Ruby needs to be compiled with the--enable sharedoption. Dynamic linking to the Ruby library provides the best performance and best support. Static build support is incomplete for now. If using RBENV then the following is recommended: CONFIGURE_OPTS=--enable-shared rbenv install 2.7.1 ...
On one hand, this is great, because if we start polling a future and later decide we don't need its result anymore, we can stop polling it and we won't waste anymore CPU on doing useless work. On the other hand, this may not be so great if the future we're cancelling is ...

some explore ecosystems – whatever works best for them. Some even do all of that. People usually start by learning language features and ways to combine them in programs. At some point they learn different approaches to problem-solving. Sooner or later they move from using standard library com...
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions ...
