Crumbling large graphs into connected components. Abstract—Finding connected components is a fundamental task in applications dealing with graph analytics, such as social network analysis, web graph mining and image processing. The exponentially growing size of today’s graphs has required the definition of new computational models and algorithms for their efficient processing on highly distributed architectures. In this paper we present CRACKER, an efficient iterative MapReduce-like algorithm to detect connected components in large graphs. The strategy of CRACKER is to transform the input graph in a set of trees, one for each connected component in the graph. Nodes are iteratively removed from the graph and added to the trees, reducing the amount of computation at each iteration. We prove the correctness of the algorithm, evaluate its computational cost and provide an extensive experimental evaluation considering a wide variety of synthetic and real-world graphs. The experimental results show that CRACKER consistently outperforms state-of-the-art approaches both in terms of total computation time and volume of messages exchanged.

QUESTION
What I am trying to do is on button press I will add 4 text elements, each text element in its own cell; beneath its corresponding column. Eg. "Name" column will have the name of the product beneath it. Refer to picture attached below.
My problem is - On button press my 4 elements are created but only one cell is created and it has all 4 of my elements in it. If someone could help me find the solution that would be amazing!
Relevant code attached below.
...ANSWER
Answered 2021-May-06 at 11:38I got the problem all solved!
Just had to create the cell variable inside the forEach loop, so now it will loop through and create a cell each time- then add my textNode to that cell. If anyone has any pointers or alternate solutions more than happy to hear!

You are missing windres, so you need the package that contains it.
To look for it, use cygcheck

These are the grocery store lists:
...ANSWER
Answered 2021-Apr-26 at 13:06Make sure you are using item.lower() and not item.lower. I would also use a dictionary, where the key is the name of the aisle, and the value is a list of items in that aisle.

main(length, 0, [])

Answered 2021-Apr-10 at 03:32The problem is that you call the recursion from the same variables sometimes.
Look at this part of the code:
QUESTION
import zipfile
import itertools
import string
from threading import Thread
def crack(zip, pwd):
try:
zip.extractall(pwd=str.encode(pwd))
print("Success: Password is " + pwd)
except:
pass
zipFile = zipfile.ZipFile("/Users/Yamakasi/Desktop/PY/Mat1.zip")
myLetters = string.ascii_letters + string.digits + string.punctuation
for i in range(1, 1):
for j in map("".join, itertools.product(myLetters, repeat=i)):
t = Thread(target=crack, args=(zipFile, j))
t.start()
ANSWER
Answered 2021-Feb-12 at 10:35The problem is with your external for loop. It doesn't run at all.
range(i, j) runs from i to j-1 so range(1, 1) will run from 1 to 0 which means don't run at all.
QUESTION
Using the w3schools.com SQL tutorial Northwind database, I'm trying to display the category that has the most products shipped. Additionally, I want to display the net income from all sales in that category. I can't figure out how to take the category with the most products shipped, and use the amount of products shipped to calculate the net income of that category. This is because there are many different products that have the same CategoryID but different prices.
...ANSWER
Answered 2021-Jan-25 at 07:24So first of all you get the income for each product and category and then based on that you find total income for that category and you do this with the help of subquery, then you join this resultant table with the category table and with the help of group by you find the product count and total income for each category, below is the sql query for more indepth understanding

QUESTION
I am making a multiprocess for a password cracker and the last time I ran it my computer literally died. Is there any way I can prevent that from happening? I amount of memory it used reached 100% and my computer froze up. I need to run multiple processes to allow different programs to test part of the guesses at a time. This would work if I had more memory, but if anyone has any solutions, please say so.
...ANSWER
Answered 2020-Dec-09 at 15:27For one thing, the variable comb is an extraordinarily long list, and you are passing pieces of this extraordinarily long to each of your subprocesses. This is probably where all of your memory is going.
It would probably be smarter to use a thread pool of some size, and create multiple pieces of work based on the first two letters of the text. Then each worker would generate all the passwords with those first two letters (as a generator, not as a fully fleshed out list) and see what they find. You will find you don't need much memory at all.
Here is a brief outline, breaking up only on the first character.
