It chains two flaws, neither of which can work alone. Luckily, [fixes have arrived for it in the Linux kernel](https://itsfoss.com/news/linux-fully-patches-dirty-frag-exploit/), as well as Fedora and Pop!\_OS. I suggest you make the necessary updates or risk being open to a highly publicized exploit. Seeing the rise of such exploits, there is now a new kernel proposal called [killswitch](https://itsfoss.com/news/linux-killswitch-proposal/), which would allow system administrators to disable a vulnerable kernel function at runtime. In addition to that, there is a proposal for a scheduler in kernel that promises [frame time improvements on aging hardware under heavy CPU load](https://itsfoss.com/news/linux-scheduler-patch-gaming-old-hardware/). A few weeks ago, we reported about LVFS turning up the heat on vendors who didn't pay their fair share. Now, [Dell and Lenovo have both signed on](https://itsfoss.com/news/lvfs-finally-has-premier-sponsors/) as *Premier* sponsors at $100,000 a year each, making them the first vendors to reach that tier. Ubuntu announced local-first AI plans, and now [Fedora has approved its own AI Developer Desktop initiative](https://itsfoss.com/news/debian-makes-reproducible-builds-mandatory/) with a unanimous council vote. Three Atomic Desktop images are planned, two of them CUDA-enabled, and none of them would be phoning home to cloud services. Fedora has also announced [Hummingbird](https://itsfoss.com/news/fedora-hummingbird-images/), a distro that ships the entire OS as a bootable OCI image with atomic updates and rollback support. Debian [has made reproducible builds a hard requirement](https://itsfoss.com/news/debian-makes-reproducible-builds-mandatory/) for the Forky cycle. Since May 9, any package that can't be compiled byte-for-byte identically from its source is blocked from entering testing. **Here are other highlights of this edition of FOSS Weekly:** - How moving away from OneDrive looks like. - Yazi file browser (that I missed to include last week). - A Ratatui terminal. - And other Linux news, tips, and, of course, memes! ## ๐Ÿง  What Weโ€™re Thinking About My colleague Sourav, a long-time OneDrive user, had to move away from it over fears of Copilot messing around with his photos and videos. [Ente Photos was the alternative he went for](https://itsfoss.com/moving-from-onedrive-to-ente-photos/). [I Moved My Photos from OneDrive to Ente Photos, and Iโ€™m Not Going BackPrivacy concerns drove me to move 20,000+ photos and videos out of OneDrive.![](https://itsfoss.com/content/images/icon/android-chrome-512x512-413.png)It's FOSSSourav Rudra![](https://itsfoss.com/content/images/thumbnail/onedrive-migration-to-ente-banner.png)](https://itsfoss.com/moving-from-onedrive-to-ente-photos/) ## ๐Ÿงฎ Linux Tips, Tutorials, and Learnings [Yazi](https://itsfoss.com/yazi/) is a Rust-based terminal file manager that does a lot more than `ls` and `cd`. You get a three-pane layout, image previews, syntax-highlighted code previews, and archive peeking without extraction. Most KDE users know Dolphin does split view and tabs. [Fewer know](https://itsfoss.com/dolphin-tweaks/) it can verify file checksums, restore recently closed tabs with `Ctrl+Shift+T`, and paste images directly from the browser. If you have been eyeing a move to Fedora, then our [Getting Started with Fedora](https://itsfoss.com/fedora-tutorials/) series is the one for you. This curated resource page covers everything from first boot to enabling RPM Fusion, NVIDIA drivers, Steam setup, and upgrading between versions. ## ๐Ÿ‘ท AI, Homelab and Hardware Corner Sanctions pushed Huawei to build their own mobile OS.

Terminal can be fun. Terminal can be weird. This week, we [came across a new terminal](https://itsfoss.com/ratty-terminal/) that is amusing, absurd and fun. It shows terminals can have 3D effects. [This New Terminal is Absurd (But Totally Fun)Not every day you come across something absurd and fun and amusing at the same time.![](https://itsfoss.com/content/images/icon/android-chrome-512x512-416.png)It's FOSSSreenath![](https://itsfoss.com/content/images/thumbnail/ratty-terminal.webp)](https://itsfoss.com/ratty-terminal/) If you live in the terminal and use Discord, [Concord](https://github.com/chojs23/concord?ref=itsfoss.com) can be a TUI client replacement for it.

First, open two files in separate tabs. Then, *right-click* on the title of the inactive tab and select the "*Compare it with Active Documen*t" option. This will open a new tab, highlighting the differences between the files. ![](https://itsfoss.com/content/images/2026/05/kate-compare-1-right-click-and-select-compare.png) ![](https://itsfoss.com/content/images/2026/05/kate-compare-2-diff-sepearte-tab.png) [](https://t43217012.p.clickup-attachments.com/t43217012/da09f1e7-b651-4c93-b93b-141e46671d4b/copy-link-to-highlight-firefox.png?ref=itsfoss.com) ## ๐ŸŽ‹ Fun in the FOSSverse Do you know all the Apt commands?
