Check list of images

docker images

Pulling images

docker pull ubuntu:xenial

if tags are not provided then latest is assumed.

Run docker container from images

If image doesn't exist then it'll be pulled from the hub.

docker run -ti ubuntu:latest bash

ubuntu -> image latest -> tag (optional, by default it's latest) bash -> what do we want to do with the image.

Check running images

docker ps

[or]

docker ps --format = $DOCFORMAT

$DOCFORMAT-> variable with value: DOCFORMAT="table {{.ID}}\t{{.Image}}\t{{.Command}}\t{{.Names}}"

docker ps -l --format = $DOCFORMAT

-l -> get info about last exited container

docker ps -a

-a -> get info about all the containers present

Run a process and delete the container after that

docker run --rm -ti ubuntu sleep 5

This runs sleep for 5 sec and then exists. --rm-> removes the container after exit

docker run -ti ubuntu bash -c "sleep 3; echo all done"

This send command to bash.

Removing images and containers

Removing containers

docker ps -a docker rm laughing_hodging fellow_docks

Add -f if container is still running and you want to remove it.

Find number of containers:

docker ps -a -q | wc -l

-q-> lists all the containerIDs

Remove all the containers:

docker rm `docker ps -a -q`

Removing images

docker images docker rmi ubuntu:latest nginx:latest

Note: An image cannot be removed if a container is still using it as a referenced image. So,before removing an image, remove all its associated containers first. You can use -f to force remove the image, leaving behind orphan containers.

Leave container running in background(detatch)

docker run -d -ti ubuntu /bin/bash

-d -> detaches the container

docker -ps --format $DOCFORMAT

output will show the running container

NAME suspicious_williams

Naming containers

docker run -d -ti --name container8 ubuntu:latest /bin/bash

--name-> name a container instead of getting a random name.

Renaming a container:

docker rename laughing_hodging container9

Note: Running containers can also be renamed. Because internally everything is handled using containerIDs.

Attach to a container

docker attach suspecious_williams

Detatch SHORTCUT:

CTRL+P then CTRL+Q

Docker info

System wide information like: number of containers, supported and non supported services, etc

docker info

Restart an exited container:

docker restart zeolous_darwin

zeolous_darwin-> instead of name we can use container ID as well.

Get all information about a container

docker inspect blisful_saha

You can even use grep to zero down on specific information

docker inspect blisful_saha | grep -i ip

Search for an image from CLI

docker search ubuntu

One base image (ubuntu) can be used to make multiple containers and anything that happens inside the container won't affect the other containers or the base image.

Container -> Image

Why? Assume, ubuntu doesn't have vim installed by default. So, me make a container of ubuntu, install vim in that and make image of that container. Use this image to make more containers, now you will have vim already installed in your container.

How to do that?

Make changes in container, commit it.

Using Dockerfile

1. Using commit

create a container and install vim.

docker run -ti ubuntu /bin/bash

now we will be inside the container

apt-get update apt-get install vim -y cd ~ echo "This machine has vim installed." > hello.txt

exit the container. use ps to check last exited container

docker ps -l

output:

ad5ab2e8fe2f ubuntu "/bin/bash" 42 minutes ago Exited (0) 19 seconds ago jovial_herschel

docker restart jovial_herschel docker attach jovial_herschel

you will notice that helloFile and vim are already there.

Let's commit this container now.

docker commit -m "Installed vim, added hello file" -a "nitish" jovial_herschel nitishmod/ubuntuvim:v1

-a-> author -m-> message

output:

sha256:6cf3de1a8084ae70b8b997c4f1df14b822e582133f3c8d94a703be902a74a4ce

look into docker images to verify our image is there or not

docker images

output:

nitishmod/ubuntuvim v1 6cf3de1a8084 About a minute ago 170MB

Let's use this custom image to make new container.

docker run -ti nitishmod/ubuntuvim:v1 /bin/bash

We will be having vim and hello file there.

