Expat in Amsterdam: Starting Out

by

I’m wrapping up my first week as an Expat in Amsterdam. It’s been a great experience so far. I think one of the main challenges of moving to another country is that you may not speak the language. Although Dutch is the official language of the Netherlands, almost everyone speaks English fluently. That has certainly helped to ease the transition for us.

Also, the transportation options helped us to feel at home. We kept our OV-Chip Cards from our last visit. So all we had to do was reload and we could access the trams again. Trams are pretty much everywhere and they come often, perfect for getting around. There’s also ride services, like Uber, which can get you where you need to go.

Adapting

I spend lots of time behind a computer, and to be honest, not too much elsewhere. So imagine my surprise when we arrived at our temporary apartment and I saw the stairs…

Now apparently, steep, winding stairs is just a thing that is very common here. My first time up those three flights of death-defying stairs I had to sit down and take a break. But now that I’ve been up and down a few times, I’m good. Being in shape here seems like it will come without much extra effort. Who can complain about that?

This is Buttermilk

Another thing that baffled us initially was just buying milk. The Dutch have tons of milk options at the grocery store. We mistakenly bought Buttermilk (Karne melk) instead of Skim Milk (Halfvolle melk) twice! We laughed about it and then got it right the next time. I think that’s one of the best pieces of advice I have so far: laugh! You’ll make mistakes. Someone will get smart with you. You won’t know all the rules. Just laugh and enjoy this new adventure.

Getting Legalized

I had all of my documents prepared: Passports, Apostilled Birth Certificates and Marriage License; but I was still nervous. I just didn’t want anything to go wrong and delay our start in the Netherlands. The International Center is where you have to go to get your Citizen Service Number (BSN) and work permits. It was surprisingly friendly. They had a nice play area for kids and they were extremely efficient with getting us all processed. Once you have your BSN and permit, you receive a bag of goodies. The most useful of which is the book that describes everything you need to know in order to make it your first month.

Apps I Love

As an Android Developer, I’m naturally obsessed with apps. There are three that have proved extremely helpful to me this first week. The first is Thuisbezorgd.nl, it lets you order food online from local restaurants. Now there’s nothing especially novel about that. What’s cool about this app however, is that I was able to connect it to my PayPal account. This helped me avoid making a trip to get some cash when I first landed.

Also, my ability to speak Dutch is trash at this point. I can’t pronounce the names of things, especially streets. This app has helped me to avoid the extra stress for now. And I’ve discovered a great Indian restaurant in the process. The Chicken Madras is everything, try it if you can!

The second app is Rain Alarm. As the name implies, you get alerts for approaching rain. It rains randomly and often here. An alarm is a lifesaver. Finally, TransferWise has helped me to get my US money into my newly acquired Dutch Bank account with extreme ease and reasonable rates.

Wrapping Up

Besides finally meeting my daily step goal, I’ve been enjoying the amazing food! It’s my first week, so I’m indulging for sure. I’ve had a wonderful salmon salad, yummy pastries, and delicious lattes at various cafes.

Talk: RxJava in Baby Steps

by

Reactive Programming with RxJava has widely been adopted by both backend services and Android applications alike. Yet, the steep learning curve leaves many developers hesitant about adding it to their own Software tool belt. I was one such developer. Over the past two years, I’ve watched countless videos, read numerous blog posts and attended several conference talks on the subject. Yet, I often left each experience feeling only slightly more knowledgeable, but not quite empowered to start using RxJava in my apps. That’s not going to happen in this talk!

We cover the bare minimum concepts you need to grok, in order to start using RxJava today. In particular, we focus on:

  • The 3 O’s: Observable, Observer and Operator
  • The most common Operators: map(), flatMap(), and filter()
  • Understanding those Marble Diagrams

Reactive Programming is not going away any time soon. It’s a powerful way to create asynchronous, event-based applications. It allows developers the ability to craft applications that can easily combine multiple network calls, gracefully handle failures, all while providing a snappy user experience. I want everyone to feel comfortable with the basic concepts of RxJava. Today can be your first step…

This was my second time attending and speaking at the Droidcon NYC Conference. In 2015, my first conference talk was at this event. It was great to get back to New York and reconnect with many I met a few years ago. I put together a few highlights of what took place below:

@JvmSuppressWildcards My Biggest Annoyance with Kotlin

by

Over the past few months my team has been steadily moving our code over to Kotlin. It’s been a joy to get to work with such a succinct, yet expressive language. However, I have spent needless hours attempting to debug issues in my application that were all solved with the addition of this one thing: @JvmSuppressWildcards.
