An anonymous reader writes "A new study of asteroid craters on the moon has uncovered some big differences in the composition of the crust on the two sides of the moon. 'While massive impact basins pockmark the moon's near side, its far side contains considerably smaller basins. The discrepancy in crater distribution has puzzled scientists for decades. To investigate what may have caused this difference, the team obtained data from NASA's twin GRAIL probes, which orbited the moon from January to December 2012. During its mission, the probes circled the moon, making measurements of its gravity. Zuber and her colleagues used this data to generate a highly detailed map of the moon's crust, showing areas where the crust thickens and thins; in general, the group observed that the moon's near side has a thinner crust than its far side.'"

rtoz writes "For handling the future unreliable chips, a research group at MIT's Computer Science and Artificial Intelligence Laboratory has developed a new programming framework that enables software developers to specify when errors may be tolerable. The system then calculates the probability that the software will perform as it's intended. As transistors get smaller, they also become less reliable. This reliability won't be a major issue in some cases. For example, if few pixels in each frame of a high-definition video are improperly decoded, viewers probably won't notice — but relaxing the requirement of perfect decoding could yield gains in speed or energy efficiency."

ananyo writes "Using data pulled from online genealogy sites, a renowned 'genome hacker' has constructed what is likely the biggest family tree ever assembled. The researcher and his team now plan to use the data — including a single uber-pedigree comprising 13 million individuals, which stretches back to the 15th century — to analyze the inheritance of complex genetic traits, such as longevity and facial features. In addition to providing the invitation list to what would be the world's largest family reunion, the work presented by computational biologist Yaniv Erlich at the American Society of Human Genetics annual meeting in Boston could provide a new tool for understanding the extent to which genes contribute to certain traits. The pedigrees have been made available to other researchers, but Erlich and his team at the Whitehead Institute in Cambridge, Massachusetts, have stripped the names from the data to protect privacy."

jfruh writes "Most day-to-day programmers have only a general idea of how compilers transform human-readable code into the machine language that actually powers computers. In an attempt to streamline applications, many compilers actually remove code that it perceives to be undefined or unstable — and, as a research group at MIT has found, in doing so can make applications less secure. The good news is the researchers have developed a model and a static checker for identifying unstable code. Their checker is called STACK, and it currently works for checking C/C++ code. The idea is that it will warn programmers about unstable code in their applications, so they can fix it, rather than have the compiler simply leave it out. They also hope it will encourage compiler writers to rethink how they can optimize code in more secure ways. STACK was run against a number of systems written in C/C++ and it found 160 new bugs in the systems tested, including the Linux kernel (32 bugs found), Mozilla (3), Postgres (9) and Python (5). They also found that, of the 8,575 packages in the Debian Wheezy archive that contained C/C++ code, STACK detected at least one instance of unstable code in 3,471 of them, which, as the researchers write (PDF), 'suggests that unstable code is a widespread problem.'"

rtoz writes "Researchers at MIT have succeeded in producing and measuring a coupling of photons and electrons on the surface of an unusual type of material called a topological insulator. This type of coupling had been predicted by theorists, but never observed. The researchers suggest that this finding could lead to the creation of materials whose electronic properties could be 'tuned' in real time simply by shining precise laser beams at them. This work opens up a new avenue for optical manipulation of quantum states of matter. Their findings suggest that it's possible to alter the electronic properties of a material — for example, changing it from a conductor to a semiconductor — just by changing the laser beam's polarization. For example, a property called a bandgap — a crucial characteristic for materials used in computer chips and solar cells — can be altered by shining a polarized laser beam at the material."

rtoz writes "Heating or cooling certain parts of your body — such as applying a warm towel to your forehead if you feel chilly — can help maintain your perceived thermal comfort. Using that concept, four MIT engineering students developed a thermoelectric bracelet that monitors air and skin temperature, and sends tailored pulses of hot or cold waveforms to the wrist to help maintain thermal comfort. The product is now a working prototype. And although people would use the device for personal comfort, the team says the ultimate aim is to reduce the energy consumption of buildings, by cooling and heating the individual — not the building. The team estimates that if the device stops one building from adjusting its temperature by even just 1 degree Celsius, it will save roughly 100 kilowatt-hours per month."

