Can we run seti@home on Macbook air 11.6" ? ( model A1465 )
This Macbook air doesn't seem to has a ventilation fan.
Will running seti@home on it causing too much heat? possible shorten the life of the CPU?
2) Questions and Answers : Unix/Linux : Is it possible to run Seti@home on live Ubuntu or live Fedora DVD? (Message 1737390)

My laptop doesn't has any harddidsk.
I just insert a live Ubuntu DVD and boot from it.
Tried install seti@home but so far no success of running the application.
But there is no problem of install and running other applications like google-chrome-browser and download manager.

Latest news (6 March 2015):
Astronomers believe mysterious signals - previously dismissed as stellar bursts - are coming from an Earth-like planet.
The Gliese 581d planet has conditions that could support life, and is likely to be a rocky world, twice the size of Earth.
Signals from the planet were initially discovered in 2010, but last year dismissed as noise from distant stars.

Lockheed Martin Claims Breakthrough on Fusion Energy
Oct 15 (Reuters) - Lockheed Martin Corp said on Wednesday it had made a technological breakthrough in developing a power source based on nuclear fusion, and the first reactors, small enough to fit on the back of a truck, could be ready for use in a decade.

Look similar to the Mirror Fusion Test Facility (MFTF-B) project that was canceled by the Reagan administration Department of Energy during 1986.
So, Lockheed Martin is going to re-start the mirror fusion?

Story of MFTF-B:
In all it took nine years to build MFTF-B machine at a cost of US$372 million. On 21st February, 1986 staff and guests gathered for the official dedication ceremony. The Secretary of Energy, John Herrington, had traveled over from Washington along with other DoE staff and he commended the Livermore team for their work. But it was not the joyous occasion everyone had been expecting.
The political climate in the mid 1980s was very different from a decade earlier. Ronald Reagan had come into the White house in 1981 and had aggressively cut public spending. The high oil prices and frantic search for alternative energy sources of the 1970s were now just a memory. To the Reagan-era DoE, funding a second type of fusion reactor just to provide competition for tokamaks was an expensive luxury. So the day after congratulating Livermore on its achievement, DoE shut the doors on MFTF-B without ever having turned it on. A few years later it was dismantled for scrap and to this day the scientists, engineers and technicians who spent years working on the machine do not know if it would have worked. (from the book "A Piece of the Sun" by Daniel Clery)

And this bit made me wrinkle my nose in distaste...

McGuire said the company had several patents pending for the work and was looking for partners in academia, industry and among government laboratories to advance the work.


...even though I concede that patents and intellectual property rights may be a necessary evil (in the sense of recouping costs and getting a return on investments) ... they've become a blockade to further research in the past...

If any self-proclaimed amateur scientist trying to do hot fusion experiment at home and created a portable fusion reactor...he is going to infringement of Skunkworks's compact fusion patents?...Yes?...No?

Carl Sagan's "Cosmos":
"With a continuous 1 g acceleration, after one year in space we would be traveling very close to the speed of light [(0.01 km/sec2) x (3 x 107 sec) = 3 x 105 km/sec]."

Correction to the calculation above, should be
[(0.01 km/sec^2) x (3 x 10^7 sec) = 3 x 10^5 km/sec]

3 x 10^7 sec is 30,000,000 sec (1 year = 31,536,000 sec )
3 x 10^5 km/sec is 300,000 km/sec (light speed = 299,792 km/sec)

Is interstellar space travel possible?
Well, after reading Carl Sagan's "Cosmos", I believe it is possible.

Carl Sagan's "Cosmos":
"If we lived in an interstellar spacecraft that could accelerate at 1 g, we would find ourselves in a perfectly natural environment. In fact, the equivalence between gravitational forces and the forces we would feel in an accelerating spaceship is a major feature of Einstein’s later general theory of relativity. With a continuous 1 g acceleration, after one year in space we would be traveling very close to the speed of light [(0.01 km/sec2) x (3 x 107 sec) = 3 x 105 km/sec]."

But, where can you get the energy to push a spaceship at 1 g acceleration for one whole year? The answer is, nuclear energy, whether it is deuterium+tritium or uranium.
Human's modern science and technology started only about few hundreds years.
If there are alien species out there who are science and technologically thousands or even millions of years more advance than us, they might already have the technology to built rocket engines that powered by nuclear energy.

For a space ship that travel near light speed (80%-90% maybe), interstellar space travel from nearby star system takes about 10 to 50 years(planet time), but on space ship time it is only about a few months.

So far NASA had spent nearly US$200 billion on space shuttle programme.

Just wondering, isn't it more useful if the money is spend on new renewable energy research. Example more funding for ITER project? More funding means higher chance of success? And Shorter term to achieve the success?

