Vuejs Amsterdam 2022

Reading Time: 5 minutes

Amazing speakers, interesting topics, great venue and everything nice – this were the ingredients chosen to create the perfect conference – Vuejs Amsterdam.

Last month me and my coworkers were sent on a mission, to improve our knowledge, become better developers and expand our views. So we decided to visit the best known Vue conference in the world.

The only constant in the technology industry is change

Marc Benioff

So what better way to keep up with that change rather than visiting a conference where the best speakers are gathered with the latest updates and you get to be one of the first people to hear them?

VUEJS AMSTERDAM

Vuejs Amsterdam is an event which took place on 2nd and 3rd of June 2022. According to their website, these were the numbers for those 2 days: 

Number of speakers – 20+ Vue core members
Number of attendees – 1000+ daily
Global audience from 20+ countries

The conference was held in Amsterdam theatre, in one of the most beautiful venues I’ve ever seen. One thing that I liked the most was that there was only one main stage, so we could listen to all the presentations, without having to choose from multiple presentations and multiple stages at the same time. The atmosphere in the venue was amazing. Everybody seemed like they had a great time, participating in interesting trivia games and quizzes and enjoying the wonderful food!

Also, I must say, visiting Amsterdam in such a nice weather was a big plus.

Conference recap

Here are some notes from my favourite speakers and topics:

State of the Vuenion 2022 – Evan You

  • Evan You is the creator of Vue, so I think that this was the best way to open the conference, even though his presentation was remote. The topic that he presented was about the current state of Vue.js, latest news and upcoming changes.
  • So the current state is the following:
    • Since 07.02.2022 Vue 3 is the default version
    • There is a brand new documentation 
    • Vue 3 +70% since default version launch, 4x downloads more than last year, 25% of all Vue downloads
    • Vuetify beta 3 release – May 19th 2022
    • Vue 2.7 – built in composition api (without plugin), moved Vue 2 codebase to Typescript, final minor release for Vue 2, EOL end of 2023

Getting more out of your Pinia stores – Eduardo San Martin Morote (creator of vue-router)

  • Pinia is a Vue store, successor of Vuex 
  • Has great documentation https://pinia.vuejs.org/
  • Vue 2 and Vue 3 compatible
  • Lighter than Vuex
  • Based on the Composition API 
  • Has a huge potential to replace Vuex
  • Here is an example usage:
import { defineStore } from 'pinia'

export const useCounterStore = defineStore('counter', {
  state: () => {
    return { count: 0 }
  },
  actions: {
    increment() {
      this.count++
    },
  },
})
import { useCounterStore } from '@/stores/counter'

export default {
  setup() {
    const counter = useCounterStore()

    counter.count++
    // or using an action instead
    counter.increment()
  },
}

Fast stories powered by Vite: Histoire – Guillaume Thru

  • Histoire is an interactive component playground powered by Vite
  • One of the most memorable moments in the conference was when the speaker changed the repository from private to public, and it was an honour to be present at that moment
  • https://histoire.dev/

Local state and server cache: How to balance them with vue-query – Natalia Tepluhina

  • One of my favourite speakers
  • There were three main questions at the beginning of the presentation
    • How to fetch only when data is not fetched already?
    • How to keep my data up to date?
    • What if two components start fetching simultaneously?
  • The answer to these questions is using vue-query – package which provides hooks for fetching, caching and updating data in Vue
  • The vue-query setup has some really interesting props which can be set for the configuration: 
    • retry – number of times it should refetch if there is an BE error
    • refetchOnWindowFocus – decides if it should refetch the data every time we do a tab switch
    • placeholderData – initial data before fetching
    • staleTime – interval of time while client considers your data being okay and there is no need to fetch it again

Vue 2 to 3 migration – a real life experience – An Phan

  • I think this is the topic that everyone was most interested in, because as Vue developers this is a problem which we are facing or will be facing in the near future.

Conclusion

I think that these kind of events are super important for learning new things, networking, getting inspired and keep up with the technology. On top of that, listening to the Vue core team members was definitely something that I will never forget!

WeAreDevelopers World Congress 2019 – Expectations

Reading Time: 3 minutes

Why this one?

I’m a mobile developer. In specific an iOS developer. So guess what, I love writing code either in Swift or Objective-C for Apple devices. When searching for a conference to attend in 2019 I rather had the WWDC in mind. There is one drawback, however you need some serious money and luck to get there. But in general, there are plenty of other good iOS conferences to attend (NSConf, CocoaConf, …, you name it!). 

