Human Identification Number

Many country have national identification number for their citizens(even non-citizens).
How about a universal human identification number?

This number should be powerful(as powerful as SSN) and we can show it in the open. Not like SSN, no one can put them online.
Why can we put our AIM user name and other usernames online? Because the number itself isn't the only way to authenticate. There is a password too.

We also need a government agency that authenticate if a person is who they claim to be.
Then it's possible to have 1 ID for EVERYTHING.

There is a similar idea. OpenID.
How about, government create something similar to the OpenID and replace it completely.

We can establish a world identification organization in the united nations... but hey, having a one world government, it be much easier to enforce rules.

Human civilizations have developed for this many years, and there is no unified government yet. Humans, I am disappoint.

Nice thing in life

so everyday, I do this command
vim blog.txt
and then write down things I care about, and post it as a blog post at places once in a while.
Yeah, awesome.
I keep this window open, so it's fast as I can switch to it and type something. LEET

Major hierarchy

This was inspired by programmer hierarchy.
Version 0.1. This only include majors I actually know about.
Math, Applied Math, Physics, Computer Science
An arrow means one thinks one is superior than another.

Oh wait, it's a complete graph.

I suck at calculus

Calculus are for engineering(especially physics related) students. I thought a Math/CS majors like me would never use calculus after the completion of the calculus sequence. I don't intend to learn calculus to the point that I can do integrals like my second nature.

Then today I was doing AMS 311's HW 5. It requires immense calculus power. I wasn't aware of how much calculus was required for this course. Now it replaced CSE 541 as the hardest course ever.(CSE 541's midterm is pretty ez, in fact, I feel CSE 541 is really really ez now... as long as I understand the tower of definition and really long proofs)

I should have seen it coming, it's a AMS classes that have to work with continuous functions. AMS don't use analysis to prove thing, they calculate stuff. Calculus is RIGHT THERE.

This is not the first time I noticed how I suck at calculus.

I never got calculus. so what if I got 9 in math placement because of the AP test. If I go and take a MAT 131 final right now I would surely fail.

This lack of calculus skill have struck me at least 3 times since I'm in the university.

1. While doing MAT 305, I found it's impossible to do some integrals without a table of integral around me. I also have to look up integration by parts.
2. People around me who are in calc 1 or calc 2 would ask me calc problems. and I can't answer them without help of mathematica. In fact, why ask me when one can use Wolfram Alpha? I can't provide any more insight than rephrase the question in a way a computer would understand.
3. During Putnam, I skipped any problem has differentiation or integration.

I remember I was having breakfast last semester, and someone gave me this simple limit problem, and I can't solve it even when I have finished breakfast. What a disappointment, people believed I can do MAT 131 level problems because I was in more advanced math courses. No, I just do different kind of math.

I'm sure I can improve my calculus problem solving technique to among the best by finish Demidovich's book of around 5000 calculus problems. I see no point in that though, since AMS 311 might be the last time I will ever really do calculus.

Web design and interface

There are many different websites running on different themes.
Some websites have the same kind of sections, but presented in a different way.
For example, the navigation is on the right instead of left. Recent comment bar is showing on the bottom instead of top or w/e.
Each time I go on a website I have to get used to the interface.
If I'm only going to use this website once, it still take time to find information I need.

Semantic web is nice. Because I can ignore all the web design, and apply my own set of templates on all of them.

Semantic web NOW!

I have to complain because I have nothing better to do. Now I'm happy and going back to study for the midterm.

I wish I can get paid for complaining.
