Intro:
I first became aware of a company website as important strategic tool when I took a marketing course, for big corporations like construction firms. One of the ideas that struck me with inspiration was over-comming my fear to build a static website, an actual one this time - for Toucsan:-). The initially very scary prospect of really turned into something where I learned so much in the months following doing it, that after all is said and done my taste for web development was greatly heightened.
The Process:
The process started with ideation - researching everything about Toucsan, their industry and customer base. Afterwards, I began exploring the technical and necessary technologies in order to make my vision reality. The mockup design was an essential step during which I could layout the structure and visual styles before being on the coding phase.
The real test of its capabilities came with the actual build. Inspired by the "step-by-step tutorials" that make VLC app-making seem like a piece of cake, I still decided to give it another shot. I losttrack of how many times I got frustrated styling, structuring and integrating features. But as I cleared each hurdle, my confidence and ablilities expanded.
One of the biggest challenges was ensuring the website was mobile-friendly. Implementing responsive design using media queries was a whole new skill set I had to develop. But seeing the site adapt seamlessly to different screen sizes was incredibly rewarding.
Reflections:
While the final product may not have been perfect, I'm proud of what I accomplished. This first static website build was an invaluable learning experience. I now have a deeper understanding of web development fundamentals, from front-end architecture to user experience design.
Most importantly, this project has inspired me to keep building. The sense of accomplishment I felt upon completing Toucsan's website has fueled my passion for coding. I'm excited to take on more projects and continue honing my skills as a web developer.
Conclusion:
Building my first static website for Toucsan Construction was a formative experience that has left a lasting impact. What began as an ambitious goal became an empowering journey of learning, problem-solving, and personal growth. I'm grateful for the lessons learned and the motivation to keep evolving as a web developer. | mai2aa |
1,919,052 | Picking up coding after a long hiatus | 10 print “David is great! ”; 20 goto 10 run Enter fullscreen mode Exit fullscreen... | 0 | 2024-07-10T23:13:32 | https://dev.to/dave_banwell_26fd6e4680c0/picking-up-coding-after-a-long-hiatus-1dmb | webdev, javascript, learning, career | ```
10 print “David is great! ”;
20 goto 10
run
```
That momentous 2-line program and simple command were the first things that I ever typed into a computer, in 1980. My grandmother had borrowed a Commodore PET computer for the summer, from the school where she taught and, over that summer, my aunts taught 5-year-old me the _basics_ of coding in… well… BASIC. They couldn't have known, at the time, that they were laying the foundation for a lifelong obsession with logic, analysis, and problem solving.
In grades 7 and 8, I learned even more about BASIC in a formal setting: variables and variable types, loops, decisions, etc. And, by this time I had my own home computer for practice. I always felt excited when being presented with a new challenge to solve through this cutting-edge technology. In high school, we learned to program simple games, like hangman and craps. It seemed like nothing was impossible with this one, simple language.
In university, I learned HTML and later taught myself CSS (version 2). I loved building simple websites for people and even made some money doing it on the side. But technology started to broaden and advance and – with a full-time job with an insurance company – I didn’t really have the time to upgrade my skillset and I left programming behind.
About 20 years into my career at the same insurance company, I ran into a real problem: I was the sole keeper and maintainer of a large and very important dataset. I was going on vacation for more than a month and there was no one else who could run the weekly updates. My boss tasked me with training someone, but there wasn’t enough time. Knowing the process, I went to Google for a solution and, voila… VBA.
The more that I used VBA in my role as a reporting analyst, the more I grew to depend on it. Not only did it give me a far greater skillset in terms of data mining, but it enabled me to do my job a LOT faster. I’d find myself getting lost in code and loving it. I needed more of this in my life!
And, so, here I am at the end of Phase 1 of Flatiron School’s software engineering bootcamp! I am so completely in love with this program, and I’ve only begun to scratch the surface. With such a long gap in my coding experience, I’m just amazed at a couple of things:
1. How much has stayed the same
2. How much has changed
I’m blown away that many of the basic concepts that comprise JavaScript are identical to those underpinning BASIC from 40+ years ago. Learning a brand new language seemed so daunting at first. But, from day 1, it was like riding a bicycle. It was certainly a newer bike with a heaps more features, but it did the same basic things and was incredibly simple to grasp.
My experience with HTML and CSS was somewhat similar. I had a great deal of familiarity with them 20 years ago and relearning them was a snap! But, as much as the fundamentals have remained the same, there are some major and hugely beneficial differences.
When I originally learned web programming, we coded everything in HTML, from the text to the formatting, to the positioning of elements (anyone remember frames?). Dynamic content was virtually unheard of. CSS was emerging, but its main focus was formatting text elements. If you wanted animations, you had a choice between the <marquee> tag or learning Macromedia Flash. Still, HTML did all the heavy lifting.
I was shocked in the best of ways to see the even, three-way distribution of duties among HTML, CSS, and JavaScript, today. With HTML handling text and text structure, CSS handling all formatting and positioning, and JavaScript working its magic on each of them to produce dynamic content, not to mention interacting with servers and enabling some basic data processing, it seems like anything is possible. And we’ve only _just_ scratched the surface.
My greatest surprise has been just how much functionality is baked into CSS. The sheer volume of properties and values that one can apply to elements and classes is staggering to someone who had only used it for font colours and sizes, previously. I’m thrilled to have so many new tools in my toolbox and I am challenged to use them judiciously.
I remain as excited, today, at running an application of my own making as I had been as a 5-year-old, pressing the <enter> key to run that small, but mighty, program at the top of this post. And I know – and relish the thought – that I still have so much to learn.
I have two pieces of advice for anyone who's considering picking up coding again, after a long hiatus:
1. It is truly never too late.
2. It's not nearly as daunting as it might seem.
Happy coding!

1,919,054 | Boost Your Development Efficiency! Simulate S3 with a Custom Amazon S3 Mock Application | 💡Original japanese post is here. https://zenn.dev/tttol/articles/13032ef69d8333 ... | 0 | 2024-07-10T23:23:16 | https://dev.to/aws-builders/boost-your-development-efficiency-simulate-s3-with-a-custom-amazon-s3-mock-application-19ah | > 💡Original japanese post is here.
> https://zenn.dev/tttol/articles/13032ef69d8333
## Introduction
I've developed a mock application for Amazon S3 called "MOS3" (pronounced "mɒsˈθri"). Similar to [LocalStack](https://www.localstack.cloud/), MOS3 is an S3-like application that runs in a local environment.
MOS3 is a GUI application that allows you to manage files directly from your browser. You can upload files without having to use CLI commands like `aws s3 cp`.
Moreover, MOS3 can handle S3 requests from the AWS SDK, making it possible to simulate S3 operations locally.
You can find the source code here:
https://github.com/tttol/mos3
## Background
I am an application engineer, and I frequently develop web applications using Java and other technologies.
Many of the applications I create use S3 as external storage, and it's often necessary to connect to S3 even for local development. While I sometimes use a development AWS account with actual S3 buckets, setting up an account can be cumbersome for small-scale applications. In such cases, I've used LocalStack as a mock for S3.
LocalStack is an excellent and convenient open-source software, but I have noticed some challenges:
- It's primarily operated via CLI, making GUI-based file management difficult.
- There is a GUI feature, but it didn't meet my requirements.
- LocalStack provides resources beyond S3, but I rarely need anything other than S3, making it overly complex for my needs.
Given these challenges, I thought, "Why not create something that perfectly fits my needs?" And thus, MOS3 was born.
## Features
### Use as a Local Replacement for S3
MOS3 runs at http://localhost:33333/s3.
※ For detailed installation instructions, please refer to the [README](https://github.com/tttol/mos3?tab=readme-ov-file#install).
MOS3 can be used as a standalone S3-like local file server, but it also accepts requests from the AWS SDK. For example, if you send a request using the [getObjects](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/s3/AmazonS3Client.html#getObject-com.amazonaws.services.s3.model.GetObjectRequest-) method from the AWS SDK for Java, MOS3 will respond with the specified key's object.
To call MOS3 from the AWS SDK for Java, you need to set the endpoint of the `S3Client` to http://localhost:3333. Here’s a code sample:
```java
S3Client s3 = S3Client.builder()
.region(region)
.endpointOverride(new URI("http://localhost:3333"))
.build();
```
#### Caution
When specifying localhost as the endpoint, you may need to enable path-style access for it to work correctly.
```java
S3Configuration s3Configuration = S3Configuration.builder()
.pathStyleAccessEnabled(true) // enable path style access
.build();
S3Client s3 = S3Client.builder()
.region(region)
.endpointOverride(new URI("http://localhost:3333"))
.serviceConfiguration(s3Configuration)
.build();
```
### File Management via Browser
MOS3 allows you to manage files and directories through your browser.
You can upload files by clicking the "New File" button.
You can create new directories by clicking the "New Dir" button.
You can download files by clicking on them.
You can delete files or directories by clicking the trash can icon on the right.
### Linking with Your Local PC Directory
```bash
docker run -p 3333:3333 -v ./upload:/app/upload -it --rm tttol/mos3:latest
```
The above is the command to run MOS3. (Quoted from the [README](https://github.com/tttol/mos3?tab=readme-ov-file#install))
MOS3 runs on a Docker container.
The key point here is the use of the -v option to mount the volume. Files uploaded to MOS3 are internally stored in the `/app/upload` directory. By mounting it with `-v ./upload:/app/upload` during container startup, files on MOS3 are synchronized with the `./upload` directory. Therefore, you can manage MOS3 files directly from Mac Finder or Windows Explorer.
## Future Features
MOS3 is still a work in progress. Below are some of the features I plan to implement in the future.
### Handling Requests from AWS SDKs Other Than Java
I often use Java, so I have mainly implemented support for requests from the AWS SDK for Java. However, the behavior with other SDKs is not guaranteed, as some work and others do not. I plan to extend support to other SDKs in the future, but this remains a future task.
### Handling AWS CLI Requests
Handling AWS CLI requests for commands like ls, mb, cp, and rm is still a work in progress. While ls and cp are minimally supported, handling other commands is a future task.
## Conclusion
MOS3 is open-source software (MIT License). Issues and pull requests are welcome.
I will continue to improve MOS3 to make it an even more user-friendly application.

1,919,072 | Priscilla Haruna_Assignment 2 part2 | Today's digital world has made cloud computing a basic component of modern technology, changing both... | 0 | 2024-07-10T23:56:28 | https://dev.to/priscilla_haruna_ee515f75/priscilla-harunaassignment-2-part2-3dh6 | cloudcomputing, devops, cloud, beginners | Today's digital world has made cloud computing a basic component of modern technology, changing both how individuals and corporations handle their digital lives.
What is Cloud Computing?
Cloud computing refers to the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the internet (“the cloud”). This allows for faster innovation, flexible resources, and economies of scale. Instead of owning their own computing infrastructure or data centers, companies can rent access to anything from applications to storage from a cloud service provider.
Benefits of Cloud Computing
1. Cost Efficiency One of the most significant benefits of cloud computing is cost savings. It eliminates the capital expense of buying hardware and software and setting up and running on-site data centers. Additionally, the pay-as-you-go pricing model means you only pay for what you use, which can lead to significant savings.
2. Scalability Cloud computing provides the ability to scale resources up or down as needed. This means you can easily handle increased workloads or expand your services without investing in new infrastructure.
3. Performance Major cloud services run on a worldwide network of secure data centers, which are regularly upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a single corporate data center, including reduced network latency and higher economies of scale.
4. Speed and Agility With cloud computing, vast amounts of computing resources can be provisioned in minutes, giving businesses a lot of flexibility and taking the pressure off capacity planning. This agility can give businesses a significant competitive advantage.
5. Reliability Cloud computing makes data backup, disaster recovery, and business continuity easier and less expensive because data can be mirrored at multiple redundant sites on the cloud provider’s network.
Cloud Deployment Models
There are several ways to deploy cloud services, each catering to different business needs. The primary cloud deployment models include:
1. Public Cloud The public cloud is owned and operated by third-party cloud service providers, which deliver their computing resources like servers and storage over the Internet. All hardware, software, and other supporting infrastructure are owned and managed by the cloud provider.
2. Private Cloud A private cloud refers to cloud computing resources used exclusively by a single business or organization. A private cloud can be physically located on the company’s on-site datacenter, or it can be hosted by a third-party service provider. The services and infrastructure are maintained on a private network.
3. Hybrid Cloud A hybrid cloud is a combination of public and private clouds, bound together by technology that allows data and applications to be shared between them. By allowing data and applications to move between private and public clouds, a hybrid cloud gives businesses greater flexibility and more deployment options.
Cloud Service Models
Cloud computing services are typically offered in three primary models, each providing a different level of control, flexibility, and management:
1. Infrastructure as a Service (IaaS) IaaS is the most basic cloud service model, offering essential compute, storage, and networking resources on demand, on a pay-as-you-go basis. IaaS gives users the highest level of flexibility and management control over their IT resources.
2. Platform as a Service (PaaS) PaaS provides a platform allowing customers to develop, run, and manage applications without dealing with the infrastructure. This helps developers focus on the software development process without worrying about the underlying hardware and software layers.
3. Software as a Service (SaaS) SaaS is a way of delivering
software applications over the internet, on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure and handle any maintenance, like software upgrades and security patching.
In conclusion, cloud computing is transforming the IT landscape by providing individuals and businesses with powerful tools and resources that were once out of reach. With its cost efficiency, scalability, performance, speed, and reliability, it stands as an attractive solution for modern computing needs. By understanding the different deployment and service models, organizations can tailor their cloud strategies to meet their unique needs, fostering innovation and growth. | priscilla_haruna_ee515f75 |

1,919,074 | Difference between MySQL and PostgreSQL | Choosing the right database system can be tricky, especially when comparing two popular options like... | 0 | 2024-07-11T00:03:01 | https://dev.to/squad_team_986b85db08e8d2/difference-between-mysql-and-postgresql-40b | sql, mariadb, database, tutorial | Choosing the right database system can be tricky, especially when comparing two popular options like MySQL and PostgreSQL. Both have their own strengths and features that make them suitable for different needs. This article will help you understand the differences and make an informed choice.
**Key Takeaways**
MySQL and PostgreSQL have different origins and histories, which influence their development paths.
Licensing and cost can vary significantly between the two, with different open-source and commercial options.
Performance and optimization techniques differ, affecting how each handles queries and data indexing.
Both databases support a variety of data types and extensions, but with unique features.
Security features, backup and recovery options, and community support are also key areas where MySQL and PostgreSQL differ.
Historical Development and Evolution
**Origins of MySQL**
MySQL was created in the mid-1990s by a Swedish company called MySQL AB. It was designed to be a fast, reliable, and easy-to-use database management system. Over the years, MySQL has become one of the most popular databases in the world, especially for web applications.
**Origins of PostgreSQL**
PostgreSQL, on the other hand, has its roots in the 1980s. It started as a project at the University of California, Berkeley, known as POSTGRES. The goal was to create a more advanced database system that could handle complex queries and large amounts of data. PostgreSQL has evolved significantly since then, becoming a powerful and versatile database system.
**Key Milestones in Development**
Both MySQL and PostgreSQL have seen numerous key milestones in their development. For MySQL, one of the most significant was its acquisition by Sun Microsystems in 2008, and later by Oracle Corporation in 2010. This brought more resources and development power to the platform.
For PostgreSQL, a major milestone was the release of version 7.0 in 2000, which included support for SQL92 and SQL99 standards. This made PostgreSQL a more competitive option for enterprise applications.
Understanding the historical context of these databases helps us appreciate their current capabilities and future potential. Both MySQL and PostgreSQL have rich histories that contribute to their robustness and reliability today.
**Licensing and Cost**
Open Source Nature
Both MySQL and PostgreSQL are open-source databases, meaning they are free to use and modify. This [open-source](https://sqlskillz.com/course/mini-course-sql-query-expansion) nature allows for a high degree of flexibility and customization, which can be particularly beneficial for organizations with specific needs. However, the open-source model also means that users are responsible for their own support and maintenance.
**Commercial Support Options**
While both databases are free, they offer commercial support options. For MySQL, Oracle provides various support packages that include advanced features and professional assistance. PostgreSQL, on the other hand, has a more community-driven support model but also offers commercial support through various third-party vendors. This can be crucial for businesses that require reliable and timely support.
**Cost Implications**
The cost implications of using MySQL or PostgreSQL can vary. Since both are open-source, the initial cost is zero. However, the total cost of ownership can include expenses for commercial support, hardware, and additional software. Organizations must carefully evaluate their needs and budget to make an informed decision.
Choosing between MySQL and PostgreSQL often comes down to specific business requirements and the level of support needed. While both offer robust features, the choice may hinge on factors like community support, commercial options, and overall cost.
**Performance and Optimization**
Query Performance
When it comes to query performance, both MySQL and PostgreSQL have their strengths. MySQL is often praised for its speed in read-heavy operations, making it a popular choice for web applications. PostgreSQL, on the other hand, excels in complex queries and large datasets due to its advanced query planner and optimizer. Choosing the right database often depends on the specific needs of your application.
**Indexing Techniques**
Indexing is crucial for database performance. MySQL supports various indexing methods like B-tree, hash, and full-text indexes. PostgreSQL also offers a wide range of indexing options, including B-tree, hash, GiST, SP-GiST, GIN, and BRIN indexes. The flexibility in PostgreSQL's indexing can be particularly beneficial for specialized queries.
**
Optimization Tools**
Both databases come with a set of tools to help with optimization. MySQL offers tools like EXPLAIN, which helps in understanding how queries are executed. PostgreSQL provides similar tools, such as EXPLAIN ANALYZE, which offers more detailed insights. Additionally, PostgreSQL has built-in support for performance monitoring and tuning through extensions like pg_stat_statements and auto_explain.
In summary, while both MySQL and PostgreSQL offer robust performance and optimization features, the choice between them should be guided by the specific requirements of your project.
**Data Types and Extensions**
**Supported Data Types**
When comparing MySQL and PostgreSQL, one of the first things we notice is the variety of data types each supports. MySQL offers a range of basic data types like integers, floats, and strings. PostgreSQL, on the other hand, provides a more extensive list, including support for arrays, hstore, and JSONB. This makes PostgreSQL particularly versatile for complex applications.
**Custom Data Types**
Both databases allow for the creation of custom data types, but PostgreSQL excels in this area. With PostgreSQL, we can define composite types, range types, and even custom domains. This flexibility is crucial for applications requiring specialized data handling.
**Extensions and Plugins**
PostgreSQL stands out with its rich ecosystem of extensions and plugins. From PostGIS for spatial data to full-text search capabilities, PostgreSQL's extensions significantly enhance its functionality. MySQL also offers plugins, but they are generally less diverse and less integrated into the core system.
The ability to extend database functionality through plugins and extensions is a key factor in choosing between MySQL and PostgreSQL. PostgreSQL's extensive library of extensions makes it a strong candidate for projects needing advanced features.
**Security Features**
**Authentication Mechanisms**
In both MySQL and PostgreSQL, authentication is a critical aspect. MySQL supports various authentication methods, including native password, SHA-256, and LDAP. PostgreSQL, on the other hand, offers more flexibility with methods like MD5, SCRAM-SHA-256, and GSSAPI. Choosing the right authentication method is essential for securing database access.

I've forgotten when it was released, but at some point in the past, I released an app called [Bill Panda](https://sunnyorlando.dev/billpanda), which you can read about following the link. It was my first complete app that I built to solve a personal problem. I went through the full experience of building it, tearing it down, rebuilding it, tearing it down again, and building it again. I created an LLC that the app is published under, a business banking account, and a light website to market the app. This is a post reflecting on some things I learned during this experience.
## Why I built it in the first place
For a long time I was using a spreadsheet to manage my recurring bills. There were apps out there, like Mint, that automate some of this stuff for you. But I always disliked that I couldn't mark my bills as paid ahead of time. I also couldn't use the data to create any cash projections. So i thought, why not build my own? It needed to do a few simple things:
1. Track my recurring bills.
2. Notify me of upcoming bills.
3. Allow me to mark them as paid/unpaid.
4. Let me add notes
5. And eventually, reporting, so I can make cash projections.
I originally built it using Laravel - a web application framework. The frontend was all in Vue and the backend was PHP. You can see a demo of it here (I demoed it for a Hackathon, which I won second place :D): [Bill Panda Web](https://devpost.com/software/family-newsletter.). The second time I used React Native. The third and final time, it was all Swift UI. It's been a fun journey building the app. I'm finally at a point where I can begin thinking about new features for it. But before I get to those, I thought I'd share a few mistakes I made along the way. You may find this helpful if:
1. You are about to build a payment system with recurrence.
2. You work with recurring events in general.
3. You plan on building your own app.
## Mistakes
### 1. Regarding Recurring Events - Don't store every occurrence in your database!
When I built the web-based version, i made a critical mistake. For my use-case, you should never populate your database with all occurrences of a recurring event. Not only are you creating a TON of data, you also corner yourself by having to answer questions like "this event repeats daily until the end of time, do i create every single event until the end of time in my database? Do i cap it to the first 1,000 events?” Whats the right number of recurring events to create? There is no right number.
During my research developing recurring events, I ran into this amazing post on Github by user bmoeskau: https://github.com/bmoeskau/Extensible/blob/master/recurrence-overview.md. This post sent me in the right direction. You do not create every occurrence, you compute them. You follow a recurrence rule standard that's been around since [1998](https://en.wikipedia.org/wiki/ICalendar). I highly suggest reading the github post I linked above if you are going to create a recurring event system!
### 2. Your friends and family may not like to use your app if they know that you have access to their finances
If you've built the application, you have access to the database. You can promise you'll never look at the database, but cmon, you probably will. Trust is a big thing when it comes to finances - your friends and family probably won't want to use your app if it means handing over all their data. You have to **guarantee** that their data will not be accessible to you. During the time that I developed the web app, I did not have a way around this. But by pivoting the technology I used, I did find a way.
At some point in the last couple of years, Apple announced SwiftUI.
This looked so interesting that I ended up diving back into iOS development (I've jumped back and forth between iOS/Android app development and Web Development in my history). As I started working in SwiftUI, I thought, why not try CoreData one more time? Maybe work with CoreData and CloudKit. If i was to incorporate CloudKit, the user never has to sign into the app. All their data can live inside a private CloudKit container that I, as the developer, have ZERO access to. It also has an incredible generous free tier that makes it so that I don't have to pay anything. Furthermore, CloudKit data syncs across your iOS devices seamlessly. It had everything I needed (it was also a huge, painful, learning curve). Happy to say that I made the right decision :). The app is running fully on CloudKit.
