Building your own Design Pattern


Hybrid MVC + MVVM


Ever so often, developers face the dilemma of choosing from multiple design patterns for their code. Yes, there are deadlines to adhere to, there are changing needs of the product, the code needs to be testable and what not! But as a developer, you always want to write code that’s scalable, modular and easy to debug for any issues, if not bug-free now — not an easy task by any means! You have to be very smart in locking down the foundation for your code. After all, it’s only on a strong foundation, that you can build a scalable structure.

What you’ll learn in this post:

  • What MVC, MVVM etc. are all about and some of their shortcomings
  • Why design patterns are an important part of development lifecycle
  • How you can alter some of the aspects of these patterns to come up with your own version, as per your use case
  • How we design high quality, stable features at Hike using our Hybrid design pattern

MVC

The standard MVC pattern has three major components:
Model — The Model is usually the data source of the system. It interacts with the controller to provide the current state of your database. Data can reside locally in your system, or fetched from the servers. In any case, the model provides you with the relevant information.
View — View is what you see on your screen. All the UI components together constitute the view. In standard MVC implementations, views are usually pretty dumb with no business logic to them. They get directions from the controller and populate themselves accordingly. Similarly, any actions that the user takes on the UI are passed on to the controller to handle.
Controller — This is where all the action happens! The Controller takes care of multiple things. Firstly, it instantiates both the Model and the View components. All business logic in response to user actions, asking the model to update itself, and listening to any changes in the model that might need refreshing the view happens in the controller!
A typical MVC interaction system

Few details of MVC:

  • The Model and the View only interact with the controller, and NEVER talk to each other directly. All communication happens via the Controller only.
  • As a result, the Controller usually becomes one massive class, handling multiple responsibilities.
  • All components are tightly coupled with each other. This makes reusability of these components difficult, replacing any of them later on, or making changes to them is a tough ask!
  • Writing tests and debugging intricate bugs in one massive controller class can be tricky.

MVVM

The following components form the main aspect of this pattern:
Model — The Model in MVVM works similar to MVC. It gives you the data you need, which can be present locally, or fetched from servers behind the scenes, just like in MVC.
View — Implemented as a View/View Controller subclass, the view here talks to the view model to gather all information, that is needed to display all UI components.
View Model — This is the major differentiating component from a MVC. The view model acts as the intermediate between the view and the model. Unlike MVC, the model is owned by View Model.
MVVM interaction system
Few details of MVVM:
  • The view here is a UIKit independent implementation. The view controller itself can be treated as the view component.
  • There’s complete isolation of the Model and the View, which makes them loosely coupled with one another.
  • The View Model invokes all changes to the model and listens to any changes that the Model makes behind the scenes.
  • The View and View Model interact via bindings, so any change in the Model notifies the View Model, which in turn updates the View.
  • This clearly helps break the massive controller of MVC, with the View and View Model now sharing responsibilities of updating UI and the coordination between components, respectively.

Discussion:

As we saw earlier, while MVC works for small contained components, it fails to meet the requirements of an evolving and growing product. Adding new code to an MVC system is difficult without breaking existing parts. Debugging issues in an MVC system can be time consuming, and sometimes can lead you clueless, as your controller is taking care of a million things at the same time.
While MVVM was great in taking care of some of those concerns, we thought there was still scope for some more modularity, some more scalability. We could do better! We could break these components into further subcomponents. The idea was to evolve the architecture in such a way that more and more components became reusable. It should be easier to replace one component without affecting the whole system.
So we went through these and a few more design patterns like VIPER, RIBs, evaluated their advantages/disadvantages, and compared them with our use case. We went through the common limiting factors encountered while scaling our systems. The final pattern we came up with was a hybrid version of the MVC and MVVM patterns.

