Declaring variables for Android widgets is very repetitive. This Ruby script generates the code that can be copy-pasted into onCreate. Use Android Studio (Cmd+Option+F) to refactor the variables into member variables. #androidLayoutToVars.rb require 'nokogiri' class LayoutProcessor < Nokogiri::XML::SAX::Document def start_document end def start_element(name, attrs=[]) attrs = attrs.to_h if attrs.key?('android:id') varName = attrs['android:id'][5..] declaration = "#{name} #{varName} = findViewById(R.id.#{varName});" puts declaration end end def end_element(name) end def end_document end end parser = Nokogiri::XML::SAX::Parser.

Let’s say we have an array of strings like this: vals1 = ["A", "B", "C", "D"] We want to run the array through a map function to get the structure: [ { _id: 'A' }, { _id: 'B' }, { _id: 'C' } ] …and so we try writing a map function like this: vals2 = vals1.map(e => {_id: e}) //Returns: [ undefined, undefined, undefined ] It seems odd at first, but Javascript interprets the squiggly brackets as a function, so the executing code looks something like this:

This post is an example of the RecyclerView in Android. package com.pockettheories.todoone; import androidx.annotation.NonNull; import androidx.appcompat.app.AppCompatActivity; import androidx.recyclerview.widget.LinearLayoutManager; import androidx.recyclerview.widget.RecyclerView; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ArrayAdapter; import android.widget.Button; import android.widget.EditText; import android.widget.LinearLayout; import android.widget.TextView; import android.widget.Toast; import java.util.ArrayList; import java.util.List; public class MainActivity extends AppCompatActivity { RecyclerView rvu; Button btnAdd; EditText txtNewItem; List<String> strValues = new ArrayList<String>(); //List.of("A", "B", "C", "D", "E"); RecyclerView.Adapter adapt; @Override protected void onCreate(Bundle savedInstanceState) { super.

HarperDB provides a REST API at the endpoint localhost:9925. Commands are sent in JSON format as an HTTP request body. Creating a schema and a table, and inserting data: {operation: "create_schema", schema: "hr"} {operation: "create_table", schema: "hr", table: "employee", hash_attribute: "empno"} {operation: "insert", schema: "hr", table: "employee", records: [{empno: 1, name: "Nitin"}]} Fetching data {operation: "search_by_hash", "schema": "hr", table: "employee", hash_values: [1], get_attributes: ["name"]} {operation: "search_by_hash", "schema": "hr", table: "employee", hash_values: [1], get_attributes: ["*"]} {operation: "search_by_value", schema: "hr", table: "employee", search_attribute: "name", search_value: "Nit*", get_attributes: ["*"]} {operation: "sql", sql: "UPDATE hr.

String concatenation is almost never the right answer when passing a parameter to an SQL query. For example, this is a bad idea: sqltxt = "SELECT * FROM dept WHERE dname = '#{params['dname']}' " @results = ActiveRecord::Base.connection.execute sqltxt Replace it with a parameterized query like this: sqltxt = "SELECT * FROM dept WHERE dname = ?" @results = (ActiveRecord::Base.connection.raw_connection.prepare sqltxt).execute params['dname'] Adding some more code around the logic… sqltxt = "SELECT * FROM dept WHERE dname = ?
