Re: Connect To Eduroam

Dear mshah, Here's a guide to using Eduroam, based on my experience connecting successfully at two universities. It has no official standing. But it may be helpful. N.B. It does involve leaving a network username and password in a plain-text file on the SD card! So depending on the use situation, it...

Re: Emulate Raspberry Pi under Android

Many thanks all, for the swift and helpful pointers. Heater asked about why. I'm exploring ways to make our 4273pi materials (http://4273pi.org) more conveniently usable on a range of platforms. If Android could be made to boot the 4273pi SD card image within an app, that could be one mechanism to p...

Emulate Raspberry Pi under Android

Has anyone used an Android app to run Raspbian under emulation on Android? I would like to boot a Raspberry Pi SD card image within an Android app. Ideally it will be an "official" solution, e.g. App available from Google Play and no rooting required. Any pointers or shared experiences will be welco...

Dear gsgs, 4273pi is distributed as an SD/microSD card image for the Raspberry Pi. The teaching material is also available separately, as a zipfile (4273pi_course_material.zip). The zipfile could be useful on other systems too. We consider the Raspberry Pi to have various advantages for bioinformati...
