The variable arguments in
printf formatting means that it is easy to get type mismatches. The
practical results vary considerably:
printf(â0x%08lxâ, p); // Printing a pointer as an int â truncation or worse on 64-bit
printf(â%d, %fâ, f, i); // Swapping float and int â could print nonsense, or might actually work (!)
printf(â%s %dâ, i, s); // Swapping the order of string and int â will probably crash
[.] (aside: understanding why #2 often
prints the desired result is a good ABI puzzle)
I had to think about this for a bit, and then I realized why and
how it can work (and why similar integer versus float argument
Google asks Chromium developers to stop using Windows 7

Google has asked Chromium developers to stop using Windows 7 almost 11 months after Microsoft officially ended support for the operating system.
Google has asked Chromium developers to move to Windows 10, as reported by WindowsLatest.
“Windows 7 no longer works for building Chromium and nobody has volunteered to add support and Windows 7 is an unsupported OS; so this change formalises that Windows 10 is now required in order to build Chromium. This updates the documentation and modifies one of the build scripts so that a readable error message will be displayed when building on Windows 7 is attempted,” Google wrote in its Chromium resource page.

An Introduction to Lock-Free Programming
Lock-free programming is a challenge, not just because of the complexity of the task itself, but because of how difficult it can be to penetrate the subject in the first place.
I was fortunate in that my first introduction to lock-free (also known as lockless) programming was Bruce Dawson’s excellent and comprehensive white paper, Lockless Programming Considerations. And like many, I’ve had the occasion to put Bruce’s advice into practice developing and debugging lock-free code on platforms such as the Xbox 360.
Since then, a lot of good material has been written, ranging from abstract theory and proofs of correctness to practical examples and hardware details. I’ll leave a list of references in the footnotes. At times, the information in one source may appear orthogonal to other sources: For instance, some material assumes sequential consistency, and thus sidesteps the memory ordering issues which typically plague lock-free C/C++ c
