Hm cool.
Es gibt für #texlatex ein Braille Paket.Damit kann ich Texte schreiben und es wird automatisch in Braille übersetzt. 😃
Wenn ich jetzt keinen speziellen Braille Drucker habe, gibt es mit normalen Laserdruckern oder Nadeldruckern ggf. einen Trick, wie ich bspw. so drucken kann, dass sich ein Relief ergibt?
Ich meine manche Druckerzeugnisse aus Laserdruckern hinterlassen ein leichtes Relief.
Kann man das durch Mehrfachdruck an gleicher Stelle verstärken? 🤔 -

I updated my phone/tablet-sized PDF version of Edward Gibbon’s ‘Decline and Fall of the Roman Empire’: https://archive.org/details/gibbon_declineandfall
Previously there were some rough edges: a few awkward spacings and line breaks, some pushing side-headings out of position. I think these are all resolved now, but I might have missed some among the 3858 pages. :-)
LuaLaTeX source code: https://codeberg.org/ajcain/gibbon_declineandfall
The code uses the interfaces created by the LaTeX tagging project, so it is an accessible #TaggedPDF. The font is @mc_wiki’s beautiful Garamontio.

For newbies feeling hesitant or frustrated about #Emacs and its Lisp flavor. tl;dr #Foss #lifelonglearning victories!
In 2010 or so I watched an interview with the immortal Carsten Dominik, creator of Org mode. He made an offhand remark to the effect of "I just love coding in Emacs Lisp, it's just how I think, it's just so natural, don't you agree?" And I was very unhappy. Because I could not agree. That discouragement stuck with me.
My wife always says "the time is going to go by anyway," and this is wisdom. By 2023 I had written "org-teach" for producing classroom materials, shared it at EmacsConf, actually used it in the wild. Others around here have done similar, @randyridenour @ericsfraga @asilata sorry if I'm forgetting you.
Long story short, the underlying #TeXLaTeX core couldn't do #taggedpdf until 2025. I asked on here for help and @yantar92 went to the mailing list and before I could say meta x @paaguti and @schuemaa had us all sorted out. So grateful!
https://codeberg.org/paaguti/pdf-ua2-tests/src/branch/main/ltx-talk-test
With these significantly changed dependencies I decided to rewrite the jank that was org-teach from scratch. And it feels like lightning shoots from my fingertips now. I can implement functionality almost as fast as I can think of it. Too messy to share quite yet. But this kind of workflow and software self sufficiency feels like a superpower. Emacs Lisp just feels natural now. After only a decade and a half!
But seriously, all my progress is thanks to this community.

Anzeichen, an denen man erkennt, dass eine studentische Arbeit mutmaßlich mit KI-Unterstützung geschrieben wurde oder Medienkompetenz komplett fehlt, Teil 73:
Auf der Titelseite wurde das Fakultätslogo aus der eingescannten Aufgabenstellung als schiefe Rastergrafik genutzt, obwohl man das Logo natürlich auch auf der Webseite (https://www.cd.ovgu.de/Fakult%C3%A4ten/Elektrotechnik+und+Informationstechnik.html) oder sogar ganz einfach in unserer #TeXLaTeX-Vorlage (https://de.overleaf.com/latex/templates/guidance-on-the-preparation-of-degree-theses/zvbvgkspxsvh) findet.

Big update to ‘Form & Number: A History of Mathematical Beauty’: the PDFs are now *tagged* (plus various minor improvements).
A #TaggedPDF contains hidden extra semantic information to assist screen-reading software etc., including alt text for diagrams+images (in the case of ‘F&N’, 552 pieces of alt text were required, some quite lengthy).
The new version is available (#OpenAccess as always) at: https://archive.org/details/cain_formandnumber_ebook_large
Feedback from users of screen readers would be very welcome!
Creating this version has been possible because of the ongoing LaTeX tagging project [https://latex3.github.io/tagging-project/] (thank you to the LaTeX team and other contributors!). I have been adapting my own #LuaLaTeX styles [https://codeberg.org/ajcain/minos] to use the new interfaces.

