Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

external USB keyboard on RM2? does this hack still work?
My comment is for a Remarkable 2. You need to SSH to it, tweak the USB port so it receives keypresses, and use some form of powered hub (or a hub powered by a battery, i.e. something to power your keyboard) to plug your keyboard; then it works. At least, I could type to create folders, which is what I tried last weekend. I was using a USB-C hub by Anker I usually use with my Mac: it has a dedicated "in" PD (power delivery) USB-C port, which I used to power it. My goal was trying keywriter, but there seems to be a problem with the current build, and I didn't have the patience to build from source either on a machine or the Remarkable (since I could not install Toltec). If that was not the case, basically the steps here work.

The Modos Paper Laptop
If anyone, like me, wants a distraction and eye-strain-free writing device, your best option right now is probably a ReMarkable Tablet + third party software + keyboard plugged in via USB OTG.
Take a look at Keywriter: https://github.com/dps/remarkable-keywriter
Stick it in a 3D printed clamshell case and boom, you've got yourself a basic e-ink laptop/writing device.
- A Keyboard Case for the PineNote would be amazing

Bluetooth keyboard via USB-C on remarkable 2
Hi, this is my first post in a looooong time at reddit, so hope you enjoy this idea. We have been discussing a lot here https://github.com/dps/remarkable-keywriter/issues/14, and it is possible providing an external power source

Rm2 As Typewriter
Following back up on this one, I've posted the hack allowing you to convert your rm2 into a typewriter [here](https://github.com/dps/remarkable-keywriter/issues/14).

C++23: The Next C++ Standard
I should have said the "latest standard", not "spec", if we're being technical. But EVERY bit of official material is very clear about asserting that C++23 is still a preview/in-progress, not a standard. Saying otherwise is, strictly speaking, incorrect.

Why is the token "designator brace-or-equal-initializer" not defined in the C++ 20 standard document?
I'm currently going through Annex A of C++20, but I can't find the definition of "designator brace-or-equal-initializer", and couldn't find much formal information on it in an obvious way. The newest source on [decl] (https://github.com/cplusplus/draft/blob/main/source/declarations.tex) also doesn't seem to have it. Am I missing anything, or is this a missing definition in the standard grammar?

Can sanitizers find the two bugs I wrote in C++?
> I don't have a copy of the standard at hand, can anyone quote the relevant section?
The C++ (draft) standard is on GitHub! [0] Compiling it needs Perl and some LaTeX packages, but is reasonably straightforwards otherwise. In addition, links to specific draft standards can be found on cppreference [1].
But anyways, in the first C++20 post-publication draft (N4868), the wording you're interested in is in multiple sections. Section 22.2.3 Sequence Containers [sequence.reqmts] has Table 78: Optional sequence container operations [tab:container.seq.opt] (starting on page 815), which states that a precondition of pop_back() is that empty() returns false. Section 16.3.2.4 Detailed Specifications [structure.specifications] (page 481) states:
> Preconditions: the conditions that the function assumes to hold whenever it is called; violation of any preconditions results in undefined behavior.
Therefore, calling pop_back() on an empty vector results in undefined behavior.
> Is this something that in practice is implemented in different (exception-throwing) ways?
Based on a quick glance at the major implementations (libc++ 15.0.7 at [2], MSVC at [3], libstdc++ at [4]), it looks like asserts are used. Whether those result in exceptions probably depends on whether the asserts are compiled in in the first place and how they are implemented, but it's definitely not a guaranteed exception.

How does Rust handle bounds checks that are incorrect in C/C++ due to signed integer conversion?
Which standard specifically are you quoting there? I checked an old and a new C++ draft in https://github.com/cplusplus/draft/tree/main/papers, and in neither one did 6.3 have anything like that.
