You can't really divorce IPC from the process used, the amount of nested logic in each pipeline stage is a direct function of gate delay and therefore the manufacturing process. On one process I may be able to fit 10 stages while on a

Even on a transistors per mm measure the 14nm++++ they are using is vastly inferior to TSMC’s 7nm. Its only Intel 10nm that is equivalent and we don’t have desktop CPUs on that process yet (if we will at all).

It really shows you how good Intel's IP is that they can even make competitive CPUs on a generation old process.

At cruising speed the Concorde was as efficient as a commercial jetliner of the day. The issue was they had to be subsonic near land due to noise and in that mode of operation they were extremely inefficient.

You need division to go from a file offset in bytes to a sector number, hence the need for power of 2 sizes to make this fast. The kernel assumes in multiple places sectors are a power for 2 for this reason - it doesn't rely on the co

The issue is non power of 2 sector sizes. The kernel computes sectors with shifts not division (which would be slow).

I’m concerned this isn’t being done through the proper legal channels. The emergency powers act would allow the suspension of civil liberties and permit this. However short of that a mayor shouldn’t have this power.

Yes, I think we debated the whole concept of GDI being in the kernel as well. The Vista experience shows you it was and still is necessary for perf.

The simple answer is use D2D/Dwrite for low level render code in new projects. If you use C# there’s probably higher level wrappers over these. Some of the older C# APIs wrap GDI+ which is pretty slow and renders text really poorly so

You draw to a DirectX surface rather than the raw frame buffer but it is by no means translated to D2D. D2D has a "GDI" emulation mode, but it's more than worthless if you care about rendering fidelity with the real thing -

It was moved out in Vista with great fanfare. A side effect was GDI was no longer hardware accelerated. With windows 7 and later hardware acceleration was added back necessitating parts of it return to the kernel. For obvious reasons thi

Humans are social creatures. I find it hard to believe we'd accept indefinite "social distancing" over the long term - consequences be damned.

The thing I've learned dealing with professionals in other fields is that they just don't care as much as you do. The economics of their profession simply don't allow it. In software if you spend 8 hours fixing a bug that bu

You do lose the inherent value in the organization. Planes and humans don't create value on their own they have to be organized into a system. That system falls apart when a company is sold off for parts. Sometimes it makes sense if

Depends on where you work. My time at Microsoft was much closer to what you said I will not hear. There was a parable they used to use in training about how a young developer found a flaw that would only happen “one in a million” times - no

.NET has a very good inter-op story for win32. If you started with MFC, WPF, or another framework and then needed to add win32 flourishes you can do so quite easily. It's quite a different thing to try and retrofit a traditional win32

I don't think its fair to say it wasn't used. Just that it wasn't used on the big projects like Office. There were certainly a ton of internal tooling from that era that did indeed use it, which was also the primary use cas

TFS was never really that good and I won't defend it, but Winforms and WPF are more RAD tools not really appropriate to projects like Office. They are excellent for the tasks they were designed for. Re the Office libraries you probabl

It's so you can run software without trusting the operating system. And by extension that implies the root user as well, but that's not always the use case (it is for DRM). E.g. you might want your credit card processing in an en

The comment originating this discussion provides no evidence in any direction on the quality of the rust standard library. Merely that you wouldn't use these in practice, nor would you in C++.

The comment applies word for word to C++ as well. Linked lists are just bad datastructures for modern CPUs. I don’t use rust so I can’t speak to the quality of the std lib, but I don’t think its fair to use the parent comment as evidence ei

Sounds like the P series is a better fit for you. Hot swappable batteries, easy access to RAM and disk storage bays, and plenty of power for everything you want to do. I love mine to death, but it has that old school laptop weight and size.
