[ad_1] Your cwd[1] != 0 or cwd[1] != ‘\0′ is an okay way to do it. There’s no need to cast that to an int. You could also use strcmp(cwd, “https://stackoverflow.com/”), which makes it slightly more clear what you are doing. This will be zero at the root directory on a UNIX or Linux system. … Read more
[ad_1] <(command) is a bashism called Process substitution You have to run your script with bash, eg do bash script.bash Or if you want to use sh, you could write the results to a file, like this : grep eth0 /proc/net/dev > file1 sleep 1 ; grep eth0 /proc/net/dev > file2 diff file1 file2 7 … Read more
[ad_1] Omg! Format your code! Icons by Bootstrap or Semantic are fonts, not images. So if you want to place a image as an icon on a button you should do something like that: button { background: url(youricon) no-repeat ….; padding-left: 25px; } It just places an image on the leftside of your button and … Read more
[ad_1] Your code is equivalent to: double x1 = 0.9; float xf = (float)x1; // discard some precision double x2 = (double)xf; if (x2 >= x1) { // … } The problem is that, after you discarded some precision from x1 by converting it to float, it can never be recovered; casting it back to … Read more
[ad_1] If two strings are equal to each other. When comparing two strings, you have to pass in the strings. public static boolean isEquals(String a, String b) { if (a.length() != b.length()) return false; return isEquals(a, b, 0); } private static boolean isEquals(String a, String b, int index) { if (index >= a.length()) return true; … Read more
[ad_1] import subprocess subprocess.Popen([‘xterm’, ‘-hold’, ‘-e’, ‘nmap -sV 74.125.130.100’]) this is more easy to execute [ad_2] solved Sub-process in Python execute two task? [closed]
[ad_1] This is the working eg of first 3 and next 3 check boxes, but as suggestion please don’t have these many check boxes, the user experience is very bad in this case. $(document).ready(function() { var $cbs = $(‘input:checkbox’), $links = $(“a”); $links.click(function() { var start = $links.index(this) * 3, end = start + 3; … Read more
[ad_1] Just use standard shell redirection: python your_script.py > output_file.ext If you want to write to a file directly from the script without redirecting: with open(“output.ext”, “w”) as stream: print >>stream, “text” 3 [ad_2] solved Redirect the output of python script into a text file [duplicate]
[ad_1] The correct syntax is if condition: # stuff elif other: # stuff elif some_other: # stuff else: # stuff Note that else does not get any explicit condition, it is the catch-all if none of the above conditions were True. 3 [ad_2] solved Proper if..else syntax in Python
[ad_1] You can use substr() as an lvalue and start replacing the string from right side of it, my $string = ‘GATGCAGTTAGGCGTAGCAGAGTGAGACGACGACGATATTAGGACCCGGTAAGGCACAATATAGC’; my %coord_colors = ( 10 => “red”, 48 => “orange”, 60 => “purple”, ); substr($string,$_,0) = $coord_colors{$_} for sort { $b <=> $a } keys %coord_colors; print $string; output GATGCAGTTAredGGCGTAGCAGAGTGAGACGACGACGATATTAGGACCCGorangeGTAAGGCACAATpurpleATAGC using regex, $string … Read more
[ad_1] With the commented-out code uncommented, you’re trying to declare a constructor directly within a method. You can’t do that in Java. // You can’t do this buttonPlay.addListener(new ClickListener(){ // 1 public void clicked(InputEvent event, float x, float y) { // 2 public GameScreen(Create create) { // 3 this.create = create; // 3 } // … Read more
[ad_1] The compilation error exactly tells you where to look. MyFirstApp.java:7 implies there is something wrong at line 7. If you go through your code at line 7 there is an extra closing bracket. Remove this bracket and it would start compiling perfectly. [ad_2] solved MyFirstApp.java:7: error: class, interface, or enum expected [closed]
[ad_1] I’m not familiar with Notepad code, but this looks like almost any batch file. Assuming that assumption is accurate, the first line verifies the date. If it does not equal 2015/8/27 execution will jump to the “exit” label, after which the process will terminate. If, on the other hand, the date matches then it … Read more
[ad_1] I don’t know Python but this is Java so hopefully you can translate it. I put the board into a two-dimensional array of int in the form board[1][2] = 16 where the class on that tile would be tile tile-16 tile-position-1-2 tile-new. I know that’s not what you asked for but you didn’t give … Read more
[ad_1] Using these functions makes your site less vulnerable to SQL injection attacks, where an attacker puts SQL syntax into a form field to compromise your site. mysqli_real_escape_string() “escapes” special characters so that MySQL interprets them as literal string characters rather than operators in the query. These functions only affect characters that are important to … Read more
