push gateway
Overview Occasionally you will need to monitor components which cannot be scraped. The Prometheus Pushgateway allows you to push time series from short-lived service-level batch jobs to an intermediary job which Prometheus can scrape. Combined with Prometheus’s simple text-based exposition format, this makes it easy to instrument even shell scripts without a client library. Data […] →Read more
Prettier for java
Overview Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary. A Prettier plugin must first parse the source code of the target language into a traversable data structure (Usually an […] →Read more

cloud native buildpacks
Cloud Native Buildpacks (CNBs) transform your application source code into container images that can run on any cloud. With buildpacks, organizations can concentrate the knowledge of container build best practices within a specialized team, instead of having application developers across the organization individually maintain their own Dockerfiles. This makes it easier to know what is […] →Read more
打包保护你的 Python 程序
1. 编译成可执行文件 可以使用工具将 Python 脚本转换为独立的可执行文件： 工具： PyInstaller: 支持多平台（Windows、macOS 和 Linux）。 pyinstaller –onefile your_script.py 上述命令会生成一个单独的可执行文件，位于 dist/ 目录下。 cx_Freeze: 也是一个常用的工具，支持类似功能。 cxfreeze your_script.py –target-dir dist/ py2exe（Windows 专用）: 将 Python 脚本编译成 Windows 下的可执行文件。 优点： 生成的可执行文件不需要 Python 环境即可运行。 部分情况下可以混淆或隐藏源代码。 缺点： 用专业的反编译工具可能仍然还原部分代码逻辑。 2. 字节码保护 Python 源代码在运行时会被编译成字节码文件（.pyc），可以通过生成 .pyc 文件分发代码： 使用 compileall 模块生成字节码文件： python -m compileall your_script.py 然后分发生成的 .pyc 文件。 配合工具如 cython 或 […] →Read more
