MacOS Tahoe’s Terrible Icons

One Foot Tsunami has an entirely reasonable rant about MacOS Tahoe’s terrible Squircle icons. They’re just corporate blanding to the max.

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…

So apparently the firmware for a number of of the old PPC Macs had Easter Eggs embedded within them and, with the right combination of woo, you could get the firmware to spit these Easter Eggs out for you to view.

Another look at Douglas Adams’ office

Another snippet of video and another quick look at Douglas Adams’ office space. Unlike my last post about Adams’ office, I’m having a little trouble narrowing down the source program – though the uploader of the original clip suggests that it may have been recorded around February 1995. If that’s true, then that suggests it was originally shown on a non-BBC channel as I cannot find anything in the BBC genome that references Adams during that period.

Douglas Adams’ Desk and Office in 1996?

This appears to be Douglas Adams’ nicely messy office and his cable spaghetti’d computer setup – complete with what appears to be a fantastic stack of external SCSI drives. Taken from this clip of October 1996’s ‘Break The Science Barrier with Richard Dawkins‘, this footage was likely filmed in the summer of that year.

The Strange Death of the Square Checkbox’d UI

This is a nice little potted history of the use of the square checkbox. It ends noting that Apple appears to have abandoned the use of the square checkbox and chosen to use an icon very similar to a radio button in their new VisionOS – which feels like a big step back in usability.

Space Scapes from Foundation

I must have missed this the first time around but Apple has put up a series of Space Scapes from their rather enjoyable adaptation of Foundation.

Miserablism of the iPhone Variety.

The iPhone 15 Pro in it’s fundamentally miserable set of colours.

Apple Digital Sales

Apple’s European DSA Recipients of Services Report (Archive.org) turned up in my RSS feed and it has some quite shockingly low numbers! Whilst personally I prefer a real book over an e-book, I was very surprised to find that Apple has less than 1 million monthly e-book purchasers across the entire EU! And the tvOS and watchOS user base feels incredibly low as well!

European DSA Recipients of Services Report

Online platforms with 45 million or more average monthly active recipients of the service in the Union, may be designated as very large online platforms (VLOPs). With this framework in mind, the below figures, compiled in accordance with Article 24 (2) of the DSA regarding recipients of the service, are approximated based on information that is readily available to Apple in the normal course of its business:

iOS App Store: 101 million
iPadOS App Store: 23 million
macOS App Store: 6 million
tvOS App Store: 1 million
watchOS App Store: under 1 million
Apple Books: under 1 million
Podcasts paid subscriptions: under 1 million

Leaking Pipes with Swift and External Executables

Observed with MacOS 12.4/Xcode 13.4.1/Swift 5

There are quite a lot of tutorials out there covering the basics of running external executables from within Swift and, with very little effort, it’s quite easy to throw together something like this…

import Foundation

let wrappedUname = Process()
wrappedUname.executableURL = URL(fileURLWithPath: "/usr/bin/uname")
wrappedUname.arguments = ["-v"]
let unameOutputPipe = Pipe()
let unameErrorPipe = Pipe()
wrappedUname.standardOutput = unameOutputPipe
wrappedUname.standardError = unameErrorPipe
do{
    try wrappedUname.run()
} catch {
    print("Unexpected error: \(error).")
}
wrappedUname.waitUntilExit()
let unameOutput = String(decoding: unameOutputPipe.fileHandleForReading.readDataToEndOfFile(), as: UTF8.self)
let unameError = String(decoding: unameOutputPipe.fileHandleForReading.readDataToEndOfFile(), as: UTF8.self)
print("Output: " + unameOutput)
print("Error: " + unameError)
