  • Databases Microconference Accepted into 2019 Linux Plumbers Conference

    We are pleased to announce that the Databases Microconference has been accepted into the 2019 Linux Plumbers Conference! Linux plumbing is heavily important to those who implement databases and their users who expect fast and durable data handling.

    Durability is a promise never to lose data after advising a user of a successful update, even in the face of power loss. It requires a full-stack solution from the application to the database, then to Linux (filesystem, VFS, block interface, driver), and on to the hardware.

    Fast means getting a database user a response in less that tens of milliseconds, which requires that Linux filesystems, memory and CPU management, and the networking stack do everything with the utmost effectiveness and efficiency.

  • Ten Years of "Linux in the GNU/South": an Overview of SELF 2019

    The tenth annual SouthEast LinuxFest (SELF) was held on the weekend of June 14–16 at the Sheraton Charlotte Airport Hotel in Charlotte, North Carolina. Still running strong, SELF serves partially as a replacement for the Atlanta Linux Showcase, a former conference for all things Linux in the southeastern United States. Since 2009, the conference has provided a venue for those living in the southeastern United States to come and listen to talks by speakers who all share a passion for using Linux-based operating systems and free and open-source software (FOSS). Although some of my praises of the conference are not exclusive to SELF, the presence of such a conference in the "GNU/South" has the long-term potential to have a significant effect on the Linux and FOSS community.

    Despite facing several challenges along the way, SELF's current success is the result of what is now ten years of hard work by the conference organizers, who currently are led by Jeremy Sands, one of the founding members of the conference. Scanning through the materials for SELF 2019, however, there is no mention that this year's conference marked a decade of "Linux in the GNU/South". It actually wasn't until the conference already was over that I realized this marked SELF's decennial anniversary. I initially asked myself why this wasn't front and center on event advertisements, but looking back on SELF, neglecting questions such as "how long have we been going?" and instead focusing on "what is going on now?" and "where do we go from here?" speaks to the admirable spirit and focus of the conference and its attendees. This focus on the content of SELF rather than SELF itself shows the true passion for the Linux community rather than any particular organization or institution that benefits off the community.

    Another element worthy of praise is SELF's "all are welcome" atmosphere. Whether attendees were met with feelings of excitement to return to an event they waited 362 days for or a sense of apprehension as they stepped down the L-shaped hall of conference rooms for the first time, it took little time for the contagious, positive energy to take its effect. People of all ages and all skill levels could be seen intermingling and enthusiastically inviting anybody who was willing into their conversations and activities. The conference talks, which took all kinds of approaches to thinking about and using Linux, proved that everybody is welcome to attend and participate at the event.

  • Linux Security Summit North America 2019: Schedule Published

    This year, there are some changes to the format of LSS-NA. The summit runs for three days instead of two, which allows us to relax the schedule somewhat while also adding new session types. In addition to refereed talks, short topics, BoF sessions, and subsystem updates, there are now also tutorials (one each day), unconference sessions, and lightning talks.

  • EuroPython 2019: Mobile Conference App available
  • Invitation to the EuroPython Society General Assembly 2019

    We would like to invite all EuroPython attendees and EuroPython Society (EPS) members to attend this year’s EPS General Assembly (GA), which we will run as in-person meeting at the upcoming EuroPython 2019, held in Basel, Switzerland from July 8 - 14.

4 open source Android apps for writers

OSS

While I'm of two minds when it comes to smartphones and tablets, I have to admit they can be useful. Not just for keeping in touch with people or using the web but also to do some work when I'm away from my computer.

For me, that work is writing—articles, blog posts, essays for my weekly letter, e-book chapters, and more. I've tried many (probably too many!) writing apps for Android over the years. Some of them were good. Others fell flat.

Here are four of my favorite open source Android apps for writers. You might find them as useful as I do.