New submitter _0xd0ad sends this news from the CS Monitor: "The activities of bantam water droplets in just one region of a power plant could make a significant difference in the output of power plants, scientists say. ... When a water droplet forms on a sheet of metal coated with a superhydrophobe, the droplet can camp there only so long as it does not merge with another droplet. As soon as it weds with another droplet, the energy produced is so great that the two will 'jump' away from that surface, as if in urgent deference to the surface's severe water phobia. Scientists have proposed that this 'jumping' could be incorporated into power plant design. ... 'To have the most efficient condensing surface, you want to remove the droplets as early as possible,' says Dr. Nenad Miljkovic, [postdoctoral associate at MIT and co-author on 'Electrostatic charging of jumping droplets']. But, in prototypes, this 'jumping' design is not as efficient as engineers believe it could be. Some of the droplets will just fall back to the condenser's surface, recoating it and slowing the process down. ... But a newly discovered component to the 'jumping' process might allow scientists to eliminate this fall back. In an accidental find, the MIT team found that droplets don't just spring from the surface — they also rebound from each other ... because an electrical charge forms on the droplets as they flee the hydrophobic surface. So, if a charge is applied to the condenser system, the water droplets can be electrically prevented from returning to the surface, he said.

MIT research scientist John Romanishin, along with professor Daniela Rus and postdoc Kyle Gilpin, have demonstrated a swarm of modular robots with the ability to self-assemble into larger shapes. The individual robots are small and cubical, but they contain a flywheel capable of spinning at 20,000 rpm. By spinning up the flywheel and then braking abruptly, the robots use angular momentum to jump into different positions. Magnets on the edges of the cube guide them into alignment. The researchers hope to be able to shrink the cubes even further, but they think a "refined version of their system could prove useful even at something like its current scale. Armies of mobile cubes could temporarily repair bridges or buildings during emergencies, or raise and reconfigure scaffolding for building projects. They could assemble into different types of furniture or heavy equipment as needed. And they could swarm into environments hostile or inaccessible to humans, diagnose problems, and reorganize themselves to provide solutions." The cubes could also be packed with sensors, batteries, or other technologies.

coondoggie writes "Researchers at the Massachusetts's Institute of technology say they have developed an antenna for small satellites (known as cubesats) that can fold into a compact space and inflate when in orbit. The inflatable antenna lets a CubeSat transmit data back to Earth at a distance seven times farther than that of existing CubeSat communications."

mikejuk writes "Researchers at MIT Media Lab are working on an automated personal-computer-based system designed to help people improve interpersonal and conversational skills. The software is called MACH, short for My Automated Conversation coacH (pdf). It makes use of a computer-generated onscreen face to simulate interactive conversations. It performs facial, speech, and behavior analysis and synthesis to emulate human-to-human responses. At the end of the session it provides the user with feedback on their performance. Using a webcam the program can analyze facial expressions, including smiling and head gestures while its voice recognition system analyzes not only what you say but also how you say it and notes non-verbal vocalizations. As feedback you watch the video side-by-side with the analysis of your behavior — see the video of it in action. It has already been shown to improve job interview techniques and other potential uses are coaching in public speaking and dating."

A group of researchers from MIT and the University of Ireland has presented a paper (PDF) showing that one of the most important assumptions behind cryptographic security is wrong. As a result, certain encryption-breaking methods will work better than previously thought. "The problem, Médard explains, is that information-theoretic analyses of secure systems have generally used the wrong notion of entropy. They relied on so-called Shannon entropy, named after the founder of information theory, Claude Shannon, who taught at MIT from 1956 to 1978. Shannon entropy is based on the average probability that a given string of bits will occur in a particular type of digital file. In a general-purpose communications system, that’s the right type of entropy to use, because the characteristics of the data traffic will quickly converge to the statistical averages. ... But in cryptography, the real concern isn't with the average case but with the worst case. A codebreaker needs only one reliable correlation between the encrypted and unencrypted versions of a file in order to begin to deduce further correlations. ... In the years since Shannon’s paper, information theorists have developed other notions of entropy, some of which give greater weight to improbable outcomes. Those, it turns out, offer a more accurate picture of the problem of codebreaking. When Médard, Duffy and their students used these alternate measures of entropy, they found that slight deviations from perfect uniformity in source files, which seemed trivial in the light of Shannon entropy, suddenly loomed much larger. The upshot is that a computer turned loose to simply guess correlations between the encrypted and unencrypted versions of a file would make headway much faster than previously expected. 'It’s still exponentially hard, but it’s exponentially easier than we thought,' Duffy says."

Daniel_Stuckey writes "When you walk around a city, there are things you can just sense, like if you've wandered into a dodgy neighborhood, or where the new happening spot is. Intuitively, we know that a city's more intangible characteristics, like class or uniqueness, play a big role in what it’s like to live there, but until now there was no way to actually quantify that idea. Researchers from MIT Media Lab may have found a way to measure this 'aesthetic capital' of cities, with their website Place Pulse, a tool to crowdsource people's perception of cities by judging digital snapshots—a sort of 'hot or not' for urban neighborhoods. Some 4,000 geotagged Google Streetview images and 8,000 participants later, the team found that by using digital images and crowdsourced feedback, they can accurately quantify the diverse vibes within a city (pdf), which in turn can help us better understand issues like inequality and safety."

An anonymous reader writes "MIT is claiming they can make the Internet faster if we let computers redesign TCP/IP instead of coding it by hand. They used machine learning to design a version of TCP that's twice the speed and causes half the delay, even with modern bufferbloated networks. They also claim it's more 'fair.' The researchers have put up a lengthy FAQ and source code where they admit they don't know why the system works, only that it goes faster than normal TCP."

Dputiger writes "In the wake of activist Aaron Swartz's suicide, MIT launched an investigation into the circumstances that led to his initial arrest and felony charges. It's now clear that the move was nothing but a face-saving gesture. Moments before the court-ordered release of Swartz's Secret Service file under the Freedom of Information Act, MIT intervened, asking the judge to block the release. Supposedly this is to protect the identities of MIT staff who might be harassed — but government policy is to redact such information already."

Nerval's Lobster writes "The same layers of virtualization that have made networked business computing so much more convenient and useful have also given bad guys much easier access to both physical and virtual servers within previously-secure datacenters. A group of engineering researchers from MIT has demonstrated one approach to making secure servers harder to access using a physical system that prevents attackers from reading a server's memory-access patterns to figure out where and how data are stored. Ascend, which the group demonstrated at a meeting of the International Symposium on Computer Architecture in Tel Aviv in June (PDF), is designed to obscure both memory-access patterns and the length of time specific computations take to keep attackers from learning enough to compromise the server. The approach goes beyond simply encrypting everything on the whole server to try to shut off one of the most direct ways attackers can address the server directly — whether the server is an air-gapped high-security machine sitting in an alarmed and guarded room at the NSA or a departmental server whose security settings are a little too loose. Other ways to try to obscure memory-access patterns were built as applications to run on the server. Ascend is the first time a hardware-only approach has been proposed, and the first to approach an acceptable level of performance, according to Srini Devadas, Edwin Sibley Webster Professor of Electrical Engineering and Computer Science, the MIT researcher who oversaw the team developing the hardware."

theodp writes "Two decades before the White House was petitioned to remove U.S. Attorney Carmen Ortiz and her Assistant U.S. Attorney Stephen Heymann from their jobs for the allegedly overzealous prosecution of Aaron Swartz, the Boston Globe reported on allegations of 'sometimes heavy-handed tactics and inaccuracies' of an NFL investigation into sexual harassment charges made by a sportswriter against the New England Patriots that was led by Watergate prosecutor Philip Heymann (Stephen's father) and included Ortiz. 'From the day Philip Heymann and his colleagues walked into Foxboro Stadium to investigate Lisa Olson's charges of sexual harassment,' the Globe reported, 'the New England Patriots were on the defensive, and apparently, they stayed there to the end. One day after conducting a preliminary six-hour interview with Olson, Heymann introduced each investigator to the Patriots and outlined their backgrounds at a meeting he later called benign. Yet he also said two weeks ago, "They were frightened from the beginning by the way I introduced people. I said that Jerry O'Sullivan had been US Attorney. I said Jim Ring had been FBI special agent in charge of organized crime."'

Regarding Ortiz, the Globe reported, 'Heymann investigator Carmen Ortiz wrote in a memo of her Oct. 18, 1990, interview with [Lisa Olson] that she took no notes and did not tape-record the conversation. Yet she used direct quotes when writing up her 15-page report on the session. When asked to explain, she referred the Globe to Heymann.' Aside from transcripts of two interviews (the tapes of which were destroyed), the Globe reported the NFL kept no notes on its interviews with 89 other people. '"It was contemplated that there would be a motion such as this [a lawsuit by Olson] and we did not want to create that type of document," an NFL attorney explained. According to the Globe, an attorney representing the Patriots said that 'one reason the tapes were destroyed may be that the NFL did not want anyone to hear raised voices or pounding of tables. He said some of those interviewed were not allowed to leave the room and had their livelihoods threatened if they did not cooperate.' Curiously, the elder Heymann featured prominently in a recently-upheld DOJ motion to keep the names of key people involved in the Aaron Swartz case secret — a postcard threat received by Philip Heymann was cited by Ortiz's office as evidence of why such secrecy was necessary."

