Example 1: best coding ide for python #To be honest i personally use Visual studio code, but IDEs made by Jetbrains are also really good. They are a bit pricy though. Of course you can get to community edition as well. '''Well, other good code editors are atom, sublime text and idle itself. By far atom is the best out of these However they are all text editors and not proper IDEs. Hope that helps. Example 2: ide for python #i presonally use pycharm but be open for other IDE's Example 3: best python IDE I would say VS Code is best. It is simple and has easy auto correct. But if you are less experienced, use IDLE until you become familiar with the programming language Example 4: best ide for python Pycharm - https://www.jetbrains.com/pycharm/ Visual Studio Code - https://code.visualstudio.com/ Example 5: the best ide for python I prefer Vim and Sublime text 3. Sublime text 3 is very beginner friendly. The UI is great and it has a lot of features. But it can

Answer : Open angular dom element schema https://github.com/angular/angular/blob/master/packages/compiler/src/schema/dom_element_schema_registry.ts#L78 where: (no prefix): property is a string. * : property represents an event. ! : property is a boolean. # : property is a number. % : property is an object. Then press ctrl+F and write * @HostListener (and also (customEvent)="handler()" ) can also listen to custom events Example The list of events you can listen to can be found here https://www.w3schools.com/jsref/dom_obj_event.asp and I believe this one is the same, but better organized (I'm not sure if all are valid) https://developer.mozilla.org/en-US/docs/Web/Events Sorry, I think you ask about a list of properties. You can use e.g. @HostListener("focus", ["$event.target"]) onFocus(target) { console.log(target.value) } @HostListener("blur", ["$event.target"]) onBlur(target) { consol

Example 1: bootstrap Margin and padding Use the margin and padding spacing utilities to control how elements and components are spaced and sized. Bootstrap 4 includes a five-level scale for spacing utilities , based on a 1 rem value default $spacer variable. Choose values for all viewports ( e.g. , .mr-3 for margin-right : 1 rem ) , or pick responsive variants to target specific viewports ( e.g. , .mr-md-3 for margin-right : 1 rem starting at the md breakpoint ) . <div class= "my-0 bg-warning" >Margin Y 0 </div> <div class= "my-1 bg-warning" >Margin Y 1 </div> <div class= "my-2 bg-warning" >Margin Y 2 </div> <div class= "my-3 bg-warning" >Margin Y 3 </div> <div class= "my-4 bg-warning" >Margin Y 4 </div> <div class= "my-5 bg-warning" >Margin Y 5 </div> <div class= "my-auto bg-warning" >Margin Y Auto</div>

Answer : This was covered by Aussie Bloke's blog when Lion arrived. Here are the steps to get both the file where the signature is stored as well as the associated keychain entry to a second Mac. On the source Mac: Open the ~/Library/Containers/com.apple.Preview/Data/Library/Preferences folder. In Finder , click the Go menu and hold option to show the Library folder. Alternatively, press ⇧⌘G whilst Finder is active and enter the path above to directly navigate. On OS X Mavericks 10.9 and earlier , copy the com.apple.Preview.signatures.plist file. On OS X Yosemite 10.10 and later , copy the com.apple.PreviewLegacySignaturesConversion.plist file. Launch Keychain Access Ensure the login keychain is selected and choose the Passwords category. On OS X Mavericks 10.9 and earlier , right-click the Preview Signature Privacy password and select Copy Password to Clipboard . This is the password used to encrypt the signature images.

Answer : On a supported Mac, run: brew install --cask docker Then launch the Docker app. Click next. It will ask for privileged access. Confirm. A whale icon should appear in the top bar. Click it and wait for "Docker is running" to appear. You should be able to run docker commands now: docker ps Because docker is a system-level package, you cannot install it using brew install , and must use --cask instead. Note: This solution only works for Macs whose CPUs support virtualization, which may not include old Macs. On macOS the docker binary is only a client and you cannot use it to run the docker daemon, because Docker daemon uses Linux-specific kernel features, therefore you can’t run Docker natively in OS X. So you have to install docker-machine in order to create VM and attach to it. Install docker-machine on macOS If you don't have docker-machine command yet, install it by using one of the following methods: Using Brew command: brew install dock

