Elixir v1.14 shipped earlier this month with a bunch of new goodies. In this post, we'll explore Elixir's new PartitionSupervisor. We'll take a look at some code that suffers from the exact bottleneck issue that partitions supervisors are designed to solve. Then, we'll fix that bottleneck. Along the way, you'll learn how partition supervisors work under the hood to prevent process bottlenecks. Let's get started!

Product retention is an extremely important metric to check the health of your business. Calculating the retention rate of your business will return the percentage of users who continue using your product or service over a given time period. Retention can really be seen as a gauge for customer loyalty and a good reflection of the quality of your customer relationship with a new or existing customer.

Is it enough? The data we consume in our homes and businesses continues to grow at a blistering pace. Internet of Things (IoT) device connections are also increasing exponentially, with the average number of devices per connected home more than doubling just over the past couple of years. To address all of this growth, service providers are continuously expanding their fiber to the premise (FTTP) and hybrid fiber-coax (HFC) footprint.

A website's responsiveness is very significant these days in order to display correctly on all devices. Although you may try your best, broken layouts may still occur despite your best efforts. Long words can be broken and wrapped to the next line when you use the CSS word-wrap property. A string being too long can overflow a container in most cases, so this method can be helpful in preventing overflow.

Want to deploy a Rails app with Docker and AWS, but not sure where to start? AWS Fargate simplifies the convoluted process of deploying Docker on Amazon's Elastic Container Service (ECS). It's also a good alternative to Heroku.

UI is nothing without UX. While user interface development is essential, it means nothing if it doesn’t lead to a good user experience. So whenever us devs add a new feature, or modifies the existing one, we must ensure the UX flows seamlessly. And that means thorough testing. Generally, the development process should involve tests at both the module and unit level to ensure both work as expected through the changes.

Processes are the heart of every organization and every workflow. But if yours are a bit of a mess, you’re not alone. Businesses everywhere are struggling with inefficiency and just can’t seem to digitize workflows fast enough. And when they do, it’s hard to tell if they've even improved the problems they set out to solve in the first place. . . or just created more chaos.

Value Stream Management (VSM) is about empowering delivery organizations to measure, mitigate, and monitor complexity. Simply put, it aims at improving the flow of value in your organisation. The VSM Consortium recently released their highly anticipated report on “The State of Value Stream Management 2022” . In this post we recap some of the findings and look at it specifically from a software engineering and platform engineering point of view.
