What are you truly capable of?

Have you thought of this question? You used to eh, but experiences brought you down to earth. Life hasn't been so kind, eh?
A while back this happened to me too.. Experiences dashed my expectations.. totally devastated my aspirations. I went through a period of introspection, a reality check basically. I regrouped my self (literally), assessed my situation and decided that
giving in my best in whatever I do is the best thing to do.
'I will give in my best. It doesn't matter what I am doing. Give in your best. opportunities will come knocking. Keep giving in your best.' Well, yes this policy did help me out. I am on a new path right now having steered clear of my old self, old life, old surroundings. Life is uncertain, but I am beginning to accept that.
When you are an undergraduate, you are in a secure, protective cocoon. You feel you are invincible, that life is going to be smooth sailing when you graduate. No my dear, no. Life isn't smooth sailing. Life is about being smooth during rough sailing.
Life rocks your boat, but you got to maintain your calm. You got to be an unaffected observer. Life teaches you through experiences. Every calamity in life, every miserable moment in life is indicating something. It is upto you to introspect, investigate that misery and come to a new understanding of what works and what doesn't. The sooner you do that, the sooner you learn.. your lessons. And then it's smooth sailing for a while, until you get rocked again. But this time, you are quicker in learning the lesson... noticing a pattern to the experiences..A high always is followed by a low and vice-versa. The bigger the high, the deeper the low.
And this understanding changes your character, slowly but gradually. You realize the importance of equanimity..you place a high emphasis on being equanimous. You recognize that equanimity is a deadly weapon, a powerful tool to handle all that life throws at you. Through equanimity, you realize that life hasn't be throwing the kitchen sink at you as you imagined.. you realize that life has actually blessed you with cleansing opportunities... experiences that force you to clear the old and bring in the new.
Ok, we went off on a tangent or a secant there, it was hard not to. Let's get back to the original intent of the post. 'What are you truly capable of?'
Being a dreamer that I am, I ask myself these questions once in a while. I think it doesn't help being a dreamer. Why? Because, I think what you are actually, truly capable of in life goes beyond imagination. But dreaming does help me get atleast one light-year close to what I am truly capable of. I recognize that dreaming is not enough. Dreams need to be translated to reality. Well, this isn't something new, as you might concur. All technology that we use today was dreamt by some great dreamer.
But the dreamer also converted his dreams into reality. That's what we should aim for. We should first dream up the great person within us, whom we are yet to experience and then we convert that dream to reality - That is we become that great person, that humble albeit astounding personality, that equanimous character who lead by her/his example, that leader who left an indelible footprint on the sands of time. We dream, we become. We dream, we become. So on and on.. until infinity. Welcome to the game.. called life.

Positive definite matrices and quadratic minimization

I was looking to understand more on positive definite matrices and a couple of theorems. I found a nice summary of positive definite matrices, their properties and role in quadratic minimization on the web here. Another link here. Another here.
Also an ultra-quick summary of Linal.

Lessons from the teaching assistantship experience

I. Introduction
I have been a teaching assistant in udub for about 2 quarters (including this one) and I find it to be a rewarding experience and a continual learning experience too. My job is to hold quiz sections twice every week where I go over examples to better explain concepts from the lectures and also give students some practice problems. I also help out with some grading. Believe me, this is not an easy job at all but at the same time it is a fulfilling and creative job. When you develop new, ingenious ways to communicate ideas and concepts to students and they "GET IT", that's awesome - that's why its fulfilling, that very feeling of having given your all into the job gives you back a feeling of fullness.

II. Key elements

From my limited experience , the key elements I have found for a successful quiz section are:

1) Know the content thoroughly and anticipate potential questions: You have already taken the course you are TAing, that's why you are qualified to be a teaching assistant. But knowing the concepts on the surface isn't enough, you got to be able to explain them, analyse them from all angles, think of potential questions students might come up with and see if you can answer them comfortably. To be able to explain content requires different preparation than just knowing the content and hence sufficient effort needs to be put in here depending on your knowledge of the subject.