### 3. Not working with technology you love
If you have a hobby project and your goal isn't really to get rich, then don't work with technology you loath. This is not to say that I hate Laravel or Vue (they powered the first iteration) - I truly love those technologies. No, the one i tend to loath sometimes is React Native -- which I used for the second iteration of the app.
If you look at a prior post of mine (https://dev.to/m4rcoperuano/react-native-best-practices-when-using-flatlist-or-sectionlist-4j41), I wrote:
> ...React Native has been the only [language]that has been able to change my mind and has me questioning why I would ever want to code in Swift or Java again.
Looking back, this is still true.....sometimes. Sometimes I hate it. The debugging (not knowing if the bug is in your javascript code, your native module, the react native run time, or once its packaged) is maddening. This doesn't mean I would never code with React Native. For example, if you want to make a cross-platform app, or if it's a requirement from your client/job, then its no problem. But if you're doing it for fun, and you don't care about cross-platform, then save yourself the headache. Work with the native code and framework.
But I digress. If you are working on a hobby project, work with tech that you love. It will motivate you to keep going back to it. Personally, I love using SwiftUI and sometimes wish it was all I did.
## Sidequest: Why Is SwiftUI Awesome?
SwiftUI is pretty darn cool once you get the hang of it. This is a framework that Apple has developed so that its easier to make native iOS apps. Here's a quick example:
```swift
struct MonthHeader: View {
var monthName: String;
var totalDue: Int;
var amountPaid: Int;
var body: some View {
VStack(alignment:.leading, spacing: 2) {
Text(monthName)
.font(.headline)
.foregroundColor(Color.textGeneral)
HStack {
Text("\(amountPaid.toCurrency) paid ")
.foregroundColor(Color.brand)
.font(.subheadline.bold())
+
Text("out of \(totalDue.toCurrency)")
Spacer()
}
}
.padding()
.background(.thinMaterial)
.listRowInsets(EdgeInsets(
top: 0,
leading: 0,
bottom: 0,
trailing: 0))
}
}
```
This is a pretty simple view that displays this:
I find this code super readable. You have:
- 3 required parameters defined at the very top. These are your "props", essentially (if you are familiar with Vue or React)
```swift
struct MonthHeader: View {
var monthName: String;
var totalDue: Int;
var amountPaid: Int;
....
```
- You then have you "body" field, which is essentially a `template` tag, or what you return from a React component (again, if you are familiar with web). You can learn what the code does by reading my comments below:
```swift
var body: some View {
//VStack stands for Vertical Stack
VStack(alignment:.leading, spacing: 2) {
//Inside it we have a Text field that displays your prop,
// monthName. It's then modified to look like a headline
// with a specific foregroundColor.
Text(monthName)
.font(.headline)
.foregroundColor(Color.textGeneral)
//Then you have an HStack, or Horizontal Stack, that takes
// your prop amountPaid and uses an extension (a function)
// that converts it to currency. It also sets the color to a
// specific "brand" color that I selected, and makes the
// font a subheadline that is bolded.
//Finally, another text element is right next to it
// (concatenated) that represents the amount due. The reason
// is separated from the first Text element is because I
// don't want it to be colored at all.
HStack {
Text("\(amountPaid.toCurrency) paid ")
.foregroundColor(Color.brand)
.font(.subheadline.bold())
+
Text("out of \(totalDue.toCurrency)")
Spacer()
}
}
//Then i apply some padding, change its background color to a
// .thinMaterial, which apple has provided -- it changes the
// background color to be blurred and translucent
.padding()
.background(.thinMaterial)
//finally, i remove any default padding provided by default
// from Apple's SwiftUI framework
.listRowInsets(EdgeInsets(
top: 0,
leading: 0,
bottom: 0,
trailing: 0))
}
```
Compared to the past, where you would have to create Swift ViewControllers, or worse, Objective-C ViewControllers, this is much welcome change. If my job was to create Swift apps full time, man, that would be exciting.
## Summary
It took about 3 years to get the app to a state where I was happy with it. The app was built during nights and weekends, sometimes on vacations. It, thankfully, wasn't too stressful to build. If you love to code and you have a goal in mind, then you'll find the time to make the app that you always wanted to make. Its okay if it takes a long time--we have day jobs. Will I ever make money on this app? I don't really know and I don't really think about it. It serves its purpose to me and a few others (I have about 40+ daily users!). That's all I need to be content with it :).

> `Disclaimer`: I won't create expectations with my posts. Everything I share is part of my learning process, which often involves explaining things to others. I found this method to be particularly effective during my time at [42 School](https://www.42network.org/). Therefore, I'll be posting about various topics I'm currently learning or have already learned.
---
# Why this post?
I'm actually doing a challenge for a job vacancy and I was struggling with _`shared objects`_ and I'm doing it in my home, so I remember who hard are don't have another person near you to ask things even if they don't know the answer, they help you to think and find new ways or they have new ideas or even better, they help you to have new ideas and so forth.
---
## First step
This challenge involves creating a shared library in any programming language of my choice.
The library will be tested with a specifically crafted binary file written in `C`. My goal is to ensure the library functions as intended based on the provided test outputs.
---
## Working on it
During a recent interview, I was presented with a challenge: create a shared library that functions as a *CSV processor*. Initially, I opted to develop it in Go. It seemed like a straightforward task...
While writing the Go code itself wasn't an issue, the real challenge arose in integrating the library with the `C` binary. Every attempt resulted in different errors, often related to missing symbols in the generated shared object _(.so file)_.
Fortunately, I eventually found a solution and was able to test the library using the provided binary. However, running the program resulted in a core dump, indicating unexpected behavior.
To address this issue, I opted to switch to C++. The primary reason was the perceived ease of interfacing shared objects created in `C++` with `C` binaries. This approach minimized debugging difficulties and eliminated core dumps.
---
## Final Thoughts
Despite the initial hurdles, I'm still tackling the `CSV processor` challenge in `C++`. Having a better understanding of shared objects and dynamic linking ~~(thanks to my previous experience with static libraries)~~ is definitely helpful. However, the initial issues I encountered took a significant amount of time to resolve.
Cya!

1,919,078 | Day 10 of my 90 Days Devops- Kubernetes Networking Fundamentals | Introduction Welcome to Day 10 of my SRE and Cloud Security Journey! Today, I delved into... | 0 | 2024-07-11T00:41:22 | https://dev.to/arbythecoder/day-10-of-my-90-days-devops-kubernetes-networking-fundamentals-50fa | network, devops, kubernetes, beginners | ## Introduction
Welcome to Day 10 of my SRE and Cloud Security Journey! Today, I delved into the fascinating world of Kubernetes networking. If you're a DevOps engineer with some experience, but new to Kubernetes networking, this guide is for you. We'll explore how Kubernetes handles networking, including Services, Endpoints, DNS, and the essential role of `kube-proxy`.
### Why Kubernetes Networking Matters
In a Kubernetes cluster, the way Pods communicate with each other and with the outside world is crucial. Proper networking ensures that your applications are reliable, scalable, and secure. Understanding these fundamentals will not only make you proficient in managing Kubernetes clusters but also enable you to troubleshoot and optimize your deployments more effectively.
## Key Concepts in Kubernetes Networking
### 1. Services
Services are a fundamental concept in Kubernetes that abstract a set of Pods and provide a stable endpoint for them. This is crucial because Pods are ephemeral and can be created and destroyed frequently.
#### Types of Services
- **ClusterIP (default):** This type of Service exposes the application within the cluster using an internal IP. It's perfect for internal communication between Pods.
```yaml
apiVersion: v1
kind: Service
metadata:
name: my-internal-service
spec:
selector:
app: MyApp
ports:
- protocol: TCP
port: 80
targetPort: 9376
```
- **NodePort:** This Service type exposes the application on a static port on each node's IP. It's useful for accessing the application from outside the cluster.
```yaml
apiVersion: v1
kind: Service
metadata:
name: my-nodeport-service
spec:
type: NodePort
selector:
app: MyApp
ports:
- protocol: TCP
port: 80
targetPort: 9376
nodePort: 30007
```
- **LoadBalancer:** This type integrates with cloud providers to create an external load balancer, which routes external traffic to the Service. It's ideal for exposing services to the internet.
```yaml
apiVersion: v1
kind: Service
metadata:
name: my-loadbalancer-service
spec:
type: LoadBalancer
selector:
app: MyApp
ports:
- protocol: TCP
port: 80
targetPort: 9376
```
- **ExternalName:** This Service type maps a Service to a DNS name, allowing Kubernetes to proxy traffic to an external service.
```yaml
apiVersion: v1
kind: Service
metadata:
name: my-external-service
spec:
type: ExternalName
externalName: example.com
```
### 2. Endpoints
Endpoints are Kubernetes objects that store IP addresses of the Pods matched by a Service selector. They are dynamically updated as Pods are created or destroyed, maintaining the association between Services and the actual IP addresses of Pods.
#### Example
When you create a Service, Kubernetes automatically creates an Endpoints object:
```yaml
apiVersion: v1
kind: Endpoints
metadata:
name: my-service
subsets:
- addresses:
- ip: 192.168.1.1
- ip: 192.168.1.2
ports:
- port: 9376
```
### 3. DNS
Kubernetes includes a built-in DNS service that automatically creates DNS records for Services. This enables you to access Services using DNS names, making it easier to manage and connect your applications.
#### Example
For a Service named `my-service` in the `default` namespace, Kubernetes creates a DNS entry `my-service.default.svc.cluster.local`. Pods within the same namespace can access the Service simply by using `my-service`.
### The Role of kube-proxy
`kube-proxy` is a critical component in Kubernetes networking. It runs on each node and is responsible for maintaining network rules. Here's how it works:
1. **Monitoring:** `kube-proxy` watches the Kubernetes API for changes to Services and Endpoints.
2. **Updating Rules:** It updates the network rules on the node to ensure traffic is correctly routed.
3. **Load Balancing:** `kube-proxy` implements load balancing for Service traffic, distributing requests among the available Pods.
#### How kube-proxy Manages Network Rules
`kube-proxy` can manage network rules in three modes:
- **Userspace:** This is the oldest mode and the least efficient. It proxies traffic through a userspace process, which can be a bottleneck.
- **iptables:** A more efficient mode that uses `iptables` rules to direct traffic. It's fast and has low overhead.
- **IPVS:** The most efficient mode, using Linux IP Virtual Server (IPVS) to handle traffic. It offers better performance and scalability.
## Conclusion
Understanding Kubernetes networking is a pivotal skill for any DevOps engineer working with Kubernetes. By mastering Services, Endpoints, DNS, and the role of `kube-proxy`, you'll be well-equipped to manage and secure your Kubernetes applications. As I continue my journey, I’ll dive deeper into these concepts and explore practical applications to enhance the security and reliability of my deployments.
Stay tuned for tomorrow's hands-on project where I’ll apply these networking fundamentals to improve network security in a Kubernetes cluster. If you have any questions or insights, feel free to reach out!

1,919,087 | Understanding Cloud Computing: A Beginner's Guide | In today's digital age, businesses and individuals alike are increasingly turning to cloud computing... | 0 | 2024-07-11T00:37:10 | https://dev.to/richard_bonney_eb884870a1/understanding-cloud-computing-a-beginners-guide-48dm | In today's digital age, businesses and individuals alike are increasingly turning to cloud computing to meet their computing needs. But what exactly is cloud computing, and what makes it so beneficial? Let's explore the basics, its advantages, and the different models it offers.
What is Cloud Computing?
At its core, cloud computing is the delivery of various services over the Internet. These services include storage, databases, servers, networking, software, and more. Instead of owning physical hardware and software, users access these resources remotely, typically through a service provider. This means that data and applications are stored on remote servers, or "the cloud," and can be accessed from anywhere with an Internet connection.
Benefits of Cloud Computing
Cloud computing offers several significant advantages:
1. Cost Savings: One of the most compelling benefits is the reduction in capital expenses. Businesses no longer need to invest heavily in physical hardware and maintenance.
2. Scalability: Cloud services are highly scalable, meaning businesses can easily adjust their computing resources based on demand. This flexibility ensures that companies can handle peak loads without investing in extra infrastructure that sits idle during off-peak times.
3. Accessibility: With cloud computing, data and applications are accessible from any location with an internet connection. This supports remote work and collaboration, as employees can access the tools they need from anywhere in the world.
4. Disaster Recovery: Cloud providers often include robust disaster recovery options, ensuring that data is backed up and recoverable in case of an emergency. This can be more cost-effective and reliable than traditional disaster recovery solutions.
5. Automatic Updates: Cloud services typically include automatic updates and patches, which means users always have access to the latest features and security enhancements without having to manage these updates themselves.
Cloud Deployment Models
Cloud computing can be deployed in three ways, each offering different levels of control, flexibility, and management:
1. Public Cloud: In this model, services are delivered over the public Internet and shared across multiple organizations. Public cloud providers, like Amazon Web Services (AWS) or Microsoft Azure, offer a range of services and resources on a pay-per-use basis.
2. Private Cloud: A private cloud is dedicated to a single organization. It can be hosted on-premises or by a third-party provider. Private clouds offer greater control and security, making them suitable for businesses with specific compliance or security needs.
3. Hybrid Cloud: Combining both public and private clouds, a hybrid cloud allows data and applications to be shared between them. This model offers the flexibility of the public cloud with the security and control of a private cloud.
Cloud Service Models
Cloud computing services are typically categorized into three primary models:
1. Infrastructure as a Service (IaaS): This model provides virtualized computing resources over the Internet. IaaS offers the most control over computing resources and is ideal for businesses needing flexibility to build and manage their applications. Examples include Amazon EC2 and Google Compute Engine.
2. Platform as a Service (PaaS): PaaS delivers hardware and software tools over the Internet, typically used for application development. It allows developers to build applications without worrying about the underlying infrastructure. Examples include Google App Engine and Microsoft Azure App Service.
3. Software as a Service (SaaS): SaaS delivers software applications over the Internet on a subscription basis. These applications are managed by a third-party provider and accessed through a web browser. Examples include Google Workspace and Salesforce.

I was playing some Bloons TD6, with all... | 0 | 2024-07-11T01:01:48 | https://dev.to/chigbeef_77/creating-a-new-fast-tower-defence-1j95 | gamedev | Defense? Defence? I'll use the 's' version because America.
I was playing some Bloons TD6, with all the nostalgia as I hadn't played a tower defense in years. However, going further and further into the waves, my CPU started crying. Now, my computer isn't exactly top of the line, but so what? My laptop can run DOOM 2016, using integrated graphics, so what is Bloons doing that's taking up all that CPU time and memory.
## Getting To Work
I decided the best way to find out is to make my own tower defense and try to make it as efficient as possible. Before I started, I had to make an aim. After not too long, I created a list.
1. Storage on disk should not be over 512mb
2. CPU should be under 10% (on my hardware, an R7)
3. Memory should stay under 256mb (this should be way more than enough)
4. Should be able to run 120TPS and 60FPS.
Seems pretty easy? And this is a *hard* limit. Realistically, the game should run at 1000TPS and 400FPS.
I had the idea, but I didn't have a name. After getting some ideas from ChatGPT, then disregarded it and chose [Sentinels of the Void](https://chigbeef.itch.io/sentinels-of-the-void).
## Starting the Project
I couldn't make a tower defense without a map to play with, so I need to make a map editor. This didn't need to be too hard, just a program that allowed me to play random lines in order. I then saved this to a file, and loaded it into the game. Now I just need the enemies to follow the path. This was my first issue. In a Plants Vs Zombies style TD, the enemies just walk in a straight line. But how do I make an enemy follow a path?
Here we show that we can use the `dx` and `dy` to find the angle. Using the angle we can get a way that an enemy can move, but what's even better about this is that we can multiply the new `dx` and `dy` by the enemy's speed so that each enemy can have its own movement.
When the enemy gets to the end of the line, we simply increment an index, and just do the same thing with the next line.
## Seeing the Optimizations
As I'm working I can see so many optimization I can make, but regardless, the game is running well below the target limitations, so I don't need to implement them. I could pre-calculated all Sine and Cosine values, but it's not useful right now to my productivity. However, I will be taking mental notes of these optimizations in future when I do come across issues.
Another optimization that I will implement is pre-rendering some graphics. For example, text can be an expensive render, now it's not game haltingly bad, but it's obviously more expensive than a rectangle. Because of this, what I can do is pre-render text onto an image, and use that image instead. This will probably be my biggest graphical computation save especially at the start of production of the game.
## Releasing the Game
Currently, V0.1 is out, and I'm close to finishing V0.2. The game has no art and at this point released with a map editor so that you can make your own levels for the game. I like adding modability to my games, so this is a small step towards that.
When I add art to the game I will do my best allow people to replace it with their own art, so they can change the game in any way they would like.
I would suggest [trying out the game](https://chigbeef.itch.io/sentinels-of-the-void) as it's only got a few minutes of gameplay. If you have any suggestions or feedback I would love to hear it. Lastly, I would love to head what you love most about Tower Defense games, because as much as I'm having fun making a game for efficiency, I also want it to be fun. | chigbeef_77 |
1,919,097 | 🐧👾💅 The First Bash Prompt Customization I NEED to Do - Linux | While I'm developing, the terminal prompt is one of the most frequently used tools in my workflow, so... | 0 | 2024-07-11T03:25:49 | https://dev.to/uxxxjp/the-first-bash-prompt-customization-i-need-to-do-linux-2e4p | linux, ubuntu, cli, dx | While I'm developing, the terminal prompt is one of the most frequently used tools in my workflow, so I like to make it look cool.
## Virgin Ubuntu
I'm using Mac to "run" Ubuntu through Multipass. The following command creates a new Ubuntu instance named cool-prompt and starts an interactive shell. The initial appearance is:
## PS1
We need to change the value of a variable called PS1 in the .bashrc file.
PS1 stands for "Prompt String 1". It specifically defines the primary prompt that appears before each command when the shell is ready to accept input.
`.bashrc` stands for "Bourne Again SHell Run Commands"; this file is a script that runs whenever the Bash shell is started.
## Config for Default User
The default user is the one you get out of the box, which in the image is ubuntu as shown previously.
Open the .bashrc file and edit PS1. You can use vi since it comes with Ubuntu:
```bash
vi ~/.bashrc
```
Navigate to the end of the file (use the 'G' shortcut in vi) and paste the following:
```bash
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
PS1='\[\033[01;32m\]@\u\[\033[00m\] \[\033[01;34m\]\W\[\033[00m\]\[\033[01;36m\]$(parse_git_branch)\[\033[00m\]\n$ '
```
This code will execute later at the end of the file and overwrite the value of PS1. If you know what you're doing and prefer, you can delete any previous manipulations of PS1.
This shell script defines a function to retrieve the current Git branch of a directory if it's a Git repository. It then formats the prompt with different colors for the current user's name, the current folder, and the Git branch (if applicable). Finally, it inserts a newline and $ to indicate the start of commands.
After editing the .bashrc file, every new shell session will use the new configuration. To apply the changes to the current shell prompt, use:
```bash
source ~/.bashrc
```
After sourcing .bashrc, your prompt should look like this:
In a git repo:
## Config for Root User
Youre all happy with your new prompt, but some task forces you to use the root user. To your surprise(especially if you're a noob like me), your prompt get uglier than ever.
Ok! Don't worry. Open `.bashrc` again, go to the end of the file, paste the same code from the previous section. This ensures that every time a new root session is initialized, your prompt configuration will be applied. Remember to source .bashrc in the current prompt if you want the changes to take effect immediately.
And we're done !🥳!
## There is more
There are much more configs possible in the shell prompt. Just to give a general idea the following link show some of the special characters that can be used in prompt variables https://www.gnu.org/software/bash/manual/html_node/Controlling-the-Prompt.html

**What exactly is the cloud, and why should you care?**
Well, there is a natural occurrence in which clouds form with only two possible outcomes: rain or not.
Another cloud has formed, this time not naturally, but artificially or virtually connecting several computers, servers, and storage facilities.
Within these computer connections, one can use someone else's computer or storage over the internet to conduct all of the typical tasks that he could have done on his local computer setup, but more easily and efficiently. This is referred to as **Cloud Computing**.
**Do you need to care about cloud computing?**
Yes. Because it will make your digital life easier, and you will not have to break the money to build up an infrastructure for your tiny startup or even large and established companies, because payment is typically Pay-As-You-Go. It also allows you to upscale easily and quickly because all computer resources are available on demand.
**Deployment Models**
In cloud computing, there is a concept called as deployment models. It simply refers to how we save our data in the cloud. The data can be saved in a dedicated cloud space. This is commonly referred to as _Private Cloud_. This can be pricey and takes longer to set up, but it gives the user complete control over his data
On the other hand, the _Public Cloud_ allows users to swiftly and affordably install data on shared storage supplied by cloud computing service providers.
_Hybrid Cloud_ is the choice to use the first and second, that is Private and Public together.
**Iaas, Paas and Saas.**
You may hear something like _IaaS, PaaS, and SaaS._ These are not sounds, but acronyms for the various **Cloud Service Models.** Simply put, cloud service companies supply these types of services.
-
Infrastructure as a service (IaaS) provides on-demand access to cloud-hosted real and virtual servers, storage, and networking. So you're merely employing computer hardware in the cloud to carry out your job.
-
PaaS (platform as a service) provides on-demand access to a cloud-hosted platform for application development, maintenance, and management.
-
SaaS, or software as a service, is on-demand access to ready-to-use, cloud-hosted application software. Like example Zoom for video conferencing and google docs
So next time you see or hear about the cloud, ask whether you need an umbrella or access to internet.

1,919,150 | The Open/Closed Principle in C# with Filters and Specifications | Software design principles are fundamental in ensuring our code remains maintainable, scalable, and... | 28,026 | 2024-07-11T01:34:25 | https://dev.to/moh_moh701/the-openclosed-principle-in-c-with-filters-and-specifications-3dd6 | dotnet, designpatterns, csharp |
Software design principles are fundamental in ensuring our code remains maintainable, scalable, and robust. One of the key principles in the SOLID design principles is the Open/Closed Principle (OCP). This principle states that software entities should be open for extension but closed for modification. Let’s explore how we can adhere to this principle through a practical example involving product filtering.
#### Initial Implementation: The Problem
Imagine we have a simple product catalog where each product has a name, color, and size. We need a way to filter these products based on various criteria. A straightforward implementation might look like this:
```csharp
public enum Color
{
Red, Green, Blue
}
public enum Size
{
Small, Medium, Large, Yuge
}
public class Product
{
public string Name;
public Color Color;
public Size Size;
public Product(string name, Color color, Size size)
{
Name = name ?? throw new ArgumentNullException(paramName: nameof(name));
Color = color;
Size = size;
}
}
public class ProductFilter
{
public IEnumerable<Product> FilterByColor(IEnumerable<Product> products, Color color)
{
foreach (var p in products)
if (p.Color == color)
yield return p;
}
public static IEnumerable<Product> FilterBySize(IEnumerable<Product> products, Size size)
{
foreach (var p in products)
if (p.Size == size)
yield return p;
}
public static IEnumerable<Product> FilterBySizeAndColor(IEnumerable<Product> products, Size size, Color color)
{
foreach (var p in products)
if (p.Size == size && p.Color == color)
yield return p;
}
}
```
While this implementation works, it’s easy to see how it can quickly become unmanageable. Each new filter criterion or combination of criteria requires a new method. This approach violates the Open/Closed Principle because the `ProductFilter` class needs to be modified each time a new filtering requirement is introduced.
#### Refactoring with OCP: The Solution
To adhere to the Open/Closed Principle, we need a way to extend our filtering functionality without modifying the existing code. We can achieve this by using the Specification pattern, which allows us to define criteria in a reusable and combinable way.
##### Step 1: Define Interfaces
First, we define two interfaces: one for specifications and one for filters.
```csharp
public interface ISpecification<T>
{
bool IsSatisfied(T item);
}
public interface IFilter<T>
{
IEnumerable<T> Filter(IEnumerable<T> items, ISpecification<T> spec);
}
```
##### Step 2: Implement Specifications
Next, we implement concrete specifications for color and size.
```csharp
public class ColorSpecification : ISpecification<Product>
{
private Color color;
public ColorSpecification(Color color)
{
this.color = color;
}
public bool IsSatisfied(Product p)
{
return p.Color == color;
}
}
public class SizeSpecification : ISpecification<Product>
{
private Size size;
public SizeSpecification(Size size)
{
this.size = size;
}
public bool IsSatisfied(Product p)
{
return p.Size == size;
}
}
```
##### Step 3: Combine Specifications
We can also create composite specifications to combine multiple criteria.
```csharp
public class AndSpecification<T> : ISpecification<T>
{
private ISpecification<T> first, second;
public AndSpecification(ISpecification<T> first, ISpecification<T> second)
{
this.first = first ?? throw new ArgumentNullException(paramName: nameof(first));
this.second = second ?? throw new ArgumentNullException(paramName: nameof(second));
}
public bool IsSatisfied(T item)
{
return first.IsSatisfied(item) && second.IsSatisfied(item);
}
}
```
##### Step 4: Implement the Better Filter
Finally, we implement the `BetterFilter` class that uses the specifications to filter products.
```csharp
public class BetterFilter : IFilter<Product>
{
public IEnumerable<Product> Filter(IEnumerable<Product> items, ISpecification<Product> spec)
{
foreach (var i in items)
if (spec.IsSatisfied(i))
yield return i;
}
}
```
#### Demonstration: Putting It All Together
Here’s a demonstration of how to use the refactored filtering system:
```csharp
public class Demo
{
static void Main(string[] args)
{
var apple = new Product("Apple", Color.Green, Size.Small);
var tree = new Product("Tree", Color.Green, Size.Large);
var house = new Product("House", Color.Blue, Size.Large);
Product[] products = { apple, tree, house };
var pf = new ProductFilter();
WriteLine("Green products (old):");
foreach (var p in pf.FilterByColor(products, Color.Green))
WriteLine($" - {p.Name} is green");
var bf = new BetterFilter();
WriteLine("Green products (new):");
foreach (var p in bf.Filter(products, new ColorSpecification(Color.Green)))
WriteLine($" - {p.Name} is green");
WriteLine("Large products:");
foreach (var p in bf.Filter(products, new SizeSpecification(Size.Large)))
WriteLine($" - {p.Name} is large");
WriteLine("Large blue items:");
foreach (var p in bf.Filter(products, new AndSpecification<Product>(new ColorSpecification(Color.Blue), new SizeSpecification(Size.Large))))
WriteLine($" - {p.Name} is big and blue");
}
}
```
#### Conclusion
By applying the Open/Closed Principle through the Specification pattern, we created a flexible and maintainable filtering system. The `BetterFilter` class is open for extension through new specifications but closed for modification, as we no longer need to change its implementation to add new filtering criteria.
This approach not only adheres to SOLID principles but also enhances the scalability and readability of our code, making it easier to maintain and extend in the future. | moh_moh701 |

****Environment Setup:
-
We will install the necessary libraries and configure the connection with the OpenAI API.
```
pip install openai streamlit
```
```
import openai
from dotenv import load_dotenv
import os
import streamlit as st
import time
load_dotenv()
api_key = os.getenv("OPENAI_API_KEY")
if not api_key:
raise ValueError("No API key provided for OpenAI")
openai.api_key = api_key
```
User Interface with Streamlit: We will develop a simple web interface where users can interact with the generative chatbot.
```
# Set the title for the Streamlit web app
st.title("My ChatGPT")
# Initialize session state for storing chat messages
if "messages" not in st.session_state:
st.session_state["messages"] = [{"role": "assistant", "content": "Hello, I'm ChatGPT, how can I assist you today?"}]
# Display existing chat messages
for msg in st.session_state["messages"]:
st.chat_message(msg["role"]).write(msg["content"])
# Check for user input and handle interaction with ChatGPT
if user_input := st.chat_input():
# Add user input to session state as a message
st.session_state["messages"].append({"role": "user", "content": user_input})
# Attempt to call OpenAI's ChatCompletion API with error handling
retries = 3
success = False
for attempt in range(retries):
try:
# Call the OpenAI ChatCompletion API with the current session messages
response = openai.ChatCompletion.create(
model="gpt-3.5-turbo",
messages=st.session_state["messages"]
)
# Get the response message from the API and add it to session state
response_message = response['choices'][0]['message']['content']
st.session_state["messages"].append({"role": "assistant", "content": response_message})
# Display the assistant's response in the chat interface
st.chat_message("assistant").write(response_message)
success = True # Mark the request as successful
break # Exit the retry loop if successful
except openai.error.RateLimitError as e:
# Handle rate limit errors by warning and retrying after 5 seconds
st.warning(f"RateLimitError: {e}. Retrying in 5 seconds...")
time.sleep(5)
except Exception as e:
# Handle other exceptions by displaying an error message
st.error(f"Error calling OpenAI API: {e}")
break
# Display an error message if the request was not successful after retries
if not success:
st.error("Could not complete request due to rate limit errors.")
```
**Result**
**Conclusion**
Creating a generative chatbot with Python and Streamlit is an endeavor that not only delves into natural language processing and machine learning but also showcases the potential of artificial intelligence to revolutionize digital interaction. | fiorelamilady | |

Khi nói về việc tăng hiệu năng tổng thể của một chương trình Java, chắc hẳn một số anh chị em Java developer sẽ nghĩ ngay đến multi-threading(tận dụng việc CPU đa nhân để xử lý song song các công việc cùng một lúc) với tư duy là: “Nhiều người cùng làm một việc thì bao giờ chả nhanh hơn một người làm”. Tuy nhiên, việc lạm dụng sử dụng multi-threading mà chưa thực sự hiểu cách hoạt động và tương tác giữa các luồng và các core của CPU có thể dẫn đến giảm hiệu năng của chương trình, thậm trí có thể dẫn đến việc chương trình chạy bị thiếu chính xác. Một trong những nguyên nhân phổ biến dẫn đến chương trình bị chạy sai có thể kể đến là race-condition, nhiều developer nghĩ chỉ cần sử dụng các từ khóa synchronized hay lock để giải quyết vấn đề race-condition và hiệu năng chương trình vẫn cao. Tuy nhiên liệu có phải thực sự như vậy. Trong bài viết này, chúng ta sẽ đi làm rõ điều đó.
Việc tận dụng tối đa sức mạnh của CPU đa nhân đa luồng khi phát triển phần mềm không phải là việc đơn giản, chính vì vậy việc hiểu cách hoạt động, tương tác và trao đổi dữ liệu giữa các luồng với nhau thông qua phần cứng là vô cùng quan trọng. Điều này còn được gọi với một key concept đó là mechanical sympathy. Khái niệm này lần đầu được một racer đưa ra như sau: “You don’t have to be an engineer to be be a racing driver, but you do have to have Mechanical Sympathy”, có thể dịch nôm na là khi đua xe thì việc cảm nhận xe, thậm chí là cảm nhận đến từng hơi thở của xe là điều vô cùng quan trọng. Sau này khái niệm này được Martin Thompson(Một chuyên gia về phát triển ứng dụng hiệu năng cao và độ trễ thấp) đưa vào việc phát triển phần mềm để mô tả về tầm quan trọng của việc hiểu phần cứng hoạt động như thế nào để khi lập trình phần mềm có thể tận dụng tối đa sức mạnh của phần cứng.
==> CPU hoạt động như thế nào ?
Khi đi mua CPU hay mua máy tính chúng ta vẫn thường quan tâm đến một số thông số phần cứng như RAM gì(DDR mấy), ổ cứng gì(HDD hay SSD)… tuy nhiên, có một thông số cũng rất nhiều anh em quan tâm đó là cache của CPU có lớn không. Tại sao chúng ta lại phải quan tâm đến dung lượng cache của CPU vậy?. Đúng vậy, đây là vùng nhớ gần nhất mà trung tâm xử lý của CPU lấy dữ liệu ra để tính toán, cho nên việc dung lượng cache nhiều cũng có thể làm cho chiếc PC hay laptop của chúng ta trở nên nhanh hơn.
Bây giờ hãy xem qua 1 core của CPU có gì nhé:
Như chúng ta thấy ở hình trên xuất hiện khá nhiều từ khóa Cache. Đúng vậy, đây chính là CPU Cache đã được đề cập ở trên khi mua PC hay laptop. CPU cache là bộ nhớ được dùng bởi bộ xử lý trung tâm của máy tính nhằm giảm thời gian truy cập dữ liệu trung bình từ bộ nhớ chính (DRAM). CPU Cache là một bộ nhớ nhỏ hơn, nhanh hơn RAM và lưu trữ bản sao của những dữ liệu thường xuyên được truy cập trên bộ nhớ chính. Hầu hết CPU đều có các bộ nhớ cache độc lập khác nhau, bao gồm cache chỉ dẫn và cache dữ liệu, nơi mà dữ liệu được xếp thành nhiều lớp khác nhau.
Mỗi CPU core đều có bộ nhớ cache riêng đó là bộ nhớ L1, L2 và bộ nhớ chung (share memory) L3 cho tất cả các lõi (CPU core) và CPU sẽ cache data lên đó. Vì vậy thay vì chương tình sẽ truy vấn và DRAM thì chương trình sẽ truy vấn vào bộ nhớ riêng L1, L2 trước nếu không thấy thông tin hợp lệ thì mới truy cập vào share memory L3 hoặc main memory (DRAM). Khi mà bộ xử lý cần phải đọc hay viết vào một vị trí trong bộ nhớ chính, nó sẽ tìm trong bộ nhớ cache đầu tiên. Nhờ vậy, bộ xử lý đọc hay viết dữ liệu vào cache ngay lập tức nên sẽ nhanh hơn nhiều so với đọc hay viết vào bộ nhớ chính.
Khi chương trình muốn truy cập vào bộ nhớ đầu tiên sẽ tìm trên internal caches L1 nếu không có thì cache miss sẽ xảy ra và chương trình sẽ tiếp tục tìm kiếm trên internal cache L2 và tiếp tục tìm kiếm ở share cache L3 và cuối cùng là tìm ở bộ nhớ chính DRAM, và so với việc lấy được dữ liệu từ L1 thì việc lấy dữ liệu ở DRAM sẽ lâu hơn gần 60 lần (60 nano second so với 1,2 nano second).
Ở trên là luồng lấy dữ liệu của trung tâm xử lý các core, vậy dữ liệu được giao tiếp giữa các cache này và RAM có dạng như thế nào? Đó chính là CacheLine.
CacheLine là dữ liệu được chuyển giữa bộ nhớ chính DRAM và CPU cache theo từng khối cố định kích cỡ. Có thể hiểu đơn giản là CacheLine là một bộ nhớ nhỏ làm trung gian giữa CPU Cache và Main Memory, giúp cho việc đọc hoặc ghi dữ liệu từ CPU Cache tới Main Memory.
Khi một cache line được sao chép từ bộ nhớ chính vào cache thì một cache entry được tạo ra. Nó sẽ bao gồm cả dữ liệu được sao chép và vị trí của dữ liệu yêu cầu (gọi là 1 tag).
Khi bộ xử lý cần đọc hoặc viết một vị trí trong bộ nhớ chính, nó sẽ tìm entry tương ứng trong cache đầu tiên. Cache sẽ kiểm tra nội dung của vị trí dữ liệu yêu cầu trong bất cứ cache line nào có thể có địa chỉ. Nếu bộ xử lý tìm thấy vị trí dữ liệu trong cache, một cache hit sẽ xảy ra. Tuy nhiên, nếu bộ xử lý không tìm thấy được vị trí dữ liệu trong cache, thì một cache miss sẽ xảy ra. Trong trường hợp cache hit, bộ xử lý đọc hoặc viết dữ liệu vào cache line ngay lập tức. Còn nếu là cache miss, cache sẽ tạo một entry mới và sao chép dữ liệu từ bộ nhớ chính, sau đó yêu cầu được đáp ứng từ nội dung của cache.
Cache line được quản lý với một bảng băm (hash-map) với mỗi địa chỉ lưu trong hash-map sẽ được chỉ định tới một cache line.
2. Các vấn đề thường gặp khi sử dụng multi-threading
2.1 False sharing
False sharing là hiện tượng mà khi các thread trên các core khác nhau muốn thay đổi dữ liệu trên 1 cache line dẫn đến việc hiệu năng của chương trình sẽ bị giảm đáng kể. Để dễ tưởng tượng ta cùng đi vào ví dụ sau:
Ta có hai biến X và Y được truy cập với 2 thread từ 2 CPU core khác nhau, một thread thay đổi X và sau vài ns (nano second) thread còn lại thay đổi Y.
Nếu hai giá trị X, Y trên cùng một cache line (xác định bằng cách băm địa chỉ của X và Y và cả hai đều ra cùng 1 cache line) giả dụ là cache line của CPU core chứa thread 1, thì lúc đó thread 2 còn lại sẽ phải lấy một bản copy của Y từ cache line của thread 1 từ L2, L3 hoặc DRAM, trường hợp đó ta gọi là False Sharing, và chính điều này cũng ảnh hưởng đáng kể tới hiệu xuất của chương trình.
2.2 Race condition
Chắc hẳn nếu bạn đã lập trình multi-threading thì không còn xa lạ với khái niệm race-condition nữa rồi. Race condition xảy ra khi có từ 2 thread trở lên cùng truy cập vào một vùng nhớ chung (shared memory) với ít nhất 1 thread thực hiện việc thay đổi giá trị trên vùng nhớ đó và làm dữ liệu không đồng bộ giữa các luồng dẫn đến sai sót khi tính toán.
Để dễ hình dung hơn, hãy bắt đầu với một ví dụ đơn giản là chúng ta cần tăng dần 1 biến đếm từ giá trị 0 đến 100*10^6. Chúng ta đều thấy con số 100M là khá lớn, vậy làm cách nào để tăng tốc độ đếm lên? Và theo tư duy thông thường thì ta sẽ nghĩ đến việc xử lý multi-thread tức là sử dụng nhiều hơn 1 thread để tính toán, ví dụ sau đây ta sử dụng 2 thread để xử lý việc tăng dần biến counter với hy vọng rằng tốc độ thực thi sẽ giảm một nửa ?
public void multiCounter() throws Exception {
// First thread
final Thread t1 =
new Thread(() -> {
for (int i = 0; i < 50_000_000; i++) {
sharedCounter++;
}
});
// Second thread
final Thread t2 =
new Thread(() -> {
for (int i = 0; i < 50_000_000; i++) {
sharedCounter++;
}
});
// Start threads
t1.start();
t2.start();
// Wait threads
t1.join();
t2.join();
System.out.println("counter=" + sharedCounter);
}
Cùng thử thực thi đoạn code trên và xem kết quả ra sao nhé.
Tada…
counter=55648901
counter=62176211
counter=52795666
Đúng vậy, kết quả là luôn khác 100M. Điều này xảy ra nguyên nhân chính là do race-condition.
Hẳn là sẽ có anh em thắc mắc là bây giờ ai dùng cách tạo thread như trên nữa. Tuy nhiên, trong source code trên tôi sử dụng cách tạo thread truyền thống để giả lập cho dễ hình dung. Việc sử dụng threadpool trong java cũng chỉ giúp quản lý các thread và giúp tiết kiệm việc khởi tạo thread chứ không hề giúp chúng ta xử lý gì trong vấn đề race-condition này. Chính vì vậy khi dùng executor của java để chạy lại ví dụ trên thì kết quả vẫn không có gì thay đổi. Biến counter vẫn không thể reach đến 100M.
ExecutorService executorService = Executors.newFixedThreadPool(2);
executorService.execute(new Runnable() {
@Override
public void run() {
for (int i = 0; i<50_000_00;i++){
sharedCounter++;
}
}
});
executorService.execute(new Runnable() {
@Override
public void run() {
for (int i = 0; i<50_000_00;i++){
sharedCounter++;
}
}
});
Thread.sleep(3000);
System.out.println(sharedCounter);
Một ví dụ thực tế hơn ngoài đời cho vấn đề race-condition đó là bài toán rút tiền ở cây ATM. Giả sử có 1 thẻ ATM và 1 thẻ Visa Debit cùng link đến 1 tài khoản ngân hàng và đi rút tiền cùng lúc. Trong tài khoản còn 50k vừa đủ làm bát bún real cool và cốc trà đá. Mình đồng thời rút ở cả 2 máy ATM 50k. Nếu không xử lý race-condition, mình sẽ may mắn rút được tổng cộng 100k ở cả 2 máy.
2.3 Happens-before Ordering trong java
Trước khi tìm hiểu Happens-before relationship ta sẽ tìm hiểu về một khái niệm trước đó là Instruction Reordering(IR). IR là cách mà các CPU hiện đại thực hiện sắp xếp lại thứ tự thực hiện các instruction để có thể thực thi chúng song song để tăng hiệu quả tính toán của CPU.
Cùng xem ví dụ sau nhé:
Sau khi CPU thực hiện Instruction Reordering lại thì thứ tự thực hiện các phép toán sẽ như sau:
Với các instruction trên được sắp xếp lại, CPU có thể thực hiện 3 instruction đầu tiên song song vì chúng không phụ thuộc lẫn nhau trước khi thực thi instruction thứ 4 -> tăng performance.
Tuy nhiên, trong vài trường hợp khi thực hiện thì Instruction Reordering sẽ dẫn đến việc chương trình thực hiện không đúng trên nhiều luồng như ví dụ sau đây:
Nếu CPU sắp xếp lại thứ tự thực hiện instruction (2) trước (1) thì ở Thread2 có thể xảy ra trường hợp điều kiện (3) đúng nhưng giá trị balance chưa được update -> chương trình sẽ không hoạt động đúng, vẫn lấy ra giá trị balance cũ. Ở đây Happens-before relationship sẽ giải quyết vấn đề đó, nó đảm bảo thứ tự thực hiện được giữ nguyên. Tất cả thay đổi xảy ra ở Thread1 trước khi ghi isDepositSuccess sẽ được nhìn thấy và cập nhật ở Thread2 khi đọc isDepositSuccess.
Đối với phần happen-before này, Chúng ta có thể sử dụng biến volatite, synchronized hay dùng các lớp Atomic để giải quyết.
3. Giải quyết các vấn đề về concurrent programming
3.1 Cơ chế loại trừ lẫn nhau(Mutual Exclusion- Mutex)
Trong ngành khoa học máy tính, tương tranh là một tính chất của các hệ thống bao gồm các tính toán được thực thi trùng nhau về mặt thời gian, trong đó các tính toán chạy đồng thời có thể chia sẻ các tài nguyên dùng chung. Hoặc theo lời của Edsger Dijkstra: “Tương tranh xảy ra khi nhiều hơn một luồng thực thi có thể chạy đồng thời.” Việc cùng sử dụng các tài nguyên dùng chung, chẳng hạn bộ nhớ hay file dữ liệu trên đĩa cứng, là nguồn gốc của nhiều khó khăn. Các tranh đoạt điều khiển (race condition) liên quan đến các tài nguyên dùng chung có thể dẫn đến ứng xử không đoán trước được của hệ thống. Việc sử dụng cơ chế loại trừ lẫn nhau(mutual exclusion) có thể ngăn chặn các tình huống chạy đua, nhưng có thể dẫn đến các vấn đề như tình trạng bế tắc (deadlock) và đói tài nguyên (resource starvation).
Tóm lại Mutual Exclusion là ta phải đảm bảo trong một thời điểm chỉ duy nhất 1 thread được thực thi vào share memeory.
Vậy để thực hiện mục tiêu trên thì cơ chế Loking là cơ chế gần như bắt buộc phải thực hiện, thường ta có hai cơ chế locking thường được sử dụng là Pessimistic Locking và Optimistic Locking.
3.2 Locking trong Java
Thực tế sử dụng lock sẽ gây lãng phí tài nguyên thread của CPU vì khi cơ chế locking được thực thi các thread khác sẽ bị block cho tới khi thread đang thực thi được giải phóng. Ngoài ra khi sử dụng lock không cẩn thận sẽ nảy sinh ra rất nhiều vấn đề như dead lock.
