[$] printk() indexing When kernel developers want to communicate something about the state of a running kernel, they tend to use printk(); that results in a log entry that is intended — with varying success — to be human-readable. As it happens, though, the consumers of that information are often not human; the kernel's log output is also read by automated monitoring systems that are looking for problems. The result is an impedance mismatch that often ends with the monitoring system missing important messages. The printk()
format indexing patch set is the latest of many attempts to improve this situation. | | 3:53p |
Reports from the 2021 Python Language Summit Over on the Python Software Foundation blog, the reports from day 1 of the Python Language Summit are available. At the time of this writing, a few from day 2 are ready as well. There are lots of interesting topics discussed at the summit, including a talk on making CPython faster from Python creator Guido van Rossum. " Seven months ago, Guido van Rossum left a brief retirement to work at Microsoft. He was given the freedom to pick a project and decided to work on making CPython faster. Microsoft will be funding a small team consisting of Guido van Rossum, Mark Shannon, Eric Snow, and possibly others. [...] The team is optimistic about doubling CPython's speed for 3.11. They plan to try an adaptive, specializing byte code interpreter, which is a bit like the existing inline cache and a bit like the shadow byte code covered in Dino Viehland's talk." Some of the ideas go back to Shannon's thoughts on speeding up the interpreter that we looked at back in December. |
