The Mindset of Respect in Software Engineering
Tags: programming, softwareengineering
Published: 2023-12-18 08:23:49

I respect your time that's why I try to keep this post short and write to the point. Have you seen a messy code? No comments or long unnecessary ones? Have you seen complicated names or jargon around the code base? This list can go on and on. The code that does not follow the clean code does not respect you, the author himself, and the end user! Yes, I want to emphasize the word **RESPECT**. Why we need respect who is involved and how we can implement it.

Respect is about how we create something. We care about how we and others are going to understand, use, and further enhance it. As developers or software engineers, we create. Creation is not a solitary action. As a team and company, everything is related. 

Respect is not just clean coed or following principles like SOLID and DRY. It is about how we have given it enough time and effort to think it through. John Ousterhout talks about strategic programming. He says 

> The first step towards becoming a good software designer is to realize that working code isn’t enough. It’s not acceptable to introduce unnecessary complexities in order to finish your current task faster. The most important thing is the long-term structure of the system. Most of the code in any system is written by extending the existing code base, so your most important job as a developer is to facilitate those future extensions. Thus, you should not think of “working code” as your primary goal, though of course your code must work. Your primary goal must be to produce a great design, which also happens to work. This is strategic programming.

We see respect through strategic programming rather than tactical programming which focuses on just getting something to work. 

Now from experience, we can see that we create technical dept when have no respect. Of course, it can be unintentional. But while we code we can incorporate respectfulness. This is not an easy task. Especially, when we are in a rush to fix or to finish a functionality. Management is agitated and the customer is impatient. It is a tough situation. However, in all this pressure we should remain respectful. How? We should practice it when we are in days of undisturbed tranquility. 

As a technical lead, it is you responsiblity for creating the culure of respect. Placing the stepping stones to ensure development teams understand and respect the power of creation. For example a good testing flow or code reviews can bring many issues into light. 

In conclusion, the practice of respectful engineering is not merely about writing code but encompasses a holistic approach to the development process. It involves considering the impact on oneself, fellow developers, clients, and stakeholders. Without respect, the sacrifice of code quality is inevitable. Cultivating a culture of respect in engineering and development presents a unique opportunity to create software that is not only functional but also enjoyable for everyone involved.
Codebase - The Twelve Factor App Methodology

Published: 2023-12-18 08:21:33

## One codebase tracked in revision control, many deploys

Welcome to the world of software development, where creating robust, scalable, and maintainable applications is both an art and a science. In this blog series, we'll delve into the Twelve Factors, a set of best practices designed to guide developers in building cloud-native applications. Each factor addresses a specific aspect crucial for modern software development. Let's kick off with Factor 1: Codebase.

## Codebase: The Heart of Your Application

The Codebase factor emphasizes the importance of a single codebase tracked in version control, providing a foundation for collaboration and continuous delivery. In simpler terms, it advocates for having one central place where all your application's code lives.

### Why It Matters

A unified codebase fosters consistency, making it easier for developers to work together seamlessly. It ensures that everyone is on the same page, using the same version of the code. This factor is particularly vital in the context of version control systems like Git, where changes are tracked, and collaboration becomes more manageable.

### What do we mean by "codebase"

Taking inspiration from the 12-factor website:
> A codebase is any single repo (in a centralized revision control system like Subversion), or any set of repos who share a root commit (in a decentralized revision control system like Git).

Maintaining a single codebase involves organizing your code logically and structuring your project sensibly. Adopt a version control system like Git to manage changes effectively. 

If there are multiple codebases, it’s not an app – it’s a distributed system. Each component in a distributed system is an app, and each can individually comply with twelve-factor.

Multiple apps sharing the same code is a violation of twelve-factor. The solution here is to factor shared code into libraries which can be included through the dependency manager.

### An Example

Consider a web application that tracks tasks. Instead of having different repositories for the frontend and backend, maintain a single repository for the entire application. This approach simplifies coordination and ensures that changes to both the frontend and backend are tracked together.

```
project/
  backend
  frontend
```

In conclusion, the Codebase factor sets the stage for efficient collaboration and a streamlined development process. A well-organized and version-controlled codebase is the cornerstone of successful software development.

