[$] Process tagging with ptags

By corbet For various reasons related to accounting and security, there is recurring
interest in having the kernel identify the container that holds any given
process. Attempts to implement that functionality tend to run into the
same roadblock, though: the kernel has no concept of what a “container” is,
and there is seemingly little desire to change that state of affairs. A
solution to this problem may exist in the form of a neglected
patch called “ptags”, which enables the attachment of arbitrary tags to
processes.

[$] Federation in social networks

By jake

Social networking is often approached by the free-software community with a
certain amount of suspicion—rightly so, since commercial social networks
almost always generate revenue by exploiting user data in one way or
another. While
attempts at a free-software approach to social networking have so far not met
widespread success, the new ActivityPub federation protocol and its
implementation in the free-software microblogging system Mastodon are gaining
popularity and already show some of the advantages of a community-driven
approach.

Nottingham: Internet protocols are changing

By corbet Worth a read: this
APNIC blog entry
from Mark Nottingham on the near-term evolution of
various Internet protocols. “The newest change on the horizon is DOH — DNS over HTTP. A significant amount of research has shown that networks commonly use DNS as a means of imposing policy (whether on behalf of the network operator or a greater authority).

Circumventing this kind of control with encryption has been discussed for a while, but it has a disadvantage (at least from some standpoints) — it is possible to discriminate it from other traffic; for example, by using its port number to block access.

DOH addresses that by piggybacking DNS traffic onto an existing HTTP connection, thereby removing any discriminators.”

[$] Toward better CPU load estimation

By corbet “Load tracking” refers to the kernel’s attempts to track how much load each
running process will put on the system’s CPUs. Good load tracking can
yield reasonable predictions about the near-future demands on the system;
those, in turn, can be used to optimize the placement of processes and the
selection of CPU-frequency parameters. Obviously, poor load tracking will
lead to less-than-optimal results. While achieving perfection in load tracking
seems unlikely for now, it appears that it is possible to to do better than
current kernels do. The utilization estimation
patch set
from Patrick Bellasi is the latest in a series of efforts to
make the scheduler’s load tracking work well with a wider variety of
workloads.

Elisa 0.0.80 Released

By ris A very early alpha version of the Elisa music player has been released.
Elisa allows to browse music by album, artist or all tracks. The music is indexed using either a private indexer or an indexer using Baloo. The private one can be configured to scan music on chosen paths. The Baloo one is much faster because Baloo is providing all needed data from its own database. You can build and play your own playlist.
