    Choosing the Right RPC Framework for .NET

    This story was originally published on HackerNoon at: https://hackernoon.com/choosing-the-right-rpc-framework-for-net. WitRPC vs SignalR vs gRPC vs CoreWCF: measured benchmarks, transports, serialization and Blazor support, with an open-source benchmark suite.

Learn more about this writer by checking @dmitrat's about page, and for more stories, please visit hackernoon.com. I benchmarked four RPC options for .NET on the same hardware and the same intercontinental network path, then compared them on developer experience, transports, serialization, discovery, and Blazor/AOT support. WitRPC led both benchmark sets; gRPC was four times slower on large unary payloads; SignalR stayed strong for browser fan-out; CoreWCF is a migration path rather than a new-project choice. The benchmark suite is open source, so every number can be reproduced or refuted.

    Why * Doesn't Create Independent Nested Lists in Python (The Hidden List Multiplication Trap)

    This story was originally published on HackerNoon at: https://hackernoon.com/why-doesnt-create-independent-nested-lists-in-python-the-hidden-list-multiplication-trap. Learn why [[0,0,0]] * 3 in Python secretly shares one list across all rows, and how to build truly independent nested lists the right way. Check more stories related to programming at: https://hackernoon.com/c/programming. You can also check exclusive content about #python, #python-programming, #python-lists, #python-shared-references, #python-mutable-objects, #python-list-comprehension, #mutable-list-bug-in-python, #hackernoon-top-story, and more. This story was written by: @sohelalam79. Learn more about this writer by checking @sohelalam79's about page, and for more stories, please visit hackernoon.com. [x] * n does not create n independent copies of x. It creates one object and repeats a reference to that same object n times. For immutable elements like numbers or strings, this is harmless because any "change" actually rebinds the slot to a new object. For mutable elements like lists or dicts, every slot points to the exact same object, so mutating one slot mutates all of them. The fix is to use a list comprehension — [x for _ in range(n)] — which creates a genuinely new object on each iteration. Key takeaway: * repeats references, not values.
