To ensure your apps remains secure, it's crucial to implement robust validation and security measures. This guide will help you to effectively secure file uploads, protecting your systems and end users from malicious intent and malware.
File uploads present several security risks that could compromise both your apps and users. The main risks include:
- **Malicious Files**: Uploaded files can contain viruses, malware, or executable code designed to exploit vulnerabilities.
- **Cross-Site Scripting (XSS)**: Inadequately validated files can contain scripts that execute in the context of the user's browser.
- **Denial-of-Service (DoS) Attacks**: Malicious users upload large files, or numerous smaller files, to exhaust server storage and processing capacities.
- **SQL Injection**: If uploaded file metadata (e.g. filename) are not meticulously sanitised, they can serve as vectors for SQL injection attacks, potentially compromising the database.
Due to the diverse range of risks, relying on a single method is not sufficient - a multi-layered approach is required, combining validation checks, metadata sanitisation, secure configuration and malware scanning.
## Validate the File Extension
File extensions help in identifying the type of file and determining whether it should be accepted. However, just like the `Content-Type` header, file extensions can be manipulated. Despite this, enforcing a whitelist of allowed file extensions can act as a preliminary filter to block obviously dangerous file types. Ensure that only extensions pertinent to your application's needs are accepted.
Checking the file extension is another basic step in securing file uploads. However, like other HTTP headers, file names and extensions can easily be spoofed. Use an allowlist approach, permitting only the specific extensions that your application requires (e.g., `.jpg`, `.png`, `.pdf`). This is a simple validation, and can act as a preliminary filter to block obviously dangerous/incorrect file types.
## Validate the File Size
Limiting the file size is crucial to prevent denial-of-service (DoS) attacks where an attacker attempts to upload extremely large files to exhaust server resources. Set a maximum file size limit according to your application's requirements and enforce this limit server-side to ensure that oversized files are rejected immediately.
## Validate the `Content-Type` Header
Depending on your application's requirements, you will want to accept only particular types of file; for example, for a profile picture you would only want to accept image files.
The `Content-Type` header, sent by the client, indicates the [MIME type](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types) of the file being uploaded. While it's useful to validate as a quick and easy check, it should never be fully trusted - malicious users can easily spoof this header. Therefore, treat the `Content-Type` header as just one of several checks.
How to *definitively* determine the file type is covered in the next section.
## Validate the File Type Based on Signature
As neither the file extension or `Content-Type` header can be trusted, the most effective and reliable way to verify a file's content/media type is by checking its file signature, or "magic number". These are unique [sequences of bytes](https://www.garykessler.net/library/file_sigs.html), usually at the beginning of a file, that indicate its true format. Validation can be performed by reading the first few bytes of the file and matching them against known signatures for allowed file types. For example, a PNG file typically starts with `89 50 4E 47`, and a JPEG file starts with `FF D8 FF`.
This method ensures that the file content matches its purported type, providing a robust defence against file type spoofing. Libraries and tools are available in various programming languages to facilitate this check, or alternatively [Verisys Antivirus API](https://www.ionxsolutions.com/products/antivirus-api?utm_source=devto) can identify [50+ different file formats](https://docs.av.ionxsolutions.com/?utm_source=devto#content-type-detection) for you, while also scanning files for malware.
## Scan for Malware
Incorporating malware scanning into your file upload process is a critical step to ensure the security of both your application and your end users. Malware can be hidden in seemingly harmless files, posing significant risks once they are uploaded and processed.
While there are several malware scanning tools available, not all are equally effective. For instance, [ClamAV](https://www.clamav.net) is a popular open-source antivirus engine, but has notable drawbacks such as poor detection rates, high resource usage, and slow scan times. These limitations can compromise your application's performance and security.
Consider using a more robust and efficient solution like [Verisys Antivirus API](https://www.ionxsolutions.com/products/antivirus-api?utm_source=devto). Verisys Antivirus API offers vastly superior detection capabilities, faster scan times, and a ready-to-use [antivirus API](https://www.ionxsolutions.com/products/antivirus-api?utm_source=devto), making it a reliable choice for integrating malware scanning into your applications.

>
> _By scanning user-generated content and file uploads, Verisys Antivirus API can stop dangerous malware at the edge, before it reaches your servers, applications - or end users._
## Storing Files
Steps required to secure files at rest will depend on the location of stored files - for example, they could be uploaded to object storage such as S3, or they could be stored on disk.
- **Sanitise File Names**: file names can contain malicious characters that your application may be unable to process correctly. Always sanitise file names by removing or replacing special characters, spaces, and potentially executable scripts. Consider renaming files upon upload to a standardised naming convention to prevent any harmful effects.
- **Secure Storage Location**: if storing files on disk (rather than, for example, object storage), uploaded files should be stored in a directory that is not directly accessible via the web. This prevents direct execution or access to the files from a URL.
- **Set Appropriate Permissions**: ensure that uploaded files have the minimum necessary permissions. For instance, files should not be executable if they don't need to be.
## Closing Thoughts
By combining these strategies, developers can significantly enhance the security of file uploads in their applications. A layered approach, which includes malware scanning, provides comprehensive protection against a variety of attack vectors, ensuring that file uploads remain a safe and useful feature.
For a comprehensive guide on securing file uploads and other web application security best practices, refer to [OWASP](https://owasp.org) (Open Worldwide Application Security Project). OWASP provides a wealth of resources, including the [OWASP Top Ten](https://owasp.org/www-project-top-ten/), which highlights the most critical security risks to web applications. In particular, see [Unrestricted File Upload](https://owasp.org/www-community/vulnerabilities/Unrestricted_File_Upload).

I've recently started to work at a trade company and they want me to replace their existing website with a new one. I am not a web developer, I do embedded work with C. I got this job without any web experience because owners of the company are my friends, they trust me personally and they are not in a hurry.
Current website is really simple, only activity on the client side is that users send price request forms for products they want to buy. No user accounts, no online purchases. All negotiation work is done via email by the dealers of the company. At the backend a database with thousands of products.
Each product has couple of images and a few specifications. Existing site is built on asp.net, mssql.
Now they want me to build enhanced version of this site. At first very similar functionality with the current site with improved SEO. But later in the future adding user accounts, online payment system and a mobile app.
Because I'm not a experienced Web developer I decided to build new site with Python and Django. Django provides a lot of useful features out of the box as I see. But my problem is Python, because I've been coding primarily in C, I'm struggling to understand Python way of coding. At first it seems way simpler but I feel fine tuning the code is much more difficult because of loose coding style. For a while I'm curious about the Go. It is closer to the C and I feel I can learn it better than Python. My question is, how hard will it be to build that website with Go without web dev experience. Does Go have enough tools to simplify development process. Does it create a lot of problems when adding new functionalities to the site? | instructured |
1,879,099 | Common Challenges in Cleaning Services and How to Overcome Them | Various is an issue that affects cleaning services for both houses and other commercial buildings as... | 0 | 2024-06-06T11:01:46 | https://dev.to/davidsmith45/common-challenges-in-cleaning-services-and-how-to-overcome-them-1bg5 | cleaningservices |
Various is an issue that affects cleaning services for both houses and other commercial buildings as these challenges increase the chances of hindered efficiency, dissatisfied clients, and worse business. Thus, the awareness of such challenges and their proper solution is the key to providing quality cleaning services and ensuring the growth of the organisation.
## 1. Staffing Issues
Challenge:
There are various obstacles unique to the cleaning industry, and the most famous is the problem of staffing. A serious issue that arises when searching for an external employee is the identification of competent, professional, and motivated performers. RAOs are increased over time and absenteeism adds to the problem.
Solution:
There are methods that should be followed by companies in order to minimize staff problems such as legal staffing, using staffing agencies, competitive wages, and also proper reward systems. Most employers realize that investing in training programs that are continuous enables individuals to learn new knowledge and thereby improve their skills and levels of satisfaction at their workplace. Also, the promotion of a workplace culture that employees are likely to uphold and the level of appreciation of employees, boost the rate of retention. It enables them to grow loyalty and reliability, and, therefore, the development of cultural beliefs that support employees should be encouraged in a firm.
## 2. Quality Control
Challenge:
One of the most acute issues is ensuring the quality and consistency of [cleaning services](https://www.rbcclean.com/services/high-level-cleaning/) for all the cleaning operations made. Customers are never ready to compromise with sanitization, hygiene, and disinfection, and any breach may cost a business its clientele.
Solution:
It is critical to set up measures to prevent variations in quality from the normal standard. This may be comprehensive checklists setting out the cleaning tasks for each work, integrated profile checks and evaluation tools. Cleanliness is an area that can be assessed in terms of performance and anyone willing to enhance performance in this area should consider technology such as cleaning management software. Ongoing training and refresher programs must be conducted to guarantee that all the employees understand the required quality standards being practiced. From the above details, it is clear that proper training of the employees in quality standards followed by constant refresher training can help in ensuring that all employees are conversant with the needed standards.
## 3. Time Management
Challenge:
Twelve tips that can help to control time in a cleaning business A clean is a business where efficient time management is imperative. Whether due to an accident, contaminated water or any other reason that can lead to delays or prolonged cleaning processes, the schedules of the day and the profitability of the operation is affected.
Solution:
It is critical to create a clear timeline and stick to it: This is so true especially when it comes to formulating classes and ensuring that such classes are followed. The use of a timer for work-related tasks allows for evaluating how long it takes to complete each task and further optimization of time expenditures. Informing employees about time management strategies or other practices that can be applied in relations to time increases obedience to time management schedules and timetables when proper time frames are set for accomplishing specific tasks. Also, identifying optimal transportation channels for cleaner – especially in complex or multisite interiors can also save time and money!
## 4. Client Expectations
Challenge:
It can be a somewhat tricky endeavor in some cases, largely because a client and his or her expectations can be incredibly high. This is why communication misunderstanding about the scope of service to be delivered may cause dissatisfaction.
Solution:
First of all, detailing all the provisions of an agreement and possible constraints is crucial in order to build an effective collaboration with the clients. Making sure that one gives specific service agreements that in actuality points out the areas of coverage as well as the expected and prohibited acts reduces cases of confusion. To support it we will arrange regular follow-up meetings as well as feedbacks to make sure that the clients’ expectations are fulfilled and if there are any concerns, they will be solved immediately. Another factor that can also improve client satisfaction is possible to achieve satisfactory results even when making reasonable adjustments as well as be ready for true flexibility. It is heard that cleaning services in Toronto is highly good at customer satisfaction
## 5. Handling Difficult Clients
Challenge:
Managers and supervisors in every trade have problems with customers that are challenging, and the cleaning business is no exception to this. Managing expectations, responding to complaints or speaking to boorish individuals can be difficult.
Solution:
Employers underlining the importance of customer service indicate that training employees in this area is imperative. Arm them with the best ways of handling complaints and any form of conflict, to do so diplomatically and in a composed manner. Performing courtesy and sensitivity, which can minimize boil over actions can at times diffuse situations. Establishing boundaries or protocols when it comes to a partner’s behavior also provides the employee with a policy to shield them from abuse.
## 6. Health and Safety Concerns
Challenge:
This may require employees to keep handling various chemicals and equipment used in cleaning processes, which may lead to several health and safety concerns. It is a well-known fact that one must always adhere to the laws and safety rules and that the occurrence of accidents is inevitable.
Solution:
Especially, clients should be informed about the terms and conditions of work as well as expectations from both parties right from the start. Developing a crystal-clear description of services that need to be rendered, which responsibilities are expected to be handled by the supplier, and which are not, also means anchoring service agreements. One way of making the organization aware that the client's needs are well observed and that all rightful grievances are addressed is through follow-ups and feedback sessions on a regular basis. Politeness and willingness to agree to any probable and rational demands from the clients can also increase the amount of satisfaction.
Cleaning services are the main aspects of business organizations that are met with certain challenges some of which are as follows: As it has been pointed out in this paper, cleaning businesses can solve these challenges and operate more efficiently to deliver higher levels of satisfaction to its customers and ensure its sustained success. Some of the major challenges that organizations face in achieving these goals include: talent management is another major challenge, and the best approach for overcoming this includes implementation of best practices, investment in the training of employees, and use of technology.

When I ask why, the answer is that knowing how the software is deployed makes developers better developers.
In this blog post, I want to take a look at this belief. Does knowledge about deployment make developers better at their job? If yes, how so? And what is the best way to teach developers about deployment?
I also recorded a video on this topic: https://www.youtube.com/watch?v=ZaEFX5DS25g
## Why do most developers know about deployment?
A majority of developers run the software that they work on locally, as part of their development environment. This is why many developers know a lot about the deployment of their software: Because they do it regularly in order to validate their code changes in local deployments.
However **the sad truth is that deployments are often very complicated, and developers spend a lot of time and nerves getting local deployments to work.**
Fortunately, there is an alternative. [Cloud Development Environments](https://cloudomation.com/en/cloud-development-environments/) (CDEs) make it possible for each developer to have private playgrounds where they can validate their code changes before they commit them to a shared repository. CDEs are functionally equivalent to a local deployment, with the difference that they are fully automated and provided to developers remotely. With CDEs, developers can build, test and deploy their code in their own private environment in the CDE with fast feedback loops and with no danger of interfering with other developer’s work – and without having to know anything about deployment.
This is why it makes sense now to ask if developers need to know about the deployment of the software they work on. Previously, there was no other option. Now that there is an alternative, I argue that we need to rethink the scope of what developers have to do and know about.
