By default, in recent Fedora versions, when you attempt to import an MP3 file in Audacity, it returns this error:
“This version of Audacity was not compiled with MP3 files support.”
To resolve this issue first remove "audacity" package:
$ sudo yum remove audacity
Next – add RPMFusion repository:
$ sudo rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
$ sudo rpm -ivh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
And the last step – install "audacity-freeworld" package:
$ sudo yum install audacity-freeworld
Done and done!
Just use this magic string:
$ mplayer tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0:fps=30:outfmt=yuy2 -vo caca
This will render webcam video in color ASCII. For black and white version use -vo aa option.
Of course, mplayer package should be installed.
To add a favicon to your site or blog do the following (tried on Linux):
- Create an image in GIMP 16×16 or 32×32 in size, number of colors – below 16
- Save it as favicon.ppm
- Convert it to ico using this command:
1
| ppmtowinicon -output favicon.ico favicon.ppm |
- If previos step doesn’t work – install netpbm and netpbm-tools packages:
1
| $ sudo yum install netpbm netpbm-tools |
- Copy favicon.ico to your website document root directory
- Add the following lines to your index.html or header file:
1
2
| <link href=’http://www.URL.com/favicon.ico’ rel=’shortcut icon’/>
<link href=’http://www.URL.com/favicon.ico’ rel=’icon’/> |
Seems like you need to install ACPI service:
1
2
3
| yum -y install acpid
systemctl enable acpid.service
systemctl start acpid.service |
Open Terminal window and type:
sudo gpointing-device-settings
Then on General tab click “Disable tapping and scrolling”
