How to build a multiple file upload form using HTML
How to handle file uploads securely with PHP (latest version)
How to store file names in a MariaDB database
How to manage uploads: insert, update, and delete records
Best practices for secure and clean file handling

Step 1: Create the HTML Upload Form




&lt;form action=&quot;&quot; method=&quot;post&quot; enctype=&quot;multipart/form-data&quot;&gt;
   &lt;label&gt;Select files to upload:&lt;/label&gt;
   &lt;input type=&quot;file&quot; name=&quot;files[]&quot; multiple /&gt;
   &lt;input type=&quot;submit&quot; name=&quot;submit&quot; value=&quot;Upload Files&quot;&gt;
&lt;/form&gt;

Step 2: PHP Script to Handle Multiple File Uploads (upload.php)




$host = &#039;localhost&#039;;
$db = &#039;file_uploads&#039;;
$user = &#039;your_user&#039;;
$pass = &#039;your_password&#039;;

$conn = new mysqli($host, $user, $pass, $db);

if ($conn-&gt;connect_error) {
    die(&quot;Connection failed: &quot; . $conn-&gt;connect_error);
}

$uploadDir = &quot;uploads/&quot;;
$allowedTypes = [&#039;avif&#039;, &#039;jpg&#039;, &#039;jpeg&#039;, &#039;png&#039;, &#039;gif&#039;, &#039;pdf&#039;];

if (isset($_POST[&#039;submit&#039;]) &amp;&amp; !empty($_FILES[&#039;files&#039;][&#039;name&#039;][0])) {
    foreach ($_FILES[&#039;files&#039;][&#039;name&#039;] as $key =&gt; $name) {
        $tmpName = $_FILES[&#039;files&#039;][&#039;tmp_name&#039;][$key];
        $error = $_FILES[&#039;files&#039;][&#039;error&#039;][$key];
        $size = $_FILES[&#039;files&#039;][&#039;size&#039;][$key];

        $ext = strtolower(pathinfo($name, PATHINFO_EXTENSION));
        
        if ($error === 0 &amp;&amp; in_array($ext, $allowedTypes)) {
            $newName = uniqid() . &#039;.&#039; . $ext;
            $uploadPath = $uploadDir . $newName;

            if (move_uploaded_file($tmpName, $uploadPath)) {
               $stmt = $conn-&gt;prepare(&quot;INSERT INTO uploads (filename) VALUES (?)&quot;);
               $stmt-&gt;bind_param(&quot;s&quot;, $newName);
               $stmt-&gt;execute();
               $stmt-&gt;close();
               //echo &quot;$name uploaded successfully.&lt;br&gt;&quot;;
               header(&quot;Location: &quot; . $_SERVER[&#039;PHP_SELF&#039;]);
               exit;
            } else {
               echo &quot;Error uploading $name.&lt;br&gt;&quot;;
            }
        } else {
            echo &quot;$name is not a valid file type or has an error.&lt;br&gt;&quot;;
        }
    }
} else {
    echo &quot;No files selected.&quot;;
}

$conn-&gt;close();

Step 3: MariaDB Table Structure

CREATE TABLE uploads (
    id INT AUTO_INCREMENT PRIMARY KEY,
    filename VARCHAR(255) NOT NULL,
    uploaded_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

Bonus: Updating and Deleting Files

You can add update and delete features using simple SQL queries like:

Delete File

$stmt = $conn-&gt;prepare("DELETE FROM uploads WHERE id = ?");
$stmt-&gt;bind_param("i", $id);
$stmt-&gt;execute();

Update File Name

$stmt = $conn-&gt;prepare("UPDATE uploads SET filename = ? WHERE id = ?");
$stmt-&gt;bind_param("si", $newFilename, $id);
$stmt-&gt;execute();

Always remember to remove the file from the server using:

unlink('uploads/' . $filename);

Best Practices

Always validate file types to avoid malicious uploads
Store files outside the web root if possible
Rename files to avoid name collisions
Use prepared statements to protect against SQL injection
Limit file size and number of files uploaded at once

CSS3 Full-Page Scroll Animation with No JavaScript
HTML5 CS3 Scroll Moves Down Then Right

If you have ever wanted to create a visually engaging scroll animation without using JavaScript, this beginner tutorial is for you. Using only HTML5 and CSS3, we will build a full-width, full-height animation where the page content scrolls right, then down, then right again – perfect for highlighting backgrounds, image slides, or portfolios.

This layout is great for personal projects, design showcases, or portfolios. And the best part? No JavaScript is required.

What We Will Build

We will create a simple layout using CSS3 animations and the @keyframes rule to achieve a scroll-like effect. Here is the motion path:
- First, scroll right across a full-screen section.
- Then, scroll down to the next screen.
- Finally, scroll right again to a third section.
This effect is often called a “scroll path” and can be built entirely with CSS animations.

HTML Structure
```
  &lt;div class=&quot;container&quot;&gt;
    &lt;section class=&quot;screen screen1&quot;&gt;Section 1&lt;/section&gt;
    &lt;section class=&quot;screen screen2&quot;&gt;Section 2&lt;/section&gt;
    &lt;section class=&quot;screen screen3&quot;&gt;Section 3&lt;/section&gt;
  &lt;/div&gt;
```
CSS3 Animations (styles.css)
```
html, body {
  margin: 0;
  padding: 0;
  overflow: hidden;
  height: 100%;
  width: 100%;
  font-family: sans-serif;
}

.container {
  display: flex;
  height: 100vh;
  width: 300vw;
  animation: moveScroll 15s linear infinite;
  position: relative;
}

.screen {
  flex: 0 0 100vw;
  height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
  font-size: 3em;
  color: white;
}

.screen1 { background: #1abc9c; }
.screen2 { background: #e74c3c; }
.screen3 { background: #3498db; }

@keyframes moveScroll {
  0% { transform: translateX(0); }
  33% { transform: translateX(-100vw); }
  66% { transform: translate(-100vw, -100vh); }
  100% { transform: translate(-200vw, -100vh); }
}
```

Generate Low-Poly Hammer With Blender Python API For Website
Create a 3D Hammer with Blender Python API and Display It on Your Website

Welcome to this beginner-friendly tutorial! Today, we will explore how to generate a simple 3D hammer model using Blender’s Python API and display it directly in your web browser using the <model-viewer> web component. This approach combines the power of Blender scripting with modern web technologies to bring interactive 3D content to your site.

Step 1: Generating a Hammer Model with Blender Python API

Blender is a fantastic open-source 3D modeling tool that supports scripting through Python. With just a few lines of code, you can programmatically create objects like a hammer.

Here is an improved example of a Blender Python script to generate a claw hammer with wood and metal materials:
```
import bpy
import bmesh
from mathutils import Vector

# Clear existing objects
bpy.ops.object.select_all(action=&#039;SELECT&#039;)
bpy.ops.object.delete(use_global=False)

# Create materials
def create_material(name, base_color, metallic=0.0, roughness=0.5):
    mat = bpy.data.materials.new(name)
    mat.use_nodes = True
    principled = mat.node_tree.nodes.get(&#039;Principled BSDF&#039;)
    principled.inputs[&#039;Base Color&#039;].default_value = base_color
    principled.inputs[&#039;Metallic&#039;].default_value = metallic
    principled.inputs[&#039;Roughness&#039;].default_value = roughness
    return mat

wood_mat = create_material(&#039;Wood&#039;, (0.36, 0.20, 0.08, 1), metallic=0.0, roughness=0.7)
metal_mat = create_material(&#039;Metal&#039;, (0.8, 0.8, 0.8, 1), metallic=1.0, roughness=0.2)

# Create handle (cylinder)
bpy.ops.mesh.primitive_cylinder_add(radius=0.1, depth=2, location=(0, 0, 1))
handle = bpy.context.object
handle.name = &#039;Handle&#039;
handle.data.materials.append(wood_mat)

# Create hammer head (cube)
bpy.ops.mesh.primitive_cube_add(size=0.5, location=(0, 0, 2.25))
head = bpy.context.object
head.name = &#039;Head&#039;
head.data.materials.append(metal_mat)

# Edit mode: shape the head to a claw hammer by bending and beveling
bpy.context.view_layer.objects.active = head
bpy.ops.object.mode_set(mode=&#039;EDIT&#039;)
mesh = bmesh.from_edit_mesh(head.data)

# Select vertices on one side of the cube to form the claw curve
for v in mesh.verts:
    if v.co.x &gt; 0:
        v.co += Vector((0.2, 0.0, -0.1 * (v.co.z - 0.25)))

bmesh.update_edit_mesh(head.data)
bpy.ops.mesh.bevel(offset=0.05, segments=4, profile=1)
bpy.ops.object.mode_set(mode=&#039;OBJECT&#039;)

# Slightly rotate the head to mimic claw hammer angle
head.rotation_euler[1] = 0.3  # Rotate around Y axis

# Join handle and head
bpy.ops.object.select_all(action=&#039;DESELECT&#039;)
handle.select_set(True)
head.select_set(True)
bpy.context.view_layer.objects.active = handle
bpy.ops.object.join()

# Export as GLB
bpy.ops.export_scene.gltf(filepath=&quot;hammer.glb&quot;, export_format=&#039;GLB&#039;)
```
Step 2: Running the Python Script from the Command Line

