Phuctor: Fun with Public-key Cryptography.

All of my readers are invited to test the security of their GPG public keys using a new and very simple online tool: “Phuctor” (part of a long-term collaborative project with Mircea Popescu.)
Phuctor is based on cutting-edge Ancient Greek technology.

A Country of Which Nothing is Known but the Name.

If you came here via a search engine, you were probably looking for Pierre Cartier’s wonderful mini-biography of the mathematician Alexander Grothendieck – from which I shamelessly stole the title. Please go straight there. Otherwise…

“And so no one, except for two people, enters the top floor of the Aedificium. …”
The abbot smiled. “No one should. [...]

Don’t Blame the Mice.

Your kitchen is alive with vermin! Who is to blame? The cruel forces of nature? Or, might it be you – the fellow who scattered delicious crumbs everywhere; spilled honey a thousand times without picking up a mop once; and kept a mountain of old newspapers around for rodents to chew into nest liner?

“I can’t assure with 100% certainty that the all the black dots are owned by Satoshi, but almost all are owned by a single entity, and that entity began mining right from block 1, and with the same performance as the genesis block. [...]

“The most important thing a crook needs is an impeccable reputation.”
(Attributed to Agatha Christie.)

Bitcoin interests me as an obvious example of a technological jewel tossed around aimlessly by the brutal hands of cave men. I can’t help but picture a flashlight or a radio set, left behind in the wilderness by geologists, to be [...]

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.

On the fact that Bitcoin has a Kill Switch; and how to disconnect it.

“There are three classes of people: Those who see. Those who see when they are shown. Those who do not see.”
(Attributed to Leonardo da Vinci.)

Bitcoin, or How to Hammer in Nails with a Microscope.

“The enlightened, disciplined mind is the holiest of holies, a wonder among wonders. Upon the Earth – a grain of sand in the Universe, man is on the order of one-billionth of the smallest magnitude… And yet this particle in your mind’s eye, that lives but for sixty or so trips of [...]
