AMQP Error: connect ECONNREFUSED ::1:5672

在 Mac 上用 Node.js 连接 RabbitMQ 时，localhost 被解析成 IPv6 的 ::1，而服务只监听 127.0.0.1，改成 127.0.0.1 或修正 hosts 后恢复。

On a Mac, Node.js resolved localhost to IPv6 ::1 while RabbitMQ listened only on 127.0.0.1. Switching the host or fixing /etc/hosts resolved it.

could not execute statement; SQL [n/a]; constraint [null];

测试环境出现 Hibernate ConstraintViolationException。原因是开发库把某字段改成可空后，未同步到测试库，同步后问题解决。

A Hibernate ConstraintViolationException in the test environment came from a nullable-column change that had not been synced from the development database.

一道合并数组算法题引发的血案

面试时被要求在十分钟内写出合并 n 个有序数组，现场没写完。事后记录了双指针、从后往前合并，以及两两归并的解法。

A merge-n-sorted-arrays interview prompt went unfinished in ten minutes. The write-up covers two-pointer merging from the tail and pairwise merging.

Not able to find Java executable or version

启动 JMeter 5.3 报找不到 Java 可执行文件。JAVA_HOME 路径含空格，后来用 java -jar ApacheJMeter.jar 直接启动解决。

JMeter 5.3 failed to find the Java executable, partly because JAVA_HOME contained a space. Launching with java -jar ApacheJMeter.jar worked.

IDEA 如何实现对远程服务器代码进行 debug 操作

同一段代码在本地和开发服务器正常、测试服务器报错。记录了给远程 Jar 加 JDWP 参数，再在 IDEA Remote 里对接调试的步骤。

The same code failed only on the test server. The note documents adding JDWP options to the remote Jar and attaching IntelliJ’s Remote debugger.

落枕做理疗的时候想，朱自清他爸可能也是因为落枕了🤔

就这么听着歌，看完一本小说，无所事事也挺好。要是不感冒就更棒了😏

像《东京八平米》里面描述的一样，第一次体验🤓

多喝咖啡！

健康数据

Health Data

之后会在这里展示来自 Apple Watch 的汇总数据（步数、心率、睡眠等），不包含精确时间与位置。页面会读取 /data/health.json。

This section will later show Apple Watch summary data (steps, heart rate, sleep) without precise timestamps or location. The page reads /data/health.json.

还没有健康数据。接入后，把汇总结果放到 data/health.json 即可在这里显示。

No health data yet. Once connected, place summary data in data/health.json to display it here.
