Null Conditional Check in C# 6
Tags: csharp

Title: Exploring the Power of C# Null Conditional Check in C# 6

Introduction:
C# 6 introduced a valuable feature called the Null Conditional operator, which enables developers to write safer and more concise code when dealing with potential null values. This powerful feature simplifies null checking and reduces the chances of encountering dreaded NullReferenceExceptions. In this post, we will dive into the concept of Null Conditional Check in C# 6 and explore its benefits with clear code examples.

Understanding Null Conditional Check:
Null Conditional Check, denoted by the question mark operator "?." in C#, allows us to safely access properties, methods, and indexers on a potentially null object without having to explicitly check for null first. If the object is null, the Null Conditional operator returns null rather than throwing an exception.

Code Examples:

1. Simplified Property Access:
Consider a scenario where we have a class called "Person" with a nullable property "Name". Traditionally, we would have to check if the person object is null before accessing its name property. With null conditional check, the code becomes significantly cleaner:

```csharp
string name = person?.Name;
```

If the person object is null, the "name" variable will be assigned null, avoiding any potential NullReferenceExceptions.

2. Chained Method Calls on Nullable Object:
Imagine we have a class hierarchy where each class contains a nullable property that needs to be accessed in a method chain. With traditional null checks, we would have to apply multiple if conditions to avoid exceptions. However, using the Null Conditional operator, we can elegantly handle such situations:

```csharp
int? result = obj?.GetProperty()?.Calculate();
```

In this example, if any intermediate object (obj or GetProperty()) is null, the entire chain evaluation stops and the result is assigned null.

3. Conditional Invocation of Methods and Indexers:
Null Conditional Check also supports conditional invocation of methods and indexers on nullable objects. This is especially useful when dealing with collections or complex data structures. Let's see an example:

```csharp
List<int> numbers = null;
int count = numbers?.Count() ?? -1;
```

In this case, if the "numbers" object is null, the Count() method will not be invoked, and the count variable will hold -1 instead.

Conclusion:
The Null Conditional Check introduced in C# 6 provides a concise and safe way to handle potential null values, reducing the likelihood of NullReferenceExceptions. By leveraging this feature, developers can write cleaner and more expressive code, focusing on essential logic rather than tedious null checking. So, next time you find yourself dealing with nullable objects, remember to harness the power of Null Conditional Check and improve the reliability of your code. Happy coding!

Integer Overflow
Tags: beginners, programming, c, tutorial
Published: 2024-02-06 11:27:00

# Integer Overflow 

Integer overflow is a problem that occurs when we have a constraint in the maximum size of an integer and we have a result that goes through that maximum size, let me demonstrate in base 10.

Let's say we have a maximum of 3 base 10 digits, so the largest value we can have is 999, but let's try to go over the limit and understand better by adding 1 to the 999, we obviously know that the result should be 1000, but in our constrained environment we get the value 0.... Why is that?

It is simple, it did the normal addition algorithm to our number, so it added 1, to the last digit, and got 10, then the carry was 1, so it added, 9 and 1 again, same thing, the result is 0, and there is a carry of 1, and in the last digit, we added 1 to 9, got a carry of 1, and the value was zero, but we can't add the carry digit to the front of the number, since our number is constrained to 3 digits, therefore we forget about the carry, and set a `overflow flag` in the processor.

This is the same thing that happens in a computer. so let's look at this example in C:
```c
#include <stdint.h>
#include <stdio.h>

uint8_t get_overflow(uint8_t num)
{
    uint8_t max = 255;

    return max + num;
}

int32_t main(void)
{
    printf("%u\n", get_overflow(1));
    printf("%u\n", get_overflow(2));
    printf("%u\n", get_overflow(3));
    return 0;
}
```

Here, since we are using an 8 bits unsigned integer, it means that the we can only represent the largest 8 bit unsigned number, which is 255 (it goes from 0 to 255), and if we try to add one to 255, it wraps up and starts counting again from 0.

But something weird happens if we are using signed numbers, see the following example:
```c
#include <stdint.h>
#include <stdio.h>

int8_t get_overflow(int8_t num)
{
    int8_t max = 127;

    return max + num;
}

int32_t main(void)
{
    printf("%d\n", get_overflow(1));
    printf("%d\n", get_overflow(2));
    printf("%d\n", get_overflow(3));
    return 0;
}
```
Obs: Here we must remember that since the sign takes one bit, the range of the unsigned integer is cut in half, so it goes from -128 to 127.
If you run the code above you might have had a surprise, the value is not zero, but the smallest number the type can hold (-128), why is that??

That happens because of how signed numbers are stored in binary, they are stored in a way we call `two's complement`, for ease of operating on top of it.

