SystemTap 3.0 released Version 3.0 of the SystemTap kernel tracing system has been released. Significant changes include an interactive script-building mechanism, a "monitor" mode allowing ongoing display of accumulated statistics, much faster associative arrays, function overloading, a lot of tapset improvements, and more. | | 8:09a |
Arch users: update pacman soon
The Arch Linux developers recently released version 5.0 of the pacman
package manager with some useful new features: "The release of
pacman-5.0 brought support for transactional hooks. These will allow us to
(e.g.) run font cache updates a single time during an update rather than
after each font package installation. This will both speed up the update
process, but also reduce packaging burden for the Developers and Trusted
Users." Unfortunately, once they start using these hooks, older
versions of pacman will no longer understand the resulting packages. That
will happen on April 23, so all Arch users need to have upgraded by
then. | | 4:39p |

Brinker: String Types in Rust Andrew Brinker looks
at string types in Rust. " Another important thing to note is that because the “owned” sorts of strings abstract away the underlying buffer, they can grow or shrink, possibly allocating a new underlying buffer and copying their contents to this new buffer. The “slice” sorts of strings cannot be resized, as they may not even be on the heap.
The “slice” sort strings can only be accessed via what’s called a “fat pointer.” This is because slices are “dynamically-sized types,” meaning they do not carry information about their own length. They are simply some collection of contiguous memory. A “fat pointer” to a slice stores both a pointer to the memory in question and the length of the data stored at that memory location. This is all handled automatically by Rust, but it means that the “slice” sort of strings are interacted with via references, rather than being handled directly." |
