  PHP: a fractal of bad design

Preface I’m cranky. I complain about a lot of things. There’s a lot in the world of technology I don’t like, and that’s really to be expected—programming is a hilariously young discipline, and none of us have the slightest clue what we’re doing. Combine with Sturgeon’s Law, and I have a lifetime’s worth of stuff to gripe about. This is not the same. PHP is not merely awkward to use, or ill-suited for what I want, or suboptimal, or...

  Go Error Best Practice

Being indulged in Go for quite a while and having implemented web-related programs, grpc interfaces and Operators, I seem to be an advanced beginner now. However, I am still a raw hand in production-environmental debugging, which is cumbersome if done by querying logs or error messages. Imagine the scenario that a full-text search is called when the specific location of the error log is missing. Then what happens when those error logs are not only in one place? Yes, my error logs can no longer h...

  The Problem With Client-Side Analytics

Client-side analytics is broken. The numbers produced by it are trivially spoofable by competitors and nefarious characters. Most websites use client-side analytics of one type or another and the only way to get numbers you can trust is to compare numbers from multiple providers and to take an average of the closest two.This post highlights the problem and proposes a partial solution that substantially mitigates the issues with minimal effort. Our proposed solution is simply to include a digital...

  The First Bite on etcd Code

Etcd, one of the crucial components of Kubernetes. If APIServer is the heart, then etcd is the blood vessel that sends the end state of Kubernetes resources to various “organs”, providing high-speed, stable storage, and supporting APIServer’s high load performance. What if the etcd is not working properly? Just the condition as someone has a vascular disease. The deeper you know about them, the better diagnose you can make when issues occur. from unspl...

  A Sip of Go Log

Logging is indispensable in any code that we need its support both in debugging and in statistics. However, a package that filled withfmt.Println/fmt.Printf printing various messages can never be considered a read-to-be-adopted package, which can be optimized by a simple change, using Golang’s native log package to print information to standard output or to a file. Then, how to apply the log package? Are there any limitations? If so, can we seek open-source packages? Let&rsq...
