Simple Drop Down Menu with Jquery and CSS

2015-01-06T06:09:00.001-08:00

Making an drop down menu is very basic lessons to jquery. It includes css tricks. Actually drop down menu is a kind of menu when mouse click is clicked over a link. It shows a list of menu when link is clicked. Here we need to design a div to show menu and another element to show menu link. It is very simple to design.Lets take a look at how to do that.

DROP DOWN MENU

Take a look at various steps to make drop down menu:-

STEP-1

First I will show you the html codes.

<div class="mainmenu">
<a class="shop" >Shop</a>

<div class="submenu">
<ul class="list">
<li ><a href="#categories">CATEGORIES</a></li>
<li ><a href="#clothing" >Clothing</a></li>
<li ><a href="#homegoods">Home Goods</a></li>
<li ><a href="#bedroom">Bedroom</a></li><hr/>
<li ><a href="#bedroom">ORDER</a></li>
<li ><a href="#status">Status</a></li>
<li ><a href="#cancel">Cancellations</a></li>
</ul>
</div>

</div>

STEP-2

Contains javascipt code. $(".shop").click(function(){}- here shop is the class name of the main menu (shop) anchor tag. Using $(this).attr('id') calling id value of the anchor tag and based on condition showing .submenu div box and the same time $(this).attr('id', '1') adding id value too.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js">
</script>;
<script type="text/javascript" >
$(document).ready(function()
{

$(".shop").click(function()
{
var X=$(this).attr('id');
if(X==1)
{
$(".submenu").hide();
$(this).attr('id', '0');
}
else
{
$(".submenu").show();
$(this).attr('id', '1');
}

});

//Mouse click on sub menu
$(".submenu").mouseup(function()
{
return false
});

//Mouse click on shop link to show submenu
$(".submenu").mouseup(function()
{
return false
});

//Document Click, Means when there is click on the other part of the web page. Here document is for web page
$(document).mouseup(function()
{
$(".submenu").hide();
$(".submenu").attr('id', '');
});
});
</script>

STEP-3

Now everything is done. You just need to add some css codes to make effective and good looks of the drop menu. So here's the code-
.mainmenu
{
color: #555;
margin: 3px -22px 0 0;
width: 143px;
position: relative;
height: 17px;
text-align:left;
}
.submenu
{
background: #fff;
position: absolute;
top: -12px;
left: -20px;
z-index: 100;
width: 135px;
display: none;
margin-left: 10px;
padding: 40px 0 5px;
border-radius: 6px;
box-shadow: 0 2px 8px rgba(0, 0, 0, 0.45);
}
.mainmenu li a
{
color: #555555;
display: block;
font-family: arial;
font-weight: bold;
padding: 6px 15px;
cursor: pointer;
text-decoration:none;
}

.mainmenu li a:hover
{
background:#155FB0;
color: #FFFFFF;
text-decoration: none;
}
a.account
{
font-size: 11px;
line-height: 16px;
color: #555;
position: absolute;
z-index: 110;
display: block;
padding: 11px 0 0 20px;
height: 28px;
width: 121px;
margin: -11px 0 0 -10px;
text-decoration: none;
background: url(icons/arrow.png) 116px 17px no-repeat;
cursor:pointer;
}
.list
{
list-style:none;
margin:0px;
padding:0px;
font-size: 11px;
padding: 11px 0 0 0px;
border-top:1px solid #dedede;
}

Great you have done it. Thank You ! If you have any query related to anything ask here.

How to create tab style boxes in html using jquery and css ?

2015-01-04T23:25:00.000-08:00

Making multiple stylish boxes in tag style using jquery and css is so easier. It does not require so much of area in your blog or website. Read More about it in w3cschools website.

This post is very basic level CSS implementation. I want to explain how to design tab style two boxes with CSS, HTML and Jquery. In maximum cases the tabbed boxes are used for login and registration purposes and can be used for many other purposes are also like in blog many times three tabbed boxes are used.

STEPS TO MAKE TABS

STEP -1

1. First we need to create boxes using div. Layout divided into three horizontal parts are main, Tabbutton and show. Here main is the parent div.

