Upgrade mutter to eliminate stutter in Gnome terminal on Ubuntu

Upgrade mutter to eliminate stutter

System impacted is a AMD workstation with NVIDIA graphics, running Gnome desktop on X11. The operating system is Ubuntu Desktop 22.04.4 LTS.

The latest mutter update causes stutter and lagging in Gnome terminal sessions. Switching to xterm relieves the problem, but not a real solution.

The problem was finally identified as a bug in the code to Canonical's latest update for Gnome's mutter window manager and compositor (Bug #2059847). A preliminary workaround PPA from mutter maintainer Daniel Van Vugt (vanvugt) stopped working after a new official update that retained the original bug. In a 15 May 2024 comment to the bug report (#135), Daniel posted links to corrected packages that fix the issue:

You don't really need to enable jammy-proposed. Just download the 3 proposed packages:

Effective Modern CMake

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

I will hate you

Dear C++ library writer,

  1. If your library forces me to use new all over, I will hate you.

  2. If your library has types with bogus values, I will hate you.

  3. If the documentation for your library gets the terminology of its own domain wrong, I will hate you.

  4. If I say "My God, it's full of stars!" when I see the function signatures in your library, I will hate you.

Latency numbers every programmer should know

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Validate input to a GtkEntry
/*!
* If you want to validate the text that a user enters into a GtkEntry widget

* The example below forces all characters to uppercase, and limits the range of
* characters to A-Z.\n
* Note that the entry is cast to an object of type GtkEditable, from which
* GtkEntry is derived.