My #semigroups lecture notes ‘Nine Chapters on the Semigroup Art’ are now accessible #TaggedPDF files: https://archive.org/details/cain_semigroups_a4_screen
I have been working to update my LuaLaTeX style "minos" [https://codeberg.org/ajcain/minos] to use the new interfaces created by the LaTeX tagging project, and this is the latest outcome [https://latex3.github.io/tagging-project/].
Besides adding "alt" text for the (many!) diagrams, there were only one or two small changes to be made to the LaTeX code of the document itself (which was mostly written in 2012, long before the tagging project started). Essentially all the complicated changes were in the style. This is a testament to the work of the tagging project team.
The files pass VeraPDF validation, but feedback from users of screen readers would be very welcome.

Another update to my #LuaLaTeX style "minos", used in ‘Form & Number: A History of Mathematical Beauty’ and my other books (links in profile).
Git repository: https://codeberg.org/ajcain/minos
Download documentation or source .zip/.tar.gz: https://codeberg.org/ajcain/minos/releases
Improvements mostly concern #TaggedPDF-related features:
- Sidenotes are now tagged as *notes* (same as footnotes), not as "Aside" (the default for marginal content).
- The theorem number appears in the proof heads even when \DocumentMetadata is used — in the previous version I had not integrated this feature into the new interfaces for theorem-like environments.
(The number also appears in the QED symbol, which is a long-standing feature I would like to highlight. I think is useful with nested proofs; example from docs attached.)

‘Bertrand Russell & Trinity: A college controversy of the last war’ is a pamphlet written by G.H. Hardy in 1942, giving an account of the dismissal of Russell from his Trinity College lectureship in 1916 following his criminal conviction for anti-war political activity. (Hardy was at the time a fellow of Trinity and opposed Russell's ouster.)
Since there was no downloadable ebook, I made a re-typeset version, which I have just updated: https://archive.org/details/hardy_russellandtrinity
Creating this version was an exercise for me to learn how to (start to) adapt my LaTeX styles to the new interfaces created by the ongoing LaTeX tagging project [https://latex3.github.io/tagging-project/]. (A #TaggedPDF contains supplementary information to assist screen reading software, data extraction, etc.)
The updates are mostly behind-the-scenes source code changes, particularly to use the new template interfaces for sectioning. I have made the source available in case it is useful as an example to others: https://codeberg.org/ajcain/hardy_russellandtrinity

I made a edition of Edward Gibbon’s ‘Decline and Fall of the Roman Empire’ as a phone/tablet-sized PDF: https://archive.org/details/gibbon_declineandfall (3863 pages!)
LuaLaTeX source code: https://codeberg.org/ajcain/gibbon_declineandfall
The style uses the interfaces created by the LaTeX tagging project, so (at least in theory), it is an accessible #TaggedPDF.
The font is @mc_wiki’s beautiful Garamontio.

Der Löwe und ich machen uns startklar für die #CLT2026 (@clt_news)
Mal sehen was dieses Jahr so für Fragen am #DanteEV Stand vorbeikommen und was wir so dazu lernen. Also falls ihr zufällig gerade die eine oder andere Frage dabei habt... Wir werden versuchen zu helfen. Bei den Themen wie #TeX & Friends, insbesondere #TeXLaTeX, #eRechnung, #ZUGFeRD , #TaggedPdf ist die Wahrscheinlichkeit, relativ hoch, dass das klappt.

My new #LuaLaTeX package: lua-simple-wrap
This package allows easy wrapping of text around small figures, pull quotes, etc. (See attached image.)
Unlike (I think) all other LaTeX packages for wrapping text around things, the wrapped object can be specified at its natural place in the text, and the package works out where it should appear. Virtually all the processing happens on the Lua side.
The package is semi-experimental, and definitely requires more work before I submit it to CTAN, but the basic functionality is in place and seems to be working well. In particular, tagging support (for producing accessible PDFs) is already present.
Git repository: https://codeberg.org/ajcain/lua-simple-wrap
Download documentation and built package: https://codeberg.org/ajcain/lua-simple-wrap/releases
If you try it, feedback would be much appreciated!

[1/2] Ulrike Fischer showed a summary of the #TeXLaTeX News including a preview for the next release in June.
Of course she included achievements of the tagging project which included the new template based implementation of sectioning commands.
And the status of accessible math typesetting using #MathML https://www.latex-project.org/news/2026/03/05/PDFA-press/ which is a huge step towards completely accessible documents.

@frischefarbe zeigt im nächsten Mini-Vortrag eine andere Spielerei. Ihr findet sie unter https://hobby.boxesandglue.dev/ und macht Werbung für #Metapost, was tatsächlich an vielen Stellen etwas mehr Aufmerksamkeit verdient hätte.
Im #TeXConTeXt Umfeld wird es deutlich mehr genutzt, aber bei #TeXLaTeX haben gerade #TikZ & Co mehr Nutzung.

I made a little extension to my Python-based LaTeX math renderer so it can be used to draw equations and Sympy expressions directly in the terminal as sixel graphics. Install with `pip install sixelmath` and give it a try! (in a sixel-supported terminal, of course).

@ctietze I need to be able to make slides from #OrgMode files. But #Beamer cannot (and will not) be made to produce #taggedPDF output (thanks, @mxp). So rather than bang my head against #TeXLaTeX, I took a step back.

NEW POST (as promised): "Org mode, LaTeX, and tagged PDFs: producing accessible documents"
#Emacs #OrgMode #accessibility #a11y #debian #TeXLaTex #taggedPDF

[Howell breathes a long relieved sigh]
Before and after.
Canvas' infamous automatic ratings of #accessibility. In the proud bean-counting brain-dead tradition of provosts and deans, the thing they can measure is the thing we must make number-go-up.
Lots of steps to get Debian to run #texlive2025. Then a few steps to configure Org properly to export #TeXLaTeX that produces #taggedPDF output.
I promise the Fediverse I will write up all the steps and make a blog post.
tl;dr thanks to Dr. Kenny Ballou at Cal State San Marcos https://kennyballou.com/blog/2025/08/tagged-pdfs-org-export/index.html

Big update to the annotated edition of G.H. Hardy's ‘A Mathematician's Apology’: the PDF is now *tagged* (plus various minor improvements).
(A #TaggedPDF contains extra semantic information to assist screen-reading software etc.)
The new version is available (#OpenAccess as always) at https://archive.org/details/hardy_annotated
The LaTeX tagging system is still under development [https://latex3.github.io/tagging-project/], but I have been making progress in adapting my LaTeX styles to be tagging-compatible.
For the annotated ‘Apology’, I also had to re-implement a subset of the functionality of the "manyfoot" package (which is currently not tagging-compatible), because there are two different kinds of footnotes in the annotated ‘Apology’. (Hardy's original footnotes and the annotations.)
Although the PDF passes VeraPDF validation, there may of course be mistakes in the tagging. Feedback, especially from users of screen readers, would be much appreciated, especially because I now hope to add tags to ‘Form & Number: A History of Mathematical Beauty’ [https://archive.org/details/cain_formandnumber_ebook_large].

(Hardy was at the time a fellow of Trinity and opposed Russell's ouster.)
I have uploaded a re-typeset version of Hardy's pamphlet to the Internet Archive [https://archive.org/details/hardy_russellandtrinity].
Creating this version was an exercise for me to learn how to (start to) adapt my LaTeX styles to the new interfaces created by the ongoing LaTeX tagging project [https://latex3.github.io/tagging-project/]. (A #TaggedPDF contains supplementary information to assist screen reading software, data extraction, etc.)
Also, Hardy's work is in the public domain; there seemed to be no downloadable ebook version of this pamphlet; and I thought that it would be a useful companion to the ‘Annotated Mathematician's Apology’ [https://archive.org/details/hardy_annotated].
I have made available the #LuaLaTeX source code on #Codeberg, in case anyone is interested in how the style was created: https://codeberg.org/ajcain/hardy_russellandtrinity

A new version of my LuaLaTeX package ‘marginalia’ is now available on CTAN. [https://ctan.org/pkg/marginalia]
This package allows the placement of marginal notes (or other marginal content) anywhere, without \marginpar’s limits, and automatically adjusts positions to prevent either overlaps or content being pushed off the page, and uses key–value settings that allow fine-grained customization.
The main change in this new version is tagging support. (A tagged PDF contains supplementary information to assist screen reading software, data extraction, etc. #LaTeX is in the midst of a multi-year development project to add tagging support. [https://latex3.github.io/tagging-project/])
Credit for explaining how to add tagging support is due to Ulrike Fischer of the LaTeX team.

The interactive calculation sheet for #engineering, based on #emacs, #orgmode, #texlatex and #sympy is available in English [1], although the blog article is in German [2]. The template is also in English [3].
#Orgmode is so impressive, you could use #maxima, #octave, #gnuplot, #graphviz and almost 40 other languages with all their libraries right out of the box [4].
Have fun!
