Meltdown, Spectre chip flaws raise questions about hardware security

by Alyssa Newcomb nbcnews.com

Flaws in computer chips are unusual, which is what makes Meltdown and Spectre, the stunning set of security vulnerabilities released on Wednesday, such a massive problem for users around the world.

Virtually every modern computing device is affected by the flaws, leaving technology companies scrambling to release patches to mitigate the threat, which could otherwise leave sensitive information exposed to hackers.

"It's a very big deal and the only thing people can do is wait for patches on systems and apply them," said Shuman Ghosemajumder, chief technology officer at Shape Security.

The security flaws are located in each computer's brain, known as the central processing unit or CPU. Processors are able to predict what tasks they will need to execute. This is known as "speculative execution" and allows the processor to simultaneously access multiple places of memory.

While this data is supposed to be protected, researchers found some instances when the processor would leave the data exposed during the process.

"The attacks that have been identified are really taking advantage of how CPUs have been designed for quite some time," said Ghosemajumder.

Meltdown and Spectre were discovered by researchers from Google Project Zero and academic institutions around the world.

Meltdown has currently only been identified on Intel processors. Researchers said it is unclear if processors made by ARM and AMD are also affected.

Spectre is even more pervasive, affecting everything from desktop, laptops, smartphones, and cloud servers. It's been identified on processors made by Intel, AMD and ARM, according to researchers.

The U.S. Computer Emergency Readiness Team said the flaws "could allow an attacker to obtain access to sensitive information" and that a patch would only mitigate the threat.

Many companies have already been rolling out software updates. The most important action users can take right now is to make sure they are current on any software updates, said Ghosemajumder.

Intel said in a statement it has already issued updates "for the majority of processor products introduced within the past five years. By the end of next week, Intel expects to have issued updates for more than 90 percent of processor products introduced within the past five years."

"In addition, many operating system vendors, public cloud service providers, device manufacturers and others have indicated that they have already updated their products and services," the chip maker said in a statement on Thursday.

The news prompted Intel's shares to slide more than 2 percent during trading on Thursday.

Perhaps the silver lining to all of this: US-CERT said it is not aware of any active exploitations at this time. Researchers also said they can't confirm if Spectre or Meltdown have been executed "in the wild."

But the attacks do live up to their ominous names, because even if you were compromised, researchers said you likely wouldn't even know it

Tabula Rosa Systems Blog Of 1/3/2018 How to Use the Apostrophe

====================================================

How to Use the Apostrophe

by Richard Nordquist

Updated January 02, 2018 from thoughtco.com

An apostrophe is a mark of punctuation (') used to identify a noun in the possessive case or indicate the omission of one or more letters from a word. Adjective: apostrophic.

See below for advice on using (and in some cases not using) apostrophes with possessive nouns, contractions, family names, possessive pronouns, letters, and descriptive phrases.

For the rhetorical term, see apostrophe (figure of speech).

Etymology: From the Greek, "turning away."

Basic Guidelines for Using the Possessive Apostrophe

To form the possessive of singular nouns, add 's (Homer's job, the dog's breakfast). To form the possessive of plural nouns that end in s, add an apostrophe (the bankers' bonuses, the coaches' offices). To form the possessive of plural nouns that end in a letter other than s, add 's (the women's cars, the children's lunch boxes).

"The mother's heart is the child's schoolroom." (Henry Ward Beecher)
"Children's talent to endure stems from their ignorance of alternatives."
(Maya Angelou, I Know Why the Caged Bird Sings, 1969)
"I will not hide the teacher's medication."
(Bart Simpson, The Simpsons)
"Teachers' unions are not ruining the country."
(Bart Simpson, The Simpsons)
"If we spark a student's passion, we unleash a powerful force upon the world."
(attributed to Tim Fargo)
"[T]he first instance of grading students' papers occurred at Cambridge University in 1792 at the suggestion of a tutor named William Farish."
(Neil Postman, Technopoly. Alfred A. Knopf, 1992)

"Don't let anyone tell you that apostrophes don't matter and we would be better off without them. Consider these four phrases, each of which means something different:

my sister's friend's books (refers to one sister and her friend)
my sister's friends' books (one sister with lots of friends)
my sisters' friend's books (more than one sister, and their friend)
my sisters' friends' books (more than one sister, and their friends)

(David Marsh and Amelia Hodsdon, Guardian Style, 3rd ed. Random House UK, 2010)

Apostrophes in Contractions

Apostrophes are also used in contractions (two or more words are combined to form one, with letters omitted). The classes of word which are most frequently affected by contractions are verbs and pronouns: for example, I'm, let's, you'll. . . . The apostrophe generally replaces omitted letters: for example, the o in not (doesn't)." (Ray Barker and Christine Moorcroft, Spelling First. Nelson Thornes, 2002)
"If you don't like something, change it. If you can't change it, change your attitude."(attributed to Maya Angelou)
"She wasn't doing a thing that I could see, except standing there leaning on the balcony railing, holding the universe together." (J.D. Salinger)
"Three o'clock is always too late or too early for anything you want to do." (Jean Paul Sartre, Nausea, 1938)

Apostrophes With Family Names

"This brings us to those names we see in front of houses and on mailboxes everywhere--'The Smith's,' 'The Gump's,' and even (sigh) 'The Jone's.' . . .

