QUESTION
I have a really specific and tricky bug that I can't figure out how to fix/work around and I can't find a similar case on here.
I have a bash script that invokes a Julia script partway through to generate animation frames, then calls ffmpeg to render the animation. When I run from the terminal everything works great. I wanted to automate the process so I got a fun random simulation once a day, so I added it to my crontab and it runs--but only to a certain point. The animation always stops at a specific frame, then the rest of the script continues and spits out the chopped off animation.
I thought maybe cron was the problem, so I installed jobber and ran the job from there--with jobber the script just stalls at the Julia part. From the resource manager I can see the Julia process still using memory (although well beneath the limit) but it's just gone to sleep.
Another strange thing that I have noticed is that when I invoke the script manually from the command line it runs ~2-4x faster in generating the animation frames than when its running automatically via crontab/jobber.
Is this a weird resource issue? To get the longer animations to render initially I had to modify my ulimit settings, but I changed the config file so they should be set higher for everything? How can I debug this further and/or rectify it?
If you want to see an example of the code being run (both the shell script and julia script being invoked) it's pretty much up to date on my github here. In the threeBodyProb.jl file the I'm pretty sure the hang up is with the frame function in the for looop at the end of the file.
I am running Linux Mint 19.1 Cinnamon. Thanks in advance for the help!
Here is the part of the bash script where it hangs up:

Ultimately it appears the problem was not with cron or the bash script, but instead with Julia's GR backend. I added the line
QUESTION
So I've seen a lot of tutorials here explaining what to do, but no matter what I change the static files won't seem to load. This is what my files are looking like atm
settings.py
...ANSWER
Answered 2019-Oct-30 at 18:39Below configs worked for me. Django only needs two things.
- What should be the base static URL (STATIC_URL)
- And where to search static files (STATICFILES_DIRS)
Remove static urlpatterns
from urls.py. Only define STATIC_URL
and STATICFILES_DIRS
in settings.py and remove STATIC_ROOT

QUESTION
I have a database structure like this: Firebasedatabase I want to get the boolean value to fill another checkbox in my listview items. When I add a new item, I use a checkbox to set the boolean value to "true or false" in firebase. But I want to get the value to fill another checkbox in my listview. Here is my adapter (It's inside my MainActivity)
...ANSWER
Answered 2018-Dec-03 at 19:10Your solution lies with the valueEventListener()
available in Firebase Database for getting realtime updates from database.
You need to add the valueEventListener()
in the list item which you want to modify based on the boolean value in the database.
You need to modify the onDataChanged()
callback function in the valueEventListener()
which gets automatically called upon changes in the database at the particular DataReference
on which it is called.
valueEventListener()
gets automatically triggered when the corresponding value (i.e. database reference where it points) in the database changes, after the function is triggered you execute the desired code to set the checkbox as checked by calling function setChecked()
.
It may look like this checkboxVariable.setChecked(true)
You may read more about valueEventListener()
which is function available over the class DatabaseReference
.
Example from documentation on valueEventListener
Hope this helps.
QUESTION
I've got 2 activities that stores/get data from firebase, different data but they are related to each other.
The first activity stores for example different food dishes in a listview, and when I click on one of the items I get to the second activity where I can store different things under the first item i chose in my first activity. So for example, if I click on "PIZZA" I get to a new activity where I can store "Italian Pizza". And this is working fine. But I want to have a middle activity that will appear after my first activity, and in this middle activity I want to have a button that gets me to my second activity.
So between the first and second activity it is no problem, works like a charm. But when I try to use this middle activity with a button, it doesn't work. I guess it has to have something to do with the middle activity, that it is not "connected" with the database for the other activities. But I don't know, need help :)
I get this error when trying to click on the add button:

QUESTION
ANSWER
Answered 2018-Jul-12 at 16:23The query is returning the second row of the p_sale_inv
table, joined to two rows of the p_sale_part
table. That is why the dates are the same: they are from the same row of the table.
(Note that only one p_sale_inv
row has a date that matches the WHERE clause. So you wouldn't expect both rows of that table to be returned.)
Edit: Maybe this will help clear up the misunderstanding. Here is the same query with the INNER JOIN's removed:

Answered 2018-Apr-25 at 17:11I would advice you to build your query dynamically depending on the available input. This reduces your code and makes sure you will not have to add new code in multiple places should you extend your search in future.