Stay tuned for the next installment, where we'll explore Factor 2: Dependencies and delve into the intricacies of managing external libraries and dependencies in your projects.

FPGA Development Boards for Newer
Published: 2023-12-18 08:12:43

I'm constantly searching for high-quality and reasonably priced Xilinx [FPGA boards](https://www.ersaelectronics.com/c/fpgas) for beginners because my website is an FPGA resource for beginners or students. Although Xilinx FPGA boards are inexpensive and readily available, many of them are difficult for novices or students to operate since they are missing vital peripherals like switches, LCDs, RS232/VGA connectors, and 7-segment LEDs that allow new users to experiment with the board. Several Xilinx FPGA boards are too costly for novices to afford, even if they have a ton of onboard devices and are generally easy to use.
I'll talk about the greatest and most reasonably priced FPGA development boards for students or beginners nowadays. These FPGA boards are competitively priced and include everything that novices need for practice and classroom projects. 

Digilent's FPGA Development Board
An overview of the FPGA Development Board at Digilent
Arty and its development boards can be an excellent option for anyone looking for extremely adaptable and feature-rich FPGA development boards.
The Arty A7 FPGA development board for beginners is definitely pretty huge due to all the functions it contains. Its eight LEDs in all should be more than enough for most users. Though it's not the greatest, this beginner's FPGA development board is reasonably adaptable thanks to its four user switches and four user push buttons. It's great that you get a 30-day warranty in addition to its strong construction.

[Laravel] Solving Bottleneck in Laravel.
Published: 2023-12-18 08:03:28

**Intro**
- this is based on my experience in solving bottlenecks in Laravel projects hosted in AWS EC2. Most of this is simple steps that can be taken on the dot.
- this will not cover everything, but at least give you some solutions that maybe useful.

---
**Memory Bottleneck**
- Scaling your server vertically may not be the solution.
- There maybe a situation when your project running slow, but the EC2 CPU% chart is still showing below 50%. Then, it is time to check your server memory. You see, EC2 does not monitor your memory (RAM) usage by default.
- EC2 also does not 'shared' your memory to another EC2 although behind the same load balancer. i.e, a process can only be compute in one server that execute it. This is an issue if you load everything (eg: `User::all()`) into memory.
- you usually only able to check memory available by using command inside the ec2 itself:

```
cat /proc/meminfo | grep Mem
```

- Try to estimate the memory you needed and scale appropriately:

> 1 php-fpm process size: ~ 40mb - max 80mb RAM
> 1 queue worker running: ~ 140mb RAM
> Standard laravel process: ~ 2mb - 16mb RAM

---
**Database Bottleneck**
- although there is automated server auto-scaling, there is none for AWS RDS, which require manual scaling/upgrade.
- new spawn server means additional connection to your DB.
- Amount of connection a DB can handle mainly depend on the amount of RAM the DB has.
- Any RDS upgrade/scaling operations require 30 mins DB down time. Which means you cannot access your DB during this time.
- Estimate appropriately, for example a `db.t3.large (8GB)` can handle up to 600 connections
- RDS Monitoring tools can be use to monitor CPU usage, query depth and so on.
- Other steps that can be taken includes:

1. Index columns with frequent filter / querying / joining
2. Using aggregate tables (for aggregate summary) instead of query multiple tables for multiple aggregate metrics
3. Using aggregate function such as `withCount` to get directly the count instead of loading the whole relationship children. 
4. Read and write using separate database that syncing  
5. Cache common and frequent queries such as list of countries, phone codes, etc.

---
**Application Improvement**
1. Select only columns required to reduce memory consumption
2. Use eager load moderately as not everything are actually needed on the same time. Utilize lazy loading instead, where for additional information, forward user to another page (new request) instead of eager loading all at once.
3. Using raw queries instead of eloquent maybe a hassle but that depending on what information you want to fetch. Raw queries use less memory due to no need to load additional methods or properties come with eloquent
4. Utilize jobs for faster response (depend on your design) and control your application compute and memory consumption when executing something.

