Basic tips for increasing your computer speed

After purchasing a new computer you might have really noticed and probably didn’t like one thing: The gradual decrease on the speed of your computer (I am not talking about internet speed).This happens due to many reasons. I am going to give you a basic idea of prevention and recovery.
1) Your computer might have been infected by a malicious file; it might be due to surfing on the net or putting an infected USB into your USB port. It takes only 15 minutes to get infected on the net if you are not using an anti virus .you can buy or download an antivirus to get rid of your problem
And I recommend you kaspersky internet security (well iam using it) .you can get it about Afg 1500
Or download free trial version from www.cnet.com

2) The disk partition that you have installed your operating system (windows or Linux and mostly drive is C by default) might be running out of space, and that causes slow speed on your pc. Delete the unwanted files and folders from particular drive (that includes my documents too ...)
If you want to uninstall some applications which have no use any more, then un install them from control panel ->add and remove programs.

3) Your Drives are like a book shelves and files, programs you installed are like books, if the files are not organized well and not well installed with particular address, A randomness comes to existence and that takes a lot of space, it is like throwing the books without arranging them in an order in the shelf .so often you need to do a defragmentation. That is the procedure of arranging the files into order which brings out more space to use. To defragment your drive
Go to start menu->All programs->Accessories->system tools ->disk defragmenter.

4) Due to some reasons some of your kernel codes are missing from you operating system, or your operating system (means your windows or etc) is facing a problem, in this case you need to back up your data, and format your system and re install your operating system.

5) If the above tips still do not help you ,well my friend it is time for you to scratch your pocket and get a new RAM.I recommend you to get DDRRAM (Doubly data rated RAM).Some computers provide the option of upgrading your RAM.

Electricity without wires ?

Humans have always lived a curious life,from making fire for their cooking and protection to using the up to date technology , from using salt in their food to using nano technology for pain relief,and now we(not Afghanistan anyway)are in a era of pawing the edges of connecting our home devices and plaguing them to electricity using no wire,what??No wires??..YES and it is POSSIBLE.Today I am going to tell you how it works. It is Neither that difficult nor that complicated case , using 2 magnets and coils around them they generate electromagnetic field and place these 2 magnets at a distance (in meters only for now) now between these 2 magnets there will be electromagnetic induction (simple words ) electromagnetic wave propagation which is not considered(not yet) to be harmful for humans . at one side they install a transmitter and converter to convert power(electricity) to electromagnet waves and other side electromagnetic wave receiver and another converter to convert the recieved electromagnet waves to power(electricity), Due to electromagnetic induction in between these 2 magnets waves will be sent and received ,there you go it is that easy ,but most important thing is that they come up with an idea like this.after all Hafiz my 11 grade classmate was right about electricity without wires ,when all of us were laughing at him

which Internet browser should i use?

long time ago when there were witch mountains and pony tail horses ,this started.so called Battle of browsers , the competition between browsers , well in that time internet explorer of Microsoft and navigator of Netscape(which is not famous among non computer engineer people) were the biggest shots of the time .but today there are many other browsers on the market screen and each have their own merits and demerits i will rank them based on my opinion and experience.

Fire fox

It is developed by a developer group called Mozilla, Firefox is fast and easy to use and has good security mechanism. It comes with Linux series(Ubuntu, Red hat....) pre-installed or you can download it from Mozilla`s website, and one good thing about Firefox is that user has been given the option to customize the browser based on his or her interests.I gave it 4 out of 5.

Safari
It is from apple ,comes with Macs and has good look .Fast performance is another good thing about it,it is a bit strange to use with windows.I gave it 3 out of 5.

Google chrome

new in the business , developed by Google .looks stylish , does not have good security compare to Firefox ,but very compatible .user can customize it and it has very user friendly interface, that is why i use it(lol).I gave it 3 out of 5.



Internet Explorer
It is the oldest among all these ,developed by Microsoft comes with all windows series(except with windows 7 for EU).I hate to say it , it is slow and got low performance based on what i have experienced ,and it looks boring , because they didn't change the look of it from 90s. i gave it 2 out of 5.

