7 Great Linux Statistical Analysis Tools

Filed under
GNU
Linux
Software
Sci/Tech

Science is the effort of seeking to comprehend how the physical world works. From observation and experimentation, science uses physical evidence of natural phenomena to compile data and analyze the collated information.

In modern research it is essential for scientists to keep abreast of the latest statistical software. Just like the fast moving world of research, developments in statistical software and methods continue to abound. Making full use of the improvements in computer software helps to advance the pace of research.

Science really prospers and advances when individuals share the results of their experiments with others in the scientific community. There is a certain logic that scientific software should therefore be released in a freely distributable environment.

Linux is particularly strong in the field of open source statistical software. The purpose of this article is to identify software for performing statistical analysis. This type of software helps to summarize data in a shorter form, and helps scientists understand a concept or representation and make possible predictions based on this understanding.

Cantor 19.08

Filed under
KDE
Sci/Tech

Since the last year the development in Cantor is keeping quite a good momentum. After many new features and stabilization work done in the 18.12 release, see this blog post for an overview, we continued to work on improving the application in 19.04. Today the release of KDE Applications 19.08, and with this of Cantor 19.08, was announced. Also in this release we concentrated mostly on improving the usability of Cantor and stabilizing the application. See the ChangeLog file for the full list of changes.

For new features targeting at the usability we want to mention the improved handling of the “backends”. As you know, Cantor serves as the front end to different open-source computer algebra systems and programming languages and requires these backends for the actual computation. The communication with the backends is handled via different plugins that are installed and loaded on demand. In the past, in case a plugin for a specific backend failed to initialize (e.g. because of the backend executable not found, etc.), we didn’t show it in the “Choose a Backend” dialog and the user was completely lost. Now we still don’t allow to create a worksheet for this backend, but we show the entry in the dialog together with a message about why the plugin is disabled.

Sci/Tech

Dear all,

I am pleased to announce the 10th release of GNU Astronomy Utilities
(Gnuastro 0.10).

Gnuastro is an official GNU package of various command-line programs
and library functions for the manipulation and analysis of
(astronomical) data. All the programs share the same basic
command-line user interface (modeled on GNU Coreutils). For the full
list of Gnuastro's library, programs, and a comprehensive general
tutorial (recommended place to start using Gnuastro), please see the
links below respectively:

https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-library.html
https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-programs-list.html
https://www.gnu.org/s/gnuastro/manual/html_node/General-program-usage-tutorial.html

Many new features have been added, and many bugs have been fixed in
this release. For the full list, please see [1] below (part of the
NEWS file within the tarball). Some of the highlights are: 1) You can
now do column arithmetic (on FITS and plain text tables) directly
within the Table program, it also has some operators unique to table
columns for example conversion of pixel to world coordinate system
(WCS) coordinates and vice-versa. 2) Crop can now be used to pull out
sections of 3D data cubes also. 3) You can let CosmicCalculator find
the red-shift by identifying an emission line's wavelength or name,
and its observed wavelength.

Here is the compressed source and the GPG detached signature for this
release. To uncompress Lzip tarballs, see [2]. To check the validity

Hello everyone! The second part of this year's GSoC is almost over, so I was due to let you know the progress made in the last 3 weeks. I can assure you we haven't lazed since then. I think I managed to make quite good progress, so everything is going as planned, or I could say that even better. If you haven't read about this year's project or you just want to go through what has already been accomplished you can check out my previous post.

So let's just go through the new things step by step. I'll try to explain the respective feature, and also give examples using videos or screenshots.

The first step was to improve the welcome screen and make it easily usable, dynamic, clean and intuitive for users. This step was very important since the welcome screen is what the users will first get in contact with when they start using LabPlot.

11 Best Free Linux Desktop Genome Browsers

Filed under
GNU
Linux
Software
Sci/Tech

In the fields of molecular biology and genetics, a genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than 3 billion DNA base pairs—is contained in all cells that have a nucleus.

