See [1] and [2] for an overview of the versioning and naming schemes commonly used by shared objects libraries. `.0` is the major version of the library, and generally symlinks to the best minor version of that particular major release. The `.so` suffix, without any particular version number, is usually a symlink to the latest version installed, regardless of the major version. Consider the following hypothetical as an exemplar (can an exemplar also be a hypothetical ?). libfoo.so.0.2.5 libfoo.so.0 -> libfoo.so.0.2.5 libfoo.so -> libfoo.so.0.2.5 This reflects `libfoo` version 0.2.5, with zero as the major version and 2.5 as the minor. Now consider that a new major version of `libfoo` is released which breaks A.P.I.-compatibility with 0.2.5. The files now look like this, assuming v. 0.2.5 is still on the system: libfoo.so.0.2.5 libfoo.so.1.0.0 libfoo.so.0 -> libfoo.so.0.2.5 libfoo.so.1 -> libfoo.so.1.0.0 libfoo.so -> libfoo.so.1.0.0 This naming scheme allows application developers, such as those of `newsboat`, to assume that interface-breakages only occur on changes of the major versions, thus linking to `.so.` without having to care about the library's minor versioning. Unless you're the author of the library to which you're linking, or have some sort of assurance that your program won't be affected by potential library interface changes, it's probably a bad idea to link to the symlink with no specific major or minor version (libfoo.so). > any guideline that helps us figure out whether its > an app's fault or a lib's fault? In your particular case, `newsboat` is trying to link to `libstfl` major version zero, but unfortunately, the developers of `libstfl` have not included such a symlink, and instead expect developers to link to files providing a specific minor version. Technically, it is a problem of `newsboat`, however the authors of `libstfl` should follow proper versioning practice and provide a symlink for each major version. > My thirst for knowledge does not stop here. ;-) Read more about semantic versioning in the general sense at [3] and [4]. [4] is the Backus-Naur grammar, unneeded for a general understanding of the concepts unless you're implementing some sort of program to automatically parse or generate version numbers.

hi - could everyone share his rss reading setup? i have newsboat, but it got masked. so i'm now starting to look around again. i'm open minded and welling to question fundamentals in the theory of the optimality of rss feed readers. so if you have some principles/theories about what makes an rss feed optimum, please share these too, as it might help me think in a better way in my quest to find the best rss feed reader. summary of questions: - 1. what rss feed reader do you use? 2. what are your theoretical principles that guided you to choose the rss feed that you use. rgrds, cm.

Re: [gentoo-user] best rss reader?
Hi, I use liferea for many years now and I'm pretty happy. Doesn't sync to multiple machines though but I read RSS news only on my main laptop. I like how it's very straightforward and locally collects a configurable history of each feed and allows to structure them hierarchically into folders - however, many others offer similar features as well.

So I run MPD, gpg-agent, and syncthing continuously, while ctags and newsboat
are executed on a schedule via timers (a cron-like feature, see point 6 below),
hence their low-level activation state "dead".
Oh, and all units' output gets collected in the journal (see point 5 below),
which doesn't work with the alternatives (e.g., ~/.xprofile, which I used to
use).
4.) I use nspawn occasionally for running a Gentoo amd64 container for testing
asciidoc (I wound up proxy maintaining it). It's kind of a chroot on steroids,
hence you can use it in place of chroot, but you can also do things like run
containers as services (i.e., there's such a thing as an nspawn unit), but I
don't use that feature. Just as an example, the container I use is configured
like this:
% cat /etc/systemd/nspawn/gentoo-amd64-systemd.nspawn
[Files]
BindReadOnly=/home/marcec/projects/gentoo/:/home/marcec/gentoo/
BindReadOnly=/usr/portage/distfiles/:/usr/portage/ro_distfiles/
TemporaryFileSystem=/var/tmp/portage/
(I bet you never heard of ro_distfiles! I learned about it while setting up
the container (look up PORTAGE_RO_DISTDIRS in make.conf(5)).)
So this is pretty much like docker, which makes sense, since they use the same
underlying Linux kernel features. Systemd simply enables the treatment of
containers as services (including the ability to connect to a systemd instance
running inside a container, in the event that the container uses systemd as its
service manager).
5.) The journal is another element of systemd that one could write a lot about.
My usage is mostly limited to inspecting the state of a service ("systemctl
status " includes the last 10 lines of log output by default) and looking
for stuff in a specific time range. However, it has a few advantages over
classic syslog implementations:
- By default it captures all stdout and stderr of service units, so you can't
miss anything.
- It groups all log output of a service, regardless of how many processes it
consists of, i.e., you can't miss anything (I'm thinking of naive greps here).
- While you can just use grep (and I sometimes do), it's often better to use
the builtin search functionality, e.g., you can output journal entries
corresponding to a specific kernel device (not useful to me, personally, but
illustrates that there are a lot of filters you can use).
- As the prior point illustrates, journal entries consist of a *lot* of
metadata, whereas with syslog, you have a quasi-structured text file that
contains less information.
- It helps unclutter /var/log/ ;-) .
- Probably more that I can't think of right now.
If you don't care for it, you can also turn off persistent journal storage and
run a syslog daemon instead, or in parallel (you can't completely turn off the
journal, though, as it is still required for capturing stdout and stderr).
6.) I also happen to like timers a lot, because I can forego a cron daemon, and
I happen to like the "systemctl list-timers" output very much. But really, you
can just keep using cron, it's not a world shattering feature for me. It does
have the advantage of allowing dependencies to other units, though, since timer
units are units like anything else in systemd. This can be really powerful,
since, e.g., devices and mount points have corresponding unit types.
Actually, the main advantage of using timer units for me is that I can put them
in git and synchronise them across different computers, which I couldn't really
do with cron, because crontabs live somewhere in /var/ (right? Or was that only
the root crontab?). Also, since timers trigger service units, their output
goes to the journal, too.
7.) Use of ACLs. This is just a detail, but I like that my user looks like
this:
% id
uid=1000(marcec) gid=100(users)
Gruppen=100(users),10(wheel),35(games),1019(realtime)