Note:for your own good please always remember to turn your cookies off.cookies are the mechanism in your browser to keep the track of your accounts , websites you visited and etc, so that if your girl friend or your father sees your browser history ,they shouldn't get shocked :)

How to download a file from youtube easily?

There are a lot of softwares available for this purpose , for Some you have to pay or you will just get the trail versions . but anyways it would be difficult for some one to use or download an additional file for the very file he wants.
well today i am going to tell you how to download a file on the net using nothing but your browser and your net connection and you don`t need to have extra softwares.

step1) Go to youtube and select your favorite clip.

step2) On the address bar you should see a URL address -Example :www.youtube.com/examplexyz.... URL stands for universal resource locater, a unique address for files on the net .

step3) copy the URL and go to www.savevid.com , here you will see a bar and a download option, past the URL that you copied from youtube , click download.

step4) To confirm , the website will show the name of the file you selected , and will ask what quality and formate you want , and then the download will start , if you are using Google chrome as browser like I do or opera , the download will be shown on the bottom of your browser ,but if you are using fire fox or IE then there will be another window for the download .

Top sites!

It does not take you to be a geek or a computer nerd to surf and like a website,you may like a website because you download a video file ,an audio file for your ipod ,or you may like it because you get the news.For some of us who mostly download movies and documentaries using torrent, i would like to suggest 2 websites for them.
www.mininova.org and www.thepiratebay.org

these are 2 websites that i personally download movies from ,one tip for my friend out there , please check the number of seeds for any file before you download them , both sites show the number of seeds,the more the better , file size and the date .
Though one thing which bothers me about these 2 sites is the SEARCH , it is not that accurate , sometimes they may suggest something totally irrelevant.you have to type the exact key word.

Those of us who are interested in improving their general knowledge i recommend you the following sites

www.ehow.com
www.howstuffworks.com
www.about.com

From dating a woman to connecting your laptop to a desktop monitor or knowing the geographically correct location of Afghanistan in degrees, these above sites give you information ,howstufforks will provide the relevant videos too.

For downloading small to big size softwares , ebooks... i suggest you www.cnet.com
you can make an account free of charge or you can simply download for free , but sometime the softwares provided will be trail version , you may need to buy the serial code(who does that ?),if you dont want to download trail version , just check the extension of the file , it may end with .trail or _trail .

for Electronic reviews and previews check out
www.sciencenews.org
www.wired.com
www.technologyreview.com

these sites will compare the products , tell you the current market price , and advice you on the subject.

well friends these are the sites i recommend, if you want any sort of clarification please feel free to put comments in my facebook or here in my blog , i promise to read it and reply back , till then take care and have fun :)

Are you using facebook,or is facebook using you?

In some ways it’s a great development, making it simpler to connect what you read, watch and listen to. But there’s a nagging suspicion that when Facebook says it’s simply reacting to changing norms about how public we want our lives to be, that it’s actually forging that condition, not reacting to it.

And when I say forging, I intend both meanings of the word.

The question is whether you are actually using Facebook to keep in touch with your friends and family — or whether Facebook is just using you.
With a few deft maneuvers, Facebook is aiming to make itself the center of the internet, the central repository and publisher of what users like and do online. Facebook’s new tendrils will likely give what is already the world’s largest social network enough data to compete with Google for billions from advertisers who are hungry to spend their ad dollars on ads they can target specifically.

Facebook’s main lever to get all this data funneled to them is a simple “I Like” button, which websites can embed on their pages with very little effort. When a user clicks on that button, they signal to Facebook to add their vote on their user stream that they are a fan of this NFL player, this romantic comedy or that blog. Websites that embed some smart metadata (geared mostly for Facebook) into their pages let Facebook know what kind of thing a user likes, so Facebook can automatically add it to the relevant section of that person’s profile — with a link back to the original site.