Hybrid MVC and MVVM pattern

The following diagram shows the various components and their interaction within this pattern:
Let’s go over the functionalities of each of these:
  • Data Source — The Data Source is responsible for providing data to the entire system. This can be any generic class conforming to a protocol that is used by the Controller to ask for data. The data can be stored internally in any way. All that detail is internal to the implementation of Data Source. Conforming to a protocol ensures that we can replace the data source implementation without affecting any other component. All we need is for the new class to conform to the data source protocol, and we won’t have to change any other aspect. Given the Controller owns the Data Source, any changes in the underlying data are conveyed to the Controller that can then initiate appropriate action for it.
  • Controller — The controller is at the centre of it all though much of its responsibility is to coordinate other items to enable them to function together. Usually this is a View Controller subclass, which is initialised with a Data Source object. Suppose we have to implement a chat screen, which shows all messages and has ability to send messages. The main chat view controller will act as the Controller. The table view to show all messages would be a part of the chat view controller. The initialisation would look something like this:
Controller Initialisation
  • View — The independent UI components can be separated out in a separate View layer. The Controller instantiates and holds references to them.The View is passed as a View Model object that the View uses to populate itself. In case of our example, the cells of the table View can be initiated with this pattern, where we pass them a View model object to populate with:
View Initialisation
  • View Model — The View Model is instantiated by the Controller for the independent View components that need not be part of the Controller class. Identifying such View-View Model components can help keep your Controller light and code modular. The View Model is initialised with a Model object that contains all information needed by the view to populate itself. The other important aspect to it is that we don’t expose class names anywhere, we only expose id<some_protocol> type of objects. This makes it easier to replace these components without affecting any other components:
View Model Initialisation
  • Action Handler — The view reports all user actions taken on it back to the Controller. In order to keep the Controller independent of the business logic behind all such user actions, we place all this logic in a separate component called Action Handler. This component gets the information regarding the type of action (say single touch, long press etc.) from the Controller, and applies all business logic to handle that event:
Action Handler
It is important here to note that while the Action Handler has all the logic to execute in response to any user action, it doesn’t actually perform any UI operations itself. Any UI operation, be it adding/removing a subview, or pushing/presenting any other View Controller should only be done by the Controller. As we can see in the above snippet, the Action Handler returns a Response Model object. This object contains all information about the kind of UI task that needs to be performed:
Response Model
Based on the value of the action type, the Controller picks the appropriate UIView or UIViewController from the Response Model object and performs necessary operations on it. Thus, there is a clear separation of responsibility between the Controller and the Action Handler.

Conclusion:

This hybrid design pattern offers us multiple advantages over other patterns. When we applied it in app
  • Our Controller classes have become very light weight, with its only responsibility being that of connecting all other components together. This has improved the testability of this component
  • The Data Source kept the implementation of how data is stored abstracted, and this could be changed at any later point of time without affecting other components
  • The Views/ View Model become reusable as they were only identified by adhering to a protocol
  • Unit Testing becomes easier and could be done only for classes with a business logic in them.
  • Most if-else checks in the code were minimised by using factory pattern to link different components.
  • The readability of the code increased, helping other developers understand what’s going on in your features :)
Impact at Hike:
  • The architecture helped us improve the overall app stability. We started implementing it at one place at a time. We began with chat, and this helped us make chat more robust and easy to work upon. For instance, here’s how our app stability grew over time:
  • We were able to experiment internally with different versions of chat, as it was easy to just plug and play different components. This helped us make decisions faster.

Key takeaways:

  • The decision of choosing a design pattern will go a long way with you. Make sure you give enough thought to it
  • There are enough patterns out there, but you don’t have to necessarily choose from them. Feel free to come up with your own version based on your requirements

iPhone XS v/s iPhone X: Is it worth an upgrade?


Apple iPhone XS v/s iPhone X: The differences
As the successor to last year's tenth-anniversary edition iPhone X, Apple has launched the iPhone XS.
The new iPhone retains the edge-to-edge design of its predecessor but comes with an improved display and under the hood upgrades.
And given the iPhone XS is priced at $999, the same as iPhone X, the question is if it is worth the upgrade.
Here's a specifications-wise comparison.
In context: Apple iPhone XS v/s iPhone X: The differences

13 Sep 2018iPhone XS v/s iPhone X: Is it worth an upgrade?

As the successor to last year's tenth-anniversary edition iPhone X, Apple has launched the iPhone XS.
The new iPhone retains the edge-to-edge design of its predecessor but comes with an improved display and under the hood upgrades.
And given the iPhone XS is priced at $999, the same as iPhone X, the question is if it is worth the upgrade.
Here's a specifications-wise comparison.


Design At a glance


In terms of design, there's nothing new on the iPhone XS. So, you still have an edge-to-edge display with a notch that houses the front camera and Face ID module.

On the back, there's a dual camera setup and glass panel that enables wireless charging.

However, iPhone XS is now IP68 rated (iPhone X is IP67 rated) and is covered in a tougher glass.
All about the screen
DisplayAll about the screen

The iPhone XS has same 5.8-inch OLED Super Retina display with 458ppi of pixel density and 2,436x1,125 resolution.

However, Apple says the new display now offers 60% greater dynamic range of colors than its predecessor.

Further, the iPhone XS display also gets support for HDR 10, Dolby Vision, 120Hz touch sensitive, and the less-talked-about 3D Touch which debuted with the iPhone 6S.




Camera

For the shutterbugs and selfie lovers

In terms of camera, like the iPhone X, its successor sports a 12MP (f/1.8) wide-angle camera with OIS, 1.4-micron pixels, paired with a 12MP (f/2.4) telephoto lens with OIS and 2x optical zoom.

However, Apple has offered a faster sensor, a new image processing chipset that offers Smart HDR.

