A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

It's not just the operating systems, it's also the way software is developed now. Those old windows applications were probably written in C++, which is only lightly abstracted over C, which is about as close as you're going to get to machine code without going into Assembly.
These days, you might have several layers of abstraction before you get to the assembly level. And those abstractions are probably also abstracted by third party libraries which might be chained to even more libraries, causing even more code to need to load and run. Then all of that might not ultimately even be machine code, it might be in a language like C# or Java where they're in an intermediate language that needs to be JIT compiled by a runtime, which also needs to be loaded and ran, before it can be executed. Then, that application might provide another layer of abstraction and run something in a browser-like instance, ala anything Electron based.
Are or were you able to compare it to SublimeText and UltraEdit by chance?
Good to know, because UltraEdit has been my goto editor for large files so far. Especially large "single line" files (length delimited data files for example). So I probably don't need to look for an alternative then.
Btw Sublime is cross platform. Even the license is cross platform. Buy once and use on every Windows, Linux and Mac machine you use. I find it much much snappier than VScode. But for large files it can't beat UE (and therefore emeditor). But for most editing tasks the UX beats the rest, IMO.
Have you tried Geany, by any chance? I recall it being pretty quick back in the days of single-core machines being the norm, but I'm curious how it stacks up now in terms of snappiness.
In dealing with large files or in general?
That's a good point. No abstraction is performance-neutral; they all have some scenarios where they perform fast and others where they are slow. We're witnessing the accumulation of hundreds of abstractions that may be poorly optimized or used for purposes outside of their optimal performance zones.
That's not true. Zero-cost abstractions are a key feature of C++ and Rust. For example, Rust
Option<&T>compiles down to nothing more than a potentially-null pointer.
