Being a teamlead is like being a teenager's parent. You shouldn't overcontrol, you should let them fall, make mistakes and grow. But they need to know that you are always near so they can ask for help. And of course they need to respect you as a developer and as a person. #teamlead

You might be leaving money on the table. Yesterday I started to play a bit with Coolify, a Heroku, Netlify and Vercel alternative as they describe in their website. To be honest? I would say that they are alternative to other important tools out there, such as Forge and Runcloud (created for or mainly known because of Laravel). It's a great solution that you can self-host or use their cloud to control your server, allowing you to deploy static website, docker based projects, Nixpacks that auto detect the stack, or you can use the one click install apps as well. In the comments I'll leave the link of the creator. He build it in public and you can follow all the process as well as contribute if you are able.

This is the last sale I will do for my #Angular Change Detection ebook. The content in there is still valid 🚀 And I promise it will help you understand Angular way better. It's an absolute steal 24 - 18 = 6 € excl VAT (limited)🤑 Not up to date with signals and experimental zoneless. Angular 16 This book is special for me because it is the first piece of paid content I created for simplified courses and I'm glad I sold hundreds of copies. For anyone who has supported me in buying that book, thank you so much. It was a real motivator. https://lnkd.in/ecgVs6mg Next focus: Building/Maintaining huge #Angular codebases course.

State management is a challenging software engineering topic. State creates dependencies, and dependencies create complexity. Therefore we need to understand how to manage state. I recently heard someone say that we should aim to remove all raw for loops from our C++ codebases and replace them with std algorithms. At first I didn’t grasp his point, but I soon began to realize that he was trying to explain that raw for loops expose state. We don’t want to expose state, instead we want to encapsulate and manage state. Managing state was the topic for my talk at the Audio Developer Conference ‘23. In this talk, I share my thoughts about it in the context of JUCE (a C++ audio software framework) applications. In audio software, we have to deal with different forms of state including global settings, presets, UI state, and application state. State must be stored and restored and must be synchronised throughout the app across different threads (at least the audio and main thread). State sometimes needs to be synchronised with other software, such as a DAW (Digital Audio Workstation). There is a lot of debate about how to solve all these problems, and I’ve seen a lot of people do this in different, some good and some bad, ways. How you do it matters. It all starts by knowing the JUCE framework and understanding the fundamental JUCE objects, including the AudioProcessorValueTreeState, ApplicationProperties, Value and Vars. Knowing these objects will help you to build up a state system that suits your application. You can watch my talk now on YouTube! Go ahead, watch it, and feel free to send me a message with any question or comments afterwards. #softwaredevelopment #juce #audio #c #plugins #statemanagement

GDP per capita between Sweden and Netherlands are quite close. Netherlands (62K USD) Sweden ( 56K USD) However, software engineering salaries are not that close. Sweden considered tech unicorn of Europe but with the weak krona and limited salary bumps software engineers are earning less and less after covid.

Day2 I once came across a saying by Marijn Haverbeke: "You should imagine variables as tentacles, rather than boxes. They do not contain values; they grasp them—two variables can refer to the same value". Reflecting on the differences between var, let and const in JavaScript. They are generally keywords used to declare variables in JavaScript. ✍️Var This is the oldest keyword. It can be reassigned. It can be redeclared. It is a function scope. ✍️Let It can also be reassigned. It can not be redeclared. It is a block scope. ✍️Const Can not be redeclared nor reassigned. It is a block scope . ♣It is generally recommended to use "let" and "const" over "var" when declaring variables in JavaScript because they have more predictable behavior.

Do you really think that Leetcode and its companions are suitable to assess the knowledge of a medior/senior? This is a huge misconception, I experienced it myself as both a professional recruiter and a candidate. A targeted interview is much more suitable, or practical exercises such as Coding Challenges. #softwaredevelopment #recruitment #donothumiliatetheexpert

At Evoluted | Certified B Corp™, we've been using GitLab as our DevOps platform for years, and it's been fantastic. But as our Shopify client base has grown, we faced a challenge: no built-in GitLab-Shopify integration. Many developers solve this by building custom solutions. That's what I did! Over the past 6 months, I've developed an integration leveraging GitLab CI/CD and the Shopify CLI to automate theme deployments. Here's the benefit: Streamlined development workflows for Shopify stores on GitLab. It's not a silver bullet: This solution might not be as feature-rich as the official GitHub integration, but it's robust and ready to share. Calling all Shopify devs! Have you struggled with manual deployments? I'm sharing these scripts to help you improve your workflow, just like they've helped ours at Evoluted. Links to the full breakdown of the implementation: In the first comment. #shopify #gitlab #devops #ecommerce #cicd