Up front, iPhone XS has the same 7MP TruDepth RGB camera with f/2.2 aperture.




Internals

All the important stuff

The most important upgrade is the new 7nm A12 Bionic chip which has a 6-core CPU, and a 4-core GPU.

The chipset comes paired with a new Apple-designed Neural Engine which can perform 5 trillion operations per second (600 billion operations on the older iteration).

Further, the new processor is 15% percent faster and 40% more power-efficient than the A11 chipset on iPhone X.






Sensors & Software

Lifeblood of your smartphone

In terms of software, there's the standard set of sensors you expect on a flagship smartphone.

Further, Apple's Face ID which debuted with the iPhone X, has now improved, thanks to the new Neutral Engine.

In terms of software, the iPhone XS will run iOS 12 out-of-the-box while iPhone X will get it as an OTA, starting September 17.

Battery & Connectivity

Staying connected

In terms of battery, Apple has said the iPhone XS will last half an hour more than iPhone X which packs a 2,716mAh battery.

Further, all connectivity options remain the same as seen on the iPhone X except for two major changes - Gigabit LTE that offers up to 1Gbps speed on 4G and support for dual SIMs (eSIM+Physical SIM).
]





    There's also a taller 6.5-inch iPhone XS Max
    Alongside the iPhone XS, Apple has also introduced a new 6.5-inch iPhone XS Max. The bigger iPhone packs the exact same specs as the iPhone XS but comes with a higher 2688x1242 resolution, and is claimed to last 60 minutes more than its smaller sibling.



Our result

How things stack up!

The iPhone XS is surely the most advanced iPhone yet. There's a new A12 chipset that will offer improved performance, better image processing, and graphical rendering.

However, starting at $999, like its predecessor, the new iPhone isn't much of an upgrade over the iPhone X.

That said, if you're on an iPhone 8 or older, the leap to iPhone XS will be worth it.




    Pricing and Availability
    The iPhone XS and iPhone XS Max will be offered in 64GB/256GB/512GB storage configurations with prices starting at $999 and $1099, respectively. These iPhones will become available starting September 28 in India.

How Safe Is Healthcare Technology ?

How Safe Is Healthcare Technology From Hackers?

Source: Mass Device
Healthcare technology is evolving more and more each day, with blockchain, telemedicine and 3D printers being used by medical professionals around the country. But one question still remains to be answered: Can this technology be hacked into? If so, that could mean dangerous consequences for medical records, and sensitive information could be compromised. Throughout this article, we’ll examine how security can potentially be threatened by this technology and give tips on how organizations can ensure their information is secure.

Can 3D Printers Be Hacked?

While 3D printing can sometimes take several hours and be extremely difficult when designing products, this hasn’t stopped industries from utilizing it to the best of its abilities. Several companies such as Adidas and GE are using 3D printing to advance production and manufacturing. Using digital files, 3D printers can produce a plethora of three-dimensional solid objects.
Hospitals are taking advantage of this technology to make historic strides in the healthcare industry. 3D printing is creating innovations in the field of radiology, a science helping to diagnose and treat diseases using medical imaging technology. According to the University of Cincinnati, “3D printing is just now come into style across the radiology realm, as professionals can leverage it for educational, research and other purposes.
But are 3D printers completely safe from hackers? As Harvard Business Review points out, closed systems have dominated the 3D printing industry within the last 10 years. This means 3D printers can only be accessed with the manufacturer’s resin and software. But several companies are shifting to a more open system, which allows for many advantages but also threatens security. “Once introduced into an open environment, a virus can spread faster through multiple parties and flows of information than in a closed system,” Harvard Business Review said.
Hackers often target individuals through shutting down servers, corrupting data and breaking into computer databases, but 3D printing takes the possibilities of hacking to new and frightening levels. By corrupting a 3D printer file, hackers can cause product failures and trigger injuries, product recalls and litigations. Researchers across the country are now figuring out ways to combat these cyberattacks and one method of prevention could be as simple as listening to what sounds the 3D printer makes.

Can Blockchain Be Hacked?

Blockchain, which helps keep track of transactions within machines, is already being used by a variety of different industries in groundbreaking ways. From insurance agencies to record companies, blockchain technology is revolutionizing the way industries store and track data. Medical professionals are able to manage data and conduct research more effectively by using blockchain technology. There is even blockchain technology with the ability to track the degree of cleanliness in hospitals by monitoring hand hygiene.
With blockchain networks being used by so many different organizations around the world, do we know whether or not it’s safe from hackers? Blockchain technology is indeed vulnerable to hackers, and there are many avenues within these systems where hackers can strike. Users of blockchain networks are given private keys, which are used to sign account transactions, and if hackers receive access to it, they could potentially steal information and corrupt data. The security of a blockchain platform can be compromised through software errors as well, which occur during the development of software implementation.
Blockchain technology is as susceptible to hackers as any other systems and users need to have the skills necessary to protect themselves from cyber-attacks. There are several apps that can help prevent cyber-attacks in blockchain networks such as Civic, which prevents identities from being stolen, and Biometrics.io, which uses face recognition technology to identify users. Using these tools, companies can keep their networks secure and ensure their data is safe against hackers.

