Subnet Calculator - IPv4/IPv6 - TunnelsUP Example Inputs IPv4 IPv6 Amazon Relational Database Service (RDS) Amazon RDS gives you online access to the capabilities of a MySQL, Oracle, Microsoft SQL Server, PostgreSQL, or Amazon Aurora relational database management system. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period and enabling point-in-time recovery. You benefit from the flexibility of being able to scale the compute resources or storage capacity associated with your Database Instance (DB Instance) via a single API call. Database Instances using Amazon RDS's MySQL, Oracle, SQL Server, and PostgreSQL engines can be provisioned with General Purpose (SSD) Storage, Provisioned IOPS (SSD) Storage, or Magnetic Storage.

There certainly is no shortage of solutions for this problem domain. Many tools exist that offer the ability to discover, save, organize, search, and retrieve information.
Managing Energy Costs in Grocery Stores Although the actions described in this section require more extensive implementation, they can dramatically increase the efficiency of your store. Ask your local utility for more information about initiating such projects. Optimize Refrigeration The optimization of refrigeration systems can reduce energy use by 24 percent relative to standard practice. Domain Name System The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates domain names, which can be easily memorized by humans, to the numerical IP addresses needed for the purpose of computer services and devices worldwide. The Domain Name System is an essential component of the functionality of most Internet services because it is the Internet's primary directory service. The Domain Name System distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain.
Running Hadoop On Ubuntu Linux (Single-Node Cluster) @ Michael G. Noll In this tutorial I will describe the required steps for setting up a pseudo-distributed, single-node Hadoop cluster backed by the Hadoop Distributed File System, running on Ubuntu Linux. Hadoop is a framework written in Java for running applications on large clusters of commodity hardware and incorporates features similar to those of the Google File System (GFS) and of the MapReduce computing paradigm. Hadoop’s HDFS is a highly fault-tolerant distributed file system and, like Hadoop in general, designed to be deployed on low-cost hardware.
The Five Best Tools for Creating Videos Without Installing Software Over the years I've published some lists and reviews of free tools for creating videos online. Quite a few of those tools have been for creating simple videos that are really just automated, audio slideshows. See Animoto for an example of this. HAZARDOUS AREAS, ELECTRICAL EQUIPMENT, HAZARDOUS AREA ZONES, ATEX - HAZARDOUS AREA ELECTRICAL This glossary is offered as a guide to some of the terminology associated with hazardous areas and explosion prevention.

Packet switching Packet switching is a digital networking communications method that groups all transmitted data – regardless of content, type, or structure – into suitably sized blocks, called packets. Overview An animation demonstrating data packet switching across a network (Click on the image to load the animation) Vampire bat-inspired drone can fly and crawl Robot drones that can both fly and move about on land would vastly improve their usefulness by increasing the areas in which they could operate. Adding wheels of sufficient size to handle most terrains, however, would adversely increase both the weight and size of such a drone. Researchers at the Swiss Federal Institute of Technology in Lausanne (EPFL), building on their earlier developments, have created a drone that uses wings incorporating movable tips, allowing it to both walk and fly. The DALER (Deployable Air-Land Exploration Robot) drone was actually inspired by the vampire bat that uses the tips of its wings like legs when moving around on the ground. Similarly, the DALER has wings that can be used as both wings and legs (whegs).