For an overview and a brief description of iOS conferences in 2019 I found this page from Hacking with Swift very informative.

There is a very nice overview diagram of iOS conferences depending on your location and/or budget in an old post (2017) at raywenderlich.com. Although outdated, most of these conferences will also happen in 2019 and pricing and location rarely (dramatically) change.

Wait, but the post is about your expectations for the World Congress 2019 in Berlin. So what happened?

Ok, let’s get to this. When searching for iOS conferences in 2019, this conference somehow slipped into the search results. And it did so because Steve Wozniak was speaking there. Well, which iOS/Mac developer wouldn’t want to see and hear the legendary Steve Wozniak, right?

Once on the WeAreDevelopers homepage I realised that Steve Wozniak was giving a talk there a year earlier. So, 2018 in Vienna. Furthermore, this conference isn’t iOS or even mobile specific. That’s another drawback. Anyway, once on the page I skimmed through this year’s speakers. Here are some of them:

  • Rasmus Lerdorf – Inventor of PHP
  • Håkon Wium Lie – Inventor of CSS
  • Andreas M. Antonopoulos – Author, Mastering Bitcoin

Well, maybe Steve Wozniak is not there, but there are a lot of high quality people from IT in general. People who had and have a tremendous impact on millions of developers out there. One can argue about the weaknesses and strengths of PHP, CSS, Bitcoin. But one is for sure. With all downsides, these technologies are used and working on a daily basis. Furthermore, there are vibrant communities behind them.

Ok then. I’am going because I would like to see a broader picture of tech then just a little piece of it.

Btw there are mobile related talks anyway.

Expectations (TL;DR)

  • Experience some good talks from people with impact
  • Get a feeling where we’re headed in the future
  • Maybe see some demos/MVPs on AR/VR, Robotics
  • Get answers where bitcoin and blockchain are going and what the state of disruption is
  • Socialising

FrontCon 2019 in Riga, Latvia

Reading Time: 3 minutes

Only a few weeks left until I go to my first tech conference this year. Travelling means for me learning something new. And I like learning. Especially the immersion in a foreign culture and the contact to people of other countries makes me happy.

It’s always time to grow beyond yourself. 🤓

BUT why visit Riga just for a conference? Riga is a beautiful city on the Baltic Sea and the capital of Latvia. Latvia is a small country with the neighbours: Russia, Lithuania, Estonia and the sea. AND it’s a childhood dream of me to get to know this city. 😍

The dream was created by an old computer game named “The Patrician”. It’s a historical trading simulation computer game and my brothers and I loved it. We lost a lot of hours to play it instead of finding a way to hack it. 😅
For this dream, I will take some extra private days to visit Riga and the Country as well. 😇

Preparation

The most important preparation such as flight, hotel, workshop and conference are completed.

Furthermore, I also plan to visit some of the famous Latvian palaces and the Medieval Castle of Riga. I also need some tips for the evenings: restaurants and sightseeings from you. Feel free to share them in the comments. 😊

Some facts about the conference

There are four workshops available on the first day:

  • Serverless apps development for frontend developers
  • Vue state management with vuex
  • From Zero to App: A React Workshop
  • Advanced React Workshop

I chose the workshop with VueJS of course 😏 and I’m really happy to see that I can visit most of the talks in the following days. There are some interesting speeches like “Building resilient frontend architecture”, “AAA 3D graphics” and secure talks and server-less frontend development. Click here for the full list of tracks.

My expectations

Above all, I’m open to events to learn new things. Therefore, I have no great expectations in advance. So I’m looking forward to the

  • VueJS & Reacts parts
  • Visit the speakers from Wix, N26 and SumUp

I’m particularly curious about the open spaces between the speeches. I will be glad to have some great talks with the guys. 🤩

For my private trips:

That’s all for now

My expectations on JPoint Moscow 2019

Reading Time: 3 minutes

PREPARATION

Tickets

Tickets for individuals: 280€ until 1st March.
No possibility to change the participant.

Personal tickets may not be acquired by companies in any way. The companies may not fully or partially reimburse these tickets’ costs to their employees.

Standard tickets: 465€ until 1st March. A possibility to change the participant is given.

Tickets for companies and individuals, no limits. Includes a set of closing documents and amendments to the contract.

Flight

Skopje-Vienna-Moscow. Visa for Russia is needed!

Hotel

I guess a hotel like Crowne Plaza Moscow – World Trade Centre is a good option, because it’s in the same place where the conference takes part.

