kandi X-RAY | rubix Summary
RubiX is a light-weight data caching framework that can be used by Big-Data engines. RubiX uses local disks to provide the best I/O bandwidth to the Big Data Engines. RubiX is useful in shared storage architectures where the data execution engine is separate from storage. For example, on public clouds like AWS or Microsoft Azure, data is stored in cloud store and the engine accesses the data over a network. Similarly in data centers Presto runs on a separate cluster from HDFS and accesses data over the network. RubiX can be extended to support any engine that accesses data using Hadoop FileSystem interface via plugins. There are plugins to access data on AWS S3, Microsoft Azure Blob Store and HDFS. RubiX can be extended to be used with any other storage systems including other cloud stores. Check the User and Developer manual for more more information on getting started.

QUESTION
I am working on a program that will count how many years will it take for 6M + 5 each day to solve a rubix cube. Here is my code so far:
...ANSWER
Answered 2021-Nov-26 at 01:10If your function only does cubers += 5, then i don't think its needed. but to answer your question, if you want to modify a variable that is in the outer function nest, you have to declare it in the inner nest as nonlocal first.

QUESTION
I've recently been trying to learn about hash-tables so i can load in lines from a .dat file. This is to reduce the number of times i spend looking through the document for certain lines. After looking through some forums, tutorial-sites and youtube videos i drafted the code seen below.
My problem so far is saving the lines from the .dat to the hash-table with void fileread(char *FILE_NAME), when I print the table I get jibberish. As far as I can tell the code I got basically just saves pointers, so in the end all pointers point to the same arraychar svaret[MAX_LIST]={};, which I've tried to make to both a 2D array and a global variable, non of of which worked. I think i know what's wrong, but i don't really know how to fix the problem. Do i have to write another type of hash code?
ANSWER
Answered 2020-May-15 at 04:03You more or less give the answer in the question:
As far as I can tell the code I got basically just saves pointers, so in the end all pointers point to the same array
The pointer you save is a pointer to from_file from the function fileread (i.e. defined like move_info from_file;).
This is wrong. Never save (or return) pointers to variables that are local to a function. These variables end their life once the function returns. So you have a pointer to a "dead" variable.
In your case you need dynamic allocation. A dynamic allocated variable will "stay alive" until you decide that it's not need any longer (and then you call free).
To use dynamic allocation you need something like:

I'm coding a bot in python for discord using atom and whenever I run a command on my bot (including help) it sends multiple responses to the command, not all of the responses are the same (e.g: s?ping it will answer multiple times with different ping). I think the amount it sends is random and i'm not sure what's wrong with it at all, i've heard that looping does this but i only have one loop and that's to change the status. This is my code (without the token):
