In C (as opposed to C++) the explicit cast from void* to int* is not required. It is also not idiomatic to do so in C code.
Actual C codebase would use `malloc()` without the cast, and a C++ one (when not using abstractions) a `new int[n]` - both a bit cleaner and less verbose than this example.
Clarify that each philosopher should think/eat 100 times.
Folks who have hazy memories of the philosopher dining problem may
interpret the original instructions as "make each philosopher think and
eat once". This interpretation loses a critical detail, because the
resulting code is highly unlikely to deadlock in practice, even without
breaking the symmetry.
* Suggest to run day 3 afternoon exercise locally
Based on feedback from running the class, students found developing
the day 3 afternoon exercise locally was a better experience than
using Playground.
* Update src/exercises/day-3/afternoon.md

* Run builds on both Mac OS and Linux
This would have helped us catch #570.
* Fix MacOS CI (#848)
* Revert unnecessary changes
The changes might be good, but I want to keep this PR small and
focused. If we end up with the extra `cfg` statements, we should
include a comment to let students know what they do: we’re targeting
people new to Rust, so we need to be careful with explanations.

* Add page about entry point before Rust code.
* Convert tabs to spaces.
mdbook doesn't seem to handle tabs in code properly.
* Add page about handling exceptions.
* More nuanced discussion of Rust Raspberry Pi OS tutorial.
* Add note about EL1 to entry point page too.
The link worked fine when GitHub was rendering it — it rewrites the relative path correctly. However, when viewed as the output of `mdbook`, the link pointed to nowhere.
* Mention cancellation via select!
* Add a section on async cancellation
* Update cancellation slide, rework example
* Rework select! note about cancellation
* Collapse cancellation comparision to panic and ?
* Don't keep null bytes from incomplete reads
These translations all have more than 200 translated messages and
they’ve been updated in the last month.
I suggest we update the list here every few weeks based on input from
the translators: we don’t need a super strict rule here, we just need
interested translators who would like to see their work celebrated.
I suggest we only link completed translations in the language picker
since we have limited space there to differentiate the different
levels of completeness.
* Update build_all.sh
The path, $ANDROID_BUILD_TOP and/or $ANDROID_PRODUCT_OUT, can contain spaces, which results in error. As long as shell var is not number, it is safe to enclose it with ""
* Enclose full shell word in quotes
This is just a stylistic choice: I find it easier to parse a command line if the full shell word is in quotes.

Moving the sentence to the third point and requesting an example of `self` vs `mut self`.
* Update src/methods/receiver.md
Improved the tone of the sentence.

Normally developers are aware of the simpler language of implicit vs explicit. By replacing elided with implicit readability of the application might be improved.
Update unbounded.md to address inconsistent code
Fix inconsistency between concurrency `unbounded.md` and `bounded.md` by using implicitly named arguments for both.
