Avogadro is a molecule editor and visualizer, and one of the most advanced open source scientific software tools. It features many capabilities that can be useful in teaching as education can be much more effective when theory is combined with the actual depiction of realistic models. Here is a basic tutorial on how to use Avogadro in education.

In my last article, I introduced the Libreboot project: a free software distribution of coreboot, which is itself an open-source BIOS replacement. I also talked about some of the reasons you may want to run a free software BIOS and discussed some of the associated risks.

In 1992 I started working for the Tandem Computers subsidiary in Sao Paulo, Brazil. I was part of the team that started Tandem's operations in Brazil, and at the time I was the one and only techie in the group. Tandem was later acquired by Compaq, and now it's the NonStop division inside HP. At the time, Tandem manufactured and sold a high availability Unix System, the NonStop Integrity. It ran a customized version of AT&T's Unix System V Release 4.0, and used a Veritas file system, which is quite similar to what we have today with LVM (Logical Volume Manager). read more

Using the Fibonacci sequence computation as an example, this article analyzes the speed advantage of an inline assembly implementation in comparison to the performance of other programming techniques such as the recursive algorithm, the dynamic programming implementation, the iterative approach, and the optimized matrix power algorithm. The target audience is software engineers interested in further accelerating the execution of their applications by handcrafting the assembler codes for the most performance-critical sections.

Google launched developer access to its lightweight, Android based “Brillo” OS for IoT, which initially supports a trio of ARM, Intel, and MIPS hacker SBCs. Google today launched a Brillo developer portal where code, development tools, and documentation for the Android-based Brillo embedded OS for Internet of Things devices can obtained. For now, gaining access […]

A controversial draft law, which one senator called a "surveillance bill by another name," has passed the Senate. CISA, the Cybersecurity Information Sharing Act (S. 754), will allow private companies to share cyber-threat data with the federal government, including personal user data, in an effort to prevent cyberattacks...

In my last article, I continued looking at the Django Web framework, showing how you can create and modify models. As you saw, Django expects you to describe your models using Python code. The model description is then transformed into SQL and compared with any previous version of the model that might have existed.

What is globalization? In software, globalization means two ways to make software useful globally:  internationalization and localization. Because technical folks don't enjoy typing long words, these are often abbreviated.

Automotive software issues, such as the Jeep hack and Volkswagen cheating on emissions tests, have made headlines this year, which means the public is thinking about software in cars like never before. Some experts have argued that mandating that such software be open source is a solution to the problem. Although there are definite benefits to public scrutiny of the software, code visibility alone is no guarantee. As Sam Liles explained to me in a recent email, open source code didn’t prevent ShellShock.
