Blogging with Django : Handle images media
Tags: webdev, tutorial, django, python
Published: 2023-01-20 06:45:34


Images are a vital part of any website or application. Without them, things would be pretty boring. In Django, images are handled a bit differently than other files. Here's everything you need to know about working with images in Django.

First, let's talk about how Django handles static files. Static files are files that are going to be used in our application that are not going to change. For example, CSS and JavaScript files are usually static. Images are also usually static. Django provides a utility for collecting static files from various apps into a single location. This is called the staticfiles app.

The staticfiles app has a few requirements. First, you need to have a directory in your project where all of your static files will be stored. This is called the STATIC_ROOT. Second, you need to tell Django where to find your static files by setting the STATICFILES_DIRS setting.

Once you have your static files configured, you can load them in your templates using the {% static %} template tag. This tag takes a path to a static file and returns the URL to that file. For example, if you have a static file at STATIC_ROOT/images/logo.png, you can load it in your template like this:

<img src="{% static 'images/logo.png' %}">

Now that you know how Django handles static files, let's talk about media files. Media files are files that are generated by our users. For example, user-uploaded images are media files. Django provides a utility for collecting and storing media files called the FileField.

The FileField is a model field that allows us to store files in our database. When a user uploads an image, the FileField will store it in our database. We can then access the image from our code using the ImageField.

let's say we have a model with a FileField called image:

class MyModel(models.Model):
    image = models.FileField(upload_to='images')

And we have an instance of MyModel called my_instance. We can access the image file like this:

my_instance.image.file

We can also access the URL of the image file like this:

my_instance.image.url

If you want to learn more about FileFields and ImageFields, check out the Django documentation.
3 Ways Of Assigning Variables in Go
Tags: go, programming, tutorial, webdev
Published: 2023-01-20 06:34:58

#### TABLE OF CONTENTS

1. [The Idiomatic Way](#the-idiomatic-way)

2. [The Short Way](#the-short-way)

3. [The Intuitive Way](#the-intuitive-way)

Go has become a go-to programming language lately. It's a statically typed language, meaning, it performs type checking at compile time. If I iron out the jargon, it simply means that the code is first compiled, like in C/C++ and then, it'll be ready for execution, unlike Python.  

The beauty of statically typed languages are that they try to be idiomatic or verbose as much as possible while defining or assigning values. It could be annoying for experienced developers, but it's good for beginners to know how things work in the background. 

A variable is a placeholder or a storage location, with a specific data type and an associated name. 

## The Idiomatic Way

```Go
package main

import "fmt"

func main(){

var greet string = "Hello Dev"

fmt.Println(greet)

}
```
Variables in Go are created by first using the _var_ **keyword**, then specifying the **variable name** _greet_ followed by the **type** _string,_ as we see from the above code (line 4).

In variables, _=_ symbol doesn't mean _is equal to_, unlike in Algebra. The right way to read that is, “greet is **assigned** to the string Hello Dev” or “greet takes the string Hello Dev”.

As the name (variable) suggests, the variables can change their value throughout their lifecycle of a program.

```Go
package main

import "fmt"

func main(){

var greet string = "Hello Dev"

fmt.Println(greet)

greet = "Welcome Dev"

fmt.Println(greet)

}
```
If we execute the above code, we'll get the following result.

![Code execution in Go](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ngsil9jmekfuyp7ihup5.png)

So the variable _greet_ has assigned to a new value _Welcome Dev_. Here's a caveat, we don't need to declare _var greet string_ again to reassign a different value. If we do so, we'll get an error message saying _greet redeclared in this block_.

Also remember, assigning a value at the start is optional, so we could use two statements as follows.

```Go
package main

import "fmt"

func main(){

var greet string 

greet = "Hello Dev"

fmt.Println(greet)

}
```
## The Short Way

Instead of using _var greet string_ or _var greet string = "Hello Dev”_, we can simply use **greet _:=_ "Hello Dev”**.

And there is no need to specify _type_ because Go compiler will infer the type based on the literal value. For example, the words between quotes as “strings” and any number like 1 as int.

## The Intuitive Way

Like _greet := "Hello Dev”_, we can also assign variables like **var greet = "Hello Dev”**. Hope these things make sense now. 

As you become proficient in Go, it's more likely that you use **:=** to assign values to a variable. 

That's all for today, hope this post helped you to clear some doubts about variables in Go, if it did, I would like to know your opinion, please write down your views in the comments.

Security Aspects for cloud adoption - Before Migration
Tags: beginners, aws, migration, security
Published: 2023-01-20 06:30:24

Hello Everyone, In continuation to my previous blog about the security, in this blog what all aspects should be kept in mind while planning for cloud adoption and before migration what all things should be kept in mind while selecting the cloud service provider. Since we already aware that security plays very important role for cloud adoption and very carefully we need to work on the security architecture to meet the current customer requirements.
Mostly when we plan to adopt the cloud there are various business drivers as well, so mostly it will like offering services to end customers or users and infrastructure is being opened to internet and when infrastructure is exposed over internet, security comes into picture and carefully we have plan the security framework to prevent the attacks like DoS, DDoS etc.
So moving forward one should have very clear picture about the current security picture of the customer environment and how to meet those customer requirements to adopt the cloud.
To meet the customer requirements, one can think on below points to plan how we can select the relevant cloud service provider:
1. Will the target cloud service provider able to meet the compliance requirements.
2. How much cloud service provider is flexible with customizations in security requirements.
3. How much automations are possible in the cloud security?
4. What kind of support we can get from cloud service provider to meet the modern day cloud security challenges.
5. Who are the security vendors that are providing support to cloud service provider.
6. How much cloud service provider is innovative in security framework in introducing new security features in the services.

This is not the complete list but covers pretty much how one can assess the cloud service provider.

I hope these guidelines will help you to enhance your knowledge.

Thanks for reading the blog.
The Philosophy Behind a Programming Language (Discussion)
Tags: discuss, programming, compiler, productivity
Published: 2023-01-20 06:24:43

This is not an educational post, it is a discussion. I am making a new programming language. The purpose is to make a surpassing general-purpose language that can solve most of the problems of the mainstream languages in the current generation. I have a belief, that **writing efficient code is the job of compilers, not the toil of programmers.** Programmers should only care about implementations of features, logic, and algorithm, not the syntax of the language. For example Rust, it sacrificed its programmers' development efficiency (borrow checking & lifetimes) in order to achieve generating a better and faster executable, of course without a garbage collector. (Perhaps this sounds offensive to Rust enthusiasts, my apology)
This language is in its planning phase. I wrote a document about the basics of the syntax and the "philosophy" behind it, and I deem that there must be numerous things that can be improved or corrected.

If you have any suggestions, please comment below or issue on GitHub (which is preferred) Hope you guys can write very detailed suggestions to me!

## The web is moving towards performance

When you look at the current web ecosystem, you'll see players like [Deno](https://deno.land), [Bun](https://bun.sh), [Qwik](https://qwik.builder.io) all pushing the frontier on performance in their own domain.

There is growing chatter in the development community regarding load times, content repaints, JS payloads etc. and though it's growing - not a lot of people care much for it.

Many developers, web agencies and / or frameworks still focus on product-first instead of overthinking optimizations.

## Speed is product, but there's a better way

It's no secret that [some sort of correlation](https://blog.hubspot.com/marketing/page-load-time-conversion-rates) exists between load times and conversions / sales and I think it's fair to argue that speed is a part of your product offering's KSP.

It's not always feasible to be performance-first focused when launching a new product or MVP of a product. This is where I think the [Kaizen](https://en.wikipedia.org/wiki/Kaizen) philosophy is a great tool.

Using the principles of *Continuous Improvement*, we can instead incrementally improve what matters. That is to say, we have a faster go-to-market and then we optimize.

## Sounds like a job for Auditio

[Auditio](https://auditio.cc) is a tool that provides us a way to do this. It allows you to add your website's URL and then set a frequency at which you want to run a Google Lighthouse audit on that URL. Just set, forget and check periodically.

Every day / week / month you are provided with a snapshot of your website's current performance. Using this we can implement the Kaizen philosophy and say: "We don't want 100% performance right now, but we want to at least know what we can do to be a little bit faster than yesterday or last week".

This approach, to me, seems much more sustainable than spending an exorbitant amount of time to optimize a site before it even goes to market to be validated in terms of utility and content.

## How fast should your website be?

I don't think a 100 score on every page is a healthy / realistic target, neither do I think 25 is great. To me the middle ground of improving what you can and maintaining what is good seems much better.

Let me know what your page ranks at! Do you think Auditio can be a useful tool?

> Note, right now there is a free offering at Auditio during their Beta stage. Check it out at https://auditio.cc.

Top 5 Reasons To Choose Java
Tags: java, javascript, react, mobile
Published: 2023-01-20 05:55:40

Java remains the most popular programming language for everything from [mobile development](https://www.infiraise.com/develop/mobile-app-development/) to business and server-side apps that support the middle tier. But do know the reasons to choose java?

## The Top 5 Reasons To Choose Java

### 1. Quick to Learn

Every programming language has a real challenge, but Java, C, C++, and JavaScript have a lot in common. Anyone who has worked with any of those languages will be able to easily pick up Java syntax.

### 2. Java in API

Its API has a lot of features. Over 200 built-in packages in the standard JDK include Java APIs for everything from parsing XML to converting across time zones. Developers that use the Jakarta EE APIs have access to an even larger set of APIs, allowing them to build complex middle-tier apps and cloud-native microservices.

### 3. Java ToolBox System

Software development tools created in Java — by [Java developers](https://www.infiraise.com/hire/hire-java-developer/) — abound in the application development environment, all aimed to make the creation, deployment, and even decommissioning of Java applications easier and faster. A few examples of tools are written below: 

- Gradle: an incredibly powerful, open-source build tool
- Maven: an open-source tool designed to solve dependency management problems
- Jenkins: a Java-based continuous integration and delivery tool

### 4. Fine Class Android Support

Android is the most popular mobile phone operating system in the world, and Java is the de-facto programming language for [Android app development](https://www.infiraise.com/develop/mobile-app-development/android-app-development/).

### 5. Great Evolutionary work

Java advances at a leisurely pace, but it does so. With almost 25 years of evolution under its belt, it has a long list of achievements to boast about.

Backward compatibility is just as crucial as adding new capabilities in [enterprise software development](https://www.infiraise.com/develop/enterprise-resource-planning/). For the language’s stewards, this has always been a key priority. Rarely does a major update or feature addition cause problems with code built for previous versions.

The Era of Big Companies
Tags: career, discuss
Published: 2023-01-20 05:20:04

It seems that the Era of big companies has finally ended this year.
With Dream companies like Microsoft, Google & Amazon starting mass layoffs and sources mentioning some of the impending targeted layoffs, we can no longer feel that even attempting to switch right now to these companies will be a good move.
Coming back to start-ups or product that are just being built seem more stable than these companies now-a-days and would perhaps be a better choice to move to.