.So here's the css codes

#main

{

width:350px;

background-color:white;

border:none;

}

#tabbuttons

{

height:50px;

}

#show

{

height:300px;

background-color:white;

border:none;

}

STEP-2

Now the div box tabbuttons divided into two another boxes. You can give any names to them according to your need. For example i am going to give them two names is 'panel1' and 'panel2'.

As shown below :-

Now we need to enter html codes

These are the html codes for tabuttons only

<a href="#" id="panel1" class="tab link">Pannel 1</a>

<a href="#" id="panel2" class="tab select">Pannel 2</a>

</div>

STEP-3

Now th CSS codes for tabs

Contains CSS3 code for round corners. Here link class for margin left 8px it allots gap between panel1 and panel2 tabs.

.tab
{
background: #dedede;display: block;height: 40px;
line-height: 40px;text-align: center;
width: 80px;float: right;font-weight: bold;
-webkit-border-top-left-radius: 4px;
-webkit-border-top-right-radius: 4px;
-moz-border-radius: 4px 4px 0px 0px;
}
a
{
color: #000;
margin: 0;
padding: 0;
text-decoration: none;
}
.link
{
margin-left:8px;
}
.select
{
background-color:#FFF;
}

STEP-4

Now Panel div divided into two horizontal parts are panel1box and panel2box. By default pannel2box display none.

<div id="pane1box"> USER CAN ADD ANY CONTENT HERE </div>

<div id="pane2box"> USER CAN ADD ANY CONTENT HERE </div>

</div>

CSS codes for panel boxes
#loginbox
{
min-height:200px;
padding:10px;
}
#signupbox
{
min-height:200px;
padding:10px;
display:none;
}

STEP-5

Now everything designing and css work has been done now its turn for jquery to show its magin to handling the DOM objects.

what we need to do is -

Top eight special forces in the world !

2015-01-04T03:02:00.000-08:00

Top Ten Special Forces in the world !

For Details study Wikipedia

Today we gonna tell you about the world's best special forces ever. Special Forces are required for the special operations. For example during the mumbai attacks in India 2008. Special Forces of India perform the action and killed the terrorists and caught up the one terrorist alive named Ajmal Kasab.

Countries throughout the world train special operation forces within their military, so coming up with a list of top special operations forces in the world is difficult at best.

All special ops forces train their military men to be the best of the best, to take the impossible task and make it possible. In that respect, all Special Operations units are top. Special forces, or special operations forces are military units extremely trained to perform unconventional, typically insecure missions for a nation’s political, economic or military purposes.

Here is the list of top 8 Special Forces of the world !

8. MARCOS (INDIA)

The MARCOS (Marine Commando Force) is an elite special operations unit of the Indian Navy. It was created for conducting special operations such as Amphibious warfare, Counter-terrorism, Direct action, Special reconnaissance, Unconventional warfare, hostage rescue, Personnel recovery, Asymmetric warfare, Counterproliferation. The MARCOS is specially organised, trained and equipped for the conduct of special operations in a maritime environment. It is recently active in Indian Ocean to protect their homeland.

7. NSG (PAKISTAN)

The SSG (Special Services Group) is a special operations force of the Pakistan Army. It is quite similar to the U.S. Army’s Special Forces and the British Army’s SAS. The unit was created in 1956, it also known as “Black Storks” a name derived from their unique headgear the “Maroon Beret”. The SSG considered one of the world’s best special forces because of their courage and bravery. As a Russian president once said that if he had Pakistan’s army and Russian weapons he could conquer all the world because they are very brave.

6. NSG (INDIA)

The National Security Guard (NSG) is one of the eight Central Armed Police Forces of India raised "for combating terrorist activities with a view to protect States against internal disturbances".^[1] It is one of the eight Central Armed Police Forces under the Government of India, Ministry of Home Affairs. The NSG has two components, the Special Action Group (SAG), which consists entirely of army personnel; and the Special Ranger Groups (SRG), which comprises personnel drawn from the other Central Armed Police Forces and State Police Force. The head of the force, designated as a Director General, who wears the same badges of ranks as an army Lieutenant General, is an officer from the Indian Police Service^.