In bioinformatics, a genome browser is a graphical interface for display of information from a biological database for genomic data. They are important tools for studying genomes given the vast amounts of data available. They typically load very large files, such as whole genome FASTA files and display them in a way that users can make sense of the information there. They can be used to visualize a variety of different data types.

Genome browsers enable researchers to visualize and browse entire genomes with annotated data including gene prediction and structure, proteins, expression, regulation, variation, comparative analysis, etc. They use a visual, high-level overview of complex data in a form that can be grasped at a glance and provide the means to explore the data in increasing resolution from megabase scales down to the level of individual elements of the DNA sequence.

16 Best Free Linux Chemistry Tools

Filed under
Software
Sci/Tech

Chemistry is the study of matter and the changes it undergoes. It is an extremely vivacious science which deals with a molecular scale and atomic interpretation of the world we live in, helping us to understand that world. Chemistry is regarded as the central science, given its close links with physics and engineering, with biology and medicine, and with geology and earth science.

There are a number of different branches of chemistry. These include organic chemistry which studies the structure, properties, reactions, and composition of carbon-based compounds, and inorganic chemistry which deals with non-carbon compounds. Another important subdiscipline is physical chemistry which deals with the relations between the physical properties of substances and their chemical formations studying, in particular, atomic, subatomic, macroscopic, and particulate phenomena in chemical systems.

Chemistry is found in many different areas including all spheres of industry, research, teaching, forensic science, public health and much more. Moreover, at a fundamental level we are all chemists. Each time we breathe, boil a kettle, or strike a match, a chemical reaction takes place. We develop and function as a consequence of chemical processes taking place in our body. Chemistry therefore plays a significant role in everyone’s lives.

Science really prospers and advances when individuals share the results of their experiments with others in the scientific community. There is a certain logic that scientific software should therefore be released under an open source license. This article focuses on selecting the best open source software for chemistry. Hopefully there will be something for interest here for all budding chemists.

Sci/Tech

Solving computational problems was the first inspiration behind the invention of computers. Although modern computers have come a long way since its inception, it continues to play the de-facto role in solving complex computations. A Computer Algebra System (CAS) is a software environment that allows tackling modern-day, complex computational problems without having to manipulate complicated equations or computational systems manually. These computer algebra systems can manipulate mathematical formulae in a manner similar to traditional mathematicians and thwarts away potential errors effectively. There are a wide variety of computer algebra systems for Linux, both general-purpose and specialized.

Games: CodeWeavers, gamepad and Cascade

  • Linux 5.4 To Fix Many Newer 64-bit Windows Games On Wine / Steam Play

    A kernel patch from CodeWeavers is landing in the Linux 5.4 kernel and will help some 64-bit Windows games run nicely under Wine (and the likes of CrossOver / Valve's Proton) with newer Intel and AMD systems. With the few x86 Assembly patches for Linux 5.4 is a UMIP addition by CodeWeavers' Brendan Shanks that ends up being quite important for running a number of Windows games under Proton/Wine on newer AMD/Intel Linux systems.

  • You may want to hold off on Linux Kernel 5.3 and systemd 243 if you use a gamepad

    Did you do a big system upgrade recently and notice you're having gamepad issues? You're not alone. Time to downgrade perhaps. To be clear this might only be an issue for the more bleeding-edge distributions which update more often, or those of you who are doing some manual updates to their system. The distributions that update more slowly like Ubuntu are likely unaffected right now.

    HPE, one of SUSE’s most important partners in High-Performance Computing and the advancement of science and technology, is now building NASA’s new supercomputer named “Aitken” to support Artemis and future human missions to the moon. HPE’s “Aitken” supercomputer will be built at NASA’s Ames Research Center and will run SUSE Linux Enterprise HPC (co-located where the Pleiades supercomputer – also SUSE-based – has been advancing research for several years). Aitken will run extremely complex simulations for entry, descent and landing on the moon as part of the Artemis program. The missions include landing the next humans on the lunar south polar region by 2024 (on the rim of the Shackleton crater, which experiences constant indirect sunlight for a toasty -300 degrees Fahrenheit).
