Laravel is one of the most popular PHP-based framework for creating database-driven apps.

Laravel is described by its creators as the framework for web artisans. It's based on the MVC (Model-View-Controller) pattern and can be used for easily creating apps for making CRUD (Create, Retrieve, Update, Delete) operations against a database.

Laravel has a large community of worlwide developers around it that creates packages for common web development problems so other developers don't need to re-invent the wheel.

The Laravel team releases a new version each six months. At the time of writing this tutorial, the latest version is Laravel 8 which was released on the 8th Sept 2020.

Throughout this tutorial, we'll be learning how to create a CRUD app with Laravel 8 to create, insert, update and delete products from a MySQL database.

Replacing placeholders in Umbraco's dictionary items
Tags: umbraco
Published: 2021-05-11 07:24:25

Umbraco's [dictionary feature](https://our.umbraco.com/documentation/reference/querying/umbracohelper/#getdictionaryvaluestring-key) is really cool as it allows editors to control the text you have on buttons, in form labels and other places on your website, removing the need to involve a developer in order to change simple sentences.

Today we ran into a scenario where we needed to make some text that was defined in a dictionary item a bit more dynamic. Instead of completely replacing the dictionary item with text directly in the template, we decided to look into replacing values in the dictionary item. This would allow editors to still control the majority of the text displayed.

An easy fix would be to simply perform some kind of replacement on the string returned by the specific dictionary item in whatever template you have. That is, however, not very scalable. Therefore I looked into further improving the UmbracoHelper's `GetDictionaryValue` method with two extension methods:

```c#
public static string GetDictionaryValueWithReplacement(this UmbracoHelper umbraco, string key, string pattern, string replacement)
{
    return GetDictionaryValueWithReplacement(umbraco, key, string.Empty, pattern, replacement);
}

public static string GetDictionaryValueWithReplacement(this UmbracoHelper umbraco, string key, string altText, string pattern, string replacement)
{
    return Regex.Replace(umbraco.GetDictionaryValue(key, altText), pattern, replacement);
}
```

This gives us the possibility to easily reuse the functionality anywhere on the website.

Now, given a dictionary item with the key `Some.Dictionary.Item` and text `This message is super personal for you, %name%. Hope you like it.`, you can use the extension method above in, for example, a template like so:

```c#
@Umbraco.GetDictionaryValueWithReplacement("Some.Dictionary.Item", "%name%", Members.GetCurrentMember().Name)
```

Which will display the following (in my browser, at least):

```
This message is super personal for you, Morten Hartvig. Hope you like it.
```

One could of course make additional methods in order to work with more than one placeholder.. you know, something like:

```c#
public static string GetDictionaryValueWithReplacement(this UmbracoHelper umbraco, string key, IDictionary<string, string> replacements)
{
    var value = umbraco.GetDictionaryValue(key);

    foreach (var replacement in replacements)
    {
        value = Regex.Replace(value, replacement.Key, replacement.Value);
    }

    return value;
}
```

... but that is beyond the scope of what we need so I'll let you play around with that.

In this short post I'd like to show you a smart trick for memoizing results of computations in memory. Sometimes you need to store results of multiple operations in memory for reuse and typically it's done using a `Hash` instance.

E.g. let's say that we have a method called for checking whether a Star Wars character is from the dark side:
```ruby
def dark_side?(character_name)
  StarWars::Character.find_by(name: character_name).dark_side? 		
end
```

The method is heavy, because it needs to run a DB query in order to get a result for a given input, so if we know that there might be a need for calling it many times with the same `character_name` it might make sense to store the result for future use.

Here's one possibility of how the results can be memoized:
```ruby
def dark_side?(character_name)
  @dark_side_cache ||= {}
  
  @dark_side_cache[character_name] = StarWars::Character.find_by(name: character_name).dark_side? unless @dark_side_cache.key?(character_name)		
  
  @dark_side_cache[character_name]
end
```

However, Ruby's `Hash` has a nice [constructor](https://ruby-doc.org/core-3.0.1/Hash.html#method-c-new) variant that allows passing a block.

Check this solution out, isn't it a pure Ruby beauty? 💅
```ruby
def dark_side?(character_name)
  @dark_side_cache ||= Hash.new do |hash, char_name|
    hash[char_name] = StarWars::Character.find_by(name: char_name).dark_side?
  end
  @dark_side_cache[character_name]
end
```

My first talk on Cloud 🤩🥳
Tags: aws, cloudskills, techtalks
Published: 2021-05-11 07:27:40

A few weeks back I cleared my AWS foundation exam. 

![Cleared my AWS Foundation exam](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/54cr89wthgoeunopb2nx.png)

and a week after my exam clearance I gave a session to the web developers who wanted to start their cloud journey. It was an invite-only session.

![Tweet from 5th May 2021; This weekend I am doing a session on - "Introduction to Cloud for web developers" it is an invite-only session.](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/q9jo2426kmskl6s47ue0.png)

This session covered the following topic:

1) Traditional/old way

2) What is Cloud

3) Why cloud

4) Features

5) Components

6) AWS introduction 

7) IAM, S3, EC2, Cloudfront, ACM

This session's focus was to introduce the developers to understand what is cloud, why the cloud is everywhere, and most important where it fits in web developers' day-to-day work.

As there are more than 100 services every cloud provider has which overwhelmed every new-beginner in the cloud world. In this session, I explained how to start, from where to start, and on which service to focus on as a web developer as a beginner.

[Here](https://github.com/Neha/learn-cloud) is the GitHub repo about my plans on the AWS session and [Here](https://github.com/Neha/learn-cloud/blob/main/CloudComputing-NehaSharma.pdf) is the deck which I presented.

## Upcoming session

I am planning a session on **Host your website on S3**

Happy Learning!!

Hey cloud engineering friends! I've just hit publish on another episode in the series about the cloud resume challenge.

If you've not already heard of [the cloud resume challenge](https://cloudresumechallenge.dev/), it's a free, online challenge started by the hero (AWS hero, and general cloud hero) Forest Brazeal to help people get into the cloud by giving you a real, hands-on project and challenge to complete. You can find [the original announcement post here](https://dev.to/forrestbrazeal/the-cloud-resume-challenge-503g).

In the last few episodes we wrapped up building out the front-end and front-end infrastructure (S3, CloudFront, Route53). Now we're moving onto the backend and getting a hit counter setup on our website to track the number of users who come to the site. 

In this last video, I go through how to break down an AWS Lambda function using AWS SAM. The purpose is so that we have two AWS Lambda functions, one is a GET, and one is a PUT that we'll be using for our API's and our resume hit counter. 

{% youtube xO0hKKkDjRk %}

If you're thinking getting into cloud I do really recommend you check out the cloud resume challenge as a place to start!

And we are already on our honeymoon!

Therefore I'm not going to make this long, I've thought about this hard and it's time to put in a break.

It's been 413 consecutive days of writing, and I think I deserve a small break.

Let's say we see each other again on the 15th, so you only have to miss my writing for 10 days.

From the bottom of my heart, I want to thank every single one of you for reading and sharing my articles.

See you soon,

Should we use databases as pure data storage without application logic?
Tags: help, database
Published: 2021-05-11 06:37:20

**Database with application logic:** includes views, triggers, procedures, etc
 
 
**Database without application logic:** tables/collections only

Personally, even if it can offload development time to the database, having application logic in the database has a lot of issues: difficult to maintain, difficult to version, having the business logic split into multiple parts of the application infrastructure.

When you keep all your application logic in the application code, everything is under control and easier to maintain over time.

Isn't it?
Decision making and looping
Tags: loops, clanguage
Published: 2021-05-11 06:35:01

A normal program is not a sequential execution of expressions or statements one after the other. It will have certain conditions to be checked or it will have certain number of iterations. 

When we have to execute particular set of instructions multiple times or known number of times (iterations), then we use FOR loops or DO/WHILE loops.


