Installing Ubuntu


Installing Ubuntu to your system can be harmful if you do not get through the basics first so recommended is that you first install Ubuntu in Virtual Machine to get passed through the basic errors first and install it on Dual Boot or as your single control Operating System.

Requirement:
  • A System passing the minimum requirements
    • Requirements vary from Environment to Environment.
      • Ubuntu Server CLI 
        • 300 MHz x86 processor
        • 192 MiB of system memory (RAM)
        • 1 GB of disk space
        • Graphics card and monitor capable of 640x480
        • CD Drive
      • Ubuntu Desktop Environment
        • 700 MHz processor
        • 512 MiB RAM
        • 5 GB of hard-drive space
        • VGA capable of 1024x768 screen resolution
  • Ubuntu Installation version ISO file
    • you can get the iso from this link
      • http://www.ubuntu.com/download
  • Any Installation Media
    • USB stick
    • CD/DVD
    • Floppy Drive 

Ubuntu installation in Virtual Machine can be done by you, here I'll tell you about the basic terminologies which you must know and must take care of while while installing Ubuntu.
After you have successfully booted into the device which has the image file(iso) of Ubuntu then you have to go through the basic steps like first of all
  • Click on Install Ubuntu
  • Selecting Language 
  • Region and Time Zone
  • Keyboard Layout
Few other things which you can take care of and then comes the partitioning.
If you want to install Ubuntu only then you just have to select the Total HDD as your partition and install Ubuntu but if you want to install to install it along any other OS then you have to first manually unallocate some HDD space which will be acquired by Ubuntu which you can do by using the previously installed OS and using Gparted in case of Ubuntu.
After keeping say 250 GiB unallocated for Ubuntu then you have to manually do the partitioning in which you'll see this !!!

 

 In which it'll be mentioned that you have 250GiB of free space with which you have to do the partitioning with.
Partitions you have to make are just 3 in number.
  1. Swap
    • Swap is a partition which acquires space from HDD and uses it when your RAM memory gets full.
    • This increases the processing speed of your system as giving more RAM memory to it.
  2. /
    • ' / ' is the root directory of Ubuntu which is the most important directory and contains everything within it.
    • / contains sub directories as usr, bin, etc, boot, dev and many other where each of them plays an important role as bin contains all the binaries to be processed at runtime and so on
  3. /home
    • ' /home ' is the home directory in which we have the users and their data.
    • Every user has its own directory within /home directory which contains users personal files and all.

There's a simple formula for calculating Swap partition size i.e.
If M < 2
 S = M *2
Else
 S = M + 2
M is RAM Memory
S is Swap Memory
 
So you can assign Swap memory accordingly and after deciding the size what you have to do is you Select free space and then click on ADD after that a dialogue box will pop up and in that do the following:

 
Change Use as option and select SWAP and select Size as calculated above.
After you are done with Swap then assign ' / ' as shown in the picture above and assign Size depending upon your work like if you want to manipulate the OS like by installing multiple kernels you can do that in /usr/src/ and other stuff like that then assign more space to ' / ' and if you want Ubuntu for regular use then assign ' /home ' more size as /home contains all your documents and all.

So after assigning the ' / ' , Swap & ' /home' you are all good to go just click on Install Now and wait for it to get installed.

A Brief about RDMA, RoCE v1 vs RoCE v2 vs iWARP

Hello folks, Today we'll see what RDMA is and how different kind of network solutions work over Ethernet. For those who are wondering what these words are, this is a post about Networking and an overview can be, how to increase your network speed without adding new servers or IB over your network, wherein IB stands for InfiniBand which is basically a networking communication standard majorly used in HPC  that features very high  throughput  and very low  latency , for what HPC is, refer to my previous blog. This is how a Mellanox IB cable looks like In order, not to use IB, increasing the speed for Ethernet-based solutions is a better and cost-effective solution in many cases which is implemented using RDMA, thus saving cost and technology shift overhead for every admin out there. So let's see what RDMA is, RDMA stands for Remote Direct Memory Access  is a  direct memory access  from the  memory  of one computer into that of another without involving either one'

Cryptocurrency & Blockchain

Today we have a look at what is a cryptocurrency, what blockchain is, how does it link to a cryptocurrency! So let's dive straight into cryptocurrency and see what it is! Very well defined at Wikipedia " A  cryptocurrency  is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.", but is it actually is in even simpler language "A cryptocurrency is a digital currency that is created and managed through the use of advanced encryption techniques." A few keywords that you might need to know when talking about cryptocurrency are as follows:  Wallet - a place to store your cryptocurrency credentials: namely your private key  Private key - a 256-bit number, expressed as a hexadecimal  Eg: 9873D79C6D87DC0FB6A5778633389F4453213303DA61F20BD67FC233AA3326  When people say that they have lost their cryptocurrency(say Bi

Repairing your Ubuntu or Linux Dist. manually

If you are a regular user of any Linux based operating System then it is for sure that you have faced the error of "Broken Packages". When you are installing something new to your OS, it says Package cannot be installed because Package A depends on Package B, but Package B cannot be installed because of broken packages and this issue might occur while updating your system using Software Updater.