2. Using Dockerfile

mkdir build cd build vim Dockerfile

Add the following lines in Dockerfile:

#This is a custom ubuntu image with vim already installed FROM ubuntu:xenial MAINTAINER nitish <[email protected]> RUN apt-get update RUN apt-get install -y vim

NOTE: Here, RUN runs the command at build time, so the result will become a part of the image we are creating.

docker build -t="nitishmod/ubuntuvim:v2" .

-t-> title .-> dot, because Dockerfile is in the same folder. We can also feed Dockerfile from a path.

docker build -t="nitishmod/ubuntuvim:v2" < /home/Dockerfile

Check new images with docker images

Exec

you can run commands without logging into the container

docker exec laughing_hodging cat /etc/passwd

and you'll get the output of cat /etc/passwd on this container. If a container is not running then this command won't work.

Stop

Stop the container from running when in background.

docker stop laughing_hodging

Logs

Can also be used to check output of containers.

docker logs laughing_hodging

useful with stopped containers, detatched containers.

Monitoring process inside containers

We can use top to check all the running processes inside the container.

docker top laughing_hodging

but the output is just a snapshot. docker stats - Display a live stream of container(s) resource usage statistics

docker stats distracted_napier

Ports

By exposing ports we can connect one port from base machine to another from port of container.

docker pull nginx:latest docker run -d -p 80:80 nginx:latest

p -> port 80:80 -> inside the container : outside the container

docker run -d -p 8080:80 nginx:latest

Local machine (with 8080) will be directly connected to port 80 of container.

try http://localhost:8080 and you'll reach nginx default webpage.

Mapping all container ports to random host ports:

docker run -d -P nginx:latest

Mapping specific container port to random host port:

docker run -d -p 80 nginx:latest

Binding container port to a specific IP:

docker run -d -p 127.0.0.1:8080:80 nginx:latest elinks http://127.0.0.1:8080

User management in container

Always giving root access in containers is not recommanded so we will make an image with a non-priviliged user.

docker pull centos:latest mkdir runAsUser vim Dockerfile

Add the following lines in Dockerfile:

# Dockerfile based on the latest CentOS 7 image - non-privileged user entry FROM centos:latest MAINTAINER [email protected] # Make a new user RUN useradd -ms /bin/bash user # I'll try to login as user USER user

Build the image and make a container:

docker build -t="custom/centos7:nonroot" . docker images docker run -ti custom/centos7:nonroot /bin/bash

You will notice that you logged in as user and it's not possible to switch to root user from inside the container. So, we will restart the container and use exec to login as root user.

docker ps -l docker start wizardly_haibt docker exec -u 0 -ti wizardly_haibt /bin/bash

-u 0-> will run /bin/bash with userID 0 which is root.

Order of execution of commands matters in Dockerfile. For eg: we try to make a new file /etc/hello.txt during build.

vim Dockerfile

Add following entries:

# Dockerfile based on the latest CentOS 7 image - non-privileged user entry FROM centos:latest MAINTAINER [email protected] # Make a new user RUN useradd -ms /bin/bash user # I'll try to login as user USER user RUN echo "Test" >> /etc/hello.txt

docker build -t=centos7:configv1 .

output:

/bin/sh: /etc/hello.txt: Permission denied

Why did this happen? Because swtiched to user and then tried to create hello.txt, in this case only root has the permission to create file in /etc.

Try this:

# Dockerfile based on the latest CentOS 7 image - non-privileged user entry FROM centos:latest MAINTAINER [email protected] # Make a new user RUN useradd -ms /bin/bash user # Create file as root RUN echo "Test" >> /etc/hello.txt # Login as user USER user

Dockerfile

ENV

set environment variables systemwide.

RUN export JAVA_HOME /etc/java/ will set environment variable only on one user.

