computer mouse, but they are largely silent on the matter of his having personally created almost every one of the concepts we think of as part of the standard [...]

MicroWriter Redux.

I have decided to publish some of my “archaeological” work from last year on Cy Endfield’s MicroWriter.  The original objective was to produce a cycle-accurate emulator.  I do not currently have the free time to complete this project, so I will post my results here for anyone who might care to pick up the torch.

Why Hypercard Had to Die

Update: Click here if you would like to try HyperCard yourself.
I was a Hypercard child – though our friendship was brief.
Our seventh-grade class was led into a room full of brand-new Macintosh Performas.  The day’s lesson was a crash course in the use of an uncomplicated yet marvelous program. With it, one [...]
