There is an external program I'm calling from within my C/C++ program, by using fork() and execl(), and redirecting the stdio with dup2() to be able to read the output from the external program. I...
In my opinion, all of the downsides boil down to two objections: It isn't idiomatic (in C# and VB.NET) It's slightly less performant The fact that it isn't idiomatic means that, as you note...
Before we start, I'd like to be a little bit pedantic regarding 00002451018 being a number. When we talk about numeric types/values, the zeroes at the beginning are irrelevant: 2, 02 and 000002 al...
I have recently stumbled across the Maybe (or Optional) modal usage in .NET Code: example code or this one example article Based on everything I read, there are multiple advantages on relyi...
From the Git docs "reset" copies the old head to .git/ORIG_HEAD To restore that commit, you can run $ git reset ORIG_HEAD If you want to restore more than one reset, then you'll have to l...
Let's consider the following code: const char a[][4] = {"aa", "aaa"}; const char *b[] = {"bb", "bbb"}; const char *const c[] = {"cc", "ccc"}; For shared libraries, both b and c arrays require...
Context This Q&A from SO suggests that throwing exceptions is incredibly expensive when compared to returning values (return codes): that with return codes instead of exceptions the same pr...
Ignoring the numerous forms of undefined behavior that casting away const might invoke, the blunt but simple and standard solution is just to cast to (void*). char* foo (const char* str) { r...
Hello. Total noob here and noob to this site. I've written a non-trivial program in Python. Code review didn't take the whole thing (400+ lines of code). Should I post a link to my Github repo ...
I'm actually mainly interested in testing foo() Ok, so let's do that. I could make it public, but I really don't want to do that just so that the test class can access it Java has 4 diff...
Unfortunately I think the simple answer is that you cannot do what you want with standard Vim (or NeoVim, which I also tested — although NeoVim is slightly more convenient in that you don't need to...
Background This is kind of a subquestion to How to properly use malloc? When allocating, there are basically two common ways of using the sizeof operator: int *p; p = malloc(n * sizeof *p); /...
I've created a function that calls scanf passing a void pointer as argument: void read(const char *format, void *p) { scanf(format, p); } And tested it with different types: int n; read...
While writing the question I actually came up with something that seems to work fairly well, and it's very simple. Just add if(false) in front of the statement.
(This answer became more ORM v. "direct" SQL. If you're very narrowly focused on just stored procedures, then it's not super important to me that the logic be packaged up in stored procedures. That...
Actually, while REST mandates a great many things, it does not constrain the structure of URLs. To wit: The paper that coined the term "REST" describes resource identifiers as black boxes, and make...
A person I used to work with several years ago was hired to rewrite a product using a .NET-based modern tech stack. One of the aspects that stroke me was that he believes that the product should mo...
In Vim, it's possible to tell it to read from stdin instead of a file, by using vim -. This is so that you can pipe the output of one command into Vim, to view/edit it there. The problem I'm facin...
Why object-oriented instead of class-oriented? tl;dr Because you can "do OOP" without classes. Long answer A class is one possible way to implement object oriented programming. But it's n...
Something like automatically ignoring all .pdf files for which a .tex of the same name exists? We can do something close to that. We can reject the commit if your change list contains pdf and ...
I have an ASP.NET Core 5 web application that provides functionality that involves file upload + rather large processing (memory consumption mainly). After each processing (with success or not) the...
From the docs Example to exclude everything except a specific directory foo/bar (note the /* - without the slash, the wildcard would also exclude everything within foo/bar): $ cat .gitignore...
Why do we have the "Participate Everywhere" ability when we haven't yet done anything? Bootstrapping. Our communities are still small, so after we rolled out the abilities system we decided to p...
Yes, it is safe unless the variable is volatile. The term used in the C99 standard for the value of an "uninitialized" variable is indeterminate. From C99 standard: Section 6.2.4 Storage duratio...
The problem is that you are using row twice with different types. for row in self.diagram: # row is str here for row in self.seed_diagram: # row is list[str] here Renaming one or the other m...
