Climate change due to tilt of earth axis

undertowsam — Sat, 01 Jan 2011 07:07:56 +0000

Change in earth axis and constant loss of sun’s energy has certainly affected the earth climatic condition. According to scientist at NASA, the catastrophic earth quake of Chile in 2009 has tilted the earth axis. The rotation and revolution of earth can be affected due to change in axis which results change in climatic condition. The earth is more cooler during winters and more hotter during summer can be due to changes in earth axis and gravitational power of sun. The figure below shows the probable changes of earth revolution. The change is denoted by red oval shape.

Changes in Earth Revolution

Changes in climatic condition have resulted in change in vegetation. The changes in climatic condition have affected the Himalayas and its vegetation. The Everest, world highest pick has received lower snow fall in 2010. The real reason behind low snow fall has not yet been found but it can be due to change in earth axis or global warming.

How to increase SWAP memory in Ubuntu 10.04?

undertowsam — Thu, 01 Jul 2010 12:04:20 +0000

While installing Ubuntu, sometimes we forget to allocate swap memory. This mistake can degrade the performance of the system. It is advice to allocate swap at the beginning. But its not a major problem since we can allocate swap memory indirectly. SWAP memory should be double of the primary memory. If you have 512MB of RAM then it is wise to allocate 1GB of swap memory.

Here are the steps to increase the swap area in you Linux Machine

1. To create 2GB (2048MB) swap file (1024*2048MB = 2097152 block size)

sudo dd if=/dev/zero of=/swapfile1 bs=1024 count=2097152

2. set up linux swap area

sduo mkswap /swaparea1

3. Activate /swaparea1 swap space immediately

sudo swapon /swaparea1

4. Reebot and open gedit

sudo gedit /etc/fstab

5. Append following line to file

/swaparea1 swap swap defaults 0 0

6. Reboot and to check

sudo free -m

Virtual World

These days growth in technology is highest of all time so there is no doubt one day technology will replace us. So imagining the world after technology concurs.

People will forget that there exist Kilometer or Miles, they start talking on hop count. Jack is 4 hop away.
The quality of road will be measured in bandwidth. People will say- the bandwidth at Pokhara is too less rather than the road is narrow at Pokhara.
The speed of car will be measure in Mbps, Gbps rather than Km/s, miles/s. The speed of fastest car on earth will be 564 Tbps.
The car will renamed as packets. The lightest car will be Datagram.
The neighbour will turn to be nearest routers with administrative distance of 1.
The richness of people will be calculated in processing power. The total worth of Bill Gates will be 66GHz.
There exist a private highway for people who can afford through tunneling of channels (or VPN).
The software like anti-AIDS, anti-theft, anti-terrorist will be developed. Patches for Bin Laden will be frequently release. America will be venerable due to Bin Laden. And there is no patches for AIDS.
The capitals will renamed as access-point. The access point of England is London.
The origin of people will be Mac, Dell, Compact rather than Aryan, Negro or Mongolian.
The Doctor will specialised on different vulnerabilities and start saying I am ECH or RedHat or MCTS certified, come on I can fix your problem.
The Police Check Post will be replace by Firewall. We can see “Go through Firewall to enter into the country” written in the hoarding board ahead of Firewall Post.

And finally my friend MILAN will find patches for human stupidity.
