OS X Lion update accidentally outs user passwords in plain text, stumbles over FileVault

Are you an avid user of OS X’s FileVault encryption and running a recently updated version of Lion? It may be time to consider changing your passwords. According to security researcher David Emry, users who used FileVault prior to upgrading to 10.7.3 may be able to find their password in a system-wide debug log file, stored in plain text outside of the encrypted area. This puts the password at risk of being read by other users or enterprising cyber criminals, Emry explains, and even opens the door for new flaw-specific malware. FileVault 2, on the other hand, seems to be unaffected by the bug. The community doesn’t currently have a way to fight the flaw, so users rushing to change their password now may find it being logged as well. Obviously, we’ll let you all know once we hear back from Apple regarding this matter.

Diamonds Used To Increase Density, Performance of Phase-Change Memory


Lucas123 writes “Researchers at Johns Hopkins University have shown they can increase the density, performance and the durability of phase-change memory (PSM) by using diamonds to change the base alloy material. Instead of using the more typical method of applying heat to the alloy to change its state from amorphous to crystalline, thereby laying down bits in the material, the researchers used pressure from diamond-tipped tools. Using pressure versus heat allowed them to slow down the change in order to produce many varying states allowing more data to be stored on the alloy. ‘This phase-change memory is more stable than the material used in current flash drives. It works 100 times faster and is rewritable millions of times,’ said the study’s lead author, Ming Xu, a doctoral student at the Whiting School of Engineering at Johns Hopkins University. ‘Within about five years, it could also be used to replace hard drives in computers and give them more memory.'”

The Rise of Big Data Apps And The Fall of SaaS

rise_and_fall_03

Editor’s note: This guest column is from Raj De Datta, the CEO and co-founder of BloomReach. Follow @BloomReachInc on Twitter.

With the influx of information flooding the web – 90% of the web having been created in the last two years alone – web businesses are looking for ways to understand and use big data to drive their business. Just as SaaS and the cloud completely revolutionized the way businesses operate, so will Big Data applications (BDAs). BDAs are web-based applications that interpret and use massive amounts of enterprise and web-scale data to deliver more intelligent results for their subscribers. BDAs leverage the best of the cloud; they’re web-hosted, multi-tenant and use Hadoop, noSQL and a range of recommendation and machine learning technologies.

But the real question is – so what? So what if the underlying data structures use Hadoop or noSQL? No CEO of a major business gets excited about a value proposition around more scalable data structures. That’s where BDAs come in. BDAs don’t just repackage your data in a cool interface or offer productivity improvements in data scalability, they harness the world’s data to deliver you a better outcome – like more revenue.

SaaS was a different delivery model for enterprise software: available for immediate sign-up, it dramatically reduced integration costs, enabling try-before-buy, scalability and shared tenancy with meter-driven pricing. Salesforce.com started the cloud revolution by transforming the CRM industry and was quickly followed by the SaaS-ification of every category of enterprise software (Taleo/Successfactors for HR, Netsuite for ERP, Omniture for web analytics). SaaS both increased the market size for business software (by enabling mid-size companies to buy at a lower cost of entry) and delivering a better ROI for bigger businesses. But it did not do one important thing–it didn’t change the functional capabilities of the core application. Salesforce didn’t add CRM features for businesses vis-a-vis Siebel – it simply made it easier to adopt and cheaper to maintain.

