Create Windows bootable USB with macOS

If you need to create a Windows 10 installation USB key using a macOS, you can use these commands to do it simply.
This procedure deletes all data from the USB stick, so be careful 🙂

Open Terminal and use the following commands

diskutil list
diskutil eraseDisk MS-DOS "WIN10" GPT <USB disk>
hdiutil mount <path to the Windows 10 ISO file>
cp -rp /Volumes/<ISO mounting point> /Volumes/WIN10
hdiutil unmount /Volumes/<ISO mounting point>
hdiutil unmount /Volumes/WIN10

About autonomous driving

In these days I’m driving an Infiniti Q30, I find it very pretty and even if it has the wrong wheel drive, it can be fun too 🙂

One of the things I like best about this machine is electronic stuff. One of the driving aids I noticed is the autonomous reading of the road signs. I found the thing interesting also because I immediately looked at it from the standpoint of autonomous driving. Right about this context yesterday I noticed something that I did not like. Passing behind a tourist bus I noticed that the car read as a speed limit, as reported by the heavy vehicle that preceded me in a sticker that reported its maximum speed on the highway. In the picture you can see little because I was driving and I took it at a run. However, you can guess what happens: the car signals me as a speed limit of 80 km / h (instead of the 50 real ones) because the coach in front has a sticker that indicates its maximum speed on the highway in 80 km / h.

I noticed this behavior on several occasions between yesterday and today.

Today this is not a big problem, I guide and I know the limits and I know what directions to follow. But if she were driving, wouldn’t it be too easy to deceive her? And in the case of autonomous driving, any fines, who should pay them? Who was in the car? No, he wasn’t driving! The owner? No, he didn’t even drive! The manufacturer of the vehicle? Who hadn’t passed a patch in time?

I leave you with these doubts and with the invitation to use the right pedal until we can do it 🙂

Wait for an event in a WaterfallDialog

Working on a Skill, I needed to block the execution of a WaterfallDialog while waiting for a specific event to arrive.
The solution is simple and based on the use of EventPrompt. Below I show how to use it.

Register EventPrompt in the constructor

AddDialog(new WaterfallDialog(nameof(WaterfallDialog), new WaterfallStep[]
{
	HelloAsync,
	WaitForEventAsync,
	DoneAsync
}));

AddDialog(new EventPrompt(nameof(EventPrompt), "SampleEvent", Validate));

InitialDialogId = nameof(WaterfallDialog);

Implement the three dialog steps

private async Task<DialogTurnResult> HelloAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{
	await stepContext.Context.SendActivityAsync(MessageFactory.Text("Hello :)"), cancellationToken);

	return await stepContext.NextAsync(cancellationToken);
}

private async Task<DialogTurnResult> WaitForEventAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{
	return await stepContext.PromptAsync(nameof(EventPrompt), new PromptOptions { Prompt = MessageFactory.Text("Waiting for the event") });
}

private async Task<DialogTurnResult> DoneAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{
	await stepContext.Context.SendActivityAsync(MessageFactory.Text("After I receive the event."), cancellationToken);

	return await stepContext.NextAsync(cancellationToken);
}

Implement the event validator

async Task<bool> Validate(PromptValidatorContext<Activity> promptContext, CancellationToken cancellationToken)
{
	var activity = promptContext.Recognized.Value;
	if (activity.Type == ActivityTypes.Event)
	{
		try
		{
			string eventValue = (string)activity.Value;
			
			if(eventValue == "OK")
			{
				return true;
			}
		}
		catch { }
	}

	return false;
}

macOS disable WIFI on logout

I recently started using an Apple notebook as a development laptop. I realized that when I block the screen the WIFI connection goes down. This is a wanted behavior and can be changed using this command:

cd /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources
sudo ./airport en1 prefs DisconnectOnLogout=NO

Obviously you need to replace “en1” with the identifier of your WIFI interface.
