Django is well known for being used to develop servers for HTTP connections and requests for applications. Unfortunately, when building Django chat app or any chat app that requires the connection to remain open for a two-way connection, using an HTTP connection is inefficient.

WebSockets provide a means of opening a two-way connection between the client and the server so that all users connected to the open network can get related data in real time. It is a stateful protocol, which means connection authentication is only required once; the client credential is stored, and there is no further need for authentication until the connection is lost.

In this article, I’ll briefly introduce you to WebSocket and its usefulness. Then, I’ll show you how to use it in Django using Django channels and create WebSocket connections with JavaScript to connect with the Django server.

We will build a simple chatbox to make things more realistic. You can find the code on GitHub.

Building stateful web applications can be tricky, unless you use a framework, of course. Django to the rescue! In this article, learn how to build a Djano chat...

In this tutorial, we'll look at how to integrate Django REST Framework (DRF) with Elasticsearch. We'll use Django to model our data and DRF to serialize and serve it. Finally, we'll index the data with Elasticsearch and make it searchable.
What is Elasticsearch?

Elasticsearch is a distributed, free and open search and analytics engine for all types of data, including textual, numerical, geospatial, structured, and unstructured. It's known for its simple RESTful APIs, distributed nature, speed, and scalability. Elasticsearch is the central component of the Elastic Stack (also known as the ELK Stack), a set of free and open tools for data ingestion, enrichment, storage, analysis, and visualization.

Its use cases include:

Site search and application search
Monitoring and visualizing your system metrics
Security and business analytics
Logging and log analysis

This tutorial looks at how to integrate Django REST Framework with Elasticsearch.

You’re about to read a blog post with a lot of advice. Learning from those who came before us is instrumental to success, but we often forget an important caveat. Almost all advice is contextual, yet it is rarely delivered with any context.

“You just need to charge more!” says the company who has been in business for 20 years and spent years charging “too little” to gain customers and become successful.

“You need to build everything as microservices!” says the company who built a quick monolith, gained thousands of customers, and then pivoted into microservices as they started running into scaling issues.

Without understanding the context, the advice is meaningless, or even worse, harmful. If those folks had followed their own advice early on, they themselves would likely have suffered from it. It is hard to escape this trap. We may be the culmination of our experiences, but we view them through the lens of the present.

So to give you a little context on where my advice comes from, I spent the first half of my career as a software engineer working for various small businesses and startups, then I went into consulting and worked in a number of really large businesses. Then I started Simple Thread and we grew from a team of 2 to a team of 25. 10 years ago we worked with mostly small/medium businesses, and now we work with a mix of big and small businesses.

My advice is from someone who…

has almost always been on small, lean teams where we have to do a lot with very little.
values working software over specific tools.
is starting new projects all the time, but also has to maintain a number of systems.
values engineer productivity over most other considerations

My experiences over the last 20 years have shaped how I view software, and have led me to some beliefs which I’ve tried to whittle down to a manageable list that I hope you find valuable.

Important, Read This First You’re about to read a blog post with a lot of advice. Learning from those who came before us is instrumental to success, but we often forget an important caveat.

In their review, TechpowerUp shows the AMD Ryzen 7 7800X3D sitting ahead of all other 3D V-cache CPUs and Intel's flagship Core i9-13900K across all resolutions (1080p/1440p/2160p) on average. The CPU also delivers the fastest minimum FPS across an average of several AAA titles however we have to get to the power numbers because those are simply brutal against Intel's i9-13900K.

Reviews of the AMD Ryzen 7 7800X3D CPU, the much-awaited 3D V-Cache chip, have landed and show insane efficiency in gaming performance.

New performence improvements in Python 3.11

Python 3.11 was released a few days ago and as usual, it comes with more than a few new features that make it ever more interesting, from exception groups and fine-grained error locations and tracebacks to TOML parsing support in the standard library and of course the much awaited speedup as part of...

Heroku is a mature, battle-tested, and stable platform. It does a lot of heavy lifting for you and will save you a lot of time and money, especially for small teams. Heroku allows you to focus on your product instead of fiddling with your server's configuration options and hiring a DevOps engineer or SysAdmin.

It may not be the cheapest option, but it's still one of the best PaaS on the market. Because of that, if you're already using Heroku, you should have a strong reason to move away from it.

While there are a number of alternatives on the market, none of them match Heroku's developer experience. At the moment the most promising alternatives to Heroku are DigitalOcean App Platform and Render. The problem with these two platforms is that they are relatively new and not (yet) battle-tested. If you're just looking for a place to host your apps for free, go with Render.

In this article, you'll learn what the best Heroku alternatives (and their pros and cons) are.

Samsung's new second-generation computational SSD can process data without needing other devices. The new device allows data transmission between several elements involved in the computed pathways.

A benefit of processing data on the SSD is that users will not need to transfer information between several storage devices. The new computational SSD allows bandwidth to make streams faster, lowering data latency since fewer unnecessary packages travel between the storage device and the processor. And in turn, the processor is allowed to focus on more tasks, especially those that are more critical to the system.

Samsung introduces AMD-Powered Computational SSD to help improve data throughput between the SSD and CPU for supercomputers.

AMD's EPYC Genoa CPUs are going to offer some insane performance increase for the x86 server segment as we witnessed in the leaked benchmarks a few days ago and now, we get to see an even better performance teaser in the form of the cache and latency benchmarks for the top EPYC 9654 CPU which rocks up to 96 cores and completely shatters the AMD Milan-X CPUs with its huge inter-cache bandwidth figures.

AMD's EPYC 9654 "Genoa" 96 Core CPU has been tested in Cache & Latency benchmarks and tears apart Milan-X and Sapphire Rapids server chips.
