Compiler Error
1 - March of 2020 saw the release of many new updates, including the Powerbeats: a low cost wired version of the Powerbeats Pro and an upgrade to the Powerbeats 3.
2 - The Mac mini was updated not once, but three times in 2020, offering lower-priced storage options back in March, a limited release Developer Transition Kit in June, followed by the much-anticipated M1 transition in November.
3 - Also updated twice in 2020, the March update of the MacBook Air did away with the rose gold color option, but replaced the keyboard, introducing TouchID without a TouchBar for the first time.
4 - In true Mac Pro fashion, Apple kept it’s promise and released Apple Fitness+ before the end of 2020, completing Apple’s Apple One offering, announced back in September.

Compiler Error
1 - Lyft’s CEO sued Uber for allegedly and on multiple occasions sending escorts to his private home, as a supposed retaliation and intimidation tactic against Lyft’s then-expansion into New York City, which was settled for $2M.
2 - An antitrust lawsuit was filed against Uber by a passenger claiming collusion with drivers to raise prices, which later got dramatic when Uber privately investigated said passenger using “fraudulent and arguably criminal conduct”.
3 - A former Uber driver filed a lawsuit against Uber regarding its star rating system, which the plaintiff claims disproportionately leads to the firing of people who are not white or who speak with accents.
4 - As recently as August, California's labor commissioner is once again suing Uber and Lyft, claiming the companies are stealing wages from drivers by "willfully misclassifying" them as contractors instead of employees.

Compiler Error
1 - USB4 consolidates various USB transfer modes introduced over the years by basing itself on the Thunderbolt 3 protocol, though host-support for tunneling existing Thunderbolt devices over a USB4 port is optional.
2 - Much like Thunderbolt 3, demonstration versions of Light Peak used a modified USB port, being run from a prototype Mac Pro logic board, transmitting data over a 30-meter optical-fiber cable.
3 - Thunderbolt 1, 2, and 3 can support up to 6 daisy chained devices, however devices that can make more than one downstream Thunderbolt port available will require a Thunderbolt 4 compatible computer.
4 - The copper variation of Light Peak was co-developed by Apple and Intel, with Apple trademarking the term Thunderbolt, though the trademark was later transferred to Intel.

Compiler Error
Tagged pointers encode their entire object into the non-addressing bits of a pointer, ultimately allowing faster allocations for specific hard-coded classes known by the runtime.
NSZone’s primary purpose was to allow objects to be allocated within the same memory page, so swap would be fast, and those objects could be free’d in one go.
NSProxy is a non-NSObject base class that allows for message dispatch to be easily redirected to another object, but does not have an initializer implemented for subclasses to fall back on.
__NSAtom is a special class that is ultimately the boolean-opposite to nil: any message you send it will always return an __NSAtom, which is very intentionally equal to 1.

Compiler Error
Unlike many languages, Smalltalk has no if statement, let alone other control structures. Control flow is instead implemented as methods sent to objects.
Like Objective-C, Smalltalk makes use of argument labels on each of a methods arguments, but does not wrap every method call in square brackets.
Only six "keywords" are reserved in Smalltalk: true, false, nil, self, super, and thisContext, which are called pseudo-variables in the language.
Like many languages in the 80s, Smalltalk uses the dot character to access properties, the semicolon to delineate statements, and curly brackets to denote blocks.

Compiler Error
1 - Hoping to improve Javascript, Objective-J was invented as a way of bringing Objective-C’s class and message sending syntax and more over to web development, but without the *’s.
2 - Objective-C++ is a variant of Objective-C that adds the same extensions to C++ as it does to C, effectively duplicating the implementations of classes, exception handling, and closures.
3 - Objective-C# is another variant of Objective-C started in 2009 after the success of the iPhone hoping to bring dynamic dispatch to C#, but was not actively maintained.
4 - Inspired by an off-hand remark, Objective-Rust is a toy language recently developed that adds some Objective-C syntax to Rust, for better interoperability between the two languages.

Compiler Error
Neuralsort makes use of a convolutional neural network to sort at O(2n) speeds on average, though the worst case can take quadratic time.
Spaghetti Sort is capable of sorting its contents at O(n) speeds even in the worst of cases, but requires a quadratic amount of memory in the process.
Bogosort uses the power of random shuffling to achieve a computational complexity of O(n) in the best of cases, but is unfortunately not stable in the process.
Named after Tim, Timsort is used in Swift 5 to perform sorting needs in Arrays, which is especially tuned to reversing the order of an already sorted collection.

Compiler Error
The UTF-32 view provides access to each character as a 4-byte UInt32, representing the complete range of all 4 billion unicode code points, but in their original, possibly decomposed, forms.
The UTF-8 view optimizes for memory at a disadvantage to manipulation speed, since each unicode character may be represented by one or more bytes, making length calculations costly, but necessary for many C APIs.
Easily accessibly by treating a string like a collection, the default view represents normalized characters as they would be displayed on screen, even if they were originally decomposed.
The UTF-16 view is optimal when interacting with unicode libraries such as Objective-C’s NSString since it vends UInt16 code-points, as is standard in many programing models.
