QUESTION
I am trying to set-up automatic backup for postgres db on a local headless server on Debian. I have a script:
...ANSWER
Answered 2020-Nov-13 at 23:48In the absence of a user map via pg_ident.conf, only a linux user named "db_user" is allowed to log in as the database user "db_user". That is what peer authentication means. Your .pgpass doesn't matter, as peer authentication doesn't use passwords.
The one line from pg_hba you show also doesn't matter, because "postgres" != "db_user" so that line doesn't match. But clearly you have other lines as well which you haven't shown us. If you look in the server's log file you should find more details about the error, and which line of pg_hba was used.
There are lots of solutions. You could change your linux username to match the postgres username, or change the postgres username to match the linux username, or use pg_ident.conf to map between them, or change your pg_hba (the correct line of it!) to use md5 rather than peer.

I'm creating an android app for a class project and this is my first time writing any android code. Basically I have a main activity and a preference activity. I added a menu where users can access the settings and to test I set up a toast message to display when settings is clicked. I started to implement the settings activity after watching a few videos and reading a few articles, but now when I click on settings the app crashes and I can't figure out why. Please help me.

...ANSWER
Answered 2020-May-13 at 05:24GitHub itself, through its GFM (GitHub Flavored Markdown Spec) does not support Katex
You would need for your GitHub repositories to be a GitHub Pages project in order to include for instance a Jekyll plugin like linjer/jekyll-katex, in order for those pages to represent a Katex section properly.

I'm converting multilingual strings to html. I have to use html entities using their keyword representation not decimal or hex. I currently use following implementation I just wonder if ASP.NET does have a on-board library which I can use.
...ANSWER
Answered 2019-Sep-20 at 10:24It looks like there is a way, using the AntiXSS library which was announced to be End of life (except for security fixes if needed).
So it isn't deprecated or obsolete, just no longer very actively maintained because parts that Microsoft considered essential have been ported into .NET Framework v4.0. And it looks they did not port the part that we need here.
Steps to take:
(1) Through NuGet package manager, add AntiXSS to your project.
(2) Write your code like this:
QUESTION
I'm trying to deploy a cloud function for my react native app that sends a notification to users when a new node appears in the database. To do so, I'm using Expo's Push API as shown here: https://docs.expo.io/versions/v32.0.0/guides/push-notifications and following a tutorial available here: https://www.youtube.com/watch?v=R2D6J10fhA4
I've been able to acquire device tokens and save them to my database just fine. However, I'm unable to deploy the function to my database because of an error that says:
31:27 Parsing error: Unexpected token, expected ,
It's throwing a fatal error at the line 'body: JSON.stringify(messages)' as if it expects a comma right after 'stringify'. I'm very unsure of how to proceed from here and can't seem to find any posts tackling this specific issue.
Any help and/or advice is appreciated! Thank you.

QUESTION
I am currently doing some responsive work on a new Wordpress site I am building. It is a custom theme built on Underscores and so I have included the bootstrap files for use on the navbar and grid columns. All the bootstrap functions are working correctly, only when my navbar drops down into tablet view (with the menu items hidden and the toggle button showing), when the page is loaded, the navbar loads opened and then when the toggle button is clicked, it slides up and immediately reopens again.
The classes applied to the navbar when the page loads are:
...ANSWER
Answered 2018-Apr-26 at 17:10Solved! The problem was that I had a Page Builder plugin installed that called in Bootstrap 3. I completely missed this in the source and so I had Bootstrap 3 & 4 fighting over control for the navbar.
Note to self: Always check for duplicate bootstrap includes if using plugins.

I'm having a hard time figuring out how to get the position(column and row) and the content in the QLineEdit. I'm using a eventFilter to get the signal but from there i'm stuck. any advice? Thank you
...ANSWER
Answered 2018-Mar-18 at 23:50As you indicate in your comments, you only want to obtain the text when an element that is set in the QCompleter is selected, for this we must use the void QCompleter::activated(const QString & text) signal.
To do this, a slot is created and the connection is made:
