Stop me if you have heard queries like these before: Why am I using {Product X} to build a {Task Y} website? Why am I rebuilding {Product X} to act like {Product Y}? Why can’t this {organizational asset} be flexible for {Product Y} instead of just {Product X}? Questions like these highlight an issue we face more in our day-to-day work in the ever-evolving web: content management system tunnel vision. Sometimes, our organization gets fixated on a particular platform or content management system, even when alternatives and successors exist. And over time, this stagnation hinders growth, expansion, trends, technologies, and eventually even adoption. In this presentation, I will cover the value of creating a web system ecosystem in your institution, department, unit, or organization. I'll cover: On-Campus CMS Usage Today - Discussion on scenarios where a CMS is being reconfigured to meet a demand it wasn’t meant to do, and the fallout from said reconfiguration. Why this approach is expensive in the long haul. What is a Web CMS Ecosytem? - Discussion on a different look at a system, where CMSs are provisioned and recommended for uses and have affordances and tradeoffs. Change the Community Mindset - Let’s consider the growth, explosion, and fall of CMS systems and stay on top of trends, platforms, and best-practices. Exploring Ecosystem Adoption- Discussion on changing mindsets, running pilot studies, experimentation, exploration, and research to determine organizational web makeup, goals, needs, and expectations. Angle Your Institutional Assets - Discussion on side-effects of this move, which may include CMS-agnostic branding and style guides, flexible and scalable plugins and campus application integrations for each system, and pain-minimized migration paths between services and applications.

Perhaps one of the perplexing things about cloud computing is the choice around renting time in someone else’s cloud (Amazon, Google, Rackspace or a myriad of others) or building your own. It’s not unlike the age-old car buyer’s dilemma, take the lower payments and lower total miles lease or buy the car and drive it for the long haul. Cloud computing users are often faced with the same conundrum. This presentation will focus on how to buy and build a cloud that can be fulfill the needs of most users including strategies for making use of the open source private cloud or managing workloads in both the private and public cloud using open source software.

More and more startups/companies are deploying their infrastructure directly and exclusively in EC2 or similar cloud provider. With that comes a whole new set of challenges and paradigms around scalability, reliability and availability. This talk will focus on how to leverage all the infrastructure parts of AWS, augment them with great (affordable) third party services and solid Open Source Software to create an operations environment that will scale with you, be as reliable as it can be, providing you and your peers with all the data you need to make good decisions to support (rapid) changes while letting you sleep through the night. And all that using a tiny operations team. It may make you coffee in the morning too.

Why are migrations important? This session will discuss how to put your databases on version control. The presentation is based on the assumption that the developer already knows about version control and is using it on their projects in some form. L-Migrator will be discussed in relation to its integration into PageBlocks and its stand alone use. Attendees will come away with a knowledge of the methodology behind migrations, why they are important and when to use them, as well as shortcuts and tips for writing Lasso Migrations and the dangers of performing destructive migrations.

Do you have a monolith? If so, is it majestic? Or is it broken and preventing you from scaling your application and your business? Monoliths have earned a bad reputation in software architecture design circles for being difficult to maintain and operating on silos of knowledge. However, they aren't all bad. The key is knowing when to use a monolith, and when it is time re-factor and scale up by going small.

Beware the monolith

Ever thought about taking your infrastructure or platform team from a cosy group to premier league status? Let’s have a relaxed chat about making it big while staying on point. I dive into tales and tactics for beefing up your infrastructure from supporting fewer than 100 folks to powering a crowd of a thousand or more, all while keeping your tech solid and your team atmosphere upbeat. This session is perfect for leaders on the growth path and any tech pro involved in building or running infrastructure who’s aiming higher. Expect a down-to-earth rundown of dos and don’ts plus a handful of “oh no” moments from my journey of upsizing infrastructure at Spotify and beyond

Microformats allow you to extend the limited semantics of HTML, thus allowing for a richer web of data. By embedding microformats into HTML it is possible to use the semantic meaning to extract unambiguous data from the web that can then be used in other applications. Microformats focus on how people are already publishing their data online. This session focuses on the more technical aspects of microformats, how they interact with other Semantic Web technologies such as GRDDL and SPARQL, along with a look at browser plugins to detect microformats and browser integration.

Are you depressed? 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? 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.

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.
