his implementation does not save space which is fine because that was not his intent. to make a programming analogy, he turned spaghetti-code into structured code.
1) Today I learned that named cells exist in Excel.
2) Excel is great for technical and non-technical people. You can teach Excel even to 10-year-olds (I first used it when I was a student around that age).
3) 1,048,576 rows are more than enough for 99% of Excel use-cases.
4) Excel can connect to external data sources, like databases and APIs, which can perform heavier and more complex data operations, taking this responsibility away from the spreadsheet. SQL queries and procedure calls can be embedded inside Excel spreadsheets.
5) There are some Excel skills, like named cells and VBA functions, that most people don't know. It's a matter of sharing knowledge with them, so they can make better spreadsheets.
Apple products last longer, retain their value longer, and are supported longer than their peers virtually across the board.
AppleCare is extremely cheap and comprehensive. I have had one Apple product fail in at least fifteen years and it was replaced without hesitation. It’s been nearly a decade since I’ve had an iPhone screen crack from dropping, and that used to be a regular occurrence. And if I do, again, it’s covered under AppleCare.
There are many harsh criticisms to be leveled against the company. This is not one of them.
Of all the major phone and computer manufacturers Apple is the least guilty of planned obsolescence IMO. Their hardware lasts forever if you take good care of it. And they provide software updates for much longer than anyone else.
There's nothing wrong with planning for a certain device lifespan, provided it's long enough. But there's a bell curve here: it doesn't make sense to plan for 20 years of support if 99% of the devices are broken or replaced by their users by then.
Also, Apple repair prices are high, but not outrageous. There will always be someone claiming they can do it for less, but not many that will give the same guarantees Apple does.
> I have some notes on a semiconductor fabrication process with just sustainable inputs: Ethyl Lactate, Lignin-Vitrimer, Nitrogen, CO2, Laser-induced Graphene, A-CNT, PCLP Photo-cleavable Lignin Polymer, Hexyl Cellulose
Yeah, I was thinking of something like that. If there are fewer chemical components, recycling gets easier.
A biodegradable product out of biodegradable inputs would be great for computing
Before looking into Lignin I was looking at deoxidizing rGO reduced graphene oxide with hydrogen plasma.
I learned that the work functions of graphene and CNT are actually sufficiently different such that the graphene could be a substrate for CNT FET without the charge jumping out of the gate to the board. Salt apparently dissipates electric discharge about as well as silicon.
But a plasma process would probably have a lower yield rate unless there are masks, which are expensive to fab but maybe necessary to compete at production scale.
Monolithic chip fab is slower but the fabrication plant CapEx and OpEx are lower.

Some helpful prompts for a sustainablefactory agent skill:
Identify and redesign to eliminate production health hazards and environmental hazards
Find and compare sustainable alternatives, workarounds, substitutes for
Consider cellulose, graphene CNT and other carbon allotropes, CO2, nitrogen