3.2.1 Sử dụng ReentrantLock
Cơ chế chung là lock và unlock. Một thread có thể lock nhiều lần và lưu ý phải unlock số lần bằng số lần lock để chương trình thực hiện đúng (vậy nên nó có tên gọi reentrant)
Chúng ta có thể giải quyết bài toán counter ở trên sử dụng reentrantLock như sau:
public class MutualExclusion {
private static int COUNTER = 0;
private static Lock LOCK = new ReentrantLock();
public static void main(String... args) throws Exception {
final Runnable increaseCounterFunc = () -> IntStream
.range(0, 50_000_000)
.forEach(Application::increaseCounter);
final var first = new Thread(increaseCounterFunc);
final var second = new Thread(increaseCounterFunc);
first.start();
second.start();
first.join();
second.join();
System.out.println(COUNTER);
}
private static void increaseCounter(int i) {
lock.lock();
lock.lock();
++COUNTER;
lock.unlock();
lock.unlock();
}
}
Chạy đoạn code trên, kết quả sẽ luôn luôn là 100M. Critical region đã được bảo vệ bởi khóa. Sẽ khóa trước khi thay đổi giá trị của COUNTER và mở khóa khi thực hiện xong. Do đó luôn luôn chỉ có 1 thread được truy cập để thay đổi giá trị. Race condition được giải quyết.
3.2.2 Insintric lock
Trong Java, ngoài việc sử dụng ReentrantLock để đảm bảo race condition. Thì sử dụng insintric lock cũng phổ biến không kém. Đó chính là việc sử dụng từ khóa synchronized. Cụ thể hơn, insintric lock có các loại: Synchronized method, Synchronized static method, Synchronized statement.
Với synchronized method, chỉ cần thêm từ khóa synchronized vào method là được. Khi đó, intrinsic lock xảy ra trên chính đối tượng gọi hàm. Nếu là static method thì intrinsic lock trên class đó. Cụ thể đoạn code cho bài toán tăng biến như sau:
private static synchronized void increaseCounter(int i) {
++COUNTER;
}
Với synchronized statement, ta sẽ đưa phần critical region vào synchronized block và phải khai báo đối tượng lock để thực hiện intrinsic lock. Sửa đoạn code trên như sau:
private static void increaseCounter(int i) {
synchronized(MutualExclusion.class) {
++COUNTER;
}
}
Lưu ý với synchronized statement, nếu khai báo đối tượng lock không cẩn thận rất sẽ có bug phát sinh. Phải đảm bảo tất cả các thread đều được lock trên một đối tượng duy nhất không đổi trong suốt quá trình. Ví dụ, nếu khai báo như sau, kết quả sẽ không đúng:
private static void increaseCounter(int i) {
synchronized(new Object()) {
++COUNTER;
}
}
Vì với mỗi lần cố gắng truy cập critical section, ta sẽ có các đối tượng khác nhau. Giống như việc 1 ổ khóa nhưng rất nhiều chìa có thể mở được, vậy khóa đó không an toàn.
3.2 CAS(Lock-Free)
Việc sử dụng các loại lock như phần trên đã đề cập hoàn toàn có thể đảm bảo được các việc các logic được tính toán đúng theo mong muốn của chúng ta. Tuy nhiên, việc sử dụng locking như vậy sẽ dẫn đến việc context-switching giữa các thread với nhau và làm cho chương trình của chúng ta bị giảm hiệu năng.
Giống như việc giao ca giữa các nhân viên làm ca ở các quán café vậy. Nhân viên ca trước phải tổng kết doanh thu của ca đó, sau đó bàn giao lại cho nhân viên ca mới. Context-switching là việc chuyển giao dữ liệu giữa các luồng hoạt động với nhau. Các luồng đang xử lý dữ liệu đó cần lưu lại data và trạng thái của thread đó trước khi switching, sau đó các luồng khác khi đảm nhận thì lại cần phục hồi data và trạng thái đã được lưu trữ bởi luồng trước đó. Việc này gây ra một chi phí không hề nhỏ làm cho hiệu năng của chương trình bị giảm đang kể.
Để giải quyết việc context-switching, chúng ta có thể sử dụng cơ chế CAS(Compare and swap). CAS là một kĩ thuật được sử dụng để thiết kế các thuật toán xử lý đồng thời lợi dụng cơ chế hoạt động của các core CPU. Khi nhiều thread cùng thực hiện CAS trên một biến, chỉ có duy nhất 1 thread truy cập thành công và thay đổi giá trị. Các thread còn lại không bị block, chúng vẫn thực hiện CAS nhưng không có gì thay đổi vì giá trị mới đã được thay đổi bởi luồng khác.
Trong Java, cơ chế CAS được thể hiện qua các lớp Atomic. Chúng ta có thể giải quyết bài toán counter trên sử dụng Atomic class như sau:
private static AtomicInteger COUNTER = new AtomicInteger(0);
private static void increaseCounter(int i) {
COUNTER.incrementAndGet();
}
Như vậy, việc sử dụng CAS đã hoàn toàn xử lý được context-switching, nhưng nếu đã có CAS rồi thì các phần lock sẽ không cần đến nữa à? Đúng vậy bản thân CAS cũng lại có những nhược điểm.
CAS thao tác trực tiếp với memory, thực hiện phép so sánh và thay đổi giá trị. Nhờ đó các thread không bị blocked. Tuy nhiên đó cũng là mặt hạn chế, chương trình trở nên phức tạp hơn trong trường hợp CAS fail, cần thực hiện retry cho đến khi thành công.
Ngoài ra, vì nó cần so sánh kết quả mới với vùng nhớ hiện tại, nếu vùng nhớ càng lớn, việc compare càng mất nhiều thời gian. Do đó cần lưu ý khi sử dụng các Atomic variable đặc biệt là AtomicReference.
Do đó, tùy từng bài toán và yêu cầu cụ thể để quyết định sử dụng cơ chế nào.
Bonus: Ứng cử viên nặng kí cho lập trình đa luồng
Tiện đang bàn về vấn đề đa luồng trong lập trình Java thì có một ngôn ngữ lập trình cũng nổi lên với các ưu điểm như “nhẹ”, “nhanh”, “gọn” trong những năm gần đây, đặc biệt là về khả năng xử lý đồng thời trong chương trình. Chắc các bạn cũng đã đoán được ngôn ngữ lập trình mà tôi đề cập đến ở đây. Đó chính là Golang.
Liệu Golang có thực sự mạnh mẽ trong việc xử lý đồng thời như vậy? Trong phần này tôi xin tập trung bàn đến phần xử lý đồng thời trong Golang với Goroutines và cùng xem Goroutines liệu có gì khác so với Thread trong Java nhé.
Goroutines là gì? Goroutines là những luồng gọn nhẹ trong Go, được khởi tạo với chỉ từ 2KB trong stack size có thể tăng hoặc giảm vùng nhớ tùy yêu cầu sử dụng.
Chúng ta hay cùng điểm qua một số khía cạnh giữa Goroutines và Thread trong Java nhé.
Bộ lập lịch(Scheduler)
- Java: Sử dụng native thread trong OS. Mỗi thread trong java ứng với một thread trong nhân hệ điều hành. Java không quyết định việc thread nào được chạy trong core của CPU mà việc đó hoàn toàn là do bộ lập lịch của hệ điều hành.
- Goroutines: Khác với Java, Golang không sử dụng native thread trong OS mà Go sử dụng Goroutines được sắp xếp để chạy trong các Thread. Các Goroutines sẽ không chạy theo bộ lập lịch của hệ điều hành mà chúng được chạy theo bộ lập lịch riêng gọi là Go runtime. Có thể có hàng ngàn Goroutines chạy trong 1 thread của OS. Nếu thread này bị block, 1 thread mới được tạo ra. Một vài goroutines sẽ ở lại thead cũ để xử lý tiếp, số goroutines còn lại dược chuyển qua thread mới để process tiếp.
Chính vì các Goroutines được quản lý và lên lịch chạy bởi Go runtine nên chúng được xử lý để có thể giảm thiểu chi phí tối đa về cho việc switching giữa các Goroutines với nhau.
Cụ thể hơn, đối với Java, khi một một thread bị block thì một thread khác sẽ được lập lịch để chạy thay thế. Trong thời gian switch 2 thread thì bộ lập lịch cần lưu trữ lại trạng thái của thread đó, cụ thể ở đây là tất cả các thanh ghi(registers) như PC (Program Counter), SP (Stack Pointer), segment registers, 16 XMM registers, FP coprocessor state, 16 AVX registers…. Điều này khiến cho chi phí switching thực sự là đáng kể.
Trong khi đó Golang thì khi switching giữa các Goroutines thì chỉ cần lưu trữ trạng thái của 3 thang ghi là Program Counter, Stack Pointer and DX.
Dung lượng
- Java: Các thread có thể được cấu hình dung lượng khi chạy chương trình bảng option –Xss. Tuy nhiên, khi không cấu hình option trên thì tùy thuộc vào VM có dạng 32bit hay 64bit mà dung lượng mặc định của Thread trong Java là 512Kb hay 1024Kb. Và đặc biệt là dung lượng của thread không thể resize khi chúng ta đã chạy chương trình.
- Go: Như đã đề cập trong khái niệm ở trên. Dung lượng của mỗi goroutines khi khởi tạo chỉ từ 2Kb và có thể tùy chỉnh tăng giảm vùng nhớ khi sử dụng.
- Như vậy chúng ta đã có thể thấy được việc dung lượng 1 thread trong java có thể lớn gấp từ 250 lần so với dung lượng của một goroutines.
Như vậy, với 2 tiêu chí đề cập ở trên, chúng ta đã có thể thấy được sự khác nhau cơ bản giữa “Thread” trong Golang và Thread trong Java. Tuy nhiên, để có thể hiểu sâu hơn về cách sử dụng và giao tiếp giữa các Goroutines thì có lẽ tôi sẽ dành riêng phần đó sang một bài viết khác.
4. Kết luận
Tóm lại, khi giải quyết một bài toán về hiệu năng không phải cứ sử dụng multi-thread là có thể tăng hiệu năng của chương trình, đôi khi một thread vẫn có thể chạy nhanh hơn nhiều thread.
Chính vì vậy, khi lập trình concurrency chúng ta cần cố gắng thiết kế các luồng đọc các dữ liệu khác nhau, cần kết hợp linh hoạt giữa đa luồng và đơn luồng, hạn chế sử dụng lock vì sẽ gây context switching ảnh hưởng đến hiệu năng của hệ thống . Làm được điều đó cũng chính là việc bạn đã trở thành một lập trình viên “Mechanical Sympathy”- nghe thấy tiếng thở của CPU từ đó các chương trình bạn tạo ra sẽ luôn tận dụng tối đa được sức mạnh của phần cứng và hiệu năng chương trình sẽ luôn được tối ưu.
Golang là 1 ngôn ngữ lập trình server-side mạnh mẽ về khả năng xử lý đồng thời, đặc biệt là với sự phát triển của microservices thì việc chia business ra các service nhỏ độc lập lại khiến cho việc tận dụng tối đa các điểm mạnh của các ngôn ngữ lập trình khác nhau. Hiện tại *** cũng đã có các team triển khai các services được viết bẳng Golang và cũng có khá nhiều bài nghiên cứu về Golang trên CoP nên nếu anh em muốn học thêm một ngôn ngữ back-end mới thì Golang cũng không phải là một lựa chọn tồi. | bu_0107 | |

## KisFlow with Kafka
### Sample source code
https://github.com/aceld/kis-flow-usage/tree/main/12-with_kafka
In this example, we use `github.com/segmentio/kafka-go` as the third-party Kafka Client SDK (developers can choose other Kafka Go tools).
```go
package main
import (
"context"
"fmt"
"github.com/aceld/kis-flow/file"
"github.com/aceld/kis-flow/kis"
"github.com/segmentio/kafka-go"
"sync"
"time"
)
func main() {
ctx := context.Background()
// Load Configuration from file
if err := file.ConfigImportYaml("conf/"); err != nil {
panic(err)
}
// Get the flow
flowOrg := kis.Pool().GetFlow("CalStuAvgScore")
if flowOrg == nil {
panic("flowOrg is nil")
}
// Create a new Kafka reader
reader := kafka.NewReader(kafka.ReaderConfig{
Brokers: []string{"localhost:9092"},
Topic: "SourceStuScore",
GroupID: "group1",
MinBytes: 10e3, // 10KB
MaxBytes: 10e6, // 10MB
MaxWait: 500 * time.Millisecond, // Maximum wait time
StartOffset: kafka.FirstOffset,
})
defer reader.Close()
var wg sync.WaitGroup
for i := 0; i < 5; i++ { // Use 5 consumers to consume in parallel
wg.Add(1)
go func() {
// Fork a new flow for each consumer
flowCopy := flowOrg.Fork(ctx)
defer wg.Done()
for {
// Read a message from Kafka
message, err := reader.ReadMessage(ctx)
if err != nil {
fmt.Printf("error reading message: %v\n", err)
break
}
// Commit the message to the flow
_ = flowCopy.CommitRow(string(message.Value))
// Run the flow
if err := flowCopy.Run(ctx); err != nil {
fmt.Println("err: ", err)
return
}
}
}()
}
wg.Wait()
return
}
func init() {
// Register functions
kis.Pool().FaaS("VerifyStu", VerifyStu)
kis.Pool().FaaS("AvgStuScore", AvgStuScore)
kis.Pool().FaaS("PrintStuAvgScore", PrintStuAvgScore)
}
```
## KisFlow with Nsq
### Sample source code:
https://github.com/aceld/kis-flow-usage/tree/main/13-with_nsq
This KisFlow consumer uses `github.com/nsqio/go-nsq` as the third-party SDK.
```go
package main
import (
"context"
"fmt"
"github.com/aceld/kis-flow/file"
"github.com/aceld/kis-flow/kis"
"github.com/nsqio/go-nsq"
)
func main() {
ctx := context.Background()
// Load Configuration from file
if err := file.ConfigImportYaml("conf/"); err != nil {
panic(err)
}
// Get the flow
flowOrg := kis.Pool().GetFlow("CalStuAvgScore")
if flowOrg == nil {
panic("flowOrg is nil")
}
// Create a new NSQ consumer
config := nsq.NewConfig()
config.MaxInFlight = 5
consumer, err := nsq.NewConsumer("SourceStuScore", "channel1", config)
if err != nil {
panic(err)
}
consumer.AddHandler(nsq.HandlerFunc(func(message *nsq.Message) error {
// Fork a new flow for each message
flowCopy := flowOrg.Fork(ctx)
// Commit the message to the flow
_ = flowCopy.CommitRow(string(message.Body))
// Run the flow
if err := flowCopy.Run(ctx); err != nil {
fmt.Println("err: ", err)
return err
}
return nil
}))
err = consumer.ConnectToNSQLookupd("localhost:4161")
if err != nil {
panic(err)
}
defer consumer.Stop()
select {}
}
func init() {
// Register functions
kis.Pool().FaaS("VerifyStu", VerifyStu)
kis.Pool().FaaS("AvgStuScore", AvgStuScore)
kis.Pool().FaaS("PrintStuAvgScore", PrintStuAvgScore)
}
```
##KisFlow with RocketMQ
###Sample source code:
https://github.com/aceld/kis-flow-usage/tree/main/14-with_rocketmq
Using `github.com/apache/rocketmq-client-go` as the RocketMQ consumer SDK.
```go
package main
import (
"context"
"fmt"
"github.com/aceld/kis-flow/file"
"github.com/aceld/kis-flow/kis"
"github.com/apache/rocketmq-client-go/v2"
"github.com/apache/rocketmq-client-go/v2/consumer"
"github.com/apache/rocketmq-client-go/v2/primitive"
)
func main() {
// Load Configuration from file
if err := file.ConfigImportYaml("conf/"); err != nil {
panic(err)
}
// Get the flow
myFlow := kis.Pool().GetFlow("CalStuAvgScore")
if myFlow == nil {
panic("myFlow is nil")
}
// Create a new RocketMQ consumer
c, err := rocketmq.NewPushConsumer(
consumer.WithGroupName("group1"),
consumer.WithNameServer([]string{"localhost:9876"}),
)
if err != nil {
panic(err)
}
err = c.Subscribe("SourceStuScore", consumer.MessageSelector{}, func(ctx context.Context, msgs ...*primitive.MessageExt) (consumer.ConsumeResult, error) {
for _, msg := range msgs {
// Commit the message to the flow
_ = myFlow.CommitRow(string(msg.Body))
}
// Run the flow
if err := myFlow.Run(ctx); err != nil {
fmt.Println("err: ", err)
return consumer.ConsumeRetryLater, err
}
return consumer.ConsumeSuccess, nil
})
if err != nil {
panic(err)
}
err = c.Start()
if err != nil {
panic(err)
}
defer c.Shutdown()
select {}
}

This infrastructure had to be seamlessly integrated with NHN's existing conventional gaming data systems, a process that was both complex and time-consuming.

Sui's architecture presented unique technical challenges, primarily due to its nascent data infrastructure which only provided basic raw data. This lack of refined, abstract data that is meaningful for project operations meant that additional resources were necessary to develop these capabilities. </span>

This week's adventure sort of doubles as a Product Launch... It's something I've dreamed about and hinted at for a while now, and previous adventures have even been building up to it... but it's becoming a real thing now and I couldn't be happier to share it with you!
## I'd rather watch a youtube video
{% embed https://www.youtube.com/watch?v=vZE6dPJS1vQ %}
## Finding a Problem to solve
I attend a church that records a video of the pastor's message each week and posts it to their Youtube channel. As I was browsing their channel, I noticed that it takes a while for a new video to get to 100 views, and I started digging into why that might be.
What I found was that it came down to _time_. The staff have a lot going on, both professionally and personally, and as a result they don't have the time required to market the youtube channel effectively. Some key points that I noted:
- The titles don't attract attention very well.
- Most of the videos don't have anything in the description field.
- There are no hashtags in use.
- There's no additional marketing of the video posting - we don't make use of shorts, or other channels like Reels or TikTok, to acquire new watchers and direct them to our content.
## Anybody can complain; Devs roll up their sleeves and do work!
Given my recent Adventures exploring AI capabilities, my brain was primed to solve this problem. I could build a Social Media Assistant to help my pals using Generative AI tools!
So here's the plan:
1. Start with the "finished" video file that they're going to upload
2. Transcribe the audio
3. Create vector embeddings out of the transcript
4. Push those into a RAG application pattern using a free LLM
5. Have the app do the work listed in the bullets above:
- Write a clickbait-y title
- Give me a description summary
- Find appropriate hashtags
- Write a list of discussion/reflection questions
- Write the social media email invitation to next week's services
- Find quotable moments in the message and clip them for use on short-form platforms
6. Drop all the outputs into a folder where the staff can review / tweak before they post it
### Uh, Blink, why not just automate the whole upload?
True, I could probably make it a completely automatic pipeline. Why stop there?
First of all, there's a trust issue to overcome. How do we know the model isn't going to hallucinate and leave our church with an embarrassing _faux pas_?
Second, full automation without human oversight is unhealthy. I'm fully on board with making all the of the work automatic - as long as a person is still governing its use. It's a safety thing, yeah, but it's also a philosophical stance. I don't like the idea of _replacing people_ with AI. I like the idea of _augmenting people's efforts_ with AI.
## Introducing... the PhilBott!
Our pastor's surname is "Philpott". In his honor, I named my robot buddy "the PhilBott"! 😏 You can find the code for the PhilBott on my [GitHub](https://www.github.com/LinkBenjamin/the-philbott). I've made it open-source and I have no intention of profiting from it - I'm a bit of a 'digital hippie' and I just want the information to be free, man...
## A Brief Tour for the Devs in the Room
Let's take a look at the parts of the PhilBott! There are several components, and I've tried hard to keep them coupled very loosely. First, here's the flow:
{% embed https://www.youtube.com/embed/vZE6dPJS1vQ?start=744&end=995 %}
Now that we have a big picture in mind, let's take a look at the first step: creating a transcript.
## Turning Sounds into Words
I elected to wrap this in a Python class so that it could be easily called from my main program.
A Transcripter takes a single input - the file name of an input video - and then it's ready to use. By "use", I mean to say that you call the `transcribe()` method and it will spit out a transcript.
There's one extra requirement for Transcripter, however: we need to have `ffmpeg` installed in order for it to work. We're using this to extract the audio from the mp4 - it creates a wav file and then strips it down to a mono channel. Once this is done, we can feed it to [vosk](https://alphacephei.com/vosk/), a python library & associated machine learning model that transcribes audio and creates a text file from it. One of the features of Vosk that we're taking advantage of is that it will mark the beginning & ending timestamp of every word that it transcribes. This is particularly important for our quotable short-form tool - we need to know where those quotes are in the video in order to clip them out!
## Transcripts become Vector Embeddings
I won't get too deep into these weeds here because we've covered it in a [previous Adventure](https://dev.to/linkbenjamin/the-adventures-of-blink-28-rags-to-riches-1adj). I used the same pattern and flow to make this work: We chunk the transcript, create vector embeddings, and then push them into a Chroma DB.
As with the transcripter, I made the RAG application into a Python class so it would be easier to implement in my main program.
## Stitching it all together
The main python program accepts 3 command-line parameters:
- The video file we're going to work on
- The config yaml file that we want to load up to tell the LLM what our outputs need to be
- The location of the output folder where our responses will live
It creates a Transcripter, transcribes the video, and feeds that data to a RAG App configuration. The RAG app loads all the data into Chroma and then joins it to the language model and invokes it to ask all the questions in our config.
## Wrapping up
To me, the PhilBott represents all of the AI learning I've been doing lately. It's sort of the place where I've joined all of my thoughts together and made something practical and useful out of them.
I think projects like this are important - because they force us, the technologists, the practitioners - to stop and think about the people around us and how our work can help them achieve more.

This infrastructure had to be seamlessly integrated with NHN's existing conventional gaming data systems, a process that was both complex and time-consuming. Further complicating the transition was NHN's existing reliance on an internal database and business intelligence (BI) tools. These systems, while effective within Web2 environments, were not initially designed to handle the nuances of blockchain data, thereby requiring substantial adaptation.</span>
<span data-raw-html="span" style="font-size:12pt;font-family:Arial,sans-serif;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Another major challenge arose from the adoption of the Sui Network, a non-EVM (Ethereum Virtual Machine) blockchain. Sui's architecture presented unique technical challenges, primarily due to its nascent data infrastructure which only provided basic raw data. This lack of refined, abstract data that is meaningful for project operations meant that additional resources were necessary to develop these capabilities. </span>
<span data-raw-html="span" style="font-size:12pt;font-family:Arial,sans-serif;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Additionally, despite Pebble’s span background in traditional game development and design, their understanding and capability to manage Web3 data were limited. This gap highlighted the necessity for a data provider with expertise in translating complex blockchain data into actionable insights for game development and enhancement.</span>

6. Conclusion
## 1. Introduction to Navigation in Flutter
Navigation is a fundamental aspect of mobile application development. In Flutter, navigation and routing are managed by a powerful and flexible set of APIs. Whether you need simple page transitions or complex route management, Flutter provides robust solutions to meet your needs.
