Consider the following code: public async Task MethodA() { await MethodB(); // Do other work } public async Task MethodB() { await MethodC(); // Do other work } public async Task MethodC() { // Or await some other async work await Task.Delay(100); } ...

It parses the data from the %%GLOBAL_ConversionCode%% template variable, and as such this script should be inserted in order.html immediately after the %%GLOBAL_ConversionCode%% variable. This was originally intended for the Blueprint theme framework and, as such, may not work on Stencil. <scrip...

Now you can start writing your own go code with auto-completion using Atom and Gulp: package main import ( "fmt" "mypackage" ) func main() { println("4! = ", mypackage.Factorial(4)) }

Enumerating through Keys foreach ($key in $var1.Keys) { $value = $var1[$key] # or $value = $var1.$key } Enumerating through Key-Value Pairs foreach ($keyvaluepair in $var1.GetEnumerator()) { $key1 = $_.Key1 $val1 = $_.Val1 }

The code below shows how to perform asynchronous navigation when the app is in a MasterDetailPage context. public async Task NavigateMasterDetail(Page page) { if (page == null) { return; } var masterDetail = App.Current.MainPage as Mas...

ZeroR is a simple classifier. It doesn't operate per instance instead it operates on general distribution of the classes. It selects the class with the largest a priori probability. It is not a good classifier in the sense that it doesn't use any information in the candidate, but it is often used as...

In order to build a good classifier we will often need to get an idea of how the data is structered in feature space. Weka offers a visualisation module that can help. Some dimensions already seperate the classes quite well. Petal-width orders the concept quite neatly, when compared to petal-widt...

Trees can build models that work on independent features and on second order effects. So they might be good candidates for this domain. Trees are rules that are chaind together, a rule splits instances that arrive at a rule in subgroups, that pass to the rules under the rule. Tree Learners generate...

You can get your working folder by calling the method getFilesDir() on your Activity (Activity is the central class in your application that inherits from Context. See here). Reading is not different. Only your application will have access to this folder. Your activity could contain the following c...

Bullet This one particularly blew my mind. The bullet gem helps you kill all the N+1 queries, as well as unnecessarily eager loaded relations.
