Why Do Hackers Prefer Linux OS Over Win, Mac, Or Other OS??

Basically, Linux operating system is used for the hacking purpose and for penetrating tests. It has many numbers of tools pre-installed in it which are useful for hacking. In other operating systems like Windows or Mac, there are no tools for which can be used for hacking. Hackers prefer Linux over Windows, Mac or any other operating systems because Linux is an open source and Linux is portable compared to other operating systems. Check out the list of reasons below.

1. Linux Is Open Source

The main reason Linux is preferred by Hackers over other operating systems is because it is an open source operating system. An open source operating system provides you the source code which you can manipulate for hacking. While other operating systems are not open source so you cannot change anything and make use of it for hacking. In Linux, you can redesign the whole operating system if you wish to.

2. Linux is more secure than other operating systems

Linux has always been more secure than any other operating system. Linux has tools and can perform activities which can help you stay anonymous. While other operating systems won’t let you stay anonymous like Linux does and at some point you will get caught. The majority of the hackers use Linux over any other operating system because you can practice hacking and penetrating tests without any trouble of getting caught.

Recently UNIX-based operating systems are getting raised in the market of technology after Android and Mac was developed based on UNIX. But at the same time, these platforms are not safe from hackers because they are open source and based on Unix.

3. Linux is universal.

Since most of the things are running based on “UNIX” these days like from routers to operating systems and web servers, Linux is everywhere. And since it is being used everywhere, hackers would love to prefer it over other operating systems because hacking a device from the same platform will be easy.

4. Linux is lighter and more portable
Linux is lighter and more portable compared to other operating systems.
You can boot a Linux operating system in less than the half time consumed by windows while installing it. Also, the tools consume a very little amount of memory compared to other operating systems.

These are few reasons why hackers prefer Linux over other operating systems.

पैसे की कमी से कॉलेज छोड़ने को हुआ मजबूर, 5 महीने में कमा लिए 6.5 करोड़

सफलता का कोई फॉर्मूला नहीं होता। यह साबित किया है इस लड़के ने जिसने पैसे की तंगी के चलते कॉलेज में दाखिला नहीं लिया और अपना बिजनेस शुरू करने की सोची। बिजनेस शुरू करने के बाद मात्र 5 महीने में ही उसने साढ़े छह करोड़ रुपए से ज्यादा की इनकम कर डाली।

लोन लेकर नहीं करना चाहता था पढ़ाई
एलेक्स ट्यू लोन लेकर कॉलेज की पढ़ाई नहीं करना चाहता था। उनका मानना था कि लोन लेकर पढ़ाई करने के बाद लोन चुकाने में सालों लग जाते हैं। इसलिए उसने पैसे कमाने का आइडिया सोचा और फिर उसने एक वेबसाइट लॉन्च की। जहां उसने एक डॉलर प्रति पिक्सल के रेट पर ऑनलाइन विज्ञापन बेचने का काम शुरू किया। ट्यू का यह आइडिया क्लिक कर गया और उसे इस बिजनेस में सफलता मिली।

कैसे शुरू हुई वेबसाइट

वेबसाइट पर कंपनी के विज्ञापन बेचने का आइडिया आने के बाद डोमेन का रजिस्ट्रेशन और होस्टिंग सेटअप करने में उसे 3500 रुपए (50 यूरो) का खर्च हुआ। उसे पूरा विश्वास था कि उसने जो बनाया है, उसमें लोगों की दिलचस्पी बढ़ेगी और इंटरनेट के युग में इस बिजनेस को आगे काफी फायदा होगा।

2 महीने में ही कमा लिए 3 करोड़

एंटरप्रेन्योर डॉट कॉम के मुताबिक, 26 अगस्त 2005 को द मिलियन डॉलर होमपेज नाम से वेबसाइट की शुरुआत हुई। लॉन्चिंग के बाद धीरे-धीरे वेबसाइट का प्रचार होने लगा। उसने एक दुकान भी खोल ली, जहां लोग आने लगे और विज्ञापन के बारे में पूछताछ करने लगे। एक महीने के बाद ही उसे साइट से 1.6 करोड़ रुपए (2.5 लाख डॉलर) की इनकम हुई। फिर उसके दो महीने बाद उसकी कमाई बढ़कर 3.2 करोड़ रुपए (5 लाख डॉलर) हो गई।

