Some thoughts here and there

I finally get to blog! I have been meaning to write this whole week, but every single day something keeps coming up. I had three birthdays this week, and there's always something to do around the house. Plus this week I've been getting up early to go to work early, and I am really tired by the time the kids go to bed, which is when I usually have some spare time to do these things. But I've had these thoughts about these things I want to share here and so here it goes.

Philosophy is for everyone

So last week I finished reading Plato's Republic. Now, that sounds so...intellectual or something, right? well no, it is not, I found Plato deeply approachable. The book is not only about Government, is much more than that.

I can't read a book more than once, but I think I am going to make an exception for the Republic. I have the Spanish edition that belonged to my father and a new copy I just bought when I was at Chicago. Anyway, I would read a chapter in English and then I'd do the same in the Spanish version and I would always find something in the second reading that I somehow missed the first time I read it. I know I probably didn't do a good job of "getting" everything about the book, since the book itself is so rich, and I was reading a few pages right before falling sleep. However, there are a few things that stuck with me.

Justice

I remember hearing about this when I took an undergraduate course in philosophy, but when the teacher mentioned the word "justice" I thought about the Judicial system, meaning justice as punishment. But Plato is not about that, it is a dialogue where they discuss what does it mean to be just.

One of the things that I keep thinking about, is the question: is it better to be perceived as just but in actuality not be just? or is it better to actually be just, but perceived as unjust? The issue being, should we be just just for its rewards or is there something good about being just in itself?

In politics and business perception is reality, but we see how CEOs politicians and the like don't always do what they preach, which tells me that they would rather be unjust but be perceived as just, which explains why so many people distrust politicians.

Another thing that caught my attention was how Plato classified people, he divided people by those who love wisdom, those who love money and those who love honor (soldiers).

I see that we all have a little of each, I would say that there are those who seek pleasure, those who seek money, power, fame, and wisdom.

I see the utility and the necessity to have money, and I don't think there is anything wrong in being industrious and seeking to create and accumulate wealth. But the love of money changes people. I turns people into conniving, lying, calculating creatures that lack compassion, I think that greed can be a very bad thing, a person who only loves money and pleasures will never be satisfied.

Same kind of goes for people who seek fame, power, honor, just for their own sake. Those things by themselves do not bring fulfillment. The thing that Plato said that I will carry with me forever, is that the love of wisdom is the best thing we can aim for. It's a simple yet powerful concept.

Another thing that I really liked, and there's a lot gems like these in the book, is the part where it explains that true freedom comes from being able to control the passions of the soul. It seems paradox, but, self-control actually gives us more freedom. When we lack self-discipline we become slaves to our vices and appetites.

Anyway, I highly recommend it to everyone, books like these are classic for a reason, they have survived the test of time. Generations and generations of thinkers have written their ideas but all most of them are either a response to or an echo of what Plato wrote. That's awesome.

Founders at Work

Reading a great book about how some great companies got started. Eye opener. I know that I will never be a businessman, but I will not be ignorant about the subject. I am going to get more knowledge in economics, finance and accounting. I want to know how to read contracts and how to run a business, it will come in handy someday. However, I want to be an engineer all the way, I enjoy making things, but the temptation to start a company has been there, maybe someday...

COP 5555

This week I start the famous compiler class in UF, is my second Computer Science course in Grad school and I can't wait, I actually want to start reading the book now. It can wait though.

Ok everyone, that's all I have. Be good.

YES!

I just finished my final, well, I just solved all the problems that were assigned, it was a take home test. I still have to put all the answers in pretty format, need to scan it, same with the project, it's all done, but have not turned it in yet.

I was sitting here, not knowing what to do, so many different different things that I could be doing. I have more interests than time, so now that I am free, I am having a hard time deciding.

One of the first things is going to have to be fixing up the house, we have had the stairs bare for the past couple of months, long story short, it's a home improvement project from hell, everything that could go wrong in a home project went wrong.

I have a few books on my queue that I want to finish. Martha just gave me a copy of 1776 the Pulitzer-Prize-winning best seller about Washington's fight against the Brits that year. Thanks Babe! I am about to finish reading Plato's Republic, and well, you've seen what it has done to my blog writing, it has me writing dialogues and what not. Reading Plato makes you want to really think about things, think clearly. I don't know if that makes any sense at all, but that would be another post.

I also have Founders at Work, a collection of stories about successful startups, they should also have a book about failed startups as well, lately, I've been getting more interested in learning economy and business, but from a scientific perspective, I am curious to know how the world works, people are motivated by economic and political factors. I am wary of people who are obsessed with money and money making, but it would be foolish to ignore what moves the country and the world. Also, realizing that although I work as an engineer, I am make money because of a business, and all business is sales, therefore, I need to make innovations that sell, not just things that are neat, or impressive, but to make it as an engineer, we need to work on stuff that's profitable, that's reality.

Open Courses

The best thing thing in the internet besides Wikipedia, is the increasingly common practice of putting the content of classes for free in the internet. At the forefront of this effort is MIT. They have been putting a lot of material out there, and not just their world-famous engineering courses. Check it out for your self. ocw.mit.edu


Yale University's Open Courses, while not offering as many classes as MIT, does offer one unique advantage, the course transcripts are provided, so I don't have to watch the lecture, I can just read it, this offers multiple advantages, for once, I can read it a lot faster than I can watch it. It's better for my embarrassingly-short attention span. And I can read it pretty much from anywhere, my phone, laptop, without having to wear headphones or anything like that.

I started out with the New Testament and Old Testament classes, I struggled a bit with the Old Testament stuff, some of it was kind of boring for me. But the New Testament course was fascinating, there are so many things in the New Testament's text that reveals so much about the history of Christianity, and I never noticed it. It's there, in plain sight, you just have to open your Bible and read it. Text Criticism was something new, I just never studied the Bible that way before.

But the class that compels me to write about this is the new course I am looking at, it is called Introduction of Political Philosophy, and it just hit my brain's sweet spot. It deals with the idea of the "Ideal Regime" the questions that are extremely relevant today have been asked for a long time by some great thinkers of the human race, learning about it is an awesome experience. I think that's what learning is supposed to be about. I think this is one of those course that will shape the way I think about politics for the rest of my life.

Well, that's all for now, I am sitting next to a fireplace in a Panera in Schaumburg, it's 6:30 AM, and I am headed for the office, long day of work ahead of me.

Be Good to each other.

Stress can take the joy away from anything

I truly enjoy figuring out how things work. That's why I am in grad school, I find all of mathematics fascinating, elegant and beautiful...(just like my wife). However, It has been difficult for me, I keep taking these test where the problems that are given to me take me by surprise. There's nothing more discouraging that sitting in a test with a question you have no idea how to answer, not even how to begin to approach the problem. Somehow, that hasn't stopped me from trying. In this grueling process, I have learned a thing or two here and there. Here's what I'd like to share.

You don't know crap until you've done it

That's true, Anyone can read and memorize technical jargon until they are blue in the face, but to really know something, you have to put it in practice. You can't become a good runner without running. You can learn all you want about painting, but nobody can call themselves a painter until you actually paint something. Same thing with engineering, you have to put things together, try things out, make it work, and then the theory solidifies in your head.

Grades don't really mean crap

Ok, it's funny that I say that now that I am no longer getting good grades, but it's true. Yeah, I used to get good grades in my undergrad, but I wasn't trying to get an A, I was really trying to get to know the subject. I knew people who would try to do just enough to get the grade, and not more, any "wasted" effort learning something that wasn't necessary to get a good grade on the class was in their eyes, an inefficiency, the whole point was to get the degree so they could check that box. I, in the other hand, became thrilled when I realized how much there is to know about computers. I had to work hard for the grades, but usually the more effort I put in a class, the easier it was to get an A.

Not Anymore.

These days I study, I memorize, I read, I try to comprehend, but there's so much material, and it's all so new, I feel I've met my limit, however, I am not defeated, I will keep going. I will not give up. I am trying new things, for example, (and this may sound obvious) but I am going to try to concentrate on solving problems, practice, practice, practice. Also, I am going to try this thing I heard somewhere, I am going to try to write all the theory concepts in my own words, that way it forces my brain to process it. It's tough to do with the abstract math, but it helps.

Anyway, I have to go now, Gotta help pick up the house we have visitors coming.

Later ya'll.

Be good to each other.

Academic Battle

I have been trying to learn a brand new professional skill for the past 12 months. It's called Digital Signal Processing. About this time last year I made the decision to focus my Master's Degree on Electrical Engineering as opposed to Computer Science. Ironically, that decision was based on the assumption that a degree in C.S. would be too much work (because of the programming assignments) and that DSP would be easier because it's math based, after all, how hard can the math be?

Well my friends, on retrospect I could welcome programming projects, I have been reviewing and learning math, math, math for the past 12 months. I think I am finally getting it, but only because of rote determination, by the sheer power of my fear of failure, I have been spending my evenings and weekends trying to know, and understand the material in the books pictured above.

From Calculus I am reviewing Integrals: Integration by parts, the number e and its properties, logarithms and logarithmic functions, Taylor Series, Fourier Series, Power Series, Trig identities.

From Signals and Systems I had to teach myself the Convolution Integral, something that I never saw my undergrad and something that was truly meant for computers to calculate, I don't know how on earth mathematicians knew these things before the age of electronics. Kudos to them.

From Probability and Random processes I realized that I am a math chump, an inferior being who can't grasp the simple concepts of combinations and permutations, who has trouble setting up probability densities and distributions. Random variables, Random functions, Random sequences and Random processes nearly took my sanity away last semester.

This semester looks more promising, since we use all the math in the foundation subjects to apply them and come up with working systems that transmit and receive information using electromagnetic fields, binary or M-ary signals. We learn about the signal to Noise ratio necessary to have a low probability of error. It's kind of rewarding to see how all the material comes together to make something do useful work. I never thought so much about something we take for granted on a daily basis. We expect cell phones to work, our laptops to get flawless wi-fi signals, our long distance phone calls to sound crisp and instantaneous. Behind all these things there were industrious engineers making things happen.

So I have been studying. I take a break every now and then, but I can't think of much else, just the family, the job, and the math.

I am glad I took this break though, after this a little more work and then put the kids to bed, and watch a movie with my lady.

Be good to each other guys.
