After I read the article from Stop Chatting with AI. Start Loops (Ralph Driven Development) from Luke Parker. I have tried the Ralph Driven Development. That is mind-changing. In the past, I have used AI coding before, which is more like programming by chatting. But Ralph Driven Development is to loop the specification, executing the plan item by item. Then the AI agent will build the application without any human interaction. What I need to do is write the plan in very detailed steps, like “Creating User Management Page with CRUD functions, the edit window needs to be a modal window”. I need to write in very detail, like to teach 3 years old child. At the end, I built my home intranet. It has a to-do list and shopping list management. Moreover, I have hooked up with ollama. I can use the chat to access my to-do and shopping items. Of course, it has a full of bugs. I still need to test and debug (although in the plan, I told it to test it).

Luke used OpenCode. For myself, I used kimi, that is relatively lower cost than Claude Code.

My command is

while ($true) { kimi -p "READ all of plan.md Pick ONE task per timesso Verify via web/code search. Complete task, verify via CLI/Test output. Commit change. ONLY do one task. Update plan.md. If you learn a critical operational detail (e.g. how to build), update AGENTS.md. If all tasks done, sleep 5s and exit. NEVER GIT PUSH. ONLY COMMIT." --yes }

That is working well, but it burned the quote very quick

Here is the example

For using the PieChart, that is very easy, you just need to bind the series collection

Then I just need to get the data from my repo:

            var categories = new ObservableCollection(_database.BudgetCategories.GetAllCategories());

            SeriesCollection = new SeriesCollection();
            foreach (var category in categories)
            {
                var budgetItems = new ObservableCollection(_database.BudgetItems.GetItemByCategory(category));
                double amount = 0;
                foreach (var item in budgetItems)
                {
                    amount += (double) item.Amount;
                }
                var pieSeries = new PieSeries
                {
                    Title = category.Name,
                    Values = new ChartValues { new ObservableValue(amount) },
                    DataLabels = true
                };
                SeriesCollection.Add(pieSeries);
            }
         
        }  

Recently, we have been buying a WPF application. That is a budget management application. That is talking about money. Of course, charts need to play an important role. I have looked into various charting libraries. Some of them need to be paid. However, one is entirely open and completed under an MIT license. That does not require access to their AP. Charting is done locally. It supports everything, such as MAUI, Wpf, Winforms, and ASP.net. In addition, the documentation is alright. That is Live Charts.

I found that the ComboBox WPF binding in WPF does not work correctly if the binding value is of an object type. Even when I set SelectedValuePath="Id", the binding fails to set the value. When a different value in the ComboBox is selected, the new selected value should be set in the ViewModel too. However, this does not happen this way.

I got a solution for this issue, which is to set the SelectedValue to be the CategoryId:

<ComboBox Grid.Row="3" Grid.Column="1" 
          ItemsSource="{Binding CategoryList}"
          DisplayMemberPath="Name" 
          SelectedItem="CategoryId"
          SelectedValue="{Binding CategoryId, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
          SelectedValuePath="Id" 
          Margin="5"/>
    

Inside the ViewModel:

public int CategoryId
{
    get => _selectedCategoryId;
    set
    {
        if (_selectedCategoryId != value)
        {
            //_selectedCategory = value;
            _item.CategoryId = value;
            _item.Category = CategoryList.FirstOrDefault(c => c.Id == value);
            OnPropertyChanged();
        }
    }
}
    

Then it will work!
