Links:

• Feedback: Getting started on .NET? — My question is what is the easiest route to get started in .net development? When I looked online there are several different languages that can be used from C# ,F#, ASP.NEt among others. In your personal experience what is the easiest way to get started on this path?
• Feedback: Questioning Rust — [...] The primary issue here is that most of the work to prove that safety (beyond "trust me" blocks) is pushed onto the developer instead of having the compiler insert protections surmised from uses of the data structures outlined in the source code.  After all, it can only prove what it is shown, not what it assumes.
• Feedback on Mike and Macros — I'd also love to hear more about what you dislike about macros. Personally, I view Rust's macro system as one of its biggest selling points. I've written more than a few macros myself and, every time, they've simplified my code in ways I couldn't have managed without them. Perhaps more importantly, I've also noticed that many of my favorite crates make heavy use of macros—and doing so lets them expose a much more ergonomic API.

Plus your feedback, Mike’s next language challenge, and a functional ruby pick.

• Feedback: Clojure, Racket, and Extempore — Thinking about the problem could take the form of leveraging the REPL to work out code to solve a problem or you could spend some time away from your computer screen (or in “Hammock Time”) working out problems.  If I have learned anything from Clojure’s creator, “Rich Hickey” its “Programming is not about not about typing, it’s about thinking”.
• Knuth's Sensitivity Conjecture One-Pager
• Law Of Leaky Abstractions — All non-trivial abstractions, to some degree, are leaky.
• The Law of Leaky Abstractions – Joel on Software — This is what I call a leaky abstraction. TCP attempts to provide a complete abstraction of an underlying unreliable network, but sometimes, the network leaks through the abstraction and you feel the things that the abstraction can’t quite protect you from.
• Forget about Leaky Abstractions — Even if an abstraction is leaky it can still be useful. Sometimes you cannot escape it (uniform memory) and sometimes the workaround is costly to implement (TCP, SQL). So you accept the technical debt for now. Hope the debt does not kill the project. Maybe there will come a time where it is worthwhile to pay off the debt.
• All Abstractions Are Failed Abstractions — It's our job as modern programmers not to abandon abstractions due to these deficiencies, but to embrace the useful elements of them, to adapt the working parts and construct ever so slightly less leaky and broken abstractions over time.
• Appropriate Levels of Abstraction — Instead of aspiring to higher levels of abstraction, we should instead seek to work at the appropriate level of abstraction for the problem at hand. The appropriate level is sometimes very high and sometimes very low. It varies for different situations even in the same software project. Just as other engineering disciplines require different tools for different situations, software development also requires tools and languages that support our work at multiple levels of abstraction.
• Choosing The Proper Level of Abstraction — In software development, choosing the right abstraction can be tricky. If you make it too simple, it won’t let you create a model to satisfy even the immediate requirements. If you make it restricted to the urgent needs, you might have to change it almost immediately to implement the next iteration of the model. However, if you make your abstraction too generic and all-encompassing, modeling solutions might get so complicated that you’ll go out of business before you are finished.
• 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.
• affect: Algebraic effects for Ruby — Affect is a tiny Ruby gem providing a way to isolate and handle side-effects in functional programs. Affect implements algebraic effects in Ruby, but can also be used to implement patterns that are orthogonal to object-oriented programming, such as inversion of control and dependency injection.
• Algebraic Effects for the Rest of Us — Imagine that you’re writing code with goto, and somebody shows you if and for statements. Or maybe you’re deep in the callback hell, and somebody shows you async / await. Pretty cool, huh? If you’re the kind of person who likes to learn about programming ideas several years before they hit the mainstream, it might be a good time to get curious about algebraic effects. Don’t feel like you have to though. It is a bit like thinking about async / await in 1999.

Plus your feedback, combining ruby and rust, and the latest scandal with JEDI.

Links:

• Emacs Feedback from DJ — Another point for the show is a soft intro to functional programming. Wes mentioned Emacs because of the packages supporting Clojure development when he started with that. Elisp seems to be fairly intuitive and well documented, as a little functional language its own right (correct me if I'm wrong)--this makes for a soft intro to FP. Most of my coding has been in the space of embedded systems and low-level languages--not much functional programming to be had. This show has gotten me curious about FP, which is quite old in concept, and getting implemented nicely in modern languages. For me, I still rely heavily on special Vim keys that are not mapped in evil-mode, which causes some paper cuts. However, elisp makes it easy to customize the desired UI functionality with very short programs/elisp statements in a config file. It's quite a refreshing exercise for someone like me.

• 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.

• 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.

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 Wes asks 'Why Not Kotlin' and breaks down where it fits in his toolbox.

