Cello VS htop

Yes, that's C. C macros can take you quite far. Unfortunately because it's just a bunch of macros, it's quite brittle. Like high level abstractions created with macros in assembly language. You have to do all the checking and reasoning about it since the compiler cannot.

It took me a long time to understand, coming from higher level programming, that a lot of exactly that "higher level" is just systematic fat pointer conventions. And because pointers-with-metadata is not a first-class language construct, we invent all these languages that codify a particular fat pointer convention. Cello is an example of what kinds of abstractions can be built on top of a tiny little bit of (non-native) fat pointer convention.

There is a lightweight object oriented extension to C called Objective-C [1] that unfortunately never gained much traction outside the NeXT/Apple ecosystem. There is also Cello [2].

Regular expressions library to validate information before dumping to rocksdb.

Non-critical implimentation fun, use cello [1] for 'gawk' functionality in C with C++ objects/classes.

You can achieve a fairly decent runtime safety for some types of project. Check out libcello and my own monster (libstent, lame presentation).

towards lisp related data structures / algorithms (aka recursive tree data structures & algorithms).

So, no distinction between metadata vs. structual storage unless noted.

Anything beyond that tends towards masters & upper level undergraduate level material. aka review the implimentation of a programming language for algorithm & data structure usage per language features.

aka Autonoma / regular expressions backround: Lisp in Small Pieces by Christian Queinnec; ; https://github.com/aalhour/awesome-compilers; On Lisp by Paul Graham; Let over Lambda by Doug Hoyte; C 'macro's pushed to maximum effect : https://libcello.org/

    Left out Comparison of languages; Transform from lang a to lang b; and language implimentation as discussions tend to assume masters / upper level undergraduate knowledge

with skills like this, mind to push cello forward? https://github.com/orangeduck/Cello really like it but not skillful enough to do it myself.

Probably everyone knows about the "top" command. Htop is similar, but gives us a more user-friendly output. It shows processes using the most resources, how much available resources you have and who runs those processes. For more information, visit https://htop.dev/

determine which processes consume specific resources (in your particular case even a "5 minutes session of staring at htop" would do the trick.) (Alternatives: ps -ef, ps aux, top, glances ... )

When you see the laptop throttling, is htop or another monitoring program showing that the RAM is full, or is it only partly used?

I like htop to check system resources

try htop. It's already on Ubuntu, not sure about other flavors.

Program it in yourself: https://github.com/htop-dev/htop

htop is a colour-coded command-line system monitor, process viewer, and process manager. It shows a list of processes running on your computer ordered by CPU usage
