Swift vs Objective-C (What to choose and where to choose)

Good Morning Fellas,

Today we’ll be talking about iOS development! Don’t get too excited guys because this is not a hands-on for an iOS application development but you can consider it kind of prerequisite for development in iOS.

As we all know that what we require to start developing a new application is some sorts of technologies and some languages.

So what you’ll be needing for an iOS application development is as follows:

-> MacOS (VM will also do, just make sure you have enough R.A.M.)
-> xCode 7.0 ( preferred )
-> A language to code on (Swift or Objective-C )

So now let's have a look at what swift is and what Objective-C is, and what should you choose to start with the development of iOS application. Here I’ll try to cover all the pros and cons of both the languages and which one you have to choose is wholly your decision based on the demands of your project.

So let's begin with a brief definition of these. Here are the wiki definitions,

** Swift is a general purpose, multi-paradigm, compiled programming language created for iOS, OS x. watchOS, tvOS and Linux developed by Apple Inc.

**Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language used by Apple for OS X and iOS operating systems, and their respective API’s.

First of all, I want to tell you that Objective-C is not C#( C-sharp or C-hash). Objective is bind with Cocoa whereas C# is bind with .NET / WPF / LINQ . So I guess that gives you a not so vivid but a vague idea that how they are different.

If you want to know more about Objective-C vs C# then do let me know in the comments.

Let's first dive into what is Cocoa and Cocoa Touch and why they are so important to Objective-C and Swift as well. The term Cocoa is used to refer to any object or class that is based on the Objective-C runtime and inherits from the root class NSObject.

Just as java.lang.Object is the root class of Java same goes for Objective-C, Cocoa and Cocoa Touch are the defacto standard libraries for Objective-C, where Cocoa includes Foundation and AppKit framework which are used for developing apps for OS X whereas Cocoa Touch which includes Foundation and UIKit are used for developing apps for iOS.

Swift is designed with modern Technologies i.e. with features like safe, performant based code and is way faster then Python(Sorry if it hunted you but yes this is the truth), swift is 3.9 times faster than Python as claimed by Apple in WWDC but yes every stone has its value in different places so this speed does not mean that Python can be replaced by swift and also the programmers love for Python won’t die( I cannot start discussing Python since it’ll end up making this a pretty long blog)

So If you want to code for application which interacts on with real world application and 3rd party plugins or services so for that can use Swift whereas on the other hand if you want to develop system apps which are more oriented towards interaction with a compiler and basic operating system then I’ll suggest you go for Objective C [Also for the speed thing Swift is approximately 1.5 times faster thanObjective-CC but as described earlier it all depends on the state or environment you are working on].

For Swift and Objective pros and cons you can refer to this link:

Hope you had a great reading experience, feel free to drop some suggestions in the comment section below.

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
