nginx improving SSL Configuration

Improving SSL Configuration

  • Documentation:
    • NGINX ssl module
    • Mozilla’s Server Side TLS Documentation
  • Add session caching so that fewer SSL handshakes need to be made.
  • The initial handshake is the most taxing part of the process, and if we can avoid repeating it then we’ll improve our overall performance. 
    $ vim /etc/nginx/conf.d/default.conf

ssl_certificate /etc/nginx/ssl/public.pem;

Force Delete user in mac

Can’t Delete Original Admin User on macOS High Sierra

Reference: Medium Article by Ambrose Little

I recently migrated to a new MacBook Pro. The old one was on High Sierra, but the new one wasn’t. So I created a temp “admin” account to do the upgrade, then do the migration with Migration Assistant.

All seemed okay, but when I went to delete the original user account, I couldn’t. And I don’t mean “you don’t know how to delete accounts” couldn’t. I mean, I tried every possible way, and it wouldn’t couldn’t.

I found this thread on the Apple forums with people having the same problem. After trying everything else, this is the solution shared in one of the replies that worked. Warning, I have no idea of the side effects this might have, but so far so good for me. Also, do not come crying to me if it totally hoses your machine. You’ve been warned!

How to make a release with Git and Maven via JGitFlow

How to make a release with Git and Maven via JGitFlow

Imagine that you are versioning your sourcecode in git and building your code via maven. You need to make releases before deploying to production regularly. What should be the strategy we need to follow for releasing?

I've used maven-release-plugin for years to make releases. It worked perfectly with maven and svn, but we started to face problems when we migrated our code to git and to make releases on git.

After checking the literature, we decided to use JGit-Flow which is a maven plugin based on and is a replacement for the maven-release-plugin enabling support for git-flow style releases via maven.

I do not want to explain the details much because there are many great posts explaining all.

disk filesystem (df) & disk usage(du)

du == Disk Usage. It walks through directory tree and counts the sum size of all files therein. It may not output exact information due to the possibility of unreadable files, hardlinks in directory tree, etc. It will show information about the specific directory requested. Think, "How much disk space is being used by these files?"

df == Disk Free. Looks at disk used blocks directly in filesystem metadata. Because of this it returns much faster that du but can only show info about the entire disk/partition. Think, "How much free disk space do I have?"
