Micronaut, Dragon-Slayer (Spring/boot) or just another framework [GeeCON Krakow 2019]

•

0 likes•223 views

In the Java world, Spring is a great beast, a Dragon, and with a good reason. Spring is a very powerful framework which does a lot for developers while giving them a lot of power. All this power, of course, doesn't come without its price. Most of the developers using Spring are either happy to pay this price or not aware of it at all. On the other hand, Micronaut comes with the promise of all the power of Spring, while not having any of the costs that Spring brings to the table. Let us look at it, how it compare and differ to Spring and if it lives up to its promises.

Everyone who built any API encountered some questions, about design of API, sharing info about endpoints, what should be exposed and similar. Not a small number of us hit few limitations and problems along the way. All this problems and limitations of traditional REST API's are becoming more and more obvious with the move to distributed systems, Microsevices and working in large organizations with lot of teams across multiple countries and continents, who each build one part of big system. Join me in this talk, while I will show you some of the best practices that will help you to navigate this dangerous waters and also share how GraphQL can help you with some of them. After this talk you will understand why Facebook built and shared GraphQL with the world. All of this will be done through Java code, since code worth much more then only words

GraphQL vs Traditional Rest API [GeeCon Prague 2018]

Vladimir Dejanovic

What does GraphQL and Traditional REST API have in common? Shouldn't the GraphQL be connected to some graphs or similar? What is actually GraphQL all about? Join me in this talk, while I try to answer all this questions and much more. In this talk I will explain what GraphQL is, what are differences and similarities compared to more traditional REST API and show you this on working examples, since code worth more then words only ;) GitHub: https://github.com/vladimir-dejanovic/graphql-vs-traditional-rest-api-conftalk_demo

What Users Want, A/B testing explained [CodeteCon 2018]

Vladimir Dejanovic

We all would like to know what users want, right? Then we could build it and get a lot of money for it. But how to find out without being psychic, can we ask them ? The worst thing you can do is build the wrong thing. But how to know what is right and what is wrong? We don't have a crystal ball. Is our gut feeling the best we can do ? Join me while I take you on a trip behind the scene of some of the most successful website in the world. I will share their secret with you. How they made it happen, how they decide what to build, when to build and how to make sure that it is what the users want. And of course how they made their fortune in the process of doing this.

You heard of "new thing" called gRPC and promises that it will solve all issues for you, so now you are not sure if you should use it for breaking up your monolith to Microservices. If it is good for Google it should be good for you also right? On the other hand, you have been using REST API's for some time now, at least as a consumer, so maybe this would be better approach in Microservices waters, or would it? Which one to chose and which one will fit your use case better? Join me in this talk were I will try to explain both approaches, good and bad. I will give some points and tips, which will help you in understanding better which one will be better for you. By doing this I will also share some best practices for both approaches

What users want [DevoxxPL]

Vladimir Dejanovic

Vladimir Dejanović gave a presentation titled "What Users Want" at DevoxxPL on June 22, 2017. The document includes slides from the presentation discussing A/B testing methodology, including calculating expected values, the G-test statistic for measuring differences between measured and expected values, using the chi-squared probability test to calculate a P-value from the G-test, and determining statistical significance based on the P-value. Several references and examples are provided in the slides.

Changing wheels on moving car, from monolith to microservices by using api's V2

Vladimir Dejanovic

The document appears to be a presentation on transitioning from a monolithic architecture to microservices. Some key points discussed include: - The importance of using APIs to break up a monolith into independent services - Common mistakes made in this transition such as trying to achieve the "perfect" architecture or not using standards - Questions to consider when planning the transition, such as how to identify service boundaries and ensure high availability

Pain of growing up, and moving to large scale

Vladimir Dejanovic

You built your product, put it on server, and it flew like a rocket. Now you need to move to larger scale, but how ? How to go from here ? Deploying software isn't always the first thing on developers mind, while they work on some software. However as you start moving to larger scale your deployment process can make you or break you. It comes with pain and cruel truth of how good your deployment process really is. Join me while I address pain, issue and problems of deploying software on Large Scale. I will talk about some known approaches and their pro's and con's. Also I will share some tips and tricks into making deploying software on large scale easier. All of this come from my personal experience while working on this type of systems.

Protocol buffers and Microservices

Vladimir Dejanovic

Protocol buffers are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data – think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages. Join me in this talk to hear about first hand experience from building Microservices with Protocol Buffers. You will find out about good and bad. After this talk you should know, if you should use Protocol buffers in your project or not.

Safelyio Toolbox Talk Softwate & App (How To Digitize Safety Meetings)

safelyiotech

Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices. These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions. Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site. The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages. Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information. This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

Paul Brebner

Kafka Summit talk (Bangalore, India, May 2, 2024, https://events.bizzabo.com/573863/agenda/session/1300469 ) Many Apache Kafka use cases take advantage of Kafka’s ability to integrate multiple heterogeneous systems for stream processing and real-time machine learning scenarios. But Kafka also exists in a rich ecosystem of related but complementary stream processing technologies and tools, particularly from the open-source community. In this talk, we’ll take you on a tour of a selection of complementary tools that can make Kafka even more powerful. We’ll focus on tools for stream processing and querying, streaming machine learning, stream visibility and observation, stream meta-data, stream visualisation, stream development including testing and the use of Generative AI and LLMs, and stream performance and scalability. By the end you will have a good idea of the types of Kafka “superhero” tools that exist, which are my favourites (and what superpowers they have), and how they combine to save your Kafka applications development universe from swamploads of data stagnation monsters!
