    I switched to eSIM in 2025, and I am full of regret

    eSIM technology is replacing physical SIM cards in modern smartphones, with Google's Pixel 10 series becoming the latest to drop the physical SIM slot. While eSIMs save space and allow multiple profiles, the transition has proven frustrating for users accustomed to easily swapping physical SIM cards. Apple pioneered the eSIM-only approach with the iPhone 14, though the space savings have been modest—around 8 percent more battery capacity. The shift represents a significant change in how mobile subscribers manage their phone service, moving from removable cards to programmable, soldered components.

    Open letter claims mobile gamedev is "ignored" because industry perceives it as a "world of predatory monetization and low quality"

    Midjiwan AB CEO Christian Lövstedt published an open letter criticizing the gaming industry for overlooking mobile games despite representing 55% of the global gaming market. He argues mobile gaming is dismissed due to perceptions of predatory monetization and low quality, pointing to award bodies like BAFTA and D.I.C.E. rarely recognizing mobile titles. Lövstedt contends that industry awards and media shape cultural narratives and calls for acknowledging mobile as the largest and most creative gaming platform.

    Vibe Coding is Mad Depressing

    A mobile developer with 15 years of experience reflects on how AI-generated code has negatively impacted their freelance work. Clients now submit AI-generated code snippets and entire features, leading to messy codebases with poor practices like thousands of branches, emoji-filled print statements, and all logic crammed into a single ContentView file. The shift from structured development with proper git workflows and clean code to "vibe coding" has eroded professional standards and made the work more frustrating.

    picknplace.js

    A proof of concept for an alternative to drag-and-drop interactions that uses a two-step "pick then place" approach. Instead of dragging items, users first pick an item, which creates an interactive duplicate list overlay, then place it in the desired position. The approach aims to solve usability issues with traditional drag-and-drop, particularly on mobile devices where tapping, holding, dragging, and scrolling simultaneously is awkward and error-prone.
