Utkarsh - The Contragravity

Horror fans know the consequences of an encounter with the evil doll Annabelle – users should similarly beware of the same-named ransomware, which possesses a bag of evil tricks to wreak havoc on an infected computer. Discovered by security researcher Bart, Annabelle Ransomware includes everything but the kitchen sink when it comes to screwing up a computer. This includes terminating numerous security programs, disabling Windows Defender, turning off the firewall, encrypting your files, trying to spread through USB drives, making it so you can't run a variety of programs, and then to sweeten the pot, it overwrites the master boot record of the infected computer with a silly boot loader. Thankfully,  MalwareHunterTeam was able to extract the source code from the obfuscated executable so that we can get a better glimpse as to what this program is doing. When first run, Annabelle will configure itself to start automatically when you login to Windows  terminating a variety...

Imagine a future where every one of the billions of light bulbs in use today is a wireless hotspot delivering connectivity at speeds that can only be dreamed of with Wi-Fi. That's the goal of the man who invented such a technology, and this week Li-Fi took a step out of the domain of science fiction and into the realm of the real when it was shown to deliver speeds 100 times faster than current Wi-Fi technology in actual tests. Lifi internet is similar to Wi-fi. It is a wireless, bidirectional technology founded by Professor Harald Haas of  University of Edinburgh. Li-fi stands for Light fidelity which takes light from light-emitting diodes (LEDs) as a path to deliver networked, mobile, high-speed communication. Lifi is a wireless technology using LED lights to transmit data through network. Scientists have receive a speed of 224 gigabits per second in laboratories by using this technology and the expected speed in the in the outside world could be 1giga-byte (1GB) per seco...

MongoDB is changing the Business of Big Data Modern data is vast, unstructured, and at times unwieldy. It’s big and complicated, and we have big expectations for what it can do—and trying to store, process, and analyze all of it has led to the development of NoSQL databases. These document-based databases eschew the table-based structure of relational databases and let us group data more logically.                                         The leading NoSQL database, MongoDB, has come out ahead in the field for a few reasons. It is an open-source and cross-platform compatible data model. It also has some impressive built-in features that make it an excellent choice for businesses that need fast, flexible access to their data, whether it’s to make real-time, on-the-fly decisions, or to create tailored, data-driven experiences for users. It is also compatible with .NET, Java ...
