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.

Let me google that for you

I must share this link. I'm sure a lot of people know this site already.
Let me google that for you.
I made a Chinese translation for that site a long time ago.

I forgot this site until these days when people start to ask problems that are so easy to answer from Google.

Go use this when ever someone ask one of those common questions.

I don't mind people ask me questions. Especially questions that do require me to think, or things not easily googled. Like "how would you do this problem?", "when will the school play start tomorrow?"(btw I never know when the school play starts).
I don't like to answer to some questions that's perfectly google-able.

It's like asking me "what does this word mean?" when there is a dictionary right beside you.

Infinite loop

I saw this joke.

Boss to Secretary: I want to go to Beijing for a few days. Come with me.
secretary to husband: I have to go to Beijing with the boss.
husband to mistress: my wife won't be at home for a few days.
mistress to student: I won't be teaching you for a few days.
student to grandpa(boss): I don't have classes for a few days, let's have a fishing trip.

so, now, as you can see, the reverse happens, where boss->secretary->husband->mistress->student change their plans...
How can this problem be resolved?

Maybe one of them had enough with this and chose to do one thing anyway.

Maybe one of them become scientific and start investigate.

I don't know...

Edit: Helie offered a solution!

Obviously, the solution is to go fishing IN BEIJING

225 boxes

225 boxes from USPS arrived yesterday, packed inside 9 large boxes.

Totally random.
few days ago a conversation like this with Kirkland.

K: Do you like boxes?
M: Yes
K: Do you like large boxes or small boxes?
M: Large boxes
K: Do you like a lot of boxes or a few boxes?
M: I like a lot of boxes.

That's the result. 225 boxes sent to my house.

I heard someone planning a prank in my school, where people use cardboard boxes to block the hallway from B-wing to C-wing. Epic. put water in it so anyone knock it down gets really wet!

So what did I do with these boxes? I throw them away.
My dad returned home and freaked out, he found this extremely irrational and ordered me to get rid of those things.
At first I thought of dissolve the cardboard, then I found there is no sulfuric acid in my fridge. Lame.
200 boxes are thrown out today. I left 25 just in case I have to use it for something evil.
