  • Use sshuttle to build a poor man’s VPN

    Nowadays, business networks often use a VPN (virtual private network) for secure communications with workers. However, the protocols used can sometimes make performance slow. If you can reach reach a host on the remote network with SSH, you could set up port forwarding. But this can be painful, especially if you need to work with many hosts on that network. Enter sshuttle — which lets you set up a quick and dirty VPN with just SSH access. Read on for more information on how to use it.

    The sshuttle application was designed for exactly the kind of scenario described above. The only requirement on the remote side is that the host must have Python available. This is because sshuttle constructs and runs some Python source code to help transmit data.

    [...]

    Depending on the capabilities of your system and the remote system, you can use sshuttle for an IPv6 based VPN. You can also set up configuration files and integrate it with your system startup if desired. If you want to read even more about sshuttle and how it works, check out the official documentation.

  • Hardening Firefox against Injection Attacks

    Firefox not only renders web pages on the internet but also ships with a variety of built-in pages, commonly referred to as about:pages. Such about: pages provide an interface to reveal internal state of the browser. Most prominently, about:config, which exposes an API to inspect and update preferences and settings which allows Firefox users to tailor their Firefox instance to their specific needs.

    Since such about: pages are also implemented using HTML and JavaScript they are subject to the same security model as regular web pages and therefore not immune against code injection attacks. More figuratively, if an attacker manages to inject code into such an about: page, it potentially allows an attacker to execute the injected script code in the security context of the browser itself, hence allowing the attacker to perform arbitrary actions on the behalf of the user.

    To better protect our users and to add an additional layer of security to Firefox, we rewrote all inline event handlers and moved all inline JavaScript code to packaged files for all 45 about: pages. This allowed us to apply a strong Content Security Policy (CSP) such as ‘default-src chrome:’ which ensures that injected JavaScript code does not execute. Instead JavaScript code only executes when loaded from a packaged resource using the internal chrome: protocol. Not allowing any inline script in any of the about: pages limits the attack surface of arbitrary code execution and hence provides a strong first line of defense against code injection attacks.

  • IPFire on AWS: Update to IPFire 2.23 - Core Update 136

    Today, we have updated IPFire on AWS to IPFire 2.23 - Core Update 136 - the latest official release of IPFire.

    This update includes security fixes for OpenSSL and the Linux kernel, an updated Perl, and of course many other fixes throughout the whole system.

  • Pros and cons of event-driven security

    Great news, everyone! Forrester Research says that 95% of all recorded breaches in 2016 came from only three industries: government, technology, and retail. Everyone else is safe... ish, right?

    Hold on for a moment. Tech? Retail? What kind of industry diversification is this? We are, after all, living in 2019, where every business is a tech business. And all of us are continuously selling something, whether it’s an innovative product or an amazing service.

    So what the report should have said is that 95% of all recorded breaches came from attacks on 95% of all businesses both online and offline. And some of the attackers went for the .gov.

    More on the matter, 43% of attackers target small businesses—and that’s a lot considering that, on average, a hack attempt takes place every 39 seconds.

    To top things off, the average cost of a data breach in 2020 is expected to exceed $150 million. These stats sound a bit more terrifying out of context, but the threat is still very much real. Ouch.

  • Odds and ends, the Linux and gaming Sunday Section

    Almost time to begin another week full of news, before we do let's run over a few interesting happenings recently.

    Let's start with two bits of recent news about Godot Engine, the free and open source game engine. The 3.2 release cycle is going strong, with a second alpha release now available. A massive list of new features and improvements coming to Godot 3.2 can be found here. What's even more exciting though is the Vulkan work coming with Godot Engine 4.0, with another short progress report post up for it. The new visual frame profiler coming certainly looks useful to help developers squeeze out some more performance.

    More AMD news for you, as it has been reported by Wccftech that AMD now command around 30%+ market share of the CPU market. That's some very impressive growth, pushed forward by the Zen microarchitecture from 2017. As seen in the graph below from cpubenchmark.net, this is the highest they've seen it since 2007.

  • SFB Games to bring Tangle Tower to Linux post-launch if there's enough demand

    British indie studio SFB Games, developer of the highly rated Detective Grimoire are working on a new game called Tangle Tower and with a little push they could bring it to Linux.

