I had a call from a scammer the other day

Me: โ€œHello.โ€

NOT-Microsoft support: โ€œHello. This is Bob Bobson from Microsoft Support. We are seeing a lot of virus activity from your device.โ€

Me: โ€œOh no. My device? Are you sure?โ€

NOT-Microsoft support: โ€œOh yes, we have many reports.โ€

Me: โ€œOh jeez. How can I fix it?โ€>;
NOT-Microsoft support: โ€œItโ€™s OK sir. We can help you right now. Are you in front of your device sir?โ€

Me: โ€œYes. I was just about to use it. Iโ€™m glad you called.โ€

NOT-Microsoft support: โ€œYes sir, we are going to help you. Can you please push the Start button?โ€

Me: โ€œI think it's already on.โ€

NOT-Microsoft support: โ€œOkay, sir. Now you want to click on Control Panel.โ€

Me: โ€œI donโ€™t see that.โ€

NOT-Microsoft support: โ€œDo you see a bunch of information above the Start button?โ€

Me: โ€œYes.โ€

NOT-Microsoft support: โ€œThat is your Control Panel.โ€

Me: โ€œWow, I didnโ€™t realize it had a name.โ€

NOT-Microsoft support: โ€œYes sir, now press on Internet Options.โ€

Me: โ€œYeah, I definitely donโ€™t see any Internet options. I donโ€™t think I purchased that feature. This is just a cheap one.โ€

NOT-Microsoft support: โ€œThey all have the Internet sir. Press the Start button again.โ€

Me: โ€œOK, itโ€™s the same as before.โ€

NOT-Microsoft support: โ€œThatโ€™s OK sir. We are going to restart your device. Can you please turn it off?โ€

Me: โ€œUmmmโ€ฆI donโ€™t know how. Iโ€™ve never turned it off. Since I bought it, it just kind of stays on all the time.โ€

NOT-Microsoft support: โ€œThere must be an off button on your device. How do you stop it when itโ€™s running?โ€

Me: โ€œIn those cases, I usually press the big button.โ€

NOT-Microsoft support: โ€œOK sir. Please press that button.โ€

Me: โ€œOk.โ€

NOT-Microsoft support: โ€œIs your device off?โ€

Me: โ€œNo. The door popped open.โ€

NOT-Microsoft support: โ€œDoor? Is there a disc inside the door?โ€

Me: โ€œNo, thereโ€™s a burrito.โ€

NOT-Microsoft support: โ€œWhy is there a burrito in your computer?โ€

Me: โ€œComputer? I thought you said this was microwave support.โ€

Night Shift ๐ŸŒ™ for #windowfriday

This took me much longer to edit than I would care to admit - even if it is minimalistic. So, if you have any critiques on it, talk to me about it in a couple of months when I've recovered from the pain. ๐Ÿ˜‚
It's not great, but it's something! You might have seen another photo of this building a few months ago when I photographed the reflections of clouds on its faรงade.
Oh, the person standing there had just put on their coat and I was very happy they were visible! โœจ

A photo of a rectangular five storey building made of windows with a black frame. The window features a grid of vertical and horizontal black bars. The panes are illuminated in gradient shades of pink and peach. A single small black silhouette of a person, is centered in the middle pane.

I think that's the most annoying thing, to me: You can't debloat Linux because the package management tools forbid it.

Cups is pretty damn good, I have nothing against the project, it's *way* better at just working than any print stack in the commercial operating systems, but if I'm not printing then I should be able to remove it from my computer that I own in my own house.

Try it, though, and literally *everything* vanishes, because apparently you can't watch a video without ffmpeg (in case you need to transcode it for streaming), and ffmpeg can't work without imagemagick (in case you're tired of actual video formats and wanted to animate a series of .jpg files) and imagemagick can't work without the inline documentation system (in case you can't just google the actually readable online documentation in 2025), and the documentation system can't work without ghostscript (in case you wanted to convert your man pages to PDF for printing in a big binder on your desk in the year 2025), and ghostscript can't work without cups in case you wanted to convert your PDF to PS and the only reason you would want a postscript file is to pipe it directly to your laser printer that's enterprise enough to still have a postscript interpreter.

client to server is severely impaired by "authorized fetch" because usually before building an Activity to send to an Actor's outbox, one would want to validate some of the IRIs they operate on.

For example, I want to build a Follow request for a remote actor (represented by an IRI or webfinger resource). My client won't allow me to add this random IRI as the Object of the Follow and just send it, it wants to dereference it and make sure it's a valid Actor.

However when authorized fetch is enabled on that actor's instance, this mechanism will fail, because the client can't generate a valid HTTP Signature for its request. :(
