Comment Silicon Valley Rebrands Correspondence Courses (Score 4, Informative) 182

Attitudes towards correspondence courses don't change. News at 5.

For the record, correspondence courses have been around since 1892. But somehow MOOCs are "disruptive" (have classrooms and disruption ever gone well together?). Here's a quotation from Wikipedia to add context:

In the United States William Rainey Harper, first president of the University of Chicago, developed the concept of extended education, whereby the research university had satellite colleges of education in the wider community. In 1892 he also encouraged the concept of correspondence school courses to further promote education, an idea that was put into practice by Columbia University.[12][13] Enrollment in the largest private for-profit school based in Scranton, Pennsylvania, the International Correspondence Schools grew explosively in the 1890s. Originally founded in 1888 to provide training for immigrant coal miners aiming to become state mine inspectors or foremen, it enrolled 2500 new students in 1894 and matriculated 72,000 new students in 1895. By 1906 total enrollments reached 900,000. The growth was due to sending out complete textbooks instead of single lessons, and the use of 1200 aggressive in-person salesmen.[14][15] There was a stark contrast in pedagogy:

The regular technical school or college aims to educate a man broadly; our aim, on the contrary, is to educate him only along some particular line. The college demands that a student shall have certain educational qualifications to enter it, and that all students study for approximately the same length of time, and when they have finished their courses they are supposed to be qualified to enter any one of a number of branches in some particular profession. We, on the contrary, are aiming to make our courses fit the particular needs of the student who takes them

Comment Statistics has always had difficulty with usurpers (Score 5, Insightful) 115

Most notably psychology, economics, mathematics and beer brewing. In fact, most of the developments in stats have come about as a result of a need arising in a different discipline. Stats is inherently an applied discipline, so this is not unusual.

What is concerning is how many statistical tools, each with their own set of assumptions, have blossomed up within the past few decades. There are so many stats now that stats can no longer be an ancillary to other disciplines- it needs to be given its own space and statisticians need to be given respect for their unique expertise. There is simply too much knowledge in that domain for those in more theory-driven fields to be able to claim both expertise in the conceptual models of their fields and statistics.

One of the most important things you can possibly learn is how to tell when your source is wrong, (optionally) call them out on it, and find another source. If you can't do that, you'll forever rely on others to tell you what should be important to you and spoon-feed you "facts" about those things.

So what you're saying is that if I don't like the bullshit this idiot is spoonfeeding me, I should start listening to the bullshit some other idiot wants to spoonfeed me. Your position is logically inconsistent from my perspective- you're always going to rely on others to tell you what's important and give you information (unless you're a solipsist). I find it interesting too that you think that information sources are either categorically wrong or right- it's really way more fuzzy than that, and ultimately one's ability to determine the signal-to-noise ratio of a source is what allows one to glean the juicy bits.

Submission + - British Ambassador Says Leaks Would Have Helped Hitler (techdirt.com)

An anonymous reader writes: Where do you go when the assertions that Snowden's leaks will cause grave damage and irreparable harm to national security still fail to unite the world against the former NSA contractor? It appears you head to alternate realities where Snowden leaks documents during the early 1940s, thus dooming Britain to cowering at the feet of Hitler.

        If Edward Snowden had been around during World War II, Adolf Hitler would have been able to score victories against the United Kingdom, according to the British ambassador to the U.S.

        In remarks at The Ripon Society commemorating the U.S. and British alliance, Ambassador Peter Westmacott said leaks like Snowden's would have allowed the Nazis to overrun allied forces in the Battle of the Atlantic and gain the upper hand...

        "[T]here are moments ... when it is absolutely essential that intelligence operations in defense of our national security remain secret," he added. "These things are important. It's not frivolous and it is not hiding things."

        "It is actually necessary for our national security to ensure that our real secrets remain secret."

Submission + - KeyStore Vulnerability Affects 86% of Android Devices

jones_supa writes: IBM security researchers have published an advisory about an Android vulnerability that may allow attackers to obtain highly sensitive credentials, such as cryptographic keys for some banking services and virtual private networks, and PINs or patterns used to unlock vulnerable devices. It is estimated that the flaw affects 86 percent of Android devices. Android KeyStore has a little bug where the encode_key() routine that is called by encode_key_for_uid() can overflow the filename text buffer, because bounds checking is absent. The advisory says that Google has patched only version 4.4 of Android. There are several technical hurdles an attacker must overcome to successfully perform a stack overflow on Android, as these systems are fortified with modern NX and ASLR protections. The vulnerability is still considered to be serious, as it resides in one of the most sensitive resources of the operating system.

Submission + - Cracking Atlanta Subway's Poorly-Encrypted RFID Smart Cards Is a Breeze, PART II (ajc.com)

McGruber writes: In December 2013, Slashdot reported (http://yro.slashdot.org/story/13/12/29/1634239/cracking-atlanta-subways-poorly-encrypted-rfid-smart-cards-is-a-breeze) the arrest of seven metro Atlanta residents for allegedly selling counterfeit MARTA Breeze cards, stored-value smart cards that passengers use as part of an automated fare collection system on Atlanta's subway.

Now, six months later (June 2014), the seven suspects have finally been indicted (http://www.ajc.com/news/news/fraudulent-marta-breeze-card-ring-indicted/ngTdr/).
According to the indictment, the co-conspirators purchased legitimate Breeze cards for $1, then fraudulently placed unlimited or monthly rides on the cards. They then sold the fraudulent cards to MARTA riders for a discounted cash price. Distributors of the fraudulent cards were stationed at several subway stations.

The indictment claims that the ring called their organization the “Underground Railroad".

Comment Feasibility of Printing Massive Domes (Score 0) 69

I heard that you lived in Ithaca at one point in your life. As you might know then, it can be quite snowy in Ithaca. Do you have reason to believe that superstructures (in the style of Buckminster Fuller) could be built using 3D printing in the future, or are the technical challenges too great? Could a dome be printed? Is there any hope for keeping out at least some of the snow (perhaps not all of it as it is sometimes quite nice)?

BorisSkratchunkov writes: The ReactOS project has announced a more community-driven development approach with the launch of an IndieGoGo campaign in which contributors can push for support for specific hardware and apps. Furthermore, they have announced the impending release of ReactOS 0.4, which contains (among other improvements) USB support for the first time ever, as well as a new explorer. With the recent retirement of Windows XP and the foibles of Windows 8, it is encouraging to see that the Windows platform might not be entirely dependent on Microsoft in the future.

synaptik writes: A new documentary film, narrated by a former Star Trek actress, promotes the long-ago disproven idea that the sun revolves around the Earth. 'Everything we think we know about our universe is wrong,” says actress Kate Mulgrew as she narrates the trailer for “The Principle.' The film, which is set to be released sometime this spring, was bankrolled in part by the ultra-conservative and anti-Semitic Robert Sungenis, who maintains the blog 'Galileo Was Wrong.'