5. JW GROM, Poland

The JW GROM (Jednostka Wojskowa GROM) is Poland’s elite counter-terrorism unit. The unit was officially activated on July 13, 1990 in response to terrorist threats. GROM, which stands for “thunder” is one of the five special operation forces units of the Polish Armed Forces. They are trained to respond to a variety of threats and unconventional warfare roles, including anti-terrorist actions and projection of power behind enemy lines.

4. GSG 9, Germany

GSG 9 is a German counter-terrorism and special operations unit of the German Federal Police. It was officially established in 1973 after the mismanagement of the German Police to successfully free 11 Israeli athletes who were kidnapped in Munich during the Summer Olympic Games. GSG 9 is deployed in cases of hostage taking, kidnapping, terrorism and extortion. It also be used to secure locations, neutralize targets, track down fugitives and sometimes conduct sniper operations. The unit is very active in developing and testing methods and tactics for these missions. From 1972 to 2003 they reportedly completed over 1,500 missions,[1] discharging their weapons on only five occasions.

3. Delta Force, United States

1st Special Forces Operational Detachment-Delta (1st SFOD-D), popularly known as Delta Force, was officially approved in 1997 after numerous, well-publicized terrorist incidents in USA. It’s the best and one of the most secretive forces in the US. Modeled after the British 22 Special Air Service Regiment, or SAS. The founder/co-founder of SFOD-D was a former SAS operative who thought the US needed an elite force like the SAS. Delta Force’s primary tasks are counter-terrorism, direct action, and national intervention operations, although it is an extremely versatile group capable of conducting many types of clandestine missions, including, but not limited to, hostage rescues and raids.

2. Navy SEALs, United States

The Navy SEALs, also known as the United States Navy’s Sea, Air and Land Teams can trace their roots to World War II. SEALs are male members of the United States Navy, and are one of the United State’s most elite special Warfare Combatants. The CIA’s highly secretive Special Activities Division (SAD) and more specifically its elite Special Operations Group (SOG) recruits operators from the SEAL Teams. Joint Navy SEALs and CIA operations go back to the famed MACV-SOG during the Vietnam War. This cooperation still exists today and is seen in the wars in Iraq and Afghanistan. Most recent joint Navy SEALs and CIA operation in the finding and killing of Osama bin Laden in Pakistan.

1. SAS, United Kingdom

Special Air Service is one of the best Special Forces in UK. SAS was set up in 1941 during the Second World War and has served as a model for Special Forces around the world. It was reformed as part of the Territorial Army in 1947, and named the 21st Battalion, SAS Regiment. The Regular Army 22 SAS gained worldwide fame and recognition after successfully attacking the Iranian Embassy in London and rescuing hostages during the 1980 Iranian Embassy siege. It currently comprises one regular regiment and two territorial regiments. It,s primary tasks are counter-terrorism in peacetime and special operations in wartime.

Comparison of India and pakistan on the basis of weapons ?

2015-01-04T00:36:00.001-08:00

Comparison of India and Pakistan on the basis of weapons !

India and Pakistan have long engaged in wars, largely due to a territorial dispute in the Kashmir region. Originally, the conflict began when the subcontinent was divided after World War II for the sole purpose of separating Muslims from the Hindus. However, this division was not as effective as it was foreseen, and the long and bloody series of the Indo-Pakistani conflicts began.

In almost all aspects, India holds the upper hand; numerically, technologically, and economically, India is significantly superior to Pakistan. India is the world’s number one buyer of arms and weapons from a variety of contractors and manufacturers from the US, UK, China, Russia, and several others.

How to fix div element after some scrolls ?

2015-01-03T20:30:00.000-08:00

Fix div element after some scrolling

As we see on maximum websites, after some scrolling any specific div element get fixed may be situated in sidebar left or right. This is due to a simple jquery trick. It uses css elements to detect the

scroll position.

So Do that what we have to do :-

You need a div element which you want to fix.For example -

#sidebar_lower
{
width:300px;
height:600px;
background-color:white;
box-shadow:0 0 3px silver;
border:1px solid silver;
margin:2px;
padding:7px;
}

And also need a div class to use during that operation :-

.sticky {
position: fixed !important;
z-index: 1000;
}

And all you have done about css.

