PostgreSQL 12 released
Version 12 of the PostgreSQL database management system is out. "PostgreSQL 12 enhancements include notable improvements to query
performance, particularly over larger data sets, and overall space
utilization. This release provides application developers with new
capabilities such as SQL/JSON path expression support, optimizations for
how common table expression ('WITH') queries are executed, and generated
columns. The PostgreSQL community continues to support the extensibility
and robustness of PostgreSQL, with further additions to
internationalization, authentication, and providing easier ways to
administrate PostgreSQL. This release also introduces the pluggable
table storage interface, which allows developers to create their own
methods for storing data." | | 2:41p |

[$] Why printk() is so complicated (and how to fix it) The kernel's printk()function seems like it should be relatively simple; all it does is format a string and output it to the kernel logs. That simplicity hides a lot of underlying complexity, though, and that complexity is why kernel developers are still unhappy with printk() after 28 years. At the 2019 Linux Plumbers Conference, John Ogness explainedwhere the complexity in printk() comes from and what is being done to improve the situation. |
