Ubuntu Web Remix 20.04.3 Released with /e/ on WayDroid and Linux Kernel 5.11

Filed under
Linux
News
Ubuntu

Remember Ubuntu Web? It was first announced last year in November as an alternative to Chrome OS or Chromium OS. It’s an unofficial Ubuntu flavor created by Rudra Saraswat, the maintainer of Ubuntu Unity, offering Web Apps, Android apps, and support for apps from the de-Googled /e/ Foundation.

While it has an emphasis on Web Apps, Ubuntu Web Remix looks and feel like a real GNU/Linux distribution that you can easily put on your desktop or laptop computer. It features the GNOME desktop environment by default, but with a minimal set of native Linux apps pre-installed.

You Can Use Raspberry Pi 400 As a PC Keyboard and Mouse Combo

Filed under
Hardware

If you’re a fan of Pimoroni, you’re probably familiar with its software lead Phil Howard (aka Gadgetoid) and his developments in the Raspberry Pi community. Today we’re sharing an awesome project he put together using our favorite keyboard PC, the Raspberry Pi 400.

Using the right cable and a bit of code, the Raspberry Pi 400 can function as a regular, USB HID keyboard. The best Raspberry Pi projects are easy to recreate and the only accessory you need to pull this project off is a USB Type-C to USB Type-A cable.

  • DearPyGui 1.0.0 user interface Toolkit Released - itsfoss.net

    Published edition Dear PyGui 1.0.0 (the DPG), a cross-platform toolkit for GUI development in Python. The most important feature of the project is the use of multithreading and outsourcing of operations to the GPU to speed up rendering. The key goal of shaping the 1.0.0 release is to stabilize the API. Compatibility-breaking changes will now be proposed in a separate “experimental” module.

    To ensure high performance, the bulk of the DearPyGui code is written in C ++ using the Dear ImGui library , designed for creating graphical applications in C ++ and offering a fundamentally different operating model. The Dear PyGui source code is licensed under the MIT license. Declared support for Linux, Windows 10 and macOS platforms.

  • Software testing - a 32-year-old message

    And then, after having tested hundreds of Linux distributions, thousands of applications, every release of Windows since 3.11, and then some, I can definitely say that the slow, steady erosion of professional testing in the software world is noticeable. And by that mean, in those scenarios it actually existed, because in some domains, it's never been there, and it shows. If anything, the longer I keep my hands on this or that application or program, the more I'm convinced that the new, casual approach to quality is simply not working. There will be a moment of reckoning.

  • Issue #373 - Robotic tickles

    We thought we’d lead with the weirdest Raspberry Pi-powered thing, purely because we couldn’t resist the bizarre visual. These robotic hands move according to actions taken on social media. And they’re creepy. We like creepy.

  • ODROID-H2+ SBC discontinued due to supply shortage - CNX Software

    Hardkernel has just discontinued ODROID-H2+ single board computer based on the Intel Celeron J4115 Gemini Lake Refresh processor, which followed ODROID-H2 SBC itself being discontinued shortly after Intel decided to phase out Intel J4105 and other Gemini Lake processors.

    The reason given is the “uncertain situation of main component supply”, which could mean Celeron J4115 processor is hard to get (or expensive), or the Realtek RTL8125B chipset provides 2.5GbE networking. That means Hardkernel does not offer any x86 SBC at this time. That’s a shame before ODROID-H2+ was a well-supported SBC running Linux or Windows, and great value for money at $119, especially for people interested in the two 2.5 Gbps Ethernet ports found on the board (and upgradeable to six), not to mention support for SO-DIMM memory and M.2 NVMe SSD.

  • Debian blocks VPN and Tor users from reading its Wiki. – BaronHK's Rants

    I understand that they don’t want VPN and Tor users messing up their Wiki anonymously, where it would be difficult to ban any one vandal, but to block people from even _reading it_ unless they unmask themselves is a bit heavy-handed.

    On Wikipedia, they block Tor and VPN users from editing, but you can read it all you want, and you can view the page’s source code if you are on a VPN. This is the right thing to do.

    I’m not sure why Debian is requiring us to de-anonymize ourselves just to read their Wiki. I wish that they would stop doing this.

