I had been to technical seminar yesterday. With my experiences from the past so far, I have come to conclusion that more than half questions you can safely classify as redundant. Sometimes they are so redundant that they as off the topic by miles.
Then there are few that can be classified as questions related to the common sense, or related to the very basic knowledge. These types of questions are the most humorous of all.

Yesterday one guy (presumably from a big company working in embedded systems) asked: Do you have external interrupt on the processor?
A; Yes, 16 external interrupt to the processor.
Q: Do I have to poll to receive them?

The example is a bit technical; but to clarify interrupt can never be polled. Interrupt mechanism, by the name or philosophy of operation itself, is contradictory to the polling mechanism.

Hail stones.

Three years back the weather was never so unpredictable, Bangalore was never so hot. Sitting in the air-conditioned office through out the day never really gives a true picture of whatever is happening outside, but still, during the week-ends mercury used to lie around readings that would not be make one uncomfortable with the help of fans.

These days weather gods are not that happy. As the day progresses the temperatures are increasing making outside life more and more uncomfortable but the meter inside the office keeps telling the same temperature over and again - 22 degrees. With the help of internet computers keep telling the outside temperatures every hour or so, or whenever I care to run down the stairs for a cup of coffee.

As evenings approach, the angry weather swings, it cools down at the rapid pace. By 6pm the temperature has come down considerably, and by 6.30 the summer season itself has gone somewhere, it has started raining. Just as an pattern over previous couple of years, whenever it got very hot, it has rained in the evening.

Yesterday it went one step further, like emulating weather in the mountains. It was hot in the afternoon, rained in the evening, and showred hailstones in the late evening/early night. On the backdrop of dark night (courtesy power failure), It had become white everywhere, the lawn was covered with hail stones. What a wonderful sight it was.

Around a decade back

I still remember, I was in school that time in the 8th standard when I heard of computers first time. We had option between computers and drawing in that year and almost all of us had taken computer course. Only once our teacher had taken us to the computer lab. It was an air-conditioned lab. We were awestruck, as I had never been to an air-conditioned room before and nobody out of my friends had seen a computer before. We removed footwear outside the lab out of fear that some virus may attack computer. I guess that time even our teacher did not knew which virus actually attacks the computer. So there, we had removed our tiny shoes outside the lab and we stood in semi-circle around the lone computer that was in the lab. Everybody was pushing each other around in order to get closer look. Our teacher opened ms-paint. He then showed us how to draw something on computer. It looked like out of the world that time, drawing without pencils, sketch-pens, eraser and sketch-book. First of all seeing a computer itself was a big thing and then ability to do sketching on a computer was even big thing. After our teacher had drawn whatever looked like a tree, we thought we would have homework to draw something similaron a computer. We pushed each other around in order to use the computer, but our teacher ordered all of us to go back to the class. We used to boast about our teacher. My teacher is a master in computer. He can draw sketches. He operates computer very fast. And none of my other friends believed that that time.

I had not even thought that time that someday I would work on a computer, or own one. And today when we have three laptops in our house and probably two more on their way to our house, it somehow doesn't feel that we know a great deal about computers. It has no longer remained the thing of awe, instead has become a necessity. Your eye-sight, your energy, ration, medical, grocery bills are all now told by computers.

Even this post would not have seen the light of day without a computer.

Feeling sleepy?

Yesterday, since morning I was fighting hopelessly against sleep. I tried tuning to radio, gulped cups of coffee, browsed internet for some time, talked with friends but nothing seemed to be working. Finally I decided to call it a day and have sound sleep in the comforts of my home. But to my dismay, the very sleep which had troubled me for long in the office had gone somewhere far off.
