Nonprofit Worldreader gives Kindles to students in sub-Saharan Africa (and is working on a reading app for mobile phones). The organization just published the results of iREAD, its year-long pilot program in Ghana, and many of the findings are promising: Primary school students with access to e-readers showed significant improvement in reading skills and in time spent reading, and the program is cost-effective. The theft rate was “near-zero,” but nearly half the e-readers broke.
USAID funded the Worldreader Ghana study and independent firm ILC Africa did the research. iREAD “involved the wireless distribution of over 32,000 local and international digital books using Kindle e-readers to 350 students and teachers at six pilot schools in Ghana’s Eastern Region between November 2010 and September 2011.”
The full results are here (PDF). Some findings:
- Kids learned to use e-readers quickly even though 43 percent of them had never used a computer before. Also…

- all the machines have been formatted and Arch base system installed according to the guide
- the machines are connected via a TCP/IP network with the ip addresses and hostnames noted down as they will be required in later steps.
- each machine has a common login account (in this case baloo)
- all machines are using the same processor architecture i686 or x86_64
Its always a good idea to get the latest and up-to date Arch system so a quick:pacman -Syu

The aim is to design and model an 8086 based computer and add several interfaced peripherals to it.The system has been designed to meet the following requirements :
Total 32Kx16 SRAM
Total 64Kx16 EPROM
I/O Ports Parallel
I/O Ports analog-digital
a block diagram of the system showing the functional units relationships to each other .The desccriptions that follow are based on this model and willthus be referrd to as per the module it currntly appears in And below is a preliminary sketch of the completed system.CAVEAT:This is how the completed system will look like however pin outs may change regarding the availiability of ICs.
I wıll be going through the different modules step-by-step in the upcoming posts .
