Production Incident
Reading Time: < 1 minute Had a production incident recently after production deployment. I was not intimately familiar with the oracle index charge (drop) and impact on other apps (lack of visibility and lack of perf testing environment).

Keep fit
Reading Time: 2 minutes I am trying to keep fit and I have been doing this for a while (before pandemic). This includes both the physical fit, weight and most recently, the iPhone addiction.

Tech Layoffs and don’t lose faith
Reading Time: < 1 minute The tech sector started layoff, hiring freeze or internal move freeze (Amazon came to mind) recently. My worst memory on layoff was on Oct 11, 2001.

In recent years, the platform has expanded… Continue reading Twitter
Alternatives to Facebook, LinkedIn and Twitter
Reading Time: < 1 minute The three legacy social networks 🙂 I have been using the 3 for a while, since 2008 to be precise. I started using LinkedIn after I switched job in Nov 2008 (amid financial crisis), because I realized I want to look for a developer job quickly after I jumped ship. I cannot remember the reasons… Continue reading Alternatives to Facebook, LinkedIn and Twitter

My cars over the years
