Noodle respects requests for dark mode with the "prefers-color-scheme:dark" CSS that can be customized.

Web Browsers respect requests for dark mode by the Operating System, and can be customized:

  • Firefox:
    • about:config > ui.systemUsesDarkTheme=1
  • Firefox(Android):
    • Settings > Customize > Dark
  • Chrome(Desktop):
    • chrome://flags > "Force Dark Mode for Web Contents"
    • Note that as of v85 Chrome "prefers-color-scheme" is not supported, instead chrome will attempt to write it's own CSS for the page, often causing breakage (still true @ v105).
    • use chrome --force-dark-mode --enable-features=WebUIDarkMode to fix bug on Linux.

Operating Systems can be customized to use dark mode:

  • Windows:
    • Settings > Personalization > Colors > Choose your color > Dark
  • MacOS:
    • Apple > System Preferences, General, Appearance > Dark
  • Gnome(Linux):
    • Settings > Appearance > Dark
  • Android(Linux):
    • Settings > Display > Dark theme
  • iOS:
    • Settings > Display & Brightness > Dark

Other sites that support dark mode as of 2020:

Any user with access to system tools can reset the admin password with a web browser.

Any person with access to the SQL server can change the admin password to another users password

select object_id, username, password from users where username = 'admin' or username = '$ME';
update users set password = '$PASS' where object_id = '$ID';

For example

update users set password = 'P3b*cH.5fOBTJl5ELM)W' where username = 'admin';

The Business Continuity Plan for local installs is mostly up to the client and we provide a site export feature by which all data is converted to standard formats in a zip file to avoid vendor lock-in. We also have a HA option. and restoring from backups can be tested in a virtual machine.

Hosted instances have security measures in place and can be restored to any cloud or local environment. We maintain backup domains with multiple registries.

Example scripts for a High availability install of Noodle 7.08.05+.

1) Install 3+ Linux instances with password-less key authentication, run the following on each (using real IPs and domains);

hostname must match domain name.

IP1= #dn1
IP2= #dn2
IP3= #dn3
IP="$(ip addr show | grep "inet " | grep -v | head -n 1 | perl -pe 's/\/.*//g;s/.* //g')"

apt update
apt -y dist-upgrade
apt -y install ceph-fuse openjdk-11-jre
apt -y purge snapd landscape-common
apt -y autoremove

#if public domains are not in use;
echo "
$IP1 dn1 dn
$IP2 dn2 dn
$IP3 dn3 dn
" >> /etc/hosts

2) Install Ceph from the admin node (all nodes will wipe /dev/xvdb);

(Ubuntu 20.04 requires this patch first.)

apt-get -y install ceph-deploy

ceph-deploy new dn1 dn2 dn3
ceph-deploy install dn1 dn2 dn3
ceph-deploy mon create-initial
ceph-deploy admin dn1 dn2 dn3
ceph-deploy mgr create dn1 dn2 dn3
for N in dn1 dn2 dn3 ; do
        ceph-deploy osd create $N --data /dev/xvdb
ceph-deploy mds create dn1 dn2 dn3
for N in dn1 dn2 dn3 ; do
        ceph-deploy mon add $N
ceph osd pool create ${POOL}_data 16
ceph osd pool create ${POOL}_meta 16
ceph fs new ${POOL}_fs ${POOL}_meta ${POOL}_data
for N in dn1 dn2 dn3 ; do
	ssh $N "echo 'none /opt/Noodle/FSDB fuse.ceph,_netdev,defaults 0 0' >> /etc/fstab && mount -a"

3) Install CockroachDB on all nodes;

cd /opt
wget -qO- | tar  xvz
cp /opt/Noodle/cockroachdb.service /lib/systemd/system/
perl -pi -e "s/\$IPS/${IP1},${IP2},${IP3}/g;s/\$IP/${IP1}/g" /lib/systemd/system/cockroachdb.service
systemctl enable cockroachdb
systemctl start cockroachdb

4) initialize CockroachDB from the admin node;

./cockroach-v19.2.2.linux-amd64/cockroach init --insecure --host=${IP}
echo "CREATE USER noodleuser; CREATE DATABASE noodledb WITH ENCODING = 'UNICODE'; GRANT ALL ON DATABASE noodledb to noodleuser;" | ./cockroach-v19.2.2.linux-amd64/cockroach sql --insecure --host=${IP}:26257

5) Install Noodle on all nodes;

cd /opt
tar -xf Noodle.tar.gz
cd ./Noodle
echo "NoodleNodes[] = ${IP1}, ${IP2}, ${IP3}
FSDB = /opt/Noodle/FSDB" >> conf/
perl -pi -e 's/^(DatabaseManager.DB.intranet.Connection.Url = ).*/$1"jdbc:postgresql:\/\/'"$IP"':26257\/noodledb"/g' conf/
cp noodle.service /lib/systemd/system/
perl -pi -e 's/postgreql.service/ cockroachdb.service/g' /lib/systemd/system/noodle.service
systemctl enable noodle
systemctl start noodle

letsencrypt offers free HTTPS certificates with the limitation that you need to set them up to auto renew every ~3 months. Below are some example scripts that last of which should be called from cron.



. /opt/Noodle/
apt install -y certbot
systemctl disable certbot
mkdir $DIR
certbot register --agree-tos --no-eff-email -m "$EMAIL"
certbot certonly --webroot \
	--webroot-path $DIR \
	--cert-name "$DOMAIN" \
	-d "$DOMAIN"


systemctl restart noodle.service


. /opt/Noodle/
certbot renew --webroot \
	--webroot-path $DIR \
	--cert-name "$DOMAIN" \
	--deploy-hook /opt/Noodle/

Currently Noodle must be restarted to reload the keystore.
