Re: STICKY: X86 Debian Stretch with RPi Desktop

This is great. Brought a barely working Aspire One with a tiny HD back to life. Will be trying out the GPIO expander in the next couple of days. What a nice idea. Just wish it was easier to get the Raspberry Pi zero's in Canada. The options seem to be by a starter kit or go on a backorder waiting li...

Re: Fixing a missing taskbar on the x86 image (obsolete)

In my case the problem went the sound section and the CPU section did not seem to make a difference. Problem seemed to resolve after removing the battery section. This occurred on an old very old Aspire one. No such problem on a newer aspire one. Note that I downloaded the image just two days ago. C...

Re: /etc/inittab no longer present in Raspbian Jessie?

Thanks for the suggestion, I checked the config.txt file and enable_uart=1 was already in the file, but there is still no /dev/ttyAMA0 file when I boot. I'm, trying to write from a python script to the serial port. On my Pi Zero, the cmdline.txt doesn't refer to ttyAMA0, but serial0 which is linked...

Re: Meet Raspberry Pi Zero: the $5 computer

$5 US or perhaps $10 Canadian sounds like an amazing price (can't see a price on http://canada.newark.com/ but $14 here http://www.bc-robotics.com/shop/raspberry-pi-zero/). So can one move the memory card between different Pi models? I guess I'm thinking it would be easiest to load packages on a Pi ...

I see this quite differently. I would emphasize that the Pi is a very small inexpensive computer and not just a faster MCU.

I have toughtplenty of people that have zero background in programming BBC BASIC in under 3 days. Now if they have zero background in math (like many 5 and 6 year old kids) it will take a couple of weeks to teach. Though I do not think that this would be a problem with 99% of teachers.

You disagree with my choice of words. That's OK; I'm not perfect. Do you disagree with my conclusion? It may be different in the UK but I suspect most teachers here have next to zero background in programming. The BBC BASIC manual I looked at is over 400 pages. I don`t think someone is going to lea...

Nice to know that you have the ability to know what the future holds in 16 to 20 years, when the kids we teach today will be out of university and looking for jobs. Besides they will have had plenty of time to learn many other languages before that. Kids come to University today with no programming...

And it gave you a spring board into other more grown up languages. BASIC doesn't seem to have done you any harm. I doubt you had to undergo a course of counselling after learning BASIC.
