When I invite a co-worker to meet with me, I often want to meet via a Slack call. It is easy to add a link to the calendar invite for a Zoom call, a Hangouts call, or even a Jitsi call (we use Google Calendar and there are integrations for all three). I am wondering if there is some way to achieve the same convenient “hop on the call in one click” when using Slack.

On a fresh Ubuntu 20.04 installation, I installed Unity and lightdm. The login screen looks different, where we now have the option to select the desktop environment to use before logging in.
sudo apt install ubuntu-unity-desktop
I then decided to switch back to the default GNOME desktop by uninstalling Unity. However, the login screen does not go back to the original one that came with the fresh Ubuntu 20.04 installation even after restarting the computer.
sudo apt purge unity-session unity
sudo apt autoremove
sudo apt install ubuntu-session gdm3
How can we restore the original login screen in Ubuntu 20.04?

I’ve set different password for 'root'@'localhost' and 'root'@'127.0.01' like this:
mysql -u root
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('pswd1');
SET PASSWORD FOR 'root'@'127.0.0.1' = PASSWORD('pswd2');
but when I try to login like this:
mysql -u root -p -h 127.0.0.1
I still have to use the first password pswd1 even though according to this:
another password pswd2 was set for 127.0.0.1.
What is the problem here? How can I set 3 different passwords for ‘root’@’localhost’, ‘root’@’127.0.0.1’ and ‘root’@’::1′ and login to those accounts with those passwords?

I’m fairly new to Docker so excuse any obvious ignorance or misunderstandings. That said, I’ve been coding and configuring web applications for a long time now. I have recently been dabbling with some more sophisticated (Docker and “traditional”) web/application server setups and experimenting with performance enhancements and simplifying deployments.
My personal favorite configuration to use for most projects thus far is nginx as a (mostly) “static file” web server &&|| caching mechanism &&|| Load Balancer in a reverse proxy config with Apache v2.4+ as the “backend” which runs PHP (also Perl &&|| Python) in a “FastCGI” (PHP-FPM) configuration (with mod_php disabled) and mpm_events (instead of mpm_prefork). We can always add in something else also such as REDIS or memcached, where applicable (but I rarely see a significant performance gain when using Cloudflare caching).
I’ve been dabbling with a few different ways to keep my “favorite web server composition” flexible and “ephemeral” enough to accommodate any and all possible options for further performance gain or resource load management. What I keep seeing is that there seems to have been a shift towards using PHP-FPM in its own separate “stand-alone” Docker container sometimes around late 2019.
Why?
While I can appreciate keeping resources isolated and separate for an easier to debug/config/secure configuration(s), I don’t fully understand what the benefits are to having PHP-FPM in a separate Docker container that is implicitly REQUIRED by the application that the Docker containers are comprising.
If anything, having a separate PHP-FPM container seems like additional configuration, additional resource consumption and an even more complicated build/deploy consideration in a CI/CD pipeline.
I can even get onboard with “simple preference”, such as instead of using Apache2 and nginx on the same Ubuntu/Debian or RHEL/CentOS container, break off nginx into its own container(s) and simply config your hostname(s) &&|| IPs and ports appropriately.
But what is a practical use case and advantages for having PHP-FPM separated from Apache or nginx containers for any additional benefit beyond perhaps using more Dockerfile &&|| docker-compose.yaml and less ba.sh scripting to get the same job done? If any part of the application fails or falters, then functionality will suffer. The additional network &&|| docker-network communications and hostname resolutions seems like it would just be a performance penalty over combining certain aspects of the docker-composer-ed application together, rather than splitting them up simply for the sake of splitting them up.

I would like to limit my docker volumes in size, So I don’t have one container crashing my entire environment because of excessive writes depleting my storage space.
I found it is possible to limit volumes size at creation time using --opt o=size=100m
However Is it possible to change the size limit after I have created the volume?

Currently I have a site with around 6.000 articles running on a custom built cms platform, but due to demand from the client, we have been tasked to convert all data to WordPress. Everything is stored in MongoDB in a custom structure (nothing extraordinary) and I have been looking at how I could convert the data to match the XML structure of WordPress for easy import, though not sure if I have to build such conversion script myself, or if an open source data-pairing tool exists, where I can match a MongoDB query and its data to the designated fields in a WordPress DB.
The article contents have been structured using EditorJS which acts a lot in the same way as the Gutenberg editor in WordPress, though I would need to know, how I should convert the data to match the Gutenberg editor, or if I should simply render the data as HTML and save it as such in the XML for import?
Categories are stored in a separate collection with a parent -< child structure, and pages pretty much acts as normal html.
Q: How would one go about converting this to WordPress data?

My computer has two systems, Windows 10 and ubuntu18.04. Today, when I tried to get into Ubuntu(I already laid it aside for about one week ), the whole screen showed pure purple for at least 10 minutes, so I forced the computer to shut down.Then when I tried to get into Ubuntu again, it showed :

Then I tried to open ubuntu in recovery mode,but the outcome was same.And I also tried this solution:https://forums.linuxmint.com/viewtopic.php?t=47594,doesn’t work either.
At last I run fsck.ext4 -y /dev/sda1(where the root is),and showed:

Anyone know how to deal with is issue?Any help would be appreciated!

I have a pandas DataFrame that looks a bit like this:
id name date col1 col2 total
0 123456748 EXAMPLENAME 2020-09-01 SOMEDATA MOREDATA 5.99
1 123456748 EXAMPLENAME 2020-09-01 SOMEDATA OTHERDATA 25.99
There are 15 columns, the name values are associated with the ID, and the rest is some data relevant for that person. col2 would have about 400 unique values. The database would be about 300,000,000 rows to start with, and then will grow at about 500,000 records per week.
The records in the database will never be updated or deleted, only new ones will be added. Final purpose of the database is to have a web app in which the user can select the ID of the person. The database would retrieve the information, and the website would render a graph and a dataframe. The expected traffic of the website is very low, so I was thinking about using SQLite.
Based on that, I have two questions:
Thanks.

I have developed my DRF back-end API locally, deployed it on an AWS Lightsail instance (with a public static IP) and I now want to secure it with HTTPS.
I understand that in order to use Let’s Encrypt (and not pay for an SSL certificate), I have to have a domain name associated to my instance IP since Let’s Encrypt doesn’t provide certificates for public IPs. As this is my back-end API (and not just a website), I don’t intend to buy a domain specifically for this.
Can I, somehow, associate my Lightsail IP with another domain that I’ve already purchased (and is used to host my company’s landing page)? If yes, will there be any impact on my API’s performance?
Is there any other alternative to obtain an SSL? (Apart from paying another CA to issue this for my public IP?)

I am unsuccessfully trying to setup multisite with WordPress’s fresh setup(WordPress installed in subfolder under htdocs of Localhost), but existing copy of Database already imported(provided by client).
Now the database already has atleast 15-16 different domain URLs already as entries of siteurl and home field in various wp_options tables for each site-domain.
And I want to use the same site-domains with little modifications to be able to work in Localhost WP multisite(like .com replaced with .local or so).
But even after doing all that and setting up multisite with following wp-config.php settings, when I try to access domain1.local, it tries to redirect to domain2.local like http://domain2.local/wp_signup.php?domain1.local and never redirects properly:
....
/* Multisite */
define('MULTISITE', true);
define('WP_ALLOW_MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', 'domain1.local');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);
....
.htaccess:
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]

I work for this Accounting company – as a Product Owner – that uses several external services (one for Contract management, another one for Accounting Demands management, a third one for Financial purposes and so on).
My IT Director wants us to build an Event-Driven Architecture to gather all the events that happen externally and bring them into our NoSQL in as-close-as-possible realtime.
The problem specifically is: how can I gather this data from external sources? What would be the best procedure for hundreds of events every day from different services? Consuming their APIs periodically?
Can you guys shine a light on how this can be properly done?
