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
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
# 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?
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
Thanks in advance,
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).
The version of sagemath that I run sagemath-8.0-2.fc28.x86_64, gives me
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?

Hi to all,
I'm new both in the ARM and Raspberri Pi world.
Managed to install Fedora 29 Server on a Raspberry Pi 3 Model B+ with an USB SSD.
The system works flawlessly but I can't find vcgencmd and relative commands to manage the hardware of the RPI.
Looked for an RPM package but I can't find nothing.
Is there a package with tools to manage HW? Temperature, CPU Frequency, and so on. Or is better to replace vcgencmd with something else?
Thanks in advance
I'm using shred on some 2Tb USB disk drive that I plan to give away.
So far it has taken 8 hours to shred 50% of the drive, which implies
that it will take about 16 hours to shred the whole drive. I have
another 2 drives to go.
Is there a quicker way to protect my data when I give the drives away,
other than smashing the drives to bits?
Thanks - jon
