Category Image 101

An equipment company wishes to create a database to support the hiring of tools and machinery to clients. The company has three types of equipment: power tools, such as drills and vacuum cleaners, plants such as excavators and scaffolding. Each piece of equipment is identified by a number. Power tools are described by their model and the voltage they use, whereas plants are classified by their model and their size tonnes. can be traditional, aluminium fibreglass; in addition, its width can be single or double. A large piece of equipment may be composed of smaller pieces of equipment.

The company has various outlets and each has staff including a manager and several senior technicians who are responsible for supervising the work of allocated groups of technicians. A supervision record is also kept for a specific date. All employees are identified by their number, name, date of birth (DOB) and address. Furthermore, a record is kept on their employment records and their qualifications.

Each outlet has a stock of equipment that may be hired by clients for varying periods of time, from a minimum of four hours to a maximum of six months. Each hire agreement between a client and the company is uniquely identified by using a hire number. Each client is identified by a number and a name. The company insists that each client must take out insurance cover for each equipment hire period. Each insurance cover is identified by a unique insurance number and includes the description of the insurance. The company wishes to keep a record of the member of staff who was in charge of a specific hire agreement. Each piece of equipment is checked for faults when it is returned by the client, and the faults/defects/damage recorded. The company keeps a record of the hire history of each client.

  1. Create an ER diagram for the above scenario and indicate the cardinality of relationships and the nature of the associations (mandatory or optional). You should allocate adequate attributes to the entities of interest, especially the identifiers.

How To Scan a URL for Malicious Content and Threats in Java

At this point, we’ve all heard the horror stories about clicking on malicious links, and if we’re unlucky enough, perhaps we’ve been the subject of one of those stories.  

Here’s one we’ll probably all recognize: an unsuspecting employee receives an email from a seemingly trustworthy source, and this email claims there’s been an attempt to breach one of their most important online accounts. The employee, feeling an immediate sense of dread, clicks on this link instinctively, hoping to salvage the situation before management becomes aware. When they follow this link, they’re confronted with a login interface they’re accustomed to seeing – or so they believe. Entering their email and password is second nature: they input this information rapidly and click “enter” without much thought.

How To Get a User’s IP Address With PHP

Featured Imgs 03

In PHP, there are several methods to retrieve a user’s IP address. We will explore two of those ways in this article.

The most reliable way to get a user’s IP address in PHP is to use the $_SERVER superglobal variable.

The $_SERVER superglobal variable contains information about the server environment, including the user’s IP address. Here’s an example:

<?php
$ip = $_SERVER['REMOTE_ADDR'];
echo $ip;
?>

The $_SERVER['REMOTE_ADDR'] element returns the IP address of the client (i.e., the user’s device) that is making the request to the server. This method works well for most cases, but there are a few situations where it may not return the correct IP address, such as when the user is behind a proxy server or using a VPN.

To handle these cases, it is recommended to use the following code to get the user’s IP address:

<?php
function get_client_ip() {
    $ip = '';
    if (isset($_SERVER['HTTP_CLIENT_IP'])) {
        $ip = $_SERVER['HTTP_CLIENT_IP'];
    } elseif (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    } else {
        $ip = $_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}

$ip = get_client_ip();
echo $ip;
?>

In this code, we first check if the $_SERVER['HTTP_CLIENT_IP'] element is set. If it is, we use its value as the user’s IP address. If not, we then check if the $_SERVER['HTTP_X_FORWARDED_FOR'] element is set. If it is, we use its value as the user’s IP address. If neither of these elements is set, we use the $_SERVER['REMOTE_ADDR'] element as the user’s IP address.

This method provides a more robust solution for retrieving the user’s IP address, as it takes into account the possibility that the user may be behind a proxy server or using a VPN.

User Space Dynamic Tracing and Feedback Control

Featured Imgs 23

This article describes the use of a C library named Melon for user space dynamic tracing, processing the tracing data, and feeding back the results to the program itself and other remote programs.

When it comes to dynamic tracing, the first impression may be BPF, Dtrace, Systemtap, etc., but the dynamic tracing introduced in this article does not depend on these. The functions provided in Melon are more inclined to allow the program to complete its own dynamic tracing in the user space, without relying on the kernel, nor on Uprobe or USDT.