## 2. Navigator.push and Navigator.pop
The most basic form of navigation in Flutter is through the Navigator class. The Navigator manages a stack of Route objects and provides methods for managing the stack.
### Example: Basic Navigation
To navigate to a new page, you use Navigator.push. To go back to the previous page, you use Navigator.pop.
```
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: FirstPage(),
);
}
}
class FirstPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('First Page')),
body: Center(
child: ElevatedButton(
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(builder: (context) => SecondPage()),
);
},
child: Text('Go to Second Page'),
),
),
);
}
}
class SecondPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('Second Page')),
body: Center(
child: ElevatedButton(
onPressed: () {
Navigator.pop(context);
},
child: Text('Back to First Page'),
),
),
);
}
}
```
## 3. Using Named Routes
Named routes offer a more organized and scalable way to navigate within your app. You define routes in the MaterialApp widget and refer to them by name.
### Example: Named Routes
First, define the routes in the MaterialApp:
```
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
initialRoute: '/',
routes: {
'/': (context) => FirstPage(),
'/second': (context) => SecondPage(),
},
);
}
}
class FirstPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('First Page')),
body: Center(
child: ElevatedButton(
onPressed: () {
Navigator.pushNamed(context, '/second');
},
child: Text('Go to Second Page'),
),
),
);
}
}
class SecondPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('Second Page')),
body: Center(
child: ElevatedButton(
onPressed: () {
Navigator.pop(context);
},
child: Text('Back to First Page'),
),
),
);
}
}
```
## 4. Implementing a Drawer
A Drawer is a sliding panel that allows users to navigate to different sections of your app. It’s typically used for main navigation.
### Example: Drawer Navigation
```
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: HomePage(),
);
}
}
class HomePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('Home Page')),
drawer: Drawer(
child: ListView(
padding: EdgeInsets.zero,
children: <Widget>[
DrawerHeader(
decoration: BoxDecoration(
color: Colors.blue,
),
child: Text(
'Navigation Drawer',
style: TextStyle(
color: Colors.white,
fontSize: 24,
),
),
),
ListTile(
leading: Icon(Icons.home),
title: Text('Home'),
onTap: () {
Navigator.pop(context);
},
),
ListTile(
leading: Icon(Icons.account_circle),
title: Text('Profile'),
onTap: () {
Navigator.push(
context,
MaterialPageRoute(builder: (context) => ProfilePage()),
);
},
),
],
),
),
body: Center(child: Text('Home Page Content')),
);
}
}
class ProfilePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('Profile Page')),
body: Center(child: Text('Profile Page Content')),
);
}
}
```
## 5. Using a Bottom Navigation Bar
The Bottom Navigation Bar is used to provide easy access to different sections of an app. It’s a common navigation pattern in mobile apps.
### Example: Bottom Navigation Bar
```

Ele inclui... | 27,960 | 2024-07-11T02:55:21 | https://dev.to/serradura/setup-para-ruby-rails-macos-5fa2 | beginners, ruby, rails, braziliandevs | Este artigo descreve como configurar um ambiente de desenvolvimento Ruby / Rails no macOS. Ele inclui a instalação do Visual Studio Code, Asdf, Ruby, NodeJS, SQLite, Rails e Ruby LSP (plugin para o VSCode).
Para seguir este tutorial, basta copiar e colar os comandos no terminal. Caso encontre algum problema, deixe um comentário que eu tentarei te ajudar. 😊
## Instalação do Homebrew
O Homebrew é um gerenciador de pacotes para macOS. Ele facilita a instalação de softwares e ferramentas no sistema. Para instalá-lo, execute o comando abaixo:
```sh
# https://brew.sh
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
```
Esse comando solicitará permissão para instalar o Homebrew. Pressione `Enter` para continuar e insira a senha do seu usuário quando for solicitado.
Ao final da instalação, execute os comandos indicados para habilitar o Homebrew no terminal.
Exemplo (baseado na imagem acima):
```sh
(echo; echo 'eval "$(/opt/homebrew/bin/brew shellenv)"') >> ~/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"
```
## Instalação do Asdf
asdf é um gerenciador de ferramentas e suas diferentes versões. Ele permite instalar, gerenciar e alternar entre várias versões de Ruby, NodeJS, dentre outros programas e linguagens de programação. Execute os comandos abaixo para fazer a sua instalação.
```sh
# Instale as dependências
brew install coreutils curl git
# Instale o asdf
# -- https://asdf-vm.com/guide/getting-started.html#_2-download-asdf
git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.14.0
# Configure para inicializar no terminal
echo '. "$HOME/.asdf/asdf.sh"' >> .zshrc
echo '' >> .zshrc
# Configure o autocomplete
echo '# append completions to fpath' >> .zshrc
echo 'fpath=(${ASDF_DIR}/completions $fpath)' >> .zshrc
echo '# initialise completions with ZSH\’s compinit' >> .zshrc
echo 'autoload -Uz compinit && compinit' >> .zshrc
source ~/.zshrc
```
## Instalação do Ruby
Ruby é a linguagem de programação utilizada no framework Ruby on Rails. Os comandos abaixo instalam a última versão do Ruby e a definem como a padrão do sistema.
```sh
# Instale as dependências de compilação
# -- https://github.com/rbenv/ruby-build/wiki#macos
brew install openssl@3 readline libyaml gmp
# Adicione o plugin ao asdf
asdf plugin add ruby
# Instale a última versão
asdf install ruby latest:3
```
Após a instalação, execute os comandos abaixo para definir a versão padrão do Ruby e atualizar o RubyGems (gerenciador de bibliotecas do Ruby).
```sh
# Verifique a versão que foi instalada
asdf list ruby # Deverá aparecer algo como:
# 3.3.4
# Defina a versão obtida como a padrão do sistema
asdf global ruby 3.3.4
```
Abra um nova tab no terminal (`cmd + t`) e execute os seguintes comandos:
```sh
# Verifique a versão padrão
ruby -v
# Atualize o RubyGems
gem update --system
```
## Instalação do Visual Studio Code
Visual Studio Code é um editor de código-fonte gratuito desenvolvido pela Microsoft para Windows, Linux e macOS.
Os comandos abaixo, baixam e instalam o Visual Studio Code. Além disso, o editor será configurado como o padrão do terminal.
```sh
brew install --cask visual-studio-code
# Adicione o Visual Studio Code como editor padrão do terminal
echo 'export EDITOR="code --wait"' >> ~/.zshrc
```
## Instalação do Ruby LSP no Visual Studio Code
O Ruby LSP é um plugin para VSCode que fornece recursos como autocompletar, formatação dentre outros, tanto para Ruby quanto para Rails.
```sh
# Instale a gem do Ruby LSP
gem install ruby-lsp
# Instale a extensão do Ruby LSP no Visual Studio Code
code --install-extension shopify.ruby-lsp
```
## Instalação do NodeJS
NodeJS é uma plataforma de desenvolvimento de aplicações em JavaScript. O node (ou nodejs) é utilizado pelo Rails para compilar assets (como CSS e JavaScript).
Os comandos abaixo instalam a última versão e a definem como a padrão do sistema.
```sh
# Adicione o plugin ao asdf
asdf plugin add nodejs
# Instale a última versão
asdf install nodejs latest
# Verifique a versão que foi instalada
asdf list nodejs # Deverá aparecer algo como:
# 22.4.1
# Defina essa versão como a padrão do sistema
asdf global nodejs 22.4.1
# Faça a instalação do yarn
npm install -g yarn
# Verifique a versão padrão
node -v
```
## Instalação do SQLite
SQLite é um banco de dados SQL embutido. Ou seja, ele é um banco de dados que não requer um servidor separado já que tudo é armazenado em um único arquivo.
```sh
brew install sqlite
# Verifique a versão que foi instalada
sqlite3 --version
```
## Instalação do Rails
Rails é um framework WEB escrito em Ruby. Ele é utilizado para desenvolver aplicações seguindo o padrão MVC (Model-View-Controller).
```sh
gem install rails
# Verifique a versão que foi instalada
rails -v
# Execute o comando abaixo caso rails -v apresente algum problema:
# Exemplo:
# Rails is not currently installed on this system. To get the latest version, simply type:
# $ sudo gem install rails
source ~/.zshrc
```
## Criando um projeto Rails
Visando testar a instalação do Ruby e do Rails, vamos criar um projeto para verificar se tudo está funcionando.
```sh
# Vá para o diretório home
cd ~
# Crie uma pasta para organizar seus projetos
mkdir Workspace
# Entre na pasta
cd Workspace
# Crie um novo projeto Rails
# O banco de dados padrão é o SQLite
rails new myapp
# Acesse a pasta do projeto
cd myapp
# Crie o banco de dados
bin/rails db:create
# Inicie o servidor
bin/rails s
```
Abra outra aba no terminal (`cmd + t`) e execute o comando para acessar a aplicação no navegador:
```sh
# Irá para a pasta do projeto
cd ~/Workspace/myapp
# Abre a aplicação no navegador
open http://localhost:3000
```
## Criando um gerenciador de contatos
O comando `bin/rails g scaffold` cria um CRUD (Create, Read, Update, Delete) para um modelo. Ou seja, através dele é possível criar, listar, editar e excluir registros de um banco de dados através de uma interface WEB.
```sh
# Crie um scaffold para a entidade Person
bin/rails g scaffold Person first_name last_name email birthdate:date
# Execute as migrações para criar a tabela no banco de dados
bin/rails db:migrate
# Inicie o servidor (caso não esteja rodando)
# bin/rails s
# Acesse o gerenciador de contatos no navegador
open http://localhost:3000/people
```
Navegue pelo sistema e teste as funcionalidades de listagem, cadastro, visualização, edição e exclusão de contatos.
## Melhorando a aparência da aplicação
Visando melhorar o visual do sistema, vamos adicionar o Pico CSS versão class-less, que como o nome sugere não faz uso classes CSS. Ou seja, basta adicionar as tags HTML para obter um estilo bonito e padronizado.
```sh
# Vá para pasta do projeto
cd ~/Workspace/myapp
# Abra o VSCode
code .
```
Dentro do VSCode, abra o arquivo `app/views/layouts/application.html.erb` (utilize o `cmd + p` para buscar o arquivo) e adicione o seguinte trecho de código dentro da tag.`<head>`:
```html
<link
rel="stylesheet"
href="https://cdn.jsdelivr.net/npm/@picocss/pico@2/css/pico.classless.min.css"
/>
```
Nesse mesmo arquivo, envolva o conteúdo da tag `<body>` com uma tag `<main>`:
```html
<body>
<main><%= yield %></main>
</body>
```
Após essas alterações, acesse o navegador e recarregue para ver o novo visual de todas as páginas do sistema.
## Adicionando validações ao modelo Person
Embora funcional, o gerenciador de cadastro não possui validações. Vamos adicionar algumas para garantir que os dados informados sejam válidos.
Através do VSCode, abra o arquivo `app/models/person.rb` (utilize o `cmd + p` para buscar o arquivo) e adicione as validações:
```ruby
validates :first_name, :last_name, presence: true
validates :email, format: /@/, allow_blank: true
```
Volte o navegador e tente cadastrar/editar uma pessoa sem informar o nome ou o e-mail (sem `@`).

Here are some key points about evening primrose:
Appearance: It typically has tall, branching stems, with yellow flowers that bloom in the evening, hence its name.
Lifecycle: It is a biennial plant, meaning it completes its lifecycle over two years. In the first year, it forms a rosette of leaves, and in the second year, it sends up a flowering stalk.
Uses
Medicinal: Evening primrose oil (EPO), extracted from its seeds, is rich in gamma-linolenic acid (GLA), an omega-6 fatty acid.
Skin Health: EPO is used to treat conditions like eczema, psoriasis, and acne.
Women's Health: It's often recommended for premenstrual syndrome (PMS) and menopausal symptoms.
Anti-inflammatory: It has properties that can help with inflammatory conditions such as rheumatoid arthritis.
Dietary Supplement: EPO is available in capsule form and is used as a dietary supplement for its purported health benefits.
Traditional and Folk Medicine
Evening primrose has been used by Native Americans for various purposes, including as a poultice for bruises and wound healing, and as a treatment for gastrointestinal disorders.
Cultivation
Growing Conditions: It prefers well-drained soil and can thrive in poor soil conditions. It's drought-tolerant and can grow in full sun to partial shade.
Propagation: It is usually grown from seeds. Seeds can be sown directly in the garden in spring or autumn.
Potential Side Effects
Safety: EPO is generally considered safe for most people, but it can cause side effects like stomach upset, headache, and dizziness. It might also interact with certain medications, such as blood thinners.
Pregnancy: Its use during pregnancy should be discussed with a healthcare provider due to potential risks.
• [What are the benefits of taking evening primrose oil](https://www.theprimrose.net/)?
Research
Effectiveness: Some studies support the benefits of EPO for certain conditions, while others show mixed results. More research is needed to confirm its efficacy for many of its claimed benefits.
Evening primrose and its oil are valued for their potential health benefits, especially in skin and women's health. However, it's always best to consult a healthcare provider before starting any new supplement.

1,919,182 | 7 Awesome Career Tips Your Manager Will Never Tell You | While starting a career, your immediate manager becomes the guide to finding your feet in the... | 0 | 2024-07-11T03:14:15 | https://dev.to/dishitdevasia/7-awesome-career-tips-your-manager-will-never-tell-you-3lhn | developers, careerdevelopment, career, softwaredevelopment |
While starting a career, your immediate manager becomes the guide to finding your feet in the organization.
You could become very close and mimic your decisions based on how your manager will handle situations.
While this is good at the start, it may not help you in the long run. Your manager, at some point, may go higher or change jobs.
You could get a new leader who has a unique style of working.
All these scenarios could derail your career if you had kept all the eggs in one basket.
So these are strategies you can use to stay relevant in the industry.
Your immediate manager may not want you to tell you or may not be aware of themselves.
Key steps are:
- Your career — Your responsibility
- Find a mentor
- Communication is more important than tech skills
- Keep updating your resume
- Keep giving interviews
- Your Career — Your Responsibility
If there is one thing that I want you to take away from this post, it is this.
> Your manager is not in charge of your career. You are.
It is one of the most basic mistakes that most beginners and some mid-senior guys make.
They hinge their career on a particular manager or a leader.
It is an excellent strategy as long as the person is your manager.
But managers change, people move, organization changes structure.
You may find you will need to hinge on another person and that person may not share the same view.
It is also hard for you to accept this as then everything that happens in your career is your actions.
Your situations and circumstances can change. A financial crisis or a pandemic strikes you. But what determines your resilience is your response to those changing circumstances.
## Find a mentor
I learned this the hard way. When I started, I never thought I needed mentors. After a few knocks in the career and the job, I realized I needed someone to tell me where I am going wrong.
**Mentors are the sounding board for you.** Sometimes, you could see yourself tripping even you hear yourself talking about the problem to your mentor. They may not even need to give you any guidance and you will be on your way.
Selecting an excellent mentor is a challenge, I admit. The best person would be to ask your managers for guidance and they will either work out a way to find a mentor for you if they themselves cannot do it.
## Communication is more important than tech skills
In the tech world, notifications, alerts, and emails swamp us. There is also the never-ending stream of meetings. All this should make communication a second nature. But this is not true. Communication is the least looked at aspect during appraisal, as the benefits of clear communication are intangible.
There are multiple communications that happen:
- Communicating with your peers
- Communicating with stakeholders
- Communicating with leaders
- Communicating with other peers in different team
Each of these communication threads requires different words, tones, and content. Many of the root causes of issues that we observe are because of a missing a vital piece of information.
Learning to communicate is a skill. Unless you work on it, it will never improve. I have provided a few aspects that you can look at:
- Communicate in a group setting, such as presenting a solution or best practices.
- Articulating a problem statement when hit with a technical challenge
- Identifying the level of detail each type of audience needs such as a Business Analyst may not need all the technical debrief while a peer engineer might need all the jargon.
- Avoid talking in jargon
## Organization’s goal does not align with your career goals
The organization’s goal is to increase business. It needs happy customers and employees. But, very few organizations realize that a happy employee can only make the customer happy.
You handle your career goals. What an organization thinks is not in your sphere of influence.
This will lead you to subscribe to newsletters and events outside your work. If you are looking after your career, your value to your company increases and thus, the organization looks after you.
You could get special education/training from the organization itself, which is given only to top performers. It will give you a definite leg up if you are looking to move up the ladder.
## Keep updating your resume
Industry dynamics are outside the control of your company. Most of the time, even your managers might find themselves flat-footed with the direction in which the industry moves. Industry requirements may change. You need to be prepared for any scenario. It could only happen if you are regular in updating your resume.
The next question will be what will you update.
One of the basic approaches is to update the achievements you make within the project.
It becomes your log of the work you do. This helps both having something to write during appraisal as well in the job market.
The other hidden aspect is you do a review of your skills in your resume. You will identify the gaps in your skillset that you may need with the changing trends in the industry. It gives you the opportunity to discover gaps and create plans to learn the new technologies. It will lead you to take training that you wouldn’t have thought about if you were not reviewing your resume at regular interviews.
## Keep giving interviews
The market has many opportunities. Your workplace may be the best place to be in. But your team only faces limited challenges and you cannot grow beyond the challenges your team faces. You are also not aware of how the market dynamics are changing. Giving regular interviews gives you a view of which skills are on an uptrend.
The other aspect is pure practice.
> Interviews are uncomfortable.
You will communicate your experiences better as you give more interviews. Your experiences come alive and you could present a way better self when you have done it many times.
The interview is also a great place to identify knowledge gaps in your experience with the technology.
You go back and read the documentation for the questions you couldn’t answer.
It helps in filling the knowledge gaps which you would never know and this would help you in your current workplace.
The last one is you might just get a better company to work with. You will never know about this opportunity if you never go to interviews.
When you get a wonderful opportunity, it might look like good fortune. But it was your willingness to attend those interviews and to feel uncomfortable that landed you the offer.
It is always easier to find a job if you have one in hand. Keeping a lookout keeps you ready for the next challenge.
## Network outside your organization
A manager may never ask you to attend a meetup in your city unless there is an immediate benefit to attending it. But keeping an evening free to learn about the happening in the industry would keep you in good stead. You will get new ideas which you wouldn’t have thought of if you had never gone out.
You will talk with cool people within the industry, and it may lead you to your mentors.
You may learn about a new opportunity that may align more with your career goals compared to the current one.
If nothing else, you get a free pizza and a beer.
You can also skip going to meetups if you work at client locations. You get to meet many people from other firms and it is a good place to know about other firms and make meaningful connections.
## Conclusion
I want to highlight a caveat. I am not suggesting to keep on changing jobs. But these steps will keep you abreast of the happenings within the industry.
You may get ideas you can bring into your own organization and your organization will benefit from your industry knowledge. So these steps help you get industry knowledge and keep your skills relevant.

1,919,197 | Cloud Migration Strategies: Your Roadmap to a Successful Transition | Cloud migration has become a strategic imperative for businesses seeking to enhance agility,... | 0 | 2024-07-11T03:27:13 | https://dev.to/unicloud/cloud-migration-strategies-your-roadmap-to-a-successful-transition-gli | Cloud migration has become a strategic imperative for businesses seeking to enhance agility, scalability, and cost-efficiency. However, the transition from on-premises infrastructure to the cloud can be complex and fraught with challenges if not approached strategically. This guide delves into essential [cloud migration](https://unicloud.co/migration-services.html) strategies, equipping you with the knowledge to navigate this transformative process effectively.
## Understanding Cloud Migration
Cloud migration is the process of moving applications, data, and infrastructure from on-premises data centers to cloud-based environments. The motivations for migrating to the cloud vary, but common drivers include cost reduction, improved agility, enhanced scalability, and access to advanced cloud-native services.
## Key Cloud Migration Strategies
Rehost (Lift and Shift): This approach involves replicating your existing applications and data onto cloud infrastructure with minimal changes. It's a quick way to get started with cloud migration but may not fully leverage the benefits of cloud-native features.
**1.Refactor (Replatform):** This strategy involves making some modifications to your applications to better suit the cloud environment. You might switch to cloud-managed services or optimize your code for cloud-specific features.
**2. Rearchitect (Modify):** This approach involves redesigning your applications to take full advantage of cloud-native services and architectures. It offers the greatest potential for innovation and scalability but requires more time and effort.
**3. Rebuild (Replace):** This strategy involves completely rebuilding your applications from scratch using cloud-native technologies. It's a good option for legacy applications that are difficult to refactor or re-platform.
**4. Retain (Do Nothing):** Some applications may not be suitable for migration or may not offer significant benefits from being moved to the cloud. In these cases, it might be best to retain them on-premises.
## Choosing the Right Cloud Migration Strategy
The optimal migration strategy for your organization depends on several factors, including:
**Application Complexity:** Simple applications may be suitable for rehosting, while complex applications may require refactoring or rearchitecting.
**Business Goals:** Consider your business objectives for cloud migration. Are you seeking to reduce costs, improve agility, or enhance scalability?
**Budget and Timeline:** Your budget and timeline will influence the scope and pace of your migration project.
**Technical Expertise:** The availability of in-house expertise and external support will impact your ability to execute different migration strategies.
## Best Practices for Cloud Migration
**Thorough Planning:** Develop a comprehensive migration plan that outlines the scope, timeline, resources, and risks associated with the project.
**Data Migration:** Prioritize data migration and ensure data integrity throughout the process.
**Security:** Implement robust security measures to protect your applications and data in the cloud.
**Monitoring and Optimization:** Continuously monitor your cloud environment and optimize your resources for cost-efficiency and performance.
**Training and Upskilling:** Ensure your team is equipped with the necessary skills to manage and maintain your cloud infrastructure.
## Conclusion
Cloud migration is a complex but rewarding journey. By choosing the right strategy, following best practices, and leveraging expert guidance, you can successfully transition to the cloud and reap the benefits of increased agility, scalability, and innovation.

In the following table, column A is the category, and column B includes one or multiple lines of text where the line break is the separator.
The task is to expand each multi-line cell under column B into multiple cells and copy the column A value.