Nnaemeka adds, 'It just looks like we've shifted the malpractice from feeding the money machine to making inane, self-centric apps. Worse, is that the power players, institutional and individual — the highflying VCs, the entrepreneurship incubators, the top-ranked MBA programs, the accelerators, the universities, the business plan competitions have been complicit in this nonsense.' And while it may not get you invited to the White House, Nnaemeka advises entrepreneurs looking for ideas to 'consider looking beyond the city-centric, navel-gazing, youth-obsessed mainstream' and instead focus on some groups that no one else is helping."

schirra writes "The MIT Game Lab has just released the graphics/physics engine from its popular game A Slower Speed of Light as an open-source project, allowing anyone to play around with the effects of special relativity using Unity3D. While the hope is that game developers and educators will use OpenRelativity to develop new kinds of relativistic games and simulations, that shouldn't stop those with a casual interest from playing around with these wicked cool effects. For the physics inclined, these effects include Lorentz contraction, time dilation, Doppler shift, and the searchlight effect--though a PhD in theoretical physics isn't required to enjoy or use the project."

CowboyRobot writes "Businesses should seed their password databases with fake passwords and then monitor all login attempts for use of those credentials to detect if hackers have stolen stored user information.

Rivest (the 'R' in 'RSA'). Honeywords aren't meant to serve as a replacement for good password security practices. But as numerous breaches continue to demonstrate, regardless of the security that businesses have put in place, they often fail to detect when users' passwords have been compromised."

Preferably cross-platform, or browser-based, so she can show her work at school (Windows) as well as work on in at home (Debian Linux).

MIT's Emergency Information page also reports that injuries have been reported. Sadly, CNN is now reporting that the university police officer has died. Look for updates on Twitter." The two suspects identified earlier as being behind the Boston Marathon bombings are believed to be responsible for this. They were found by police. One suspect, 26-year-old Tamerlan Tsarnaev, was killed in a shootout. The other suspect, 19-year-old Dzhokhar Tsarnaev, is still being pursued. The Associated Press reports that the two are believed to be from the Russian region near Chechnya. During the firefight, the suspects threw explosive devices at police. Public transit in Boston has been shut down, and hundreds of thousands of people have been asked to not leave their homes. Here are live feed for local TV news and emergency services audio. Police have been warned that the remaining suspect may have a suicide vest.

Reader Okian Warrior points out a related story worthy of notice: "The 4chan crowd, poring over images of the Boston marathon, identified two dark-skinned and bag-carrying suspects (among others). This was then picked up by The New York Post, who ran the image on Thursday's front page with the headline 'Feds seek these two pictured at Boston Marathon.' And now, a completely innocent teen now finds himself scared to leave his home."

astroengine writes "NASA has selected a $200 million mission to carry out a full-sky survey for exoplanets orbiting nearby stars. The space observatory, called the Transiting Exoplanet Survey Satellite, is scheduled for a 2017 launch. Like the currently operational Kepler Space Telescope, TESS will be in the lookout for exoplanets that orbit in front of their host stars, resulting in a slight dip in starlight. This dip is known as a "transit" and Kepler has revolutionized our understanding about planets orbiting other stars in our galaxy by applying this effective technique. As of January 2013, Kepler has spotted 2,740 exoplanetary candidates. "TESS will carry out the first space-borne all-sky transit survey, covering 400 times as much sky as any previous mission," said TESS lead scientist George Ricker, of the Massachusetts Institute of Technology Kavli Institute for Astrophysics and Space Research. "It will identify thousands of new planets in the solar neighborhood, with a special focus on planets comparable in size to the Earth.""

Together with our colleagues dedicated to campus safety and security, with the support of senior academic leadership and in collaboration with the campus community, we are deploying all necessary resources to this effort. It will require the dedication of all of us to promote safety awareness, complete necessary emergency training, and adhere to reinforced cyber security guidelines. IS&T staff members are working with information technology (IT) leadership and partners across campus in making the changes described above. We continue to explore all opportunities to further strengthen our preparedness, and will communicate additional information as these plans evolve.'"

An anonymous reader writes "MIT announced that despite a long history of running an open network (so that any student can run a server on any port, without any questions asked), it will now end this policy due to recent denial-of-service attacks and gunman hoax. From a letter sent by Executive Vice President and Treasurer Israel Ruiz: 'I am deeply and personally committed to safeguarding our community, protecting our campus and securing our systems. Together with our colleagues dedicated to campus safety and security, with the support of senior academic leadership and in collaboration with the campus community, we are deploying all necessary resources to this effort. It will require the dedication of all of us to promote safety awareness, complete necessary emergency training, and adhere to reinforced cyber security guidelines. IS&T staff members are working with information technology (IT) leadership and partners across campus in making the changes described above. We continue to explore all opportunities to further strengthen our preparedness, and will communicate additional information as these plans evolve.'"

