Good new ; Cheaper Solid-State Drives (SSD) back to use

A few months ago while I was troubleshooting an Assus laptop, I noticed that they have actually switched their storage systems  to SSD after the hassles of identifying the widely known PATA/IDE/SATA HDD .





Currently, Flash based memory larger USB Memory sticks with spaced capacities, can be used to read and write data instead of the old drives where a magnetic head reads and writes across platters of spinning disks.

SSD Drives have been used in Military and Airline applications for years, now the price has dropped to allow them to be a viable option for home and business users.

They are more reliable, faster, and more durable than traditional magnetic hard drives. They consume less power which is a primary reason why they are widely used in Netbooks and Laptop/Notebooks.

With the larger sizes of SSD over memory sticks, and the ability to connect them using SATA, PCI Express you can easily have a drive inside your machine.Or turned into a light, fast portable drive (with additional kit) which wont mind the odd knock unlike 2.5/3.5" mechanical drives.

Double Whatsapp in smartphones.

Lately I have been running two whatsapp  in my droid.
This is possible by installing a version, I term it as modded  We have several modded versions of whatsapp and other apps but I always give you what i have tried.

1. Download Ogwhatsapp.


Its features are as shown in this other image.



































Thank you for your time.

Interior designs

I won't write a lot, I will just pick a few of my work , do I call it portfolios . This is a small presentation of how architectural plan can be taken to a full level of interior designing an furnishing.

1. Plan with dimensions.




















I should have taken a shot before furniture placement and floor cover.

2. The aerial over-view.


This is a simple as it is in 2 hrs time.

3.View when walls are disabled (This is a software option for layout views).




From this point we can view furniture and manuver around to check flaws.

5. The sitting room.

Now you can get closer. I have switched on the lights. Did you notice the illumination?

6. The Kitchen.

I did not want to get in there, the kitchen was a bit smaller to capture all the serenity. In the kitchen is a cooker, fridge , sink and fire place. If you were keen enough , this flower pot on our left is the one in the kitchen entrance in previous picture.

7.The master Bedroom.


I did not add a lot of things in the room. ha-ha like shoes and other stuff. The door to the left leads us to the bathroom. In the bathroom is a water tab, water-let loo and a sink.

FOR THIS AND BIGGER WORKINGS .

Safaricom Leaked Data Bundles Frauds.

Safaricom, Ltd is a leading mobile network operator in Kenya.It provides telecommunication services including cellular network provision , internet services to homes and offices, mobile banking and others.

Safaricom provides internet data to its mobile subscribers. In this way ,as a carrier user, you purchase your data bundle through credit cards , online services, the mobile banking service dubbed M-pesa or get subscriptions depending on your plan.

This telecommunication company is one of the most preferred providers by the citizens and covers most of the countries network system.

Cause of the blunder.

Late in 2014 and early this year , Safaricom sold out some brands of mobile phones and smartphones in their outlets and care centers,e.g Samsung , Nokia ,Techno and Alcatel includes others . This kind of purchase was given out with customers promotions of free airtime and data bundles. Before customers were given this promotions , they used their purchased mobiles EMEI numbers to verify grants of promotions.

Concept of the fraud.

This is where everything become a fraud, technology enthusiasts thought further and dug out how the mobile brand suppliers generate their EMEI  numbers. They then used one valid EMEI address from the vendor to calculate and generate EMEI addresses of corresponding mobile phone produced at a particular time . This mobile brands manufacturers may have sold out this phones in bulk and this made every EMEI calculation SUCCESSFUL.

Fraud Accelerated.

When the fraudsters had identified the formula to generate this EMEI  addresses , an android application was written to ease out  calculations and this turned alarming to Safaricom.

The Theory Behind. (Formula)

The formula that is used by most mobile manufacturers to assign EMEI addresses to every devise is called The Luhn algorithm or Luhn formula . 
As summarized bellow , it is used to generate a code that exits in an encrypted sequence.

System on a chip (SoC)

This is really interesting, a small component that executes multiple tasks in an intelligent procedure.An SOC is simply a micro controller mostly used in smartphones.

 
(SOC - On fingers)

In reference to Wiki, A system on a chip or system on chip (SoC or SOC) is an integrated circuit (IC) that integrates all components of a computer or other electronic system into a single chip.

 It may contain digital, analog, mixed-signal, and often radio-frequency functions all on a single chip substrate. SoCs are very common in the mobile electronics market because of their low power consumption. A typical application is in the area of embedded systems.

What makes me curious on this issue is the design and the know how that requires one to make a system of such intelligence and capability.The following is an over view of its interior with functions.



This processors are widely known by the following brands
  • Intel
  • AMD
  • Qualcomm
  • Mediatek etc.
