These updates feature overhauled windows, new app icons for compatibility with Tahoe, and have been rebuilt. LogUI gets a minor tweak that should improve its window controls in Tahoe.
compression
Raymond Lau’s hugely successful Stuffit dominated Mac compression utilities from introduction in 1987 until Mac OS X in 2001. Also a NuBus card, and most recently AppleArchive.
Why does compressing a 15 GB file within a sparse bundle run more slowly than would be expected from its write performance?
Why data compression is everyday, and how its performance problems can generalise into tasks of similar structure.
Why pay an extra $600 for a 2 TB internal SSD, after all fast external SSDs are cheaper. Maybe you need to check whether disk performance becomes a rate-limiting factor.
Discovering whether using more threads makes a task faster gives insight into where its performance is limited. How to use a VM to investigate this.
Extended attribute editor with much enhanced interface, app inspection tool, compression tool designed for AirDrop use, and a simple extended attribute editor for Spotlight search.
Free that space before macOS has to purge it for you. Using housekeeping, moving Documents and media libraries, but not relocating Home folders.
Explains how Huffman code works, how it’s used for compressed files, and how other techniques including LZ, LZW and LZFSE differ.
Storage has to be reliable, efficient and resilient. However, efficiency and resilience oppose one another. What’s the best solution? New file formats, CRC in the file system, or what?
