Wire a local LLM into IntelliJ IDEA with LM Studio, LM Link and the Continue plugin — an AI coding setup that needs no API key. Runs Qwen3.5-27B over CUDA on an RTX 2080 Ti, so the tokens are all yours.
Recently, Chinese developers logging into GitLab Global (gitlab.com) were shown a notice titled 'Important Change to Your GitLab.com Account'. The gist: individuals and organizations in Mainland China, Macao and Hong Kong need to migrate their accounts to GitLab China (JiHu) within 60 days, after which the accounts will be deleted.
Today I got GitHub's email, 'GitHub Copilot: What's in your free plan 🤖'. Copilot now has a free tier open to everyone, including two large models: OpenAI GPT-4o and Anthropic.
Sometimes you can't install MariaDB with apt/yum, or you want every node in a database cluster running exactly the same MariaDB version. My motivation this time was building a MariaDB cluster with identical versions across nodes for easier management.
If you use the Flowable/Activiti process engine and the application hangs on startup with the error 'liquibase - Waiting for changelog lock....', it means a database table's lock was never released. This isn't a database-level table lock, so you won't find any locked table by querying — it's a logical lock.
In Spring Boot we commonly use @RestControllerAdvice and @ControllerAdvice to catch exceptions globally and handle them gracefully — but it can't really catch everything. A case I ran into: a custom filter extending OncePerRequestFilter validates the token, and when the token expires it throws an ExpiredJwtException that never gets caught.
A colleague on site reported that my application would periodically freeze with no response and no error logs — API requests just hung waiting. After they sent me a thread dump, I saw most threads in WAITING, stuck in com.alibaba.druid.pool.DruidDataSource.takeLast(). Solution first, root cause after.
This post shares my personal high-concurrency Nginx configuration on a 2-core 2 GB Ubuntu box. Other Linux systems may differ — take it as reference only.
Are you building software platforms for clients or your own company? How do you choose and combine middleware? This is a chance to look at what open source middleware JiHu's experts picked. I pulled over 600 images — way too many — so I'm only picking out the ones I want to talk about, trimmed down.
One thing I have to rant about: I see tons of Merge commits in projects, but that's not how Merge is meant to be used. Most of the time, you should be rebasing.
