OSM & GPS??
by Beartooth
I have a pair of old Garmin RINO 120 GPSs and a gadget to connect
either of them, one at a time, to my PC, currently running F 29. For
several years I could run topo map software under WINE -- unfree software
from any, or almost any, of half a dozen vendors -- but never get any of
them to talk to either GPS. Now there is Open Street Map, a.k.a. OSM,
which I THINK runs natively under Linux.
I have studied forums and followed discussion lists (with Pan and
Gmane, since most of the content is obviously unrelated to my
questions). For years.
It seems that everyone else is a mapMAKER, and takes mere USE for
granted. I only want to use it, and only out in the woods or the desert
or the tooley weeds -- all of which, it seems, OSM does map, despite its
name. I want to get maps to scale that show things of interest to me
only, or I hope only -- things like good lunch rocks, and nests, and
particular trees, all or nearly all off any trail.
Unlike the OSM regulars, I have no advanced skills in
cartography, nor EE, nor CS. My skills and knowledge are in unrelated
areas.
All this boils down to two questions. If I install OSM under
Fedora, will it accept, incorporate, and display off-road and off-trail
data from an old GPS, either with OSM's own data, or with things like USGS
topo maps? And if it will, can an ordinary mortal learn to use it?

libvirtd, pihole, dnsmasq complaints
by Chris Murphy
I think this is just noise in the journal; not a real problem (it's an
annoyance).
Fedora Server 29 running two docker containers: pihole and battery
historian. When I do 'sysmtectl start libvirtd' I immediately start
getting the following in the journal every 5s.
Feb 11 13:53:23 fnuc.local dnsmasq[32033]: failed to create listening
socket for 192.168.122.1: Address already in use
That continues until I both stop libvirtd and also remove the virbr0
link. I'm kinda wondering if this is suboptimal behavior that
constitutes a bug? I don't know why it's failing to create a socket
for 192.168.122.1, maybe docker owns it. But then why doesn't libvirtd
just fallback to some other address and notify in the journal, rather
than spamming the journal? In any case I'm still able to ssh into and
out of any VM I create. I'm also able to connect via virt-manager and
spice to any VM. So its seems like it's just noise and not an actual
problem.

Very slow DNF update and a workabound
by Barry Scott
I'll been putting up with very slow dnf update for a while.
strace showed that it was reading /var/lib/rpm/Packages 4KiB at a time.
My /var/lib/rpm/Packages is 118MiB so that takes a while on a hard disk
around 60s.
My desktop is i7 4GHz CPU 16GiB of ram.
Unless there is a way to configure DNF to use bigger reads this hack speeds it
up.
# cat /var/lib/rpm/* > /dev/null; dnf update --refresh
After the cat of the files Packages will be in kernel buffers and then dnf
runs in 1s-2s.
Do you want a bug report on this issue?

VirtualBox shared folder looses connection after a while
by Paul Smith
Dear All,
With the most recent versions of VirtualBox, the shared folder is not
working properly as before.
My guest machine is running Windows 7, and the shared folder works
fine during some time. However, after some time, the connection to the
shared folder gets lost. Are other people experiencing the same? Any
workaround?
Thanks in advance,
Paul

more systemd brilliance
by Tom Horsley
Sometime recently systemd has decided to shutdown
the network interfaces before it unmounts all the
NFS filesystems, thus resulting in about a 5 minute
timeout on reboot.
I've now added code to my pre-reboot script to
umount -l and umount -f every nfs filesystem
prior to really rebooting, and I can reboot without
the 5 minute delay now (sheesh).

sagemath
by Patrick Dupre
Hello,
The version of sagemath that I run sagemath-8.0-2.fc28.x86_64, gives me
an error:
Oops, Sage crashed. We do our best to make it stable, but..
Should I try to compile the version 8.5 for my fedora 28?
Thank.

on screen keyboard?
by ToddAndMargo
Hi All,
Anyone have a favorite on screen keyboard that will operate
under Xfce?
I have been using Florence, but it seems to not be supported
anymore and crashes a lot.
Many thanks,
