Note Vi - Check if App is Running in Terminal

For example :
name of our application : myApp
location of our application : /home/binaryvi/Desktop/App

I try check app is running or not using terminal in ubuntu. I use shell script. Here we go:

#!/bin/bash

if ps aux | grep "[m]yApp" > /dev/null
then
   echo "Running"
else
  echo "Stopped"
  export DISPLAY=::0.0
fi


If app is stopped, i want run the app. This is the code:

#!/bin/bash

if ps aux | grep "[m]yApp" > /dev/null
then
   echo "Running"
else
  echo "Stopped"
  export DISPLAY=::0.0

  /home/binaryvi/Desktop/App/myApp&
fi

Note Vi - Edit Vim di Ubuntu

Jadi ceritanya tuh tadi nginstal library biar bisa kirim email via terminal di ubuntu 14.04, salah satu yang dioprek-oprek adalah 'sudo vim . . .'
setelah bisa masuk vim, tampilannya begini :

gbr 1.tampilan vim

berhubung ada yang salah, dengan senang hati vi hapus hapus hapus semua yang salah. terus ketik ketik ketik tapi oooh em jiiii kagak bisa #hwuuuaaaa..

setelah coba begini coba begitu kagak berhasil juga dan udah puas nangis kokosehan di dalam hati, tanpa salat istikoroh ahirnya vi memutuskan untuk menggunakan senjata pamungkas "nanya ke senior". ahihihihi

Ternyata biar bisa diedit,,, eng ing eeeeng setelah masuk ke vim, ketik huruf i. cuma gara-gara huruf i. Fiuuuh...

Trik-trik tambahan:

untuk keluar dari vim tanpa menyimpan hasil edit : 

1. ketik tombol escape (esc)
2. ketik q
3. ketik tanda !
4. enter

untuk keluar dari vim dan simpan hasil edit :

1. ketik tombol escape (esc)
2. ketik w
3. ketik q
4. ketik tanda !
5. enter

Jadi programmer itu, banyak kejadian dodol. But so challenging and fun banget.
Cap cis cuuus,, makasih udah mampir. Hope u have excited day ^_^

Note vi - Configure Postfix to Use Gmail SMTP on Ubuntu

This post 100% from https://rtcamp.com/tutorials/linux/ubuntu-postfix-gmail-smtp/ . It's my note, just for remember me.


If you want to use a Gmail account as a free SMTP server on your Ubuntu-Linux server, you will find this article useful. This guide is tested with Ubuntu 12.04. If you face any issue, feel free to use comments-section below.

Relaying Postfix mails via smtp.gmail.com:

First, install all necessary packages:

sudo apt-get install postfix mailutils libsasl2-2 ca-certificates libsasl2-modules

If you do not have postfix installed before, postfix configuration wizard will ask you some questions. Just select your server as Internet Site and for FQDN use something like mail.example.com

Then open your postfix config file:

vim /etc/postfix/main.cf

and following lines to it:

relayhost = [smtp.gmail.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_tls_CAfile = /etc/postfix/cacert.pem
smtp_use_tls = yes
You might have noticed that we haven’t specified our Gmail username and password in above lines. They will go into a different file. Open/Create

vim /etc/postfix/sasl_passwd

And add following line:

[smtp.gmail.com]:587    USERNAME@gmail.com:PASSWORD

If you want to use your Google App’s domain, please replace @gmail.com with your @domain.com

Fix permission and update postfix config to use sasl_passwd file:

sudo chmod 400 /etc/postfix/sasl_passwd
sudo postmap /etc/postfix/sasl_passwd

Next, validate certificates to avoid running into error. Just run following command:

cat /etc/ssl/certs/Thawte_Premium_Server_CA.pem | sudo tee -a /etc/postfix/cacert.pem

Finally, reload postfix config for changes to take effect:

sudo /etc/init.d/postfix reload
 
Testing
Check if mails are sent via Gmail SMTP server

If you have configured everything correctly, following command should generate a test mail from your server to your mailbox.

echo "Test mail from postfix" | mail -s "Test Postfix" you@example.com

To further verify, if mail sent from above command is actually sent via Gmail’s SMTP server, you can log into Gmail account USERNAME@gmail.com with PASSWORD and check “Sent Mail” folder in that Gmail account. By default, Gmail always keeps a copy of mail being sent through its web-interface as well as SMTP server. This logging is one strong reason that we often use Gmail when mail delivery is critical.

Once configured, all emails from your server will be sent via Gmail. This method will be useful if you have many sites on your server and want them all to send emails via Gmail’s SMTP server.

Alternatively, you can use a plugin like WP Mail SMTP so that mails from your particular WordPress site will be sent using Gmail’s SMTP server.

Please note that Gmail’s SMTP server has a limit of 500 emails per day. So use wisely! :-)

Troubleshooting

Error: “SASL authentication failed; server smtp.gmail.com”

You need to unlock the captcha by visiting this page https://www.google.com/accounts/DisplayUnlockCaptcha

You can run test again after unlocking captcha.
