| Fixed in iOS 13.4 with CVE-2020-9768 | |
| AppleJPEGDriverUserClient : mach port use-after-free/type-confusion via race condition | |
| AppleJPEGDriverUserClient external methods can be used synchronously or asynchronously, when used asynchronously, | |
| it brings the registered mach port (via registerNotificationPort()) and put it inside jpegRequest data structure, | |
| and no reference count was taken for this operation. since registerNotificationPort() is not gated, it is | |
| possible to release the port (if the port got substituted) during the processing of jpeg request and end up | |
| with dangling pointer passed to _mach_msg_send_from_kernel_proper(). |

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

Just a quickie test in Python 3 (using Requests) to see if Google Cloud Vision can be used to effectively OCR a scanned data table and preserve its structure, in the way that products such as ABBYY FineReader can OCR an image and provide Excel-ready output.
The short answer: No. While Cloud Vision provides bounding polygon coordinates in its output, it doesn't provide it at the word or region level, which would be needed to then calculate the data delimiters.
On the other hand, the OCR quality is pretty good, if you just need to identify text anywhere in an image, without regards to its physical coordinates. I've included two examples:
