↺ Accessing and recovering data with a live Linux distribution


But it’s also useful when trying to access and recover data from a failing drive. In many cases, hard drive failure and data corruption only affects a specific portion of the drive. While this renders data in that section inaccessible and, in many cases, unrecoverable, any data that is stored outside of the affected might remain intact. If your system files have become corrupted, for example, there’s a good chance that your personal files, which are hosted in a different sector on the drive, are still recoverable.


To begin the process and find out, simply install Ubuntu onto a USB flash drive, boot your system and, when prompted, click on “Try Ubuntu.” By clicking this option instead of installing it, you’ll effectively launch a live instance of Ubuntu. Many other Linux distros support this feature in some form or another, but the method for accessing the live instance will likely vary depending on the exact distro you’re using.


If you’re an advanced user, you’ll be able to locate the failed or corrupted hard drive in question once you’ve launched Ubuntu into your system’s RAM. From here, it’s just a matter of mounting the device within Linux and copying that data to another USB drive. For best results, try to avoid using the same drive that contains your Linux distro.


From here, it’s just a matter of copying your data back onto a fully functional machine. While you might be missing some of your data, including whatever was stored in the failed or corrupted sectors, the majority of your information should still be available.


Kernel Space


↺ Linux gods at last turn their gaze to Pi 400: Computer-in-a-keyboard receives mainline kernel support with v5.14 • The Register


Raspberry Pi fans have reasons for cheer this week as support for the Pi 400 showed up in the queue for version 5.14 of the Linux kernel, and hosting outfit Mythic Beasts added overclocked Pi 4s to its Raspberry Pi cloud.


[...]


Software options look set to increase with the arrival of mainline kernel support in Linux 5.14 with the addition of the Pi 400 into DeviceTree (as reported by Phoronix) in the “for-next” branch.


It’s not clear why this has taken quite so long, since the device is very close to the Raspberry Pi 4. No kernel driver tweaks seem to be on the cards, just DTS changes for the higher clock speed, updated Wi-Fi chip, power-off via GPIO, and the dropping of the activity LED.


The latter we noted in our review, where the power LED originally did double-duty for activity and looked downright odd. “It seemed like a good idea at the time,” Pi supremo Eben Upton told us, but the notification was dispensed with in launch models.


↺ Beatriz Martins de Carvalho: Outreachy – Introduction


I am Beatriz Carvalho, brazilian, living in Fundão, Portugal. I am graduated in computer engineering at Unipampa in Brazil. I work mostly with C, Python and I am learning JavaScript, CSS, among other things to create this site… I like Harry Potter, Lord of the Rings, One Piece, The Witcher… I also like to drink wine and some cocktails and last but not least: I love cats, I have two: Ophélia and Cisco.


I’ve just been selected as an Outreachy intern for Linux Kernel working with my mentors Melissa Wen and Daniel Vetter on the project “Improvements to DRI-devel (aka kernel GPU subsystem)”.


As an Outreachy intern, my first step is to say out loud for everyone to see my core values, Outreachy organizers make available a list with some values, and going through the list made me realize some things I value the most in life as an individual and once I started to work in the Linux Kernel these values caught my attention…


↺ Brendan Gregg: USENIX LISA2021 BPF Internals (eBPF)

↺ Keep track of your IRC chats with ZNC | Opensource.com


For a bit more than a year, I’ve been wondering if it is possible to bolt the open source Matrix communications network to Internet Relay Chat (IRC) in such a way that I can still use my ZNC IRC bouncer without an extra proliferation of nicknames. The answer, is amusingly, yes. But first, some background.


What’s IRC?


IRC has been around since August 1988, and it’s been a staple of real-time communications ever since. It’s also one of the early open source projects, as the code for the original IRC server was eventually shared. Over the years, it’s been quite useful for meeting many developers’ real-time communication needs, although not without its own share of drama. However, it has been resilient and is still widely used despite newer options.

