Here is a breakdown of R, Octave and Python, and how analysts can rely on open-source software and online learning resources to bring data-mining capabilities into their companies. The article breaks down which of the three is easiest to use, which do well with visualizations, which handle big data the best, etc. The lack of a budget shouldn't prevent you from experiencing all the benefits of a top-shelf data analysis package, and each of these options brings its own set of strengths while being much cheaper to implement than the typical proprietary solutions.

First time accepted submitter Shalmendo writes "My client needs to monitor traffic on his LAN, particularly going out to the internet. This will include websites like Facebook, Myspace, and similar, including from mobile devices. So far, based on the network education I have, I've concluded that it might be best to get a tap (And some kind of recording system with wireshark, probably a mini-barebone), or replace the existing Linksys router with a custom built mini barebone system with linux routing software and appropriate storage capacity etc to record traffic internally. (either way it looks like I will need to put together a mini barebone system for some purpose) My client is trying to protect his family from scammers and other unsavory types, and isn't savvy in this matter, so i'm doing it for him. What I need is a way to record the traffic at a singular point, like modem/router areas, or similar, and a way to scrape out Facebook, Myspace, and other messages. It also appears that the client's family is using iPhones and some game called 'words' which has message capability. Is it possible to scrape messages out of that game's packets, or are they obfuscated? Can I write a script? What software would you recommend? Linux routing OS? Can we sniff packets and drop them on the internal hard drive? or would a tap be better? How do I analyze and sort the data afterwards? my client needs easily read evidence (Such as text or screenshots) he can use as proof in discussion with his family to try and intercede in any potentially harmful transactions. In other words, how can I Achieve this goal? I have basic and medium training in computer networking, so I can make my own cables and such, but I've never worked on this exact kind of project before, and thought it might be better to query slashdot instead of do my own research from scratch. After days of discussion with the client, it's not plausible to put monitoring software in the devices on the network (due to legal issues and a few other factors), so I concluded a network tap or other device would be the best way to capture and study what's going on."

jfruh writes "Adscend Media, which has been making up to $20M a year from so-called 'likejacking' spam on Facebook, has reached an agreement with the Attorney General of Washington to stop those activities and pay $100,000 in court costs. Among other nefarious techniques, Adscend would overlay Facebook 'like' buttons with provocative photos to spread links to ads from which Adscend would earn referral fees. Adscend also settled out of court with Facebook for an undisclosed amount."

Chuq writes "Tasmanian Liberal candidate for Bass, Andrew Nikolic, was the subject of a satirical article by NewExaminer on Facebook. Nikolic didn't like it, which is understandable. However he then went to considerable lengths to identify the people who liked the article, find out their employers (via their Facebook profiles) and 'name and shame' them on a follow-up post on his own page. Andrew Nikolic has a history of poorly handling conflicting views on his Facebook page, resulting in creation of another page, 'Andrew Nikolic blocked me.'"

bhagwad writes "Apparently Robert Scoble tried to post a long comment on Facebook only to have a message pop up saying 'This comment seems irrelevant or inappropriate and can't be posted. To avoid having your comments blocked, please make sure they contribute to the post in a positive way.' If true, this is huge. For one the self-moderating system of comments has always been the rule so far. And with countries like India rooting for the pre-screening of content and comments, is Facebook thinking of caving into these demands?" Facebook says there's a more innocuous explanation: namely, that the comment triggered a spam filter.

An anonymous reader writes "While the celebs are already charging big money for their Tweets, an Aussie startup is ranking everyday people and turning them into product salespeople. After a successful start Down Under they have now hit Silicon Valley, but will Americans embrace selling to their friends?" From the article: "In a nutshell, individuals sign up to the Social Loot website and are assigned companies to promote to their circle of online friends. They are then paid on a sliding scale based on the amount of traffic their posts generate, and the quality of referrals and number of resulting sales. This is tracked by a code embedded in the links promoted by Social Loot’s spruikers."

wytcld writes "Sending an individually-written e-mail to my state senator resulted in an automated response saying that since she receives hundreds of e-mails a day, there might be no personal response, but please don't take that to mean she hasn't read my e-mail. So I contacted her again suggesting that was a pretty poor answer. Most of the e-mails she receives are mass mailings coordinated by various interest group websites. Why doesn't she put those to the side, I asked, and prioritize response to individual e-mails from constituents who've taken the time to actually write? Her response? She often can't tell the difference at first, so spends time drafting responses to the first instances of group e-mail spam, and gets diverted from responding to those who really write her. Are there tools out there which a politician can use to identify the incoming group-think blasts and put them to to side? It's easy enough to imagine sorting by repeated content or headers, if I ran the mail server, but I'm looking for packages already out there that a state-level representative, with no staff to speak of, might use to cut through the mess and prioritize communication with constituents who care enough about an issue to draft their own thoughts."

An anonymous reader writes "Rachel Marone has been a victim of cyberstalking for over 10 years. In 2011, she had a project on Kickstarter shut down because of the high volume of spam posted by the stalker in the comment section of the project. Recently, Marone's manager spoke to Kickstarter again to see how she could avoid having a new project banned if the cyberstalker showed up again. They replied, 'If there is any chance that Rachel will receive spam from a stalker on her project, she should not create one. We simply cannot allow a project to become a forum for rampant spam, as her past project became. If this happens again, we will need to discard the project and permanently suspend Rachel's account.' On her website, Marone sums up the situation thus: 'I am being told that I cannot crowdfund because I am a stalking victim. ... With so many women being stalking targets this does not seem reasonable to me.'"

