Focus on your data structures a.k.a. data tables. Those depend on your problem domain (the thing you are poking at with software). Then and only then, you may want to look at what is too slow on your particular CPU and OS. All the rest has

Not everybody was "purposefully" drowning themselves in boilerplate code in the first place.

Are cross-platform and native even mutually exclusive? You can have a C89 application that conditionally (#ifdef) compiles differently on MS Windows and Linux. It’s native. And it’s cross-platform.

Limits are a calculus/Geometry concept. A special case are Cauchy-sequences which model approximations. Domains (as I know the term) are more of a set theory idea. Not that that matters. Algebra also seems to be part of thinking well

What kind of math are you interested in? School-like math can be learned from text books, however, learning it with real people seems often more enjoyable. University style math, where you learn how to build/make mathematics and learn

That might depend on the problem domains you are working in. When I do standard CRUD in PHP, there isn’t much "math" involved. "Not even" clean category theory and/or powerful type systems. Some other applications

ASCII NUL terminated strings and double free don’t sound quite the same as gauging hardware requirements. Either you need a certain amount of memory or you don’t.

No. You seem to be thinking about computable functions. Not hardware dimensioning. It’s about resource usage on a finite physical computer. A Turing machine has a countably infinite tape.

SQLite3 just concatenation everything together into one compilation unit. So, more people have been using this than probably know about it. https://sqlite.org/amalgamation.html

Apologies for butting in. Programming language adjustments sound good on the surface but don’t really cut deep enough, as far as the problem domain is concerned. This is both research and implementation of a military grade solution. Think a

There was a Lenovo docking station compatible with the T420 (around 2012). The headphone Jack had shrieky noise on it whenever the Gigabit Ethernet connection got going. Took a while to figure that one out. The other two docking stations

Luckily you both missed the point. You missed this one here: "The data is most valuable when it is in the mainrack. Your Facebook data isn't nearly as useful without the ability to post to the pages of your friends. Your Google

It seems to be more about the data tables, data models and use cases, rather than the hardware. Maybe we can build a CSV file that only fits into a 19-inch rack. Someone would buy it for owning their own vendor-lockin story…

Well, in a rather simplistic world view the argument boils down to the following, which does seem to happen: (A) There are two dominating uses for large computers: (Use 1) HPC a.k.a. Floating point numbers, Fortran, LLM, CERN, NASA, GPGPU

Be wary of the bounds of your confidence intervals. Excel sheets got too large for my personal projections. Built a super simple static web app[1] as a replacement. It handles inflation better and provides a (very) simple monthly mortalit

You seem to have given this some thought. Honest question: What is your current estimate of how much the OOP side is impacted differently by Composition vs. Inheritance, especially when contrasted with FP?

Apologies for being slightly unclear. For both getting function composition and avoiding unnecessary intermediate allocations, the naive approach to using the SERIES package is insufficient. And the error messages it returns along the way a

Concerning stephen's item (2). The stricter set of rules was laid out by Richard C. Waters in Optimization of Series Expressions: Part I: User's Manual for the Series Macro Package, page 46 (document page 48). See reference Water