    Tangle Tower is a fully voiced point and click murder mystery adventure, set in a strange and twisted mansion. You will need to interrogate suspects and solve unique puzzles as you progress. Looks and sounds like a great game. Sadly though it's currently scheduled to release later this month only for Windows and macOS on October 22nd, so no Linux support at launch.

  • Turn-based political simulation game 'Lawgivers' adds Linux support with the latest update

    Today I came across Lawgivers, a turn-based political simulation game which recently added Linux support and it looks like it could be a lot of fun.

    Since it's a political sim, you will be tasked with leading your party into elections. If you manage to get voted in, you will be responsible for approving laws and shaping your country’s destiny.

  • The completely silly fighting game Foreskin Fury is out in Early Access

    After a short delay, you can now jump into Foreskin Fury and have a cock fight. Yes this is a very real game.

    Made in Unreal Engine, the aptly named Stupid Industries said it started off as a joke and they ended up actually learning Blender and Unreal Engine to turn the joke into something a little more real. Here we are, Foreskin Fury was accepted onto Steam and it supports Linux.

  • The currently free indie RTS 'The Fertile Crescent' should now work better at different resolutions

    The Fertile Crescent is an upcoming in-development indie RTS that feels like a retro Age of Empires and it's really quite good. A new update is out (and it's still free) fixing up the UI for different resolutions.

    I think more of you need to try this one, it's a wonderful little RTS game that I honestly can't wait to see expand. Hopefully now more of you actually will be able to try it, as they've made it so the interface properly scales with your resolution. Previously, there were problems if you had anything other than 1080p. Not only that, most of the interface was actually redesigned and it gives you more information.

  • Chiaki, the open source and cross-platform PS4 Remote Play client now supports the PS4 7.0 update

    Sony recently upgraded the system software on the PlayStation 4 which broke compatibility with the open source Remote Play client Chiaki. The developer acted quickly and a new release is up.

    This is the software we tested out recently and came away pretty impressed with it. Allowing you to stream games from a PlayStation 4 to a Linux desktop, seriously handy stuff since Sony don't support it on Linux officially.

My Linux story: I grew up on PC Magazine not candy

Filed under
Linux

In 1998, the movie Titanic was released, mobile phones were just a luxury, and pagers were still in use. This was also the year I got my first computer. I can remember the details as if it were yesterday: Pentium 133MHz and just 16MB of memory. Back in that time (while running nothing less than Windows 95), this was a good machine. I can still hear in my mind the old spinning hard drive noise when I powered that computer on, and see the Windows 95 flag. It never crossed my mind, though (especially as an 8-year-old kid), that I would dedicate every minute of my life to Linux and open source.

Being just a kid, I always asked my mom to buy me every issue of PC Magazine instead of candies. I never skipped a single issue, and all of those dusty old magazines are still there in Costa Rica. It was in these magazines that I discovered the essential technology that changed my life. An issue in the year 2000 talked extensively about Linux and the advantages of free and open-source software. That issue also included a review of one of the most popular Linux distributions back then: Corel Linux. Unfortunately, the disc was not included. Without internet at home, I was out of luck, but that issue still lit a spark within me.

Apple of 2019 is the Linux of 2000

Filed under
GNU
Linux
Mac

Last week the laptop I use for macOS development said that there is an XCode update available. I tried to install it but it said that there is not enough free space available to run the installer. So I deleted a bunch of files and tried again. Still the same complaint. Then I deleted some unused VM images. Those would free a few dozen gigabytes, so it should make things work. I even emptied the trash can to make sure nothing lingered around. But even this did not help, I still got the same complaint.

At this point it was time to get serious and launch the terminal. And, true enough, according to df the disk had only 8 gigabytes of free space even though I had just deleted over 40 gigabytes of files from it (using rm, not the GUI, so things really should have been gone). A lot of googling and poking later I discovered that all the deleted files had gone to "reserved space" on the file system. There was no way to access those files or delete them. According to documentation the operating system would delete those files "on demand as more space is needed". This was not very comforting because the system most definitely was not doing that and you'd think that Apple's own software would get this right.

After a ton more googling I managed to find a chat buried somewhere deep in Reddit which listed the magical indentation that purges reserved space. It consisted of running tmutil from the command line and giving it a bunch of command line arguments that did not seem to make sense or have any correlation to the thing that I wanted to do. But it did work and eventually I got XCode updated.