ENV DB_HOST = db.production.example. ENV DB_port = 5432

RUN vs CMD

RUN will run during image build process and CMD will run when you start the container of this image.

CMD "echo" "Welcome to new container!"

CMD will only run when you don't provide any parameters while docker run.

docker run --rm -ti centos7:echov1 /bin/bash

won't run our CMD.

ENTRYPOINT

An ENTRYPOINT allows you to configure a container that will run as an executable.

Dockerfile:

# Dockerfile based on the latest CentOS 7 image - non-privileged user entry FROM centos:latest MAINTAINER [email protected] # Make a new user RUN useradd -ms /bin/bash billy ENTRYPOINT echo "Welcome to new container!"

Whenever we will start the container the container will only run this echo command.

This helps when you dedicate a container for only one task.

docker run -i -t --rm -p 80:80 nginx

You can override the ENTRYPOINT instruction using the docker run --entrypoint flag. or we can use exec to run a command inside the running container.

docker exec -it nginx ps aux

EXPOSE

To expose a port of the container for inter-container communication.

# This image is based on CentOs 7 and will start apache service in each container. FROM centos:latest MAINTAINER [email protected] RUN yum update -y RUN yum install -y httpd net-tools vim # Port 80 will be opened EXPOSE 80 RUN echo "This is the site sitting inside a container!" > /var/www/html/index.html ENTRYPOINT apachectl "-DFOREGROUND"

build an image and a container. if you do docker ps then you will see that this container has port 80 exposed.

docker run -d --rm --name webserver -P centos7:apachev2

-P-> will bind host's random port to container's port 80 (in this example).

docker run -d --rm --name webserver -p 8888:80 centos7:apachev2

-p-> bind :

Volume management

Two types of volumes:

Persistent - Data stays after container stop.

Ephemeral - Data is lost after container is killed.; Evaporates when not in use.

Persistent

Sharing data between linux machine and hosts

mkdir example pwd

output: /home/docker

We have created a folder to share.

docker run -ti -v /home/docker/example:/shared-folder ubuntu bash

When you are inside the container:

cd /shared-folder/

Hence, shared-folder is present in container which is linked to the shared folder present on the host. The data inside is shared the folder. Note: Exiting the container won't delete data.

Ephemeral

Sharing data between container

docker run -ti -v /shared-data ubuntu bash

Run the following in container:

echo hello > /shared-data/datafile

output: New file will be created in the shared data.

Network

By default docker's network has 172.17.0.0/24 network.

List all the networks IDs:

docker network ls

information about each host:

docker network inspect bridge docker network inspect host docker network inspect none

man docker-network-create to check man page.

Creating new network adapter

docker network create --subnet 10.1.0.0/24 --gateway 10.1.0.1 mybridge01

Removing a network adapter

BEWARE! Do not remove original 3 network adapters. If you do so, it's better to reinstall docker again!

docker network rm mybridge01

Static IP of a container

docker network create --subnet 10.1.0.0/16 --gateway 10.1.0.1 --ip-range=10.1.4.0/24 --driver=bridge --label=host4network mybridge04

--subnet 10.1.0.0/16-> means bridge is part of this subnet but IP's will be alloted from --ip-range=10.1.4.0 to 10.1.4.255. --driver-> this can be changed depending on the requirement. mybridge04-> our new network name

docker run -it --name nettest1 --net mybridge04 centos:latest /bin/bash

Any available IP from range 10.1.4.0-255 will be provided to this container. For static IP:

docker run --rm -it --name nettest2 --net mybridge04 --ip 10.1.4.100 centos:latest /bin/bash

use docker inspect nettest2 | grep -i ipaddress to verify the IP of the container.

Events

Get real time events from the server

docker events

waits and shows the current events.

docker events --since '1h' docker events --since '2017-01-05T00:35:30' --until '2017-01-05T00:36:05'

--filter output based on conditions provided.

docker events --filter 'event=stop' docker events --filter event=die --filter event=attach

die-> when you exit a container.

