Silent night, Startling night.....

I was all alone.My parents had gone out to buy provisions.It was relatively cool so no fans were on.I was completing a school project, while listening to music on my iPod connected to a 5.1 channel home theatre.The home theatre is not a high end model or anything but has 4000W P.M.P.O, which is more than enough for me.I attached no external amplifiers or such.
I was listening to Daddy Yankee's song 'Rompe'.For those who don't know the song-towards the end, it fades with some people saying 'who's this?'.I knew the next song was gonna be bad so I went near the iPod, ready to change it.The song faded completely, or so I thought.
Suddenly, I heard someone say 'who's this!' distinctly to my left behind me!!
I spun around, REALLY startled.I thought someone was outside and said that to scare me!Nonetheless, I cautiosly opened the window and looked outside with my flashlight.Nothing.I thought about it, and decided to play the last few seconds of the song.The usual 'who's this' played and faded.Then, distinctly louder but not enough to be heard if any other noises are present, was the real culprit-the last 'who's this' in the recording.It was placed SO strategically- right behind me!!!
I was so focussed on completing my project that I did'nt even consider that the speakers could have played it!!!

Digicam corrupted?Do not fear!

I had this digital camera which got messed up pretty bad, to say the least.I tried many apps to try and get the pictures out.One was a stupid demo version of a software that costs $69.It located the pics, but said I could only retreive them once I buy the full version!
I was furious.I later looked out for good freeware.
Thats when I got PhotoRec.
I downloaded the thing easily[just some 1.2 or 1.5MB!]I scanned the camera with it.It not only found the same photos as the demo one, but also more than the other!!![Ones that I had erased on purpose!]
PhotoRec is good.I give it my recommendation.In case you're planning to search for a download on Google though, it may take some time.Most links are just descriptions of it.So I decided to give u the link to the site which I got it from-
www.artplus.hr/adapps/eng/downloads.htm
If something goes wrong though, DONT put the blame on me!Read other reviews about it, then decide whether it will suits your needs or not.
Happy recovering!!!

Could You Tell Me The Clock?

I bet a lot of you still look at the clock rate of a processor for comparison between two different processor families,even between Intel and AMD.
Think about it-what is clock rate?
It is the amount of calculations a processor can perform in a given time.But it is useful only when comparing processors of the same families, say between two Athlons, etc.That is-
an Athlon x2 with 3Ghz will be about twice as fast as one at 1.5Ghz.But you CANNOT say that a 3Ghz Athlon x2 is twice as fast as a 1.5Ghz Core2 duo.

Let me demonstrate like this-
Let us take two kids of the same age, say 10 years.If kid1 can finish 20 mathematic calculations in a given time and kid2 can only complete 1o similar calculations in the same time-span, we can conclude that kid1 is twice as smart or fast than kid2.
But by the same token, a 20 year old man who can complete the same calculations as kid1 in the same time is DEFINITELY not as fast or smart as kid1!!!! See?
Or put it this way- Pentium D may be able to do 3 billion addition problems in a second, so I suggest you imagine that C2D can perform1.86 billion algebraic problems in a second!

If you dont beleive me, then tell me how a Core2 duo at 1.86Ghz can perform much faster than a Pentium D at 3Ghz??
Core2 duo is the kid,Pentium D is the man.[of course, not for real though!]
Got it now?

Smilies that make your system cry!

I bet a lot of you are used to the crazy ads that pop up everytime you visit an unknown or questionable website.They usually go like-"You are the 999,999th visitor of our website.Click here to claim your prize!".They really could fool u.

Chances are,you would already know such ads well enough now to be fooled that easily.Then again, ads get more tempting.

I bet you use some kind of instant messaging service.Be it Yahoo,Skype whatever.You usually would use the 'cute' smilies too, invariably.I guess u feel the preloaded smilies are too basic and do not cover all the emotions you want to express, right?Thats when u see the ads on the websites saying "New smilies!More funny!100% free!Click here!"

If you install these smilies, u get more than just smilies.You get rootkits too(VERY well hidden malware-like stuff).Yep.Got to think twice these days.The same principle can apply to ads for free screensavers,desktop backgrounds, etc.Rootkits need not cause too much harm,but they really slow down your system if they keep mounting.
So beware.Do NOT click on these ads and install their content.If you already have done so and are worried about it, I'll give u some help.Try this application-RootKit Revealer[RKR].It does not remove the rootkits by itself,but it tells you about the rootkits installed on your system,since it is freely available but the site itself gives you directions about how to destroy the rootkits you find.I think you will be in for a surprise after you see the results your first scan has to offer.
Here's the link-http://www.microsoft.com/technet/sysinternals/utilities/rootkitrevealer.mspx
Don't worry,RKR is supposed to be absolutely safe.
NOTE:If you use some big time antivirus system, u most probably need not worry about all this!Also,rootkits are less in Windows Vista.
Okay then.Best of luck!Stay safe!

16-cores???!!!Overdrive!

Well, It's happened again.

Some company 'Tyan', has made (a?)motherboard that has slots for eight processors.You can put a solo core AMD Opteron processor on each slot,basically.[It only supports AMD's Opteron processors, although.Dumb, isn't it?]

Or you can also put eight dual core Opterons on it. 2x8=? 16!!!