Links:

• Kotlin overview — Kotlin is an open-source, statically-typed programming language that supports both object-oriented and functional programming. Kotlin provides similar syntax and concepts from other languages, including C#, Java, and Scala, among many others. Kotlin does not aim to be unique—instead, it draws inspiration from decades of language development. It exists in variants that target the JVM (Kotlin/JVM), JavaScript (Kotlin/JS), and native code (Kotlin/Native).
• Kotlin/Native — Kotlin/Native is a technology for compiling Kotlin code to native binaries, which can run without a virtual machine. It is an LLVM based backend for the Kotlin compiler and native implementation of the Kotlin standard library.
• Kotlin for JavaScript — Kotlin provides the ability to target JavaScript. It does so by transpiling Kotlin to JavaScript. The current implementation targets ECMAScript 5.1 but there are plans to eventually target ECMAScript 2015 as well.
• My favorite examples of functional programming in Kotlin — One of the great things about Kotlin is that it supports functional programming. Let’s see and discuss some simple but expressive functions written in Kotlin.
• Arrow: Functional companion to Kotlin's Standard Library — Arrow aims to provide a lingua franca of interfaces and abstractions across Kotlin libraries. For this, it includes the most popular data types, type classes and abstractions such as Option, Try, Either, IO, Functor, Applicative, Monad to empower users to write pure FP apps and libraries built atop higher order abstractions.

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.

It is said that Clojure is a "functional" programming language; there's also talk of "data-driven" programming. What are these things? Are they any good? Why are they good? In this talk, Rafal attempts to distill the particular blend of functional and data-driven programming that makes up "idiomatic Clojure", clarify what it looks like in practise (with real-world examples), and reflect on how Clojure's conventions came to be and how they continue to evolve.

• Goodbye Joe — One of the amazing things Joe mentioned in his texts that was out of the ordinary compared to everything I had read before is that developers would make mistakes and we could not prevent them all. Instead, we had to be able to cope with them. He did not just tell you about a language, he launched you on a trail that taught you how to write entire systems
• Goodbye Joe in r/programming — About two weeks ago I came across Armstrong's blog for the first time and poked around at a few posts. I noticed he had recently (in the past year was my impression) discovered TiddlyWiki and rewritten his blog in it. His post talking about his eureka moment with TiddlyWiki had the feel of a very young, excited writer, so I was very surprised to later discover his age. I didn't know about him for very long, but the character described in this post really shined through.

And as if to prove a point, the update works only in Edge and Chrome. Firefox, Safari, and even Opera are locked out.
• The 737Max and Why Software Engineers Might Want to Pay Attention — What is different here is: the MCAS commands the trim in this condition without notifying the pilots AND to override the input, the pilots must deactivate the system via a switch on a console, NOT by retrimming the aircraft via the yoke, which is a more common way to manage the airplane’s trim.

Today, the aerospace giant has a massive backlog of more than 4,700 orders for the jetliner and its sales account for nearly a third of Boeing’s profit. But the decision to continue modernizing the jet, rather than starting at some point with a clean design, resulted in engineering challenges that created unforeseen risks.

• Feedback from Tom — I don't think people need to worry about Google's/Chrome's dominance the way we did about IE6. It's not just that Chrome is cross-platform and open-source, and (with Chrome Web Apps well behind us) sticks to the standards in a way that IE did not. Practically speaking, we must keep in mind that the browser is locked down on iOS in a way that didn't exist (and wouldn't have been tolerated) back then. This means that no matter how popular Chrome becomes, an importnat portion of mobile users must use Apple's browser (engine). But also, now matter how much effort, money Google puts into their web initiatives and in spite of their browser share dominance, they can lose big as they did with web components and webasm. That's the beauty of a standards based platform.

• Serverless Feedback from TomEnom — One thing you left out of your definition of serverless (IMO) that I find important is that it scales to zero. So if your lambda/function is not being used it incurs zero cost. I guess you could say that that is where serverless becomes literal.
• Install openSUSE on Digital Ocean — Unfortunately, Digital does not at present have an option for an openSUSE image. That doesn’t mean that you can’t use openSUSE on Digital Ocean, but it is going to be a little more work than most common Linux distributions.

• What Hooks Mean for Vue — You may read through this and wonder what Hooks have to offer in Vue. It seems like a problem that doesn’t need solving. After all, Vue doesn’t predominantly use classes. Vue offers stateless functional components (should you need them), but why would we need to carry state in a functional component?
• Hooks at a Glance – React — Hooks are functions that let you “hook into” React state and lifecycle features from function components. Hooks don’t work inside classes — they let you use React without classes.

• Nilay Patel on Twitter — Hi, I'm the nagging voice in the back of your head pointing out that it's pretty intense that Apple can simply decide to prevent people from running code on their phones.
• Essential .NET - C# 8.0 and Nullable Reference Types — Nonetheless, as it currently stands, and even after 7 versions of C#, we still don’t have a perfect language.
• Make your next C# project non-nullable — The naming is a bit confusing, because reference types have always been nullable, and that’s the whole problem. The novelty is that they can now also be non-nullable.
• Switch to errors instead of warnings for nullable reference types in C# 8 — Nullable reference types coming in C# 8 are a great addition to anyone’s toolbox. But if you tried it you probably know “just” warnings are produced. And sometimes you’d like to have errors instead of warnings, so the build fails hard or something like that. It’s surprisingly easy to do so.
