The 5 W's of Tablet PC - buy or not to buy!

Thinking of buying a Tablet but don't know is it appropriate for you is it that much capable. Should I actually need to but it? Or is it just a waste of money. All of these questions will be clarified in this post. This is not a buying guide rather this post will help you make quick decisions.

Let's answer the very first and the basic question

1. What is a Tablet PC ?
A tablet PC is a handheld device which has comparatively bigger screen than mobile and comes in a variant of 7 inches and 10 inches. foremost it is a touch screen device.

2. What is it capable of?
It is an extremely portable device and doesn’t take too much space. Like today’s Smartphones it can do everything like surfing net, listening to music, watching videos or movies, reading documents, creating documents, etc. You can attach various USB devices like keyboards, gamepads, mouse, pendrives and even HDDs. Some high end Tablets like iPad let users to attach it with HDTV and home theaters.

3. Why should you get one?
In today's fast pace world people want to carry small yet powerful computing devices. Devices like desktops, laptops and Ultrabooks are powerful. But as these devices are huge (as compared to tablets) it becomes difficult to carry them. You need a device that can be an alternative to them.
In addition to it many times you want to do some specific jobs like just only surfing the net or to read a document. That time you will need to turn on that bulky desktop or your laptop which takes a lot of power and time to be used. Where this device remains on sleep mode and with a touch of a button you are ready to go. A tablet is almost a Smartphone but it is just a bit more powerful to full fill your basic needs.

4. What are the benefits of using the tab?
The biggest benefit is that you will save a lot more time and will be fast with your work. You will become much more economical with it as you won’t need a hard copy of your favorite books you can always carry your eBooks.
It is a boon for the desktop users, even if there is no electricity you can view your documents, surf the net or just enjoy with the entertainment stuff. And this was the same reason for me as I'm a desktop user and in addition to it I wrote this post completely on my tab. There are plenty of applications on various app stores which make the tablet a wonderful device. You can synchronize your work with these applications.
While traveling you can use your tablet to be a Media player or stay connected with help of your Data card.

5. Why should you avoid it?
Okay we have covered almost everything but now is the time why you should give up your thought on buying a tab. Despite of its portability and its form factor I should remind you that it is still a bigger version of a Smartphone. If you are thinking that it will perform like your quad or dual core processors then you are making a big mistake it won't perform heavy task like encoding video ripping etc as it has not been meant to be used for that purpose.

Previously in this post i said that it is almost a Smartphone but it is not, as you won't get calling facility as this doesn't serves SIM card facility. However a few Tablet makers have started manufacturing SIM based Tablets. But to tell you one thing you wouldn't like to carry this bulky Smartphone to take it every time just to attend a call or just messaging. Just think yourself carry your so called "SIM enabled" Tablet over your ear.

In the end i would like to suggest you don't go for cheap budget tablets. Although these are not very bad but after some time you will regret it. I myself use a Karbonn Smart tab 3, i bought it for all the above reasons but now i wish i could buy a bit more high end device. Almost all the companies are using the same specs but always watch out for RAM i will suggest check for 1GB of RAM this won't let your device to slow down. And last but not the least check every device physically as its in the saying "All that glitters is not gold" Some times cheap devices might outperform the more priced ones.

Review: Philips SHP2500

Hello all it is the same your own Cray, today I have come with a totally new thing , a review on a product, I know you were expecting  something better than this, but today you have to take this, just kidding have a read this might help you if you are in a mood to buy this product.
 It’s a headphone review the product is the Philips SHP2500 headphones.

Build:  Well the product feels all plastic, from head-toe it’s all plastic, but the look never feels so plastic, in fact from afar it will look Metallic, But this plastic thing has its own advantage its terribly light weight!!!! It is feather light weight. Many headphones will feel you bulky over your head, but this one feels a part of your head.