The new revision of digiKam Recipes features detailed information on how to move digiKam library and databases from one machine to another, how to access digiKam remotely from any machine, and how to import photos from an iOS device. The book now uses the Barlow font for better legibility along with a slightly improved layout.

  • October 2021 Web Server Survey [Ed: Microsoft became so irrelevant in Web servers that it is not even mentioned anymore and most tables don't even list Microsoft (it's miniscule, outside view)]

    In the October 2021 survey we received responses from 1,179,448,021 sites across 265,426,928 unique domains and 11,388,826 web-facing computers. This reflects a loss of 8.59 million sites, but a gain of 1.07 million domains and 20,800 computers.

    The number of unique domains powered by the nginx web server grew by 789,000 this month, which has increased its total to 79.5 million domains and its leading market share to 29.9%. Conversely, Apache lost 753,000 domains and saw its second-place share fall to 24.7%. Meanwhile, Cloudflare gained 746,000 domains – almost as many as nginx – but it stays in fourth place with an 8.15% share while OpenResty's shrank slightly to 14.5%.

    Cloudflare also made strong progress amongst the top million websites, where it increased its share by 0.24 percentage points to 18.2%. nginx is in second place with a 22.5% (+0.12pp) share but has closed the gap on Apache which still leads with 24.0% after losing 0.21pp.

    Apache also continues to lead in terms of active sites, where it has a total of 48.0 million. However, it was the only major vendor to suffer a drop in this metric, with a loss of 277,000 active sites reducing its share down to 23.9% (-0.29pp). In terms of all sites, nginx lost the most (-9.99 million) but remains far in the lead with a total of 412 million.

  • Security Risks of Client-Side Scanning

    Even before Apple made their announcement, law enforcement shifted their battle for back doors to client-side scanning. The idea is that they wouldn’t touch the cryptography, but instead eavesdrop on communications and systems before encryption or after decryption. It’s not a cryptographic back door, but it still a back door — and brings with it all the insecurities of a back door.

    I’m part of a group of cryptographers that has just published a paper discussing the security risks of such a system. (It’s substantially the same group that wrote a similar paper about key escrow in 1997, and other “exceptional access” proposals in 2015. We seem to have to do this every decade or so.) In our paper, we examine both the efficacy of such a system and its potential security failures, and conclude that it’s a really bad idea.

Kernel: Paul E. Mc Kenney and New Stuff in Linux

Filed under
Linux
  • Paul E. Mc Kenney: TL;DR: Memory-Model Recommendations for Rusting the Linux Kernel

    These recommendations assume that the initial Linux-kernel targets for Rust developers are device drivers that do not have unusual performance and scalability requirements, meaning that wrappering of small C-language functions is tolerable. (Please note that most device drivers fit into this category.) It also assumes that the main goal is to reduce memory-safety bugs, although other bugs might be addressed as well. Or, Murphy being Murphy, created as well. But that is a risk in all software development, not just Rust in the Linux kernel.

    Those interested in getting Rust into Linux-kernel device drivers sooner rather than later should look at the short-term recommendations, while those interested in extending Rust's (and, for that matter, C's) concurrency capabilities might be more interested in the long-term recommendations.

  • Cluster Scheduler Support Queued Ahead Of Linux 5.16 - Phoronix

    Cluster scheduler support has been queued up for landing in the Linux 5.16 kernel for AArch64 and x86_64 systems for improving the CPU scheduler behavior for systems that have clusters of CPU cores.

    The cluster scheduler support in this context is about enhancing the Linux kernel's scheduler for systems where sets of CPU cores share an L2 cache or other mid-level caches/resources.

    This cluster scheduler work stems from work by HiSilicon and Huawei aiming to improve the Linux performance for the Kunpeng 920 server chip. That HiSilicon SoC has six or eight clusters per NUMA node with four CPU cores per cluster and a shared L3 cache. With the cluster scheduler patches they were able to enhance the overall performance of the system and also improve the efficiency.

  • Uh oh, looks like Despot's Game: Dystopian Army Builder is going to suck all my time away | GamingOnLinux

    Despot's Game: Dystopian Army Builder is a brand new release from Konfa Games and tinybuild that sees you command a bunch of naked people and send them through a strange post-apocalyptic labyrinth. Note: personal purchase.

