  Different types of keystore in Java -- JCEKS

JCEKS stands for Java Cryptography Extension KeyStore and it is an alternative keystore format for the Java platform. Storing keys in a KeyStore can be a measure to prevent your encryption keys from being exposed. Java KeyStores securely contain individual certificates and keys that can be referenced by an alias for use in a Java program.

  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...

It’s the kind of feature you rarely need, and then suddenly, one day, you find yourself in dire need of it, as evidenced by the real-life use-case below. If you don’t know what a function pointer is in the first place, here’s the meat of it: it gives you the ability to pass a function around like a normal variable. If you know Python / Ruby / Lisp, you might know it by the name...

  How To Write A Good Programming Test

I’ve taken and marked a lot of programming tests in the past. I love doing them as it’s always good to see what challenges different programmers have come up with when designing them. Unfortunately, however, most of them aren’t very good. Below is a list of general ideas to help increase the quality of programmer tests. 1. Keep it relevant Too many of the tests have questions on content that simply isn’t relevant to the job. The whole idea behind a programming test i...

  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...
