Frost - A backup program that does deduplication, compression, encryption

  •        19

A backup program that does deduplication, compression, encryption. It's based on the ideas of Syncany, but reimplemented in C++, using state of art compression (BSC library), no dependency on anything except libcrypto. It provides a console mode that has been tested on both Linux and MacOSX. It allows saving backups to a remote server that's considered hostile, with no modification to the remote server software required. Because of deduplication, space saving is considerable between backup and in a backup itself. Then even more data is preserved with compression (using either zLib or BSC library), and compressed data is encrypted in local files (or remote files if you mounted then beforehand).

Borg - Deduplicating archiver with compression and authenticated encryption

  •    C

BorgBackup (short: Borg) is a deduplicating backup program. Optionally, it supports compression and authenticated encryption. The main goal of Borg is to provide an efficient and secure way to backup data. The data deduplication technique used makes Borg suitable for daily backups since only changes are stored. The authenticated encryption technique makes it suitable for backups to not fully trusted targets.

EASTL - EASTL stands for Electronic Arts Standard Template Library

  •    C++

EASTL stands for Electronic Arts Standard Template Library. It is a C++ template library of containers, algorithms, and iterators useful for runtime and tool development across multiple platforms. It is a fairly extensive and robust implementation of such a library and has an emphasis on high performance above all other considerations. If you are familiar with the C++ STL or have worked with other templated container/algorithm libraries, you probably don't need to read this. If you have no familiarity with C++ templates at all, then you probably will need more than this document to get you up to speed. In this case, you need to understand that templates, when used properly, are powerful vehicles for the ease of creation of optimized C++ code. A description of C++ templates is outside the scope of this documentation, but there is plenty of such documentation on the Internet.

Akumuli is a time-series database for modern hardware. It can be used to capture, store and process time-series data in real-time. The word "akumuli" can be translated from Esperanto as "accumulate".

backup-adblockpluschrome - Adblock Plus extension for Google Chrome

  •    Javascript

This repository contains the platform-specific Adblock Plus source code for Chrome, Opera and Safari. It can be used to build Adblock Plus for these platforms, generic Adblock Plus code will be extracted from other repositories automatically (see dependencies file). This will create a build with a name in the form adblockpluschrome-1.2.3.nnnn.crx or adblockplussafari-1.2.3.nnnn.safariextz. Note that you don't need an existing signing key for Chrome or Opera, a new key will be created automatically if the file doesn't exist. Safari on the other hand always requires a valid developer certificate, you need to get one in the Apple Developer Center first. adblockplussafari.pem should contain the private key for your developer certificate, the developer certificate itself as well as all the certificates it was signed with (Apple's root certificate and intermediate certificates) in PEM format - in that order.

CyberChef - The Cyber Swiss Army Knife - a web app for encryption, encoding, compression and data analysis

  •    Javascript

CyberChef is a simple, intuitive web app for carrying out all manner of "cyber" operations within a web browser. These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more. The tool is designed to enable both technical and non-technical analysts to manipulate data in complex ways without having to deal with complex tools or algorithms. It was conceived, designed, built and incrementally improved by an analyst in their 10% innovation time over several years.

Sophus - C++ implementation of Lie Groups using Eigen.

  •    C++

This is a c++ implementation of Lie groups commonly used for 2d and 3d geometric problems (i.e. for Computer Vision or Robotics applications). Among others, this package includes the special orthogonal groups SO(2) and SO(3) to present rotations in 2d and 3d as well as the special Euclidean group SE(2) and SE(3) to represent rigid body transformations (i.e. rotations and translations) in 2d and 3d. Sophus compiles with clang and gcc on Linux and OS X as well as msvc on Windows. The specific compiler and operating system versions which are supported are the ones which are used in the Continuous Integration (CI): See TravisCI and AppVeyor for details.

cmake-init - Template for reliable, cross-platform C++ project setup using cmake.

  •    C++

cmake-init is a sophisticated copy & paste template for modern C and C++ projects. The main goals include support of all use cases around software development (programming, testing, Q&A, deployment, documentation) while being modular, flexible, and idomatic. cmake-init is therefore a collection of cmake best-practices. The file ADAPT.md contains a task checklist for new projects. More generally, a new project should contain all core modules and, as needed, add the maintainer and development modules as required. cmake-init does not impose modularity rules for the cmake targets.

glbinding - A C++ binding for the OpenGL API, generated using the gl.xml specification.

  •    C++

glbinding is a cross-platform C++ binding for the OpenGL API. glbinding leverages modern C++11 features like enum classes, lambdas, and variadic templates, instead of relying on macros; all OpenGL symbols are real functions and variables. It provides type-safe parameters, per feature API header, lazy function resolution, multi-context and multi-thread support, global and local function callbacks, meta information about the generated OpenGL binding and the OpenGL runtime, as well as tools and examples for quick-starting your projects. Based on the OpenGL API specification (gl.xml) glbinding is generated using python scripts and templates that can be easily adapted to fit custom needs.

Would you like to build/train a model using Keras/Python? And would you like run the prediction (forward pass) on your model in C++ without linking your application against TensorFlow? Then frugally-deep is exactly for you. Layer types typically used in image recognition/generation are supported, making many popular model architectures possible (see Performance section).

globjects - C++ library strictly wrapping OpenGL objects.

  •    C++

globjects is a cross-platform C++ wrapper for OpenGL API objects. globjects provides object-oriented interfaces to the OpenGL API (3.0 and higher). It reduces the amount of OpenGL code required for rendering and facilitates coherent OpenGL use by means of an additional abstraction layer to glbinding and GLM. Common rendering tasks and processes are automated and missing features of specific OpenGL drivers are partially simulated or even emulated at run-time.
