  • Software Defined Drones and the Path to Standardization and Scale in the Drone Industry

    Sartori is the co-founder of Auterion – they’re the Red Hat of the drone industry, serving as a distributor and enabler for open source software for drones. He’s a proponent of open source, and a believer that open source software is the key to scalability in the drone industry. There’s data and history to support the idea. As drone manufacturing giant DJI is often compared to Apple, open source drones are frequently compared to Android – and Sartori points out that Android is based on open source Linux, and as more than 87 percent of phones are now Android, that makes it the most used software in the world.

  • ITP Renewables releases free open-source modelling platform for the energy transition

    ITP Renewables has released Version 1 of open-CEM, a free of charge open source modelling tool for the National Electricity Market (NEM). The tool can be used by policy makers, project developers, investors and the public to run scenarios of the development of the NEM out to 2050. The project’s aim is to provide a transparent and well-informed analysis of technology and policy options for the NEM as Australia proceeds through the energy transition.

    Open-CEM was developed in conjunction the Centre for Energy and Environmental Markets at the University of New South Wales (UNSW), the Energy Transition Hub at the University of Melbourne, software developers ThoughtWorks and the US Strategy Energy Analysis Center of the National Renewable Energy Laboratory.

  • Arcadia Fund grant to support open-source publishing across UC campuses

    The Educopia Institute and California Digital Library, or CDL, received a $2.2 million grant in August in support of the Next Generation Library Publishing project, or Next Gen.

    The grant was bestowed by the Arcadia Fund, a charity that supports environmental, cultural heritage and open-access projects. The Next Gen project is said to enhance the UC system’s open-access publishing infrastructure by providing noncommercial tools that support the dissemination of knowledge, according to a CDL press release.

  • OpenLeg – The Open Source Robot Leg

    There’s an old saying about standing on the shoulders of giants, but how about doing so with an open source leg? Well, your robots might do so at least, thanks to OpenLeg, a new open source project for building robot legs. Created by [Joey Byrnes], this started out as a senior project for a course at the University of Illinois. The idea is to create a robot leg that others can use to build four-legged robots that can amble around the neighborhood, much like those built by Boston Dynamics.

  • New microscopes unravel the mysteries of brain organization

    The secret of capturing exquisite brain images with a new generation of custom-built microscopes is revealed today in Nature Methods. The new microscopes, known as mesoSPIMs, can image the minute detail of brain tissue down to individual neurons that are five times thinner than a human hair, and can uncover the 3D anatomy of entire small organs, faster than ever before. MesoSPIMs provide new insights into brain and spinal cord organization for researchers working to restore movement after paralysis or to investigate neuronal networks involved in cognition, pleasure, or drug addiction.

  • New open-source microscope may help paralysis patients

    Scientists have developed a new generation of custom-built microscopes that significantly improve brain tissue imaging, an advance that could help find better treatment for patients with paralysis.

    The microscopes, known as mesoSPIMs—short for 'mesoscale selective plane-illumination microscopes'—can image brain tissues down to the minute details of individual neurons which are five times thinner than a human hair, the study noted.

    The researchers added that they can uncover the 3D anatomy of entire small organs, faster than ever before using the new microscope.

=== Vagrant Images ===

FreeBSD/amd64 images are available on the Hashicorp Atlas site, and can
be installed by running:

    % vagrant init freebsd/FreeBSD-12.1-RC2
    % vagrant up

=== Upgrading ===

The freebsd-update(8) utility supports binary upgrades of amd64 and i386
systems running earlier FreeBSD releases.  Systems running earlier
FreeBSD releases can upgrade as follows:

	# freebsd-update upgrade -r 12.1-RC2

During this process, freebsd-update(8) may ask the user to help by
merging some configuration files or by confirming that the automatically
performed merging was done correctly.

	# freebsd-update install

The system must be rebooted with the newly installed kernel before
continuing.

	# shutdown -r now

After rebooting, freebsd-update needs to be run again to install the new
userland components:

	# freebsd-update install

It is recommended to rebuild and install all applications if possible,
especially if upgrading from an earlier FreeBSD release, for example,
FreeBSD 11.x.  Alternatively, the user can install misc/compat11x and
other compatibility libraries, afterwards the system must be rebooted
into the new userland:

	# shutdown -r now

Finally, after rebooting, freebsd-update needs to be run again to remove
stale files:

	# freebsd-update install

Games: Stellaris, Crusader Kings III and More

  • Stellaris: Federations and Stellaris: Lithoids Species Pack announced at PDXCON

    PDXCON is now in full swing and the announcement are being handed out like candy. First up, Paradox Interactive and Paradox Development Studio have announced Stellaris: Federations and Stellaris: Lithoids Species Pack.

  • Crusader Kings III announced for release next year, to be more welcoming to new players

    As I suggested they would when setting Crusader Kings II permanently free (but not the DLC), Paradox Interactive have announced Crusader Kings III. "Crusader Kings III is a grand medieval simulator where you are free to live out any plausible ruler fantasy that we could think of - but not without challenge." says Henrik Fåhraeus, the Game Director. "Seeing its predecessor explode in popularity was very satisfying, especially considering that user friendliness was never our primary goal. Now we have a chance to address an even larger audience."

  • Prison Architect - Psych Ward: Warden's Edition expansion announced (plus another coming)

    I think we all saw this coming when Paradox Interactive picked up the rights to Prison Architect, with Double Eleven taking on further development. The first proper DLC has been announced at PDXCON named Prison Architect - Psych Ward: Warden's Edition. Psych Ward was previously a console exclusive DLC, so it's good to see it make it onto PC. However, it does include new added features not in the original DLC and it will launch along side a free content update for everyone. It's not exactly a small pack either, it actually sounds like it's going to be adding quite a bit to the game. Paradox also gave it a release date of November 21, so you won't exactly have long to wait to really find out.

  • BATTLETECH: Heavy Metal brings more classic 'Mechs and new weapon systems, releasing in November

    Even more news from PDXCON! Harebrained Schemes and Paradox Interactive have now properly announced the BATTLETECH: Heavy Metal expansion to bring more destruction.

  • Hearts of Iron IV: La Résistance expansion and a significant free update announced

    Paradox Development Studio and Paradox Interactive are expanding another of their grand-scale strategy games, with Hearts of Iron IV: La Résistance announced during PDXCON. Not just that, as they usually do they also confirmed a "significant" free content update will be released to all players. The free update will include a reworking of the resistance system, interface improvements to battleplans and air operations plus many other "quality of life improvements".

  • Bioshock 1 & 2 | Linux Gaming | Ubuntu 19.04 | Steam Play

    Bioshock 1 & 2 running through Steam play.

  • Continuing the Counter-Strike 20th anniversary Valve put out skins, plus a possible Operation and update coming

    After starting off the celebration for Counter-Strike turning 20 back in June with the retro version of Dust II, Valve have now added a refreshed version of the map Cache and a themed Weapon Case and Sticker Capsule. We're expecting some bigger updates to come but let's go over what they've already done. [...] VNN's Tyler McVicker also released another of his highly speculative videos talking about lots of other things that could be pointing to a new operation. With a possible update coming that may include: custom Danger Zone modes, a new Danger Zone map, new Danger Zone weapons, co-op missions, hats and other wearable items, player taunts and more being speculated on. I personally hope Valve do put out a big update, since their celebration so far has been a bit lacklustre. An old map, a refreshed map and some skins you have to pay for. Not exactly big or exciting really so far. Speaking personally again, I'm still very much enjoying Danger Zone so if they do expand it again I will be quite pleased.
