16 Best Free Linux Chemistry Tools

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.

EU approves IBM's $34 billion acquisition of Red Hat

Filed under
Red Hat

The European Commission has unconditionally approved IBM's $34 billion takeover of open-source software maker Red Hat.

In a statement, the European Commission said that following an investigation, it concluded that the proposed deal "would raise no competition concerns".

Since IBM doesn't stand among the top two companies in the cloud computing market, and isn't dominant in any sector in which Red Hat is also present, there was no reason for regulators to believe that the merger would raise competition concerns.

"During its investigation, the Commission assessed the impact of the proposed transaction on the markets for middleware and system infrastructure software, where the activities of IBM and Red Hat overlap," the Commission said in its statement.

Delphi RAD tool (remember that?) gets support for Linux desktop apps – again

Filed under
Software

Hands On Texas software house Embarcadero Technologies has said it will license FmxLinux for Delphi, allowing developers to compile desktop applications for 64-bit Linux.

FmxLinux is a toolchain for compiling Linux desktop applications using Embarcadero’s Linux compiler for Delphi, which is also part of the RAD Studio bundle. FmxLinux was developed by a third party, Eugene Kryukov. It has been licensed under “a long term distribution agreement,” says Embarcadero’s Marco Cantu in the announcement this week.

Embarcadero is a division of Idera Software.

RAD Studio is already a cross-platform development tool, with support for Windows, macOS, Android and iOS. RAD Studio 10.2, released in 2017, included an LLVM-based Linux compiler for server applications, but not desktop. The new agreement completes the picture by adding desktop GUI (Graphical User Interface) applications.

Filed under
Linux

Do you need a new laptop or desktop, but don't know what to buy? Don't worry; this is a pretty common dilemma. While you can, of course, look into a Mac or Windows 10 computer, you should consider Linux too. A computer running, say, Ubuntu, can be great for productivity, education, creation, and more. Best of all, many top-tier Linux programs, such as GIMP and LibreOffice are totally free. And yes, your favorite web browsers such as Mozilla Firefox and Google Chrome will run on Linux too.

If you are open to the idea of buying a computer running a Linux-based operating system, you should definitely check out System76. Not only are its laptops and desktops of high quality, but its customer service is unrivaled. If you ever need help, you can contact an actual human being that is based in the USA. The support representatives aren't just reading off a script either -- these people are truly knowledgeable.

  • Week 4, Titler Tool and MLT – GSoC ’19

    It’s already been a month now, and this week – it hasn’t been the most exciting one. Mostly meddling with MLT, going through pages of documentation, compiling MLT and getting used to the MLT codebase.

    With the last week, I concluded with the rendering library part and now this week, I began writing a new producer in MLT for QML which will be rendered using the renderering library. So I went through a lot of MLT documentation, and it being a relatively new field for me, here is what I’ve gathered so far:

    At its core, MLT employs the basic producer-consumer concept. A producer produces data (here, frame objects) and a consumer consumes frames – as simple as that.

  • Daimler ordered to recall thousands of Mercedes in Germany over emissions cheating — report

                       

                         

    Germany's auto industry regulator, KBA, has ordered carmaker Daimler to expand its recall program to retrofit vehicles illegally fitted with emissions-cheating software, Germany's Bild newspaper reported on Saturday.

  • Daimler to recall 60,000 Mercedes diesels in Germany over emissions

                       

                         

    Daimler must recall 60,000 Mercedes diesel cars in Germany after regulators found that they were fitted with software aimed at distorting emissions tests, the Transportation Ministry said on Saturday.
     

                         

    The model affected is the Mercedes-Benz GLK 220 produced between 2012 and 2015.

  • Daimler Must Recall 60,000 Mercedes Cars for Emissions Breach

                       

                         

    Daimler has already recalled 3 million vehicles that are producing excess emissions from their diesel engines. The German news outlet, Bild am Sonntag, first reported the recall on Saturday and noted that the German regulatory authorities were expanding their investigation.
     

                         

    Suspicions were raised when Mercedes-Benz GLK 220 CDI cars produced between 2012 and 2015, only met emission limits when certain functions within the car's software were activated. The emissions scandal has tarnished many major automakers.

