I'm using Ubuntu 16.04 LTS and I want to use the command line to send messages to my regular email account. There are administrative tasks that sends mail to root / administrator but to simplify my tasks I want these messages to be sent to my regular email account in Gmail. I installed postfix first. #apt install postfix mailutils Then accepted some basic configurations that were prompted when installing postfix.       General type of mail configuration?: Internet Site     System mail name: a hostname that will be used in mail headers, a FQDN is preferred, desktop, home     Root and postmaster mail recipient: root     Other destinations to accept mail for: $myhostname, desktop, localhost.localdomain, localhost     Force synchronous updates on mail queue?: No     Local networks: 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 192.168.0.0/24     Mailbox size limit:...

Hello Reese I am using the new Wave8 tablet from PLDTHome customer retention. It is fun to use a slightly larger screen. The brightness is different in IPS screens. I have to download the app for neutral brightness. The mail app is fine. The compose window have a bigger keyboard I agree with. No SMS though because this device is WiFi only. But it has android 6 marshmallow so it should be more secure than my zenfone android 5, right? It has 12 GB storage. It is a little cramped.

PLDT Home's customer retention bait is a device called the Wave8. This is a Android Marshmallow device. It has an IPS screen.

To find the UUID, use 'blkid' as root. This will generate a list of devices and their respective UUID's. Like so: #blkid /dev/mapper/sda5_crypt: UUID="DLkZz4-D3rH-dODr-eaO3-h1Oa-MLe2-9OVQMz" TYPE="LVM2_member" /dev/mapper/ubuntu--vg-root: UUID="d05b055d-032c-4f91-88d1-f8983d3474f6" TYPE="ext4" /dev/loop0: TYPE="squashfs" /dev/loop1: TYPE="squashfs" /dev/loop2: TYPE="squashfs" /dev/sda1: UUID="3f4ce798-b0c8-4c04-a83d-3628838cb6ca" TYPE="ext2" PARTUUID="68d8d639-01" /dev/sda5: UUID="a0497c16-a3ae-4610-820c-3bb61b52af1f" TYPE="crypto_LUKS" PARTUUID="68d8d639-05" /dev/sdb1: UUID="e3284314-1258-cac3-1b6c-243c748be2fe" UUID_SUB="f30caf8e-a9f4-672c-eb72-113d4520fc53" LABEL="desktop:0" TYPE="linux_raid_member" PARTUUID="8e34b25a-01" /dev/sdc1: UUID="e3284314-1258-cac3-1b6c-243c748b...

fstab is a file (actually /etc/fstab) showing the partitions that are automatically mounted by the kernel when it is booted. The kernel reads the fstab file and follows it. It is recommended that instead of a device name, a UUID is used. A UUID is a universally unique identifier for the device. This hexadecimal value doesn't change even as you remove hard drives or replace them, or move their connections around. In other words the hard drives don't get lost in the shuffle. If you have more than one hard drive in the box like me that would be a tremendous help keeping tabs. The fstab lists the root partition and swap partition. Ubuntu plans to use a swap file by Ubuntu 17.04 but fstab rules still applies. Each partition contains the name or UUID, mount point, filesystem type, mount options, etc. Don't worry about the details, fstab is automatically generated for you upon installation. You do get extra points for modifying it for security, and if you have mo...

I started my journey in Linux from Windows XP. I spent half the time trying to regain control of my computer. I spent too many minutes checking malware and viruses. I spent too many minutes wondering why my machine is getting slow. Then I ask myself if there's a better way. A better way is not a new GUI. A better way is not surrendering control to the machine and letting it handle the way I work. When I first install a Linux distribution, I was surprised at its speed, then I checked if I can work with the alternative applications. Using Linux is empowering. You figure things out with other people online asking the same questions. Then I read. Then I do and test. Then I learn. I don't create code. I do know how to work a script. I examine logs. Then I read. Then I learn. This is something I wouldn't do if I'm using Microsoft or OSX, although you can code on those platforms.
