We explain Pysa, a static analysis tool to detect and prevent security issues in Python code. Pysa alerts the software engineers or security engineers so they can fix the bug before the code change is ever merged into the codebase.
Tools
- Pysa: a static analyzer which means it can analyze code without needing to run it. If Pysa does detect that the source connects to the sink, it will report an issue.
We explain Infer, a static analysis tool for programming languages like Java and C.
Tools
- Infer: a static analysis tool used to detect bugs in programming languages. Infer catches Null Pointer exceptions, race conditions, memory leaks and other defects early in the project lifecycle.
We explain Watchman, a file watching service. Watchman allows developers to focus on managing the files they worked on in the web app development process with incremental build.
Tools
- Watchman: uses with clients for a command line, NodeJS and more. It records any changes and triggers assigned actions.
We explain Hack, a programming language focused on productivity and type safety. Hack can stay speedy by incrementally type-checking your files as you edit them.
Tools
- Hack: Provides engineers with quick feedback loops to develop faster while keeping safety in mind with static typing.
We explain Flow, a static type checker for JavaScript. Flow checks your program in the background while you concentrate on writing quality code and reports errors back to you.
Tools
- Flow: A static type checker for your JavaScript code. Flow checks your code for errors through static type annotations. These types allow you to tell Flow how you want your code to work, and Flow will make sure it does work that way.
With every new release version, PyTorch pushes out new features, updates existing ones, and adds documentation and tutorials that cover how to implement these new changes. Check out a behind the scenes look at how the team planned and deployed an overhaul of the PyTorch tutorials portal.
