Example: bash command to clear screen Ctrl+L shortcut key

Answer : In newer versions of bash (at least v2), builtins may be loaded (via enable -f filename commandname ) at runtime. A number of such loadable builtins is also distributed with the bash sources, and sleep is among them. Availability may differ from OS to OS (and even machine to machine), of course. For example, on openSUSE, these builtins are distributed via the package bash-loadables . Edit: fix package name, add minimum bash version. Creating a lot of subprocesses is a bad thing in an inner loop. Creating one sleep process per second is OK. There's nothing wrong with while ! test_condition; do sleep 1 done If you really want to avoid the external process, you don't need to keep the fifo open. my_tmpdir=$(mktemp -d) trap 'rm -rf "$my_tmpdir"' 0 mkfifo "$my_tmpdir/f" while ! test_condition; do read -t 1 <>"$my_tmpdir/f" done I recently had a need to do this. I came up with the following function that will al...

Answer : The fact is that browsers can't talk to (cryptographic) smart cards for other purposes than establishing SSL. You shall need additional code, executed by the browser, to access smart cards. There are tens of custom and proprietary plugins (using all three options you mentioned) for various purposes (signing being the most popular, I guess) built because there is no standard or universally accepted way, at least in Europe and I 'm sure elsewhere as well. Creating, distributing and maintaining your own shall be a blast, because browsers release every month or so and every new release changes sanboxing ir UI tricks, so you may need to adjust your code quite often. And you probably would want to have GUI capabilities, at least for asking the permission of the user to access a card or some functionality on it. For creating a multiple-platform, multiple browser plugin, something like firebreath could be used. Personally, I don't believe that exposing PC/S...

Example: is c and c++ platform independent In C , C ++ the compiled code ( compiler given code ) is machine language code which is understandable only by the cureent operating system . Hence this compiled code can not be executed in another platform . Due to this reason these languages are considered as platform dependent programming languages .

Answer : Angular 2 Style Guide According to the official Angular 2 style guide, STYLE 05-12 says Do use @Input and @Output instead of the inputs and outputs properties of the @Directive and @Component decorators The benefit is that (from the guide): It is easier and more readable to identify which properties in a class are inputs or outputs. If you ever need to rename the property or event name associated with @Input or @Output , you can modify it a single place. The metadata declaration attached to the directive is shorter and thus more readable. Placing the decorator on the same line makes for shorter code and still easily identifies the property as an input or output. I've personally used this style and really appreciate it helping keep the code DRY. One of the cool thing that I know you can do with decorators but I'm not if it's possible with the other way, is aliasing the variable: export class MyComponent { @Output('select') $onSelec...

Answer : You can use the Snippet Generator for General SCM step. This displays the familiar Subversion configuration options, and takes credentials as parameter as usual. The Snippet Generator will produce a tad ugly representation of your parameter selections and looks something like this: checkout([$class: 'SubversionSCM', additionalCredentials: [], excludedCommitMessages: '', excludedRegions: '', excludedRevprop: '', excludedUsers: '', filterChangelog: false, ignoreDirPropChanges: false, includedRegions: '', locations: [[credentialsId: '34761a89-1402-47d7-96e2-aec22ffdc50b', depthOption: 'infinity', ignoreExternalsOption: true, local: 'cable_branch', remote: "https://trac.nci.org.au/svn/cable/branches/$SVN_...

Answer : You can use the ARCamera.transform property to get the current transform of your camera. The following code is from Introducing ARKit at WWDC 2017 which you probably want to watch as an introduction. We are using the transform to place a node 10 cm in front of the camera. In Swift: var translation = matrix_identity_float4x4 translation.columns.3.z = -0.1 // Translate 10 cm in front of the camera node.simdTransform = matrix_multiply(currentFrame.camera.transform, translation) In Objective-C matrix_float4x4 translation = matrix_identity_float4x4; translation.columns[3][2] = -0.1; // Translate 10 cm in front of the camera node.simdTransform = matrix_multiply(currentFrame.camera.transform, translation)

Answer : You sound right. Why don't you test it. There is also this app that can help explain launch mode: https://play.google.com/store/apps/details?id=com.novoda.demos.activitylaunchmode Sources are at https://github.com/gnorsilva/Activities-LaunchMode-demo The ActivityC will be removed from task1 and ActivityB becomes the top Activity. Yes, you are Right... ActivityC will be removed from i.e. the onDestroy method of the ActivityC will be called. Hence when the user launches Task 1 again, the ActivityB is shown rather than ActivityC. Have created 2 Tasks (Projects) and uploaded the same @ SendSpace. Try it out... If you look at androids documentation it says " A "singleTask" activity allows other activities to be part of its task. It's always at the root of its task, but other activities (necessarily "standard" and "singleTop" activities) can be launched into that task." This means that when you click the hom...