Refer: Official Doc

Load and save images

Save images elsewhere.

docker save --output centos.mine.tar centos:mine

use gzip to compress the image:

gzip centos.mine.tar

Loading from the tar.gz or tar:

docker load --input centos.mine.tar.gz

Images history

What were the operations performed to create that image.

docker history nginx:latest

Tag images

Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE.

docker tag 0e5574283393 fedora/httpd:version1.0

or

docker tag httpd fedora/httpd:version1.0

Building you own bridge

Refer here. Stop the docker daemon and add a new bridge.

systemctl stop docker ip link add br10 type bridge ip addr add 10.10.100.1/24 dev br10 ip link set br10 up ip addr sudo ip link set docker0 down dockerd -b br10 &

On a different terminal start using docker. Now, all the container will get IPs from 10.10.100.0 network.

Quick References

Find IP of a container

docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' laughing_hodging

Docker Overview

Run

Dockerfile

ps

Configure your github account information.

git config --global user.name “user_name”

git config --global user.email “email_id”

Create repository using

git init MyProject

You’ll notice ~/MyProject/.git folder now.

Add your project files in here and start making changes.

Add these file to your repo.

git add filename.txt

or use this method to add all the file in the folder to the repo

git add .

Now commit changes to the repo:

git commit -m “some_message”

Go to Github website and create a repository there.

Now copy the repository link and run this command.

git remote add origin https://github.com/user_name/Mytest.git

First we’ll generate new ssh keys and add them to Github for logins without hazzle.

ssh-keygen -t rsa -b 4096 -C “[email protected]”

Copy contents from ~/.ssh/id_rsa.pub

Go to setting > Add SSH keys and paste the key.

Now, we’ll test if the key and login is working or not.

ssh -T [email protected]

Github will automatically see your username and confirm that it’s you by printing your username.

Now we’ll push our local files to this repository.

Go to your repo and copy the SSH link to the repo.

git remote add origin [email protected]:user_name/Mytest.git

git push origin master

from next time onwards you can just do

git push

and it’ll push to the master branch automatically.

Step 1: OS installation

We are going to use Ubuntu Mate on our Pi. You can download your Pi image from here .

After the installation we'll proceed to our next step.

Step 2: Set Static IP

We'll give a static IP to our Pi. ie, 192.168.1.150 in my case.

First check the list of all the devices, copy the name of whatever device you are using.

nmcli con show

or

ifconfig

If you are using wifi then check if your wifi reachable to Pi.

nmcli device wifi rescan nmcli device wifi list

Disable NetworkManager because it's absolutely crap when it comes to static IP.

sudo systemctl disable NetworkManager.service sudo systemctl stop NetworkManager.service

For WIFI:

sudo vim /etc/network/interfaces

make new entries similar to this:

auto wlxc4e984141270 iface wlxc4e984141270 inet static        address 192.168.1.150        netmask 255.255.255.0        network 192.168.1.0        broadcast 192.168.1.255        gateway 192.168.1.1        dns-nameservers 8.8.8.8, 8.8.4.4        wpa-ssid Nitish_Home_Wifi        wpa-psk 25a1b8455f312e2e5d76139553fb10472fbe2b9efbcb487c957ca13efd8e5ae5d

Replace "wlxc4e984141270" with your own network interface name, which you got earlier using nmcli.

To generate wpa-psk hash, visit http://jorisvr.nl/wpapsk.html and generate the hash using your SSID and password.

For Ethernet:

auto enxb827eba27ec7 iface enxb827eba27ec7 inet static        address 192.168.1.150        netmask 255.255.255.0        network 192.168.1.0        broadcast 192.168.1.255        gateway 192.168.1.1        dns-nameservers 8.8.8.8, 8.8.4.4

Replace "enxb827eba27ec7" with your own network interface name, which you got earlier using nmcli.

