Redis is an in-memory key-value store that can be used as a data structure server. It supports basic data structures like strings, lists, sets, sorted sets and hashes. Data can be persisted to disk using snapshots and append-only files with rewriting. It supports transactions using MULTI and EXEC commands and pipelining to improve performance. Publish/subscribe messaging and master-slave replication with consistent hashing are also features. Redis has client libraries for many languages and the Hiredis C library provides an easy to use API. Redis can be applied to use cases like caching, queues and more.

第一回MongoDBソースコードリーディング
This document discusses MongoDB's oplog and logging operations. It covers:
1. The createOplog function which creates the oplog as a capped collection in the local database.
2. The logOp function which logs operations to the oplog in BSON format with fields like timestamp, operation type, namespace, and operation object.
3. The _logOp and _logOpOld functions which handle actually writing to the oplog, with _logOpOld writing directly to the data file.
Compiler basics: lisp to assembly
This document outlines a project to compile a subset of Lisp to x86-64 assembly using Node.js without third-party libraries. It demonstrates the basic components of a compiler including parsing, generating an abstract syntax tree, and code generation. The goal is to compile simple Lisp expressions like (+ 3 (+ 1 2)) to assembly that computes the result. The document discusses parsing to an AST, generating assembly code, calling conventions, syscalls, and testing the generated code. It concludes with ideas for improvements like adding error handling and linking to libraries.
Extend Redis with Modules
Starting with v4, modules hold a promise for changing how Redis is used and developed for. Enabling custom data types and commands, Redis Modules build upon and extend the core functionality to handle any use case.

Redis clustering
This document provides instructions for installing Redis and configuring a Redis cluster in Linux. It explains how to download and compile Redis, create configuration files for 6 nodes using different ports and filenames, start each Redis server using its configuration file, and use the redis-cli command to create a cluster with 1 replica across the 6 nodes. Once created, information about node 1 can be viewed by connecting to it on port 7001 with redis-cli.
Redis modules 101
The document summarizes Redis Modules and provides an overview of how to build and use Redis Modules. Some key points:
- Redis Modules allow developers to extend Redis with new commands by dynamically loading libraries written in C/C++. This provides new functionality and integrates with existing Redis data types and commands.
- The Modules API provides both high-level and low-level interfaces. The high-level API is similar to Lua but slower, while the low-level API exposes specific Redis commands and data types for better performance.
- Building a simple module involves writing a command handler, validating arguments, making Redis calls, and returning a reply. Modules are initialized via an OnLoad function and new commands can

RESTinio is a header-only library for creating REST applications in c++. It helps to create http server that can handle requests asynchronously. And since v.0.3 it supports websockets.
Redis - N✮SQL Berlin
Redis is an open source key-value store that is fast, simple to use, and supports data structures like lists, sets, and sorted sets. It stores data in-memory for fast access but can also persist data to disk asynchronously. It uses a simple text-based protocol and can be used for caching, processing statistical data, and as a data store for transient but recoverable states. Redis works both as a single server or in a master-slave configuration for horizontal scaling and high availability.

OSMC 2014: Introduction into collectd | Florian Foster
Periodically measuring performance metrics of production systems allows administrators and developers to analyze system behavior during and after outages, quantify performance improvements, and detect trends and take proactive measures before problems arise. Performance metrics are also interesting for alerting, because they can be aggregated meaningfully, thereby basing an alert on a group of hosts rather than each host individually, for example.
This talk will give an introduction to collectd, an open-source tool to gather, process and store performance metrics. A sample setup which aggregates a couple of metrics and stores the aggregate in Graphite will be presented. Afterwards, we will show how the collectd-nagios utility can be used to define alerts in Icinga based on this data.

The rise of NoSQL databases and their simplicity has made corporates as well as end users have started to move towards NoSQL,However is it safe?.Does NoSQL mean we will not have to worry about Injection attacks. Yes We Do. This paper concentrates on exploiting NoSQL DB’s especially with its reach towards Mongodb,Couchdb and Redis and automating it using the NoSQL Exploitation Framework.
Work WIth Redis and Perl
This document discusses using Redis as a work queue for distributing tasks across worker processes. It provides an overview of Redis, describes how to implement a basic work queue using Redis lists, and shows various work queue patterns like synchronous and asynchronous producer-consumer models. It also covers options for scaling out queues and ensuring high availability and reliability. Code examples are provided using the Redis.pm Perl module.
Scaling php applications with redis
Redis is a NoSQL technology that rides a fine line between database and in-memory cache. Redis also offers "remote data structures", which gives it a significant advantage over other in-memory databases. This session will cover several PHP clients for Redis, and how to use them for caching, data modeling and generally improving application throughput.
