user crontab
by Robert Moskowitz
I know I can edit the user crontab with:
crontab -e
and display it with
crontab -l
But where is it? I don't see anything like ~/.crontab
Secondly, and more importantly, is getting a email from the user
crontab. I have in my crontab:
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=rgm
And nothing gets mailed to /var/spool/mail/rgm
ls /var/spool/mail/ -ls
total 0
0 -rw-rw----. 1 rgm mail 0 May 5 17:21 rgm
0 -rw-rw----. 1 rpc mail 0 May 5 17:07 rpc
Do I need something like postfix with a minimal installation to get the
output from my crontab?
thanks

I noticed that sendmail and mailx are not installed with the basic
workstation. Is there another MTA installed?

Fwd: Using cgroups v2 for “simple” tasks
by virgo
The struggle is real… Sorry, again.
The original message:
=-=-=-=-=-=-=-=-=-=-=-=
Greetings,
This machine is running under Fedora 32 Workstation Edition which means that,
among other things, cgroups are under a unified hierarchy.
$ sdver=(`systemctl --version | tail -1`)
$ for i in "${sdver[@]}"; do printf "%s\n" "$i"; done | grep "hierarchy"
default-hierarchy=unified
Before the upgrade, I was using Fedora 30 and libcgroup v1, leveraging with
that the libcgroup-tools to run some processes under certain constraints.
Since the upgrade, my scripts broke. Here is an example:
```bash
## libcgroup v1
# Configuring a group
TGT='foo'
GRP='woe'
let M=(500 * 1024 * 1024)
let C=250000
cgcreate -a "${TGT}:${TGT}" -t "${TGT}:${TGT}" -g memory:"$GRP" -g cpu:"$GRP"
printf "%d" "$M" > /sys/fs/cgroup/memory/"$GRP"/memory.limit_in_bytes
printf "%d" "$C" > /sys/fs/cgroup/cpu/"$GRP"/cpu.cfs_quota_us
# Using the new group
cgexec --sticky -g "memory,cpu:${GRP}" <SOME-COMMAND>
```
That does not cut it anymore. I tried to follow the manual and it led me to
write something like the file below.
# </etc/cgconfig.conf>
group woe {
perm {
task {
uid = foo;
gid = foo;
}
}
memory {
memory.high = 524288000;
}
cpu {
cpu.max = 0500000 1000000;
}
}
My limited understanding of the documentation left me with the impression
systemd would create the cgroup `foo` after a reboot. That, of course, turned
out to be false, I would not be here otherwise.
So, here is where your help would be greatly appreciated: how to use the
cgcreate command and the like under libcgroup v2? Alternatively, if the way is
by configuration files, where to create them and how to enforce what they
stipulate?
Thanks in advance.

Apologies for the duplicated message, but the one I sent earlier seems to have
missed the target: it does not appear in the archives. Maybe I should have
subscribed to the list before sending it…

How do you Dual boot with Intel RST - Optane ?
by sean darcy
My new laptop has Windows 10 installed with the Intel
rapid Storage Technology (optane) system chip. Windows is on an nvme
drive.
FC31 is on a SATA ssd.
BIOS allows me to choose AHCI or RST. I must use AHCI to boot the FC31
drive, and RST to boot the Windows drive. Neither will boot with the
other. Sigh.
1. Is there a way to get the FC31 drive to boot with RST ?
2. Any way to have the Windows drive boot with AHCI ?

Power Mgmt problem
by Christopher Marlow
I am having a problem with Fedora 32...... When my screen blanks off.
When I come back to the computer the screen will flash on for a sec and
then go black again. But the power light is still green...
And the only way I can get a picture back is to turn the monitor off
and hold a key down on the keyboard and turn the monitor back on at the
same time
its getting worse and worse
I had the same problem in 31 right there at the end
right before I upgraded to 32) --
~~~~~~~~~~~~~~~~~~~~
Thanks,
Chris

What process rolls the log files Saturday night?
by Robert Moskowitz
I see that my various log files have been rolled over at midnight.
But looking at the old and new cron, I can't see anything other than the
hourly anacron running and not seemingly doing anything...
So what did this? Not complaining it happened, just trying to track
things down.

Calc to excel -
by Bob Goodwin
Is there a fedora scheme for making an LibreOffice calc file acceptable
to excel in my daughter's Mac computer. Cal produces .ods and from what
I have found excel wants xls or xslx according to goole? I see some web
sites that claim to do the conversion on line, not really what I want to do.
