  "description_en": "The Hack Different community's knowledge base on Apple hardware, firmware and operating-system internals, set up and largely maintained by Rick Mark, which pairs a long categorized link list with original pages and machine-readable YAML data. The README groups references from Mach-O, the dyld shared cache, img4 and boot policy to the Secure Enclave, basebands, USB and Lightning, wireless protocols and diagnostic formats, while the data folder holds 56 topic files plus per-device, certificate and firmware-key records on devices, chips, IPSW builds, Mach-O constants, NVRAM, boot arguments, lockdownd services and entitlements. Rake tasks regenerate parts of the data from Apple's update feeds, The iPhone Wiki and local Apple binaries, and the data is also published as apple-data packages for Ruby, Python and Node.js.",
