WiFi routers around us are mostly secured using a password. But do you know that your router has another protected (apparently) connection method? Yes, That's call WPS (Wi-Fi Protected Setup). WPS is a 8 digit pin that comes printed on your router specification label as well as on the router box. You can also find the WPS pin from the router admin panel. Now how does finding that help? Many times we need to setup our router or stuff like changing devices or passwords multiple times. In that case, forgetting the SSID and putting password again and again becomes a boring job. To save us from all that hassle, we can use WPS pin to stay connected with the router all the way till we finish setting our devices and set a password finally. But windows PC's only allows WPS button method. Now, we will learn about the way we can use WPS pin method to connect from windows platform. We'll need a software for that. It's named JumpStart .

Server! Sounds quite complicated and sophisticated, right? But do we know that any system that's capable of hosting some files could be called a file server? No? Let's see it ourselves today. We are going to create a file server through which files can be transferred across all the devices in a certain local area network. (If the appropriate ports are forwarded correctly, it can also work across wide area networks) This will definitely save us time and effort to transfer huge volume of data across systems without using long cables or pendrives every now and then. Let's download a small software named HFS from here  and open it. When opened for the first time, Windows firewall can ask for permission. Check all the boxes and click on Allow access. Now you'll see the interface of HFS like this. So as you can see, there's an address bar. It says 192.168.0.102:8080 Now if you try to put this address in any browser you'll see that your...

  What does these pictures look like to you? Pictures of a person from 2014-2017, right? No. Actually these pictures are fake. A new technology called Dueling Neuron Network, an advancement in Artificial Intelligence helped creating this. Dueling neural network is a system where two neuron networks contesting with each other like in a digital cat and mouse game. It is used to generate audible and visual data. The neural network has produced many pictures like the above ones. They look like real but they aren’t. GAN (Generative Adversarial Network) created these fake pictures. This particular network system replicates real data to produce fake data. Between two pictures above, left one is generator network which has the task to create training data and to get as realistic as it can. On the other hand, the right one is discriminator network which has the task to identify which one is real and which one is fake.  GAN is created through  pairing these two ...

I’m Md. Asifuzzaman. I’ve passed HSC from Birshreshta Munshi Abdur Rouf Rifles College. Later I got myself admitted at Bangladesh University of Professionals for doing my Bachelor of Science (BSc.) in Information and Communication Engineering (ICE). In my childhood days most of my leisure time used to get spent reading computer and mobile magazines and learning about latest technology because back then Internet wasn’t available that much. Also there was a speed limitation with a very high cost of bandwidth. Then I learned computer hardware assembly from online tutorial and by disassembling my own computer. I started learning JavaScript when I was in class 8. But I couldn’t gather a strong interest for programming languages. Networking, TCP/IP, Cyber Security, System Administration, Networking Administration, Virtualization, Database Management, Cloud Computing, Amazon Web Services etc. excites me these days. As part of that I started learning and working with these technologies. Wit...
