Perceptual Ad Blocker blocks ads by graphic elements, not by code

A few guys from Princeton and Stanford universities have worked together and create Perceptual Ad Blocker, a different piece of adblocking software, that detects ads by the graphical elements, the content dimensions and the sponsored words. The software does not hide the ads completely, but covers them and displays the “This is an ad” text.

As you may know, the classical adblocking software analyzes the source code of pages to identify the ads, while Perceptual Ad blocker does things in a different way. It has been initially released to block the annoying Facebook Ads, after the website has started to integrate the ads in the content better and better, and the classical ad blockers could not block them.

Another good thing about Perceptual Adblock is that it is not discovered by the websites, being an ideal solution for that kind of websites that do not offer the content if you do not whitelist them in your adblocker. It has been tested on 50 websites that usually detect adblockers, but it has been invisible.

For now, Perceptual Ad Blocker is just a proof of concept, available only for Google Chrome, as an extension. For more information, see this thread on the MMO-Champion forum.


According to Avast, Windows XP has more users than Windows Vista and 8 combined

Despite Microsoft’s aggressive marketing strategy created to persuade users to upgrade to Windows 10, Windows 7 is still leading the market. The folks from Avast have published some stats about the global Windows usage for the first quarter of 2017 and revealed some interesting facts.

56 million computers use Avast on Windows 7, this representing 48.35% of the market share. Windows 7 is followed by Windows 10, which is installed on 35 million devices running Avast software and Windows 8.1, which is installed on 12.7 million systems running Avast, representing about 10.96% of the market.

The big surprise is Windows XP, which has a market popularity bigger than Windows Vista and Windows 8 combined. According to the same numbers, Windows XP is still running on 6.5 million computers using Avast software (about 5.64%), while Windows 8 is running only on 2.51% of the computers having Avast installd, and Vista running on 2.08%. Speaking of Vista, it will reach end of life (EOL) next month, so if you still have it on your system it is advised either upgrade or switch to Linux.

Windows XP is still used due to the fact that it ideal for computers with old hardware and can run specific programs built on old technology that are not compatible with newer Windows systems.
