Why are Native Americans Called Indians?

The term Indians as applied to Native Americans, or the indigenous peoples of the Americas, is thought to have originated in a misconception on the part of the Europeans who arrived in Central America in 1492. Since Christopher Columbus began his journey to America with the intent of finding an alternate route to Southeast Asia, he is said to have assumed that the people he came into contact with upon reaching land were Indians. Despite the fact that people probably realized this mistake within hours, the name remained in use. Similarly, the islands in Central America came to be called the "West Indies", as opposed to the "East Indies" that Columbus originally had in mind as his destination. In the 1970s, the academic world began promoting the term Native Americans as a politically correct alternative to Indians. Some people feel that Native Americans is more accurate and less stigmatizing. However, Native Americans also has some issues, as anyone born in the Americas, indigenous or not, could be considered "Native American" if the term is taken literally. "Indigenous peoples of the Americas" is the most accurate term, but too cumbersome to be used regularly in everyday speech. Native Americans caught on to some degree, especially in the media, but the term Indians is still widely used.

What is a Sea level? Are we at Sea level at Sea?

Sea level is a measure of the average height of the ocean's surface (such as the halfway point between the mean high tide and the mean low tide); used as a standard in reckoning land elevation.


Gravity is stronger in different places on Earth's surface, so sea level may be higher or lower depending on the strength of gravity.   Source

How Does Wi-Fi Work on Airplanes?

I have always come up with question in my head which I didn't have time to google. From, now on I am planning to google all those queries and put it here. Ok back to the question:

How Does Wi-Fi Work on Airplanes?

Source:

Transmitters on the plane communicate with a ground station, either using radio waves similar to a cellphone or through a satellite link, depending on the provider.

Satellite Communications
In a satellite communications system, a satellite antenna on top of the plane communicates with a satellite in orbit above the earth. The satellite also communicates with a ground earth station, which has a direct connection to the Internet. When a passenger requests a Web page on her laptop from the plane's Wi-Fi access point, the plane's electronics transmit the request to the satellite, which then relays it to the ground station. The ground station then transmits the requested page to the satellite, which in turn relays the data to the plane. The wireless access point then sends the data to the passenger’s laptop. Although the signals travel large distances, speeds of up to 11Mbps are currently available.


Ground-Based Cellular Networks
In a ground-based system, an antenna located on the bottom of the plane transmits and receives signals to and from ground-based towers and works in a similar way to mobile phone networks. The plane's antenna transmits signals to the nearest tower, which in turn relays the signals to a ground station. The ground station retrieves the necessary data, which the cell tower broadcasts to the plane. As providers erect more towers, the area covered by the network expands. For faster expansion, existing cellphone towers can be fitted with the necessary equipment. Due to FCC regulations, the network is not available below 10,000 feet as the license is only for aeronautical use.

Restrictions
To avoid disturbing other passengers, the systems automatically drop any packets containing voice data, while passing other data through. Due to the need to be in contact with a tower, ground-based systems do not work on international flights or over large bodies of water, and the service may slow down if a number of people on board the flight use the connection.

How to delete a UNIX directory with a hyphen in the name

rm -rf -- -directoryName
The -- after rm tells it to stop looking for options.

Alternatively, you can put "./" in front of directory name
rm -rd ./-directoryName

Search MS word files in a directory for specific content in Linux

We cannot use 'grep' command on MS word (.doc) file because the text, in a .doc file, is broken and interspersed with field codes and formatting information. If you search for something short then you have better chance of finding a match but search results won't be much helpful.







I think your best option would be do the search by doing 'Ctrl + F' on a folder to search specific string.

Unfortunately, for this search to work, you will have to copy the files to your local machine because windows uses indexing for string searches and indexing is not available on mapped network drives.

Case Insensitive search using grep
> grep -i "search_string" FileName.txt

How to fix “Firefox is already running” error + Open Suse

I was getting this error:
Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.


To fix this error:
