Terms you often see in Ubuntu


Today's blog will be on Terms which we  often see while using Ubuntu but we usually ignore them as they are not of our use and doesn't bother us with anything.
Terms which will be discussed today will be:
  • purge
  • saucy
  • yannubuntu
  • IGN
  • HIT
  • GET
  • PPA
  • launchpad
  • i386
  • amd64
  • x86_64
  • Backports
Purge, purge is a package that is used to remove applications completely and removing all the instances of it. We can do that by using one of the following commmands:
    • > sudo apt-get purge
    • > sudo apt-get --purge remove
Whether they should or shouldn't both exist is perhaps a debating point.
However - they are absolutely identical. You can also check that by going through the man page of apt-get.

Saucy is basically Saucy Salamander who provides two images for ubuntu where one is the desktop version, the desktop image allows you to try Ubuntu without changing your computer at all, and at your option to install it permanently later.
Second is the server image, the server install image allows you to install Ubuntu permanently on a computer for use as a server.
IGN, HIT and GET are the terms which we often see while performing our favourite command i.e. >sudo apt-get update .
so what basically all these are:
IGN stands for Ignored, this seems to say you have an entry in sources and there is no need to update the link of it.
HIT says that what you have is the latest version of archive and you don't need to update it.
GET means that there is a newer version of the archive and the link is updated to it so that you can upgrade it.

PPA PPA stands for Personal Package Archive. These are the package archives that are created by open source communities and must be added only after getting through the checks and with that these are added to install additional applications and packages.

Launchpad is basically a software collaboration platform which provides many services like:
  • Bug Tracking
  • Code Hosting
  • Ubuntu Package building and hosting
  • Code reviews
  • Translations
  • Mailing Lists
  • Specification Tracking  
i386 refers to the 32-bit edition and amd64 (or x86_64) refers to the 64-bit edition for Intel and AMD processors.

Wikipedia's i386 entry:
The Intel 80386, also known as the i386, or just 386, was a 32-bit microprocessor introduced by Intel in 1985... This is termed x86, IA-32, or the i386-architecture, depending on context.
Wikipedia's x86_64 entry:
x86-64 is an extension of the x86 instruction set. It supports vastly larger virtual and physical address spaces than are possible on x86, thereby allowing programmers to conveniently work with much larger data sets... After launching the architecture under the "x86-64" name, AMD renamed it AMD64... x86-64 is still used by many in the industry as a vendor-neutral term, while others, notably Sun Microsystems (now Oracle Corporation) and Microsoft, use x64.
Even if you have an intel CPU, you should use AMD64 to install 64-bit on your computer (it uses the same instruction sets).
Backports
When Ubuntu releases a new version of its OS every 6 months, that release is largely frozen in time. While the software that is part of that release will get bug fixes and security patches, new major releases of software and the new features that come with them will not be available.
That’s where Ubuntu Backports comes in. Backports offers a way to selectively provide newer versions of software for older Ubuntu releases. Most commonly, the Backports team will provide new versions of standalone applications which can be safely updated without impacting the rest of the system.
So that's all regarding the Terms which you often see while using Ubuntu
Next Blog: I.D.K. ;-)
Till then,
Adios Lactores
Happy Blogging!!!

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. If you have faced this error then trust me, you have a really good hand in that Linux Based OS because you have worked enough to corrupt it once. Now making this post a little brief lets jump directly to the solution!! There are more then one solution for it and different in OS using different packaging system, if your system is using dpkg , thus implying you'll be using apt to keep everything in tandem. So here is a list of solutions you can try for Ubuntu and few Others: This is the most easy solution if you hate CLI, but is not recommended at all. Use Synaptic Package
