(is there a way of detecting 32/64 bits so the makefile could be 'universal'?).
From the shell

Code: Select all

getconf LONG_BIT
returns 32 or 64. From a Makefile, I do not know how.

Re: Using GitHub - introduction & tutorial

That's really nice! I've never used the GUI, only the command line tools. It seems a little strange to have to use a pull request then local sync to get your local files sorted out, but if it works … It's also likely much less of a faff than with the command line tools, though. A useful feature that...

Re: Request for help in organising/releasing source code

The 64-bit Linux edition has been downloadable from my website for a month or so Yes, I just noticed that. It installs and runs beautifully. Thank you! The reason it's not an 'official' release is the obvious one: unless and until there's an x86_64 assembler, it doesn't qualify as 'proper' BBC BASI...

Re: Request for help in organising/releasing source code

Richard - one really nice thing about having the source code here in front of me is that it includes a runnable x86_64 version. The previous releases required 32-bit compatibility libraries to run on 64-bit Ubuntu, and these just never worked correctly for me. At least on the Linux side, your code o...

Re: Pi-based Co-Pro on the cheap - 100MHz 6502 for £10? (now 274MHz)

The only thing here is that I'm not sure how linux is going to take to just being switched off without shutting down. Badly. The usual way to do this is to have a read-only root filesystem and have the user filesystem in RAM. You might be able to do this on a Zero, but I'd be more worried about the...

PostScript will only do bold for you if you've downloaded the bold variant to the printer and make the switch to that font explicitly. There's no "make this bold" command in PostScript as it ships.

Can confirm the both Capslock issue and the two-symbols-on-GET on local Ubuntu x86_64 (Gnome3?) and local Raspbian (ARM, LXDE). The Capslock issue doesn't happen on VNC to the Raspberry Pi, but the two-symbols thing does. So I don't think it has much to do with window manager. Still seeing the issue...

Unfortunately my 3D printer seems broken. That's pretty much natural state for most 3D printers. I work with them for my day job, and keeping them running is endless hassle.
