Silicon Devices: Embedded Web Server Development kits from Parallax and XMOS
http://obriensilicon.blogspot.com/2010/11/parallax-propeller-embedded-web-server.html
Saturday, November 20, 2010. Embedded Web Server Development kits from Parallax and XMOS. XMOS: XC-2 - An XS1-G4 based Embedded Web Server running a phy Ethernet interface. The XMOS web server development kit - the XC-2 is an excellent piece of hardware that runs the 32-thread 4-core XS1-G4 processor with integrated communications switch. The kit ships with an implementation of an IP stack based on lwIP. With most of the hardware functions implemented in software in parallel XC. The web server from Paral...

Distributed Java: January 2011
http://distributedjava.blogspot.com/2011_01_01_archive.html
Java based concurrent software and strategies for Grid, Cloud and Clustered environments. Monday, January 10, 2011. Multiple Instruction Multiple Data. We need to start thinking about how existing and future Java API's will work with all the combinations of multiple data sets, multiple virtual machines, multiple physical hardware devices and multiple clients. The issues surround how we handle concurrent access, availability, synchronization, distribution and sharing of all these resources.

Distributed Java: Accessing multiple remote EJB 3.0 Session Beans via JNDI in an SE Client - Experiment
http://distributedjava.blogspot.com/2010/11/accessing-multiple-remote-ejb-30.html
Java based concurrent software and strategies for Grid, Cloud and Clustered environments. Tuesday, November 2, 2010. Accessing multiple remote EJB 3.0 Session Beans via JNDI in an SE Client - Experiment. This project is superceeded by the Collatz Distributed Java EE Application Tutorial. This code will run on both a Java SE client or an EE container like Oracle WebLogic. WebLogic RMI Client Configuration. Here we have a very simple JNDI client that acts as a hello world. The JNDI protocol uses t3. Statef...

KiloCore: January 2011
http://kilocore.blogspot.com/2011_01_01_archive.html
About Kilo core class custom processors or machines. Friday, January 7, 2011. The following designs are possible alternatives or successors to my existing hypercube or array processor designs. The data flows in a single direction in a pipeline or tree fashion where each core performs a single process on the dataset which is passed along to the next node(s). D2: Data Parallel Processor. This architecture is fine grained and usually assigns a single core to each data point for SIMD oriented user software.

OBrien Devices: How to use Clamp Meters : Agilent and Sperry
http://obriendevices.blogspot.com/2010/11/how-to-use-clamp-meters-agilent-and.html
Tuesday, November 2, 2010. How to use Clamp Meters : Agilent and Sperry. If you are like me, you need to measure electrical current (Amperes/Amps/A) so you can figure out the power used by your electronic circuits (Watts/W - or Volt-Amps/VA) - not to mention the power used by your toaster (a surprising 1 KW. You need a Clamp Meter! I currently use the Agilent U1211A. Therefore, to measure AC and indirectly DC current you plug in the line splitter into your 120V ac outlet and. The Agilent U1211A True RMS ...

Saturday, November 6, 2010. Combinatorial Parallel Logic Unit - Minimal custom Mesh Processor. This device consists of very simple logic processors (a combination 74251 encoder / 74374 D flip-flop memory) in parallel in pure TTL logic connected in a linear array. The hardcoded algorithm is the Wolfram encoded 2-state cellular automaton. Posted by Michael O'Brien. Labels: wolfram ttl custom cpu. Wednesday, November 3, 2010.

Multiprocessors, Multicore processors, Multithreading. Monday, November 1, 2010. Custom Multiprocessor Parallel Processing Hardware Experimentation. You can follow progress of the KiloCore prototype on the kilocore.blogspot.com blog. Custom Multiprocessor Parallel Processing Hardware Experimentation:. As we increase the cores past the kilocore range the actual power of the processor is less important - it is the connection topology (Hypercube or rectilinear network) and the parallel problem space that re...
