Cracking windows 8 apps

I was looking for a crack of ‘Gravity guy’ to unlock Multiplayer mode. Boom! I found this! Something that can crack any application on the Windows 8 store. It does have its draw backs though.

 
Cons:
- The app you want to crack should have a trail version (Try) available on the windows 8 store
 
 Its worth giving it a shot, considering the fact that most of the major apps like ‘Angry birds’, ‘Fruit Ninja’, ‘Cut the rope’ and not to forget ‘Gravity guy’ has a try optionDownload:

Just extract the files after download and browse to wsservice_crk_src_1.4.2wsservice_crkrelease
and read for_noobs.txt

WiFi hotspot in windows without any 3rd party software

Start a hotspot on your PC without any 3rd party software installation just with 2 commands!

 

This approach will start the hotspot instantaneously unlike connectify
Not a fan of commands? – worry not. I made the commands into a setup file for you. Of course this kills the purpose of this post but what the heck. The intention is to make it quick, minimal and simple after all.

 

  1. Super simple:
    • Download setup.exe and start.exe
    • Enable Internet sharing to hotspot
      • Network and sharing center
      • Right click on your LAN network –> Properties –> Sharing
      • Check “allow other network users to use this comp. internet”
      • Select your hotspot as the sharing enabled network

  2. Command way:
    • Open command prompt with admin rights. (press start button and search for ‘cmd’, right click and ‘run as administartor’)
    • To create hotspot, use: netsh wlan set hostednetwork mode=allow ssid=<hotspotName> key=<hotspotPassword> keyUsage=persistent’
    • Then to start hotspot, use: netsh wlan start hostednetwork’
    • Enable Internet sharing to hotspot
      • Network and sharing center
      • Right click on your LAN network –> Properties –> Sharing
      • Check “allow other network users to use this comp. internet”
      • Select your hotspot as the sharing enabled network

That’s it! No need of any 3rd party software which may slow down your PC. If this method fails I recommend you to try ‘WiFi hotspot creator’, light and simple before going back to ‘Connectify’. Hope that helps

Speed testing Windows 8 and OS X Mountain Lion

An article from thinkdigit said,Windows 8 has reached its “release to manufacturing” (RTM) state, and Apple’s Mac OS X Mountain Lion has been out for a few months, so now’s the time to pit the two new operating systems’ performance against each other. Even though each OS is in its final state, there are still a few caveats: the tests were run on an Apple laptop, since it’s not feasible to install Mountain Lion on anything but Apple hardware. This means that Apple gets the advantage of tuning the OS precisely to the hardware configuration. Windows, by comparison, must run on a huge array of different hardware combinations from many vendors.

