First go into the database;
use dbname;
Then to alter it's type;
alter table tablename modify column columname type;
This doesn't fuck up the data unless the new type isn't compatible with the old one. Also make sure to make a backup before hand.

The fuck's userful. Huh??
from objects to arrays. this thing generates data to fit your bill
to add a new font put it in /usr/share/fonts/

Replace that damn thing with a random variable for all I care. Just replace it. Can't believe, I'm being this aggressive towards myself.
systemd group new command
create new group in #groups
by default the port is set to 2369 but in truth it's 2368
First create A records from both the domain's root and www subdomain towards the server. Then create the usual nginx conf. But under that conf add this block also
server {
server_name www.example.com;
return 301 $scheme://example.com$request_uri;
}
In the general tab add a section for chmod and chown commands when popping up a new site.
This is great for logging. You get a clear picture as to what went wrong where.
The outer layer - Nginx
The middle layer - gunicorn/WSGI
The inner layer - app script

This should probably tell mkdocs to auto generate the pages instead of having to specifying all of them. Also check out docs_dir config option
The switching active version shouldn't be a whole header. It should be under version mayhem.
Then there's some grammatical errors in the plugins section

def batch_mailing():
req = requests.post(
"https://api.{eu}.mailgun.net/v3/{domain}/messages",

"from": "{from display name}",
"to": "{mailing list name}",
"subject": " {mail subject}",
"template": "{domain template name}"
)
return req
response = batch_mailing()
print(response.text)
get rid of the eu if the domain is based on another country
after running the script you need to install python-certbot-nginx
Then generate the certificates.
After which restart the service
You must also install green light seperately. Check if you can do that with the script with an optional thing
Also, to disable sign up in greenlight check this site

There are two causes for this.
For web server limitations
###Apache.
Incease the LimitRequestBody
It can be used in any virtualhost or location directive. Check here for more info. Here you need to convert whatever rerquest size you need into bytes. Use this to convert
<Directory "/var/www/site">
LimitRequestBody 5242880
</Directory>
Then remeber to restart apache using
sudo service apache2 reload
This is easy. Just edit
sudo nano /etc/nginx/nginx.conf
Then change this to whatever size you want
client_max_body_size 2M;
Again remember to reload nginx using
sudo service nginx reload
FIrst find what php config file your running. Now the thing to remember here is if your running both apache and nginx at the same time. There's a possibility that the two are using different php.ini's so you'll need to change both of them.
First create a php-test file at /var/www/php-test. Find how here <-- link to php page with a test file example
To find which config apache is reading from. Create a new conf file at /etc/apache2/sites-available and point it towards the php-test folder at /var/www
Remember if your using nginx to route apache traffic. You'll need to customize the apache config in /etc/nginx as well, with the domain you put in side of the apache config file.
To find which is read in nginx create a config file at /etc/nginx with the usual php config. Then point it towards the php-test folder.
The config file that's read by php should be plain obvious in the info page. So now to edit the config file
In the .ini file's there two need to be changed
upload_max_filesize = 100M
post_max_size = 100M
change them to whatever size you see if. Again restart the services handling php
sudo service apache2 restart
sudo service nginx restart
sudo service phpx.x-fpm restart
That's it. This should most probably solve the issue

change the chmod to 774
With the following rules-set, NTP-synchronization is working perfectly for me:
sudo ufw allow 123/udp
sudo ufw allow out 123/udp
sudo ufw allow out 53
I've allowed UDP port 123 for both incoming and outgoing traffic to NTP work. Additionally I also needed to open TCP port 53 (DNS) for outgoing traffic since /etc/ntp.conf contains domain names of NTP servers. .

Two types of backups
Physical
This is basically copying the base sql dir after stopping sql.
Logical
mysqldump --all-databases > /backup/mariadb.dump
mysqldump dbname > /backup/inventory.dump
first create the database in mysql then import the tables and data
mysql dbname < /backup/mariadb.dump
This is causing a page error in mobile view.
If there's a page that's a bit long. If your scrolling down, at a point the top bar automatically retracts. At that moment you can zoom the page out. The already existing layout stays the same but on the right there's an infinite void you can scroll to horizontally.
But guess what. If you just scroll up a bit. Over an unknown but stationary cutoff point, the top bar comes down again. When this happens the void suddenly disappears and the site is good as new.