Now its Jquery work

In jquery you need to add following codes :-

$(document).ready(function() {
var stickyNavTop = $('#sidebar_lower').offset().top;

var stickyNav = function(){
var scrollTop = $(window).scrollTop();

if (scrollTop > stickyNavTop) {
    $('#sidebar_lower').delay(20000).addClass('sticky');
} else {
    $('#sidebar_lower').removeClass('sticky');
}
};

stickyNav();

$(window).scroll(function() {
    stickyNav();
});
});

</script>

here sticky class is used to fix the position of div element.

Technology Behind the Guided Missiles !

2015-01-03T19:28:00.001-08:00

Technology Behind the Guided Missile System !

Liftoff of Missile.
Missiles are generally categorized by their launch platform and intended target. In broadest terms, these will either be surface (ground or water) or air, and then sub-categorized by range and the exact target type (such as anti-tank or anti-ship). Many weapons are designed to be launched from both surface or the air, and a few are designed to attack either surface or air targets (such as the adats missile). Most weapons require some modification in order to be launched from the air or surface, such as adding boosters to the surface-launched version.

Various Components of a missile :-

There are different components which are used by a missile to reach its target are given below:-

Targeting and/or guidance system
Flight system
Engine
Warhead

Guidance system

Missiles may be targeted in a number of ways. The most common method is to use some form of radiation, such as infrared, lasers or radio waves, to guide the missile onto its target. This radiation may emanate from the target (such as the heat of an engine or the radio waves from an enemy radar), it may be provided by the missile itself (such as a radar) or it may be provided by a friendly third party (such as the radar of the launch vehicle/platform, or a laser designator operated by friendly infantry). The first two are often known as fire-and-forget as they need no further support or control from the launch vehicle/platform in order to function. Another method is to use a TV camera—using eithervisible light or infra-red—in order to see the target. The picture may be used either by a human operator who steers the missile onto its target, or by a computer doing much the same job. One of the more bizarre guidance methods instead used a pigeon to steer the missile to its target.

Many missiles use a combination of two or more of the above methods, to improve accuracy and the chances of a successful engagement.

Targeting system

Another method is to target the missile by knowing the location of the target, and using a guidance system such as INS, TERCOM or GPS. This guidance system guides the missile by knowing the missile's current position and the position of the target, and then calculating a course between them. This job can also be performed somewhat crudely by a human operator who can see the target and the missile, and guides it using either cable or radio based remote-control, or by an automatic system that can simultaneously track the target and the missile. Furthermore, some missiles use initial targeting, sending them to a target area, where they will switch to primary targeting, using either radar or IR targeting to acquire the target.

Flight system

Whether a guided missile uses a targeting system, a guidance system or both, it needs a flight system. The flight system uses the data from the targeting or guidance system to maneuver the missile in flight, allowing it to counter inaccuracies in the missile or to follow a moving target. There are two main systems: vectored thrust (for missiles that are powered throughout the guidance phase of their flight) and aerodynamic maneuvering (wings, fins, canards, etc.).

Engine

Missiles are powered by an engine, generally either a type of rocket or jet engine. Rockets are generally of the solid fuel type for ease of maintenance and fast deployment, although some larger ballistic missiles use liquid fuel rockets. Jet engines are generally used in cruise missiles, most commonly of the turbojet type, due to its relative simplicity and low frontal area.

Turbofans and ramjets are the only other common forms of jet engine propulsion, although any type of engine could theoretically be used. Missiles often have multiple engine stages, particularly in those launched from the surface. These stages may all be of similar types or may include a mix of engine types - for example, surface-launched cruise missiles often have a rocket booster for launching and a jet engine for sustained flight.

Warhead

Missiles generally have one or more explosive warheads, although other weapon types may also be used. The warhead or warheads of a missile provides its primary destructive power (many missiles have extensive secondary destructive power due to the high kinetic energy of the weapon and unburnt fuel that may be on board). Warheads are most commonly of the high explosive type, often employing shaped charges to exploit the accuracy of a guided weapon to destroy hardened targets. Other warhead types include submunitions, incendiaries, nuclear weapons, chemical, biological or radiological weapons or kinetic energy penetrators. Warheadless missiles are often used for testing and training purposes.

