00:00:14.340 Hi everyone, my name is Anton, and I'm from Lviv, Ukraine. You may have heard about this city or country, etc. My talk will be about coffee. This is my first time speaking at a software development conference, so I thought I should take it slow.
00:00:21.720 I started living in a café less than two years ago, and it's been quite an exciting journey that continues to bring me new impressions and tastes. Everyone is familiar with coffee, more or less. When you consume a lot of caffeine, it’s like an experience of its own. Also, this device is a classic coffee pot, but it's very hard to brew a truly good cup of coffee with it. I haven't yet mentioned how coffee cherries look. Coffee itself comes from these cherries.
00:01:01.640 The way you extract the seed from the cherry really matters for how the coffee will taste. However, coffee is typically prepared in a way that results in a standard, stable flavor. People love stability in coffee. This is more like what a good coffee should look like, but mostly it doesn’t, because people often opt for the method that guarantees a consistent result.
00:02:10.319 There are many ways to brew coffee, but today I will only talk about alternative brewing methods. For instance, the V60 is a simple cup with a hole in it that has become quite popular as an alternative brewing technique. Another one is the Chemex, which is slightly different. All these methods are generally classified as drip coffee, and it is better to use a special kettle to pour water over the coffee grounds.
00:02:44.280 You can control the brew better this way, and it significantly affects the outcome. If you haven't tried coffee brewed using these methods, you might think that brewed coffee all tastes the same, but it's actually quite different. I encourage everyone who's interested in coffee to explore these brewing techniques. The V60 is a great starting point because it's portable, and there are numerous recipes available for it.
00:03:58.260 Another method I use is cold brew. I have a setup at my office where I brew coffee for five hours using iced water and ice in the upper compartment, while the coffee grounds sit in the middle. To start exploring these methods, I recommend you visit a professional barista and try all of them several times, since you might not enjoy the first cup. Truly, experimenting with coffee can be a delightful journey.
00:05:00.420 As for introductions, I'm from a company that helps travelers get compensation from airlines for delays and cancellations. How many of you have flown in the past three years? Quite a lot! If you've faced any delays or cancellations, there's a chance you might be entitled to compensation of up to 600 euros. If you need help executing this claim, we can assist you.
00:06:01.650 Our service works on a commission basis, so we will only take a fee if we are successful in getting your compensation. If you have questions about the technology behind our service, come talk to me after the session.
00:08:08.070 Now, let's switch gears and talk about NPM. I won’t be too harsh on it, as many of us love it, especially when it streamlines processes like installing packages and running tests. However, issues often arise with managing dependencies in our projects.
00:08:45.300 For Ruby developers, managing dependencies can be a challenge, and while NPM does have some features like shrinkwrap, they don't always function effectively. Migrating to NPM version 3 improves this situation, and I’ll show you a demo on how to enforce specific versions in your package.
00:10:25.320 For example, I usually define my engines in package.json to specify the required NPM version. When I attempt to install under certain conditions, it can throw a warning if it does not meet the requirements. However, with some flags, you can ensure that NPM installs your dependencies correctly.
00:12:48.410 Moving on to image processing, I have two simple tips. The first tip is that most web applications focus on resizing and cropping images. Using libraries like MiniMagick can offer streamlined handling of images without exhausting memory. MiniMagick allows you to resize and crop images effectively.
00:14:35.490 My second tip is to use lossless image optimization tools. For instance, without losing quality, you can substantially reduce image sizes. Tools like ImageOptim allow you to clean up images and free up disk space, making them useful for optimizing applications.
00:16:06.310 Now, let's shift topics. My name is Bart, and I want to share some of the challenges I've faced while working under legacy code in transitioning a dating-related platform to modern technology using graph databases.
00:18:07.140 My task involved rewriting an older system that was poorly constructed with many inefficiencies. The current version consisted of numerous complex SQL operations and interactions that took too long to respond. Transitioning to a graph database like Neo4j helped streamline queries and made significant performance improvements.
00:20:30.780 Now, let's discuss Git. We all know the difference between linear and non-linear Git histories. Each strategy has its advantages and disadvantages, but managing your Git history effectively is crucial for understanding your project's evolution.
00:22:48.080 We’re often tempted to use tools to simplify Git workflows. For instance, utilizing a tool to streamline pull requests can significantly improve your workflow, allowing you to manage interactions without cluttering Git history.
00:25:15.130 By establishing clear patterns when merging pull requests, you can create a Git history that tells a story. If you use tools effectively, you can maintain a clean history that answers all necessary questions.
00:27:13.560 Hi, I’m Wojtek, and I want to talk about a new project I’ve been working on. Recently, I've realized that keeping up with security patches can be challenging, especially when managing legacy code.
00:29:21.020 It became clear when updating an old Ruby version that while the transition seemed straightforward, I was met with deprecated methods causing some complications. Deeply looking into the inner workings of the gems allowed me to find solutions to avoid these warnings.
00:31:14.630 Addressing these issues with object-oriented approaches and ensuring code compatibility with upcoming Ruby versions became essential. There are various reasons for not seeing a Windows 9, and one of them points to such compatibility issues.
00:33:34.530 As I wrap up, I invite you all to participate in an upcoming conference. It's an excellent chance to engage with like-minded individuals interested in Ruby development.
00:35:14.700 I’m Simon, and even if I am not familiar with systemd, I will take this opportunity to learn. I want to discuss using systemd for Ruby applications, specifically for managing services like Unicorn.
00:37:23.540 By defining how to start and reload your applications, systemd helps manage processes effectively, allowing for auto-restarts in case of failure. Setting environment variables can further streamline this process.
00:39:35.210 Implementing a basic systemd service configuration can significantly improve the reliability of Ruby applications. It's also useful to have health checks or notifications built into your system.
00:41:25.560 Finally, I would like to invite you to join me for a discussion about upcoming events and conferences within our community. Let's collaborate and connect on innovative ideas and developments.
00:43:37.660 Let’s come together and attend exciting events together, like ‘Drag Stock’. It's about meeting people, sharing ideas, and having fun at an amazing festival in Poland. Feel free to reach out to me for more information.
