Gartner’s Recommendations for DevOps Pipeline Success Icon

Is your CI/CD pipeline a hodge-podge of randomly connected tools?

Gartner’s Recommendations for DevOps Pipeline Success Icon
You’ve likely added a tool to fix one problem and then a different tool to fix another problem. Pretty soon you have multiple instances of the same tool, different tools with overlapping functionality, no ability to collaborate across teams—all resulting in unknown bottlenecks and complicated or no reporting. As a DevOps leader, it’s up to you to balance the autonomy and flexibility of a DevOps approach. But how?

    I tried to use this to alleviate numerical stability issues with some matrix computations. However using Big<1,2> instead of double turns fraction-of-a-second computation into multi-hour computation (or more, I stopped the computation after a couple of hours). I also found out that a lot of standard operators are missing, e.g.: Big operator*(double, Big) Big operator*(int, Big) etc... even though operators involving only Big type are implemented, e.g.: Big operator*(Big, Big). Strangely, Abs(), Sqrt() etc do not work on a copy but on the parameter itself, thus instead of Big positiveA=A.Abs(); the following code is required: Big positiveA=A; positiveA.Abs(); Lastly, casting to int doesn't work: int(Big) //compile error //http://www.learncpp.com/cpp-tutorial/910-overloading-typecasts/ Bottom line: For some less computationally demanding scenarios, I guess this class is useful.
