If these drives were initialized in Windows, be sure that they have sharing, permissions, and security all set up first. SMB is Windows land, Linux is only a guest.

Forth. The only 'frameworks' I use are those that I wrote myself. I don't have to recite chants to doctrinal gods. I just create.

Re: Raspberry Pi as the successor of BBC Micro

Remember, the aim is to teach. And part of teaching is using a modern machine. Why would you teach someone to use something like a BBC micro, when there is no longer such a thing as a BBC Micro? What they learn on it would not be relevant. I'm not talking about languages, but the instant on approac...

Re: Pi 2... Is it a bit fragile?

I've seen a few add-on cards that are mostly protoyping real estate with a few surface mounted chips (eg EEPROM or processor). Maybe a Pi with only the SoC and bare minimum of support could be produced, especially if it required no redesign, only the non-installation of some components.

Re: Raspberry Pi as the successor of BBC Micro

Great for us middle aged engineers, but not like the Micros of the 80s where we learned to program. To make the Pi a successor of an 80s micro, you need to power on and be programming within one second, without first understanding concepts like software dependance and linked libraries. The idea of ...

Re: Any chance of update for BOINC.

It's in the works. Since this update involves Debian maintainers, Raspbian maintainers, and perhaps even dependencies like WxWidgets, be patient. Stanford has written the code, it's just a matter of it percolating down to Pi-dom :)

Re: POE support on Rpi 3

1 or 2 buttons and 1 or 2 LEDs connected to GPIO. This would allow the Pi to do something right out of the box, thereby capturing the attention of the Internet generation.

Re: BBC Micro Bit

I don't think they (ARM & BBC) see the Micro Bit as a pi-killer, rather as a complementary, entry-level device (why sell just one ARM, when two or three will do nicely). What I'm sad about is that 11 year olds don't need Python or C++ (!!), what they really should be learning is Forth.

Re: The Future of the Pi A series

One of the potential uses of the A series is as a "micro blade" in clusters. FWIW in a B+ running 1 BOINC task, I get 70% CPU usage and 20% RAM usage (for just that task). This pretty much soaks up whatever's left by the GUI at rest. So, dual core may be useful, but more RAM is going to be a must af...

My 2c from across the pond. The BBC may have a great rep in Britain, but apart from WWII films using the "This is the BBC" booming radio voice, and "Spitting Image" during the 80's, it's not so well known over here. The pi is.