How are the Indian Special Forces like NSG, MARCOS, and Garud Commandos are trained ?

2015-01-03T06:12:00.001-08:00

These are the information about the Indian Special Forces Training.

1)NSG (National Security Guards) :-

Selection is demanding and has a drop out rate of about 50– 70%.Three of their 14 months of training in Manesar, Haryana, are devoted to the basics.The basic training period lasts 90 days. Physical fitness training has 26 elements, ranging from an cross-country obstacle course to jumping from heights and across divides and scaling different kinds of terrain. One endurance test involves target shooting at the end of an obstacle-ridden cross-country run. This is meant to gauge the candidate’s performance under conditions of stress and exhaustion. Those who successfully complete the tests are sent for nine months of advanced training. The advanced training includes unarmed combat, knife combat, intelligence gathering, surveillance, demolition techniques, specialized insertion techniques, rapid and reflex shooting, mirror shooting etc. Only those who complete the entire course successfully are inducted into the NSG and given further specialised training, thus making them at par with the best forces around.

At the training, the commandos are trained to handle sophisticated communication equipment, combat gadgets and different kinds of arms/specialised weapons such as AK-47/74s, Browning hi-power 9mm pistol, 9mm Uzi sub-machine gun, 5.56mm M-16 A2, 9mm H&K MP5-A2/A3 and locally manufactured 7.62mm SLR and 5.56mm INSAS rifles. Sniper rifles such as the semi-automatic H&K 7.62mm PSG-1 and MSG-90, the SIG 7.62mm, SSG-2000 and the bolt-action Mauser SP66/86SR are also used to train members of the Special Action Group, which is specifically deployed for anti-terror/anti-hijacking operations.

2)MARCOS-

All MARCOS personnel are males selected from the Indian Navy. They are selected when they are in their early 20s and have to go through a stringent selection process and training. The selection standards are extremely high. The training is a continuous process. American and British special forces assisted in the initial training, which now consists of a two-year course for new recruits. The training regiment includes: airborne operations, combat diving courses, counter-terrorism, anti-hijacking, anti-piracy operations, direct action, infiltration and exfiltration tactics, special reconnaissance, unconventional warfare training etc. Majority of the training is conducted at INS Abhimanyu which is also the home base of MARCOS.

All MARCOS personnel are freefall qualified (HALO/HAHO). A few also qualify to operated the Cosmos CE-2F/X100 two-man subs. MARCOS train along with the Special Forces officers of the Indian Army like the Para Commandos at the Indian special forces training school, Nahan and Army's other schools for Unconventional warfare These include the Junior Leaders' Commando Training Camp in Belgaum, Karnataka, the Parvat Ghatak School (for high altitude mountain warfare) in Tawang Arunachal Pradesh, Desert warfare school in Rajasthan, the High Altitude Warfare School (HAWS) in Sonamarg, Kashmir and the Counter-insurgency and Jungle Warfare School (CIJWS) in Vairengte, Mizoram. These elite schools routinely host students from other countries. MARCOS are then trained at various training agencies within the navy. They are skilled combat divers and parachutists and most of the training deals with counter-terrorist, anti-hijacking and anti-piracy operations.

Generally, the pre-training selection process is made of two parts. Any Indian Navy personnel who wants to join this outfit must first undergo a three-day long, physical fitness test and aptitude test. Within this process, 80% of the application are screened out. Further screening process is known as 'hell's week'. This is actually a five-week long process which involves high degree of physical exercises and sleep deprivation. It is only after this process that actual training begins.