## What are the upsides of knowing about deployment?
Knowing how to deploy their software can enable developers to make better decisions when writing code, particularly around:
1. Configuration of their software
2. Core architecture of their software
### 1. Configuration of their software
When a developer has to deploy the software they work on themselves, they will intimately know how this software has to be configured. Since developers are also the ones who decide how configuration can be specified for their software, they are much more likely to consider the user experience of configuration when developing configurable features. This is probably the main benefit of forcing developers to deploy their software. Choices about how a software can be configured are something a (backend) developer has to do reasonably frequently.
### 2. Core architecture of their software
The core architecture of a software hugely influences how simple or complex its deployment is. Deployment therefore has to be considered when deciding on the core architecture of a software. However, since architecture decisions are typically made once early in the development of a software, it is the architects or CTOs who take these core architecture decisions who have to know how they plan to deploy their software. For the majority of software developers, this is irrelevant.
### Summary of upsides
So we are left with configuration. It is undoubtedly true that a developer that has had to deploy software that is hard to configure will be more motivated to make their software easily configurable. But relying on this as the mechanism to ensure well-designed configuration for a software is a bad idea. Like any aspect of the software that has a large impact on user experience (in this case the experience of the deployment and operations team of a software), it is something that should be designed by a knowledgeable specialist, who provides guidance on how configuration should be done for a software that other developers then have to follow. This is how feature design works, after all. Otherwise, it will still be each developer deciding on their own what they consider “good and simple configuration”, which will be different for each developer, which most likely again leads to a poor configuration experience overall.
## What are the downsides of knowing about deployment?
There are two main downsides of requiring developers to know how to deploy their software:
1. Time sink: It eats up time and headspace.
2. The myth of the full-stack developer: Few people have the skill and inclination to be good at both coding and deployment.
### 1. Time sink
Knowing about deployment, and having to deploy their software on their own laptops regularly as part of their daily work, are two different things. Unfortunately, the latter is the sad reality for many developers, and it is justified with the “need to know about deployment”. I have already described that knowledge about the deployment of a software has only marginal benefits for developers. In addition to this, the second misconception is that local deployments as part of a developers work are a good way to teach developers the things that they should know about deployment. It is not.
If you want your developers to know about the pains of deployment, it may be a good idea to ask them to manually deploy the software they work on as part of their onboarding, or as a regular exercise every once in a while. If you really think that knowing about deployment is valuable for your developers, then this is a good way to teach them: If the deployment is painful, they will remember it very well.
If developers do local deployments daily, they will get used to many of the pains of it and lose awareness. That removes even the marginal benefit of developer’s knowledge about deployment: They might not even try to make it better anymore.
But the worst part is that it eats up developers time and headspace on a daily basis. It is a cost factor that many companies are not much aware of, because time spent troubleshooting local deployments is typically not tracked separately. Instead, it is padded on top of each task that a developer works on. But **the time spent on local deployment can reach as much as 25% of a developer’s time (in extreme cases), and typically is somewhere between 5-10% of time of a developer** when it works fairly well.
That is a LOT of time!
### 2. The myth of the full-stack developer
The scope of what a developer is supposed to know is seemingly endless. Even though many specific job titles exist that describe people whose primary focus is deployment and operation of software (operations, devops, site reliability engineer (SRE), …), developers are often assumed to be able to fulfill those functions in addition to their primary function. Often, testing, user experience, architecture, backend and frontend development are also mingled in, leading to the all-encompassing job description of full-stack developer.
There are people who know a lot about many aspects of software development, who can reasonably claim to be full-stack developers and do a decent job in any of the mentioned areas. But for most developers, working as full-stack developers will result in products like this:
The truth is that most people, including developers, hugely benefit from specialisation. Having one area to focus on where one can build up knowledge allows one to reach higher levels of productivity and expertise much faster than when developers are asked to learn about everything at once.
This is especially true for complex software. State-of-the-art business software nowadays often has a lot of components and highly complex deployment logic. As long as deployment can be expressed with a simple “npm run build”, any developer will be able to handle that. But that is hardly ever the case anymore. Many developers spend 10% or more of their time just managing local deployments. The majority of this time, they spend on troubleshooting. But in order to troubleshoot local deployments, developers do not only have to spend time – they also have to know a lot about tools like Docker or minikube or other tools specific to the deployment of their software.
Bottom line: **Expecting a very broad skillset from developers will exclude the majority of developers from fulfilling such a role successfully.** Even those few full-stack developers that do exist, each one will have specialties and areas where they are less skilled. Finding people who are good in one area is much simpler and will lead to much better outcomes for everyone.
## Conclusion
Deployment is an important aspect of a software. It is probably a good idea for most developers to know at least a little bit about the deployment of their software, much in the same way as it is a good idea for each developer to know how to use the software they work on so that they can make better decisions about user experience.
However, much in the same way, developers are not generally required to (or trusted with) making decisions about user experience on their own, even if they have intimate knowledge of the software. It is simply not their speciality. There are user experience designers for a reason, because it is a complex area of expertise that requires knowledge and inclination that doesn’t necessarily overlap with that of a developer whose job it is to write code.
It is exactly the same with deployment. Deployment experts exist for a reason – because it is a complex area of expertise that not every developer should be expected to master, on top of their development expertise. Developers should be required to follow best practices or company-internal guidelines when making decisions that influence deployment. But they should not have to spend hours and hours each day struggling with local deployment.
My conclusion: CTOs and directors of engineering expect their developers to handle deployment because:
* It has always been this way and they may not yet realise that it is not necessary anymore.
* Knowing about deployment serves as a proxy for the general skill and knowledge of a developer. (I could also put it more bluntly: It propagates the unhelpful stereotype of the all-knowing full-stack developer as the ideal developer.)
Neither reason stands up to scrutiny.
## Bottom line: It’s expensive and has few benefits
To summarise: Few developers have the inclination, experience and skillset to fulfil the stereotype of the full-stack developer that knows how to code and deploy their software. Knowing about the deployment of a software has only marginal benefits at best, but requires a lot of time and energy to learn and manage.
Consequently, forcing developers to learn about Docker, minikube, network configurations and a whole lot of other things and tools that they need only for local deployment is a huge waste. Developers generally don’t even like doing this. It is a drag on both productivity and happiness.
**This is good news!** It means that there is a huge amount of time and headspace that developers could stop investing in local deployment. There is a big opportunity to make developers a lot happier and more productive.
And fortunately, it is easily possible to spare developers the pains of local deployments. CDEs are tools specifically designed to do this. They allow developers to focus on writing great code, without having to worry about deployment.

1,879,097 | Service Discovery and Service Registry | Service Discovery ve Service Registry, mikroservis mimarisinin önemli bileşenleridir. Her ikisi... | 0 | 2024-06-06T10:59:08 | https://dev.to/mustafacam/service-registry-n97 |
**Service Discovery** ve **Service Registry**, mikroservis mimarisinin önemli bileşenleridir. Her ikisi de mikroservislerin dinamik olarak keşfedilmesini ve birbirleriyle iletişim kurmasını sağlar. Ancak, bunlar farklı roller oynar ve birlikte çalışarak mikroservislerin yönetimini kolaylaştırır.
### Service Registry (Servis Kayıt Defteri)
**Service Registry**, mikroservislerin ağ üzerindeki yerlerini (IP adresi ve port) kaydettikleri merkezi bir kayıt defteridir. Mikroservisler başlatıldığında kendilerini bu kayıt defterine kaydederler ve kapandıklarında veya kullanılamaz hale geldiklerinde bu kayıttan silinirler.
#### Özellikleri:
1. **Dinamik Kayıt ve Kaldırma**: Servisler başlatıldığında kendilerini kaydeder ve kapandıklarında kayıttan kaldırırlar.
2. **Sağlık Kontrolleri**: Service Registry, servislerin sağlık durumlarını izleyebilir ve yalnızca sağlıklı servislerin kullanılmasını sağlar.
3. **Merkezi Yönetim**: Servislerin nerede çalıştığını merkezi bir şekilde yönetir.
#### Örnek: Netflix Eureka
Eureka, popüler bir Service Registry örneğidir. Mikroservisler Eureka'ya kendilerini kaydeder ve diğer servisler de ihtiyaç duyduklarında Eureka'dan bu servislerin yerini öğrenirler.
### Service Discovery (Servis Keşfi)
**Service Discovery**, mikroservislerin birbirlerini dinamik olarak bulmasını sağlayan bir mekanizmadır. Service Discovery, iki ana yöntemle gerçekleştirilir: Client-Side Discovery ve Server-Side Discovery.
#### Client-Side Discovery
Bu yöntemde, istemci uygulaması doğrudan Service Registry'yi sorgular ve ihtiyaç duyduğu servisin yerini öğrenir. İstemci, aldığı bilgilerle servise doğrudan bağlantı kurar.
#### Server-Side Discovery
Bu yöntemde, istemci bir istek yapar ve bu istek bir yük dengeleyici veya API Gateway aracılığıyla yönlendirilir. Yük dengeleyici, Service Registry'yi sorgular ve servisin yerini bulur, ardından isteği doğru servise iletir.
### Örnek Kullanım Senaryosu
Bir mikroservis mimarisinde, farklı servislerin birbirleriyle nasıl iletişim kurduğunu inceleyelim:
1. **Eureka Server Kurulumu**
Eureka Server, merkezi bir kayıt defteri olarak çalışır. Mikroservisler bu server'a kendilerini kaydederler.
#### Bağımlılık Ekleyin:
```xml
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
```
#### Ana Sınıf:
```java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
```
#### Konfigürasyon:
```yaml
server:
port: 8761
eureka:
client:
register-with-eureka: false
fetch-registry: false
server:
wait-time-in-ms-when-sync-empty: 0
```
2. **Eureka Client Kurulumu (Mikroservis)**
Her mikroservis, Eureka Server'a kendini kaydeder ve diğer servislerin yerlerini öğrenir.
#### Bağımlılık Ekleyin:
```xml
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
```
#### Ana Sınıf:
```java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
@SpringBootApplication
@EnableEurekaClient
public class SomeServiceApplication {
public static void main(String[] args) {
SpringApplication.run(SomeServiceApplication.class, args);
}
}
```
#### Konfigürasyon:
```yaml
eureka:
client:
service-url:
defaultZone: http://localhost:8761/eureka/
```
3. **Feign Client Kullanımı**
Mikroservisler arasında iletişim kurmak için Feign Client kullanılabilir.
#### Feign Client Arayüzü:
```java
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
@FeignClient(name = "other-service")
public interface OtherServiceClient {
@GetMapping("/resource/{id}")
Resource getResourceById(@PathVariable("id") Long id);
}
```
#### Servis Kullanımı:
```java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class SomeService {
private final OtherServiceClient otherServiceClient;
@Autowired
public SomeService(OtherServiceClient otherServiceClient) {
this.otherServiceClient = otherServiceClient;
}
public Resource fetchResource(Long id) {
return otherServiceClient.getResourceById(id);
}
}
```
### Sonuç
**Service Registry** ve **Service Discovery**, mikroservislerin dinamik ve ölçeklenebilir bir şekilde yönetilmesini sağlayan kritik bileşenlerdir. Service Registry, mikroservislerin yerlerini kaydederken, Service Discovery bu kayıtları kullanarak mikroservislerin birbirlerini bulmasını ve iletişim kurmasını sağlar. Bu mekanizmalar, mikroservis mimarisinin esnekliğini ve yönetilebilirliğini artırır. | mustafacam | |

Object detection is a crucial task in computer vision that involves identifying and locating objects within an image or a video stream. The implementation of object detection has become more accessible than ever before with advancements in [deep learning libraries](https://www.codetrade.io/blog/deep-learning-libraries-you-need-to-know-in-2024/) like TensorFlow.
In this blog post, we will walk through the process of performing object detection using a pre-trained model in TensorFlow, complete with code examples. Let’s start.
Explore More: [How To Train TensorFlow Object Detection In Google Colab: A Step-by-Step Guide](https://www.codetrade.io/blog/train-tensorflow-object-detection-in-google-colab/)
## **Steps to Build Object Detection Using Pre-Trained Models in TensorFlow**
Before diving into the code, you must set up your environment and prepare your dataset. In this example, we’ll use a pre-trained model called ssd_mobilenet_v2_fpnlite_320x320_coco17_tpu-8 from TensorFlow’s model zoo, which is trained on the COCO dataset.
