Dynamically adding Views in a RecyclerView only to current item
I'm dynamically adding Views to my items in a RecyclerView. These added Views should only be related to the item which they're added to, but I'm having a problem when I scroll. It seems the View is recycled and a new item is loaded, but those previously added views are still there, only now on the wrong item. I'm assuming that it's just because the ViewHolder is being reused, so the added items show up again with a new item, when loaded. How would one go about solving this? 10 AnswersAnswers 1 You need to track what...
How to correctly listen to navigation changes on UIWebView?
I noticed that the [UIWebViewDelegate webView:shouldStartLoadWithRequest:navigationType:] is only called with traditional <a href="..."> links and not single page web app JavaScript navigations. For example, if I go to m.facebook.com in a UIWebView and start tapping on the top nav (see screenshot below) it never triggers that delegate method. The reason I want a method to hook into is because I want to add back and forward...

Laravel 5.3 - Social login doubts

This token is supposed to send with all subsequent requests after login. 2) In case social platforms are...

Is it possible to use poison pill approach with bounded queues?
In Java Concurrency In Practice book (p.156), there's a statement regarding poison pill approach: Poison pills work reliably only with unbound queues. Does it mean that with a bounded queue I can get a deadlock, or is it about some other liveness problems? Is it connected with number of producers and customers? 3 AnswersAnswers 1 With a bounded queue, you could be prevented from adding the poison pill. One way to avoid this issue is to make the bounded queue allow one more when a poison pill is added. Answers...

MySQL server slow to respond with Wordpress
I have a web server running Windows, IIS, PHP that is hosting a fully patched WordPress site. The database sits on a separate server inside the DMZ that is running Windows and MySQL 5.7.13. When making a request to the WordPress site, it takes anywhere from 6 to 16 seconds to get back the first byte. Executing this ridiculously un-optimized query from MySQL Workbench (on the web server) takes only 0.858 seconds. SELECT * FROM wp_posts INNER JOIN wp_postmeta ON wp_postmeta.post_id = wp_posts.ID INNER JOIN wp_comments...

JUnit test with Embedded tomcat server , how to specify automatic ports for both http and https connectors?
Description I have made a JUnit test that focus on trying to test a call to a SOAP web service. I am using an embedded tomcat server for my test in order to run my test with a mock server. I am also using both http and https connectors. I need to use automatic ports for both these connectors because the test is running on a Jenkins server and i can't just use port 443 or 8443 as they are already taken. I understand that using the port 0 as standard port will result in tomcat using automatic port allocation but I can't...

OpenVPN routing outside IPV6 tunnel (windows)
I'm struggeling with a general OpenVPN configuration... I've an established OpenVPN connection with IPv6 and I want to exclude an IP for that tunnel... On IPv4 this works by adding --route IP MASK net_gateway default to the config, so for example if I want to exclude the google DNS from the tunnel --route 8.8.8.8 255.255.255.255 net_gateway default does the trick. But how to do that with IPv6? I know there is a --route-ipv6 command to route over the tunnel, but I didn't find a way to exclude an IP from the tunnel...
React stop other events on that element
I have a volume element that shows the volume bar when the user hovers over it. This all works great in desktop. However to get the same functionality on mobile, the user has clicks on the volume element which also toggles the mute click event. I am wanting to stop that mute event when the user clicks (i.e taps) on that element on mobile. I don't want to modify the Mute or VolumeBar classes to fix this because these are generic classes in my library that the developer uses. https://jsfiddle.net/jwm6k66c/2145/ Actual:...
