utf8

•    Javascript

---

utf8.js is a well-tested UTF-8 encoder/decoder written in JavaScript. Unlike many other JavaScript solutions, it is designed to be a proper UTF-8 encoder/decoder: it can encode/decode any scalar Unicode code point values, as per the Encoding Standard. Here’s an online demo.A string representing the semantic version number.

bincode - A binary encoder / decoder implementation in Rust.

•    Rust

---

A compact encoder / decoder pair that uses a binary zero-fluff encoding scheme. The size of the encoded object will be the same or smaller than the size that the object takes up in memory in a running Rust program. In addition to exposing two simple functions (one that encodes to Vec<u8>, and one that decodes from &[u8]), binary-encode exposes a Reader/Writer API that makes it work perfectly with other stream-based apis such as rust files, network streams, and the flate2-rs compression library.

PMJSON - Pure Swift JSON encoding/decoding library

•    Swift

---

PMJSON provides a pure-Swift strongly-typed JSON encoder/decoder as well as a set of convenience methods for converting to/from Foundation objects and for decoding JSON structures. The entire JSON encoder/decoder can be used without Foundation, by removing the files ObjectiveC.swift and DecimalNumber.swift from the project. The only dependency the rest of the project has is on Darwin, for strtod() and strtoll(). The file ObjectiveC.swift adds convenience methods for translating between JSON values and Foundation objects as well as decoding from a Data, and DecimalNumber.swift adds convenience accessors for converting values into NSDecimalNumber.

Simple Binary Encoding - Simple Binary Encoding (SBE) - High Performance Message Codec

•    Java

---

SBE is an OSI layer 6 presentation for encoding and decoding binary application messages for low-latency financial applications. This repository contains the reference implementations in Java, C++, Golang, and C#. The Java and C++ SBE implementations are designed with work very efficiently with the Aeron messaging system for low-latency and high-throughput communications. The Java SBE implementation has a dependency on Agrona for its buffer implementations.

RLSeq2Seq - Deep Reinforcement Learning For Sequence to Sequence Models

•    Python

---

NOTE: THE CODE IS UNDER DEVELOPMENT, PLEASE ALWAYS PULL THE LATEST VERSION FROM HERE. In recent years, sequence-to-sequence (seq2seq) models are used in a variety of tasks from machine translation, headline generation, text summarization, speech to text, to image caption generation. The underlying framework of all these models are usually a deep neural network which contains an encoder and decoder. The encoder processes the input data and a decoder receives the output of the encoder and generates the final output. Although simply using an encoder/decoder model would, most of the time, produce better result than traditional methods on the above-mentioned tasks, researchers proposed additional improvements over these sequence to sequence models, like using an attention-based model over the input, pointer-generation models, and self-attention models. However, all these seq2seq models suffer from two common problems: 1) exposure bias and 2) inconsistency between train/test measurement. Recently a completely fresh point of view emerged in solving these two problems in seq2seq models by using methods in Reinforcement Learning (RL). In these new researches, we try to look at the seq2seq problems from the RL point of view and we try to come up with a formulation that could combine the power of RL methods in decision-making and sequence to sequence models in remembering long memories. In this paper, we will summarize some of the most recent frameworks that combines concepts from RL world to the deep neural network area and explain how these two areas could benefit from each other in solving complex seq2seq tasks. In the end, we will provide insights on some of the problems of the current existing models and how we can improve them with better RL models. We also provide the source code for implementing most of the models that will be discussed in this paper on the complex task of abstractive text summarization.

toml-rs - A TOML encoding/decoding library for Rust

•    Rust

---

A TOML decoder and encoder for Rust. This library is currently compliant with the v0.4.0 version of TOML. This library will also likely continue to stay up to date with the TOML specification as changes happen. This crate also supports serialization/deserialization through the serde crate on crates.io. Currently the older rustc-serialize crate is not supported in the 0.3+ series of the toml crate, but 0.2 can be used for that support.

For all your async streaming MP3 encoding/decoding needs, there's node-lame! This module hooks into libmp3lame, the library that the lame command uses, to provide Encoder and Decoder streams to NodeJS.node-lame comes bundled with its own copy of libmp3lame and libmpg123, so there's no need to have them installed on your system.

json - A robust JSON decoder/encoder with support for schema validation.

•    PHP

---

A robust wrapper for json_encode()/json_decode() that normalizes their behavior across PHP versions, throws meaningful exceptions and supports schema validation by default. Note: This does not work if you use the $schema property to set the schema (see next section). If that property is set, the schema is always used for validation during encoding and decoding.
