TinEye – a reverse image search engine

April 30th, 2010

TinEye Logo You know how search works – you open your favorite search engine, type a keyword or two, and there – a list of thousands of pages, containing info about your topic of interest. There even is an image search – you go to Google images and there again – hundreds of images, corresponding (better or worse) to the keywords you entered. But what if you do not know what you’re looking for? What if you have an image of a painting and want to know who painted it? Or a photograph of a place, you want to know where?

TinEye is the “reverse image search engine” you need – you just have to upload your image (or give the URL-address, if it is published on a webpage), and you will get results from other pages, containing the same image. It gives you the chance to learn what it is, since you will probbably get pages, containing info about it. Here is how it works:

It is also a good tool to see who is using your images 😉

WiDi – Intel wireless display

April 14th, 2010

Intel WiDi Have you already heard about the new WiDi technology? it is the Intel’s wireless display.

It requires a compatible laptop (some of the new Intel Core i7 / i5 / i3 processors, an Intel (Advanced) N wireless adapter, 64-bit Windows 7, and some specialized Intel software), a wireless TV adapter and a TV with a HDMI or composite A/V input. Look for the WiDi icon to find compatible devices.

So far, the announced compatible devices are:


  • Dell Studio 15z
  • Sony VAIO S Series
  • Toshiba Satellite E205

Wireless receiver:

  • NETGEAR Push2TV Adapter for Intel Wireless Display

Here’s how it works:

Invaluable knowledge resources

March 1st, 2010

Books There are numerous sources of knowledge on the Internet. Among the eLearning resources, specialized reading, focus groups, portals, etc., you can find the topic that is of interest to you and spend a lot of hours reading and watching videos on the subject.

I am also very keen on learning new things and gathering knowledge in various spheres of life. So, I was very excited, when several years ago, one of the most prominent universities in the IT sphere – the Massachusetts Institute of Technology (MIT), decided to start an innovative project – to make the courses, taught to MIT students, available online. Since then, many universities have made this step, and as a result, you can now “attend” top universities’ courses from the comfort of your own home, to mix and match content according to your own interests and needs, and to design unique curricula for yourselves.

So here is (hopefully, an ever growing) list of links to the publicly available university courses and other knowledge resources:

Feel free to propose other valuable resources, that belong to the list. Also, be sure to revisit this article, as it is my intention to keep the list updated as I find other valuable resources.
