It is regarded by developers as one of the most successful cross-platform JavaScript environments for building reliable and powerful REST APIs, mobile applications, and online applications.
Describe Node.js
Node.js is a standalone runtime environment, not just a library or framework. It is dependent on Chrome's V8, a JavaScript engine capable of NodeJs Web Development running application code independently of the operating system or type of browser. Node.js is regarded as a standalone application on any machine because of its independence.
Frameworks for web applications
Any Node.js web application will require the web application framework as one of its most crucial requirements. Although the HTTP module allows you to construct your own, it is strongly advised that you build on the shoulders of others who came before you and utilize their work. If you haven't already decided which is your favorite, there are SEO Expate Bangladesh Ltd several to chose from. Express has a higher developer share than all other frameworks combined, according to a report by Eran Hammer.

10. A Note On The Importance Of Making Simple Mistakes
JS Debugging
You have been working with JavaScript for a while now. You must have realized that making simple
mistakes (syntactical or logical) are sometimes inevitable. However, it gets frustrating to locate
these errors as because unlike languages such as java, compilation errors are never displayed.
Answer this simple question – If there is an error in your code what will happen? The answer to the
question is that nothing will happen. The code will not run and the error message will not be
displayed. This makes debugging very difficult while working with JavaScript.
However, we can easily debug our code by using some simple techniques listed below.
JavaScript Debuggers
Setting Breakpoint
Debugger Keyword

Let us look at all the above options
JS Debuggers
Debugging is searching for errors in code. Debugging can be a very tedious and at times difficult
task.
The good news is that most browsers now come with built–in debuggers. These debuggers may be
activated by the developer. Once it is activated, the debugger will report errors to the developer.
Consider the following code
<!DOCTYPE html>
Check if Java is Enabled
function showBrowserProp() { if (window.navigator.Enabled()){ window.document.write("Java Is
Enabled"); }else{ window.document.write("Java Is Not Enabled"); } }

12. Web Development : A Website
Jamison Williams
Mrs. Postell
English III

Web Development:
A Website in the Making
$1.1 trillion in sales in 2011 were web–influenced. On a daily basis, people will continue to need
websites for certain businesses or certain jobs so that means the web development market will
continue to make money. Web development is the process of designing and developing a website
from scratch or the ground up. It is the "back end" or "behind the scenes" of a website, such as
programming. Web developers create programs and applications for the Internet or the World Wide
Web and focus on how a website works and functions. They create custom codes to accommodate
the unique needs of the client or clients, developing everything from the ... Show more content on
Helpwriting.net ...
Next, is server–side scripting, which is the code that powers the website and makes the website
work and operate. It's the mechanics of the website. Some examples of server–side languages are
ASP.net, Java, PHP, and Python. Server–side scripting is the most important part of building a
website because it's the back end and it wouldn't be a website without it. The last part, which is
database technology, helps the website run smoothly. This helps manage the information stored in
the database (McKay).
When a specific business has a bigger web project than usual, they often split up the responsibilities.
For example, one developer would focus more on setting up the back end or behind the scenes of the
website, while another developer focuses more on the visual aspect of the website or the client side
scripting (Shiotsu). This would include the graphics that are going to be used on the webpage or the
style of the webpage. The reason why businesses split up the responsibilities among the workers is
to eliminate the amount of time that they have to work on the website. If one web developer was
developing a website on a larger scale, it would take a huge amount of time to complete it.
According to Shiotsu in her article Web Development 101: What is a Web Developer, The advantage
of building a website from the ground up is that you can create something original that fits your

Similarly, if the old block is 8 bytes and the new block is 4 bytes, then the contents of the new block
are identical to the first 4 bytes of the old block. These semantics match the the semantics of the
corresponding libc malloc, realloc, and free routines. Type man malloc to the shell for complete
documentation.
5 Heap Consistency Checker
Dynamic memory allocators are notoriously tricky beasts to program correctly and efficiently. They
are difficult to program correctly because they involve a lot of untyped pointer manipulation. You
will find it very helpful to write a heap checker that scans the heap and checks it for consistency.
Some examples of what a heap checker might check are: Is every block in the free list marked as
free? Are there any contiguous free blocks that somehow escaped coalescing? Is every free block
actually in the free list? Do the pointers in the free list point to valid free blocks? Do any allocated
blocks overlap? Do the pointers in a heap block point to valid heap addresses? Your heap checker
will consist of the function int mm check(void) in mm.c. It will check any invariants or consistency
conditions you consider prudent. It returns a nonzero value if and only if your heap is consistent.
You are not limited to the listed suggestions nor are you required to check all of them. You

