AMQPS Symfony Messenger and Heroku

Asked 2022-Mar-03 at 19:15

I’m using CloudAMQP though Heroku’s add-on (https://elements.heroku.com/addons/cloudamqp) with the « Little Lemur » plan. I’m building a PHP Symfony application and I want to connect to AMQP through SSL but it says in the documentation that :

If you want to use TLS/SSL encrypted AMQP, you must also provide a CA certificate. Define the certificate path in the amqp.cacert PHP.ini setting (e.g. amqp.cacert = /etc/ssl/certs) or in the cacert parameter of the DSN (e.g amqps://localhost?cacert=/etc/ssl/certs/). » (https://symfony.com/doc/current/messenger.html#amqp-transport)

My issue is that I have no idea where is located the cacert file on Heroku.

Can you help me with this please ?

ANSWER

Answered 2022-Mar-03 at 19:15

I've found the solution, for those who wants to know how to deal with it on Heroku : you need to download the root CA of CloudAMQP (https://www.cloudamqp.com/docs/faq.html#how-do-i-authenticate-the-identity-of-your-server-tls-certificates) and put it in your source code, for example in the public folder.

Then, just set the path in the MESSENGER_DSN env variable like this XXX?cacert=/app/public/cacertfilename.cer

Excel COUNTIFS with wildcard on numeric data

Asked 2022-Jan-31 at 19:54

Can Excel COUNTIFS function use a wildcard to match numeric data? E.g. with the following contrived table:

I want to have a dropdown menu using Data Validation that allows the user to select 1, 2, 3, or * (wildcard). Then Excel should count the number of Ringtailed lemurs that equal the selected Age, where * will result in counting all the Ringtailed lemurs.

If the user selects 1, the output will be 2. If the user selects 2, the output will be 1. If the user selects 3, the output will be 0. And if the user selects *, the output will be 3.

This formula counts the number of Ringtailed lemurs when Age is 1

QUESTION

How do you use a random element from an array, remove that element from the array, and keep using random elements until the array is empty?

Asked 2022-Jan-12 at 01:03

This is my first stack overflow question, so if I am presenting something wrong, please let me know. I am pretty new to computer programming, so I just have a small webpage where I am just implementing things that I am learning.

I made a little quiz with random trivia multiple choice questions you can take if you press a button. I am using window prompts to ask the questions and get the answers, and I have all of the questions and answers stored as objects with question/prompt and answer pairs. All of those objects are stored in an array in a variable called shortQuizPrompts. I already have the quiz working and everything, aka., It tells you after every question if you got the answer to that question right or wrong, and it gives you a grade afterwards... I also have it set up so that if you enter an answer that is not "a", "b", "c", or "d", it lets you know that it isnt a valid answer. Those sorts of things.

As of right now, you can choose how many questions long you want the quiz to be out of the 24 total questions I have so far. It just asks the questions in the order that they are stored in the array. For example, you will never be asked the last question in the array if you do not choose for the quiz to be the full 24 questions long. However, I want to make the quiz ask the questions in a random order, while also removing those questions from the array as to not ask the same question multiple times.

I have tried increasing the iterator while looping through the array to a random number from 0 to the length of however many questions they chose. Then checking to see if the iterator was larger than the length of the number of questions they chose, it would decrease the iterator until it found a question that is still in the array that it could ask...

If anyone knows how to go about doing that, it would be great. Sorry for the long question btw. I am pretty new to coding, so this is probably a simple answer, but I digress. I'm pretty sure I did everything right. Thx.

You can shuffle the shortQuizPrompts array before starting the quiz. Array shuffle details can be found in this answer.

In your build directory, the *.exe file is already a "single exe file" that users can install. The other files such as the *.yml files are not important to the main exe file. You can simply ignore the rest or delete them and your build will work the same.

ANSWER

Answered 2021-Jul-18 at 06:11

There are two problems in your code -

In function ArrSwap() you are looping over index 0 to 5. So, when i becomes 5, Arr[i+1] points to Arr[6] which leads to read from a memory past your array bounds. Which is undefined behavior.
Secondly, if I get your requirement correctly, you want to swap the first and second elements swapped, then third and fourth and so on. So, your code has a logic error. In that case, in ArrSwap() the loop needs to increment by 2 instead of 1.

So the code may look like this after both issues are addressed -

You'll want to create a custom Gradle plugin.

As a sibling of all your project dirs, create a buildSrc directory, which itself will have a Gradle file (it needs to be built like everything else). Make gradle file under src, which will be your plugin. Put all of the shared gradle code (the dependencies block you posted) in that file. For example:

QUESTION

How to get the feature importance of ranklib generated random forests model?

Asked 2021-Feb-21 at 21:07

Using ranklib's learning to rank random forests generates an xml-like model. Ranklib has a tool that provides features' frequency which cannot necessarily be considered as feature importance.

How can I get the Gini feature importance or Gini index of random forests generated by ranklib? How to parse the tree generated?

Found in the Sourceforge discussion forum that you need to parse the model file yourself.

...

ANSWER

Answered 2021-Feb-19 at 04:47

I, personally, had a lot of struggles to get the Gini importance of features from a ranklib random forest and finally succeeded. Here I share the Github repository I made to solve the problem.

You can do it by running this command (use python3):

python Gini.py

Please see the repository for more details on how to do it.

The .assign method can handle equations, per https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.assign.html.

I'd suggest that the most flexible and pythonic way to do this would be to just have a list of any animals that receive the highlight tag. Then use a .apply and a lambda inside the assign. For example:

Heroku with Django, Celery and CloudAMPQ - timeout error

Asked 2020-Sep-23 at 12:58

I am building an online shop, following Chapter 7 in the book "Django 3 by Example." The book was written by Antonio Melé.

Everything works fine in my local machine. It also works well when I deploy it to Heroku.

However, when I try to use Celery and RabbitMQ (CloudAMQP, Little Lemur, on Heroku), the email message the worker was supposed to send to the customer is not sent. The task takes more then 30 seconds and then it crashes:

...

ANSWER

Answered 2020-Sep-12 at 22:23

So fairly familiar with heroku, though not your tech stack. So the general approach to deal with heroku timeout is this:

First, determine exactly what is causing the timeout. One or more things are taking a lot of time.

Now you have 3 main options.

Heroku Scheduler (or one of several other similar addons). Very useful if you can run a script of some sort via a terminal command, and 10 minutes/1 hour/24 hour checks to see if the script needs to be run is good enough for you. I typically find this to be the most straightforward solution, but it's not always an acceptable one. Depending on what you are emailing, an email being delayed 5-15 minutes might be acceptable.
Background process worker. Looks like this is what you are trying to do with Celery, but it's not configured right, probably can't help much on that.
Optimize. The reason heroku sets a 30 second timeout is because generally speaking there really isn't a good reason for a user to wait 30 seconds for a response. I'm scratching my head as to why sending an email would take more than 30 seconds, unless you need to send a few hundred of them or the email is very, very large. Alternatively, you might be doing a lot of work before you send the email, though that raises the question fo why not do that work seperately from the send email command. I suspect you should probably look into the why of this before you try to get a background process worker setup.
