GitLab has notified users that it will stop serving accounts in Mainland China, Hong Kong and Macao, and plans to delete those accounts after September 7, 2026. If you got the email, back up your code, project data and CI configuration as soon as possible.
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.
On December 3, 2024, Cloudflare updated its 'Cloudflare Self-Serve Subscription Agreement', explicitly banning IP cherry-picking (deliberately selecting specific Cloudflare edge IPs) and building proxies (circumvention tunnels) on its platform.
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.
In Spring projects we often use maven variables to switch environments — for example the @activatedProperties@ placeholder in this post, passed in at maven packaging time so the config file can switch between runtime environments.
What's a cron expression? If you're reading this, you probably already know what it's for: when setting up scheduled tasks on Linux, Spring or Quartz, you write a cron expression to define the execution cycle. Cron is pronounced /krɒn/ — like 'chron' in chronology.
GitHub now scans public and private repositories for WeChat keys and tokens — including those for WeChat Official Accounts, Mini Programs, and WeChat Pay — and forwards them to Tencent. You'll get a key leak notification on Tencent's side.
