Traditionally, developers have scattered code snippets across their models to handle type casting, leading to cluttered and less maintainable code. However, with the introduction of Laravel 11, a game-changing feature called the casts method has arrived to streamline this process and enhance code organization.<span><a name='more'></a></span><p></p><h3 style="text-align: left;">Introducing the <span style="font-family: courier;">casts</span> Method</h3><p>The casts method, introduced in Laravel 11, provides a centralized location within your model class to define type casting for various attributes. This means you no longer need to scatter type casting logic throughout your model's methods, significantly improving code organization and readability.</p><p>Let's take a closer look at how the casts method works in practice:</p><p><span style="font-family: courier;">class User extends Model</span></p><p><span style="font-family: courier;">{</span></p><p><span style="font-family: courier;"> protected $casts = [</span></p><p><span style="font-family: courier;"> 'created_at' => 'datetime',</span></p><p><span style="font-family: courier;"> 'updated_at' => 'datetime',</span></p><p><span style="font-family: courier;"> ];</span></p><p><span style="font-family: courier;">}</span></p><p>In the above example, we define the $casts property within the User model class. This property is an associative array where the keys represent the names of the attributes you want to cast, and the values specify the desired data types for those attributes.</p><p>In this case, both the created_at and updated_at attributes are cast to the datetime data type. This ensures that whenever you access these attributes, Laravel automatically casts them to instances of the DateTime class, simplifying date and time manipulation in your application.</p><h3 style="text-align: left;">Benefits of Using the casts Method</h3><p>By leveraging the casts method in Laravel 11, developers can enjoy several benefits:</p><p></p><ul style="text-align: left;"><li>Centralized Configuration: All type casting logic is consolidated within the $casts property of the model class, making it easy to locate and manage.</li><li>Improved Readability: With type casting definitions clearly defined in one place, code becomes more readable and maintainable, enhancing developer productivity.</li><li>Reduced Code Duplication: Eliminates the need to repeat type casting logic across multiple methods or models, reducing code duplication and promoting DRY (Don't Repeat Yourself) principles.</li><li>Enhanced Data Integrity: By explicitly defining data types for attributes, the casts method helps maintain data integrity and consistency throughout your application.</li></ul><p></p><h3 style="text-align: left;">Conclusion</h3><p>The introduction of the casts method in Laravel 11 represents a significant improvement in data type casting management for Laravel developers. By providing a centralized approach to defining type casting logic within model classes, Laravel streamlines code organization, improves readability, and enhances developer productivity.</p><p>If you're working with Laravel 11 or planning to upgrade, be sure to leverage the casts method to streamline your data type casting workflow and take your Laravel applications to the next level of elegance and efficiency!</p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-7500037502820397538.post-4127241810808508932024-03-19T03:27:00.000-07:002024-03-19T03:27:44.033-07:00How to Fix HTTP Error 404 in XAMPP: 5 Tips to Get Your Development Back on Track<p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhC26Zn03R3N18d6fiqj3DZ2zD8LdKwyhu4-kWEJcHi1jHmCJQO_c3yUgflQKm7GWbT5Q9q05il8B19nKoYBAb_Hoj3c4b_Ed-oDyKKLis-XgO-VdywPQ03IPAi4d6A5SynrR4-eGrVzLfjaXabZXqpSPqsSGDGROQ5rnkZcoBUHymgOlXLyfd1fWkXXAI/s668/logo-xampp.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="434" data-original-width="668" height="208" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhC26Zn03R3N18d6fiqj3DZ2zD8LdKwyhu4-kWEJcHi1jHmCJQO_c3yUgflQKm7GWbT5Q9q05il8B19nKoYBAb_Hoj3c4b_Ed-oDyKKLis-XgO-VdywPQ03IPAi4d6A5SynrR4-eGrVzLfjaXabZXqpSPqsSGDGROQ5rnkZcoBUHymgOlXLyfd1fWkXXAI/s320/logo-xampp.png" width="320" /></a></div><br /> Encountering the dreaded “HTTP Error 404 – The Requested Resource Is Not Found” in XAMPP can be frustrating, especially when you’re in the midst of development. However, fear not – we've compiled five effective tips to help you troubleshoot and resolve this common issue. Let's dive in!<p></p><span><a name='more'></a></span><p><br /></p><p>1. Double-Check the URL</p><p>Before diving into complex fixes, start with the basics. Ensure that you've entered the URL correctly without any typos or unnecessary additions. A simple mistake in the URL, such as including “XAMPP” when it’s not required, can trigger the error.</p><p><br /></p><p>2. Verify the .htaccess File</p><p>A missing or misconfigured .htaccess file can also lead to a 404 error. Navigate to the XAMPP folder on your system, locate the htdocs folder, and ensure that the .htaccess file exists there. If not, create one and populate it with appropriate code, such as WordPress-specific directives, to rectify the issue.</p><p>Wordpress htaccess example:<br /></p><p><span style="font-family: courier;"># BEGIN WordPress</span></p><p><span style="font-family: courier;">RewriteEngine On</span></p><p><span style="font-family: courier;">RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]</span></p><p><span style="font-family: courier;">RewriteBase /</span></p><p><span style="font-family: courier;">RewriteRule ^index.php$ - [L]</span></p><p><span style="font-family: courier;">RewriteCond %{REQUEST_FILENAME} !-f</span></p><p><span style="font-family: courier;">RewriteCond %{REQUEST_FILENAME} !-d</span></p><p><span style="font-family: courier;">RewriteRule . /index.php [L]</span></p><p><span style="font-family: courier;"># END WordPress</span></p><p><br /></p><p>3. Deactivate or Uninstall New Plugins</p><p>Newly installed plugins can sometimes wreak havoc on your site, causing unexpected errors like the 404.

This innovative technique allows the trojan to evade detection on recent Android versions up to 14, making it particularly stealthy and challenging to detect.<span></span></p><a name='more'></a><p></p><p>According to a recent report by IBM Trusteer researchers, PixPirate employs a two-pronged attack strategy involving a downloader app and a payload app ('droppee') to infiltrate and compromise devices. The downloader app, distributed through malicious APKs spread via phishing messages, requests risky permissions upon installation, including Accessibility Services. Once installed, it proceeds to download and install the encrypted PixPirate malware without displaying any visible icon.</p><p>The 'droppee' app, devoid of a main activity declaration in its manifest, further conceals its presence by not displaying an icon on the home screen. Instead, it exports a service that the downloader app connects to trigger the launch of the malware covertly. This allows PixPirate to execute in the background, even if the downloader app is removed by the victim.</p><p>PixPirate's malicious activities primarily target the Brazilian instant payment platform Pix, aiming to siphon funds by intercepting or initiating fraudulent transactions.

It wasn't until a month later that Stanford publicly disclosed the ongoing investigation.</p><span><a name='more'></a></span><p>In a recent update shared on Monday, Stanford disclosed that the attackers had infiltrated the Department of Public Safety's network between May 12, 2023, and September 27, 2023. However, the investigation confirmed that the unauthorized access was limited to this specific network, with no breach detected in other systems outside the department.</p><p>According to data breach notifications submitted to Maine's Attorney General, the attackers managed to access documents containing personally identifiable information (PII) of the affected 27,000 individuals.</p><p>Stanford further elaborated that the compromised personal information varied among individuals but could potentially include sensitive data such as dates of birth, Social Security numbers, government IDs, passport numbers, driver's license numbers, and other details collected by the Department of Public Safety in its operations.</p><p>For a select few, the compromised information might have extended to biometric data, health or medical records, email addresses with passwords, usernames with passwords, security question responses, digital signatures, and credit card details with security codes.</p><p>While Stanford has not officially linked the September incident to a specific ransomware group, the Akira ransomware gang claimed responsibility for the attack in October. They asserted that they had pilfered 430GB of files from the university's systems.</p><p>Subsequently, the cybercriminal group published the stolen data on their dark web leak site, making it accessible for download via BitTorrent.</p><p>The Akira ransomware operation emerged in March 2023 and rapidly gained notoriety for targeting victims across various sectors. By June 2023, the group had developed and deployed a Linux encryptor specifically designed to target VMware ESXi virtual machines commonly used in corporate environments.</p><p>Negotiation chats reviewed by BleepingComputer indicate that the ransomware group is demanding ransom payments ranging from $200,000 to millions of dollars, depending on the size and scope of the breached organization.</p><p>This incident marks the latest in a series of data breaches suffered by Stanford University. In February 2023, the university disclosed another breach after sensitive information related to its Department of Economics Ph.D. program admissions was exposed online. Additionally, in April 2021, the Clop ransomware group leaked documents stolen from Stanford School of Medicine's Accellion File Transfer Appliance (FTA) platform.</p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-7500037502820397538.post-33121695265178418032024-03-17T19:51:00.000-07:002024-03-17T19:51:46.023-07:00Windows 10 KB5035845 Update: What's New?<p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3Up2zz_sU-Z9CkX1wiUoI4o0rRm3NoE4InOwaLG6HR2Z3aTSK3F-dDSRivbzG0jFd1v75mhL_y_6ICaoNX6_qYXX7s_h7CgaVTDn4Qei-6WSEXnchhiMvf23GyevhIztySTmL4FDsuz46HNAXEzKKkmrp0qm-wk6Cp9KEHMgZ06-1bU1ute2Y45DglNQ/s420/logo-windows.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="89" data-original-width="420" height="68" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3Up2zz_sU-Z9CkX1wiUoI4o0rRm3NoE4InOwaLG6HR2Z3aTSK3F-dDSRivbzG0jFd1v75mhL_y_6ICaoNX6_qYXX7s_h7CgaVTDn4Qei-6WSEXnchhiMvf23GyevhIztySTmL4FDsuz46HNAXEzKKkmrp0qm-wk6Cp9KEHMgZ06-1bU1ute2Y45DglNQ/s320/logo-windows.png" width="320" /></a></div><br />Microsoft has rolled out the latest Windows 10 KB5035845 update, bringing nine fixes and enhancements to the operating system.

But that's not all - since my exciting win at GeeCON Prague, I've also become the proud owner of a Raspberry Pi. So, naturally, I decided to experiment with self-hosted runners for GitHub Actions. Here's what I discovered along the way.<p></p><p>GitHub Actions offers extensive free usage, but the landscape can change at any time. As a proactive measure, I wanted to explore alternatives before the need to migrate arises. This led me to delve into the world of self-hosted runners.<span></span></p><a name='more'></a><p></p><p>Self-hosted runners offer a flexible alternative to GitHub's default runners. They allow you to configure your jobs to run on your own infrastructure, whether on-premise or in the Cloud. While the documentation provides all the necessary details for setting up self-hosted runners, there were a couple of challenges I encountered during the process.</p><p>One of the key realizations I had was that GitHub Actions depend on Docker being installed on the runner. This meant that whatever script I ran in my job would execute on the running system, rather than in a dedicated image. As a result, I had to make adjustments to my initial setup, including downgrading Python to match the version installed on Raspbian, the default operating system for Raspberry Pi.</p><p>Here's the updated version of the script:</p><p><span style="font-family: courier;">jobs:</span></p><p><span style="font-family: courier;"> update:</span></p><p><span style="font-family: courier;"> runs-on: ubuntu-latest</span></p><p><span style="font-family: courier;"> steps:</span></p><p><span style="font-family: courier;"> - name: Set up Python 3.x</span></p><p><span style="font-family: courier;"> uses: actions/setup-python@v5</span></p><p><span style="font-family: courier;"> with:</span></p><p><span style="font-family: courier;"> python-version: 3.11</span></p><p><span style="font-family: courier;"> - name: Set up Poetry</span></p><p><span style="font-family: courier;"> uses: abatilo/actions-poetry@v2</span></p><p><span style="font-family: courier;"> with:</span></p><p><span style="font-family: courier;"> poetry-version: 1.7.1</span></p><h4 style="text-align: left;">Handling Secrets and Environment Variables</h4><p>Setting up secrets and environment variables posed another challenge. While on GitHub, you set secrets via the GUI and reference them in your scripts, self-hosted runners require a different approach. Environment variables are set in an existing .env file within the folder, allowing for a more segregated setup.</p><p>Here's how you can reference environment variables in your script:</p><p><span style="font-family: courier;">jobs:</span></p><p><span style="font-family: courier;"> update:</span></p><p><span style="font-family: courier;"> runs-on: ubuntu-latest</span></p><p><span style="font-family: courier;"> steps:</span></p><p><span style="font-family: courier;"> - name: Update README</span></p><p><span style="font-family: courier;"> run: poetry run python src/main.py --live</span></p><p><span style="font-family: courier;"> env:</span></p><p><span style="font-family: courier;"> BLOG_REPO_TOKEN: ${{ secrets.BLOG_REPO_TOKEN }}</span></p><p><span style="font-family: courier;"> YOUTUBE_API_KEY: ${{ secrets.YOUTUBE_API_KEY }}</span></p><h4 style="text-align: left;">Making the Runner a Service</h4><p>Lastly, to ensure seamless operation, I needed to configure the runner as a service using built-in scripts provided by GitHub. This involved installing and starting the service using systemd.</p><p>Here are the commands to make the runner a service:</p><p><span style="font-family: courier;">sudo ./svc.sh install</span></p><p><span style="font-family: courier;">sudo ./svc.sh start</span></p><h3 style="text-align: left;">Conclusion</h3><p>While migrating to a self-hosted runner presented some challenges, it was a valuable learning experience. Understanding that the script runs on the machine itself was a crucial insight, prompting me to explore options for automating the provisioning of new machines in case of crashes. For now, I've decided to hold off on migrating more jobs to self-hosted runners, but I'm open to exploring containerized solutions in the future. If you've come across any such solutions or have any insights to share, I'd love to hear from you. In the meantime, I'll continue to tinker and experiment with GitHub Actions on my Raspberry Pi.</p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-7500037502820397538.post-36257296691417018262024-03-17T19:32:00.000-07:002024-03-17T19:32:33.503-07:00 Introducing LogicAnalyzer: A Budget-Friendly 24-Channel Logic Analyzer Running on Raspberry Pi<p>Meet Agustín Gimenez Bernad, the brains behind LogicAnalyzer, an affordable yet powerful tool designed for electronics enthusiasts and professionals alike.