    Ive has been an indispensable leader at Apple and the chief guide of the company's aesthetic vision. His role took on even greater importance after Apple cofounder Steve Jobs died of pancreatic cancer in 2011. Apple will not immediately appoint a new chief design officer. Instead, Alan Dye, who leads Apple’s user interface team, and Evans Hankey, head of industrial design, will report directly to Apple’s chief operating officer, Jeff Williams, according to the Financial Times.

    Apple’s chief design officer Jonathan Ive will depart the company later this year, bringing an end to a tenure spent crafting some of technology’s most influential products, including the iPhone. Ive, who has led Apple’s design team since 1996, is leaving “to form an independent design company which will count Apple among its primary clients.” The company is called LoveFrom, and Ive will be joined by famed designer Marc Newson on the new venture. Despite stepping down from his executive position, Ive and Apple both claim he will still work “on a range of projects with Apple.”

Pumpkins, markets, and one bad Apple

Imagine your local farmers market: every Saturday the whole town comes together to purchase fresh and homemade goods, enjoy the entertainment, and find that there is always something for everyone. Whatever you need, you can find it here, and anyone can sign up to have their own little stand. It is a wonderful place, or so it seems. Now, imagine starting out as a pumpkin farmer, and you want to sell your pumpkins at this market. The market owner asks 30% of every pumpkin that you sell. It's steep, but the market owner -- we'll call him Mr. Apple -- owns all the markets in your area, so you have little choice. Let's continue this analogy and imagine that, since it is a little hard for you to make ends meet, you decide to tell your customers that they can come visit you at your farm to purchase pumpkins. Mr. Apple overhears and shuts your stand down. You explain that your business cannot be profitable this way, but the grumpy market owner says that you can either comply or find another place. At the end of your rope, you look for information about starting your own farmers market, but it seems Mr. Apple owns every building in town. In the midst of Apple announcing its new products, attention is drawn away from its ongoing battle to maintain its subjugation over users globally. The Netherlands’ Authority for Consumers and Markets (ACM) last month informed the U.S. technology giant of its decision that the rules around the in-app payment system are anticompetitive, making it the first antitrust regulator to conclude that the company has abused market power in the App Store. And while Apple is appealing this verdict, the European Union is charging the company with another antitrust claim concerning the App Store. Read more

Development version: GIMP 2.99.8 Released

GIMP 2.99.8 is our new development version, once again coming with a huge set of improvements. Read more Some early coverage:

    A new development version of GIMP is available to download and it carries some interesting new features. While this isn’t a new stable release — GIMP 2.10.28 is the most recent stable release (and the version you’ll find in Ubuntu 21.10’s archives) — the release of GIMP 2.99.8 is yet another brick in the road to the long-fabled GIMP 3.0 release.

Mozilla: Six-Year Moziversary, Thomas Park/Codepip, and Weak Response to Critics of Firefox Spyware

  • Chris H-C: Six-Year Moziversary

    I’ve been working at Mozilla for six years today. Wow. Okay, so what’s happened… I’ve been promoted to Staff Software Engineer. Georg and I’d been working on that before he left, and then, well *gestures at everything*. This means it doesn’t really _feel_ that different to be a Staff instead of a Senior since I’ve been operating at the latter level for over a year now, but the it’s nice that the title caught up. Next stop: well, actually, I think Staff’s a good place for now. Firefox On Glean did indeed take my entire 2020 at work, and did complete on time and on budget. Glean is now available to be used in Firefox Desktop.

  • Mark Surman: Exploring better data stewardship at Mozilla [Ed: Mozilla fails to admit that spying on Firefox users is wrong; now it's misframing the criticism and responds to a straw man]

    Over the last few years, Mozilla has increasingly turned its attention to the question of ‘how we build more trustworthy AI?’ Data is at the core of this question. Who has our data? What are they using it for? Do they have my interests in mind, or only their own? Do I trust them? We decided earlier this year that ‘better data stewardship’ should be one of the three big areas of focus for our trustworthy AI work. One part of this focus is supporting the growing field of people working on data trusts, data cooperatives and other efforts to build trust and shift power dynamics around data. In partnership with Luminate and Siegel, we launched the Mozilla Data Futures Lab in March as a way to drive this part of the work.
