_ rendering
release7.8.03.346.g1915.dirty after the first paragraph is rendered incorrectly as release<sub>7.8.03.346.g1915.dirty</sub>.Wed Jan 8 17:39:22 2025 - permalink -
This can be fixed by
#+OPTION ^:{}
will yield correctly rendered underscore characters.
#+begin_quote [[info:org#Export settings]]
‘^:’
Toggle TeX-like syntax for sub- and superscripts. If you write
"^:{}", ‘a_{b}’ will be interpreted, but the simple ‘a_b’ will be
left as it is (‘org-export-with-sub-superscripts’).

Complex Multiplication (CM)
The CM software implements the construction of ring class fields of imaginary quadratic number fields and of elliptic curves with complex multiplication via floating point approximations. Additionally it provides an implementation of the fastECPP algorithm for proving primality of integers. It consists of libraries that can be called from within a C program and of executable command line applications. For the implemented algorithms, see A. Enge, The complexity of class polynomial computation via floating point approximations, Mathematics of Computation 78 (266), 2009, pp. 1089–1107.Sun Dec 29 21:50:44 2024 - permalink -

GitHub - fukamachi/cl-project: Generate modern project skeletons
From the author's description:Wed Dec 18 13:27:04 2024 - permalink -
1. Flexible templates
CL-Project supports more parameters to embed, by using CL-EMB to represent the skeleton files (See "cl-project/skeleton/").
2. One package per file style (Modern)
A modern CL project should be in accordance with some rules. For instance, one file must have one package in it.
3. Recommends unit testing
Modern projects should have some unit tests. CL-Project generates a system for unit testing, so you can begin writing unit tests as soon as the project is generated.- https://github.com/fukamachi/cl-project

GitHub - org-noter/org-noter: Emacs document annotator, using Org-mode
Org-noter’s purpose is to let you create notes that are kept in sync when you scroll through the document, but that are external to it - the notes themselves live in an Org-mode file. As such, this leverages the power of Org-mode (the notes may have outlines, latex fragments, babel, etc…) while acting like notes that are made inside the document. Also, taking notes is very simple: just press i and annotate away!Thu Dec 12 13:08:41 2024 - permalink -- https://github.com/org-noter/org-noter
