Five Hundred and Seven Mechanical Movements

Five Hundred and Seven Mechanical Movements is a lovely online compendium of Henry T. Brown’s classic technical reference Five Hundred and Seven Mechanical Movements. The classic illustrations (taken from a 1906 edition of the text) are just wonderful – as are the modern animated sequences that show the motions in question. My current favourite is No. 92 – better known to most as the mechanism used to drive a steam locomotive!

Retrieving the Time Machine Estimated Full Backup Size for MacOS Tahoe

Well, it’s been a little while since I last looked at sizing Time Machine backups on MacOS and, with MacOS 26 (‘Tahoe’), the magic incantation needed to pull that information out has changed.

Open up a terminal and enter the following…

log show --predicate 'subsystem == "com.apple.TimeMachine"' --info | grep "will be in backup of all sources" 

…and this will print out a number of records from previous Time Machine sessions thus…

New Old Stock IBM OS/2 Warp 3.0

Abort Retry Fail has a really nice post on opening and installing a new old stock Red Spine release of OS/2 Warp 3.0.

Now, while I’ve played around with OS/2 Warp 4.0 and 4.52 as part of Period Sites in Period Browsers, Warp 3.0 is not one I’ve yet reached.

And how uncanny it looks! Familiar but alien. Windows 3.1 but not. I should really get an instance of this up and running just so I can really feel – rather than just see – the differences between how I expect it to work and how it does work…

Anyway, I strongly suggest going and having a read of the article and a look at the pretty pictures.

Remembrance Toppers and Other Remembrance Knitwear in Malton

TopperBlog returns with a set of Remembrance Toppers and other knitwear. I’m not posting any images from the memorial itself as I’m sure there are far better pictures from the service on Sunday already online.

There’s been a lot of work put into these commemorations and, sadly, I’m not entirely sure I’ve managed to find them all.

The Marketplace Post Box

‘Lest We Forget’ by the Post Office. The boots and the helmet had really stood up to the effects of the weather.

York Minster from Lop Lane

Whilst poking around on Getty.edu’s art search site I managed to stumble on this fascinating but sadly poor photograph of what is now the junction between Museum Street, St Leonard’s Place, Duncombe Place, and Blake Street. The photos current location can be seen on the StreetView below.
