No Recursion Required

Fetching all the records from a multi page API endpoint without recursion back to the same function. Example in JavaScript.

const getAllProducts = async () => {
  // data and options is set elsewhere in this case
  data['maxRecords'] = 250;
  let res;
  let products = [];
  let page = 1;

  do {
    res = await, data, options);
    products = [...products,];
    count =;
    data['page'] = page + 1;
  } while (count === data['maxRecords'])

  return products;

OpenOffice Manual Install

  • Download deb .tar.gz file
    e.g: Apache_OpenOffice_4.1.7_Linux_x86-64_install-deb_en-GB.tar.gz
  • Extract it to a temporary directory
    tar xf Apache_OpenOffice_4.1.7_Linux_x86-64_install-deb_en-GB.tar.gz
  • Make a subdirectory to extract the deb files to and cd to it.
    mkdir tmp
    cd tmp
  • Run the following script to extract the contents of every deb file:
for file in find ../*.deb
   ar -xv "$file"
   tar xf data.tar.gz
   rm -f data.tar.gz control.tar.gz debian-binary
  • Move opt/openoffice4 to /opt/
    sudo mv ./opt/openoffice4 /opt/
  • Run /opt/openoffice4/program/soffice

You could now create a .desktop file and set its icon.

Solus Linux – Repo change

Swapping out the Solus repo from https to http so we can cache it in a local server.

$ eopkg lr

$ sudo eopkg ar solus
Repo solus added to system.

Speeding up freebsd-update

When using freebsd-update it can take a long time to complete. I’ve been looking at ways of speeding it up.

During the update process, it’s not uncommon for it to download 50,000+ files one at a time! Lets fix that.

The update below will run 8 copies of phttpget in parallel. xargs takes care of making sure each instance of phttpget has it’s own unique list of files.

# man xargs
-P maxprocs
      Parallel mode: run at most maxprocs invocations of
      utility at once.  If maxprocs is set to 0, xargs will             
      run as many processes as possible.
# ee /usr/sbin/freebsd-update

fetch_setup_verboselevel () {
         case ${VERBOSELEVEL} in
                 QUIETFLAG=" "
                 NDEBUG=" "
                 XARGST="-P 8" # UPDATED <<
                 XARGST="-P 8" # UPDATED <<


Solus Linux + OpenZFS

Solus is a great Linux distribution. Very clean and has everything I need, expect ZFS.

Building zfs is also discussed here:

NOTE: zfs-on-linux 0.8.3 and previous versions are NOT compatible with Linux kernel 5.5

You’ll need to install the development tools and some packages (Kernel modules are currently not building without libelf-devel)

Basic knowledge of how to use the terminal is assumed.

sudo eopkg install -c system.devel
sudo eopkg install git linux-current-headers libelf-devel

Lets build it. As of writing, the master branch is 0.8.0-rc2. I’m using –depth 1 so we don’t get the history or tags (optional).

Recommendation: Download the release archive and not the latest git source.

git clone --depth 1
cd zfs
make -s -j$(nproc)
sudo make install
sudo depmod

Or if you’ve just updated and a new kernel was installed (before rebooting) you can use (replace with correct path):

./configure --with-linux=/usr/src/linux-headers-4.20.8-110.current

While there is a script to load the kernel modules ( /usr/local/share/zfs/ ), there does not seem to be a service script that fires it up on boot.

Create /etc/modules-load.d/zfs.conf with your favorite editor and add the following:

options zfs zfs_autoimport_disable=0

Enable the services:

sudo systemctl enable zfs-import-cache.service
sudo systemctl enable zfs-import-scan.service
sudo systemctl enable
sudo systemctl enable zfs-mount.service
sudo systemctl enable zfs-share.service
sudo systemctl enable zfs-zed.service
sudo systemctl enable

Time to reboot and check everything worked.

lsmod | grep zfs

zfs 4087808 8
zlua 180224 1 zfs
icp 311296 1 zfs
zcommon 90112 1 zfs
znvpair 90112 2 zfs,zcommon
zunicode 335872 1 zfs
zavl 16384 1 zfs
spl 118784 5 zfs,icp,znvpair,zcommon,zavl


  • You will have to rebuild zfs every time the kernel is updated
  • If the kernel is updated your zfs pools will not mount on the next reboot – don’t mount any critical file systems which would prevent you from booting, onto a zfs pool.
  • It takes a little longer to boot since it scans for pools and mounts them

This tutorial was performed on a clean install of Solus Budgie 3.9999 after running eopkg up and rebooting.
