hads | : books : Markdown superpowered documentation for Node.js

I am upgrading my application from Angular 8 to 9. I used the below command.

My program is supposed to guess a number. First, the user guesses a number (in their head) and doesn't tell the computer. Then, the computer starts to guess the number. The user sees the number the computer guessed and sends one of three types of string:

• 'c' means correct and finish
• 'b' means bigger number
• 'l' means lower number.

I have a problem: when the system guesses the number it takes too long to find the answer because range of random doesn't change in the program. Can somebody help me improve the code to become more efficient?

Short: In my c++ project i need to read/write extended file properties. I managed it with using alternate data streams (ADS). My problem is, for opening the ADS i need to use the CreateFile API. But it is not fulfilling my needs. NtCreateFile will fullfill all my needs. (Or alternatively NtSetEaFile and NtQueryEaFile) But NtCreateFile is not directly accessible from a win32 console application.

I know i can use this function easily via GetProcAdress. But i like to know the opinion of you all, if i did miss something? Some other libs are using this pattern already, for example Chromium (https://github.com/chromium-googlesource-mirror/chromium/blob/1c1996b75d3611f56d14e2b30e7ae4eabc101486/src/sandbox/src/win_utils.cc function: ResolveNTFunctionPtr) But im uncertain, because the c++ project is not a hobby project and i ask myself if it is dangerous or not.

I guess NtCreateFile is maybe the securest way to do, because it is well documented and supported by winternl.h header. Especially because this method is unchanged since windows 2000. But what is with NtSetEaFile, NtQueryEaFile which are fitting my needs perfectly. They are only half documented. A documentation for ZwSetEaFile and ZwQueryEaFile exist (unchanged since windows 2000).

Reason why i want to do that:

I want to write and read extended properties from files via ADS. But in case of writing the extended property of a given file the first time, i need to open the file with OPEN_ALWAYS. In case of file is not existing it will create a new file, even if i only access not the content stream of the file. To avoid this i get first the handle of the original file and check with this HANDLE if the file still exist. But i dont want to blog any file with reduced access rights, because from my point of view that is a very bad pattern. The user needs to have full access to any file any time. Because of that we open all HANDLES with the flag FILE_SHARE_DELETE | FILE_SHARE_READ | FILE_SHARE_WRITE. And now i have the race.

So i'm looking at building an app to control my 3d printer. I will say something such as "tell me how long is left to print" the app will then go to my server which will issue a GET request to to the printer and and return a response which will be spoken over my smart speaker.

All the tutorials I have found mention Dialogflow which is a paid service.

Do I actually need it? I'm not afraid to get my hads dirty if it is just a case of slinging some code together.
