There is no infinite loop. If the dictionary is a string, it is simply skipped. If all dictionaries are strings, than all elements of the finite list are skipped, and the function returns without...
The quick fix is: map (subtract 1) . take n $ l When I put your function in my own Haskell compiler, I get: Possible cause: ‘take’ is applied to too many arguments Remember that in Haskell,...
Temporary notice: this is part of an ongoing project of transferring and splitting my canonical from Stack Overflow on common errors in Google Apps Script. As soon as the Q&As are finalized, ...
I have a function that loads JSON data and is declared to return a dictionary with string keys and values of any type (Dict[str, Any]). However, mypy is raising an error stating that I am returning...
As this is the first question about Google Apps Script, here is a very brief description: it is a platform that helps people easily get programmatic access to Google apps data like Gmail messages, ...
There are some reasons why a function would intentionally not be declared static. (In the following I use the term 'module', but in contrast to others, I use it not to describe a file or translati...
I noticed when attempting to generate random booleans that t and f are not treated in the same way: t random ! Error f random ! returns a value In the factor 0.98 and 0.99 documentation, t is ...
The answer is indicated on the page for f. Specifically, "[t]he f object is the singleton false value, the only object that is not true." In contrast, t is defined simply as SINGLETON: t where SING...
I don't think GNU can be used as a stand-alone tag. Apart from the OS, GNU is also a tool collection of various programs, many used for programming, making is a very ambiguous tag which can't stan...
I'd like to assert that some code can be optimized out, and is not present in the final binary object. #define CONSTANT 0 #if (!CONSTANT) [[landmine_A]] #endif static int foo(void); void...
Yes it is fine and probably encouraged even. I have written several self-answered Q&A here and they were mostly well-received. They aren't all that easy to write though, especially getting the ...
Well, you still need (placement) new for the implementation of the smart pointers themselves. You would also use it (or malloc) to implement custom allocators, for example: https://www.boost.org/d...
Apparently this is controlled by the registry value Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\NuGet\Repository\UWPNugetPackages. I changed it from C:\Program Files (x86)\Microsoft SDKs\UWPNu...
Is it undefined behaviour to cast an uninitialized variable to (void)? Example: int main() { int x; (void)x; return 0; }
If you want a table for including in a latex document, then DataFrame.to_latex should be the best way. import pandas as pd import numpy as np df = pd.DataFrame(np.random.rand(9, 4), columns=['a'...
One possibility with axvline: import pandas as pd import numpy as np import matplotlib.pyplot as plt df = pd.DataFrame(np.random.rand(9, 4), columns=['a', 'b', 'c', 'd']) df.plot.bar() plt....
MWE import pandas as pd import numpy as np import matplotlib.pyplot as plt df = pd.DataFrame(np.random.rand(9, 4), columns=['a', 'b', 'c', 'd']) df.plot.bar() plt.show() Question Ho...
Update: Distinguished between the general case and cases (as with std::string) where it is known that there are no side effects. In the general case, the substitution of the call to a copy constru...
If you have a class which needs to store a construction parameter internally, and you want to take advantage of move semantics, I understand that the parameter should be passed by value: class Foo...
It is undefined according to my reading of the standard (I am referring to the latest public draft). int x; (void)x; In the second line, (void)x is a full expression, but x by itself is alread...
Summary I'm refactoring a Rust-based service/daemon to move away from gRPC and use a Rocket-based API instead. I'm also using the daemonize crate to turn the foreground process into a background p...
Starting with the goals: A naming convention typically aims at supporting several, partly contradictory goals, among which are the following: Compliance with the limitations of the language stan...
There are two things going on here. One which technically explains what's going on fully, and another potential misconception you have. For the former, &T implements the Copy trait regardless ...
Context I noticed that an application was flooding the database with simple SELECTs. The investigation revealed some bugs in the health check which theoretically implemented caching (to avoid quer...
Hello everyone, I am seeking help with understanding why multithreading does not work correctly in this example: import time import matplotlib.pyplot as plt import concurrent.futures voltage...
