Web Security Best Practices and Trends in Enterprise App Development: Safeguarding Business Data
Published: 2024-05-08 11:09:33

In today's rapidly evolving digital landscape, enterprise applications play a pivotal role in driving business efficiency and innovation. However, with the increasing reliance on enterprise apps comes the critical need to prioritize security measures to safeguard sensitive business data and mitigate potential threats. In this post, we'll delve into some of the best practices for enhancing enterprise app security and explore key takeaways for ensuring robust protection against cyber threats.

## Key Takeaways
1. **Adopting Security by Design:** Integrating security considerations at every stage of the development process is crucial for proactively mitigating risks. By prioritizing security from the initial planning and design phase, enterprises can build a solid foundation that is inherently secure.
2. **Implementing Secure Coding Practices:** Developers must adhere to secure coding practices such as strong access control, multi-factor authentication (MFA), and regular security audits to minimize the risk of exploitation and ensure the integrity of enterprise applications.
3. **Leveraging Industry-Recognized Standards and Frameworks:** Adherence to security standards and frameworks such as OWASP, PCI DSS, and ISO 27001 enhances overall security posture and demonstrates a commitment to data protection.
4. **Staying Vigilant Against Evolving Threats:** Enterprises must remain vigilant against evolving security threats and vulnerabilities by staying informed about the latest trends and continuously updating security measures to address new challenges.
5. **Utilizing Security Middleware:** Tools like Helmet middleware for Express.js can significantly enhance application security by enforcing critical security headers and protective measures, thereby adding an extra layer of defense against common web vulnerabilities.

## Conclusion
In conclusion, prioritizing security in enterprise app development is imperative for protecting sensitive business data and maintaining the trust of customers. By implementing security best practices, leveraging industry standards, and staying informed about emerging threats, enterprises can enhance their security posture and mitigate potential risks effectively.

TW Elements - Rounded corners / border radius. Free UI/UX design course
Tags: webdev, tailwindcss, beginners, ui
Published: 2024-05-08 11:00:00

## Rounded corners / border radius
This lesson will be easy, sweet, and short. We will learn how to add rounded corners in Tailwind CSS and use the border radius property.

Rounded corners are a detail, but very important in design.

**Note:** _In design theory, rounded corners require less cognitive (i.e. related to learning and understanding reality) effort. They also look friendlier to us. Why?_

This is related to the so-called "contour bias", which makes us associate sharp edges with danger (like the fangs and claws of a wild animal, which our ancestors lived in fear of). In contrast to them, there are gentle and rounded edges, which seem more friendly and safe to us.

## How to add border radius?
In CSS, the border-radius property is responsible for rounded corners.

In Tailwind CSS, it's very easy to add rounded corners to any element and manipulate the border-radius property.

Just add class rounded- + size to the element. You have sizes from none (removes rounded corners) up to full, so to add for example slightly rounded corners you can use class rounded-md or similar.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/nmx6x8rhrejpa3p5tklc.png)

HTML

```
<!-- border-radius: 0px; -->
<img src="..." class="rounded-none" alt="..." />

<!-- border-radius: 0.125rem; -->
<img src="..." class="rounded-sm" alt="..." />

<!-- border-radius: 0.25rem; -->
<img src="..." class="rounded" alt="..." />

<!-- border-radius: 0.375rem; -->
<img src="..." class="rounded-md" alt="..." />

<!-- border-radius: 0.5rem; -->
<img src="..." class="rounded-lg" alt="..." />

<!-- border-radius: 0.75rem; -->
<img src="..." class="rounded-xl" alt="..." />

<!-- border-radius: .1rem; -->
<img src="..." class="rounded-2xl" alt="..." />

<!-- border-radius: 1.5rem; -->
<img src="..." class="rounded-3xl" alt="..." />

<!-- border-radius: 9999px; -->
<img src="..." class="rounded-full" alt="..." />
```

## Add rounded corners to the carousel
Now let's add rounded corners to our carousel via the .rounded-2xl class.

To modify the appearance of the carousel, we need to add the rounded-2xl class to the Carousel items part.