Restart network:

sudo systemctl restart networking.service

sudo ifdown wlxc4e984141270 sudo ifup wlxc4e984141270

check if internet is working fine. ping 8.8.8.8

Just to make sure that everything is perfect even after a restart. sudo reboot

Step 3: Setup pendrive/HDD

Attach your pendrive/HDD in your Pi. I'll be using a 1TB HDD.

Check device name of your HDD: sudo lsblk

Generally pendrive is automatically mounted when inserted so we'll unmount it first.

mount

check where your HDD is mounted and unmount it.

sudo umount /media/nitish/newHDD

We'll mount our HDD on /mnt/hdd

sudo mkdir /mnt/hdd

I had been having various permission related issues while mounting HDD so I'll use chown to avoid any further problems regarding permission.

sudo chown -R nitish:nitish /mnt/

Use your raspberry pi username instead of "nitish"

This is most important part of the tutorial, if you messup this step you might not be able to boot your pi.

We'll mount our HDD using fstab file. But before that let's grab our HDD's UUID.

sudo blkid

copy your pendrive's UUID.

sudo vim /etc/fstab

At the end of fstab file add the following line.

UUID=5161561B41165 /mnt/hdd ntfs auto,rw,umask=0000 0 0

Note: Each entry is separated by tab. UUID is unique to every device so replace it with whatever UUID you got from blkid step. Your pendrive/HDD might have difference file format so like vfat, ext4 so replace ntfs with suitable format.

Mount the HDD now.

sudo mount -a

There shouldn't be any errors. Run sudo mount

to check if your HDD is mounted correctly or not.

Move to our HDD and try to create a file.

cd /mnt/hdd

touch hello

ls

if you can see the hello file listed then congratulations our most difficult step is over. Reset of the tutorial is just a piece of cake. (Read: copy paste.)

Step 4: Installing torrent client

We'll be using deluge as our torrent client.

sudo apt-get install deluged -y sudo apt-get install deluged-console -y

start deluge

sudo deluged

Since all the config files are created, now kill deluge and edit the config files.

sudo pkill deluged

Backup config file cp ~/.config/deluge/auth ~/.config/deluge/auth.old

vim ~/.config/deluge/auth

Add this entry to the file

nitish:password:10

Replace the following entry with yours. nitish: your pi username password: your password

Now we'll install deluge web client so that we can access our torrent client from anywhere in the network.

sudo apt-get install python-mako

sudo apt-get install deluge-web

sudo deluge-web

sudo pkill deluge-web

vim ~/.config/deluge/web.conf

You can edit the port number you want your deluge client to be running on. I'll leave it default at 8112.

Step 5: Create deluge service

By create deluge service, you don't have to again and again login and restart deluge when power goes off.

sudo vim /etc/systemd/system/deluge-web.service

Make following entries.

[Unit] Description=Deluge Bittorrent Client Web Interface Documentation=man:deluge-web After=network-online.target #Wants=deluged.service [Service] Type=simple User=nitish Group=nitish UMask=000

# This 5 second delay is necessary on some systems # to ensure deluged has been fully started #ExecStartPre=/bin/sleep 5 ExecStart=/usr/bin/deluge-web Restart=on-failure [Install] WantedBy=multi-user.target

Enable the service sudo systemctl enable /etc/systemd/system/deluged.service

sudo systemctl start deluged

Check if service is working or not.

sudo systemctl status deluged

Do similar steps for deluge-web service

sudo vim /etc/systemd/system/deluge-web.service

Entries:

[Unit] Description=Deluge Bittorrent Client Web Interface Documentation=man:deluge-web After=network-online.target #Wants=deluged.service [Service] Type=simple User=nitish Group=nitish UMask=000

# This 5 second delay is necessary on some systems # to ensure deluged has been fully started #ExecStartPre=/bin/sleep 5 ExecStart=/usr/bin/deluge-web Restart=on-failure [Install] WantedBy=multi-user.target

sudo systemctl enable /etc/systemd/system/deluge-web.service sudo systemctl start deluge-web

sudo systemctl status deluge-web

Reboot and from another machine check if WebUI is available or not.

