So, my 2009 MacBook Pro decided to slowly die … and after dithering for about 3 years over what to buy to replace it …. I chose a Google Pixelbook (i7 variant, 500Gb NVME disk etc) (via eBay).
Here are some findings …
- Installing Linux within the supported VM environment is straight forward (see docs) but it’s a 4.14 kernel with Debian Stretch. Given it’s using BTRFS I’d prefer a newer kernel (or at least the ability to choose what kernel the VM boots…)
- I can’t seem to find a way of getting a clipboard manager that works across all applications (so I can copy+paste multiple things between windows). I’ve been using ClipIt for years on my main desktop.
- Sharing files between the Linux environment and native ChromeOS is kind of annoying (go into the Files app, and drag/drop the file(s) around). The UI hints at there being shared folders, but I’m guessing they’ll be enabled in a future release.
- Sound from a Linux app doesn’t work (when running vlc within the Linux VM, there is no sound); apparently a known bug so I’ll hope it’ll get fixed soon.
- It’s fast. Especially browsing the web.
- It’s not burnt my lap yet (unlike the MBP)
- It’s possible to get sound to stutter from e.g. Play Music, if you’re doing a reasonable amount of I/O (like PHPStorm rebuilding it’s indexes)
- Installing PHPStorm (and other Linux apps) was fairly straight forward (either via apt or however I’d normally do it in Linux) and generally works fine …
- There’s no “right click” for the mouse pad; instead you do a double finger tap. You can ctrl+click or use a two finger tap.
- Tablet mode is great for Android Apps – I’ve tried a couple of toddler apps and they just worked fine.
- Not all Android apps work properly – e.g. using Authenticator Plus for 2FA auth codes – doesn’t seem to be able to sync with my Google Drive backup and when opening it, there are always two windows for some reason.
- Thankfully you can “right click” on the launcher tray and configure it to auto-hide and pin apps you use often.
I’m toying with the idea of replacing ChromeOS with a native Linux install; but I’ve not yet seen enough evidence to suggest that it’ll work well.
Hopefully the Campfire project will have a release soon …. Until then I’ll be watching https://www.reddit.com/r/pixelbook etc
I ended up needing to install hitch on a server recently, so the https:// traffic could be routed through Varnish (along with the existing ‘http’ stuff) for performance reasons.
The server only runs WordPress sites, so there are WordPress specific things in the Varnish configuration (vcl) file below.
Versions: Varnish 5.2, Hitch 1.4.4, Apache 2.4 and Debian Jessie.

I keep forgetting the syntax for these two things, so there’s a chance writing it here will help me remember.
Possibly of use/relevance for: elasticsearch or Debezium….

This might work to configure monit on Debian (Jessie) to monitor postsrsd.
check process postsrsd matching "/usr/sbin/postsrsd"
start program = "/etc/init.d/postsrsd start"
stop program = "/etc/init.d/postsrsd stop"
if failed host localhost port 10001 then restart
if failed host localhost port 10002 then restart

As I keep losing this….
Creating a .deb kernel package from a vanilla kernel.org kernel :
- wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.4.24.tar.xz
- tar -xf linux-4.4.24.tar.xz
- cd linux-4.4.24
- cp /boot/config-whatever .config
- Optionally: edit and set: CONFIG_DEBUG_INFO=n to stop the *dbg* package being generated
- make olddefconfig
- make deb-pkg -j6 LOCALVERSION=-dg1

So, one of my office servers was misbehaving – and random crashes finally tipped me over the edge.

Historically I’ve used $RANDOM as a random number source in bash — a bit like :
RAND=$(( $RANDOM % 10 ))
when I’ve needed a random number out of 0,1,2,3,4,5,6,7,8 and 9
one problem with this is that $RANDOM itself is populated between 0 and 32767 by the shell – so it’s not going to give totally even distribution.
Finally, I discovered ‘shuf’ — usage like :
shuf -i 1-100 -n 1
-n how many
RAND=$(( shuf -i 1-10 -n 1))
