GPUs Public Preview: Run AI workloads on H100, A100, L40S, and more

Welcome to day two of Koyeb launch week. Today we're announcing not one, but two major pieces of news: Our lineup ranges from 20GB to 80GB of vRAM with A100 and H100 cards. You can now run high-precision calculations with FP64 instructions support and a gigantic 2TB/s of bandwidth on the H100. With prices ranging from $0.50/hr to $3.30/hr and always billed by the second, you'll be able to run training, fine-tuning, and inference workloads with a card adapted to your needs.

A guide to PHP attributes

When building web applications in PHP, there may be times when you want to add metadata to annotate your code that can be read by other parts of your application. For example, if you've ever used PHPUnit to write tests for your PHP code, you'll have likely used the @test annotation to mark a method as a test in a DocBlock. Traditionally, annotations like this have been added to code using DocBlocks. However, as of PHP 8.0, you can use attributes instead to annotate your code in a more structured way.

Database generated events: LiveSync's database connector vs CDC

Ably LiveSync is a product we launched last month to help developers deliver live updates in their applications by automatically keeping their database and frontend clients in sync. LiveSync is made of two components, the Models SDK that runs on the client, and the database connector that listens to changes in your database and syncs those changes to your clients.

Resque v Sidekiq for Ruby Background Jobs Processing

Background job processing is integral to modern software architecture. Background jobs allow resource-intensive tasks to be handled asynchronously, improving your application’s responsiveness and efficiency. You can use background processing for tasks such as sending emails, data processing, and batch jobs. If you were to run these synchronously, they could significantly degrade the user experience and system performance. Thus, most frameworks have libraries for running background jobs.

Spreadsheets vs. Test Management Tools: Unleash the Power of Efficient Test Cases

In the ever-evolving world of software development, a well-defined test plan is the cornerstone of a successful Quality Assurance (QA) process. For QA professionals, testers, testers, and developers alike, a robust plan ensures comprehensive testing, minimizes risks, and ultimately delivers high-quality software. Traditionally, spreadsheets like Excel have been the go-to tool for crafting test plans. However, as projects grow in complexity, the limitations of spreadsheets become increasingly apparent.

What is a Headless Data Architecture?

The headless data architecture. Is it a fad? Some marketecture? Or something real? In this video, Adam Bellemare takes you through the basics of the headless data architecture and why it’s beginning to emerge as its own respective pattern. Driven by the decoupling of data computation from storage, the headless data architecture provides the basis for a modular data ecosystem. Stream your data for near real-time low latency use cases, or convert it to an Iceberg table for analytical use cases.

New in PHP 8.4: engine optimization of sprintf() to string interpolation

PHPs compiler and bytecode cache OPcache not only cache the compile step from PHP source code to virtual machine bytecode, they also include optimizations that can produce faster bytecode: For example PHP can: For PHP 8.4 Tideways sponsored the work of our colleague Tim to add another compiler optimization for the function sprintf().
