The process of showing an image in memory to the screen-buffer is done deep inside the Java API by a process called blitting. The details differ between the type of image you use and even between Java versions. Images in Java can be ‘accelerated’ which means they can be anything between an image compatible with … Read more

Maybe try this: for x in list_of_data: if x == ‘[]’: pass else: print(x) That should at least get rid of the empty brackets. I don’t know what to do, this doesn’t look like a normal datatype for Python… 4 solved How do I add commas to this to make it into a proper list … Read more
Replace , with = it will also work fine! Initialize variable var scores = { val1: 90, val2: 100, val3: 98, val4: 95 } function calcAverage() { var sum = size = 0; for (var key in this) { sum += this[key]; size++; } return sum / size; } console.log(calcAverage.apply(scores)); 5 solved Why print ‘NaN’ … Read more
This should do it: $(“.hot_post_thumbnail”).hover(function(){ $(this).closest(“.hot_post_title”).show(); $(this).closest(“img”).show(); }); solved Jquery show hover effect [duplicate]
The prepare statement returns an object, you can execute that object. Thus $query->execute() – the first parameter of execute can be an array. Alternatively, you can use the bindParam function first on that same $query object instead of passing an array though. Anyways, here you are: <?php if(isset($_POST[‘username’], $_POST[‘password’])){ try{ $username=”root”; $password = ”; $conn … Read more
$csv_array[1];, $csv_array[2]; and $csv_array[3]; don’t exists inside your $csv_array. As suggested, do a var_dump($csv_array) below $csv_array = explode(“,”, $csv_data[$i]); and see what is in there! 0 solved Undefined offset:1, 2 3 etc
Just for a quick testing purpose, try this below which is a bare bones method. You can then slowly build up sanitizing and troubleshoot from thereon. <?php $username = $_POST[‘username’]; $password = sha1($_POST[‘password’]); $link = mysqli_connect(‘xxx’, ‘xxx’, ‘xxx’, ‘xxx’); $query = “SELECT password, id FROM users WHERE username=”$username” AND password=’$password'”; $result = mysqli_query($link, $query); if(mysqli_num_rows($result) … Read more
I think using Regular Expression works better. private static String setSize(String htmlString) { String reg = “size=”[0-9]+””; Pattern pattern = Pattern.compile(reg); Matcher matcher = pattern.matcher(htmlString); while (matcher.find()) { String sizeString = matcher.group(); pattern = Pattern.compile(“[0-9]+”); Matcher numMatcher = pattern.matcher(sizeString); if (numMatcher.find()) { String size = numMatcher.group(); int realSize = Integer.parseInt(size); int resultSize = realSize / … Read more
A simple test for whether some integer N is a Fibonacci number is as follows: N is a Fibonacci number iff either (5 * n^2 + 4) or (5 * n^2 – 4) is a square number. See here for the ingenious proof (page 417): http://www.fq.math.ca/Scanned/10-4/advanced10-4.pdf If it turns out that N is not a … Read more

Go is lexically scoped using blocks. In this example: list := []string{“a”, “b”, “c”} for { list := repeat(list) The second list shadows the first within the for block, and doesn’t alter the outer list variable. Because the arguments to repeat are evaluated before the inner list is declared and assigned, repeat receives the value … Read more
