            spec_tbl_df is over 10 times slower on same opperations as a normal tibble
            Asked 2021-Jun-15 at 14:37

            So I was really ripping my hair out why two different sessions of R with the same data were producing wildly different times to complete the same task. After a lot of restarting R, cleaning out all my variables, and really running a clean R, I found the issue: the new data structure provided by vroom and readr is, for some reason, super sluggish on my script. Of course the easiest thing to solve this is to convert your data into a tibble as soon as you load it in. Or is there some other explanation, like poor coding praxis in my functions that can explain the sluggish behavior? Or, is this a bug with recent updates of these packages? If so and if someone is more experienced with reporting bugs to tidyverse, then here is a repex showing the behavior cause I feel that this is out of my ballpark.

            This is the issue I had in mind. These problems have been known to happen with vroom, rather than with the spec_tbl_df class, which does not really do much.

            vroom does all sorts of things to try and speed reading up; AFAIK mostly by lazy reading. That's how you get all those different components when comparing the two datasets.

            I want a function that takes two arguments, both of which can be turned into an iterator of Foo. The snag is that I'd like to accept things which are both IntoIterator and also IntoIterator<&Foo>. Importantly Foo is Copy so I can cheaply create an owned copy from it's reference.

            Is it legal for a compiler to ignore an #include directive?
            Asked 2021-Jun-13 at 14:30

            As I understand, when compiling a compilation unit, the compiler's preprocessor translates #include directives by expanding the contents of the header file1 specified between the < and > (or ") tokens into the current compilation unit.

            It is also my understanding, that most compilers support the #pragma once directive guarding against multiply defined symbols as a result of multiple inclusion of the same header. The same effect can be produced by following the include guard idiom.

            My question is two-fold:

            1. Is it legal for a compiler to completely ignore an #include directive if it has previously encountered a #pragma once directive or include guard pattern in this header?
            2. Specifically with Microsoft' compiler is there any difference in this regard whether a header contains a #pragma once directive or an include guard pattern? The documentation suggests that they are handled the same, though some user feels very strongly that I am wrong, so I am confused and want clarification.

            1 I'm glossing over the fact, that headers need not necessarily be files altogether.

            ANSWER

            Answered 2021-Jun-13 at 08:31

            It the compiled program cannot tell whether the compiler has ignored a header file or not, it is legal under the as-if rule to either ignore or not ignore it.

            If ignoring a file results in a program that has observable behaviour different from a program produced by processing all files normally, or ignoring a file results in an invalid program whereas processing it normally does not, then it is not legal to ignore such file. Doing so is a compiler bug.

            Compiler writers seem to be confident that ignoring a once-seen file that has proper include guards in place can have no effect on the resulting program, otherwise compilers would not be doing this optimisation. It is possible that they are all wrong though, and there is a counterexample that no one has found to date. It is also possible that non-existence of such counterexample is a theorem that no one has bothered to prove, as it seems intuitively obvious.

            Get C FILE pointer from bytes::Bytes in Rust
            Asked 2021-Jun-12 at 13:29

            I would like to read a GRIB file downloaded from server using ecCodes library in Rust. However, my current solution results in segmentation fault. The extracted example, replicating the problem, is below.

            I download the file using reqwest crate and get the response as Bytes1 using bytes(). To read the file with ecCodes I need to create a codes_handle using codes_grib_handle_new_from_file()2, which as argument requires *FILE usually get from fopen(). However, I would like to skip IO operations. So I figured I could use libc::fmemopen() to get *FILE from Bytes. But when I pass the *mut FILE from fmemopen() to codes_grib_handle_new_from_file() segmentation fault occurs.

            I suspect the issue is when I get from Bytes a *mut c_void required by fmemopen(). I figured I can do this like that:

            When x = 10³⁰, y = -10³⁰ and z = 1, why do (x+y)+z and x+(y+z) differ?
            Asked 2021-Jun-11 at 11:28

            What Every Computer Scientist Should Know About Floating-Point Arithmetic makes the following claim:

            Due to roundoff errors, the associative laws of algebra do not necessarily hold for floating-point numbers. For example, the expression (x+y)+z has a totally different answer than x+(y+z) when x = 1030, y = -1030 and z = 1 (it is 1 in the former case, 0 in the latter).

            How does one reach the conclusion in their example? That is, that (x+y)+z=1 and x+(y+z)=0?

            I am aware of the associative laws of algebra, but I do not see the issue in this case. To my mind, both x and y will overflow and therefore both have an integer value that is incorrect but nonetheless in range. As x and y will then be integers, they should add as if associativity applies.

            Round off error, and other aspects of floating point arithmetic, apply to floating point arithmetic as a whole. While some of the values that a floating point variable can store are integers (in the sense that they are whole numbers), they are not integer-typed. A floating point variable cannot store arbitrarily large integers, any more than an integer variable can. And while wraparound integer arithmetic will make (a+b)-a=b for any unsigned integer-typed a and b, the same is not true for floating point arithmetic. The overflow rules are different.
