What Is a Docker Base Image? A Docker base image is the foundational layer from which containers are built. Think of it as the starting point for your applications environment. Its a minimal, preconfigured template containing an operating system, runtime tools, libraries, and dependencies. When you write a Dockerfile, the FROM command defines this base image, setting the stage for all subsequent layers.

AI Flame Graphs are now open source and include Intel Battlemage GPU support, which means it can also generate full-stack GPU flame graphs for providing new insights into gaming performance, especially when coupled with FlameScope (an older open source project of mine). Here's an example of GZDoom, and I'll start with flame scopes for both CPU and GPU utilization, with details annotated: (Here are the raw CPU and GPU versions.

When you are serving millions of users, resilience cannot be something you add later. It has to be part of the design from the very beginning. Otherwise, with the way user expectations keep climbing and how global traffic patterns shift, your system simply wont keep up. What I want to walk you through today is how top companies think about resilience at scale.

Information technology continues to transform at an accelerated pace because modern businesses seek faster, high-performance applications. JavaScript-based development solutions from the past tend to fall behind when performing complex computations, which produce performance issues along with ineffective execution. Fast, efficient web applications emerge through a synergistic relationship between Rust and Wasm technology.

If you’ve tried running MongoDB on Kubernetes, you’ve likely run into some unique challenges. Stateful workloads like replica sets and sharded clusters can be messy in containers, and things that should be easy, like backups, scaling, failovers, and upgrades, suddenly take more time and attention than they should.

MongoDB Atlas and ScaleGrid for MongoDB offer two distinct approaches to running MongoDB in the cloud. Both support high-performance, data-driven applications but which one fits your use case best? While MongoDB Atlas delivers a fully managed experience tied closely to MongoDB’s ecosystem, ScaleGrid mostly matches Atlas capabilities while also being attractive for organizations with complex deployment needs, strict compliance requirements, or those optimizing for performance and budget.

For many reasonsincluding scalability, flexibility, and modernizationmore and more development teams are looking to migrate away from PostgreSQL to MongoDB. In the past, these teams might have been hesitant if they used Entity Framework Core (EF Core) as their object relational mapper (ORM). With EF Core being one of the most popular ORMs for.NET development, we received a lot of requests from the community for a provider, and so did Microsoft!

User experience is king in the crowd-sourced world of mobile app development, especially in the case of speed. If your app takes too long to load, those same users will bypass your app in favour of a speedy, seamless offering. When we realized that our app was taking a frustrating 8 seconds to load some screens, this was a hard reality for us to accept.

Most companies find that the biggest challenge to AI is taking a promising experiment, demo, or proof-of-concept and bringing it to market. McKinsey Digital Analyst Rodney Zemmel sums this up: Its so easy to fire up a pilot that you can get stuck in this death by 1,000 pilots approach. Its easy to see AIs potential, come up with some ideas, and spin up dozens (if not thousands) of pilot projects.

Application and system designs have always been considered the most essential step in application development. All the later steps and technologies to be used depend on how the system has been designed. If you are a Java developer, choosing the right approach can mean distinguishing between a rigid, complex schema and a nimble, scalable solution. If you are a Java developer who works with PostgreSQL or other relational databases, you understand the pain of representing the many-to-many relations

Core dumps play a key roll role in debugging programs that exit abnormally. They preserve a state of a program at failure, and with them, programmers can view and identify causes of failures. In this article, a walkthrough is taken through a step-by-step exercise of enabling, creating, and checking out core dumps in Linux and touches on high-end tools and techniques for debugging sophisticated failures, and enables quick diagnoses and resolution. 1.

Consulting is an episodic line of work. Thats great for the individual consultant because of the sheer variety it provides: different industries, companies, people, jobs and problems to solve. You get to see not only how many unique ways companies do similar things, but (if youre paying attention) youll understand why. Plus, every problem calls for different sets of knowledge and skills, meaning youll get the chance to learn as much as you already know.

Introduction to AWS Network Load Balancer AWS has several critical services that drive the internet. If you have ever built any application on top of AWS and need a high throughput or volume of traffic, the chances are that youve leaned on an AWS Network Load Balancer at some point in the discussion. AWS NLB is nothing but a Layer 4 load balancer, and consistency helps with low-latency forwarding of massive amounts of TCP, UDP, and even TLS traffic.