5 महीने में कमाए 6.5 करोड़

डिमांड बढ़ने के साथ साल 2006 में वेबसाइट पर सिर्फ 1000 पिक्सल की जगह खाली थी। इसलिए उसने बचे हुए स्लॉट को 24.40 लाख रुपए (38100 डॉलर) में ईबे पर नीलाम कर दिया। इस तरह उसने 5 महीने में कुल 6.5 करोड़ रुपए (10.371 करोड़ डॉलर) की कमाई कर डाली।

योग पर भी शुरू की वेबसाइट

पहली वेबसाइट की सफलता के बाद योग की बढ़ती लोकप्रियता को देखते हुए ट्यू ने Calm नाम से वेबसाइट शुरू की, जहां योग से जुड़ी अनेक जानकारी मौजूद है। ट्यू ने इस वेबसाइट से हुई कमाई को उजागर नहीं किया है, लेकिन उन्हें यहां से सालाना करोड़ों की कमाई हो रही है।

What is Bitcoin? How does BitCoin Work?

Nowadays, Bitcoin is trending. You may have also heard this term. In this article, I will explain what is Bitcoin and how does it work. I will try to solve most of the basic queries about bitcoin and cover everything you need to know about it.

What is BitCoin?

Bitcoin is a form of digital currency created in 2009. The person who created the bitcoin used the alias Satoshi Nakamoto but no information about the real identity is known. The idea behind the currency was to develop a currency system independent of any central authority. The currency is electronically transferable with instant transfer on very low transaction fees.

Nowadays, Bitcoin is trending. You may have also heard this term. In this article, I will explain what is Bitcoin and how does it work. I will try to solve most of the basic queries about bitcoin and ..
This digital form of currency operates under encryption and the transactions are computed with the process of mining.

Unlike other currencies in the world, this is a purely digital currency and there is no central bank that prints it. There is also no system to control Bitcoin. It uses peer-to-peer technology. Your payment is sent directly to another person. Bitcoin was designed to have a maximum number of coins. Only 21 million Bitcoins can be created the original specification.

How Does Bitcoin Work?

Bitcoin is virtual currency that needs no bank. Once you own a bitcoin, it is like owning a physical gold coin. Bitcoin transactions are managed by Bitcoin Blockchain. Since the Bitcoin was invented, Bitcoin blockchain has operated without significant disruption.
Blockchain holds the record of each Bitcoin as Block. Roughly every 10 minutes, a new “block” is added in this chain holding the all of the transaction that has taken place in the last 10 minutes. These records reflect the public address of Bitcoin.

The public address is a 27 to 34 character string of uppercase, lowercase letters and the digits from 0 to 9. When you want someone to send you a Bitcoin, you need to tell him the public address. Each of this public address has a corresponding private key. Whoever has this key has the ability to spend that coin. Private keys are 51 characters long in the same format as a public address.
You can use your Bitcoin to purchase goods and services online. To spend an amount of bitcoin, you must use your private key to cryptographically sign the transaction at the time of sending it to another address.

When one person sends some Bitcoins to any other person, this transaction is then broadcast to the network and it writes a transaction into the block chain. This transaction confirms that your address no longer owns the spent bitcoins and now the bitcoins are held at the receiving address.
The computers that write new blocks to blockchain are known as miners.

There is no chargeback

There is one important thing about Bitcoin you need to know. Once the Bitcoin have been sent, they are gone. You cannot retrieve them. But it will also reduce the banking frauds where people make a purchase and then contact the credit card company to make a chargeback.

A few years back, 1 Bitcoin was equal to 1 USD but now it is being traded for USD 1779. As the price depends on the demand and supply, it is expected to go up and will soon cross the value of USD 4000 in coming soon.

Why Are Bitcoins So Controversial?

Bitcoins are private and this is the reason we saw several controversies around Bitcoin in past. It offers a certain amount of anonymity. Since 2011, usage of Bitcoin has increased among criminal traders who are using it to hide their
black money from the eyes of law enforcement. They invested millions of dollars in this. This is the primary reason why the Bitcoin price has gone up in recent years.
