Google play HACKED!

Hello Google.

My name is Marcin Grygiel.
When I am bored, I do strange things…
I take a bath with my cat,
I have Nexus 5 running Windows 7
and now I accidentally hacked Google play.

I think you can hire me!

4x Radeon HD 7990 Mining Monster Rig (8 GPUs)

Cryptocurrency is a type of digital currency that is based on cryptography. Cryptocurrency uses cryptography for security, making it difficult to counterfeit. Public and private keys are often used to transfer the currency from one person to another.

Cryptocurrency is considered a counter-culture movement related to cypherpunks, who advocate the use of cryptography as a route to social and political change. Cryptocurrency presents a form of this movement in that it is essentially a fiat currency, which means it only has value if people agree to such and use it as a medium of exchange. However, because it is not tied to any country, its value cannot be affected by a central bank. In the case of Bitcoin, the most prominent functioning example of cryptocurrency, its value is determined by supply and demand in the market. As such, this currency behaves much like gold and other precious metals.

Memory Usage: Android 4.2.2 vs Windows 8.1

This result may be surprising to many Android users.
It’s just that Android 4.2.2 (Jelly Bean) uses more memory than desktop version of Windows 8.1 x64 RTM, but unlike Windows 7 and 8, Windows 8.1 requires more memory to start up.

If you remember, I was able to run both Windows 7 and Windows 8 on 128MB of RAM. However, Windows 8.1 requires 256MB to boot (at least running stable), 512MB for installation and 1gig to run comfortably.

Impressive, isn’t it? 😉

Why I hate HP laptops?

Fortunately, I never bought any HP laptops but I have fixed a lot of them, for my friends. I don’t know about the new models, but I suppose they didn’t change much on that –  moreover, new laptop prices drop every year!

Reasons why NOT to buy a HP laptop:

  1. Broke soon after warranty expired!
  2. All HP laptops have a bad design for cooling!
  3. HP loves pre-installed Bloatware & Crapware
  4. They’re more expensive than other good brands.

Today I bought Corsair Vengeance 16GB Quad Channel DDR3 Memory Kit and decide to break some benchmark records. I’m not using Liquid Nitroge only water cooler with custom fans.
It will be really hard to get to the Top 20 Resultshwbot.org

Before we look at the numbers, let’s take a brief look at the test system that was used. All testing was done on Windows 8 Pro 64-bit operating system.

Why So Serious?

Do you think it is safe to leave me alone with random terminal?
The right answer… is NO! BTW, I use built-in camera 😀
This was Windows XP with Active Directory authentication.
Do not worry if there is a bug, I will find it and use it!

  • Hacking (thinking) Time – 5 minutes
  • Make Up Time – 15 minutes

Keep Calm and Hack The Planet

I just think it takes slightly too long… I’m waiting 8 months, by the time my website has been visited over 700 times by LAPD. If you can’t hack you own Windows Vista, 7 or 8 then solve the Quiz! 😀
Try to use your brain it won’t hurt much.
