Using eSIMs on Devices with Only Physical SIM Slots: A 9eSIM Review

2025-01-20

This blog post details using a 9eSIM SIM card to enable eSIM functionality on devices that only accept physical SIM cards, tested on Android and Linux. The author purchased a 9eSIM bundle including the SIM, smartcard reader, and adapter. Initial setup proved slightly tricky, requiring the SIM card to be used within its original packaging for proper reader connection. Adding, switching, and deleting eSIM profiles was straightforward using an Android app or the Linux command-line tool lpac (and its GUI, EasyLPAC). Tests were conducted with free test eSIM profiles and a paid LycaMobile eSIM, successfully achieving eSIM connectivity on a Debian Linux laptop.

Go's Error Handling: A Blessing or a Curse?

2025-03-09

Go's error handling, characterized by the ubiquitous `if err != nil` check, has sparked considerable debate. Critics find it verbose and cumbersome, while proponents argue it's a cornerstone of Go's philosophy, treating errors as first-class citizens. This article delves into the pros and cons, comparing Go's approach to exception handling in languages like JavaScript. It highlights best practices, such as creating actionable error chains using `fmt.Errorf` and leveraging libraries like `github.com/pkg/errors` for enhanced clarity and stack traces. While not without flaws, Go's explicit error handling empowers developers with full control over program flow, emphasizing simplicity and proactive failure planning.