    Like it Loop Hero, you have no direct control during combat you just watch it play out and hope for the best. Here though you're running through some kind of maze-like dungeon full of strange machines, with multiple people you need to look after. They'll likely die a lot though, don't get too attached, you can buy more naked people. Eventually you might come across the nefarious d’Spot who runs the show and perhaps destroy them to earn your freedom.

    It blends together quite a few different genres and it feels totally unique. The structure is a bit like The Binding of Isaac with you going from room to room, it's also a strategy game with you buying people and equipping them with various weapons you buy from shops spread throughout the maze and then there's the fusion of auto battling so you can sit back and watch the mess unfold.

    Simon Ser has been hard at work on expanding his soju and gamja projects for the purpose of creating a new core sourcehut product: chat.sr.ht. We’re rolling this out in a private beta at first, to seek a fuller understanding of the system’s performance characteristics, to make sure everything is well-tested and reliable, and to make plans for scaling, maintenance, and general availability. In short, chat.sr.ht is a hosted IRC bouncer which is being made available to all paid sr.ht users, and a kind of webchat gateway which will be offered to unpaid and anonymous users. I’m pretty excited about it, and looking forward to posting a more detailed announcement in a couple of weeks. In other sourcehut news, work on GraphQL continues, with paste.sr.ht landing and todo.sr.ht’s writable API in progress.

    Our programming langauge project grew some interesting features this month as well, the most notable of which is probably reflection. I wrote an earlier blog post which goes over this in some detail. There’s also ongoing work to develop the standard library’s time and date support, riscv64 support is essentially done, and we’ve overhauled the grammar for switch and match statements to reduce a level of indentation for typical code. In the coming weeks, I hope to see date/time support and reflection fleshed out much more, and to see some more development on the self-hosted compiler.

    Well, I got married in the very same month 18 years ago. The best part is, I choose the day 11 to get married. I have never missed my wedding anniversary, thanks to all the TV news channel.

  • My Favorite Warnings: uninitialized | Tom Wyant [blogs.perl.org]

    This warning was touched on in A Belated Introduction, but I thought it deserved its own entry.

    When a Perl scalar comes into being, be it an actual scalar variable or an array or hash entry, its value is undef. Now, the results of operating on an undef value are perfectly well-defined: in a nuneric context it is 0, in a string context it is '', and in a Boolean context it is false.

    The thing is, if you actually operate on such a value, did you mean to do it, or did you forget to initialize something, or initialize the wrong thing, or operate on the wrong thing? Because of the latter possibilities Perl will warn about such operations if the uninitialized warning is enabled.

  • Google adds VM support to Anthos, admits not everyone is ready for containerised everything [Ed: Kubernetes becoming increasingly just an openwashing shim for proprietary software with back doors]

    Google has added support for workloads running in virtual machines to its Anthos hybrid Kubernetes platform.

    "While we have seen many customers make the leap to containerization, some are not quite ready to move completely off of virtual machines," wrote Google Application Modernization Platform vice-presidents Jeff Reed and Chen Goldberg.

    "They want a unified development platform where developers can build, modify, and deploy applications residing in both containers and VMs in a common, shared environment," the pair added.

  • The Dell Inspiron 15 3501 supports Linux

    With the Inspiron 15 3501, Dell has a 15.6-inch office laptop in its lineup with its technology housed in a slim, matte-black plastic case. The chassis lacks stability: The lid and the base unit in particular can be twisted a bit too much. The matte display (Full HD, IPS) offers stable viewing angles, good contrast, and decent color reproduction. However, the brightness and color-space coverage are too low.

    The built-in combination of the Core i7-1165G7 processor, 16 GB of RAM (dual-channel mode), and a 512 GB NVMe SSD (M.2 2230) equips the laptop for office and Internet applications. If the storage space isn't enough, an additional 2.5-inch storage drive can be installed. You can also replace or expand the RAM.

You find your code in the headlines for a different and unpleasant reason: open source dependency management.

  • Printed Piano Mechanism Sure Is Grand | Hackaday

    Do you know how a piano works? Sure, you press a key and a hammer strikes a string, but what are the finer points of this operation? The intricacy of the ingenious mechanism is laid bare in [Mechanistic]’s 3D-printed scale model of a small section of the grand piano keyboard. The ‘grand’ distinction here is piano length-agnostic and simply refers to any non-upright. Those operate the same way, but are laid out differently in order to save space.

  • FPGA Boards Add VGA And HMDI Interfaces To The Original Game Boy | Hackaday

    The classic Game Boy remains a firm favorite in the realm of retrocomputing. Revolutionary as it was at the time, by today’s standards its display is rather primitive, with no backlight and a usable area measuring only 47 mm x 44 mm. [Martoni] figured out a way to solve this, by developing GbVGA and GbHdmi, two projects that enable the Game Boy to connect to an external monitor. This way, you can play Super Mario Land without straining your eyes, and we can also image potential uses for those who stream their gameplay online.

  • Why digital transformation demands a change in leadership mindset

    Recently a key retail executive forecast that their industry will change more in the next five years than it has in the past fifty. Another executive believes society will change more in the next fifty years than it has in the last three hundred. A recent headline declared that, “We are approaching the fastest, deepest, most consequential technological disruption in history”, and Ray Kurzweil, Google’s Director of Engineering and co-Founder of Singularity University, has said that there will be fourteen internet size revolutions in the next decade. Whichever way you look at it, things are shifting… fast.

    When you speak with the visionaries and entrepreneurs actually building the solutions of tomorrow, from on-demand retail to vertical farms, and ask how far into this new era we are, almost universally the reply is: “only one percent”. Imagine then, where we will be ten years from now? How about 50?

    Major industries, from medicine to energy to travel to entertainment, are radically transforming, putting pressure on others such as manufacturing, construction, transportation, finance, education…frankly, all of it. What an extraordinary opportunity this presents.

  • DevSecOps lessons learned during a pandemic | The Enterprisers Project

    As we’ve seen over the past year and a half, the pandemic has accelerated digital transformation and forever changed workplace culture. Increased reliance on digital tools has elevated the value of DevSecOps, as enterprises of all sizes and across all industries realize the importance of automating and integrating security at every phase of the software development lifecycle – from initial design through integration, testing, deployment, and product delivery.

    My engineering team was no exception to this shift – we had to quickly prepare to build a new Virtana SaaS platform and deliver several new modules, all while working remotely.

    Here I’ll share some observations, pain points, and lessons learned to help others intelligently embrace DevSecOps best practices within their teams.

  • White House ransomware summit calls for virtual asset crackdown, without mentioning cryptocurrency [Ed: They need to crack down on Microsoft Windows, instead; they use their NSA back doors as a ruse to protect big banks. Microsoft has infiltrated think tanks about ransomware, so now instead of tackling the security breaches themselves (which can lead to sabotage or worse) they treat it like a financial transaction issue.]

    The 30-nation gabfest convened under the auspices of the US National Security Council’s Counter-Ransomware Initiative has ended with agreement that increased regulation of virtual assets is required to curb the digital coins' allure to criminals.

    A joint statement issued after the event's conclusion opens with anodyne observations about the need for good infosec, international collaboration, and the benefits of private sector engagement.

    The first mention of concrete action comes in a section of the statement entitled "Countering Illicit Finance" – and while the document never mentions cryptocurrencies, it's plain they're a target.

    "Taking action to disrupt the ransomware business model requires concerted efforts to address illicit finance risks posed by all value transfer systems, including virtual assets, the primary instrument criminals use for ransomware payments and subsequent money laundering."

  • Thingiverse suffers breach of 228,000 email addresses • The Register

    Thingiverse, a site that hosts free-to-use 3D printer designs, has suffered a data breach – and at least 228,000 unlucky users' email addresses have been circulating on black-hat crime forums.

    News of the breach came from Have I Been Pwned (HIBP), whose maintainer Troy Hunt uploaded the 228,000 breached email addresses to the site after being tipped off to their circulation on the forums.

    Hunt claimed on Twitter that in excess of two million addresses were in the breach. He qualified that by saying the majority were email addresses that appeared to be generated by Thingiverse itself, judging from their format: webdev+$username@makerbot[.]com.

    HIBP's maintainer also claimed that some of the data included poorly encrypted passwords: one he highlighted was an unsalted SHA-1 hash which resolved to the password "test123".

