A side note: it is difficult to derive the federal state from an Austrian postal code systematically. For example, postcodes beginning with 5 are not necessarily within Salzburg, but can also belong to Upper Austria. For the relatively small Burgenland, where most postcodes start with 7, some start with 2 (Lower Austria) or 8 (Styria). Lower Austria even tops this diversity...

I wrote an article on Medium about how to use Stencil Web Components in React apps with generated React wrappers and typings for efficient use with TypeScript and TSX.

Summer is calling!

That's why I created a new app that visualizes the water temperatures of all Austrian lakes, rivers and reservoirs on Google maps.

It provides information about:

• Water temperature
• Water quality (ranging from excellent to bathing ban)
• Water clarity / depth of sight
• Microbes / germs in the water

Available for iOS, Android & Web

Citybike Wien is a bike-sharing service where you can rent bikes for free for one hour. It is the cheapest and most eco-friendly choice to travel through Vienna.
There are currently 121 bike stations across Vienna, wich are available around the clock (24/7). You can borrow or return a bike anytime at one of the many Citybike stations.

Citybikes have been in Vienna for over 15 years and although scooters are supposedly the new hype, "Citybike Wien" still has clear advantages:

1. Citybikes can be rented for free for one hour.
2. Although scooters claim to be eco- friendly, only Citybikes are truly environmentally friendly because they do not require an engine and therefore do not need to be refueled or recharged.
3. Because they do not have to be recharged overnight, you can always borrow a Citybike at any time. Day and night, 7 days a week.
4. You can return your rental bike at any Citybike station that has an available box and thus keep the sidewalks free from parked bicycles.

This app provides you with up-to-date data on available bikes and available boxes in your area. Just take a look at the app and find everything at a glance:

• A map with all Citybike Wien stations (currently 121 stations, and still growing)
• Each station is visualized by a marker with 2 numbers: available bikes and available boxes.
• Real-time updates of all stations as soon as a bike is borrowed or returned.
• Find the nearest Citybike Wien stations near you.
• Street View: find stations interactively in a 360-degree panorama view.
• Distances: determines the exact distance, walking time and cycling time to the desired station.
• Directions: get the route to a Citybike station.
• Start an interactive visualization to see the utilization of all Citybike stations within the last 60 minutes in fast motion. This also creates heat maps with the most visited stations.
• Clearly recognizable markers for a station when no bikes are available or when there are no more availables boxes for returns.
• All important weather information at a glance: Current weather conditions, temperature, wind speed and more!

Hopefully the bike will soon become your preferred means of transportation in Vienna, whether you're planning a sightseeing tour, running errands or just taking a little bike ride with your friends. And the best part? It's environmentally friendly! #Bike-Sharing #FridaysForFuture

Did you notice? There's also a Citybike station in Salzburg! I added a marker on the map to create awareness for this awesome project!

I'm happy to share with you my broader vision of Bitcoin Monitor, my new app "Crypto Coin Check".

Crypto Coin Check expands on the concept of real-time price monitoring across exchanges. The brand new feature called "Cross Coin Check" gives you a broad insight into market developments and allows you to compare Bitcoin (BTC), Ethereum (ETH), Ripple (XRP), Bitcoin Cash (BCH), Litecoin (LTC) and IOTA (MIOTA) among each other. For this purpose, all exchange rates are continuously calculated and related with each other. It is important for me to emphasize that the prices are obtained directly and unaltered by the exchanges! That means, the exchange rates are not manipulated (keyword: Coinmarketcap).

You can downlod the app completely free and without ads from the App Store and Google Play:

Bitcoin Monitor

I created a little app for comparing cryptocurrency prices from Kraken, Coinbase, GDAX, Bitfinex, Bitstamp, Bitpanda & Coinfinity! It has support for Bitcoin, Ethereum, Bitcoin Cash & Litecoin with real-time exchange rates in Euro, Dollar & GBP. Make the best buy decision with real-time monitoring of Bitcoin prices across exchanges, visualization, lowest price detection, arbitrage potential calculation, change & volatility monitor and performance check between cryptocurrencies (BTC, ETH, BCH, LTC) with prices for €, $ and £.

Today I stumbled over an unexpected problem when trying PhoneGap/Cordova with Mac OS X 10.9 Mavericks. Building a project for iOS went just fine, but building for Android wasn't without some guesswork.

After installing Android 4.2.2 via the Android SDK Manager (I had to use the older API v17 since it wasn't compatible with a newer one) and adding the PATH environment variables for the SDK's platform-tools and tools, I thought I was ready to take off by running the command: phonegap run android.

Nevertheless, I got the following error:
