go-erasure - Erasure coding (Reed–Solomon coding) in Go

  •        11

Go bindings for erasure coding (Reed-Solomon coding). Erasure coding is similar to RAID based parity encoding, but is more generalized and powerful. When defining an erasure code, you specify a k and m variable. m is the number of shards you wish to encode and k is the number shards it takes to recreate your original data. Hence k must be less than m and usually not equal (as that would be a pointless encoding). The real magic with erasure coding is that fact that ANY k of the m shards can recreate the original data. For example, a erasure coding scheme of k=8 and m=12 means any four of the encoded shards can be lost while the original data can still be constructed from the valid remaining eight shards.

Sia - Your decentralized private cloud

  •    Go

Sia is a new decentralized cloud storage platform that radically alters the landscape of cloud storage. By leveraging smart contracts, client-side encryption, and sophisticated redundancy (via Reed-Solomon codes), Sia allows users to safely store their data with hosts that they do not know or trust. The result is a cloud storage marketplace where hosts compete to offer the best service at the lowest price. And since there is no barrier to entry for hosts, anyone with spare storage capacity can join the network and start making money.

enumeratum - A type-safe, reflection-free, powerful enumeration implementation for Scala with exhaustive pattern match warnings and helpful integrations

  •    Scala

Enumeratum is a type-safe and powerful enumeration implementation for Scala that offers exhaustive pattern match warnings, integrations with popular Scala libraries, and idiomatic usage that won't break your IDE. It aims to be similar enough to Scala's built in Enumeration to be easy-to-use and understand while offering more flexibility, type-safety (see this blog post describing erasure on Scala's Enumeration), and richer enum values without having to maintain your own collection of values. Enumeratum is published for Scala 2.10.x, 2.11.x, and 2.12.x as well as ScalaJS.

dyno - Runtime polymorphism done right

  •    C++

At this point, this library is experimental and it is a pure curiosity. No stability of interface or quality of implementation is guaranteed. Use at your own risks. Dyno solves the problem of runtime polymorphism better than vanilla C++ does. It provides a way to define interfaces that can be fulfilled non-intrusively, and it provides a fully customizable way of storing polymorphic objects and dispaching to virtual methods. It does not require inheritance, heap allocation or leaving the comfortable world of value semantics, and it can do so while outperforming vanilla C++.

BaconQrCode is a port of QR code portion of the ZXing library. It currently only features the encoder part, but could later receive the decoder part as well. As the Reed Solomon codec implementation of the ZXing library performs quite slow in PHP, it was exchanged with the implementation by Phil Karn.

UDPspeeder - A Tunnel which Improves your Network Quality on a High-latency Lossy Link by using Forward Error Correction,for All Traffics(TCP/UDP/ICMP)

  •    C++

A Tunnel which Improves your Network Quality on a High-latency Lossy Link by using Forward Error Correction. Assume your local network to your server is lossy. Just establish a VPN connection to your server with UDPspeeder + any UDP-based VPN, access your server via this VPN connection, then your connection quality will be significantly improved. With well-tuned parameters , you can easily reduce IP or UDP/ICMP packet-loss-rate to less than 0.01% . Besides reducing packet-loss-rate, UDPspeeder can also significantly improve your TCP latency and TCP single-thread download speed.

hat-trie - C++ implementation of a fast and memory efficient HAT-trie

  •    C++

Trie implementation based on the "HAT-trie: A Cache-conscious Trie-based Data Structure for Strings." (Askitis Nikolas and Sinha Ranjan, 2007) paper. For now, only the pure HAT-trie has been implemented, the hybrid version may arrive later. Details regarding the HAT-trie data structure can be found here. The library provides an efficient and compact way to store a set or a map of strings by compressing the common prefixes. It also allows to search for keys that match a prefix. Note though that the default parameters of the structure are geared toward optimizing exact searches, if you do a lot of prefix searches you may want to reduce the burst threshold through the burst_threshold method.
