The unique thing about estimates in software engineering is that if you do it right, projects should be impossible to estimate!
Tasks that are easiest to estimate are tasks that are predictable, and repetitive. If I ask you how long it'll take to add a new database field, and you've added a new database field 100s of times in the past and each time they take 1 day, your estimate for it is going to be very spot-on.
But in the software world, predictable and repetitive tasks are also the kinds of tasks that are most easily automated, which means the time it takes to perform those tasks should asymptotically approach 0.
But if the predictable tasks take 0 time, how long a project takes will be dominated by the novel, unpredictable parts.
That's why software estimates are very hard to do.
That's the point: how can you tell WHEN you are going to reach a place you've never been before traveling an uncertain path?
Making mistakes over and over again. And adding a lot of time buffers just to be safe

You don't need operand size prefix 0x66 when running 16 bit code in Real Mode. So "mov ax, 0" is 3 bytes and "xor ax, ax" is just 2 bytes.
My fault: I just compiled the instruction with an assembler instead of looking up the actual instruction from documentation.
It makes much more sense: resetting ax, and bc (xor ax,ax ; xor bx,bx) will be 4 octets, DWORD aligned, and a bit faster to fetch by the x86 than the 3-octet version I wrote before.
I remember a lot of code zeroing registrers, dating at least back from the IBM PC XT days (before the 80286).
If you decode the instruction, it makes sense to use XOR:
- mov ax, 0 - needs 4 bytes (66 b8 00 00) - xor ax,ax - needs 3 bytes (66 31 c0)
This extra byte in a machine with less than 1 Megabyte of memory did id matter.
In 386 processors it was also - mov eax,0 - needs 5 bytes (b8 00 00 00 00) - xor eax,eax - needs 2 bytes (31 c0)
Here Intel made the decision to use only 2 bytes. I bet this helps both the instruction decoder and (of course) saves more memory than the old 8086 instruction.

Every 3-4 years RAM prices spike.
There is always an excuse like a fire in a factory.
I believe the truth is 1) we have little amount of suppliers, and 2) supply is very near the limit of what can be sold.

As a designer, one should keep a couple of cheap, low-res monitors reset to the factory defaults for proofing what many users are going to see.
I must confess I felt a lot of lust looking at the self color calibration feature.
It is extremely useful if your work ends up in paper. For photography (edit: film and broadcast, too) would be great.
My use case are comics and illustration, so a self-color-correcting cintiq or tablet would be great for me.
Aside from lithography there's clever design. I don't think you can quantify that but it's not nothing.
Actually power efficiency was a side effect of having a straightforward design in the first ARM processor.
The BBC needed a cheap (but powerful) processor for the Acort computer and a RISC chip was
When ARM started testing their processor, they found out it draw very little power...
... the rest is history.

Not just reading, but drawing them.
For me nothing is better at inking than a Pentel Pocket brushpen.
I do some lino engraving from time to time as well.
Totally makes sense.
If you go to any mobile operafor you will see a lot of huawei hardware.