DAY 1

So what are my plans and expectations for the first day of JPoint. I will start with Rafael Winterhalter who is a Java Champion and will talk about Java agents. It will be interesting to see how Java classes can be used as templates for implementing highly performant code changes.

Next stop will be the creator of Jenkins: Kohsuke Kawaguchi. He has great headline Superpowers coming to your Jenkins and I am exicted to see where Jenkins is going next.

Last stop for day one, Simon Ritter from Azul Systems, with focus on local variable type inference. As with many features, there are some unexpected nuances as well as both good and bad use cases that will be covered.

There will be many more for day one but I will focus on these three for now. Also at the end, party at 20:00.

DAY 2

I will start the second day with Simon Ritter again, this time with focus on JDK 12. Pitfalls for the unwary, it will be interesting to see all the areas of JDK 9, 10, 11 and 12 that may impact application migration. Another topic will be how the new JDK release cadence will impact Java support and the choices of which Java versions to use in production.

Other headliner talks for the second day are still under consideration, so I’m expecting something interesting from Pivotal and JetBrains.

Feel free to share some Moscow hints or interesting talks that I’m missing.

Voxxed Days Bucharest & Devoxx Ukraine – HERE WE COME!

Reading Time: 4 minutes

Last year conferences

Already in 2018, we had the pleasure to visit 2 conferences in Europe:

We had a great time visiting these two cities 🙌 and we can’t wait to do that again this year 😎.

What do we expect from the two conferences in 2019 👤💬?

Like last year, we are interested in several different topics. For me, I am looking forward to Methodology & Culture slots, Shady is most interested in Java stuff. All in all, we hope that there are several different interesting speeches about:

  • Architecture & Security
  • Cloud, Containers & Infrastructure
  • Java
  • Big Data & Machine Learning
  • Methodology & Culture
  • Other programming languages
  • Web & UX
  • Mobile & IoT

We ❤️ food!

The title is speaking for itself. We just love food 🍴! Travelling ✈️ gives a good opportunity to see and taste something new 👅. All over the world, every culture has unique and special cuisine. Each cuisine is very different because of the different methods of cooking food. We try to taste (almost) everything when we arrive in new countries and cities.

We are really looking forward to seeing, what Bucharest’s and Kiev’s specialities are 🍽 and to trying them all! Here some snapshots from our trips to the conferences in Amsterdam Netherlands and Krakow Poland in 2018…

What about the costs 💸?

One great thing at N47 is, that your personal development 🧠 is important to the company. Besides hosted internal events and workshops, you can also visit international conferences 🛫 and everything is paid 💰. Every employee can choose his desired conferences/workshops, gather the information about the costs and request his visit. One step of the approval process is writing 📝 about his expectation in a blogpost. This is exactly what you are reading 🤓📖 at the moment.

Costs breakdown (per person)

Flights: 170 USD
Hotel: 110 USD CHF (3 days, 2 nights)
Conference: 270 USD
Food and public transportation: 150 USD
Knowledge gains: priceless
Explore new country and food: priceless
Spend time with your buddy: priceless

Any recommendations for Bucharest or Kiev?

We never visited the two cities 🏙, so if you have any tips or recommendations, please let us know in the comments 💬!

My humble expectations on Devoxx Poland 2019

Reading Time: 2 minutes

Five months and devoxx.pl in Krakow has already finished again. That leaves me some time for preparation and anticipation.

Preparation

Key preparations like conference ticket, flight and hotel are done. However, I would be grateful for sightseeing hints for the evenings. Feel free to share them in the comments section.

There are five different tickets available. Generally, you have three alternatives with some optional sugar in form of dinner or gifts.

  • Conference only
  • Deep Dives only
  • Combi (both of them)

I’ve chosen the conference only ticket because I prefer to attend more but shorter slots as the speakers are forced to focus on the key parts. I also liked this format in my last visit at Devox Belgium in 2017.

Anticipation

There is not yet a published schedule but only the list of tracks:

  • Web & HTML5
  • Cloud & Big Data
  • Server Side Java
  • Future <Devoxx>
  • Mobile
  • JVM Languages
  • Methodology
  • Java SE
  • Architecture & Security

And now, those are my expectations for Devoxx Poland

  • New Java language features in 11 and 12.
  • From monolith via microservice to serverless. What’s the next thing?
  • Learn about some new fancy JS frameworks.
  • What’s new in the mobile world and which approach will make us happy: native, hybrid, web views, …?
  • Insights into JVM release roadmap and Oracle subscription models.
  • Enjoy some typical Polish foods and drink.
