so one of my big goals for Exigy - my graphical IDE and software development toolkit for lua/love2d - was integrating networking

i've never written a line of networking code in my life until two weeks ago. learning network code necessitated writing Events-driven code, which was mostly new to me too.

i needed some kind of 2d game to test out the network code, so i spent a couple of days hacking together a mini Lunatic Fringe game, if you remember this old classic After Dark module.

for the first time since i was in high school 30 years ago, i had to re-learn trigonometric theory. just making that little ship turn and thrust in the right direction took me WAY longer than i'm comfortable admitting to 😬

these two lines should probably be tattooed to my forehead:
xPositionIncrement = -cos(shipAngle)
yPositionIncrement = sin(-shipAngle)

so as of today, Exigy now has server-client networking over UDP. 🤞 i'll be able to get a dollar store quality Lunatic Fringe server up and running in the next few days to test out the networking code

News includes Mark’s new Sagents AI agent library, @josevalim on why @elixirlang is best for #AI, LiveDebugger v0.6.0, Elixir salary analysis, new #MCP server implementations, #Lua for Elixir revamp, and more! #ElixirLang https://www.youtube.com/watch?v=H1iyBresVkM

I will admit to being a bit surprised that #lua isn't a top choice for other languages, making me again think I should put together a talk on "What Python Could Learn From Lua" for @pycon or @NorthBayPython

I will be curious to see if it makes the list of "other"

Metaplace Postmortem (2008): "Snow Crash is a Lie"

jussst after i wished there had been some kind of postmortem done on raph koster's Metaplace, i found out that he himself presented one at GDC 2008!

https://www.gdcvault.com/play/34/Metaplace-Postmortem-Reinventing

if you're not familiar with Metaplace, I don't blame you. It was an attempt at making a web-based graphical MUD/MUSH/MOO/MMO virtual world development system that could be played online in any browser. it disappeared almost as quickly as it was developed.

what i find most fascinating about it was that it had a Lua-based scripting system called Metascript. it featured some really hot runtime behaviours like being able to load/unload scripts on any object. (which means you never needed to recompile to test your world)

New account, new #intro post.

My name is Zef. I’m #Dutch, but for the last 15 years have been living in #Poland. I’m married and have three sons.

I’m the #CTO at fixly.pl, a Polish services (handymen etc.) reverse market place. I also write alt.management.

As a hobby, for close to 4 years, I’ve been developing @silverbulletmd a #selfhosted #OpenSource #markdown based note taking app that is programmable with #Lua. I’m currently finding ways to make spending more time on #SilverBullet financially sustainable as its user base has been growing significantly over the years.

In addition, I’m increasingly interested in the #selfhosting community, looking for more ways to break away from #BigTech and to gain more #DigitalSovereignity by regaining control and ownership of the digital assets I care about.

just updated litehug to include examples for using it from #lua for #sqlite queries

https://git.sr.ht/~technomancy/litehug

not that you couldn't before, but now it's a lot more obvious how it works... feedback welcome!

In #Wikimedia land, I created my first #Lua module in #WikimediaCommons: https://commons.wikimedia.org/wiki/Module:NHCP_marker_depicts_inscription

This module does all the heavy lifting for enhancing file pages of photos of #HistoricalMarkers of the #Philippines 🇵🇭 with #Wikidata items. It provides a way to point to the Wikidata item about the marker and to show the actual text inscribed in the marker. This is all done by just adding the {{NHCP marker depicts inscription}} template. 🧵 1/3

@writefreely the project seems very much technologically and value aligned with @silverbulletmd: backend written in #golang, simple single binary deployment, open source, open standards, minimalist design. This may well become my recommended way of sharing content from #SilverBullet

But again, first need to hack together a proper integration in #lua. Seems straight forward enough, already got auth working.