Bash scripts with node?
Tags: bash, node, javascript, tooling
Published: 2023-12-18 08:00:00

Good morning, everyone, and happy MonDEV! :coffee:

How was your weekend? Can you feel the Holiday spirit starting to fill the air? It's certainly strong here, and in fact, this will be the last newsletter of the year before taking a bit of a break (and preparing lots of new content for you 😉).

But before we head towards the end of the year, today, I want to introduce you to a fantastic tool that I discovered entirely by chance! Often, we find ourselves wanting to automate some of the tasks we perform more frequently or needing to programmatically execute operations that would take very shorter time to be executed from the terminal.

While we have, on one hand, the possibility to write bash scripts, it is true that more complex flows, become intricate to develop, unless you're a bash pro. On the other hand, we also have the option to perform those operations in our preferred language, but in that case, the immediacy provided by bash is often lacking.

Right in the middle of this dilemma, our tool for today steps in to help! 
Directly from our dear big G, we have [ZX](https://google.github.io/zx/). 

What is it? ZX is a wrapper that allows you to write bash scripts within .mjs files! Once installed globally, you can run the mjs files like actual bash scripts, while simultaneously leveraging the power of JS syntax we are accustomed to, such as `await` or `try-catch` blocks.

A series of APIs are also provided to interact with the entire bash environment in an extremely natural and convenient way, working on `stdin`, `stdout`, providing object-style access to arguments... in short, with ZX, you have a whole toolbox to work with bash more comfortably!

Let's quickly look at an example to see what the code looks like:
```node
import 'zx/globals';
try {
	// Create a folder and...
    await $`mkdir -p ./projects/${argv.name}`;
    
    // ...enter it to execute the next commands
    cd(`./projects/${argv.name}`);
    
	// Initialize an npm project
    await $`npm init -y`;
    
    // Create the index.js and populate it
    await $`touch index.js`;
    await $`echo "console.log('Hello, World!')" > index.js`;
    
    // Do the same for the readme
    await $`touch README.md`;
    await $`echo "# ${argv.name}" > README.md`;
    
} catch (e) {

	// In case of an error, we can handle it in JS instead of presenting the default bash error
    console.log(`Exit code: ${e.exitCode}`)
    console.log(`Error: ${e.stderr}`)
}
```

What do you think? Did you know this tool? If, like me, you are obsessed with minimizing repetitive work, I'm sure you should take a look 😉

With this gem, the newsletter takes a break for the Christmas holidays! I wish you a good start to the week, happy holidays, and a great start to the new year! We'll catch up on January 8th!

As always, Happy Coding 0_1

Website speed is crucial for user experience and SEO ranking. This blog post explores how web hosting can impact website speed and offers solutions for improvement.

### How Hosting Affects Website Speed

1. **Slow Server**: A slow server translates to a slow website, frustrating users. Outdated technology and unpatched servers worsen performance.

2. **Limited Resources**: Bandwidth and data transfer limitations can cause slowdowns during traffic spikes.

3. **Server Location**: Distant servers lead to longer response times for users. Choose a hosting provider with servers near your target audience.

4. **Security Concerns**: Weak security measures leave websites vulnerable to attacks, impacting performance during cleanup.

5. **Poor Support**: Slow response times from hosting providers can delay website maintenance and updates.

### Signs of Slow Hosting

1. **Slow Loading Times**: The most obvious sign of bad hosting is a slow website.

2. **Traffic Spikes**: Inability to handle sudden traffic surges can lead to crashes and performance drops.

### Solutions for Improving Website Speed

1. **Upgrade Hosting Plan**: Consider a VPS or dedicated server plan for increased resources and improved performance.
2. **Content Delivery Networks (CDNs)**: CDNs store website copies across geographically distributed servers, delivering content to users from the closest location.
3. **Optimize Website Content**: Compress images and minify code (CSS, JavaScript, HTML) to reduce file sizes and improve loading times.
4. **Website Speed Testing**: Regularly test website speed to identify bottlenecks like large files or inefficient code.
5. **SEO Benefits**: Faster websites rank higher in search engine results pages (SERPs).

### Conclusion

Choosing the right hosting provider is essential for website speed. By addressing hosting-related issues and implementing solutions like CDNs and content optimization, you can create a fast, user-friendly website that ranks well in search engines.