Comfort:  Well I’m using it right now, no itching, and no pressure on my ears too, I don’t know whether I will ever get such comfortable headphones! The soft cushion ear pads are so soft and it adjusts according to your ears, as it is an over-the-ear headphone your ears will fit perfectly into it! What ever is the size of your ears (won’t mention it for elephant ears ;)    )

Sound Quality:  This purely depends on your environment. Where are you listening to them? Well I tested these in as many different environments as possible.
How I tested them: I used a common song for all the environments. The song was “New Electro Dubstep March 2012 Avicii, Skrillex, Knife Party” (this is a bit amplified version, and yeah I’m a Dubstep lover!)
And here are the results:
At home: It will really feel like home, as this area is not pretty much isolated, you can possibly hear noises in the background, there were no lack in the sound quality, treble and Bass were sounding perfectly where as the mids were lacking somewhere.
Streets: these are not meant for streets buddy!!! Better you don’t buy if you are looking this for streets. These are just a disaster for this purpose.
Bus/Traveling: Again not meant for the purpose!!!! The noise is clearly audible, where as the music is very feeble, u can hardly hear the song.
Metro: A small gain in the sound can be observed, but still just for the purpose of listening can be achieved!
Now what do u expect testing this on a plane, who will pay for that? Just kidding, well as u must have got some clue in ur head the quieter it gets the better is the possibility of good sound quality.

Miscellaneous: well the greatest benefit of this headphone is its cable (sometimes can be a mess too). This headphones comes with a cable of 6 meters (yes “OMG 6 meters!!!!”) so a boon while watching late night movies on TV or on lappy, not a single bit of noise would leak out of the headphone plus u will be sitting in ur couch.( yeah that’s for u stop being so happy!). Plus it comes with a 6.3mm jack too so whenever u feel like plugin it in amplifier. There is a volume controller too but i found it of no use.

Last verdict:
Still you haven’t got it, it is best/perfect for listening in studio or recording environment. The headphones are nice but not well enough for daily purpose, you can use them with your computer /lappy/TV and it wont disappoint you, but better avoid it for outdoor usage. Flipkart sells it for a price of 650 bucks and I don’t think these are value for money. Better go for some cheaper ones which are good on sound and quality. From my side I'm giving a 2.5 star out of 5.

Specifications :

• Diaphragm: Mylar dome
• Acoustic system: Closed
• Magnet type: Ferrite
• Voice coil: Copper
• Frequency response: 15 - 22,000 Hz
•Impedance: 32 Ohm
• Maximum power input: 500 mW
• Sensitivity: 106 dB
• Speaker diameter: 40

• Connector: 3.5 and 6.3 mm stereo
• Detachable cable
• Finishing of connector: Chrome-plated
•Type of cable: OFC

I hope you liked the review for more reviews comment please.
thank you ;)

Free Operating System

Free Operating System. Yeah you heard it right. We all love free stuff especially in India. We are always sneaking around for free stuff. I’m not saying piracy here. But yes free stuff. The best part about free stuff is? its free works almost every time great, today I’m going to tell you more about it.
            Operating systems are software that supports a computer's basic functions, such as scheduling tasks, executing applications, and controlling peripherals. We pay thousands of bucks on it likewise the current Windows 7 Ultimate costs around Rs11000 (approx 200$) or many of you download it by illegal means. Man why to download it, you are supporting piracy. You don’t need to when you get it for free. I’m not going to tell you how to get windows 7 or any other OS which is available in the market for free. Rather I’m going to discuss more about Linux OS. Yeah Linux, you must have stated thinking “this guy is crazy for Linux” but that’s our future dude. Where we are going to use free OS. I don’t know anything about foreign countries but here in India we definitely have a scope of Linux.

