  • RADV's Iffy 16-bit Integer Support Merged Into Mesa

    Just days after the patches were published for enabling 16-bit integers within shaders for the RADV driver, this Radeon Vulkan driver code has been merged.

    The code came out last week by Valve developer Samuel Pitoiset for enabling shaderInt16, the capability allowing 16-bit signed/unsigned integers within the shader code.

  • Mesa Eyeing The Removal Of Autotools Build Support In Favor Of Meson

    For those currently relying upon Autotools for building Mesa3D, the days are numbered and soon will likely need to shift over to their modern Meson build system support.

    For the past year now, Mesa developers have been working on bringing up their Meson build system support for its faster build speeds with Ninja, better cross-platform compatibility, and other benefits. Meson has co-existed with the Autotools (and SCons and Android build systems) support over the past year of Mesa releases, but moving forward they are likely very soon to drop the Autotools support.

  • OpenBSD/NetBSD on FreeBSD using grub2-bhyve

    When I was writing a blog post about the process title, I needed a couple of virtual machines with OpenBSD, NetBSD, and Ubuntu. Before that day I mainly used FreeBSD and Windows with bhyve. I spent some time trying to set up an OpenBSD using bhyve and UEFI as described here. I had numerous problems trying to use it, and this was the day I discovered the grub2-bhyve tool, and I love it!

    The grub2-bhyve allows you to load a kernel using GRUB bootloader. GRUB supports most of the operating systems with a standard configuration, so exactly the same method can be used to install NetBSD or Ubuntu. [...]

A $1, Linux-Capable, Hand-Solderable Processor and Open Source Paramotor Using Quadcopter Tech

Filed under

  • A $1, Linux-Capable, Hand-Solderable Processor

    Over on the EEVblog, someone noticed an interesting chip that’s been apparently flying under our radar for a while. This is an ARM processor capable of running Linux. It’s hand-solderable in a TQFP package, has a built-in Mali GPU, support for a touch panel, and has support for 512MB of DDR3. If you do it right, this will get you into the territory of a BeagleBone or a Raspberry Pi Zero, on a board that’s whatever form factor you can imagine. Here’s the best part: you can get this part for $1 USD in large-ish quantities. A cursory glance at the usual online retailers tells me you can get this part in quantity one for under $3. This is interesting, to say the least.

  • Open Source Paramotor Using Quadcopter Tech

    But not always. The OpenPPG project aims to create a low-cost paramotor with electronics and motors intended for heavyweight multicopters. It provides thrust comparable to gas paramotors for 20 to 40 minutes of flight time, all while being cheaper and easier to maintain. The whole project is open source, so if you don’t want to buy one of their kits or assembled versions, you’re free to use and remix the design into a personal aircraft of your own creation.

    It’s still going to cost for a few thousand USD to get a complete paraglider going, but at least you won’t need to pay hangar fees. Thanks to the design which utilizes carbon fiber plates and some clever hinges, the whole thing folds up into a easier to transport and store shape than traditional paramotors with one large propeller. Plus it doesn’t hurt that it looks a lot cooler.

Linux firewalls: What you need to know about iptables and firewalld

Filed under
Linux

A firewall is a set of rules. When a data packet moves into or out of a protected network space, its contents (in particular, information about its origin, target, and the protocol it plans to use) are tested against the firewall rules to see if it should be allowed through. Here’s a simple example...

Mozilla: Firefox GCC/LLVM Clang Dilemma, September 2018 CA Communication and CfP

Filed under
Moz/FF
  • Fedora Firefox – GCC/CLANG dilemma

    After reading Mike’s blog post about official Mozilla Firefox switch to LLVM Clang, I was wondering if we should also use that setup for official Fedora Firefox binaries.

    The numbers look strong but as Honza Hubicka mentioned, Mozilla uses pretty ancient GCC6 to create binaries and it’s not very fair to compare it with up-to date LLVM Clang 6.

    Also if I’m reading the mozilla bug correctly the PGO/LTO is not yet enabled for Linux, only plain optimized builds are used for now…which means the transition at Mozilla is not so far than I expected.

Security: Quantum Computing and Cryptography, Time to Rebuild Alpine Linux Docker Container

Filed under
Security
  • Quantum Computing and Cryptography

    Quantum computing is a new way of computing -- one that could allow humankind to perform computations that are simply impossible using today's computing technologies. It allows for very fast searching, something that would break some of the encryption algorithms we use today. And it allows us to easily factor large numbers, something that would break the RSA cryptosystem for any key length.

