Solar water still

Water crisis is approaching all of us very soon. Already some where in Africa people are killing each other for water

So we need to find a way  of conserving water. Water still is a machine which converts saline or dirty water into drinking water by distillation. Yes, we in India have large coastlines, and if necessary we can use sea water.

But the costs are very high and are not affordable to rural poor. The people who need it most.

An entrepreneur Garbiele Diamenti has designed a solar still which does not need electricity or any expensive parts.

  This still is called EliDomestico. It works like this.

" Pour water into the spout at the top and walk away. Thanks to the circular top, no matter the time of day, it's hit by maximum sunlight. The heat turns the water into steam, which travels down through a nozzle and condenses against the lid of the bowl at the bottom of the still. At the end of the day, the bowl is full of safe, potable water."

The still is made fr…

A nayi soch

I have been watching some TED talks for the last few years. No, that has not made me a great scientist or an artist. But as long as I am watching them, I feel pure happiness - happiness which is not encumbered by greed, desire, guilt. It is a happiness of hope - for the humankind.

So today when Ted talks India is being telecast in Star Network, I watched it. And I am happy, I watched the program. The speakers were, Shubhendu Sharma who creates forest within cities, in your backyard, and a scientist  from California who has made microscopes from papers, another engineer who is creating ink from pollution among others.

So the idea is that the world is not filled with all bad people. There are good, intelligent people who strive to make our country and our world a better place. And TED honors these people and gives them a platform to share their ideas.

So do not miss the show - Ted talk India - a nayi soch.

I remember I had blogged about Satyameva Jayate too.

Anyway we watch the same ol…

Grand unified boot loader

As is my habit, I was tweaking my ubuntu laptop and I deleted one unused partition. Then I continued working on the system.

After I while I turned off laptop and went to TV. Coming back, I realized my system won't boot. Leave along booting, it was not even showing boot menu - the grub menu. Instead it was going to some grub rescue.

Grub is a program which shows the OS options when you switch on the system. Yes, it is called grand unified boot loader. But currently it was not able to find the partition.

After some googling, I came to know that I should find out the partition in which grub is present using ls command, then insmod something called "normal" and then execute normal command.

And it worked, I did get back my boot loader. And hence could boot the system.

So I keep thinking about this, many people like me may post the question about grub rescue, but who has the time, inclination and dedication to answer these? But there are. There are plenty of good Samaritans w…


I hear this Kannada song in Soundcloud, which has lines

   anu rEnu traNadalli paripUrNanu nInu
   kshaNakshaNake avaguNagaLa kukarmi nAnu

which roughly translates to
   you are perfect in each and every molecule
   but I am full of defects and am a bad person

Some how, the song touches my heart. By the way it is a devotional song and I can not remember how it starts.

So this perfect God has created men and women in his form and he made some of them like light, some of them like dark, some of them speak one language, some speak another language.

May be he gave one religion to some people, another religion to some other people.

So that people can hate each other and in some cases kill each other?

Doesn't sound right!

But this particular grouse of mine is not related to aptrard, siculars or any other adjectives here. I have gone global. I am watching this serial "Shots fired" and being troubled by its storyline.

I went out

I went out today because I had some work in the bank.

Then? Then nothing. I went and finished my work and came back.

Why am I telling you this? I thought it was important - me going out. Because everyone around me thought so. So I thought that too.

Or may be they are wondering how do I still manage to get outside the house in spite of their slandering and mean intimidating. Is it?
