Parade du Grotesque

Go to packages.slackware.com or slackbuilds.org and you will see the base system has reasonably up to date packages.

I have no idea what you are talking about. NetBSD is portable. Its performance is very good (it has to be, since it works on stuff like 68040 Amiga and Atari), but probably a bit under FreeBSD, since FreeBSD is mainly focused on Intel and AMD.

Slackware.

It. Just. Works.

I have used all 3 major BSDs (Free, Open and Net). FreeBSD is ideal for servers due to its performance. OpenBSD is perfect for security appliances and NetBSD is perfect if you have exotic legacy hardware.

This being said, I have also used OpenBSD for about two years as my daily driver on an old second hand laptop, and I really liked it. With a minimum of configuration, installing software was as easy as Debian (just your pkg_add), and configuration is just super easy since the OpenBSD documentation.

It has improved a lot done then: installing security updates (sysupdate) and upgrading (sysupgrade) from one version to the next is amazingly simple. If your hardware is supported, OpenBSD is just a pleasure to use. Its only default is the lack of “advanced” file systems and volume managers.

OwnCloud and Yunohost are the two that comes to mind. I will let you Google them.

I have Osmand+ and it works fine. One very easy way to improve the performance is to download the maps you need ahead of time.

Start by downloading your metro area and I can guarantee that positioning and navigation will be instantaneous. Unless your phone is to blame. FYI I am using a Google Nexus 7a. Very happy with Osmand+.

We are talking about programming, studying, surfing the web and average computer usage. OpenBSD is more than enough for all that.

OpenBSD.

Period.

Sure, you can harden Linux to the same level of security. But OpenBSD comes with all the goodies installed out of the box.

Liferea does the job and worries pretty well.