Statement by The Apache Software Foundation Board of Directors

Filed under
OSS

It is with a mix of sadness and appreciation that the ASF Board accepted the resignations of Board Member Jim Jagielski, Chairman Phil Steitz, and Executive Vice President Ross Gardler last month.

As an ASF co-founder, Jim has held every officer position since the Foundation’s incorporation, with the exception of a one-year break in 2018. He has played a substantial role in the development and success of the organization and is a recognized advocate of Open Source at the developer and corporate levels.

An ASF Member since 2005, Phil was instrumental in the adoption, growth, and ubiquity of Apache Java projects across many industries, most visibly financial services. He served as Vice President Apache Commons for four years, and as ASF Chairman August 2017 - May 2019.

Ross has been championing The Apache Way to governments, corporations, and educational institutions for nearly two decades. Since becoming an ASF Member in 2005, he served as Vice President of Community Development (2009-2012), ASF Director and President (2015-2016), and ASF Executive Vice President October 2016 - May 2019.

We laud their contributions to many of the ASF's achievements over the past two decades [1]. Their motivation, vision, and passion is truly inspiring. Whilst we will greatly miss their day-to-day leadership at the executive level, we are heartened that the Foundation will continue to benefit through their participation as ASF Members.

  • MIT Researchers Open-Source AutoML Visualization Tool ATMSeer

    A research team from MIT, Hong Kong University, and Zhejiang University has open-sourced ATMSeer, a tool for visualizing and controlling automated machine-learning processes.

    Solving a problem with machine learning (ML) requires more than just a dataset and training. For any given ML tasks, there are a variety of algorithms that could be used, and for each algorithm there can be many hyperparameters that can be tweaked. Because different values of hyperparameters will produce models with different accuracies, ML practitioners usually try out several sets of hyperparameter values on a given dataset to try to find hyperparameters that produce the best model. This can be time-consuming, as a separate training job and model evaluation process must be conducted for each set. Of course, they can be run in parallel, but the jobs must be setup and triggered, and the results recorded. Furthermore, choosing the particular values for hyperparameters can involve a bit of guesswork, especially for ones that can take on any numeric value: if 2.5 and 2.6 produce good results, maybe 2.55 would be even better? What about 2.56 or 2.54?

  • DoD’s Joint AI Center to open-source natural disaster satellite imagery data set

    As climate change escalates, the impact of natural disasters is likely to become less predictable. To encourage the use of machine learning for building damage assessment this week, Carnegie Mellon University’s Software Engineering Institute and CrowdAI — the U.S. Department of Defense’s Joint AI Center (JAIC) and Defense Innovation Unit — open-sourced a labeled data set of some of the largest natural disasters in the past decade. Called xBD, it covers the impact of disasters around the globe, like the 2010 earthquake that hit Haiti.

    “Although large-scale disasters bring catastrophic damage, they are relatively infrequent, so the availability of relevant satellite imagery is low. Furthermore, building design differs depending on where a structure is located in the world. As a result, damage of the same severity can look different from place to place, and data must exist to reflect this phenomenon,” reads a research paper detailing the creation of xBD.

    [...]

    xBD includes approximately 700,000 satellite images of buildings before and after eight different kinds of natural disasters, including earthquakes, wildfires, floods, and volcanic eruptions. Covering about 5,000 square kilometers, it contains images of floods in India and Africa, dam collapses in Laos and Brazil, and historic deadly fires in California and Greece.

    The data set will be made available in the coming weeks alongside the xView 2.0 Challenge to unearth additional insights from xBD, coauthor and CrowdAI machine learning lead Jigar Doshi told VentureBeat. The data set collection effort was informed by the California Air National Guard’s approach to damage assessment from wildfires.

  • Open-source textbooks offer free alternative for UC Clermont students

    Some UC Clermont College students are avoiding paying hundreds of dollars for textbooks — and getting the content for free — thanks to online open-source textbooks, a growing trend among faculty at the college and throughout higher education.

