How to Fool Your Friends by Changing Your Processor's Name!

Hello Friends...

I’ve got a super funny trick to share today! Ever wanted to trick your friends into thinking you've got a super high-end processor like a Core-i10 or something even more insane? Well, you can easily do this by tweaking your processor’s name via the Registry Editor. It’s a harmless prank that’ll definitely get a few laughs. 😄

Steps to Change Your Processor’s Name:

1. Open the Registry Editor:

   • First, you’ll need to access the Registry Editor. Just press Windows + R to open the Run dialog, type "regedit", and hit Enter.

2. Navigate to the Processor Name String:

   • In the Registry Editor, navigate to the following path:
     • HKEY_LOCAL_MACHINE > HARDWARE > Description > System > CentralProcessor > 0.

3. Modify the Processor Name:

   • Once you’re in the "0" key, you’ll see an entry named "ProcessorNameString" on the right side.
   • Right-click on "ProcessorNameString" and select "Modify".
   • Change the value to whatever processor name you want! Be creative—how about "Core-i10 Ultra Super Edition"? 😜

4. Exit and Refresh:

   • After making the change, simply exit the Registry Editor and refresh your desktop. Your new processor name will show up in your system properties!

Important Note:

The next time you reboot your system or power it on, it will automatically detect the actual CPU configuration and reset the processor name to its default. So, this trick is perfect for a quick laugh but won't cause any permanent changes. Let your friend be fooled for a moment, and then watch their reaction when they realize the truth!

Unlock the Magic: How to See 3D Photos with Your Naked Eyes!

Hello Fellow Readers,

This article lets you how to see 3D without need of any special 3D spectes.
The point is to teach you how to see 3D photos on the web. There are many different ways to see 3D, with just as many gadgets to help. The technique I will be showing you requires no special equipment. All you need to do is train your eyes to look at these images in what you might call an “unnatural” way.

 What is crossed eyes?
When overlapping stereo pairs without special glasses, you can get the 3D effect by crossing your eyes or diverging your eyes. I prefer the crossed eye method. I find it easier to control, and it is possible to view larger 3D images than with the diverging technique.

How to do it

• Sit square in front of your monitor, with the image directly in front of you, at about arm’s length
• Sitting further back makes it easier – you don’t need to cross your eyes as much – but makes the image look smaller
• Make sure you keep your head level horizontally, tilting your head will prevent you from merging the images
• While keeping the stereo pair of images in the centre of your vision, slowly cross your eyes
• The stereo pair will go out of focus and you will seem to see four images, as shown in the animation above
• If you find it hard to cross your eyes, it can help to hold a pen in front of you and look at the tip with the stereo pair in the background
• Gradually cross your eyes more and more – if using a pen to assist, start it close to the monitor and move it towards your nose
• Continue crossing your eyes more, untill the centre two of the four images overlap and you see three blurry images, as in the animation above
• Try and hold the centre image together – it is possible to “lock” it in place and see it as one image
• The “locked” centre image should appear in 3D!
• Now the tricky part, focus – while holding the 3D image in place, relax your eyes – drop the pen from your field of view if you are using it
• If you can keep the 3D image locked and relax your eyes, it should eventually pop into focus, as in the last frame of the animation above

What you are doing here is causing your eyes to look at a space between you and the monitor, but focusing the lenses on the monitor. Our eyes never naturally need to do this, so it can be tricky to do at first.

Try it!

Try and see the 3D effect yourself with the stereo pair below.

 

How did you go? If you were able to see the effect, congratulations! It really is very striking isn’t it? If you couldn’t manage to do it after trying for a while, leave it aside and try again tomorrow. It can be tricky to get the first time, but the majority of people can do it. If you find you are unable to see the 3D effect no matter how many times you try, then it may be that you are one of the few who for whatever reason will never be able to do it.

How to Watch a Movie in MS Paint (Yes, Really!)

Ever wondered if you could watch a movie in MS Paint? It might sound strange, but it's actually possible! Follow these simple steps to play a movie directly in MS Paint. This fun little trick is sure to impress your friends, and it’s a neat way to combine your favorite media player with one of the simplest graphic tools available.

Below are the steps to start a movie in MS-Paint

1. Open the Movie: Start by playing your favorite movie in any media player. For this example, I used VLC Media Player, but you can try it with others too.

