👋 Hello everyone, it’s Tony again.
Lots of things happened in October 2021. I released DevUtils 1.12, worked on a new exciting feature for Black Magic, moved back to Vietnam, and other small updates.
Just want to say this quickly: Thank you all so much for following my journey! I hope my newsletter is helpful to you, I really enjoy writing it, and I hope you enjoy reading it too!
Let’s get started.

👋 Goodbye Singapore 🇸🇬, hello Vietnam 🇻🇳
I’m happy and excited to return to my home country!
I started working in Singapore ~3 years ago, I love my time there and I love the country.
Quitting my day job means I can’t stay in Singapore anymore because there is no visa type for foreign indie hackers/digital nomads. It’s unfortunate.
On the other hand, living in Vietnam gives me a much longer runway for my indie journey. My saving will last much longer here! I also miss the food so much!
Looking forward to sharing more with you all on the next phase of my journey! 👊
🔨 New update for DevUtils
In October, I released a new update for DevUtils with a lot of new features and improvements.
Most noticeably, the new RegExp Tester now supports group matching and named capture group.
There are a lot of other changes and new tools. If you haven’t seen the changelog yet, check it out here!

🐍 Fun stuff I did with my banner (again)
This idea has stuck in my head for a while, I decided to finally do it: build a Snake game on my Twitter banner!
I let people play snake on my Twitter banner
I let people play snake on my Twitter banner
The way it works:
  • Someone comment ➡️⬇️⬅️⬆️ emojis to my tweets
  • I use Twitter API to read the emojis
  • Use the commands from the emojis to control the snake
  • Then I update the latest game state to my Twitter banner.
It’s fun! 😂
The tweet got 675 replies, the most replies I ever had in 1 single tweet ever!

Go play snake on my Twitter banner, yeah!

To control: reply to this tweet with ➡️⬆️⬇️ or ⬅️

For example: "➡️➡️➡️➡️⬇️⬇️⬅️⬅️"
I “recreated” the live banner and compiled it into a short video, you can watch it here on my YouTube channel.