Solution:
Use _**SPL XLL**_ to do this:
```
=spl("=?.news@q(~2.import@si();[get(1)(1),~])",A2:B4)
```
As shown in the picture below:
**Explanation**:
news@q function generates a new sequence by computing members of an existing sequence; ~2 is the 2ndmember of the current variable; import@si parses a string into a sequence of single-line strings according to the carriage return; get() function returns the loop variable according to the layer number during a multilayer loop. | judith677 |
1,919,205 | Detailed Guide to Configuring DBLink from GBase 8s to Oracle | Connecting GBase 8s with Oracle databases is a common requirement when building enterprise-level data... | 0 | 2024-07-11T03:51:14 | https://dev.to/congcong/detailed-guide-to-configuring-dblink-from-gbase-8s-to-oracle-1g4m | database | Connecting GBase 8s with Oracle databases is a common requirement when building enterprise-level data solutions. In the previous article, we covered the configuration of DBLink from Oracle to GBase 8s. This article will guide you through configuring DBLink from GBase 8s to Oracle, enabling interoperability between the two database systems.
## 1. Installing GBase Gateway
### 1) Configure `/etc/services`
```sql
vi /etc/services
gbase350_O2_3 9100/tcp
```
### 2) Extract Installation Package
```sql
tar -xvf GBaseGateway_1.0.0_1.tar.gz
```
### 3) Modify Configuration Files
```sql
cd GBaseGateway_1.0.0_1/conf/gbase8s
vi instance_name.properties
[gbasedbt]
gbase8s_IP=172.24.5.103
gbase8s_port=9100
gbase8s_user=gbasedbt
gbase8s_pwd=111111
gbase8s_encode=DB_LOCALE=zh_CN.GB18030-2000;CLIENT_LOCALE=zh_CN.GB18030-2000
```
The transparent gateway configuration file (`GBaseGateway_1.0.0_1/conf/conf.properties`) can be left as default, with the default port being 9898.
### 4) Start the Transparent Gateway
```sh
sh gbaseGatewayServer.sh start
```
### 5) Add Transparent Gateway Connection Information to SQLHOSTS
```sh
dblink_gateway onsoctcp 172.24.5.103 9898
```
## 2. Create DBLink and Test
```sql
set environment sqlmode 'oracle';
drop database link dblinktest2;
create public database link dblinktest2 connect to 'oracle' with system identified BY 'PBData#2014'
USING '(
DESCRIPTION = (
ADDRESS=(PROTOCOL = TCP)
(HOST=172.24.5.99)
(PORT=1521)
)
(CONNECT_DATA =
(SERVER=DEDICATED)
(SERVER=DEDICATED)
(SERVIC_NAME=db12c)
)
)';
select * from dblink_tab1@dblinktest2;
```
**Note:** If you encounter the following Oracle error:
```sql
java.sql.SQLException: Non supported character set (add orai18n.jar in your classpath): ZHS16GBK
```
Copy `orai18n.jar` from the Oracle installation directory to the gateway's `lib` directory and restart the gateway.
## 3. Configuring DBLink from Oracle to CM (Similar to Oracle to GBase 8s)
### 1) Add CM Data Source to `odbc.ini` (change instance name to `cm_update`)
```ini
[cm_demo]
Driver=/opt/gbase/lib/cli/iclit09b.so
Description=GBase ODBC DRIVER
Database=gbasedb
LogonID=gbasedbt
pwd=GBase123
Servername=cm_update
CLIENT_LOCALE=zh_cn.utf8
DB_LOCALE=zh_cn.utf8
```
### 2) Configure `sqlhosts` File
```sql
db_group group - - i=1
gbase01 onsoctcp 172.16.3.45 9088 g=db_group
gbase02 onsoctcp 172.16.3.46 9088 g=db_group
cm_update group - - i=3,c=0
oltp1 onsoctcp 172.16.3.45 18888 g=cm_update
oltp2 onsoctcp 172.16.3.46 18888 g=cm_update
cm_read group - - i=4,c=0
read1 onsoctcp 172.16.3.45 19999 g=cm_read
read2 onsoctcp 172.16.3.46 19999 g=cm_read
```
### 3) Add Oracle HS File for CM
```sh
cd $ORACLE_HOME/hs/admin (Navigate to the HS admin directory)
cat <<! >initcm_demo.ora #init<monitor instance name>.ora
HS_FDS_CONNECT_INFO=cm_demo
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_SHAREABLE_NAME=/usr/lib64/libodbc.so
HS_NLS_NCHAR = UCS2
HS_FDS_FETCH_ROWS=1000
HS_RPC_FETCH_REBLOCKING=OFF
set ODBCINI=/etc/odbc.ini
set GBASEDBTDIR=/opt/gbase
set GBASEDBTSERVER=cm_update
set GBASEDBTDIR=/opt/gbase
set GBASEDBTSQLHOSTS=/opt/gbase/etc/sqlhosts
set PATH=/opt/GBASE/gbase/bin:/u01/app/oracle/product/11.2.0/db_1/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin:/usr/lib64/qt-3.3/bin:/home/oracle/perl5/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/oracle/.local/bin:/home/oracle/bin:/home/oracle/bin
set LD_LIBRARY_PATH=/opt/gbase/lib/:/opt/gbase/lib/cli:/opt/gbase/lib/esql:include:/u01/app/oracle/product/11.2.0/db_1/lib
set DELIMIDENT=y
!
```
### 4) Configure Oracle Listener
- Modify the `listener.ora` file:
```sh
cd $ORACLE_HOME/network/admin/
vi listener.ora
```
Add the following lines:
```sh
(SID_DESC =
(ORACLE_HOME= /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = cm_demo)
(PROGRAM=dg4odbc)
)
```
- Modify the `tnsnames.ora` file:
```sh
cd $ORACLE_HOME/network/admin/
vi tnsnames.ora
```
Add the following lines:
```sh
cm_demo =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.3.47)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = cm_demo)
)
(HS=OK)
)
```
### 5) Restart the Listener
```sh
lsnrctl reload
lsnrctl status # Should display odbc_demo as normal, state unknown
tnsping cm_demo # Should display OK if normal
```
### 6) Create DBLink and Test
```sql
su - oracle
sqlplus / as sysdba
SQL> create database link gbasecmlink connect to "gbasedbt" identified by "GBase123" using 'cm_demo';
SQL> select * from test@gbasecmlink;
SQL> insert into test@gbasecmlink values(88);
```
This article provides detailed steps for configuring DBLink from GBase 8s to Oracle, enabling database professionals to achieve data interaction and integration between the two systems. Mastering these configuration techniques can effectively support complex data processing tasks and decision-making analysis. | congcong |

1,919,207 | Improve TensorFlow model load time by ~70% using HDF5 instead of SavedModel | In our ongoing work running DeepCell on Google Batch, we noted that it takes ~9s to load the model... | 27,298 | 2024-07-11T03:55:16 | https://dev.to/dchaley/improve-tensorflow-model-load-time-by-70-using-hdf5-instead-of-savedmodel-5c8e | tensorflow, performance, cloud, ai | In our [ongoing work](https://dev.to/dchaley/series/27298) running DeepCell on Google Batch, we noted that it takes ~9s to load the model into memory, whereas prediction (the interesting part of loading the model) takes ~3s for a 512x512 image.
The ideal runtime environment is serverless, so we don't have long-lived processes which would load the model once, to predict multiple samples across multiple jobs. Instead, each task instance needs to load the model before doing any work. So, it hurts when the model takes 3x the load time of the actual work… it certainly makes it inefficient to scale horizontally with one short-lived compute node per prediction.
My local machine (a macbook m3 max pro) took ~12 s to load the model, the slowest part of the entire preprocess → predict → postprocess pipeline.
I was curious why it took so long to load the model into memory. It's "only" ~100 MB on disk.
I came across [TensorFlow Performance: Loading Models](https://towardsdatascience.com/tensorflow-performance-loading-models-fb2d0dc340a3) by Libor Vanek. It compares the load times for different formats. Here's the punchline:
I was intrigued 🤞🏻 could we get similar speed-ups just by changing the format?
Yes:
| Environment | SavedModel | HDF5 | Diff |
| -- | -- | -- | -- |
| Macbook M3 Max Pro | 12.3 s | 0.84 s | -11.46 s (-93%) |
| n1-standard-8 w/ 1 T4 GPU | 8.99 s | 2.68 s | -6.31 s (-70%) |
| n1-standard-32 w/ 1 T4 GPU | 8.21s | 2.72 s | -5.49 s (-67%) |
Of note, loading the model into memory used to take ~3x the time of prediction. Now, it's roughly the same.
Converting the model was easy:
```python
# Load the SavedModel version
model = tf.keras.models.load_model("/Users/davidhaley/.keras/models/MultiplexSegmentation")
# Save as HDF5
model.save("MultiplexSegmentation-resaved-20240710.h5")
```
We needed to adjust one factor: the `load_model` call needs an additional parameter to locate custom training objects:
```python
from deepcell.layers.location import Location2D
# [...]
model = tf.keras.models.load_model(
model_path,
custom_objects={"Location2D": Location2D},
)
```
We learned this by importing the HDF5 file without the `custom_objects` and getting the error that `Location2D` wasn't found.
This is the only caveat we've found with the HDF5 format: needing to tell it where to find the custom objects. The prediction results appear to be the same.
70% just by using a different file format! | dchaley |

Whether you're a... | 0 | 2024-07-11T04:00:22 | https://dev.to/thedavidmensah/cloud-computing-a-developers-pov-4b69 | _Hey tech warriors! Today, we’re breaking down the awesomeness of cloud computing. Whether you're a seasoned coder or just dipping your toes in, this guide's got you covered. Let's dive right in!_
**What is Cloud Computing?**
Alright, picture this, "You're working on a project and need more power, like, right now". Cloud computing is your genie in the sky, granting you access to massive computing power, storage, and more all over the internet. No need for bulky hardware or complicated setups. It's like having a tech command centre that's always there when you need it. Awesome, right?
**What does Cloud Computing have to offer, I hear you say?**
Well, it does have quite a number of benefits for certain.
1. **Scalability and Flexibility:** Your Project’s best friend.
Got a project that needs to grow on the fly? With cloud computing, scaling up or down is a easy, fast and simple. Take cloud computing as an expandable suitcase ready to hold as much or as little as you need, whenever you need it.
2. **Cost Efficiency:** Save big bucks Like A Pro
The days where you handle every cost is over. Wave goodbye to those days. In the cloud, you only pay for what you use. It’s like renting a fancy sports car just for the weekend. Fun and economical!
3. **Collaboration:** Just like teamwork, but on Steroids.
Working with a global team? No sweat. The cloud makes it feel like you’re all in the same room. Share code, track versions, and collaborate in real-time. It’s like having a virtual co-working space without the commute.
4. **Disaster Recovery and Backup:** Your data’s guardian angel
Ever lost a whole project to a system crash or hardware failure? I know, that's a nightmare. But with cloud computing, your data is backed up and ready for recovery anytime and anywhere. Just like having a superhero watching over your files 24/7.
5. **Cutting-Edge Tech:** Stay ahead of the curve.
Want to dabble in AI, machine learning, or big data? The cloud has you covered with the latest tools and tech. Cloud computing offers
you a playground filled with the latest and coolest gadgets.
**The Cloud Deployment Models**
1. **Public Cloud:** An All-Access Pass
Think of the public cloud like a giant amusement park. Okay, I promise this is the last Park reference. Providers like AWS, Google Cloud, and Azure offer a range of services that anyone can use. Pay-as-you-go, it’s perfect for anyone from "indie devs" to large enterprises.
2. **Private Cloud:** Your exclusive cloud
A private cloud is like having a VIP section just for your organization. It’s all yours, offering more control and security. Ideal for businesses with specific needs or regulations.
3. **Hybrid Cloud:** Best of both worlds
This model blends public and private clouds, giving you the flexibility to choose where to run your workloads. This model offers a membership to both the VIP club and the main park. Then the power becomes yours to choose each when it makes the most sense.
**The Cloud Service Models**
1. **IaaS (Infrastructure as a Service):** The foundation
You get access to virtualized computing resources over the internet. IaaS is like renting the land to build your tech empire. Think servers, storage, and networking, all ready for you to customize.
2. **PaaS (Platform as a Service):** The builder’s toolkit
PaaS is your fully equipped workshop. It provides a platform allowing you to develop, run, and manage applications without the hassle of infrastructure maintenance. Perfect for focusing on coding and development without getting down in the nitty-gritty of things.
3. **SaaS (Software as a Service):** Ready to use
Need ready to use software? Access software applications over the internet. Think Google Workspace, Salesforce, or Microsoft Office 365. Use them as-is and get straight to work. Working in a fully furnished office.
_Let end here for now, It's 3:27am on a Thursday and I've got to rest._
At a glance, Cloud computing is revolutionizing how we develop software and websites. From its flexible scalability and cost efficiency to its cutting-edge tools and robust security, the cloud is the future. Whether you’re scaling a start-up, managing a large enterprise, or just exploring new tech, the cloud has a solution for you.
And that’s a wrap, tech fam! If this guide sparked some ideas, share it with your fellow developers.
Until next time, happy coding, and may your servers be always up and your downtime minimal!

SFCC Business Manager is highly customizable and allows retailers to personalize it according to their unique requirements. Regardless of whether you operate a small business or a large enterprise, SFCC's Business Manager adapts to meet your specific needs.
In order to use Business Manager, an individual must have access to a B2C Commerce instance. Unfortunately, the Trailhead Playground does not offer B2C Commerce capabilities. If you do not possess access to a B2C Commerce instance, it is advised to inquire with your manager regarding its availability for use.
## Business Manager User Interface
To start using Business Manager, the first step is site selection. The number of sites can vary depending on the size of your company and the number of websites you manage. Once you've made your selection, you will gain access to its data, code, and permissions. However, it's important to note that accessing these requires the necessary access rights, which we will discuss in more detail later in this article.
In B2C Commerce, a site and its code combine to establish a "storefront." This storefront is like a virtual space users experience when they visit your website. It serves as your digital representation. It is important to note that one site can have multiple storefronts for different components of your online presence.
When you click on "Storefront," it will open the selected site in a new window. Additionally, there may be icons visible, such as the Toolkit icon, tailored for developers to troubleshoot issues. One convenient aspect is its automatic integration with the Business Manager site you were recently on, enhancing overall convenience.
## Access Roles in Business Manager
When accessing Salesforce Commerce Cloud, managers can assign three primary roles to various team members.
- **Merchandizers**: They are responsible for managing various aspects of the site's data, such as product management, promotion creation, search preference settings, image handling, and running campaigns.
- **Administrators**: They are responsible for configuring the overall settings of the B2C commerce site. Their role includes making changes to data, managing site data, and implementing new codes.
- **Developers**: In order to debug and troubleshoot problems, as well as configure development-specific settings, developers use Business Manager to directly access the storefront application. These experts are responsible for configuring, debugging, and resolving any issues that may arise.
When considering large retailers, it is common to divide these responsibilities among multiple individuals. Each person takes their specific role and is responsible for their respective tasks. Smaller retailers often face the challenge of having a single person manage multiple access levels while managing various tasks.
To ensure smooth operations, larger retailers often prefer collaborating with dependable partners specialized in Salesforce Commerce Cloud. These partners possess the necessary expertise and teams capable of managing various aspects of their website effectively.
## Learn More About Business Manager
When accessing the Business Manager, two distinct tabs will be visible on the top of your screen: "Merchant Tools" and "Administration." Now, let's delve into further details about each of these tabs.
### Merchant Tools Tab
In the Merchant tab, you will find a comprehensive toolkit that serves as your control center for managing various aspects of your online store. This versatile toolkit empowers you to effortlessly handle settings and data related to your store. From customizing promotional campaigns to managing marketing materials, products, website content, and much more, this all-inclusive toolkit has got you covered.
Inside this toolkit, you will also find an array of useful tools designed to enhance the traffic to your website. Consider them as marketing assets that encompass strategies for optimizing your website's visibility on search engines (also known as SEO techniques). Additionally, these tools enable you to delve into valuable customer data stored externally from the system. It's your ultimate assistant in ensuring seamless management of your online business.
#### Cross-Functional Tools In Merchant Tab
Within the Merchant Tools tab, various versatile tools can be used by various team members to foster collaboration and enhance efficiency in managing online retail operations. Let's explore three notable examples:
- **Reports & Dashboards**: This tool functions as a comprehensive platform for data analysis and visualization. It gathers information from various sources and transforms it into cohesive dashboards, providing valuable insights. These visual representations assist in identifying long-term trends and patterns, facilitating informed decision-making.
- **Page Designer**: It is a sophisticated visual editor that simplifies the creation and management of specialized web pages. Whether it's designing the homepage, crafting lifestyle pages, or developing category landing pages, users can easily create compelling web content without any technical expertise.
- **Content Slots**: It act as versatile code fragments within your storefront. Seamlessly integrated into any part of your website, they serve as dynamic showcases for various elements such as products, categories, multimedia content, or static HTML. Content slots require the collaboration of both merchandisers and developers. Initially, developers are responsible for incorporating code into HTML pages, creating rendering web templates, and uploading the code onto the server. Later, merchandisers utilize Business Manager to generate and schedule the configuration.
### Administration Tab
The second tab, known as Administration, is utilized by administrators and developers. This section allows administrators to handle essential tasks, including:
**-Importing and Exporting Data:** It ensure the smooth transfer of data, seamlessly managing its placement within the site.
**-Managing customer lists and content libraries:** It involves the tasks of tracking customers' purchases and organizing all the content used on a website.
If you are assigned an administrator role, you can configure global settings that apply uniformly to all sites within an organization. These global settings, also known as preferences, involves various aspects such as:
- Regional Settings
- Multiple languages support
- Password limitations
- Time zones
- Orders management
- Customer and sequence numbers, etc.
### Developer Access
Now, let's explore the "Developer Access" level. This group of individuals holds the key to creating and refining the actual online store, known as the storefront. They bring everything together using various tools, with "Business Manager" being their primary tool.
Developers usually work with three windows:
**- Integrated Development Environment (IDE):** In the process of developing and testing applications for a website, an Integrated Development Environment (IDE) is used. This ensures the smooth functioning of the website.
**- Business Manager:** The developers can access and control the storefront site itself through this window.
**- Storefront Application:** Here, developers can effortlessly observe the impact of their code changes on the live website in real-time.
When it comes to the Business Manager Window specifically, developers can perform various essential tasks.
- Build new sites
- Troubleshoot issues.
- Configure code versions
- Manage the website's cache settings for optimal performance
- Handle site taxation
- To help shoppers find what they're looking for, create custom error pages and maintenance pages
Developers also handle various essential tasks required by Business Manager. They ensure the security of systems, monitor system limits (known as quotas) to maintain smooth operations, and oversee the management of user credentials.
### Permissions
In Business Manager, access to different features of the system is determined by job tasks or roles. The administrator holds the most crucial role and is commonly referred to as the "admin." Their responsibility involves overseeing users and permissions.
Here's how it works:
- Setting up the Organization: To set up the organization, the administrator begins by defining all its storefronts and selecting default languages for the system.
- Defining Roles: Roles are created by the admin to assign specific tasks and permissions to team members in the Business Manager. These roles determine the scope of actions each individual can or cannot perform.
Administrators can define roles according to the permissions set for each role.
**- Module Permissions:** It functions like access keys to specific areas, such as the Products and Catalogs section. This allows you to determine who has the ability to modify or update data within those areas.
**- Functional Permissions:** These permissions are comparable to special powers. For instance, granting someone the "Manage_Site_Catalog" permission enables them to add items to the site catalog. This allows you to restrict the actions permitted for different roles.
### Localization
Achieving multilingual functionality is essential in Business Manager. It involves making sure that both the user interface and the underlying data can seamlessly adapt to different languages, enhancing accessibility for a global audience. To accomplish this, the Business Manager provides two distinct ways to configure language settings.
- Firstly, users can customize the appearance of the interface by selecting a preferred language, allowing them to have menus, buttons, and overall display in their desired language while managing product descriptions or content in another language.
- Secondly, users can designate a specific language for working with data within Business Manager. This means they can manipulate product information in one language while viewing it in another.
The administrator plays a key role in determining the language of the interface, while individual users have the flexibility to choose their preferred display language through their profile settings. This multilingual adaptability ensures an inclusive and user-friendly environment for a diverse range of users.
### Personalization
SFCC Business Manager offers the flexibility to customize various elements of the user interface, empowering users to personalize their experience easily. You can customize:

1,919,240 | Unveiling the Dance of Boundaries: Exploring the Immersed Boundary Method (IBM) | Simulating the intricate interplay between fluids and solids presents a significant challenge in... | 0 | 2024-07-11T04:22:20 | https://dev.to/epakconsultant/unveiling-the-dance-of-boundaries-exploring-the-immersed-boundary-method-ibm-2j13 | ibm | Simulating the intricate interplay between fluids and solids presents a significant challenge in computational science. Traditional methods often struggle with complex geometries or require cumbersome meshing techniques. Enter the Immersed Boundary Method (IBM), a powerful tool for modeling fluid-structure interaction, offering a unique approach to tackle these complexities.
What is the Immersed Boundary Method (IBM)?
The IBM bypasses the need for conforming meshes, which adapt to the shape of the solid object within the fluid domain. Instead, it treats the solid object as a collection of massless points or force points embedded within a fixed, background mesh. This allows for remarkable flexibility in simulating objects of arbitrary shapes and complexities.
The Core Idea: Lagrangian vs. Eulerian Framework
Imagine a bustling city. The IBM adopts a combined approach:
- Lagrangian Framework for the Object: The solid object, like a bridge or a swimming fish, is tracked using a Lagrangian framework. This means the object's position and properties are tracked as it moves through the fluid domain.
- Eulerian Framework for the Fluid: The fluid itself is described using an Eulerian framework. This means the fluid properties, like pressure and velocity, are defined at fixed points within the computational domain.
- How Does the IBM Work?
Here's a simplified breakdown of the IBM process:
- Background Mesh Generation: A fixed, uniform mesh is created representing the fluid domain. This mesh doesn't conform to the shape of the solid object.
- Object Representation: The solid object is represented by a set of Lagrangian points or force points distributed throughout its volume.
- Force Calculation: The forces exerted by the fluid on the object are calculated at each Lagrangian point. These forces might involve pressure and viscous forces acting on the object's surface.
