You cannot compare two different objects using includes in javascript, because includes uses ===. Only references to the same object will return true using ===. You'll need to write a custom function that runs through all of the keys of your object and compares their values between your two arrays.

This article explains some techniques for comparing two objects: https://dmitripavlutin.com/how-to-compare-objects-in-javascript/

Multiple requests causing program to crash (using BeautifulSoup)

Asked 2021-Jun-15 at 19:45

I am writing a program in python to have a user input multiple websites then request and scrape those websites for their titles and output it. However, when the program surpasses 8 websites the program crashes every time. I am not sure if it is a memory problem, but I have been looking all over and can't find any one who has had the same problem. The code is below (I added 9 lists so all you have to do is copy and paste the code to see the issue).

Region eu-west-2 not available for aws module boto.ec2 latest

Asked 2021-Jun-15 at 15:39

I'm running boto with python3 and I'm running an ansible playbook to setup some ec2 instances. Everything is fine, creating instances, security groups, key pairs, everything in eu-west-2. When the task for Elastic IPs runs it fails with this message: Region eu-west-2 does not seem to be available for aws module boto.ec2. If the region definitely exists, you may need to upgrade boto or extend with endpoints_path

I'm running ansible with -e ansible_python_interpreter="/usr/bin/python3". I have latest boto installed.

I resorted to using the community module for elastic ip. So community.aws.ec2_eip instead of ec2_eip.

QUESTION

Calculate percentage of HIV cases in different US States using R

Asked 2021-Jun-15 at 14:40

I am having a dataset which contains the absolute HIV cases of four US State over 2 years.

There are three columns date (Jan 2018, Feb 2018 ...) , state (CA, NY, FL, MA) , and abs_cases in the data frame. I am ignoring the population changes in those 2 years in the respective states.

I now want to calculate the relative cases for each state using the population for each state which I googled. (I will just use fantasy numbers here) pop<- "CA"= 11111, "NY"= 22222, "FL"= 33333,"MA"= 444444.

I already tried using

ANSWER

Answered 2021-Jun-15 at 14:40

Without an example dataset, here is my guess at what you are trying to do. You can convert pop into a dataframe using enframe and join it to df by state. Then, you can compute the cases per population by each State in each month.

ANSWER

Answered 2021-Jun-15 at 13:26

While editing my initial question to add more context as Jay proposed I think it found the issue.

What probably happens? The view where the crash is, contains a table view. Each cell will be configured before being presented. I use a flag which holds the information, if the amount of weight for this cell (it is a strength workout app) has been initially set or is a change. When prepareForReuse is being called, this flag has not been reset. And that now means scrolling through the table view triggers a DB write for each reused cell, that leads to unnecessary writes to the db. Unnecessary, because the exact same number is already saved in the db.

My speculation: Scrolling fast could maybe lead to a race condition (I have read something about that issue with realm) and that maybe causes this weird crash, because there are multiple single writes initiated in a short time.

Solution: I now reset the flag on prepareForReuse to its initial value to prevent this misbehaviour.

The crash only happens when the cell is set up and the described behaviour happens. Therefor I'm quite confident I fixed the issue finally. Let's see. -- I was not able to reproduce the issue, but it also only happens pretty rare.

Here I'm wondering about the line [in s_client]
New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES256-GCM-SHA384

You're apparently using OpenSSL 1.0.2, where that's a basically useless relic. Back in the days when OpenSSL supported SSLv2 (mostly until 2010, although almost no one used it much after 2000), the ciphersuite values used for SSLv3 and up (including all TLS, but before 2014 OpenSSL didn't implement higher than TLS1.0) were structured differently than those used for SSLv2, so it was important to qualify the ciphersuite by the 'universe' it existed in. It has almost nothing to do with the protocol version actually used, which appears later in the session-param decode:

Can't collect price from a webpage using vba/selenium in headless mode

I've created a vba script in combination with selenium to scrape price $8.97 from this webpage. The script does fetch the content if I run it in non-headless mode. However, my intention is to grab the content in headless mode. I know I can use their api to fetch the price but the very api gets blocked after 4/5 requests, so I intentionally chose this route.

What is the correct way to simplify a xnor

Asked 2021-Jun-14 at 21:06

I was reading over a resource https://www.mi.mun.ca/users/cchaulk/misc/boolean.htm and I noticed the xnor simplification seems to have mixed outputs.

15a, 15b, 15c are all focusing on xnor but only 15b seems to be correct when I attempt to check.

For reference:

ANSWER

Answered 2021-Jun-14 at 21:04

15b is the definition of XNOR in conjunctive normal form. 15c is the negation of XNOR (i.e., XOR) in disjunctive normal form. You can derive this using De Morgan's laws, which state

'(XY) == 'X + 'Y
'(X + Y) == 'X'Y

Using these laws, we can first write 15b
