was that a middle way between warn and ban?
yes

max between 1 and a number that I REALLY expect to be at least 1, after subtracting 0
Nikolas
makes sense

Good morning to all

Also if it is going to do some sort of implicit conversion won't it do it anyways, looking at the type that the function takes?
Ludovic 'Archivist'
Yeah but the same can happen with subtraction?
Not sure, I don't know the types involved and it may rely on a specifically designed type with that property

Group, I’m developing a software. I enter here in order to debate and try to elevate the quality of my algorithms
Leinier
And, by the way, share with you all some of my thoughts
Leinier
I’m in the process of creating a module that process files and extract informations that will be stored in a database. I want that process be fast, that’s why I created an algorithm to be able to process that files in parallel
Leinier
It’s my first time making that. I want to share with you my algorithm and debate about it
Mihail
Unless you use some weird keyboard layout where 0 is next to 1

The same way as double/int => int
that's not how it works...
double divided by int results in double

just use the ROUND opcode

here is the major part of the algorithm:
while (filesQueue.empty() == false) {
cleanProcessedFiles();
if (filesQueue.size() < _configuration.filesProcessingThreads()) {
for (unsigned short i = 0; i < _configuration.filesProcessingThreads(); i++) {
if (filesQueue.empty() == true) { break; }
createNewFileProcessing();
}
sleepFor(milliseconds(500));
}
}
Leinier
that algorithm do the magic. i define a configuration variable named 'filesProcessingThreads' and I assign a value, i.e. 4. the algorithm then maintain 4 slots of file processing, and when one finish, then it's deleted, one slot is avaible and then one file processing is created
Leinier
what do you think about that? do you see something bad?
Leinier
that algorithm runs in a thread in order to not to block the main process, so there is other code for termination signal monitorization and cleanup code that I omit
Mihail
here is the major part of the algorithm:
while (filesQueue.empty() == false) {
cleanProcessedFiles();
if (filesQueue.size() < _configuration.filesProcessingThreads()) {
for (unsigned short i = 0; i < _configuration.filesProcessingThreads(); i++) {
if (filesQueue.empty() == true) { break; }
createNewFileProcessing();
}
sleepFor(milliseconds(500));
}
}
First of all anything starting with _ is bad and technically undefined behavior

Hey guys one quick question.
I have a variable of datatype std::vector<std::string> say vecstr
Now I want to initialize values of vecstr how can I achieve that?
Leinier

there is some site that talk about that? that works for me very good until now, but I'm open to read about that and learn
Mihail

It will probably work, but it's not guaranteed to work
Mihail
And that's the important part

std::vector<std::string> vecstr {"str1", "str2"} etc.

K thanks

i am new here 😅😅

It was nothing new (foolish me) , still thanks
Leinier

i think it works well, just like
#ifdef linux
#endif // linux

while (filesQueue.empty() == false) {
cleanProcessedFiles();
if (filesQueue.size() < _configuration.filesProcessingThreads()) {
for (unsigned short i = 0; i < _configuration.filesProcessingThreads(); i++) {
if (filesQueue.empty() == true) { break; }
createNewFileProcessing();
}
sleepFor(milliseconds(500));
}
}
Also is _configuration::filesProcessingThreads() constexpr? Because if it isn't then those calls seem a bit redundant

So.........can this group be used by beginners ??
I dont wanna get a ban......thats why...?

Yes, but not googling a question first might get you a warning
Leinier

no, that is a function that returns the value of a variable if it's assigned different from 0, or the number of detected cpu in the system if it's 0
Mihail
no, that is a function that returns the value of a variable if it's assigned different from 0, or the number of detected cpu in the system if it's 0
Then storing the result of a call to that function might be better
Mihail
In the while loop
Leinier
???
i explain: the c headers used in gnu version makes a definition of several variables that start with _
i think if that works perfectly then all the variables starting with _ but with different names should works perfectly as well
Mihail

Yes except that you don't know which variables start with _
Leinier
i don't think that using _ before the name of the variable has negatives results. and I do something extra: define a namespace for my software, so every variable is within the custom namespace, making all variables completely unique
Mihail
Mihail
Actually no, because it'd still inherit everything from :: (the global namespace)
Mihail
Wait no
Mihail
Either ways technically everything starting with _ is undefined behavior
Mihail
Also what were you referring to with that ifdef example?
Leinier
#ifdef linux
#endif // linux
Leinier
i'm trying to write _ _ linux _ _
Leinier
but when I put that together then telegram erased it
Mihail
Yeah italic formatting
Leinier
uhhmmm
Mihail
But how's that relevant?

createNewFileProcessing();
}
sleepFor(milliseconds(500));

}
Also what happens if filesQueue.size() is >= to _configuration.filesProcessingThreads()

What is faster in between these in case of arrays ?
1.merge sort 2.selection sort 3.insertion sort

1.merge sort 2.selection sort 3.insertion sort
mergesort has an algorithmic complexity of O(nlogn)
The other two are O(n^2)

BTW you could have find with a google search...
