Dictionary<TKey, TValue> vs Hashtable: A Battle of Collection Titans in C#
Tags: dotnet, csharp, tutorial, programming
Published: 2023-06-23 09:23:49

Hey there, knights of the keyboard! 🖐️

Today we will be diving into a duel between two heavyweights of the C# collections world. In the left corner, we have our generic strongman, `Dictionary<TKey, TValue>`, and in the right, the flexible and robust underdog, `Hashtable`. Who will prevail in this contest of performance, type safety, and flexibility? Let's find out! 🔥🔥

**Round 1: Type Safety**

We all know how vital type safety is in our coding adventures. Let's see our contenders in action:

```
Dictionary<int, string> dictionary = new Dictionary<int, string>();
dictionary.Add(1, "C#");
dictionary.Add(2, "Java");
dictionary.Add(3, "Python");

foreach (KeyValuePair<int, string> item in dictionary)
{
    Console.WriteLine($"Key: {item.Key}, Value: {item.Value}");
}
```
In this example, we created a `Dictionary<TKey, TValue>` with key as int and value as string. We added some elements to the dictionary and printed them. It's type-safe, and the code looks clean and efficient.

`Hashtable`, on the other hand, is a little wild and free, accepting any object for key and value. But beware the risk of runtime exceptions if you make an assumption about the type!

```
Hashtable hashtable = new Hashtable();
hashtable.Add(1, "C#");
hashtable.Add("Two", 2);
hashtable.Add('3', "Python");

foreach (DictionaryEntry item in hashtable)
{
    Console.WriteLine($"Key: {item.Key}, Value: {item.Value}");
}
```
In this example, we created a `Hashtable `and added different types of keys and values. The flexibility is nice, but boxing and unboxing operations could impact performance.

**Round 2: Performance**

Speaking of performance, `Dictionary<TKey, TValue>` generally packs a more powerful punch, offering faster operations for adding and fetching elements. However, remember that boxing and unboxing in Hashtable can be a performance bottleneck.

Point to `Dictionary<TKey, TValue>` for maintaining its composure in the face of performance pressure!

**Round 3: Flexibility**

Hashtable strikes back! It's an old-school contender, coming from non-generic collections, meaning it can take any object as key and value. `Dictionary<TKey, TValue>`, while mighty, can only accept the types it was declared with.

Point to Hashtable for its sheer adaptability!

**Final Bell 🛎️**

So, knights, it appears we have a victor. For most modern C# applications, Dictionary<TKey, TValue> offers a stronger, safer, and more performant solution. But remember, each tool has its place, and there might be times when Hashtable's flexibility shines. Be mindful of your needs and choose wisely!

I hope you enjoyed this clash of C# collection titans. Have a great day!🖖💻

How to use named arguments in TypeScript functions?
Tags: typescript, javascript, programming, cleancode
Published: 2023-06-23 09:14:02

If you are familiar with the **keyword** / **named** **arguments** in programming languages such as Python, Ruby and PHP 8, you probably wonder if the same can be achieved in TypeScript.

This is an excellent question. We are aware that [named parameters](https://en.wikipedia.org/wiki/Named_parameter) / named arguments drastically help the readability of the code. With keyword arguments, we can directly tell what the mentioned argument does in the function call.

Use the object destructuring on the function parameters.

Like this 👇

```typescript
function invertSentence({
  sentence,
  doesFormat
}: {
  sentence: string;
  doesFormat: boolean;
}): string {
  if (doesFormat) {
    return sentence;
  }

  // logic ...

  // split into two segments
  const [stringOne, stringTwo] = sentence.split(
    ". "
  );

  // rebuild the sentence
  const rebuiltString = `${stringTwo} ${stringOne}`;

  return rebuiltString;
}
```

And then, you will be able to mention the required properties which will be the "named arguments".

```typescript
invertSentence({ 
  sentence: 'TS makes my job easier. Writing clean code avoids me a headache',
  doesFormat: false
});
```


## Conclusion

In conclusion, TypeScript doesn't offer named arguments natively like what [PHP 8 does for instance](https://www.php.net/manual/en/functions.arguments.php#functions.named-arguments). 
However, thanks to the power of TS's types, we can the types to force our functions' parameters to receive the arguments with their mentioned property names for improving the readability of our code.
What is Layouts in Flutter?
Tags: flutter
Published: 2023-06-23 09:09:06

In Flutter, layouts refer to the arrangement and positioning of widgets to create the user interface (UI) of a mobile or web application. Flutter provides a variety of layout widgets that allow developers to structure and organize the visual elements of their app in a flexible and responsive manner.

