Golang Pointers

Pointers in Golang are a little bit confusing since my background is PHP where there is no pointers at all! During exploration, I ended up writing a bunch of “note to self” on my code in able to grasp this subject.

I hope this note of mine will help you to understand Pointers.

Virtual Hosts in HHVM

This is a simple way of creating Virtual Hosts for HHVM. When you’re doing this on your local machine. Don’t forget to edit your hosts file and add a loop back to the domain (ex. 127.0.0.1 collideborate.local)

#hacklang #hhvm

Since it’s not ideal to use mail() function of PHP when sending bulk email for notification. I have to figure that out using Rust.

#rustlang

#web accessibility

There's an instance that the default mail port was blocked for security reasons. Now, the hacker way to test SMTP on your initial setup is use cURL. It's available on many UNIX/Linux platforms, so no need to install another package - Don't double the simple work.

Authentication failed on my Pull Request

I used to use password when pushing my code on my Bitbucket account. On Github, it’s different. My first attempt on “git push” for my Pull Request was epic fail. I got the error below.

Issue: Authentication failed

Fixing the Issue

To fix my issue, I have to follow this documentation.

https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token

Lesson

The lesson is, instead of using your password. Use the generated token from your Github account for security reason.

Is it add2 or suspended2?

Out of curiosity. What’s this mystery 2 on this chord chart!? In my opinion, this naming convention is ambiguity and for the musician who doesn’t have knowledge about the theory of intervals, it’s either forget about it, skip that 2 and just play the C chord or search “C2 chord”. Now, they are clueless about suspended chords. This is the problem of using shorthand. We are not introducing these sus2 and add2 on their vocabulary.

But wait! What’s the difference? [To be continued]

This is one of the reasons why I build https://collideborate.me/. For the sake of learning. Every time I create a piece, I always indicate if the chord is suspended2 by writing Csus2. Likewise to add2 by writing Cadd2. Now the chord makes more sense, including for the newbie. Now the major problem is learning the intervals :)

Logging system calls in *nix

Logging serves as our ”eyes”. Without this, we cannot identify the bottleneck of our application that consumes a lot of resources. Keep a habit of logging and tracing before pushing your code on production. [To be continued]
