Why do most devs still rely on resumes & LinkedIn - when neither was built for us?
Came across this article and it got me thinking... We have portfolios. Repos. Side projects. Blog posts. But 90% of the hiring pipeline still revolves around resumes and LinkedIn - tools that werenβt built for how devs actually work or show skills. I personally got 10x more traction in job applications after ditching my resume and sending a personal micro-site + short video walkthrough of my work. That landed me a Big...

Developers love mocking. Itβs been a go-to solution for years: Simulate external services, run tests faster, and avoid the overhead of real APIs. But hereβs the truth β mocking is overused and often dangerous. It deceives you into thinking your system is stable, hiding critical failures that only appear when your code hits the real world. APIs change. Rate limits throttle you. Authentication flows break. Your tests...
