A compiler for a language with generic types will definitely do less work to implement generic min/max than the C preprocessor has to do in order to perform all the text substitutions generated by these macros.

They do not address the question at all. Please write an answer yourself.

C codebases can often be updated with minor changes to compile with a C++ compiler, after which C++ features can be gradually introduced. Is the Linux kernel different in this regard?

Can someone explain the benefit of having essentially 4 cores (2 ARM + 2 RISC-V) on the chip but only having 2 able to run simultaneously? Does this take significantly less die space than having all 4 available at all times?

That series of macros is a nice demonstration of the incredible effort it takes to attempt the most basic generic programming in C. Perhaps it would be more productive to just accept the limitations of the language and define a version of `

Just curious, what kind of embedded system were you working on that required arbitrary precision numbers, and where it was acceptable for the system to stall for 40 seconds during a calculation?

Those are definitely not the same question, NP-hardness has a precise meaning while "hard to solve" is a subjective judgement The answer is trying to show the absurdity of the question. It's like asking for the time complexit

You have misunderstood the article. The question being discussed was not "How hard is it to solve P?=NP", it was "Is P?=NP itself NP-hard", which is just an invalid question.

Feeding birds will only lead to rats if you give them the wrong food or too much. Otherwise they will eat it all up and there will be nothing left for the rats.

That's correct. The resulting error message won't be a stack trace, but I find it spells out the problem quite nicely in practice. I haven't had issues with grepping for the errors, but I can see that it would be a problem in

Since the prompt doesn't mention error handling explicitly, it does show a difference in the general attitude towards error handling in the Python code vs. the Go code in the corpus
134.
by jonathrg 3y ago
It's generally good practice to not just `return err`, but to `return fmt.Errorf("some context: %w", err)`. That's usually enough for you to get what you need, with a much higher signal-to-noise ratio than a stack trace.

Those libraries should not have named the methods like that. They could have chosen any naming scheme and they went with something that collides with the only naming scheme available to Python itself

A decorator is a function that takes a function and returns a modified function - how would you write a decorator without nesting functions? Wrapping the inner function of the decorator with @wraps is quite common - one might consider it a

> A ring oscillator in an FPGA can be used as a strain gauge. If you implement a ring oscillator on an FPGA and then bend the FPGA, the frequency of the ring oscillator will shift. That's horrifying. I love it.

There is a standard for these kinds of things, the IEC-80000 part 13 defines quantities related to information science and technology. The one that is closest to request rate is probably "call intensity / calling rate". http

In case anyone else was wondering if this was an acronym for an aphorism (like YAGNI), this is an error code (error text busy). And 'text' refers to the executable

Indeed. Typically you have pairs of call and ret, where call creates a stack frame and ret tears it down caller caller | ^ (call) . . . . . . . . . . . . . (ret)

This is because of the calling convention / ABI If you write void free_with_extra_args(int *a, int *b) { free(a); } then *a is in already in the correct slot (the RDI register) for the first argument when free_with
