nibble | QMK firmware files for NIBBLE keyboard | Keyboard library

I need to convert a UUID (like ffffffff-ffff-ffff-ffff-ffffffffffff) to a number with as least digits as possible. These UUIDs are being generated by com.fasterxml.uuid.impl.TimeBasedGenerator.java.

When trying to write some routine in x86 assembly for a boot loader, I came across a bug where when a division error happened, the program would get stuck in an infinite loop. Through investigating, I found out that calling int 0 would go through the exception handler normally and then continue execution of the rest of the program. Writing my own exception handler for x86, the return address when a division error exception happened was the address of the instruction, meaning that it would just execute the division over and over looping forever. Is this normal behavior or a bug with Virtualbox/my cpu specifically?

I have a data model like this picture below and all of them are in the same collection, but of course are different in data structure. I used the manual references in document movies and document studios. For example, like the code below:

• For document people

  { "_id": 100600, "first_name": "Becka", "last_name": "Battson", "birth_day": "2001-10-03" }

• For document movies

  { "_id": 1100, "title": "Tom and Jerry", "director_id": 100100, "release_year": 2018, "imdb": { "rating": 4.8, "votes": 100 }, "actors": [ { "person_id": 100300, "as": "Tom" }, { "person_id": 100400, "as": "Jerry" }, { "person_id": 100500, "as": "Nibbles" } ] }

• For document studios:

  { "_id": 9991000, "name": "Walt Disney", "year_founded": 1923, "movies": [ 1100, 1200 ], "headquarters": { "address": "1375 E Buena Vista Dr", "city": "New York", "state": "New York", "country": "US" } }

I have some tasks that need join between 2 documents together to get data. For example, "Indicates that the movies have the actor has the last name "Battson" . But I know that MongoDB doesn't support join documents like joining 2 tables in RDBMS.

I have tried to used this code below in MongoDB shell but it doesn't make sense. I think I need to get the values from the _id in the result query, then push them into the array array_idActor so that the second code can run:

I was thinking about parsing a list of integers (from a property string). However, I would like to go beyond just positive and negative decimal values and parse any string that indicates a Java integer literal (JLS 17) as can be found in source code. Similarly, I would like to be lenient with regards to any prefixes, separators and appendices around the integers themselves. In other words, I want to find them using repeated calls to Matcher.find().

Is there a regular expression that matches all possible Java integer literals? It doesn't need to check the upper and lower bounds.

Even though I did explicitly link to the JLS, I'll show some valid and invalid numbers:

• -1: the 1 is matched, but the minus is an unary operator (I'll adjust if necessary)
• 0x00_00_00_0F: the value fifteen is matched as hex digits, with an underscore to separate the two nibbles
• 0b0000_1111: the value fifteen in binary is matched
• 017: the octal value of fifteen is matched

I'm experimenting with the new C++ 2020 std::format function. I would like to represent the output with a width deduced from its type. Currently I have this line:

My program tries to decrypt the data of a file by writing the file to a buffer, manipulating the buffer data, then writing the buffer to a new output file. Currently this program does not manipulate the data inside the buffer, it just writes the buffer data to the output file as is. What would be the correct way to write the manipulated data from my buffer into a new file?

Can anyone assist with my understanding of these directions? I'm currently learning x86 Assembly, but I cannot seem to display the output I'm looking for. I understand AL contains the byte I need to display..but how can I display the correct output, considering these requirements:

I am getting stuck on WriteChar for DH and DL, as the output I'm looking for with my solution does not appear to be correct...I can't tell what I'm missing. I can initialize AL and DL/DH correctly, but when I use WriteChar, it prints a completely different character.

1. store in the register DH the ASCII code of the most significant nibble.
2. store in the register DL the ASCII code of the least significant nibble.
3. Display (using WriteChar) on the console the character stored in DH (recall that WriteChar uses AL for the character to display).
4. Display (using WriteChar) on the console the character stored in DL.
5. Display ‘h’ to indicate that the number is a hexadecimal number.
6. ‘Display’ the ‘line feed’ character (ASCII code is 0Ah) to go to the next line.
7. ‘Display’ the ‘carriage’ character (ASCII code is 0Dh) to go to the next line.

Here is an example and below that is what I have so far...

Example : If AL contains the number 94h, your program 1) must store 39h (ASCII code of the character ‘9’) in DH , 2) must store 34h (ASCII code of the character ‘4’) in DL, 3) must display the characters ‘9’, ‘4’, ‘h’, ‘linefeed’, and ‘carriage return’.

Simple question as title says. I saw some questions on StackOverflow(and in internet) about use cases of nibbles, but I don't understand why do we need to use nibbles. I mean byte is the smallest unit of memory in computing so performing operations on it to manipulate half of it does not seem to be efficient. for example there is article on GeeksForGeeks about swapping nibbles in byte. So if there is need of such thing as nibble why it is not defined as data type(like byte or int or any other) in any nonarchaic programming language?

I know history of bits, nibbles or bytes. Also read wikipedia articles and googled lots of stuff to find the answer on my question, but I was not able to. Maybe this will mark as opinion based and closed but I just wanna have some discussion about this topic, I don't know other good place to ask the same question, so please be kind.

I'm using Django and trying to get javascript to add a hidden field and then pass it to a view try to process the value.

When I hard code the hidden field using the following in my template:
