Setting up automated emails in Joomla
You can setup Joomla to send automated emails from your personal email account. To do so, go to Global Configuration-->Server. Under Mail Settings, set the mailer to SMTP (not PHP) and specify your email address. Leave the Sendmail Path settings unchanged. Under SMTP authentication, check Yes. To enter the SMTP host settings, you'll need to check your email provider's help files. In most cases, it is smtp.yourmailprovider.com
Creating a sitemap in Joomla
Sitemaps are great for search engine optimization and if you haven't created one for your site yet, you should consider doing so. In order to create or generate sitemaps, most CMSes (including Joomla) come with extensions or plugins. However, installing too many extensions or plugins can often slow down your website. Thankfully, in Joomla you can manually create a sitemap and thus avoid activating one extra extension.
To create a sitemap, create a new article and name it Sitemap. In its body, type: loadposition sitemap
Now, create a new menu item named 'Sitemap' and make it point to the article.
Next, setup a new module. In the 'Position', simply type Sitemap and check the 'always show sub-menu items' as well as 'expand menu' options. You can add modules to each menu. Also, if you so desire, you can further improvise your sitemap by using CSS and JavaScript (not mandatory, though).

Creating a 'To-Do' reminder script
Sometimes, it gets tough to maintain a To-Do list properly when working on the computer. Unless we install dedicated software for task management, we are likely to forget an important deadline. If you've suffered in past too, now create a script that notifies you of your pending tasks.
First, create a script (say, notify.sh), using the following command:
#/bin/bash
if < $# -ne 2 >
then
xmessage -default EXIT -center “usage: notify “
else
while true
do sleep “$1”
xmessage -default EXIT -center “$2”
done
fi
You can then run the above script as follows:
~$ nohup ./notify 100 “Pending task” &
The 'nohup' and '&' in the above command ensures that the script runs in the background, so that you can close the terminal. When you wish to stop the reminder, simply KILL the running process.
Combining/extracting audio files
You can manipulate audio files from the terminal itself using the 'sox' command. In order to combine two audio files into a third file, use the following command:
$ sox -m file01.wav file02.wav outfile_file.wav
Here, we are combining 'file01.wav' and 'file02.wav' into a separate 'output_file.wav'
Similarly, to extract a segment of an audio file, we can use the 'trim' option as follows:
sox file01.wav file02.wav trim
In the above syntax,
To do so, use the command:
sox abc.wav xyz.wav trim 0 25

Using Gmail without Internet
If you are travelling or experiencing sporadic Internet connectivity issues, your work may come to a stand still. However, you can still keep in sync with your emails. To do so, download the Gmail Offline Extension For Google Chrome from https://chrome. google.com/webstore/detail/ejidjjhkpiempkbhmpbfngldlkglhimk
Once installed, run it. You will be greeted with a choice to enable/disable Offline Mode. Enable it.
Once done, all your mail will be synced with your web browser itself, so you can access it even without an Internet connection. Simply select “Offline Gmail” from Apps menu. You can archive, delete, edit, modify and arrange your mails without connectivity. The extension will automatically sync your data with the online Inbox.
Quite obviously, you should not use this feature on public computers.
