Littlehelp Upgradation

This is not a classic time oriented project post. There was a lot going on with family reasons, then the Midsems, and what not. Also most of my time (at least the time I didn't waste) went to developing Littlehelp.

Littlehelp in it's current form (http://littlehelp.epizy.com) is just a pile of unorganized code jumbled together (as students of 1st year could have managed), and hosted on a platform that regularly suspends the website because of over usage of resources (Thanks to the huge load of traffic near Midsem and endsem). Also, it was written in PHP, so we didn't hade that dynamic nature of the website we so wanted.

So since the past month, Me and my friend have been working to migrate the website to Heroku, and change the backent to NodeJS. This has been a cumbersome task, not only coding it from scratch, but also migrating the material from the previous website. Still, the work is pretty much complete, and I think the website will be live before the end semester exams. (New link: https://littlehelp.herokuapp.com)

Also, if anyone ever want to contribute anything technically, or give suggestions, they are free to do so on the github page. We went open source because we think it would provide the kickstart to new developers to contribute to open source projects.

WebGL - Perspective

04:18 PM Yesterday, We created a 3D 'F', that we can rotate, scale and translate. But somewhat was amiss. The 'F' we created was 3D, but it did not have the perspective. All the sides of the F were of the same size, ndependent of how far it was. This representation of 3D is called as Orthographic.  But it is not how we percieve real world objects. In real world, we assume there is an eye at the center of the screen, and we percieve closer objects as larger and far off objects as smaller. This type of representation is called Perspective. Today, I implemented this 3D perspective projection into yesterday's code. Following is how it looks now, the controls are similar, (with added [ and ] keys for z translation ).

WebGL - Orthographic 3D

11:40 AM Yesterday, we have dived into the visual world of WebGL, and completed the initial setup, and drew a simple 2D "F" figure. Today, I tried creating some 3D magic using WebGL. It was quite similar to 2D. Just needed to add another dimension to the translation and scale matrix.  Rotation was a different thing. Since in 2D, we can have rotation about only one, namely Z-axis. But in 3D, rotations about 3 different axes are possible. Hence we need to create 3 different methods for rotation about X, Y and Z axes. WebGL draws shapes using primitive triangles. We provide it with vertexes of triangles, and it draws them. For example, if we want to draw a rectangle, we would provide it with 2 sets of 3 vertex. One set of 3 vertex draws one triangle, and another draws another. If we provide the vertex such that the triangles have a common hypotenous, we get a rectangle. For the 3D F, I needed 16 rectangles. Hence I needed to supply 16 * 6, 96 vertices. Following ...

Cursor and Serial Ports

One might think that today was a weekend day, so I might have been able to progress much today. But there is always a roadblock, this one was named college. Taking a formality-only viva, but keeping the students busy without any work, and making them write a 14 page hand written assignment, which will never ever be opened, is some form of punishments college provide. So, enough about the day, what did I do today. Today was as uneventful as yesterday, but atleast I was able to progress a little more today, ( albeit at snail's pace ).  Today, I learned about how via assembly 'out' instruction, we can send data on Serial ports of our computer. Here we are actually writing a near machine level code to directly interact with hardware. How cool is that! So, improving the framebuffer printing I had created in the last post, today I used the Serial ports to send the command to serial port that is concerned with the position of "the blinking cursor" in the framebuffer. We ...
