If I open a file using gedit, after closing the file, in addition to the file, an additional file is added with ~ at the end of the file name. Why does this happens?
Sometimes, I get following error or unable to lock directory /var/lib/apt/lists/ while updating the system. What does that mean?
The output in the terminal is as follow:
$ sudo apt update
Reading package lists... Done
E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/
$ sudo apt-get update

The IQmol is widely used to analyze the ouptut files form Q-Chem electronic structure theory code. In Windows, it is straight forward to install IQmol.exe package and it works fine.
However, in Linux distribution (Ubuntu 16.04), the .deb package can be installed just by downloading and opening in package installer. However, some functionalities are missing in installation.
Installation from the source.
I cloned the source code from GitHub.com/Iqmol and tried ./configure. I got following error.
./configure

Could not find a package configuration file provided by "Qt5QtCore" with
any of the following names:

Add the installation prefix of "Qt5QtCore" to CMAKE_PREFIX_PATH or set
"Qt5QtCore_DIR" to a directory containing one of the above files. If
"Qt5QtCore" provides a separate development package or SDK, be sure it has
been installed.

Then, you can use "convert" to convert form .png to .eps as follow.
convert combinedFigure.png combinedFigure.eps
This is how I got the work done. The final output file in .eps is not as clear as I expected. But for now, it is suffice. If I come to know more about this, I will update this post.
The Physics Nobel Prize in 2019 has just been announced.
The 2019 Physics Noble prize one-half goes to James Peebles (Canadian American Physicist) for the "theoretical discoveries in physical cosmology", other half jointly to Michel Mayor and Didier Quer Queloz for the discovery of an exoplanet orbiting a solar-type star"
The official site says:
The 2019 Nobel Prize in Physics are awarded ”for contributions to our understanding of the evolution of the universe and Earth’s place in the cosmos”, with one half to James Peebles “for theoretical discoveries in physical cosmology” and the other half jointly to Michel Mayor and Didier Queloz “for the discovery of an exoplanet orbiting a solar-type star.”
Nobel prize in Physics is awarded each year for the fundamental contribution in Physics.
Here are three Professor's short biography (from wiki)
"Prof. Peebles OM FRS (born April 25, 1935) is a Canadian-American physicist and theoretical cosmologist who is currently the Albert Einstein Professor Emeritus of Science at Princeton University.[1][2] He is widely regarded as one of the world's leading theoretical cosmologists in the period since 1970, with major theoretical contributions to primordial nucleosynthesis, dark matter, the cosmic microwave background, and structure formation. His three textbooks (Physical Cosmology, 1971; Large Scale Structure of the Universe, 1980; Principles of Physical Cosmology, 1993) have been standard references in the field."
"Prof. Michel G.E. Mayor (born 12 January 1942, Lausanne) is a Swiss astrophysicist and professor emeritus at the University of Geneva's Department of Astronomy.[1] He formally retired in 2007, but remains active as a researcher at the Observatory of Geneva. He is co-winner of the 2010 Viktor Ambartsumian International Prize,[2] and the winner of the 2015 Kyoto Prize. Together with Didier Queloz in 1995 he discovered 51 Pegasi b, the first extrasolar planet orbiting a sun-like star, 51 Pegasi.[3] Mayor holds MS in Physics from the University of Lausanne (1966) and PhD in Astronomy from the Geneva Observatory (1971). His thesis also had an article called "Essay on the kinematical properties of stars in the solar vicinity: possible relation with the galactic spiral structure." He was a researcher at the Institute of Astronomy at the University of Cambridge in 1971. Subsequently, he spent sabbatical semesters at the European Southern Observatory (ESO) in northern Chile and at the Institute for Astronomy of the University of Hawaii system."
"Didier Queloz (born February 23, 1966) is a Swiss astronomer with a prolific record in finding extrasolar planets in the Astrophysics Group of the Cavendish Laboratory, Cambridge, and also at the University of Geneva. In 1995 Queloz was a Ph.D. student at the University of Geneva when he and Michel Mayor, his doctoral advisor, discovered the first exoplanet around a main sequence star.[1] Queloz performed an analysis on 51 Pegasi using radial velocity measurements (Doppler spectroscopy), and was astonished to find a planet with an orbital period of 4.2 days. He had been performing the analysis as an exercise to hone his skills.[2] The planet, 51 Pegasi b, challenged the then accepted views of planetary formation, being a hot Jupiter or roaster. He has received the 2011 BBVA Foundation Frontiers of Knowledge Award of Basic Sciences (co-winner with Michel Mayor) for developing new astronomical instruments and experimental techniques that led to the first observation of planets outside the solar system. In 2017 he received the Wolf Prize in Physics.[3]. In 2019 he received the Nobel Prize."