Homework 1 CS55 – Fall 2015
Name: Mahesh Devalla
Student ID: F002BY3.
1. (a) A few security exposures in the grocery self–checkout systems are as follows: Firstly, some of
the consumers in the intention of cheating my not scan the items that they procure from the store and
skip the baggage section to get the items for free of cost. There is no mechanism to check whether
the items are scanned or not if the tag associated with is removed or tampered. This security
exposure can lead to the disastrous effects where there is no screening. Moreover I have a seen a few
checkout systems in the local retailers where there is no one screening at the self–checkout system,
In fact it was quite easy for a person who wants to get the item for free. One can use false weights
while scanning the bag just by placing only a little of amount what he/she has got from the store and
later fill up the bag with some more items of same kind. This is a major security exposure where the
system cannot check the scanned weight and the weight that is placed in the bag is equal or not.
Hence the person who wants to falsify the weights can easily cheat the system with this flaw in the
security.

environment have both flexibility and easy–of–use. Given that the average user of this project can
be considered to be relatively "technically savvy," it is reasonable to provide them with a detailed
level of configuration such that they are comfortable programming in the environment. The editor
should have variety of options for settings as simple as syntax highlighting colors or as complex as
text completion preferences. Second, the manner in which the user interacts with the interface needs
to be refined. Precedents in this space already exist, the iPython Notebook3 being the most popular.

contains malware samples reveals characteristics that might be hard to acquire through behavioral
investigation. The following tools are popular and free monitoring and code–analysis tools that
allow one to observe Windows–based malware behaves with its environment (Zeltser, 2015):
– Process Monitor with ProcDOT: is a file system and registry monitoring tool that offers a capable
approach to watch how local processes write, read, or delete registry files and entries. This tool
enable one to see "how malware attempts to imbed into the system upon infection (Zeltser, 2015)."
– Process Explorer and Process Hacker: are process monitoring tools that replace the implicit
Windows Task Manager, helping one observe malicious processes, "including local network ports
they may attempt to open (Zeltser, 2015)."
– Wireshark: is a popular network monitoring tool which observes lab network traffic for malicious

Six Steps to Start Learning Embedded Systems Programming
When it comes to improving your applications, embedded programming is a fantastic tool to use.
But just like with a lot of programming tools, learning it can be tricky – especially in knowing how
and where to start. To help you find the whole thing just slightly less daunting, here are some tips for
you to get started.
These are not, of course, the only way to go about learning embedded systems programming.
However, if you are new to the concept, these steps might make it easier to get started and help you
focus on the things that actually matter. Indeed, these six steps are designed to make learning
embedded systems more effective and faster. So, let's look at the steps.
Step #1: ... Show more content on Helpwriting.net ...
Before that, you do need to sort out your equipment. You will need physical equipment since
embedded systems programming is all about the physical world.
What are the things you need? You will need to purchase at least the following items to get started:
A microcontroller
Soldering iron
Digital multi–meter (DMM)
A hardware debugger or JTAG adapter
Logic analyser
Finding these items online won't be difficult or costly. To cut down the price of electronics, you
should check which retailers are available through the OZCodes.com.au website. The vouchers can
help you find all the starting tools without paying yourself sick.
You can find the items as individual components or in some instances, shop for them as a starting kit
for embedded systems programming. The key is to just compare reviews of the different tools and
shop around for prices.
Step #4: Choose the microcontroller
You then need to select the microcontroller you want to use in order to get your embedded systems
26. running. There are plenty of different options to go with. The one you choose should be something
suited for your skill level and budget. Here are a few ideas to keep in mind when selecting the
microcontroller:
STM discovery kit is a good option for those starting out. They are cheap and accessible in terms of
use.
ARM tend to be the most commonly used option for embedded programming

* There are numerous non–graphical applications that make use of event driven programs, an
example of this is a smoke alarm: when it sense smoke and the density of smoke reaches a certain
level, the alarm goes off. An event has taken place there; a smoke alarm is non–graphical application
but it's very useful for event driven programming. Text – Microsoft DOS: An ms Dos operating
system makes use of no graphical interface; it doesn't make use of wimp when it's interacting with
the user. The user uses/enters computer commands into the computer to give instructions such as
saving files, opening new documents other than using a mouse to do these actions. A keyboard is
used to enter these commands and "key down" events occur when this happens. Non–graphical
applications compared to graphical applications ten to be out of date/old and harder to understand.
Of course this is not true in some cases, but with programs such as Ms Dos it is harder to remember
all the command lines. But with graphical applications that have an interaction interface are simpler
to understand and function. Summary In this task I have described procedural programming and its
structure with examples. I've described also what IDE is and how it simplifies the development

Computer Crime Report – CM0431
Introduction
In this computer crime report, the following will be discussed about the computer crime of Botnets.
This report will explain the role of computer forensics has in detecting and deterring the use of
botnets, the hardware and software used in forensically investigating botnets, the legal context of
using botnets such as legislation related to offences caused by using botnets, and the ethical and
professional challenges faced by computer forensics practitioners in investigating botnets.
A botnet is defined ( http://www.pcmag.com/encyclopedia/term/38866/botnet, 2014) as a
compromised group of computers, generally in large groups, that are used to generate spam (such as
phishing emails in large quantities), spread viruses to infect new machines, and flood a network or
web server using an enormous amount of request repeatedly and cause it to fail, this is known as a
distributed denial of service attack (DDOS).
The infected computers are normally infected by a Trojan horse virus, once infected the virus
usually opens an Internet Relay Chat (IRC) channel, this channel will wait for commands from the
user in command of the botnet network. In the modern world, there is large, and growing, industry
of selling lists of infected computers to hackers and spammers.
Rik Ferguson (2010) stated the first use of botnets came about in 1999, and the malware that started
it all off was known as "Sub7", a Trojan virus and "Pretty Park", a computer worm.

35. Personal Narrative: Point The Bedroom
Nervously I glanced around the room after 15 minutes of brainstorming on my laptop; No one has
yet finished; What a relief both for me and our team. We have to triumph on this one as it leads to
more opportunities than ever before. We know that we are close to finding the solution; the perfect
algorithm to solve the problem we are given. At that point the room was full of competition, starting
from high school students like me to senior university students in a group of four who were racing to
crack the obstacle ahead of us. We must figure out where the erroneous section is from 1000 lines of
code using our own debugger. At first it seemed like an impossible task considering we were just
getting acquainted both with the concept and one other. ... Show more content on Helpwriting.net ...
We followed an unorthodox strategy; Instead of fragmenting the code to four pieces and work on it
individually like everyone else, I come up with a riskier but efficient plan. First I prepared a
BOT(automated software robot) that divides the code into tons of parts; then it checks the syntax
errors that occurred for each part which made it a lot more easier than dealing with it ourselves.
While creating the bot, we were uncertain nonetheless optimistic it would work. Having realized I
just took a huge risk, I hit ENTER and started waiting for the 'BOT' to initiate. It was one of those
moments you know it might not work but again you never know until you try. Fortunately it run; we
scanned the first 10 lines of code and found no error. Now it's a waiting game where we definitely
have the advantage. We shared the algorithm and executed it on all our computers so we can process
it 4 times faster. Just 2 minutes later, one of my teammate's laptop suddenly stopped running, it
simply outputted "line #147", I recall shouting, "we did it!" due to exhilaration. Impeccable as a

whether it is a software developer, website developer, etc, provides the ability to start from scratch
and build a fully functional program that is capable of performing actions that the developer wishes,
with the only limiting factor being the developers imagination. It is possible to get the code to
program for free, along with free programs, which can be used to create a website that can bring in
revenue. It is also rewarding to know users are on your website and benefiting from it. Programming
increases the knowledge that a developer has and this is likely to help with their confidence within
the area. Being able to program has high employability attraction so their knowledge can benefit
them and help them earn money. The CPU (central processing unit) in a computer system works by

