Top 7 Static Code Analysis Tools

DZone

What Is a Static Code Analysis? Static code analysis or Source code analysis is a method performed on the ‘static’ (non-running) source code of the software with static code analysis tools that attempt to highlight potential vulnerabilities. Why Use Static Analysis? Executes quickly compared with dynamic analysis. Now that we are aware of static code analysis, we must know the tools that are already leading the market.

Reimagining Experimentation Analysis at Netflix

The Netflix TechBlog

With our new platform for experimentation analysis, it’s easy for scientists to perfectly recreate analyses on their laptops in a notebook. The analysis reports tell us whether or not a new experience made statistically significant changes to relevant metrics, such as member behavior, or technical metrics that describe streaming video quality. Now scientists can easily introspect the data and extend it in an ad-hoc analysis.
