Then there is the "1 bit" microprocessor that has two instructions: "NOP" and "HALT"

Large Hadron Rap
This is an evergreen which dates back to 2008, when this huge experiment was set up at CERN, to find the presence of antimatter... I came again into this some hours ago... And I had to republish this, along with its text and a translation for my fellow Italians... :)
(by the way, alongside there is a second experiment, which demonstrates why scientists should never try to play as showmen... :))

Intercepting Keystrokes in any Application
This post is about one simple question: is Windows' software secure?
The answer is: no, it's not.
In the next few lines, I will show you how to easily write some code which will allow you to intercept text which is being typed into any other application! In particular, I will illustrate how to write a simple dll which will delete any lowercase vowel typed by the user...
And yes, this is one of the techniques behind keyloggers...
Since these are multimedial days, here there is a video showing how this dll can interact with a common application (Microsoft Word):

Pippo e le metavariabili
Qualsiasi programmatore si scontra, neanche troppo tardi, con la necessità di spiegare qualche algoritmo a qualche amico.
Se eccettuiamo casi di alto livello (come algoritmi sui grafi, o sui flussi, o di programmazione dinamica), il metodo migliore è quasi sempre partire dal codice.Ed immediatamente, ecco che ci si imbatte in qualche variabile d'appoggio, di cui capiamo perfettamente il senso, ma a cui non sappiamo che nome dare...
Ed ecco quindi che, qualsiasi programmatore, ricorre agli stra abusati pippo, pluto, ciao, mamma, o che dir si voglia...
Queste variabili sono chiamate variabili metasintattiche. Una variabile metasintattica è un nome usato per indicare un generico elemento all'interno di una determinata categoria; l'uso è analogo a quello che in matematica si fa del nome x o y e z per indicare tre valori o tre variabili qualsiasi; oppure, in numerosi contesti, all'uso di Tizio, Caio e Sempronio per indicare tre generiche persone.
