what's Vim?     Vim is a highly configurable text editor for efficiently creating and changing any kind of text. It is included as "vi" with most UNIX systems and with Apple OS X                                                                                                            ---> From Vim.org  when i first heard it, what a command line editor which is awesome and i said to myself  NO WAY, there are tons of editor which looks good and easy learn curve such as Atom,Sublime,VSCode and bunch others What makes vim special than other editors?  Different from everything you have used before ( because it has modes - insert mode,visual mode,Command mode ) Forget the mouse ( why?...

To know about container importance,we need to know about virtual machine. Virtual Machine :         Virtual machine help us to run other operating system in host operating system. Uses of Virtual machine Malware Analysis - Without infecting the host machine we can able to analysis how the malware in virtual machine Huge software project require lot of dependency and lot of configuration. so they bundle everything in a container and transfer through virtual machine In serving different server ( hosting company ) Virtual lab - For learning what's wrong with virtual machine? Virtual machine is awesome but it take more resource which cannot afford by more people.   Not good as host machine when accessing hardware ( In Mac you cannot able to access wifi from virtual machine) Containers? Container provide operating system level virtualization there by we can able to run multiple isolated environment in same host system. It p...

This time not software,its hardware stuff What is a Network tap ?     A Network TAP (Terminal Access Point) denotes a system which monitors events on a local network and in order to aid administrators (or attackers) in analyzing the network.The tap itself is typically a dedicated hardware device, which provides a way to access the data flowing across a computer network. In many cases, it is desirable for a third party to monitor the traffic between two points in the network                                                                        --- From Wikipedia Application: Troubleshooting Network  IDS (Intrusion...

As the name says chain of block Now what is a block?       A block typically contains a  cryptographic hash of the previous block,  a timestamp transaction data    Where it is used?      It is the backbone of cryptocurrency i.e it ensure the security and integrity of data. The usage doesn't stop here well blockchain are resistant to modification of the data. so it can used in Bank Identity verification Hospital records and much more   How it ensures security and integrity of data? Block added to the chain, contain the hash ( result obtained from hash algorithm such as MD5,SHA) of the previous block so changes in one block lead to mismatch. Proof of work algorithm - Adding a node in the block chain require validation whether the new block is valid or not which is done my miner if they find the valid hash they will be rewarded How to do one?      The most interesting part ...

This time we are going to see how to use idle computing power to do something good or make profit 1. Volunteer computing :         It is an arrangement in which people ( volunteers ) provide computing resources to projects , which use the resources to do distributed computing and/or storage. Simply donating the idle computing power to someone,Sounds cool right  where it is used and what you can do with that ?      Scientist have many problems to deal with such as finding a New planet,analyzing outer space,finding cure for cancer or other disease. They need lot of computational power to do this kind of project. Many scientist cannot spent their Funds entirely in computational power. So                      BONIC - Berkeley Open Infrastructure for Network Computing BONIC is created to address this problem anyone with...

Well first what is a bot?      A bot is a piece of software that can execute commands, reply to messages, or perform routine tasks, as online searches, either automatically or with minimal human intervention Now how to create one?     Here i have created a bot that run in telegram and i will show you how to do Steps in creating a Telegram Bot   Create a account in telegram  Search for @botfather ( a bot that will assist you in creating new bot ) Inside BotFather chat type /newbot and it will ask name for the bot and username for the bot once you completed above things successfully then botfather gives you Token id which is essential to create a bot            In this image you can able to find the token id strike out by red color Well now we have everything we need , we can able to create a bot using python ( you can able to create in any language )  In command line ...

Facebook need no introduction, Every one heard about recent facebook data scandal and how worse it is. The one big question is " what are the info facebook know about me " Images you upload ( well it's just not image facebook also collect metadata of the image from facebook can tell image was taken in which phone,which time,which location )  These information are present in exif meta data.I will write a exclusive article in future     About our conversation i.e Messages in html files     Stickers that you used in your conversation     Videos , Audios and Gifs     Timeline Posts ( your status,birthday wishes,and you know the rest )     Based on your likes to the content, the ads are shown to you and what are the ads you clicked , what kind of ads you are interested( facebook make money from this )     Facial Recognition Data (Well facebook can identify you)  ...
