A next-generation package manager called Nix provides a simple distribution-independent method for deploying a binary or source package on different flavours of Linux. Even better, Nix does not interfere with existing package managers. Nix allows different versions of software to live side by side, and permits sane rollbacks of software upgrades. Nix is a useful system administration tool for heterogeneous environments and developers who write software supported on different libraries, compilers, or interpreters. Why provide yet another package manager? Because current package managers fall short in the upgrade cycle. Everyone gets burnt by software dependencies, at some point. In particular, with a major release of any given distribution, many people choose not to upgrade until it is time to do a fresh install. With Nix, upgrades are always safe: they don't overwrite previously installed packages. This means previous versions will continue to work, and you can easily roll back.

Bibliographies in LaTeX using BibTeX for sorting only. The biblatex package is a complete reimplementation of the bibliographic facilities provided by LaTeX in conjunction with BibTeX. It redesigns the way in which LaTeX interacts with BibTeX at a fairly fundamental level. With biblatex, BibTeX is only used to sort the bibliography and to generate labels. Instead of being implemented in BibTeX's style files, the formatting of the bibliography is entirely controlled by TeX macros. Good working knowledge in LaTeX should be sufficient to design new bibliography and citation styles — there is no need to learn BibTeX’s postfix stack language. Just like the bibliography styles, all citation commands may be freely (re)defined.
The cb2Bib is a free, open source, and multiplatform application for rapidly extracting unformatted, or unstandardized bibliographic references from email alerts, journal Web pages, and PDF files. The cb2Bib facilitates the capture of single references from unformatted and non standard sources. Output references are written in BibTeX. Article files can be easily linked and renamed by dragging them onto the cb2Bib window. Additionally, it permits editing and browsing BibTeX files, citing references, searching references and the full contents of the referenced documents, inserting bibliographic metadata to documents, and writing short notes that interrelate several references.
Referencer is a Gnome application to organise documents or references, and ultimately generate a BibTeX bibliography file. Referencer includes a number of features to make this process easier: * Smart web links Referencer uses documents' metadata to provide handy links to the document's web location — no need to maintain your own bookmarks. * Import from BibTeX, Reference Manager and EndNote No need to start from scratch — Referencer will import your existing bibliography files using the BibUtils library. * Tagging No need to organise your documents into rigid directory trees — with Referencer you can use tags to categorise your documents. * Automatic arXiv, PubMed and CrossRef metadata retrieval If you show Referencer a PDF which has an arXiv ID or DOI code, Referencer will retrieve the metadata for this document over the internet. * Python plugin support Referencer can be extended using the versatile Python scripting language. * Localisation
