SQLite 3.28.0 and Gnuastro 0.9 Released

Sci/Tech
  • 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.

GNU GPLv3 At The Center Of The Black Hole Image

Sci/Tech

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

Filed under

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.

Official x86 Zhaoxin Processor Support Is Coming With Linux 5.3

Zhaoxin is the company producing Chinese x86 CPUs created by a joint venture between VIA and the Shanghai government. The current Zhaoxin ZX CPUs are based on VIA's Isaiah design and making use of VIA's x86 license. With the Linux 5.3 kernel will be better support for these Chinese desktop x86 CPUs. Future designs of the Zhaoxin processors call for 7nm manufacturing, PCI Express 4.0, DDR5, and other features to put it on parity with modern Intel and AMD CPUs. It remains to be seen how well that will work out, but certainly seems to be moving along in the desktop/consumer space for Chinese-built x86 CPUs while in the server space there's the Hygon Dhyana EPYC-based processors filling the space for Chinese servers.

  • Go and FIPS 140-2 on Red Hat Enterprise Linux

    Red Hat provides the Go programming language to Red Hat Enterprise Linux customers via the go-toolset package. If this package is new to you, and you want to learn more, check out some of the previous articles that have been written for some background. The go-toolset package is currently shipping Go version 1.11.x, with Red Hat planning to ship 1.12.x in Fall 2019. Currently, the go-toolset package only provides the Go toolchain (e.g., the compiler and associated tools like gofmt); however, we are looking into adding other tools to provide a more complete and full-featured Go development environment. In this article, I will talk about some of the improvements, changes, and exciting new features for go-toolset that we have been working on. These changes bring many upstream improvements and CVE fixes, as well as new features that we have been developing internally alongside upstream.

  • Check your password security with Have I Been Pwned? and pass

    Password security involves a broad set of practices, and not all of them are appropriate or possible for everyone. Therefore, the best strategy is to develop a threat model by thinking through your most significant risks—who and what you are protecting against—then model your security approach on the activities that are most effective against those specific threats. The Electronic Frontier Foundation (EFF) has a great series on threat modeling that I encourage everyone to read. In my threat model, I am very concerned about the security of my passwords against (among other things) dictionary attacks, in which an attacker uses a list of likely or known passwords to try to break into a system. One way to stop dictionary attacks is to have your service provider rate-limit or deny login attempts after a certain number of failures. Another way is not to use passwords in the "known passwords" dataset.

  • The future of OpenStack?

    Before we can answer these questions, let’s take a look at its past to give some context. Since its original release in 2010 as a joint venture by Rackspace and NASA, and its subsequent spin-off into a separate open source foundation in 2012, OpenStack has seen growth and hype that was almost unparalleled. I was fortunate enough to attend the Paris OpenStack Summit in 2014, where Mark Collier was famously driven onto stage for a keynote in one of the BMW electric sports cars. The event was huge and was packed with attendees and sponsors – almost every large technology company you can think of was there. Marketing budget had clearly been splurged in a big way on this event with lots of pizazz and fancy swag to be had from the various vendor booths. Cycle forward 4 years to the next OpenStack Summit I attended – Vancouver in May 2018. This was a very different affair – most of the tech behemoths were no longer sponsoring, and while there were some nice pieces of swag for attendees to take home, it was clear that marketing budgets had been reduced as the hype had decreased. There were less attendees, less expensive giveaways, but that ever-present buzz of open source collaboration that has always been a part of OpenStack was still there. Users were still sharing their stories, and developers and engineers were sharing their learnings with each other, just on a slightly smaller scale.

Glen Barber: Statement regarding employment change and roles in the [FreeBSD] Project

Dear FreeBSD community:

As I have a highly-visible role within the community, I want to share
some news.  I have decided the time has come to move on from my role
with the FreeBSD Foundation, this Friday being my last day.  I have
accepted a position within a prominent company that uses and produces
products based on FreeBSD.

My new employer has included provisions within my job description that
allow me to continue supporting the FreeBSD Project in my current
roles, including Release Engineering.

There are no planned immediate changes with how this pertains to my
roles within the Project and the various teams of which I am a member.

FreeBSD 11.3 and 12.1 will continue as previously scheduled, with no
impact as a result of this change.

I want to thank everyone at the FreeBSD Foundation for providing the
opportunity to serve the FreeBSD Project in my various roles, and their
support for my decision.

I look forward to continue supporting the FreeBSD Project in my various
roles moving forward.

Glen
