Time Complexity ⏱️

Time complexity is one of those Computer Science concepts that's scary in its purest form, but often fairly practical as a rough "am I doing this right" measurement.

In the words of Ned Batchelder, time complexity is all about "how your code slows as your data grows".

Time complexity is usually discussed in terms of "Big O" notation. This is basically a way to discuss the order of magnitude for a given operation while ignoring the exact number of computations it needs. In "Big O" land, we don't care if something is twice as slow, but we do care whether it's n times slower where n is the length of our list/set/slice/etc.

Here's a graph of the common time complexity curves:

Remember that these lines are simply about orders of magnitude. If an operation is on the order of n, that means 100 times more data will slow things down about 100 times. If an operation is on the order of n² (that's n*n), that means 100 times more data will slow things down 100*100 times.

I usually think about those curves in terms of what would happen if we suddenly had 1,000 times more data to work with:

• O(1): no change in time (constant time!)
• O(log n): ~10 times slow down
• O(n): 1,000 times slow down
• O(n log n): 10,000 times slow down
• O(n²): 1,000,000 times slow down! 😲

With that very quick recap behind us, let's take a look at the relative speeds of all common operations on each of Python's data structures.

In your Python journey, you’ll come across situations where you need to signal that something is going wrong in your code. For example, maybe a file doesn’t exist, a network or database connection fails, or your code gets invalid input. A common approach to tackle these issues is to raise an exception, notifying the user that an error has occurred. That’s what Python’s raise statement is for.

Learning about the raise statement allows you to effectively handle errors and exceptional situations in your code. This way, you’ll develop more robust programs and higher-quality code.

In this video course, you’ll learn how to:

• Raise exceptions in Python using the raise statement
• Decide which exceptions to raise and when to raise them in your code
• Explore common use cases for raising exceptions in Python
• Apply best practices for raising exceptions in your Python code

The TalkingDrupal podcast had Alexey Korepov on to talk about Test Driven Development. Alexey has written the Test Helpers module, a development package that provides many useful utility tools for writing unit tests for your Drupal code.

When it comes to Drupal development, GitHub Actions offers invaluable assistance in automating repetitive tasks, standardizing your processes, and enhancing code quality. By defining workflows as code in YAML files that can react to various events, it provides flexible customization and scalability. Pre-built actions can handle common tasks like building and testing code, while custom actions can be tailored to project-specific requirements. Let's explore some of the best practices along with examples of actions you could use in your next Drupal project.

Do you know what custom GPTs are? They're configurable and shareable chat experiences with a name, logo, custom instructions, conversation starters, access to OpenAI tools, and custom API actions.

For protecting the privacy of our users and the security and integrity of their systems, usage of transport encryption and authentication is crucial for any network communication. HTTP over TLS (HTTPS) is probably the most widespread set of protocols for that. What do we need to look out for when using this in our applications?

If you want to offer your users a hassle-free login experience, convenience and security, Single Sign-On (SSO) is the way to go. SSO is an authentication process that allows users to access multiple applications or services with a single set of login credentials. Auth0 is an identity-as-a-service (IDaaS) platform that provides authentication and authorization services for applications and APIs. It offers a comprehensive set of features for implementing secure and customizable authentication solutions, including support for various authentication methods such as username/password, social logins, and multi-factor authentication (MFA). In this article, you will learn more about SSO and Auth0 and how you can integrate it with your Drupal website. Benefits of SSO Integration in Drupal Seamless User Experience: Integrating SSO into Drupal enables users to log in once and access all connected applications seamlessly, eliminating the need for multiple logins and enhancing user convenience. Centralized User Management: SSO centralizes user authentication and authorization, making it easier for administrators to manage user accounts, permissions, and access control policies across multiple Drupal sites or integrated applications. Enhanced Security: SSO enhances security by enforcing consistent authentication policies and enabling centralized management of user access, reducing the risk of security breaches due to weak passwords or unauthorized access. Reduced Development Efforts: By leveraging Auth0's SSO capabilities, developers can significantly reduce the time and effort required to implement authentication and authorization features in Drupal applications, accelerating the development process and time-to-market for new features and functionalities. Take a look at this article where we discussed integration of SSO with Drupal using SAML Steps to Integrate Auth0 SSO in Drupal Prerequisites Auth0 account SAML SP 2.0 Single Sign On (SSO) - SAML Service Provider  Auth0 configuration Register to Auth0. Go to https://manage.auth0.com/ and log in. Create the tenant. To create a tenant, click on the drop-down near the logo in the top left corner. You will see a pop-up fill the required information in that pop-up like tenant name, region, and environment. Click on the Create button. Next, click on the "Applications" option in the left menu. A list will open. Then click on “Applications” on that list and you will see an application page. Click on the “Create Application” button. You will see a pop-up, enter the application name in that pop-up and select “Regular Web Application” then click on Create. Next, click on that application and go to the settings tab. In the Settings tab, you can update the application logo if you want.  In the Settings tab, add the callback URL "[Domain]/samlassertion" to the "Allowed Callback URLs" field and then click Save. Then go to the “Addons Tab”. In the Addons tab, click on the "SAML2 Web App" option. You will see a pop-up with two (Settings and Usage) tabs. In the Settings tab, add the callback URL "[Domain]/samlassertion" and click the Enable button. After this go to the Usage tab. In the Usage tab, click on the "Download" button of "Identity Provider Metadata". Drupal application configuration Install the "SAML SP 2.0 Single Sign On (SSO) - SAML Service Provider" contrib module “https://www.drupal.org/project/miniorange_saml” in your Drupal application using composer.composer require 'drupal/miniorange_saml:^3.0' Go to the Drupal website and log in as administrator. Go to "Configuration" and then click on "MiniOrange SAML Login Configuration". Go to the “Service Provider Setup” tab Click "Add New IDP". Upload the metadata file that we downloaded from Auth0. Click on the save button. Steps to add role mapping Go to “Configuration” then click on "miniOrange SAML Login Configuration". Go to the “MAPPING” tab Click on the “Enable Role Mapping” option (If not enabled already). Select the “Library” role from the dropdown. Click on the “Save Configuration”. Then clear the cache and visit the login page.You will see an SSO login link above the submit button. Click on that link. You will be redirected to the auth0 login page If you have an Auth0 account then enter the username and password otherwise you can create an account using the signup link. After login you will be redirected to your Drupal application and your account will be logged in. Final thoughts The demand for seamless user experiences and robust security measures continues to escalate by the day. By integrating Auth0's Single Sign-On solution with your Drupal site, you're not just staying ahead of the curve — you're shaping the future of online interaction. But the journey doesn't end with integration. The next step is optimization. Continuously refine your authentication workflows, leverage Auth0's advanced features to customize user experiences, and stay vigilant against emerging threats. Reach out to our Drupal development team to enhance your user experience with features like these.

Targeting Android as a platform is attractive for our applications, both as a intermediate proving ground for Plasma Mobile, and due to the large market share. For new Kirigami-based applications that is a fairly straightforward process thanks to the portability of Qt. There is however also lots of valuable code predating mobile UI considerations, and functional gaps in Qt, which is where KDE Frameworks can help. What do we have already, what still needs to be done, and how can we do it?

Currently, we are observing an incredible development in technologies, especially in Artificial Intelligence field. Indeed, by learning from massive data, AI is particularly good at some tasks that normal algorithms cannot achieve as good level of performance, such as: image classification, speech recognition, object detection, tendency prediction, feature extraction, etc. Moreover, new AI algorithms with the emergence of neural networks and deep learning even makes AI models more robust, so that they can now give better prediction without any limitation in improving themselves.

Being aware of those assets, digiKam team has considered using deep learning in digiKam. Thus, this presentation aims to introduce a new implementation of facial recognition in digiKam, based on deep learning models and OpenCV DNN module, so as to improve the performance of facial recognition module.

How can a community like KDE benefit from a developer portal...and what is a developer portal, anyway? This talk aims to answer those questions, and offers practical advice for building a developer portal. The insights from this session can serve as guidance and inspiration to all contributors who want to make sure their community keeps growing and thriving.
