Raspberry Pi

The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools. (Source: Wikipedia)

We also got hands on the much acclaimed Raspberry-Pi, thanks to OLE Inc in Cambridge, USA. We have tested to see if we could replace our traditional school server with Raspberry-Pi model B. However, Raspberry Pi couldn’t handle the the task when we loaded our digital library E-Pustakalaya on it. Though the page were browsable, the performance was very slow. We replaced Apache with Nginx and optimized Mysql, but still the CPU power was not powerful enough.

cost reduction by embracing latest technology
Upon more investigation, we found more expensive but highly powerful Raspberry-Pi alternatives like Odroid from hardkernel. It comes with 1.7 GHz quad core CPU and 2GB of RAM. We are hopeful that this can replace our single core 1.6 GHz atom processor school server. We can reduce the cost of our future deployment tremendously by substituting MSI server, inverter and battery (for power backup) with Odroid, battery pack and SD card.

Better and Faster OLPC laptops

We are excited about moving to the new XO-4 laptops for upcoming deployments. XO-4 uses power efficient processor based on ARM technology and has expanded storage space. It has the same sturdy design as its predecessors that have earned a reputation for durability and withstood heavy usage by students in rural schools in Nepal.

In mid-February, OLPC sent us an XO-1.75 which is based on same architecture as XO-4 for testing purposes. We were worried to learn that there was no public support of Flash for this architecture since OLE Nepal has invested heavily in Flash. We have over 500 interactive learning modules develop ed on Flash that children in Nepal use to learn various concepts. Not only that, other educational activities in our digital library, E-Pustakalaya, like the British Council’s “Learn English Kids” and “E-Learning for Kids” are also based on Flash.

(We tried other platforms to develop on, but Flash provided us an environment where we could quickly create interactive activities. Later when we learned that Flash was not being supported by many vendors, we were well on our way to build our framework on it and it was too late to switch to other platforms)

Fortunately, with the help of OLPC we managed to run Flash on XO-1.75. This was a major relief for us. Besides that, the performance of new XOs is extremely better compared to the previous versions. Now we are setting up new build system for new XOs which will be deployed this summer.
