GNU GPLv3 At The Center Of The Black Hole Image

Scientists have finally seen what could not have been seen – a black hole. As fascinating is the fact that we can now ‘see’ a black hole, the story behind this achievement is even more fascinating.

It’s a story of victory of science in the political era of science denials. It’s a victory of diversity in the era of homophobia and sexism. It’s a victory of free software in the era of…well, we live in the era of free software.

Open Source Helped Scientists See The Black Hole

  • Open Source Helped Scientists See The Black Hole

    Free and Open Source software was at the center of the first image of a black hole. The team used three different imaging software libraries to achieve the feat. Out of the three, two were fully open source libraries – Sparselab and ehtim.

Black Hole Image Has an Open Source Connection

  • Black Hole Image Has an Open Source Connection

    Two imaging libraries responsible for the image are fully open source.

    Last week the whole world was stunned by seeing what was unseen – a black hole. Scientists were able to create picture of a black hole named Messier 87 in the Virgo A galaxy. The black hole is more than 55 million light years away.

    The first image of a black hole is the outcome of the Event Horizon Telescope (EHT) project, which created a virtual telescope as big as earth by networking 8 ground-based telescopes. The telescopes generated more than five petabyte of data. Collecting data was the first part of the puzzle. The team of scientists used various algorithms to fill gaps in this data to be able to generate an image of the black hole.

Databases: NoSQL, EnterpriseDB and RavenDB

  • Top Open source NoSQL database programs
    NoSql, it stands for Not Only SQL, refers to the non-relational database. The next generation database mainly addresses several key points: non-relational, distributed, open source, and horizontally scalable. The non-relational database has developed very rapidly due to its own characteristics. The NoSQL database was created to solve the challenges brought by the multiple data types of large-scale data collection, especially the big data application problem. It also supports easy replication, simple APIs, final consistency (non-ACID), and large data. It is stored by us with the most key-values, and of course other document types, column stores, graph databases, XML databases, and so on. Here are some top available NoSQL database programs in Open source or free category.

FOSS in Education and Sharing

  • The Untapped Potential of Making and Makerspaces
    Makerspaces are physical locations with equipment that students can use to undertake do-it-yourself (DIY) projects. Arguably, they have been around for decades; we just haven’t used the name makerspace. At my institution, the University of Massachusetts, Amherst, we’ve had a student-run DIY craft shop on our campus for more than 20 years. The difference between older forms of makerspaces like that craft shop and emerging ones is that the latter focus more heavily on digital making, such as 3-D design and printing, digital fabrication (sometimes called “FabLabs”), or the programming of open-source electronic hardware like the Arduino microcontroller. What is also new are the maker practices or principles of: 1) licensing digital designs and how-to instructions under a Creative Commons or similar copyright license and 2) openly sharing those designs through internet-enabled, cloud-based maker websites. Licenses chosen usually permit the sharing of the work with author attribution and, in some cases, permit new users to adapt and remix the work for other purposes. For example, at Thingiverse.com, 3-D modelers openly share their digital designs in this manner.

  • Tech That Makes Us Better Humans: JavaScript, Shudder, Chat Apps, Concordia, Signia
    Technology is a medium; sometimes it’s a humanizing, enchanting one. “Something about the interior life of a computer remains infinitely interesting to me; it’s not romantic, but it is a romance,” writes Paul Ford in his WIRED essay “Why I (Still) Love Tech.” “You flip a bunch of microscopic switches really fast and culture pours out.” To accompany Ford’s essay, we reached out to a bunch of people to ask them about the technology they love—the tools that make them better at being human. Here’s what we heard back.
  • Open-source RNA Analysis Tool Takes Root in Plant Biology
    An open-source RNA analysis platform has been successfully used on plant cells for the first time - a breakthrough that could herald a new era of fundamental research and bolster efforts to engineer more efficient food and biofuel crop plants. The technology, called Drop-seq, is a method for measuring the RNA present in individual cells, allowing scientists to see what genes are being expressed and how this relates to the specific functions of different cell types. Developed at Harvard Medical School in 2015, the freely shared protocol had previously only been used in animal cells. "This is really important in understanding plant biology," said lead researcher Diane Dickel, a scientist at the Department of Energy's Lawrence Berkeley National Lab (Berkeley Lab). "Like humans and mice, plants have multiple cell and tissue types within them. But learning about plants on a cellular level is a little bit harder because, unlike animals, plants have cell walls, which make it hard to open the cells up for genetic study." For many of the genes in plants, we have little to no understanding of what they actually do, Dickel explained. "But by knowing exactly what cell type or developmental stage a specific gene is expressed in, we can start getting a toehold into its function. In our study, we showed that Drop-seq can help us do this."

Events: OpenStack, Open Source Day (OSD), and Intel

  • OpenStack Keeps One Eye on the Prize, One Over Its Shoulder
    The OpenStack Foundation (OSF) used its recent Open Infrastructure Show (OIS) to remind the open source community of its importance, maturity, and flexibility. But the event also showed that the group understands that the virtualized infrastructure environment is evolving rapidly. I must admit that heading into the OIS event I was not expecting much. Conversations I have had over the past year continued to show a strong core of OpenStack supporters, but it seemed that the platform’s innovative spirit was diminishing. And in such a rapidly evolving technology segment, any sort of diminishing momentum is the equivalent of going backwards.
  • Open Source Day 2019 focuses on the cloud, security and development
    The 12th edition of Open Source Day (OSD) will take place today at the Legia Warsaw Stadium in Poland’s capital city. The event will include presentations, forums and nine technical sessions spanning automation, containerization, cloud computing, virtualization, security, monitoring, CI/CD, software and app development and databases.

  • Intel Pushes Open Source Hypervisor With Cloud Giants
    Intel, along with cloud giants Amazon and Google, is working on an open source hypervisor based on the rust-vmm project. The chipmaker discussed this and several other open source efforts at its Open Source Technology Summit, which kicked off yesterday. The company “is and has been one of the largest contributors to open source,” said Imad Sousou, Intel corporate vice president and general manager of system software products. “Intel is the No. 1 contributor to the Linux kernel. We write 10% to 12% of the Linux kernel code.” For the record: Red Hat is No. 2, and it contributes about 6%, according to Sousou.
