Recovering lost data

Brian Mahoney at maximum PC (http://www.maximumpc.com/) writes a useful tutorial at Gizmodo on different methods to recover lost datas (full article at http://gizmodo.com/5741708/how-to-recover-your-data-mostly-free-and-easy).

I think that regular back up is the only way to sleep well at night, but, of course real time back up is quite time and resource consuming, so that some ways to recover file might become quite handy.

Worth a read.


Finagles laws (2,3 and 4)

Second Law: No matter what the anticipated result, there will always be someone eager to (a) misinterpret it, (b) fake it, or (c ) believe it happened according to his own pet theory.

Third Law: In any collection of data, the figure most obviously correct, beyond all need of checking, is the mistake

Fourth Law: Once a job is fouled up, anything done to improve it only makes it worse.


A spy toolkit for iPhone

Michael Trei at Dvice (http://dvice.com/archives/author/michael_trei) reports that Brickhouse security markets an “[…] innocent looking USB drive has only one purpose, to download and copy most types of data stored on an iPhone. That means everything including your text messages, voice memos, photos, GPS tracking info, and web searches can be copied quickly be anyone who gets access to your phone for a few minutes […]”. The price is $199 and is available at the moment for iOS3, with iOS4 support coming in september (full article at http://dvice.com/archives/2010/08/spy-stick-lets.php, manufacturer site at http://www.brickhousesecurity.com/iphone-spy-data-recovery-stick.html).

While I don’t endorse neither support the use of such a device, I’m curious about it and ask how can Apple have left such a flaw in security. And we were discussing for antenna problems… 🙂

Corporations and Facebook datas

Dan Nosowitz at Fast Company reports a Gizmodo news that says “[…] The data collected was public, of course–all of these corporations could have just found this data on Google. But after white hat hacker (the good kind, if your definition of “good” is malleable) Ron Bowles collected all of this public data and smushed it into one massive file, it may have sparked an interest that wouldn’t have existed otherwise. Sure, these companies could have found this data elsewhere, at any time–but they likely didn’t. […] [The list of companies, reported by Gizmodo is the one that follows]:

A.C. Nielsen; Agilent Technologies; Apple; AT&T, possibly Macrovision; Baker & McKenzie; BBC; Bertelsmann Media; Boeing; Church of Scientology; Cisco Systems; Cox Enterprises; Davis Polk & Wardwell; Deutsche Telekom; Disney; Duracell; Ernst & Young; Fujitsu; Goldman Sachs; Halliburton; HBO & Company; Hilton Hospitality; Hitachi; HP; IBM; Intel; Intuit; Levi Strauss & Co.; Lockheed-Martin Corp; Lucasfilm; Lucent Technologies; Matsushita Electric Industrial Co; Mcafee; MetLife; Mitsubishi; Motorola; Northrop Grumman; Novell; Nvidia; O’Melveny & Myers; Oracle Corp; Pepsi Cola; Procter and Gamble; Random House; Raytheon; Road Runner RRWE; Seagate; Sega; Siemens AG; Sony Corporation; Sprint; Sun Microsystems; Symantec; The Hague; Time Warner Telecom; Turner Broadcasting System; Ubisoft Entertainment; Unisys; United Nations; Univision; USPS; Viacom; Vodafone; Wells Fargo; Xerox PARC. […]” (full article at http://www.fastcompany.com/1675872/major-companies-are-downloading-the-data-from-those-100-million-public-facebook-profiles).

Again is the proof that Facebook is not safe in any way and  that, generally speaking, the net is not the safest place to keep datas.

Unfortunately, the internet is a big and complex structure, while Facebook is a privately held company without the basic knowledge on how to safely treat datas (either personal or not).

A company holding informations (sensitive or not) of about 1/12 of world population should not be authorized to do so without a clear proof of their capabilities in safeguarding datas.

But this covers about the half of the problem, because the other part is people putting personal datas everywhere without having theknowledge of the uses and availability the datas.

I think that while a serious action should be taken against Facebook (at least to make them think of the problems they are causing), on users consciousness is a battle lost before starting.

Curves and data

Always draw your curves, then plot the data.

Mobile telephone uses

Liz Gannes at Gigaom (http://gigaom.com/author/lizg/), reports some interesting data on mobile phone uses comparing 2009 and today in US(full article at http://gigaom.com/2010/07/07/mobile-video-capture-soars-now-brace-yourself-for-views-and-uploads).

The survey shows an increase of cell phones use quite in all areas, with majority of users texting and taking pictures.

I think that the growth is linked to the wider service available in new OSs and in people being more conscious of functions available.

Facebook (strange) views on privacy

Mathew Ingram at GigaOM (http://gigaom.com/author/mathewingram/) writes an article asking some questions on Facebook privacy, telling that “[…] Communications studies professor Nancy Baym said in an interview that she thinks one of the biggest problems for Facebook is that it has a “fundamentally naive and Utopian” view of what privacy means online, which stems from the fact that the company is run by “a bunch of computer science and engineering undergrads who don’t know anything about human relationships.” […]” (full article at http://gigaom.com/2010/06/01/facebooks-views-on-privacy-are-naive-and-utopian-prof-says).

Facebook views on privacy are “utopian” and are mainly the result of two concurring factors:

  • on one side the utopian concept of anything available to everyone, that underlies the concepts of responsability in charging datas and using them. If this assumption was true, we won’t have no spam, frauds,…
  • on the other side Facebook management being non capable of managing what is a real complex architecture on IT POV. As I said other times, if you consider for a moment the risk that “maliciuos” people are around us trying to do something strange with our datas, as the owner/manager of Facebook you have the due to leave apart thoughts of freedom and equality and make barriers to defend datas given to you.

Datas, errors and mistakes

In any collection of data, the figure most obviously correct, beyond all need of checking, is the mistake.


Social networks and money

Steven Campbell at Makeusof.com writes an article on methods used by social networks to make money (full story at http://www.makeuseof.com/tag/how-do-social-networks-make-money-case-wondering/).

Monetizing a social network is not easy in the short term. Especially if you think that a social netowrk either is a breakthrough or lives short.

So owners need to find real smart ways to transform ideas to money in the short while.

The methods described are:

  • Venture capital (yes is a startup funding, but can be a lot of money. The real difficult thing in this is to make a real solid business plan)
  • Advertising and e-commerce (this is where most of the money is made and that doesn’t require too much effort)
  • Offering premium options (if you like the basic service, why don’t upgrade to richer features?)
  • Creative products and promotions (where companies owning social networks need to be creative and try innovative solutions)
  • Data monetization (means selling personal datas and recorded behaviours for marketing pourposes)

Experiments and data

An experiment may be considered successful if no more than half the data must be discarded to agree with the theory.