The first duetrium-tritium reactor might be too expensive for producing electricity, but as more research is carry out, later improved design reactor might one day become economically viable for large scale electricity generation.

Just like the first computer was very expensive but as the technology improve, the cost of computers have decreased tremendously.

The desktop i am using is constructed from Intel mainboard DH67CL and the CPU is Intel I5.
Installing Mac osx (10.8.2) is quite straight forward by following instruction in

But for network, i use product from Edimax because their product come with driver for Mac.

This desktop is now running seti@home but it utilise only one CPU although the 'Activity Monitor' showing there are 4 CPUs in the system.

Am i right of saying this:

"When my pc infected with malicious software (sent by the hacker),
and the hacker take over my pc (or my pc got hijacked by the hacker).
It is like the hacker sitting infront of my pc.
He can do what ever he any files/pictures he like.

But the person who face the consequences is me because it is my pc and the internet account is under my name. The hacker is totally hidden, i don't know who the hacker is, and the ISP also unable to trace who the hacker is?

17) Message boards : Science (non-SETI) : Travel speed of distant galaxies compare with nearby galaxies. (Message 1183018)
Posted 5 Jan 2012 by Profile Cheng Fan Soon
When astronomer observe that quasars happen only in very distant galaxies, they made a conclusion:
"Because of the great distances to the furthest quasars and the finite velocity of light, we see them and their surrounding space as they existed in the very early universe."

And now the astronomer's observation is that 'high speed galaxies' happen in very distant galaxies.
Can't they make the same conclusion on the 'high speed galaxies'?

Posted 4 Jan 2012 by Profile Cheng Fan Soon
From what I know, distant galaxies travel with higher speed compare with nearby galaxies.
Distant galaxies also younger compare with nearby galaxies.
Our universe is about 13.75 billion year olds.
When we see galaxies which are 13 billion light year away from us through telescope,
the galaxies we see are actually only 750millions year olds.
and they travel at higher speed compare with (example) a nearby galaxy Andromeda, and Andromeda is about 13.5 billion year olds.
Isn't this show that as galaxies getting older, it's travel speed will also gradually decrease?
19) Message boards : Science (non-SETI) : The effects of time dilation on interstellar travel. (Message 1180580)
Posted 25 Dec 2011 by Profile Cheng Fan Soon
My thought is: "Time dilation is actually good for interstellar travel"
Say we have a space ship that travel at 50% of light speed.
To travel to nearest star Alpha Centauri which is about 4.3 light years away.
This space ship will take 8.6 years (earth time) to reach Alpha Centauri.
But on the space ship because time slow down, the people on the space ship might only get older one year.

My view is, it is possible to push space ship to say 50% light speed if we find a way to harness the energy from fusion power with "fusion engine"

Some advance alien species out there might already master the skill of harness energy from fusion power.

Some people say that a space ship moving at near light speed, an asteroid size of a 1cm diameter colliding with the space ship will cause total destruction of the space ship. My view is: "the chance an asteroid colliding with the space ship is very low...almost 0"

From where I got this idea? well....Discovery channel and History Channel's space programme,, some text book about space.

There are 51 star systems that are within 16 light years radius from Earth.
With a space ship travel at 50% light speed, travel to these star systems and back to Earth is still within a reasonable time frame.

Alpha Centauri, 4.3 light years from Earth
Barnard's Star, 5.96 light years
Wolf, 7.8 light years
Lalande, 8.3 light years
Sirius, 8.6 light years
Luyten, 8.7 light years

20) Questions and Answers : Windows : How to increase the anti-vrus anti-malware power of your windows pc (Message 1179204)
Posted 19 Dec 2011 by Profile Cheng Fan Soon
Just wondering how you guys handle the internet security issues (How to protect your computer from unwanted viruses, worm, Trojan, malicious-ware).
No one want his/her computer being hijacked and become one member of the botnet unless it is for experiment/investigation.

I know there are website talking about this topic, but a big question in my mind is:
"Will a good Internet Security Suite able to give me 100% protection?
That means after I install the Security Suite into my Windows, I can be sure that my Windows PC will never be hijack by the hacker to become a botnet machine? (assume i don't simply click those link that come into my email mailbox)"

Although a firewall can provide some protection, but most of us home user will just use a basic firewall that come with the router - with default setting.
Will an enterprise class firewall able to give me higher degree of protection? (assume i just use the default setting of the firewall....not everyone of us know how to configure a firewall)

Often read in some website about "Why Windows so prone to virus attacks"

Although this question has nothing to do with running Seti@home.
But because of the worrying of the viruses/malicious-ware/botnet infection, I don't connect my Windows laptop to internet and thus unable to run Seti@home.
While for the other 6 PCs that installed with Solaris and Fedora, I have no worry to connect them to internet and run Seti@home.