39. Taking Ownership Of Learning Process
To me, taking ownership of learning means understanding that the only person who is capable of
getting me to learn something is me. Even in highly structured, lecture–oriented classes where the
pedagogue–to–student ratio is close to one, the onus of developing a deep and useful understanding
of the material is on the student. Fortunately this is something that I came to realize as a younger
man, whilst between attempts at my Bachelors, and I feel that it has served me quite well. On taking
ownership of the learning process by setting personal educational goals, and monitoring their own
progress: The reason I set out to learn something is because I wish to be able to apply it to solve a
particular problem. The reason I pursue a degree is because I wish to apply a specific set of skills
and knowledge to the solution of many related problems, or to develop the necessary understanding
to identify novel problems and then solve as much of those problems as is possible. My barometer
for success is whether or not I 've gained the requisite understanding to be able to solve problems
using my new knowledge. On being self–motivated to learn and understand; not only driven by
grades or external praise: This is my default psychological state, though it has definite drawbacks,

Defining buffer overflow
Buffer overflow vulnerability considered one of the most common security exploit to exist, focuses
on buffers, or memory allocations exploits eventually giving the attacker full control over a
compromised system. This takes place when a process or programme writes or attempts to write
data onto a static sized memory block than it was initially allocated.
By taking advantage of the buffer overflow attacker are always aiming to completely take control of
the whole system by elevating their privileges to the Admin rights. To successfully attain this they
identify a function pointer in memory that they them taking advantage of the buffer overflow

Upon the crashing of the server and the exploit is identified (EIP) the attacker then has at hand
where to inject the malicious code.

instruction interpretable by the computer's CPU. Will then be executed.
8. Ensured the client has netcat to listen to specified ports where our shellcode will connect back.
9. ATM this point the payload executed of choice is the reverse shell a backdoor process that runs on
the server side and as soon as its executed its connects to the client that, as soon as it is been
executed at the server side, it connects back to the client, providing an interactive command
interpreter, thus allowing us to execute commands to the server. In this instance the reverse shell
was favoured because it can easily bypass any possible Firewall filtering incoming traffic to ports
that are not being used by the server.
Remediation against buffer overflow:
Enable ARC(Automatic reference counting) – this is a compiler(programme that processes
statements writing in a programming language e.g. C,C++) attribute that enables it to automatically
manage the memory objects.[2]

The animals which were identified as a nuisance to agricultural crops were deer, raccoons and
groundhogs (MacGowan et al., n.d). In some states, feral hogs would be added to that list, as well as
coyotes (only in areas that grow melons). As noted by Sramek, (n.d.) "Coyotes are known for their
particular fondness of watermelons and cantaloupes and will readily seek them as a food source"
(Coyote diets, para. 3). We limited the project to whitetail deer, due to a readily available test field
located in an area populated by whitetail deer; and whitetail deer are ranked as one of the leading
animals causing crop damage (Belant, Seamans, & Tyson, 1998, January). Additionally, whitetails

acoustic devices had recently been employed to some effect. One study using bio acoustics showed
great promise (Hildreth et al., 2013). It used eight distress calls of deer (recorded during capture and
release events) then played back when a deer crossed into the feeding area. Although the device was
only tested for two week, the "deer–activated bioacoustics frightening device (DABAFD) ... was
nearly 100% effective at reducing the number of times deer entered protected sites and 100%

The factors affecting the choice of programming language
Every programming language is used for difference purposes, and every language has his pros and
cons. There are also factors that affect the choice of which programming language to use. Which
are:
Reliability
Having a reliable prrogram is highly importan in programin. If an amployee gets handed a task with
a strict deadline. It it ismportant that the employee uses a reliable program so it doesnt crash. It is
important to use a reliable programming software. The program or software must be highly secure
and should be updated to the latestet version, if the sytem is old it has a higher chance of crashing
and may cause other problems to the computer sytem such as slowing the speed of the compter
down or not respoding on time of comand. I would recommend ADA only because it is the best and
has all the reliable features.
Expandability
Expandibilaty is when you wish for more than one user to work on a solution at a time Some
programs have a high expandibialty which means they can easily be used with any type of sytem the
user has, through my research I realiesd PHP support computer clusters and also can work with a
huge number of files.
Organisational Policy