Reasons for using Linux

  • Free: First of all the main reason Its Free and Open Source which means its source code is available to you and you can modify it, if you have skills and distribute it over the networks and nobody will give a shit that why or why not you modified the OS because its all legal!
  • Flexibility: Next it supports every kind of PC almost every kind whether its Intel or AMD, high performance or an age old dumb PC it runs pretty well, that’s the biggest strength of Linux. So if you have a Pentium III or Pentium IV doesn’t matter an AMD Athlon processor doesn’t matter! It will run w/o any hiccups!
  • No Virus: Its is not prone to virus and infections, yeah there are practically No viruses for Linux because even if anybody wants to write a virus code, then the open source community will repair it thinking it as a bad code. So you will be safe all the time ;)
  • Working working!: Does all the work of basic computing, earlier there was a time when there was a shortage of Linux users so there were less applications for the need, now as the no. is increasing so is the need.  Just name any software and you will be having that kind of application for you. You have to just name it now (a few exceptional are always there).
  • Control: Greater control over the OS. You can handle each and everything with greater flexibility.
  • No aspirin: No headaches for driver problems(well 99/100 times)
  • Beautiful: Added GUI support offers great graphics and User experience, Linux nowadays is quite attractive. You will have love at first sight thing in your mind.
  • Security: Better encryption and security for your stuff and data.
  • Pre installed apps: All the essential software are pre installed in the system.

There are many more reasons which might compel you to use Linux over Windows.
So it must be buzzing in your head “whether it will be easy for me to switch from windows to Linux? Or will I get proper support for Linux if I get stuck somewhere?”

The answer to these questions are both Yes as well as No. Yes because as in windows you can all the time hover on to the representatives of windows with your problems but in Linux there is no dedicated support yes the developers will help you with everything they have got. But no one to be held responsible later on. There are forums for every OS and Blogs where you can post your problems. 
              Now coming on to switching part, just tell me what was your experience when you first used a Windows PC in your schooling or the first time touched a computer? It must have been all messed up, confused you were mumbling-jumbling on to the things. The same you will feel with Linux (now everything has its first time). Don’t worry but it will actually feel much more difficult than the strangeness because now you are habitual of Windows environment you know where each and everything lies in your PC and your brain will force it to think in that way. So just one thing you have to remember “To be patient and be calm and cool “ with this principle things will work like a charm.
            Now I’m sharing my personal experience with you, I first installed a Linux system on my Pentium IV (yes I once had that crap and I still have it but now not using it). That was Ubuntu 9 I remember that. I just removed it the very next day. Man I had a hard time figuring out what and why it worked seriously WHY!!! “Why did they even make this?”
            But now after giving time to it I have used almost every popular Linux OS that is available on the net and believe me the flexibility it offers is speechless! Currently I have both Win 7 and Linux (Ubuntu 12.04 + Opensuse 12.1) and they work flawlessly. I’m a gamer that is the main reason of using Windows otherwise I can use a Linux OS every time for my purpose. But the latest news I got is the popular PC gaming service ‘Steam’ announced there version on Linux now that’s what I call “killing two birds with one shot” they are encouraging Linux gaming!!! That is pretty impressive for me.

But I need to show you the other side of Linux too.
  • As I said there is no constant support for you.
  • You need a net connection for installing applications.
  • A few applications might not have a substitute or your purchased software like Adobe Photoshop may be useless for you in Linux.
  • Still not that good for gaming.
  • Difficult to find rare hardware drivers like graphic cards(not so frequent revisions of drivers)
  • You won’t be able to compile programs from self. If you download them offline.

At last I would only say just give it some time and after that you will love using it. And now after reading this article you are in a mood to try out Linux, the post below might help you or just click here.

Thank you :)

Installing Linux on virtual box

Hey Hi and hello to all, ended up here on my blog. why what happened??? you are being taught Linux in your college or school?? and you are freaking out how to install it so you can learn it? don't know whether to put it in dual boot or not but having trouble installing it. or you are just in a mood to try Linux because everybody said "its a free operating system and it can run smoothly on your PC"  oh yeah its definitely free as its open source.
ok forget about open source that is a big term for you just remember its free.

So here we go with the routine. It has two parts, part one which is setting up the Virtual box and part two installing the OS onto your HDD.

