Few Jokes on Unix Operating System and its functionalities *

I remember i wrote a joke on UNIX users a few years back in one of the blog. I was also sharing this with my colleagues in different offices i worked in. Few friends back there in Adobe system and Symantec used to love these kind of jokes. So i thought few more jokes that i have invented (or discovered or written ☺) since then.

The first one is:

Question - Why did the man using UNIX spend all day at the terminal?

Answer - Because he couldn't figure out how to use the "vi" command to exit!

This was a joke because of similar sound of bye and vi especially in some parts of the world.

Question - Why did the man using UNIX always wear sunglasses?

Answer - Because he was always 'ls'-ing in the sun!

Now this used the similarity between the word 'lying' and 'lsing'

Question - Why did the UNIX user wear a tie to the beach?

Answer - Because he wanted to be "root" in the office and "user" at the beach.

Question  - Why did the UNIX user put his computer in the freezer?

Answer - Because he wanted to "cool down" his "system".

Question  - Why did the UNIX user stare at the black screen for hours?

Answer - Because he was trying to "cat" the manual!

Please note that these are just jokes and should not be taken seriously. Unix users are just like any other group of people and should not be stereotyped or discriminated against based on their profession or preferences.

PS: The first of my such joke appeared here in 2013 - https://www.w3lc.com/2013/05/checking-file-system-directory-size-in.html

Cool Trick with website images!!!

Mathematics in itself is a fun and sheer joy if you are able to see through its beauty.

I feel that as you keep on realizing the application of mathematics and its ideas in different branches of science, philosophy and technology, you will start enjoying every aspects of it. Especially, I find the number science and the effects of simple functions on the ranges that a domain of inputs can bring as amazing. 

Let me show a simple trick using Javascript. It will use a great mathematical trick. Please feel free to dive into it if you want.

Remember that JavaScript is a popular scripting language. It powers the most popular Web 2.0 applications with a combination of web development technique called AJAX.
However, Javascript can and is very well employed to create stunning effects in Web pages.

In addition it can also be copied and pasted in the address bar of a web browser. This will run the javascript code in the address bar over the webpage/document already loaded in the browser.

Lets stop gambling with words. Some men (women too!) really need action. So, here it goes...

Steps:
1. Open a web page with some pictures/images
You may even try with this webpage itself (so no need to open new)
or, You may also open http://images.google.com and search for whatever you like eg. cartoon.
2. Copy and paste the following code in the address bar of your internet browser.

############################################
javascript:R=0; it_discussions=5;x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.images; DIL=DI.length; function mohdajf(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.mkssddddddddddd=Math.sin(R*x1+i*x2+x3)*x4+x5; DIS.top=Math.cos(R*y1+i*y2+y3)*y4+y5}R++}setInterval('mohdajf()',it_discussions); void(0);
#############################################

Voila!! The pictures have started dancing!
This is a single manifest of the power of Mathematics used with Javascript!

It is evident that there can be much of fun with this one line of code.

In case, you modify the code to create yet another stunning cool image motions, please share it on IT-Discussions Blog.
