Canonical, though Martin Pitt, the systemd maintainer for the Ubuntu Linux operating system, announced recently plans to unify and clean up the networking configuration in Ubuntu via a new project called "netplan."
I've been a bit behind on my file-system benchmarking the past few months but for your viewing pleasure today are some EXT4 vs. Btrfs vs. F2FS file-system tests on an NVMe SSD when testing the Linux 4.4, 4.5, 4.6, and 4.7 kernels.
The three file-systems were each tested on the latest four stable kernel series. In the next week or so I will provide some complementary figures using Linux 4.8 Git once the merge window is over and the release candidates begin. All of the file-systems were tested with the Samsung 950 PRO M.2 NVM Express SSD.
I have a 128GB micro SD card that I'd like to blow away. I use the card for my dashcam and it failed to format for me, so I am trying to manually wipe it and format it to FAT32. However, it seems that the card (with no physical lock) is write protected, and won't allow me to write to it, no matter what. Help!

The upcoming Ubuntu 16.10 (Yakkety Yak) operating system is currently in development, with a second Alpha build seeded to public testers at the end of July 2016.
Canonical, through April Wang, is pleased to announce that the Snappy Ubuntu Core operating system for embedded and IoT (Internet of Things) devices is now officially available for the Bubblegum-96 single-board computer (SBC).
The conundrum for many enterprise-level businesses is that the demand for data storage is significantly outpacing the shrinking price for storage. The upshot for many is that budgets for storage are growing faster than data demands. Fortunately SUSE wants to reduce your storage costs, which is why it released the new SUSE Enterprise Storage 3.
The developers of Toutou, a minimalist GNU/Linux distribution based on Puppy Linux, are continuing the development of the Toutou Linux 6.3.2 "SlaXen" release with a second Alpha milestone.
GNU/Linux developer Arne Exton has released a new version of his Ubuntu-based Exton|OS operating system, build 160728. The Exton|OS Light edition has been updated, which uses the Openbox window manager.
So I am getting back into coding (C++) and I LOVE the look of sublime text, and was wondering if there are any ways to make it into basically an IDE, or at least a compiler. Maybe there is another IDE with that kind of A E S T H E T I C? I.E. dark backround with white text. Thanks!submitted by /u/-Tilde

ZeMarmot at GUADEC 2016
We are all happy users of GNOME here, and this is the first time we will be in GUADEC, so this is pretty exciting. Both Aryeom, the film director, and myself, Jehan, are sponsored by the GNOME Foundation to present our film, produced with FLOSS, in room 1, on Sunday, August 14. We will talk about the movie, its current status, about our work on GIMP too, how GNOME and Free Software works in a media creation workflow, and so on. So we hope you will be many to check this out if you are around!