I tested by installing 64-bit Windows 8 RTM on a 13-inch MacBook Pro (a 2012 2.9GHz Core i7 with 8GB RAM) using Boot Camp. The setup process was pretty smooth, though I’d imagine that not all the Windows hardware drivers were perfectly tuned for the MacBook. Nevertheless, the system was snappy and responsive running Windows 8. And as you’ll see in the results below, the emerging OS can hold its head high on several measures of performance.
Startup and Shutdown
One of the most important gauges of speed in a computer is how long it takes to start up and be ready. This is probably one of the main reasons the iPad is so successful—it’s just there and ready to go, no need to wait for a boot process, usually. Not quite as critical, but nevertheless important is the time it takes the computer to shut down. I tested start by timing from the click of the disk boot choice to a functional home screen, with no wait spinner spinning.
For shutdown, I started the timer at the moment of hitting the Shut Down choice, and stopped it when the laptop’s fans went silent. I went through iterations for each, throwing out the high and low results and averaging the remaining five. The surprise here is that Windows 8 starts up significantly faster on a MacBook than OS X Mountain Lion does, though the latter shuts down in half the time of Windows 8. But note that hitting the power button puts Windows 8 into sleep mode, which happens pretty much instantly.
iTunes Ripping Test
A popular app used in both OSes is Apple’s iTunes, and I used this to measure how long ripping a CD (Buena Vista Social Club, to be exact) took in each OS. This test didn’t show much difference between the two OSes, with Lion coming in a scant 5 seconds quicker. It took Windows 8 3:47 to rip the 60-minute disc to 256Kbps M4A tracks, while Lion took 3:42. This one is pretty much a wash, though OS X gets a tiny advantage.
Synthetic Benchmark: Geekbench
Geekbench 2.3, from Primate Labs, is a cross-platform benchmark that runs a series of geeky tests like prime number, Mandelbrot, blowfish encryption, text compression, image sharpen and blur, and memory stream test. The subtests comprise both single- and multithreaded applications. The results are normalized so that a score of 1,000 is the score a Power Mac G5 1.6GHz, so a higher number is better.
I ran both the 32-bit and 64-bit tests in Geekbench three times and took the average for each OS. Though it’s mostly designed to test hardware, it can at least show us whether the OS is getting in the way of accessing the hardware quickly. The result for this benchmark surprised me, with Windows 8 in 64-bit mode taking the crown, delivering a score of 10068 compared with Mountain Lion’s 8706. In the 32-bit version of the test Mac OS S Mountain Lion was actually a bit faster, with a score of 7918 compared with 7549 for Windows 8.
Web Benchmarks
To test with a few popular Web browser benchmarks, I installed Mozilla Firefox on both operating systems so that the browser engine would be less likely to determine the results. But since a case could be made for using the OS’s native browser, I ran the benchmarks in Safari on OS X Mountain Lion and Internet Explorer 10 in Windows 8, too.
The SunSpider JavaScript benchmark is a heavily used measure of a browser’s JavaScript performance, put out by the WebKit organization, which, by the way, makes the rendering engine for Apple’s Safari. Results on this test was comparable with all setups, hovering in the high 150s—with one big exception: It was significantly faster on Internet Explorer under Windows 8, which consistently delivered results closer to 100 milliseconds.
Mozilla’s Kraken 1.1 is another JavaScript benchmark, which the open-source browser maker says represents a more realistic workload. Both OSes were close when running Firefox, with a slight advantage to Windows 8. But when running the native browsers, Windows 8’s IE10 fell far behind Mountain Lion’s Safari 6.
A final browser benchmark, Psychedelic Browsing, from Microsoft’s IE Testdrive site, is designed to test graphics hardware acceleration of Web content. Microsoft has done a ton of work on this acceleration technology, and it shows in the results, using both Firefox and the native browsers.
File Copy Test
For this one, I took a folder containing 20 files weighing in at 636MB, and simply timed how long it took to copy it from a fast USB thumb drive (a 16GB Corsair Flash Voyager GT) to the MacBook running Windows 8 and then Mountain Lion. As when I compared Windows 7 with Windows 8, the operation took a few seconds longer in Windows 8. A Microsoft representative explained to me that this is because “in Windows 8, each file transfer is scanned to ensure there is no malicious code, which takes a little longer but is a better and safer experience for users.”
Windows 8 vs. Mountain Lion
This is hardly an exhaustive comparison of every kind of performance measurement you could want to compare operating systems. And indeed with (in most cases) different software running on each, it’s hard to make direct, apples-to-apples comparisons. But the results do show that, say what you like about features and interface, Windows 8 can hold its head high next to Apple’s newest desktop operating system when it comes to performance. In particular, I was impressed with how quickly Windows 8 started up on my test MacBook, and with its remarkably faster Geekbench (64-bit) and SunSpider (in IE10) performances. And anecdotally, Windows 8 feels snappy. Speed is one thing you won’t have to worry about with Microsoft’s next big operating system.
Mountain Lion, as you’d expect, doesn’t feel like any kind of slouch running on a Core i7 MacBook, either. And you could argue that you’d expect the rich environment of OS X to require more processing than the primary-color simple interface of Windows 8. This is especially true for startup, which has to load more of the rich OS’s features. Mountain Lion’s shutdown time is half that of Windows 8 running on the same machine, and on an independent JavaScript benchmark, Mozilla Kraken, its Safari browser beats Windows 8’s IE10. Finally, Mountain Lion’s faster file-transfer time will be magnified for truly large amounts of data, too.

Proxy free Windows xp/7/8 and Mobiles!

All the methods mentioned below are ethical and your institute should ideally allow them as they need your proxy authentication at some point or the other.

