  • SQLite Release 3.28.0
  • SQLite 3.28 Released With More Feature Additions, Performance Enhancements

    SQLite 3.28 is now the latest version of this widely-used, embed-friendly cross-platform database library.

    As is the case for most SQLite releases, new features and performance enhancements are the principle changes. SQLite 3.28 presents enhanced window functions, enhancements to its TCL interface, various CLI improvements, new API additions, security improvements to its tokenizer, more robust handling against corrupt database files, and various fixes.

  • Gnuastro 0.9 released

    I am happy to announce the 9th stable release of GNU Astronomy
    Utilities (Gnuastro).

    Gnuastro is an official GNU package consisting of various command-line
    programs and library functions for the manipulation and analysis of
    (astronomical) data. All the programs share the same basic
    command-line user interface (modeled on GNU Coreutils). For the full
    list of Gnuastro's library, programs, and a comprehensive general
    tutorial (recommended place to start using Gnuastro), please see the
    links below respectively:

    https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-library.html
    https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-programs-list.html
    https://www.gnu.org/s/gnuastro/manual/html_node/General-program-usage-tutorial.html

    Many features have been added and Gnuastro has become much more stable
    with the many bugs that were found and fixed (see [1], below). The most
    interesting new feature may be that Gnuastro now also installs scripts
    (with this naming convention: `astscript-*'). Since Gnuastro's
    programs are designed to be highly modular, they are relatively
    low-level. With this new feature, it is now very easy to include
    common higher-level operations within Gnuastro also, for example to
    call multiple programs together, or use a single program's outputs in
    a special way. With version 0.9, only one script is installed (as
    described in [1]), but because of their high-level nature, we expect
    many more to be added soon. If you commonly run several Gnuastro
    programs together for a certain operation, please share it with us so
    we add it as a script for everyone to use.

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.

KDE Cantor - Sing me some math

Filed under
KDE
Software
Sci/Tech

It's a song, but it needs refinement. Cantor seems like a clever piece of software, but it lacks refinement and sophistication to match its own goals. I did only test Octave, but I think my findings are pretty indicative. After all, if there were issues with one backend, whatever they are, they need to be fixed. And these weren't trivial issues, either. Slow performance, memory and CPU noise, frozen interface, bad-looking figures.

The configuration also needs to be improved. All in all, it's very difficult doing what Cantor tries, so the idea is really cool. But it seems to be a complex task, and at the moment, it brings more woes than benefits. I'd like to see a smoother integration, and a clever wizard that lets you add backends. Maybe a smart clipboard to share code with other programs. I'd expect a fully HW-accelerated graphics module, so everything responds fast and looks peachy. Finally, Cantor mustn't work any worse than the native engines it represents, because it invalidates its own purpose by doing that (or rather not doing that, hi hi). At the moment, it's a raw product, and it needs a lot of fixes. But me likey, so I will be testing in the future. Unique software, here I go.

The Raspberry Pi Cluster from Outer Space

Hardware
Sci/Tech

We see a lot of weird and esoteric stuff here at Hackaday, but even by our standards, Bell Lab’s Plan 9 operating system is an oddball. Named after the science fiction film Plan 9 from Outer Space, it was designed to extend the UNIX “everything is a file” mentality to the network. It envisioned a future where utilizing the resources of another computer would be as easy as copying a file. But as desktop computers got more powerful the idea seemed less appealing, and ultimately traditional operating systems won out. Of course, that doesn’t mean you still can’t play around with it.

Astronomy Software by Any Other Name

Filed under
Software
Sci/Tech

In this article, I introduce another option available for the astronomers out there—specifically, Cartes du Ciel, also known as SkyChart. Similar to other larger astronomy programs, you can use SkyChart from the desktop to the observatory.

SkyChart probably won't be available in your distribution's package management system, so you'll need to go to the main website to download it. DEB, RPM and TAR files are available, so you should be able to use it for just about any distribution. Downloads also are available for other operating systems and for other hardware. You even can download a version to run on a Raspberry Pi.

When you first start Cartes du Ciel, you'll be asked where on the globe your observatory is located.

  • Hardware Review - The ZaReason Virtus 9200 Desktop
  • Chrome OS 76 will disable Crostini Linux backups by default
    Essentially, this is still a work in progress feature. And I shouldn’t be terribly surprised by that, even though in my experience, the functionality hasn’t failed me yet. That’s because we know that the Chromium team is considering on a way to backup and restore Linux containers directly from the Files app on a Chromebook. That proposal is targeted for Chrome OS 78, so this gives the team more time to work that out, as well as any other nits that might not be quite right with the current implementation.
  • Andrei Lisita: Something to show for
    Unfortunately along with the progress that was made we also encountered a bug with the NintendoDS core that causes Games to crash if we attempt to load a savestate. We are not yet 100% sure if the bug is caused by my changes or by the NintendoDS core itself. I hope we are able to fix it by the end of the summer although I am not even sure where to start since savestates are working perfectly fine with other cores. Another confusing matter about this is that the Restart/Resume Dialog works fine with the NintendoDS core and it also uses savestates. This led me to believe that perhaps cores can be used to load savestates only once, but this can’t be the problem since we re-instantiate the core every time we load a savestate. In the worst case we might just have to make a special case for the NintendoDS core and not use savestates with it, except for the Resume/Restart dialog. This would sadden me deeply since there are plenty of NintendoDS games which could benefit from this feature.

  • 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.”

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.
