Last Week I identified issues with the database design (and by extension my data layer logic). The work to redesign the database and code refactoring has begun. What does it mean in English? Imagine you’re building a house. Instead of throwing everything together in one big mess, you’d organize construction into layers: foundation, framing, electrical, plumbing, finishing, etc. Each layer has its own purpose, and specialists work on each part....
Last Week The entire UI is overhauled. Improved user experience on latency-sensitive operations by using optimistic updates. What does it mean in English? Optimistic updates is a user interface design pattern that makes applications feel faster and more responsive by immediately reflecting user actions in the interface before receiving confirmation from a server or backend system. In traditional (“pessimistic”) UI approaches, when a user performs an action like liking a post or deleting an email, the interface waits for confirmation from the server before showing any change....
Last Week The landing page is beautified. However, I spent the majority of my time exploring a power AI assistant to rapidly increase my throughput. Tools used: Claude 3.7 Sonnet ($20/month) What does it mean in English? I asked an AI agent to write the app code for me instead of me doing it myself. Nerdy Details Asking an AI to make an app is not as straightforward as I thought....
Last Week I contemplated philosophically while sipping on mojito. Next Week Get back into the development groove and further improve the landing page.
Last Week The landing page after a user logs in is complete. A simple drawer is also implemented. Tools used: Model-View-Intent (MVI) design pattern What does it mean in English? A full-fledged app on a device (e.g., phone, laptop, etc) is a miracle cornucopia of complex software components: somebody needs to refresh the screen (60 times a second!), somebody needs to monitor user interaction (e.g., tap, drag, etc), somebody needs to talk to the internet and fetch information, somebody needs to save stuff to local storage, so on and so forth....
Last Week Development derailed. I got sucked into this AI thing. Wound up setting up a local private AI stack. Below is an example of me asking AI to code for me and its response in real time on local hardware with anonymized internet search. Since it is shown in real time, it is a bit slower than what we might be used to from places like public ChatGPT....
Last Week Supabase Postgres Database is investigated. First table is in. Data classes set up for database. App can now read and write the database. What does it mean in English? An app needs to store information. It could store it on device. But in many cases it’s more helpful to store it in the cloud (which is just somebody else’s computer that is always connected to the internet) such that the functionality of the app is not dependent upon one device....
Last Week Login page is beautified. Basic input validation is set up. When any error is detected, the login screen is reset and a snackbar message is displayed. What does it mean in English? George Carlin once uttered the wisest of words: “Imagine an average stupid person and then realize that half of the population is stupider than that.” Even if your users are all saints and none seeks to destroy your app with malice, you still need to carefully handle the fruits of their stupidity....
Last Week Supabase auth is implemented with One-Time Passcode (OTP). Tools used: Authentication Service: Supabase Auth (free to start) Dependency Injection Library: Koin Dependency Injection (free) What does it mean in English? An Authentication Service makes sure the user is who they say they are. In this particular implementation, when a user tries to login with their email address, an authentication server (i.e., a powerful computer) sends a random number to the user’s email address....
Last Week All screen files for the initial version of the app are now in place. Screen navigation is set up. Tools used: Development Platform: Kotlin Multiplatform (free) User Interface (UI) Framework: Compose Multiplatform (free) Navigation Library: Compose Multiplatform Navigation (free) What does it mean in English? A Development Platform translates my code into languages the end devices understand. In other words, I write in (mostly) English, the platform translates it into ones and zeroes....
