A Lingual Fractal of itself. This Lingual Fractal generates a square based off the size of each word and rotates, creating a beautiful and chaotic checkboard pattern.

It's the little things...

Like simultaneously running 100 #http #microservices from a single #PowerShell process on a #RaspberryPi, with plenty of box to spare.

#WebDev with #PowerShell and packages is OP.

Questions? Comments? Thoughts?

Just seeing how many servers I can run without too much trouble.

Each instance is packing the subdirectories into a System.IO.Packaging.ZipPackage, then creating a System.Net.HttpListener to listen for requests, and then launches a ThreadJob with Start-ThreadJob to serve up each request as it comes in.

For extra cool points:

Because each job has a pointer to the package, it is possible to update the package being served on-the-fly.

Happy #Halloween from #PowerShell and #Turtle #Graphics #TurtlePower #Fractal #MathArt

New build coming after a few more release notes.

This might be one of the most beautiful animations I've ever made, and it's only 2.25kb of #SVG

#Turtle #Graphics in #PowerShell are far too fun!

Spending a bit of my day making #PieGraphs on a #RaspberryPi (and just now realizing the meme factor)

#Turtle #Graphics in #PowerShell just keep getting better and better!

New drop coming in -lt ([DateTime]::Now.AddDays(7)) 😉

~💯

The classic PowerShell Dark Blue (#012456) ?
Or the lighter blue used in community projects (#4488ff) ?
Or the mid blue (#224488)?

~~~PowerShell
turtle square 200 fill '#4488ff' save ./LightBlue.svg fill '#012456' save ./DarkBlue.svg fill '#224488' save ./MidBlue.svg
~~~

Your favorite?

PowerShell Dark Blue - the original Windows PowerShell and PowerShell ISE console color - #012456

PowerShell light blue - used in many community projects - #4488ff

PowerShell mid blue (#224488). Often used as an accent color in community projects.

I think I stumbled upon an #LSystem used to create some of the creatures in #SpaceInvaders

#Turtle #Graphics continue to be a beautifully fun use of #PowerShell

Should I add this LSystem to an upcoming build of #Turtle ?

What shapes do you want to draw?

That's the PowerShell Hero.

There are comics.

And some people have 3D printed really nice copies.

The PowerShell hero watches over Seattle.

Today's #Math #Geometry #Epiphany, courtesy of #Turtle #PowerShell

Backwards is a reflection of forwards.

To reflect a shape, simply provide a negative value.

turtle rotate 60 SierpinskiTriangle 42 5 SierpinskiTriangle -42 5 stroke '#4488ff' fill '#4488ff' save ./SierpinskiTriangle.png

A Sierpinski triangle reflecting itself.

This works because going backwards instead of forwards will effectively reverse every rotation within the graph. That is: walking forward -10 steps at 90 degrees becomes the equivalent of walking forward 10 at 270 degrees.

Lol I think I've made a #SVG #Fractal that reliably kills #chromium when rendered. 😂😭😕😉

Who do I report this to?

Got a book on #Turtle that's slightly older than I am, and look at what it had inside as a bookmark.

Anyone want to guess what that is? You win bonus points if you're under 30.

Talk about a blast from the past of computing.

This computing book is so old it uses a punch card as a bookmark.

This nifty little site is great for discovering repositories and developers people are talking about on #AtProto / #BlueSky!

Ah, the random weirdness of ranking #GitHub repositories on #AtProto

As I've currently got ranking set up Zummoner is rank 1666.

github.com/day50-dev/Zu...

Of course, by mentioning this repository, I might have broken the spell. 😅🤞

Working on AtGitHub.com and it just so happens that a Repository named Zummoner is rank 1666.

#Screenshot #Irony :

@arstechnica.com writes about #Meta telling the #FTC "users like ads", while sandwiching the paragraph in between two ads.

If companies don't want us to use ad blockers, how about showing us fewer and more relevant ads?

ArtsTechica complains about too many ads on Facebook while showing too many ads.

Holy crap:

The #USD is down €0.07 / ~7% since January.

You can see the economic decline from space.

Also, just saying, previous four years seem pretty good / stable.

The second half of the video, and a links to the projects that made it possible:

obsproject.com #OBS

obsproject.com/forum/resour...
OBS-ShaderFilter plugin (for the #PixelShaders)

github.com/StartAutomat...

(to control OBS from #PowerShell and fine-tune the shaders)

I saw the video for #Love by #OKGo and knew what else it needed:

Polar reflections.

Lucky for me, @exeldro.com makes a few #PixelShaders for #OBS, and I've got a #PowerShell module for OBS.

Less lucky: #BlueSky is picky about video uploads.
