Example 1: map arduino Syntax map ( value , fromLow , fromHigh , toLow , toHigh ) Parameters value : the number to map . fromLow : the lower bound of the value’s current range . fromHigh : the upper bound of the value’s current range . toLow : the lower bound of the value’s target range . toHigh : the upper bound of the value’s target range . Example : map ( val , 0 , 255 , 0 , 1023 ) ; Example 2: arduino map function long map ( long x , long in_min , long in_max , long out_min , long out_max ) { return ( x - in_min ) * ( out_max - out_min ) / ( in_max - in_min ) + out_min ; }

Answer : I found the solution. The reason is that Windows Hello is managed differently on domain joined computers, starting with the anniversary update. To get it to work you have to follow these steps: 1) Setup a Group Policy Central Store (you should already have that) 2) Get Windows 10 Anniversary Update Group Policy Templates . You can do so by copying your files from PolicyDefinitions (in windir on a Win10 Anniversary Update machine) into the PolicyDefinitions of the central store. You might copy those files first to a file share, because of permissions your regular user should not have on the central store. 3) Setup a new GPO or add to an existing the following settings to enable Windows Hello: Computer Configuration/Policies/Administrative Templates .../Windows Components/Windows Hello For Business/ Use biometrics => Enabled .../Windows Components/Windows Hello for Business/ Use a hardware security device => Enabled (if you want to use TPM instead of k...

Answer : You don't need this line at all. Just remove it and switch your Python interpreter to point to the one within your venv . Here's a relevant documentation (italicized emphasis mine): To select a specific environment, use the Python: Select Interpreter command from the Command Palette ( Ctrl + Shift + P ). ... and opening a terminal with the Terminal: Create New Integrated Terminal command. In the latter case, VS Code automatically activated the selected environment. Once you switch the interpreter VS code should create a .vscode folder within your workspace with a settings.json indicating the python interpreter. This will give VS code the direction of where to locate the venv . This is how I did it in 2021: Enter Ctrl + Shift + P in your vs code. Locate your Virtual Environment: Python: select interpreter > Enter interpreter path > Find Once you locate your virtual env select your python version: your-virtual-env > b...

Answer : You could try this: @Html.DropDownList("country", new SelectList(ViewBag.countries), "-select- ", new { @class="chzn-select", @style="width:160px;" }) In your collection ViewBag.Countries just insert a dummy record at the from of the collection with the name "-select-". You should be able to force the selected item with an alternate constructor like this: @Html.DropDownList("country", new SelectList(ViewBag.countries as System.Collections.IEnumerable, "name", "name", "-select-"), new { @class="chzn-select", @style="width:160px;" } ) A quick and (not so) dirty solution involving jQuery. Instead of adding a dummy item at the start of the list, prepend a new option that is disabled. The main advantage is that you don't have to mess with a dummy item in your list , and most important, you won't be able to select that dummy item in the page : ...

Answer : There's no casting in javascript, so you cannot throw if "casting fails". Typescript supports casting but that's only for compilation time, and you can do it like this: const toDo = <IToDoDto> req.body; // or const toDo = req.body as IToDoDto; You can check at runtime if the value is valid and if not throw an error, i.e.: function isToDoDto(obj: any): obj is IToDoDto { return typeof obj.description === "string" && typeof obj.status === "boolean"; } @Post() addToDo(@Response() res, @Request() req) { if (!isToDoDto(req.body)) { throw new Error("invalid request"); } const toDo = req.body as IToDoDto; this.toDoService.addToDo(toDo); return res.status(HttpStatus.CREATED).end(); } Edit As @huyz pointed out, there's no need for the type assertion because isToDoDto is a type guard, so this should be enough: if (!isToDoDto(req.body)) { throw new Error("invalid...
