The cryptographic currency Bitcoin [Bitcoin.org], has been in the news lately.  It has become the most successful open source peer to peer digital currency to date.  It is a valuable enough form of exchange that governments have held meetings regarding whether it threatens their currencies, and thieves have successfully hacked in to exchanges to steal Bitcoins [Wired].

The exchange method is complicated and tends to be glossed over by the media.  Michael Neilsen has written a very good, understandable (to engineers) description of how the mathematics work [Neilsen Bitcoin].  Integrated circuits are now widely used to mine bitcoins [mining].

Bitcoin can be exploited.  The monetary incentive to uncover weaknesses in Bitcoin has also revealed weaknesses in the widely used OpenSSL [Arstechnica]. 
Small Linux

There are many light weight Linux ports which are small, fast and suited to embedded systems. A large list can be found here: [lightWeightLinuxWiki]  

   Embedded microcontrollers: uC Linux [uclinux.org] has been ported to: DragonBall, ColdFire, QUICC MC68EN3xx; Hitachi H8; ADI Blackfin; ETRAX, ARM7TDMI, Intel i960, PRISMA, Xilinx Microblaze, NEC V850E, and more.

   Tiny Computer Boards: Lightweight Linux systems run on PCs, the raspberrypi , the mk802, beagle board, and many more.

   PCs: You can quickly turn an old, slow PC into super fast machine in about an hour (including the learning curve) using a RAM based OS, such as Slacko Puppy Linux [slackoPuppy]. The drivers for the peripherals and wireless networking are automatically installed and become operational immediately.  

CEPD is growing

In 2013 CEPD added three new full-time Engineers! We hired two experienced Engineers, and we converted our intern of over a year to full time after he earned his BSEE. We brought in a new engineering intern to fill the missing slot. We have expanded our base of subcontractors as well, so that we can increase staffing as needed to handle more and bigger projects, and to add targeted expertise to our broad skill set. Please help us welcome our new Engineers by continuing to give them challenging work to do! 

Society News

In April, the IEEE smaller societies plan to introduce the first Dine and Learn event.
The goal of Dine and Learn is to provide an opportunity for people in our community to join for drinks, food, and a technical presentation on a regular basis and help reduce the overhead for smaller societies.
Stay tuned by visiting the IEEE Signal Processing Society's website:[IeeeDenverSPS]
