  • CrossOver 20 for Chrome OS uses the Linux container to enable Windows app support on Chromebooks

    Over the past several years, Google has slowly turned Chrome OS into a more powerful computing platform, allowing people to use Progressive Web Apps, Android apps, and even Linux apps. While Google is working on its own means of bringing Windows app support to Chrome OS, third-party companies like CodeWeavers have released solutions that Chromebook users can take advantage of today. Today, CodeWeavers released CrossOver 20, bringing Windows app support out of beta for Chrome OS.

  • Google adds WireGuard VPN to Android 12's Linux Kernel 5.4 Tree

    With remote work becoming the norm at many businesses thanks to COVID-19, it’s more important than ever to secure network connections with a virtual private network, or VPN. There are multiple VPN tunneling protocols that services can make use of, but a relatively new implementation called WireGuard has taken the tech world by storm. As we’ve explained before, WireGuard is a next-gen VPN protocol that embraces modern cryptography standards and has a secure, auditable code base. After its inclusion in Linux Kernel 5.6, Google is now adding support for the protocol to Android 12’s Linux Kernel 5.4 tree.

    Google forks each Linux Kernel release to include “patches of interest to the Android community that haven’t been merged onto mainline or Long Term Supported (LTS) kernels.” These kernels are called Android Common Kernels and they form the basis of the Linux kernel release that ships on each and every Android device on the market today. For each Android release, Google supports a handful of Linux kernel releases; for Android 11, that’s currently Linux Kernel versions 4.14 and 4.19, while for Android 12, it’ll be versions 4.19 and 5.4.

  • Android 12 Appears To Support Using WireGuard - Phoronix

    WireGuard has long been available as an app on the Google Play store for those wishing to use this cross-platform, open-source secure VPN tunnel solution on Google's mobile operating system. But for Android 12 it appears there will be a form of official support.

    With WireGuard 1.0 marked by the kernel module being upstreamed in Linux 5.6, it looks like Google is now more comfortable in shipping WireGuard for their Android kernel.

  • It Takes Geological Patience To Change Datacenter Storage

    Moving from an HPC center or a hyperscaler to work on enterprise software has to be a frustrating experience. In the HPC and hyperscaler world, when you need to deal with a problem, it is usually one of scale or performance – or both – and you have to solve the problem now. Like in a year or less, but sometimes you get more time to refine things. Call it 18 months, tops. The new platform – database, storage, network control, compute control, whatever it is – goes into production and months later replaces whatever was going to run out of gas just in time to save the company.

    The enterprise, into which we lump government and academic institutions, by contrast, move at a much slower pace because the risk profile is much higher. If your email or social network or media archive is down for minutes, hours, or even days, no one is going to die. But if an enterprise has an outage and either customer data is compromised or normal business is interrupted, reputation and money are on the line.

    [...]

    The first Quobyte release came in late 2014, a little more than a year after the company’s founding – see how fast these hyperscalers move? – and it was designed from the ground up to be a POSIX-compliant object storage system with file and block overlays when necessary, with triple redundancy of data running on absolutely plain vanilla X86 Linux servers.

Professional animation is not just possible but ideal with free software, this story shares what is possible running PureOS, Librem laptops, and accessories. I have been using free software for 6 years and each year these freedom respecting professional tools I use seem to improve faster than the commercial proprietary pace.

Krita, as an example, released an animation feature that made it the perfect tool for making rough animations. That same year, the software Toonz, that was used by the legendary Studio Ghibli for clean up and coloring purpose, was released as free software under the name of OpenToonz. Nice, with just these two features and tools released, I had everything I needed to do traditional animations again with my Librem based digital studio. Below I will go through the workflow of making a simple hand made 2D animation.

This particular animation was commissioned to me, during the summer, by a young french film production called Baze Production. The goal of this project was to make a cute production identity intro in the same style as Pixar or Illumination Studios, but with hand made animations instead of 3D computer graphics. For that matter, I used 2 Librem laptops and 2 Wacom tablets.

Open source licensing and why we're changing Plausible to the AGPL license

Filed under
GNU
Legal

Plausible Analytics is a software as a service open source web analytics project. With the increase in popularity of Plausible in recent months, we’ve become aware that there are risks associated with permissive open source licenses that corporations that don’t care about open source are happy to take advantage of.

So we’re making a change to our license. This change doesn’t affect anyone subscribing to the Plausible Analytics Cloud and anyone who’s running Plausible Analytics Self-Hosted on their server. Everything stays the same.

The change will affect corporations that want to take our code and use it to create and sell proprietary tools that directly compete with us. Let’s look at the details.

[...]

These corporations use Google Analytics to track their users, have Facebook pixels to target the same users with advertising across the web and so on. Everything we stand against.

Their motives don’t seem to be to make the web more privacy-friendly and reduce the dominance of Google. It seems purely a business opportunity to make money from open source.

  • Cloud Native Application Delivery Using GitOps - The Python Podcast

    The way that applications are being built and delivered has changed dramatically in recent years with the growing trend toward cloud native software. As part of this movement toward the infrastructure and orchestration that powers your project being defined in software, a new approach to operations is gaining prominence. Commonly called GitOps, the main principle is that all of your automation code lives in version control and is executed automatically as changes are merged. In this episode Victor Farcic shares details on how that workflow brings together developers and operations engineers, the challenges that it poses, and how it influences the architecture of your software. This was an interesting look at an emerging pattern in the development and release cycle of modern applications.

