весёлого воскресенья, негодяи.
масленичко - один из немногих почитаемых мной празднечгов.
We apply the FLUSH+RELOAD side channel attack based on cache hits/misses to extract a small
amount of data from OpenSSL ECDSA signature requests. We then apply a “standard” lattice technique to extract the private key, but unlike previous attacks we are able to make use of the side-channel information from almost all of the observed executions. This means we obtain private key recovery by observing a relatively small number of executions, and by expending a relatively small amount of post-processing via lattice reduction. We demonstrate our analysis via experiments using the curve secp256k1 used in the Bitcoin protocol. In particular we show that with as little as 200 signatures we are able to achieve a reasonable level of success in recovering the secret key for a 256-bit curve...
We extend the FLUSH+RELOAD side-channel attack of Benger et al. to extract a significantly larger number of bits of information per observed signature when using OpenSSL. This means that by observing only 25 signatures, we can recover secret keys of the secp256k1 curve, used in the Bitcoin protocol, with a probability greater than 50 percent. This is an order of magnitude improvement over the previously best known result. The new method of attack exploits two points: Unlike previous partial disclosure attacks we utilize all information obtained and not just that in the least significant or most significant bits... Furthermore, whereas previous works require direct information on ephemeral key bits, our attack utilizes the indirect information from the wNAF double and add chain.
Senator Carl Levin said companies that moved overseas were unfairly taking advantage of many of the benefits of doing business in the United States but not paying their fair share of taxes. Those benefits, he said, include “patent protection, research and development tax credits, national security and more.” He added, “They shouldn’t be allowed to shift their tax burden onto others.
Hint: At least one is mine.Will this relocation make all Pfizer and AstaZeneca drugs ineligible for purchase by the US government or programs like Medicare and Medicaid? And make these firm ineligible for R&D funds from NIH, NSF and other agencies - either directly or as "industry partners" on academic grants? I hope so. Lose US taxes - lose access to US market. It's only fair.
Globalization has long been portrayed as the rising tide that lifts all boats. The surprise is in the tide -- a rapid surge of IT-enabled connectivity that has pushed the global labor arbitrage quickly up the value chain. The rich are, indeed, getting richer but the rest of the workforce is not. This spells mounting disparities in the income distribution...
The Internet has forever changed the competitive climate for most white-collar knowledge workers: software programmers, engineers, designers, professionals toiling in legal, accounting, medical, actuarial, consulting, and financial-analyst positions -- sparing an increasingly small portion of those at the very top of the occupational hierarchy. Washington’s penchant for cutting taxes of the wealthy probably hasn’t helped matters either.
With per capita income of $38,000 and $1,700, respectively, the United States and China are at opposite ends of the spectrum. Yet both countries have extreme disparities...the poor [in China] now have real-time access to the “outside world”... the Internet has the potential to spark resentment and social instability...
Inequalities of the income distribution have long been the Achilles’ heel of economic growth and development...that seems more the case than ever. History tells us that the pressures of widening income disparities are often vented in the political arena.
This is Lady Pine's follow-up to her post about peculiar AWS pricing anomalies that I was so excited about at the time.
It seems like Amazon changed their reserve price algorithm last July, using a non-symmetric algorithm instead of the AR(1) up-down symmetric algorithm, and changing floor and ceiling values. Then in October it seems like they returned to using a simple constant minimal price algorithm, with yet a new level of a minimal price!
Was our paper a reason for the abandoning of the (no longer) hidden dynamic reserve price?
I found a video on YouTube while browsing, randomly. Maybe. YouTube is a Google digital property. I don't try to hide from Google. Their personalized advertising knows me too well. The video is near-future fiction, about the destiny of newspapers.
Citizen journalism has generated excitement as an alternative to traditional news media. I first came across the idea in 2009, after reading about SXSW in Austin, Texas.
Blogs are another relatively recent form of non-traditional media, offering current events analysis, movie reviews, historical retrospectives, educational materials and photographs. Forbes Online and The Huffington Post are non-traditional media publishers. I prefer Forbes, as their contributors are better. Arianna Huffington has a reputation for paying writers poorly, or nothing at all. That probably accounts for Huffington Post quality issues! The decent reporters leave, in order to earn a living wage. There are smaller, very active specialty websites, such as StockTwits, reddit, Seeking Alpha and Slash Dot. Other platforms, e.g. Twitter and identi.ca, enable terse real-time reporting by the public.
Nothing but a collection of trivia, much of it untrue, all of it narrow, shallow and sensational - That's what The New York Times thinks of blogger journalists, according to this!
The whole issue of providers feeding you things "you like" is sort of like inbreeding. We only see stuff we've already seen before, and soon everyone is pigeon-holed into a deficient world view of their own making. There is no new DNA in your thought patterns and soon the genetic mutations rise to the top and we're left with a world full of retarded ideas.
And in this new world, who will dig out the facts on which stories might be based? Or will we all be relying on machine generated gossip? Will Pinky even be able to pay her rent?
About one thing I am certain: In 20 years there will be no more printed newspapers. If they do exist, they will be considered a luxury item for certain hotels to offer as an extravagant service for their guests. Printed newspapers will no longer be normal in 20 years.
During Murdoch’s heyday, it was impossible for one company to consolidate production, distribution, editorial and advertising functions across all forms of media and across national borders. The internet makes that, if not easy, for the first time, possible.

Instead of paying for air-conditioning at some Pennsylvania warehouses, Amazon had just stationed paramedics outside to take the inevitably heat-stressed workers to the hospital.
The Enlightenment is also known as "The Age of Reason" because of the remarkable advances in science and rational thought that are associated with the 200 years between 1650 and 1850. I always believed that we unequivocally benefited from the Enlightenment, but I just learned of an alternative point of view.
