  • Director Digital Business Solutions to kick off ApacheCon Europe in Berlin

    The European Commission, a long-time user of open source software, is strengthening its relationship with the Apache Foundation. At the Hackathon in May, the Commission brought together more than 30 developers involved in six different Apache projects. Attendees came from Croatia, Ireland, Poland and Romania, and even from Russia and the United States. At the meeting, many developers met in person for the first time. The hackathon helped the project members build connections and strengthen bonds.

  • FOSSCOMM 2019 aftermath

    FOSSCOMM (Free and Open Source Software Communities Meeting) is a Greek conference aiming at free-software and open-source enthusiasts, developers, and communities. This year was held at Lamia from October 11 to October 13. It is a tradition for me to attend to this conference. Usually I have presentations and of course booths to inform the attendees about the projects I represent. This year the structure of the conference was kind of different. Usually the conference starts on Friday with "beer event". Now it started with registration and a presentation. Personally I made my plan to leave from Thessaloniki by bus. It took me about 4 hours on the road. So when I arrived, I went to my hotel and then waited for Pantelis to go to the University and setup our booths.

  • Empowering Generations of Digital Natives

    Technology is changing faster each year. Digital literacy can vary between ages but there are lots of ways different generations can work together and empower each as digital citizens. No matter whether you’re a parent or caregiver, teacher or mentor, it’s hard to know the best way to teach younger generations the skills needed to be an excellent digital citizen. If you’re not confident about your own tech skills, you may wonder how you can help younger generations become savvy digital citizens. But using technology responsibly is about more than just technical skills. By collaborating across generations, you can also strengthen all your family members’ skills, and offer a shared understanding of what the internet can provide and how to use it to help your neighborhoods and wider society.

  • How to Verify Smart Contracts on Etherscan

    You have your smart contract written, tested, and deployed. However, customers aren’t willing to do business with you unless they know the contract’s source code. After all, it could be set up in a way that’s not in their interest. Thankfully, Etherscan offers a neat tool that allows you to verify smart contracts so interested parties can see the source code and verify for themselves that everything is as it should be. While the process is simple, there are intricacies that might cause problems, especially to people not very familiar with Ethereum and the Solidity programming language.

  • Ethical Open Source: Is the world ready?

    Given its incredible popularity in the marketplace, there is no question that many software developers (and their respective companies) today see great value in using software that is subject to open source licenses. Users focus on the advantages to be had by gaining access, usually at no or minimal charge, to the software’s source code and to the thriving open source community supporting such projects. Powered by a worldwide community supporting the code base, open source code is generally perceived to be more reliable, robust and flexible than so-called proprietary software, with increased transparency leading to better code stability, faster bug fixes, and more frequent updates and enhancements. Historically the question of ethics and open source software (OSS) has mainly focussed on the goal of obtaining and guaranteeing certain “software freedoms,” namely the freedom to use, study, share and modify the software (as exemplified by the Free Software Definition and copyleft licenses such as the GPL family), and to ensure that derivative works were distributed under the same license terms to end “predatory vendor lock-in.”

Programming: SystemView, JDK, VimL and Bazel

  • New SystemView Verification Tool from SEGGER is Compatible with Windows, Linux, and macOS
  • 5 steps for an easy JDK 13 install on Ubuntu
  • Basic Data Types in Python 3: Strings
  • Excellent Free Books to Learn VimL

    VimL is a powerful scripting language of the Vim editor. You can use this dynamic, imperative language to design new tools, automate tasks, and redefine existing features of Vim. At an entry level, writing VimL consists of editing the vimrc file. Users can mould Vim to their personal preferences. But the language offers so much more; writing complete plugins that transform the editor. Learning VimL also helps improve your efficiency in every day editing. VimL supports many common language features: variables, control structures, built-in functions, user-defined functions, expressions first-class strings, high-level data structures (lists and dictionaries), terminal and file I/O, regex pattern matching, exceptions, as well as an integrated debugger. Vim’s runtime features are written in VimL.

  • Google Releases Bazel 1.0 Build System With Faster Build Performance

    Bazel is Google's preferred build system used by many of their own software projects. Bazel is focused on providing automated testing and release processes while supporting "language and platform diversity" and other features catered towards their workflow. Bazel 1.0 comes at a time when many open-source projects have recently been switching to Meson+Ninja as the popular build system these days for its fast build times and great multi-platform build support. Bazel also still has to compete with the likes of CMake and many others.

  • Bazel Reaches 1.0 Milestone!

    Bazel was born of Google's own needs for highly scalable builds. When we open sourced Bazel back in 2015, we hoped that Bazel could fulfill similar needs in the software development industry. A growing list of Bazel users attests to the widespread demand for scalable, reproducible, and multi-lingual builds. Bazel helps Google be more open too: several large Google open source projects, such as Angular and TensorFlow, use Bazel. Users have reported 3x test time reductions and 10x faster build speeds after switching to Bazel.
