amazon rds – Can we take pg_dump from Aurora PostgreSQL read replica?

I wondering to know Can we take pg_dump from Aurora PostgreSQL readonly replica?

what are the possibilities on it, I don’t want to bother writer replica.

I want to take daily DB backup and its has around 200GB size.

My use case to restore schema or tables as if required. With snapshots I had to restores entire cluster and copy of them which is not suitable for use case.

Read environment tags from other dockers in docker compose

I want to know if it can be done and if so, how to do it, to be able to read the environment tags.

I leave an example of what I have seen and I am not able to find information with which to understand how it does it (docker compose):

version: '3'

services:
  nginx-proxy:
    image: budry/jwilder-nginx-proxy-arm:0.6.0
    restart: always
    ports:
      - "80:80"
      - "443:443"

  letsencrypt:
    image: jrcs/letsencrypt-nginx-proxy-companion:stable
    restart: always

  nginx:
    image: tobi312/php:7.4-fpm-nginx-alpine-arm
    restart: always
    expose:
      - "80"
    environment:
      - VIRTUAL_HOST=example.host.com
      - LETSENCRYPT_HOST=example.host.com
      - LETSENCRYPT_EMAIL=example@mail.com

In this example you can see that the dockers nginx-proxy and letsencrypt are able to read the tags VIRTUAL_HOST, LETSENCRYPT_HOST and LETSENCRYPT_EMAIL. My question is, how do they do that and how can I do it? I would like to use this in a dockerFile, but I expect anything

Thanks in advance for any help

c++ – API for input stream with read until

I want to create a stream class The input stream should read/parse a continuous range from left to right providing convenience methods. The implementation isn’t a problem but choosing a consistence API.

A basic example would be:

input_stream is("Hello! 42");

is.peak(); // 'H'
is.read_n(7); // "Hello! "
is.read<int>(); // 42

I also want to support an operation known as read until to read the input stream until a specific string occurs. On first glance, this doesn’t sound very problematic but if you take a closer look there are 3 possible outcomes:

input_stream is("Hello! 42");

is.read_until("!"); // ?
  1. function returns “Hello!”, input stream points to ” 42″
  2. function returns “Hello”, input stream points to ” 42″
  3. function returns “Hello”, input stream points to “! 42”

My idea is to support all 3 variants with 3 different functions which should be unambiguous to the reader but it is really hard to explain what actually happen. Here are my ideas:

• read_until_include(cmp) – process the cmp and returns the part before + cmp

• read_until_exclude(cmp) – process the cmp but returns only the part before

• read_up_to(cmp) – does not process the cmp and
returns only the part before (leaves the cmp in the input stream)

I am not a big fan of my own idea. Could anyone please give me an advice where to go from here?

formulas – Google sheets – how can I use functions to resort my table in a way charts can read it well

I’m using app sheets to see what I do in a day. I select the task I am starting on the app and app sheets dumps the data into a table in google sheets.

I have made an example of what this looks like. Sheet1 is what it looks like At the moment and sheet2 is what I would like it to look like (or something else that will help charts read it).

https://docs.google.com/spreadsheets/d/1GF6cjlNMSTJov4G6ZMusXSWS-DMwnK4SgQqNs8d8uws/edit?usp=sharing

I have been pulling my hair out trying to do this so if you know how please tell me.

Updated sitemap not read automatically by Google

Google is not reading my sitemap of my wordpress site automatically. The ‘last date read’ remains the same as the submitted date. I had updated the contents of my site a couple of weeks ago, and the contents of sitemap were also updated automatically. But the updated sitemap was not read automatically by Google thereafter. I waited for a week but it remained the same. Finally, I was forced to resubmit the sitemap and google now discovered by new URLS immediately.

Is this normal? Does google take weeks to read sitemaps? Or is this some problem from my website side?

custom roms – System partition locked to read only in Android 10

Help, I don’t know what I did but after installing a custom ROM, I noticed that my system partition cannot be mounted as read/write.

I tried


“mount -o rw,remount /system” command on a terminal emulator, ADB shell, and TWRP terminal

The command shows no feedback showing failure (maybe I succeeded?)


Mount it using the built-in TWRP mount function.

The system check box can be checked out (it doesn’t retain its check mark on reboot)


Some apps that actually works according to sources and reviews.

Some say (Failure to mount..) Some say (System mounted as rw) some doesn’t have feedback.


I don’t know what to do.

I noticed this when I installed a custom ROM. I tried using another custom ROM but same thing. Also reformatting doesn’t help. I don’t know if this occur on the stock ROM.


For reference

Device: Xiaomi Mi A2

Android version: Android 10

Custom ROM: AICP nightly build 15.0

sharepoint online – Can’t create alerts for document Library for which users can only read their own documents

It’s the default behavior that user cannot create alert when we set read access on their own items.

As a workaround, you can create a custom workflow to use “send email” action and start workflow automatically when the item changed in SharePoint Designer.

Here is a similar post for your reference.

networking – On Windows 10, can programs read saved wifi passwords behind my back?

I don’t see any settings for giving or denying access to saved wifi passwords. I know if the user goes into network properties, wifi passwords are viewable as plain text from there, but this is different from a third-party program reading wifi passwords without the user’s knowledge or consent.
Does windows allow programs that are not part of the system to read saved wifi passwords without the user’s knowledge or permission?

sharepoint online – SPFx WebPart started giving TypeError: Cannot read property ‘Content’ of undefined

This webpart was working on a classic Publishing site. Recently, it started throwing this error message:

Error details: Error: Error initializing application. Error: TypeError: Cannot read property ‘Content’ of undefined

When I place this webpart on a modern page, it works without problems but I do not have the luxury to serve it on a modern page. Another strange thing is that it has to be on the rootweb. It does not work under sub webs anymore.(I am thinking something has changed on microsoft recently…)

I can not even debug it because it works in the local workbench and hosted workbench.

Any ideas on how to solve this? or troubleshooting tips?
