sensors command doesn’t show CPU temperature if you have Linux kernel 5.9.0-4. It is common problem of new hardware. But you can compile Linux kernel 5.10.0-rc6 where is the support for reading temperature in procesor AMD Ryzen 9 5900x.
I use simple script for screenshots (bind on PrtSrc key). It saves picture of current screens in home directory. Usualy I want open the picture immediately. I created simple script that opens the youngest .jpg file in current directory (named gimp-last).

bc <<< 5*4Yesterday I updated Windows 10, BIOS and some drivers of my Dell and couldn’t run Grub, just Windows Boot Manager. I re-installed Grub from Debian recovery without succes, Windows started directly after reboot.
First fix was copy /boot/efi/EFI/debian/grubx64.efi to /boot/efi/EFI/Microsoft/Boot/bootmgrfw.efi (with backup of original file, of course) and then Grub started. But why BIOS didn’t read /boot/efi/debian/grubx64.efi?
In BIOS (Boot Sequence menu) I had 1. option “debian” and File System List was “HD(1,GPT,D6E…)” what was wrong. I deleted this option and add new one with File System List “PciRoot(0x0)/Pci(0x17,0x0)/Sata(0x2,0x0)/HD(1,GPT,D6E…)” and correct File Name “\EFI\debian\grubx64.efi” and then Grub started work.
Then I reverted back “first fix”, rename back /boot/efi/EFI/Microsoft/Boot/bootmgrfw.efi.backup to /boot/efi/EFI/Microsoft/Boot/bootmgrfw.efi and Grub starts after reboot again.
All time when I used i3 window manager I used i3status too. i3status is little bar on bottom of the screen which displays info about things I’m interested in, i.e. free disk space, IP address, volume level, date and time (+ tray icons).

[device]
wifi.scan-rand-mac-address=no
[connection]
# ethernet.cloned-mac-address=permanent
wifi.cloned-mac-address=permanent[connection] section shouldn’t be necessary nor ethernet line (it is commented).
Tool to filtering e-mail. Can be installed via:
sudo apt install imapfilter
Example configuration in ~/.imapfilter/configu.lua:
local posvic_eu = IMAP {
server = 'mail.posvic.eu',
username = 'my@posvic.eu',
password = '',
ssl = 'ssl3',
}
local test = IMAP {
server = 'test.email.com',
username = 'my@email.com',
password = '',
ssl = 'ssl3',
}
function print_subjects(o)
for _, msg in ipairs(filter) do
mbox, uid = table.unpack(msg)
text = mbox[uid]:fetch_message()
print(string.match(text, 'Subject:[^\n]*'))
end
