GladTeX-ng - Embed LaTeX Quality Images Into HTML

Posted by Sebastian Humenda at 20/08/2015 (21:36)

I recently struggled to get GladTeX working on Windows which is a real pain with the current mixture of C/Perl. It's possible to get a binary out of GladTeX and the required subprogram eqn2img, but on some systems it would not terminate when processing a .htex file. Even though I have been trying to avoid this step, I finally decided to rewrite GladTeX in pure Python, because that brings many benefits. ...

Mate - An Accessible Alternative To GNOME 3

Posted by Sebastian Humenda at 16/07/2014 (10:45)

I am generally no friend of continuing dead technology, as GNOME 2 was termed. I payed little attention to the rumors that Mate, a GNOME 2 fork, was under active development. Since in recent Debian Unstable, the GNOME Shell accessibility experience is very poor and GNOME-shell seems to have a lot of bugs, I've tried out Mate and I will present some (quick) notes about what works. This article is of course about accessibility, but also covers some aspects of GNOME-shell and Mate in general. ...

copy (clipboard)-text between a tty and a GUI

Posted by Sebastian Humenda at 02/04/2014 (16:35)

For blind programmers using text editors like Vim, the command line is in most cases the only convinient work environment. On the other hand some tasks are not possible on a raw tty, therefore a GUI is necessary. Copying text between a tty and a X session is more or less a pain. In this short article, I'll describe xclip and some convenient ways to use it with Vim / ZSH / GNU screen. ...

GladTeX - embed LaTeX-quality equations in HTML

Posted by Sebastian Humenda at 16/03/2014 (13:31)

Some months ago I searched for a solution to embed equations in HTML together with the LaTeX-equation in the alt-tag (alternative text). This allows blind people to read documents with equations together with their sighted colleagues. Pandoc finally gave me a hint, since it supports conversion from Markdown to HTML with the --gladtex option. So I learned about GladTeX. I patched this program. ...