Can Telemedicine Be Hacked?

Telemedicine is becoming more and more prevalent in the medical field, and it’s benefiting citizens from rural communities greatly. There are now even at-home diagnostic tools available such as electrocardiogram ECG devices, which can keep track of heart health and detect when a heart attack is taking place. There are several smartphone apps helping to advance the possibilities of telemedicine such as the recently announced MinuteClinic service by CVS, which allows users to be diagnosed and treated by doctors through a video conversation on their smartphone.
Even though this technology is helping more communities find medical care and providing an easier form of treatment and diagnosis, is it really as safe from hackers as we may think? While telemedicine is considered safer than many other forms of healthcare technology, hackers can still use several types of ransomware to keep the operation of a medical device hostage and steal data.
Ransomware is a technique used by hackers to extract payment or information, in which a target’s computer is locked until the hacker’s demands are met. Ransomware is usually performed through encryption tactics, and hackers typically order to be paid in a form of online currency such as bitcoin. These type of cyberattacks are at an all-time high, and it’s important to know what to do when you’re targeted.
To avoid privacy and security issues, telemedicine networks are required to comply with the HIPAA, which stands for the Health Insurance Portability and Accountability Act. This act helped to make medical records private and keep health information from getting in the hands of hackers. Telemedicine technology is required to abide by HIPAA’s guidelines, which include implementing a system of secure communication, allowing only authorized users to receive access to services and putting safeguards in place to prevent accidental or malicious breaches. By following these rules, telemedicine technology is more secure and fewer cyber-attacks occur.

સાવધાન! ઈયરફોનથી તમને થઇ શકે છે અનેક નુકસાન…….




આપણે લોકો બધી જગ્યાએ ઇયરફોનનો યુઝ કરીએ છીએ. બસમાં કે ટ્રેનમાં અડધાથી વધુ વિદ્યાર્થીઓ જાગતા હોય અથવા સૂઈ ગયા હોય, પણ મોબાઇલમાંથી ગીતો સંભાળતા હોઇએ છીએ.
પણ શુ તમે જાણો કે, વધુ પડતા ઇયરફોન લગાવી રાખવાથી એકસાથે ઘણી તકલીફોનો સામનો કરવો પડતો હોય છે. મુસાફરી દરમ્યાન તો ઇયરફોન કોઈ મુશ્કેલી નથી કરતા, પણ એ પછી ઇયરફોન લગાવી રસ્તા ક્રોસ કરવામાં કે, રસ્તા પર ચાલવાથી અકસ્માતની ઘણી શક્યતા રહે છે.
એક સંશોધનના કહેવા મુજબ તમે જ્યારે ઇયરફોન લગાવી ચાલતા હો ત્યારે તમારી આંખ ભલે બધું જોતી હોય, પણ તમારું મગજ ગીતમાં એટલું પરોવાયેલું હોય છે કે, આંખ અને મગજ વચ્ચેનો સંદેશાવ્યવહાર લગભગ શુન્ય થઈ જાય છે.
આ ઉપરાંત હોર્ન કે, વાહનનો અવાજ તમને સાભળતા નથી. આ કારણે જ ક્યારેક ગંભીર અકસ્માત સર્જાઈ શકે છે. ઘણા આવા કિસ્સા અત્યાર સુધીમાં જોવા મળ્યા હશે.
સરેરાશ છથી આઠ કલાક સુધી યુવાનો કાનમાં ઇયરફોન લગાવતા હોય છે. જોકે એને કારણે સાંભળવાની તકલીફ અને કાનમાં દુખાવો થવાની સંભાવના વધી જાય છે.
ઇયરફોનના ઉપયોગ કરનારાને ડોક્ટરો દૂર રહેવાનું સૂચન કરતા હોય છે. જોકે ઘણા યુવાનો આજે કોલ સેન્ટર અને સેલ્સમાં આઉટસોર્સિંગ કરતી કંપનીઓમાં કામ કરે છે અને તેમને નાછૂટકે લાંબા સમય સુધી કાનમાં હેડફોન ભરાવીને કામ કરવું પડતું હોય છે.
કોઈ ઉપાય નથી કે, જેને અપનાવવાથી મુશ્કેલીઓ ઓછી થઈ શકે. જોકે નોકરીમાં લાંબા બ્રેક લેવા કરતા નાના-નાના વધુ બ્રેક લેવાનું સૂચન આ યુવાનોને આપવામાં આવતું હોય છે.
