Experimenting to create service without programming

As soon as zapier launch the new
multi step zap feature, I have this idea of creating service without actually doing any programming.

Here is the plan:
I try to follow event source architecture that is really suitable with zapier. Then it will be backed with Google spreadsheet to persist the events and data. I will also use some of excel function only if other approach is not possible. Typeform will provide a nice user interface to gather user input. And twilio will act as notification sender.

@iwan, I am going to use our varius use case :)

Reading output from running crontab process

— update–

for more ways to do it checkout http://askubuntu.com/questions/192798/reading-the-output-from-any-process-using-its-pid


Today I was run a long process from crontab. But I forget to set the output of the command. Checking with ps aux | grep command_name shows me the pid. After that I can do the following command to actually shows the stdout of the process. really cool right?

tail -f /proc//fd/1

ssh disconnect issue

On a normal day, I keep several console connected with ssh to my servers. Often, I encountered my ssh console frozen or

 Write failed: Broken pipe 

In order to avoid such issue, we can simply add these lines to ~/.ssh/config

Host *
ServerAliveInterval 60

Installing passenger on existing nginx

The normal installation of passenger usually require you to either do
1. passenger-install-nginx-module, or
2. go to nginx source and reinstall manually with extra –add-module /path-to-passenger-module

I am a bit reluctant to do option-1 because I already have some modules running with my nginx and option-2 is a bit troublesome because I install nginx with apt-get so I dont keep the source code.

Instead I found the official instruction which show me how to upgrade nginx installation in ubuntu.

sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 561F9B9CAC40B2F7
sudo apt-get install apt-transport-https

Create a file /etc/apt/sources.list.d/passenger.list and insert one of the following lines, depending on your distribution.

##### !!!! Only add ONE of these lines, not all of them !!!! #####
# Ubuntu 13.10
deb https://oss-binaries.phusionpassenger.com/apt/passenger saucy main
# Ubuntu 12.04
deb https://oss-binaries.phusionpassenger.com/apt/passenger precise main
# Ubuntu 10.04
deb https://oss-binaries.phusionpassenger.com/apt/passenger lucid main


sudo chown root: /etc/apt/sources.list.d/passenger.list
sudo chmod 600 /etc/apt/sources.list.d/passenger.list
sudo apt-get update
sudo apt-get install nginx-extras passenger

Edit /etc/nginx/nginx.conf and uncomment passenger_root and passenger_ruby.
sudo service nginx restart 

add config file to your site-available

server {
listen 80;
server_name example.com;
passenger_enabled on;
root /var/www/my_rails_app/public;

if you don’t have nodejs already, install it with this command:

sudo apt-get install nodejs