### **1. Data Preparation**
First, let’s organize our data into the required directory structure:
```
import os
import shutil
import glob
import xml.etree.ElementTree as ET
import pandas as pd
# Create necessary directories
os.mkdir('data')
# Unzip your dataset into the 'data' directory
# My dataset is 'Fruit_dataset.zip'
# Replace the path with your dataset's actual path
!unzip /content/drive/MyDrive/Fruit_dataset.zip -d /content/data
# Move image and annotation files to their respective folders
# Adjust paths according to your dataset structure
# This code assumes that your dataset contains both 'jpg' and 'xml' files
# and organizes them into 'annotations_train', 'images_train', 'annotations_test', and 'images_test' folders.
# You may need to adapt this structure to your dataset.
# images & annotations for test data
for dir_name, _, filenames in os.walk('/content/data/test_zip/test'):
for filename in filenames:
if filename.endswith('xml'):
destination_path = '/content/data/test_zip/test/annotations_test'
elif filename.endswith('jpg'):
destination_path = '/content/data/test_zip/test/images_test'
source_path = os.path.join(dir_name, filename)
try:
shutil.move(source_path, destination_path)
except:
pass
# images & annotations for training data
for dir_name, _, filenames in os.walk('/content/data/train_zip/train'):
for filename in filenames:
if filename.endswith('xml'):
destination_path = '/content/data/train_zip/train/annotations_train'
elif filename.endswith('jpg'):
destination_path = '/content/data/train_zip/train/images_train'
source_path = os.path.join(dir_name, filename)
try:
shutil.move(source_path, destination_path)
except:
pass
```
### **2. Convert XML Annotations to CSV**
To train a model, we need to convert the XML annotation files into a CSV format that TensorFlow can use. We’ll create a function for this purpose:
```
import glob
import xml.etree.ElementTree as ET
import pandas as pd
def xml_to_csv(path):
classes_names = []
xml_list = []
for xml_file in glob.glob(path + '/*.xml'):
tree = ET.parse(xml_file)
root = tree.getroot()
for member in root.findall('object'):
classes_names.append(member[0].text)
value = (root.find('filename').text,
int(root.find('size')[0].text),
int(root.find('size')[1].text),
member[0].text,
int(member[4][0].text),
int(member[4][1].text),
int(member[4][2].text),
int(member[4][3].text))
xml_list.append(value)
column_name = ['filename', 'width', 'height', 'class', 'xmin', 'ymin', 'xmax', 'ymax']
xml_df = pd.DataFrame(xml_list, columns=column_name)
classes_names = list(set(classes_names))
classes_names.sort()
return xml_df, classes_names
# Convert XML annotations to CSV for both training and testing data
for label_path in ['/content/data/train_zip/train/annotations_train', '/content/data/test_zip/test/annotations_test']:
xml_df, classes = xml_to_csv(label_path)
xml_df.to_csv(f'{label_path}.csv', index=None)
print(Successfully converted {label_path} xml to csv.')
```
This code outputs CSV files summarizing image annotations. Each file details the bounding boxes and corresponding class labels for all objects within an image.
### **3. Create TFRecord Files**
The next step is to convert our data into TFRecords. This format is essential for training TensorFlow object detection models efficiently. We’ll utilize the `generate_tfrecord.py` script included in the TensorFlow Object Detection API.
```
#Usage:
#!python generate_tfrecord.py output.csv output.pbtxt /path/to/images output.tfrecords
# For train.record
!python generate_tfrecord.py /content/data/train_zip/train/annotations_train.csv /content/label_map.pbtxt /content/data/train_zip/train/images_train/ train.record
# For test.record
!python generate_tfrecord.py /content/data/test_zip/test/annotations_test.csv /content/label_map.pbtxt /content/data/test_zip/test/images_test/ test.record
```
Ensure that you have a label_map.pbtxt file containing class labels and IDs in your working directory or adjust the path accordingly.

Organizations can save enormously while keeping up with performance and scalability by taking proactive approaches to cost optimization. Mastering these fundamental strategies is crucial for achieving efficiency gains and maximizing returns in the fiercely competed market of AWS development services.
## Identifying and Eliminating Unnecessary Expenses
To maintain cost-efficiency and optimize resource allocation, it is very important to identify and eliminate unnecessary expenditures in AWS Development Services. Complexity of AWS pricing models as well as potential hidden costs are among the primary challenges that businesses face. In conducting regular audits of AWS usage and expenditure, organizations would be able to spot areas where resources have been underutilized or overspent. The first step is to examine user patterns, service usage reports, and other AWS applications like Cost Explorer for visibility into spending.
Besides, putting into practice strict budgeting measures and cost control policies can help prevent redundant expenses from happening in the first place. These encompass setting up limits on expenditure, using cost tracking capabilities of Budgets within AWS and developing clear governance rules associated with resource provisioning. Finally, continuing optimization initiatives such as rightsizing instances or optimizing storage greatly contribute to eliminating waste in terms of financial outlays. As a result businesses can allocate their AWS assets more efficiently thus generating substantial savings on costs alongside improved overall financial health.

These tools automatically restart your server whenever changes are detected in your codebase. Here's how to set them up:
### Using Nodemon:
1. First, install `nodemon` globally or locally in your project:
```bash
codenpm install -g nodemon
# or
npm install --save-dev nodemon
```
1. Then, you can start your Express.js application using `nodemon`:
```bash
nodemon your-app.js
```
Replace `your-app.js` with the entry point of your Express.js application.
### Using Webpack with webpack-dev-server:
1. Install `webpack-dev-server` and `webpack` as dev dependencies:
```bash
npm install --save-dev webpack webpack-dev-server
```
1. Configure webpack to bundle your Express.js application. You can create a `webpack.config.js` file for this purpose.
2. Set up `webpack-dev-server` to serve your bundled files:
```json
"scripts": {
"start": "webpack serve --open"
}
```
1. Now, running `npm start` will start the webpack-dev-server and automatically reload the server when changes are made.
### Using Express.js Middleware:
Alternatively, you can use `express.js` middleware like `express.js-hmr` to achieve hot reloading. Here's how you can set it up:
1. Install `express.js-hmr`:
```bash
npm install --save-dev express.js-hmr
```
1. Use it in your Express.js application:
```js
const express = require('express');
const app = express();
if (process.env.NODE_ENV === 'development') {
const hmr = require('express.js-hmr');
app.use(hmr());
}
// Your routes and middleware here...
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
```
This middleware enables hot module replacement (HMR) for your Express.js application during development.
Choose the method that best suits your workflow and preferences. Each approach has its own advantages, so consider factors like ease of setup, integration with your existing workflow, and compatibility with your project structure. | kamilrashidev |

1,879,085 | How I Integrated IoT to Control Our HVAC System with Python | At our company, we had an old HVAC system that was inefficient and hard to control. We decided to... | 0 | 2024-06-06T10:45:06 | https://dev.to/daniellos/how-i-integrated-iot-to-control-our-hvac-system-with-python-2jcj | python, iot | At our company, we had an old HVAC system that was inefficient and hard to control. We decided to modernize it by using IoT technology. The goal was simple: make the system more efficient and allow us to monitor it remotely. Here’s a story about how we achieved that using Python, some handy libraries, and a Raspberry Pi.
**Spoiler:** It wasn’t all smooth sailing.
## Tools and Technologies
## To start, I gathered the necessary tools and technologies. Here’s what we used:
- Raspberry Pi: This small, affordable computer was the brain of our operation.
- Python: A programming language that's both powerful and easy to learn.
- paho-mqtt: A library for MQTT communication, which is like a postal service for messages between devices.
- hvac: A library to control the HVAC system.
- Sensors and Actuators: These helped us monitor and control different aspects of the HVAC system.
We chose these tools because they are reliable and have a lot of support from the tech community. It's like building a Lego set; we just had to follow the instructions and put the pieces together.
## Setting Up the Environment
First, we needed to set up our Raspberry Pi. Here’s a simple way to do it:
Install Python:
`sudo apt-get update
sudo apt-get install python3`
This command updates the system and installs Python, which is like giving your Raspberry Pi a brain.
**Install Required Libraries:**
pip install paho-mqtt hvac
This installs the libraries we need to talk to our HVAC system and control it.
With these steps, our Raspberry Pi was ready to become the smart controller for our HVAC system. It felt like teaching an old dog new tricks!
### Connecting the Raspberry Pi to the HVAC System
Now that our Raspberry Pi was ready, we moved on to connecting it to the HVAC system. Here’s how we did it:
1. **Physical Setup**: We connected sensors and actuators to the Raspberry Pi. These sensors measured things like temperature and humidity, while actuators controlled parts of the HVAC system like the fans and vents. Think of it like wiring up a home stereo system, but with more wires and a bit more patience.
2. **Configuration**: We had to make sure the sensors and actuators were properly configured to work with our HVAC system. This meant checking connections and ensuring the devices could communicate with each other. It was a bit like making sure all the band members are in sync before a concert.
This setup allowed us to monitor and control the HVAC system using our Raspberry Pi.
### Writing the Control Code
With the hardware connected, it was time to write the code to control the HVAC system. Here’s a simple breakdown:
1. **Initialize MQTT Client**:
```python
import paho.mqtt.client as mqtt
client = mqtt.Client()
client.connect("mqtt_broker_address", 1883, 60)
```
This code sets up the MQTT client, which is like setting up a phone line for our Raspberry Pi to send and receive messages.
2. **Subscribe to Control Topics**:
```python
def on_message(client, userdata, msg):
if msg.topic == "hvac/control":
# Process control message
client.subscribe("hvac/control")
client.on_message = on_message
```
Here, we subscribed to a control topic. It’s like telling the Raspberry Pi to listen for commands from us.
3. **Send Commands**:
```python
def control_hvac(command):
client.publish("hvac/command", command)
control_hvac("turn_on")
```
This part sends commands to the HVAC system. It’s like giving our Raspberry Pi the ability to control the system by flipping a virtual switch.
### Monitoring and Logging
Once we had control over the HVAC system, the next step was to monitor its performance and log the data. This helps us keep an eye on the system and make sure everything runs smoothly.
1. **Setting Up Sensors**: We set up sensors to measure temperature, humidity, and other relevant metrics. These sensors send data to the Raspberry Pi.
2. **Logging Data**:
We wrote a Python script to log data from the sensors:
```python
import time
def read_sensor():
# Code to read data from the sensor
return sensor_data
def log_data(data):
with open("hvac_log.csv", "a") as file:
file.write(f"{time.time()},{data}\n")
while True:
sensor_data = read_sensor()
log_data(sensor_data)
time.sleep(60)
```
This script reads data from the sensors every minute and writes it to a log file. It’s like keeping a diary of how the HVAC system is performing.
3. **Visualizing Data**: We used simple tools to visualize the logged data. This helped us see trends and spot any issues early.
### Challenges Faced
No project is without its hurdles, and we faced our fair share. Here are some of the challenges we encountered:
1. **Sensor Accuracy**: Some sensors were not providing accurate readings. This made it hard to trust the data we were getting.
2. **MQTT Connectivity**: We experienced intermittent connectivity issues with our MQTT setup. Sometimes, messages weren’t being sent or received as expected.
3. **Integration Issues**: Integrating the new system with our existing HVAC setup was more complex than anticipated. We had to deal with compatibility issues and unexpected bugs.
These challenges were tough, but they also provided valuable learning experiences. We could use some advice from the community on how to address these issues effectively.
During the process I got some (free) help from [Lightning Mechanical](https://lightningmechanicalservice.com) so I want to thanks them :)
### Conclusion
Despite the challenges, we successfully integrated IoT technology with our HVAC system. We can now monitor and control the system remotely, which has already shown improvements in efficiency. However, there’s still work to be done. We plan to continue refining the system and solving the issues we encountered.
We’ll keep you updated on our progress and share more insights as we go. We’d love to hear your feedback and any suggestions you might have.
If you’ve worked on similar projects or have expertise in IoT and HVAC systems, we’d love to hear from you. Let’s collaborate to enhance our setup and achieve even greater efficiency and control.

1,879,084 | How to Force Git Pull to Overwrite Local Files | Since the work of programmers has become teamwork – that is, practically always – there has been a... | 0 | 2024-06-06T10:43:05 | https://gitprotect.io/blog/how-to-force-git-pull-to-overwrite-local-files/ | devops, coding, programming, developer | Since the work of programmers has become teamwork – that is, practically always – there has been a need to synchronize the code created by different people. Currently, the world is so computerized that even companies that do not deal with software, more and more often have internal IT departments for their own needs. As a result, we have more and more developers, and that means more and more code to sync, and it repeats over and over again.
While working on Linux, Linus Torvalds felt this problem the hard way and developed the Git system, which makes it much easier to synchronize code and, as a result, speeds up its production. Git is known as a distributed version control system. But what does that mean? Well, **each working copy on the developer’s computer is literally a copy of the entire repository**. Thanks to this, we can make any changes locally, add or remove code, create new branches, etc. It is also a security feature because in the event of a failure we can restore the repository based on only one local version. Although I wouldn’t rely on that and we should always have the right backup tool.
There is one more thing related to such distributed architecture – determining which copy will be the main one. All the others will integrate into it. Our changes will be uploaded there and we will download other changes from it. Thanks to this solution, each local copy knows only about one external repository and does not have to integrate with any other. This solution is borrowed from centralized solutions, such as SVN, but it is worth being aware that this is just a standard and practice, not a feature or limitation of the Git tool itself.
## Git workflows
Since we are talking about standards and practices, it is worth getting acquainted with the different types of [Git workflows](https://gitprotect.io/blog/git-workflows/). It is important that regardless of the workflow used, synchronization of changes comes down to two operations – downloading new changes from the server (pull) and sending our changes there (push). If every programmer creates new files, there is no problem here, he or she downloads code created by others and adds what he or she created themself. However, real-life is far from perfection and this is rarely the case. Usually, the team works on the same files, which runs the risk of overwriting changes made by someone else. The use of the appropriate workflow, mentioned in the link above, allows us to deal with it.
## Git push and git pull calls
Leaving the workflow behind us, let’s analyze how exactly the data synchronization mechanism in Git works. Let’s start with what happens when we send our changes out. The operation for this is called ‘push’. Here is a small digression on merge strategies. If the story is linear and the merge adds another commit at the end, then the so-called fast-forward occurs. It just adds the commits that were sent and updates the branch so that it now points to the newly added changes. The second situation is when we have a branched history and there is an additional so-called merge commit. Let’s see it in the pictures below:
fast-forward
3-way merge
Let’s go back to the “push” operation. **It is only possible if fast-forward execution is possible.** Our local changes land in the remote repository and all other project members can download them from now on. If a fast-forward merge is not possible, Git will not let us sync as it is and we will get an error message. Most often it results in the fact that we have to locally download the latest version of the code, perform the merge on our machine and only then try to send our changes to the remote repository.
I mentioned downloading the latest version of the code. This is what the “pull” operation is for. In fact, it takes two steps, first is the fetch operation, which downloads code from a remote repository to the so-called **remote-branch, which is a local copy of what’s outside**. And then a merge to the local working branch is performed. Then our changes will be merged (or not, more on that in a moment) and we have the current code version, identical to the state in the remote repository.
## Merge conflict
Git can efficiently merge changes automatically, but this is not always possible. Because what should happen when two people simultaneously change the name of the same file, and into two completely different ones? Are you sure the machine should decide? Of course not, and Git is aware of that. In the case of changes that cannot be unequivocally assessed and automatically combined, there is the so-called “merge conflict”. This is a situation where the merge operation was interrupted mid-execution and manual action is required to end the conflict. At this point, I will skip the topic of available graphical tools to facilitate this task and the details of conflict resolution itself.
It is important that the conflict can be solved in two ways – interrupt the operation and return to the state before the merge option was run, or select the changes to be accepted and approve them with the commit operation. A new so-called **merge commit, which introduces conflict-free changes to the repository**. Now just send a new commit to the external repository and the situation is under control.
An effective method of avoiding conflicts (or rather minimizing their number) is frequent synchronization. This helps to reduce the number of conflicts, and even if they do occur, they are usually easier to resolve. But let’s consider one thing – **can git pull overwrite local changes**? Well.. not by default. Remember that in the case of a “pull” operation, there are actually two operations – fetch and merge. Eventually, even if our changes are replaced locally, it will be done through a merge commit, so what we had in the code before will still exist in previous commits. We cannot talk about overwriting here, since our code has not disappeared from the repository. However, as a reminder, this is the case of the default (and most common) behavior. So let’s have fun and try to really overwrite something.
## Overwriting and “force” parameter
There is the magic word **‘force’ in Git, which is the parameter of many commands**. It is both salutary and dangerous, depending on whether it is used correctly and consciously. In general, this parameter allows us to force an operation that Git would not normally want to perform. There can be many reasons here, e.g. history mismatch at the time of push execution. Earlier I described how “push” and “pull” operations work by default, but now let’s check what happens when we add this new parameter to them. So how to force git pull? To make it short, you can force git repo to pull data from some remote repository by fetching data from it and then resetting changes to the branch.
**Git pull force actually affects only one of its components**, namely the fetch operation. In one case, to be exact. Let’s take a look at the Git documentation for the “fetch force” operation for a moment:
When **git fetch** is used with <src>:<dst> refspec it may refuse to update the local branch as discussed in the <refspec> part below. This option overrides that check.
And further, in the <refspec> section, we can find an example that explains the <src> and <dst> parameters above:
tag <tag> means the same as refs/tags/<tag>:refs/tags/<tag>; it requests fetching everything up to the given tag.
The remote ref that matches <src> is fetched, and if <dst> is not an empty string, an attempt is made to update the local ref that matches it.
So here we have our potential use of the –force flag. As described in the documentation, until we specify the second parameter manually, the parameters of <src> and <dst> are the same and there should be no error here. This is the default behavior. However, if we intentionally want to download the content of another branch under a given branch, so our parameter values will be different, there may be a synchronization problem here and Git will refuse to perform such an operation. Here, our new friend comes to the rescue, which will force such a step to be performed despite the differences in both branches. However, we must be sure what we are doing, because this step will override our local changes. So the answer to ‘how to force pull in git?’ is simple – **use the “force” parameter at the end of our statement**.
## What does git push force do?
Let’s move on to the next operation. What does git push force do? Here the matter is a bit different because **git push force will overwrite changes in the remote repository, not our local one**. Which is potentially much more dangerous! By default, Git will only push if it succeeds in doing the aforementioned fast-forward merge. In any other case, we will get an error and the operation will be rolled back. This is well structured because it forces us to keep order in the history and to sync locally before we can send our code out.
Well, we are not talking today about ‘normal’ actions, but about how to avoid them with our magic flag. Adding “force” during a “push” operation will cause Git to accept our every change, no matter how messy we’ve made in the commits history. We just say “do it anyway” and overwrite the story forever. It is very dangerous because it creates the risk of losing a large amount of data and usually such an operation is unacceptable in a well-configured repository. Let me also post another quote from the Git documentation on this topic:
This flag (…) can cause the remote repository to lose commits; use it with care.
Boom. If we do something like this, at this point our repository history has already been overwritten and we have potentially lost some data.
## Is git force push bad?
I will answer in my favorite way – it depends. Generally, as agreed, it is a very dangerous tool and must be used wisely. But can it be called bad? It will cause a lot of problems for us when misused, but for some reason, it still exists in Git. I will give you a simple example from my own experience. I teach people programming and we often use Git repositories for workshops. Each workshop has its own repo, these are not big projects but are made in large numbers. Often, when a new one is created, there is already some commit in it, e.g. with a README file or something like that. Well, I already have a locally created project that I want to put all into this repository and not mess with any merging of changes. The “force” parameter comes to your aid. The effect is that I delete everything that was in this repository so far and put there only what I prepared earlier myself. A simple example, but it shows the usefulness and principle of operation of this tool.
There is also a fundamental difference between using git push force and git pull force. Overwriting changes while downloading modifies our local copy, so it is not a dangerous action from the perspective of the entire project. Up to a point at least. In the case of “push” operation, the problem is more serious because it affects everyone using this repository and can be quite a mess. Fixing such a problem can take a lot of time and nerves. And money too. It should come as no surprise to anyone when I mention the necessity to make backups.
## Summary
So let’s put it all together. Is using the “force” option risky? Yes. Very much, especially in the case of “push” operation. Do I need special permissions to use this option? By default, Git does not impose this, but popular services such as GitHub and Bitbucket do allow this. And important branches should have such security if we take our projects seriously. This is called protected branches, and it allows you to make various rules, including protection against the “force” option. And is it a bad practice to use this option? No, as long as we use it for the purpose for which it was created and we are fully aware of the consequences.
Finally – do we need a backup? Of course. It is always needed and we should always remember about it. Especially when we play the very dangerous game of overwriting history by force.

1,875,100 | Bahas Tipis Seputar Redis | Intro Yo! Ini tulisan pertama saya di komunitas ini. Saya akan coba untuk membahas seputar... | 0 | 2024-06-06T10:37:52 | https://dev.to/revtm/bahas-tipis-seputar-redis-65d | backend, webdev, redis, tutorial | ### Intro
Yo! Ini tulisan pertama saya di komunitas ini. Saya akan coba untuk membahas seputar Redis dengan format Question and Answer (QnA) ya. Selamat membaca!😁
### Seputar Redis
#### Redis itu apa sih?
Mudahnya, kita dapat menyebut Redis ini sebagai database. Namun, Redis tidak menyimpan datanya di storage seperti database pada umumnya, melainkan ia menyimpan semua datanya di dalam memory.
Oh iya, Redis termasuk keluarga NoSQL ya, karena Redis tidak menyimpan data-datanya dalam bentuk tabel relasi yang rumit seperti MySQL dan kawan-kawan, tetapi hanya dalam bentuk pasangan key-value.
Lebih jelasnya, Key selalu bersifat unik dan berfungsi seperti ID dari satu baris data di tabel database SQL. Sedangkan Value adalah isi data yang terkait dengan Key tadi. Jadi kalau kita mau manggil data yang kita butuhkan, cukup panggil key-nya aja deh. Sederhana bukan?
#### Mengapa di memory?🤔
Karena akses ke memory lebih cepat dari pada ke storage. Salah satu contoh use case dari Redis adalah digunakan sebagai cache dari aplikasi. Berikut ilustrasi penggunaannya:
Dari ilustrasi di atas, setelah request masuk maka server akan melakukan pencarian terlebih dahulu ke Redis berdasarkan key. Jika key tersebut ditemukan, maka server akan menarik data dari Redis dan kemudian mengirim langsung data tersebut ke user sebagai response. Namun bila key tidak ditemukan, maka server akan melakukan proses pencarian data mentah ke database di storage, lalu memproses data yang diambil, dan kemudian mengirim data hasil sebagai response ke user sekaligus secara parallel menyimpan data hasil ke Redis.
Dengan demikian adanya Redis sebagai cache akan menghemat waktu untuk memproses request karena tidak perlu akses data ke storage dan juga melakukan proses data lagi⚡.
#### Btw kalo servernya mati datanya ilang dong ya? Kan ditaruh di memory🤔
Tenang, hal ini sudah dipikirkan oleh pembuat Redis nya kok. Berdasarkan artikel yang mereka tulis, terdapat opsi mekanisme untuk menyimpan data ke storage baik dalam bentuk snapshot atau data log secara berkala. Kalian bisa membaca lebih lanjut di [sini](https://redis.io/learn/operate/redis-at-scale/persistence-and-durability/persistence-options-in-redis).
#### Jika suatu waktu membutuhkan peningkatan performa, apakah kita dapat melakukan scaling di Redis?
Sebelum masuk ke jawaban, mungkin kita perlu ketahui dahulu perbedaan empat jenis teknik scaling di bawah ini ya:
- scale-up vs scale-down
- scale-out vs scale-in
Singkatnya, pada teknik **scale-up** kita melakukan scaling secara vertikal yaitu dengan menambah kapasitas resource seperti jumlah CPU dan memory pada satu server. Sebaliknya, pada teknik **scale-down** kita melakukan hal kebalikan dari metode scale-up yaitu kita mengurangi jumlah resource CPU atau memory pada server.
Sedangkan, pada teknik **scale-out** kita melakukan proses scaling secara horizontal yaitu dengan menambah jumlah server dengan spesifikasi yang sama sehingga terbentuk satu group of servers (cluster) yang bekerja secara paralel. Sebaliknya, pada teknik **scale-in** kita melakukannya dengan menghapus atau memutus koneksi satu atau lebih server dari cluster tadi.
Oke, jadi sudah lumayan paham ya perbedaannya. Sekarang kita balik lagi ke Redis :D
Berdasarkan artikel yang saya rujuk di [sini](https://redisson.org/glossary/sharding.html), Redis menggunakan teknik scaling secara horizontal/scale-out yang biasa dikenal dengan istilah Sharding.
Penjelasan mudahnya, pada teknik sharding kita membagi kumpulan key-value dari satu server Redis atau biasa disebut node kemudian mendistribusikan masing-masing key-value tersebut ke beberapa node berbeda dalam satu cluster.
#### Bagaimana mengetahui posisi key berada di dalam node keberapa di cluster?
Redis memiliki algoritma khusus dalam menentukan posisi key berada. Algoritma tersebut menggunakan pendekatan [Hash Slot](https://redis.io/learn/operate/redis-at-scale/scalability/clustering-in-redis) di mana jumlah slotnya selalu konstan yaitu berjumlah 16384. Selain itu perlu diketahui juga dalam satu node Redis bisa memiliki banyak hash slot dan satu hash slot memiliki banyak key.
Untuk mengetahui posisi key berada di hash slot mana kita cukup menghitung nilai CRC16 dari key dan di-modulo-kan dengan jumlah hash slot (16384).
> hash slot = CRC16(key) mod 16384
Misalkan kita menggunakan Redis cluster seperti ilustrasi di atas dan kemudian kita memiliki key = "foo". Maka untuk mengetahui posisi key berada di hash slot mana kita dapat menghitungnya sebagai berikut:
> crc16Hash = CRC16("foo") = 44950
> hashSlot = crc16Hash mod 16384 = 44950 mod 16384 = 12182
Maka sesuai rentang pada masing-masing node, key "foo" berada pada primary node ke-3🎉.
### Penutup
Oke, mungkin cukup segini dulu ya pembahasannya, jika ada kesalahan pada penjelasan saya di atas mohon bantuan koreksinya ya gaes🤭
Thankyou~ | revtm |
1,879,079 | Maîtriser le DevOps : Fusionner les équipes pour optimiser la performance et la valeur ajoutée | Le DevOps fusionne le développement (Dev) et les opérations (Ops) pour harmoniser les équipes, les... | 0 | 2024-06-06T10:36:34 | https://dev.to/medgardherv/maitriser-le-devops-fusionner-les-equipes-pour-optimiser-la-performance-et-la-valeur-ajoutee-450e | Le DevOps fusionne le développement (Dev) et les opérations (Ops) pour harmoniser les équipes, les processus et la technologie dans la planification, le développement, la livraison et l'exploitation des applications. Cette approche favorise la coordination et la collaboration entre des fonctions qui étaient auparavant séparées, telles que le développement, les opérations informatiques, l'ingénierie de qualité et la sécurité.
Les équipes adoptent la culture, les pratiques et les outils DevOps pour renforcer la confiance dans les applications qu'elles conçoivent, mieux répondre aux besoins des clients, et atteindre plus rapidement leurs objectifs commerciaux. DevOps aide les équipes à offrir continuellement de la valeur aux clients en proposant des produits de meilleure qualité et plus fiables.
