Fred skapas inte bara
"Fred skapas inte bara genom att bekämpa och förhindra fysiskt våld. Fredsarbete har också en inre dimension. Vi kan aldrig få fred i den yttre världen så länge vi försummar den inre och så länge vi inte stiftar fred med oss själva, säger Dalai Lama. Världsfred måste växa fram ur inre frid. Det finns ett samband i vad som sker i världen, i det kaos av terror, våld och död som härskar i vår yttre tillvaro och människans inre tankar och känslor."
Audio Recorder’ for Linux: easily record audio streams to mp3
But if you want – nay need – to record something from a radio station, a live web-cast performance or some other ‘audio’ event playing on your computer in Ubuntu how can you do so?
As the name somewhat obviously spells out ‘Audio Recorder’ is a small utility for recording audio. It’s able to capture output from your soundcard, microphone, web browser – even Skype; basically if it plays through your speakers Audio Recorder can record it.
If that boast sounds familiar to you then congrats: you have an excellent memory. ‘Audio Recorder’ is the revamped, renamed version of ‘Audio Rec’ – a traditional GNOME panel applet that offered much of the same. With traditional GNOME applets receiving the toe-end of the developer boot in 11.04, ‘Audio Recorder’ has reincarnated itself as an application proper - complete with obligatory with indicator-applet control.
Recording can automatically triggered by various Linux music players – including Ubuntu default Banshee – as well as with Skype.
The Indicator-Applet used houses four standard options: hide window, stop/start recording, pause recording and quit. The icon used, however, leaves a lot to be desired.
To install via terminal issue the following commands: -
Timer commands can stop, start and pause recording on a given condition.
The general syntax of the commands are
start [at | if | after | on] condition
stop [at | if | after | on] condition
pause [at | if | after | on] condition
The timer field can contain several commands and lines written in English. Press the [Save] button or CNTR + S keys to save the command text. Use the # character to comment out unused lines.
These two timer commands will start recording at 09:30 pm.
start at 09:30 pm
start at 21:30
These commands will stop recording at 9 o'clock in the morning.
stop at 09:00
stop at 09:00 am
The time is valid once a day. The command will fire again next day.
Note. Use the colon ":" to distinguish clock time (hh:mm::ss) from time period or duration.
Notice: If you use the silence word to pause recording, the recording will automatically continue after the condition becomes false (untrue).
Some examples
stop if silence
stop if silence 5s And
pause if silence 5s -24dB
pause if silence In these two cases the recording will pause when the average signal level goes under -24dB (7%) for 5 seconds time. The recording will automatically resume when the signal level rises over -24dB (ca. over 7%).
Examples
start if sound
start if sound 4s
start if voice 3 sec 10%
start if audio -20dB
Notice: If you use the sound (voice or audio) words to start recording, the recording will automatically pause temporarily when the signal level drops under the given level value.
Click the level-bar to show/hide the current % or decibel (dB) value.
For example this will stop recording when the file size reaches 500 KB.
stop if 500 kB
pause if 0.5MB
This will stop recording after 2GB or 12:00 pm.
stop after 2 GB | 12 pm
Eg. this command will stop recording after 1 hour 20 minutes and 15 seconds.
stop after 1h 20m 15s
This will start recording after 22 minutes.
start after 22min
And this will pause recording after 30 minutes or 20 MB.
pause after 30 minutes | 20 mb
You can abbreviate the word hour with h, minutes with m or min, and seconds with s or sec.
For example, this will stop recording after 20 minutes or when the file size exceeds 1GB or if there is no input (the line is empty, silent) in 5 seconds time.
stop after 20 min | 1GB | silence 5s
Another example.
start if sound 6% | 10:00 pm
This command has no effect.
# stop after 800 MB | 20:00:00
This example will start the program from a command line. Start a terminal window from the desktop's main menu and type
audio-recorder --debug-signal
or
audio-recorder -d
Then activate the timer and study the "Avg.rms" value. It may help you to set correct level value for the silence and sound|voice|audio commands.
Notice: You must activate the timer, and use one of silence, sound, voice or audio commands to see the level values.
Valid commands are: status, start, stop, pause, show, hide and quit.
Some examples:
audio-recorder --command start
audio-recorder --command start,hide
audio-recorder --command hide
audio-recorder --command stop
audio-recorder --command stop,hide
audio-recorder --command quit
The status command returns one of these strings: 'not running', 'on', 'off' or 'paused'.
audio-recorder --command status
For other options, type
audio-recorder --help

Features
Whilst the feature set hasn’t changed since we last covered the app way back in the far reaches of yester year, the way in which some of the features are implimented has. The nifty advanced timer – which can be used to auto-record audio at a set time, stop recording upon silence or adhere to a file size limit, etc – is still useful but certainly lacks the user-friendliness of old. Quite frankly the manually-editable configuration file approach used is just too much of a chore to bother with.Recording can automatically triggered by various Linux music players – including Ubuntu default Banshee – as well as with Skype.
The Indicator-Applet used houses four standard options: hide window, stop/start recording, pause recording and quit. The icon used, however, leaves a lot to be desired.
Install
Available for Ubuntu 10.10 and 11.04, Audio Recorder can be installed via its own dedicated PPA.To install via terminal issue the following commands: -
sudo apt-add-repository ppa:osmoma/audio-recorder
sudo apt-get update && sudo apt-get install audio-recorder
sudo apt-get install gir1.2-appindicator3-0.1
sudo apt-get install libappindicator3-dev
sudo apt-get install libappindicator3-1
Audio Recorder can be launched from the Applications > Audio/Sound sub menu. For 11.04 users just search ‘Audio Recorder’ in the Application lense.sudo apt-get update && sudo apt-get install audio-recorder
sudo apt-get install gir1.2-appindicator3-0.1
sudo apt-get install libappindicator3-dev
sudo apt-get install libappindicator3-1
Timer commands
Timer commands can stop, start and pause recording on a given condition.The general syntax of the commands are
start [at | if | after | on] condition
stop [at | if | after | on] condition
pause [at | if | after | on] condition
The timer field can contain several commands and lines written in English. Press the [Save] button or CNTR + S keys to save the command text. Use the # character to comment out unused lines.
Conditions
Clock time:
This can stop or start the recording at given clock time. The time has format hh:mm:ss (hours:minutes:seconds) and you can either use the 24-hour clock or 12-hour notation with am or pm suffix (ending).These two timer commands will start recording at 09:30 pm.
start at 09:30 pm
start at 21:30
These commands will stop recording at 9 o'clock in the morning.
stop at 09:00
stop at 09:00 am
The time is valid once a day. The command will fire again next day.
Note. Use the colon ":" to distinguish clock time (hh:mm::ss) from time period or duration.
Stop or pause recording on silence:
Use the silence word to stop or pause recording when there is no particular input on the line. You can also give the silence duration in minutes/seconds and signal level in decibel (dB) or percent (%). The default silence period is 7 seconds and the default level value is -24 dB (that is around 7%).Notice: If you use the silence word to pause recording, the recording will automatically continue after the condition becomes false (untrue).
Some examples
stop if silence
stop if silence 5s And
pause if silence 5s -24dB
pause if silence In these two cases the recording will pause when the average signal level goes under -24dB (7%) for 5 seconds time. The recording will automatically resume when the signal level rises over -24dB (ca. over 7%).
Activate recording on sound or voice:
Use the sound, voice or audio words to start recording when the signal level rises over a given level. All these three words mean the same. As with the silence command, you can give the duration in seconds and signal levels in dB or %. The default duration is 7 seconds and the default level value is -24 dB (that is around 7%).Examples
start if sound
start if sound 4s
start if voice 3 sec 10%
start if audio -20dB
Notice: If you use the sound (voice or audio) words to start recording, the recording will automatically pause temporarily when the signal level drops under the given level value.
Click the level-bar to show/hide the current % or decibel (dB) value.
File size:
Stop or pause recording after certain file size. The file size must be an integer or decimal number. The size unit can be bytes, kB, MB, GB or TB.For example this will stop recording when the file size reaches 500 KB.
stop if 500 kB
pause if 0.5MB
This will stop recording after 2GB or 12:00 pm.
stop after 2 GB | 12 pm
Time period:
Stop, start or pause recording after given time period. The period or duration has syntax #h #m #s.Eg. this command will stop recording after 1 hour 20 minutes and 15 seconds.
stop after 1h 20m 15s
This will start recording after 22 minutes.
start after 22min
And this will pause recording after 30 minutes or 20 MB.
pause after 30 minutes | 20 mb
You can abbreviate the word hour with h, minutes with m or min, and seconds with s or sec.
Combine several values in one command
You can add several conditions to one line. Separate the conditions with the | character. The values are then or'ed.For example, this will stop recording after 20 minutes or when the file size exceeds 1GB or if there is no input (the line is empty, silent) in 5 seconds time.
stop after 20 min | 1GB | silence 5s
Another example.
start if sound 6% | 10:00 pm
Commenting out lines
Use the # character to comment out (deactivate) lines.This command has no effect.
# stop after 800 MB | 20:00:00
Command-line options related to the timer
You can study the audio level values by starting the program with --debug-signal option. The program will then print various level values (signal values) in dB (decibel) and % format. Pay attension to the last "Avg.rms=" value. The timer will use it to trigger the commands.This example will start the program from a command line. Start a terminal window from the desktop's main menu and type
audio-recorder --debug-signal
or
audio-recorder -d
Then activate the timer and study the "Avg.rms" value. It may help you to set correct level value for the silence and sound|voice|audio commands.
Notice: You must activate the timer, and use one of silence, sound, voice or audio commands to see the level values.
Controlling the recorder from command line
You can easily control the program from a terminal window by using the -c or --command argument.Valid commands are: status, start, stop, pause, show, hide and quit.
Some examples:
audio-recorder --command start
audio-recorder --command start,hide
audio-recorder --command hide
audio-recorder --command stop
audio-recorder --command stop,hide
audio-recorder --command quit
The status command returns one of these strings: 'not running', 'on', 'off' or 'paused'.
audio-recorder --command status
For other options, type
audio-recorder --help

 Published on Gizmo's Freeware (http://www.techsupportalert.com)
 Linux Mint [2] is one of the top free operating systems widely used in the world and currently receives the highest hits at DistroWatch [3].Even though it's an Ubuntu-based system, Linux Mint features only one panel at the bottom which looks closer to the taskbar in the Windows system, and a well-organized start menu complete with a useful Search box.  It also pre-installs some proprietary software, including the Adobe Flash plugin and necessary media codecs, by default so that you can view streaming media, such as YouTube videos in a browser, and play mp3, mp4 or most other media files with a player right away out of the box.The MATE Edition of Linux Mint 13 Maya uses MATE [4], a traditional desktop environment which continues to develop as a fork of GNOME 2. If you have this Edition installed in your PC, you might find these tips and tricks useful for working with the system. Note: The steps described in this article work best with Linux Mint 13 Maya [MATE Edition]. If you're using the Cinnamon Edition, please check out this article [5].
Frequently used programs can be easily pinned to the panel.
When you set the panel to be transparent in the default Mint-X theme, you will find that some panel items' backgrounds are not transparent, but you can opt for one of the other themes which come with the transparent background for the panel items. If you prefer the default theme with the items' backgrounds transparent, some tweaks are needed with the steps below:
Like the Windows' Start button, Linux Mint has an advanced Gnome menu called "mintMenu" where you can start doing things like running a program, looking for files, log out or quit the system and so on. This menu allows you to set your personal preferences with the steps below, for example:
The font type and color of the panel clock follow the windows text in a theme by default. In particular, if the font color is black and shown on a dark background through a transparent panel, you can't read the clock clearly, but you can tweak it by changing the font color. And you can define the font type for your panel clock as well. The code in Step 1 below sets the font color to white and applies Digital Face font (Note 1), bold and size 16.
Note 2: The filename leading by a dot represents it's a hidden file and visible by toggling the key Ctrl-H in the file browser.  [7]When you double-click the title bar of a window, the default setting is to maximize a window. Since there's already a maximize button you can use for this, I always like to change the default setting to rolling up a window when I double-click on its title bar.
Linux Mint is using the Mint-X as the default theme, but you can either select another theme or customize it to suit your preferences easily.
In addition to the Computer and Home icons, Linux Mint adds an icon to the desktop for every removable drive that you attach to your system. The icons can be hidden by these steps:
Windows Explorer allows for users to set a default view to all folders. In almost the same way, Linux Mint's Caja File Browser allows for these settings:
When running a Caja file browser, you will see that the folder icons are predetermined by the theme you set. If you wish to change a folder icon to another for it to stand out from the system-wide icons, follow these steps:
In the Mint file system, you can use Caja file browser to browse most files but can only write files in your home folder /home/your_name and its sub-folders such as Desktop and Documents. If you have to rename a folder or write files outside of your home folder using the file browser, you won't be able to but you can create an advanced file browser for this purpose.
Keyboard shortcuts are preset in the system, but you can add new ones or change them easily. For instance, the keyboard shortcut to the Terminal is disabled by default and you can change it to Ctrl+Alt+T which is common in Linux system.
Note 2: Shortcuts begin with XF86 refer to special keys available to some multimedia keyboards. Note 3: Keyboard shortcuts can also be set by changing keybinding values with Configuration Editor. Press Alt+F2 and enter metaconf-editor, then navigate to apps > meta_settings_daemon > keybindings, or apps > marco > global_keybindings and window_keybindings. Xkill is part of the X11 utilities pre-installed in Linux Mint and a tool for terminating misbehaving X clients or unresponsive programs. You can easily add a shortcut key to launch xkill with the steps below.
Note: As an alternative, you can right-click the panel, select "Add to panel", then choose "Force Quit" to add to the panel. This works similarly to the above but it's activated from a button on the panel instead of the keyboard shortcut. If you press Ctrl+Alt+Delete, Linux Mint brings you a menu to shut down, restart, or suspend your system. But for some reason you might encounter that the system freezes, the mouse cursor can't move, neither pressing Ctrl+Alt+Delete can work. Remember that there's a shortcut key Alt+PrintScreen+K that can bring you back to the log-in screen immediately without the need to reboot the system. That's a time saver. As an alternative, you can also use Ctrl+Alt+Backspace to do the same. If this shortcut key is disabled, you can easily enable it by the following steps:
If you use a PC with an integrated audio device and it has no sound when playing a media file on a player, try these simple steps to set Sound Preferences for your PC. It works for me for the audio device I have.
Each time when you login to Linux Mint, it plays a login sound. If you don't like to listen to it each time you login, you can easily disable it, or change it to your favorite sound.
Do you prefer Windows TrueType fonts to the default fonts installed by Linux Mint? The mscorefonts package containing most Microsoft fonts can be installed and configured easily in a few steps below:
Note: If you like the Tahoma font which is not included in the mscorefonts package, you might want to copy the two files tahoma.ttf and tahomabd.ttf from /Windows/Fonts and install them. Screenlets are small applications to represent things such as sticky notes, clocks, calendars around on your desktop. You can launch a pre-installed screenlet from Screenlet Manager, or install a new one into the Manager for launching it. Here are the steps for installing and launching a screenlet, for example, WaterMark System Information.
