This week we’ve been making operating systems for the Raspberry Pi 4. We discuss our favourite gadgets, bring you a verrrry long command line love and round up all your wonderful feedback.

It’s Season 13 Episode 18 of the Ubuntu Podcast! Alan Pope, Mark Johnson and Martin Wimpress are connected and speaking to your brain.

In this week’s show:

lsblk -bdno NAME,SIZE | grep -v loop | while read dev size; do model=$(</sys/block/$dev/device/model); hours=$(sudo smartctl -a /dev/${dev} | awk '/Power_On_Hours/ { gsub(/h.*/, "", $10); print $10 }'); years=$(bc <<< "scale=2; $hours / 24 / 365.25"); size_tib=$(bc <<< "scale=4; $size / 1024 / 1024 / 1024 / 1024"); printf "%s %6d hours (%5.2f years) %.2fTiB %s\n" $dev $hours $years $size_tib "$model"; done | sort -rnk 2

sdd  50346 hours ( 5.74 years) 2.73TiB TOSHIBA DT01ACA3
sdc  50346 hours ( 5.74 years) 2.73TiB TOSHIBA DT01ACA3
sda  50345 hours ( 5.74 years) 2.73TiB TOSHIBA DT01ACA3

    Lidl is pronounced like ‘Lee-dl’.

  2. The time it says for my Intel SSD is funny.
    The WD1001 drive was bought back on May of 2010

    Kudos on making Ubuntu MATE 20.04 for the Raspberry Pi 4. I recently tried installed it and my sense is the performance seems snappier than some other (unnamed distros). However, I was disappointed that unlike these other distros, Ubuntu lacks two significant features:
    – booting from USB devices.
    – over-clocking via /boot/config.txt
    Are these features actually missing from Ubuntu MATE, or just some hidden way to configure them?