To generate the hammer model, save the above script as generate_hammer.py. You can run it using Blender’s command line interface:
```
blender --background --python generate_hammer.py
```
- --background runs Blender without its graphical interface.
- --python runs your script.
This command will create a hammer.glb file in the same directory.

Step 3: Displaying the Hammer Model on Your Website Using <model-viewer>

Once you have the hammer.glb file, you can embed it into any webpage easily with the <model-viewer> web component, which supports interactive 3D models in browsers.

Here is an example HTML snippet:
```
&lt;script type="module" src="https://unpkg.com/@google/model-viewer/dist/model-viewer.min.js"&gt;&lt;/script&gt;

&lt;model-viewer src="hammer.glb" alt="3D Hammer Model" auto-rotate camera-controls background-color="#FFFFFF" style="width: 400px; height: 400px;"&gt;&lt;/model-viewer&gt;
```
Simply place the hammer.glb file on your web server alongside this HTML file, and visitors will see your interactive 3D hammer right in their browser!

Get Started with Gitolite: Open Source Git Hosting on Your Own Server (Using Podman)
Host Your Own Git Server with Gitolite and Podman

Want to run your own Git server without relying on GitHub, GitLab, or Bitbucket? Gitolite is a powerful, open-source tool that lets you manage Git repositories on your own terms – with SSH-based access control, fine-grained permissions, and no need for a web interface.

In this post, I will show you how to install Gitolite inside a Podman container, taking full advantage of official repositories.

Why Gitolite?
- Self-hosted Git server
- Fine-grained access control using SSH keys
- Lightweight and scriptable
- 100% open source
Step 1: Prepare Your Admin SSH Key

You’ll need your SSH public key for administration. Save it as admin.pub in the same folder where you create the container files.

Step 2: Create the Containerfile

Create a file named Containerfile (or Dockerfile) with the following content:
```
FROM alpine:latest

# Install required packages
RUN apk add --no-cache git gitolite openssh

# Prepare SSH and home directory
RUN mkdir -p /var/run/sshd /home/git/.ssh &amp;&amp; \
    chown -R git:git /home/git

# Generate SSH host keys
RUN ssh-keygen -A

# Copy your public key into the image
COPY admin_key.pub /tmp/admin_key.pub
RUN chown git:git /tmp/admin_key.pub

# Run gitolite setup as git user
RUN su git -c "gitolite setup -pk /tmp/admin_key.pub"

# Copy SSHD config (rootless-safe)
COPY sshd_config /etc/ssh/sshd_config

# Expose high port for rootless podman
EXPOSE 2222

CMD ["/usr/sbin/sshd", "-D", "-e"]
```
Step 3: Create the podman-compose.yml File

