Maxime Buquet: Am I allowed to say no?
People often take photographs for granted. It does seem obvious in our society
that people like to appear with their friend on Facebook, TikTok, and what have
you.

Early on I started telling people I didn’t want to have my picture taken. It
has never really been clear why, not even to myself to be honest. It might have
been out of shyness – a trait that is still ever so present – or because I
didn’t like the way I look in them, or perhaps some other reason. But I kept
telling th … ⌘ Read more

Annotate PDFs on Linux
This post is about a GUI tool called pdfrankestein that
fills a gap on mostly Linux machines where a powerful and easy to use
PDF annotator does not exist.

Adobe Acrobat® on Windows and Mac allow you to add text, drawings and
signatures to PDF documents. This is useful when filling forms or
marking notes to send back to someone. Such a tool with similar
capabilities and easy of use does not exist on Linux. The reason that’s
often cited is that PDF is a c … ⌘ Read more

I didn’t get around to blogging about the fact that Miniflux recently got a new version. With it, if an entry doesn’t have a title, it finally shows a snippet of the content instead of just the URL as the title. A great new feature if you follow a lot of micro blogs. Regarding micro-blogs, I’m also in the process of reading Manton Reece’s book draft. ⌘ Read more

Sam Whited: Joanna
”`
Sipping my tea, I think back and remember Joanna:
Quietness isn’t the same for me now.

You came to America, wondering what you’d find:
Atlanta in a forest of broken dreams,
A people in turmoil, and no one seems to know why.
Communities falter before they’ve begun.

A lawnmower hums and I wake from my reverie.
I’d forgotten, about your America.

Driving to the North, far away from the city.
You looked for meaning in every farm passing by.
I bought you peanuts and gave you a tour of the mountains.

↳ In-reply-to » @prologic Re: Chat system, What if the base specification included a system for per-user arbitrary JSON storage on the server? Kind of like XEP-0049, but expanded upon.
