I. Introduction

I have been using Unix Command Line for a while now and I can not stop talking about how useful they are. It saves me so much time not to have to touch my mouse and get lost in my Finder.

Let’s not waste time.

This tutorial is a collection of what I think is useful Linux commands that no matter how comfortable you are with your Mac, you still can use…


Mình thích đọc mọi thứ. Năm 2010, lúc đó đang học lớp 10, mình có đăng kí tài khoản Facebook và là một trong những đứa đọc “Điều Khoản Đăng Kí” của FB. Tất nhiên, mình rất thích đọc sách. Nó là sở thích cá nhân của mình.

Mình đọc khá nhiều. Mình đặt ra tiêu chuẩn là đọc 24–36 cuốn sách mỗi năm, tức là 2–3 cuốn mỗi tháng. Mục tiêu đầu tiên của mình là đọc để giải trí, để xả stress. Càng buồn, càng stress thì mình đọc càng nhiều. …


Hạnh Phúc và Tiền, Bay Area và Việt Nam.

Ở Bay Area, chỗ mình sống ở Mỹ, người ta thường nói về hạnh phúc, mọi người tự hỏi hạnh phúc là gì, làm gì để đạt được hạnh phúc. Cuối tuần đi ăn với bạn thì tụi nó toàn là bàn về triết lí nhân sinh và sống ở hiện tại. Ở Bay Area thì đầu óc kinh doanh (business mindset) về công nghệ rất cao , mọi người cũng nói về tiền và lợi nhuận, nhưng lại theo một cách khác.

Còn ở Việt Nam, mọi người thường nói…


Mình đang đọc một cuốn sách rất hay, trong sách có nói về thuyết mục đích.

Trước giờ mình vẫn luôn suy nghĩ, mọi chuyện xảy ra đều có nguyên nhân. Nhưng nếu suy nghĩ theo cách khác thì mọi chuyện xảy ra đều có mục đích của nó.

Ví dụ 1:

Khi ai đó đổ cà phê lên người bạn, bạn có thể sẽ cảm thấy tức giận, quát mắng, chỉ trích và muốn người đó xin lỗi.

- Xét về nguyên nhân của việc tức giận: thì do người ta đổ cà phê lên người bạn, bạn muốn…


(Có Sub Tiếng Việt)

When I was in City College of San Francisco, I had a chance to get to know one of my classmates who is in his 50s, mixed Irish and Native American. He just got out of jail because he committed a crime while he was drunk. He was an alcoholic.

He told me that he decided to go to school in his 50s to become an alcohol counselor. He was not sure whether he would make it to the end, to get his licenses, but at least he was trying his best. A couple of days…


Storytime: — some short fun conversation I encounter in Vietnam

(Có Việt sub)

1: “Queers who code”

They: what do you do?

Me: I am not working. I just graduated with a degree in Data Science emphasis in Computer Science.

They: oh, so you code?

Me: yes, I assume?

They: You look too gay for that though.

Me: 🧜‍♂️*sailor moon transformation reaction*

2: “A Compliment?”

Driver: your Vietnamese is so good

Me: ah ugh, but I am haft Vietnamese though. I also lived here for 17 years.

Driver: ops.

3: “Just a tip”

Friend: so you study computer, can you…


Two and a half years ago, I wrote about “How to Transfer from Community College to UC Berkeley as a Computer Science Major”, with the acceptance rate of about 6 –7%. Last December, I just graduated. I spent roughly 2 years learning English in non-credit classes, 2 years in credit classes in Community College and 2.5 years at UC Berkeley.

Throughout my undergrad time, I have learned some of the most valuable lessons that shape who I am as a person and impact the person that I want to become.

Below are four of the most valuable lessons that I…


Growing up in a small farm town, reading is a way for me to escape and also enjoy myself. Books remind myself that there is so much out there that I can see and experience.

Below are my top 3 books that make me always want to go on adventures:

1: Doraemon:
Nobita and Doraemon are the pair of friendship we thrive for. With Doreamin tools, especially Takekoputa, the manga series have changed generations of children in Vietnam and Asia. …


I: Lessons that I Learn

1: How to care for and love someone even we are not together.
I broke up with my ex-boyfriend at the end of 2017. He was the first one that I felt love and beloved. It was very hard for me to move on. In fact, I did not move on until I knew that he has a new boyfriend.

2: Getting to know people better.

I gave myself an excuse of busy with school and my own life that I did not get to know people around me better.

Friends used to live in the city moved far away.


My dear friend, Josh, just passed away in December. The news was sudden. It was hard for me to believe in it.

I knew of Josh through other mutualy friends. He is very sweet and always very supportive.

I was very stressed about school. He was one of the few people who slide to my DM to support me. He offered help if I needed any. Whenever I had a chance to see him out in public, he cared about what I had to say. I rarely went out so he wanted me to have a good time.

I went…