Things required:
Oracle Virtual Box(free)/VMware workstation(paid+advanced)
A system with virtualization enabled (VT-x on Intel and AMD-V on AMD processor)
any linux OS or live disc you want to install 

Skill: novice
Time: 1/2 hour
Difficulty: easy

My worthy Disclaimer: This is as educational post and you can find many of these articles on net, and mishandling the software may lead to system crashes, so please stick to the guide and if you want to experiment anything you are doing it at your own risk!
Part I

So lets start the game:

1) Download Oracle Virtual Box from the official site. just click it over and it will start the download. currently its Virtual box 4.1.18 available. Now install it that will be quite easy.

2) After that run this application by double clicking on it, the first interface you will  see is like this

                                                                 (click to enlarge image)

you won't see tinycore or xp, oh man you haven't installed them yet :D
3) Now click on 'New' a blue circle in the top left a window will appear, click next. after that it will ask you to name your virtual machine(VM). ok for demo i will be installing Opensuse 12.1 So I'm naming it opensuse it will automatically detect 'Operating System' and "Version'. now click next

4) After clicking next it will ask you for the RAM, how much memory you want to allocate for the RAM . Now this purely depends on your system, how well is your system configured, it may be a very high performance PC or a "just study" PC. plus are you a multitasker or not. suppose if you are on low specs likewise 1GB RAM allocate 256MB of RAM that will just do for you but you might experience sluggish behavior, i said "sluggish" now many of you will say you are wrong linux runs pretty well on low specs PC too. I agree with you but at current you will be working on your windows OS and virtual box will be an application. so in that way your host OS i.e windows OS will also need RAM and guest OS i.e Linux will also need RAM. that is why I'm saying this it may .
              Note: Don't allocate too much RAM to guest OS otherwise the host OS will not work properly and you may experience system crash.
At last I would say the RAM part is purely on your choice here I'm allocating 1GB to it. ok moving on now.

5) Now comes up setting up the Harddisk space for your VM. Actually what VM does is it fools the guest OS by telling it that i have a set of hardware for you. But actually you always had a processor a single HDD. so VM is just fooling around the OS and creating an environment for the Guest OS.
Click next a new window will pop up, asking the type of virtual disk, you can choose from 4 different options you can choose 'VDI' the native disk or 'VMDK' if you want to export it and use it with VMware worksation later on in future. click next and let it remain on Dynamically Allocated.

So setting up the HDD select the place where you want to store the VDI file. Now provide it at least of 10GB of space if you have, otherwise 8GB is also good. I said 10 because it is a difficult task to increase the disk space later on. and don't worry thinking " man my space will get wasted" don't worry it uses dynamic memory allocation which allocates memory when it is needed. just check the space on your C drive after allocation it won't show any disk usage stats. thats Dynamic allocation ;)
finally it will show you the summary lastly click on 'Create'. and your HDD is done.

6) Just after that it will review your VM settings if every thing is right click on 'Create' and here you are, you have setup your very own opensuse Virtual machine.

7) Now click on opensuse and click on settings>system now in motherboard tab uncheck floppy from 'Boot Order'

8) Now go to 'Storage' there in IDE controller click on single disk with a plus sign saying "Add CD/DVD device" a small window will pop up asking to choose the disc or to leave empty click on 'Choose disk' now locate the ISO of the Opensuse 12.1 in your directory wherever you saved it. and open it.
oh i didn't told you where to get the live discs or the ISO files. In my earlier post i.e Linux Vs Windows i have given the sites for a few Linux. those are bit old but they are the official sites.
For latest Opensuse 12.1 click here. and choose whatever download is suitable for you.

9) At last click OK and now you are set to launch your Opensuse OS.
10) Now click on opensuse and click on start. the booting processes must have started.
Part II
 1) The first screen it will show is like this, with the help of keyboard navigate to "Installation' and click enter

2) There will be a Welcome screen after pressing enter now again click next to proceed

3) After clicking next it will ask you for clock and time zone select Asia( for India) in Region and Kolkata. then click next

4) Now the trickier part setting up the disk( you are with me don't worry ;)), click on create partition setup choose 'IDE disk.......' in the next screen proceed to next and then again next.

5) Setting up the user enter your credentials and password and please remember that password that might come in handy any time. click next to proceed.