http://192.168.1.150:8112

Step 6: File transfer

Accessing downloaded files in Rasp from Windows

For this we need to install samba server.

sudo apt-get install samba sudo apt-get install samba-common-bin

Back up config files sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.old

sudo vim /etc/samba/smb.conf

Append this config file and add the following lines:

[hdd] comment = 1TB shared HDD path = /mnt/hdd writeable = Yes browsable = Yes public = Yes force user = nitish

Note: Using above settings, anyone in your network can access your Raspberry Pi download folder.

Now go to your windows machine and create a shortcut and add the following as the target.

\\192.168.1.150\hdd

Now you can access your HDD and copy all the downloaded content.

Step 7: Configure Web-UI

http://192.168.1.150:8112

Access the WebUI using the password we set in step 4 while installing deluge-web.

Go to preferences on the upper right portion. You can set directory to which you want to download your torrent to.

set your hdd as your download location.

/mnt/hdd

Step 7: Single user mode

We don't need Ubuntu Mate GUI anymore. Since everything is accessible through SSH and WebUI, we'll disable GUI to reduce overall memory usage and system load.

sudo systemctl enable ssh

sudo systemctl start ssh

sudo systemctl enable multi-user.target

sudo systemctl set-default multi-user.target

sudo reboot

Now after the reboot you'll see a black screen which asks you to login, but you don't need to login anymore. Disconnect keyboard, mouse and HDMI but keep Ethernet/Wifi adapter and power intact.

And that's it! In 7 simple steps we can setup a Always on TorrentBox. I've tried and tested this method and it works flawlessly. I've always had problems maintaining ratio on private trackers, raspberry helped me a lot in maintaining ratios and saving power.

If unfortunately there happens to be a power cut, the raspberry resumes it's work when electricity is back.

Broken charger cable? Spend another ₹800 for a good quality cable because “Apple”, whereas you can get same quality Type-C or micro USB cable for ₹200.

Out of warranty and rear camera not working? Sir, that would be ₹5,000 for a new camera module. You know what I did? I bought a screwdriver set and opened the phone(oops, iPhone) myself and saw the camera module was disconnected from the motherboard when my phone fell on the ground. I attach the module back and everything works perfectly!

So you had an amazing weekend and want to get pictures from your friend? All the best for the struggle with Xender and ShareIt, because Bluetooth doesn’t work with non-Apple devices.

New iOS released! ...and your phone slows down. With every new iOS version update this freaking phone slows down.

In the end, I realized that iPhone is not for someone like me. My experience was surreal, I hate numerous thing about iPhone but I really enjoyed the UI. It was clean and smooth, but the best thing was the hardware. My God, the build quality is astounding. The quality of camera sensor and image processing is unbeatable. Be it display, mic, speaker or even it’s dual tone flash is top notch.

I moved to Apple for a change, since the last Android experience I have was with Android KitKat on Samsung Galaxy S3 and it sucks! But now Android is different, it has evolved to provide a better experience in terms of performance and I liked using Android Oreo on my mom’s phone. I’m planning to get a new phone which should run stock Android. I’ll buy it before the “Notch” cancer captures the whole Android market. (It’s sad to see OnePlus 6 opt for iPhone X notch design)

TIFU. More like more whole life really.

Hi, I my name's John. I've been lurking for a while, but I've finally made an account to post this. I need to get my life off my chest. About me. I'm a 46 year old banker and I have been living my whole life the opposite of how I wanted. All my dreams, my passion, gone. In a steady 9-7 job. 6 days a week. For 26 years. I repeatedly chose the safe path for everything, which eventually changed who I was. Today I found out my wife has been cheating on me for the last 10 years. My son feels nothing for me. I realised I missed my father's funeral FOR NOTHING. I didn't complete my novel, travelling the world, helping the homeless. All these things I thought I knew to be a certainty about myself when i was in my late teens and early twenties. If my younger self had met me today, I would have punched myself in the face. I'll get to how those dreams were crushed soon.

