See also: My talks, my contributions to Free Softwares and my old projects. 1.1 Websites • Python Development (created in Juny 2018) • Victor Stinner’s Blog 3 (new blog, created in 2015) • Victor Stinner’s Notes (this site, created in 2014) 3 Victor Stinner’s Notes Documentation, Release 1.0 1.2 Documentation • Faster CPython (source code: faster_cpython at github) • Programming with Unicode (source code: unicode_book at github) 1.3 Python Projects • fatoptimizer: static optimizer for Python 3.6 using function specialization with guards. It is implemented as an AST optimizer. It is part of the FAT Python project. • bytecode: API to modify Python bytecode, and a peephole optimizer. • pyfailmalloc: Debug tool for Python injecting memory allocation faults to simulate a low memory system to test how your application handles MemoryError exceptions. • sixer: add Python 3 support to Python 2 applications using the six module. • Hachoir: Python library that allows to view and edit a binary stream field by field. In other words, Hachoir allows you to “browse” any binary stream just like you browse directories and files. A file is split in a tree of fields, where the smallest field is just one bit. 1.4 Other Projects • “misc” repository: – my “dot” files, configuration files: bashrc, hgrc, gitconfig, etc. – some command line program: apply_patch.py, scm.py – some Python scripts – some shell scripts: apt_get.sh, fedora_new_install.sh 4 Chapter 1.
