Linux container technologies are lightweight mechanisms for isolating running processes so that they are limited to interacting with only their designated resources.

Many application instances can be running in containers on a single host without visibility into each others' processes, files, network, and so on. Typically, each container provides a single service (often called a "micro-service"), such as a web server or a database, though containers can be used for arbitrary workloads. The Linux kernel has been incorporating capabilities for container technologies for years. More recently the Docker project has developed a convenient management interface for Linux containers on a host.

OpenShift Online is Red Hat’s application hosting platform that makes it easy for developers to quickly build, launch, and scale container-based web apps in a public cloud environment.

Mount an NFS Volume in Linux

# mount -t nfs nfs_volume local_dir options or # mount.nfs nfs_volume local_dir options for example: mount -t nfs /mnt/db2 If you have problem, you might need to mount nfs4 instead. mount -t nfs4 /mnt/db2 If permission denied, edit the /etc/exports file, for example /opt/docroot/,sync,no_root_squash) ⇒ range of networks NFS permits accesses rw ⇒ writable sync ⇒ synchronize no_root_squash ⇒ enable root privilege no_all_squash ⇒ enable users' authority $ sudo systemctl restart  nfs.service ( OR $ service nfs restart ) If you get the following error: mount.nfs: No such device Try adding the option:  -o nolock # mount -t nfs4 nfs_volume local_dir options  -o nolock See also: How to fix: mount: wrong fs type, bad option, bad superblock Also pay attention to your firewall setting. $ sudo -i firewall-cmd --add-service=nfs  --permanent success $ sudo -i firewall-cmd -

How to install/renew SSL Certificate for Glassfish

From certificate authority, you should generally receive two files Your signed certificate : generally named as “” Root certificate of your certificate (you might receive more than one. In some cases certification authority sends the intermediate certificates) : Godaddy names it “gd_bundle-g2-g1.crt” Next step is importing the keystore you used to generate the request into the Glassfish’s keystore: keytool -importkeystore -srckeystore /your-former-used-for-request/keystore.jks -destkeystore $GLASSFISHHOME/domains/yourdomain/config/keystore.jks Now, the final step done on keystore is importing the signed certificate. First, we gotta switch to Glassfish’s keystore and import the root certificate: cd $GLASSFISH_HOME/domains/yourdomain/config keytool -import -v -trustcacerts -alias root -file gd_bundle-g2-g1.crt -keystore keystore.jks -keypass changeit -storepass changeit Then, import the signed certificate of yours: keytool -import -v -trustcacerts -alias

Hypertargeting refers to the ability to deliver advertising content to specific interest-based segments in a network.

Hypertargeting is a marketing strategy where you clearly identify a target customer and deliver extremely relevant messages in the places where they will be most likely to see it. Segmentation : The act of dividing an audience into smaller groups based on their interactions with your brand or their demographics, sociographics, professional roles, values, goals, challenges, influences and buying habits. Retargeting : The act of sending messages to audiences who have already engaged with your brand. This could include remarketing to people who have visited your website, visited your store, made a purchase, followed your brand on social, signed up for an online opt-in offer, or had any other interaction with your brand.
