Short Answer Use buffers effectively! Long answer You might consider use :tabclose to close your tabs. This has the benefit of closing the tab (and keeping you away from your mouse) but also being just annoying enough to motivate a workflow change over to using buffers and splits. As for a warning about closing a … Read more
You may try to include library headers using -isystem instead of -I. This will make them “system headers” and GCC won’t report warnings for them.
You should just fix your code but just in case, import warnings warnings.filterwarnings(“ignore”, category=DeprecationWarning)
Warning: Cannot modify header information – headers already sent Happens when your script tries to send an HTTP header to the client but there already was output before, which resulted in headers to be already sent to the client. This is an E_WARNING and it will not stop the script. A typical example would be … Read more
Step 1: check the return code: if($content === FALSE) { // handle error here… } Step 2: suppress the warning by putting an error control operator (i.e. @) in front of the call to file_get_contents(): $content = @file_get_contents($site);
You can put it in “(void)var;” expression (does nothing) so that a compiler sees it is used. This is portable between compilers. E.g. void foo(int param1, int param2) { (void)param2; bar(param1); } Or, #define UNUSED(expr) do { (void)(expr); } while (0) … void foo(int param1, int param2) { UNUSED(param2); bar(param1); }
Consider this code: List<Action> actions = new List<Action>(); for (int i = 0; i < 10; i++) { actions.Add(() => Console.WriteLine(i)); } foreach (Action action in actions) { action(); } What would you expect this to print? The obvious answer is 0…9 – but actually it prints 10, ten times. It’s because there’s just one … Read more
The warning message is because your “Type” variable was made a factor and “lunch” was not a defined level. Use the stringsAsFactors = FALSE flag when making your data frame to force “Type” to be a character. > fixed <- data.frame(“Type” = character(3), “Amount” = numeric(3)) > str(fixed) ‘data.frame’: 3 obs. of 2 variables: $ … Read more
The obvious answer, of course, is not to do the unchecked cast. If it’s absolutely necessary, then at least try to limit the scope of the @SuppressWarnings annotation. According to its Javadocs, it can go on local variables; this way, it doesn’t even affect the entire method. Example: @SuppressWarnings(“unchecked”) Map<String, String> myMap = (Map<String, String>) … Read more
When an object written in C# is constructed, what happens is that the initializers run in order from the most derived class to the base class, and then constructors run in order from the base class to the most derived class (see Eric Lippert’s blog for details as to why this is). Also in .NET … Read more
