The kernel's filesystem mailing list has received an 18-patch proposal this week from Aurelien Desbrieres, the creator of BeamFS. It takes the place of FTRFS, an earlier filesystem he had proposed back in April.
Aurelien says he used Anthropic's Claude to write the code, the tool that checks the patches, and the cover letter.
He also points out that every patch carries an Assisted-by tag. You might remember that is the disclosure the kernel's AI coding assistants policy asks for. The same policy keeps the human submitter responsible for the code.
How does it fix data?
Filesystems that can repair damage, like Btrfs and ZFS, usually do it by falling back on a spare copy of the data. BeamFS skips that and stores Reed-Solomon error-correcting codes inside every block.
Every read gets checked against those codes, and small amounts of damage are corrected before the data reaches the application. If the filesystem can tell the damage is beyond repair, the read fails with an error instead of returning the wrong bytes.
The idea started with satellite computers. They keep data on a single drive and cannot fit a second copy. The same case is made for radiotherapy rooms.
Neutrons from treatment machines can flip bits in the computers there, including the ones handling imaging and records. Aurelien argues a silently wrong byte does more damage in that setting than a failed read.
BeamFS has not been tested in a real radiation environment yet. The tests done so far simulated the damage by flipping single bits in data as it was read on virtual machines and USB flash drives.
In his technical report, ext4 and ext3 returned wrong data without any error, while Btrfs refused to read the file. BeamFS returned the correct file every time except once, when a flip hit a pointer to the file’s data and it refused the read.
Do keep in mind that the comparison is uneven. Each filesystem received a different number of flips, and the report makes it clear that it is not a ranking.
Is it close to landing?
Nope, this is a request for comments (RFC). Aurelien is asking for feedback, not calling for a merge, and he has two questions for the maintainers.
The first is whether it should be a separate filesystem or be proposed for an existing one.
The second is the journal, the log other filesystems use to recover from crashes. BeamFS lacks one and relies on its fsck tool after an unclean shutdown. Aurelien asks whether it has to come before further review or can be submitted afterward.
So far, the only reply in the thread is about where the MAINTAINERS entry sits alphabetically.
The project's README has a warning of its own. It lists bugs that can lose data, open security holes, and crash the kernel, advising against trusting the code with anything important.
Steam’s Linux client is going 64-bit and containerized. Running the client inside Steam Runtime containers, like its games already do, should make it behave more consistently across different distros.
Ubuntu 26.10 is out now. This interim release completes the rustification of core utilities, adds Sequoia PGP to the main archive, and brings Linux 7.3 with Snapdragon X2 Elite support and better GPU memory handling.
Fedora 45 release is delayed, and it should now be released on 30th October.
CutefishOS is making a comeback with a completely rebuilt desktop written using Anthropic’s Fable and Opus AI models. Ships with its own Wayland compositor and graphics library, skips Qt and GTK entirely, and launches apps quickly.
Dux Labs is the new name for Dank Linux and its Wayland suite, now that DMS has grown beyond a single product. The rebrand coincides with DMS 2.0, which adds Material 3 design, a new file manager, and widget support.

🧑🤝🧑 From the Community: Pro FOSSer Mikael is looking for a printer that is compatible with Linux. Got any suggestions for him? 🖨️❓
I spend a lot of time in the terminal. Whether it is writing scripts, editing configuration files, or managing remote servers, the terminal remains the place where I get most of my work done. But when a project becomes slightly complex, I often find myself reaching for the comfort of a graphical code editor like Zed.
I'll be honest, while I can appreciate why people love tools like Vim and Neovim, learning a modal editor has always felt like more of a commitment than I was willing to make.
My editing needs are fairly straightforward, and spending hours memorizing keybindings, configuring plugins, and building a workflow from scratch never felt like a worthwhile investment for me.
That's why TTT caught my attention. The project describes itself as a real alternative to VS Code, Zed, and Sublime Text that runs entirely inside the terminal.
✋
Like most of the new open source software, TTT is also developed with the help of AI assistants.
Installing TTT
On Linux, to install TTT, you can use the official installer script. That's fashion these days. No package, just an installer script curled right into your system.
curl -sSfL https://raw.githubusercontent.com/eugenioenko/ttt/main/install.sh | sh
This will install the binary in ~/.local/bin. To run it, open your favorite terminal and use the command:
ttt
There are also prebuilt binaries available to download so that you can place it in a folder of your choice and use it in portable mode.
TTT features I liked
Instead of trying to emulate traditional terminal editors, it aims to provide a modern, GUI-like editing experience in the terminal application with virtually no configuration required.
Sure, not all of these features might be unique, but they are good to have in an editor.
Syntax Highlighting
TTT uses textmate-go for syntax highlighting, a Go implementation of Microsoft's TextMate engine that powers syntax highlighting in VS Code. It claims to support more than 120 languages out of the box, giving it a surprisingly mature editing experience for a terminal-based application.
Syntax Highlighting
Multi-Cursor Editing
Multi-cursor editing is one of those features I started appreciating after spending some time with Helix. It's something I now instinctively look for in any editor.
Thankfully, TTT ships with multi-cursor support out of the box, so there's no need to install plugins or configure anything before getting started.
The workflow feels familiar if you've used modern editors before, like Sublime Text.
Pressing Ctrl+D selects the next occurrence of the highlighted text, while Alt+Click lets you place additional cursors exactly where you need them.
Multi-Cursor Editing
Mouse Support
Many terminal editors advertise mouse support, but often that simply means you can click around and scroll. TTT goes much further than that.
The mouse interactions felt surprisingly close to what I'd expect from a graphical editor rather than a typical terminal application.
You can click to position the cursor, drag to select text, and right-click to access context menus.
0:00

Mouse Support in TTT
The latter ended up being my favorite part because the menu isn't just a generic list of actions. Depending on where you click, TTT presents relevant options, making the whole experience feel far more polished and GUI-like than most terminal editors I've tried.
LSP and Auto Completion
A code editor doesn't feel complete these days without intelligent auto-completion, and TTT checks that box through Language Server Protocol (LSP) support.
Getting it up and running is fairly straightforward as you only need to install the language server for the programming language you work with.
Once configured, you get the kind of code completion and language-aware features you'd expect from a modern editor, but without leaving the terminal.
LSP Autocompletion
Multi-folder Workspaces
Multi-folder workspaces allow you to group related folders into a single workspace and treat them as one project, much like VS Code's multi-root workspaces.
What makes this even more useful is that the workspace can be saved to a workspace.ttt file and reopened later with the exact same setup. So instead of manually opening the same collection of directories every time, you can simply load the workspace and continue where you left off.
For example, I have this customization.ttt file that has the content:
Now, I can always open this workspace by using the command:
ttt --workspace ~/Projects/customization.ttt
You don't need to manually create this file since you can add location to a workspace and later save it all via File -> Save Workspace As option.

Multifolder Workspaces
Modern Search with Ripgrep
TTT uses ripgrep under the hood, which is already a favorite among developers thanks to its speed and ability to handle large projects without feeling sluggish.
In practice, this means you get fast, project-wide search capabilities directly inside the editor.
Combined with shortcuts like the Ctrl+K F for workspace search and Ctrl+K R for search and replace, it feels much closer to the experience you'd expect from a modern GUI editor than a typical terminal-based tool.
Search in TTT
💡
You need to have ripgrep installed on your system.
Git Integration
TTT provides a dedicated Changes panel where you can stage, unstage, discard, commit, pull, push, and sync repositories without dropping back to the command line.
The built-in diff viewer is particularly nice to work with because it combines Git diffs with syntax highlighting, making code changes easier to read.
The Git gutter indicators and inline blame information help provide context while editing.
If you're working with multiple repositories in a workspace, TTT automatically groups changes by repository, which keeps things organized when juggling several projects at once.

Git Integration
Integrated Terminal
You may find it funny that one of my favorite features in a terminal-based editor is... another terminal. But in practice, I found it incredibly useful.
Whenever I needed to run a command, I didn't have to open a split terminal in my terminal emulator or switch to another tab. Everything stayed inside TTT, which helps maintain focus on the task at hand.
TTT's integrated terminal is a full terminal emulator rather than a basic command prompt. It supports multiple terminal tabs, true-color rendering, scrollback, and can be toggled between panel and fullscreen modes with keyboard shortcuts.
For a project that aims to bring a GUI-like experience into the terminal, this feature fits perfectly, eliminating one more reason to leave the editor while working.
0:00
/0:41
Integrated Terminal
Plugins
TTT already comes with many of the features I normally install plugins for in other editors. But the more I explored it, the more I appreciated the approach.
TTT supports Lua-based plugins that can add commands, panels, and keybindings, allowing you to extend the editor without turning it into a configuration project.
Plugins run inside a sandboxed environment and must explicitly request permissions to approve each plugin's capabilities.
To add even more convenience, you can install plugins through a dedicated panel within the TUI.
TTT ships with a decent collection of built-in themes, including popular options like Dracula, Monokai, etc., making it easy to find something comfortable without downloading anything extra.
The built-in theme picker offers live previews as you browse themes, and you can customize virtually every aspect of the interface through JSON files, from syntax highlighting and diff colors to the sidebar, status bar, and even terminal colors.
Themes in TTT
Wrapping Up
After spending some time with TTT, my biggest takeaway isn't that it's a great terminal editor. It's that this thing often doesn't feel like a terminal editor at all. In many ways, it feels like a full-blown GUI application that just happens to live inside a terminal window.
Now, I don't know how many of you will actually approve of that direction. The Linux and terminal communities have long maintained a clear distinction between TUIs and GUIs, and plenty of users prefer terminal applications precisely because they don't try to mimic desktop software. TTT deliberately blurs that line. Whether that's a good thing or not will ultimately depend on what you want from a terminal editor.
I found TTT's approach refreshing. It takes many of the conveniences people expect from modern GUI editors and brings them into the terminal with surprisingly very few compromises. If that idea sounds appealing, TTT is absolutely worth a look.
Brax Technologies, the company behind the BraX3 smartphone and the open_slate tablet, opened pre-orders for the Wink last week with plans to ship it in two batches next year.
The Wink runs BraxOS, an Android-based operating system that does not include Google services, and the device comes with a physical switch located on top that can be configured to shut off the camera, microphones, location, sensors, or mobile network.
During setup, you can pick between Omni, a full Android experience, and Zero, a stripped-down mode limited to encrypted messaging, calls, messages, and optional navigation.
BraxOS does not support Google account sign-ins or Google Play Services, but Brax says most Android apps still run without issues. The exceptions are apps that check for Google's integrity services before starting, which includes a few banking apps.
The Wink can also wipe itself on triggers you set in advance, namely every restart, a long stretch powered off state, repeated failed unlock attempts, and a duress password.
Brax promises updates until 2032 and says anyone can build BraxOS from source, with files available in its BraX3 repositories.
Key specifications
Coming back to the hardware that powers all that, we have:
SoC: MediaTek MT8875 with an octa-core CPU (4x Arm C1-Pro and 4x Arm C1-Nano cores, 4 nm) and an Arm Mali-G625 MC2 GPU.
Keyboard: Physical QWERTY keys that are touch-sensitive and support swipe scrolling.
Networking: Global LTE and 5G bands, plus physical SIM and eSIM support.
Connectivity: Wi-Fi 6E and Bluetooth 5.4.
Ports: USB-C 3.2 Gen 1, a 3.5 mm headphone jack, and a microSD slot for cards up to 1 TB.
Getting the device
Pre-orders come in two batches, each capped at the number of units being built:
Batch 1 is for buyers who pay in full at $449, a price Brax guarantees, and those units go out first in July 2027.
Batch 2 starts with a $30 deposit toward a $550 total. The remaining $520 would be charged around July 2027, with these units shipping in September 2027.
The deposit amount is refundable until the balance is paid, and orders can be changed or cancelled while they are still reservations. Shipping dates can also change, and reservation holders will be emailed about any change before the remaining amount is due.
Each unit is set to ship with the keyboard, a USB-C cable, and a translucent case.
What I realized in the past week or so is that if you can reverse engineer it, any software is open source software.
Not in the license sense, of course. But AI agents are getting good at reading binaries, tracing what an app does and rebuilding it. Last issue, we had the Craft tools cloning Microsoft Office. This week, there are more office clones, a viral repo that reverse engineers "anything", and people taking back control of their smart TVs with the help of AI.
The source code is no longer the wall it used to be. Whether that's a good thing depends a lot on which side you are on.
🧪 On my desk
I have enjoyed using Myna for voice based input on Ubuntu 26.04 (yes, it can be installed on 26.04). The performance is surprising good. Next, I will be trying a few more such voice input tools, starting with SpeakoFlow.
🔍 Discover AI tools
REA (Reverse Engineer Anything) is the repo of the week. It's an MIT-licensed MCP server that lets AI agents inspect native binaries, Electron apps, Android APKs, firmware and more. Deep native analysis needs proper reverse engineering tools like Ghidra. Analysis runs locally, but your agent's model provider still sees what it finds. Also, fake REA repos are already serving malware, so install it only from the official repo or npm package.
Graphify is reverse engineering for your own code. It turns a codebase, docs and PDFs into a knowledge graph your coding agent can query. Code is parsed locally with tree-sitter, and GRAPHIFY_BACKEND=ollama keeps the rest local too.
It's a Plan is a self-hosted Linear/Jira alternative where AI agents get a role and pick up issues like any team member. External agents run on your machine and hand tasks to Claude Code, Codex or opencode. In early stages for now.
🏢 The office clone wars
Mandrake Linux creator Gaël Duval is behind ElixirOffice, a Microsoft Office look-alike built on Euro-Office components. The code was written by LLM agents, with tests and reviews on every change. It's AGPL-3.0 and in beta.
Then there is Ely Office, six offline desktop apps for documents, sheets, slides, PDF, Git and Markdown.
And BetterOffice, which we covered last week, now has its Apache-2.0 source under the openooxml org on GitHub.
Meanwhile, Perplexity added REA to its Computer agent as a /reverse-engineer command, free until 31 October. Its demo clones included Photopea, Audacity and... LibreOffice Calc. Yes, reverse engineering an app that is already open source (LOL).
📺 Your TV, your rules
My favorite story of the week. Android TV owners are using AI to debloat their smart TVs. The agent connects over ADB, lists installed packages and disables ads, telemetry and preinstalled junk. People report faster TVs. A related project does the same for Fire TV.
This is the "reverse engineering" idea at its most useful. You don't need to be an Android developer anymore to fix the device you paid for.
📡 Open Model News
Meta released Muse Spark Open, an 816B model with 42B active parameters and a 1M-token context. The headline says it "runs on Macs". But that actually means two Mac Studios with 512 GB each. Not the kind of hardware normies like me can afford.
Also note the licence. It's the "Muse Model License" with limited commercial terms. Open weights, yes. Open source, no.
👀 Big Tech Watch
NVIDIA RTX Spark laptops went on sale on 16 October, starting at $2,599, from ASUS, Dell, HP, Lenovo, Microsoft and MSI. The chip pairs a Blackwell GPU with a Grace Arm CPU and up to 128GB of unified memory, enough for bigger local models on a laptop. Two catches. The 128GB is only on the top configuration, and the lower tier tops out at 32GB. And these are Windows on Arm machines, with no word on native Linux support (yet).
Google Research open sourced Harness², a framework that improves the harness around a model (prompts, tools, memory, skills) without touching its weights. It's Apache-2.0 and uses OpenCode by default. Model runs are configured for Vertex AI, and I see no documented local model path yet.
Anthropic says Claude Code now gzips the conversation it sends on every turn, and cloud sessions start as soon as you begin typing. It reports up to 3x faster time to first token for local Claude Code sessions, compared with August. The billion-dollar AI speedup came from gzip, a free and open source software tool from 1992.
🗂 AI Jargon: Clean-room design
How do you copy software legally? Clean-room design.
One team studies the original app and writes down only what it does: the behavior, the file formats, the interfaces. A second team, which has never seen the original code, builds a new app from that description. That separation is what protects the clone from copyright claims. It's how the PC BIOS was cloned in the 1980s and that's how Compaq became a popular PC brand.
AI agents blur this neatly. The same agent that reads the binary often writes the new code. Whether that still counts as a clean room is a question lawyers will be busy with for a while.
😂 Meme
⚡ Quick Tip: Back up before an agent touches your TV
Before you get too excited and let an agent debloat your Android TV, save the package list first:
adb shell pm list packages > tv-packages.txt
Ask the agent to use pm disable-user instead of uninstalling. A disabled package comes back with adb shell pm enable <package-name>. And turn off USB or wireless debugging when you are done. An open ADB port on your home network is not something you want to leave lying around.
And if you must use cloud AI for something sensitive, Maple has a sensible guide to using AI privately. Maple sells a private AI service, so keep that in mind. The thing is that privacy settings alone don't stop a provider from reading your chats. Running models locally is still the only option that keeps your words off someone else's server.
Dank Linux, the Wayland desktop suite built around DankMaterialShell (DMS), has put out its final post on X under that name, bidding farewell to its old identity. Accompanying it is DMS 2.0, codenamed "Heisenberg," which reached GitHub just a few hours ago.
If you didn't already know, the shell is a Quickshell and Go project that stands in for tools like waybar, swaylock, mako, and fuzzel. Around it sit a greeter, a calendar app, a system monitor, and a search service.
It began as a hobby project, with 1.0 shipping in December last year. Since then, newer releases have added niceties like desktop widgets, a new launcher, and spring-based motion.
With that many components in the suite, the project has now put all of them under a new name.
A surprise rebrand
The rebranding covers the whole suite. DMS is now Dux Shell, and the greeter, search tool, system monitor, and calendar are now Dux Greeter, Dux Search, Dux GOP, and Dux Calendar, respectively.
Dank Linux gets renamed Dux Labs, which also acts as the new name for the project as a whole and for every app in the suite.
Dux Files is a standalone file manager that is the one piece that's new instead of being renamed. It offers features like tabs, split views, trash, and network shares. It picks up your DMS theme if the shell is running.
Dux is the suite's mascot, and the name echoes Linux's penguin mascot, Tux. Starting with a D also lets the dms, dcal, and dgop commands keep their names.
The project's reasoning to go through the rebrand is that a name built around one product no longer fits a suite with its separate collection of apps and a plugin community.
Another thing to note is that the earlier release, DMS 1.6, still carried the Dank name, and its roadmap listed a standalone file browser and phone integration, but a rename was never really mentioned.
As for the DMS 2.0 release, it is a packed one that adds a Material 3 Expressive redesign, plugins for the dashboard and dock, and a lock screen with widgets you can arrange yourself.
It also adds Dux Dot, a free-floating companion or replacement for the bar that can turn into notifications, weather, media, and wallpaper views, as well as the control center, dashboard, and launcher.
What now?
The project has already moved from the AvengeMedia umbrella to a new GitHub organization called Dux Labs.
You will find many repositories that used to be known by their Dank names, including dux-shell (previously DankMaterialShell), dux-gop (dgop), dux-search (danksearch), dux-calendar (dankcalendar), and dux-greeter (dank-greeter).
Personally, I preferred the Dank branding. But if the developers feel this is the best approach and the community accepts it, there's no point talking about what was.
If you have been planning to get a certification, this is the week to do it. The Linux Foundation is running its Cyber Security Month promo, and you can get up to 40% off on cyber security certifications, training courses and the THRIVE-ONE e-learning subscription.
Linux Foundation is the official organization behind Linux, Kubernetes, and many other industry-facing projects. Their certifications are well respected across countries and enterprises.
The offer ends on October 23, 2026 at 23:59 UTC. That gives you just a couple of days to make up your mind.
