Chrome Web Inspector: Find And Replace

Answer : Nothing built in natively. There is a Search and Replace plugin that might help if you want to change text in the input fields . Alternatively if you want to search and replace in the HTML you could Right Click → Edit as HTML the <body> in the DevTools Elements Panel select all the text with Ctrl + a , paste into your favourite editor, make the change there and paste it back. ***Taken from this page at labnol.org**** While you are on the web page, press Ctrl+Shift+J on Windows or Cmd+Opt+J on Mac to open the Console window inside Chrome Developer tools. Now enter the following commands to replace all occurrences of the word ABC with XYZ. document.body.innerHTML = document.body.innerHTML.replace(/ABC/g, "XYZ") document.head.innerHTML = document.head.innerHTML.replace(/ABC/g, "XYZ")

Ansible Command Module Says That '|' Is Illegal Character

Answer : From the doc: command - Executes a command on a remote node The command module takes the command name followed by a list of space-delimited arguments. The given command will be executed on all selected nodes. It will not be processed through the shell, so variables like $HOME and operations like "<", ">", "|", and "&" will not work (use the shell module if you need these features). shell - Executes a commands in nodes The shell module takes the command name followed by a list of space-delimited arguments. It is almost exactly like the command module but runs the command through a shell (/bin/sh) on the remote node. Therefore you have to use shell: dpkg -l | grep python-apt . read about the command module in the Ansible documentation: It will not be processed through the shell, so .. operations like "<", ">", "|", and "&" will not work As it recommends, use t...

AngularJS - Convert Dates In Controller

Answer : item.date = $filter('date')(item.date, "dd/MM/yyyy"); // for conversion to string http://docs.angularjs.org/api/ng.filter:date But if you are using HTML5 type="date" then the ISO format yyyy-MM-dd MUST be used. item.dateAsString = $filter('date')(item.date, "yyyy-MM-dd"); // for type="date" binding <input type="date" ng-model="item.dateAsString" value="{{ item.dateAsString }}" pattern="dd/MM/YYYY"/> http://www.w3.org/TR/html-markup/input.date.html NOTE: use of pattern="" with type="date" looks non-standard, but it appears to work in the expected way in Chrome 31. create a filter.js and you can make this as reusable angular.module('yourmodule').filter('date', function($filter) { return function(input) { if(input == null){ return ""; } var _date = $filter('date')(new Date(input), ...

C++ Code File Extension? .cc Vs .cpp

Answer : At the end of the day it doesn't matter because C++ compilers can deal with the files in either format. If it's a real issue within your team, flip a coin and move on to the actual work. GNU GCC recognises all of the following as C++ files, and will use C++ compilation regardless of whether you invoke it through gcc or g++: .C , .cc , .cpp , .CPP , .c++ , .cp , or .cxx . Note the .C - case matters in GCC, .c is a C file whereas .C is a C++ file (if you let the compiler decide what it is compiling that is). GCC also supports other suffixes to indicate special handling, for example a .ii file will be compiled as C++, but not pre-processed (intended for separately pre-processed code). All the recognised suffixes are detailed at gcc.gnu.org Great advice on which to use for the makefile and other tools, considering non-compiler tools while deciding on which extension to use is a great approach to help find an answer that works for you. I just wanted to add ...

Casting Datareader Value To A To A Nullable Variable

Answer : Use the "IsDbNull" method on the data reader... for example: bool? result = dataReader.IsDbNull(dataReader["Bool_Flag"]) ? null : (bool)dataReader["Bool_Flag"] Edit You'd need to do something akin to: bool? nullBoolean = null; you'd have bool? result = dataReader.IsDbNull(dataReader["Bool_Flag"]) ? nullBoolean : (bool)dataReader["Bool_Flag"] Consider doing it in a function. Here's something I used in the past (you can make this an extension method in .net 4): public static T GetValueOrDefault<T>(SqlDataReader dataReader, System.Enum columnIndex) { int index = Convert.ToInt32(columnIndex); return !dataReader.IsDBNull(index) ? (T)dataReader.GetValue(index) : default(T); } Edit As an extension (not tested, but you get the idea), and using column names instead of index: public static T GetValueOrDefault<T>(this SqlDataReader dataReader, string columnName) { return !dataR...

Building Dockerfile Fails When Touching A File After A Mkdir

Image
Answer : Looking at https://registry.hub.docker.com/u/library/jenkins/, it seems that /var/jenkins_home is a volume. You can only create files there while the container is running, presumably with a volume mapping like docker run ... -v /your/jenkins/home:/var/jenkins_home ... The docker build process knows nothing about shared volumes. This is currently investigated in docker/docker/issues/3639, and summarized in this comment: Okay, I did little research and it seems that volume is non-mutable between Dockerfile instruction . Here even smaller Dockerfile for testing: FROM busybox RUN mkdir /tmp/volume RUN echo "hello" > /tmp/volume/hello VOLUME ["/tmp/volume/"] RUN [[ -f /tmp/volume/hello ]] RUN rm /tmp/volume/hello RUN [[ ! -e /tmp/volume/hello ]] On each instruction we create new volume and copy content from original volume . Update April 2019: Use DOCKER_BUILDKIT=1 The new builder does not exhibit this behavior. Example...

Chrome Push Notification - How To Open URL Adress After Click?

Answer : I am guessing you are in a Service Worker context, because that's where Push Notifications are received. So you have the self object to add a event listener to, that will react to a click on the notification. self.addEventListener('notificationclick', function(event) { let url = 'https://example.com/some-path/'; event.notification.close(); // Android needs explicit close. event.waitUntil( clients.matchAll({type: 'window'}).then( windowClients => { // Check if there is already a window/tab open with the target URL for (var i = 0; i < windowClients.length; i++) { var client = windowClients[i]; // If so, just focus it. if (client.url === url && 'focus' in client) { return client.focus(); } } // If not, then open the target URL in a new window/tab. if (clients.open...

Clear Azure Redis Cache

Answer : For Azure's Redis service, the Azure portal has a built-in console (which is in Preview): At this point, it's as simple as executing a flushall command: If you're running Redis in, say, a VM, you'll need to use a tool to connect remotely to the cache and run the flushall command.

Android Studio - No Target Device Found

Answer : Go to Run in the toolbar. Select Edit Configurations.. On the left panel, you'll see your application (app). On the right under Deployment Target Options choose Target as Open Select Deployment Target Dialog option. And the other option as it is. I ended up downloading the official Samsung ADB from here: http://developer.samsung.com/technical-doc/view.do?v=T000000117 And it worked great after that. Thanks everyone! On the phone Have you enabled Developer Mode? Have you enabled USB debugging within the Developer Tools menu in settings (this menu doesn't appear unless you've enabled Developer Mode) Do you have a good and securely connected USB cable? In Android Studio In Edit Run/Debug Configurations, do you have "Target: USB Device"? It seems to help me to press the "Attach debugger to Android process" icon (a tall rectangle with a green beetle) and cancelling before pressing the "Debug app" icon In Windows ...
