Delivering things – from code to product
Everything I put together all updates of different aspects of life. The year 2019 is unique as it closes the decade.
This time I feel I finished the decade's race absolutely empty. There were too many emotional blips, and several personal projects didn't even see the light, but it's all about reflection on results!
In year 2019 one of the projects I launched was PronounceMe. It's a service which automatically generates videos with pronunciation of the English words and publishes them on YouTube. For more details about the hypothesis and technical implementation check out all posts under #PronounceMe
Unfortunately, I have to shut it down due to recent changes in the YouTube monetisation policies.
I have several post about the PronounceMe project experiments - automatic video and voice generator for English learners. If you missed previous posts please review #pronounceMe for more information about the project, ideas behind and some statistics. In this post I'd focus on the technical implementation with some diagrams and noticeable code snippets.
This is a part 4 of the #kotlin-showoff series and it's going to be about the standard functions over the collections(mostly iterables to be precise) allowing developer to express data modification in the clean and functional way.
Although one might think that kotlin has inherited all the base collection types from the Java it's not quite true. Kotlin transparently maps existing Java collections into the Kotlin by using some tricks such as typealiasing. Collections hierarchy in Kotlin make code even more safer by imposing separation between mutable and immutable data structures. Take a look on the interfaces diagram:
A while ago I have published post about the first skill for Alexa I developed. Personally I use it since then practically every day and I found it very useful. I didn't even bother to check analytics since, well, it does work for me and I expected people to use it as well if it's useful.
Thanks to my wife, I recently learnt London Bus Stop skill:

For folks who got lost on the word "extension functions" - it's a way to attach a function or property to the instances of the existing classes. For example, val d = 10.twice()It's very much like Utiltwice(int) but done in a very clean way. Visually it looks like you're calling a member of the class, but in reality, the compiler calls your function passing receiver as an argument.
Continuing series of posts #kotlin-showoff about functional constructions in kotlin I want to
Essentially, elvis operator lvalue ?: rexpression is returning left value if it's not null or executes rexpression otherwise. The crazy thing about kotlin is most of the constructions are expressions and that gives another way to express business logic.
For the seasoned Java
This is a first of this series of posts unioned by tag #kotlin-showoff
Five years ago I started one more journey when I landed for the first time at the Heathrow Airport from Saint-Petersburg. As expected, many things have changed. Since it's quite a date I want to reflect on the life.
I was invited for the talk as part of kotlin/everywhere at GDG Cloud London meetup on June 8th 2019. Unlike previous talks in this one I focused on the live coding part after brief intro into the language.
The demo project I prepared is a web site allowing user to upload pictures into GCP Storage, automatically annotate content using Vision API, synthesise voice which describes content of the image.
