• XKCD Forum Hacked — The security breach occurred two months ago, according to security researcher Troy Hunt who alerted the company of the incident, with unknown hackers stealing around 562,000 usernames, email and IP addresses, as well as hashed passwords.
• Examining exFAT — Linux kernel developers like to get support for new features — such as filesystem types — merged quickly. In the case of the exFAT filesystem, that didn't happen; exFAT was created by Microsoft in 2006 for use in larger flash-storage cards, but there has never been support in the kernel for this filesystem. Microsoft's recent announcement that it wanted to get exFAT support into the mainline kernel would appear to have removed the largest obstacle to Linux exFAT support. But, as is so often the case, it seems that some challenges remain.
• Waypipe Is Successfully Working For This Network-Transparent Wayland Apps/Games Proxy — Waypipe development was successful this summer by student developer Manuel Stoeckl who was working on the effort as part of this year's Google Summer of Code (GSoC). Waypipe is successfully working now for running Wayland games/applications over the network using this proxy mechanism and supports features like compression, multi-threading optimizations, and hardware-accelerated VA-API for video encode/decode across the network.
• GSOC 2019 - M. Stoeckl's website — Waypipe supports many quality of life features, including a user-friendly command line wrapper for ssh, hardware accelerated video encoding, transfer compression with either LZ4 or Zstd, and a method to reconnect applications when the ssh connection breaks. With more recent kernels and versions of Mesa that support DMABUFs (GPU-side buffers), it can proxy programs that render images using OpenGL.

• GNOME 3.34's Mutter Lands A Last-Minute Performance Fix For NVIDIA — Canonical's Daniel van Vugt who is known for his many GNOME performance optimizations over the past two years has been toying with this NVIDIA fix/optimization the past few months and merged the code this morning to Mutter. This change that landed is the removal of GLX threaded swap wait handling for the NVIDIA binary driver.
• Geometric Picking Finally Lands In GNOME/Mutter 3.34 For Lowering CPU Usage — This is about cursor movement and now avoiding OpenGL/GPU usage for the color picking operations. That logic is now being done on the CPU without OpenGL but turns out is more efficiently done this way and is able to cause a measurable drop in CPU usage when moving the mouse cursor and especially when moving around windows.
• Geometric (OpenGL-less) picking · GNOME / mutter · GitLab) — By avoiding OpenGL and the graphics driver we also reduce CPU usage. Despite reimplementing the logic on the CPU, it still takes less CPU time than going through GL did.
• GTK, Adwaita, and Vendor Styles - Platform - GNOME Discourse — After the BoF, we decided to continue the discussion and find actionable items to move things forward to improve Adwaita itself, the situation for app developers, and the experience for downstream vendors that wish to ship a distinct visual style. We decided that continuing here on Discourse is a good plan to keep the discussion persistent and centralized.
