High Performance tDiary
High Performance tDiaryHiroshi SHIBATA
?
The document discusses improvements made to the tDiary blogging engine to improve performance. Profiling with StackProf identified areas for optimization, including replacing the REXML XML parser with Oga for faster parsing, and improving the calendar generation method. Benchmarks show the changes led to a 4x speedup of the Amazon plugin and over 1.2x speedup of calendar generation. Loading plugins was also optimized by evaluating the code in a single pass rather than per file.node ffi

The presentation emphasizes how these modifications are implemented using hooks, bindings, tracepoints and other Ruby internals.Puppet Module Reusability - What I Learned from Shipping to the Forge
Puppet Module Reusability - What I Learned from Shipping to the ForgePuppet
?
A simple search for "puppet-apache" on GitHub returns 70 separate repositories. An awful lot of people are busy reinventing the same configuration wheel. Configuration management tools promise write once, run anywhere code; but writing code that can be used by anyone looks like a lot of work. This presentation aims to show anyone familiar with Puppet how to write reusable modules and importantly how to make them compatible with already shared modules released on the Forge or elsewhere. We'll look at when and why testing a declarative language is actually useful, examples of good and bad modules and how to re-factor puppet code for re-usability. We'll also talk about potential improvements to Puppet that would make reuse easier.

JavaScript Growing UpDavid Padbury
?
JavaScript is evolving with the addition of modules, platform consistency, and harmony features. Modules allow JavaScript code to be organized and avoid naming collisions.

Java Apps on AWS Without the Headaches: Fast Builds, Cheap Deploys, No Kubernetes
Let¡¯s face it: the cloud has gotten out of hand. What used to be simple¡ªdeploying your Java app¡ªhas become a maze of slow builds, tedious deploys, and eye-watering AWS bills. But here¡¯s the thing: it doesn¡¯t have to be this way. Every minute you spend waiting on builds or wrestling with unnecessary cloud complexity is a minute you¡¯re not building the features your customers actually care about.
In this talk, I¡¯ll show you how to go from a shiny new Java app to production in under 10 minutes¡ªwith fast builds, cheap deploys, and zero downtime. We¡¯ll go deep into optimizing builds with Gradle (it¡¯s time to leave Maven in the dust), parallelization strategies, and smarter caching mechanics that make your CI/CD pipelines fly. From there, we¡¯ll review the dozen+ ways AWS lets you deploy apps and cut through the chaos to find the solutions that work best for lean, fast, cost-effective pipelines. Spoiler: ECS and EKS usually aren¡¯t the answer. Oh, and I¡¯ll even show you how AI tools like AWS Bedrock can help streamline your processes further, so you can automate what should already be automatic.
This talk is for developers fed up with the cost, complexity, and friction of modern cloud setups¡ªor those who long for the simplicity of the Heroku/Beanstalk/PCF days when deploying to the cloud wasn¡¯t a headache. Whether you¡¯re on AWS, Azure, or GCP, you¡¯ll learn actionable, cloud-agnostic tips to build faster, deploy cheaper, and refocus on what matters most: delivering value to your users.Smarter RAG Pipelines: Scaling Search with Milvus and Feast

How Telemedicine App Development is Revolutionizing Virtual Care.pptxDash Technologies Inc
?
Telemedicine app development builds software for remote doctor consultations and patient check-ups. These apps bridge healthcare professionals with patients via video calls, secure messages, and interactive interfaces. That helps practitioners to provide care without immediate face-to-face interactions; hence, simplifying access to medical care. Telemedicine applications also manage appointment scheduling, e-prescribing, and sending reminders.
Telemedicine apps do not only conduct remote consultations. They also integrate with entire healthcare platforms, such as patient forums, insurance claims processing, and providing medical information libraries. Remote patient monitoring enables providers to keep track of patients' vital signs. This helps them intervene and provide care whenever necessary. Telehealth app development eliminates geographical boundaries and facilitates easier communication.
In this blog, we will explore its market growth, essential features, and benefits for both patients and providers. All-Data, Any-AI Integration: FME & Amazon Bedrock in the Real-World

Automated Engineering of Domain-Specific Metamorphic Testing EnvironmentsPablo G¨®mez Abajo
?
Context. Testing is essential to improve the correctness of software systems. Metamorphic testing (MT) is an approach especially suited when the system under test lacks oracles, or they are expensive to compute. However, building an MT environment for a particular domain (e.g., cloud simulation, model transformation, machine learning) requires substantial effort.
Objective. Our goal is to facilitate the construction of MT environments for specific domains.
Method. We propose a model-driven engineering approach to automate the construction of MT environments. Starting from a meta-model capturing the domain concepts, and a description of the domain execution environment, our approach produces an MT environment featuring comprehensive support for the MT process. This includes the definition of domain-specific metamorphic relations, their evaluation, detailed reporting of the testing results, and the automated search-based generation of follow-up test cases.
Results. Our method is supported by an extensible platform for Eclipse, called Gotten. We demonstrate its effectiveness by creating an MT environment for simulation-based testing of data centres and comparing with existing tools; its suitability to conduct MT processes by replicating previous experiments; and its generality by building another MT environment for video streaming APIs.
Conclusion. Gotten is the first platform targeted at reducing the development effort of domain-specific MT environments. The environments created with Gotten facilitate the specification of metamorphic relations, their evaluation, and the generation of new test cases.SAP Automation with UiPath: SAP Test Automation - Part 5 of 8
