What is MySQL? MySQL, the most popular Open Source SQL database management system, is developed, distributed, and supported by Oracle Corporation. MySQL is a database management system. A database is a structured collection of data. It may be anything from a simple shopping list to a picture gallery or the vast amounts of information in a corporate network. To add, access, and process data stored in a computer database, you need a database management system such as MySQL Server. Since computers are very good at handling large amounts of data, database management systems play a central role in computing, as standalone utilities, or as parts of other applications. MySQL databases are relational. A relational database stores data in separate tables rather than putting all the data in one big storeroom. The database structures are organized into physical files optimized for speed. The logical model, with objects such as databases, tables, views, rows, and columns, offers a flexi...

Batteries from Electric Vehicles Should Be Recycled, Not Reused Recycling, rather than reuse, is likely to be the more attractive option for the 65-GWh of second-life batteries poised to enter the market in 2035 when the first generation of plug-in vehicles begins to retire, according to Lux Research. Reusing batteries from electric vehicles will deliver questionable returns due to reduced performance, limiting them to applications with less frequent and shallower depth of discharge cycles. An oversized 11.2-kWh residential system based on reusing batteries will cost just over $4,600, compared with nearly $6,000 for a new 7-kWh system. However, reduced round-trip efficiency and cycle life make residential units and other daily cycling applications a poor fit compared to some other applications. “With present technology, recycling old batteries for new materials is a more economical option for creating the most value from existing materials,” says Christopher Robinson, Lux Research...

Augmented Reality (AR) Augmented reality is a live direct or indirect view of a physical, real-world environment whose elements are "augmented" by computer-generated or extracted real-world sensory input such as sound, video, graphics, haptics or GPS data. The term ‘augmented reality‘ or AR when used in the context of computer technology refers to what we perceive through our senses (usually sight) enhanced through the use of computer-generated sensory input such as sound, video, graphics and GPS data. Simply put, AR makes available more information for us users by combining computer data to what we see in real life. Using the camera on your phone, you can point it somewhere ‘live’ to get an information overlay of where you can find the nearest cafes or dining places, for example:-  Smartphones being portable serve as a good platform for AR to work. You can just whip out your phone to get the latest and relevant info for what you are searching for – information whi...