2. Launch MS Paint: While the movie is playing, open MS Paint. You can find Paint in your Start menu or simply type "Paint" in the search bar

3. Capture the Screen: When the movie is playing, press the "PRINT SCREEN" key on your keyboard. This will capture whatever is currently displayed on your screen

4. Paste in Paint: Switch to the Paint window and press CTRL+V to paste the screen capture into Paint. You'll see the current frame of the movie pasted as an image

5. Keep the Movie Player Open: Here's the crucial part—leave the movie player open and do not minimize it. As long as the player is still active in the background, Paint will display the movie frame by frame

6. Watch the Movie in Paint: Now, just sit back and watch the movie play within MS Paint! It’s a quirky way to experience your media content, and it shows just how versatile these simple tools can be.

You can also save running movie in paint. Now if you open up your paint file, you can see movie is still running if your movie player is not closed.

How to Block a Website Without Any Third-Party Software

There are various reasons you might want to block a website: maybe it's distracting, unsuitable for certain audiences, or simply something you'd rather not access. While some antivirus programs offer built-in website-blocking features, there’s an easy method to do this directly using your Windows operating system, without any third-party software.

In this guide, I’ll show you a quick and simple way to block websites by editing your system’s hosts file.

Step-by-Step Guide:

1. Open My Computer.
2. Browse to your Windows installation drive (typically the C: drive).
3. Go to the following path: C:\Windows\System32\drivers\etc
4. Look for a file named hosts.
5. Right-click on the hosts file and open it with Notepad with admin privileges.
6. Scroll down and locate the line: 127.0.0.1 localhost

Now, to block a website, simply add the following lines below it:

127.0.0.1    localhost
127.0.0.1    xyz.com
127.0.0.1    abc.com

Replace xyz.com and abc.com with the actual website URLs you want to block.

7. Save the file.

And that’s it! The websites you listed are now blocked. If you try to open them in any browser, they won’t load.

To unblock a website:
If you ever want to regain access to a blocked site, just reopen the hosts file and delete the line containing that website’s URL. Then, save the file again.

Why This Works:
The hosts file is used to map hostnames to IP addresses. By directing the specified websites to 127.0.0.1 (your localhost), you’re telling your system that those websites should be redirected to your own computer instead of their actual servers, effectively blocking them.

Final Thoughts:
This is a simple, efficient way to block websites without needing any additional software. It’s particularly useful if you want to control access to certain sites on a shared computer.

If you have any questions or need further assistance, feel free to comment below. Don’t forget to share this post if you found it helpful! 😊

Any query then please comment and share... :-)

Unlocking Android: Essential Terminologies You Need to Know!

Hey Everyone,

Today, I’m diving into the world of Android with a list of must-know terminologies that every Android enthusiast should be familiar with. Whether you’re a tech novice or a seasoned pro, understanding these terms can help you make the most of your device. Plus, I’ve thrown in some fun tricks to keep things interesting!

Android: A Linux-based operating system for mobile devices such as HTC EVO.Versions are alphabetically codenamed after snacks: Donut, Eclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, Jelly Bean.

Apps2SD: A method of storing applications and cache on the device's microSD card.

ADB: Android Debug Bridge (adb) is a versatile command line tool that lets you communicate with an emulator instance or connected Android-powered device. It is a client-server program that includes three components:

APK: Android application package file. Each Android application is compiled and packaged in a single file that includes all of the application's code (.dex files), resources, assets, and manifest file. The application package file can have any name but must use the .apk extension. For example: myExampleAppname.apk. For convenience, an application package file is often referred to as an ".apk".  

Baseband: is an adjective that describes signals and systems whose range of frequencies is measured from close to 0 hertz to a cut-off frequency, a maximum bandwidth or highest signal frequency; it is sometimes used as a noun for a band of frequencies starting close to zero. Baseband can often be considered a synonym to lowpass or non-modulated, and antonym to passband, bandpass, carrier-modulated or radio frequency (RF).

Boot Animation: Boot animation is a term for a graphical representation of the boot process of the operating system.

Bootloader: This small program's only job is to load other data and programs which are then executed from RAM.Often, multiple-stage boot loaders are used, during which several programs of increasing complexity load one after the other in a process of chain loading.

Bootloop: When your system recycles over and over without entering the main OS.

Beta: is the software development phase following alpha. It generally begins when the software is feature complete. Software in the beta phase will generally have many more bugs in it than completed software, as well as speed/performance issues. The focus of beta testing is reducing impacts to users, often incorporating usability testing. The process of delivering a beta version to the users is called beta release and this is typically the first time that the software is available outside of the organization that developed it.
 The users of a beta version are called beta testers. They are usually customers or prospective customers of the organization that develops the software, willing to test the software without charge, often receiving the final software free of charge or for a reduced price.

