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 )

I must be the only person who didn't like it. I tried 2 times to read it and each time I gave up after having read one third. I felt this book did not age well. May be I will try to read it again one day and find out why it is a great book.

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.

Sometimes I know that the problem is very simple (probably a > instead of a >=) but I can't find it and wonder why they pay me when I cannot even solve this simple issue. Sometimes I solve an very complex issue (e.g. a value changed by an electromagnetic coupling) and wonder why I am not paid more.

Merci. Je pensais être le seul à haïr ce livre (même ado l'idéologie décrite me répugnait). Quand on en a tiré une bd (parue chez Glenat) je me suis dit qu'une version plus moderne corrigerait les erreurs du roman mais (selon les critiques (je n'ai pas lu la bd)) la bd semble très fidèle au roman.
