CSS Image Size, How To Fill, But Not Stretch?

Answer : You can use the css property object-fit . .cover { object-fit: cover; width: 50px; height: 100px; } <img src="http://i.stack.imgur.com/2OrtT.jpg" class="cover" width="242" height="363" /> See example here There's a polyfill for IE: https://github.com/anselmh/object-fit If you want to use the image as a CSS background, there is an elegant solution. Simply use cover or contain in the background-size CSS3 property. .container { width: 150px; height: 100px; background-image: url("http://i.stack.imgur.com/2OrtT.jpg"); background-size: cover; background-repeat: no-repeat; background-position: 50% 50%; } <div class="container"></div>​ While cover will give you a scaled up image, contain will give you a scaled down image. Both will preserve the pixel aspect ratio. http://jsfiddle.net/uTHqs/ (using cover) http://jsfiddle.net/HZ2FT/ (using contain) This approach has the advantage

Can't Reset Root Password With --skip-grant-tables On Ubuntu 16

Answer : I found that the mysql.sock is deleted when the mysql service is stoped and mysqld_safe can't create it (I couldn't find the reason), so my solution was back up the sock folder and restore before start mysqld_safe Start server $ sudo service mysql start Go to sock folder $ cd /var/run Back up the sock $ sudo cp -rp ./mysqld ./mysqld.bak Stop server $ sudo service mysql stop Restore the sock $ sudo mv ./mysqld.bak ./mysqld Start mysqld_safe $ sudo mysqld_safe --skip-grant-tables --skip-networking & Init mysql shell mysql -u root Change password FLUSH PRIVILEGES; SET PASSWORD FOR root@'localhost' = PASSWORD('my_new_password'); For Ubuntu 19 with MySQL 8.0.17-0ubuntu2, what ended up working for me was a combination of many answers: In the MySQL's configuration file ( /etc/mysql/mysql.conf.d/mysqld.cnf on my machine), under [mysqld] , add: skip-grant-tables = 1 plugin-load-add = auth_socket.so Restart the

Can't Enable Windows Hello - Some Settings Are Managed By Your Organization

Answer : I found the solution. The reason is that Windows Hello is managed differently on domain joined computers, starting with the anniversary update. To get it to work you have to follow these steps: 1) Setup a Group Policy Central Store (you should already have that) 2) Get Windows 10 Anniversary Update Group Policy Templates . You can do so by copying your files from PolicyDefinitions (in windir on a Win10 Anniversary Update machine) into the PolicyDefinitions of the central store. You might copy those files first to a file share, because of permissions your regular user should not have on the central store. 3) Setup a new GPO or add to an existing the following settings to enable Windows Hello: Computer Configuration/Policies/Administrative Templates .../Windows Components/Windows Hello For Business/ Use biometrics => Enabled .../Windows Components/Windows Hello for Business/ Use a hardware security device => Enabled (if you want to use TPM instead of k

Dynamic Memory Allocation In C Geeksforgeeks Code Example

Example 1: what is dynamic memory allocation in c++ In the dynamic memory allocation the memory is allocated during run time . The space which is allocated dynamically usually placed in a program segment which is known as heap . In this , the compiler does not need to know the size in advance . In C ++ , dynamic memory allocation means performing memory allocation manually by programmer . It is allocated on the heap and the heap is the region of a computer memory which is managed by the programmer using pointers to access the memory . The programmers can dynamically allocate storage space while the program is running but they cannot create a new variable name . Example : Example 2: dynamic memory allocation in c++ # include <iostream> using namespace std ; int main ( ) { double * pvalue = NULL ; // Pointer initialized with null pvalue = new double ; // Request memory for the variable * pvalue = 29494.99 ; // Store value

Android - Implementing StartForeground For A Service?

Answer : I'd start by completely filling in the Notification . Here is a sample project demonstrating the use of startForeground() . From your main activity, start the service with the following code: Intent i = new Intent(context, MyService.class); context.startService(i); Then in your service for onCreate() you would build your notification and set it as foreground like so: Intent notificationIntent = new Intent(this, MainActivity.class); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); Notification notification = new NotificationCompat.Builder(this) .setSmallIcon(R.mipmap.app_icon) .setContentTitle("My Awesome App") .setContentText("Doing some work...") .setContentIntent(pendingIntent).build(); startForeground(1337, notification); Solution for Oreo 8.1 I've encountered some problems such as RemoteServiceException becau