↺ Linux apps on Chrome OS in 2021: A complete guide


Chrome OS is incredibly powerful and versatile, running on a variety of hardware and can also run a variety of apps. In addition to running Android apps from the Play Store, it’s also possible to run full Linux apps. For many users, the basic Chromebook functionality is just fine. However, if you find yourself wanting an app or service your Chromebook doesn’t offer out of the box, Linux apps may be for you.


What exactly can you accomplish running Linux apps? Chrome OS by default is a cloud computing platform, which leaves out some desktop-class apps you might see on a Mac or PC. For instance, if you need to run Photoshop natively, that’s not possible on your Chromebook. Video editing is also quite difficult by default on Chrome OS. Both of these problems are addressed by Linux apps.


In addition, if you’re a developer, you undoubtedly need Linux for coding tools. While not all Chromebooks support Linux apps (there are some baseline system requirements), most modern Chromebooks will have the option available. In this guide we walk through precisely how to enable and install Linux apps on your Chromebook, and run down the best Linux apps available on Chrome OS.


↺ Squid proxy configuration tutorial on Linux

This is a great way for networks to reduce bandwidth consumption and provide snappier response times for web browsing.


In this guide, we’ll go over the step by step instructions to download, install, and configure Squid proxy on a Linux system. Follow along with us to get it setup on your own system, which can either provide caching just for yourself or all the way up to an entire organization of computers.


↺ Build a static website with Eleventy | Opensource.com


A static site generator is a tool that generates a full, static HTML website based on raw data and a set of templates. It automates the task of coding individual HTML pages and gets those pages ready to serve to users. Because the HTML pages are prebuilt, they load very quickly in users’ browsers.


Static sites work particularly well for documentation, too, because static sites are easy to scale, and they’re an easy way to generate, maintain, and deploy your project’s documentation. For these reasons, organizations often use them to document application programming interfaces (APIs), database schemas, and other information. Documentation is an important part of software development, design, and other aspects of tech. All codebases require some form of documentation, with options ranging from a simple README to full documentation.

↺ How to Create Hard Disk partitions in ubuntu


Storage devices play a critical role in the working of any system. Different operating systems use various types of file structures to store data. So generally we use GPT or MBL file storage styles for that. With the help of these two we can create partitions in a storage device. Also , We can split large memory sized devices into smaller sub-segments called partitions. Partitioning enables us to split our storage drive into multiple parts. Where each part acts as a seperate single storage drive. Apart from that we can use these partitions to install multiple operating systems in the same machine. Here we will learn to create partition in linux.

You know the drill (get it?) with such a game if you’ve played any building sim. You run around and mine for resources, construct buildings, set up some automation and continually expand until the whole world around you is a well-oiled machine. It’s nowhere near the greatness of Factorio and it’s early days for Boppio but it’s still quite promising.


↺ Kalypso Media to reduce pricing on their games as a result of doing well | GamingOnLinux


Kalypso Media have announced something quite lovely. Since they’re doing so well, they’ve decided that going forward they will be charging less for new and existing games.


As a result of the COVID-19 pandemic, along with a shift to digital games instead of boxes copies and sales of their developed and published games doing so well they’ve now set a price-point for all future new PC releases at €39.99 / $39.99 / £34.99.


“We have been able to increase our digital sales and, above all, margins in recent months, while physical sales in traditional retail have slumped due to the COVID-19 situation. Currently, we do not expect this trend to reverse even after the pandemic. Most of our fans buy or stream games, primarily, digitally, so it is very likely that sales of physical products will continue to decline, saving us costs in manufacturing, logistics and distribution,” said Simon Hellwig, CEO of Kalypso.

↺ KDE Plasma 5.22.1, Bugfix Release for June


Today KDE releases a bugfix update to KDE Plasma 5, versioned 5.22.1.


Plasma 5.22 was released in June 2021 with many feature refinements and new modules to complete the desktop experience.


This release adds a week’s worth of new translations and fixes from KDE’s contributors. The bugfixes are typically small but important and include..


↺ Akademy 2021 at Home


Once again I plan to be at Akademy. I almost silently attended last year edition. OK… I had a talk there but didn’t blog. I even didn’t post my traditional sketchnotes post. I plan to do better this year.


I’ll try to sketchnote again, we’ll see how that works out. Oddly enough, I might do the 2020 post after the 2021 one.


↺ KDE’s Nate Graham: Bug triaging is the foundation of quality and we need more of it


Bug triaging is a largely invisible and often thankless task. But it’s the foundation of quality in our software offerings. Every day, our users file between 30 and 50 bug reports on https://bugs.kde.org, and often up to 100 right after a big release! Many will be duplicates of pre-existing issues and need to be marked as such. Quite a few will be caused by issues outside of KDE’s control and this also needs to be marked as such. Many will be crash reports with missing or useless backtraces, and their reporters need to be asked to add the missing information to make the bug report actionable. And the rest need to be prioritized, moved to the right component, tagged appropriately, and eventually fixed.


↺ Debian’s Cinnamon desktop maintainer quits because he thinks KDE is better now


Norbert Preining, the maintainer of the Cinnamon desktop packages for Debian is quitting as he no longer uses it – though others have volunteered to take his place.


The origins of the Cinnamon desktop go back to 2011 and the release of the controversial GNOME 3 desktop, which introduced radical changes. Some Linux users preferred the desktop metaphor offered by GNOME 2.x, including the Linux Mint team. The MATE desktop was a fork of GNOME 2, while the Linux Mint folk made Cinnamon, a fork of GNOME 3 designed to retain the design of GNOME 2, using the Mint Gnome Shell Extensions (MGSE). Cinnamon later became a full fork of GNOME 3.


Cinnamon remains the default desktop for Linux Mint (which also offers MATE and Xfce editions), but is also available for other distributions including Debian. Mint itself is based on Ubuntu, though there is also a Linux Mint Debian edition (LMDE).


↺ Simplifying Grammar Checks for Manuals.


Like most online manuals, the Krita manual has a contributor’s guide. It’s filled with things like “who is our assumed audience?”, “what is the dialect of English we should use?”, etc. It’s not a perfect guide, outdated in places, definitely, but I think it does it’s job.


So, sometimes I, who officially maintains the Krita manual, look at other project’s contributor’s guides. And usually what I find there is…

↺ Sovereignty on a Federated System: problems we faced on GNOME’s Matrix instance


This post follows an introduction to Matrix with e-mails, where I explain that Matrix is a federated system.


Federation can be either public or private. A public server can communicate with any other server, except the ones which are explicitely avoided. Meanwhile, a private server can only communicate with a selected list of other servers.


Private federation is often deployed between entities that can trust each other, for example between universites. There often are processes to take back control of things when they derail on a server you don’t manage, because people on the remote server are contractually bound with you.


But many organisations, and especially open source projets, deploy their instance in public federation. This means strangers from the Internet can interact with your server. Public federation comes with its own set of non-technical risks.


In this post I’m going to guide you through the problems we faced on our GNOME Matrix instance. For each problem I’ll bring a solution. They will be consolidated at the end of the post in the form of a target we want to reach eventually, along with the acknowledgement of the limits of what we can do. Please note that these problems have more to do with careful planning and deployment than with the Matrix protocol itself.

↺ Hash Linux: Arch Linux Preconfigured With Xmonad, Awesome, i3, and Bspwm Window Manager


With some effort, you can install Arch Linux. You may also install a desktop environment or windows manager of your choice on your Arch system.


That takes some time and effort but it is surely achievable. However, there exists projects that try to ease the pain by providing you a system preconfigured with a desktop environment or window manager of your choice. ArcoLinux is one such example.


Recently, I came across another project that has its sole focus on providing choice of window managers on top of the wonderful Arch distribution.


Hash Project offers four preconfigured Arch variants with tiling window managers: Awesome, Xmonad, i3, and Bspwm.


If you’re a beginner window manager hopper, the Hash project is what you should definitely try at once. Without investing time to configure it first, you can explore the potential of window managers and get used to keyboard-driven systems.


In this article, I’ll discuss my part of the experience with the Hash Linux Xmonad edition featuring Linux kernel 5.12.

