Answer : The main reason to run the algorithm for a certain amount of rounds is simply to slow it down to make brute forcing attacks uninteresting. For that 5000 iterations are enough even for modern hardware. You could as well use 100000 but then your server admin would probably want to have a word with you :-) rounds=5000 is the default for SHA-512. The minimum is 1000 and the maximum very high. Use OpenSSL for salt generation, it's even more random. And maybe 20000 rounds to future proof your code a bit. function cryptPassword($password, $salt = "", $rounds = 20000) { if ($salt == "") { // Generate random salt $salt = substr(bin2hex(openssl_random_pseudo_bytes(16)),0,16); } // $6$ specifies SHA512 $hash = crypt($password, sprintf('$6$rounds=%d$%s$', $rounds, $salt)); return $hash; }

Answer : A Kotlin data class must have a primary constructor that defines at least one member. Other than that, you can add secondary constructors as explained in Classes and Inheritance - Secondary Constructors. For your class, and example secondary constructor: data class User(val name: String, val age: Int) { constructor(name: String): this(name, -1) { ... } } Notice that the secondary constructor must delegate to the primary constructor in its definition. Although many things common to secondary constructors can be solved by having default values for the parameters. In the case above, you could simplify to: data class User(val name: String, val age: Int = -1) If calling these from Java, you should read the Java interop - Java calling Kotlin documentation on how to generate overloads, and maybe sometimes the NoArg Compiler Plugin for other special cases. Yes, but each variable should be initialized, so you may set default arguments in your data class constructo

Example 1: jquery display none The correct way to do this is to use show and hide : $ ( '#id' ) . hide ( ) ; $ ( '#id' ) . show ( ) ; An alternate way is to use the jQuery css method : $ ( "#id" ) . css ( "display" , "none" ) ; $ ( "#id" ) . css ( "display" , "block" ) ; Example 2: display none in jquery // The correct way to do this is to use show and hide : <div id= "check" > <h3> Hello we check hide / show by jquery </h3> </div> //Syntex $ ( '#yourid' ) . hide ( ) ; $ ( '#yourid' ) . show ( ) ; // Example $ ( '#check' ) . hide ( ) ; $ ( '#check' ) . show ( ) ; // Alternate way is to use the jQuery by css method : //Syntex $ ( "#yourid" ) . css ( "display" , "none" ) ; $ ( "#yourid" ) . css ( "display" , "block" ) ; //Example $ ( "#clear" ) . css ( "display&quo

Answer : No, unfortunately Telegram Bot API doesn't return phone number. You should either use Telegram API methods instead or ask it explicitly from the user. You cannot get "friends" of a user as well. You will definitely retrieve the following information: userid first_name content (whatever it is: text, photo, etc.) date (unixtime) chat_id If user configured it, you will also get last_name and username . It's possible with bots 2.0 check out bot api docs. https://core.telegram.org/bots/2-0-intro#locations-and-numbers https://core.telegram.org/bots/api#keyboardbutton

Answer : Additionally to overflow:hidden, use white-space:nowrap; Just use: overflow: hidden; white-space: nowrap; In your item's divs Use the css property overflow . For example: .item{ width : 100px; overflow:hidden; } The overflow property can have one of many values like ( hidden , scroll , visible ) .. you can als control the overflow in one direction only using overflow-x or overflow-y . I hope this helps.

Defined in header <cstring> char *strcat( char *dest, const char *src ); Appends a copy of the character string pointed to by src to the end of the character string pointed to by dest . The character src[0] replaces the null terminator at the end of dest . The resulting byte string is null-terminated. The behavior is undefined if the destination array is not large enough for the contents of both src and dest and the terminating null character. The behavior is undefined if the strings overlap. Parameters dest - pointer to the null-terminated byte string to append to src - pointer to the null-terminated byte string to copy from Return value dest . Example #include <cstring> #include <cstdio> int main() { char str[50] = "Hello "; char str2[50] = "World!"; std::strcat(str, str2); std::strcat(str, " Goodbye World!"); std::puts(str); } Output: Hello World! Goodbye World! See

Answer : Good downscaling algorithm (not nearest neighbor like) consists of just 2 steps (plus calculation of the exact Rect for input/output images crop): downscale using BitmapFactory.Options::inSampleSize->BitmapFactory.decodeResource() as close as possible to the resolution that you need but not less than it get to the exact resolution by downscaling a little bit using Canvas::drawBitmap() Here is detailed explanation how SonyMobile resolved this task: http://developer.sonymobile.com/2011/06/27/how-to-scale-images-for-your-android-application/ Here is the source code of SonyMobile scale utils: http://developer.sonymobile.com/downloads/code-example-module/image-scaling-code-example-for-android/ Try below mentioned code for resizing bitmap. public Bitmap get_Resized_Bitmap(Bitmap bmp, int newHeight, int newWidth) { int width = bmp.getWidth(); int height = bmp.getHeight(); float scaleWidth = ((float) newWidth) / width; float scaleH
