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.

Frequent contributor Bennett Haselton writes: "The distributed-social-networking Diaspora Project recently announced that their software will be released as open source. I don't know if Diaspora specifically will be the Next Big Thing in social networking, but I hope that social networking moves to a decentralized model within the next few years, where anyone can set up and run a hub to administer profiles for themselves and their friends or clients, and where profiles can interact with each other in a distributed fashion instead of on a centralized system like Facebook." Read on for Bennett's thoughts on how that model could work.

Frequent Slashdot contributor Bennett Haselton writes "Tunisia's high court will decide on Wednesday whether to allow censoring of websites containing pornography or 'calls to violence.' It's disappointing that censorship continues in post-revolutionary Tunisia, but it's enough of an improvement over the old regime, that anti-censorship cyber-activism efforts would probably best be spent on helping other countries." Read on for Bennett's analysis.

Michael J. Ross writes "Most computer and web programming books are written entirely by a single author, while the remaining are written by more authors, typically with each one tackling several chapters. The latter approach can suffer from redundant material undetected by editors, and inconsistency in the writing style from one chapter to the next. Yet it offers the significant advantage that the subject matter of each chapter can be presented by an authority on that topic — who can focus on making that explication the best possible, without the burden of completing an entire book. That was one of my first thoughts (and hopes) when hefting the 1112 pages and 4.1 pounds of the Definitive Guide to Drupal 7." Read on for the rest of Michael's review.

GovTechGuy writes "Social Intelligence Corp's online employment screening service, which preserves users' social media profiles and other data for use by potential employers, infringes on consumers' privacy and could be a violation of the law according to Senators Richard Blumenthal (D-CT) and Al Franken (D-MN). The Senators wrote to Social Intelligence Corp on Monday demanding answers to a host of questions about the service and how it collects data."

JR0cket writes "Scribus is an open source desktop publishing tool that helps you create professionally laid out documents, from simple documents to full blown magazines, corporate brochures or even books. Desktop publishing tools are not a replacement for word processors, instead they give you the freedom to create uniquely designed documents and help you manage large sets of text and graphic content. Scribus is similar to Adobe InDesign or Quark Xpress and gives you a wide range of tools to layout content in either print or digital media form. Scribus is pretty easy to get to grips with and has good documentation on the project website. The Scribus 1.3.5 beginners guide is a really handy guide through the workflow of desktop publishing and helps you clearly understand how to create professional looking results." Read below for the rest of JR0ket's review.

Michael J. Ross writes "While it is possible to create a simple website using a base installation of Drupal, the real power of this content management system is achieved through the use of modules, which can be thought of as add-ons that extend the capabilities of Drupal in specific ways — oftentimes in conjunction with other modules. These modules are developed and contributed by PHP programmers who understand how to use one or more of the Drupal application programming interfaces (APIs) to access information stored in a Drupal database, such as content, user profiles, and theme settings. These APIs have changed with Drupal version 7, and thus Drupal coders could benefit from a book that explains how to create Drupal 7 contrib modules." Read on for the rest of Michael's review.

David Taiaroa writes "I was pleased to recieve a review copy of Joomla! Social Networking with JomSocial – Enhance your social networking with JomSocial by Beatrice A. Boateng and Kwasi Boateng. I've worked with many Joomla! extensions, but not with any of the social network options, so I was able to approach this book as someone learning about the topic for the first time."

crimeandpunishment writes "Housewives, college students, and others are working for a website that charges users an hourly rate for their companionship. No, it's not an escort service — at least it's not one 'with benefits.' It's a site called rentafriend.com, that's trying to carve out a niche in the 'everything's available online' business world. The seven-month-old site, patterned after hugely successful sites in Asia, has nearly 2,000 members who pay either a monthly or yearly fee to check out the pictures and profiles of more than 160,000 potential pals." I thought Craigslist had already cornered the market on renting a friend for an hour or two.

An anonymous reader writes "For the last 24 hours, a series of attacks have exploited Facebook's 'Like' feature through a clickjacking vulnerability. Using subjects such as 'This Girl Has An Interesting Way Of Eating A Banana, Check It Out!' hackers have spread an attack that links to web pages that use invisible iFrames to trick users into saying they like the content. Users are presented with a innocent-seeming web page that says 'Click here to continue,' but clicking at any point on the page publishes the same message to their own Facebook page. Security blogger Graham Cluley says that hundreds of thousands of Facebook users have been hit, and offers advice on how to clean up affected Facebook profiles.

VindictivePantz writes "In an interesting graphical view on collaborative development, FlowingData writes: 'GitHub is a large community where coders can collaborate on software development projects. People check code in and out, make edits, etc. Franck Cuny maps this community (with Gephi), based on information in thousands of user profiles.'"

SpuriousLogic passes along this excerpt from the ChiTrib: "The Feds are on Facebook. And MySpace, LinkedIn, and Twitter, too. US law enforcement agents are following the rest of the Internet world into popular social-networking services, going undercover with false online profiles to communicate with suspects and gather private information, according to an internal Justice Department document that offers a tantalizing glimpse of issues related to privacy and crime-fighting. ... The document... makes clear that US agents are already logging on surreptitiously to exchange messages with suspects, identify a target's friends or relatives and browse private information such as postings, personal photographs, and video clips. Among other purposes: Investigators can check suspects' alibis by comparing stories told to police with tweets sent at the same time about their whereabouts. Online photos from a suspicious spending spree... can link suspects or their friends to robberies or burglaries." The FoIA lawsuit was filed by the EFF, which has posted two documents obtained from the action, from the DoJ and Internal Revenue (more will be coming later). The rights group praises the IRS for spelling out limitations and prohibitions on deceptive use of social media by its agents — unlike the DoJ. The US Marshalls and the BATFE could not find any documents related to the FoIA request, so presumably they have no guidelines or prohibitions in this area.

Frequent Slashdot contributor Bennett Haselton writes "A woman sued Yahoo because they wouldn't remove a page created by her ex-boyfriend pretending to be her and soliciting strangers for sex. What would be an effective system for large companies like Yahoo to handle 'impostor' complaints, without getting bogged down by phony complaints and unrelated disputes? This is a harder problem than it seems because of the several possible cases that have to be considered. One possible solution is given here." Read on for Bennett's analysis.

Michael J. Ross writes "Every major content management system (CMS) offers considerable functionality for building Web sites out of the box. But to get the most out of any CMS, its functionality must be extended through the addition of modules, most of which are created by third-party developers. For instance, a given CMS may need to be supplemented by an e-commerce module in order to use that CMS for building an online store. Joomla, one of the most widely used CMSs, is no exception. Web developers interested in creating their own Joomla extensions can read Learning Joomla! 1.5 Extension Development, authored by Joseph LeBlanc." Read below for the rest of Michael's review.

theodp writes "Confirming paranoid high-schoolers' fears, a new Kaplan survey reveals that 10% of admissions officers from prestigious schools said they had peeked at sites like Facebook and MySpace to evaluate college-bound seniors. Of those using the profiles, 38% said it had a 'negative impact' on the applicant. 'Today's application is not just what you send ... but whatever they can Google about you,' said Kaplan's Jeff Olson. At Notre Dame, assistant provost for enrollment Dan Saracino said he and his staff sometimes come across candidates portraying themselves in a less-than-flattering light. 'It's typically inappropriate photos — like holding up a can of beer at a party,' Saracino said. On the other hand, using the Internet to vet someone's character seems overly intrusive to Northwestern's Christopher Watson. 'We consider Facebook and MySpace their personal space,' the dean of undergraduate admissions said. 'It would feel somewhat like an invasion of privacy.'" We recently discussed similar practices from prospective employers.

Ray Lodato writes "Few people would deny that the world has changed significantly since the explosion of the Internet. Our access to immense volumes of data has made our lives both easier and less secure. Hal Abelson, Ken Ledeen, and Harry Lewis have written an intriguing analysis of many of the issues that have erupted due to the ubiquity of digital data, not only on the Internet but elsewhere. Blown to Bits: Your Life, Liberty, and Happiness After the Digital Explosion, published by Addison-Wesley, digs into many of the ramifications of making so much information available to the world at large. As I read through the book, I was alternately fascinated and horrified at what information is available, and how it is being used and abused." Keep reading for the rest of Ray's review.

bart_scriv writes "Facebook is responding to the recent uproar among its users by deploying better privacy protections and control, as well as being more open about future changes. This could be a case study for other social networking sites on how to avoid or deal with similar problems in the future." From the article: "A week before launch, when asked if he was concerned about a privacy backlash, he appeared surprised, saying, 'No, these people share stuff already and they get something out of sharing.' They've shared all right. And Facebook is listening. On Sept. 7, the site is ratcheting up privacy protections--the result of around-the-clock coding. On their privacy settings page, people will be given greater control over what items will or won't be included in news feeds." Relatedly, an anonymous reader writes "A recent Reuters article mentions that Facebook user Igor Hiller, 17, a freshman at University of California, Santa Barbara is organizing a real-world demonstration next Monday at Facebook's downtown Palo Alto headquarters." Read below for Zuckerman's Open Letter to the community.

James Alguire writes "Anyone who's tinkered with LEGOs, Lincoln Logs, or an Erector Set knows the thrill of turning ideas into something tangible. Even if all you've ever done is assemble IKEA furniture, you've felt the satisfaction of turning a collection of parts into a functional object with your own two hands. Makers: All Kinds of People Making Amazing Things In Garages, Basements, and Backyards by Bob Parks, and published by O'Reilly, celebrates the basic human desire to create, to nail together two things that have never been nailed together before and see what it does. While I have worked in construction, built computers from scratch and done my share of soldering, I still felt a sense of wonder after reading about the 76 projects outlined in this book." Read the rest of James's review.

LE UI Guy writes "Reuters is currently running a story regarding LexisNexis being tapped into by identity thieves who accessed up to 32,000 customer profiles. Information hit included names, addresses, Social Security and driver's license numbers. This comes on the heels of rival ChoicePoint being breached for 145,000 profiles last month in a similar case. Better check yourself." Update: 03/10 02:40 GMT by J : ChoicePoint's name corrected (and, it may be more than 145,000, they don't know).

prostoalex writes "It's a young company led by charismatic executive, it shows impressive growth, is located in Silicon Valley and recently filed for Initial Public Offering. Nope, it's not another Google story - New York Times profiles Marc Benioff and Salesforce.com, the company that said No to software applications (mostly Siebel and Oracle apps) and said Yes to hosted CRM solutions (which it hosts on its own servers). Benioff's personal philosophy is interesting as well, as he calls himself compassionate capitalist, believing that corporate philantropy and check-writing should end, but instead the company should allow their employees to dedicate 1% of paid time to volunteer projects in the community." I've used SalesForce for a while now - it's pretty slick. The era of the web-based software package has come.
