Why Use Knowledge Base Software?
Give your customers the ability to answer frequently asked questions, access how-to videos, or download forms, while at the same time increasing your business efficiency and decreasing employee costs. How? Easy, use knowledge base software. A well-designed knowledge base management system can act as a self-serve information resource for both customers and employees.
What is a knowledge base system?
Basically, a knowledge base management system is a place for storing information that can be organized, searched, shared, and used for multiple purposes.
For example, let's say your new online business is inundated with customer queries and support requests. In addition, your support teams often need to scramble to find the most up-to-date information and resources to solve the customer's problem.
Using knowledge base software, you can build an effective online resource allowing customers to access the information they need whenever they need it, therefore reducing the number of support calls. A constantly updated system would also allow all employees instant access to the same knowledge, eliminating the frustration of searching multiple places for information that may or may not be current.
How can knowledge base software decrease costs?
Allowing the customer 24/7 access to information and instructional videos is less costly for your business than finding, training, and paying employees to staff the phones 24 hours a day. It can also help reduce the learning curve for new employees by storing the information they need in a searchable database.
Add instructional videos and both the customer and new employee can quickly learn the benefits of your product or service, how to assemble a product, ways to return merchandise, or what other products or services might complement the selected item. This reduces employee time answering queries and reduces training costs as customer service representatives can educate themselves on a number of procedures.
What information should a knowledge base system contain?
A knowledge base system should contain as much relevant information as possible to be useful for the people accessing the system. Remember, the knowledge base system is intended to act as a resource for the reader, so defining who the reader might be is crucial. The language you use and the information you provide may differ depending on whether you are addressing a customer or a sales representative.
Consider organizing the information into different levels of complexity for certain topics. For example, your customers will likely be interested in the "how to" of a topic, while a support technician will also need to know the "why." Business or technology jargon may be appropriate for a technical representative, but not for the layman trying to find the answer to a basic question.
Don't forget to ask for feedback!
A knowledge base system can allow customers to rate your knowledge articles and leave comments. This means that the business can stay on top of what information consumers need. Encouraging feedback also makes the customer feel vested in your business, an important way to promote loyalty and increase customer satisfaction.
Finally
Just keep two things in mind when designing your knowledge base system: know your reader and make every key word searchable. Customers that can find answers to their questions quickly are going to be left with a favorable impression of your business. And that translates to an increase in customer loyalty and retention.

How To Protect C# Applications From Buffer Overflow Attacks
This works through the utilization of user input. If the information size isn't checked properly before process the information in sure ways in which, it will become prone to a buffer overflow attack.
Protecting from buffer overflow :
we will be using the c-sharp console application(CLI) as an example.
First create a byte array which we will use to store the user input in next, notice that we are giving it a fixed size of 255 bytes.
byte[] byt = new byte[255];
Now we will get some user input.
Console.Readline()
Now let's convert it to a byte array.
Encoding.Default.GetBytes(Console.ReadLine())
Now set it to our previously declared 'bytes' byte array with a fixed size of 255 bytes...
byt = Encoding.Default.GetBytes(Console.ReadLine());
The vulnerability here is that the user can be inputting a string of 256+ bytes or characters so once converted to bytes, it'll be rather more than the 'bytes'; byte array will handle - a most of 255.
To fix this, we are able to merely check the byte count 1st before setting it to the 'bytes' byte array...
string readLine = Console.ReadLine();
if (Encoding.Default.GetBytes(readLine).Length <= 255) {
byt = Encoding.Default.GetBytes(readLine);
}
Now, if the user enters a string that once regenerate to byte is larger than the 'bytes' byte array will handle, it merely will not arrange to set the 'bytes' byte array to the new input.

