Yoe 2022.02 was released with many interesting changes. It includes inclusive language changes across multiple layers especially in core and meta-openembedded and upgrades toolchain components to major new releases:
- Clang 14.0.0 release candidate
- Glibc 2.35
- Binutils 2.38
- GDB 11.2
- Go - 1.17.7
All layers are primarily using kirkstone (3.5) yocto project ready branches. This is first Yoe release of 2022!
QT company opensources
5.15.3 LTS release
after almost 2 years. The
meta-qt5 layer, which provides QT5 for
Yocto/Openembedded projects, is currently using 5.15.2 release. It would be
interesting to upgrade to 5.15.3 for Yoe Distro as well, since the
yoe-qt5-image reference image is based on QT5
Ongoing work continues in Simple IoT to support a duplicate node feature and better understand node lifecycle issues ADR-3. They are related as the duplicate features has the potential to create a large number of nodes quickly if the duplicated node has a lot of descendants.
The new Simple IoT documentation site has been deployed using mdBook -- it is working great! Will have more user documentation updates soon after the duplicate feature is finished.
Trying Julia in a Pluto notebook to run calculations for a circuit design. Initial impressions are positive -- seems to be well suited for the task. While reviewing the language, I've noted a number of interesting features of the language.
If you are looking for a simple personal/small business email server alternative to Postfix, check out Maddy. Maddy is a single binary mail server written Go that has support for all the standard stuff like SMTP, IMAP, TLS, DKIM, etc -- initial experiences are good.