↺ How open source is lowering barriers to higher education


Stepping into the college experience is a whirlwind. For many people, it’s your first time away from home and one of the first times that you are tasked with managing your life on your own. There are a lot of details you need to figure out. Are you going to live on campus or off? What meal plan do you want to use? What do you want to choose as your major? What classes do you want to take? And likely most pressing, how are you going to afford everything you need?


When talking about the cost of education, there is one thing that is an issue for every student: the cost of textbooks. Textbooks for a college course can cost upwards of $100 apiece and, depending on how many courses you are taking in a semester, that can add up very quickly. In fact, the College Board found that the average university student spends more than $1,200 on books each year. For students it can be hard to justify the steep costs of books, especially when it comes to courses outside your field of study.

↺ Crowdfunding for the JingPad A1 Linux tablet begins


The JingPad A1 is an 11 inch tablet with an AMOLED display, 8GB of RAM, 256GB of storage, and support for pen and touch input as well as an optional keyboard. But the main thing that sets the JingPad A1 apart from most tablets on the market is that it runs a custom Linux-based operating system called JingOS.


Chinese startup Jingling has been promoting the upcoming tablet for a few months, and now the company has launched a JingPad A1 crowdfunding campaign with Indiegogo.


↺ Kai-Fu Lee’s Sinovation bets on Linux tablet maker Jingling in $10M round


Kai-Fu Lee’s Sinovation Ventures has its eyes on a niche market targeting software developers. In April, the venture capital fund led a $10 million angel round in Jingling, a Chinese startup developing Linux-based tablets and laptops, TechCrunch has learned. Other investors in the round included private equity firm Trustbridge Partners.


Jingling was founded only in June 2020 but has quickly assembled a team of 80 employees hailing from the likes of Aliyun OS, Alibaba’s Linux distribution, Thunder Software, a Chinese operating system solution provider, and China’s open source community.


The majority of the startup’s staff are working on its Linux-based operating system called JingOS in Beijing, with the rest developing hardware in Shenzhen, where its supply chain is located.

The upcoming PinePhone keyboard accessory will let you turn Pine64’s Linux smartphone into a tiny Linux laptop. But thanks to a recent change to the design it’ll let you do more than that.


In order to connect the keyboard to a PinePhone, you’ll remove the back cover of the phone and replace it with the keyboard case which is designed to connect to the pogo pin connectors. Some folks were hoping to be able to extend the functionality by adding more hardware. So Pine64’s Lukasz Erecinski says the latest version of the keyboard includes a breakout header that makes that possible… although not necessarily easy.

↺ The Crumble Deck is a Stream Deck alternative based on an Arduino Due | Arduino Blog


Stream Decks have gained a great deal of popularity within recent years. However, increased demand and a limited supply of them has caused their prices to skyrocket and availability to dwindle, leading many to seek alternatives. The streamer known as CoCoaCoCi has created a DIY Stream Deck before, but this first iteration only had a 3.5” touchscreen that wouldn’t always pick up inputs. So, for his next project, CoCoaCoCi wanted to have some physical buttons along with a display that would only be used to navigate menus and actions.


He started by quickly designing and 3D printing a case to house the Crumble Deck’s electronics, including an Arduino Due as the main processor, a 3.5” TFT LCD screen, and 20 buttons. All the buttons were wired together in a matrix that reduces the number of GPIO pins required to detect them. His code then polls each column and row to check which button is currently being pressed.


↺ This archery robot always hits the target | Arduino Blog


Both archery and robotics are extremely fun, but what happens when you combine the two? In Kamal Carter’s case, he constructed his own autonomous robotic archery system that can not only acquire and aim at targets, but even draw back the bow and fire an arrow all on its own.


The project features an Intel RealSense Depth Camera at its heart to acquire targets by looking for abnormally bright colors and to compute its distance away from them. This information is then fed to an Arduino Mega that uses some simple physics to determine where exactly the bow should be aimed via a pair of stepper motors. Once the target has been dialed in, another stepper pulls back the bow while a servo releases the string’s tension, thus firing the arrow.

