Since I fixed my diet and got my testosterone back up to normal levels I'm having way less patience with oversensitive butthurt nerd's bullshit. Unfortunately they are the one's wielding banhammer.

I dared to criticize The Holy Reflections in C++ subreddit. Oh yeah.

Got myself quite a few ♥ for this. Apparently the sentiment is clear.

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 some magic and googling I found that HRESULT of c004f011 in FACILITY_ITF reported by CMIADAPTER (in CBS.log) means licensing data broke...

Hey Mom, my first improvement request for Chromium:
Do not keep the screens on if the user locks the workstation.
Arguably it's something Windows should be doing. The power requests should apply only when the relevant desktop is active, but it is what it is.

I've finally thrown together a new NAS.
11 drives, 58 TB total.
Alder Lake N100, 10GbE + 2×2.5GbE connectivity.
44 W in idle, 70 W when copying to/from one of the RAID 5. The 750W PSU was overkill, but hey, it has 92% efficiency.

It doesn't even attempt to get window's small icon, the WNDCLASSEX.hIconSm. Instead it searches Start shortcuts for that EXE, and extracts small icon from that.
So in order to have nice crisp small icon on the Taskbar, the app needs to have a Shortcut in Start menu.