  • Thingiverse Data Leaked — Check Your Passwords | Hackaday

    Every week seems to bring another set of high-profile data leaks, and this time it’s the turn of a service that should be of concern to many in our community. A database backup from the popular 3D model sharing website Thingiverse has leaked online, containing 228,000 email addresses, full names, addresses, and passwords stored as unsalted SHA-1 or bcrypt hashes. If you have an account with Thingiverse it is probably worth your while to head over to Have I Been Pwned to search on your email address, and just to be sure you should also change your password on the site. Our informal testing suggests that not all accounts appear to be contained in the leak, which appears to relate to comments left on the site.

  • New PureBoot Feature: Scanning Root for Tampering – Purism

    With the latest PureBoot R19 pre-release we have added a number of new changes including improved GUI workflows and new security features and published a ROM image so the wider community can test it before it turns into the next stable release. To test it, existing PureBoot users can download the R19-pre1 .rom file that corresponds to their Librem computer and flash it like any other PureBoot release.

    In this post I want to highlight a new experimental security feature we added in this release that will extend the tamper detection PureBoot already does with the boot firmware and the /boot directory into the main root file system. This will allow you to detect attacks that modify system binaries (like /bin/bash) with backdoored versions. I also want to give some background on this feature and my thought process behind it so people understand where I’m coming from and why I made the design decisions I did.

3 ways to manage RPG character sheets with open source

OSS

It's that time of year again for gamers everywhere.

Tomorrow is Free RPG Day, a day when publishers across the tabletop role-playing game industry release games for players both new and experienced, and they're all completely free. Although Free RPG Day was canceled in 2020, it's back this year as a live event with some virtual support by way of free RPG sampler downloads from Dungeon Crawl Classics and Paizo. And if the event's virtual offerings aren't enough, you might check out my list of open source tabletop RPGs.

Over the past two years, like most people, I've been playing my tabletop games online. I use open source video conferencing and some shared mapping software. Don't get me wrong: I love my pen and paper for analog games. To this day, I rarely leave home without my 2E5 quad book so I can sketch out dungeon maps on the go. But I find my computer desk gets pretty cluttered between RPG sourcebooks, splat books, random tables, dice tower, dice, and character sheets. To clear some space, I've recently adopted a digital system for my character sheets, for both my player characters and non-player characters when I DM.

  • Security Risks of Client-Side Scanning

    Even before Apple made their announcement, law enforcement shifted their battle for back doors to client-side scanning. The idea is that they wouldn’t touch the cryptography, but instead eavesdrop on communications and systems before encryption or after decryption. It’s not a cryptographic back door, but it still a back door — and brings with it all the insecurities of a back door. I’m part of a group of cryptographers that has just published a paper discussing the security risks of such a system. (It’s substantially the same group that wrote a similar paper about key escrow in 1997, and other “exceptional access” proposals in 2015. We seem to have to do this every decade or so.) In our paper, we examine both the efficacy of such a system and its potential security failures, and conclude that it’s a really bad idea.

Kernel: Paul E. Mc Kenney and New Stuff in Linux

  • Paul E. Mc Kenney: TL;DR: Memory-Model Recommendations for Rusting the Linux Kernel

    These recommendations assume that the initial Linux-kernel targets for Rust developers are device drivers that do not have unusual performance and scalability requirements, meaning that wrappering of small C-language functions is tolerable. (Please note that most device drivers fit into this category.) It also assumes that the main goal is to reduce memory-safety bugs, although other bugs might be addressed as well. Or, Murphy being Murphy, created as well. But that is a risk in all software development, not just Rust in the Linux kernel. Those interested in getting Rust into Linux-kernel device drivers sooner rather than later should look at the short-term recommendations, while those interested in extending Rust's (and, for that matter, C's) concurrency capabilities might be more interested in the long-term recommendations.

  • Cluster Scheduler Support Queued Ahead Of Linux 5.16 - Phoronix

    Cluster scheduler support has been queued up for landing in the Linux 5.16 kernel for AArch64 and x86_64 systems for improving the CPU scheduler behavior for systems that have clusters of CPU cores. The cluster scheduler support in this context is about enhancing the Linux kernel's scheduler for systems where sets of CPU cores share an L2 cache or other mid-level caches/resources. This cluster scheduler work stems from work by HiSilicon and Huawei aiming to improve the Linux performance for the Kunpeng 920 server chip. That HiSilicon SoC has six or eight clusters per NUMA node with four CPU cores per cluster and a shared L3 cache. With the cluster scheduler patches they were able to enhance the overall performance of the system and also improve the efficiency.