## Two's complement??

Two complement is a rather simple way to representing binary numbers, you can follow the following algorithm to test it out.
Input: a number x

1. flip all of 'x's bits (if it is one, it becomes 0, if it is zero it becomes 1)
2. Add one to the number

So let's look at a quick example with the number 3, that in binary is 0011, flipping all the bits, would be 1100, and then adding one would be 1101

Because of this odd representation, that we are getting the number -128 when it overflows. And the cool thing is, that we can use the same circuit for adding and subtracting if we are using two's complement.

Navigating the Chasm: A Comprehensive Guide to the Crossing the Chasm Framework
Tags: framework
Published: 2024-02-06 11:06:13

The [Crossing the Chasm framework](https://www.predictableinnovation.com/methods/crossing-the-chasm-framework-mistakes), developed by Geoffrey A. Moore in his influential book of the same name, provides a strategic approach for successfully bringing innovative products to market. The metaphorical "chasm" represents the gap between early adopters and the early majority in the technology adoption lifecycle.

In the early stages of a product's life cycle, it often attracts the attention of innovators and early adopters who are enthusiastic about embracing new technologies. However, the challenge lies in crossing the chasm to reach the larger, more pragmatic early majority market segment. This transition is marked by significant differences in mindset, needs, and preferences between the early adopters and the early majority.

The framework identifies key stages and strategies for navigating this challenging transition. It begins with targeting a specific niche market composed of early adopters who are willing to take risks and experiment with new solutions. Once a foothold is established in this niche, the focus shifts to developing a compelling value proposition that addresses the specific needs and concerns of the larger early majority audience.

Communication plays a crucial role in successfully crossing the chasm. The messaging should shift from emphasizing innovation and uniqueness to highlighting reliability, scalability, and practical benefits. This resonates more with the early majority, who prioritize proven solutions and want to see tangible results.

Building partnerships and alliances is another essential element of the Crossing the Chasm framework. Strategic collaborations can provide access to distribution channels, enhance credibility, and facilitate adoption among the early majority.

Ultimately, the framework emphasizes the need for a clear understanding of the target market's dynamics and the ability to adapt strategies based on the unique challenges posed by crossing the chasm. Successfully navigating this transition is a pivotal factor in achieving mainstream market success for innovative products and technologies.

Polyfill for map, filter and reduce in JavaScript
Tags: javascript, webdev, frontend, programming
Published: 2024-02-06 11:04:15

## **_Hey there!!_**

If you are a JavaScript developer or learner then you must have come around these 3 widely used array methods : map, filter and reduce.

If you are a consistent learner or preparing for interviews, this article might help you to go little bit deep down in JS. Before we see how Polyfills are implemented lets define what a Polyfill is.

> **Polyfill :** A piece of code to implement a specific functionality so that browsers provide them natively. Suppose a browser doesn’t support a particular String method, in that case developers could write their own implementation for the same.

Now, let’s dive into some coding!!

In JavaScript if you want add a method to an object we can do it by using the **prototype**. Suppose, you have an object named Person and you wish to add a method **_getName()_**, then you can do that by following piece of code.

```
Person.prototype.getName = function() {
  //code goes here
}
```

Now, using the same syntax we are going to implement our polyfills.

If you see the syntax of **_map()_**, **_filter()_** and **_reduce() _**functions, they take a callback as an argument. And that callback function takes 3 arguments.

1. currentValue
2. index of currentValue [Optional]
3. array [Optional]

- 
**Polyfill for map : customMap()**

```
Array.prototype.customMap = function(callback) {
  const arr = this;
  const result = [];
  for (let i = 0; i < arr.length; i++) {
    const val = callback(arr[i], i); //pass 'i' for index
    result.push(val);
  }
  return result;
};

const arr = [1,2,3,4,5];
console.log(arr.customMap((ele, index) => {
  console.log(index);
  return ele*2;
}))
//Output
//0 1 2 3 4
//[2,4,6,8,10]
```
-----------------------------------------------------------------
- 
**Polyfill for filter : customFilter()**

Polyfill for filter is same as map with the only difference that we just need to add array element into the result if the callback returns true.

```
Array.prototype.customFilter = function(callback) {
  const arr = this;
  const result = [];
  for (let i = 0; i < arr.length; i++) {
    if(callback(arr[i], i) === true);
      result.push(arr[i]);
  }
  return result;
};

const arr = [1,2,3,4,5];
let result = arr.customFilter((ele) => {
  return (ele%2 === 0);
})

console.log(result);
//[2,4]
```
-----------------------------------------------------------------
- 
**Polyfill for reduce : customReduce()**

Polyfill for reduce is little different than the previous ones. It takes one more argument named as **initialValue**.

`array.reduce(callback(result, currentValue, index), initialValue = 0)`

```
Array.prototype.customReduce = function (callback, initialValue = 0) {
  const arr = this;
  let result = initialValue;
  for (let i = 0; i < arr.length; i++) {
    result = callback(result, arr[i], i);
  }
  return result;
};

const arr = [1, 2, 3, 4, 5];
let result = arr.customReduce((res, arr) => {
  return res + arr;
}, 3);

console.log(result);
//18
```
