Google Chrome, internet

Why does Chrome have so many open processes?


Use the Google Chrome Task Manager you can get details about a specific process running in the Google Chrome web browser, or force a misbehaving tab or application to close.

SHIFT + ESC – Google Chrome Task Manager.

Chrome puts web apps and plug-ins in separate processes from the browser itself. This means that a rendering engine crash in one web app won’t affect the browser or other web apps.

It means the OS can run web apps in parallel to increase their responsiveness, and it means the browser itself won’t lock up if a particular web app or plug-in stops responding. It also means we can run the rendering engine processes in a restrictive sandbox that helps limit the damage if an exploit does occur.

Nvidia, tecnical problems

Nvidia Optimus and media players forced on integrated card

Just another Nvidia Optimus problem… It is not allow to switch the preferred card for HD video players. There are some applications in control panel settings that have “preferred graphics card” option greyed out with integrated card.

The problem is magically solved by renaming a exe file of the player app.

VVVV. Writer (EX9.Texture) save with Alpha

  • set the backgroung color of the Renderer node to alpha = 0
  • explore hidden pins of the Renderer (with herr Inspector ‘Ctrl+I’) and select any format with an A in it, for example A8R8G8B8 (A 32-bit ARGB pixel format, with alpha, that uses 8 bits per channel. A for alpha)
  • do the same for the DX9.Texture node. ‘Format’ = A8R8G8B8
  • choose a format that supports transparency (PNG, TGA or DDS)
