Hacker News with Generative AI: Software Design

Comptime as Configuration (openmymind.net)
If you look at my httpz library, you'll notice that httpz.Server(T) is a generic. The type passed to Server serves two purposes. The first is to support an application-specific context - whatever instance of T passed into Server(T).init gets passed back to your custom HTTP handlers.

Go Is a Well-Designed Language (mattjhall.co.uk)
Go was designed at Google, where Russ Cox, Rob Pike, Ken Thompson and many others were working. Google was using Java and C++ at the time which the designers of Go felt were performant but hard to use. The compilers were slow, tooling was finicky and the languages had been designed at least a decade before. Cloud computing - large numbers of multicore servers working together - was becoming widespread.

Types are a basic tool of software design (2018) (tedinski.com)
One of my pet peeves is when someone makes like they’re going to talk about software design, and then… talks about comments. Or they focus on the details about how functions get written.

Lua is so underrated (bearblog.dev)
The more I learn about Lua's design and implementation, the more impressed I am. It's very rare to see software that does so much with so little code.

Visitor Pattern Considered Pointless – Use Pattern Switches Instead (nipafx.dev)
In modern Java, the visitor pattern is no longer needed. Using sealed types and switches with pattern matching achieves the same goals with less code and less complexity.

Ideas from "A Philosophy of Software Design" (16elt.com)
Almost a month ago, I created a telegram channel with the goal of reading tech books consistently, and sharing summaries of them. This week, I have finished reading the first book - “A Philosophy of Software Design” by John Ousterhout and shared all of the 21 chapter summaries in the channel.

Developing Developers (2015) (felleisen.org)
Northeastern offers a unique But see P.S. Uniqueness. curriculum on programming. Instead of the currently fashionable programming language, it focuses on explicit and systematic approaches to program design. To bring this idea across to the full range of Northeastern freshmen, the first course uses a simple teaching language that is tailored to our goals.

Consider Rexx for Scripting (2022) (opensource.com)
How do you design a programming language to be powerful yet still easy to use? Rexx offers one example. This article describes how Rexx reconciles these two seemingly contradictory goals.

A C++ Mixin System (jennyjams.net)
I've had this idea in the back of my head for a while of pervasively using mixins to add code and logic for more high level concepts, although this gets somewhat close to Rust style traits (and C++ concepts). This has existed in the back of my head for a long time as a way to model a framework or standard library implementaiton while also providing it for user types.

Make It Ephemeral: Software Should Decay and Lose Data (pocoo.org)
Most software that exists today does not forget. Creating software that remembers is easy, but designing software that deliberately “forgets” is a bit more complex. By “forgetting,” I don't mean losing data because it wasn’t saved or losing it randomly due to bugs. I'm referring to making a deliberate design decision to discard data at a later time. This ability to forget can be an incredibly benefitial property for many applications. Most importantly software that forgets enables different user experiences.

Why doesn't Roc have a Maybe or Option or Optional, or null or nil or undefined? (roc-lang.org)
The inventor of the null reference refers to it as his "billion dollar mistake" because it "has led to innumerable errors, vulnerabilities, and system crashes, which have probably caused a billion dollars of pain and damage in the last forty years."

Tiered support is an anti-pattern (2013) (gillardmoss.me.uk)
Back when the first internet bubble was bursting I had my first web development job. We thought we were sophisticated because we used Macromedia Drumbeat whose killer feature was, gosh, dynamic ASP and JSP websites. This put us a cut above those ‘amateurs’ who chopped huge TIFFs into static HTML using Fireworks (pfff)!

A word about systemd (2016) (skarnet.org)
systemd is becoming de facto a standard init system for Linux. But even this choice of words is treacherous, because systemd is much more than an init system. It's basically an integrated redesign of all the low-level userspace of a Linux system, with great plans to change how software is run and organized.
