Navigating JavaScript Objects: Different Iteration Methods 🚀
Tags: javascript, tutorial, programming, coding
Published: 2023-07-29 06:02:06

In JavaScript, objects don't support native iteration, preventing us from using popular "for...of" loops designed for arrays. Similarly, methods like **map()** or **forEach()** don't work since they are specific to arrays.

However, fear not! There are alternative ways to iterate through JavaScript objects effectively. Let's explore two of them below:

## Using "for...in" Loop:
The "for...in" loop comes to the rescue when dealing with JavaScript objects. This loop allows us to iterate through the enumerable properties of an object effortlessly. Here's an example of how you can use the "for...in" loop for this purpose:

```  javascript
const myObject = {
  name: "Bilal",
  age: 25,
  occupation: "Senior Software Engineer",
};

for (let key in myObject) {
  console.log(key, myObject[key]);
}
```

## Utilizing "Object.entries()":
Another approach is to use "Object.entries()". This method returns an array containing arrays of key-value pairs representing the enumerable properties of the object. We can then use array methods like "map()", "forEach()", or even "for...of" loops to iterate through the returned array:

```javascript
const myObject = {
  name: "John",
  age: 30,
  occupation: "Developer",
};

const entries = Object.entries(myObject);

entries.forEach(([key, value]) => {
  console.log(key, value);
});
```
Both methods provide effective ways to loop through JavaScript objects, enabling us to handle their properties efficiently. So, whether you prefer the simplicity of "for...in" or the versatility of "Object.entries()", these techniques will empower you to navigate through objects with ease. Happy coding!

What is Lorem Ipsum?
Published: 2023-07-29 05:49:39

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
Why do we use it?
Published: 2023-07-29 05:49:27

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

TIL: Sinatra Public Folder
Tags: ruby, sinatra, webdev, backend
Published: 2023-07-29 05:45:42

## Intro

I was attempting to link a style sheet and render an image in my Sinatra project

I went with the ole reliable for linking a stylesheet and rendering an image.

```html
<link rel="stylesheet" type="text/css" href="/stylesheets/style.css" />

<img src="/assets/image_name.jpg" alt="" />
```

## Solution

It didn't work. I got an unknown error on _better_errors and I didn't know what to do. After reading over the Sinatra documentation, I found out that Sinatra looks at a folder named public to store stylesheets and media. This is when I had to modify my folder structure.

On project root, I created a folder named public and added my folders: stylesheets and assets. Images were rendered and stylesheet was linked.

Securing files/images in laravel
Published: 2023-07-27 11:01:24

If you put a file in public folder it will be accessible to everyone who knows the file name, because nginx/apache rewrite rules used by Laravel only apply to non-existing files, so Laravel won't even be run when accessing an existing file.

So, you still have to put restricted files somewhere out of public folder. Maybe in storage folder, but ultimately it doesn't matter.

And yes, you should just use Response::download.

**Make a small FileController:**

```
class FileController extends Controller {
	public function __construct()
	{
		$this->middleware('auth');
	}

	public function getFile($filename)
	{
		return response()- 
                 >download(storage_path($filename), null, [], null);
	}
}
```
The fourth argument of download() being null prevents the Content-Disposition header being set to attachment. So your browser won't ask you save the file, but just show it.

**Then add a route:**

```
Route::get('file/{filename}', 'FileController@getFile')->where('filename', '^[^/]+$');
```
And that's it. Now, your authenticated users can download files from storage folder (but not its subfolders) by calling http://yoursite.com/file/secret.jpg. Add you can use this URL in src attribute of an image tag.

Understanding Sequence Slicing in Python: Lists, Strings, Tuples, and Ranges
Tags: python, programming, learning, computerscience
Published: 2023-07-29 04:38:46

In Python, slicing is a powerful feature that allows you to extract a portion of a sequence. It can be applied to various sequence types, such as lists, strings, tuples, and ranges. Each of these sequence types handles slicing in a slightly different way, and it's important to be aware of their characteristics and time complexity.

📜 List Slicing:
Lists are mutable, ordered collections, and slicing a list creates a new list containing a copy of the specified elements. The time complexity of list slicing is O(k), where k is the size of the slice (the number of elements in the slice).

📜 String Slicing:
Strings are immutable sequences of characters, and slicing a string creates a new string containing a copy of the specified characters. The time complexity of string slicing is also O(k), where k is the size of the slice (the number of characters in the slice).

📜 Tuple Slicing:
Tuples are immutable, ordered collections, and slicing a tuple also creates a new tuple containing a copy of the specified elements. Like lists and strings, the time complexity of tuple slicing is O(k), where k is the size of the slice (the number of elements in the slice).

📜 Range Slicing:
Ranges are immutable sequences representing arithmetic progressions of integers. Unlike other sequence types, slicing a range does not create a new range; instead, it creates a new range-like object with a new start, stop, and step based on the slice parameters. The time complexity of range slicing is O(1), regardless of the size of the slice, because the new range is created directly using the start, stop, and step values.

Here are some examples to illustrate slicing with different sequence types:

```python
# List Slicing
my_list = [1, 2, 3, 4, 5]
slice_list = my_list[1:4]  # Creates a new list [2, 3, 4]
print(slice_list)

# String Slicing
my_string = "Hello, World!"
slice_string = my_string[7:]  # Creates a new string "World!"
print(slice_string)

# Tuple Slicing
my_tuple = (10, 20, 30, 40, 50)
slice_tuple = my_tuple[:3]  # Creates a new tuple (10, 20, 30)
print(slice_tuple)

# Range Slicing
my_range = range(1, 10, 2)
slice_range = my_range[1:4]  # Creates a new range-like object range(3, 7, 2)
print(slice_range)
```

In conclusion, understanding sequence slicing is crucial for working with lists, strings, tuples, and ranges in Python. Each sequence type has its own slicing behavior, and knowing the time complexity of slicing can help you make informed decisions when dealing with large datasets or performance-critical operations. Happy coding! 🚀
Day 1 of #100 days of health and study.

> Life is what happens when you are busy making other plans. - John Lennon

A lot has happened since 2020... changed my focus, not my desire.  Finally, I have a grove back since the pandemic.  Inspired by the 100 days of coding, which I'll eventually do, but for now I'm doubling down on what I know - Project Management. 

I do like being a servant leader in the industry I am in; however, I think I'll be more fulfilled in the IT industry.  Why?  I like it better.  They put money into technology.  Duh?  You would be surprised how many industries don't understand technology in 2023.  They understand capacity better, and they understand Project Management better. 

Always working as a hybrid project manager, it is a unique position to do both traditional project management and adaptive project management in software development and finance.  Finding my voice in a sea of chaos.  What do you do for a living?  Organize chaos. 

I'm creating #100 days of health and study for myself.  Trying to get some momentum, linking exercise to studying PMP.  Wish me luck!  I'll try and post as much as I can. 

All the best, Joe