Big data on the consumer side of software is well-understood – Google, Amazon.com, Facebook. In a recent keynote speech at Cebit, Amazon CTO Werner Vogels noted that when mistakes have been made, it’s because there isn’t enough data to back up a recommendation. All of these are applications that get stickier, smarter and more valuable as more users and data pour into their core engines. Now, we are seeing the beginning of enterprise BDAs, and they are the future:

  • Linkedin (NASDAQ: LNKD) is a BDA for the recruiting/talent acquisition software market. LinkedIn doesn’t ask you to add your contacts in an isolated contact list, it networks those contacts, connecting users with users and recruiters with key competencies. Every user that joins LinkedIn adds a signal to the LinkedIn BDA stack, enabling the recruiter to harness all their millions of profiles, not just their individual silos. As a result, smaller, specialized recruiters are competing with the biggest executive search agencies with comparable reach.
  • Bazaarvoice (NASDAQ: BV) is a BDA for social sharing. Bazaarvoice collects customer reviews from across the web, then powers multiple websites with that information. The traditional SaaS-based approach to this problem would simply have provided software to accept and publish reviews on individual sites. Instead, Bazaarvoice collects review data from across the web to make sure when you pull up a product on one of its customer websites, the right reviews are presented to you. Bazaarvoice gives all sellers comparable review databases to Amazon.com.
  • Salesforce (NASDAQ: CRM) understands that BDAs are the future of SaaS. When it acquired social listening software company Radian6 and contacts company Jigsaw (now Data.com), Salesforce understood that the powerful application for brands would be aggregating social data points on brands from across the web and networked contact information to salespeople.
  • Our business, BloomReach, is a BDA for marketing, the next $10bn category in software. We could have merely analyzed websites to identify missing relevant content that could drive revenue across search, social and advertising traffic and made workflow and content recommendations to site owners. Instead, we decided to analyze and interpret web-wide demand, build semantic models around web content for a given customer and then dynamically augment websites with the most relevant content for their users. Adobe’s Omniture packages your data in a cool SaaS application to make marketing recommendations for your business. BloomReach analyzes the web’s data and then acts on it to drive more traffic and revenue to our customers.

BDAs are inherently better than their SaaS equivalents because they have all the delivery model benefits of SaaS, plus a network effect in the data being collected. Unique data, put to work for each customer, is an asset that creates network effects over time for both subscribers and for the application provider. These days, there is so much more data outside the enterprise than within it, that the notion of re-packaging an enterprise’s own data for analysis and workflow seems quaint.

BDA companies create value differently than SaaS companies. BDA companies are built by teams of people with a strong background in large-scale systems and machine learning / data mining (like my co-founder Ashutosh Garg). They will also be valued differently than SaaS companies. While both sell into enterprises, BDAs deliver much more value per dollar spent, because each acquired customer adds data to the engine, which in turn improves the service for all its customers. Markets typically value SaaS companies on three basic metrics: Customer Lifetime Value (higher LTV is better), Cost of Customer Acquisition (lower CCA is better) and Rate of Growth (higher is better). Certainly, most SaaS companies have a great growth rate. But BDAs will have higher LTVs (because value/customer is higher and churn will be lower) and lower CCA (because of network effects; consider the CCA for LinkedIn to acquire a new recruiter now, versus five years ago).

The BDA revolution is just beginning. If we were building CRM again, we wouldn’t just track sales force productivity; we’d recommend how you’re doing versus your competitors based on data across the industry. If we were building marketing automation software (Marketo, Eloqua), we wouldn’t just capture and nurture leads generated by our clients, we’d find and attract more leads for them from across the web. If we were building a financial application, it wouldn’t just track the financials of your company, it would compare them to public filings in your category so you could benchmark yourself and act on best practices. Every category of software will have a BDA leader (some may be current SaaS companies that adapt or acquire).

Like anything in technology, the next new thing doesn’t mean the old things go away. Oracle and SAP are still big companies but Salesforce.com is the newest $20 billion behemoth. The new kids on the block will be BDAs.

Hello BDAs, Goodbye SaaS.

