• Feedback: Academia and Industry — Do either of you have any insights as to how the software development community would view someone with a math PhD, but no industry coding experience as a job applicant? Any advice would be appreciated.
• Feedback: Absurd Abstractions — FYI about wanting `interface` in Python: they are called abstract base classes. Check out the standard library module, abc for that and collections.abc some useful predefined container interfaces.
• Feedback: Breaking Changes — I developed  a niche Python package that has some user following in the network security realm.  I’m at a crossroads though as a change I want to make will subtly break scripts that worked in previous/current versions.  The end result of my pending change  is good for the project but I fear I’ll ruin the workflow of my users.  Other than my github page I don’t know how to query/inform my users of this pending change.  What should I do?

• Altruism Still Fuels the Web. Businesses Love to Exploit It | WIRED — The original well-meaning, geeky architects of the web believed that there was an abundance of altruism in human nature—and they were more correct on this count, it turns out, than many esteemed social philosophers were. But they were too optimistic in overlooking the possibility that corporations would exploit and colonize this new realm. If only we had all seen it coming.
• The Crystal Programming Language — Crystal is statically type checked, so any type errors will be caught early by the compiler rather than fail on runtime. Moreover, and to keep the language clean, Crystal has built-in type inference, so most type annotations are unneeded.
• The Imposter's Handbook by Rob Conery — You've had to learn on the job. New languages, new frameworks, new ways of doing things - a constant struggle just to stay current in the industry. This left no time to learn the foundational concepts and skills that come with a degree in Computer Science.

Plus why everyone's talking about the sensitivity conjecture, speedy TLS with rust, and more!

• Feedback: Which Language To Use And Why? — There are so many languages out there, and I just don’t understand when or why you would want to use a language over another.
• Mathematician Solves Computer Science Conjecture in Two Pages | Quanta Magazine — This “sensitivity” conjecture has stumped many of the most prominent computer scientists over the years, yet the new proof is so simple that one researcher summed it up in a single tweet.
• ELI5: The Sensitivity Conjecture has been solved. What is it about? — Think of it like a Buzzfeed quiz. You answer a bunch of multiple-choice input questions about seemingly random topics ('What's your favourite breakfast cereal?', 'What's your favourite classic movie?', 'What did you want to be when you grew up?', and so on), and you get a response back at the end: usually which Hogwarts house you belong in.
• Sensitivity Conjecture resolved — Paul Erdös famously spoke of a book, maintained by God, in which was written the simplest, most beautiful proof of each theorem. The highest compliment Erdös could give a proof was that it “came straight from the book.” In this case, I find it hard to imagine that even God knows how to prove the Sensitivity Conjecture in any simpler way than this.

• GitHub starts blocking developers in countries facing US trade sanctions — There's a debate over free speech taking place after Microsoft-owned GitHub "restricted" the account of a developer based in the Crimea region of Ukraine, who used the service to host his website and gaming software.

• 1995parham/github-do-not-ban-us: Github do not ban us from open source world — GitHub restricted our access to private repositories suddenly, but at the very least we wanted GitHub to warn us before limiting our access.
• A Rust-based TLS library outperformed OpenSSL in almost every category | ZDNet — The findings are the result of a recent four-part series of benchmarks carried out by Joseph Birr-Pixton, the developer behind the Rustls library.
• TLS performance: rustls versus OpenSSL — A TLS library will represent separate sessions in memory while they are in use. How much memory these sessions use will dictate how many sessions can be concurrently terminated on a given server.
• Nat Friedman on Twitter — Users with restricted private repos can also choose to make them public. Our understanding of the law does not give us the option to give anyone advance notice of restrictions.

Plus Mike gets real about the Windows Subsystem for Linux, and our take on the new MacBook keyboard leak.

