How can I send large messages with Kafka (over 15MB)?
...
Yes. On the consumer side, you allocate fetch.message.max.bytes memory for EACH partition. This means that if you use a huge number for fetch.message.max.bytes combined with a large number of partitions, it will consume a lot of memory. In fact, since the ...
How do I tokenize a string in C++?
...ybe, but then we’re forced to perform (potentially redundant and costly) allocations.
Instead, C++ offers a plethora of ways to split strings based on arbitrarily complex delimiters, but none of them is encapsulated as nicely as in other languages. The numerous ways fill whole blog posts.

count vs length vs size in a collection
... - check source/documentation.
Capacity() - used to specifically refer to allocated space in collection and not number of valid elements in it. If type has both "capacity" and "size" defined then "size" usually refers to number of actual elements.

What is a segmentation fault?
...s doesn't happen always (with gcc being one of this compilers). Also, the allocated stack space is normally reused again, so I have heard of no operating systems that return unused stack pages to the system, making that space subject for a SIGSEGV, so I won't expect such a signal from mangling with...
What is string_view?
...or increasing the efficiency by avoiding unneeded copies (think of all the allocations and exceptions you can save).
The original C strings were suffering from the problem that the null terminator was part of the string APIs, and so you couldn't easily create substrings without mutating the underly...

Heavy usage of Python at Google [closed]
... C++ and they spend 10% of their time tracking down bugs related to memory allocation, guess who's done faster - even if the C++ shop manages to write the rest of their code just as fast.
So yes, I'd say it is a competitive advantage to code in Python.
