BSD: OpenBSD/NetBSD on FreeBSD and Upcoming OpenZFS Developer Summit 2018

  • 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

  • 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.

NYU applies open source Google AI to diagnose lung cancer

Filed under
Google
OSS

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.

    It's been a rather turbulent time for Black Riddles Studio, with Crazy Justice [Official Site, Steam] originally being scheduled to release in Early Access in July. I contacted Fig to see if they knew what was going on, who got an answer from Black Riddles for me. First, let's sum up the situation for those not up to speed.

  • 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.

  • The best open source alternatives to your everyday apps

    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. It's arguably more secure (thanks to the many eyes on the source code). It's built solely for the benefit of users. 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.

  • peek – animated GIF screen recorder

    I’m always on the look out for small indispensable utilities that make the Linux experience even better. This week, I’m seeking to garnish support for peek. It’s an unpretentious utility written in Vala. The utility has no delusion of grandeur. But it has qualities that carves out its own niche in the open source world.

    Peek is designed to make short screencasts. It’s not a general purpose screencast application like OBS Studio. Instead, peek captures silent screencasts of part of the screen. Examples of its usage including demonstrating user interface features of software, or creating a visual bug report. The software supports recording in GIF, APNG, WebM and MP4 formats.

Debian Patches for Intel's Defects, Canonical to Fix Ubuntu Security Flaws for a Fee

  • Debian Outs Updated Intel Microcode to Mitigate Spectre V4 and V3a on More CPUs
    The Debian Project released an updated Intel microcode firmware for users of the Debian GNU/Linux 9 "Stretch" operating system series to mitigate two of the latest Spectre vulnerabilities on more Intel CPUs. Last month, on August 16, Debian's Moritz Muehlenhoff announced the availability of an Intel microcode update that provided Speculative Store Bypass Disable (SSBD) support needed to address both the Spectre Variant 4 and Spectre Variant 3a security vulnerabilities. However, the Intel microcode update released last month was available only for some types of Intel CPUs, so now the Debian Project released an updated version that implements SSBD support for additional Intel CPU models to mitigate both Spectre V4 and V3a on Debian GNU/Linux 9 "Stretch" systems.
  • Announcing Extended Security Maintenance for Ubuntu 14.04 LTS – “Trusty Tahr” [Ed: Canonical looking to profit from security flaws in Ubuntu like Microsoft does in Windows.]
    Ubuntu is the basis for the majority of cloud-based workloads today. With over 450 million public cloud instances launched since the release of Ubuntu 16.04 LTS, a number that keeps accelerating on a day-per-day basis since, many of the largest web-scale deployments are using Ubuntu. This includes financial, big data, media, and many other workloads and use cases, which rely on the stability and continuity of the underlying operating system to provide the mission-critical service their customers rely on. Extended Security Maintenance (ESM) was introduced for Ubuntu 12.04 LTS as a way to extend the availability of critical and important security patches beyond the nominal End of Life date of Ubuntu 12.04. Organisations use ESM to address security compliance concerns while they manage the upgrade process to newer versions of Ubuntu under full support. The ability to plan application upgrades in a failsafe environment continues to be cited as the main value for adoption of ESM. With the End of Life of Ubuntu 14.04 LTS in April 2019, and to support the planning efforts of developers worldwide, Canonical is announcing the availability of ESM for Ubuntu 14.04.
  • Canonical Announces Ubuntu 14.04 LTS (Trusty Tahr) Extended Security Maintenance
    Canonical announced today that it would extend its commercial Extended Security Maintenance (ESM) offering to the Ubuntu 14.04 LTS (Trusty Tahr) operating system series starting May 2019. Last year on April 28, 2017, when the Ubuntu 12.04 LTS (Precise Pangolin) operating system series reached end of life, Canonical announced a new way for corporate users and enterprises to receive security updates if they wanted to keep their current Ubuntu 12.04 LTS installations and had no plans to upgrade to a newer LTS (Long Term Support) release. The offering was called Extended Security Maintenance (ESM) and had a great success among businesses.

Security: Updates, US Demand for Back Doors, and Microsoft's Collusion with the NSA Keeps Serving Crackers

  • Security updates for Wednesday
  • State Department Still Sucks At Basic Cybersecurity And Senators Want To Know Why
    The senators are hoping the State Department will have answers to a handful of cybersecurity-related questions by October 12th, but given the agency's progress to compliance with a law that's been on the book for two years at this point, I wouldn't expect responses to be delivered in a timelier fashion. The agency's track record on security isn't great and these recent developments only further cement its reputation as a government ripe for exploitation. The agency's asset-tracking program only tracks Windows devices, its employees are routinely careless with their handling of classified info, and, lest we forget, its former boss ran her own email server, rather than use the agency's. Of course, given this long list of security failures, there's a good possibility an off-site server had more baked-in security than the agency's homebrew.
  • EternalBlue Vulnerability Puts Pirated Windows Systems at Malware Risk [Ed: Microsoft's collusion with the NSA (for US-controlled back doors) continues to cost billions... paid by people who foolishly chose or accepted PCs with Windows.]
    A particular vulnerability that has been codenamed EternalBlue is to be blamed for this misfortune. The malware risk especially affects computers which use pirated Windows versions. This gap in security has its traces back in the legacies of US secret service NSA. Even after several years, many systems continue to be vulnerable. For more than three years, US intelligence was using it for performing hidden attacks on all kinds of targets. The agency finally had to leak the vulnerability to Microsoft due to the danger of hacking by a famous hacker group, Shadow Brokers. Microsoft then consequently had to abandon a patch day for the very first time in the company’s history for filling in the gap as quickly as possible.
