Chara | Desktop anime characters implemented with JavaFX

I am using Windows.Devices.Bluetooth library in the Windows forms. Communication between devices is fine, but too slow (I get response after ~150 ms with BT 5.2). I think that the problem is with write command (GattCharacteristic.WriteValueAsync()), because the time from calling this command to his executing is more then 100 ms.

Code:

I'm a newbie in coding and I tried to do my own hangman game when I encounter a big bug that I cannot solve. I gotta be honest, I'm not too familiar when it comes to modify list so that might be why I cannot solve this. The following piece of code is a function that takes some parameters and tries to return the modified blankSpaces as a not-so-blank-spaces, so for example if the user tries to guess with ther word "o", but the word is not on the list of the original word, lets say for example "love", the blankSpaces for love would be something like "_ _ _ _", so I'm trying to do that if the letter "o" is inside the original word I would take the position of the original word and replace it on the blankSpaces to return something like "o_" because its on the original string:

I am writing a small application to validate a "candidate" xml file against a "bank" of known good schema files, which are stored in a folder...

Turns out the known good schema files are raising problems themselves!

The way I load the schema files (21 files, I am pretty sure most of these schemas don't only refer to themselves, but some of them use other schemas in the folder) into my "schema space":

I want to get random names from the nameArray and each time delete that element, so that in the end, I have got all names and the nameArray is empty. Nothing displays in the console.

I'm using BluetoothGatt to make communication for BLE device and Android device. I have using the sample code to connect these two devices. But I'm truly stuck on transmitting the data between these two devices.

And my code is as below.

I am new to the database and am following tutorials and doing experiments. So my apology if that question turned out to be stupid.

I set up a table like that:

So I've wrote this code but I can't seem to figure out how to write out the last piece of logic for it to work as desired.

How would you either shift the order of an array or keep the natural order of an array when using the Ruby .uniq method or even .to_set?

So for example:

I would like to create a responsive page that

1. hides the right chat info box when the page is under 1000px wide

and

1. hides both the right chat box and left sidebar when the page is under 600px;

but I can't figure out what is wrong with my code that results in media queries not working.

Also, the searchbox in the left side bar is overflowing its parent even if I add "box-sizing: border" box to it.

The last question is that I would like to make the vertical side borders of the boxes to be the same height as the page height, without creating a side scroll bar (I tried making the boxed height: 100%, which was serviceable but it also created a side scrollbar, which is not allowed in this assignment).

Please have a look at my code below, thanks much:
