BEING  A COMPILATIONTHERE MAY  BE ERRORS

 Q1          IsChennai’s cost of living higher or equal to Bangalore's in terms 
of rent andother essential items?

A1           Prasanna Bhalerao I have someexperience in real estate deals. Sun

I haven't lived ineither cities (on a long term basis). But I think, 
considering all aspects,what i have seen during brief visits, and all hearsay 
things, Bangalore should be moreexpensive, probably by about 10% more. 

Basically it istypical demand vs supply. More people flock to Bangalore than to 
Chennai forall sorts of reasons. Naturally this will cause prices to inflate.

Mynote- House rent is at least 3 times more ingrated community areas.

Q2           What makes olive oil superior tovegetable oil for cooking?

A2           Martin Bayer Chef (1994–present)Fri

Olive oil tastes better than vegetable oil, which isusually soybean oil or a 
blend of soybean and other neutral oils.

Sometimes you wantthe flavor of the oil to shine through in a dish, which is 
where olive oil isthe superior choice. Sometimes you don’t, which means you’d 
be better off withvegetable oil.

If you are doing a lot of frying, vegetable oil is abetter choice, since it has 
a slightly higher smoke pointandwill stand up to high volume frying. You can 
fry with olive oilbut it’s kind of a one and done deal. It doesn’t stand up 
torepeated  heating a cooling and breaksdown quicker from use. You can get 
multiple uses out of vegetable oil, oliveoil, not so much so. Olive oil also 
imparts it flavor ontofried foods, which may or may not be desirable for the 
dish.

Neither oil iscompletely superior to the other. Just choose the right oil for 
the application

Q3           What is the difference between self-tappingand self-drilling 
screws?

A3           Loring Chien making holes in stuffsince 1970Mar 24

Tapping is theprocess of cutting threads into a existing but slightly 
undersized hole.

Drilling ismaking a hole where there was not one before.

So self tapping screw is used with a existing hole; itwill thread itself into a 
slightly undersized hole, cutting threads as it isdriven.

Self drilling screws have the ability to drill the holeand remove material from 
the core of the hole as it is driven; you will oftensee a vertically running 
flute to help remove material.



Here, a self -drilling s*c*r*e*w has a point that looks like atwist drill with 
a material removal flute, followed by threads to self- tap aswell.

Q4           Why haven’t USB cables replaced everyother cable, like Ethernet 
for example?

A4           Alec Cawley Software Engineer Apr 30

Firstly, USB has avery strong Master/Slave structure. It is designed for a 
controlling computer, the Host, totalk to a number of controlled Devices. They 
literally cannot speakuntil the Host invites them to do so. And Devices cannot 
talk to each other. Soit doesn't work well for multiple computers which see 
each other as equals.

Secondly, USB cables have to be short, especially athigher speeds. Lowspeed USB 
can probably go to 5 metres, but the higher speeds will only do about1m.

Thirdly, the USB protocol only allows for 127 devices.Generous for Devices 
connected to a single Host, buy too small for all but thesmaller offices.

Ethernet fixesall these problems. It is a peer to peer network which can have a 
vast numberof hosts. Simple cables can run 100 metres, specialised ones can run 
for miles.USB is very good at doing the job it is designed for, but it ishighly 
specialized for that job.

Q5           What are the uses of a lotus leaf?

A5           Lucia Garcia Worked at Hospitals11h

In some countries, such as Vietnam, China and Korea,lotus leaf has been used as 
a tea drink since ancient times.

Lotus leaf tealooks pale golden or honey yellow and tastes slightly astringent, 
but has a sweet aftertastewith a hint of floral aroma, which makes it a very 
alluring beverage.

In recent years, more and more people drink lotus leaf tea,and many people 
regard lotus leaf tea as a great herbal tea for weight loss.

Lotus leaf tea isan excellent source of nuciferine.Nuciferine has significant 
weight loss effect, can effectively breakdown fat and excrete it from the body.

Nuciferinecan also form a protective film on the intestinal wall, thus 
preventing fatabsorption and preventing fat accumulation.

As a health caretea, lotus leaf tea can also lower blood pressure, lower blood 
lipids, andlower cholesterol, which is very beneficial to the health of 
cardiovascular andcerebrovascular. Lotus leaf tea does not have any 
sideeffects. You can buy lotus leaf tea online at an inexpensive price.

Q6           If Earth has a round shape andsuspended in space, why is its 
liquid content like water not pouring out of it?

A6           Claire Jordan Degree in biology andfolklore; programmer, shop 
owner, secretary on newspaper May 8

Because “down” is towards the centre of the nearest largeplanetary or stellar 
body, and the nearest large planetary or stellar body tous is the one we’re 
standing on. 

Down istowards the centre of the Earth. Pour water out of a container and it 
fallstowards the centre of the planet.

Q7           What is dosa called in Konkani? Whatare the different dosas cooked 
in Konkani households?

A7           Anup V Shanbhag Native Konkanispeaker in North Canara dialect. May 
15

Dosa is known as pŏḷo (पॉळो, ಪೋಳೊ) in Konkani. Dosa is one of the most popular 
breakfastitems in Konkani households. It is usually eaten withchutney, ambatt 
(gravy), batat bhaji (potato bhaji), sukkhe (stir fired dish)or fish curries.

I have listeddifferent types of Dosas cooked in Konkani homes below. I have 
written from theperspective of Canara Konkani, however some are found among all 
Konkanis.

Uddha polo (ಉಡ್ದಾ ಪೋಳೊ, उडदा पॉळो)

This is the mostcommon type of dosa made of urad daal.

Pan polo (ಪಾನ್ ಪೋಳೊ, पानपॉळो)

This is same as neerdose in Kannada. Patal god (liquid jaggery) is a good 
combination with this.

Doddak (ದೊಡ್ಡಕ್,दोड्डक)

A thick dosa madeof urad daal with sesame seeds. Doddak is so filling that 
eating only one isenough for breakfast.

Kande polo (ಕಾಂದೆಂ ಪೋಳೊ, कांदें पॉळो)

Onion dosa, same asit done all over South India.

Nanchane polo (ನಾಂಚಾಣೆಂ ಪೋಳೊ, नांचाणें पॉळो)

This is nothing butragi dosa and is one of the more recent additions to the 
list of Konkanibreakfast recipes.

Surnalli (ಸುರ್ನಳ್ಳಿ, सुरनळ्ळी)

A yellow coloredsweet, fluffy and porous dosa made from yellow cucumber or 
watermelon rind orash gourd.

Ponsa polo (ಪೊಣ್ಸಾ ಪೋಳೊ, पोणसा पॉळो)

Dosa made withjackfruits, eaten in summer season when jackfruits are plenty.

Dosne polo (ದೊಸ್ಣೆಂ ಪೋಳೊ, दोसणें पॉळो)

Dosa made withshredded leaves of hibiscus plant, usually eaten in monsoon 
season.

Sanna polo (ಸಾನ್ನಾ ಪೋಳೊ, सान्ना पॉळो)

A spicy dosa madewith onions, cabbage and dill leaves. It is usually eaten at 
lunch as a sidedish with rice and dalitoy (konkani daal).

Q8           Are bees the only way to make honey?

A8           Alexander L lifelong Californian May15

By definition, honey is produced by bees.

It’s not becausebees are the only creatures that can produce such a substance, 
but ratherbecause, in order tocall it “honey”, it has to be made by bees.

If it’s made byhumans, it’s called “syrup” instead.

Q9           Why don't wind turbines usually have4 blades?

A9           Andrew Forrest Chief Engineer atSolstad Offshore (2005–present) 
May 5

Essentially two reasons, efficiency and resonant loading.

In terms of turbineefficiency and drag, theless blades the better, with a 
single blade being the ideal on paper.In fact there have been single blade 
prototypes constructed with the view tomaximising this aspect.

A single blade hasthe least amount of drag but it does introduce balance and 
resonance issueswith the lone blade having a cyclic pulse effect on the hub 
bearings. Thisarises from the large difference between the wind force applied 
at the top ofthe stroke (maximum force), and the bottom of the stroke (where 
the wind isoccluded by the support tower).

If one blade is best for a lift based design, then surelya two bladed design 
would be best for balance then?Unfortunatelywith two blades your resonance 
effects between top and bottom positions of theblade is exacerbated even 
further with a significant rocking couple putting alarge load on the bearings 
and blades themselves.

If you fit fourblades, you have the same situation with regards to resonance as 
two blades,but with a resonant frequency twice that of a two blade unit. The 
obvious sweet spot then is to fit three blades, which keeps the numberof blades 
to a minimum (and thus energy sapping drag), while at the same timebreaking up 
the strength of the rocking couple that the system is exposed to.

Q10         What are some things that happen onlyin India?

A10         Sairam Ramasubramanian Works atStandard Chartered India Updated 2y

Philosopher’s town.

Recently, I had togo on a road trip to Ambur, a town that is around 150 kms 
from Chennai. We wereattending my best friend’s wedding.

It is peak summerin our part of the world and that day was a merciless 46 
degrees Celsiusburning every living and non living things.

We stopped for lunch at a highway cafe near Kanchipuramand my wife 
inadvertently kept the car key inside the boot and locked it.The spare key is 
at my home, some 100 kms away from that place and we weregetting really late 
for the function we were attending. I tried calling ToyotaService and they 
advised that it will take a while to get there. While I was atthat, just by 
looking at my facial expressions that gave away my helplessness, a few people 
gathered around thecar trying to help me. 

The restaurantmanager called their electrician, a few of them tried to Jimmy 
the lock and one mechanic who was on the way hometo have lunch stopped and 
started attending the car, not minding the hotweather. Eventually the boot lid 
was opened by pushing the leverthrough a small opening that is there underneath 
the car for some otherpurpose.

Well, the point is not about how everyone helped whensomeone was in trouble. 
That’s a nice quality mypeople have and I will not say it is specific only to 
Indians. I have seen thisnature among a lot of others nationalities too.

But, almosteveryone said one thing - “May be the god prevented you from some 
danger by stalling you here.So, just don’t mind about getting delayed”. This 
was told by almostall the people who helped me that day. This actually made 
absolute sense to me.

When things does not go as per the plan, Indians have thetendency to surrender 
themselves to the greater plan of the almighty.And that attitude helps us a lot 
in our day to day lives.
