SafeSlinger
Face-to-face (or over-the-phone) meetings give you the opportunity to exchange keys with others, so e-mails, texts, and other communications can be trusted as to the source. This all happens transparently, as the app “slings” your key to one or more contacts, and vice versa, enabling trusted introductions to others, for example. Free (Android, iOS).

Answers
1. (c) HDFS stands for the Hadoop Distributed File System, the storage mechanism that underlies the processing functions of MapReduce. 2. (b) Favored by Rails gurus, DRY refers to the “don’t repeat yourself” software development pattern, which mandates having a single unambiguous, authoritative representation within a system. The goal is to avoid making sweeping changes throughout a distributed system whenever any one element changes. 3. (a) Address space layout randomization, or ASLR, is a security technique that randomly rearranges address spaces in memory, including positions of the stack, heap, libraries, and the base of the executable, so that attackers cannot exploit the function in memory (protects against buffer overflow attacks).Photography byClem Onojeghuo,Unsplash