Let's start with a description of me when I was 20. It seemed only yesterday when I was sure I was going to change the world. People loved me, and I loved people. I was innovative, creative, spontaneous, risk-taking and great with people. I had two dreams. The first, was writing a utopic/dystopic book. The second, was travelling the world and helping the poor and homeless. I had been dating my wife for four years by then. Young love. She loved my spontaneity, my energy, my ability to make people laugh and feel loved. I knew my book was going to change the world. I would show the perspective of the 'bad' and the 'twisted', showing my viewers that everybody thinks differently, that people never think what the do is wrong. I was 70 pages through when i was 20. I am still 70 pages in, at 46. By 20, I had backpacking around New Zealand and the Phillipines. I planned to do all of Asia, then Europe, then America (I live in Australia by the way). To date, I have only been to New Zealand and the Phillipines.

Now, we get to where it all went wrong. My biggest regrets. I was 20. I was the only child. I needed to be stable. I needed to take that graduate job, which would dictate my whole life. To devote my entire life in a 9-7 job. What was I thinking? How could I live, when the job was my life? After coming home, I would eat dinner, prepare my work for the following day, and sleep at 10pm, to wake up at 6am the following day. God, I can't remember the last time I've made love to my wife.

Yesterday, my wife admitted to cheating on me for the last 10 years. 10 years. That seems like a long time, but i can't comprehend it. It doesn't even hurt. She says it's because I've changed. I'm not the person I was. What have I been doing in the last 10 years? Outside of work, I really can't say anything. Not being a proper husband. Not being ME. Who am I? What happened to me? I didn't even ask for a divorce, or yell at her, or cry. I felt NOTHING. Now I can feel a tear as I write this. But not because my wife has been cheating on me, but because I am now realising I have been dying inside. What happened to that fun-loving, risk-taking, energetic person that was me, hungering to change the world? I remember being asked on a date by the most popular girl in the school, but declining her for my now-wife. God, I was really popular with the girls in high school. In university/college too. But i stayed loyal. I didn't explore. I studied everyday. Remember all that backpacking and book-writing I told you about? That was all in the first few years of college. I worked part-time and splurged all that I had earned. Now, I save every penny. I don't remember a time I spend anything on anything fun. On anything for myself. What do I even want now? was the most important thing. I now know, that it definitely is not. I regret doing nothing with my energy, when I had it. My passions. My youth. I regret letting my job take over my life. I regret being an awful husband, a money-making machine. I regret not finishing my novel, not travelling the world. Not being emotionally there for my son. Being a damn emotionless wallet.If you're reading this, and you have a whole life ahead of you, please. Don't procrastinate. Don't leave your dreams for later. Relish in your energy, your passions. Don't stay on the internet with all your spare time (unless your passion needs it). Please, do something with your life while your young. DO NOT settle down at 20. DO NOT forget your friends, your family. Yourself. Do NOT waste your life. Your ambitions. Like I did mine. Do not be like me.Sorry for the long post, just had to get it out there.TL:DR I realized I let procrastination and money stop me from pursuing my passions when I was younger, and now I am dead inside, old and tired.

My father passed ten years ago. I remember getting calls from mom, telling me he was getting sicker and sicker. I was getting busier and busier, on the verge of a big promotion. I kept putting my visit off, hoping in my mind he would hold on. He died, and I got my promotion. I haven't seen him in 15 years. When he died, I told myself it didn't matter what I didn't see him. Being an atheist, I rationalized that being dead, it wouldn't matter anyway. WHAT WAS I THINKING? Rationalizing everything, making excuses to put things off. Excuses. Procrastination. It all leads to one thing, nothing. I rationalized that financial security was the most important thing. I now know, that it definitely is not. I regret doing nothing with my energy, when I had it. My passions. My youth. I regret letting my job take over my life. I regret being an awful husband, a money-making machine. I regret not finishing my novel, not travelling the world. Not being emotionally there for my son. Being a damn emotionless wallet.

