10 Weird Things Only Programmers Will Understand

Yeah, you heard it right!

There is a saying that, 

“People sleep when they are depressed and try to forget their pain.” 

But for programmers, when they sleep after having frustration with their bugs or code error that they couldn’t solve and have no idea why they occurred in the first place, they somehow manage to find the error after waking up.

Probably some eternal angel comes to their sleep and tells them what’s wrong, and they somehow can solve the problem after that life-saving nap.

This happened to me tons of times, and so I believe it's worth sharing!

Once upon a time, a 10th-grade kid asked me, why are programmers using maths in their coding? is it that much important to learn maths to be a programmer?

She was talking about, 

• '='
• '=='
• '==='
• '!='

I love that, how innocent thought she got! I explain to her the things and their meaning of them.

= A single equal mark is used to assign a value to a variable.

== Used to check whether two expressions give the same value.

=== Returns true if both operands are of the same type and contain the same value.

!= The use of not equal; comes from the maths symbol ≠.

Suppose you have to count ten oranges. You will obviously count from 1, but programmers often mistake counting and start from 0. Just because they need to use that method in programming, it somehow becomes a habit for some.

If copy - paste option did not exist in the technology world, I don’t know what thousands of programmers would have done in their careers. It does not mean their work is just copy-pasting, but the value of these copy-paste keys (CTRL+C for copying and CTRL+V for pasting) and of Github, StackOverflow, Beingcoders, and other coding forums— you will never understand if you are not a programmer.

It’s just a basic logic method to work in the operating system. I will not go into details, but let me explain you.

A parent process creates a child process using a fork() system call. A parent process may have multiple child processes, but a child process has only one parent process.

So you see, it’s not about human beings. But parent kills their children if the assigned task is not needed anymore. That’s how an operating system works.

If you are not a programmer, you would never know that there is a tree in which the root is not under but at the top of the tree as weird it sounds, it exists in the programming field.

In short, tree graphs are drawn top-bottom because we write in that direction. Early days, when writing articles and calculations by hand, it was preferred to do drawings and graphs top-down, not worrying how much area they might take.

Otherwise, they collapse with lines above them, especially graphs that were means of calculation and partially unpredictable in length.

So yes, the root is at the top of the tree.

Ctrl + Y and Ctrl + Z make programmers feel safe.

Antivirus in windows sure is good. But when you write code and mistakenly delete the last line or some more lines, that’s when comes the lifesaver Ctrl+Y and Ctrl +z or in mac (command+Y) and (command +Z). 

In your childhood, you may heard about formatting your PC, and you pre-assume that, it will erase your all data, files and important work from your PC! But that's not true!

Let me put some light on this topic for you!

You can spend hours going through your hard drive and deleting all the files and documents you want, but using the delete key on your keyboard in Windows will only remove the shortcuts to the files making them invisible to users.

Deleted files still reside on the hard drive, and a quick Google search will show many options for system recovery software that will allow anyone to reinstate that data.

Formatting a disk does not erase the data on the disk, only the address tables. A computer specialist would be able to recover most or all the data that was on the disk before the reformat.

Bad for crime movies, where all information gets destroyed by breaking or deleting the hard drive. Right?

• Mbps stands for Megabits per second. 
• MBps stands for Megabytes per second.

1 megabit denotes 1,000,000 bits, and 1 megabyte denotes 1,000,000 bytes.

Mbps is used to specify Internet connection speeds, whereas MBps is used to specify how much of a file is downloaded/uploaded per second.

So next time, don’t get confused.

Last but not least, if you are not a programmer, you might rarely use semicolons and would never understand what a semicolon means to a programmer.

Most nights, they get nightmares at night just because they missed some semicolon at night and couldn’t figure it out, which eventually gets solved in the morning but again, for another missing semicolon, the nightmare pass through the next night.

Yeah, that’s the power of semicolons. You might wonder that if a semicolon is that important, why would anyone miss that? Well, when you have written thousands of lines of code, how are you going to notice that one tiny semicolon is missing in that huge ocean?