1. CC Proxy

  • Open CC proxy as administrator.
  • Go to Options. A configuration window pops, select your ip from the drop down (Ex: 192.168.2.5 in my case) and check the checkbox right to it
  • Go to advanced (in options)->cascading tab->enable cascading (select all)
  • Enter your server details (Ex: server: netmon.iitb.ac.in, Port : 80) and authentication
  • Open proxy settings in Internet explorer->enter your proxy server as your ip address (192.168.2.5 in my case), port as 808 for all but SOCKS. Enter 1080 for SOCKS
  • Open command prompt as admin user->type this. (Type cmd in search and right to open as admin)
  • Enter this ‘netsh winhttp import proxy source=ie‘ without quotes ofcourse and enter
  • And your DONE!!
For frequent ip changers: Goto Accounts and set,
                                        Permit category: Permit only
                                        Auth Type: IP Address
Select New (in same window) -> Enter IP Range as ‘127.0.0.1’. Ensure Enable and IP Adress are checked.
Now instead of entering ip address in browser or other applications, enter 127.0.0.1
 

This is usually helpful to give an authentication free proxy to mobiles and other gadgets. If it didn’t work for you as is (I know it doesn’t for Windows 8 users), Download the below application and follow the steps. Mobile users scroll down for settings.


Download from http://www.praveenkumar.co.in/#!/Downloads
File name : ‘ccproxysetupfree7.2 .exe’
NOTE: Though it’s a paid software. You can use the free version without registering.

2.EnableLoopbackUtility

This one helps you run your Metro apps (Windows 8) without proxy pains!!
This app can’t do the job by itself. You need CC proxy setup done, for it to work

  • Open the app->After a copy process, press close->A window popsup->Click exempt all->Save changes and you are done !
  • A restart may be needed in some cases.

Download from http://www.praveenkumar.co.in/#!/Downloads
File name : ‘EnableLoopBackUtility.exe’

3.Proxifier

I own no credit about this video or method. This routes all you PC traffic through it with no need of settings in other apps! You can use everything as though you don’t have proxy! Its a paid app btw ;)


Download from http://www.praveenkumar.co.in/#!/Downloads
File name : ‘ProxifierSetup.exe’
NOTE: Its just the setup file. You need to either buy it or use a crack which you have to download seperately. IITB ppl can search for crack on DC as ‘netmon proxy’

-Here is a video which guides you. This video made for IIT Bombay proxy server. You can do it similarly for yours


 
Windows 8 tip
 
It has been noticed, quite often, that windows 8 metro apps won’t work even after following the above steps. Just consider yourself one of those unlucky souls and try this,
 
  • If you see exclamation mark on your LAN connection, right click on that icon and try ‘Troubleshoot problems’. It may work if the mark goes away.
  • Still not working ? You hit the jackpot :P It may take a couple of restarts. Don’t panic ! It will work on someday. There is nothing much I can comment on this particular behavior.
 
 
Mobile settings 
If you running on Android 4.0 or higher (works for windows phones also) and want to use institute LAN speeds without having to root follow this.
 
  1. Setup CCProxy as mentioned above
  2. Create a WiFi hotspot, either using connectify or without any third party software from here
  3. While connecting to the hotspot created above, go to advanced options while entering WiFi password
  4. Change proxy settings to manual and for host, enter <ip> you gave in CCProxy setup and the port as 808.

Google Play Store now has Smart Delta App Updates [Download updated parts of apps only]

At Google I/O the company announced that the Google Play Store would be getting the ability to offer delta smart updates for apps, so that you wouldnt have to download an entire app again whenever it got an update.
This is a move that will save tons of people a lot of data, especially considering scenarios like how a game like Asphalt which weighs in over 1GB, can get an update with just two new cars, for which you will have to download the entire 1GB game update. Saving time and bandwidth, the Play Store will only download the actual changes of an app instead of the entire program or game. Very useful if you’re on a limited data plan.
Smart app updates is a new feature of Google Play that introduces a better way of delivering app updates to devices. When developers publish an update, Google Play now delivers only the bits that have changed to devices, rather than the entire APK. This makes the updates much lighter-weight in most cases, so they are faster to download, save the device’s battery, and conserve bandwidth usage on users’ mobile data plan. On average, a smart app update is about 1/3 the size of a full APK update.
