Also, from the documentation: Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a … Read more
There are several ways: Write-Host: Write directly to the console, not included in function/cmdlet output. Allows foreground and background colour to be set. Write-Debug: Write directly to the console, if $DebugPreference set to Continue or Stop. Write-Verbose: Write directly to the console, if $VerbosePreference set to Continue or Stop. The latter is intended for extra optional information, Write-Debug for debugging (so … Read more
You’ve added an extra level of abstraction by calling the method with reflection. The reflection layer wraps any exception in an InvocationTargetException, which lets you tell the difference between an exception actually caused by a failure in the reflection call (maybe your argument list wasn’t valid, for example) and a failure within the method called. Just unwrap the … Read more
It is a RAM related issue. The documentation is self explanatory: You are trying to allocate >3GB of RAM to the VM. This requires: (a) a 64 bit host system; and (b) true hardware pass-through ie VT-x. Fast solution Allocate less than 3GB for the virtual machine. Complete solution Make sure your system is 64 … Read more
Javascript has a reverse() method that you can call in an array Not sure if that’s what you mean by ‘libraries you can’t use’, I’m guessing something to do with practice. If that’s the case, you can implement your own version of .reverse() Do note that the built-in .reverse() method operates on the original array, thus you don’t need to … Read more
Use this: Basically, the slice() operation clones the array and returns a reference to a new array. Also note that: For references, strings and numbers (and not the actual object), slice() copies object references into the new array. Both the original and new array refer to the same object. If a referenced object changes, the changes are visible to both … Read more
Here’s a couple of suggestions: Use date_range for the index: Note: we could create an empty DataFrame (with NaNs) simply by writing: To do these type of calculations for the data, use a numpy array: Hence we can create the DataFrame:
ou should ask whoever maintains the repo at git@mycogit/cit_pplus.git. Your commits were rejected by the pre-receive hook of that repo (that’s a user-configurable script that is intended to analyze incoming commits and decide if they are good enough to be accepted into the repo). It is also a good idea to ask that person to update the hook, so … Read more
If you try this: Output is: So ‘name’ is actually a pointer to the array of characters in memory. If you try reading the first four bytes at 0xbff5391b, you will see ‘s’, ‘i’, ‘v’ and ‘a’ To print a character you need to pass the value of the character to printf. The value can … Read more
