IFTTH
Interapp automations are easy to accomplish with IFTTH (If This, Then That). Templated “recipes” that run in the background let you create powerful connections with one simple statement—if this, then that. Automate the process of having photos from your New Year’s Eve party uploaded to Facebook, for example. Free (Android, iOS).

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).

Top 10 Ranking of Devices Users Trust Most

Researchers in the College of Engineering at Carnegie Mellon University asked 2,000 US consumers to rank the 10 electronic devices that they trust most with their personal information. People have the most trust in their home phone systems, followed by their home security systems. Concerns about personal information being at risk are highest for laptop computers (54.3 percent), desktop computers (49.3 percent), and smartphones (48.2 percent). On average, users trust their personal devices just as much as their work devices.

         b. Parameter passing
         c. Register spillage protection
         d. The “return to sender” design pattern

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).