· Remarks: The software also helps to improve the efficiency of the employee. Employers can generate a separate column to put down remarks through which employee need to work on in order to improve their performance. This certainly helps in working hard on required points and stay focused on the work. While evaluation, it is advisable to give examples of strengths and weaknesses of the employees this will help on working on the same in a better way.
· Seeking Feedback: The software also comes with feedback section that will help the employee to give feedback and approach the authorities regarding the assessment. They can also raise question regarding the same.
The main aim of having performance appraisal software is to get connected with employee through evaluating them and helping to keep their performance well for long term. Using of such software will certainly boost the working environment of the staff and take the company to the forward level.
Common Misconceptions Regarding Flipping Classrooms
Flipped classrooms are a great way of expanding the learning curve of students. Using this technique, students get to spend more time critically analyzing topics. Frequent discussions regarding topics in class help students learn more effectively. Moreover, students actually get to clear their confusions with the teacher in class. The idea behind flipped classrooms is to enhance interaction with students.
It focuses on clearing students’ concept regarding different subjects. Students also learn to become independent as they get used to learning about the topic at home. There are many misconceptions regarding flipped classrooms. These misconceptions are a reason why flipped classrooms are discouraged in general.
These misconceptions need to be cleared to enable a better understanding of flipped classrooms. Let’s look at some of the most common misconceptions regarding flipped classrooms:
1. Flipped Classrooms Are Based On Video Lectures
This is one of the most common misconceptions regarding flipped classrooms. This misconception arose because most flipped classrooms use media presentations. The only reason video lectures and media presentation are used is because students find it easier to learn this way. However, flipping classrooms doesn’t necessarily mean that students have to watch video lectures. A classroom can be flipped by asking students to read a particular topic at home or research on a particular topic of a subject. The aim of a flipped classroom is to encourage the students to study at home and discuss what they have learned in class.
2. Flipped Classrooms Eliminate the Need for Teachers
Flipped classrooms are not an alternative to teachers. Students may study at home using interactive means or books. But they need a teacher to provide guidance to them in class. This is one of the reasons why flipped classrooms have excellent turnarounds. Teachers can spend more time on actually coaching students about the aspects they don’t understand. The learning and lecturing part is received by the students at home.
3. Students Get Disorganized In Flipped Classrooms
Flipped classrooms are thought to make students disorganized. This is because when they are studying at home they have no supervision at all. However, the result of a flipped classroom is quite contrary to this. Flipped classrooms do anything but make students disorganized. In fact students, learn to become more independent. They learn to grasp the concept for various courses on their own. Moreover, if they have any confusion about a topic, the teacher is always there to guide them in class. Students get a sense of responsibility when using flipped classrooms.
4. Students Will Have No Peer Support
Since students do most of the studying at home, it is believed that they won’t have any peer support. On the other hand, there are other students during discussions in class. However, the main concern is peer support at home while studying. But this problem is solved with the help of online forums. Many institutes that have adapted flipped classrooms have online forums where the students can interact. These forums allow the students to post their queries there. The forum is monitored by the teacher who answers any questions the students may have. Moreover, the teacher can also make a note of the common queries and prepare a class discussion accordingly. In addition, these forums enable students to interact with each other to discuss problems they may have.
5. All the Subjects Will Need to Be Flipped
This is one of the major reasons why teachers avoid flipping classrooms. They believe that they alone cannot flip their subject unless the other teachers are doing so as well. However, this is not the case. In fact flipping a classroom can be done with just a single topic as well. The aim is to have the students prepare for the lesson at home and discuss the topic in class.
Now that these misconceptions are cleared, you will know how beneficial flipped classrooms are.

How to Turn a Static Website Into a WordPress Theme?
Still a number of business owners are running a static HTML website. But when it comes to making changes in the static site, it becomes mandatory for the website owner to have HTML programming knowledge. So, if you lack coding skills you must migrate your static site to a dynamic platform. WordPress is a highly popular dynamic platform and its popularity is not going to abate too soon. You don't have to throw all your HTML and CSS files away when moving to WP platform. Rather you can convert your HTML files to WordPress.
When converting HTML files to Wordpress theme, generally WP default theme named TwentyThirteen is being used. To carry out the conversion you'll need a copy of HTML as well as CSS files for your current site, which will be later converted to WP theme format. There are various choices you get in terms of the program, which is used to make edits in your file. Well, you can choose text-editors such as Notepad and Notepad++ or rather use Dreamweaver instead. For this purpose, you can take up HTML to Wordpress Service.
Here's a step-by-step procedure following which you'll be able to Convert HTML to Wordpress Theme.
Step 1: Creation of Files and Folders
Begin with creating a new folder on your system’s desktop. Next, give a name to the folder. Choosing an easy to remember name won't let you forget where the folder is saved, such as the name of your WPTheme. Once you've named your folder create two files namely style.css and index.php, and add both these files to the newly built folder.
In order to make your WordPress platform recognize the files you've just created, make sure to create a comment block for the style.css file including the information like theme name, URI, a brief description, version, author and author URI.
Later, verify whether the TwentyThirteen theme is set to be your active WP theme or not. Subsequently, in the WP admin panel go to Appearance and then the Editor. Open your style.css file and copy the content from it, and paste it into the newly built style.css file.
Step 2: Create new PHP files
To Convert HTML to Wordpress Theme in the second step you'll need to open WP theme editor, wherein your existing theme will be segregated into different parts – the header, footer, sidebar and main index. You can make use of the same components for building some other WP themed site. For doing so, you'll need to divide the components into different PHP files. Next, all you need to do is to copy of the code of each HTML section and place them in their respective PHP files.
Get logged in your WP admin panel. Open the theme editor followed by the file in which you want to copy the code. For instance, open header.php file of your static website; copy the code and then paste it into the newly crafted header.php file. Follow the same procedure for rest of the files.
Step 3: Use Newly Created PHP files to fetch data
To bring in data from newly crafted PHP files, open the index.php file in your WP theme folder saved on your desktop. Add PHP code to your file top and just after the tag, as show below:
Now you have constructed your own WP theme. But wait! Your theme is developed, but you may find it to be blank. You'll have to add content to it.
Step 4: Add your content
Now you may have to add content in your theme. How will you display the content in your tailor-made WP theme? For this purpose, you require WordPress’ loop function – The Loop.
Installing the loop function, requires copying the following code into your index.php template.
Step 5: Initiate your Theme
To set-up your theme, visit a FTP client and sign in to your website directory.
Go to wp-content>>themes folder.
Upload your new theme folder to this folder. Open your WordPress admin panel, go to Appearance>>themes tab. Your theme will now be visible just click on Activate.
That's it, you are done!