HTML

```
<!--Carousel items-->
<div
  class="relative w-full overflow-hidden rounded-2xl after:clear-both after:block after:content-['']">
  [...]
</div>
```

After saving the file and refreshing your browser, you'll see that our carousel now has cute rounded corners.

b = text.endswith("i")
c = text.islower()

if all([a, b, c]):

👉 **B.** 👌

En Python tenemos palabras clave para agrupar un conjunto de condiciones, en este caso vemos `all` que significa que todas las condiciones tienen que evaluar a `True` para que pase y se ejecute el bloque de código siguiente.

En nuestro ejemplo la palabra `hi` cumple las condiciones `a`, `b` y `c` por lo tanto pasa y se ejecuta el if.

Create a User With Access to Only One Schema in CloudSQL
Tags: googlecloud, mysql, cloudsql
Published: 2024-05-08 10:55:46

**TL;DR:** After you create a user in Google Cloud Console, don't forget to `REVOKE 'cloudsqlsuperuser'@'%' FROM 'your-user'@'%';` if you only want this user to access specific schemas.

---

Creating a MySQL user via the Google Cloud Console automatically adds the `cloudsqlsuperuser` role that allows the user access to everything on that MySQL instance:

```sql
SHOW GRANTS FOR 'user-from-gcp-console'@'%';

+------------------------------------------------------------+
|Grants for user-from-gcp-console@%                          |
+------------------------------------------------------------+
|GRANT USAGE ON *.* TO `user-from-gcp-console`@`%`           |
|GRANT `cloudsqlsuperuser`@`%` TO `user-from-gcp-console`@`%`|
+------------------------------------------------------------+
```

Google mentions this in the [About MySQL users](https://cloud.google.com/sql/docs/mysql/users#cloudsqlsuperuser) article of their Knowledge Base.

To create a user with access to only one schema, you either need to create the user without the console by running something along the lines of:

```sql
CREATE USER 'your-user'@'%' IDENTIFIED
    WITH 'mysql_native_password'
    BY '<some-strong-password>';

GRANT ALL ON your-schema.* TO 'your-user'@'%';
```

Or by creating the user via the console but then not forgetting to remove the `cloudsqlsuperuser` role:

```
// Create a user via the Google Cloud Console

REVOKE 'cloudsqlsuperuser'@'%' FROM 'your-user'@'%';
GRANT ALL ON your-schema.* TO 'your-user'@'%';
```

---

### Closing notes

- The user is uniquely identified by the user name and the host. `%` stands for any host, the commands might differ when you’re limiting the user access only to some hosts (e.g. `your-user%localhost`).
- You might make use of the Cloud SQL Proxy in combination with IAM instead. Read more in the [IAM Authentication](https://cloud.google.com/sql/docs/mysql/iam-authentication) article.
- There is now also the [Cloud SQL Studio](https://cloud.google.com/sql/docs/mysql/manage-data-using-studio) [in preview] that might come in handy.

🚀 **Day 15 of my journey to becoming an L5-L6 developer!**

📚 **Topics Covered So Far:**

1. Array & Hashing
2. Two Pointers
3. Sliding Window
4. Stack
5. Binary Search
6. Queue
7. Priority Queue
8. Linked List
9. Trees
10. Recursion
11. Graphs
12. Dynamic Programming
13. Backtracking

🎩 **Pro Tips & Personal Insights:**

- **Two Pointers:** Like sliding windows, but with limited pointers. Great for optimizing solutions.
- **Sliding Window:** Start with a valid window, add items, and remove them if the window becomes invalid.
- **Stack:** Think of it as a place to store things for later, in reverse recursive order.
- **Binary Search:** The magic of reducing your domain on every step to find the item efficiently.
- **Linked List:** A node that knows only about its adjacent nodes.
- **Trees:** Do things for one node, then make it recursive for all. Like a domino effect!
- **Recursion:** A powerful tool to solve problems by breaking them down into smaller, manageable pieces.
- **Dynamic Programming:** Solve via recursion, add cache, convert into iterative solution, then optimize space. Voila!
- **Backtracking:** When you need to explore all possible solutions without getting lost. Think of it as your problem-solving GPS.

Here’s a neat trick for backtracking:

```
backtrack_arr = []
def rec(i):
    backtrack_arr.append(s[i])
    rec(i+1)
    backtrack_arr.pop()

```

## What I built
I build Instagram AI bot. I use openAI for creating prompt and image. Bot will create new image every day and post it on Instagram. It will also upload image to Cloudinary as backup.
It's all run on Linode server as express app.