other fault seeded program we received and discover the problems we encountered on the testing
end.
Debugging Process
We started the debugging process by running the code (as a client would) to notice the errors from a
high level. This would help us narrow down specific areas of the code we will need to examine later.
Since the program was not overly complex and the functionality was familiar (we wrote the same
program) we used similar test cases to the ones we used in production of our own student roster
program. We manually tested the functionality of the program using the Visual Studios 2015
debugger. On top of the familiar test cases, we tried every possible combination of inputs/actions we
could think of (some of which may not have shown an explicit error) and noted all of the bugs we

The NetBeans IDE 's Java Editor helps us quickly complete and generate code through its "smart"
code completion feature.
The editor used in NetBeans Supports many programming languages like Java, C/C++, XML and
HTML, to PHP, Groovy, Javadoc, JavaScript and JSP this is due to the extensible future of editor.
Hence you can plug in support for many other programming languages.
NetBeans can be reverse engineered to java with the help of jvm machine.
Project Management can be maintained easily and efficiently with the help of NetBeans IDE.
NetBeans IDE provides different views of our data, from multiple project windows to helpful tools
for setting up our applications and managing them efficiently.
Another important feature of NetBeans is rapid user interface development. With the help of this
feature we can design graphical user interface (GUIs) for Java SE, HTML5, Java EE, PHP, C/C++

degree is two–fold: first, after years of self study and independent research and learning, the depth
and rigor provided by a graduate level academic program will significantly solidify the skills and
knowledge I have gained. Second, the in–depth knowledge that comes from a graduate level
program will prove invaluable in furthering my career. Both my current position, Mobile Security
Engineer at Nike, and any future security related positions stand to benefit from a graduate program.
My current full time employment in a security related position is what shapes my decision to enroll

Are you a young, first year IT student wondering what it takes to excel in the software development
industry? Or are you a software engineering veteran but somehow feel that you have reached a
"peak" in your skills...there is still room for improvement but don 't know how to go about it? Are
you somewhere in between?
I believe that all software developers yearn to improve on their coding skills and come up with
beautifully written and rock solid applications. To do this however, one needs to be passionate about
the work. What do I mean? Do you enjoy spending long hours (including weekends and very late
nights) in front of you computer screen writing code and getting thrilled by what you can come up
with? If you do, keep reading, if not, maybe software development is not for you...seriously! One

Cost–Benefit Analysis and Project Budget We are creating a Smartphone application for use as a
travel aid for the public and the profit will be donated to the partnership for children charity. The
total budget allocated for this project is £20,000. We have £10,000 from our own funds and we will
be using this fund for the promotion of the app with £10,000. The council has also provided us with
£10,000 subsidy. We have used our funds on Feasibility, User Requirement and Analysis, Design,

Design involves translating the identified requirements into a logical structure and consists of
"defining the hardware and software architecture, components, modules, interfaces, and data to
satisfy specified requirements It involves defining the hardware and software architecture,
specifying performance and security parameters, designing data storage containers and constraints,
choosing the IDE and programming language, and indicating strategies to deal with issues such as
exception handling, resource management and interface connectivity. System design helps in
specifying hardware and system requirements. The system design specification is a starting point for
the next phase of the model. Implementation consists of constructing the product according to the
design specification. It involves converting the new system design into operation. This may involve
implementing the software system and training the operating staff before the software system is
functional. This step is performed by a development team consisting of programmers, interface
designers and other specialists, using tools such as compilers, debuggers, interpreters and media
editors. In testing all the components are methodically verified to make sure it is error–free and
make sure the requirements are met. An independent quality assurance team defines "test cases" to

