Edinburgh buried in a dark rain cloud today, with a cold wind from North Sea, which made it all the more surprising that I really enjoyed my run today! #runthemonth runthemonthme.prostatecanceruk.org/fundraising/...

Seventy miles down, 30 to go #runthemonth. We're on track to reach 100 miles by end of January though 30 miles in the next 10 days seems daunting. runthemonthme.prostatecanceruk.org/fundraising/...

Tough 12km around Newbattle Abbey this morning for #runthemonth. Not sure whether the mud or the ice was worse. At least there weren't too many climbs and descents ... Oh, wait a minute. runthemonthme.prostatecanceruk.org/fundraising/...

Lunchtime run around Arthur's Seat for #prostatecanceruk #runthemonth, though when I say "around", there is still a fair amount of climbing involved. Good to have the company of some work colleagues from @epcc.bsky.social. runthemonthme.prostatecanceruk.org/fundraising/...

If you need some more festive decorations for Christmas, why not power up your #JupiterAce/ #Minstrel4th and run AceSnow (inspired by Xsnow which adorned my Unix workstation in December for much of the 1990s). #retrogaming github.com/markgbeckett...

For reasons I have not got to bottom of, Tree Forth's support for Timex Sinclair 2040 printer is broken (even though ZX Printer support seems correct). I have swapped out Tree #Forth kernel for Sinclair BASIC version and now works as expected. Testing here on #Minstrel4th. github.com/markgbeckett...

With help of @robertprice.bsky.social , I've connected my Timex Sinclair 2040 printer to my @tynemouthsoftware.co.uk #Minstrel4th. ZX Printer was well-supported by #JupiterAce with lots of software, which I'll be exploring. www.robertprice.co.uk/robblog/usin... www.jupiter-ace.co.uk/sw_zxprinter...
