The document provides an overview of Redis, including:
1) Redis is an in-memory key-value store that allows users to store common data types like strings, lists, hashes and sets as values associated with a key.
2) Redis is free, fast, easy to install, and scales well as more data is inserted or operations are performed.
3) Redis can be used for caching, queues, analytics, and publish-subscribe systems to build applications that respond quickly even under heavy loads.
Redis for .NET Developers
Redis is an open-source, in-memory data structure store that allows for atomic operations on data structures like strings, hashes, lists, sets, sorted sets, and bitmaps. It supports common operations like push, pop, and get and can be used as a cache, for session storage, or to compute statistics. StackExchange uses Redis with two servers each with 96GB RAM handling over 60k requests per second on average.
A Developer Overview of Redis
Redis is an open-source, in-memory data structure store that can be used as a cache or database. It supports common data structures like strings, hashes, lists, sets and sorted sets.

Building and Scaling Node.js Applications
A introduction to web frameworks built on node. A discussion about scaling up and out your single server.
Webinar: Enabling Microservices with Containers, Orchestration, and MongoDB
Want to try out MongoDB on your laptop? Execute a single command and you have a lightweight, self-contained sandbox; another command removes all trace when you're done. Need an identical copy of your application stack in multiple environments? Build your own container image and then your entire development, test, operations, and support teams can launch an identical clone environment.
Containers are revolutionizing the entire software lifecycle: from the earliest technical experiments and proofs of concept through development, test, deployment, and support. Orchestration tools manage how multiple containers are created, upgraded and made highly available. Orchestration also controls how containers are connected to build sophisticated applications from multiple, microservice containers.
This webinar introduces the concepts behind containers and orchestration, then explains the available technologies and how to use them with MongoDB. Finally, you will see a demonstration of exactly how to create a MongoDB replica set on Docker and Kubernetes within the Google Cloud.

Hedis - GET HBase via Redis
Hedis stands for "Hyper Redis". It can retrieve data from **ANY** database directly and stores to itself.
Introduction to Redis
Redis is an open source, in-memory data structure store that can be used as a database, cache, or message broker. It supports data structures like strings, hashes, lists, sets, sorted sets with ranges and pagination. Redis provides high performance due to its in-memory storage and support for different persistence options like snapshots and append-only files. It uses client/server architecture and supports master-slave replication, partitioning, and failover. Redis is useful for caching, queues, and other transient or non-critical data.
Realtime Search Infrastructure at Craigslist (OpenWest 2014)
A brief history of search infrastructure at craigslist with an emphasis on our recent transition to using realtime (RT) indexing in Sphinx.
A simple introduction to redis
Redis is an open source, advanced key-value store that can be used as a data structure server since it supports strings, hashes, lists, sets and sorted sets. It is written in C, works on most POSIX systems, and can be accessed from many programming languages. Redis provides options for data persistence like snapshots and write-ahead logging, and can be replicated for scalability and high availability. It supports master-slave replication, sentinel-based master detection, and sharding via Redis clusters. Redis has been widely adopted by many companies and is used in applications like microblogging services.
MongoDB .local Bengaluru 2019: New Encryption Capabilities in MongoDB 4.2: A ...
New encryption capabilities in MongoDB 4.2 provide client-side field-level encryption that protects sensitive data. The encryption is performed by the client drivers using modern cryptography, keeping encrypted fields opaque to the database server and operators. This allows individual fields to be encrypted per document with customer-managed keys. The presentation provides a history of database security methods and covers the new encryption in terms of design, cryptography used, and developer experience. A code example demonstrates how to configure and use the new encryption capabilities.
10gen MongoDB Video Presentation at WebGeek DevCup
MongoDB is a document-oriented, horizontally scalable database. It uses dynamic schemas and stores data as JSON-like documents with optional schemas. MongoDB can be scaled out across multiple servers for high availability and large data volumes. Key features include replication, sharding, index types, atomic operations, embedded documents, and MapReduce.
Password hashing, salting, bycrpt
The document provides recommendations for securely storing user passwords. It recommends using bcrypt or PBKDF2 hashing with per-user salting to hash passwords before storing in a database. Bcrypt and PBKDF2 are slower algorithms that help protect against brute force and rainbow table attacks. The document also recommends storing the salt in a separate column to prevent attackers from cracking multiple passwords at once if the database is breached.
Redis introduction
Redis is a key-value store that can be used as a database, cache, or message broker. It supports string, hash, list, set and sorted set data structures. Redis is written in C and works on most POSIX systems. It is single-threaded but can scale horizontally by running multiple Redis instances. Redis can persist data to disk and support master-slave replication. It can be scaled out using sentinel for automatic failover, Twemproxy for data sharding, or Redis Cluster for sharding with automatic failover.
Redis begins
Redis is an open source, advanced key-value store. It supports data structures like lists, sets, sorted sets, and hashes. Redis can persist data on disk using Redis Database files or append-only files. Redis supports master-slave replication where slaves can be promoted to masters in case of failures using Redis Sentinel. The main thing to note is that Redis is single-threaded, so long operations can block the server.
2020-02-20 - HashiTalks 2020 - HashiCorp Vault configuration as code via Hash...
This document discusses using Terraform to configure Vault infrastructure as code. It begins with an overview of Vault and Terraform. It then covers important considerations for deploying Vault like authentication methods, policies, secret engines, and rotating secrets. The document shares examples of using Terraform resources to configure LDAP, AWS IAM, database credentials, and rotating secrets in Vault. It finds that some values added to Vault via Terraform are not always readable and recommends ways to continuously learn, share knowledge, and improve practices for infrastructure as code with Vault.
Redis and it's data types
Provides an overview of Redis which is a Key Value NoSQL database and the different data types it supports. Also shows how to use Redis Client API from node.
Proper passwordhashing
The document discusses proper password hashing methods for securely storing passwords. It begins by stating that most websites currently do not properly store passwords, either in plaintext or with a single hash without salt. This is irresponsible. The document then discusses proper hashing methods that should be used, including adding salt, using key derivation functions like PBKDF2, ARC4PBKDF2, and bcrypt. PBKDF2 works by repeatedly hashing the password with a salt, while ARC4PBKDF2 additionally encrypts the password and hashes with an evolving ARC4 stream for added complexity. Bcrypt is also an adaptive function that works similarly to PBKDF2 but in a more complicated way. The document

Node.js vs Play Framework
Video: https://www.youtube.com/watch?v=b6yLwvNSDck
Here's the showdown you've been waiting for: Node.js vs Play Framework. Both are popular open source web frameworks that are built for developer productivity, asynchronous I/O, and the real time web. But which one is easier to learn, test, deploy, debug, and scale? Should you pick Javascript or Scala? The Google v8 engine or the JVM? NPM or Ivy? Grunt or SBT?

Scimore CommunityDays 2011
YesSQL allows for SQL queries on NoSQL databases, combining the best of both worlds. It summarizes the evolution of databases from small single node databases 15 years ago to today's large distributed databases with massive loads. ScimoreDB is a distributed SQL database that scales horizontally on commodity hardware while maintaining ACID transactions, consistency and a SQL interface. It partitions and distributes data across multiple nodes and groups them for high availability and scalability.

Artificial Intelligence for XMLDevelopment
In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

Introduction of Cybersecurity with OSS at Code Europe 2024
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.