After my blood pressure dropped to healthier levels I got the strangest feeling of déjà vu. This felt exactly like using Linux in the early 2000s. Things break at random for reasons you can't understand and the only way to fix it is to find terminal commands from discussion forums, type them in and hope for the best. Then it hit me.

Contributor License Agreement and Developer Certificate of Origin references

OSS
Legal

In the last few years I have come across the CLA topic several times. It is and will be a popular topic in automotive the coming years, like in any industry that moves from being an Open Source Producer towards becoming an Open Source Contributor.

In my experience, many organizations take the CLA as a given by looking at the google, microsoft or intels of the world and replicate their model. But more and more organizations are learning about alternatives, even if they do not adopt them.

What I find interesting about discussing the alternatives is that it brings to the discussion the contributor perspective and not just the company one. This enrichs the debate and, in some cases, leads to a more balanced framework between any organization behind a project and the contriibutor base, which benefits both.

Throughout these years I have read a lot about it but I have never written anything. It is one of those topics I do not feel comfortable enough to write about in public probably because I know lots of people more qualified than I am to do so. What I can do is to provide some articles and links that I like or that have been recommended to me in the past.

Linux 5.4-rc3

Filed under
Linux
Things continue to look fairly normal, with rc3 being larger than rc2,
as people are starting to find more regressions, but 5.4 so far
remains on the smaller side of recent releases.

The diffstat looks fairly flat too, although we had a couple of
staging drivers being removed here that show up as spikes. Drivers in
general account for about two thirds of the diff, and it's not just
those staging drivers, it's other small noise all over the place: usb,
drm, iio, rdma..

Outside of drivers, filesystems pop up more than perhaps usual, but
it's again mostly low-grade noise all over: btrfs, cifs, nfs, ocfs,
xfs and some core vfs fixes.

The rest is arch updates (mainly arm64, x86, mips), tooling (mostly
perf tooling updates, but also some selftest fixlets), documentation,
and misc core kernel and mm stuff.

There really isn't anything huge that stands out. You can scan the
appended shortlog for a flavor of the details, it's not too long to
just scroll through.

Reviews

Archman is an Arch Linux-based distribution developed in Turkey. The project's website is available in both Turkish and English, which makes the distribution approachable to non-Turkish audiences. Archman has various releases with different desktop environments and release dates. In this review, I will be reviewing Archman's Xfce 2019-09 release, which is codenamed Lake With Fish.

To begin, I downloaded the 1.6GB ISO and copied it to a flash drive. I rebooted my computer, turned off Secure Boot, and started Archman from the flash drive. The boot process was quick, but I ended up at a graphical login screen instead of a working desktop environment. I pressed the Enter key and I logged in without needing a password.

The live desktop looked very nice. It is an interesting blend of classic and modern. The live desktop has icons for the user's home folder and Trash. There is also a shortcut for Hexchat and the Calamares Archman Installer. The panel at the bottom of the screen holds the application menu, shortcuts for showing the desktop/quickly minimizing all running applications, Firefox, the user's home folder, sections for the currently running applications, switching desktops, a clock, Bluetooth and wireless controls, a battery meter, update notifications, volume control, and a log out/reboot/shutdown shortcut. The panel is 70% the width of the screen and set to automatically hide.

I looked around the live desktop for a little while. I tested to make sure that everything was working okay with my hardware, and once I was certain that all my hardware worked, I moved on to installing Archman.

  • Open Source Hardware Trends, Arm Takes a Different Tack

    The open-source movement that has driven software innovation is now creating a buzz in the microprocessor realm, thanks to the growing popularity of open-source microprocessor instruction set architecture RISC-V. Although the term “open source” conveys sentiments such as research sharing and community building, leading semiconductor IP provider Arm, which supports 95 percent of smartphone embedded processors, is not a fan.

    Synced recently sat down with Rhonda Dirvin, who is Arm’s senior director of Embedded, IoT and Automotive Marketing. Dirvin believes today’s open source hardware landscape is not as simple and straightforward as it may seem: “We’re starting to see some people say free is not free. Because at the end of the day they have to look at what it takes to verify that and what it takes to implement the instruction or architecture. You don’t have the whole ecosystem out there that supports it the way that you do with Arm or some of the other more established vendors.”

