Hopefully you have enjoyed some of the articles I posted here throughout the years. I geared it more as a personal reference for myself and yet, it has gained a good amount of views. At this point, I will be refocusing and rebranding this blog into topics like entrepreneurship, product creation and growth, as this is now my main focus. Until then, this blog will be under construction.
Future topics will include:
- “How to properly market-validate your idea?”
- “How to go from idea to product?”
- “Don’t write a line of code before you do these things”
Reminiscing on my most visited blog posts:

This year (2017) is when container orchestration and technology will be standard and clear winners for different use cases will rise. Here are my personal notes on common paas technology, comparing Dokku vs Flynn vs Deis vs Kubernetes vs Docker Swarm.
tldr: Easy but no H/A? Dokku. Easy with H/A? Flynn. Easy with H/A and native out-of-the-box solution? Docker Swarm. Complex, but mature and scales infinitely - the big dawg? Kubernetes. Want to make the big dawg less scary but still use the big dawg? Deis Workflow.

Here’s a quick reference / cheat sheet for SQL language. The CRUD are platform agnostic. Just copy-paste this in your SQL editor like MySQL Workbench and you can step through it. Enjoy!

Both Golang and MongoDB are a perfect pair for rapid application development and
building things for scale. They both have native features that allows you to
focus on your application. When choosing a database, make sure that MongoDB fits
your requirements as it is not a one-size-fits all solution. Read the official
docs on its design and use cases. In this post, we’ll go from Installation to
building a CRUD.

I dabbled a bit of Go programming before, and after two years of not writing Go code, I decided to check it out. Alas, I fell in love, again. Why? Simply put, it is simple, yet complete. With so many layers, stacks, frameworks, libraries and opionionated “best practices” out there, there is strong cry from most of us that calls for a tool that is simple, yet complete.

Let’s use a toolkit from one of Go’s standard libraries:
database/sql. It is an abstraction and you need to import a database driver also. We will be as simple and “down to the metal” as possible. Not a fan of ORMs, so this should be fun. Whatever SQL database you use, code should be similar or the same. Read my quick start post on the actual databases themselves MySQL and PostgreSQL to get started with either.

Although my favorite SQL database is PostgreSQL due to its feature-rich capabilities and amazing performance, MySQL still has its benefits, especially in the replication side. In fact, Google Cloud SQL is only compatible with MySQL right now. If they offered PostgreSQL, I would not be writing this. But I’ll stop now on opinions. Let’s do a quick start, and compile a cheat sheet afterwards. Also, check out some tips I learned including some best practices.

Vespa is one of the simplest and straightforward control panels in the market. Best of all, it is open source! Why did I choose it? I played around with 3 control panels and this did the job out of the box, without bugs or failures. Here’s a quick way to install it in your Ubuntu server. For more features, I suggest ISPConfig. If you want to go for paid? cPanel is awesome. Before you continue, check out my guide on how to secure your linux server.

So, you have your own server? Setting up a firewall on your server is very important once it is up and running. Thanks to
ufw, doing this is fairly easy! Don’t even think about making your server public without a firewall! Check out my previous post on securing your server to add more protection.

Typically, to send email, you would need an smtp server or connect to one. Let’s use Postfix to bypass that need. Basically, Postfix is a free and open-source mail transfer agent (MTA) that routes and delivers electronic mail. Let’s start.

I will show you a very quick and easy way to properly run your process in the background. You should not use this workflow in production, but for development and quick tests, this is perfectly suitable for you.

To do this, we use the command
git rebase. Typically, it is used to:
- Edit previous commit messages
- Combine multiple commits into one
- Delete or revert commits that are no longer necessary
Let’s work through an example.

Naming in programming is hard sometimes. I typically think about the future of the app, some “what ifs”, conventions and if it truly gives a good context for other developers or users. In the end, as long as everyone involved in the project is consistent and better yet, have things documented, then that typically outweighs hardlined rules. But here is a simple guide to help make your decisions.

This debate has been labeled as the “Vietnam of Computer Engineering” and deservingly so. Here are some pros and cons I have learned.

I’m building a “cheat sheet” on finding files, monitoring and everything related to that in Linux. Here’s some of them.

For almost a year, I’ve been writing git commits in a more structured way. It has improved code reviews and skimming through code history. Inspired by angular commit messages, I adopted their commit message guidelines. Here’s are examples

Currently, Docker does not have a command to do this so we will have to do some good old fashioned command piping.
