For this blog, i’ve setup a linux KVM vps, using as distro Fedora 27. Fedora 27 comes with Selinux enforced security policy by default this is OK for system or apps where you required a high security level, but for my case to serve a static blog and run a couple of services like OpenSSH and Nginx is ok to set the security policy on permissive mode.

changing the policy can be done via command or setup in permanent way on the selinux config in /etc/selinux/config

There are many reasons and options to choose a static site generator, but the main reasons are speed and security. Speed because it can allow more control over the content you only load what is really required without additional server side content, for security not having a database that can be compromised and security updates to apply, reduce the attack vectors and the administration work.

There are many options for static site generators created on diferent languages like:

In applications sometimes is needed check and verify if a phone number is valid or possible if the number have all required digits to be valid for this purpose there are several options to tackle the problem like regular expressions for example to validate E.164 format, library like the [Google libphonenumber](http://Google libphonenumber) and API like the Twillio Lookup for something more complete.

for this post i created a small app for test a demo purpose using the [python port of the Google library](https://github.com/daviddrysdale/python- phonenumbers)

Basic workflow

# setup the project  
git clone github/project.git  
git branch FeatureX  
git co FeatureX

# make some changes  
git status  
git add .

# commit changes  
git commit -m 'commit message'

# push changes to branch  
git push origin branch-name

# next pull request/merge with master on github or command line  

Sometimes you don’t want to track some files(like local env configuration settings)
