1 | 2 | Next2 Citations littleBits, a growing library of preassembled circuitboards, made easy by tiny magnets!littleBits is an opensource library of discrete electronic components pre-assembled in tiny circuit boards. Just as Legos allow you to create complex structures with very little engineering knowledge, littleBits are simple, intuitive, space-sensitive blocks that make prototyping with sophisticated electronics a matter of snapping small magnets together. With a growing number of available modules, littleBits aims to move electronics from late stages of the design process to its earliest ones, and from the hands of experts, to those of artists, makers and designers., blogmarks.net

RANDOM.ORG - True Random Number Service 1 Citation RANDOM.ORG offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs., blogmarks.net

1 Citation I recently discovered memcached which is a distributed, object caching system originally developed by Brad Fitzpatrick of LiveJournal fame. You can think of memcached as a giant hash table that can run on multiple servers which automatically handles maintaining the balance of objects hashed to each server and transparently fetches/removes objects from over the network if they aren't on the same machine that is accessing an object in the hash table. Although this sounds fairly simple, there is a lot of grunt work in building a distributed object cache which handles data partitioning across multiple servers and hides the distributed nature of the application from the developer. memcached is a well integrated into the typical LAMP stack and is used by a surprising number of high traffic websites including Slashdot, Facebook, Digg, Flickr and Wikipedia. Below is what C# code that utilizes memcached would look like sans exception handling code, blogmarks.net

1 Citation Application Programming Interface, a phrase that has a number of different meanings to the people build and use APIs, and virtually no meaning at all to those that don't. I like to think of an API as a bridge - one which allows information to flow from one piece of software to another. In the case of the Guardian's Content API, the bridge allows us to send requests to and receive information from the Guardian's huge database of articles, images, and other assets., blogmarks.net

Milk Bottle LED Lights, Arduino Controlled 1 Citation Make PPE milk bottles into good looking LED lights, and use an Arduino to control them. This recycles a number of things, mainly the milk bottles, and uses a very low amount of power: the LEDs apparently dissipate less than 3 watts but are bright enough to see by!, blogmarks.net

UrbanTick: What shape are you? 1 Citation Wile working with the GPS track data of the UrbanDiary project, in connection with the series of interviews I am conducting, I suddenly recognized the different shapes and patterns that are being produced by the participants. Really funny shapes and forms, but always with a number of strong fix points. The shape is determined by a number of factors such as the spatial relationship of destinations, the distances traveled, the amount of travel and the intensity of repetition. The first point, relationship of destinations makes for the overall shape and the last point, the intensity of repetition makes for the character of the shape.The images are all generated from participants that have a track record of two month and are the same scale., blogmarks.net

1 Citation Abstract Brands are important in the consumer market. They are the interface between consumers and the company, and consumers may develop loyalty to brands. This study proposes that trust in a brand is important and is a key factor in the development of brand loyalty. Factors hypothesized to influence trust in a brand include a number of brand characteristics, company characteristics and consumer-brand characteristics. Respondents representing a broad spectrum of Singapore consumers were surveyed. The findings reveal that brand characteristics are relatively more important in their effects on a consumer's trust in a brand. The results also show that trust in a brand is positively related to brand loyalty. Marketers should, therefore, take careful consideration of brand factors in the development of trust in a brand., blogmarks.net

code, circuits, & construction :: Writing to Mifare RFID tags 1 Citation Mifare RFID tags, like other RFID tags, contain a serial number that can be read using an RFID reader, but they also have a limited amount of memory space that you can write data to, and read back from. This can be handy if you want to do something like keep a user?s account balance or name directly on the RFID tag., blogmarks.net

1 Citation Easy, says Sapolsky. Let's say 10% have done this taboo sexdeed, 90% haven't. Tell your subjects that those who have done the taboo sexdeed should answer the question honestly, ie confess to it. Add that those who haven't done the taboo sexdeed should toss a coin. If it comes up heads, they should say they have done the sexdeed, whether they really have or not. If it comes up tails, they should say they haven't, again regardless of what they've actually done.This randomizing process will allow the people who have done the taboo sexdeed to confess it, knowing that they have an alibi, should they be challenged, in the shape of the coin. As long as they understand the rules, everyone who did the taboo sexdeed should confess. The researcher then just needs to double the number of people who say they haven't done the non-taboo deed -- everyone else has done the taboo deed., blogmarks.net