La collaboration au sein des équipes DevOps représente l'un des défis les plus complexes que j'ai pu rencontrer au cours de mes expériences, en tant que professionnel de l’informatique. Tout commence à partir du processus de recrutement, au cours duquel les recruteurs disposent d'une longue liste de critères à évaluer basée sur la maîtrise d’outils. Ensuite, le management privilégie généralement les ingénieurs ayant fait le plus de missions (vous noterez que je n’ai pas dit expérimenté, je reviendrais dessus), certifiés, ou ayant validé de nombreux projets. Pour finir, les compétences techniques semblent se résumer à la maîtrise d’une liste d’outils et semblent prendre le pas sur la compréhension intégrale d’un système d’information, des qualités humaines, d’apprentissages et de collaboration qui font partie intégrante des compétences d’un excellent DevOps, lors des recrutements au sein des équipes et des entreprises.
En effet, selon l'Alliance Agile afin de garantir une transformation DevOps fructueuse, il est crucial, que les membres d'une équipe possèdent des qualités spécifiques. Ils doivent ainsi être proactifs, capables d'anticiper les changements, démontrer une capacité à innover, et posséder une connaissance approfondie de l'organisation et des processus de l'entreprise. Cependant, de nos jours, l'accent est davantage mis sur la connaissance des outils DevOps, ce qui conduit à une vision réductrice de ce qu'implique le rôle d'ingénieur DevOps. L’ingénieur DevOps devient un expert en outils DevOps. Les conséquences de cette approche sont diverses. Par exemple, un ingénieur avec une approche outil, a souvent tendance à adapter le problème à son outil, ce qui n’a absolument pas de sens. Cet ingénieur voudra à tout prix utiliser des outils qu’il maîtrise quel que soit la mission, au détriment de la performance et parfois de la cohésion des équipes. De plus les outils DevOps sont divers, et pour un même problème il existe divers outils. Le prototype du bon DevOps est d’analyser le problème, de trouver une solution avant de trouver l’outil adapté qui satisfait les exigences de l’entreprise, la cohésion de l’équipe et le gain financier. | medgardherv | |

These tools also incorporate keywords, metadata and other SEO best practices, which also improves the visibility of the content for technical writers. This optimization enhances user experience and drives traffic to the content.
## Reduced Costs and Time spent
By using AI tools, technical writers save themselves a lot of time and effort that would be required to create and publish technical content. This saves cost and allows writers publish content for their audience at a faster rate.
These are just some of the ways in which AI has helped technical writers create high quality content more efficiently and effectively. By using these tools, writers can deliver top quality content and increase their audience size.
## Challenges of AI in Technical Writing
Despite the fact that artificial intelligence offers numerous benefits, it still has some challenges that are associated with its use. Some of these challenges include;
## Accuracy and Quality
Even though these tools can quickly generate content, they don't always produce high quality and accurate content. As a result of this, technical writers must be really careful not to completely rely on the content generated due to the fact that AI relies on data and sometimes the data isn't accurate. Inaccuracies in the data will affect the quality of the content and reduce user satisfaction. Technical writing requires a high level of accuracy, so ensuring that AI-generated content meets these standards can be a huge challenge.
## Data Privacy
It is a known fact that artificial intelligence relies on large amounts of data to function and work very well. Although this data is beneficial, it raises concerns about the privacy of the data being used. Therefore, writers should be mindful of sensitive information that could be added to their content and make sure to protect it from unauthorized access, misuse or misinterpretation. Abiding with data protection regulations is key when using AI tools for content generation.
## Skill Upgrade
As this technology continues to advance, some technical writers would need to upskill and adapt to it. Unfortunately, the learning process can be quite challenging for some professionals who are already used to the traditional methods of technical writing, making it hard for them to stay up to date and keep up with the changes in the industry.
## Bias and Fairness
Since AI tools rely on data, there might be bias in the data that they were trained on and if the training data contains bias or unfair information, it will affect the content generated. This is an issue because in technical writing, accuracy and conciseness are very important. So ensuring that AI-generated content is free form bias can a be a big challenge for writers.
## Bad User Experience
Technical writing usually requires human touch and empathy to produce content for specific audiences or situations but artificial intelligence might struggle to provide this level of empathy needed to create a positive user experience. As a result of this, some users might find AI-generated content difficult to understand therefore it seems boring to them.
Though AI can be a valuable tool in technical writing, it is important to be aware of these challenges and how they should be addressed in order to ensure the quality of technical content.
## Future of AI in Technical Writing
With the advancements in AI, its impact on technical writing will only continue to increase. Here are some of the potential advancements in AI that we could see in the future.
## Augmented Reality Integration(AR)
Artificial intelligence with the use of AR can improve technical documentation by displaying digital information onto physical objects providing users with an interactive way of learning.

Ever spent hours troubleshooting colors on an external CSS styling only to notice that the colors haven’t been rooted ? That was me when I began my coding journey. Let's explore my transformation from a web dev novice to a confident Frontend developer.
Since a little boy, I have been fascinated with seeing people in movies being dead serious on their computer running set of green codes In act of hacking or bypassing something which really sparked that zeal for this coding field.
My journey began after my Junior WAEC in a web development bootcamp, where I was exposed to other coding careers than hacking , there I weighed the income and stress I will get pursuing any of the coding careers . I won’t say I did not know this decision would lead to immense growth and discovery.
So, I started with the knowledge from the web development boot camp I joined after my junior WAEC , online platforms with vast courses like the W3schools and supplemental resources like Ai, which I use till this day and will continue using .
Despite initial excitement, difficulties emerged when encountering complex concepts like DIV and CSS styling, but now I am confident of handling them and have at least 85% strength to overcome those concepts because of the things I learnt and still learning as I undergo my Industrial training in the White Hat tech firm.
So far during my industrial training,
I have built 3 simple web pages using HTML, CSS, and will be doing more which will require Java, solidifying my front-end development understanding and give me a kick start for java script and React.
Moreover,
Debugging challenges and simple oversights taught me the importance of perseverance and taking breaks to clear my mind at times ,listening to music was a big support for me too.
God willing,
as a soon to be confident Frontend developer and Full-stack developer in couple of months ,I plan to learn new programming languages like React and Dart for flutter, because I am chasing being an App and Software developer with a goal of starting a tech fund or a Multinational Technology ,and helping mentor new coders as I am being mentored today.
In conclusion,
My coding journey has been transformative, filled with trials and triumphs. Embracing challenges, seeking help, and celebrating milestones as I embark on more through my coding journey. Thank You .

Discover its unique strengths and uncover any limitations, alongside effective strategies to overcome them. Embark on a journey of exploration and empowerment with us!
## What is AutoModelForCausalLM?
AutoModelForCausalLM is a class within the [Hugging Face](https://blogs.novita.ai/top-10-llm-models-on-hugging-face/) Transformers library, a widely-used open-source Python library for working with pre-trained natural language processing (NLP) models. This class is specifically designed for causal language modeling tasks.
### Auto+Model+Causal+LM
The "Auto" prefix in the class name indicates that it can automatically handle the process of selecting the appropriate model architecture based on the user's requirements, abstracting away the complexity of model instantiation.
The "Model" component refers to the underlying transformer-based neural network architecture that powers the language modeling capabilities. In this case, the model is specifically tailored for "Causal" language modeling, which means it generates text in a unidirectional, left-to-right manner, predicting the next word in a sequence based on the preceding context.
The "LM" abbreviation stands for "Language Model", highlighting the core purpose of this class - to understand and generate human-like text. Causal language models like AutoModelForCausalLM are commonly used for tasks such as text generation, language translation, and dialogue systems.
### Unidirectional, not bidirectional
Compared to other transformer model types, the key difference in AutoModelForCausalLM is its unidirectional nature. This means it processes the text in a one-way, left-to-right fashion. Imagine you're reading a book - when you read a sentence, you start from the beginning and work your way through to the end. You don't jump around or read the sentence backwards. That's the same principle behind the unidirectional nature of AutoModelForCausalLM.
The model looks at the words that come before the current word, and uses that context to predict what the next word in the sequence will be. It doesn't look at any information that comes after the current word. This is different from bidirectional language models, like BERT, which can consider the entire input sequence when making predictions. Bidirectional models have access to the context both before and after the current word, giving them a more holistic understanding of the text.
## How Does AutoModelForCausalLM Work?
### The Autoregressive Modeling Approach
The core idea behind Automodelforcausallm is to use an autoregressive modeling approach to infer causal relationships from observational data. Autoregressive models are statistical models that predict the future value of a variable based on its past values. In the context of causal inference, these models can be leveraged to understand the conditional dependencies between variables.
### Modeling Observational Data
The first step in the Automodelforcausallm framework is to take the observed data - the measurements and recordings of the variables in the system - and use that to train an autoregressive model.
An autoregressive model is a type of statistical model that can predict the future value of a variable based on its past values. So for example, it could learn that variable A at time t depends on the values of variables A, B, and C at previous time points.
By training this autoregressive model on the observational data, it can learn the underlying patterns and relationships between all the variables in the system. The model essentially captures the conditional probability distributions - how the variables depend on and influence each other.
### Simulating Interventions
After the autoregressive model is trained on the observational data, the next step is to simulate what would happen if we actively changed or intervened on certain variables in the model.
For example, let's say the model has learned that variable A influences variable B. To simulate an intervention, the model will deliberately change the predicted value of variable B, as if we had manually intervened and set B to a different value.
By comparing the model's predictions with and without this intervention on B, the framework can determine how much the outcome changes. This allows the model to infer the causal effect - the impact that manipulating variable B has on the other variables.
In other words, the model is mimicking real-world interventions or experiments, but doing so computationally within the autoregressive framework. This lets the model uncover causal relationships without actually having to intervene in the real world.
## The Advantages of AutoModelForCausalLM
### Edges over Traditional Approaches
**1. No Causal Graph Assumptions**
Traditional causal inference methods often require you to make assumptions about the underlying causal structure of the data. This means you have to draw a causal graph showing how the different variables are connected. In contrast, the Automodelforcausallm approach does not need any of these additional causal graph or structural assumptions. It can infer causality without requiring you to guess the right causal model upfront.
**2. Flexible Autoregressive Modeling**
The Automodelforcausallm framework uses autoregressive modeling, which is a very flexible statistical technique. This flexibility allows the model to consider complex, nonlinear effects between the variables. It can capture intricate relationships that may not be easily represented by simple linear models or causal graphs.
**3. Handles High-Dimensional Data**
Additionally, the autoregressive modeling used in this approach can work with data that has a large number of variables or features (high-dimensional data). This is important because many real-world applications involve complex datasets with lots of different factors and measurements. The Automodelforcausallm framework can handle this complexity.
### Applicability to Dynamic Environments
Another notable aspect of Automodelforcausallm is its ability to be extended to dynamic environments, such as time series data. This allows the framework to perform causal inference in settings where the relationships between variables may evolve over time, expanding the scope of its applicability.
Specifically, the framework leverages autoregressive and vector autoregressive (VAR) models, which are powerful tools for capturing temporal dependencies and evolving relationships within complex, multivariate data.
The autoregressive structure of these models allows them to account for how a variable's current state is influenced by its own past values. This is crucial for modeling dynamic systems where the present is shaped by historical trends and patterns. By incorporating lagged terms of the dependent variables, the Automodelforcausallm approach can effectively uncover and quantify these time-varying relationships.
Furthermore, the VAR extension enables the simultaneous modeling of multiple interrelated time series. This makes the framework well-suited for high-dimensional, interconnected datasets - a common characteristic of dynamic real-world systems like financial markets and climate phenomena.
## Applying AutoModelForCausalLM
### How to Use AutoModelForCausalLM in codes?
1 Install the Transformers library
```
pip install transformers
```
This is a comment indicating that you need to install the Transformers library using pip, a package manager for Python. This library contains tools and pre-trained models for natural language processing tasks.
2 Import necessary modules
```
from transformers import AutoModelForCausalLM, AutoTokenizer
```
This line imports two specific modules from the Transformers library:
`AutoModelForCausalLM`: This module allows us to load a pre-trained causal language model. Causal language models can generate text based on a given prompt or context.
`AutoTokenizer`: This module allows us to load a pre-trained tokenizer. Tokenizers break down input text into individual tokens, which are the basic units that the model understands.
3 Load the pre-trained tokenizer and model
```
tokenizer = AutoTokenizer.from_pretrained("gpt2")
model = AutoModelForCausalLM.from_pretrained("gpt2")
```
These lines load a pre-trained tokenizer and model from the Transformers library. Specifically, they load the GPT-2 tokenizer and GPT-2 model.
4 Encode the input text
```
input_text = "I want to learn AI"
input_ids = tokenizer(input_text, return_tensors='pt').input_ids
```
This code encodes the input text "I want to learn AI" using the tokenizer. The tokenizer converts the input text into a sequence of token IDs, which the model can understand. The `.input_ids` part extracts the token IDs from the tokenizer's output and stores them in the `input_ids` variable.
5 Generate text
```
generated_ids = model.generate(input_ids, max_length=30)
```
This line generates text based on the input token IDs using the pre-trained model. The `generate` method produces new text given a starting prompt or context. Here, `input_ids` serves as the starting point for generating text, and `max_length=30` specifies that the generated text should be at most 30 tokens long.
6 Decode the generated text
```
generated_text = tokenizer.decode(generated_ids[0], skip_special_tokens=True)
```
This code decodes the generated token IDs back into human-readable text using the tokenizer. The `decode` method converts the token IDs into words, producing the final generated text. The `skip_special_tokens=True` argument ensures that any special tokens (like end-of-sequence tokens) are excluded from the decoded text.
7 Print the generated text
```
print(generated_text)
```
This line prints the generated text to the console, allowing us to see the output of the model. It displays the text generated based on the input prompt "I want to learn AI" according to the language patterns learned by the GPT-2 model.
```

### What tasks can AutoModelForCausalLM do in real life?
The Automodelforcausallm framework can be quite powerful when applied to dynamic environments like financial markets or climate systems.
In the financial domain, the relationships between different economic and market variables are often highly complex and time-varying. Stock prices, interest rates, commodity prices, and macroeconomic indicators can all influence each other in intricate, nonlinear ways that evolve over time.
The Automodelforcausallm approach would be well-suited to uncover these dynamic causal connections. By modeling the autoregressive, time-series nature of financial data, the framework could identify how shocks or changes in one variable ripple through the system and impact other variables, even as those linkages shift over time. This could provide valuable insights for investors, policymakers, and researchers trying to understand the true drivers of financial market behavior and trends.
Similarly, in climate science, there are complex, nonlinear relationships between factors like temperature, precipitation, greenhouse gas emissions, ocean currents, and various other environmental variables. And these causal connections are often highly dynamic, evolving over time in response to both human activity and natural cycles. Applying the Automodelforcausallm framework to climate data could help reveal how the influence of different climate drivers changes across seasons, years, or decades. This could lead to improved climate modeling, better projections of the impacts of climate change, and more targeted policy interventions.
## Limitations of AutoModelForCausalLM
The main limitations of Automodelforcausallm are its data requirements, complexity, and inherent assumptions. The approach needs extensive time series data to work effectively, which may not always be available. As the models become more sophisticated to handle dynamic, nonlinear relationships, they can also become highly complex, making the results less interpretable.
Additionally, while Automodelforcausallm can accommodate some nonlinearity, it is still fundamentally based on linear modeling techniques, which may not fully capture highly nonlinear or discontinuous systems.
Finally, while Automodelforcausallm can uncover evolving causal patterns, it may struggle to definitively determine causal directionality in some cases.
## Overcoming AutoModelForCausalLM's limitations
It is unavoidable that one type of model performs well in certain tasks but not ideally in others. What's more, GPU maintenance is another realistic factor to consider when running models on your own devices. Therefore, integrating APIs for LLMs with different capabilities into whatever you are building may be a good idea.

In this blog post, we will delve into the core differences between KYC and AML, exploring their unique roles, processes, and importance in safeguarding the financial system. This information will be helpful for financial professionals and business owners, as understanding the distinctions between KYC and AML is essential for navigating today's complex financial environment.
## What is KYC?
KYC (Know Your Customer) is a crucial process by which businesses verify the identity of their customers to prevent money laundering, identity theft, financial fraud, and terrorism financing. The primary goal of KYC is to ensure that customers are who they claim to be, thereby reducing the risk of financial crimes. This verification process typically involves the use of government-issued documents, such as a driver's license or passport, to confirm both identity and address.
The KYC process serves multiple purposes, including combating money laundering, preventing terrorist financing, and curbing tax evasion. Financial institutions and businesses collect and verify customer identity documents, ensuring that the information provided is accurate and legitimate. The specific data required for verification is often determined by the policies of the exchange platform or financial institution.
There are two main approaches to verifying customer identities: manual and automated.
Manual KYC involves an in-person meeting with a company representative to verify identity through physical inspection of documents. This method, while thorough, can be time-consuming and resource-intensive.
Automated KYC systems, on the other hand, utilize advanced technologies to verify identities remotely, offering efficiency and scalability. Key technologies used in automated KYC include Optical Character Recognition (OCR), Machine Learning (ML), Biometric Verification.
So, in summary, KYC is a process used by businesses, particularly in the financial industry, to verify the identity of their clients. It involves collecting and assessing various forms of identification and personal information to ensure that customers are who they claim to be.
## What is AML?
Anti-Money Laundering (AML) refers to the set of laws, regulations, and procedures implemented by financial institutions and regulatory bodies to detect, prevent, and report money laundering activities. Money laundering is the process of making illegally obtained money appear legitimate, often by funneling it through various financial transactions to disguise its origins.
AML efforts are crucial for maintaining the integrity of the financial system. By implementing the measures, financial institutions help prevent the funding of illegal activities, such as terrorism, drug trafficking, and corruption. Moreover, robust AML practices protect the institutions themselves from legal and reputational risks associated with being involved, knowingly or unknowingly, in money laundering schemes.
Governments and international organizations play a key role in setting AML standards and regulations. Agencies such as the Financial Action Task Force (FATF) develop global policies to combat money laundering and promote the effective implementation of legal, regulatory, and operational measures. Compliance with AML regulations is not just a legal obligation but also a critical component of global financial security and stability.
**AML regulations require financial institutions to:**
- Maintain records. Keep detailed records of transactions to create an audit trail.
- Report specific transactions. Disclose certain transactions to government agencies, especially those that appear suspicious.
- Conduct due diligence. Perform thorough checks on customers to verify their identities and assess the risk they pose.
In summary, Anti-Money Laundering (AML) encompasses a comprehensive framework aimed at identifying, preventing, and reporting money laundering activities. Through diligent monitoring, reporting, and compliance, financial institutions contribute to a safer and more transparent financial system.

I’m still at the early stages of my tech career and I have faced numerous challenges, from deciding on the path to follow to dealing with the low teaching standards at my school.
My tech journey began during my second year in the university when we took an introductory course in programming called CMS 200. We learnt C++; it was very challenging.
The journey wasn’t smooth. The school I attend have poor teaching standards. We wrote codes on the board rather than a compiler. We weren’t even making use of the computer lab to put into practice on the things we were being taught, it was just theory all through. This left me feeling underprepared and frustrated.
Choosing a specific path in tech was one of the most challenging decisions I faced. The tech world is very wide with numerous fields such as data science, cybersecurity, app development, web development etc. Each seemed interesting in its own way and I was overwhelmed by the options.
After much contemplation, I decided to focus on web development. The ability to create interactive and dynamic websites for organizations and people which could be used worldwide was appealing to me.
I am currently in my fourth year in the university and I took advantage of my IT in my fourth year to learn web development at White creativity. I have been able to do some work using HTML and CSS, various materials are made available to us, to aid learning.
I am still at the beginning of my journey in web development and still working on improving my skills. I am excited about the path ahead and eager to continue growing in this field.

Aquest vehicle, d'escala 1/18, pot ser entrenat per conduir-se a si mateix utilitzant models d'aprenentatge per reforç que es desenvolupen i s'avaluen en un entorn de simulació tridimensional proporcionat per AWS.
**Components Principals**
Consola AWS DeepRacer: És una interfície gràfica d'usuari que permet als desenvolupadors crear, entrenar i avaluar models d'aprenentatge per reforç. La consola facilita la creació de treballs d'entrenament on es defineixen funcions de recompensa, algoritmes d'optimització, entorns de simulació i hiperparàmetres.
Vehicle AWS DeepRacer: Es tracta d'un vehicle físic equipat amb un mòdul de computació capaç d'executar inferències utilitzant models entrenats. Aquest vehicle es connecta a internet per descarregar el programari necessari i permet l'accés a la consola del dispositiu per operar-lo mitjançant un ordinador o dispositiu mòbil.
Lliga AWS DeepRacer: Una competició global d'automobilisme autònom on els participants poden competir per premis i reconeixement. Aquesta lliga proporciona un entorn per comparar habilitats en aprenentatge automàtic amb altres desenvolupadors.
**Aprenentatge per Reforç**
L'aprenentatge per reforç (AR) és un mètode d'aprenentatge automàtic que es basa en la presa de decisions autònomes per part d'un agent per assolir objectius específics mitjançant interaccions amb l'entorn. En el context de l'AWS DeepRacer, l'agent és el vehicle, i l'entorn és la pista de conducció. Els agents reben recompenses per prendre accions que els porten a assolir els seus objectius de manera eficient.
**Espai d'Accions i Funció de Recompensa**
L'espai d'accions defineix totes les accions possibles que un agent pot realitzar en cada estat de l'entorn. AWS DeepRacer permet entrenar agents en espais d'accions discrets o continus. La funció de recompensa és clau, ja que incentiva l'agent a realitzar accions que augmentin la seva recompensa total a llarg termini. Un exemple senzill seria recompensar el vehicle per mantenir-se al centre de la pista i penalitzar-lo per sortir-se'n.
**Algoritmes d'Entrenament**
AWS DeepRacer utilitza principalment dos algoritmes d'aprenentatge per reforç:
Proximal Policy Optimization (PPO): Un algoritme d'aprenentatge on-policy que aprèn una funció de valor basada en les observacions de l'entorn fetes per la política actual.
Soft Actor-Critic (SAC): Un algoritme off-policy que pot utilitzar observacions fetes per polítiques anteriors, maximitzant l'entropia per equilibrar l'exploració i l'explotació.
**Flux de Treball**
El procés d'entrenament amb AWS DeepRacer implica:
Inicialitzar la simulació amb una pista virtual, un agent i un fons.
L'agent pren accions basades en l'estat de l'entorn.
L'entorn simulat actualitza la posició de l'agent i retorna una recompensa.
El model de xarxa neuronal es guarda periòdicament.
L'entrenament s'atura després d'un límit de temps especificat.
Avaluar el model entrenat en un entorn simulat per verificar-ne el rendiment.
Després de l'entrenament, el model -si s'escau- es pot descarregar i desplegar al vehicle físic AWS DeepRacer per a proves en un entorn real.
**Reducció de la Bretxa Sim2Real**
Un dels reptes principals és la discrepància entre el rendiment del model en simulació i en el món real. AWS DeepRacer aborda aquesta bretxa mitjançant l'alineació de les freqüències d'acció i inferència entre l'agent simulat i el vehicle físic, així com la variació aleatòria de la posició inicial de l'agent durant l'entrenament per assegurar una cobertura uniforme de la pista.

As organizations grow and transform, EA strategy acts as a guide during continuous technical change, helping improve operational, cost, and strategic efficiencies to meet business objectives. This article provides best practices, challenges, and solutions to help organizations develop a robust EA strategy.
##What is enterprise architecture strategy?
Enterprise architecture strategy refers to the overall plan that merges business goals with technical systems and infrastructure. It provides a roadmap for how different resources—including data, applications, and infrastructure—connect and support business objectives.
Given the rapid pace of change facing many industries, a sound EA strategy is crucial to enabling innovation and staying competitive. It gives organizations a framework for establishing a technical culture and infrastructure that can adapt to a changing business landscape.
Since EA strategy sits at the intersection of business and technology, it needs to take into account broad organizational goals and tactics. An effective EA strategy merges knowledge of legacy systems and constraints with emergent technological trends to support overarching business objectives.
##Aligning business and technology
A key component of EA strategy is aligning business goals with technology systems and infrastructure. This ensures that technology initiatives like adopting new tech stacks ultimately serve business goals such as improved customer engagement, higher ROI, and expanded market share.
Here are some best practices for keeping EA strategy in sync with business goals:
- Document business goals, requirements, and constraints
- Map goals to specific workflows, applications, data, and infrastructure resources
- Identify knowledge gaps in enterprise architecture
- Implement governance for decision-making and accountability
- Create feedback loops to continuously improve EA strategy
##Key components of EA strategy
The strategic goals of executives, IT personnel, product teams, and other stakeholders come together to form an EA strategy. Some key components include the following:
###Governance
Governance establishes the processes, policies, roles, and decision-making authority necessary to realize the EA strategy. It provides oversight and accountability for strategy execution. Governance may involve committees, working groups, or councils with representation from both business and technology units.
###Methodology
Methodology provides established frameworks and workflows to create, manage, and analyze EA artifacts consistently. Methodologies like TOGAF help organize architectural development and decision-making. Following a standard methodology improves quality and aligns strategy outputs.
###Technology
Technology facilitates the creation of the systems, infrastructure, and software needed to accomplish EA strategy goals. This includes platforms for modeling system architecture, analytics tools for data-driven insights, and collaboration software for stakeholder participation.
###People
Team members bring the skill sets and experience that make EA initiatives a reality. Enterprise architects translate business needs into technical vision and strategy. Developers and engineers build and implement the architectures. Stakeholders provide the business context and validate strategy alignment.
People and processes are as important in EA strategy as the technologies they use. The culture that arises from these core elements enables the planning, execution, and realization of impactful change.
##Modernizing enterprise architecture
Modern software development practices emphasize agility and adaptability, often challenging traditional EA practices. Bridging this gap requires integrating agile methodologies into EA strategies. While there is no one-size-fits-all approach, there are several methods to consider:
###Consider the enterprise architect as a bridge
A key benefit of EA is aligning short-term deliverables with long-term goals. Rather than acting exclusively as managers focused on high-level system design, enterprise architects collaborate directly with developers and act as bridges between teams and executives.
###Align architecture with engineering
A common problem occurs when system design decisions are made without implementation insight. Ensure that EA decisions are made by individuals with direct software development experience or in close collaboration with engineering teams.
###Keep architecture lean and modular
Rather than planning an entire complex system up front, focus architectural decisions on key elements, tradeoffs, and flexibility to enable iterative development while keeping intact core components to avoid major redesign costs.
###Establish cross-functional teams
Create teams with architects, developers, and business stakeholders in early planning to improve decisions, align with business goals, and set realistic timelines for deliverables.