### Category Submission:

Yes, AI also create my avatar.

### Description
 Hi, I am The Cyber Painter. I use openAI to create art. Yap, every day I will paint a new image and post it on Instagram. 

### Link to Source Code

## Background
All that AI hype is crazy. I want to take a part so I decide to create art (maybe someone will like it). Let's see what new will bring us.


### How I built it
Linode is a great tool. I am still learning it. There is so many ways to use it. I watch some YouTube tutorials like this https://youtu.be/sD8X4CApdpo and they really help me to build it. 
Spoiler alert - it's super easy :)

Optimistic lock & Pessimistic lock
Tags: database
Published: 2024-05-08 10:27:15

## Pessimistic lock
- Lock
- READ
- UPDATE
- Unlock

Example:

```sql
START TRANSACTION;

-- Select the product row for update
SELECT * FROM products WHERE product_id = 1 FOR UPDATE;

-- Perform operations on the selected data
UPDATE products 
SET price = 1200,
  version = version + 1
WHERE product_id = 1;

-- Commit the transaction
COMMIT;
```

#### PROs:
- Prevents conflicts.
- Ensures data integrity.
- Suitable for high contention.

#### CONs:
- Decreased throughput.
- Increased deadlock risk.
- Reduced responsiveness.

#### Use Case:
Pessimistic locking is often employed in scenarios where conflicts are likely or must be avoided, such as:
- Banking systems where transactions involving account balances must be processed serially.
- Reservation systems where concurrent bookings for the same resource must be prevented.

## Optimistic lock
- READ
- LOCK
- UPDATE
- UNLOCK

Example:

```sql
-- Check current version of the product
SELECT version FROM products WHERE product_id = 1;

-- Update product price (assuming version 1)
UPDATE products
SET price = 1200.00,
    version = version + 1
WHERE product_id = 1 AND version = 1;

-- Retry if update count is zero
```

#### PROs:
- Minimal performance impact.
- Allows concurrent access.
- Suitable for infrequent conflicts.

#### CONs:
- Risk of conflicts.
- Requires conflict resolution. (retry)
- Not ideal for high contention.

#### Use Case
Optimistic locking is commonly used in scenarios where the likelihood of conflicts is low, such as:

- Content management systems where users rarely edit the same document simultaneously.
- E-commerce platforms where product prices are updated infrequently.
Day 7: Reference Wilderness
Tags: webdev, programming, javascript
Published: 2024-05-08 10:25:11

Another day, another metaphorical rabbit hole I dove down in this code labyrinth. Today's target: primitive types vs. reference types. Turns out, just like people, variables can be deceiving. You think you know someone (a variable, in this case), and BAM! They're pointing you towards something entirely different.

Primitive types are the loners, the ones who like to store their own damn data. We created a variable for the color "orange," and that's exactly what it held - the value "orange" itself. But then we went and made another variable, "fruit," and assigned it the value from "color." Here's the twist: changing the fruit didn't affect the color one bit. That's because they're each their own little island, no connection between them. Makes sense in a way, but kinda feels isolating for a variable, you know?

Then there are the arrays, the social butterflies of the variable world. Assigning an array to a variable isn't like shaking hands; it's more like handing over a map. The variable itself doesn't hold the actual array data, just a fancy pointer, a little "you-go-this-way" sign leading to where the real array lives in memory. This is why we can push new values to an array assigned with const - we're not changing the reference itself, just adding furniture to the house the pointer points to. Confusing, right? Feels like a constant shell game, gotta keep my eye on the pointer, not the variable itself.

And to top it all off, we can shove arrays inside other arrays. Like, inception for data storage. It's powerful, sure, but man, this is starting to look like a tangled mess of pointers and references. Gotta admit, the image doesn't exactly inspire confidence. Feels like I'm staring into the abyss of ever-increasing complexity.

Today was a day of cognitive overload. But hey, at least I'm learning, right? This whole reference type thing feels like a cheat code compared to primitive types, but it also comes with its own set of rules. Gotta keep that map metaphor in mind, and maybe draw some diagrams to visualize this whole mess. One step closer to understanding this digital jungle, I guess. Just gotta make sure I don't get lost in the reference wilderness.
