Did you know that the old deprecated GetTickCount actually returns 64-bit (not-overflowing) value, same as GetTickCount64, but computes the result differently?

Some `winver` am I right?

It was supposed to fit into 4 kB at first, but many nice-to-have features keep popping up. What should I add next?

IDK, I still want ADL for scoped enums in C++, i.e.:
enum class color {
red,
green,
blue,
};
int function (color c);
int main () {
function (red); // color::red
color green = blue; // color::blue
function (green); // locals have priority
}
Using-enum-declaration doesn't quite cut it.
enum class color {
red,
green,
blue,
};
int function (color c);
int main () {
function (red); // color::red
color green = blue; // color::blue
function (green); // locals have priority
}

The "backward compatibility" lying of Windows 11 is getting truly ridiculous.
GetThemeSysFont (TMT_CAPTIONFONT) now returns "Segoe UI" no matter how hard the app is manifested, despite it actually using "Segoe UI Variable" and both fonts having different symbols and fallbacks.

Hey mom, I'm coding clever things again:
template <class C, class R, class… Args>
R (* GetFn (R (C::*m) (Args…))) (void *, Args…) {
typedef R (C::* MemFn) (Args…);
typedef R (* RegFn) (void *, Args…);
constexpr auto x = sizeof (MemFn) - sizeof (RegFn);
...
template <class C, class R, class… Args>
R (* GetFn (R (C::*m) (Args…))) (void *, Args…) {
typedef R (C::* MemFn) (Args…);
typedef R (* RegFn) (void *, Args…);
constexpr auto x = sizeof (MemFn) - sizeof (RegFn);

This is the paragraph I was working on that required remembering the Amiga's clock speed. A 190,000 times speedup from 1985 to 2011 is pretty amazing, and that doesn't even include speedups from multi-core.

I thought about getting TLoU2 and competing in No Return, but the blatant cheaters (on PC) there totally dissuade me from that.

A few times a year I remember this short blog post. And the countless examples I could list, but won't.
The Sound of Silence
I recently heard one of the more interesting insights about Silicon Valley I'd heard in a while. It explained something I’d wondered about for years.
But I can't tell you what it was.
There's too...

Have to use Win11 for work and its so fucking great i love that every single function is worse than it used to be and every article is just an explanation of how to disable the new feature and make it a worse lobotomized Win10 its so good i might just fucking off myself i love it so much

I wrote a quick benchmark to measure the function call penalty from replacing pointer + size parameters with std::span (or string_view).
And the results are quite harrowing!
94 million calls per seconds vs. 355 M/s.
Must be a bug in the benchmark, right?

"Hyper-V Manager (virtmgmt.msc) is abandoned, use Windows Admin Center instead" – they say.
I tried: The latest version of WAC does exactly NOTHING more than than virtmgmt.msc. So why the fuck would I?

So I fixed Windows Update failing and rolling back.
By using massgrave scripts.
On my completely legitimate installation.
By some magic and googling I found that HRESULT of c004f011 in FACILITY_ITF reported by CMIADAPTER (in CBS.log) means licensing data broke...