Elixir: Happy Developers and Scaleable Backends? Listen to Sanne 🌟 Kalkman from CodeSandbox this week during DEVWorld Conference online to her talk on #Elixir. 👉 Sign up to replay via https://lnkd.in/eZUKXrGd According to the 2023 Stack Overflow Developer Survey, Elixir is the second most loved programming language, and its web framework Phoenix takes the number one spot in most loved frameworks. Not only is Elixir a joy to work with, it is also an excellent choice for highly scaleable and fault-tolerant backend systems and is an important part of successful tech companies such as Discord and Podium This talk will highlight the main ways in which Elixir differs from other commonly used backend languages like #JavaScript or #Ruby. Then, it will give developers from other languages an introduction into OTP, the underlying framework that makes it almost trivial to build concurrent and highly fault-tolerant systems in Elixir (and Erlang). Lastly, Sanne will highlight some of the specific ways in which Elixir and #Phoenix have allowed CodeSandbox to grow and move quickly with a very small team of #backend developers. The overall aim of this talk is to introduce otherwise experienced #developers to a language and ecosystem they are not yet familiar with, and hopefully inspire them to give Elixr and Phoenix a try for their next project. #devworldconference #devworld #futurism #technology #amsterdamconference #conference #amsterdam

🎤 I'm speaking again today (07.05) at #HelsinkiJS and discussing how the stateless first architectural choice for frontend development aids in making your life easier 🛠️ for implementing robust, loosely coupled tests for your code. As part of the talk, I will be going through why this approach makes your frontend code more maintainable 🔄 when considering refactoring and updating your codebase in the future. Additionally, I'll be showing a basic introduction to how to use testing-library to test the frontend code.

☝️ Things I didn't knew CSS could do. ...but now I do! 💡 On the very first edition (and the very first day even) of #FrontendNation, the largest free online frontend conference, I took the virtual stage to talk about CSS. About generous amount of features that were added to the #CSS spec and can replace your #sass or #JavaScript solutions. It's also a talk about learning about knowledge gaps and taking action when identifying them. It's okay to not know every latest technology (and there are plenty in the frontend space), as long as you know what to do if you encounter lack of knowledge. ...and that talk is online, free to watch: https://lnkd.in/eVMi28Fe 🍿

🚀 Exciting Update! 🚀 We've noticed a low conversion rate when it comes to updating to a newer version of our app. To address this, we've introduced a handy #Update banner in #Gitabitan version 2.1 whenever a newer version is available. We can't wait to see how this impacts the overall app version distribution for our upcoming event releases. Stay tuned for more updates! #AppDevelopment #UserExperience #SoftwareUpdate #TechInnovation

Ruby as fast as Go? 😳 In my first implementations I ended up having this result. A minimal difference as you can see in print. For 1 second I was scared. hahaha But I already knew what had happened. Because I already had good experience with Ruby, I ended up implementing more efficient code. Basically, the result I'm showing in the printout was because in Ruby I had implemented a "connection pool" for the database. This pool manages reusable database connections, limiting the concurrent number of connections and improving efficiency and performance in multithreaded applications. And I hadn't done that in Go. The difference in performance was minimal in this case. Follow me to see the next posts. 😉 #Ruby #Go #Golang

⚡ Shocking but software doesn't run for free... ⚡   🌱 Last week, I had the pleasure of attending the 2nd meetup in Amsterdam of Green Software Foundation - The Netherlands 🇳🇱. While I already knew a lot about Green Software, the presentations reinforced the concepts and added great perspectives. I also enjoyed sharing and hearing from others about what made them interested in Green Software. Of course, the immense carbon footprint of LLMs/AI had to be mentioned, specifically by estimating the impact using the Software Carbon Intensity (SCI), which has recently become an ISO standard, through the Impact Framework. 💡 My biggest takeaway was that you should first optimize system utilization, addressing the embodied carbon in servers and the issue of underused servers, before focusing on optimizing the software itself. This can be seen as the "low-hanging fruit." 💧 Secondly, Wilco's presentation reminded us to consider the impact and measure it. Fortunately, I work at HULO.ai, where we strive to make a significant impact by saving a lot of drinking water through better leak detection and localization. 🚀 From the start, HULO.ai has cared about its (software) footprint, and luckily our software does not require huge amounts of data to be trained. As a startup, there is still a lot of work to do, but I believe we will continue to improve and keep tackling the impact we make each day! 🏆 Thanks to Wilco Burggraaf for the invite and Vandebron for hosting the event. 🎓 To learn the basics of Green Software, take the very short course on https://lnkd.in/eyTCWFhn 📆 They will organize many more meetups, so follow https://lnkd.in/eQpgSARX #greensoftware #meetup #impact #ai Frank van der Hulst | Laura Garzon Useche | Robbert Lodewijks | Redmer van Netten | Rudy Dijkstra

🧑‍💻 Update on the HTTP server I was working on: A few weeks ago I sat down and coded my own HTTP server which runs on NodeJS environment. After a while, I finally revisited the repo today to implement gzip compression in my server. My server can now respond with a buffer to your GET request if you include "gzip" in your "Accept-Encoding" header -> Which is essentially the compressed text. 𝐰𝐡𝐚𝐭 𝐢𝐬 𝐠𝐳𝐢𝐩 𝐜𝐨𝐦𝐩𝐫𝐞𝐬𝐬𝐢𝐨𝐧 𝐚𝐧𝐲𝐰𝐚𝐲𝐬? It is a data compression technique to compress mostly text files. It is widely used to compress web content like HTML, CSS and JS files, which can be large text files. To transfer these files efficiently, servers use data compression techniques like gzip to decrease the size of your text files first and then send them over. You can check out my code in this github repo: https://lnkd.in/gVp9hJW6
