Here is one review:



TITLE INFORMATION

NETIQUETTE IQ
A Comprehensive Guide to Improve, Enhance and Add Power to Your Email
Babicki, Paul CreateSpace (264 pp.) $18.95 paperback ISBN: 978-1481849524; September 14, 2013


BOOK REVIEW 

A revealing primer on the art of effective emails and other communications. 

Babicki, in his debut self-help guide, covers the many peculiarities of computerized messaging: How to shape an eye-catching subject line; how to troubleshoot error messages from a returned email; what the file-extension suffixes on attachments mean; what the email time stamp tells others about your personality (night owl vs. early riser); and how to craft a corporate email security policy. His advice on these sometimes-arcane topics is precise—“RTF format should only be used when it is certain that the recipient uses Outlook”—while also remaining intelligible to laypeople. The author also instructs readers on time-honored principles of proper English and clear expression. He delves with detailed lucidity into rules of grammar, punctuation and usage; prescribes the proper formatting of numbers and dates; and inveighs against the dangling participle. He also explores the tonal shadings of different kinds of salutations, crusades for concise and gracious style, warns against the gassy redundancy of such wordings as “final outcome” and “at an early time,” and appends a blacklist of “the most irritating phrases,” from “out of the box” to “team player.” Good writing grows from good thinking, so he instructs readers on the pitfalls of logical fallacies, from the ad hominem attack to the begged question, and on the distinctions between assumption, presumption and inference. Furthermore, since communication is the cornerstone of civilized life, he limns its legal and moral underpinnings in copyright and plagiarism strictures, codes of courteous Internet deportment and techniques for pacifying flame wars. (He recommends a “Zen” approach, for example, in replying to angry missives.) The result is a mashup of Strunk and White, Miss Manners, Aristotle and Microsoft Help, all laid out in a well-organized, very readable text sprinkled with amusing examples and phrased in the tart, aphoristic style of an exacting schoolmaster (“The better it sounds, the more it is trusted”). Overall, Babicki’s technical expertise and literary aplomb make this a fine manual for the everyday scribe.
A comprehensive, stimulating guide to getting the word out.

Rowhammer
Posted by: Margaret Rouse
Contributor(s): Madelyn Bacon
Rowhammer is a vulnerability in commodity dynamic random access memory (DRAM) chips that allows an attacker to exploit devices with DRAM memory by repeatedly accessing (hammering) a row of memory until it causes bit flips and transistors in adjacent rows of memory reverse their binary state: ones turn into zeros and vice versa.
The flaw, first reported in the paper "Flipping Bits in Memory Without Accessing Them: An Experimental Study of DRAM Disturbance Errors," detailed how, as DRAM processes continues to scale to smaller sizes, it becomes more difficult to prevent individual memory cells from interacting with neighboring cells.
The Rowhammer flaw allows memory manipulation to be used by malicious actors to extract data such as passwords from vulnerable systems. The flaw has been detected in DDR3 and DDR4 DRAM chips and, when combined with other attacks, can be used to access the contents of memory on systems using vulnerable chips. The Google Project Zero team published details of its proof of concept code for exploits of Rowhammer on x86-64 Linux machines, but they wrote that the exploit was likely not specific to Linux systems.
Rowhammer accomplishes this manipulation by forcing the repeated reading and recharging of a row of capacitors in a DRAM chip. The repeated reading and recharging of a row happens when an attacker uses the machine code instruction Cache Line Flush (CLFLUSH) to clear the cache, as shown in the 2014 research paper from Carnegie Mellon University and Intel Labs researchers. Caching limits prevent bit flipping from occurring normally, so the repeated CLFLUSH overloads the system. When the bit flipping happens too often and in capacitor rows too close together, neighboring capacitors begin to interact electrically, and this opens up the opportunity to exploit the Rowhammer flaw.
Researchers at Intel became aware of Rowhammer in 2012 and filed patent applications that were publically disclosed, but the vulnerability didn't garner much attention until 2014 when the research paper was published. DRAM chips are an important part of most electronic devices, including those that are essential to computers. As such, DRAM vulnerabilities like Rowhammer cannot be fixed with basic security software or operating system (OS) updates. Rowhammer continues to be used in new attacks.
