parallel-hashmap provides a family of header-only, very fast and memory-friendly hashmap and btree containers for C++11 and above.

It has the following characteristics:

• Drop-in replacement for std::unordered_map, std::unordered_set, std::map, and std::set with better performance.

• Requires C++11 compiler support and provides C++14 and C++17 APIs, including features like try_emplace.

• Highly efficent and faster than standard unordered containers, Boost implementations, or sparsepp alternatives.

• Memory-friendly: maintains low memory usage with a slight increase compared to sparsepp.

• Heterogeneous lookup support.

• Dump/load feature: for flat hash maps storing std::trivially_copyable data, the entire table can be dumped to disk and restored as a single array efficiently without hash computations. This is about 10 times faster than element-wise serialization but uses 10% to 60% extra disk space.

• Automatic support for boost::hash_value() and default hash functions for std::pair and std::tuple.

liburcu is a user-space Read-Copy-Update (RCU) data synchronisation library. It provides read-side access that scales linearly with the number of cores. liburcu-cds provides efficient data structures based on RCU and lock-free algorithms. These structures include hash tables, queues, stacks, and doubly-linked lists.

uthash implements a hash table and a few other basic data structures as C preprocessor macros. It aims to be minimalistic and efficient: it's around 1,000 lines of code which, being macros, inline automatically.

Unlike function calls with fixed prototypes, macros operate on untyped arguments. Thus, they are able to work with any type of structure and key. Any C structure can be stored in a hash table by adding UT_hash_handle to the structure and choosing one or more fields to act as the key.

MARISA is a static and space-efficient trie data structure C++ library.

tllist is a typed linked list C header file only library implemented using pre-processor macros. It supports primitive data types as well as aggregated ones such as structs, enums and unions.

Pimsync synchronizes your calendars and contacts between two storage locations. The most popular purpose is to synchronize a CalDAV or CardDAV server with a local folder or file.

Cadaver is a command-line client for WebDAV server operations. It supports a variety of WebDAV features and provides an interactive command-line environment with support for file manipulation on remote WebDAV servers.

Xandikos is a lightweight yet complete CardDAV/CalDAV server that backs onto a Git repository.

Features:

• Easy to set up

• Share calendars (events, todo items, journal entries) via CalDAV and contacts (vCard) via CardDAV

• Automatically keep history and back up changes in Git

• Supports synchronization extensions for CalDAV/CardDAV for quick and efficient syncing

• Automatically keep history and back up

• Works with all tested CalDAV and CardDAV clients

Radicale is a CalDAV and CardDAV server for UNIX-like platforms. Calendars and address books are available for both local and remote access, possibly limited through authentication policies. They can be viewed and edited by calendar and contact clients on mobile phones or computers.

Radicale intentionally does not fully comply with the CalDAV and CardDAV RFCs. Instead, it supports the CalDAV and CardDAV implementations of popular clients.

Vdirsyncer synchronizes your calendars and addressbooks between two storage locations. The most popular purpose is to synchronize a CalDAV or CardDAV server with a local folder or file. The local data can then be accessed via a variety of programs, none of which have to know or worry about syncing to a server.

GDBM is a library for manipulating hashed databases. It is used to store key/value pairs in a file in a manner similar to the Unix dbm library and provides interfaces to the traditional file format.

Berkeley DB is an embeddable database allowing developers the choice of SQL, Key/Value, XML/XQuery or Java Object storage for their data model.

Ncdc is a client for the Direct Connect peer-to-peer protocol implemented using ncurses. It is known for its smaller footprint and ease of use.

This package provides a number of utilities which are mostly for use in installation scripts of Debian packages. The programs included are add-shell, installkernel, ischroot, remove-shell, run-parts, savelog, tempfile, and which.

The Pureos distribution signs its packages. This package contains the archive keys used for that.

This package provides the low-level infrastructure for handling the installation and removal of Debian software packages.

The Pardus distribution signs its packages. This package contains the archive keys used for that.

The Ubuntu project digitally signs its Release files. This package contains the archive keys used for that.

apt-mirror is a small tool that provides the ability to selectively mirror APT sources, including GNU/Linux distributions such as Debian and Trisquel.

The Kali distribution signs its packages. This package contains the archive keys used for that.

This package only provides the bts script from the Debian devscripts archive. It's useful for Guix Developers that interact with GNU's debbugs server.

Debootstrap is used to create a Debian base system from scratch, without requiring the availability of dpkg or apt. It does this by downloading .deb files from a mirror site, and carefully unpacking them into a directory which can eventually be chrooted into.
