output

is their an option to save the outpout of a curl request in a php variable? Because if i only save the $result i get a 1 or nothing <?php $url='http://icanhazip.com'; $proxy=file ('proxy.txt'); $useragent='Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)'; for($x=0;$x<count($proxy);$x++) { $ch = curl_init(); //you might need to set some cookie details up (depending on the site) curl_setopt($ch, CURLOPT_TIMEOUT, 1); curl_setopt($ch, CURLOPT_URL,$url); //set the url we want to use curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0); curl_setopt($ch, CURLOPT_PROXY, $proxy[$x]); curl_setopt($ch,

Say I have a function foo that can return three values given an input: function [a,b,c] = foo(input) The calculations of variables b and c take a long time, so sometimes I may wish to ignore their calculation within foo . If I want to ignore both calculations, I simply call the function like this: output1 = foo(input); and then include nargout within foo : if nargout == 1 % Code to calculate "a" only else % Code to calculate other variables The problem occurs if I want to calculate the last output, but not the second. In that case my function call would be: [output1,~,output3] = foo(input);

For python / pandas I find that df.to_csv(fname) works at a speed of ~1 mln rows per min. I can sometimes improve performance by a factor of 7 like this: def df2csv(df,fname,myformats=[],sep=','): """ # function is faster than to_csv # 7 times faster for numbers if formats are specified, # 2 times faster for strings. # Note - be careful. It doesn't add quotes and doesn't check # for quotes or separators inside elements # We've seen output time going down from 45 min to 6 min # on a simple numeric 4-col dataframe with 45 million rows. """ if len(df.columns) <= 0: return Nd = len(df.columns) Nd

Here's the problem. This code: String a = "0000"; System.out.println(a); char[] b = a.toCharArray(); System.out.println(b); returns 0000 0000 But this code: String a = "0000"; System.out.println("String a: " + a); char[] b = a.toCharArray(); System.out.println("char[] b: " + b); returns String a: 0000 char[] b: [C@56e5b723 What in the world is going on? Seems there should be a simple enough solution, but I can't seem to figure it out. When you say System.out.println(b); It results in a call to print(char[] s) then println() The JavaDoc for print(char[] s) says: Print an array of characters.

Here I have a very simple program: printf("Enter your number in the box below\n"); scanf("%d",&number); Now, I would like the output to look like this: Enter your number in the box below +-----------------+ | |*| | +-----------------+ Where, |*| is the blinking cursor where the user types their value. Since C is a linear code, it won't print the box art, then ask for the output, it will print the top row and the left column, then after the input print the bottom row and right column. So, my question is, could I possibly print the box first, then have a function take the cursor back into the

I want ctest to show me the failed tests output by default. That is, I want to run: $ make all test and see any output of failed tests without having to cat Testing/Temporary/LastTest.log . It appears that there are two ways of doing this: (1) Setting the CTEST_OUTPUT_ON_FAILURE environmental variable: $ CTEST_OUTPUT_ON_FAILURE=1 make all test $ # or CTEST_OUTPUT_ON_FAILURE=1 ctest (2) Specifying the --output-on-failure flag to the ctest invocation: $ ctest --output-on-failure Is there a way to write a CMakeLists.txt file such that ctests dumps failed tests output by default on a normal "make