- Force Distribution: The calculated forces are then distributed from the Lagrangian points to the surrounding nodes within the fixed mesh using interpolation techniques.
- Fluid Flow Simulation: The fluid flow within the Eulerian mesh is then solved using traditional fluid mechanics equations, taking into account the forces distributed from the object.
- Object Motion Update: Based on the forces acting on the object, its motion and position within the fluid domain are updated for the next time step.
- Iteration: Steps 3 to 6 are repeated iteratively, creating a simulation of the fluid-structure interaction over time.
Benefits and Applications of IBM
1. Flexibility: Simulate objects with complex geometries without the need for intricate mesh generation.
2. Efficiency: Offers a computationally efficient alternative to traditional methods, especially for complex moving objects.
3. Wide Range of Applications: Applicable to various scenarios involving fluid-structure interaction, including:
- Biological Flows: Simulating blood flow within the heart or the movement of microorganisms in fluids.
- Civil Engineering: Analyzing the interaction of water with bridges or other structures.
- Aerospace Engineering: Simulating airflow around aircraft wings with complex shapes.

Have you ever heard of how your cars engine keeps its cool even when the sun beats down relentlessly on it? We can thank the engine cooling system for that! The point is to keep the engine at an ideal temperature, which ensures optimal performance and durability. So, let us bring out the significance of engine cooling systems and how advancement over time in this has had better efficacy.
Why do we need an Engine Cooling System?
In short, an engine cooling system is a complex that was designed to cool the engine depending on its temperature. The system is made up of the radiator, coolant, water pump, thermostat, hoses and fans. Again, it is most important for the engine to be in proper operating temperature (195-220 degrees Fahrenheit). Pistons, valves and cylinder heads are the major engine components that can become damaged if an engine overheats.
New Approaches to Cool Engine Systems
Engine cooling systems have improved considerably over the years to be more efficient and reliable, but there are several key differences in how they function. So, one of the important advancements that we talked about is going to be the variable pairing speed controls with your fans. The fans are able to vary their speed according to the engine temperature, helping save fuel and quiet down. We also have the ability to adjust water pump speed and flow rate with new electric units in some of today's engines, allowing for more precise temperature regulation.
Coolant additives is another breakthrough. The purpose of these additives is to improve the coolant operational performance and protect against corrosion and cavitation (more on that in a moment) within the engine. In addition, some engines use oil coolers to control engine oil temperature. It keeps the oil from thinning out and being overheated, which can lead to engine failure or subpar performance. (Agricultural Machinery)
The Advantages of a Good Engine Reliable Cooling System
A good engine cooling system provides many benefits, like helps better performance of the vehicle and also extends the life of the engine as well an fuel efficiency. A correct thermostat allows the engine to remain at its ideal operating temperature, which can improve fuel mileage. Not only that, but an efficient cooling system will help to regulate the engine heat which can quickly wear out gaskets and seals leading over time (and after thousands of dollars in repair bills) leaks within your motor: another argument for vigilance.
The Care Guide of an Engine Cooling System
To properly maintain and use an engine cooling system, you can check the following steps. Before going to your mechanic, make sure you have a quick peek at the coolant reservoir it is one of those parts in an auto body which if not maintained correctly can result in causing severe damage. Inspect any hoses and the radiator as well for leaks or cracks that can ultimately lead to coolant loss and possible engine overheating. (Water Pump)
Another, but certainly not less important part of the engine cooling system is a regular service. Follow the manufacturer's suggested service intervals - which usually include a coolant system flush, thermostat inspections and water pump assessment. Regular service can avoid these little problems becoming huge issues that result in a large expense for repair work.
The future of engine cooling systems
With the continued progress of technology, we can expect to see engine cooling systems become even better. The use of a new [cooling system], which is free from the conventional coolant dependency, has already crept into hybrid and electric vehicles. This allows movements of the refrigerants to travel more freely around a vehicle if you need it for temperature purposes, instead of utilizing coolant. (Foton Motors)
You see, Last of all an Engine Cooling System is so important for the engine to suitably work well within a car. Engine Cooling systems have been leveraged with time to make them more effective, reliable and safe. This is why regular maintenance and servicing of engine cooling systems keep them in mint shape, which can save you money on expensive repairs while enhancing the performance of your car. Hopefully, the next nuclear fueling solution will come with more efficient and sustainable engine cooling systems. | pwiwyayq_kasjga_de682b3c4 | |

Unlike traditional SQL used for relational databases, Cypher is designed specifically to navigate the relationships within a graph. This article equips you with the basic concepts of Cypher, enabling you to unlock the potential of graph databases.
Understanding the Building Blocks of Cypher
- Nodes: These represent entities within your data, like people, products, or locations. Nodes are visualized as circles and hold properties containing information about the entity.
- Relationships: These depict connections between nodes, signifying the associations they share. Relationships are depicted as arrows and can be directed (one-way) or undirected (two-way). They can also have properties associated with them.
- Patterns: The core concept in Cypher queries, patterns describe the specific structure of nodes and relationships you want to match within the graph.
Constructing Your First Cypher Query
Let's explore a basic Cypher query to find all actors who acted in movies directed by Steven Spielberg:
`Cypher
MATCH (actor:Person {name: "Steven Spielberg"})-[:DIRECTED]->(movie)<-[:ACTED_IN]-(actor)
RETURN actor.name, movie.title`
Breaking Down the Query:
- MATCH Clause: This clause initiates the pattern matching process.
- (actor:Person {name: "Steven Spielberg"}): This defines a pattern matching a node labeled "Person" with the property "name" set to "Steven Spielberg".
- -[:DIRECTED]->(movie): This part of the pattern describes a relationship directed outwards from the "Person" node, labeled ":DIRECTED", leading to another node labeled "movie".
- <-[:ACTED_IN]-(actor): This section defines another relationship directed inwards to the "actor" node, labeled ":ACTED_IN", coming from the "movie" node. Essentially, we're traversing the graph from Steven Spielberg (director) to movies he directed, and then finding actors who acted in those movies.
- RETURN Clause: This clause specifies what information you want to retrieve from the matched nodes. Here, we're returning the "name" of the actor and the "title" of the movie.
Additional Cypher Concepts
As you venture deeper into Cypher, here are some additional concepts to explore:
- Clauses: Cypher offers various clauses beyond MATCH and RETURN, enabling you to filter results (WHERE clause), create new nodes and relationships (CREATE clause), and perform aggregations (COUNT, SUM) on your data.
- Functions: Cypher provides a rich set of functions for manipulating data, like converting strings to uppercase, calculating distances between nodes, or filtering based on specific criteria.
- Subqueries: For complex queries, Cypher allows for nesting subqueries within your main query, enabling you to retrieve data based on multiple conditions.
[The Self Starter Book: Machine Learnings Role in Forecasting Crypto Trends](https://www.amazon.com/dp/B0CP8D7JCN)
Benefits of Using Cypher
- Intuitive Syntax: Cypher utilizes a human-readable syntax that closely resembles natural language, making it easier to learn and understand compared to complex SQL queries.
- Expressive Power: Cypher empowers you to navigate the intricate relationships within your graph data, allowing for powerful queries that wouldn't be feasible with traditional relational databases.
- Declarative Nature: Cypher focuses on what data you want to retrieve, rather than dictating how to retrieve it. This allows the underlying graph database to optimize the execution of your query for efficiency.
Conclusion
Cypher, with its intuitive syntax and expressive power, unlocks the potential of graph databases. By understanding the basic concepts of nodes, relationships, patterns, and core clauses, you can begin crafting queries to extract valuable insights from interconnected data. As you delve deeper, Cypher's advanced features empower you to tackle complex graph-based problems across various domains. So, embark on your Cypher journey and start exploring the fascinating world of graph data!

1,919,243 | Why Programmers Shouldn’t Be A Freelancer | It’s better to quit if you can. There are so many benefits to being an employee. Protected... | 0 | 2024-07-11T04:29:10 | https://dev.to/manojgohel/why-programmers-shouldnt-be-a-freelancer-mj4 | freelance, webdev, beginners, react | It’s better to quit if you can. There are so many benefits to being an employee.
## **Protected by labor laws**
If you enter into a contract (especially a contract for work) as a freelancer, no one will protect you, even if you end up working huge amounts of time. Ultimately, you are responsible for your own death from overwork.
In contrast, company employees are protected by a very powerful law called labor laws. Although it is lax in other places, overtime is illegal, and there are limits on working hours. If the terms of your contract with a company do not comply with the Labor Standards Act, the contract itself can be invalidated. That is how powerful labor laws are.
## **There are great financial benefits.**
For example, if you want to study for your job, your company may cover the cost of specialized books and paid courses. Some companies also pay for welcome parties, and some even subsidize rent. Depending on the company, the monthly health insurance premium may be capped at $200-$300.
In addition to the amount you pay for yourself, the company also pays the same amount for employees’ pension insurance, so on average, you can receive more than twice the amount of the national pension, depending on your income. There are many direct financial benefits like this.
## **Even if you lose your job**
There is an item for “employment insurance” on your pay slip, right? If you are enrolled in this, even if the company goes bankrupt tomorrow, or if you are laid off due to personnel reductions, unemployment insurance will be paid immediately if it is due to company circumstances (there are conditions such as a waiting period of several days, enrollment in employment insurance for more than six months, and job hunting).
If the company goes bankrupt due to unpaid wages, you can also use the accuracy of the government guarantee. However, freelancers usually do not have such a safety net. If you lose your job, your income is $0. You are essentially a NEET. You will always be fighting this fear, so if you are mentally weak, I recommend that you stay as a company employee. If you are an employee, you will receive a salary just by sitting.
## **Social trust is enormous**
Unless **y**ou have a very well-known track record, it is safe to say that you have almost no social trust. For example, there are the following specific disadvantages.
- It is more difficult to apply for a credit card or take out a loan compared to when you are an employee (basically you apply for a credit card while you are still an employee)
- It becomes harder to pass the screening process when renting a room.
It can also cause problems in business. For example, when trying to make an appointment with a company, if you are an employee, you are seen as a member of that organization, so if it is a first-section listed company or a group company, you can make as many appointments as you like. It may sound bad, but you can use the company’s trust as your own.
However, if you become an individual, you must prepare to be turned away unless you know them. Being treated like this can be quite mentally tough.
## **There are almost no tasks other than your main job**
In a company with a certain number of employees, roles are divided and there are specialists in each field. However, the moment you become freelance, you will be responsible for all of them.
Of course, you can outsource, but you can’t do without studying at all. If you want to enter into a contract or do any commercial activity, you need legal knowledge, and you need to file a tax return at least once a year, so accounting and financial knowledge is also essential.
Freelancers are “managers,” so if you are not good at finance or numbers, you tend to get into a difficult situation. You will also be given general affairs work. Even if you become independent in a position other than sales, you will need to do a minimum amount of sales activity.
There are many people who want to concentrate on their main job but are not allowed to do so, or who are not suited to these jobs, so they quit freelancing and return to being a salaried employee.
## **Why do people become freelancers**
So why do people give up these enormous benefits to become freelancers? It is said that there are two main types, and most people would fall into one of the following categories.
- You have a proven track record and advanced skills, so you can expect to receive a very high salary.
- I am not suited to being an employee (in an organization) and have no choice but to live as a freelancer.
By the way, I’m a social misfit so I’d say it’s more the latter lol ＼(^o^)
Back to the point.
If you consider yourself to be the former, I think it’s a good idea to take the risks mentioned above and become independent. You only live once. It’s very meaningful to take on challenges so that you don’t have any regrets, and if you’re lucky, you can expect a return that’s commensurate with your efforts.
In the latter case, the most difficult thing is where to get work from. It is necessary to get it continuously, not one-off. Recently, there are companies that will introduce you to projects, but they charge a 30–40% “commission” and in many cases you will work at the client’s site. It’s the worst.
If you can only get work from these places, you will end up taking a lot of risks even though the environment and treatment are not that different from that of a company employee. In other words, technical ability is important, but sales ability and communication skills to get work are also extremely important.
So, whether you choose the former or the latter, the golden pattern for going independent is to build up a track record and connections while working for a company. You need both, not just one. It’s also effective to start a side business little by little while you’re still working for a company.
Recently, there’s been a trend towards lifting the ban on side jobs, so this
might be a good time. It would be great if you could go independent when your side business is on track and you’re sure you can make a living even if you quit your job.
Why do you want to become a freelancer? Why do you need to become one? Do you have the achievements and skills to be able to live as a freelancer, and even more so, the communication skills?
It’s up to each individual to decide based on their own circumstances. You don’t necessarily have to become a freelancer. If you feel that the things I’ve mentioned so far are difficult, I think you’d be happier working as a company employee. | manojgohel |

Imagine a web of connections, where dots represent entities and lines depict their associations. This is the essence of graphs, offering a powerful tool to model and analyze interconnected systems in diverse fields.
The Building Blocks of Graphs
- Vertices (Nodes): These are the fundamental units of a graph, represented as dots or circles. Vertices can represent anything from people in a social network to cities connected by roads.
- Edges: These are the lines or connections between vertices, signifying the relationships they share. Edges can be directed (one-way arrows) indicating a specific direction to the relationship, or undirected (lines) representing a mutual connection.
- Labeled vs. Unlabeled: Vertices and edges can be labeled with additional information. For example, a social network graph might have vertices labeled with names and edges labeled with "friends.
Types of Graphs
- The world of graphs extends beyond the basic structure. Here are some common graph types:
- Simple Graph: The most basic type, with no loops (edges connecting a vertex to itself) and no multiple edges between the same pair of vertices.
- Complete Graph: Every vertex is connected to every other vertex by an edge.
- Directed Acyclic Graph (DAG): Edges have a direction, and there are no cycles (a path that starts and ends at the same vertex).
- Weighted Graph: Edges have weights associated with them, representing a value or cost associated with the connection.
Graph Terminology
As you delve into graph theory, you'll encounter specific terms:
- Degree of a Vertex: The number of edges connected to a vertex.
- Path: A sequence of connected edges leading from one vertex to another.
- Cycle: A closed path that starts and ends at the same vertex.
- Connected Graph: A graph where a path exists between every pair of vertices.
- Isomorphic Graphs: Graphs with the same structure, even if the labels of vertices or edges differ.
Applications of Graph Theory
- Graph theory transcends the realm of mathematics, finding applications in various domains:
- Social Network Analysis: Modeling social networks to understand user interactions and information flow.
- Computer Science: Designing algorithms for routing, network optimization, and search engines.
- Logistics and Transportation: Optimizing delivery routes and transportation networks.
- Project Management: Scheduling tasks and identifying dependencies between project activities.
- Biology: Modeling protein-protein interactions or metabolic pathways within a cell.
The Power of Abstraction
The beauty of graph theory lies in its ability to capture the essence of relationships, providing a powerful tool for abstraction. By focusing on connections rather than specific details, we can model complex systems and gain valuable insights.

> (NOTE: First published in my Substack list: https://andresalvareziglesias.substack.com/)
## List of chapters
- Chapter 1 - The All-in-one solution for Auth in Django
- **Chapter 2 - How to install and configure Django AllAuth** ←This one!
- Chapter 3 - Social login with Django AllAuth
- Chapter 4 - Customizing Django AllAuth UI
- Chapter 5 - Extending Django AllAuth user model with custom fields
## Installation of AllAuth
As any other Django extension, AllAuth installation has two parts: install the python dependencies and configure the Django app settings file. To make things more fun, we will use (and learn) Google Project IDX, a wonderful cloud IDE and development platform.
First, log into IDX and create a new Django based project:
Once created, we will have a fully working Django app, so move on!
The installation of AllAuth itself is simple: just install the django-allauth python package. Project IDX (and ourselves, in case of manual project creation) creates a `requirements.txt` file, so let's use it:
- Add "**django-allauth**" to `dependencies.txt`. You can also add "**django-allauth[socialaccount]**", used in the next chapter for social login
- Open the IDX terminal and navigate to `dependencies.txt` parent folder
- Load the virtual environment created with out project by IDX: `source ~/allauth-test/.venv/bin/activate`
- Execute: `pip install -r requirements.txt`
Now, we need to make some changes to the main Django app settings file. Open settings.py and locate the TEMPLATES setting. Add the AllAuth required processor:
```
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
# This one
'django.template.context_processors.request',
],
},
},
]
```
Then, locate the `AUTHENTICATION_BACKENDS` setting and add the AllAuth backend. If not present, add it now:
```
AUTHENTICATION_BACKENDS = [
# Needed to login by user in admin, regardless of `allauth`
'django.contrib.auth.backends.ModelBackend',
# This one
'allauth.account.auth_backends.AuthenticationBackend',
]
```
Next, add AllAuth to installed apps as any other Django extension. You can also add the social login extensions here, used in the next chapter:
```
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
# Add these
'allauth',
'allauth.account',
'allauth.socialaccount',
'allauth.socialaccount.providers.google',
]
```
The last modification of the settings file is the required middleware. Locate the `MIDDLEWARE` section and add the AllAuth middleware at the end:
```
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
# This one
"allauth.account.middleware.AccountMiddleware",
]
```
AllAuth has it own views, templates and databases, so we need to perform some extra actions. The first action is to define the URLs for AllAuth views. Open the main `urls.py` and add them:
```
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('accounts/', include('allauth.urls')),
]
```
Now, the code modifications are completed, but we need to create AllAuth required tables. Use the Django migration tool from the IDX terminal, navigating to `manage.py` location and executing:
```
python3 manage.py migrate
```
We also need an administrator to test the login (and to create users). Create it now:
```
python3 manage.py createsuperuser
```
## Testing AllAuth installation
Now, we have a fully working AllAuth installation. To test the authentication methods, create a demo app with `manage.py`:
```
python3 manage.py startapp demo
```
Register it in the `INSTALLED_APPS` section of the main settings page:
```
INSTALLED_APPS = [
(...)
'allauth',
'allauth.account',
'allauth.socialaccount',
'allauth.socialaccount.providers.google',
# This one
'demo'
]
```
And map it to main `urls.py` file:
```
urlpatterns = [
path('', include('demo.urls')),
path('admin/', admin.site.urls),
path('accounts/', include('allauth.urls')),
]
```
Then, create a simple view in our new demo app:
```
from django.shortcuts import render
from django.http import HttpResponse
def indexView(request):
if request.user.is_authenticated:
return HttpResponse("""
<span style='color: green;'>Logged in</span>
""")
else:
return HttpResponse("""
<span style='color: red;'>Not logged in</span>
""")
```
And map it to demo's urls.py:
```
from django.contrib import admin
from django.urls import path, include
from demo.views import indexView
urlpatterns = [
path('', indexView, name='indexView'),
# Override default postlogin action with our view
path('accounts/profile/', indexView, name='profileOverridenView'),
]
```
And now, load the page in IDX’s viewer:
We can use now AllAuth views to perform authentication. For example, use /accounts/login endpoint to perform a login with the previously created user:
And then, we will receive the expected login page:
You can also use other useful AllAuth views, like:
- Signup: `/accounts/signup/`
- Login: `/accounts/login/`
- Logout: `/accounts/logout/`
- Change password: `/accounts/password/change/`
Simple and easy!

In the last post we have talked about interfaces of DOM. In this post we are going to discuss about JSON.
So let's get started🔥
## What is JavaScript JSON?
JSON stands for **J**ava**S**cript **O**bject **N**otation. It is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. In simple words we can say that it is a text format for storing and transporting data.
Example -:
Here we have an object with three properties.
JSON is used to send data between computers.
JSON is built on two structures:
1. A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array.
2. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence.
## Why JSON?
We know that whenever we declare a variable and assign a value to it, it’s not the variable that holds the value but rather the variable just holds an address in the memory where the initialized value is stored.
Suppose we have `var age=22` so here age holds the memory location where 22 is stored. Now suppose you have to transfer data now what you will do is you will give your computer memory in order to transfer data because your data is stored in memory and you don't have any other way apart from it. But giving away complete memory is risky and problematic. So how can we transfer the data🤔.
This problem is resolved by JSON. JSON serializes the data and converts it into a human-readable and understandable format, which also makes it transferal and to be able to communicate.
In summary, JSON solves the data transfer problem by converting data into a standardized, text-based format that is easily transferable between systems and across different platforms. This ensures that data can be accurately and efficiently communicated without relying on machine-specific memory representations.
## Advantages of JSON
1. Human-Readable: JSON is easy for humans to read and write.
2. Interoperable: JSON is language-independent but uses conventions that are familiar to programmers of the C family of languages (including C, C++, C#, Java, JavaScript, Perl, Python, and many others).
3. Lightweight: JSON is less verbose than XML, making it a more efficient format for data interchange.
4. Easy to Parse: JSON can be easily parsed by machines, and most programming languages provide libraries or functions to parse and generate JSON.
## JSON Syntax Rules
JSON syntax is derived from JavaScript object notation syntax:
- Data is in name/value pairs. Example -: `"name:"Akshat"`
- Data is separated by commas. Example -: `"name:"Akshat", "age":22`
- Curly braces hold objects. Example -: `let details={"name:"Akshat", "age":22}`
- Square brackets hold arrays. Example -: `let details={"name:"Akshat", "age":22,"ids":[12345,6678]}`
**JSON Objects**
A JSON object is a collection of key/value pairs. The keys are strings, and the values can be strings, numbers, objects, arrays, true, false, or null.
**JSON Arrays**
A JSON array is an ordered collection of values. The values can be strings, numbers, objects, arrays, true, false, or null.
Here we have an object that holds an array `Avengers` in which each value is detail object of an avenger.
To access name of first avenger-:
`Avengers[0].Name`
The file type for JSON files is ".json".
## Convert a JSON Text to a JavaScript Object
We will be using the `JSON.parse()` method to convert the JSON text to a JavaScript Object.
When using the `JSON.parse()` on a JSON derived from an array, the method will return a JavaScript array, instead of a JavaScript object.
Date objects are not allowed in JSON.If you need to include a date, write it as a string.
Functions are not allowed in JSON.If you need to include a function, write it as a string.
## JSON.stringify()
Convert a JavaScript object into a string with `JSON.stringify()`.
## Storing Data
JSON makes it possible to store JavaScript objects as text.
The `localStorage.setItem()` method is used to store this JSON string in the browser's local storage with the key "testJSON". This allows the data to persist across browser sessions.
