system default installed packages Workstation
by Anil Felipe Duggirala
hello,
Could someone tell me, if I wanted to know, which are all the python
packages (modules) that come installed by default in Fedora 32
Workstation, how would I be able to get that list?
thank you,

Re: Flatpak?

Sounds like a trick question.
The answer is Flatpak.

Fail2ban-all
by Scott van Looy
I’m running F32
Trying to update today and I get:
Problem: cannot install the best update candidate for package fail2ban-all-0.11.1-6.fc32.noarch
- nothing provides python2-inotify needed by fail2ban-all-0.11.1-9.fc32.noarch
Anyone have any ideas if this is something I’ve done or if there’s a bug for this?

coloured text distorted on 4k monitor
by Eyal Lebedinsky
I recently started using a 4k TV as a monitor. The video is natively 4k from the on-board Intel i7.
I noticed that I often get difficult to read text. This is even worse when I use reverse video (black bg).
Looking closer I can see that the image changes as I shift the window one pixel sideways. Seems that
I get a different image when the left margin is odd and when it is even.
I run a test:
============================
#!/bin/sh
show_color() {
x="$1"
fg="-fg $2"
eval xterm $fg $bg -geometry $geo+$((x+0))+$((y+0*dy)) $cmd &
eval xterm $fg $bg -geometry $geo+$((x+1))+$((y+1*dy)) $cmd &
eval xterm $fg $bg -geometry $geo+$((x+2))+$((y+2*dy)) $cmd &
eval xterm $fg $bg -geometry $geo+$((x+3))+$((y+3*dy)) $cmd &
}
bg='-bg black'
cmd="-e 'ls /bin/z* ; read x'"
geo='70x10'
y='200'
dy='160'
off=500
show_color $((off+0)) "rgb:ff/00/00"
show_color $((off+450)) "rgb:00/ff/00"
show_color $((off+900)) "rgb:00/00/ff"
============================
Each column is one color (r, g, b) and each row is shifted one pixel.
Examining the windows with xmag shows clean text without any artifacts.
I am not sure of the policies regarding attachments on this list, I added four small images
of a closeups of some test screens. Two are green and two are blue. Each pair is shifted one pixel
relative to its mate. The blue one is worse.
===
Images are now here:

http://members.iinet.net.au/~eyaleb/attachments/20200801/dsc08807.jpg
===
Plain white text on black bg and plain black text of white bg is clean. Coloured text is problematic.
Does anyone have an idea where I can look?
TIA

I need help with "nmcli device status"
by ToddAndMargo
Hi All,
I am trying to use the nmcli command to cough up
(a highly technical term) the connected state on
a particular network interface.
According to the man page:
nmcli device {status | show | set | connect | reapply
| modify | disconnect | delete | monitor |
wifi | lldp} [ARGUMENTS...]
...
status
Print status of devices.
This is the default action if no command is
specified to nmcli device.
So here goes without the device:
$ nmcli device status
DEVICE TYPE STATE CONNECTION
br0 bridge connected System br0
virbr0 bridge connected virbr0
eno2 ethernet connected eno2
eno1 ethernet unavailable --
lo loopback unmanaged --
virbr0-nic tun unmanaged --
So far so good.
Now the specify as "specified" device:
$ nmcli device status eno2
Error: invalid extra argument 'eno2'.
Okay, what am I doing wrong/misreading?
Yes, I know I can use grep and awk. I will be
using Raku though:
$ nmcli device status | raku -ne 'for $_.lines -> $I
{ if $I.contains( "connected" & "eno2" )
{ say "connected"; last }}'
connected
Many thanks,

aarch64 mock gcc/annobin errors
by Sam Varshavchik
I'm running an F32 aarch64 guest qemu VM on an x86_64 F32 host, and, in that
VM, I attempted to build something fairly simple via mock. This is my reward:

First time I've seen something like that, any idea what to do here, for this?
This if from a first build in mock, which presumably pulled in the most
recent versions of all rpms into the chroot.

Fedora Zoom? -
by Bob Goodwin
I have a request from the VA to do a video interview rather than the
usual secure text messages.
"Do you have the ability to do a video appointment (you would need a
computer with a camera or a tablet or a smartphone)."
We have iPhones etc. that might work but my daughter suggests that I
need 'Zoom' on my Fedora 32 computer since I have trouble with the
smaller mobile devices. Is there a Linux equivalent application I can
run from my desktop workstation?

Interactive desktop latency
by Christopher Anderson
I am using FC32 on a AMD 3970X with HT off.
I have a program which maps a System V shm segment using huge pages, then references random locations for 10 seconds to find what the latency of memory is.
The funny thing is, the latency is better when printing to a terminal (xterm) under Xwayland, and worse when redirecting to a file or piping through less:
$ test -m sysv2m:shm.test -c 8 -p 100 -x int -o find -n 10
ival tot op/s ns
10.1 510000000 50605422 19.8
$ test -m sysv2m:shm.test -c 8 -p 100 -x int -o find -n 10 | less
ival tot op/s ns
10.1 350000000 34621166 28.9
The difference printing to stdout is significant, but it only happens under XWayland in a terminal, not on the console. The above use 8 MB shm of 2M page size.
I've looked at the CPU frequency, different nice priorities, tried different cpupower governors, I can't explain this weirdness. This does not occur under CentOS 8, even when using the same binary compiled under FC32.
When I use the prefetch instruction, prefetching the next 2 references, a command line option, the performance difference disappears:
$ test -m sysv2m:shm.test -c 8 -p 100 -x int -o find -n 10 -f 2
ival tot op/s ns
10.2 550000000 54143996 18.5
$ test -m sysv2m:shm.test -c 8 -p 100 -x int -o find -n 10 -f 2 | less
ival tot op/s ns
10.1 550000000 54260358 18.4

pgadmin3 in Fedora 32 Workstation
by Anil Felipe Duggirala
hello,
I have 2 separate questions regarding pgadmin installation in Fedora 32.
1. pgadminIII, I believe only supports postgresql up to version 11.x.
The default version (fedora repo) of postgresql is 12.3. So the pgadmin3
(pgadmin4 is not available) package in the default repository is not
compatible with the default postgresql package. Is this correct?
2. A couple of days ago, my terminal prompt changed from
"username@machinename", to "username@localhost". Did this maybe happen
after installing postgresql and/or pgadmin? Could anyone point me in the
direction of the documentation that explains how this all (domains,
setting them in Fedora, implications, etc.) works?
thank you very much,
Anil