  • New Vector to scale open-source alternative to WhatsApp and Slack, where users own their data

    New Vector has announced $8.5 million in funding to scale its open-source, secure communication network, a bid to revolutionise data privacy and ownership in the messaging app space. The investments come from European VCs who specialize in enterprise tech: Notion Capital, Dawn and firstminute capital.

    Necessary for understanding New Vector’s business is to first understand Matrix. Matrix is an open-source project, building a global network for decentralised communication. Users can collaborate securely via end-to-end encryption, and notably, they retain all ownership and control over their data.

  • New Vector raises $8.5 million to develop an open source Slack and WhatsApp

    Tech giants like Facebook, Google, Apple, and Microsoft needn’t be gatekeepers to communication. That’s the idea upon which Matrix, an open standard and decentralized protocol for real-time communication, was formulated. It’s designed to allow users of one service provider to communicate with users of different providers via online chat, voice over IP, and videotelephony, ideally as seamlessly as SMTP (Simple Mail Transfer Protocol) facilitates email exchanges across clients and services.

    Implementing the Matrix protocol at scale requires infrastructure and technical expertise, however — and that’s where startups like New Vector have carved out a niche for themselves. In a little over two years, the startup has helped to grow the Matrix network 400% to 11 million users across 40,000 deployments, including French and U.S. government agencies, Wikipedia parent Wikimedia, KDE, RedHat, and more.

  • After Dallas County's TechShare software failure, the future must be open source

    There has been plenty of coverage of the very expensive failures of TechShare, Dallas County's attempt to create case-tracking software that could be used in any Texas criminal court. Like many battles over operations-level issues, it is easy to miss the forest for the trees.

    One basic principle of good governing was flagrantly violated in this instance: Government shouldn't be involved in a for-profit operation. TechShare's leadership sought profit, rather than to merely recoup costs. I hope members of both parties can agree this is a principle we should consciously adopt. A public discussion will help avoid future misadventures that cost the county $30 million for a hot plate of nothing.

    The term "crony capitalism" gets tossed around a lot, and it sometimes unfairly tarnishes good models of public-private partnerships. Crony capitalism usually means the government gives preference to certain favored private firms without seeking the best price (or quality) for a service or good. That preference is odious because it denies taxpayers the best price. Crony capitalism props up firms that would otherwise fail, using taxpayer money as insurance.

  • AI Researchers' Open-Source Model Explanation Toolkit AllenNLP Interpret

    Although the techniques are generic, AllenNLP Interpret is intended for use in NLP. Inputs to NLP systems are strings of text, usually sentences or whole documents, and the text is parsed into its constituent words or tokens. AllenNLP Interpret includes saliency maps that show each token's contribution to the model prediction; a use case for this might be explaining which words in a sentence caused its sentiment to be classified as positive or negative. The toolkit also includes two adversarial methods that show how changing the tokens in the input could affect the output. The first, HotFlip, replaces the input word that has the highest gradient with other words until the model output changes. The other attack, input reduction, iteratively removes the word with the smallest gradient without changing the output; this results in input texts that are "usually nonsensical but cause high confidence predictions."

  • Open Source Rules the World

    Not too long ago I attended Linux Foundation’s Open Source Summit in San Diego, and this declaration of world dominance (tongue in cheek) was a fairly prominent refrain throughout. From best practices in OS development to emerging technologies to getting started—how to create an open source strategy, sustain it, and the right path to developing an Open Source Program Office (OSPO).

    All open source all the time.

    What became abundantly clear to me through the cacophony of voices representing developers, technologists and enthusiasts is that at the center of all that is open source are three key components critical to ultimate success (however you define it): people, processes, and technology.

    [...]

    The entire tech space is being redesigned by a digital transformation and the emergence of new open source technology platforms. It’s a revolution of sorts, led by groundbreaking innovations in machine learning, open source IoT, cyber security, virtual reality, big data analytics, blockchain and open source development tools. Additionally, there’s technology to help you know what’s in your code and automate the detection and remediation of license compliance and security issues in your DevOps life cycle.

  • Open Source Seed, a Hoax or a Wake-Up Call?

