ZenZX Preview Release

I thought I'd give people something better than promises to toy around with. Here's a very early, very rough, very green preview release of ZenZX.

ZenZX is a ZX Spectrum emulator written in Go with a focus on ergonomics and modular, understandable code. It's partly based on my other emulation project called zen80, a highly compliant instruction-stepped Z80 emulator.

See the README included in the .zip file and please let me know if you like anything about it, or if you hate anything about it. At this time, and because countless bugs are yet to be corrected, and I'm aware of hundreds of them, I'm not lacking insights of the type "It has a bug". The kind of useful feedback I'd like to get is more about ergonomics and whether you would use a different key mapping, keyboard shortcuts, colours, etc. Any user-facing ideas you would like to see one day, that would be useful.

I'm really puzzled at some #GoLang "conventions":
https://github.com/mholt/archives/issues/3#issuecomment-3212123684

In this issue, a smaller-than-produced-value type is exposed on a factory API: this would make sense if coding defensively, to reduce the API surface, but not here, IMO.

Forcing consumers to do runtime upcasting because of a convention feels wrong, but I'm perhaps missing part of the picture somewhere.

To me, making something "fail at compile time, when wrong" is a massive value proposition for a compiled language.

Draw UI in plain text → get working Deluxe UI widgets.

Introducing guiscii: Look mum, no XML!!! Refocusing now to improve the GUI code so I can ship proper UIs in my tools.

Happy to see, I've once again made it to the Golang Weekly. This time, with gomjml: https://www.golangweekly.com/issues/566

“Container-aware GOMAXPROCS” by Michael Pratt and Carlos Amedee — https://go.dev/blog/container-aware-gomaxprocs

This is where the Go generics dream goes to die ...

Why... does #Golang use capitalization to indicate whether a function is exported in the package or not? Honestly #Java's public/private is more sane...

I wrote an article about the primacy of the package as an organizing concept in Go. It's aimed at developers from other ecosystems, covering how old habits can lead to unidiomatic code when in a foreign land.

The post focuses on the "why" of the Go ecosystem context, not just the rules. And yes, there's some Angry Matt profanity peppered in there for good measure.

Inspired by choosing WriteFreely for a blogging platform, I decided to look into the Go programming language. I've gotta say, I'm really enjoying it, and I don't remember being pulled in by a language this much since I first learned C, many years ago.

I've almost finished working through "Let's Go" by Alex Edwards (Which is currently on sale). Typically I don't enjoy tutorial style books, preferring reference books, but this one is a great primer for language concepts

I was interviewed by Protesilaos Stavrou for his "Prot Asks" series! You can watch it here: https://protesilaos.com/codelog/2025-08-17-prot-asks-erik-emacs-1990s-portland-oregon-podcasting/ #emacs #pdx #1990s #programming #lisp #golang

Started experimenting with the idea of porting #OutboxKit to #GoLang

Not sure if it's very idiomatic #Go, given me being so used to #CSharp #DotNet, but hopefully it's not too far

My shitty ISP (spectrum) decided instead of a web-page to list all the devices on my network it was a good idea to force me to use a shitty app that takes forever to load and requires me to log into my spectrum account.....

So I put together my own dashboard on the raspberry pi that scans the local network and populates a list for me.

Screw you spectrum!

Added a new release of gomjml that adds significant performance improvements via opt-in template caching: https://github.com/preslavrachev/gomjml/releases/tag/v0.5.0

I *suspect* (but have not verified) that the results of net.InterfaceByName are not valid indefinitely (internally, the package uses a buffer pool), which would explain why at some point my DHCP client started sending requests for *some other MAC address*

Does this ring a bell with other #golang folks by chance?

https://github.com/rtr7/router7/commit/0b9afc92733d63e544afee6c630a3eff120fb6e0 is the commit