The total duration of training of MARCOS is between two and half to three years. The basic training lasts six months. The first two months is the weeding out phase. The first phase of which lasts one month, in which they undergo many rigorous physical tests of which only 50% pass. Then for the next nine months, they are taught how to use different types of weapons, conduct special warfare techniques and how to gather intelligence from the enemy. The cadets start with basic diving and commando tactics and skills. Those that go on are trained in every aspect of modern warfare and in every situation. This includes firing while lying down, standing, running full-sprint, even backwards and looking into a mirror – with a reaction time of 0.27 seconds. This is followed by a year of training of specialised skills. They are trained in various types of close combat including Krav Maga. Different forms of warfare training is imparted through field operations in counter-insurgency and anti-terrorist operations within the country and are trained to operate in any kind of environment like beaches, deep sea, on the surface of the ocean, in jungles, ravines and for situations like hostage rescue, urban combat and piracy. A notably rigorous training program is the "death crawl" – an 800-metre struggle through thigh-high mud, loaded with 25 kg of gear and after a 2.5 km obstacle course that most soldiers would fail. After that, when the trainee is exhausted and sleep-deprived, he has to undergo the final test – shooting a target 25 metres away, with a partner standing next to it.

The MARCOS are trained in every kind of weapon and instruments, from knives and crossbows to sniper rifles, handguns, assault rifles, submachine guns and bare hands. Being divers, they can reach hostile shores swimming underwater.

The further training includes:

Open and closed circuit diving
Basic commando skills including advanced weapon skills, demolitions, endurance training and martial arts
Para training
Intelligence training
Operation of submersible craft
Offshore operations
Anti-terrorism operations
Operations from submarines
Skydiving
Various special skills such as language training, insertion methods, etc.

Explosive ordnance disposal techniques
They are also trained to parachute into open water with full combat load. In 2013, the MARCOS have introduced a larger duck-drop system which will be fitted on Ilyushin Il-76 aircraft. Each system (two boats) can accommodate 32 commandos, their weapons and fuel for the boats. Duck-drop system that marcos operate in the past is smaller in size which is fitted on An-32 aircraft. This force-multiplier was developed by the Agra-based Aerial Delivery Research & Development Establishment. Once para-dropped from the aircraft, it allows for the commandos to assemble inflatable motorised boats within ten minutes, and quickly reach ships in distress. On reaching the target, they can dismantle the boats and travel underwater to mount a surprise attack. Such rescue missions can be mounted by the commandos deployed within an hour unlike in the past, when commandos took up to 48 hours to reach the targets as it involved travelling on-board ships and then being deployed on motorised boats.

The Marcos are also preparing for urban warfare and have begun practicing on 3D virtual models of offshore installations to ensure a swift response during a terrorist attack. The marine commandos are undergoing regular training sessions in this computer-generated programme to be well-prepared for a strike similar to the 26/11 attack. Reliance Industries Limited (RIL) has provided a virtual model of its facility in Krishna-Godavari basin in the east, for the marine commandos at INS Kalinga, the training base for Marcos in Visakhapatnam.

MARCOS will carry out amphibious operations at Frasersgunj in the Sunderbans as part of their routine training. Frasersgunj, with its beach and proximity to the estuarine delta, is an ideal location for such exercises, the source added. The Coast Guard is in the process of setting up a base at Frasersgunj and station hovercraft there. More importantly, the elite force will get a feel of the Sunderbans, which is considered at risk from infiltrators and terrorists. There are so many waterways running through the Sunderbans delta that it is not possible to maintain physical vigil on all movement there. Security experts believe that the threat from terrorists moving in from the sea still remains. With so many vessels passing through the Sunderbans, it may be a route for terror outfits to send in armed men to carry out an attack like that on Mumbai. In case of any eventuality, the Macros are most likely to be called in as it is a marine environment. A major part of their training is kept under wraps. Frasersgunj will be an ideal location where secrecy can be maintained.

The Indian Navy initiated the process of procuring five midget submarines for Marine Commandos (MARCOS). These vessels would have the capacity of carrying four to six personnel on board. The submarines would have a diving depth of around 400 meters, and will strengthen the MARCOS ability to carry out special underwater operations in high seas. The midgets will have the capability of carrying out both manned and unmanned operations and will be equipped with a number of weapons including torpedoes. In 2009, the navy initiated the process of procuring these vessels and issued a Request for Proposal to Indian shipyards including Hindustan Shipyards Limited, ABG and Pipavav shipyards. Due to their faster speed and smaller size, midgets are able to escape the enemy Sound Navigation and Ranging (SONAR) probes making them useful in carrying out covert operations,and help troops to penetrate into hostile territory without getting noticed by enemies. In 2013 other noteworthy development, Vizag-based Hindustan Shipyards Ltd has bagged the contract for building four 500-tonne mini-submarines, which were designed back in the previous decade by Larsen & Toubro. The mini-submarines, to be delivered in the latter half of this decade, will be used exclusively by the Indian Navy’s MARCOS. The combat management systems have been designed and built by TATA Power SED, while Riva Calzoni will be supplying the periscopes and other masts that will host a SATCOM communications systems and LPI navigation radar. The sonar suite is likely to be supplied by ATLAS Elektronik.