• Apple is reportedly giving up on its controversial MacBook keyboard - The Verge — Apple is planning to ditch the controversial butterfly keyboard used in its MacBooks since 2015, according to a new report from analyst Ming-Chi Kuo. 9to5Mac notes that Apple will reportedly move to a new scissor-switch design, which will use glass fiber to reinforce its keys. According to Kuo’s report, the first laptop to get the new keyboard will be a new MacBook Air model due out this year, followed by a new MacBook Pro in 2020.
• Objective-C - History - Wikipedia — After acquiring NeXT in 1996, Apple Computer used OpenStep in its then-new operating system, Mac OS X. This included Objective-C, NeXT's Objective-C-based developer tool, Project Builder, and its interface design tool, Interface Builder, both now merged into one application, Xcode. Most of Apple's current Cocoa API is based on OpenStep interface objects and is the most significant Objective-C environment being used for active development.
• A Short History of Objective-C — While most programmers discovered Objective-C only during the iPhone app revolution, Objective-C has been around for over 30 years. Objective-C has been the foundation of Apple’s desktop operating system, Mac OS X, since its debut in 2001, and was also the basis for NEXTSTEP — OS X’s immediate ancestor — created by Steve Jobs’ NeXT Computer Inc. However, Objective-C was created neither by Apple nor NeXT. Its origin was a small Connecticut startup in the early 1980s called Stepstone.
• GNUstep — GNUstep is a mature Framework, suited both for advanced GUI desktop applications as well as server applications. The framework closely follows Apple's Cocoa (formerly NeXT's OpenStep) APIs but is portable to a variety of platforms and architectures.
• GNUstep: Fun with Objective-C — Objective-C is a language based upon C, with a few additions that make it a complete, object-oriented language. Why do I think Objective-C is fun? Precisely because of this emphasis on simplicity

• Installing and Using GNUstep and Objective-C on Linux - Techotopia — The basics of Objective-C are supported by the GNU compiler collection. In order to utilize the full power of Objective-C together with the Cocoa /openStep environments on Linux, and to work with many of the examples covered in this book, it is necessary to install gcc, the gcc Objective-C support package and the GNUstep environment.
• Objective-C Compiler and Runtime FAQ - GNUstepWiki — The history of Objective-C in GCC is somewhat complicated. Originally, NeXT was forced to release the original Objective-C front end in order to comply with the GPL. This code was not quite compatible with the GNU runtime and so it was modified. NeXT did not adopt these modifications and so each release of GCC by NeXT, and then Apple, contained changes that needed back-porting to the main branch of GCC. For a long time, GCC was the only compiler that worked with GNUstep. Unfortunately, the GCC team has not invested much effort in Objective-C in the last few years and it currently lags behind Apple's version by a significant amount.

Plus feedback with a FOSS dilemma and an update on our 7 languages challenge.

• Feedback: Lance’s FOSS Quandary — I was working on an open source project for school that we (4 members) submitted. Myself and another did 98% of the work the others contributed to the documentation (outside of the codebase). Class is over now for many months and nobody has touched the code but one other member and I wish to keep it going.
• Feedback: Developer, have money for a new Mac Pro? Buy these instead. — The recently unveiled Mac Pro is no doubt a gorgeous machine, engineered for a very particular group of people. While it will likely be a great machine for those who live and breathe within Finalcut and work with ProRes files, it’s overkill for a good developer machine.

• Mike's Blog: Converting to SwiftUI Steps[0] — SwiftUI is the next paradigm in iOS and macOS user interface development. However, if you’re like me you already have Xcode projects that are using the now legacy storyboard technology. Luckily, it possible to update your existing projects to use SwiftUI and the process is very straightforward.
• Mike's Blog: Converting to SwiftUI Steps[1] — Continuing my journey into SwiftUI, I am taking a look at re-using existing UIViews and UIViewControllers in SwiftUI. The primary advantage here is not having to rewrite your existing code from scratch, however, it’s probably best to create any new views in SwiftUI directly rather than UIView.
• SwiftUI for React Native Developers — Developers with React Native experience may notice some similarities to the philosophies Apple has imbued into their new UI framework. Utilizing structs as immutable value types for view modeling, a declarative syntax, and with their new async event library Combine, a reactive architecture.
• SwiftUI - Apple Developer — SwiftUI is an innovative, exceptionally simple way to build user interfaces across all Apple platforms with the power of Swift.
