Answer : Variables declared inside the class definition, but not inside a method are class or static variables: >>> class MyClass: ... i = 3 ... >>> MyClass.i 3 As @millerdev points out, this creates a class-level i variable, but this is distinct from any instance-level i variable, so you could have >>> m = MyClass() >>> m.i = 4 >>> MyClass.i, m.i >>> (3, 4) This is different from C++ and Java, but not so different from C#, where a static member can't be accessed using a reference to an instance. See what the Python tutorial has to say on the subject of classes and class objects. @Steve Johnson has already answered regarding static methods, also documented under "Built-in Functions" in the Python Library Reference. class C: @staticmethod def f(arg1, arg2, ...): ... @beidy recommends classmethods over staticmethod, as the method then receives the class type as the first argument, but I...

Answer : The , at portion of the string is keeping Google Sheets from recognizing it as a datevalue. Just remove it with the substitute function and wrap in datevalue function like so: =DATEVALUE(SUBSTITUTE(A1,", at","")) To format as DD/MM/YYYY just go to custom formatting and set it to look like the following: =DATEVALUE(JOIN("/", LEFT(D5,2), {MID(D5,4,2), RIGHT(D5,4)})) where D5 contains for example: 25.06.2019 which script converts to datevalue: 43641 Dateformat is as dd.MM.YYYY converted to dd/MM/YYYY and then converted to datevalue. Google sheet's documentation helps: DATEVALUE , JOIN , LEFT , MID , RIGHT Datevalue is useful for organizing rows of data by date correctly. Another solution is to create custom function.

Answer : Open the Gemfile and change first line from this source 'https://www.rubygems.org' to this source 'http://www.rubygems.org' remove the ' s ' from ' https '. As @Wasif mentioned, first make sure the Ruby Gems site is up and your network access is ok. If they works fine, try it like this: First, delete your Gemfile.lock file Then run gem update --system Then in your Gemfile try changing the first line source 'https://rubygems.org' to http:// (without an s ) Unless there is a problem with your connectivity this should fix the issue with bundle install .

Answer : You'd need to create an instance of the default theme and use it when defining your own: import { createMuiTheme } from 'material-ui/styles'; const defaultTheme = createMuiTheme(); const theme = createMuiTheme({ typography: { fontSize: defaultTheme.typography.fontSize + 2 } }); export default theme; You can also create your theme and then add on to it after theme is created. import { createMuiTheme } from 'material-ui/styles'; const theme = createMuiTheme(); theme.typography = { ...theme.typography, fontSize: theme.typography.fontSize + 2 } export default theme;

Answer : Simplest way to do this : Right click on your opened project in Android Studio and select New > Module In the left Pane choose Android Library and click on next. Enter all details, untick Create Activity, Theme and all if not required. Choose API level same as your project and Next, Next, Next . Now you will see an another directory inside your project, build.gradle for library will be automatically configured for you. If your module/library name is "mylibrary" , include ':mylibrary' will be automatically added in settings.gradle file inside root directory of your project. Now open your main module and insert this line in dependency block : compile project(':mylibrary') If you want to use same library in other projects, you have to copy the library module to that particular project using File Explore and have to configure settings.gradle and main module's build.gradle manually. An old question, but even now there d...

Answer : This is almost certainly due to you having DOCTYPE html in your html file. If you do, then you need to ensure that the grids container has a non-0 height to fill, otherwise it will appear as a flat line as you've found. This is not an ag-Grid specific issue - it's a side effect of not having quirks mode in use. The easiest thing for you to do is this: <style> html, body { width: 100%; height: 100%; } This StackOverflow Question/Answer explains the underlying issue pretty well You shall try setting the autoHeight of the ag-grid, by setting the DomLayout . See the sample code below for angular. onGridReady(params) { this.gridApi = params.api; this.gridColumnApi = params.columnApi; //The ag-grid is not enlarging based on the page height, //so dynamically adjusting the height of the grid this.gridApi.setDomLayout("autoHeight"); } For reference see this https://plnkr.co/edit/Jb1TD7gbA4w7yclU?prev...

Answer : As of latest version of Sequelize (i.e. 3.3.2 ), authenticate can be used to check the connection: var sequelize = new Sequelize("db", "user", "pass"); sequelize.authenticate().then(function(errors) { console.log(errors) }); authenticate simply runs SELECT 1+1 AS result query to check the db connection. UPDATE : Errors by the newest API need to be handled in catch : sequelize .authenticate() .then(() => { console.log('Connection has been established successfully.'); }) .catch(err => { console.error('Unable to connect to the database:', err); }); UPDATE 2 : I haven't tested this, but its only logical that the same thing can be reached with async/await : try { await sequelize.authenticate() } catch (err) { console.error('Unable to connect to the database:', err) } You won't see errors, like password authentication errors, in .then . From the sequelize documentation here: ...

Answer : Minecraft officially supports ASCII characters under 0x80. It can render more characters, but they do not render correctly. The supported characters are listed below. !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_'abcdefghijklmnopqrstuvwxyz{|}~⌂ÇüéâäàåçêëèïîìÄÅÉæÆôöòûùÿÖÜø£Ø׃áíóúñѪº¿®¬½¼¡«» You can find this list together with more info about the possibilities( colors, and style) of the chat at the Chat article on the MinecraftCoalition wiki, if figuring out what these characters are is too much trouble. Minecraft chat now accepts 255 characters (a few still do not render correctly). Navigate to the Font section of the Wiki page and click expand to see the full list. The current answer by Krael is out of date and wrong: even the old version contained several characters outside of ASCII. ASCII does not contain accented characters. Instead, Minecraft used to support windows-1252. There are 256 code points in it, of which ...

Answer : I faced the same problem. I have fixed out by going to Setting -> Compiler -> Global Compiler Settings -> Toolchain Execuatables (tab) . There, click on Program Files and then rename C compiler to gcc.exe and C++ compiler to g++.exe . I know this is an old question but let me see if I can help. First of all, on the download page make sure you downloaded codeblocks-13.12mingw-setup.exe and NOT codeblocks-13.12-setup.exe. Of course the version numbers may change but pay attention to the name. Then after installing codeblocks, go to Settings->Compiler->Toolchain executables. From here, change the C compiler to gcc.exe and C++ compiler to g++.exe. Hope this helps anyone else going through this problem :-)

Answer : It seems that you're using CSS3 transition for doing this. The easiest way to do this is to set delay manually: $("#card1").removeClass('flip'); setTimeout(function(){ //wait for card1 flip to finish and then flip 2 $("#card2").removeClass('flip'); }, 500); setTimeout(function(){ //wait for card2 flip to finish and then flip 3 $("#card3").removeClass('flip'); }, 1000); There's no built in jQuery method to check that css transition is complete.