Compile: It translates (a android program)from a high-level language into another language, usually machine language.

CPU: It stands for Central Processing Unit and handles all the complex mathematical formulas necessary to do everyday things like surfing the Internet.

Custom: Independent developers who like to customize their devices beyond the standard options provided often tend to release the fruits of their labor for the rest to enjoy, in form of custom ROMs.  

Cache: A component that transparently stores data so that future requests for that data can be served faster. The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere. If requested data is contained in the cache (cache hit), this request can be served by simply reading the cache, which is comparatively faster. Otherwise (cache miss), the data has to be recomputed or fetched from its original storage location, which is comparatively slower. Hence, the greater the number of requests that can be served from the cache, the faster the overall system performance becomes.

CDMA: Mobile phone standards called cdmaOne, CDMA2000 (the 3G evolution of cdmaOne) and WCDMA (the 3G standard used by GSM carriers), which are often referred to as simply CDMA, and use CDMA as an underlying channel access method.

ClockwordMod: Also called as CWM is a popular custom recovery for Android phones and tablets developed by Koushik Dutta (Koush), a well*known name in the Android dev community. ClockworkMod recovery allows you to perform several advanced recovery, restoration, installation and maintenance operations on your Android device. It allows user to install custom ROMs, kernels, themes, mods and more however, installing custom kernel from CWM is not yet available to Xperia family.

Dual Core: A dual core processor is a central processing unit (CPU) that has two separate cores on the same die, each with its own cache time. It essentially is two microprocessors in one. This type of CPU is widely available from many manufacturers. Other types of multi-core processors also have been developed, including quad-core processors with four cores each, hexa-core processors with six, octa-core processors with eight and many-core processors with an even larger number of cores.  

Dalvik Cache: Writable cache that contains the optimized bytecode of all apk files (apps) on your Android device. Having the information in it's own cache makes applications load faster and perform better.

Flashing:The ROM memory used in smartphones and tablets etc. is often same as flash memory found in SD cards and USB flash drives, simply optimized for better speed and performance while running the operating system.

Flash Memory: Flash memory, also known as NAND memory, is nonvolatile – keeping information even when the device is off. Flash memory in the device is equivalent to the hard drive in a computer. This is where the device’s operating system (sometimes called firmware) and applications are stored. Flash memory is slower than RAM, but is (almost always) faster than SD cards. 

Hotspot: A spot that offers Internet access over a wireless local area network through the use of a router connected to a link to an Internet service provider. Hotspots typically use Wi-Fi technology.You can connect wifi campatible devices to it.

Kernel:A kernel is a layer of code that allows the OS and applications to interface with your phone's hardware. The degree in which you can access your phone's hardware features depends on the quality of code in the kernel. The homebrew (rooting) community for HTC has made several kernel code improvements that give us additional features from our hardware that the stock kernel does not. When you flash a custom ROM, you automatically get a kernel. But you can also flash a standalone kernel ROM on top of the existing one, effectively overwriting it. These days, the difference in custom kernels is less about new features and more about alternate configurations. Choosing a custom kernel is basically choosing one that works best with your ROM.  

Nandroid: To backup the current running rom. 

Overclock: To increase the speed of your CPU.

Recovery Mode: A small separate operating mode you can boot your device into, used for device administration. Two popular custom recovery modes are Amon Ra and Clockwork.

Ram: (Random Access Memory) A group of memory chips, typically of the dynamic RAM (DRAM) type, which function as the computer's primary workspace. When personal computers first came on the market in the late 1970s, 64KB (64 kilobytes) of RAM was the upper limit. Today, 64MB (64 megabytes) of SDRAM is entry level for a desktop computer, a thousand times as much (see SDRAM).

Root: The first level of a folder.

Sideloading: It means installing applications without using the official Android Market.

SDK: (SDK or "devkit") is typically a set of software development tools that allows for the creation of applications for a certain software package, software framework, hardware platform, computer system, video game console, operating system, or similar platform.

Underclock: To reduce the speed of your CPU.  

Undervolt: Undervolting means taking some of the voltage from the CPU which in return gives a longer battery life and lower temperature during intensive use of the CPU.

USB: Stands for Universal Serial Bus. Is a method of connecting devices to a computer. Most smartphones now use microUSB cables to charge and sync.

WiiMax: (Worldwide Interoperability for Microwave Access) is a communication technology for wirelessly delivering high-speed Internet service to large geographical areas.