Hugh Pickens writes writes "It's been said that social graces may be just as important as intelligence and engineering prowess to success as an astrophysicist or computer engineer. But how do you take someone who's grown up in the world of pocket protectors and get them thinking about suits, bow ties and the proper way to hold a wine glass. Now Jennifer Lawinski reports that MIT's Charm School just celebrated its 20th birthday with classes in alcohol and gym etiquette, how to dress for work and how to visit a contemporary art museum. 'We're giving our students the tools to be productive members of society, to be the whole package,' says Alana Hamlett. 'It gets them thinking about who they are and what their impact and effect is, whether they're working on a team in an engineering company, or in a small group on a project, or interviewing for a job.' At this year's Charm School students were free to drop in and participate in any of the 20-minute mini-courses being offered that day and students who participated in 10 of the mini-courses were awarded doctorates of charm. Computational biology graduate student Asa Adadey said the free meal was a draw and said he learned in one mini-course not to cut up all his meat at once before eating it. 'Who knows? Down the line I may find myself at a formal dinner.'"

curtwoodward writes "MIT researchers looked at 150 of the school's spin-out companies in manufacturing businesses over a decade, and found many of them hit the same chasm: Once it was time to ramp up to large-scale production, they couldn't find domestic investors and had to go overseas. The bulk of the research will be published later this year, but it raises an interesting conundrum — if an MIT-pedigreed company has serious trouble ramping up production in the U.S., how much harder is it for the 'average' business that wants to grow? Is it even still possible to do high-tech manufacturing here — or should it be?" Intel seems to be doing OK with U.S. manufacturing, but they have the advantage of established operations.

An anonymous reader writes "MIT has posted a letter to campus newspaper The Tech providing a timeline of last weekend's 'gunman' hoax. On Saturday morning, Cambridge, MA police were contacted via Internet relay by a tipster who claimed that a someone wearing armor and carrying a 'really big gun' was in Building 7 at MIT (the Massachusetts Ave. entrance to the Infinite Corridor) and was heading towards the office of MIT President Rafael Reif. The call continued for 18 minutes, with the caller eventually claiming that the gunman was seeking to avenge the suicide of Aaron Swartz, who was being prosecuting for alleged illegal downloads of millions of journal articles using MIT's computer network. The caller also identified the gunman as an MIT staff member, who has since been questioned by police and cleared. MIT has been criticized for waiting 1.5 hours before sending a campus-wide alert after the call was received."

A couple of weeks ago you had the chance to ask Khan Academy lead developer Ben Kamens about the future of online education and the academy itself. Below you'll find his answers to the questions we sent and a few extra that he found interesting. Higher Education
by null etc.

Joel Spolsky has famously stated that he prefers software engineers who come from highly accredited universities, preferably Ivy-league. His thought is that one has to distinguish oneself in order to be granted admission to such places. Do you think that Joel's opinion, and those of other elitist employers, will change with the introduction of free, quality online education?

Kamens:Yes. It's not just access to education, it's the ease with which somebody can demonstrate their ability. Ask any developer if they'd sleep better at night having just hired:

A) somebody from a no-name school with an impressive github profile and side projects
B) somebody from an impressive school with no github profile nor side projects

Then take everybody who answered B and keep them away from me. And here's the thing: I'm confident Joel agrees. Joel's most famous edict when it comes to hiring is making sure somebody's "Smart and Gets Things Done." There was a time when a college degree was the best credential for Smart and Gets Things Done. In many hiring situations, it still is.

In the programming world right now? Not so much. There are too many chances to prove your ability before you graduate for that name on your degree to carry all the weight. Sure, between two otherwise equal candidates, neither of whom have littered the internet with blog posts and side projects and bits of their code, highly accredited universities can still help differentiate. It's a helpful filter, especially when sorting through thousands of otherwise similar resumes.

Even at Fog Creek 6 years ago, graduating from a top-tier university only gave you one point (out of 6 possible) in the initial resume screening process...which was the most trivial part of an otherwise lengthy recruiting pipeline designed to figure out if you're Smart and Get Things Done.

Short version: yes, this is changing and will continue to. Quality online education will hopefully continue advancing alongside easier and easier ways to demonstrate your skills to the world. At Khan Academy, we've hired people from all sorts of colleges (even three high schoolers!) who've demonstrated tremendous skill way before a degree credentials it. We'll continue to do so.



