TL;DR Hack - add as a library in IntelliJ project. Tactic - add as system scope in maven. Tactic/Strategic - install locally to .m2. Strategic - use a repository management tool, publish to maven central Sometimes you want to work with a jar file that isn't hosted in maven central. It might be a 3rd party jar, it might be one that you have written. Regardless. You have a lot of options for this. The approaches that I have used: - add .jar files as an IntelliJ project dependency - install it locally to your .m2 repository - add it to your project as a system scoped file - use a repository management tool like Nexus or Archiva - publish the dependency to maven central

It's hard to imagine a modern developer workflow without a sufficiently advanced build system: Make, Gradle, Maven, Rake, and many others. In this talk, we'll discuss the evolution of build systems that leads to distributed build systems. Then, we'll dive into how we can build a scalable system that is fast and resilient, with examples from Google. We'll conclude with the discussion of general challenges of migrating systems from one architecture to another.

Learn how to scale your Continuous Integration and Continuous Delivery environment using containers. The Kubernetes project provides a container orchestration solution that greatly simplifies app deployments in large clusters and you can use Jenkins and Kubernetes together to run jobs on-demand. Building and testing is a great use case for containers, both due to the dynamic and isolation aspects, but it increases complexity when scaling to multiple nodes and clusters. Jenkins is an example of an application that can take advantage of Kubernetes technology to run Continuous Integration and Continuous Delivery workloads. Jenkins and Kubernetes can be integrated to transparently use on demand containers to run build agents and jobs, and isolate job execution. It also supports CI/CD-as-code using Jenkins Pipelines and automated deployments to Kubernetes clusters. The presentation will allow a better understanding of how to use Jenkins on Kubernetes for container based, totally dynamic, large scale CI and CD.

Video here: http://bit.ly/oww-mesoscon2015-video The promise of Mesos to create a datacenter-centric resource pool is a great idea. However, a decade old company with many different types of existing systems and unique workloads can't simply mass migrate to Mesos. That doesn't mean Mesos can't pay a huge part in unifying disparate workloads that construct existing systems while opening the door to new Mesos-centric development. In this presentation, Steve will cover 3 very different use cases that are being unified under Apache Mesos including: Automated builds of existing code artifacts, automated builds of AWS AMIs via packer in EC2, and rolling deploys & supervision of Docker microservices across environments. The addition of Docker on Mesos has enabled this, but that doesn't mean that all Mesos slaves should be identical. See how the addition of localized support services on slaves can compliment your Docker on Mesos use cases.

microXchg 2019, Berlin: Talk by Mario-Leander Reimer (@LeanderReimer, Principal Software Architect at QAware) === Please download slides if blurred! === Abstract: Only a few years ago the move towards microservice architecture was the first big disruption in software engineering: instead of running monoliths, systems were now build, composed and run as autonomous services. But this came at the price of added development and infrastructure complexity. Serverless and FaaS seem to be the next disruption, they are the logical evolution trying to address some of the inherent technology complexity we are currently faced when building cloud native apps. FaaS frameworks are currently popping up like mushrooms: Knative, Kubeless, OpenFn, Fission, OpenFaas or Open Whisk are just a few to name. But which one of these is safe to pick and use in your next project? Let's find out. This session will start off by briefly explaining the essence of Serverless application architecture. We will then define a criteria catalog for FaaS frameworks and continue by comparing and showcasing the most promising ones.

ADR, or Architecture Decision Record, is a valuable tool in software development for several reasons. It provides a centralized location for documenting and tracking architectural decisions, aiding both current and future team members. ADRs enhance communication among team members by documenting the rationale behind architectural decisions, especially beneficial during onboarding of new team members or when revisiting decisions. They serve as a knowledge base, enabling teams to learn from past decisions and refine their decision-making process. Additionally, ADRs contribute to transparency by helping stakeholders understand the reasons behind specific architectural choices. As with any other tool or process, introducing them into an organization can face several obstacles, and overcoming these challenges is crucial for successful implementation. In this talk I go through some common problems and our way of solving them.

Data spaces in distributed environments should be allowed to evolve in agile ways providing data space owners with large flexibility about which data they store. Agility and heterogeneity, however, jeopardize data exchanges because representations may build on varying ontologies and data consumers may not rely on the semantic correctness of their queries in the context of semantically heterogeneous, evolving data spaces. Graph data spaces are one example of a powerful model for representing and querying data whose semantics may change over time. To assert and enforce conditions on individual graph data spaces, shape languages (e.g SHACL) have been developed. We investigate the question of how querying and programming can be guarded by reasoning over SHACL constraints in a distributed setting and we sketch a picture of how a future landscape based on semantically heterogeneous data spaces might look like.

We perform this come-to-me love spell that works instantly with the aim of bringing back the victim to the person performing the magic. Have you lost your lover? Do u need to solve any relationship problem? Contact the powerful spells caster chief kule with love spells that work overnight and love spells that really work. Have you found yourself infatuated with a special someone you think could be the one? Are you looking for a spell to provide them with a nudge in the right direction? Or maybe the spell you cast didn’t achieve the results you were hoping for? Whether you’re new or versed in the ways of spell casting, we’re here to help. Today we’re going to provide you with a detailed guide on the types of love spells to cast. Not only that but there’s something for those who wish to find outside advice from more advanced spell casters. We’re also going to provide you with the top sites available to help you with your dilemma. Let’s begin our journey by educating ourselves on love magic and what a real love caster looks like. Love Magic and Love Casters Love magic made its first appearance back in Ancient Egypt and has been an active practice since. This type of magic is a branch of traditional magic and can be practiced in various ways. Typically the more common use of love magic is through the work of spells, but other methods look like Charms Rituals-LOVE Potions-Dolls and even Amulets If you are interested in becoming a love caster, be prepared for what’s to come. A genuine love caster knows that the art of love casting is no easy feat and shouldn’t be done casually. You should know that not only does it require you to be gifted spiritually, but you must be ready to serve others. Someone who is considered a real love caster has experience in all manner of spells, no matter the difficulty. Training yourself in attraction, commitment, and marriage spells is an excellent place to start. But this by no means will make you a professional. Practice your craft and expand your knowledge; understand that you will possess the ability to help others in time truly. Types of Love Spells What better way to start broadening your experiences with love spells than by learning more about them? These spells work like just about any other spell. Simply apply your intention, use a medium (sigils, mantras, candles, or charm bags), and top it off with establishing the belief that you will receive what you want. So what kind of spells are available and which ones suit your needs the best? Let’s take a look at the many options you have at your disposal.
