Quote of the week

Make it work, then make it beautiful, then if you really, really have to, make it fast. 90 percent of the time, if you make it beautiful, it will already be fast. So really, just make it beautiful! -- Joe Armstrong


LLVM/Clang 16 💻

Yoe Distro uses Clang as default compiler; therefore it's interesting to see a new major release building up in 16.0.0 which branched last week, scheduled to be released in fist week of March. It has switched to using C++17 as default standard. This will require some porting for few packages, a notable change is for packages defining own alignof is flagged as undefined behavior. A way to fix it is to use _Alignof, it was also a problem in gnulib which is used by several downstream projects.


Simple IoT v0.8.0 release 🚀

This release adds system, app, and process metrics. See documentation for more details.



Go 1.20 release 🚀

A new errors.Join() function has been added to concatenate errors. You can later errors.Unwrap() to see the individual errors, or test for the presence of an error with errors.Is().

The go tool no longer relies on pre-compiled standard library package archives in the $GOROOT/pkg directory, and they are no longer shipped with the distribution, resulting in smaller downloads. Instead, packages in the standard library are built as needed and cached in the build cache, like other packages.

This is good -- the less we ship around pre-compiled binaries for tooling, the better. The requirement for pre-compiled binaries often leads to brittle tooling.

There are many other improvements -- read the release post!