Platform For Schools
by GeneralSecretary

I've heard that KhanAcademy has a platform for schools. Students can learn using Khan Academy and teachers can monitor their progress and help students where they need it most. When I last heard about this the platform was a pilot program being launched at select schools. Are there plans to make this platform generally available? or even open source?

Kamens:It's actually for any teacher in any school right now, for free. Our "teacher toolkit" is the best place to start, w/ videos of other schools' usage and tips from their implementations.

When a teacher signs up and gets their class on Khan Academy, they'll get the exact same platform our pilot classrooms receive. Same product a parent would get if they signed up with their child. Those teachers in the pilot program you mention aren't using anything special.

The significant difference is our ability to personally engage with specific teachers and classrooms. We're a small team and have to focus on a (relatively) small number of classrooms. We use these few pilots to get feedback, learn from students, try to understand how our product can empower teachers, etc. But any changes we make as a result are then given to all students around the world.



Verification
by GeneralSecretary

It seems to me that the problem with online education is being able to prove what you have learned. I can learn Calculus online at Khan Academy or at my local community college. I'll probably learn Calculus better at Khan Academy and for less money. But, I cannot use that knowledge to get a degree nor would I have any other way of proving my knowledge to other schools or potential employers. Do you have a solution to this problem?

Kamens:It's a big deal. The MOOCs have already started tackling this. Coursera, Udacity, and edX are working with colleges to provide official credit for their online classes.

There's more than one way to work this issue. The MOOCs are attempting to build an educational brand that's valued in much the same way as, say, Stanford. They can then hand out stamps of approval that serve as signals for employers or colleges who're trying to assess candidates.

There's also the github model. Github doesn't bill itself as an accreditation machine. It doesn't try to hand out branded stamps of approval. But talk to employers about the power of github profiles and you'll hear an interesting story. And they're not the only ones. Sites like Stack Overflow have managed to build systems of reputation that send meaningful signals (disclosure: I'm biased about Stack Overflow).

Bottom line: your question represents an *enormous*, world-changing opportunity, and Khan Academy has some important choices to make. The team is sprinting on this problem as I type.



Where are all the CS courses?
by Anonymous Coward

Where are all the "traditional" Computer Science courses? I'm not asking about the "interactive manual" type courses like how to do loops in Python - there are a ton of materials about that all over the web. I'm asking about theoretical computer science, such as Turing completeness, Chomsky hierarchy, abstract data types, compiler design, that kind of stuff which is the backbone of a university computer science education. The reason I'm asking is not to diminish the value of hands-on courses, but because many (including myself) were not able to get a "traditional" CS degree, coming into programming jobs from other disciplines (or no degree at all) and are largely self taught. Self teaching is great when it comes to practical stuff early on, but once you move on to more senior roles you start feeling the gaps of not understanding the theory behind your tools, design, and implementation, as much as you should.

Kamens:Agreed!

I'd encourage you to check out the computer science section we have. While it's not the high-level content you mention, it's far from those "interactive manuals" you see around the web. John Resig and his team have built something pretty special.

That being said, the most honest answer we can give when asked about missing content is that we've chosen to focus on a few topics (like core math) until we nail them and the experience built around them.

We're opportunistic when we find an incredible person to help us teach other areas while the rest of the team focuses on core math. Examples would be Dr. Beth Harris and Dr. Steven Zucker's Art History content and Vi Hart's brilliant and somewhat indescribable videos.

We are building quite a content team. There's little we don't hope to cover one day. Just not focusing on higher-level CS *yet*.



Explanation vs exploration: Pedagogical challenge?
by fantomas

I've heard a criticism of the Khan Academy pedagogic approach is that it is explanation based (effectively the old model: the teacher talks, the student listens, the student carries out an exercise, listens again) - while schools are moving towards exploration based learning (where students are encourage to try and approach problems from different angles supported by teacher-as-facilitator). To what extent does Khan Academy replicate a very old fashioned rote-learning form of education (albeit delivered and presented via a new media with minor improvements like pause and rewind), and in what aspects does it offer significant new pedagogical advances in learning?

Kamens:Dangit, I just listened to Sal answer this exact question at a dinner yesterday. Now you're gonna make me feel like I'm a puppet. I'll do my best to break free of these puppet shackles and answer with my own words.

The fundamental belief of Khan Academy is that students should engage with content they need on-demand, at their own pace. We agree that any curriculum that forces all students in a class to follow the same, preordained "watch this video, do this exercise, watch this other video" path isn't using technology in a meaningful way. So we design our product and work with teachers to help students feel ownership of the learning process.

Our classrooms see varying implementations, but the best of them try hard to help students move at their own pace. Some students might never need to listen to Sal say a word. They can master content by experimenting on their own. Absolutely. Fine. By. Us. Others may benefit from rewinding one of Sal's videos over and over and over until a concept clicks. But not every student masters content at the same speed.

It takes a fearless teacher to embrace this controlled chaos in a classroom. I've seen it happen. I have the highest respect in the world for those teachers able to do it. They're simultaneously ready to help mentor a student who's stuck working on fractions and another who may've advanced all the way to trigonometry. They let one student run free on her own while giving another strong encouragement to try the next challenge. Watching these teachers in action is a sight to behold.

Khan Academy exists to give students the freedom to engage with the content they need while giving teachers immediate feedback about who's working on what and where they need help. We think we can help teachers by making this acquisition of core skills a more personalized, efficient process.

In doing so, we hope to move teachers _up_ the value chain so they can focus on exploration-based learning and targeted coaching with the rest of their class time.

I personally think that'd be a significant advance in learning. And FWIW, we consider anybody who fights for exploration-based learning to be an ally of Khan Academy.



Plans to make KA easier for researchers to use?
by Anonymous Coward

I'm a middle school teacher experimenting with using KA with my classes. I think it is an amazing tool, especially for differentiation -- helping teachers to help their students who are behind have successes in math and, ideally, work towards getting caught back up to their peers. I think it can allow math teachers to do more interesting and fun (non-drill) types of work in the classroom, such as focusing more on students learning by doing open-ended, authentic, rich projects with each other. The key word there is that I *think* it must be helpful to the type of classroom described above. I want to know it is, and as part of our practice in Ontario, Canada, it is encouraged that teachers engage in personal inquiry projects to get more data on whether what we think is working actually is. It is difficult to get the data I need out of KA. We're having to do a lot of manual grabbing of student usage times and populating spreadsheets with that. Any plans to extend the external API to allow more sophisticated queries? Or, perhaps plans to provide a tool allowing more extensive data dumps which researchers can use? And if you don't have plans at the moment, does this post influence that? ;-) With a more thorough access to student data, I expect there will be researchers who will be more interested in investigating KA in their research and fleshing out the actual benefits (and also any issues that might be addressed). My students and I thank you!

Kamens:Holy crap, I should've just pasted your first couple sentences in response to the previous question! Would've been way more authentic.

Ouch. This one hits home. I want our API to support this type of thing, and I know it's far from perfect. Can you make sure the specific API queries you need are requested here? We haven't had time to do everything we want, but we're always on the lookout for big API wins that'll enable the community to build cool stuff. Thanks for being an early API adopter. Sorry you've had trouble. Please know that we want to help.

The large data dump request is a bit more complicated due to student privacy issues, but it's on our radar.



lead dev
by vlm

I always ask coder/tech types whats their coolest hack / coolest piece of code. Not something else someone else did, not some giant overall project or vague thing like "world peace" just your coolest isolated to one individual "thing" hack. Something they did personally not hired someone else to do, or something their boss did. Maybe in your LOB its an amazing caching technique, or an astounding way to compress video or whatever. Or some astounding workflow thingy. A short story just a paragraph no more. The kind of thing a /. audience would respond with "cool!" when they read it.

Kamens:While I can't promise "amazing" or "astounding" I can at least make you cringe. A couple years ago we had to take Khan Academy down for maintenance. Was gonna take a couple hours. We put up a cutesy little "Shhhh...we're studying!" page to let users know we'd be back soon.

We were Google App Engine novices at the time. The method we used to display that "Shhh...we're studying!" page did something we didn't expect: it returned a caching header that told all downstream clients to cache the page. For 365 days. For _all of our URLs_. And this was _entirely_ our fault (not App Engine's).

Every server or browser between us and our users was now allowed to return "Shhh...we're studying!" for every Khan Academy URL without ever asking us for new content. Our users were gonna sit there, smashing reload, and seeing "Shhh...we're studying!" for a freaking _year_. And our servers would never even see their requests to get a chance to fix the problem. Thankfully, the App Engine team came through in the middle of the night and gave us a way to clear the cache for exactly two URLs on all of their frontend servers, where most of this problematic caching was happening. We chose the homepage URL, www.khanacademy.org, and (here's where the hack comes in), the URL of javascript file that all of our pages, including the static "Shhhh...we're studying!" page, happened to be referencing. Something like khanacademy.org/jquery.js. We replaced that javascript file with a single line that redirected users to a new subdomain we'd set up at www2.khanacademy.org. The www2 URLs weren't cached all over the entire internet, so kids could start learning again!