An anonymous reader writes, quoting Network World: "As with any platform that sees a meteoric rise in popularity, it's only a matter of time before spammers throw their hats in the ring and try and exploit the masses for financial gain and other sinister purposes. As the relatively new kid on the block, Twitter is still busying itself trying to tackle and ultimately prevent spammers from destroying the user experience. While Twitter's previous efforts centered exclusively on engineering-based solutions, the company today announced that they are also pursuing legal avenues to fend off spammers." From the Twitter blog: "With this suit, we’re going straight to the source. By shutting down tool providers, we will prevent other spammers from having these services at their disposal. Further, we hope the suit acts as a deterrent to other spammers, demonstrating the strength of our commitment to keep them off Twitter."

Orome1 writes "Industry and government efforts have dealt a significant blow to spam, according to a Commtouch report that is compiled based on an analysis of more than 10 billion transactions handled on a daily basis. The sustained decrease in spam over the last year can be attributed to many factors, including: Botnet takedowns, increased prosecution of spammers and the source industries such as fake pharmaceuticals and replicas. However, spam is still four times the level of legitimate email and cybercriminals are increasing their revenues from other avenues, such as banking fraud malware."

RemyBR writes with an excerpt from an article at El Reg: "Microsoft has confirmed that users of its instant messaging app will not be able to send each other links to popular torrent site The Pirate Bay, citing malware fears. 'We block instant messages if they contain malicious or spam URLs based on intelligence algorithms, third-party sources, and/or user complaints. Pirate Bay URLs were flagged by one or more of these and were consequently blocked,' Redmond told The Register in an emailed statement."

zacharye writes "A new subscription service allows potential gadget owners to test out new devices like Apple's new iPad tablet before committing to a purchase. YBUY, which bills itself as a try-before-you-buy online subscription service, charges users a flat monthly fee of $24.95 for access to a wide range of consumer electronics as well as home and kitchen gadgets. Users can choose one device at a time from YBUY's catalog and trial the gadget for up to 30 days before returning it. Beginning in April, the company's inventory will also include Apple's new iPad."

itwbennett writes "If you drew the short straw among your Minecraft-playing friends and ended up running the game server, this news is for you. A YCombinator-funded startup called Minefold will handle all the server admin tasks for just $5 a month. 'Minefold isn't the first firm to offer servers dedicated to game hosting (see for example gameservers.com) but as far as I know they're the first to structure things so each player pays his own way,' writes Peter Smith. 'In other words, if I want to set up a Call of Duty 4 server at Gameservers I can, but it'll cost me (for example) $15.95/month for a 16 player server. So I pay Gameservers and I get my buddies all to send me a few bucks to defray the costs. It's a messy system. Using the Minefold model, everyone would pay $5/month to play wherever they want. On my server today, on someone else's server tomorrow and on their own server the day after that.'"

smitty777 writes "An Australian woman who was being used by a group of Nigerian scam artists stole over $33,000 from the group who employed her. Her bank account was being used to funnel the cash from a dodgy internet car sales website. Irony aside, it makes one wonder how these folks ever got the nerve to go to the police with this matter. Those of you wondering, this article offers some answers to the question of why so many of these scams originate from this area."

An anonymous reader writes "Paul Tyma, creator of Mailinator, writes about a greedy algorithm to analyze the huge amount of email Mailinator receives and finds ways to reduce its memory footprint by 90%. Quoting: 'I grabbed a few hundred megs of the Mailinator stream and ran it through several compressors. Mostly just stuff I had on hand 7z, bzip, gzip, etc. Venerable zip reduced the file by 63%. Not bad. Then I tried the LZMA/2 algorithm (7z) which got it down by 85%! Well. OK! Article is over! Everyone out! 85% is good enough. Actually — there were two problems with that result. One was that, LZMA, like many compression algorithms build their dictionary based on a fixed dataset. As it compresses it builds a dictionary of common sequences and improves and uses that dictionary to compress everything thereafter. That works great on static files — but Mailinator is not a static file. Its a big, honking, several gigabyte cache of ever changing email. If I compressed a million emails, and then some user wanted to read email #502,922 — I'd have to "seek" through the preceding half-million or so to build the dictionary in order to decompress it. That's probably not feasible.'"

Barence writes "Microsoft claims an "independent" report proves it has the best spam protection in the industry — an argument deconstructed by PC Pro. 'Our own internal metrics, customer feedback, and even a recent third-party report confirms that no mail service offers better protection than Hotmail,' Microsoft's Dick Craddock wrote in a Windows Live blog post earlier this week."

Bennett Haselton is back with a thought provoking essay about not just an incident of Internet censorship on an American university campus, but a proposed method of propagating news, so that relevant stories aren't buried as easily by chance or time. Bennett writes: "The real scandal in the story of Arizona State University blocking students' access to the Change.org website, is not just that it happened, but that the block persisted for two months without being mentioned in the media. As a card-carrying member of the 'outrage grapevine,' I surely think we need a way to respond faster." Read on for the rest.

angry tapir writes "A botnet that was crippled by Microsoft and Kaspersky Lab last September is spamming once again and experts have no recourse to stop it. The Kelihos botnet only infected 45,000 or so computers but managed to send out nearly 4 billion spam messages a day, promoting, among other things, pornography, illegal pharmaceuticals and stock scams. But it was temporarily corralled last September after researchers used various technical means to get the 45,000 or so infected computers to communicate with a "sinkhole," or a computer they controlled."
