Wayland is an interesting beast. X11, for all its faults, does a lot for the desktop environment. If you’re stretched for time, you could – in theory – just slap a panel onto the default X11 window manager and call it a day. The modern landscape of desktop environments built on top of X11 exists because developers have gotten really good at eschewing X11’s built-in crusty junk for their own new and shiny junk, so that things work as you’d expect them to. For the most part, this kinda works – with enough hacks, you can get things like variable refresh rate, fractional scaling, et cetera. The problem here is that X11 definitely was not built for those things. Variable refresh rate works, but only if you’re using a single monitor, and mixed refresh rate monitors in a single X session don’t work at all outside of the hardware cursor. Fractional scaling is a hack. Compositing in general is optional and is sort of just stapled onto the existing architecture. X11 does do what it needs to do, which is display windows, but it’s kinda garbo when you need it to do anything more advanced. Wayland is what happens when issues with the dominant windowing protocol have been festering for decades. It throws away everything and establishes a core set of standards that must be adhered to, along with a (very large) set of extensions that can be optionally implemented. The website https://wayland.app/ shows all the protocols worth knowing, and a lot more on top of that. It’s kinda like Vulkan, in a sense: the core has the basics, and everything else is extensions that can be queried for by clients. Wayland is such a massive improvement over X11 it absolutely boggles the mind that people try to claim otherwise. I’m glad we’re finally at a point where Wayland has clearly won, and developers are finally free to focus their efforts on the clearly superior choice, instead of wasting more time trying to hack X11 into the 21st century.

For our first sponsored contribution time, we will be focusing on efforts to improve the usability of Drupal’s administration UI. We chose this because there are some deliverables we beleive we can achieve within six months that will make Drupal better and benefit our existing clients.

This is not Ruby-specific, but if you are creating a GitHub repo for your next Ruby project, you’ll want to review the following best practices: Improve your GitHub workflow with better repository defaults. Includes a quick introduction to some interesting low-level features of the gh CLI.

We have released the uri gem version 0.12.2, 0.10.3 that has a security fix for a ReDoS vulnerability.
This vulnerability has been assigned the CVE identifier CVE-2023-36617.

Details

A ReDoS issue was discovered in the URI component through 0.12.1 for Ruby. The URI parser mishandles invalid URLs that have specific characters. There is an increase in execution time for parsing strings to URI objects with rfc2396_parser.rb and rfc3986_parser.rb.

NOTE: this issue exists becuse of an incomplete fix for CVE-2023-28755.

The uri gem version 0.12.1 and all versions prior 0.12.1 are vulnerable for this vulnerability.

Recommended action

We recommend to update the uri gem to 0.12.2. In order to ensure compatibility with bundled version in older Ruby series, you may update as follows instead:

• For Ruby 3.0: Update to uri 0.10.3
• For Ruby 3.1 and 3.2: Update to uri 0.12.2

You can use gem update uri to update it. If you are using bundler, please add gem "uri", ">= 0.12.2" (or other version mentioned above) to your Gemfile.

Affected versions

• uri gem 0.12.1 or before

We are happy to announce the publication on “Practical Offline Payments Using One-Time Passcodes” by The European Money and Finance Forum.

This is a wee operating system written to support the async style of programming in Rust on microcontrollers. It fits in about 2 kiB of Flash and uses about 20 bytes of RAM (before your tasks are added). In that space, you get a full async runtime with multiple tasks, support for complex concurrency via join and select, and a lot of convenient but simple APIs. I understood some of those words.