Once the disaster died down we switched back to www.khanacademy.org and modified our URLs in a different way to avoid any remaining caches. Surprisingly, our traffic didn't take a hit and everything recovered nicely. But we wondered for about a year if anybody was still seeing that "Shhh...we're studying!" page.



Internships
by Niris

As someone who is currently a senior in computer science and looking for summer internships, what is it that Khan Academy developers look for in perspective interns? I've looked over the blog posts from some of the past interns, and their projects all seem pretty amazing. Is it possible for someone who doesn't have a fair amount of professional level experience to jump in to the internship program with Khan Academy? Disclaimer: I currently have an application in for the internship program, hence my curiosity :)

Kamens:Side projects. Blogs. Having built or written things that others find useful. Being passionate enough to find us and ask interview questions on slashdot.

A past filled with creating value will go a long, long way. Rooting for you.



Jude the Obscure
by Quirkz

Discussions about online learning tend to remind me of the book Jude the Obscure, by Thomas Hardy. It's been a couple of decades, but from what I remember it's the tragic story of a poor working man who dreams of pursuing education/knowledge but who can only barely scrape by with the essentials and can rarely afford even the occasional book. Do institutions like Khan Academy mostly or completely erase that scenario in the modern day? Would a modern Jude have been able to educate and better himself? Are there other obstacles that replace the cost as a barrier to taking this free learning and finding advancement or satisfaction?

Kamens:Ever read The Diamond Age? We give a copy to all interns on their first day. Our long-term sci-fi dream is to remove exactly these obstacles. If we can get one small step closer to The Young Lady's Illustrated Primer (sounds like it would've helped this Jude)...well, that's a dream.

Zothecula writes "Taking a two-month-old in for vaccination shots and watching them get stuck with six needles in rapid succession can be painful for child and parent alike. If the work of an MIT team of researchers pans out, those needles may be thing of the past thanks to a new dissolvable polymer film that allows the vaccination needle to be replaced with a patch. This development will not only make vaccinations less harrowing, but also allow for developing and delivering vaccines for diseases too dangerous for conventional techniques." The patch was designed with delivering DNA-based vaccines in mind. Thus far efforts to use DNA to generate more robust and safe vaccines has failed thanks to the immune system destroying them; the polymer film embeds itself in your skin and slowly dissolves, protecting the DNA in the process.

Not much, it would appear. LaMacchia, an apparent student of Abelson's whose defense team included Beckman, was indicted in 1994 and charged with the 'piracy of an estimated million dollars' in business and entertainment computer software after MIT gave LaMacchia up to the FBI. LaMacchia eventually walked from the charges, thanks to what became known as the LaMacchia Loophole, which lawmakers took pains to close. 'MIT collaborated with the FBI to wreck LaMacchia's life,' defense attorney Harvey Silverglate charged in 1995 after a judge dismissed the case.

sciencehabit writes "A purported conflict between the century-old theory of classical electrodynamics and Einstein's theory of special relativity doesn't exist, a chorus of physicists says. Last April, an electrical engineer claimed that the equation that determines the force exerted on an electrically charged particle by electric and magnetic fields — the Lorentz force law — clashes with relativity, the theory that centers on how observers moving at a constant speed relative to one another will view the same events. To prove it, he concocted a simple 'thought experiment' in which the Lorentz force law seemed to lead to a paradox. Now, four physicists independently say that they have resolved the paradox."

theodp writes "Explaining that it believes 'the most important questions are the ones that will come from the MIT community,' MIT announced that it won't be accepting questions from outsiders for its President-ordered 'review' of the events that preceded the suicide of Aaron Swartz. But if you feel the 25 questions asked thus far don't cover all the bases, how about posting additional ones in the comments where MIT'ers can see them and perhaps repost to the MIT site some that they feel deserve answers? Do it soon — MIT President Rafael Reif will be returning any day now from Davos, where he sat on a panel with Bill Gates, who coincidentally once found himself in hot water over unauthorized computer access. 'They weren't sure how mad they should be about it,' Gates explained in a 2010 interview, 'because we hadn't really caused any damage, but it wasn't a good thing. Computer hacking was literally just being invented at the time, and so fortunately we got off with a bit of a warning.'" Related: text has been published of public domain advocate Carl Malamud's remarks at Swartz's memorial. Quoting: "Aaron wasn't a lone wolf, he was part of an army, and I had the honor of serving with him for a decade. Aaron was part of an army of citizens that believes democracy only works when the citizenry are informed, when we know about our rights—and our obligations."