The average MARCOS training drop-out rate is more than 90%. The force has its own training facility, first as an adjunct of the operational company at INS Abhimanyu, in Bombay, later as the Naval Special Warfare Tactical Training Centre. For combat diving training, the commandos are sent to the Naval Diving School, Kochi. There are plans to move the Naval Special Warfare Tactical Training Centre to the erstwhile Naval Academy facility in Goa where it will be set up with focus on jungle warfare as well as counter insurgency operations. The new facility will be modelled on the lines of CIJWS of the Indian Army in Mizoram.

3)Garud Commandos-

Garud trainees undergo a 72 week Basic Training course, which is the longest among all the Indian special forces but it also includes basic training. The total duration of training before a trainee can qualify as a fully operational Garud is around 3 years.

The initial phase is a three month probationary training which filters out the promising candidates for the next phases of training. This phase, which usually has a high attrition (Drop-out) rate is conducted at the Garud Regimental Training Centre located at Hindon, near New Delhi.

The subsequent phase of special operations training is imparted by the Special Group of the Special Frontier Force, the army, NSG and the paramilitary forces. Those who qualify, proceed to the Parachute Training School (PTS) at Agra to complete the basic airborne phase. Trainees are trained along with paratroopers of the Indian Army.

The remainder of the phases concentrates on niche fields like jungle and snow survival, demolition, etc. Garuds also train at the diving school of the Indian Navy and the Army's Counter Insurgency and Jungle Warfare School (CIJWS). The final phase of training is active operations on being attached to Special Force Units of the Indian Army, which helps the Garuds in gaining operational experience.

After induction, the commandos also undergo advanced training, including anti-hijack and counter insurgency training, jungle and snow survival techniques, specialized weapon handling and advanced driving skills.

After reading through this we must realize what a tough life the army men in general and especially these commandos lead! My respect went up by a hundred times for their professionalism and for keeping us safe. If you have any question related to it you may ask below ! .

How to make secure login and logout system using php and mysql ?

2015-01-03T02:36:00.000-08:00

Learn to create a simple login system with php + mysql script, this tutorial is easy to follow, teach you step by step.

Overview
In this tutorial, we create 3 php files for testing our code.
1. main_login.php
2. checklogin.php
3. login_success.php

Steps
1. Create table "members" in database "test".
2. Create file main_login.php.
3. Create file checklogin.php.
4. Create file login_success.php.
5. Create file logout.php

STEP1: Create table "members"

For testing this code, we need to create database "test" and create table "members".

CREATE TABLE `members` (
`id` int(4) NOT NULL auto_increment,
`username` varchar(65) NOT NULL default '',
`password` varchar(65) NOT NULL default '',
PRIMARY KEY (`id`)
) TYPE=MyISAM AUTO_INCREMENT=2 ;

--
-- Dumping data for table `members`
--
INSERT INTO `members` VALUES (1, 'john', '1234');

STEP2: Create file main_login.php

The first file we need to create is "main_login.php" which is a login form.

<table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">
<tr>
<form name="form1" method="post" action="checklogin.php">
<td>
<table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF">
<tr>
<td colspan="3"><strong>Member Login </strong></td>
</tr>
<tr>
<td width="78">Username</td>
<td width="6">:</td>
<td width="294"><input name="myusername" type="text" id="myusername"></td>
</tr>
<tr>
<td>Password</td>
<td>:</td>
<td><input name="mypassword" type="text" id="mypassword"></td>
</tr>
<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
<td><input type="submit" name="Submit" value="Login"></td>
</tr>
</table>
</td>
</form>
</tr>
</table>

STEP3: Create file checklogin.php

We have a login form in step 2, when a user submit their username and password, PHP code in checklogin.php will check that this user exist in our database or not.If user has the right username and password, then the code will register username and password in the session and redirect to "login_success.php". If username or password is wrong the system will show "Wrong Username or Password".

