| Lisp interpreter in 90 lines of C++ | |
| I've enjoyed reading Peter Norvig's recent articles on Lisp. He implements a Scheme interpreter in 90 lines of Python in the first, and develops it further in the second. | |
| Just for fun I wondered if I could write one in C++. My goals would be | |
| 1. A Lisp interpreter that would complete Peter's Lis.py test cases correctly... | |
| 2. ...in no more than 90 lines of C++. | |
| Although I've been thinking about this for a few weeks, as I write this I have not written a line of the code. I'm pretty sure I will achieve 1, and 2 will be... a piece of cake! |

| module NumericTests |
| Simple demonstrations of putting AVR microcontrollers to sleep in power-down mode, | |
| which results in minimum current. Coded with Arduino IDE version 1.0.4 (and with | |
| the Arduino-Tiny core for the ATtiny MCUs, http://code.google.com/p/arduino-tiny/) | |
| For ATmega328P, ~0.1µA. | |
| For ATtinyX5 revisions that implement software BOD disable, ~0.1µA, | |
| for ATtinyX5 revisions that don't, ~20µA. |

Software components used:
| // Just before switching jobs: | |
| // Add one of these. | |
| // Preferably into the same commit where you do a large merge. | |
| // | |
| // This started as a tweet with a joke of "C++ pro-tip: #define private public", | |
| // and then it quickly escalated into more and more evil suggestions. | |
| // I've tried to capture interesting suggestions here. | |

Macri: Pobreza 0. Hace 4 años que no crece, hay que crear trabajo. Plan de infraestructura más importante de la historia, que conecte la argentina y desarrolle las economías regionales, generando 2.000.000 de puestos de trabajo. Créditos a 30 años para primera vivienda. Cloacas, agua corriente. La Asignación [Universal por Hijo] se extienda a todos, incluyendo hijos de monotributistas. Plan Primer Empleo, cinco primeros años sin impuestos para empleado ni empleador.
Scioli: Macri va a levantar el cepo, liberar el tipo de cambio, representa un recorte en el salario real. Abrir la economía es un peligro para el conjunto. ¿Quién va a pagar los costes de este ajuste?
