Realtime noise-removal with PulseAudio? [linux]

Tips & Tricks ,
Realtime noise-removal with PulseAudio? [linux]

I started reading a lot about PulseAudio and "hidden" options it had so I could find one that was similar to this question. The one I found was the noise-cancellation module, which is one that dramatically lowers any static noise on the microphone and even A LOT of the background noise, basically giving you the benefit of only recording your own voice with excellent quality (For audio recording for example). To do this follow this steps:
  1. sudo nano /etc/pulse/default.pa
  2. Add the following line anywhere on the file, but I recommend almost at the end where you will find a comment about Echo Cancellation stuff (~line 140):
    load-module module-echo-cancel
  3. Reload PulseAudio (pulseaudio -k) or simply restart the computer. You should be able to select the new Noise Cancellation option from the Input Device Section:

#2. Limit your search to recently uploaded videos
oprah winfrey, this week
This will only show recent videos related to Oprah that have been uploaded to YouTube in the past week. You may also use “today” or “this month” to limit your search to videos that were uploaded in the past month.
#3. Find only official videos, no fan material please
never say never, partner
If you are looking for the ‘official’ Justin Bieber track and don’t want to see any parodies or fan material in the search results, add the word ‘partner’ to your search query.



#4. Find movies on YouTube

One Line CSS Magic - CSS Tips and Tricks

No need to mention CSS is awesome. Here one line css magic. Its pure beauty of CSS that gives life to the website and makes it lively. Yes, it’s not simple to write CSS for newbie and even professionals sometimes gets stuck because of cross browser issues. Sometimes, One line in CSS can be more than a magic providing solutions. I reviewed some of the CSS files and came up with some one line CSS.
Below are list of one line CSS. One line CSS mentioned below may or may validate web standards and web accessibility rules.

1. Set default margin and padding to all elements
* {margin: 0; padding: 0}
Every element that have not assigned margin or padding will have default value of above.
Some CSS designers argue that this is not necessary at all because all CSS element at the end will have their assigned value.

2. Set image border to zero
img { border: 0; }
a img { border: 0; }
This can be used to prevent any linked images from displaying borders.

3. Remove Firefox’s link border
a:active, a:focus { outline: 0; }
This removes dotted outline from focused or active links on firefox.

4. Scrolling Render IE
html { background : url(null) fixed no-repeat; }
5. Prevent line breaks in links, over sized content to break
a{ white-space:nowrap;}
element { overflow:hidden; }
This trick prevents line breaks on links.
6. Centering block elements horizontally
element { margin:0 auto; }
This one line CSS horizontally centers a block level element.
For IE less than 7, following line should be added though.
element { text-align: center; }
7. Show Firefox scrollbar
html{ overflow:-moz-scrollbars-vertical; }
8. Remove textarea scrollbar in IE


textarea{ overflow:auto; }
