42 days to go!!! So happy with how the cover turned out, posting a making-of soon! Pre-order available in most book stores: linktr.ee/adhdalien
The ADHD alien character is surrounded by swirls, sparkles and daily life objects such as a clock, homework papers, pencils, keys and a phone.

I am making quite good progress with my multiplayer Snake game. But as usual there are some strange race conditions that on rare occasions cause unexpected behaviour.

Now that was unexpected. There are similarities between #Haibane Renmei and #TADC (Some people have noticed the parallel between Rakka and Ponmi but I think there are also similarities between Jax and Reki )
Rakka just arrived in Haibane community having forgotten her name and asking Why MePonmi Just arrived in the Digital Circus having forgotten her name and asking Where am I?

This is how to implement a viewmodel in #WPF (I am pretty sure I will need this post to remind me how to do it the next time I try to implement MVVM)
class MainViewModel: INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }

    private string _txt1 = "";
    public string txt1
    {
        get => _txt1;
        set
        {
            if (value != _txt1)
            {
                _txt1 = value;
                OnPropertyChanged(nameof(txt1));
            }
        }
    }

@microsoft.com please solve this issue. This is becoming ridiculous that official google development tools are blocked. And the way to avoid the blocking explained by your own A.I. copilot gives useless solution.
'C:\devtools\gotools\gopls.exe' was blocked by your organization's Device Guard policy.
