  • 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.”

Security Leftovers

  • Researchers Build App That Kills To Highlight Insulin Pump Exploit

    By now the half-baked security in most internet of things (IOT) devices has become a bit of a running joke, leading to amusing Twitter accounts like Internet of Shit that highlight the sordid depth of this particular apathy rabbit hole. And while refrigerators leaking your gmail credentials and tea kettles that expose your home networks are entertaining in their own way, it's easy to lose sight of the fact that the same half-assed security in the IOT space also exists on most home routers, your car, your pacemaker, and countless other essential devices and services your life may depend on. Case in point: just about two years ago, security researchers discovered some major vulnerabilities Medtronic's popular MiniMed and MiniMed Paradigm insulin pumps. At a talk last year, they highlighted how a hacker could trigger the pumps to either withhold insulin doses, or deliver a lethal dose of insulin remotely. But while Medtronic and the FDA warned customers about the vulnerability and issued a recall over time, security researchers Billy Rios and Jonathan Butts found that initially, nobody was doing much to actually fix or replace the existing devices. [...] And of course that's not just a problem in the medical sector, but most internet-connected tech sectors. As security researcher Bruce Schneier often points out, it's part of a cycle of dysfunction where the consumer and the manufacturer of a flawed product have already moved on to the next big purchase, often leaving compromised products, and users, in a lurch. And more often than not, when researchers are forced to get creative to highlight the importance of a particular flaw, the companies in question enjoy shooting the messenger.

Games: Dota Underlords and Stadia

  • Dota Underlords has another update out, this one changes the game quite a lot

    Valve continue to tweak Dota Underlords in the hopes of keeping players happy, this mid-Season gameplay update flips quite a few things on their head. I like their sense of humour, with a note about them removing "code that caused crashes and kept code that doesn't cause crashes". There's a few smaller changes like the addition of Loot Round tips to the Season Info tab, the ability to change equipped items from the Battle Pass and some buffs to the amount XP awarded for your placement in matches and for doing the quests. Meaning you will level up the Battle Pass faster.

  • Interested in Google's Stadia game streaming service? We have a few more details now

    With Google's game streaming service Stadia inching closer, we have some more information to share about it. Part of this, is thanks to a recent AMA (Ask Me Anything) they did on Reddit. I've gone over what questions they answered, to give you a little overview. Firstly, a few points about the Stadia Pro subscription: The Pro subscription is not meant to be like a "Netflix for Games", something people seem to think Stadia will end up as. Google said to think of it more like Xbox Live Gold or Playstation Plus. They're aiming to give Pro subscribers one free game a month "give or take". If you cancel Stadia Pro, you will lose access to free games claimed. However, you will get the previously claimed games back when you re-subscribe but not any you missed while not subscribed. As for Stadia Base, as expected there will be no free games included. As already confirmed, both will let you buy games as normal.

LabPlot has got some beautifying and lots of datasets

Hello everyone! The second part of this year's GSoC is almost over, so I was due to let you know the progress made in the last 3 weeks. I can assure you we haven't lazed since then. I think I managed to make quite good progress, so everything is going as planned, or I could say that even better. If you haven't read about this year's project or you just want to go through what has already been accomplished you can check out my previous post. So let's just go through the new things step by step. I'll try to explain the respective feature, and also give examples using videos or screenshots. The first step was to improve the welcome screen and make it easily usable, dynamic, clean and intuitive for users. This step was very important since the welcome screen is what the users will first get in contact with when they start using LabPlot. Read more

  • Weston 7.0 Reaches Alpha With PipeWire, HDCP, EGL Partial Updates & Mores

    Wayland release manager Simon Ser announced the alpha release of the Weston 7.0 reference compositor on Friday that also marks the feature freeze for this Wayland compositor update. Some of the major changes to Weston 7.0 include HDCP content protection support, better documentation, new debugging and logging framework support, and the just-added PipeWire plug-in for remote streaming. There are also less prominent additions like EGL partial update support, various DRM compositor back-end restructuring, build system updates, and a variety of libweston updates.

  • RadeonSI Gallium3D Driver Adds Navi Wave32 Support

    One of the new features to the RDNA architecture with Navi is support for single cycle issue Wave32 execution on SIMD32. Up to now the RadeonSI code was using just Wave64 but now there is support in this AMD open-source Linux OpenGL driver for Wave32. Well known AMD open-source developer Marek Olšák landed this Wave32 support on Friday for the RadeonSI driver. The Wave32 support landed over several commits to Mesa 19.2-devel and is enabled for vertex, geometry, and tessellation shaders. Wave32 isn't enabled for pixel shaders but rather Wave64. Additionally, Wave32 isn't yet enabled for compute shaders due to Piglit OpenGL test case failures.
