+# Achim Gsell: Coding Styles
+
+**Presenter:** Achim Gsell
+**When:** 3. February 2026; 11:00-11:45am
+**Where:** PSI OHSA/E13
+
+Coding style matters in software development because most code is read far
+more often than it is written—and usually by someone other than the original
+author. A consistent style makes intent obvious and helps the developers in
+writing better code.

+## <a id="Tool"></a>The tool I used to create the slides
+
+* I don't like Powerpoint an Co!
+* ASCII format.
+* Similar workflows as with software can be used.
+* For this slides: `markdown-to-slides`
+* It's on [Github](https://github.com/partageit/markdown-to-slides).
+
+---
+## Introduction
+
+* how I came across this topic and why I consider it important
+* once I had to fix an issue in the token ring driver in the Linux kernel
+  * it was surprisingly easy to navigate through the kernel sources ...
+  * to read ...
+  * and to fix it.
+  * The coding style was very helpful in this regard.
+* an experience at PSI
+  * a code developed by one (permanent) employee and PhD., Post-docs and and master students
+  * no coding style, no bugtracking, no code review
+  * the code was difficult to read, understand, maintained and extended.
+
+---
+## Why?
+
+* You read code more often than you write code.
+* In a team you should agree on some basic rules
+* otherwise the code is dificult to read and understand.
+* Good coding style helps you to write better code.
+
+---
+## A few general rules (not only for coding)
+
+### Line length
+
+```
+" ... it is widely accepted that line lengths fall between 45 and
+75 characters per line (cpl), though the ideal is 66 cpl ..."
+```
+
+```
+"The experience of the reader can also be considered as a factor
+when determining the count of characters within text lines. For
+novice readers, text lines should contain between 34 and 60
+characters, 45 being the optimal number. Texts for expert readers
+could contain between 45 and 80 characters, with an optimal count
+of 60 characters." 
+```
+[Wikipedia](https://en.wikipedia.org/wiki/Line_length#:~:text=In%20typography%2C%20line%20length%20is,%22%2C%20%22We%22)
+
+---
+### White space
+
+```
+"White space significantly impacts readability by making content
+more legible and easier to consume. Ample spacing between lines,
+paragraphs, and sections helps readers distinguish between
+different pieces of information, allowing their eyes to rest and
+preventing fatigue. It also helps guide the reader's eye and
+improves the flow of reading, leading to better comprehension. 
+Without appropriate white space, content can appear cluttered,
+overwhelming, and difficult to read." 
+```
+
+[Lenovo](https://www.lenovo.com/us/en/glossary/white-space/?orgRef=https%253A%252F%252Fwww.google.com%252F)
+
+---
+### Complexity
+
+```
+"Any intelligent fool can make things bigger and more complex. It 
+takes a bit of ingenuity – and a lot of courage – to move in the
+opposite direction. "
+```
+Albert Einstein
+
+
+=> Reduce things to the essentials and make them understandable.
+
+---
+### Don't re-invent the wheel
+
+* Choose an existing coding style/standard and adapt it to your needs - if it is really necessary.
+* Some simple rules can have a huge impact on code quality.
+* Don't be dogmatic with concepts like early returns, goto's in C, ...
+
+---
+## Some styles and standards for C/C++
+(See: [awesome C++](https://github.com/fffaraz/awesome-cpp)))
+
+* Coding Standards
+  * [Cert C++](https://resources.sei.cmu.edu/downloads/secure-coding/assets/sei-cert-cpp-coding-standard-2016-v01.pdf)
+  * [Misra C++ 2008](https://www.cppdepend.com/misra-cpp)
+  * [Autosar C++ 2014](https://www.autosar.org/fileadmin/standards/R21-11/AP/AUTOSAR_RS_CPP14Guidelines.pdf)
+  * [F-35 Fighter Jet's C++ Coding Standards](https://www.stroustrup.com/JSF-AV-rules.pdf)
+* Coding Style
+  * [C++ Core Guidelines](https://github.com/isocpp/CppCoreGuidelines) - "Official" set of C++ guidelines, reviewed by the author of C++.
+  * [C++ Dos and Don'ts](http://www.chromium.org/developers/coding-style/cpp-dos-and-donts) - The Chromium Projects > For Developers > Coding Style > C++ Dos and Don'ts.
+  * [google-styleguide](https://github.com/google/styleguide) - Style guides for Google-originated open-source projects.
+  * [Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html)
+  * [GNU Coding Standard](http://www.gnu.org/prep/standards/standards.html)
+  * [Linux kernel coding style](https://www.kernel.org/doc/Documentation/process/coding-style.rst)
+  * [LLVM Coding Standards](http://llvm.org/docs/CodingStandards.html)
+
+---
+## Python coding styles
+* [PEP 8](https://peps.python.org/pep-0008)
+* [Real Python](https://realpython.com/ref/best-practices/coding-style/$0)
+* [Google](https://google.github.io/styleguide/pyguide.html)
+
+---
+## Some general rules you should follow
+
+* Fewer rules are often better.
+* Be consistent
+  * it's less important where to place spaces, parenteses, etc
+  * same for CamelCase or foo_bar
+* Follow best practices for the language.
+* Use descriptive names.
+* A function should do one thing.
+* Functions should be short.
+* Complex functions should be even shorter.
+
+---
+## Comments
+
+```
+Generally, a comment is an annotation intended to make the code easier
+for a programmer to understand – often explaining an aspect that is
+not readily apparent in the program (non-comment) code. 
+```
+[Wikipedia](https://en.wikipedia.org/wiki/Comment_(computer_programming)
+
+---
+### Comments (Ccont.)
+
+Rule 1: Comments should not duplicate the code.
+
+Rule 2: Good comments do not excuse unclear code.
+
+Rule 3: If you can't write a clear comment, there may be a problem with the code.
+
+Rule 4: Comments should dispel confusion, not cause it.
+
+Rule 5: Explain unidiomatic code in comments.
+
+Rule 6: Provide links to the original source of copied code.
+
+Rule 7: Include links to external references where they will be most helpful.
+
+Rule 8: Add comments when fixing bugs.
+
+Rule 9: Use comments to mark incomplete implementations.
+
+Stackoverflow: [Best practices](https://stackoverflow.blog/2021/12/23/best-practices-for-writing-code-comments/)
+
+---
+## Linux kernel coding style
+
+[Linux kernel coding style](https://www.kernel.org/doc/html/v4.10/process/coding-style.html)
+
+* Linux: 8(!) spaces per level.
+* Max line length: 80 chars.
+* This limits the numer of levels - usually not more than 3 levels.
+* You have to structure your code better.
+* => use a function for a code block (even if they are called only
+  once)
+  ```
+  if condition:
+          do_this()
+  else:
+          do_that()
+  ```
+* Forget the performance penalty of calling a function (there are exception).
+* Use inline function with care (C/C++).
+* More functions also (usually) means: less arguments per function => easier to read and understand.
+  
+---
+## Examples Linux kernel
+
+* [core socket implementation](https://github.com/torvalds/linux/blob/master/net/core/sock.c)
+* [fsync() implementation in ext4 filesystem](https://github.com/torvalds/linux/blob/master/fs/ext4/fsync.c)
