I think this is a very special place and one that I'm particularly fond of.
A collection of random thoughts and materials that might prove enlightening to me and my friends.

Workload
It's one of those moments when you felt your intuition is correct and you have put in significant effort to start the process, but all of a sudden you have been told your intuition will not lead you to the usefulness people see in you in the future.
Now I'm taking a step back and make sure I will not lead myself astray but trust the guidance of an expert more experienced than I am.
Anyway. It's complex.

How do you get gigabit per second over the air?
This question is still keeping my awake during the night.
- Multiple bits per symbol is a given; there is simply no technology out there that can digitize at gigasample per second.
- Multiple antenna - how do you pack up to four antenna to a device? I can picture that being possible on a decent sized laptop, at 5GHz or more, over short distance with a favourable channel.
- Getting gigabits to the home. This becomes a question of what type of infrastructure is required to do just that. Fiber to the home, and a wireless access point (femtocell). A cell tower managing hundreds of gigabits of data over the air will be challenging.
- A lot has to take place, similar to idea of fuel cell vehicles. Infrastructure is a significant issue.

Simulations
It appears most simulations are done in a Linux environment. Research tools are both open and actively worked on by the academic community as well as the industry.
However, a fair amount of practical implementation tools are developed on Window.

Illustrations in Latex documents
I've searched around for tools to help with creating diagrams. The closest contender seems to be something that is vector based and supports importing and exporting eps format.
One expensive choice is Adobe Illustrator + MathType. Even at student price, Illustrator is still prohibitively $$$.
A good contender is Inkscape but it's not mature enough for dealing with importing eps equations and editing them in place.

Testing formulas
This is a cool way of adding formulas to email/blogs. However it's not supported natively on the browser. Under the hood, it makes a request to a server for an embedded gif image.

Thought record
Now is the time to blow the dust off my blog and start something substantial. I'll have to see what I want to place on here. I'll start off probably by writing what I've learned during the period.

The art of moving...
Don't let anyone tell you moving is not stressful; when you have to cross the border that complicates the matter even more.
I understand now how much my dad had to go through when he moved our entire family over. That must have been a feat of enormous proportion. He moved into a completely new culture with a different governing system. But I had no idea at the time, since I was still trying to understand why we moved and coping with adjusting to yet another move in my young life - I was 14 and rebellious.
From HK to England, to Toronto, to Waterloo, to Ottawa, there was not once that I had company while I moved. From Ottawa to Waterloo, and now Waterloo to San Diego, I'm going solo. The lesson I learned from this is that a modern mercenary has to be mobile as ever. You simply cannot keep too many things.

Piotr Wozniak's prescription to becoming a genius
When someone spends his whole life mastering the technique of learning, you listen...
Clarify your goals, gain knowledge through spaced repetition, preserve health, work steadily, minimize stress, refuse interruption, and never resist sleep when tired. This should lead to radically improved intelligence and creativity.

Reflections on 2007
2007 is another challenging year for me.
I have to fight another severe episode of depression. Luckily, I have the help of my dad's friend and a renowned psychiatrist Dr. Wong. He came to the rescue in April and I was fortunate to receive treatment immediately in April. I have been doing quite well now, continuing taking anti-depressant, and I have also kept in constant contact with a local psychiatrist and a very good psychologist in case I needed immediate attention. It's funny how my doc parallel this condition to a diabetic, but again, I am more fortunate than a diabetic because I don't necessarily have to be on medication all my life.
At work, I have created a comfortable environment for myself and I am working quite autonomously. I have gain much respect from my peers so there is now synergy at work, I am spending much less time working on issues.
I have been continuing my goal to establish myself in the soccer field. I am happy to say I have succeeded by being promoted to captain for our dept soccer team for next year. Although my ultimate goal is to coach little kids, not big kids, but it's one small step closer to my goal.
I am continuing my work helping people around me and helping the students at KWCAC. They are a handful but I think I am now enjoying my time helping them. It's a very satisfying experience.
Lucinda has been my big sister and continue to have strong influence on me in my quest to become godly. She is a wonderful person and I will learn much from her.
All my brothers are now in North America, within an hour flight from each other. I think this is the start of something tremendous as we can co-ordinate our activities with much more efficiency than before.
I am looking forward to 2008 as I believe this will be the turning point of my life and the lives of the people I care and love.
