Google, Yahoo and Microsoft search engine brain damage

These companies (Google, Yahoo, Microsoft and others) let the user to rank the result of search, but I think the way they uses is completely “brain damage”.

When you do a search on Google for example it will list a number of sites and the phrase in this site with texts related to your searched words. For each result you have the “Promote” and “Remove” button, but how can I promote it if I didn’t read the problem content of that site?

I think a better idea could be using a footnote (obviously at bottom of page) of visited web site where the user could to define your opinion. Nobody like page headers with Ads or anything, but I think using this pool at bottom of page will not bother.

Just my 2 cents, I hope someone from these companies see this comment and think about this idea.

GTK Application to see webcam image

I developed a GTK Application to see webcam images based on Mauro Chebab’s v4l2grab. It is working fine on my embedded system ARM9.

I compiled it this way:

LTIB> gcc gtkwc.c -o gtkwc -I../../../rootfs/usr/include/gtk-2.0 -I../../../rootfs/usr/include/cairo -I../../../rootfs/usr/include/glib-2.0 -I../../../rootfs/usr/lib/glib-2.0/include -I../../../rootfs/usr/include/pango-1.0 -I../../../rootfs/usr/lib/gtk-2.0/include -I../../../rootfs/usr/include/atk-1.0 -lgtk-x11-2.0 -lv4l2

Or just:

LTIB> gcc v4l2grab.c -o gtk_v4l `pkg-config –libs –cflags gtk+-2.0` -lv4l2

Thank you Douglas Landgraf for suggesting me to use v4l2grab

Testing Logitech Quickcam on Embedded System

I am testing “Logitech Quickcam for Notebooks Pro” on an embedded board (ARM9 processor).
Camera ID: 046d:08b1 Logitech, Inc.

This camera is supported by “USB Philips Cameras” (symbol USB_PWC).

After loading the “pwc” module I was getting this error message:

pwc: isoc_init() submit_urb 0 failed with error -38

To solve it I selected “Full speed ISO transactions” (symbol USB_EHCI_SPLIT_ISO)