6) Check all your setting in the Live Installation setting page and proceed to next, now let the installation begin and let it complete later on while it has finished copying the files it will ask you to reboot click on 'Reboot now'. after rebooting it will show you the same start up screen navigate to 'Boot from Hard Disk' it will return to installation process and now you must have reached to Automatic configuration in which it had started downloading the packages from the net i have skipped that part for now. But you please continue with that. those are essential for your OS running.


7) After the download completion it will enter to the user i.e the actual OS GUI. once reached shutdown the OS and go to settings of the opensuse and in storage right click on the  IDE devices and click 'remove attachment'. now it will let you boot normally.
Opensuse 12.1 GUI
 oh pal its been 5 hrs i have been writing this guide, now still if you have any query below is the comment section for you, you need help getting software or running any command I'm there for you.
But for some native windows application you still need to use your windows OS, otherwise there is a software in Linux called 'Wine' that can run Windows application on Linux. And this is why i was persuading you to install Linux or any other OS on a Virtual machine. because it always comes in handy to switch over in seconds ;)
thanks for reading :)

Clean Micromax Q5 trackball. [solved]

Are you a Micromax user? a Micromax Q5 user?? having trouble with the trackball?? want to get it serviced but the service center takes many days to get it settled? or they charge 250 bucks?? Is it so??
             Don't worry guys here is the solution for you now. now you can clean your trackball just in half an hour with just simple tools! and too free!

Things Required:
A small head screw driver(can be found at any electrical shop)
a thin knife
a safety pin
ethanol/petrol (whatever u get easily)
An old tooth brush or any brush.

Skill: Novice
Time: Approx 1hr
Difficulty: Medium

Disclaimer: Before we start i would like you to know that this procedure will void your warranty. and while following this guide if anything bad goes with the device, i would not be held responsible for that. And this guide is strictly for Micromax Q5 don't try it on Q7 as they are very much different. But don't worry anything won't go wrong unless you screw something.
So lets begin ->

1) Remove the Steel back plate and remove the battery, now take the screw driver and unscrew the four screws which you can see at edges of the body
Ah that was simple!

2) Now with the help of the safety pin remove the two rubber stoppers at the top body which are above the camera. underneath you will see two screws, unscrew them too.

yeah i know there are too many hair!!! but i ain't going for waxing! ;)

Now the difficult part.
3) use the knife or the screw driver to dismantle the upper and lower part of the body. Do it carefully and slowly otherwise you might break the locks which held them together. well I'm doing this from the upper part of the LCD but if you are not sure try to do it from the bottom(the USB and 3.5 jack part) as there will be less chances for the damage but be careful with the mic.

4) Oh man you dismantled the phone that is nice, your first step for the mobile geek! ;) ok now as you can see above the keypad there is the devil(trackball) which is not working properly. Push it from the front side don't worry it is the glue only which is holding it. it will come easily in your hands.

 5) Again take your safety pin, and carefully remove the locks of the trackball it will be a metal lock like this.

took this pic all alone!!! that was hard enough phew!

6) After this it is very easy remove the magnetic rollers you must be thinking what are these rollers for, they send the magnetic signals to the receptors which calculate its rolling speed and act according to it.

7) Now take your brush soak it in acetone/ethanol or petrol and brush it on the rollers so that every bit of dirt will be removed from them and if you have plenty of time use a fine safety pin to clean it.

8) Same you have to do with the plastic ball and it must be all clean!

9) Now clean the sensors which is on the board do it very very gently otherwise you might end up with a faulty sensor remind you again it is a very delicate thing. Don't ever scratch it with a safety pin or any pointed material as you might remove the coating as i did and now its NOT WORKING PROPERLY. Do it with gentle hands with the brush and acetone, that will be enough.

10) Now you are all done assemble every thing as it is and its all the reverse steps of the above guide.
just follow it reversely and if there are any problems, comment please i will help you with whatever i can.
 any doubts comment section is all yours

              If you are facing problem setting up the trackball again see this.


Thank you :)
