Try putting them in a zip archive or a 7zip archive.

I guess that they are trying to save space by making us compress stuff.

You can attach archives and images. Not sure what else.

Like I said, archives and images
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

let us assume the best software is those which makes best use of the transistors
given on a specific chip.

So let us compare the transistor count and the clock frequency of TCEC hardware:

Nvidia RTX 2080 TI:
18.6 billion transistors clocked with max 1.545 GHz
Nvidia RTX 2080:
13.6 billion transistors clocked with max 1.710 GHz

2*Intel Xeon E5-2699v4:
2*7.2 billion transistors clocked with max 3.6 GHz


Even with the best black magic bit twiddling hacks you will be limited by
transistor count and frequency, now do the maths and tell me where the
hardware advantage is...

Nvidia RTX 2080 TI: 250W
+
Nvidia RTX 2080: 215W
= 465W

Intel Xeon E5-2699v4: 145 W
+
Intel Xeon E5-2699v4: 145 W
= 290W
Watts are imo not appropriate for comparison, there are differences in
fabrication process for different architectures that causes different
consumptions...i am not that into fabs, but Nvidia RTX is produced in TSMC 12FFN
and the Xeons are produces in Intels 14 nm process...maybe Milos could clarify :)

14nm Intel vs 12nm TSMC
Transistor density (MTr/mm²) 37.5 vs 28.88
Transistor Gate Pitch (nm) 70-84 vs 88
Interconnect Pitch (nm) 52 vs 70
Transistor Fin Pitch (nm) 42 vs 45
Transistor Fin Height (nm) 42 vs 37
