Magento is leading in the Ecommerce business and also makes appropriate updates regularly. The latest release of Magento where Magento 2.3.5 was released which was on 28th April 2020.  Every time the installation is not smooth but many times it causes issues during the installation of the new version and most of the users experience it . Don't worry, We have the solution for solving the issue in the installation of Magento 2. Console Log : [Error] InvalidArgumentException: Wrong file in m235\vendor\magento\framework\ Image\Adapter\Gd2.php:64 Steps : 1. Find validateURLScheme function in vendor\magento\framework\ Image\Adapter\Gd2.php file. at line 96. 2. Replace function with below code:      private function validateURLScheme(string $filename) : bool   {       $allowed_schemes = ['ftp', 'ftps', 'http', 'https'];       $url = parse_url($filename);       if ($url && isset($url['scheme']) && !in_array($url['scheme'], $al

Bitcoin | Cryptocurrency

Bitcoin is a decentralized digital currency proposed in 2008 in a paper authored by someone behind the Satoshi Nakamoto pseudonym . Since then, it has reached a level of adoption unrealized by decades of previously proposed digital currencies. Unlike most previous proposals, Bitcoin does not distribute digital monetary units to users. Instead, a public ledger (called the blockchain) maintains a list of every transaction made by all Bitcoin users since the deployment of the currency in January 2009 when it became fully functional.                                        Bitcoin network is an overlay network built upon peer-to-peer broadcasts which carries all information in the network. Through broadcasts, network achieves eventual consensus and information consistency. Generated transactions are continually propagated to neighbor nodes to induce updates, and the block which contains several confirmed transactions are also created and propagated to the entire network. There are a number

Internet Of Things (IOT)

The internet isn't just about computers anymore. Now all kinds of everyday objects can connect to the internet. Including cars, thermostats, sporting equipment, refrigerators and even shoes. This is known as the Internet of Things (IOT).    Now you may be wondering why would shoes need to connect to the internet. Well the shoes can collect data like how many steps you take which can be viewed from another internet connected device like a smart phone. All the metrics collected by the shoes can be analyzed to tell you how many calories you've burned, give you personalized fitness advice and much more.   But the Internet of Things is not limited to consumer products. There are city trash cans that send alerts when need to be emptied. Sensors on bridges that check for stress or damage to its structure. And many more examples extending to healthcare, manufacturing, and agriculture among others. Unfortunately there are also new security concerns. Example: If you have internet connect

Graphene And Flexible Electronics

        Graphene is a two dimensional form of carbon which is one atom thick layer of graphite.       It is around 100 times stronger than steel and has a conductivity which is much better than   copper.        High charge carrier mobility – 10,000 cm square/Vs.        It is the strongest and thinnest material known to exist.        Due to its electronic properties, it absorbs 2.3% of light that passes through it.       Signal flowing through the devices made of graphene can flow with speeds greater than the speed of light.        High thermal conductivity, chips with better dissipating heat can be made.      Antennas, transistors, batteries and touch screens become more efficient and flexible when created by using Graphene.      It has a modulation depth of 64% with GHz bandwidth whereas silicon has a modulation depth of 46%.                 Energy band diagram for Semiconductor and Graphene       In semiconductors, an electron bound to an atom can break free only if it gets enough