    This is why cryptographers are hard at work designing and analyzing "quantum-resistant" public-key algorithms. Currently, quantum computing is too nascent for cryptographers to be sure of what is secure and what isn't. But even assuming aliens have developed the technology to its full potential, quantum computing doesn't spell the end of the world for cryptography. Symmetric cryptography is easy to make quantum-resistant, and we're working on quantum-resistant public-key algorithms. If public-key cryptography ends up being a temporary anomaly based on our mathematical knowledge and computational ability, we'll still survive. And if some inconceivable alien technology can break all of cryptography, we still can have secrecy based on information theory -- albeit with significant loss of capability.

    At its core, cryptography relies on the mathematical quirk that some things are easier to do than to undo. Just as it's easier to smash a plate than to glue all the pieces back together, it's much easier to multiply two prime numbers together to obtain one large number than it is to factor that large number back into two prime numbers. Asymmetries of this kind -- one-way functions and trap-door one-way functions -- underlie all of cryptography.

If recent research is any indication, artificial intelligence (AI) has a bright future in medicine. Nvidia developed an AI system that can generate synthetic scans of brain cancer. Google subsidiary DeepMind has demonstrated a machine learning algorithm that can recommend treatment for more than 50 eye diseases with 94 percent accuracy. And in newly published research, New York University (NYU) showed how AI might aid in lung cancer diagnosis.

A paper today published in the journal Nature Medicine (“Classification and mutation prediction from non-small cell lung cancer histopathology images using deep learning”) describes how a team of NYU researchers retrained Google’s Inception v3, an open source convolutional neural network architected for object identification, to detect certain forms of lung cancers with 97 percent accuracy.

  • What Subset Games (FTL, Into the Breach) think of Valve's Steam Play

    Subset Games [Official Site] are a developer I was especially keen to speak to about Valve's Steam Play system, since Into the Breach is included as a white-listed game by Valve even though they're working on a Linux version.

    Into the Breach is an interesting turn-based strategy game about the remnants of human civilization being threatened by gigantic creatures breeding beneath the earth. They confirmed back in early August that Into the Breach's Linux version was in "active development", so I thought their viewpoint might be quite interesting given the situation.

    They first made it clear they are doing a Linux version, then their programmer Mathew expanded on it a bit.

  • Overwatch Players Using Linux Get Accidentally Banned

    Overwatch is definitely one of the best FPS games around. Even despite the fact that is has been out for over 2 years now, it remains highly popular due to its varied roster of characters and the team-based mechanics. While everything hasn’t been smooth sailing, the game has also largely avoided any major issues as it develops further.

    In a report via PCGamesN though, Linux users of the game had a nasty surprise after they found their Overwatch accounts had been permanently banned.

  • Blizzard Throws Permanent Bans For Overwatch Players Using Linux

    Well, this is quite an interesting situation the players of Overwatch have found themselves.

    It seems like Overwatch players who have been using the Linux operating system to play Blizzard’s hero shooter game have now been banned, like permanently.

    Just recently when bans took place, players found out that their choice of OS was the reason for such bans. There is a lot of unrest among the community as fans are not too happy with this situation, they have been pushed into.

    As you may know that Overwatch has been playable on Linux for quite some time now and fans have been using this opportunity to play using, Linux operating system.

    There are many compelling reasons to use open source software, where the code behind an app is free for anyone to view or contribute to. There's the obvious benefit that it's free to use.

And it may have ethical appeal over an app built by, say, a multinational corporation. This in mind, here are 10 of the best open source alternatives to the software we use on our computers every day.

  • Epic Clock Clocks The Unix Epoch
    Admit it: when you first heard of the concept of the Unix Epoch, you sat down with a calculator to see when exactly 2³¹-1 seconds would be from midnight UTC on January 1, 1970. Personally, I did that math right around the time my company hired contractors to put “Y2K Suspect” stickers on every piece of equipment that looked like it might have a computer in it, so the fact that the big day would come sometime in 2038 was both comforting and terrifying. [Forklift] is similarly entranced by the idea of the Unix Epoch and built a clock to display it, at least for the next 20 years or so. Accommodating the eventual maximum value of 2,147,483,647, plus the more practical ISO-8601 format, required a few more digits than the usual clock – sixteen to be exact. The blue seven-segment displays make an impression in the sleek wooden case, about which there is sadly no detail in the build log. But the internals are well documented, and include a GPS module and an RTC. The clock parses the NMEA time string from the satellites and syncs the RTC. There’s a brief video below of the clock in action.
