Presentation on iDoctum interactive educational software.
Description on the different available softwares.
Developed by education professionals.
Award winning content.
This document lists the top 10 educational apps for kids, including Forest Home, Motion Math, Toontastic, BrainPOP Jr, Daniel Tiger's Stop, ChoreMonster, Simple Machines, Slice Fractions, Crayola ColorStudio HD, and Toca Kitchen 2. It also provides contact information for Redbytes Software, the developer located in Pune, Maharashtra, India.
This document provides an overview and introduction to NoSQL databases. It discusses key-value stores like Dynamo and BigTable, which are distributed, scalable databases that sacrifice complex queries for availability and performance. It also explains column-oriented databases like Cassandra that scale to massive workloads. The document compares the CAP theorem and consistency models of these databases and provides examples of their architectures, data models, and operations.
NoSQL databases are currently used in several applications scenarios in contrast to Relations Databases. Several type of Databases there exist. In this presentation we compare Key Value, Column Oriented, Document Oriented and Graph Databases. Using a simple case study there are evaluated pros and cons of the NoSQL databases taken into account.
NoSQL databases get a lot of press coverage, but there seems to be a lot of confusion surrounding them, as in which situations they work better than a Relational Database, and how to choose one over another. This talk will give an overview of the NoSQL landscape and a classification for the different architectural categories, clarifying the base concepts and the terminology, and will provide a comparison of the features, the strengths and the drawbacks of the most popular projects (CouchDB, MongoDB, Riak, Redis, Membase, Neo4j, Cassandra, HBase, Hypertable).

4G networks were developed to address the limitations of 3G networks in supporting high-capacity multimedia services and applications with lower costs. 4G uses an all-IP based Evolved Packet Core network and advanced radio technologies like OFDM, multiple antennas, and link adaptation to provide seamless high-speed wireless broadband connectivity and end-to-end quality of service. Key improvements include an evolved packet core, all-IP networking, seamless handovers between networks, and the end of circuit-switched voice calls.
This document provides an overview of Bacula, an open source network backup solution. It describes the main Bacula components including the Bacula Director, Console, File, Storage, Catalog, and Monitor services. It also discusses how Bacula allows for centralized backup/restore, scheduling, job prioritization, security features, restoration capabilities, storage device support, operating system support, and graphical user interfaces. The document concludes by announcing $4.5 million in funding for Bacula Systems to deliver enterprise-grade open source backup and restoration technologies to large data centers.
This document discusses CUBRID, an open source relational database management system (RDBMS). It provides information on the following:
- CUBRID was launched globally in 2008 and is optimized for web services and applications with high traffic. New features are developed in Romania.
- CUBRID uses a 3-tier architecture for high performance and scalability with various interfaces like ODBC, JDBC, PHP and tools for easy management.
- CUBRID provides high availability with automatic node failure detection and failover between master/slave brokers and database servers.
This document discusses three ways to configure Linux bonding in the kernel: 1) Using modprobe and alias commands, 2) Using sysfs directly by writing to bonding_masters and mode files, and 3) Adding slaves to an interface using sysfs without ifenslave. It notes the benefits of the sysfs method are handling multiple interfaces, reconfiguring without reboot, and avoiding problems with modprobe.
UDPCast is software that uses multicast over UDP to copy the contents of a computer's hard drive (seed host) to other computers on a network. It allows administrators to easily install and maintain the same software and operating system configuration on multiple computers, such as in a school computer lab. The imaging process involves preparing the hosts, installing software on the seed host, and using sender and receiver processes to transfer the contents over the network from the seed host to the other hosts using multicast UDP packets.
Org-Mode is an Emacs mode for note taking, task management, and plain text organization. It allows you to create documents with hierarchical structure, tags, timestamps, and status keywords. The presentation demonstrated Org-Mode and provided instructions for installing and configuring it, with additional resources for learning more.
