OLPC


The One Laptop Per Child Association, Inc. (OLPC) is a U.S. non-profit organization set up to oversee the creation of an affordable educational device for use in the developing world. Its mission is "To create educational opportunities for the world's poorest children by providing each child with a rugged, low-cost, low-power, connected laptop with content and software designed for collaborative, joyful, self-empowered learning."[1] Its current focus is on the development, construction and deployment of the XO-1 laptop.


The goal of the foundation is to provide children around the world with new opportunities to explore, experiment, and express themselves. To that end, OLPC is designing a laptop, educational software, manufacturing base, and distribution system to provide children outside of the first-world with otherwise unavailable technological learning opportunities.


OLPC lists five core principles:


  1. Child ownership

  2. Low ages. Both hardware and software are designed for elementary school children ages 6-12.

  3. Saturation

  4. Connection

  5. Free and open source

Digital Signature

A digital signature or digital signature scheme is a type of asymmetric cryptography. For messages sent through an insecure channel, a properly implemented digital signature gives the receiver reason to believe the message was sent by the claimed sender. Digital signatures are equivalent to traditional handwritten signatures in many respects; properly implemented digital signatures are more difficult to forge than the handwritten type. Digital signature schemes in the sense used here are cryptographically based, and must be implemented properly to be effective. Digital signatures can also provide non-repudiation, meaning that the signer cannot successfully claim they did not sign a message, while also claiming their private key remains secret; further, some non-repudiation schemes offer a time stamp for the digital signature, so that even if the private key is exposed, the signature is valid nonetheless. Digitally signed messages may be anything representable as a bitstring: examples include electronic mail, contracts, or a message sent via some other cryptographic protocol.

Self Made Man


Self Made Man, the statue I greatly admire and the principle I strongly believe. "... left to his own devices, man will use his god-given talents to be creative, productive, and prosperous. Using free will, he will better his own situation and that of those around him, thereby influencing in a positive way his own destiny..."

The “Self Made Man” is an original sculpture by Colorado artist, Bobbie Carlyle. Ms. Carlyle has graciously allowed Funding Freedom to adopt the “Self Made Man” as its symbol of self-reliance and the freedom philosophy. The powerful image of the rugged “Self Made Man,” chiseling himself out of a solid block of rock captures the essence of the freedom philosophy – that left to his own devices, man will use his God-given talents to be creative, productive, and prosperous. Using free will, he will better his own situation and that of those around him, thereby influencing in a positive way his own destiny. This captures the philosophy of Funding Freedom and that of our clients.

Domino Effect

The domino effect is a chain reaction that occurs when a small change causes a similar change nearby, which then will cause another similar change, and so on in linear sequence. The term is best known as a mechanical effect, and is used as an analogy to a falling row of dominoes. It typically refers to a linked sequence of events where the time between successive events is relatively small. It can be used literally (an observed series of actual collisions) or metaphorically (complex systems such as global finance, or in politics, where linkage is only a hypothesis).