There are some portions of this post about the Enlightenment with which I am uncomfortable. Be that as it may, it is worthwhile to learn from the history cited.
N.B. In my post, every indented and block quoted item that is excerpted from the "Simple To Remember" website written by Aish-affiliated Rabbi Ken Spiro unless indicated otherwise. Emphasis mine, throughout.
One of the casualties of The Enlightenment was organized religion. Religion was perceived as an intellectual shortcoming, like superstition, rather than science. Secular culture is the Rationalist alternative to religion. Given that, I thought this conclusion was peculiar:
As odd as it may sound, the less religious the Western world became, the better it treated the Jews.
Jews were specifically granted some basic, though still not equal rights in 1791. Per the French National Assembly:
The conditions requisite to be a French Citizen are fixed by the constitution...every man who takes the civic oath...has a right to all the advantages it insures; all adjournments, restrictions, and exceptions affecting individuals of the Jewish persuasion are annulled for those Jews who shall take the civic oath.
It sounds very fine! I could not conceive how it could be objectionable, yet this was Aish's view:
Judaism believes that for an ideal world there must be a focus on both God and man. Because without a focus on God, all moral values become relative.
I don't know what causes moral values to become relative. I do know, with certainty, that moral relativism is bad. I have seen evidence of it:
For a while, it might be nice to have respect for civil rights, but when it becomes convenient or necessary (for various social or political reasons) to change that focus, then respect for human life becomes just another idea that goes out of style.
I did not realize that Napoleon Bonaparte marched through Europe, liberating Jews from their ghettos, wherever he could. Napoleon said,
I will never accept any proposals that will obligate the Jewish people to leave France, because to me the Jews are the same as any other citizen in our country. It takes weakness to chase them out of the country, but it takes strength to assimilate them.
He [Napoleon] wanted the Jews to be accepted by the rest of European society...So, he set about to help the Jews rid themselves of the things that set them apart. Napoleon was asking the Jews to answer the great question that came out of emancipation: What is your primary identity? Are you first and foremost Jews or Frenchmen?
This rings true:
Once the gates of the ghettos were thrown open, the Jews rose to the top quickly, gaining prominence and wealth.
It is consistent with what my grandparents told me. This too:
In theory Jews had equal rights but in practice, the story was very different. Many Jews saw conversion as the best way to advancement in enlightened Europe.
Jews were accepted into society, just as long as they were not too Jewish.
The term anti-Semitism came to prominence during the late 19th century. It is attributed to Wilhelm Marr, a German writer, from a pamphlet he published in 1879. Anti-Semitism was intended to differentiate between antipathy for Judaism as a religion versus antipathy for Jews as a so-called race or nation.
In Germany, Jews prospered visibly. They contributed to German industry, commerce, the arts and scientific discovery. Be that as it may, the "writing was on the wall" (or should have been, that all was not well) when The Question of the Jew is a Question of Race and/or Die Judenfrage als Frage der Racenschaedlichkeit (both published in 1881) by Eugen Karl Dühring, were well-received throughout Germany. Many copies were sold, over the next two decades, equivalent to what we consider to be a best seller today. The book(s) conclusion was that the distinction between Jewish religion and Jewish race is false. Instead, they are one and the same, inextricably linked. The logical consequence is that it is irrelevant whether Jews consider themselves to be Jewish. That viewpoint remains relevant in the 21st century, regardless of whether it is accurate.According to Karl Duehring, and the more formalized anti-Semitism that followed, it doesn't matter if Jews convert to Christianity. Being non-secular or striving to contribute to the community, culture, including military service, is of no significance. Anti-Semitism as a social and cultural ideology did not care what the Jews of Germany believed about their status as former Jews, nor how non-Jewish they behaved. All that mattered was that they were identifiable as Jews.
The New York State Comptroller recently announced that 2012 aggregate Wall Street bonuses are $20 billion, an 8% increase over last year. Oddly, the average salary for a Wall Street worker is more than it was prior to the 2008 financial collapse. It is also five times greater* than what most workers in New York City earn.
Consolidation of wealth and income doesn't spare the financial services sector. I've said that for awhile. Finally, here's a shred of proof. Employment has dropped 10%, a loss of approximately 20,000 jobs, in the Wall Street job market due to company downsizing. Yes, there was more money made last year, but for fewer people. For further depressing details, see Wall Street Bonuses Are Up 8%! Happy Hump Day! via Village Voice (27 Feb 2013) and ABC News.
* The comparative earnings data is from 2011, so I'd expect 2012 to show even greater disparities. After all, we are in the midst of an economic recovery. Correct?
It's almost impossible to keep a web server secret by not publishing links to it. As soon as someone follows a link from your "secret" server to another web server, your "secret" URL may appear in the referrer tag and can be stored and published by the other web server in its referrer log. Similarly, the web has many outdated and broken links. Whenever someone publishes an incorrect link to your site or fails to update links to reflect changes in your server, Googlebot will try to download an incorrect link from your site.
I am thrilled to announce the publication of Mi Yodeya's haggadah supplement! At the Pesach seder we are supposed to ask questions (about the exodus from Egypt and about the rituals of the seder...). Mi Yodeya, a top-notch Jewish Q&A site (if I do say so myself :-) ), is all about questions. So we compiled some of ours that are on-topic for the seder into a book, a supplement to the haggadah. I hope you'll download a copy for possible use at your own seder (or just to read)...
Go to http://s.tk/miyodeya for more info and a download link.
I'm happy they pulled it off. I am an occasional visitor to Mi Yodeya, a member of the Stack Exchange family of Q&A websites. I spend a lot of time at all the sites collectively, but am not nearly as eclectic, yet knowledgeable as M. Cellio.