**Some commonly used layout widgets in Flutter include:**

**1. Container:** A versatile widget that allows customization of its child widget's position, size, and appearance. It provides properties for setting margins, padding, borders, and background color.

**2. Row and Column:** These widgets are used to arrange child widgets horizontally (in a row) or vertically (in a column). They automatically handle the positioning and spacing of their children based on the specified layout constraints.

**3. Stack:** This widget allows widgets to be stacked on top of each other, enabling complex and overlapping UI designs. The stack widget places its children relative to the edges or the center of the stack.

**4. Expanded and Flexible:** These widgets are used to control the flexibility and proportion of space occupied by child widgets within a parent container. They are commonly used in combination with rows and columns to create responsive and dynamic layouts.

**5. GridView:** It arranges its children in a grid pattern with a specified number of rows and columns. The GridView widget is useful for displaying grids of images, icons, or other widgets.

**6. ListView:** It displays a scrollable list of children widgets, allowing content to be displayed in a scrollable manner when there are more items than can fit on the screen. ListView widgets can be customized to support different scrolling directions, item builders, and separators.

These are just a few examples of the layout widgets available in Flutter. Developers can combine these widgets and apply different properties and constraints to achieve the desired UI layout and structure for their application. By obtaining [Flutter Certification](https://www.edureka.co/flutter-development-certification-course), you can advance your career as a Flutter. With this course, you can demonstrate your expertise in Flutter widgets, state management, asynchronous programming, and network integration, along with hands-on experience to build real-world applications, many more fundamental concepts, and many more critical concepts among others.

Flutter's flexible and powerful layout system allows developers to create visually appealing and responsive user interfaces for mobile and web applications. It provides the flexibility to adapt to different screen sizes and orientations, making it easier to build apps that work seamlessly across various devices.
Internals of PostgreSQL: Chapter 02: Process and Memory Architecture
Tags: apacheage, postgres, database
Published: 2023-06-23 08:50:05

The process architecture of PostgreSQL is explained at the beginning of the chapter. It outlines the various steps involved in running a PostgreSQL server, including:

**1) Postgres Server Process:** This parent process, formerly referred to as the postmaster in earlier iterations, is in charge of overseeing the whole PostgreSQL server. Prior to starting background processes, replication processes, and background worker processes, shared memory is allocated. It runs backend processes to respond to client requests and watches for requests for client connections.

 **2) Backend Processes:** Backend processes are created by the postmaster to respond to requests from linked clients. Through a TCP connection, each backend process connects to a single client and runs until the client disconnects. Depending on the chosen maximum number of connections, numerous clients may connect at once to each backend process's single database.

**3)  Background Processes:** PostgreSQL has a number of background processes that carry out different database management functions. These procedures include, among others:

-      Background Writer: Dirty pages from the shared buffer pool 
are written to persistent storage by the background writer.
-      Checkpointer: Performs checkpoint operations to guarantee data consistency and recovery.
-      AutoVacuum Launcher: Launches the processes used by the autovacuum workers to perform routine vacuuming.
-      WAL Writer: Records information from Write-Ahead Logs (WAL) in persistent storage.
-      Statistics Collector: Database activity statistics are gathered by the statistics collector.
-      Logging Collector (Logger) : Writing error messages to log files is done by the logging collector (logger).Executes archiving logging operations.

The following section of the chapter covers PostgreSQL's memory architecture, which can be divided into local memory and shared memory areas:

**Local Memory Area:** For the purpose of processing queries, each backend process allocates a separate local memory area. Sorting, maintenance tasks, and temporary tables are just a few examples of the specialized uses for which this area is divided into fixed or variable-sized sub-areas.

**Shared Memory Area:** The PostgreSQL server allots a portion of memory for shared use by all server processes when it first starts up. It consists of a number of sub-areas, including the commit log for keeping track of transaction statuses, the WAL buffer for buffering WAL data before writing it to storage, and the shared buffer pool for loading and using table and index pages.
