Chandrayaan 2 launched by India using gravitational pull of Moon.

Who first thought of gravitational pull?

Chandrayan 2 was launched yesterday and it uses the same technology of gravitational pull that was used by Mars mission spcecraft, Mangalyan. The reported mission is stated by ISRO as under:

July 22, 2019 at 14:43 hrs IST from Satish Dhawan Space Center at Sriharikota on-board GSLV Mk-III. It will be injected into an earth parking 170 x 39120 km orbit. A series of maneuvers will be carried out to raise its orbit and put Chandrayaan-2 on Lunar Transfer Trajectory. On entering Moon’s sphere of influence, on-board thrusters will slow down the spacecraft for Lunar Capture. The Orbit of Chandrayaan-2 around the moon will be circularized to 100×100 km orbit through a series of orbital maneuvers. On the day of landing, the lander will separate from the Orbiter and then perform a series of complex maneuvers comprising of rough braking and fine braking. Imaging of the landing site region prior to landing will be done for finding safe and hazard-free zones. The lander-Vikram will finally land near South Pole of the moon on Sep 7, 2019. Subsequently, Rover will roll out and carry out experiments on Lunar surface for a period of 1 Lunar day which is equal to 14 Earth days. Orbiter will continue its mission for a duration of one year.

To understand the technique of using gravitational pull, this picture uploaded by ISRO explains better:

Gurdjieff thought about it much earlier.

Human programming: Are we ready to accept it.

Human programming is a fact for me but I do not think that everybody in the world is ready to accept it. More so, a large majority of people may not even understand it.  To understand the meaning of a word it is interesting to how different languages express it. But before that, lets understand what programming means in respect of computer program. Interestingly  when Woogle translated  it in Hindi it came out as “कार्यक्रम निर्माण” which if re-translated in English would be expressed as “creation of work/program”. Interesting?

Computer programming

The world programming is actually used in respect of computers. A program when in operation is also referred as “Algo Rythm”. The process of writing a computer program is called coding as it entails writing a long lines of codes in computer programming language. BTW the most popular language is called “C” and it’s latest version is called as “C++”. For example the first program which is taught to a beginner is how to make computer to give output of “Hello World” on screen. An example of the code: Continue reading

Why Income Tax department is promoting Microsoft and Oracle

Open source vs. proprietary software.

Govt of India has reiterated its policy to prefer open source software over proprietary software as part of its Digital India Initiative which is available here. However when it comes to application, different department behave differently. For over ten years income tax department forces citizens of India to use Window and Excel which is a proprietary software of Microsoft. Few years back they brought out an alternative and introduced a Java version of ITR as well. Though it does not work at all, never the less look at the choice. This time they picked Oracle proprietary version of Java. Why not pick open source? No body seems to know anything. Few months back, I had posted a grievance ticket too on their website. The officer who called up, knew nothing and kept on trying to convince me that I should borrow somebody’s window lap top to do the needful. Arrogance in stupidity.

Now I have asked following questions from Government of India under RTI Act

Kindly provide following Information under RTI Act:

1. Who is officer responsible for checking the functioning of ITR 3 Java Version, Please provide his name address and phone Number? If an entire team is responsible please provide the details of team leader.

2.If the aforesaid Officer is in the service of Govt. of India, please provide the name, designation, address of the disciplinary authority over him.

3. What is policy of Income Tax department about using open source software ? If no policy has been formulated please do state so. Continue reading

Google Chrome hangs Linux Mint 17 Quiana

It appears Google Chrome has some bug.

It hangs and stalls Linux Mint 17 a.ka. Quiana.

More the tabs, more the problem.

This web browser is supposed to be faster but right now it has become pain in all the wrong places.

It takes whole system down if more than four tabs are open.

I have updated the Quiana to the hilt but no help.

What is the option?

I was thinking of switching to Mate version but it is quite apparent now, with co-incidents, that Chrome is the real problem.

I have to wait for solution. Share if you have any.