Linux Mint uses OpenJDK by default, but some web services might need the Oracle Java Runtime Environment (JRE) to be installed for running the services properly. If you would like to get the proprietary Oracle Java package for your system, you can download and install it with the steps below:
The Ubuntu Apps Directory [15] is one of the good sources to look for applications to run in Linux Mint system. On a web page listing a product such as K3b [16], you can click a download button, in which the APT protocol is applied to invoke the default package manager to download and install software for you, right from a web browser and pretty straightforward. This works well when you're using Firefox which allows you to choose "AptUrl" to handle the protocol. But when you're using Chrome, clicking the download button triggers "xdg-open" which is unable to detect the MATE desktop environment. With some tweaks below, you can then use Chrome to download software from the Ubuntu Apps Directory.
Linux Mint's Software Manager lets you search and get free software, or straight from the Menu, you can type an application name into the Search box to see if the software has been installed and ready for use. If the software has not been installed, you can click "Install" when a software package is shown in the search result. What's more, you can also go to Menu > Package Manager, type in an application name to search and install a software package from the repositories. Besides this, you can browse the Ubuntu Apps Directory to find software products you need as mentioned in the tip above. Alternatively, you can get the latest freeware applications by clicking the Install this now button from the GetDeb Repository [17] after the getdeb package is installed with the instructions given. See also our Best Free Software for Linux [18]. Linux Mint is capable of reading and writing files stored on Windows formatted partitions, but partitions must be 'mounted' before they can be accessed each time you start up the system. With these steps, you can auto mount the drives or partitions without the need to manually mount them for access.
Note: If you need to identify disk partitions by label, paste ls /dev/disk/by-label -g in Terminal, or to view partition sizes and file systems, enter sudo fdisk -l. Disk Utility mentioned in "Name or Label a Partition" also gives you a glance of device numbers, partition types, sizes and labels. A USB storage device plugged into the system usually mounts automatically, but if for some reasons it doesn't automount, it's possible to manually mount it with these steps.
The File Browser shows the root directory as File System for your Mint system partition. If you have other partitions (or volumes), it shows them as xx GB Filesystem if they’re not named or labelled. Using Disk Utility is one of the effective ways to name a partition easily:
Note 1: If the option for "Edit Filesystem Label" is not shown, click "Unmount Volume" before hand. In case you can't unmount a volume, try Storage Device Manager to unmount it. See Auto Mount Drives at System Startup. Note 2: This tip is for naming a partition using Disk Utility, use other advanced features such as format, edit or delete partition with caution as they can delete data on your disk. In Windows, you can place a program shortcut in a startup folder for running a program automatically when the system starts. In Linux Mint, you can do the same in this way:
Linux Mint offers you a Mint Display Manager (MDM) to configure a login session. You can use it to change a login screen or a theme you like in a few steps:
Under the same tab, you can choose a style "Themed with face browser", which lists user names on a login screen and saves you the trouble of typing out a username each time you log in:
Some themes are made for Gnome Display Manager (GDM), but you can also add it to MDM with just a minor tweak:
After full installation, Linux Mint is set to be the default operating system to boot up if no key is pressed within a few seconds on a multi-boot system. You might want to set your preferred operating system to boot up by default. This can be done easily with StartUp-Manager.
Note: If your startup splash logo is changed to text after applying a graphics driver, the StartUp-Manager can be used to change the text back to the logo by adjusting to higher resolution and color depth supported by the driver. Each time when Linux Mint updates to a new Linux kernel, the old one is left behind and the boot menu gets longer. If your new Linux kernel works well, it's safe to remove the old one and clean up the boot menu. Do take these steps carefully as incorrect removal of the items can make your system unbootable.
A simple command can be entered in the Terminal to schedule a time for the system to shut down.
Alternatively, you might want to download and install GShutdown, which is a GUI program for scheduling a time to shutdown the system.
