Different Package system used in linux


Worried Of Dependency Hell in Linux?
To install a package, we need to run some commands or software center(like Ubuntu software center) and system should be connected to Internet (online) and each package has dependencies which must be satisfied to run the software properly .The offline installation of package in Linux is not easy .We cannot assure that everyone using computer is connected to Internet. It changes from person to person. To eradicate this, Microsoft windows uses .EXE files, simply double clicking it and with few clicks the software is installed and we can work with it. In Linux, it is just a dream but now the dreams come true .Yes now you can download a single package and install it offline system

FlatPak:
The package manager formerly known as xdg-app aims to provide cross platform sandboxed packages to every Linux distribution.
Advantage :
• Built with security i.e. programs are isolated from each other (sandbox).
• Support for different distribution.


Snappy: 
It’s a transactional package manager originally designed and built by Canonical Ltd. A single snap can work across range of Linux environments, making snaps a universal Linux package.
Advantage :
• Deployed in Internet of Things environment.
• In Ubuntu touch devices.
• No dependency.

ORB :(My Favourite)
The other project which provide portable version of package are ORB (Open Runnable Bundle) which can be downloaded from their website and can be used from pen drives, SD card. The ORB also provides Superdeb which can be used to install software offline
Advantage :
• Fast
• Portable
• Secure

Website:
• Snapcraft.io
• Orbital-apps.com
• Flatpak.org

Docker

Docker is used to run software packages called "containers". Containers are isolated from each other and bundle their own tools, libraries and configuration files; they can communicate with each other through well-defined channels                                                                                                --Wikipedia  I have already written a article about the containers you can check out in here https://thangaayyanar.blogspot.com/2018/06/containers.html This time, let's learn more about docker engine how we can use this. The important things we need to know in docker are Docker Image:  The container can be created with the help of Image. The Image file consists of code, libraries, environment variable...

BlockChain

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 ...

My experience in iOS Hackathon

This is my second hackathon, my first hackathon was on machine learning if you want to check out that article by following the below link https://thangaayyanar.blogspot.com/2018/02/what-i-learned-from-machine-learning.html So let's get started First let us discuss about the idea of what we are trying to achieve in this hackathon. From the above image you can able to know that we are going to recognize text from the image and use it to do find which field it is.  we separated this idea into three modules Identify the region Recognize the text  Field classification Module I : Identify the region To identify the selected region we used Vision framework ( ML framework provided by apple to detect the object ). The vision framework give us the boundary of the text region ( i.e frame - x,y,width,height ).  Then using the above region we crop the selected region and pass it to the next module. Module II : Recognize the text To recognize the text we ...