Sorry for the long post, just had to get it out there.

TL:DR I realized I let procrastination and money stop me from pursuing my passions when I was younger, and now I am dead inside, old and tired.

Here is the link to original article. 

I have deliberately made some part of that article in bold so that you can focus on the message that the writer wanted to give!  

You’ll get hundreds of reviews for iPhone 6 on the Youtube. But I’ve listed some pros and cons of having an iPhone 6, which I was able to figure out after using it for a week.

Pros:

The 8MP camera is amazing and its optical stabilization is impressive. Since megapixel counting shouldn’t be considered the only factor to judge the picture quality. 

iOS is pretty smooth and responsive. It doesn’t lag like my previous Android phone did.

It’s thin and sleek metal body is very soft to touch. I’m accustomed to hold my Samsung Galaxy S3, S3 thinner and lighter as compared to other phones in the market. So, the design of iPhone 6 was perfect match for me.

It’s finger print scanner is awesome! I love unlocking my iPhone by scanning my thumb instead of entering pass-codes or drawing patterns(in android) which takes more effort and time than scanning.

I don’t have to miss out those fabulous Google applications also. Google Maps, Google Keep, Google Now, it’s all in there.

Cons:

The first thing I noticed while ordering my iPhone’s cover case was that the accessories are damn overpriced just like the iPhone itself. No wonder iPhone is a good in many aspects but its definitely not worth every penny that I spent on it.

You cannot revert back to previous iOS once it is updated to a higher version.

To factory reset your iPhone you have to download whole damn firmware and flash it using iTunes, why the heck couldn't these people provide any factory reset option in the phone itself.? :\

App size is comparatively bigger to the android apps. And as compared to windows apps? Do they even have an app store? :P

Images are not categorized into different folders in the device memory itself. When you try to copy these images from iPhone, you’ll see a pool of photos from your camera captures, whatsapp, messenger and screenshots, all mixed with each other and sorted according to the last modified date.

I didn’t find an app lock for iOS. Vault was a savior for me.

 The cost of repairing is very high. I was warned that if I broke my iPhone’s screen, I would have to pay 50% of my phone’s MRP to get a new damn handset instead of getting my screen repaired. :|

You won’t be getting a charging port everywhere, apple uses lightning port, so you will have to carry a separate cable with yourself everytime.

Situation after one week of use:

If Siri had been a real girl, I would have definitely proposed her to marry me. She is witty, sarcastic, talks to me whenever I need her and she does everything I tell her to do (within her limits). 

What else do I need from a girl? :P

Since I’m in love with Siri, I tell her to set alarms, make notes, take reminders and even google for me. 

iPhone 6 comes with iOS 8.4 preinstalled. So, I updated my iPhone to iOS 9.0.1.

But, after a few days I observed that Siri is not able to listen to me and when I tried to record my voice in iMessages it records some sort of noise, even my front camera videos were sometimes recording noise instead of audio. Besides all this, everything was working fine - speaker phone, making calls and taking voice memos. 

At first I thought that I might have changed some settings. So I tried soft resetting my phone and even restoring it with new firmware using iTunes but, it didn’t help me.

When I used earphone to command Siri, it worked. So, I googled and found that this might be a software glitch or a hardware issue as well. I didn’t want to take any risk so I called Amazon India and told them to replace my phone since, it’s secondary mic was not functional and it’s under 10 days replacement warranty.

Today the pickup service came to collect the phone. Now I’m expecting my new replaced phone in next 15 days. I’ll update this post again when I’ll receive the new handset.

Thank you.