Sites can also choose to install a sharing toolbar that sits at the bottom of your browser while you are on your site, or an even larger widget that shows what you and your friends are currently doing on Facebook — and with the “Like” button — around the net.

The setup makes it simple for users logged into Facebook to update their profiles and broadcast their activities to the world (liking something, including a political or religious group, like many parts of all Facebook profiles these days, is public information, no matter how you configure privacy settings.)

Logged-in Facebook users will also be transmitting information about their travels around the net to Facebook servers whenever they visit a page deploying the Like button, regardless of whether they actually click that button or not. Facebook also plans to transmit user data to some web services ahead of their visit — so that when you visit the site, it’s “instantly personalized.” In practice, this means that if you are new to the music site Pandora, they’ll have a custom station waiting for you based on the music you’ve liked in your profile.

While such tracking happens with third-party ad networks, they don’t know your name or anything about you other than where you go on the net. Facebook has far more to connect your browsing information to. Perhaps the closest analog is Google’s creepy Web History which tracks you around the web and records every URL you visit, but that system only works for people who install the Google Toolbar and who don’t unclick the “Web History” button when they create a Google account. That system, along with your search history, are also separate from Google’s ad tracking system, which doesn’t know your name or who your friends are.

Certainly, this sets Facebook in some competition with Google, especially with AdSense, which is Google’s ad platform that publishers use to put ads on their sites.

But reports that Facebook has “won” the web are laughable, especially given the numbers Google put up this month, with more than $6 billion in revenue over the first 3 months of the year. Moreover, the bulk of Google’s ad revenue comes from “contextual” ads, which rely on the contents of a web page or search query. It’s far from clear that targeted ads — even ones based on deep profiles — would do better than the ads on Google’s search page, even if Facebook eventually thinks it can build a search engine whose rankings are set via the data it collects from users.

Facebook built much of this easy-to-use system on “open” standards, as WebMonkey’s Michael Calore reports, even as it sucks the data into a closed community. But those standards are used almost exclusively by Facebook, and ignore the work that’s been done by others to create universally understandable meta-data.

Moreover, the Like button feeds exclusively to Facebook. If your primary identity on the net is at LinkedIn or Google or MySpace or god forbid, on your own domain, this button does you no good. Facebook didn’t build this architecture to make the net better, it built it to make Facebook money.

You can opt out of some of this through Facebook’s increasingly arcane privacy settings, though most won’t do anything to stop Facebook’s relentless push to make people’s profiles public.

And at least until someone comes up with a universal “like” button that feeds your votes to the place you want it to go, the web will increasingly become an extension of Facebook. The question for many in the days to come is whether you are actually using Facebook to keep in touch with your friends and family, or whether Facebook is just using you.

Apple MacBook

Updates to Apple's MacBook line of laptops are always closely watched, and they generally fall into two categories: there are major evolutions, such as the switch to aluminum unibody construction in 2008, and then there are minor spec upgrades, typically small bumps to processor speed and hard-drive size.

The newest version of the MacBook Pro line surprisingly falls outside of those two extremes. The iconic unibody aluminum construction remains, as does its large glass multitouch trackpad (in fact, from the outside, the new MacBook Pro looks identical to its predecessor). But the revamped internal components are much more than a simple spec upgrade.

The 15- and 17-inch Pro models have moved to Intel's newer line of Core-i CPUs, from the older Core 2 Duo models (the 13-inch Pro, unfortunately, still uses a Core 2 Duo CPU). Both mainstream Core i5 and high-end Core i7 versions are available. This requires a new chipset architecture (courtesy of Intel) and a switch from the integrated Nvidia GeForce 9400 to Intel's built-in integrated graphics for the systems' default GPU.

