Hello, world. Let me share some of my findings of Haskell and Swift. I got interested in functional programming, especially in Haskell, when I realized that most of my favorite Swift features come from functional programming. My favorite features include enum with associated values, Result type, higher-order functions (i.e. passing functions themselves), KeyPath type, and so on. After started learning Haskell, I found there are more common features between Swift and Haskell than I expected. Some data types are essentially the same, some syntax is similar, and some concepts are common. In fact, Chris Lattner, who is the main author of Swift, confirms that Generics in Swift is inspired by Haskell according to an interview. ...

Hello, world. I’m going to share my report on the second quarter of 2021. Fortunately, I could start working on a client project, learned new stuff, and attended some events! I hope to see some more progress in Q3. By the way, in the Netherlands, April and May were quite cold😰 (April was the coldest April in 35 years in NL!), it became warm☀️ (almost suddenly) in June. Client work Coral app Apple/Google SignIn, Push Notification (FCM), some new screens, some investigations, and bug fixes. Thank you, Coral team! I’m open to working on more projects on a part-time basis or short-term projects. Contact me if you need my help! ...

While preparing for my new life and business in a new place, which is in Amsterdam, the Netherlands, since November 2020, I used a lot of time to learn new things. Since 2015, when I started working on iOS app development, I’ve focused on iOS/Swift things and haven’t spent much time learning outside of the iOS/Swift world. This was a strategic choice and I learned a lot by exploring Swift. However, I felt the time has come to learn outside of iOS/Swift, to have broader and deeper knowledge about software development. ...

It’s been about 10 months since I moved to Prague. I’m not sure how I could summarize my days because so many new things have happened and so many feelings have come in and gone by since I moved here. Sometimes it’s difficult to recall what I was doing and feeling and my memory is sometimes confusing, however, I’d like to write things down so that I will be able to recall these feelings in the future. Even though this is a very personal summary, I wish this gives you some insights into a relocation experience. ...