    UC Clermont Dean Jeff Bauer, who is also a professor of business, said the benefits of open textbooks are many. “All students have the book on the first day of class, it saves them a lot of money, and the information can be accessed anywhere, anytime, without carrying around a heavy textbook,” Bauer said. “They don’t need to visit the bookstore before or after each semester to buy or sell back books, either.”

  • Successful open-source RISC-V microcontroller launched through crowdfunding

    X-FAB Silicon Foundries, together with crowd-sourcing IC platform partner Efabless Corporation, launched the first-silicon availability of the Efabless RISC-V SoC reference design. This open-source semiconductor project went from start of design to tape-out in less than three months employing the Efabless design flow produced on open-source tools. The mixed-signal SoC, called Raven, is based on the community developed ultra-low power PicoRV32 RISC-V core. Efabless has bench-tested the Raven at 100MHz, and based on simulations, the solution should operate at up to 150MHz.

  • Open Hardware: Open-Source MRI Scanners Could Bring Enormous Cost Savings

    Wulfsberg explore the possibilities of open source MRI scanning. As open-source technology takes its place around the world—everywhere from makerspaces to FabLabs, users on every level have access to design and innovation. In allowing such access to MRI scanning, the researchers realize the potential for ‘technological literacy’ globally—and with MRIs specifically, astronomical sums could be saved in healthcare costs.

    The authors point out that medical technology is vital to the population of the world for treating not only conditions and illnesses, but also disabilities. As so many others deeply involved in the world of technology and 3D printing realize, with greater availability, accessibility, and affordability, huge strides can be made to improve and save lives. Today, with so many MRI patents expiring, the technology is open for commercialization.

Good List of 5 Open Source Remote Desktop Software

Filed under
OSS

First, you should know that in order for two machines to communicate together, they need what’s known as a “protocol”. A remote desktop protocol is a way of transferring the instructions from one computer to another so that you can graphically control the other system.

There are many famous remote desktop protocols, such as RDP (Remote Desktop Protocol) which is a proprietary protocol designed by Microsoft and implemented in its Windows operating system, and the VNC (Virtual Network Computing) protocol, which is a free and open source protocol to do the same task, and you can additionally connect to the remote host via SSH, NX protocols and others.

Now, away from protocols, you’ll of course need a program to access the remote desktop. In general, people are using the proprietary TeamViewer program to do that. But there are many other open source alternatives to TeamViewer that you can use.

8 Top Ubuntu server Web GUI Management Panels

Ubuntu Server with command-line interface might sound little bit wired to newbies because of no previous familiarization. Thus, if you are new to Ubuntu Linux server running on your local hardware or some Cloud hosting and planning to install some Linux Desktop Graphical environment (GUI) over it; I would like to recommend don’t, until and unless you don’t have supported hardware. Instead, think about free and open-source Ubuntu server Web GUI Management panels. Moreover, for a moment, you can think about Desktop Graphical environment for your local server but if you have some Linux cloud hosting server, never do it. I am saying this because Ubuntu or any other Linux server operating systems are built to run on low hardware resources, thus even old computer/server hardware can easily handle it. GUI means more RAM and hard disk storage space. Read more

Ubuntu 18.10 Cosmic Cuttlefish reaches end of life on Thursday, upgrade now

Canonical, earlier this month, announced that Ubuntu 18.10 Cosmic Cuttlefish will be reaching end-of-life status this Thursday, making now the ideal time to upgrade to a later version. As with all non-Long Term Support (LTS) releases, 18.10 had nine months of support following its release last October. When distributions reach their end-of-life stage, they no longer receive security updates. While you may be relatively safe at first, the longer you keep running an unpatched system, the more likely it is that your system will become compromised putting your data at risk. If you’d like to move on from Ubuntu 18.10, you’ve got two options; you can either perform a clean install of a more up-to-date version of Ubuntu or you can do an in-place upgrade. Read more