    “Open source” is a trend in various industries. It started to take root in the software industry (Mozilla), followed by biotechnology (CAMBIA) and publishing, where the creative commons concepts have taken root. Several of these trends are based in an opposition against corporate power generated by exclusive rights provided by patents and copyright. Others have a positive goal, i.e. to enhance participation by a much wider population to generate, validate and share information (e.g. Wikipedia).

    The seed sector has a very good story to tell with regard to its contributions to societal goals, but in parts of society, the corporate image and the use of patents create questions, so we could expect that also our sector would be challenged. It is there now. The University of Wisconsin developed an Open Source Seed Initiative several years ago, which was followed in Germany more recently. Access to “freed” plant genetic resources is made conditional to users making them available under the same “open source” conditions – that no IP is vested. The system should thus go “viral” and “force” breeders to join and thus stop protecting their products through IP.

  • Satellite images and open-source programs for mapping during disasters

    A few weeks ago, the states of Assam and Bihar were reeling under floods. Over 200 people were reported dead, with at least 10 million (one crore) of the states’ residents estimated to have been displaced. To save more lives and prevent further infrastructural damage, search and rescue missions during such disasters need to be effective, and more importantly, need to be rapid.

    The answer to this may lie in space.

    Open-source access to satellite images and new technologies to process these images have been a significant breakthrough to help document the true extent of flooding. Getting this information in time is key to plan and conduct evacuation missions, response operations and damage assessments.

    The European Space Agency (ESA)’s Sentinel-1 mission and the web-based Google Earth Engine (GEE) platform are two recent developments that have helped timely capture and analysis of satellite information.

    A research team from the Indian Institute for Human Settlements (IIHS) used this combination (Sentinel and GEE) to come up with an illustrative example of how such mapping can be used in the future to help in rescue missions, through accurate mapping of flood extents.

  • Brief on Behalf of Amicus Curiae Open Source Hardware Association in Curver Luxembourg, SARL v. Home Expressions Inc., No. 18-2214 (Fed. Cir.)

    Curver Luxembourg, SARL v. Home Expressions Inc. is a case of first impression for the Court of Appeals for the Federal Circuit. The question on appeal is whether a design patent’s scope is tied to the article of manufacture disclosed in the patent. In this amicus brief, the Open Source Hardware Association (“OSHWA”) explains the potential effects on open source hardware development, and design practice generally, of untethering design patent protection from the article of manufacture disclosed in the patent. A large percentage of open-source hardware combines both ornamental and functional elements, and industrial design routinely involves applying design concepts from disparate fields in novel ways. To engage in this practice, open-source hardware designers need to know the universe of available source material and its limits. Further, understanding the licensing requirements of open-source hardware begins with understanding how the elements that make up that hardware may or may not be protected by existing law. Accordingly, while many creators of open-source hardware do not seek patent protection for their own creations, an understandable scope of design patent protection is nonetheless essential to their ability to collaborate with other innovators and innovate lawfully. The brief argues that the District Court in the case—and every district court that has considered the issue—correctly anchored the patented design to the article of manufacture when construing the patent. The brief explains that anchoring the patented design to the disclosed article of manufacture is the best approach, for several reasons. Connecting the patented design to the disclosed article of manufacture calibrates the scope of design patent protection to the patentee’s contribution over the prior art. It avoids encumbering the novel and nonobvious application of prior designs to new articles of manufacture, a fundamental and inventive practice of industrial design. It aligns the scope of design patent protection with its purpose: encouraging the inventive application of a design to an article of manufacture. This balances protection for innovative designs with later innovators’ interest in developing future designs. Finally, anchoring the patented design to the disclosed article of manufacture helps fulfill design patent law’s notice function by clarifying the scope of protection.

  • Gallium3D's Mesa State Tracker Sees "Mega Cleanup" For NIR In Mesa 19.3

    AMD developer Marek Olšák has landed a "mega cleanup" to the Gallium3D Mesa state tracker code around its NIR intermediate representation handling. As part of getting the NIR support in good enough shape for default usage by the RadeonSI driver, Marek has been working on a number of clean-ups involving the common Gallium / Mesa state tracker code for NIR.