Answer : Increase yarn.nodemanager.resource.memory-mb in yarn-site.xml With 12g per node you can only launch driver(3g) and 2 executors(11g). Node1 - driver 3g (+7% overhead) Node2 - executor1 11g (+7% overhead) Node3 - executor2 11g (+7% overhead) now you are requesting for executor3 of 11g and no node has 11g memory available. for 7% overhead refer spark.yarn.executor.memoryOverhead and spark.yarn.driver.memoryOverhead in https://spark.apache.org/docs/1.2.0/running-on-yarn.html Note that yarn.nodemanager.resource.memory-mb is total memory that a single NodeManager can allocate across all containers on one node. In your case, since yarn.nodemanager.resource.memory-mb = 12G , if you add up the memory allocated to all YARN containers on any single node, it cannot exceed 12G. You have requested 11G ( -executor-memory 11G ) for each Spark Executor container. Though 11G is less than 12G, this still won't work. Why ? Because you have to account for spark.yar

Answer : Most probably you want to use a method <span>{{ fullName('Hi') }}</span> methods: { fullName(salut) { return `${salut} ${this.firstName} ${this.lastName}` } } Longer explanation Technically you can use a computed property with a parameter like this: computed: { fullName() { return salut => `${salut} ${this.firstName} ${this.lastName}` } } (Thanks Unirgy for the base code for this.) The difference between a computed property and a method is that computed properties are cached and change only when their dependencies change. A method will evaluate every time it's called . If you need parameters, there are usually no benefits of using a computed property function over a method in such a case. Though it allows you to have a parametrized getter function bound to the Vue instance, you lose caching so not really any gain there, in fact, you may break reactivity (AFAIU). You can read more about this in Vue documentation htt

Example: c++ create window HWND hwnd = CreateWindowEx ( 0 , // Optional window styles. CLASS_NAME , // Window class L "Learn to Program Windows" , // Window text WS_OVERLAPPEDWINDOW , // Window style // Size and position CW_USEDEFAULT , CW_USEDEFAULT , CW_USEDEFAULT , CW_USEDEFAULT , NULL , // Parent window NULL , // Menu hInstance , // Instance handle NULL // Additional application data ) ; if ( hwnd == NULL ) { return 0 ; }

Answer : // Try to convert the string to a float $floatVal = floatval($num); // If the parsing succeeded and the value is not equivalent to an int if($floatVal && intval($floatVal) != $floatVal) { // $num is a float } This will omit integer values represented as strings: if(is_numeric($num) && strpos($num, ".") !== false) { $this->print_half_star(); } You can try this: function isfloat($num) { return is_float($num) || is_numeric($num) && ((float) $num != (int) $num); } var_dump(isfloat(10)); // bool(false) var_dump(isfloat(10.5)); // bool(true) var_dump(isfloat("10")); // bool(false) var_dump(isfloat("10.5")); // bool(true)

Answer : For some reason that i do not understand , this combination of build versions made the issue : grade version = 4.10.1 classpath 'com.android.tools.build:gradle:3.4.0-alpha01' when i switched to these build versions : grade version = 4.6 classpath 'com.android.tools.build:gradle:3.2.1' The issue was solved !

Answer : Yes. There is just one missable trophy if you are morally opposed to using the trophy shop. The trophy is Transcendent Being and it is awarded for attaining all 26 endings. The only missable ending is ending Y. This is due to the fact that ending Y is tied to failing a side-quest. The side quest is Emil's Determination To get the ending, you need to lose the boss fight in the desert at a specific point. Near the end of the fight, one of the giant Emil heads starts a countdown timer before it explodes (and subsequently destroys the Earth), you need to simply let the timer run out. This will lead to ending Y. If you kill the Emil head (which finishes the side quest) before getting this ending, ending Y is not possible to get. Since side quests can not be repeated on a save file, if you complete this quest without getting ending Y, you will either have to redo everything and try again or cave in and use the trophy shop. However, I wouldn't recomm

Answer : Apply the following steps when the Windows partitioning window apeares: Create a partition on the blank hard. Select the partition drive as the partition to install the Windows. Click "Next". The 100MB partition will be created. Delete the partition which you created in step 1. Extend the 100MB partition to the desired size. Select the partition which you extended in step 5 and select 'Format' After formatting the 'system reserved partition' will now become normal 'system' partition In fact you install the Windows on the 100MB partition created by windows and you cheat the Windows. This solution is tested on Windows 7 and 8.1. You've got to partition the hard drive first. You can do this from the Windows 7 setup screen that appears after you boot from the Windows 7 DVD. On the First setup screen, that asks you for language settings, Press Shift + F10 . This will open a Command Prompt window. Type diskpart and press Ent