2) Get to know the students, atleast their names: This is important, since your ideal quiz section is one where students are involved in it and find it interesting and useful. Knowing their names makes it easier to engage them and increases their participation in the quiz section. Eye contact is also important, you need to make them feel comfortable. These things come easily for some people who are more sociable than others. I am more of an ambivert and hence had to put some effort to get this connection thing going.

3) Make the quiz section interesting: Depending on the composition of the class, students may or may not be able to follow the class easily. If they follow the class easily, they would expect more than other students, who would be content with practicing problems related to the homework or quizzes. I try to bring in one or two examples from outside the book that the students can relate to, find interesting, and also helps their understanding of the concepts.
Cracking a joke or two now and then will also help lighten up the mood.
Variety is the spice of life, but it can also spice up the quiz section. This is something that keeps me interested too. I try out different things every quiz section, see if it works and imbibe it into my "teaching model" if it does.


4) Organize the quiz section well and incorporate time management:
Organizing or structuring the quiz section well gives the students a good idea of what's coming next, sets expectations (which isn't necessarily a great thing) and keeps them involved. Last quarter I was always on time for my quiz sections. But this quarter, I need to wake up by 7am and go to the quiz sections by 8:30am. I have had problems with the bus not coming on time and traffic signal delays. So basically, I don't have a time-window for uncertainities such as delays. It's good to be efficient but not at the cost of coming to quiz sections late every now and then. So I realized that early and am catching an earlier bus that gives me enough breathing time before I begin my quiz section.
It's also good to have a schedule of what you are going to do when during the quiz section, so that the quiz sections are efficient and the students get more out of it. Ofcourse, you have to decide the level of efficiency since being too efficient might come at the cost of rushing through the quiz section.

So that's a good summary of what I think has helped me out in the quiz sections.

III. Challenges

1) It has not been easy at all as I mentioned earlier. I wasn't given an agenda of what's to be done in the quiz section last quarter. A few examples and asking students to work out problems was what I was told. You know, just following those instructions isn't going to give you the greatest quiz section at all. When you realize that, your learning process begins. You begin experimenting, infact what you are doing is you are researching your teaching skills through experimentation!! Isn't that wonderful to be able to research your teaching skills on the fly, without reading any papers!

2) Feedback from students was my main motivation for improving the quiz section. Ofcourse, I would get feedback from students even when I didn't ask for it and sometimes, in a rude manner. Dealing with such cases was also a challenge.

3) The main challenge I would say is coming up with a basic, working, "quiz section model" that is good as it is, but can be improvized. That working model, is what I have described in the second section above.

The "Clicking problem" in laptops (mine's a Dell)

Does your laptop "click" incessantly when you are doing even mildly intensive work such as opening documents or running a small software?
Does your laptop "beep" every minute or two when it's idle (This problem might be exclusive to dell laptops).

Well this problem has got to do with your hard-drive's power saving features (unless your os starts to crash - Then it might be a mother board problem). If your computer's pretty ok except for the "incessant clicking and ocassional beeps", do visit this forumpage.
It gives you a step by step procedure to minimize the noise due to those "clicks".

To summarize the solution in the forum page:
1) Install Microsoft .net 2.0 version from here. If you have an earlier version of .net, uninstall it before installing version 2.
2) Install NHC (Network Hardware Control) from here. Note: users of Dell laptops such as Dell Vostro, Dell Inspiron, etc use the Dell bug fix version on the same page. The other version would give you an error when you try to install it.
3) Run the installed NHC 2.0.
4) You should see an icon to the left of your desktop icons that looks like a big battery.
5) Double click the icon.
6) In the window that just appeared select the Settings tab
7) Click Show all NHC options and settings
8) Now select the Hard Disk tab, and under Advanced Power Management select the highest setting: Max. Peformance Mode

Voila ~ you are done!
Now you can enjoy blissful sleep when your laptop is idle(a.k.a those painful beeps vanish). Also, if you want to work in a very quiet place, the "incessant clickings" would become incessant whispers that are hardly noticeable.
Enjoy the peace and be peaceful :-)
