Robotic Takeover

Years ago, I read this fictional story by Marshall Brain called Manna. It talked about the robotic takeover of a fast food chain by an intelligent system.

Marshall Brain, as you may know, is the founder of HowStuffWorks.com and a well known speaker, teacher, writer etc. Although he wrote Manna as fiction, he was so certain that it was the way of our future that he actually patented the system he described (if memory serves). Of course, he was right. I just got this link from a friend about how fulfillment centers work — how do you get the same-day or next day delivery on all those mountains of things that you order from the Internet? Here is how. It is astonishing how similar this scenario is to what Marshall Brain described in Manna.

Death and Grief

Some recent events have prompted me to revisit this uncomfortable topic — why do we grieve when someone dies?

Most religions tell us that the departed, if they were good in life, end up in a better place. So grieving doesn’t make sense. If the departed were bad, we wouldn’t grieve any way.

Even if you are not religious, and do not believe in an eternal soul, death cannot be a bad thing for the dead, for they feel nothing, because they do not exist, which is the definition of death.

Fields Medal – First Woman

Just read the news that Prof Maryam Mirzakhani won the prestigious Fields medal (the equivalent of Nobel prize in Mathematics). She is the first woman to ever win the prize. First of all, congratulations to her. Coming from an Iranian background, being a woman, I’m sure it must have been hard for her.

Women seem to have difficulties in quantitative fields — we see this everywhere. The general belief is that compared to men, women are more creative and intuitive, but less analytical. They take in the world as a whole. Theirs is a romantic understanding, concentrating on the immediate appearance and values of the objects around them. This mode of understanding is to be contrasted with the analytic, classical understanding of men, who seem to mentally divide things in smaller, manageable chunks and drill down to the underlying forms to come to grip with world around them. In giving this description, I’m trying to paraphrase what Richard Pirsig said in the opening chapters of Zen and the Art of Motorcycle Maintenance. The analytic mode of understanding lends itself better to quantitative fields like mathematics, and hence the paucity of brilliance among female mathematicians.

Stating the reason that way doesn’t really explain anything. We have to wonder where this gender difference comes from. Continue reading

Back to Blogging

As you may have noticed, I haven’t been writing much in the last couple of months. It was because of one of my regularly scheduled writer’s blocks. When I’m blocked, I usually find other things to do, and convince myself that they are really important and urgent. One such thing this time around was a revamping of my blog backend. The original design was dated, and it really needed an upgrade. Or so I told myself and worked on it for a few weeks. If you are reading this post, you can see the fruits of my labor. And I hope you like it.

High Performance Blogs and Websites

Do you have a website or a blog and feel that it is getting bogged down with heavy traffic? First of all, congratulations — it is one of those problems that webmasters and bloggers would love to have. But how would you solve it? The first thing to do is to enable PHP acceleration, if your site/blog is PHP based. Although it should be straightforward (in theory), it might take a while to get it right. You know what they say — In theory, theory and practice are the same. In practice, they are not. Acceleration, however, is a low-hanging fruit, and will go a long way in solving your problems.

Once you have extracted all the mileage out of the accelerator solution, it is time to incorporate a Content Delivery Network or CDN. What a CDN does is to serve all your static files (images, style sheets, javascript files, and even cached blog pages) from a network of servers other than your own. These servers are strategically placed around the continent (and around the globe) so that your readers receive the content from a location geographically close to him. In addition to reducing the latency due to distance, CDN also helps you by reducing the load on your server.

Learn to Play Blackjack

Here is an online Blackjack game that will teach you how to play it. If you don’t know what to do, just ask the program! This post hopefully teaches you sound strategies in playing Blackjack. But you should know that even with the soundest of strategies, Blackjack is a losing game. The house always holds a small edge. The best any strategy can do for you is to increase your staying power — the time it takes you to lose your shirt.

Sad Movies

I found something weird. People seem to like sad movies — tear-jerkers. But nobody likes to be sad. I mean, you watch great tragedies with genuine sadness, and then go around saying, “What a great movie!” If whatever happened in the movie really happened to you or somebody you knew, you wouldn’t say, “Wow, great!” Why is that?

I think a good answer is that such depictions in movies let you experience the emotional intensity with no immediate physical (or even emotional) danger. If you were actually on the Titanic, you would at least have taken a cold dip even if you survived. But watching Kate Winslet and Leonardo DiCaprio battle for their lives probably lets you experience their fear and pain from the comfort of your armchair, with popcorn and soda to intensify the feeling.

Internal and External Successes

Success can be internal or external. External success is easily measured in terms of money and material possessions. The internal one is measured in terms of less palpable yardsticks, like happiness, peace of mind etc. External success is related to extrovert qualities, like articulation, and depends on what others think of you. The internal one, on the other hand, depends on what you think of yourself. It is made up of things like duty, honor etc. Confusing one with the other leads to misconceptions like identifying money with happiness, for instance. You need one for the other, but they are definitely not the same.

How to be Successful in Life?

When I talked about the dimensions of success, I used the word dimension with an ulterior motive. I want to define success for you in a formal way. You see, an entity that has many dimensions is a space, similar to the three dimensional space we live in. When we have such a complex multi-dimensional space to define success in, we have to apply some good techniques from physics to do it right. Don’t worry, i am here to help.

Dimensions of Success

Money is only one dimension along which success can be defined. There are many others, such as sports, music, art, acting, politics, professions and even more abstract things like articulation, soft skills, philanthropy, wisdom, knowledge etc. Excellence in any one of them can be thought of us success. Success is easy to spot — look at any one of the celebrities and ask yourself why you know them. The answer is usually one of the dimensions of success — and fame its byproduct.

Excellence in any field can translate to money, which is what Eddie Felson in the Color of Money tells the younger pool player. This transformability often leads us to mistake money for the measure success, which, by the way, is the theme of the afore-mentioned movie. Towards the end of the movie, when Felson realizes that there is more to life than money, he says, “I just want your best game.” Ability to hang with the best game anybody can dish out in any field is excellence; and it has to be reckoned as success. This excellence is probably what the ancient Greeks called arete.
