What is DevOps

There are several ways to look at the DevOps “brand” and even in my circle of collegues, there isn’t a a absolute true.

Found this on the web and looked pretty cool.

Four friends sitting round a table, one pips up and says "I want to work in DevOps"... The other three are seasoned IT professionals reply:

    So you want to be a UI developer?

    So you want to be a back-end developer?

    So you want to be a infrastructure administrator?

    So you want to be a network engineer?

    So you want to to be a security engineer?

    So you want to to be a database administrator?

    So you want to to be a support administrator?

Suddenly a consultant barges through the door and says: No, that's old-school and obsolete. Methods of continuous delivery means in-depth expertise in specific fields is no longer required, convergence is order of the day. He wants a role that synergies and leverages these, to deliver a paradigm shift. (Then proceeds to submit an invoice, followed by a quick exit stage left)!

Lastpass get owned once again

How can someone still rely on Lastpass to keep important stuff?

Seriously, look at their blog and count how many breaches they had on the months.

Screen util - Tips & why to use

Ever happened during some server installation, you really need to pack up and leave? That happens to me almost every day and in the old days, I had to stop what I was doing and start all over again the next day.

Now I use screen as much as I can.

The exact definition of screen can be found here and it’s like this:

Screen is a full-screen window manager that multiplexes a physical terminal
between several processes, typically interactive shells.

Basicly it’s a always on shell within the shell.

First let’s install it everyhere:

For Debian/Ubuntu:

apt install screen

For Fedora:

dnf install screen

For Centos/Redhat:

dnf install screen

For MacOSX:

brew install homebrew/dupes/screen

After it’s installed, just run it: $ screen

First what you need to know it that CTRL-a is the command/super key.

For example:

After launching screen, run top in it. Now, what would you do to see a log file? Probably you would exit the top and see that log file or even star a new ssh login to your machine in order to do both actions at the same time but with screen you don’t have to.

Press CTRL-a c and it will create a new window. Now run a free -m.

You can cycle the windows by pressing CTRL-a n.

It’s like several virtual desktops in your terminal. Isn’t that cool? But wait, the best is yet to come.

If you need to quickly logout but want the top command to keep on running, press CRTL-a d to detach from that screen.

You can even logout from your server and the top command will continue to run.

When you return to your server, run the command screen -r to re-attach to your screens that stayed running in the backgroud.

So in review:

Njoy.

How to post from Github with Markdown and Wordpress

I just found out that I am able to write my blog with markdown and use GitHub to store my articles.

This way I will always have my articles secured and I will never lose my articles again (I think I am even storing my pictures inside the repo).

Im currently using a plugin called GitHub Readme

THere are some ways you can use it:

[github_readme repo="abacao/abacao.github.io"]

With this you can use: trim, branch, and cache (seconds to cache)

Some examples:

# Remove the top 3 lines
[github_readme repo="abacao/abacao.github.io/_posts" trim="3"]

# Points to a specific files.
[github_markdown repo="abacao/abacao.github.io/_posts" file="2017-03-08-openstack.md"]