69. The Pros And Cons Of Computer Science
What is Computer Science? Is it about observing scientific experiments on a computer? Is it a type
of engineering for computers? Well to answers those thoughts, no. Computer Science is all about the
software side of computers. Coding is the key word. Running and creating programs is what
computer science is. To create software, one must know a programming language. So then the big
question is, for a computer programmer what coding language should they learn?
First off, the language C is known by many programmers as a lingua franca. A middle ground
language for coders. If coders know C, they know C++ and possibly C#. C#'s syntax is similar with
C/C++ but distinct differences separate them. Microsoft created C# as a competitor to Java, so think
of this as a fork in the road for C. As stated in Wendy Logan's (2008) article, "Is C dead?", she made
the point that C is the language for test engineers because of how convenient and effective it is. She
also disclosed that C can optimize code beneficially to the coder because of the language's greater
access to the hardware and operating system. This ability leads to fine tuning of the program size
and execution speed of the compiler. The article mentions how C has a well–known community, so
coders have greater access to code reuse tools. C has a specific purpose in the industry because of
Microsoft Visual Studio, it gave coders of the language a place to develop for.

The first function, as shown in Listing 2.1 creates a dialog for "gain1 parameter" which copies to C
variable "gain1". On the other hand, in the C source program, a global variable "gain1" of type float
or short should be declared and initialized. A slider or dialog appears when GEL function from
"Scripts"–menu is selected. With slider or dialog function, shown in Figure 2.3, we are al– lowed to

Executive Summary
Over the past few years the number of mobile devices owned per person has grown, and will
continue to grow, exponentially. With more and more people using a variety of different devices that
suit their usability and productivity needs, businesses are trying to figure out how to adapt and
remain competitive. The Bring Your Own Device, or BYOD, phenomenon has crept up on many
major business, and they are now finding out the hard way that security and integration procedures
cannot be overlooked. The solutions for this issue are still in their infancy, but the two most
prominent include Mobile Device Management (MDM) and Mobile Application Management
(MAM). Although these are considered Band–Aids for a larger issue, businesses, at this time, must
adopt one of these two methods in order to provide adequate security for existing and new business
information systems, while maintaining convenience and personalization for their employees.

An independent quality assurance team defines "test cases" to evaluate whether the product fully or
partially satisfies the requirements outlined in the first step. Three types of testing typically take
place: unit testing of individual code modules; system testing of the integrated product; and
acceptance testing, formally conducted by or on behalf of the customer. Defects, if found, are logged
and feedback provided to the implementation team to enable correction. This is also the stage at
which product documentation, such as a user manual, is prepared, reviewed and published.
5. Maintenance
This step occurs after installation, and involves making modifications to the system or an individual
component to alter attributes or improve performance. These modifications arise either due to
change requests initiated by the customer, or defects uncovered during live use of the system.
Actually, every change made to the product during the maintenance cycle is recorded and a new
product release which is called a "maintenance release" and exhibiting an updated revision number

84. The Topic For My Capstone Project Was To Gain Introductory
The topic for my capstone project was to gain introductory knowledge for penetration testing. I had
little knowledge on the subject itself, but I was interested in it enough to base this project around it.
What I knew before hand was very basic information and I would need to learn a lot more before I
could consider myself fully introduced to penetration testing. The goal of my capstone was to learn
how to safely practice penetration testing, set up a virtual machine penetration lab, learn why a lab
would need to be set up, and lastly to find out why penetration testing is important.
Penetration testing is when a company pays a specialist to try and break into their network and relay
back to them any vulnerabilities they may find. Now ... Show more content on Helpwriting.net ...
Using these labels and their definitions explains the purpose of penetration testing a bit better.
White–hats use the same methods and tools to break into networks as a black–hat would, but they
disclose the security issue with the network owner. In a sense, a white–hat imitates a malicious
attack but there would be no harm done to the network.
What are the vulnerabilities in which a penetration test would look for? Most penetration tests
would go through an information gathering state in which they look for as many different possible
vulnerable targets, and they may also capture the network traffic and investigate that as well. One
example of an attack could be infiltrating the file server and uploading a payload to that server. If an
attacker can find their way to accessing the file server, depending on what is kept on it, they could
also have access to secure files and any other sensitive information kept on it, possibly any of the
configuration files to that file server holding hashes for user passwords. Attackers may also look for
any vulnerable programs on network computers for more ways into the system. Depending on how
much effort a hacker wants to go through there is an endless amount of areas that they can check for
vulnerabilities. Anything from scanning port numbers to bypassing the firewall without being
detected, networks can be well secured but not to a point of being 100% safe from any