↺ Update to the FSF and GNU’s plan to move IRC channels to Libera.Chat


Following our announcement of a planned gradual switch from the Freenode IRC network to Libera.Chat, Freenode staff, with no notice, seized control of the #fsf and #gnu channels away from FSF staff and GNU volunteers during the early hours of Sunday morning (EDT). This happened despite members of Freenode staff participating in the community meeting, as well as reassuring us publicly and privately that they would respect and support the resulting review and our decision. These channels were seized without informing the FSF or GNU representatives of any disagreements Freenode staff had with our plan, whether by means of the group contact system or otherwise. Adding to the situation’s instability was their switch to a new IRC daemon late last night, also without notice, which dropped all existing nicks and channels from the database.


This has forced us to adjust our plans for the transition, a move that was already necessary due to an abrupt change in Freenode policy that occurred shortly after our announcement, which eliminated the distinction between # and ## channels that we planned to use to pass ownership of the #fsf and #gnu channels over to the wider free software community.

How do we decide what goes into curl? And perhaps more importantly, what does not get accepted into curl?


Let’s look how this works in the curl factory.


↺ Announcing Aya


Aya was built with a focus on developer experience and operability. It does not require a C toolchain to build and doesn’t even require kernel headers. Compiling the crate in release mode takes only a few seconds.


↺ Aya: writing BPF in Rust


The first release of the Aya BPF library has been announced; this project allows the writing of BPF programs in the Rust language. “Over the last year I’ve talked with many folks interested in using eBPF in the Rust community. My goal is to get as many of you involved in the project as possible! Now that the rustc target has been merged, it’s time to build a solid foundation so that we can enable developers to write great eBPF enabled apps”.


↺ Testing cameras with lc-compliance on KernelCI


Earlier this month, the very first KernelCI sprint or “hackfest” was held virtually, with more than a dozen engineers & developers from different communities in attendance. Initiated as a joint effort by the Google Chrome OS team and Collabora, the sprint’s main objective was to extend KernelCI’s coverage, including adding new tests such as the ability to detect regressions on the Linux kernel that can directly affect cameras.


With Linux powering so many things and in so many different settings, there’s great interest in making sure that it runs well in as many of them. KernelCI fills this purpose with an ever-increasing amount of tests and environments. The media subsystem is of course no exception, and it’s just been joined by a new test suite.


↺ C++ Coroutines, or “why are the templates failing aaaaaAAAAAAA”


Qt’s networking code has always been one of its more obtuse parts, requiring using signals for something that didn’t quite seem right for them. A linear flow of code would become a jumbled mess of member functions and signal connections.


When developing Challah’s netcode, I quickly realised this wasn’t going to suffice for the large amount of it I was going to be writing. Thus begins my journey through signal hell, arriving at many bumps before I discovered that integrating Qt’s networking stuff with coroutines is possible.

↺ Tau Station considered Dangerous: Game Review


I thought I’d try out Tau Station for a couple of days and get a quick blog post out of it. That was three months and 11 levels ago. It took 2 months to wind down my obsessive nature and if not for Tau, I could have pushed a couple of new module versions to CPAN by now. That’s rather the reason that I don’t play games in the first place, so I can’t give great comparisons.


↺ Live streaming the release of Perl 5.35.1


In my talk at The Perl and Raku Conference in the Cloud 2021, I already announced it. I’m doing the release of the Perl developer version 5.35.1, and you can watch it live Sunday, 20th June on Twitch.

↺ The curious world of check digits


In many standardised numerical codes, one or more digits are special. They’re called check digits and they can be used to check that the code hasn’t changed due to human or computer error.


For example, my Australian Business Number, or ABN, is 42 021 773 747. The last nine digits are my unique identifier and the first two digits are for checking.


Rust


↺ Please welcome Boxy, Léo Lanteri Thauvin and the8472 to compiler-contributors


Please welcome Boxy, Léo Lanteri Thauvin and the8472 to the compiler-contributors group!


Boxy has been working on pushing const generics forward by implementing parts of the const_evaluatable_checked feature, fixing bugs and making rustdoc work with const generics. Boxy is also a frequent contributor to #project-const-generics discussions and meetings.


