Keyboard shortcuts, like [Ctrl-C] were created at Xerox in the 1970s, and include functions like cut, copy, and paste.But the crown jewel of shortcuts, Control-Alt-Delete, was created in the early 1980s by David Bradley, an IBM engineer.It only took 5 minutes to dream up the iconic combination, which became a hit among IBM employees, then got programmed into the company’s original PC.

The First Keyboard Shortcut: Ctrl-Alt-Del

<ul><li>Make shortcuts easy to remember.</li><li>Ensure they make sense with existing keyboards.</li><li>Develop combinations that don’t trigger other shortcuts.</li></ul>They also need to factor in how frequently a shortcut will be used. Shortcuts that are used more often tend to include simpler key combinations (e.g., copy and paste), while those that are less frequently tend to include more keys (e.g., force-quitting an app).

What Do Engineers See When Making Keyboard Shortcuts

One of the biggest trends in productivity software is using shortcuts. Companies like Notion, Superhuman, and Figma have created their own shortcuts to help users save time by ditching the mouse.If you’re looking to start using your keyboard more effectively, Use The Keyboard is a website that lists shortcuts from a range of popular apps and websites.You can always take your keyboard into your own hands — both Mac OS and Windows allow users to create their own shortcuts.

Encoding is a way of translating between different formats. Like converting a Spanish recipe for cake into English.

Encoding

Encryption is a way of protecting data behind a secret. Like sealing a box of chocolate in a locked safe so your kids don’t find it.

Encryption

Hashing is a way of permanently converting from one recognizable thing to something uniform and simple. Like grinding a cow into a hamburger – you can always make a burger, but you can never put the cow back together again.

Hashing

Decoding the terms in cybersecurity in a human way.

Encryption, encoding, and hashing are three related but distinct concepts. It's important for you to understand all three.

Encoding, Encryption, and Hashing — Remembering the Difference

The question of whether a computer can think is no more interesting than the question of whether a submarine can swim.

Edsger W. Dijkstra — ‘The question of whether a computer can think is no more interesting than the question of whether a submarine can swim.’

Variables and Constants are mostly misunderstood in programming. Most of the time, most of the people read bad definitions on Constants. A thread on this.

Variables vs Constants

First of all, we need to understand the usage of both variables and constants. Variables are used to store values which can be changed in run time whereas constant cannot be changed. {1/9}

But some of the websites/people explain these two in the wrong way. Mostly the definition for constant would be "A constant is a variable that can't be changed in the program". {2/9}

It totally makes no sense. This statement states that a CONSTANT is a VARIABLE but it's value can't be changed. If CONSTANT is a VARIABLE then the value can be changed. A total collapse in the meaning. {3/9}

So, both "Variable" and "Constant" come under a concept called "Identifiers". As the name suggests, identifiers help us to identify a value which is stored in the memory with the help of a name. It's like a box which contains some values/information with a label attached. {4/9}

Say if you wanna store a number "42" in your program/code, you can assign it to an identifier. So that you can use it later in your program. {5/9}

If a value stored in an identifier which can be changed in the run time, it is called a "Variable". If it cannot be changed it is called a "Constant". {6/9}

Values stored in memory can't be accessed without knowing the address. Since we can't remember addresses, we need some kind of label which points to that address. Something like a contact number saved in the phone. We can’t remember phone numbers, but we can remember names. {8/9}

Also Also identifiers can be function names, type names, class names, labels, etc.,can be function names, type names, class names, labels, etc., {9/9}
