  • New open-source software predicts impacts of extreme events on grids

    A new, free, open-source software reliably predicts how damage from hurricanes, ice storms, earthquakes, and other extreme events will restrict power delivery from utility grids. The Severe Contingency Solver for Electric Power Transmission is the only software available—commercially or open-source—that reliably supports analysis of extreme events that cause widespread damage.

    [...]

    This is the first software to reliably, consistently, and accurately analyze extreme-event damage to a power grid—and it is the only software guaranteed to provide a solution for a severely damaged power grid. It runs on a variety of operating systems, including Windows, OS X, and Linux. That way, no matter who the user is, the software can be deployed effortlessly.
     
    The Severe Contingency Solver, which is currently being used by U.S. government agencies, has potentially broader applications. The Los Alamos team is now working on similar solver capabilities in power distribution and gas networks. These new tools will further help network operators and policymakers understand and quantify how multiple critical infrastructures will respond to extreme events where many components are out of service simultaneously. This provides situational awareness beyond commercially available analysis software and helps stakeholders better respond to extreme events, such as deciding to mobilize FEMA or dispatching additional repair crews from neighboring areas.

  • Why the Apache Unomi Open-Source Customer Data Platform Is Worth a Look

    Customer experience (CX) demands personalization, and personalization requires access to a wide variety of customer data. Today, that data is commonly maintained in separate, siloed systems of record and engagement. However, marketers need a consolidated 360-degree-view of customer data to personalize content and make relevant recommendations. Thus was born the customer data platform (CDP), a relatively new approach to master data management for CX data.

  • The open source business model: can 'free' be 'profitable'?

    The spirit and power of open source lies in freedom, and not in its being free.

  • The Open Science Of Reproductive Biology: A New Open-Source Project For Sperm Analysis

    Recently, a manifesto for reproducible science [1] has been published, where authors point to a list of good practices in order to guarantee the reproducibility of the scientific studies as much as possible. As part of what it is known as Open Science, one of the key points of this manifesto is the encouragement to make all data and software used publicly available, in order to make peer-review testing of the results and conclusions obtained in the corresponding studies. The problem here is that in most studies, the source code of the software used to either measure or analyze the data is private and inaccessible, making the comparison and understanding of why similar studies led to different conclusions difficult. Furthermore, an additional problem found is that, usually, the needs of the scientific community and the availability of commercial solutions for these needs are not always synchronized, with the former normally leading the latter. In other cases, the scientists need a level of flexibility to make changes that private solutions cannot offer because of the opaque nature of such programs.

    [...]

    In the recent years, some open-source alternatives have been proposed, but these programs are still way behind the commercial CASA systems in terms of ease of use and standardization, and they have not usually been designed to encourage the scalability and the continuity of the software development. Hence, the source code is usually written in one single file and published by references to static web pages or by links to a file hosting service, like Dropbox. In this scenario, users can download the software, but they cannot update or improve these programs for the benefit of other users. In the worst cases, the link is broken shortly after publication.

  • My Code Is Your Code: Embracing The Power Of Open Sourcing
  • How open source tech is changing the world

    Open source software (OSS) has been around for some time now, yet the benefits it can offer to a business are often overlooked.

    Open source is software in which the source code that was used to create the program is freely available for the public to view, edit, transform and redistribute. As such, any type of software program can be open source, including and not limited to operating systems (eg, Linux), databases (eg, PostgreSQL), applications (eg, OpenOffice.org), games and programming languages (eg, Python).

    OSS is identified by the type of licence it is released under. The licences OSS is released under are very specific and include the Apache 2.0 licence, Microsoft Public Licence and GNU General Public Licence. There may be a few variations; however, most open source licences require that the source code be freely available to everyone and users are free to modify the source code and redistribute the software and derived works at will.

  • How open source can survive the cloud

    Open source has been the backbone of cloud innovation for the past decade, from Linux and MySQL to Kubernetes, Spark, Presto, and MongoDB. But recent developments have thrown a dark cloud over the business model behind open source, and the industry must act now to avert stifling one of its greatest sources of innovation.

    As a co-creator and former project lead for Apache Hive, I know that incentives are critical for an open source ecosystem to thrive. Independent developers need the incentive to contribute their time and skills to open source projects, and those with an entrepreneurial mindset need the incentive to build companies around those projects to help them flourish.

  • Get Great 3D Scans with Open Photogrammetry

    Not long ago, photogrammetry — the process of stitching multiple photographs taken from different angles into a 3D whole — was hard stuff. Nowadays, it’s easy. [Mikolas Zuza] over at Prusa Printers, has a guide showing off cutting edge open-source software that’s not only more powerful, but also easier to use. They’ve also produced a video, which we’ve embedded below.

    Basically, this is a guide to using Meshroom, which is based on the AliceVision photogrammetry framework. AliceVision is a research platform, so it’s got tremendous capability but doesn’t necessarily focus on the user experience. Enter Meshroom, which makes that power accessible.

  • InfluxData charts new path for time series databases

    At Google NEXT this week, Google is introducing its own strategy for accommodating open source platforms. Rather than compete with its own implementations, it is making them first-class citizens on GCP with native integration to its own cloud management infrastructure. InfluxData, the creator of one of the most popular open source time series databases, has signed on. It occurs as time series databases are starting to crawl out from behind the shadows. We'll be reviewing this more deeply next week in our postmortem on the event.

  • Microsoft Office vs OpenOffice vs LibreOffice: Which one is better? [Ed: How a dedicated Microsoft propaganda site covered the Free software rivals to Microsoft Office]

    Microsoft Office remains to be a powerful platform among the office suits, however, with the rise of free alternative office suites like LibreOffice and Apache’s OpenOffice to Microsoft Office, the question arises if you have to switch from Microsoft Office to the open source Office suites. Both the Microsoft Office and Open source Office suits have their pros and cons, and one of the biggest decision you may have to face is to pick one among them.

    Are you planning to upgrade from your old Office suite or looking out for a changeover to new Office suites? Well, choosing between a commercially licensed Microsoft Office suite and an open-source platform like LibreOffice or an OpenOffice purely depends on how it fits your needs.

  • ColorID discusses how open-source solutions can enable more options for campuses

    In a recent addition to the company’s tech article series, ColorID’s David Stallsmith discusses the options at a university’s disposal should it decide to pursue open-source hardware and software solutions. Opting for open-source solutions can offer an alternative to the traditional practice of opting for card system vendor solutions and the comprehensive ecosystems that come with, says Stallsmith.

    “Many organizations purchase these solutions exclusively from their system providers, but many others chose to acquire some applications and services from third-party suppliers,” he explains. “This latter arrangement allowed them to prioritize their options for the applications they needed according to price, features, brands and support.”

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
