Abstract: A framework and the associated method, schema and design for processing digital data, whether random or not, through encoding and decoding losslessly and correctly for purposes including the purposes of encryption/decryption or compression/decompression or both. There is no assumption of the digital information to be processed before processing. An universal coder is invented and now pigeonhole meets blackhole.

Abstract: An embodiment of the present invention provides a system that enables a user to securely invoke a REST (Representational State Transfer) API (Application Programming Interface) at an application server. A client can establish a secure communication channel with an application server, and can send a request to the application server to invoke the REST API. The client can then receive a security token from an authentication system in response to authenticating the user with the authentication system. Next, the client can receive a nonce and a timestamp from the application server. The client can then determine a security token digest using the security token, the nonce, and the timestamp. Next, the client can resend the request to the application server to invoke the REST API with the security token digest. The application server can invoke the REST API if the security token digest is valid.

Abstract: Method for ‘Cool-Swap’, ‘Warm-Swap’ and ‘Hot-Swap’ of ‘Fixed’ ‘System’ hard disk(s) in and out of the computer and for re-cycling the computer between ‘diskly’ state to ‘diskless’ state by combining the following features in one way or the other: separating the power supply of the ‘Fixed’ ‘System’ hard disk(s) from the internal power supply that is supplying power to other components of the computer, in particular the motherboard; taking the operating system, capable of being taken to run as ramdisk-based operating system, in control of the computer to run as ramdisk-based operating system; putting the computer into different power management states; and issuing commands or instructions for logical disconnection and/or re-connection of hard disk(s).
