What are build tools ?

Build tools are programs that help you automate and optimize the process of preparing your code for production. They can:

Convert SCSS / Less styles into plain CSS

Minify and combine files (CSS, JS, etc.)

Transpile modern JavaScript so it works in older browsers

Add versioning (hashes) to files for cache busting

What Does Minification Do?

Before Manification:

body {
    /* Set body attributes */
    background-color: black;
    color: white;
}

After Manification:

body{background-color:#000;color:#fff}

Minification:

Removes extra spaces
Removes comments
Shortens color codes
Sometimes reorders or combines rules for efficiency

Advantages of Minifying

Smaller file sizes → browsers load pages faster
Better performance → especially on slow networks
SEO benefits → faster loading can improve rankings
Reduced server costs → less bandwidth usage for high traffic

JavaScript Transpiling

Modern JavaScript (e.g., ECMAScript 6) may not work on older browsers. Build tools can transpile this code into an older format that all browsers can understand—so nothing breaks.

Cache Busting

When browsers cache your CSS or JS, updates might not show right away. Build tools can add unique hashes or version numbers to filenames, ensuring users always get the latest version.

Example

style.css → style.94f0ab.css

What is Peer-to-Peer(P2P) Network?

Mashhood Ahmed — Sun, 06 Mar 2022 16:06:00 +0000

A Peer-to-Peer (P2P) network is a network in which no separate server or computer/node controls the network Rather, everyone has the same permissions and responsibilities. Each computer in this network is called a peer, and all these peers are connected with each other. Unlike client/server network, each peer in P2P network act sometimes as a client and sometimes as a server. This network is mostly used for file/resource sharing purposes.

Applications

Bitcoin
Content Delivery
File Sharing

Advantages

Does not need an expensive server because individual nodes are used to access the files
If one computer fails it will not disrupt any other part of the network
Much easier to set up than a client-server network

Disadvantages

Files and folders cannot be centrally backed up
it can slow down the performance because each computer might be accessed by others.

What is a blockchain?

Mashhood Ahmed — Sun, 27 Feb 2022 17:31:28 +0000

Understanding blockchain could be confusing. Let’s understand it through an analogy first.

You may have seen or have been to many weddings, everyone in a wedding is like a conscious blockchain. In a wedding, everyone writes in their mental register that a certain man got married to a certain woman now if anyone claims that this woman is my wife (or she is not married), then everyone (present at the wedding) will reject this claim.

Similarly,

If a member of a study group misrepresents a topic in front of other members, the rest of the members will reject it because the topic written in this member's mental register does not match the rest of the members.

That's how blockchain works in real.

I hope you've understood blockchain through an analogies, let's look into the actual definition of a blockchain.

Technical Definition

Blockchain is a peer to peer (a network with equal permission and responsibilities), decentralized (every node/computer makes their decision), distributed (a system where parts of a system exist in different physical locations) public ledger between various nodes/computers. It keeps a complete, durable and unchanging record of the transactions that take place. The transaction is timed that is, with the transaction, the time of its occurrence is also written in such environment where there is a lack of trust.