The good thing is that you have one full year to take the certification exam. So, you can purchase the cert exams today to save the money, prepare in a few weeks/couple of months and then attempt the exam.
There is also a 3 day money back guarantee with some conditions. Please read the policy here.
This article contains affiliate links. Please read our affiliate policy.
Your discount codes
Here are the codes. They are specific to It's FOSS readers, so use these and not the generic ones you see on the promo page.
So if you are eyeing CKA, LFCS or any other Linux Foundation certification that is not in the cybersecurity list, you still get 35% off with the second code.
Even if the offer ends, you can always get 30% off with our special coupon code: ITSFOSS.
💡
Apply the code on the checkout page. The discount is for new, individual purchases only and cannot be combined with other offers.
Kubernetes Security Certifications
The biggest savings this time are on the Kubernetes security certifications. Here are the ones worth looking at.
KCSA + CKS bundle: $645 $387
This bundle groups two certification exams together: Kubernetes and Cloud Native Security Associate (KCSA) and Certified Kubernetes Security Specialist (CKS). You save $258 over the regular bundle price.
KCSA is the entry-level, multiple choice exam. CKS is the hands-on, professional one. Taking them in this order makes sense, as KCSA builds the foundation that CKS expects from you.
Keep in mind that you must have passed the Certified Kubernetes Administrator (CKA) exam before you can take CKS. If you don't have CKA yet, you can grab it with the 35% code OCT26NONCYBERFOSS.
You can also choose to get either of the certification exams instead of the bundle. But if you are getting both, the bundle saves you additional money.
CKS is a 2-hour, performance-based exam. You solve real tasks on a live Kubernetes cluster from the command line, so there is no guessing your way through multiple choice options.
You also get two sessions on the Killer.sh exam simulator to practice in an environment similar to the real exam. The certification is valid for 2 years. As mentioned above, an active CKA is a prerequisite.
Kubernetes and Cloud Native Security Associate (KCSA): $250 $150
KCSA is a pre-professional certification for people starting out in cloud native security. It is a 90-minute, online proctored, multiple choice exam with no prerequisites.
At $150, this is the most affordable way to get a Linux Foundation security certification on your resume this month. You save $100.
THRIVE-ONE is the Linux Foundation's subscription. The annual plan gives you unlimited access to the entire e-learning catalog for a year, plus all SkillCred exams.
You also get a 40% coupon for any certification or course and 50% off guaranteed-to-run instructor-led courses. Note that certification exams themselves are not included in the subscription.
This works well if you want to learn several technologies over the year instead of focusing on one exam. The 30% discount applies to new subscriptions only.
I get asked this a lot. Are Linux certifications worth it?
A certification is a way to prove to a recruiter that you have the skill. Anyone can list "Kubernetes" or "Linux administration" on a resume. A certification from an industry-recognized body like the Linux Foundation tells the hiring manager that someone has actually tested you on it.
This matters even more for performance-based exams like CKA, CKS and LFCS. You don't pick answers from a list. You fix real problems on a live system within a time limit, which is pretty much what the job looks like.
Certifications are even more helpful if you are a fresh graduate, or if you are switching to a new domain like cloud native or security.
And it is not just my opinion. In the Linux Foundation’s 2026 State of Tech Talent report, 76% of organizations said they value certifications when assessing candidates for a technical role. That is slightly ahead of college degrees at 74%, and this is the third year in a row that certifications have ranked above degrees.
You don't have to take the exam this week
This is the part a lot of people miss. You only need to buy the certification before October 23. You don't need to take the exam right away.
Linux Foundation certifications come with 12 months of exam eligibility. You can schedule and take the exam any time within a year of purchase. So you can lock in the discounted price now and prepare at your own pace.
Most certifications also include one free retake. If your first attempt does not go well, you get a second chance without paying again. That's a big relief, in my opinion.
Missed the deal? Use our evergreen code
If you are reading this after October 23, don't worry. It's FOSS readers have a code that works any time, even when no promo is running.
💡 Use the code ITSFOSS to get 30% off on Linux Foundation certifications, e-learning courses and bundles. Valid all year round.