"Who lives in the house? The Smiths. The Gumps. The Joneses. That's what the signs should say. It's really nobody else's business whether the Smiths, the Gumps, and the Joneses own their domiciles. All we need to know is that the Smiths, the Gumps, and the Joneses live there. If you must announce possession, place the apostrophe after the plural names--'the Smiths',' 'The Gumps',' and 'The Joneses'.'"
(Richard Lederer and John Shore, Comma Sense. St. Martin's, 2005)

Descriptive Phrases Without Apostrophes

"Don't use apostrophes in such primarily descriptive phrases as a New York Mets outfielder, a teachers college, a writers manual, a childrens book, the agencies request. As the AP Stylebook helpfully notes, the apostrophe is usually skipped if 'for' or 'by' would go better than 'of' in a longer version: college for teachers, manual for writers, request by the agencies.

"In descriptive names, some organizations or institutions use the apostrophe while others don't. For instance, Diner's Club, but National Governors' Association. Consult your house style."
(Rene J. Cappon, The Associated Press Guide to Punctuation. Basic Books, 2003)

Pronouns Without Apostrophes; Letters and Numbers With Apostrophes (Sometimes)

"In the 19th century, printers and publishers attempted to standardize the system [of using apostrophes], but they still left some anomalies. They applied the rule about possession rigorously to nouns, but forgot about pronouns, so that the possessives his, hers, its, ours, yours, and theirs don't have an apostrophe. They banned the apostrophe from plurals. but allowed a number of exceptional cases, such as after numerals (the 1860's), abbreviations (the VIP's), and individual letters (P's and Q's).

"Anyone who refuses point-blank to allow an apostrophe before a plural has to surrender when they are asked to punctuate 'dot the i's and cross the t's.'" (David Crystal, By Hook or by Crook. Overlook, 2008
"Omitted Figures: The class of '62. The Spirit of '76. The '20s. Plurals of a single letter: Mind your p's and q's. He learned the three R's and brought home a report card with four A's and two B's. The Oakland A's won the pennant." (The Associated Press Stylebook and Briefing on Media Law: 2013, ed. by Darrell Christian, Sally Jacobsen, and David Minthorn. Basic Books, 2013)
"Letters of the alphabet. Some letters can be made plural by adding an s (the three Rs), but often an apostrophe is needed:

How many students received A's?
Are all the i's dotted and the t's crossed?
Mind your p's and q's."

(Amy Einsohn, The Copyeditor's Handbook, 2nd ed. Univ. of California Press, 2006)

"Decades do not have apostrophes: the 1990s." (The Economist Style Guide. Profile Books, 2010)

Apostrophes With Abbreviated Verbs

"In recent years a number of abbreviated verbs have become a part of our language, and the apostrophe is a vital ingredient in their correct spelling.

1. She OK'd the merger.
2. He was KO'd in the fifth round.
3. They OD'd on barbiturates.

. . . [T]he apostrophe is entirely legitimate here. Indeed, it is essential: not to signal the dropping of the e invites the reader to 'mispronounce' the verb, with potentially confusing results."
(Richard Palmer, Write in Style: A Guide to Good English, 2nd ed. Routledge, 2002)

Origin of the Apostrophe

"The 16th-century printers not only contributed marks for interpolations to the general repertory but also developed new marks to indicate omissions. The apostrophe is a peculiarity of written language: it was intended as a sign to indicate the elision of a vowel, but it was retained to indicate a missing letter when the vowel no longer appeared in the spoken form."
(M.B. Parkes, Pause and Effect: An Introduction to the History of Punctuation. Univ. of California Press, 1993)

G.B. Shaw on Apostrophes: "Uncouth Bacilli"

"The apostrophies [sic] in ain't, don't, haven't, etc., look so ugly that the most careful printing cannot make a page of colloquial dialogue as handsome as a page of classical dialogue. Besides, shan't should be sha"n't, if the wretched pedantry of indicating the elision is to be carried out. I have written aint, dont, havnt, shant, shouldnt and wont for twenty years with perfect impunity, using the apostrophe only where its omission would suggest another word: for example, hell for he'll. There is not the faintest reason for persisting in the ugly and silly trick of peppering pages with these uncouth bacilli. I also write thats, whats, lets, for the colloquial forms of that is, what is, let us; and I have not yet been prosecuted."
(George Bernard Shaw, "Notes on the Clarendon Press Rules for Compositors and Readers." The Author, 1901)

Gertrude Stein on Apostrophes

"[The] apostrophe has a gentle tender insinuation that makes it very difficult to definitely decide to do without it. One does do without it, I do, I mostly always do, but I cannot deny that from time to time I feel myself having regrets and from time to time I put it in to make the possessive case. I absolutely do not like it all alone when it is outside the word when the word is a plural, no then positively and definitely no, I do not like it and in leaving it out I feel no regret . . .."
(Gertrude Stein, "Punctuation in Prose." Lectures in America, 1935)

The Lighter Side of Apostrophes

"Not only do I not know what's going on, I wouldn't know what to do about it if I did."
(George Carlin)
Homer: There's your giraffe, little girl.
Ralph: I'm a boy.
Homer: That's the spirit. Never give up.
(The Simpsons)