Léo Lanteri Thauvin has been a consistent contributor of refactorings and improvements to rustc. Recently, Léo has been implementing a Major Change Proposal to migrate the unsafe checker to operate on THIR instead of MIR.

↺ When will my instance be ready? — understanding cloud launch time performance metrics


Instance launch time, also called startup time, is an important performance metric for the Cloud. But what is meant by launch time? There are several related metrics that comprise launch time. In this blog post, we will describe three launch time performance metrics and explain the key components of each. Once these pieces are understood, we will describe how to build an infrastructure that measures and monitors launch time performance of cloud instances on a regular basis.


Why is launch time important? A key reason is that clouds are elastic by nature, which means that compute instances are created and destroyed in response to changes in workload demand. Hence, the time to launch instances is a critical factor in overall workload performance. Launch time metrics also help determine lead time for making instance provisioning requests, thereby playing an important role in how effective cloud elasticity is.

↺ linux.dev mailboxes for kernel work


Linux development depends on the ability to send and receive emails. Unfortunately, it is common for corporate gateways to post-process both outgoing and incoming messages with the purposes of adding lengthy legal disclaimers or performing anti-phishing link quarantines, both of which interferes with regular patch flow.


While it is possible to configure free options like GMail to work well with sending and receiving patches, Google services may not be available in all geographical locales — or there may be other reasons why someone may prefer not to have a gmail.com address.


↺ linux.dev mailboxes for kernel developers


Konstantin Ryabitsev has announced a new service providing @linux.dev mailboxes for people to use with kernel development. The documentation page has more information. “This is a BETA offering. Currently, it is only available to people listed in the MAINTAINERS file. We hope to be able to offer it to everyone else who can demonstrate an ongoing history of contributions to the Linux kernel (patches, git commits, mailing list discussions, etc).”


↺ What is an SBOM?


The National Telecommunications and Information Administration (NTIA) recently asked for wide-ranging feedback to define a minimum Software Bill of Materials (SBOM). It was framed with a single, simple question (“What is an SBOM?”), and constituted an incredibly important step towards software security and a significant moment for open standards.


From NTIA’s SBOM FAQ “A Software Bill of Materials (SBOM) is a complete, formally structured list of components, libraries, and modules that are required to build (i.e. compile and link) a given piece of software and the supply chain relationships between them. These components can be open source or proprietary, free or paid, and widely available or restricted access.” SBOMs that can be shared without friction between teams and companies are a core part of software management for critical industries and digital infrastructure in the coming decades.


↺ Adoption of a “COVID-19 Vaccine Required” Approach for our Fall 2021 Event Line-up


After careful consideration, we have decided that the safest course of action for returning to in-person events this fall is to take a “COVID-19 vaccine required” approach to participating in-person.


Security


↺ Security updates for Tuesday


Security updates have been issued by CentOS (389-ds-base, dhcp, firefox, glib2, hivex, kernel, postgresql, qemu-kvm, qt5-qtimageformats, samba, and xorg-x11-server), Fedora (kernel and kernel-tools), Oracle (kernel and postgresql), Red Hat (dhcp and gupnp), Scientific Linux (gupnp and postgresql), SUSE (postgresql10 and xterm), and Ubuntu (imagemagick).


↺ CloudLinux releases UChecker security tool for Linux servers | ZDNet


Linux is more secure than Windows. We all know that. But that doesn’t mean it has perfect security. Nothing does. CloudLinux is helping to improve Linux’s operational security with the release of UChecker. The company is best-known for its Red Hat Enterprise Linux (RHEL)/CentOS server clone, CloudLinux, and its CentOS fork.


Privacy/Surveillance


↺ Privacy Redirect To A More Friendly Alternative


Services like Nitter, Bibliogram, Open Street Maps and the countless private search engines are great but if you interact with normal people you will always end up on the original site as someone will send you a link, how about we fix that by just redirecting to where we want to go.


↺ Apple’s Subpoenas Show They Own You


Most journalists seem to miss the larger civil liberties point when Big Tech companies get subpoenas for people’s digital archives. With the most recent example being where the Justice Department subpoenaed Apple while being gagged from disclosing such a subpoena, it is time to remind nearly everybody: You don’t own your digital life, Big Tech does.


If you did own your digital files You would get the warrant not a tech giant.


“Who gets the warrant?” is as defining of the evidence of ownership as “Follow the money” is to evidence of corruption.

↺ Western Australia rushes out legislation after cops access contact-tracing data to investigate serious crimes


Police accessed COVID tracking QR check-in data to investigate a murder, causing the state of Western Australia (WA) to introduce urgent legislation in Parliament today.


The app collecting the data, SafeWA, is free, mandatory, and has been used over 245 million times for people to register their presence at relevant venues in WA. The description for the app says the data is encrypted and stored for 28 days.

↺ The Bitcoin Revolution is Here | Tech Source


Since 2014, I’ve been talking about bitcoin here (read: Is Bitcoin The Next Open-source Software Revolution?, Best Bitcoin Applications for Linux). Back then, bitcoin was still very much in its infancy and our articles about it were some of the least popular posts we’ve ever had. However, I have already seen its potential and proclaimed that it could become a revolutionary open-source software project and that it has the potential to be bigger than Linux.


[...]


After promoting Linux and other free and open-source software in the past, I have decided from now on to focus most of my time here in writing about bitcoin, cryptocurrencies, and other interesting blockchain projects. I think it is about time to enlighten people that bitcoin is not purely a speculative asset, but something that is more valuable because of its capability to empower people from around the world. Like most of you, I find joy in freedom and for me bitcoin is freedom. Now, I can safely say that the cryptocurrency revolution is underway, and we are just getting started.


Internet Policy/Net Neutrality


↺ GStreamer: IRC Channel has moved from Freenode to OFTC


Due to the widely reported issues at the Freenode IRC network, the official GStreamer discussion IRC channel has moved to #gstreamer on the OFTC IRC network alongside other Freedesktop projects.


↺ Developer chat moving


For years, most development discussion for Krita has happened on the #krita channel on the Freenode IRC network. IRC is a venerable chat system (that’s to say, it’s old and quirky) but it works very well for us because it’s free and open source software and because it treats chat as chat: it doesn’t keep logs for you if you’re not in the channel, there are many clients and interaction is simple and limited to just text.


However, the freenode IRC network is no longer a good host for our development work. The people currently managing the network are doing very strange things, and the people who used to manage the network have created a new network, libera.chat.


↺ Freenode Is IRC; As In “Dumbest Takeover In History”


Just today morning, freenode pulled the trigger on their servers and removed all channels, all users, all settings… Everything. And they say that they have restarted the network and will move to a new “fork”:


[Global Notice 1/3] We are moving past legacy freenode to a new fork. The new freenode is launched. You will slowly be disconnected and when you reconnect, you will be on the new freenode. We patiently await to welcome you in freedom’s holdout – the freenode.


[Global Notice 2/3] If you’re looking to connect now, you can already /server chat.freenode.net 6697 (ssl) or 6667 (plaintext). It’s a new genesis for a new era. Thank you for using freenode, and Hello World, from the future. freenode is IRC. freenode is FOSS. freenode is freedom.


[Global Notice 3/3] When you connect, register your nickname and your channel and get started. It’s a new world. We’re so happy to welcome you and the millions of others. We will be posting more information in the coming days on our website and twitter. Otherwise, see you on the other side!


freenode, which was the largest active IRC network, was taken over by Andrew Lee; The Korean crown prince. Former staff and volunteers say that there was absolutely no way this selling process could be legal, but due to his wealth and powerful relations, the Korean prince could not be stopped.


Until today, by his own stupidity.


The madman paid a large sum of money to buy the network – which is not yet disclosed – and then, started taking channels from their owners whenever they mentioned LiberaChat; an alternative to the freenode IRC network.


One channel after another… Almost all FOSS community migrated away in a matter of few days when the controversy started. netsplit.de showed that 30-40K users migrated to the new network in less than a week.
