A post on Hackaday shows an interactive map of the Linux kernel that has been created by Costa Shulyupin. The map shows the structure of the kernel and includes over 400 prominent functions, each of which is a link to a cross-reference site for further information. The kernel is divided into 7 rows and 7 columns, with domains such as security, debugging, block devices, and address families. The map also includes arrows to show the relationships between different functions.

This interactive map of the Linux kernel is a valuable resource for those interested in understanding the structure and functionality of the kernel. It provides a visual representation of the major levels of abstraction and includes links to definitions and usages of specific functions. By exploring the map, users can gain a deeper understanding of how the kernel operates and how different functions are interconnected. This knowledge can help in troubleshooting, optimizing performance, and developing software that interact with the kernel. Additionally, the map serves as a gateway to further learning, allowing users to delve into specific domains and terms related to the Linux kernel.

WilliamLam.com reports that the latest version of the Synology NFS VAAI Plug-In (2.0-1109) can be successfully installed and used on an ESXi 8.0 system, despite Synology’s official support only going up to vSphere 7.0. The plug-in can be downloaded from the Synology website and installed using ESXCLI or vSphere Lifecycle Manager. After rebooting the ESXi host, a new shared volume can be created on the Synology using File Station and connected to the NFS v3 datastore. The new NFS VMkernel binding feature in vSphere 8.0 Update 1 can be used with the NFS datastore, and hardware acceleration is enabled. Performance with NFS is more consistent than using iSCSI.

This news is of interest to home lab enthusiasts who use Synology storage in conjunction with VMware vSphere. The ability to use the Synology NFS VAAI Plug-In on an ESXi 8.0 system provides improved performance and simplifies the configuration and management of storage.
