theming – How do I test for an empty Address webform element?

Using Drupal 9.1.3 : Webform 6.0.0

I have 4 composite address elements in a webform that may or may not be filled, depending on the user’s other selections within the form.

I can use the default email Body format, selecting the checkbox: Exclude empty elements, but this outputs a list of the Element Title, followed by the Element data.

I would like to display the output using twig markup, with a custom title on the left and the element data on the right as below:

Title Data
Address 123 The Street
The Town
County, Post Code

Using the webforms debug submission when testing the form it displays the address: element as null when the form is submitted without any data in the address element of the form.

I have used the code below to check for the null attribute.

{% if webform_token('(webform_submission:values:address)', webform_submission, (), options) == '' %}
  <div>Address Element is EMPTY using the '' test</div>
{% elseif webform_token('(webform_submission:values:address)', webform_submission, (), options) == null %}
  <div>Address Element is EMPTY using the null test</div>
{% else %}
  <div>Address Element is EMPTY</div>
{% endif %}

This always displays ‘Address Element is EMPTY’

If I test other Webform elements that results in a empty string eg. ” when no data is entered, the above twig code works with the correct (webform_submission:values:element) and I can elimate the empty custom Title and element using twig code.

How are p2sh address spent

So, I was looking into how P2SH transactions are working and by looking at different blog post and in particular to this answer, I have the following question.

So, let’s take the same transaction:

enter image description here

What I am not getting is how the operation are done.

  • Is the scriptSig executed first?
  • What is checked to be equal to 0b49fe...df1? How is it calculated ?

networking – How to use a web proxy Python program to hide IP address while web browsing?

I’m new to learning creating web proxies using Python. I do not really understand the concept of the Python program and how it is used to hide my IP address while accessing websites. Most Youtube tutorials and programming websites use a similar program as the example shown below, note that the ‘exampleproxyaddress’ must be taken from a free proxy website and not all proxies work.

from urllib import request as urlrequest
PROXY_ADDRESS = 'exampleproxyaddress'
url = 'http://icanhazip.com'
request = urlrequest.Request(url)
request.set_proxy(PROXY_ADDRESS, 'http')
response = urlrequest.urlopen(request)
print(response.read().decode('utf8'))

My understanding and expectations were different, I thought that after running the code, when I open the ‘http://icanhazip.com’ website using my web browser, my public IP would change to the proxy IP that I had entered in the code, but the IP shown was still my original public IP. Instead, I would only get a 200 response from the terminal returning my proxy IP address. The Youtube videos and websites did not explain or demonstrate well on how to use the code and its practicality.

I know the code is working fine and as intended but how can I use it for web browsing? For example, after running the program, I access the http://icanhazip.com website and it would show my proxy IP that I had entered earlier. Or am I completely misunderstanding the concept of web proxies?

Any advice would be greatly appreciated, thank you!

When a user completes the form to attend a conference. I ask for another email address so their supervisor knows they have signed up and for what date.

How can I use the field on the form as the address to cc the Email to.
the field is “Supervisors Email address”

I would like it to send as soon as they submit the form.

How to display the full email address in Gmail folder view (local-part and domain)?

An e-mail address consists of a local part and a domain name, e.g. info@example.com where info is the local-part and example.com is the domain name including the top level domain.

When I open a folder in Google’s Gmail (e.g. Sent) I can see the emails that I sent to other people and organizations.

Screenshot of Gmail not showing the domain names

As you can see in the screenshot I have to send many emails to email adresses that are similar to info@company1.com, info@company2.com, support@company3.com, etc. However Gmail always only shows me the local part of each email (info, support), but never shows the domain name (company1.com, company2.com).

This behavior is very annoying because I cannot see the domain name in the folder view, making it very difficult for me to quickly find specific emails which I would recognize by their domain name.

How can I configure Gmail so that not only the local part is shown in folder view but also the domain?

domain name system – Can the IP address of a root nameserver change?

Quotation from the IANA page on root servers:

Operators who manage a DNS recursive resolver typically need to
configure a “root hints file”. This file contains the names and IP
addresses of the root servers, so the software can bootstrap the DNS
resolution process. For many pieces of software, this list comes built
into the software
.

(my emphasis)

Therefore, if root servers’ IP addresses changed, software everywhere in the world would have to change, too. To me, this is enough evidence to conclude that these addresses will never change.

EDIT: The first IP address is hardwired into RFC1400. From the RFC:

After the transition, the host.txt file will be available only from
nic.ddn.mil and hosts.txt will include ONLY MILNET HOSTS. On April
1, 1993, a new root DNS server will be placed in service. It will be
available at ns.internic.net ( 198.41.0.4 ).

This indicates that this address will not change as long as this RFC is in effect, but in theory, addresses of other root servers could change. I guess that DNS software should be designed so that it updates the root hints file from ns.internic.net.
