IDE-agnostic tools allow developers to develop Adobe Experience Manager projects without being tied to a specific IDE, increasing flexibility and streamlining tasks. In their illuminating article, Krystian Panek and Dominik Przybył show how standalone CLI tools such as AEM Compose or bash scripts can be can be used with IntelliJ IDEA to automate various Adobe Experience Manager tasks. This article demonstrates how these tools can be used to automate pulling JCR content from an Experience Manager instance to a local codebase, or to execute Groovy scripts on an Experience Manager instance during development. Their article is an excellent resource for Experience Manager developers looking to optimise their daily workflow, and you can check it out by following the link in the comments below. ↓ #Adobe #AdobeExperienceManager #IDE

Next AWS User Group Wrocław meetup in a week (24.04.2024). 📅 24.04.2024 ⌚ 18:00 📍 Wędrówki Pub: https://lnkd.in/eeYukrXZ First of all, thank you ALGOTEQUE Innovation Hub for sponsoring our event! :) 🎤 Speakers: 🔭 Marcin Sodkiewicz (me) I am going to talk about #opentelemetry in my talk titled "Observability on AWS & OpenTelemetry". It's talk on the 300 level, but don't worry, I am going to cover all areas, and even if you are new to a whole concept I think you should understand everything. This is also a great opportunity to discuss your experiences with #opentelemetry. 📟 Grzegorz Kalwig: "Serverless is above limits? Our Path to production database cluster" If you don't know about it - Grzegorz is on a road tour with that talk as I believe I saw that he presented that material in many User Groups already. It means that his material is polished and he should be able to answer all your questions about Aurora Serverless v2. Super interesting and important topic, so stop by and make notes :) We are still part of JetBrains Community Support program. So we are going to give away some coupons for free access to IDE of your choice for a whole year.

🌟 The Full Agenda for WarsawJS Meetup #115 is Now Available! 🌟 We are thrilled to announce the complete agenda for the upcoming WarsawJS Meetup #115! Get ready for inspiring talks and outstanding speakers who will share their knowledge and experience. This event is a perfect opportunity to broaden your horizons in the world of JavaScript and TypeScript. Here’s what awaits you: ► Michał Miszczyszyn — The Power of Property-Based Testing in TypeScript / Strengthening Code Quality and Reliability Talk Description: Property-based testing is a technique for ensuring application correctness by generating tests based on a set of properties. In this presentation, we'll delve into the world of property-based testing in TypeScript. We'll explore how it enhances code quality and reliability, discuss the principles behind property-based testing, and showcase real-world examples of how it can uncover bugs and edge cases that traditional testing may miss. ► Szymon Mentel — Multi-tenant apps with single-tenant SQLite databases in global Tigris buckets Talk Description: Multi-tenancy is tough. Sharing resources fairly and effectively as well as ensuring secure code execution are just some of the challenges faced when dealing with the problem. But what if we approach it with single-tenant, isolated VMs mutating single-tenant database instances? Like, if a tenant’s request hits the system it gets routed to an exclusive tenant VM that uses an exclusive tenant’s database. The talk explores an unconventional architecture of homogenous Node.js servers running on top of single-tenant Fly Machines hosting single-tenant SQLite databases stored in globally replicated Tigris buckets. ► Mieszko Sabo — Type level programming in TypeScript Talk Description: During the presentation, we will look at the type system in TypeScript, approaching it as an independent programming language. I will show how we can use types to express mechanisms known from other languages, such as loops, functions, conditional expressions, etc. Are you curious about how crazy things the type system in TypeScript allows you to do and how you can use its full potential for your everyday work? After my presentation, the possibilities of the type system will become clear to you, and you will learn how you can further expand your knowledge towards programming on types. The upcoming meetup is a unique opportunity to delve into advanced programming techniques, discover modern approaches to application architecture, and unlock the full potential of TypeScript. Don’t miss this chance! 🎟 Tickets are now available! Reserve your spot now: https://lnkd.in/dHhc4pxc 🏢 Venue: Box, ul. Chmielna 69 (22nd floor), Warsaw 📅 Date: 12.06.2024 ⏰ Time: 18:30 Join us at WarsawJS Meetup #115 to explore new horizons in the IT world together and get inspired by the best! We can’t wait to see you there! See you in less than 2 weeks at our Meetup! 🚀 #WarsawJS #Meetup #Programming

📌 How to get a job in an IT company: features of the hiring process 📌 The IT industry is actively developing and has high demand for qualified specialists. However, the hiring process in tech companies has its own peculiarities. Let's look at the main stages and nuances of getting a job in IT. 🖇 First, you need to find relevant vacancies. It is best to look for them on specialized resources such as DOU, DJinni, Work.ua, LinkedIn. Many IT companies also post ads on their own websites. 🖇 Secondly, carefully study the requirements of the vacancy and make sure that your experience and skills meet the employer's expectations. 🖇 Thirdly, prepare a resume and cover letter tailored to a specific vacancy. Talk about your projects and achievements using keywords from the job description. 🖇 Fourth, be prepared to complete test assignments and several interview stages. IT companies check not only technical skills (hard skills), but also personal qualities (soft skills). 🖇 Fifth, show that you are interested specifically in this company during the interview. Ask questions about corporate culture, technology stack, career growth prospects. 📌 So the main thing in the IT hiring process is to demonstrate compliance with the requirements of the position and motivation to work specifically for the chosen company. 🌟 Value your time and experience, and you will definitely find your dream job! #lumenglobal #recruiting #hiring #article

📣 Presenting the full agenda for WarsawJS Meetup #117! 📣 The event will take place on August 14th at the fantastic BEC Poland headquarters. Check out what we have prepared for you: ► Robert Pasiński — Deep Dive into JS task scheduling We’ll go deep into what are tasks in JavaScript context, what is the difference between micro-task and macro-task, when they are run and how they are scheduled. I’m gonna go through the APIs like requestIdleCallback, requestAnimationFrame, and other that allow us to leverage the scheduling mechanism and highlight the bottlenecks. You can also expect a glimpse of how these are implemented under the hood in JS engines. ► Inez Okulska, — RAG vs GPTs fine-tuning - who wins? Natural language interfaces for information retrieval are very appealing. Hence, the popularity of GPTs for quick fine-tuning of GPT models. Are they reliable enough, though? When and why do we need more complex solutions like RAG systems? We’ll analyze this using the hAI Magazine case study. ► Jerzy N. — How to build real-time video processing web app Do you want to create a real-time video processing application? That's excellent, but have you considered how to handle delays, video compression, and high infrastructure costs? At ShareTheBoard, we thoroughly analyzed these challenges, tested various approaches, and ultimately succeeded in developing a web application that allows you to share digitized data with remote meeting participants. In this session, we will discuss the biggest challenges we faced and describe our final architecture. Join us to listen to experts in their fields and learn more about JavaScript, GPTs, and real-time video processing. It’s a great opportunity to gain new knowledge and make valuable connections! 🧠👥 🎟️ Tickets available here: https://lnkd.in/dtZmKC5G We can't wait to see you at WarsawJS Meetup #117! 🫂🤝 #WarsawJS #Meetup #TechEvents #WebDevelopment
