What Facebook knows about us?

Today I read very worrysome tweet from Dylan McKay that he found out that once he installed Facebook on his Android Smartphone Facebook is logging all his contacts, phone calls, time he talked etc private info which has nothing to do with Facebook service. This may be used for industrial espionage, who did you call and consulted before make a deal, or for target marketing – you called doctor, let’s show some medical service ads in your Facebook stream.

So I decided to see what Facebook knows about Olimex. In Settings menu you have Link Download a copy of your Facebook data. I downloaded it and as expected there is log of all pictures, posts, messages sent via the Facebook messenger, no matter if you deleted them or not.

Fortunately Facebook is not interested to log the phone calls for user accounts from Bulgaria as there is none such info in the downloaded zip, but there is *complete* list of all my phone and e-mail contacts! I changed recently my phone and my current phone contact list is shorter than this one logged in Facebook. There are contacts which I deleted long time ago, so once something is add to this contact list it’s not deleted even if you delete it from your phone.

The smartphones now are the perfect spy tools. This exceeds George Orwell’s imagination for what is possible in the future. We personally carry with us our own spy devices voluntarily.

Linux-Rockchip.info Wiki site is created to collect info about Rockchip SoCs


Last week I blogged about the amazing RK3188 Quad core processor from Rockchip https://olimex.wordpress.com/2013/07/08/rk3188-usd-12-quad-core-cortex-a9-running-at-1-8ghz/

The site www.linux-rockchip.info was created to collect all available info for Rockchip devices in a form of Wiki.

Rockchip is way more closed than Allwinner, they do not understand open source and Linux and are in the same state of mind like Allwinner 2 years ago. With lot of push from Open Source evangelists Allwinner slowly opened and now even released some of their closed source code for the bootloader and flash controller.

Rockchip is still in the stone age, they require NDA and $5000 to send you SDK for building Android images which even have no sources inside but binary blobs.

All Rockchip kernel and Linux support so far is done by group of hackers who reverse engineer their code for fun and they have already significant success.

The reason Linux-Rockchip.info was created is to have place where to collect all info for Rockchip like Linux-Sunxi.org is doing for Allwinner SoCs.