Our review sample is the highest-end 15-inch base configuration, with a 2.66GHz Core i7 CPU, 4GB of RAM, a 500GB hard drive, and Nvidia GeForce GT330M discrete graphics. At $2,199, it's definitely expensive, but it's still $100 cheaper than the previous high-end 15-inch MacBook Pro configuration. The lowest-priced 15-inch model costs $1,799, which is $100 more than the previous low-end 15-inch MacBook Pro--but that system now includes discrete graphics instead of only integrated graphics. Overall, this round of updates follows the usual Apple trajectory: keeping the price steady but adding faster, more powerful components.

We continue to pine for oft-requested extras such as HDMI, Blu-ray, and 3G, but at the same time, the Core i7 CPU is extremely impressive, both on paper and in action. With the 13-inch model still stuck with a Core 2 Duo CPU, this revamped 15-inch MacBook Pro now feels like the line's powerhouse flagship model.

As with the previous MacBook Pro models, the unibody chassis starts with a solid block of aluminum, which is carved down, rather than a thin outer shell that has had support struts added to it. The result is a thin yet strong chassis that feels very solid and substantial. Even the $999 white polycarbonate MacBook now uses a similar body type.

We remain fond of the large trackpad that uses multitouch gestures for much of its functionality. In fact, touch controls are almost as vital to the MacBook as they are to the iPhone or iPad (plugging in a mouse is also an option, but you miss out on a lot of time-saving gesture controls that way).

Of the multitouch gestures, our favorite is sweeping moves with four fingers; left or right brings up the application switcher, and up hides all your active windows. Once you get used to that, going back to a regular touch pad is difficult. We've noted in the past year or so that many PC makers have added some form of multitouch functionality to their touch pads, but we have yet to find any that work as well as Apple's.

This year's version also includes a small behavioral tweak, which Apple calls "inertial scrolling." Like on the iPhone and iPad, flicking two fingers up or down to scroll now feels like there's more mass behind the effort, and the page will continue to move slightly after you've lifted up your fingers. The recent Magic Mouse peripheral from Apple included a similar effect.

The 15.4-inch wide-screen display offers a 1,440x900-pixel native resolution, which is what we're used to from previous 15-inch MacBook Pro models. But with the growth of online HD video, and ever-higher resolutions for digital still and video cameras, some users will want more pixels to play with. A 1,680x1,050-pixel display option is now available, which costs an extra $100 (or $150 for a version that also includes an antiglare coating). Still, for a $2,000 laptop, the higher-resolution screen should be included by default.


Apple embraced the simple joys of the SD card slot in last year's MacBook Pro update, but this time around there are no comparable new features (although we're excited that the DisplayPort output now supports audio as well as video).

You do, however, have several ways to push the 15-inch MacBook Pro well past its $1,799-$2,199 default configurations. Bumping the 500GB hard drive from 5,400rpm to a faster 7,200rpm model is a $50 upgrade, and SSD drives are available from 128GB ($200) to 512GB (a whopping $1,300). RAM can be doubled to 8GB for $400, but each of the three base 15-inch models is locked into particular CPU/GPU combos.

The 15- and 17-inch MacBook Pros have "automatic graphics switching," an Apple-engineered variation on Nvidia's Optimus graphics-switching technology. The concept is simple: the system uses its integrated Intel graphics by default, and when an app launches that requires the discrete Nvidia GeForce 330M GPU, it seamlessly switches over to that, then turns it off when it is no longer required.

Previously, switching between the (integrated) GeForce 9400 and the (discrete) GeForce 9600 found in last year's MacBook Pros required you to manually flip a software switch on the power options menu, and then log out and log back in.

The GeForce 330M (available in 256MB and 512MB versions) is not a hard-core gaming powerhouse, but it should be capable of playing just about any current PC game--although you may have to dial down the detail levels or resolution for optimal frame rates. It's the seamless switching between GPUs that interests us more, as it lets you take advantage of the discrete graphics for HD video and gaming, but won't run down the battery when not in use. In the Mac version of Call of Duty 4 we got 34.5 frames per second at 1,440x900-pixel resolution, with 4XAA and other high-end graphics options turned on, and 59 frames per second at the same resolution, but medium in-game graphics settings.
