The entire organization can be commanded up and down through the mysterious API department. It speaks multiple official languages: REST API and GraphQL API. We'll start with REST. Before we begin, we need to apply for a token on JH GitLab — only a valid token lets you issue commands to this mysterious API department.
You're so eager to learn, fine, I'll tell you: our JH GitLab association can audit vulnerabilities for you too. In the Security Hall there are security masters who can scan the manual you wrote, covering Static Application Security Testing (SAST), Infrastructure as Code (IaC) scanning, Dynamic Application Security Testing (DAST), dependency scanning, container scanning, and more.
Xiaobai was strolling around JH GitLab when he ran into the Chief again and hurriedly stopped him: you said you'd teach me Docker cache optimization last time, tell me now. Chief: fine, you're eager to learn. Do you know our JH GitLab association has a Package Warehouse for managing artifacts? Xiaobai: of course, I've just never used it. How does it work?
Xiaobai has been wandering the jianghu for years. He heard that the leader of the Tianxia Hui is unmatched in martial arts, his Three-Part Return-to-Origin Qi (DevOps, DevSecOps, GitOps) invincible under heaven. One day he saw that JH GitLab Tianxia Hui was sending out hero invitations, recruiting Jihu heroes to join the internal testing hall and start training.
To understand why Optional exists, you first need to understand NPE. Many object-oriented languages have a null value: a pointer on the stack that points at a heap address that doesn't exist. Use that object and you get a NullPointerException. If you fail to anticipate the null case, your program crashes.
GitLab didn't disappoint me, but it didn't wow me either — it's the straight-A student, solid but predictable. There's almost no localization, so no pleasant surprises: powerful features, steep learning curve, incomplete Chinese translation. JiHu still has a long way to go on localization.
In software design and development you can't avoid dealing with text. A designer hands over a mockup, the developer eyedroppers the color and hardcodes it — then the day you change the theme or background, the result is horrendous. Here's what I've learned about text color.
Tired of domestic databases shipping no macOS installer while doing localization work? This tutorial runs Kingbase V8 R3 (a Chinese domestic database) in a Docker container on macOS, giving your MacBook a working Kingbase development environment.
This tutorial walks you through creating a custom Apache NiFi Processor project and writing your own processor to handle FlowFiles. Source code: https://github.com/renfei/demo/tree/master/nifi/nifi-custom-bundle
I previously wrote "The Big Pitfall of Reading Files After Packaging a Spring Boot Project Into a Jar: ClassPathResource Fails to Read Files on the Classpath" and published it on my blog and CSDN. I hadn't logged into CSDN in a long while; today I did, and found two commenters both saying they tried my approach and couldn't get anything.