First solar-powered boat to circle the world pulls into home port, contemplates next move

It’s been two years since we last heard of the 98-foot-long solar-powered boat, which at the time was gearing up for its big journey around the world. Well, some 19 months and 37,286 miles after setting sail from Monaco, the MS Turanor PlanetSolar has finally made it home. The PlanetSolar broke four Guinness world records along the way, including the all-important “first circumnavigation by solar-powered boat,” and it made stops on six continents to promote solar energy. Oh, and the team fended off Somalian pirates in the process, too. Now that it has a moment to catch its breath and soak up some rays at leisure, the MS Turanor could become any number of things — from the world’s largest solar battery to a “green luxury yacht.” The latter option would certainly befit its chichi home port.

Weaving Blood Vessels


Photo: Cytograft

You’re looking at a “rope” made from braided human parts. No,
it’s not a premise for a new Syfy movie, rather a new tissue engineering
technique by biotech firm Cytograft:

… the biological strands could be used to weave blood vessel
patches and grafts that a patient’s body would readily accept for wound
repair. The process is faster and could be more cost-effective than
other methods of producing biological tissue replacements. […]

Cytograft’s technique draws upon a long history of medical textiles,
which are typically produced with synthetic fibers like polyester. “Creating
textiles is an ancient and powerful technique, and combining it with
biomaterials is exciting because it has so much more versatility than
the sheet method,” says Christopher Breuer, a surgeon, scientist,
and tissue engineer at the Yale School of Medicine. “The notion
of making blood vessels or more complex shapes like heart valves, or
patches for the heart, is much easier to do with fibers,” he says.
“If you can make fibers of any length, then there is no limit to
the size or shape that you can make.”

And that’s a better than any science fiction tale you can weave: Link

The TelePod: A Kinect-Based, 360-Degree Life-Sized Teleconferencing System

0telepod.jpg

Led by professor Roel Vertegaal, a research team at the Human Media Lab of Canada’s Queen’s University has created a fascinating 360-degree display called the Telepod. It consists of a human-being-sized acrylic cylinder, six Microsoft Kinect sensors and a 3D projector, and as you’ll see in the video below, affords the viewer an experience similar to interacting with a hologram. The cylinder displays a live, three-dimensional image of the person with whom you’re interacting, and you can circumnavigate the cylinder to get a completely wraparound view.

The research team foresees at least two applications of the technology. The first, called TeleHuman, is basic teleconferencing. The second application, called BodiPod, could revolutionize the medical industry. It provides the viewer with a “peelable” X-ray scan of the subject’s body, meaning a patient on one continent could receive a diagnosis from a specialist on another (assuming the resolution was high enough). Have a look:

Pirate Bay enjoys 12m extra visitors on day one of court-ordered UK censorship

Several major UK ISPs began blocking requests for The Pirate Bay this week, thanks to a court order coming into effect. The Pirate Bay reports that it saw an extra 12 million visitors on the first day of the block, and is pleased by all the publicity. They offer the following tips for anyone looking to circumvent a national Pirate Bay block. From TorrentFreak:


“Another thing that’s good with the traffic surge is that we now have time to teach even more people how to circumvent Internet censorship,” the insider added…

First off they advise that the most simple solution is to use a VPN, such as iPredator or other similar services that carry no logs.

These VPN providers cost money but there are free solutions too. Companies such as VPNReactor offer a free service that is time limited to around 30 mins per session, but that’s plenty of time for users to get on Pirate Bay and download the torrent files they need. Once users have the torrents in their client, the blocking has been bypassed and even with the VPN turned off, downloads will still complete.

Pirate Bay are also recommending the use of TOR but only for the initial accessing of their website and the downloading of the .torrent files. Torrent clients themselves should never be run over TOR, the system isn’t designed for it and besides, transfers will be pitifully slow. TPB also point to I2P as a further unblocking option.

While the above options will cut straight through any kind of blocking with zero problems, Pirate Bay are also advising people to change their DNS provider. By permanently switching to a DNS offered by the likes of OpenDNS and Google, users of UK ISPs that censor The Pirate Bay purely by DNS will have a free and effective work around.

The UK Pirate Party is offering its own proxy for The Pirate Bay.
