Welcome to Han Sulu's!
Hi, my name is Han. I am the site admin of www.han-sulu.com (from here on, this will be referred as han-sulu.com). I use this blog to document some of the important adventures of my life. I immigrated to the United States during the summer 1995. Just recently I found out that I was a millionaire. Thanks to years of saving, and recent bullish stock market. I accomplished this and also got two college degrees (one bachelor, and one masters) from two top universities, had two children, and supported a large family. Over the years, I have worked with quite a few big companies, had a fantastic career, and raked in a lot of great experiences. This is the place I share these life experiences with you.
Sharing my experiences is not an easy thing to me. My comfort zone with sharing my experiences is writing technical articles. A lot of the posts I have created so far are technical articles. They are not personal. Hence they are easy. I am always amazed that some people can share their experience freely. And they are very successful socially. This makes me wonder, maybe share a little of my life can be beneficial to me. It might be part of personal growth, a good part.
What would I like to share? Lots and lots of technical articles on software engineering. I like my comfort zone. Besides this, I would be interested in sharing my experience of reaching F.I.R.E (being "Finanicially Independent and Retired Early"). I also want to write about my career and mistakes I have made. Lastly I want to write about just anything that is interesting. I am not much a writer. I hope the visitors will enjoy some of the work I have wrote.

Thank you again for visiting my site. I greatly appreciate your support.
It has been a while since last post. I changed job in September. Since then I have been riding CTA bus and L-Train to downtown. Before starting the new job, I took two weeks off. I did a lot of house work when I am on break. After started the new work, I ride CTA bus and L-train to work. Long ride and very boring. On my spare time, I was writing some small software, and learning audio and video editing, for fun and as a new skill. I need to make a list of things to complete for 2018. And I learned how to solve the Rubik's Cube from a guy at work. Finally I am searching a new web based application as project to do.
My son and I went to fishing on Sunday 6/11/2017. At Wildwood Nature Center, there were two little ponds that had a lot of pan fish. We caught nine fish under an hour. It was a very hot day Sunday. The temperature of the day is between 89 to 95F. And the fish bit the bait very quickly. I used the opportunity to try out hooks of different sizes, and how to set the hook when fish bites. My son pull a couple ones out of the water. We had a good time.
My son and I went to the lake on April 23rd. This is the second time we went, and like last time we didn't catch any fish. It was a disappointment before we left the lake. Just when we are ready to leave, we saw a guy who was pulling fish out of water one every minute. So I went over and asked how he did that. He explained the process and I learned something that day. Even though we didn't catch any fish, it was stil fun for me.
In this blog post, I will summarize the experience of writing this blog site, and the underlying blog engine. Before this blog site, I created another web site called "Java & Love". It was also using a blog engine that was using Spring MVC, Hibernate, and MySQL. After it was completed, I deployed to a server (a DigitalOcean droplet). The end result was a primitive blog engine. It was amazing at first. But I soon realized that it lacked a lot of features. So I started a new project, I wanted to create a new blog engine that would fix all the problems I found. That was about two and half years ago. The journey took about ten months. I am writing this is to bring a closure of this project. It is finally over. And I want to share about some of the things I learned along the way.
This tutorial will discuss how to use annotations to setup a Spring MVC web application, integrating with Spring Security, and Spring Rest. I started learning this about a year ago. And there were little documentation. Now, there are a lot. What I am trying to do with this tutorial, is to provide a more comprehensive example than the ones out there. What is the significance of using annotation to do a Spring based web application? Before this, you had to use xml based configuration to setup the Spring IoC container, and to describe how components interact with each other. Fully annotated Spring application frees the developer from creating a lot of XML configuratin files. And the developer can design his/her own version of configuration files to host necessary information or data for their application's needs. I believe this is the greatest strength that spring annotations for application develpoment. As you are going through the code and the tutorial, you will see what I meant.
In this tutorial, I will show how to properly use ui-bootstrap to open a popup modal dialog in an AngularJS application. In addition to this, I will show how to pass data from caller to the pop up modal dialog. And how to retrieve the results from the pop up modal dialog by the caller.
It was two years ago, I encountered this issue. I need to open a Bootstrap Modal dialog in an AngularJS application. Somehow, I couldn't get ui-bootstrap to work. ui-boostrap is a 3rd party component that can be integrated with AngularJS to support any Bootstrap related behaviors. It is quite painful to use at times. After some research I realized that without using ui-bootstrap, it is quite easy to add dynamic behaviors to Bootstrap Modal dialogs.
I like games. When I was young, I only had a Nintendo for a month. When I grew up, I had an XBox 360 for a couple years, on which I played Halo, Call of Duty, and Fallout games. When I moved from California to Illinois, I sold my XBox. I continued playing some games like Fallout New Vegas, and Mass Effect series on PC. But with two children, even there is time, when I play the game, I just felt drained. Anyways, I created this page to track all the games I like to play some day.
I received an email from host company regarding the reboot of the server. Didn't pay attention. And the site didn't auto start after the reboot. Took 10 days to notice. I don't think anyone is reading this site. If you do, my apologies. Now, I would check the site once per day to make sure this wouldn't happen again.
My host company sent me an email a while back mentioned that I can upgrade the number of CPU and the size of memory for the server of this web site and kept the same price I was paying. It took me a while, but I finally did the upgrade. This is fantastic.
It was in my Steam account for at least 6 years. I finally finished this game. There were a lot of quests, there is just no way (no time actually) for me to finish the majority of the quests. In the end, I rushed through the wild card ending. It was a lot of fun, and a lot of time "wasted". It was finally done.
I have been playing Fallout - New Vegas from beginning, then lost my saved games for at least 3 times. This is the third time. I am determined to finish it. What I have done is use cheat mode, get all my favorite weapons and explore. I play every Sunday for 2 hours. Hopefully I will finish it this time.
A new Mass Effect game is going to be available at midnight tonight. I was thrilled about it for most of the past year. The thrill is wearing off because I heard some very unpleasant reviews about it. Complexity is the real issue here, with such an ambitious undertaking, the outcome might not be the best quality.
I wasn't being lazy, it is just I don't have any free time to add new content. I have started a new coding project. For this site, I have uploaded the photos I have took of last year's convention. Enjoy!
I just published a post on my thoughts about this web site and the core blog engine that runs it. In the post, discussed the whole process I took to write this web site, and the lessons I have learned. I believe this will bring some closure to me for finishing this web site.
