    u-boot is infuriating

    Ok, a bit of fudging stuff around and I think I have this figured out. The Raspberry Pi 3 B+ has the magic boot bits set to boot from usb0, however, I haven't been able to get the OpenBSD bootloader to load a kernel from an FFS filesystem at the boot> prompt if I boot from usb0 (mmc0 loads just fine, however).

    So I dd'd the latest miniroot63.fs to an sd card, then disklabel'd the sd card and deleted the 'a' partition. I edited the sd card with fdisk and grew out the OpenBSD partition to the full remainder of the sd card after the msdos partition. Once that was done, I disklabel -dE'd the sd card and created an 'a' partition that took up the entire OpenBSD area. Once that was done, I dd'd the first 4 MB of the miniroot back to the sd card, ftp'd the bsd* files for arm64 to the sd0a partition, and booted the pi up with my franken-sd.

    Now at the boot> prompt I can select any of the bsd* files I copied to the sd0a partition, so I obviously select the bsd.rd file, install to my external SATA drive. I reboot, catch the ddb error about the duid it can't find (and copy that to a safe location), then boot back up to bsd.rd, disklabel -E sd0 and update the duid ('i'), edit /etc/fstab to use the new duid, and...

    Then I cross my fingers and reboot!


    NOTE: this approach basically disables any advantage you would get from kernel re-linking! And updating this franken-sd isn't going to be fun =\

    The little outlet that couldn't

    Yeah, once I figured that part out it was pretty clear why certain outlets failed when what seemed like an unrelated room had a power issue.

    My house is wired that way. The circuit breakers follow the construction of the house and not the rooms.

    15-year-old desktop kept alive with Debian 9 and Xfce (but not GNOME)

    Bumblebee display driver displaces Nouveau -- no crashes since

    To recap, after I upgraded my 15-year-old-desktop machine (Pogo2003) to Debian 9.4 from 8.10, I started having regular crashes, frequently but not always after resizing a window. I was running the Xfce desktop environment. I tried adding LXDE to see if the culprit was the DE. It wasn't -- the crashes continued under LXDE as well as Xfce.

    The latest thing I did was install the Bumblebee graphics display driver from the Debian repository. So far I have not had a crash since the Bumblebee install. Guess I'll give it a month or so before claiming problem solved, but I am optimistic.

    ExTiX 18.7 – “The Ultimate Linux System” – with LXQt 0.12.0, Refracta Tools, Calamares Installer and kernel 4.18.0-rc5-extix – Build 180723

    Softpedia 180724: ExTiX "The Ultimate Linux System" Now Uses Linux 4.18, Based on Ubuntu 18.04.1 LTS

    "Based on packages from the Ubuntu 18.04.1 LTS ("Bionic Beaver") and Debian GNU/Linux 9 "Stretch" operating system series, ExTiX 18.7 is the first release of the GNU/Linux distribution to use the forthcoming Linux 4.18 kernel series, which is currently in development and should hit the streets early next month.

    Arne Exton was brave enough to rebase his ExTiX Linux operating system on the fifth Release Candidate of Linux kernel 4.18, which is patched to allow the installation of Nvidia’s proprietary graphics drivers. Arne Exton's 4.18.0-rc5-extix kernel replaces kernel 4.16.2-exton used in the previous release, but it's an unstable kernel".

    ExTiX 18.7 is now on the front page at That will surely increase the download numbers. Dramatically.

    RaspAnd Oreo 8.1 for Raspberry Pi 3 Model B and Model B+ – Build 180717 – with Google Play Store, Aptoide TV and TeamViewer

    Softpedia 180717: You Can Now Install Android 8.1 Oreo on Your Raspberry Pi 3 Model B+ Computer

    "Just two weeks after releasing the first build of his RaspAnd operating system based on Google's Android 8.1 Oreo mobile OS, Arne Exton today announced a new version with support for the Raspberry Pi 3 Model B+ computer.

    RaspAnd Oreo 8.1 Build 180717 is basically identical with RaspAnd Oreo 8.1 Build 180707 except for the fact that it now also supports the latest Raspberry Pi 3 single-board computer, the Raspberry Pi 3 Model B+, which features a more powerful 1.4GHz 64-bit quad-core processor, dual-band Wi-Fi, Bluetooth LE 4.2, faster Ethernet, and Power-over-Ethernet support."

    There is more to sed(1) than s///

    As a followup, bradvan had asked about using sed to delete a block if it contains specific text.

    The following deletes all blocks of text that begin with 'aa' and end with 'cc' if they also happend to contain 'bb' somewhere in between:

    sed -e "/^$Begin/,/^$End/{H;\$!d;}; x;/bb/d;\${p;x;}" somefile.txt;
    This makes use of the hold buffer.