<?php

$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name="test"; // Database name
$tbl_name="members"; // Table name

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];

// To protect MySQL injection (http://us.php.net/mysql_real_escape_string">more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);

$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);

// Mysql_num_row is counting table row
$count=mysql_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1){

// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
?>

STEP4: Create file login_success.php

User can't view this page if the session is not registered.

// Check if session is not registered, redirect back to main page.
// Put this code in first line of web page.
<?php
session_start();
if(!session_is_registered(myusername)){
header("location:main_login.php");
}
?>

<html>
<body>
Login Successful
</body>
</html>

STEP5: Create file Logout.php

If you want to logout, create this file. The code in this file will destroy the session.

// Put this code in first line of web page.
<?php
session_start();
session_destroy();
?>

For PHP5 User - checklogin.php

<?php

ob_start();
$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name="test"; // Database name
$tbl_name="members"; // Table name

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

// Define $myusername and $mypassword
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);

$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);

// Mysql_num_row is counting table row
$count=mysql_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1){

// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}

ob_end_flush();
?>

Loading data while scrolling the page down using jquery ?

2015-01-03T02:29:00.004-08:00

This tutorial about my favorite placeDzone like data loading while page scrolling down with jQuery and PHP. We have lots of data but can not display all. This script helps you to display little data and make faster your website.

Database Table
CREATE TABLE messages(
mes_id INT PRIMARY KEY AUTO_INCREMENT,
msg TEXT);

Browser Capability : Safari, Firefox, IE, Chrome

load_data.php
When we are scrolling down a webpage, the script($(window).scroll) finds that you are at the bottom and calls the last_msg_funtion(). Take a look at $.post("") eg: $.post("load_data.php?action=get&last_msg_id=35")

<?php
include('config.php');
$last_msg_id=$_GET['last_msg_id'];
$action=$_GET['action'];

if($action <> "get")
{
?>

<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
function last_msg_funtion()
{
var ID=$(".message_box:last").attr("id");
$('div#last_msg_loader').html('<img src="bigLoader.gif">');
$.post("load_data.php?action=get&last_msg_id="+ID,

function(data){
if (data != "") {
$(".message_box:last").after(data);
}
$('div#last_msg_loader').empty();
});
};

$(window).scroll(function(){
if ($(window).scrollTop() == $(document).height() - $(window).height()){
last_msg_funtion();
}
});
});
</script>

</head>
<body>

<?php
include('load_first.php'); //Include load_first.php
?>

<div id="last_msg_loader"></div>
</body>
</html>

<?php
}

else
{
include('load_second.php'); //include load_second.php
}
?>

load_first.php
Contains PHP code to load 20 rows form the message table.

<?php
$sql=mysql_query("SELECT * FROM messages ORDER BY mes_id DESC LIMIT 20");
while($row=mysql_fetch_array($sql))
{
$msgID= $row['mes_id'];
$msg= $row['msg'];
?>
<div id="<?php echo $msgID; ?>" class="message_box" > 
<?php echo $msg; ?>

</div>

<?php
} 
?>

load_second.php
Contains PHP code to load 5 rows less than last_msg_id form the message table.

<?php
$last_msg_id=$_GET['last_msg_id'];
$sql=mysql_query("SELECT * FROM messages WHERE mes_id < '$last_msg_id' ORDER BY mes_id DESC LIMIT 5");
$last_msg_id="";
while($row=mysql_fetch_array($sql))
{
$msgID= $row['mes_id'];
$msg= $row['msg']; 
?>
<div id="<?php echo $msgID; ?>" class="message_box" > 
<?php echo $msg;
?>

</div>

<?php
} 
?>

CSS
body

{
font-family:'Georgia',Times New Roman, Times, serif;
font-size:18px;
}

.message_box

{
height:60px;
width:600px;
border:dashed 1px #48B1D9;
