Re: Where do I find Scratch projects compatible with the RPi

Question for you - when you ask for floor & ceiling I imagine you mean as in floor() & ceiling() per http://en.wikipedia.org/wiki/Floor_and_ceiling_functions - yes? Yes! They are the only new math-functions in Scratch 2 compared to Scratch 1.4. When you ask for cloning, what do you mean? Take a spr...

Re: Where do I find Scratch projects compatible with the RPi

I discovered that a file can be opened in Scratch 2 Offline Editor (that cannot run on Raspberry Pi, due to lack of AIR) even if the MD5-codes and extensions for png-files are incorrect (which is an advantage). This bash command-line converts an sb2-file with vector-images to an sb2-file with bitmap...

Re: How to copy from a browser into e.g. a terminal?

How to copy from a browser into e.g. a terminal?

I wanted to copy some bash code from a forum into the terminal when I run X in the latest Rasbian from Raspberry Pi. I tested all three browsers and even installed links and run that in another terminal tab, but I was either not able to select text using the mouse or when I used Ctrl+C or Copy from ...

Benchmarks

I've written a benchmarking program that runs on Raspberry Pi. I tested the new Rasbian image and it runs almost double as fast as Scratch 1.4 on my PC from 2007 with Ubuntu 10.04 LTS, but Scratch 2 runs about thousand times faster on the same machine. You can download it using the command-line: pro...

It's difficult now because you have to rewrite the progra...

Re: How small is the smallest bare metal system with video?

This sounds promising. It would be better for me if it supported composite video.

I already have some small SD-ca...

How small is the smallest bare metal system with composite or HDMI video? Would it fit on a 64 MB SD-card (the smallest I have)? I think it would be an advantage if such a small system existed because then people could use cheap small SD-cards to experiment easily with.

I did test the various fonts and this is an alternative to changing resolution, but all fonts that could give 40 chars per line are too high to give 25 lines.

Width 40 characters per line in Linux console w/o X?

Is it possible to set the width to 40 characters per line in the Linux console (i.e. without X)? It would make many console applications that don't need X easier to read on a composite video monitor. 50 characters per line would probably also work. I know I can start DOSBox (w/o X) and then GWBASIC ...

Re: Header for data pins on micro USB connector

I think a Raspberry Pi with only a header would be a great idea also for schools. Then you would have all connectors on another board connected to the header on the Pi. The advantage of this is that the processor board will be cheaper, since the connectors for HDMI, composite video, USB, stereo soun...