  • AMDGPU DC Looks To Have PSR Squared Away - Power-Savings For Newer AMD Laptops

    It looks like as soon as Linux 5.5 is where the AMDGPU kernel driver could be ready with Panel Self Refresh (PSR) support for enabling this power-savings feature on newer AMD laptops. While Intel's Linux driver stack has been supporting Panel Self Refresh for years, the AMD support in their open-source Linux driver code has been a long time coming. We've seen them working towards the support since Raven Ridge and now it appears the groundwork has been laid and they are ready to flip it on within the Display Core "DC" code.

    Computing with data whose form is not the most convenient way to be manipulated, like is often the case in unstructured binary data, requires performing a preliminary step that transforms the data into a more convenient representation, usually featuring a higher level of abstraction. This step is known in computer jargon as unmarshalling, when the data is fetch from some storage or transmission media or, more generally, decoding. Once the computation has been performed, the result should be transformed back to the low-level representation to be stored or transmitted. This is performed in a closing step known as marshalling or, more generally, encoding. Consider the following C program whose purpose is to read a 32-bit signed integer from a byte-oriented storage media at a given offset, multiply it by two, and store the result at the same offset.

  • Android NDK r21 moves to beta

    Android announced that NDK r21 is now in beta. Android NDK is a toolset for implementing parts of an app in native code. The release — which is the first long term support release — includes improved defaults for better security and performance. One of the key features in the release is an update to GNU Make to version 4.2, which provides a number of bug fixes, and enables ‘–output-sync’ to avoid interleaving output with error messages, the team explained. This is enabled by default with ndk-build. Additionally, GDB, the GNU project debugger, has been updated to version 8.3, which includes fixes for debugging modern Intel CPUs.

  • What is the history behind C Programming and Unix?

    If you think C programming and Unix are unrelated, then you are making a big mistake. Back in the 1970s and 1980s, if the Unix engineers at Bell Labs had decided to use another programming language instead of C to develop a new version of Unix, then we would be talking about that language today. The relationship between the two is simple; Unix is the first operating system that is implemented with a high-level C programming language, got its fame and power from Unix. Of course, our statement about C being a high-level programming language is not true in today’s world. This article is an excerpt from the book Extreme C by Kamran Amini. Kamran teaches you to use C’s power. Apply object-oriented design principles to your procedural C code. You will gain new insight into algorithm design, functions, and structures. You’ll also understand how C works with UNIX, how to implement OO principles in C, and what multiprocessing is.

  • Mirantis Partners With OpenStack Foundation to Support Upgraded COA Exam

    “With the OpenStack market forecasted to grow to $7.7 billion by 2022 according to 451 research, the demand for Certified OpenStack Administrators is clearly strong and set to continue growing for many years to come,” said Mark Collier, COO of the OpenStack Foundation. “We are excited to collaborate with Mirantis, who has stepped up to provide the resources needed to manage the COA, including the administration of the vendor-neutral OpenStack certification exam.”

  • How to use containers with an eye on security

    Containers are all the rage. With good reason. With containers, your company’s apps and service deployments become considerably more agile, more reliable, and even more secure. This is true for software development companies (who develop apps and services for other businesses), as well as companies looking to roll out web-based and mobile applications with an unheard of speed and reliability. But with any new technology, comes hurdles. One of the biggest hurdles for any business is security. Data breaches have become rampant and it’s on the shoulders of every company to do everything in their power to make sure they are rolling out technology that is as secure as possible. This idea should certainly be applied to containers. But what can you do to use containers security? Fortunately, there are a few steps that you can take from the very beginning.

  • Pensando Systems Exits Stealth Mode With Plans To Take On Amazon AWS

    While normally we don't cover hardware start-ups on Phoronix, Pensando Systems has just exited stealth and given their focus will be heavily involved with Linux and in fact already have their first kernel driver mainlined. After announcing a $145 million (USD) Series-C round, Pensando Systems exited "stealth" and revealed the first details of what they are trying to achieve with this company led by many ex-Cisco staff. [...] Pensando has been on our radar since as I wrote about last month when they were just a stealth networking startup they already upstreamed their first Linux kernel driver. In the Linux 5.4 kernel is a Pensando "Ionic" driver for a family of network adapters. In this week's press release, Pensando didn't specifically call out Ionic but presumably is the backbone to their hardware. Now that they are beginning to talk about their ambitions, hopefully we see more Linux kernel patches from them soon.
