Recently we have been looking around for a microwave oven since there have been many advertisements for microwave ovens from LG, Samsung, IFB whirlpool etc. After looking around it seems that the microwave oven from bajaj is pretty good considering its cost of around Rs. 5000/- . We mainly use the oven to heat up food like puffs etc bought from the bakery and sometimes rarely to bake cake.
Only after buying the microwave oven did we notice that it is not good to put metal vessels inside the microwave oven . Even some types of glass vessels cannot be used in the microwave oven.

pressure cooker
In Kerala, pressure cookers are usually used to cook idili, rice, meat, vegetables for sambar etc.
In our house we recently bought a new prestige pressure cooker. The older one also was a prestige pressure cooker which was around for a very long time .
Spare parts seem to be readily available. The only thing that has been replaced from time to time is the gasket. Here we take the old gasket to a shop in Chalai near east fort, and the shopkeeper gives a new gasket by comparing the size with the old one.
Other brands commonly available seem to be Hawkins, Premier pressure cooker etc

cable vs dth service
We had been using cable tv from asianet for many years. Initially it was for one tv and the cost was around Rs.180/- which was later increased to around 200 rupees.
They had introduced a set top box and digital service. But we did not change over to that.
Then we asked them for an extra connection for another tv which increased the charge to around 285 rupees. The only problem was that now and then some of the english channels like star world,some sports channels etc would just disappear for some months .
Then the age of dth channels came around with doordarshan dth service ddinews.gov.in, dish tv dishtv.in , tata sky tatasky.com airtel dth airtel.in, suntv dth sundirect.in etc.
We opted for tata sky in addition to the cable service .
We selected the package which consisted of most of the south indian channels, sports channels , english movie channels, music channels etc. In those days there were also radio channels from all india radio on tata sky.
But after a few days the radio channels just disappeared from tata sky.
Then one by one most of the sports channels and some other channels started to be moved into other packages for which the subscriber had to pay extra money. Most of the repackaging of sports channels would happen when there was some cricket match or series likely to be watched by indians.

driving test in trivandrum, kerala
Before taking the driving test you have to get a learner's license.For that you had to to take an objective test on the computer in the RT office. The questions that are asked correspond to important trafic signs, traffic rules etc. Books are available that contain model questions (usually in malayalam). But I was able to find an online version of the model questions in english.
After passing the test you are given a date after several weeks to appear for the driving test which consisted of taking a H test (driving the car in a particular pattern between iron stakes arranged in the shape of an H ; you go forward along one of the vertical lines of the H from bottom to top , then reverse to the middle , go in reverse along the centre horizontal line of the H , and then to the opposite bottom of the other vertical line of the H in reverse , then forward to the top of that vertical line , then reverse to the middle of the vertical line, then in reverse along the central horizontal line of the H and then in reverse along the first vertical line to the starting point. )and a short driving test on the road to test the gear shifting and hand signals.
My father taught me driving in his old petrol ambassador car (amby). But before going for the driving test, father advised me to take the test in a maruti 800 which is smaller and hence might make it easier to take the H test.
So we went to a driving school. The maruti 800 had the gear lever on the floor as opposed to the gear lever on the steering column of the ambassador I practiced on.
So we paid the driving school for a couple of hours of driving practice on the road and for practice of the H test using the Maruti 800.
The teachers at the driving school were very helpful. For those who had trouble taking the H test smoothly, they gave some pointers like stopping and taking the 90 degree turns based on sighting the iron stakes at certain points relative to the car's rear window quarter glass etc.
They also raise/adjust the fuel flow to the engine during idling for the test so that the engine does not shut down frequently in the hands of the amateur drivers.
Anyway the whole exercise was fun. I got the receipt of passing the driving test, but had to wait some days for the actual license since there was some problem with the printing machine in the RT office at that time
More details on the eligibility conditions , forms and documents , fee , requirements for renewal , international drivers licence etc is available at the kerala motor vehicle department website
keralamvd.gov.in .

problem on trapezoidal rule
evaluate integral of sinx from 0 to pi using trapezoidal rule with n=10
take a=0 b = pi, h = (b-a)/n = pi/10
break up the interval 0 to pi into subintervals of length h = pi/10
evaluate y = sinx at the endpoints
