Boolean operations utilizing DNA as a platform for biocomputing have become a promising tool for next-generation bio-molecular computers. In the whole process of any binary data transmission, bit errors are unavoidable and commonly occur. Cascades of exclusive-OR (XOR) operations show the great potential to evaluate these errors by introducing a parity generator (pG) and a parity checker (pC). Herein, we constructed a DNA hybrid architecture platform employing a chemosensing ensemble of mercury-mediated DNA–Au/Ag nanoclusters (M–Au/Ag NCs) to operate unconventional pG/pC for “error detection”. Taking advantage of pG/pC, the transmitted and received data is converted to secure information using a binary to gray code encoder. To the best of our knowledge, this is the first molecular gray code encoder for biocomputing, which discovers an exciting avenue to protect information security through sophisticated logic circuits.

The article discloses a method aimed at improving the performance of the receiving side of a file transfer environment particularly in terms of transferring files with bigger size. Cited are the benefits of such improvement to file copy scenarios and to all other processes running on a system. According to the article, such method involves a mechanism to efficiently handle the socket receive buffer and the manner in which it is written to disk without providing a copy to user space.

The article focuses on a method to improve domain name system (DNS) server performance by maintaining a cache in the kernel space. The DNS cache, which stores the successful name resolution for a certain period of time, is being maintained in user space as the DNS servers are user space program. The method is said to be capable of allowing a client to experience faster name resolution. It points out the impossibility of caching all possible DNS responses but only the most frequent ones due to resource constraints.
