sgcl VS aplette

The SGCL repository contains the source code for this benchmark that uses the tracked pointers: https://github.com/pebal/sgcl/blob/main/examples/treap/treap...

You can look at the SGCL garbage collector for C++: https://github.com/pebal/sgcl. It works in a separate thread, is locks-free and never stops the world.

It will never be called gc_ptr because C++ programmers have an allergy to the term GC. However, an attempt was made to implement a similar solution. Take a look at tracked_ptr: https://github.com/pebal/sgcl

SGCL is a real-time garbage collector for C++ without any pauses.

Removed GC support was useless. You can have GC pointers in C++.

Mutators are threads that allocate memory and manipulate pointers, they can work completely independently of the GC. A mutator needs only to tag an object when copies or moves a pointer to this object. The GC detects this tag and marks the object as alive. Here is a working implementation for C++: https://github.com/pebal/sgcl

I don't know Rust but you can have a pauseless GC in C++. You just need to provide asynchronous access to root pointers.

There is Aplette which supposedly integrates nicely with other Unix tools. It's a port/update of the earlier openAPL source code, which I think was done by Ken Thompson? Here:

If you're interested in recent developments in array languages, I recommend checking out:

BQN https://mlochbaum.github.io/BQN/

ngn/k https://git.sr.ht/~ngn/k/tree/master/item/readme.txt (Previous discussion: https://news.ycombinator.com/item?id=22009241)

aplette, which is a modernization of Ken Thompson's APL https://github.com/gregfjohnson/aplette (Previous discussion: https://news.ycombinator.com/item?id=21740536)

I'd also recommend checking out J, which isn't a recent development, but has the best syntax out of all array languages, has the best development environments, is the easiest to learn (it has a way to learn it built into the language itself!), and is the only one that treats making GUIs as a first-class feature: jsoftware.com (Has so many previous discussions I just recommend using HN search to find them.)

The chat is biased to Dyalog APL, but a lot of the modern additions Dyalog has made to the language make it (in my opinion) worse as a notation, so ideally don't let it turn you off of the concept of array languages entirely if Dyalog doesn't "click" with you.

If you haven't already, you should also check out Notation as a Tool of Thought, a paper so good it won Iverson the Turing Award:
