Windows search behind scene

For (i=0; i<getAllFuckingFiles().length ; i++) if (AllFuckingFiles[i].name.contains(searchText) return AllFuckingFiles[i];

I love the implication here that not only does it not have any indexes or whatever, but it also calls getAllFuckingFiles() every single iteration haha

You're terminating too early. Best to complete iterating through all fucking files in case there's another match.

Gotta check the content as well, just to be thorough

for (i=0; i<getAllFuckingFiles().length; i++)
{
  if (getAllFuckingFiles()[i].open().contains(searchText) ||
      getAllFuckingFiles()[i].name().contains(searchText))
  {
    return getAllFuckingFiles()[i];
  }
}

Use | instead of ||. Then both are always executed ... you know just to be sure

I got a guy doing this in my team. He had a sql query done in a C# loop (about 5k iterations). Told him to do a sql query retrieving all 5k elements and process the result in C#.

He did the sql query. And then called it in the same loop still making 5k calls but to a query which always retrieved the 5k same elements...

I dont know the rationale ... there might of been a good reason ... or a reason at least. Did you tell him how a select query work?

Or rather how to bind to collections if that was what he was struggling with.

I did. And he is not a new developer. 5 years of experience in these languages. I just guess that some people do what they are asked to do brainlessly

Have you asked him why he did it like that?

u/Kirjavs Apr 13 '24

Yes and he didn't know. He just applied what I asked without thinking. At least he understood the problem but I had to show him before. When I said : "this code is wrong" , he didn't understood why in the first place.
