Hellow, no matter who and where you are, I wish you a good day!


Had been a years since I finished the long journey, and it would be nice to share things that I enjoyed during my first journey into the universe using the astrophysics undergrad student pass. Challenges, beautiful…

Hi! Welcome to my first 30 minutes hacks! I started this program because I am not sure how to start big, so why not.

Recently I am having interest in cryptography, since Hackthebox is really engrossing. However, I promise this one would not be hard.

Astrophysical Introduction to Spectral Types

Star spectra is a gold mine for astronomers. From spectra, much valuable information about a specific star can be gathered, such as surface temperature, surface gravity, and metallicity. …

Hello everyone,

I want to celebrate that finally I have a part-time dream job as a coffee barista, and I am on my way of training (well, not that kind of training of course). If you ever met me in person, maybe your impression from my look is not about…

Hi! so I got promoted to a new position in my company to handle NLP and NLU problems since previously spent my time in the computer vision department. I am not actually fresh into this area, since I was previously exposed to RNN in the deep learning university course. …

Months ago, I started to use Fast.ai for deep learning. The course was very lightweight and intelligible. The course also covered image classification deployment, which classifies teddy bears, grizzly bears, and black bears. What I did was to modify it as a coffee classification problem. As simple as that, because…

Hi, following my previous post about YOLOv3 object detection below

And this time I jumped into YOLOv5 (yes I tried the v4, but not yet hyped so I tried the v5) for object detection.

YOLOv5 has pretrained model which included 80 classes as the previous model has. I found that…

This time I will write about Darknet and YOLO Object Detection, and some tutorial on it. I knew them from humanoid robot research, which needs computer vision and machine learning to detect an object. Since I am a big fan of C++ (to differ me upon what so-called as “modern-time…
