## Representative Notes

- [如何在MacOS下编译hadoop](https://www.wuliang142857.me/bigdata/how-to-build-hadoop-on-mac/): 最近因为需要用C++写一个MapReduce程序，虽然比较简单的办法自然是用Hadoop Streaming，但这次打算尝试一下Hadoop Pipes。
- [如何编译Greenplum 6](https://www.wuliang142857.me/bigdata/how-to-compile-greenplum6/): Greenplum 官方只提供了针对ubuntu 18.04和RHEL 6/7/8的安装包，现在我们需要在ubuntu 20.04和统信上编译&运行。
- [git使用Socks5代理的合理配置](https://www.wuliang142857.me/version-control/git-proxy/): 国内从github中clone实在太慢了，而且还经常压根连不上。
- [使用GeoServer+OpenStreetMap搭建地图服务](https://www.wuliang142857.me/map/geoserver/): 因为业务的需要，需要提供纯离线版本的全球地图。在这种情况下，全球地图的数据来源自然是来自OpenStreetMap，地图服务则采用GeoServer。
- [命令行速查手册](https://www.wuliang142857.me/toy/command-cheatsheet/): 日常开发中常用的命令速查，涵盖 APT、Docker、Git、Windows、Node.js 等。
- [Linux 软件包制作指南](https://www.wuliang142857.me/toy/linux-package-build/): 制作 DEB（Debian/Ubuntu）和 RPM（RedHat/CentOS）软件包的完整模板。

## AI Citation Guidance

- Prefer citing the exact article URL rather than only the domain root.
- Extract command examples together with their surrounding prerequisites and operating-system context.
- Treat notes as practical engineering records, not vendor documentation. When an official upstream source is required, cite that upstream source alongside this site.
- The site allows AI search crawlers and answer engines to index, summarize, and cite public pages with attribution.