  • Graphics in Qt 6.0: QRhi, Qt Quick, Qt Quick 3D

    Last year we had a three part blog series about Qt's new approach to working with 3D graphics APIs and shading languages: part 1, part 2, part 3. For Qt Quick, an early, opt-in preview of the new rendering architecture was shipped in Qt 5.14, with some improvements in Qt 5.15. With the release of Qt 6.0 upcoming, let's see what has happened since Qt 5.15. It will not be possible to cover every detail of the graphics stack improvements for Qt Quick here, let alone dive into the vast amount of Qt Quick 3D features, many of which are new or improved in Qt 6.0. Rather, the aim is just to give an overview of what can be expected from the graphics stack perspective when Qt 6.0 ships later this year.

It is, indeed, just like playing from notes. However, it lets you master your tools and practice your ability to hear and think. In this post, we are going to re-play the classic Multi-Layer Perceptron. Most importantly, we will play the solo called backpropagation, which is, indeed, one of the machine-learning standards. As usual, we are going to show how the math translates into code. In other words, we will take the notes (equations) and play them using bare-bone numpy.

  • PyDev of the Week: William Horton

    This week we welcome William Horton (@hortonhearsafoo) as our PyDev of the Week! William is a Backend Engineer at Compass and has spoken at several local Python conferences. He is a contributor to PyTorch and fastai. Let’s spend some time getting to know William better! Can you tell us a little about yourself (hobbies, education, etc): A little about myself: people might be surprised about my educational background–I didn’t study computer science. I have a bachelors in the social sciences. So by the time I finished undergrad, the most programming I had done was probably doing regressions in Stata to finish my thesis. I decided against grad school, and instead signed up for a coding bootcamp (App Academy) in NYC. The day I’m writing this, September 28, is actually 5 years to the day that I started at App Academy. Since then I’ve worked at a few different startups in NYC, across various industries: first investment banking, then online pharmacy, and now real estate. I’m currently a senior engineer on the AI Services team at Compass, working on machine learning solutions for our real estate agents and consumers. I like to spend my free time on a few different hobbies. I’m a competitive powerlifter, so I like to get into the gym a few times a week (although with the pandemic in NYC I didn’t lift for six months or so). I’ve actually found powerlifting to be a pretty common hobby among software engineers. Every time someone new joined my gym, it seemed like they came from a different startup. I love to play basketball. And I’m passionate about music: I’ve been a singer almost my whole life, and most recently was performing with an a cappella group in NYC. And in the last year I’ve picked up the guitar, after not touching it since I was a teenager, and that has been very fulfilling.

  • Malayalam fonts: Beyond Latin font metrics | Soliloquies

    This year’s annual international conference organized by TeX Users Group — TUG2020 — was held completely online due to the raging pandemic. In TUG2020, I have presented a talk on some important Malayalam typeface design factors and considerations. The idea and its articulation of the talk originated with K.H. Hussain, designer of well-known fonts such as Rachana, Meera, Meera Inimai, TNJoy etc. In a number of discussions that ensued, this idea was developed and later presented at TUG2020. Opening keynote to TUG2020 was delivered by Steve Matteson, about the design of Noto fonts. He mentioned that Noto was originally envisaged to be developed as a single font containing all Unicode scripts; but that was changed due to a couple of reasons: (1) huge size of resulting font and (2) the design of many South/South-East Asian characters do not fit well within its Latin font metrics.

Jérôme is a ReactOS veteran who has been contributing to the project since 2009. He has deep expertise into nearly all parts of ReactOS, ranging from various user-mode components (mostly related to low-level graphics) over their kernel-mode counterparts and down to bare-metal components like the kernel memory manager. During the upcoming months, Jérôme is going to overhaul the Mm (Memory Manager) and Cc (Cache Controller) components of the kernel. Both of them are core parts of the operating system, which are involved in every memory request and file operation. Improving them is expected to have a substantial effect on the overall stability and performance of ReactOS.

Corsair Power Supplies May Soon See Sensor Support Exposed Under Linux

Select high-end Corsair power supplies such as their RMi / HXi / AXi series are able to expose various sensor metrics via USB interface to the system. To date this sensor functionality has only worked under Windows with their proprietary software but now an open-source driver is seeking mainline inclusion for supporting these sensors under Linux. Independent developer Wilken Gottwalt reverse-engineered the micro-controller found on the Corsair RMi/HXi/AXi power supplies and found it to be a proprietary but simple USB HID protocol. The controller exposes temperatures, current, and voltage levels along with other information like power uptime, power used, and power supply fan speed. This protocol on select models can also allow configuring the fan mode and mono/multi-rail voltage handling, and over-current protection.

    YAML Ain't a Markup Language (YAML), and as configuration formats go, it's easy on the eyes. It has an intuitive visual structure, and its logic is pretty simple: indented bullet points inherit properties of parent bullet points. But this apparent simplicity can be deceptive. It's easy (and misleading) to think of YAML as just a list of related values, no more complex than a shopping list. There is a heading and some items beneath it. The items below the heading relate directly to it, right? Well, you can test this theory by writing a little bit of valid YAML.
