FastCompany has a really nice article on Apple’s early history.

The Apple 1 at Retro Computer Adverts.
Retro Computer Adverts has a rather special post to celebrate the 50th anniversary of Apple’s founding; a look at their first – and probably most important product – the Apple 1.
Computer History Museum Recovers Rare UNIX History
The Computer History Museum has a really nice video on how they extracted the data from the University of Utah’s UNIX V4 tape and recovered the first C version of UNIX.
They appear to have uploaded the recovered data to the Internet Archive here.
Tahoe and Window Resizing
Here’s an entirely sensible take on the failures around MacOS Tahoe window resizing. Honestly, OSX worked – there was no need for anyone to prat about with it!
Peak Reddit?
So here’s an odd one: if you put Reddit into Google Trends then there is a distinct peak and then decline.
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…

Adam Savage has a couple of nice videos from the Paramount Film Archives. I especially enjoyed the second of these on the various media formats used over the years.
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.
Language Models are Injective and Hence Invertible
Arxiv has an interesting paper on LLM reversibility and, while the maths is way over my head, the implications of it are definitely interesting.
