Shutting Down your Windows PC without a software

Most of us will want their PC's to go to sleep or hibernate or even shutdown automatically at specified time. Maybe cause you had been listening to some cool music and you fell asleep, you would want your machine to also shutdown. What most of us do is download a software created by another person, preferably a geek and run it with ease not knowing thats just a bunch of dos commands scripted into a batch script and fed into the system log. But ever thought how simple that was? well this post explains that.
The Process
1. simply open up Run by pressing windows+r
2. type in the following: at 23:59 shutdown -s   then press enter

    This will shut your PC at 11:59 pm i tell you...
To get of this timing simply open run once again and type the following command

     shutdown -a

SQL SYNTAX

SQL that stands for Structured Query Language...And what we read as S - Q - L instead of Sequel is an advanced relational database system that offers a robust environment to allow for organization to store their information in a secure manner. Not putting into effect its largest competitor, the Oracle Database.
However, both languages have almost similar syntax, this should not be a confusing factor that learning SQL means you understand Oracle, rather learning SQL makes you understand database manipulation methods that could be used in oracle too.
Before SQL, people would use Microsoft Access that offered an intuitive simple interface for most individuals to work with.
Many powerful tasks can be performed in SQL by use of its mere seven powerful statements:
SELECT
INSERT
UPDATE
CREATE
ALTER
DROP, and
DELETE
The above statements fall under two major categories:
DATA MANIPULATION LANGUAGE (DML), and
DATA DEFINITION LANGUAGE(DDL)

DML:
SELECT- used to select data in one or more columns of one or more tables
INSERT - allows you append rows to an existing table
UPDATE - allows you to update data in one or more rows of one or more tables
DELETE - allow you delete one or more rows from a table or multiple tables

DDL:
 CREATE - enables you create new table, or create new index
ALTER - enables you modify structure of existing table thro adding and deleting columns
DROP - enables you delete a table or a database

The next tutorial will be on using the DML and DDL'S

Li-Fi

Am sure ave been dormant in this platform but to begin with here is my new recent post
Most of us know of the Wi-Fi technology, bluetooth, radio, eye-fi, Hi-fi among other wireless technologies. But thanks to China's new invention. A new technology is here - Li-fi is a wireless technology that employs the light bulb technology to transmit wireless internet connectivity.


Li-fi was first demonstrated by University of Edinburgh professor Harald Haas in the UK. At an Aug. 2011 TED Talk, Haas displayed a li-fi device transmitting at 10 Mbps, asserting that the technology could hypothetically exceed 1 Gbps. The Fraunhofer Heinrich Hertz Institute confirmed this claim earlier this year, according to the BBC.
The technology relies on a fast-pulsating beam of light embedded with signal processing technology. Receiving devices would read the light pulses and translate them on a streaming basis. On-board cameras in smartphones, tablets, computers and other gadgets could be modified to double as photoreceptors.
If the technology proves viable, it could make for a cost-effective, highly efficient, high-speed networking medium. Due to the fact that it relies on direct light, its use as a secure data line could be useful in privacy-dependent scenarios.

Disabling The USB Port

       Ever feel furious of the many USB flash drives and SD cards that are the unending cause of viruses and malware in your system? It's very possible to disable USB port recognition by simply tweaking the registry as below:

 1. Goto run

2. Type 'regedit' without quotes

3. Click on HKEY_LOCAL_MACHINE

4. goto SYSTEM

5. Click on CurrentControlSet

6. Click on services

7. Goto USBSTOR

8. Double click on 'Start' where value is 3

9. Now change the value data with 4

10. Now press ok and refresh your desktop your USB port is disabled, to enable the usb port replace the value 4 with 3.

How does a touchscreen work?

   Ever wondered how your touchscreen accepts the commands that you want it to undertake just by the touch of it using your finger or just using a stylus or some other stuff? And OOOww not all phones can accept both a stylus and a finger, some only accept finger touch while others the pen touch...
  Well below is an explanation of how all that stuff works courtesy of    #Hack_The_ universe

How Touchscreen Works ??

A touchscreen is an electronic visual display that the user can control through simple or multi-touch gestures by touching the screen with one or more fingers. Some touchscreens can also detect objects such as a stylus or ordinary or specially coated gloves.

Touchscreens are common in devices such as game consoles, all-in-one computers, tablet computers, and smartphones. They also play a prominent role in the design of digital appliances such as personal digital assistants (PDAs), satellite navigation devices, mobile phones, and video games.

Working of Touch Screen Are very Interesting. Here's How they Work:

There are three basic systems of Touch Screen:
1. Resistive System
2. Capacitive System
3. Surface Wave acoustic

The RESISTIVE SYSTEM consists of a normal glass panel that is covered with a conductive and a resistive metallic layer. These two layers are held apart by spacers, and a scratch-resistant layer is placed on top of the whole setup. An electrical current runs through the two layers while the monitor is operational. When a user touches the screen, the two layers make contact in that exact spot. The change in the electrical field is noted and the coordinates of the point of contact are calculated by the computer. Once the coordinates are known, a special driver translates the touch into something that the operating system can understand.

Working Of Resistive Touch Screen !!!

In the CAPACITIVE SYSTEM, a layer that stores electrical charge is placed on the glass panel of the monitor. When a user touches the monitor with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases. This decrease is measured in circuits located at each corner of the monitor. The computer calculates, from the relative differences in charge at each corner, exactly where the touch event took place and then relays that information to the touch-screen driver software. One advantage that the capacitive system has over the resistive system is that it transmits almost 90 percent of the light from the monitor, whereas the resistive system only transmits about 75 percent. This gives the capacitive system a much clearer picture than the resistive system

Working Of Capacitive Touch Screen !!!

The SURFACE WAVE ACOUSTIC SYSTEM works with help of wave energy. This enables a touch to transform into another form of energy and deliver the command which in response perform the desired action. A Pair of transducers is placed on glass plate sides. In the Glass Plates there are reflectors. On touching the screen wave produced and which transforms into energy for fulfilling the command. It tells where on the screen touch is detected.