Here's how it works-It has a main motherboard,that has 4 CPU slots.Then,it has another daughterboard that has yet another 4 CPU slots.So in a way, you get a PC with 8 or 16 cores, but not technically.You will NOT get the real performance of an 8-core or 16-core CPU with this layout.It is just namesake-"I have a 16-core computer!".
This stuff could be 512-bit processing capable, though I'm not saying it is.
Let's face it-who needs this much power?It's gonna be USELESS for gaming.Not a single application I know of can utilise all the 16 cores to their maximum potential.Plus, consider the amount of-

• Electricity required,
• Heat generated and
• Space taken,

Alongside so many other factors!!!I'm not so pleased about all this.This really spoils all the fun of waiting for real 16-core CPUs to pop up.
This is crazy,isnt it?Oh well,some people just want attention for things anyone can do,though not as easily.

Okay then.Give me a motherboard with 4 CPU slots.Give me a daughterboard with another 4 slots.Give me a grand-daughterboard that has yet another 4 slots.Give me a great grand-daughterboard with YET another 4 slots.Yay,I have made a motherboard that has 16 slots for CPUs.Yaaaaaaay!!!I have beaten Tyan!!!!!I will earn millions for my new 'discovery'! [Big deal.]

Anyone can make such nutty things,which can handle multiple CPUs.But as long as the CPUs themselves are not good enough & applications are not ready etc,all this fancy stuff is of no use.
Now do you understand how dumb this concept is?(!)
Add to that-the cost of buying eight AMD Opteron dual core processors!!!See?

In human terms,this is how the layout will look like this-
We have to take a two-storey building, ground floor representing the motherboard and first floor representing the daughterboard.The ground floor will have four rooms, each room consisting of one person[solo-core] or one person with two brains[dual-core].(The people act as the processors.) Then, we have person A, the application.Person A will have to visit the building,then a room and finally, reach one of the people.
In real 16-core CPUs,There would be just one person who has all the 16 cores in him,in the form of brains.(so he will have 16 small but powerful brains).By then,the applications too would have commands to give all the 16 brains(cores) individual commands.

Anyway-congratulations Tyan, for doing something like this.

I mean no offence to you readers who find this news exciting.Still, we have to face the truth about all this.in this case, its not so nice.
I guess it would be fun to have one though.....!!!

CPU Development: Too fast,Too furious?

• Solo core.[For ages!!]


• Hyper threading.(fools computer into thinking it has two cores.)[sometime in 2003]


• Dual core.[2005]


• Quad core-[late 2006,almost 2007]


• Octo core-coming 2008!

[PS:I chose Intel's processor line up since they developed faster than,for example-AMD.]

Look at that!Can we go faster than this?We have gone from single to eight cores in just three years!This is defying Moore's Law!

Don't you feel we are going too fast right now?

I bet a lot of you would have bought a Pentium 4 in those days,replaced by one with HT technology.Got hands on it,find it outdated by pentium D.Then find out its defects.Get a Core2 Duo.Then get a Core2 Extreme.Worried about the octo core already?

I dont know about this.Today, we have barely adjusted to dual-core processors.And now quad-core has arrived?Fantastic.

The issue is- even today,VERY few applications are MULTI-THREADED for even dual core processing, remember?You get a new app, chances are, it wont utilise all the cores on your processor, unless it is a high end 3D editing app or such.

In simple terms?Intel and AMD are not giving time for-

1. Us (We the people, not the U.S.!)
   
2. The applications commonly used etc etc...............

-To adjust to new age, multicore processors.Even before applications get used and modified to use dual-core processing, companies create quad core, to give extra confusion.

What is the confusion, you may ask?I'll describe it using myself-

Here's the scene-I made a new software.My software's basic version itself is in high demand.I plan everything well, after spending a lot of money to develop a new, more advanced version of my software.

Then,I find myself between a rock and a hard place.Do I make applications for dual or the quad-core processors?!?Both type of processors are in circulation.Both are popular.I cannot make both,without running skint or bankrupt.Do I ignore the vast amount of dual-cores already in circulation?Or do I focus on future technology, which seems to be spreading well too?As if that wasnt enough, I also hear about octo-core coming up soon..............

Enough to give me several sleepless nights!!!!

It looks like Intel is worried about AMD catching up, though AMD's Athlon 64 X2 did not really touch Intel Core2 duo's performance!

Intel is aiming too high...

There is so much more that could be done to improve dual core processors itself, which has not been done yet.

• It could be shrunk at least a bit more,especially AMD's, which are still manufactured under 90 nm process.AMD is planning to shrink it to 65nm soon, but Intel is already using 65 nm, and will switch to 45 nm quite soon!!The smaller, the better.


• They could poke around and try reducing heat generation, which is always a nuisance.
  
• Plus, they could try making processors that bring back high clock-speed too.


• Then there is energy efficiency.The more, the better, though the Core2 Duo is already good in that area.

Mainly-it's the suspense that is broken!If it didnt arrive already, we would have seen a lot of dual core processors, then slowly moved to quad core after we just cannot get more stuff out of dual core processing.

I dont know about you.You may fantasise and say the faster it gets here the better,but thats not the case.The more time one technology is kept alive,the more refined it gets.The more we can learn from this technology,and use this knowledge to create better technologies in future.