To retrieve the stored data, the `localStorage.getItem()` method is called with the key "testJSON", returning the JSON string previously stored. This string is then parsed back into a JavaScript object using the `JSON.parse()` method, and the resulting object is assigned to the variable obj.
So this is it for this blog I hope you have understood it well. Please feel free to add if I have missed something.
Don't forget to follow me.

1,919,250 | Exploring the Future of Data Operations with LLMOps | Introduction In the rapidly evolving world of technology, the way we handle data is... | 0 | 2024-07-11T04:43:23 | https://dev.to/supratipb/exploring-the-future-of-data-operations-with-llmops-41hc | machinelearning, ai, data, aws |
## Introduction
In the rapidly evolving world of technology, the way we handle data is undergoing significant changes. One of the most exciting developments in this area is the emergence of Large Language Models Operations (LLMOps). LLMOps is a field that combines the power of Large Language Models (LLMs) with data operations to create more efficient, intelligent, and scalable solutions.
## What is LLMOps?
Large Language Models Operations (LLMOps) is about the methods and steps taken to use, control, and improve big AI models that deal with a lot of data. These AI models, like GPT (Generative Pre-trained Transformer), can read and create text that sounds like a human wrote it based on what they are fed. LLMOps aims to use these models to better handle data, analyze it, and make decisions.
So, [what is LLMOps](https://lakefs.io/blog/llmops/) in simple terms? It's the process of making big AI models work better for us. By managing these models wisely, we can process huge amounts of data more efficiently, make smarter decisions, and save time. This makes LLMOps a crucial part of working with AI in today's data-driven world.
## Benefits of LLMOps
LLMOps brings a fresh perspective to handling and analyzing data. It steps beyond traditional methods, introducing efficiencies that can reshape how businesses view their data operations. Let's break down its core benefits a bit further to understand the impact better:
### Boosted Efficiency
Efficiency is a big plus of LLMOps. It makes analyzing and processing data much quicker by automating these tasks. Now, tasks that used to take a lot of time are done much faster. LLMOps handles the repetitive and tough tasks, letting people work on more important things. For instance, it can automatically summarize information, sort data, and find important points. This way, useful insights are found quicker, allowing companies to make smart decisions faster than before.
### Unmatched Scalability
Scalability with LLMOps is a game changer. Usually, traditional data tasks struggle when there's more data, needing extra resources or time to keep up. But LLMOps, using big language models, easily deals with increasing data. As data grows, LLMOps can handle more without needing a lot more resources. This ability means companies can look after their data well, keeping them flexible and quick to respond.
### Improved Accuracy
Accuracy in data operations is crucial for reliable insights and predictions. LLMOps enhances this aspect by leveraging models trained on extensive datasets. These models bring a level of precision to data analysis that manual processes or traditional methods can't match. They learn from the data they process, continually improving their accuracy over time. This ability to refine insights makes LLMOps invaluable for making predictions, understanding customer sentiment, and driving data-driven decision-making. With more accurate analysis, organizations can trust the insights they gather, leading to better outcomes.
## How Does LLMOps Work?
LLMOps is about using a set of technical steps to handle big language models well. Below, we explain the basic steps and main parts that make LLMOps work, aiming for simple and clear explanations:
### Data Collection and Preparation
The first step in LLMOps is gathering and preparing the data. This involves collecting the raw data from various sources and then [cleaning the data](https://www.techtarget.com/searchdatamanagement/definition/data-scrubbing). Cleaning may include removing errors, filling in missing values, or formatting the data so that it's consistent. This step ensures the data is ready and in the right format for the model to process.
```python
import pandas as pd
# Sample data loading
data = pd.read_csv('sample_data.csv')
# Dropping missing values
cleaned_data = data.dropna()
# Saving the cleaned data
cleaned_data.to_csv('cleaned_data.csv', index=False)
```
### Model Selection
Next, a suitable large language model is chosen based on the task at hand. The selection depends on factors like the size of the data, the complexity of the task, and the specific requirements of the operation, such as whether the task involves understanding language, generating text, or analyzing sentiments.
This code demonstrates the initialization of a GPT-2 model, which is a type of large language model, using the transformers library. First, it creates a configuration for the model with GPT2Config(). Then, it initializes the model itself with this configuration. This step is crucial for setting up the model before training it with specific data.
```python
from transformers import GPT2Model, GPT2Config
# Initializing a GPT-2 configuration
model_config = GPT2Config()
# Instantiating a GPT-2 model from the configuration
model = GPT2Model(config=model_config)
```
### Model Training or Fine-Tuning
Although many large language models come pre-trained on vast datasets, they often require fine-tuning to perform specific tasks effectively. This step involves [training the model](https://docs.aws.amazon.com/machine-learning/latest/dg/training-ml-models.html) further on a dataset specific to the task. The goal is to adjust the model's parameters so it can understand the nuances of the new data and perform the desired operations with higher accuracy.
This example sets up the environment for fine-tuning a model on a custom dataset. It specifies training arguments like the number of epochs, batch size, and logging directory. Fine-tuning adjusts the model to perform better on specific types of data or tasks by training on a dataset that's closely related to the target application.
```python
# This is a simplified example. Real-life fine-tuning involves more steps.
from transformers import TrainingArguments, Trainer
training_args = TrainingArguments(
output_dir="./models",
num_train_epochs=3,
per_device_train_batch_size=4,
per_device_eval_batch_size=4,
warmup_steps=500,
weight_decay=0.01,
logging_dir="./logs",
)
trainer = Trainer(
model=model,
args=training_args,
train_dataset=custom_training_dataset,
eval_dataset=custom_validation_dataset,
)
trainer.train()
```
### Deployment
Once the model is fine-tuned, it is deployed into a production environment where it can start processing real data. Deployment involves integrating the model into existing data operation workflows, ensuring it can receive data input, process it, and then output the results in a useful format.
This example demonstrates using a text generation pipeline with a GPT-2 model to generate text based on a given prompt. It's an example of how LLMOps can produce insights or content by inputting prompts or questions into a model, which then generates relevant and insightful responses. This process is vital for automating content creation, summarization, or even generating predictive text for decision-making.
```python
from transformers import pipeline
# Initializing the pipeline for text generation
text_generator = pipeline("text-generation", model="gpt2")
# Generating text based on a prompt
generated_text = text_generator("The future of AI in ", max_length=50)
print(generated_text[0]['generated_text'])
```
## How LLMOps is Transforming Data Operations
The introduction of Large Language Models Operations (LLMOps) is indeed revolutionizing how we manage and interpret data. Beyond automating content generation, enhancing data analysis, and improving decision making, LLMOps is paving the way for several other transformative changes in data operations.
### Streamlined Data Integration
LLMOps simplifies the process of integrating diverse [data sources](https://www.ibm.com/docs/en/atlas-policy-suite/6.0.3?topic=suite-data-source-definitions). It can efficiently combine information from various formats and systems, making it easier for organizations to get a comprehensive view of their data. This streamlined integration ensures that data is more accessible and usable for analysis.
### Real-time Data Processing
LLMOps enables real-time processing of data. This means that as soon as data is created or collected, it can be analyzed and acted upon. This immediate processing capability allows businesses to respond to changes and make decisions with the most current information available.
### Enhanced Security Measures
With LLMOps, there is a stronger emphasis on data security. As these systems process vast amounts of sensitive information, they are designed with advanced security protocols to protect against unauthorized access and cyber threats. This ensures that data remains safe throughout its lifecycle.
### Customizable Operations
LLMOps offers customizable operations tailored to the specific needs of a business or project. Organizations can adjust how data is collected, analyzed, and reported to fit their unique requirements. This flexibility ensures that LLMOps can be effectively utilized across various industries and for different purposes.
## Conclusion
LLMOps marks a big step forward in data operations. It uses large language models to improve how we analyze data, making it faster, more scalable, and more precise. As technology gets better, LLMOps will grow too, offering new opportunities for businesses and organizations in different areas. The future of data operations with LLMOps isn't just something to look forward to; it's happening now and changing things in exciting ways.

1,919,251 | The OP Stack Factor: Powering Ethereum’s Leap Towards 2.0 | As we know, the top selling point for any Layer2 rollup framework (be it for optimistic or... | 0 | 2024-07-11T04:43:50 | https://www.zeeve.io/blog/the-op-stack-factor-powering-ethereums-leap-towards-2-0/ | ethereum, opstack, rollups | <p>As we know, the top selling point for any Layer2 rollup framework (be it for optimistic or zero-knowledge technology) is Ethereum-compatibility along with the ability of L2 chains to settle on Ethereum to inherit its high-staked security, decentralization, and liquidity. Let’s talk about one such most-suited and ready L2 rollup framework; OP Stack in this article. First, we will discuss the rollup-specific vision of the Ethereum 2.0 ecosystem and then the value proposition of the OP stack framework in putting Ethereum in steroid. </p>
<h2 class="wp-block-heading" id="h-spotlighting-ethereum-2-0-and-its-rollup-centric-vision-nbsp">Spotlighting Ethereum 2.0 and its rollup-centric vision </h2>
<p>Ethereum 2.0 or ETH2 presents next-generation upgrades on the Ethereum protocol. It entails notable changes such as:</p>
<li>Transitioning the network from proof-of-work (PoW) to proof-of-stake consensus. This has allowed the network to be secured by validators instead of miners, which will obviously reduce the energy requirement while also making the ecosystem highly resilient.</li>
<li>Introducing a whole new structure for L2 chains running on Ethereum. It includes a beacon chain that interacts with all other chains through several ‘shards’ or the sharded blockchains. This approach of breaking down the network in shards and allowing parallel transaction execution, <a href="https://www.zeeve.io/blockchain-protocols/deploy-ethereum-blockchain/">Ethereum</a> has increased the network throughput and capacity of its network significantly. </li>
<p>That’s all about Ethereum 2.0’s features; now let’s talk about its rollup-centric aspect. Ethereum researchers already predicted the rollups revolution back in 2019 and therefore Ethereum’s co-founder Vitelik Buterin called rollups< as the end game for blockchain scalability. Considering this, Ethereum made some modifications to its roadmap. With 2.0 upgrade, Ethereum’s initially planned that Ethereum as a full-fledged blockchain will cater to the scalability requirements and all the L2 chains will achieve unprecedented scalability through various shards. </p>
<figure class="wp-block-image aligncenter size-large"><a href="https://www.zeeve.io/talk-to-an-expert/"><img src="https://www.zeeve.io/wp-content/uploads/2024/07/Launch-Ethereum-L2s-with-Zeeves-Comprehensive-RaaS-Stack-1-1024x213.jpg" alt="OP STack Powering Ethereum 2.0 " class="wp-image-71617"/></a></figure>
<p>Later, seeing the innovative rollups’ concept and its tremendous growth, Ethereum decided that transactions from end users will be computed on the L2 rollup chain, not Ethereum. However, final execution and validation will be carried out on L1 Ethereum. Using sharding, Ethereum had the aim to achieve 3000 TPS, but rollups + sharding can allow Ethereum to achieve up to 1,00,000 TPS. Due to this, most of today’s rollup frameworks like Polygon CDK, Arbitrum Orbit, Zk stack Hyperchain, and <a href="https://www.zeeve.io/appchains/optimistic-rollups/">OP Stack</a> allow L2s to use EThereum as their base layer and all of them focus on maintaining EVM compatibility. </p>
<h2 class="wp-block-heading" id="h-how-op-stack-is-adding-value-to-the-ethereum-ecosystem">How OP Stack is adding value to the Ethereum ecosystem?</h2>
<p>As we discussed, OP Stack is the most Ethereum-aligned rollup framework. Thus, it focuses more on L2 development. If we look at the numbers, OP Stack currently has<a href="https://l2beat.com/scaling/summary?#layer2s"> 26 live chains</a>, out of which just 2 are built as Layer3 and the rest 24 are L2s. Similarly, if we talk about another popular optimistic rollup; Arbitrum orbit– it has<a href="https://l2beat.com/scaling/summary?#layer2s"> 21</a> live chains out of which 9 are Layer2s and 12 are Layer 3s. This analysis highlights the fact that OP Stack is more into favor of L2s choosing Ethereum as their base layer, instead of OP mainnet. However, OP stack has recently announced their support for L3s superchains. </p>
<p>The demand for OP Stack Layer2s have even increased upon arrival of ‘Fault Proofs’ and Stage 1 upgrade. You may know that, permissionless fault proof systems allow OP Stack chains to enable ETH and ERC-20 withdrawal in a purely permissionless manner while Stage 1 transitions OP rollups to be governed through smart contracts. All these updates make the OP Stack ecosystem a lot more mature and secure at the same time. </p>
<p>Now that we know about the OP Stack framework adding value to Ethereum 2.0, let’s also dive a little deeper into these values. This will give you a comprehensive view of what main benefits OP Stack L2s can drive to its base Layer1 ecosystem:</p>
<h3 class="wp-block-heading" id="h-1-accelerating-ethereum-s-revenue-through-gas-fee-da-cost-and-more">1- Accelerating Ethereum’s revenue through gas fee, DA cost, and more:</h3>
<p>In Q1: 2024,<strong> </strong>Ethereum revenue was recorded at a whopping <a href="https://thedefireport.io/">$365 million in Q1, 2024</a> while Ethereum’s fee has seen an increase of 58% since 2017. OP Stack, being a highly Ethereum-aligned framework, also contributes to this profit considerably. If we look at the very recent data from Token Terminal, it mentions that $7B+ value has been bridged from Ethereum Layer1 to the OP stack superchains (between July21 to Apr, 24). Additionally, each OP Stack chain within the superhains ecosystem contributes to more than 2.5% of Layer2 revenue and 15% of the gross profit of the Optimism. For such a huge transaction, Ethereum definitely makes a good amount of revenue as transaction or gas fee. </p>
<figure class="wp-block-embed aligncenter is-type-rich is-provider-twitter wp-block-embed-twitter"><div class="wp-block-embed__wrapper">
https://twitter.com/tokenterminal/status/1806793569530728585
</div></figure>
<p>Likewise, Ethereum also receives DA fees from OP Stack using Ethereum DA for seamless data availability. Here, OP Stack L2s have the option to store data on-chain as ‘calldata’ or post them as blobs using EIP-4844 for cheaper storage. For both the instances, chains need to incur certain DA cost for data storage and 100% availability. For example, calldata on Ethereum Layer1 currently costs around $26.22. Another main source of revenue is sequencing for MEV that we've discussed separately below. </p>
<h3 class="wp-block-heading" id="h-2-leveraging-ethereum-s-pos-consensus-for-l2s">2- Leveraging Ethereum’s PoS consensus for L2s:</h3>
<p>By allowing L2 rollup chains to use Ethereum as the settlement layer, OP Stack maximizes the growth of its PoS consensus in addition to ecosystem growth, and eventually the revenue. For example, if an OP Stack L2 leverages Ethereum’s PoS consensus on Ethereum to secure its network, it will require adding more validators on Layer1 and thus increased staking from them. Hence, if more L2 solutions use Ethereum as base layer, it will lead to more ETH being staked and thereby increase in network’s overall profit.</p>
<h3 class="wp-block-heading" id="h-3-offering-ethereum-mev-system-to-l2-rollups-nbsp">3- Offering Ethereum MEV system to L2 rollups : </h3>
<p>One of the critical challenges of OP stack structure is the centralization of sequencer which could lead to bad MEV such as front-running attacks even more after the 2-second block production of Bedrock upgrade. To overcome this, OP Stack allows L2 to become L1-sequenced and opt for decentralization to protect MEV. L2 rollups can reuse the Ethereum’s searcher-builder-proposer naturally and thus assign the accountability of performing MEV to the block builders on L1. MEV is right now one of the main USPs of Ethereum, which makes a way for a really good revenue stream for Ethereum validators as the opportunities does not come across any middleman, instead it is entirely captured by the block proposers.</p>
<h3 class="wp-block-heading" id="h-4-onboarding-more-web3-users-with-easily-scalable-l2s-nbsp">4- Onboarding more web3 users with easily scalable L2s: </h3>
<p>In the past few years, we have seen several projects (L1 and L2s) migrating over a rollup-based ecosystem with the OP stack. A recent example is Cero, which is migrating to Ethereum L2 built with OP Stack from its L1 blockchain. A common reason for migration in all these projects is the ease of scaling which allows chains to onboarding millions or even billions of web3 users seamlessly. DeFi and web3 gaming chains often need to scale to cater to the massive traffic on their dApps, but doing this is still a challenge with Ethereum due to lack of modularity and high congestion. OP stack solves this through its modular architecture where L2 chains can adjust the scalability as per the traffic. This way, OP Stack allows Ethereum L2s to scale endlessly and onboard web3 users without any challenges.</p>
<h3 class="wp-block-heading" id="h-5-making-ethereum-tools-and-resources-widely-accessible">5- Making Ethereum tools and resources widely accessible: </h3>
<p>Post-bedrock upgrade, OP Stack has geared up to become even more aligned towards Ethereum and hence it allows OP Stack developers a fully Ethereum-equivalent experience by making Ethereum’s codebase, comprehensive tools, frameworks, and resources available for them. This increases the usability of Ethereum tools and introduces them to the global web3 community, driving direct value to Ethereum. </p>
<h2 class="wp-block-heading" id="h-launch-your-ethereum-l2-with-op-stack-using-zeeve-raas-nbsp">Launch your Ethereum L2 with OP Stack using Zeeve RaaS </h2>
<p>Here, our analysis of OP Stack & Ethereum 2.0 concludes. We have seen the whole concept about how the OP stack framework is adding value to Ethereum and why OP Stack chains are one of the preferred options for web3 projects.

Unlike acquisition marketing, which seeks to attract new customers, customer marketing leverages the potential of the current customer base. For app developers in NYC, this approach can significantly impact retention rates and customer lifetime value.
**Key Components of a Customer Marketing Framework**
**1. Customer Segmentation**
Segmenting customers based on demographics, behavior, and purchase history is crucial for delivering personalized marketing messages. Effective segmentation allows businesses to tailor their marketing efforts to specific groups, enhancing relevance and engagement.
**2. Customer Journey Mapping**
Understanding the customer journey from initial contact to post-purchase interactions helps businesses identify key touchpoints and pain points. Mapping the customer journey enables companies to optimize each stage, ensuring a seamless and positive experience. For [app developers NYC](https://www.nimblechapps.com/services/android-app-development-company), understanding local market nuances can enhance these journey maps.
**3. Personalization and Customization
**Personalized marketing campaigns resonate more with customers, fostering a sense of connection and loyalty. Utilize customer data to deliver customized content, offers, and recommendations that cater to individual preferences and needs.
**4. Content Marketing**
High-quality, relevant content is essential for engaging customers and providing value. Develop a content strategy that addresses customer pain points, answers their questions, and educates them about your products or services. Content marketing can include blogs, videos, webinars, and social media posts. [App developers NYC](https://www.nimblechapps.com/services/android-app-development-company) can leverage their tech expertise to create compelling, industry-specific content.
**5. Customer Feedback and Surveys**
Collecting and analyzing customer feedback is vital for understanding their needs and improving your offerings. Regular surveys and feedback loops help identify areas for enhancement and show customers that their opinions matter.
**6. Loyalty Programs**
Implementing loyalty programs rewards customers for their continued patronage. These programs can include points systems, exclusive discounts, and special offers. Loyalty programs incentivize repeat purchases and strengthen customer relationships.
**7. Referral Programs**
Encourage satisfied customers to refer friends and family by offering incentives such as discounts or rewards. Referral programs tap into the power of word-of-mouth marketing, bringing in new customers through trusted recommendations. App developers in NYC can benefit from a well-structured referral program, leveraging the city's extensive professional networks.
**8. Marketing Automation**
Leverage marketing automation tools to streamline and scale your customer marketing efforts. Automation allows for timely, personalized communication based on customer behavior and preferences, ensuring consistent engagement without manual intervention.
**Implementing the Customer Marketing Framework**
**1. Define Clear Goals**
Set specific, measurable goals for your customer marketing efforts. These goals can include increasing customer retention rates, boosting average order value, or enhancing customer satisfaction scores.
**2. Leverage Customer Data**
Collect and analyze customer data to gain insights into their behavior, preferences, and needs. Utilize this data to inform your segmentation, personalization, and content strategies.
**3. Develop a Comprehensive Plan**
Create a detailed plan that outlines your customer marketing initiatives, timelines, and key performance indicators (KPIs). Ensure that all team members understand their roles and responsibilities.
**4. Execute and Monitor**
Implement your customer marketing strategies and monitor their performance regularly. Use analytics tools to track progress and identify areas for improvement.
**5. Iterate and Improve**
Customer marketing is an ongoing process. Continuously gather feedback, analyze results, and refine your strategies to ensure they remain effective and aligned with customer needs.
**Conclusion**
A well-structured customer marketing framework is essential for fostering strong, long-lasting relationships with your customers. By focusing on segmentation, personalization, content marketing, and leveraging customer data, businesses can enhance customer satisfaction, drive repeat purchases, and encourage brand advocacy. Implementing and refining a customer marketing framework will ultimately lead to sustained success and growth in today's competitive market. This is particularly true for app developers in NYC, where a targeted and strategic approach can set you apart in a crowded and dynamic industry.

```json
"lint-staged": {
"*.{js,jsx,ts,tsx}": [
"eslint --fix --max-warnings=0", // both errors and warnings must be fixed
// "eslint --fix" // errors must be fixed but warnings can be ignored
"prettier --write"
]
}
```
3 . Run lint-staged on staged files using the following command:
```bash
npx lint-staged
```
---
## What is husky?
husky is a tool that manages git hooks, automatically running scripts before each git commit. This setup ensures that lint-staged checks your code before it's committed. It helps you maintain code quality by catching issues before they're finalized.
### Installation
1 . Install `husky` and initialize it:
```bash
# husky init (create .husky folder)
npx husky-init && npm install
# husky - Git hooks install
npx husky install
```
</br>
2 . Check if `prepare` command is added in your `package.json`
```json
"scripts": {
"prepare": "husky install"
},
```
</br>
3 . Edit `.husky > pre-commit` file with the following to run lint-staged before each commit
```bash
#!/usr/bin/env sh
. "$(dirname -- "$0")/_/husky.sh"
npx lint-staged
```
---
### How It Works
1. Stage your code changes.
2. `husky` triggers the pre-commit hook.
3. The pre-commit hook executes `lint-staged`.
4. `lint-staged` runs eslint and prettier checks on staged files.
5. If errors or warnings are found, the commit is prevented with an error message.