    If… Else Statements
    For Loops
    While and Do/While Loops
        The general syntax for while and do/while loops are given below :

# If… Else Statements

These are the decision making statements.  It is used for checking certain condition to decide which block of code to be executed.  syntax for if..else statement is

if (condition / s){
    expressions / statements;
} else {
    expressions / statements;
}

if (condition / s){
  expressions / statements;
} else if {
  expressions / statements;
} else {
  expressions / statements;
}

>example :
if (intDivisor == 0) {
  printf ("Warning!: Divisor is Zero!!\n Please re-enter the divisor :");
  scanf ("%d", &intDivisor);
}

intResult=intDividend / intDivisor;

If statement can have expressions to be executed when the condition is false. Those expressions are added in the else part of the ‘if’ statement.

if (condition / s) {
  expressions / statements;
} else {
  expressions / statements;
}

>Example :
if (intVal >= 0)
  printf ("You entered a Positive Number!");
else
  printf ("You entered a Negative Number!");


We can have if statement within another if statement, i.e.; we can have nested if statements.
e.g.: –
if (intVal >= 0)
  if (intVal == 0)
    printf ("You entered a Zero!");
  else
    printf ("You entered a Positive Number!");
else
  printf ("You entered a Negative Number!");

# For Loops:
A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.

Syntax:

for (intial_value; condition; increment_factor) {
    statement/s;
  }
>Example:
 
void main () {
  int intNum; 
  printf ("\n First 15 natural numbers are: \n");
  for (intNum = 0; intNum < 15; intNum++) {
    printf ("%d  ", intNum);
  }
}

# While loop: 
A while loop in C programming repeatedly executes a target statement as long as a given condition is true.
Syntax:
while (condition/s){
    Expression / statements;
}
>Example:
 
void main() {
  int intNum = 0;
  printf("\n Example of WHILE Loop\n");
  printf("First 15 natural numbers are: \n");
  while (intNum < 15){
    printf("%d  ", intNum);
    intNum++;

# Do/While Loops:
The body of do...while loop is executed once. · If the test expression is true, the body of the loop is executed again and the test expression is evaluated
Syntax:

do{
  Expression / statements;
} while (condition/s);

>Example:
{
  printf("\n Example of DO/WHILE Loop\n");
  printf("First 15 natural numbers in descending order is: \n");
  while (intNum >=0){
    printf("%d  ", intNum--);
 
}
How Bulk SMS Technology Works
Tags: bulksms, smsgateway, masssms, textsms
Published: 2021-05-11 06:22:38

The phone is the easiest and most effective way to reach your customers. Since individual calls can get expensive, bulk SMS Dubai is a cheaper and more efficient way to keep in touch with your customers. Bulk SMS is especially useful when you want to keep your customers informed about product updates, announcements, and new releases.

![Bulk SMS](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/5vnkg3jeo2wbymo78t9a.jpg)

Bulk SMS relies on modern technology and can be used with little human intervention. That makes it very efficient. A server using an application programming interface (API) or a desktop using a web SMS interface can be used to send bulk SMS.

<b>API vs Web SMS</b>
An API is available as HTTP (Hypertext Transfer Protocol) or HTTPS (HTTP Secure) and connects a website or application to an SMS gateway. SMS gateways are telecommunication channels that are used to send and receive SMS (Short Message Service).

Web browsers facilitate web SMS services. Web SMS users prefer to receive "long numbers", which are essentially the end-user's phone numbers, rather than the "shortcode" option. The latter is also more expensive.

Regardless of the interface, the bulk SMS gateway service is highly specialized and in high demand and has tools to help you track the status and generate reports.

The delivery rate of bulk SMS depends on several factors, but most importantly on the protocol used by the bulk SMS gateway provider.

<b>SMPP or SMTP</b>
Peer-to-peer, or SMPP, short messages are the most reliable method of sending bulk messages. Usually, the network of the mobile operator is used to deliver the messages to phones. Simply put, it uses the same technology that we use to send messages from one phone to another. Because of this, it is also more expensive than SMTP or Simple Mail Transfer Protocol.

SMTP is used to send an email and can also be used to send text messages, although it is not specifically intended for that purpose. However, when a text message is routed over SMTP, there is no guarantee that the message will be delivered or how it will appear on the customer's phone. And although there are statistics on tracking the <a href="https://smsala.com/bulk-sms">bulk SMS</a>, it is not possible to determine with certainty whether the SMS was delivered in the intended form. This is exactly why bulk SMS gateway providers using the SMTP protocol are much cheaper than those using SMPP. SMPP is more expensive because it pays to use the carrier's network for every SMS sent with it.
