However, I get an error: ValueError: operands could not be broadcast together with shapes (10) (10,3) where 10 is the length of my existing array, and (3,) is the shape of the field I want to append. For example: import numpy as np from numpy.lib.recfunctions import append_fields my_structured_array = np.array( zip([0

Please focus on the fact that it doesn't work and not why you would be doing this in the first place, it is purely a theoretical question about a technical exercise. This is a rather weird one. I'm attempting to construct a variable variable using a string named $GLOBALS . From the global scope Let's see what we get when var_dump() ing this in the global scope. $g = sprintf('%s%s%s%s%s%s%s', chr(71), chr(76), chr(79), chr(66), chr(65), chr(76), chr(83));

To clarify, it'd be great for the time zone abbreviation to be parsed into useful information by as.POSIXct() , but more core to be question is how to get the function to at least ignore the time zone. Here is my best workaround, but is there a particular format code to pass to as.POSIXct() that will work for all time zones? times <- c("Fri Jul 03 00:15:00 EDT 2015", "Fri Jul 03 00:15:00 GMT 2015") as.POSIXct(times, format="%a %b %d %H:%M:%S %Z %Y") #

However i feel it is hard to find proper documentation for the different options in regards of compiler optimization. I have read a lot of questions and articles about other peoples microbenchmarks of the language, however it would be nice to have some firm documentation on the subject. In the latest beta, the ones to use seems to be: -Onone No optimizations -O Safe optimizations? -Ounchecked (Replaced -Ofast) Unsafe optimizations, (No checks for integer overflow,

Right now when playing back a #360 video on my iPhone I'm able to move around in 360 degrees but the splitview is not an option. If I do the same thing on an Android Device I have an option to enter "splitview" for Google Cardboard . Is it possible to trigger this splitview mode also from the iPhone or if a #360 video is embedded into a website with a parameter or via the API? 回答1: According to the

I defined a blank line in my XHTML file as 2 consecutive HTML BR tags. Now there is no native support for a blank line in the XSL-FO format. I want to work around this limitation by adding a height to the fo:block that the stylesheet inserts for a BR tag. However I'm new to the XSLT language and I'm having some problems doing this. I can figure out how to insert this height for every BR tag I encounter, but I only want the blank line to be inserted when there