Create a podman-compose.yml file alongside the Containerfile:
```
version: "3.9"

services:
  gitolite:
    build: .
    container_name: gitolite
    ports:
      - "2222:2222"
    volumes:
      - gitolite_data:/home/git
    restart: unless-stopped

volumes:
  gitolite_data:
```
Step 4: Build and Run Your Gitolite Container
1. Build the container image:
```
podman-compose build
```
2. Start the container:
```
podman-compose up -d
```
3. Your Gitolite server will be running and accessible on port 2222.
Step 5: Connect to Your Gitolite Server

From your host machine, clone the Gitolite admin repository using:
```
git clone ssh://git@localhost:2222/gitolite-admin
```
Now you can manage your repositories, users, and permissions by editing the Gitolite config and pushing changes.

Review Generative AI DeepSeek-R1 32B Model
How to Run Ollama with DeepSeek-R1 32B LLM on Fedora 42 – Open Source AI for Everyone

Introduction

In this post, we will walk through the steps to get Ollama running on your system, with a special focus on using the DeepSeek-R1 32B LLM. This open-source model offers an impressive combination of text generation and deep learning power, and it is easy to integrate into your own projects. Whether you are a beginner or a seasoned developer, you will be able to follow along.

This guide includes step-by-step instructions for installing the necessary dependencies on Fedora 42, along with an example Python script that interacts with the Ollama API to run the DeepSeek-R1 32B model.

What is Ollama and DeepSeek-R1 32B?

Ollama is a platform designed for running and interacting with various AI models locally. It is open-source and highly flexible, making it perfect for running Large Language Models (LLMs) like DeepSeek-R1 32B.
- DeepSeek-R1 32B is a powerful 32 billion parameter language model that can be used for tasks like natural language generation, question answering, summarization, and more.
- Open Source License: DeepSeek-R1 is released under the MIT License, which means you can use, modify, and distribute it freely.
Installation Guide for Fedora 42

Step 1: Install Dependencies

To get started, install Ollama and the required dependencies:
```
# Install Python 3 and pip
sudo dnf install python3 python3-pip

# Install other necessary tools
sudo dnf install git curl

# Install the Ollama client
pip install ollama
```
Fedora 42 includes Ollama in the official repositories. You can install it easily using the system package manager.
```
# 1. Update your system
sudo dnf update -y

# 2. Install Ollama
sudo dnf install -y ollama

# 3. Start the Ollama service
ollama serve &
```
Ollama makes it incredibly simple to run LLMs locally with minimal setup, providing an intuitive CLI and REST API to interact with models like Meta’s LLaMA.

Step 2: Install DeepSeek-R1 32B Model

Download and set up the model locally:
```
ollama pull deepseek-r1:32b
```
Step 3: Increase System Swap Space (If Needed)

To prevent memory errors, increase swap space:
```
# Check current swap space
swapon --show

# Increase swap size by 4GB
sudo dd if=/dev/zero of=/swapfile bs=1M count=4096
sudo mkswap /swapfile
sudo swapon /swapfile
```
Using the Ollama API with Python

Below is a sample Python script that sends a prompt to the Ollama API and displays the response:
```
import requests

def ask_ollama(prompt):
    url = &quot;http://localhost:11434/api/generate&quot;
    payload = {
        &quot;model&quot;: &quot;deepseek-r1:32b&quot;,
        &quot;prompt&quot;: prompt
    }
    
    response = requests.post(url, json=payload)
    
    try:
        return response.json()[&quot;response&quot;]
    except Exception as e:
        print(f&quot;Error: {e}&quot;)
        return None

if __name__ == &quot;__main__&quot;:
    question = &quot;What is the capital of Canada?&quot;
    answer = ask_ollama(question)
    
    if answer:
        print(&quot;Answer:&quot;, answer)
    else:
        print(&quot;No answer returned.&quot;)
```
Explanation

This script sends a prompt to the local Ollama server using the DeepSeek-R1 32B model. It handles basic error checking and prints the model’s response.
