speed of dd
by Tim
When I do something like:
dd if='fedora.iso' of=/dev/sdb status=progress
I only get around 6 megabytes per second on a USB 2 Sandisk Cruzer
Blade flashdrive (store bought, not fleabay) plugged directly into a
motherboard's USB 3 port - one that's not sharing its host with any
other ports in use.
Surely it should be going a lot faster?
When plugged in, dmesg shows this for the drive:

Configuring a Fedora 33 system as NAS
by Robert McBroom
After a painful experience of the lack of support of a Seagate Goflex
Home never updated from smb1, and finding the inadequacies of a WD
MyCloudUltra2, I'm ready to tackle configuring an older Dell system as
the NAS for my network. What do I need to configure besides NFS and smb
servers?

konqueror fails
by Michael Hennebry
I recently installed konqueror on F33 with gnome.
Gnome seems to not know of it.
The problem seems to be:
kf.service.services: The desktop entry file
"/usr/share/applications/org.gnome.ChromeGnomeShell.desktop" has Type="Application" but no Exec line
a message I get starting it from the command line.
There are other errors, e.g. QWaylandGLContext: failed to create EGLContext, error=3009
Eventually konqueror aborts.
ps a
includes
358792 tty3 Ssl+ 0:00 /usr/libexec/gdm-wayland-session /usr/bin/gnome-ses
so I infer I am running wayland.
How do I run konqueror?
I also have to run brasero from the command line, bit it works.

Can't burn a CentOS 7.9 DVD
by Robert G. (Doc) Savage
Is the CentOS-7-x86_64-DVD-2009.iso really too big to burn on a DVD-R?
Brasero under Centos 7.9 and Fedora 33 both say a 4.7GB blank disk
isn't big enough.

A question about Wine in fedora
by Francisco Tissera
Hello everyone,
I am having this problem where, when I try to launch a Windows
application with Wine, this happens.
Xlib: extension "NV-GLX" missing on display ":1".
Xlib: extension "NV-GLX" missing on display ":1".
MESA-INTEL: warning: Performance support disabled, consider sysctl
dev.i915.perf
_stream_paranoid=0
What is this? has anyone experienced this before? if so, how do I fix it?
Thank you for any answers.
Best regards.
Francisco.

dnf dkms interaction
by Robert McBroom
When updating the kernel, dnf tries to use dkms to add my NVIDIA
drivers, For some reason it tries to use 390.129 instead of the current
390.141 driver. The manual install works.

Is it looking for just one entry here? Perhaps the installer is not
cleaning the directory.
Thoughts?

Any Jython users out there? Please speak up!
by Miro Hrončok
Hello Fedora users.
I am one of the Fedora's Python maintainers.
One of the several Python implementations we have in Fedora is Jython:
https://www.jython.org/
It has just been removed from Fedora Rawhide (Fedora 35+) because nobody
volunteered to maintain it. I'd like to know if we have some users who will be
negatively impacted by Jython removal, so I can work with them to find a solution.
Being a Pythonista myself, I don't know any Jython users running Fedora. If you
use Jython on Fedora, please let me know how you install Jython: If it is from
the Fedora package or from elsewhere, e.g. trough maven or downloading the
installer from jython.org, or something entirely different.
Thanks,
--

what's the relationship between rubygem deps and gem installing
them?
by Robert P. J. Day
possibly off-topic as it likely applies to other linux distros, but
i'm diving into ruby and i'm well aware that if i install, say,
vagrant, it comes with a pile of rubygem dependencies:
Installing:
vagrant noarch 2.2.9-3.fc33 fedora 572 k
Installing dependencies:
bsdtar x86_64 3.5.1-1.fc33 updates 65 k
rubygem-childprocess noarch 1.0.1-6.fc33 fedora 60 k
rubygem-domain_name noarch 0.5.20190701-3.fc33 fedora 53 k
rubygem-erubis noarch 2.7.0-23.fc33 fedora 39 k
rubygem-ffi x86_64 1.12.1-3.fc33 fedora 106 k
rubygem-fog-libvirt noarch 0.7.0-3.fc33 fedora 33 k
... etc etc ...
fair enough, but is there any effect from personally installing any
of those ruby gems using "gem install"? if i install ruby gems as a
regular user, they get planted under ~/.gem/..., but i assume those
are not taken into account when i'm installing vagrant.
on the other hand, if i install (as root) a gem using "gem install"
under /usr/share/gems, will the install process take that into
account?
