Openwords: open source (human) language learning”

by Marc Bogonovich

Marc will introduce the openwords platform about the open education concept and how to contribute the content for modern world.

About ‘Openwords Application’
Openwords has different learning modules. Including single word problems like hearing and simple review. We also have simple sentence construction problems, conjugation and fill in the blank problems. We’re even working on a handwriting learning module for Chinese (utilizing the Wikimedia Stroke Order project!). As we (or the community) develop new learning modules or games, we can add them in.
Importantly the teacher will be free to express the curricula they desire.
The Openwords app has a minimalist design. We believe languages themselves are beautiful. We also want to bring the community into the design process as we refine our current design. We’re happy to share more about our design concepts; we’ve thought deeply about these issues, but the process is open to you”

“Search as the new Data Warehouse”

by Grant Ingersoll, CTO and co-founder of Lucidworks

Examine the mapping of search engine capabilities onto modern data warehousing and data lake needs and weigh the pros and cons of such an approach by looking at use cases and capabilities of open source engines like Apache Solr and Elasticsearch.

“How to be a community-friendly startup in Japan”

by Machi Takahashi (高橋真知) & Nao Myoshu (明主那生), Stroly Inc.

As one of example cases, we worked with local community in Kyoto to make their map available on Stroly and used the Stroly map in their yearly evacuation drill. Moreover about the event, Map Cafe, is a community event for map enthusiast.
We organize walking tour and map creating event to research a creative cartography.

About ‘Stroly’
Stroly is a map platform using OpenStreetMap that allows you to experience and share the diverse stories within the place.With the birth of smart phones and map apps, it became easier to acknowledge our locations. The map apps function as tools to provide accurate information of your destination and of your current location. However, the information provided from map apps cannot share the stories of how the people living there have felt and thought throughout the time. Also, it is hard to imagine the shape of the city and what kind of stories will be created in the future.
Machi Takahashi is Co-CEO of Stroly and Nao Myoshu is Communication designer in Stroly.

“Kotlin 101”

by Mikhail Vink & Shengyou Fan

Kotlin is a new open-source programming language like Java, JavaScript, etc. It is a high level strongly statically typed language that combines functional and technical part in the same place. Currently, Kotlin targets Java and JavaScript. It runs on JVM.

Kotlin is influenced by other programming languages such as Java, Scala, Groovy, Gosu, etc. The syntax of Kotlin may not be exactly similar to JAVA, however, internally Kotlin is reliant on the existing Java Class library to produce wonderful results for the programmers. Kotlin provides interoperability, code safety, and clarity to the developers around the world.

About ‘JetBrains’
At JetBrains, code is our passion. For over 15 years we have strived to make the strongest, most effective developer tools on earth. By automating routine checks and corrections, our tools speed up production, freeing developers to grow, discover and create.