###Embrace architecture as a shared responsibility
Recognize architecture as a shared duty, not the sole responsibility of designated architects. This can mean seeking more input from developers on EA decisions and ensuring accessibility of EA artifacts across the organization.
The goal of these practices is to incorporate diverse views to arrive at more holistic decisions that serve business needs and development realities. Adopting agile tools and practices helps enterprise architects collaborate effectively with stakeholders.
##Conclusion
Enterprise architecture strategy plays a critical role in aligning business and technology within an organization. As a bridge between executive leadership, IT infrastructure, and software development teams, EA strategy provides a roadmap for how systems, data, and processes work together to achieve strategic goals.
An effective EA strategy requires participation from stakeholders across the business and technology units. Governance, methodology, tools, and culture all influence how well EA strategy translates vision into reality.
As software development trends toward agility, adaptability, and speed, enterprise architecture also needs to evolve. Integrating agile practices through cross-functional teams, modular architectural decisions, and recognizing architecture as a shared responsibility helps bridge traditional EA approaches with modern ways of building technology.
With the right strategy and participation, enterprise architecture enables businesses to innovate quickly while maximizing return on technology investments. As industries and technologies continuously transform, a sound EA strategy acts as the compass guiding an organization successfully into the future.

1,879,055 | Bitcoin Back in the Game: Will It Succeed Above $71K? | Bitcoin grips above $71,000 amid high ETF demand. Is speculative interest back? On June 5,... | 0 | 2024-06-06T10:15:23 | https://dev.to/endeo/bitcoin-back-in-the-game-will-it-succeed-above-71k-ped | webdev, javascript, web3, blockchain | #### Bitcoin grips above $71,000 amid high ETF demand. Is speculative interest back?
On June 5, sluggish Bitcoin dynamics switched to an abrupt volatility which paved the way to $71,540 at the writing time.
The uptick kicked in as the positive two-week exchange-traded funds (ETFs) collective netflow hit the record $886.75 million on June 4, mainly driven by Fidelity’s FBTC’s $379 million inflows.
Reacting to the massive inflows, Bloomberg analyst Eric Balchunas cited ones to be a “tidal wave”.
“Fidelity not messing around, big-time flows all around today for The Ten, nearly $1b in total. Second best day ever, since Mid-March. $3.3b in past 4wks, net YTD at $15b (which was top end of our 12mo est). The 'third wave' is turning into tidal wave,” – he wrote in a post for X.
BlackRock’s IBIT also racked up substantial inflows on Tuesday, netting $274 million. Specifically, BlackRock possessed 291.5K Bitcoin’s as of June 3, which was an equivalent to over $20 billion dollars as per market prices back in the day.
ARK Invest’s ARKB stood out as well, collecting nearly $139 million of BTC.
## Is Bitcoin Reached to ATH?
Decent metrics seemed to have brought speculative interest in Bitcoin back. One has recessed amidst Bitcoin’s robust dynamics, which prevailed over the last two weeks and forced market participants to seek volatility in memecoins and gaming tokens.
As the on-chain data reveals positive sentiment probability, Willy Woo took it further, claiming that Bitcoin is poised for updating its all-time high (ATH).
According to the crypto analyst, reaching the level of $72,000 will act as a “fuse”, triggering the breakthrough of the $75,000. Such price action would also spur a wave of liquidations and pave the way to a new historical maximum.
“Tapping 72k is the fuse that's set to start a liquidation cascade. $1.5b of short positions ready to be liquidated all the way up to $75k and a new all time high,” Woo wrote in a post for X.
This outlook seems agreeable to HODL15 Capital, an entrepreneur and analyst. In his post for X, he stated that the $74,000 was feasible due to the “lack of sell walls” on order books across major exchanges.
Still, the probability of Bitcoin achieving a $74,000 price range comes with an array of conditions.
According to RektCapital, a renowned market analyst, Bitcoin needs to turn the $72,000 resistance into support in order for it to enter a parabolic phase of the bull cycle,
“Bitcoin just needs to break this final major resistance area (red) to enter the Parabolic Phase of the cycle”
Before this, RektCapital noted that Bitcoin has broken out of a two-week downtrend on June 3, hinting at the bullish sentiment for the first cryptocurrency.
“Bitcoin broke its two-week downtrend today. However, we have seen upside wicks beyond this downtrend before. Which is why a Daily Close later today is needed to confirm this breakout,” the analyst stated in a post on X.
Meanwhile, macroanalyst TedTalksMacro suggested that Bitcoin’s move above $74,000 could be confirmed after the May US employment data, scheduled for June 7,
“...with inflation under control, the market's focus will now turn to employment data - which is the other 50% of the Fed's mandate.”
## Chart Reveals Bullish Sentiment
Bitcoin’s chart analysis corelates with an optimism, demonstrated by on-chain data.
As per 1-day chart, the price has been tested to the higher boundary of the descending channel and the $69,000 resistance level. If Bitcoin breaks out of the zone further north, the market has all chances to run toward the $75,000 and even create a new ATH.
The relative strength index (RSI) stands at 63, which proves the bullish momentum in a long-term perspective and hints at a potential upward rally.
In the 4-hour chart, Bitcoin’s price has struggled to keep above the $69,000 resistance level and has been consolidating inside a symmetrical triangle pattern. Still, as the higher trendline of the pattern has been broken with a recent uptick, the chart may signal a further continuation of the bullish sentiment.
Nevertheless, if the price drops back inside the triangle pattern, a decline to $60,000 is possible.
While the bullish scenario for Bitcoin seems more likeable, traders should watch out for the increased volatility and speculative interest. | endeo |

1,879,053 | Automatically bypass Normal Captcha Types | In the modern digital landscape, security is paramount. One of the key tools used to ensure security... | 0 | 2024-06-06T10:15:03 | https://dev.to/media_tech/automatically-bypass-normal-captcha-types-3o61 | In the modern digital landscape, security is paramount. One of the key tools used to ensure security online is CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart). These tests are designed to determine whether the user is a human or a machine. The concept is simple yet incredibly effective, making CAPTCHAs an essential component of internet security. This article delves into the specifics of what a normal CAPTCHA is and how you can solve it using various CAPTCHA solvers.
**Understanding CAPTCHAs**
**What is a CAPTCHA?**
A CAPTCHA is a challenge-response test used in computing to determine whether or not the user is human. This mechanism helps prevent automated bots from accessing websites and performing actions that can be harmful or spammy. CAPTCHAs come in many forms, including distorted text, image recognition, and simple math problems.
**Types of CAPTCHAs**
**Text-Based CAPTCHAs:** These are the most common type of CAPTCHAs. Users are required to enter the characters they see in a distorted image.
**Image-Based CAPTCHAs:** These require users to identify and select images based on a prompt, such as "Select all images with traffic lights."
**Solving Normal CAPTCHAs**
**Using CAPTCHA Solvers**
For those needing to solve CAPTCHAs more efficiently, CAPTCHA solvers can be an invaluable tool. CAPTCHA solvers use various techniques to automate the solving process, making it faster and less tedious for users. There are several types of CAPTCHA solvers available:
**Automated Software:** These programs use advanced algorithms and optical character recognition (OCR) to decode and solve CAPTCHAs.
**Online CAPTCHA Solvers:** Websites that offer CAPTCHA solving services. Users upload the CAPTCHA image, and the site provides the solution.
**Browser Extensions:** Plugins or extensions that can automatically solve CAPTCHAs as you browse the web.
**How CAPTCHA Solvers Work**
CAPTCHA solvers typically function by either using OCR technology to read and interpret the CAPTCHA or by employing human solvers who manually solve the CAPTCHA and provide the answer. Here’s a brief overview of how these methods work:
**Optical Character Recognition (OCR):** OCR technology scans the CAPTCHA image, recognizes the text, and converts it into machine-readable characters. This method works well for text-based CAPTCHAs but can struggle with heavily distorted images.
**API Integration:** Many CAPTCHA solvers offer APIs that can be integrated into your applications. When a CAPTCHA is encountered, the image or challenge is sent to the service, and the solution is returned via the API.
**Benefits of Using CAPTCHA Solvers**
**Time Efficiency:** Automating the CAPTCHA solving process saves time, especially for tasks requiring the completion of numerous CAPTCHAs.
Accuracy: Professional CAPTCHA solvers have high accuracy rates, reducing the chance of errors.
**Convenience:** Integrating CAPTCHA solvers into your workflow can streamline processes that involve frequent CAPTCHA challenges.
**Best Practices for Using CAPTCHA Solvers**

1,879,051 | Build a consistent Style API for Angular Components | While creating a new component library for an ERP-System, we invested a bit of time to rethink how we... | 0 | 2024-06-06T10:13:15 | https://dev.to/gregonnet/build-a-consistent-style-api-for-angular-components-4l82 | While creating a new component library for an ERP-System, we invested a bit of time to rethink how we want to make styling of components easier than before.
Of course, nearly every Component library offers a way of creating themes. Nevertheless, there are special requirements that afford a style-override that absolutely fits in the design, but is not part of the library at this point in time.
Possibly, you want to slightly adjust a colour or spacing.
Perhaps, you wish to be able to use another template for a list-item inside a component, but the Component's API does not allow you to.
## 🕺🏻 The “CSS Override Dance”
In order to solve our design-challenge, we used to…
1. … find the HTML-Element in the respective Component that requires styling.
1. … inspect the Element to determine which CSS class requires an override.
1. … come up with the correct CSS-override.
In the past, our team used the following ways to override Component Styles:
1. Adding another CSS class that can be appended to the Component's Host-Element itself
1. Overriding an existing CSS class by turning off _ViewEncapsulation_
1. Using [::ng-deep](https://angular.dev/guide/components/styling#ng-deep)
1. Playing with the [!important-Rule](https://www.w3schools.com/css/css_important.asp).
1. If provided, using a Hook of the Component library to override styles (e.g. [PrimeNG](https://primeng.org) provides the _input()/@Input()_ styleClass for lots of their components).
1. In exceptional cases, we have re-implemented the component for our needs. 🤫
To be honest, we are not happy working like this.
## The Problem
- Most of the time, we came up with a different approach for overriding styles that need to be explained to fellow team members
- We had to invest more time in finalizing a feature than expected due to the additional workload to customize a component.
- Once the Component library received a major update, our overrides do not work any more, due to breaking changes.
- Custom Style-APIs like PrimeNG's _styleClass_ help, but aren't consistently applied everywhere. Sometimes it works, sometimes not.
## The aim
- Instead of trying out different ways of customizing a Component, we want **one clear API**, that is easy to use for everybody in the team.
- This API should be consistent across all components.
- Ideally, we can stick with the web-standards.
- Provide a Style-API for our teammates, allowing them to customize our Components with ease.
## Inspiration
### QwikUi
> https://qwikui.com/
We started looking for alternative solutions. We were surprised to see, that style overrides are a very common and simple thing to do in Frameworks using [JSX](https://react.dev/learn/writing-markup-with-jsx).
```tsx
export const Label = component$<LabelProps>((props) => {
return (
<HeadlessLabel
{...props}
class={cn(
'font-medium peer-disabled:cursor-not-allowed peer-disabled:opacity-70',
props.class,
)}
>
<Slot />
</HeadlessLabel>
);
});
```
[Source: Qwik UI](https://github.com/qwikifiers/qwik-ui/blob/13e0d53a7b0debceb2e41a01dcca02bb6aca0b61/packages/kit-styled/src/components/label/label.tsx#L11)
The snippet demonstrates the class-overrides can simply be passed down the Component-Tree. Provided CSS classes can be merged dynamically based on certain conditions.
💫 Our team was excited by the fact that styling can be done using Web-Standards without workarounds.
### Angular Material
> https://material.angular.io/
Now, it was our turn to try if we can come up with a solution in Angular. We were wondering if we can come up with a clean solution by manipulating the _class_-Attribute of the Component's host element. In our experience, this approach is not widely used, but we remembered that we have seen this in _Angular Material_ components.
That's why we started looking at the implementation and gained confidence to go with the Host-Binding-Approach. Nearly every component in Angular Material specifies host-classes (see [MatFabButton](https://github.com/angular/components/blob/main/src/material/button/fab.ts#L66)).
## Our consistent Component-Style-API
We do not consider to have found the silver bullet yet. We just want to share our findings with you and are **happy to receive feedback** in order to check if we are on the right path or if we might consider other ways.
### Style-API Rules
1. We provide basic styling, to allow the team to use the Components right away.
1. Every developer can customize each Component using the `class`-Attribute.
1. We agree on a standardized way of applying CSS classes to be able to optimize them, behind the scenes.
### 👩🏻💻 Let's code
> You will find the full working example [on GitHub](https://github.com/GregOnNet/ng-consitant-component-style-api/blob/consistant-component-style-api-1/src/app/label.component.ts) here.
We start simple with a Component representing a Label.
By default, the label has a gray text. If needed, the text-color can be overridden.
> By the way, we use [TailwindCSS](https://tailwindcss.com/) to have a standardized way of applying CSS classes
Let's start by having a look at the usage.
You will see it is like working with standardized HTML-Elements.
```html
<!-- Component Template -->
<app-label>Default</app-label>
<app-label class="text-green-500">Green</app-label>
```
The _class_-Attribute is applied to the Component-Host-Element.
Next, we will dive into the implementation of the _LabelComponent_.
```ts
import { Component, computed, input } from '@angular/core';
import { twMerge } from 'tailwind-merge';
@Component({
selector: 'app-label',
standalone: true,
host: { '[class]': 'hostClass()' },
template: `<ng-content></ng-content>`
})
export class LabelComponent {
#classDefaults = 'p-2 text-slate-600';
class = input<string>('');
protected hostClass = computed(() => {
const classOverrides = this.class();
return twMerge(this.#classDefaults, classOverrides);
});
}
```
- In the _Component-Decorator_, we bind a [computed signal](https://angular.dev/guide/signals#computed-signal-dependencies-are-dynamic) to the class attribute.
- In the Component-Class, we add the _input()_ `class` to allow style overrides.
- The computed _hostClass()_ allows us to merge the `#classDefaults` with the `classOverrides`.
> In _JSX_ we achieve the same by writing `class={`p-2 ${...props.class}`}`.
The package [tailwind-merge](https://github.com/dcastil/tailwind-merge) helps us to combine the tailwind classes, safely. It will replace the defaults once an override is provided. For example, _text-slate-600_, will be removed as soon as _text-green-500_ has been provided.
## The simpler way
We found an open issue in the Angular repository that would simplify the whole styling process.
Eventually, we will get the possibility to manipulate the Component's host-Element in the template: [see \<ng-host>](https://github.com/angular/angular/issues/19119)
## Summary
We encountered difficulties customizing components to fit certain design requirements. We got inspired by different Frameworks:
- [Angular Material](https://material.angular.io/)
- [PrimeNg](https://primeng.org/)
- [QwikUI](https://qwikui.com/)
- [TaigaUI](https://taiga-ui.dev/)
- [SpartenUI](https://www.spartan.ng/).
> 🤝 We decided to provide a Style API that is as close as possible to existing Web-Standards. These are well known by web developers or can be easily communicated.
## 🙏🏻 Special Thanks
First, I want to thank you [Melory](https://www.linkedin.com/in/melory-ayala/) for going through all the discussions with me to find a good approach for our Component library. You know, I appreciate your input and our constructive & productive discussions.
I also thank all the community members for reviewing this article. I appreciated chatting with you all. Furthermore, I received valuable feedback from you.

GitHub, a premier platform for version control and collaboration, offers a powerful feature called webhooks. Webhooks enable communication between different applications by sending real-time data to external services when certain events occur on GitHub. This article explores the concept, setup, and use cases of [GitHub webhooks](https://keploy.io/blog/community/apis-vs-webhooks-make-a-github-webhook), shedding light on how they can enhance your development workflow.
**What are GitHub Webhooks?**
GitHub webhooks are automated messages sent from a GitHub repository to an external server when specific events happen within the repository. These events can range from code pushes and pull requests to issue comments and release updates. Webhooks facilitate the integration of GitHub with other services, automating workflows and improving efficiency.
**How GitHub Webhooks Work**
When an event occurs in a GitHub repository, a payload is sent to a configured URL (endpoint). This payload contains detailed information about the event, such as the branch, commit, author, and more. The receiving server can then process this data to perform actions like deploying code, sending notifications, or updating an issue tracker.
**Setting Up GitHub Webhooks**
Setting up webhooks in GitHub is a straightforward process. **Here’s a step-by-step guide:**
1. Create a Repository
First, create a repository on GitHub. If you already have a repository, navigate to its settings.
2. Navigate to Webhooks
In the repository settings, find the "Webhooks" section on the left sidebar. Click on "Add webhook."
3. Configure the Webhook
• Payload URL: Enter the URL of the server that will receive the webhook payload. This server should be set up to handle incoming HTTP POST requests.
• Content Type: Choose the format of the payload. Common options are application/json or application/x-www-form-urlencoded.
• Secret: (Optional) Add a secret token to verify the authenticity of the payload. This helps ensure that the payloads are coming from GitHub and not from malicious actors.
• Events: Select the events that will trigger the webhook. You can choose individual events or opt for “Send me everything” to receive payloads for all events.
4. Test the Webhook
GitHub allows you to test the webhook by sending a ping event. This is useful to ensure that your server is correctly receiving and processing the payloads.
**Handling Webhook Payloads**
Once the webhook is set up, your server needs to handle the incoming payloads. Here’s a basic example in Node.js using the Express framework:
```
javascript
Copy code
const express = require('express');
const bodyParser = require('body-parser');
const crypto = require('crypto');
const app = express();
const port = 3000;
app.use(bodyParser.json());
app.post('/webhook', (req, res) => {
const secret = 'your_secret';
const sig = req.headers['x-hub-signature'];
const payload = JSON.stringify(req.body);
const hmac = crypto.createHmac('sha1', secret);
const digest = `sha1=${hmac.update(payload).digest('hex')}`;
if (crypto.timingSafeEqual(Buffer.from(sig), Buffer.from(digest))) {
console.log('Received a valid payload:', req.body);
// Process the payload
} else {
console.log('Invalid signature');
}
res.status(200).end();
});
app.listen(port, () => {
console.log(`Webhook listener running on port ${port}`);
});
```
Common Use Cases for GitHub Webhooks
1. Continuous Integration/Continuous Deployment (CI/CD)
Webhooks can trigger CI/CD pipelines. For example, when code is pushed to the main branch, a webhook can notify a CI/CD server to build, test, and deploy the new code automatically.
2. Notifications and Alerts
Integrate GitHub with communication tools like Slack or Microsoft Teams to receive notifications about repository activities. This keeps the team informed about pull requests, issues, and deployments in real-time.
3. Automated Testing
Run automated tests whenever new code is pushed to the repository. Webhooks can trigger testing frameworks to ensure the new code does not break existing functionality.
4. Issue Tracking
Automatically update issue trackers like Jira or Trello based on GitHub activities. For example, closing an issue in GitHub can move the corresponding card in Trello to the "Done" column.
5. Custom Workflows
Webhooks can be used to create custom workflows tailored to specific needs. For example, updating documentation automatically when code changes are pushed or notifying stakeholders about specific events.
Security Considerations
While webhooks are powerful, they come with security considerations:
• Validate Payloads: Use the secret token to validate that incoming payloads are from GitHub. This prevents unauthorized sources from sending payloads to your server.
• Use HTTPS: Ensure that your webhook endpoint uses HTTPS to encrypt data in transit, protecting it from eavesdropping and tampering.
• Rate Limiting: Implement rate limiting on your server to protect against denial-of-service attacks.
• Logging: Keep logs of webhook events for monitoring and debugging purposes.
Best Practices
1. Modular Handlers: Design your webhook handlers to be modular. This allows you to add or modify functionalities without disrupting the entire system.
2. Error Handling: Implement robust error handling to deal with unexpected issues. Ensure your system can gracefully recover from failures.
3. Scalability: Plan for scalability. As your project grows, the frequency of webhook events may increase, requiring a scalable solution to handle the load.
4. Documentation: Document your webhook implementation and configuration for future reference and onboarding new team members.
**Conclusion**
GitHub webhooks are an invaluable tool for automating workflows and integrating GitHub with other services. By setting up webhooks, you can streamline processes, improve collaboration, and enhance productivity. Understanding how to configure, handle, and secure webhooks is essential for leveraging their full potential. Whether it's deploying code, running tests, or notifying teams, webhooks play a crucial role in modern software development practices.

1,879,048 | Odoo OWL Framework - extend and customize Component and Widget | Problem : When a user selects a product in the product field of the order line in a new sale order... | 0 | 2024-06-06T10:05:53 | https://dev.to/jeevanizm/odoo-owl-framework-extend-and-customize-component-and-widget-47jj | odoo, webdev | Problem : When a user selects a product in the product field of the order line in a new sale order form, the system should check if this product, associated with the same customer, already exists in any sale orders that are in the confirmed stage. If such a product is found, a popup warning with some action buttons should be displayed.
While one might consider using the onchange method in the Odoo backend to achieve this, the onchange API in Odoo does not support triggering popup wizards. Therefore, we need to use the OWL (Odoo Web Library) framework to perform this check and trigger the popup.
To implement this solution, we will extend the existing component, use RPC (Remote Procedure Call), and ORM (Object-Relational Mapping) API to access the database in the backend and pass the necessary values to the frontend.
Solution:
if you check in the product Field in sale order line you can see there is a widget - sol_product_many2one , so we need to extend this widget and add our custom logic
Identify the Existing Product Field:
Locate the existing product field in Odoo: odoo/addons/sale/static/src/js/sale_product_field.js.
Create a New JS File:
In your custom module, create a new JS file under custom_module/src/components.
Import the existing field as follows:
`/** @odoo-module */
import { registry } from "@web/core/registry";
import { many2OneField } from '@web/views/fields/many2one/many2one_field';
import { Component } from "@odoo/owl";
import { jsonrpc } from "@web/core/network/rpc_service";
import { _t } from "@web/core/l10n/translation";
import { useService } from "@web/core/utils/hooks";
import { Dialog } from "@web/core/dialog/dialog";
import { SaleOrderLineProductField } from '@sale/js/sale_product_field'`
important : do not forget to add - /** @odoo-module */ - on top of the file unless it will throw error
Create a Component:
Create a new component and extend from the existing product field.
```
// Define a class DuplicateProductDialog that extends the Component class
export class DuplicateProductDialog extends Component {
// Define the components used in this class, in this case, Dialog
static components = { Dialog };
// Define the properties (props) for the component
static props = {
close: Function, // Function to close the dialog
title: String, // Title of the dialog
orders: Array, // Array of orders to be displayed
onAddProduct: Function, // Function to handle adding a product
onRemoveProduct: Function // Function to handle removing a product
};
// Define the template for this component
static template = "custom_module.DuplicateProductDialog";
// Setup method to initialize the class
setup() {
// Set the title of the dialog from the props
this.title = this.props.title;
}
/**
* Public method to handle adding a product
* @public
* @param {number} orderId - The ID of the order to which the product will be added
*/
addProduct(orderId) {
// Call the onAddProduct function passed in the props
this.props.onAddProduct();
// Close the dialog
this.props.close();
}
/**
* Public method to handle removing a product
* @public
*/
removeProduct() {
// Call the onRemoveProduct function passed in the props
this.props.onRemoveProduct();
}
}
```
So we are going to replace the existing productField widget
```
// Define a class SaleOrderproductField that extends the SaleOrderLineProductField class
export class SaleOrderproductField extends SaleOrderLineProductField {
// Setup method to initialize the class
setup() {
// Call the setup method of the parent class
super.setup();
// Initialize the dialog service
this.dialog = useService("dialog");
}
// Asynchronous method to update the record with the provided value
async updateRecord(value) {
// Call the updateRecord method of the parent class
super.updateRecord(value);
// Check for duplicate products after updating the record
const is_duplicate = await this._onCheckproductUpdate(value);
}
// Asynchronous method to check for duplicate products in the sale order
async _onCheckproductUpdate(product) {
const partnerId = this.context.partner_id; // Get the partner ID from the context
const customerName = document.getElementsByName("partner_id")[0].querySelector(".o-autocomplete--input").value; // Get the customer name from the input field
const productId = product[0]; // Get the product ID from the product array
// Check if the customer name is not provided
if (!customerName) {
alert("Please Choose Customer"); // Alert the user to choose a customer
return true; // Return true indicating a duplicate product scenario
}
// Fetch sale order lines that match the given criteria
const saleOrderLines = await jsonrpc("/web/dataset/call_kw/sale.order.line/search_read", {
model: 'sale.order.line',
method: "search_read",
args: [
[
["order_partner_id", "=", partnerId],
["product_template_id", "=", productId],
["state", "=", "sale"]
]
],
kwargs: {
fields: ['id', 'product_uom_qty', 'order_id', 'move_ids', 'name', 'state'],
order: "name"
}
});
const reservedOrders = []; // Array to hold reserved orders
let stockMoves = []; // Array to hold stock moves
// Check if any sale order lines are found
if (saleOrderLines.length > 0) {
// Iterate through each sale order line
for (const line of saleOrderLines) {
// Fetch stock moves associated with the sale order line
const stockMoves = await jsonrpc("/web/dataset/call_kw/stock.move/search_read", {
model: 'stock.move',
method: "search_read",
args: [[
['sale_line_id', '=', line.id],
]],
kwargs: {
fields: ['name', 'state']
}
});
// Check if any stock moves are found
if (stockMoves.length > 0) {
// Add the order details to the reserved orders array
reservedOrders.push({
order_number: line['order_id'][1], // Order number
order_id: line['order_id'][0], // Order ID
product_info: line['name'], // Product information
product_qty: line['product_uom_qty'] // Product quantity
});
}
}
}
// Check if there are any reserved orders
if (reservedOrders.length > 0) {
// Show a dialog with duplicate product warning
this.dialog.add(DuplicateProductDialog, {
title: _t("Warning For %s", product[1]), // Warning title with product name
orders: reservedOrders, // List of reserved orders
onAddProduct: async (product) => {
return true; // Callback for adding product
},
onRemoveProduct: async (product) => {
const currentRow = document.getElementsByClassName('o_data_row o_selected_row o_row_draggable o_is_false')[0]; // Get the currently selected row
if (currentRow) {
currentRow.remove(); // Remove the current row
}
},
});
return true; // Return true indicating a duplicate product scenario
} else {
return false; // Return false indicating no duplicate products found
}
}
}
```
once we have this, we need to export this
```
SaleOrderproductField.template = "web.Many2OneField";
export const saleOrderproductField = {
...many2OneField,
component: SaleOrderproductField,
};
registry.category("fields").add("so_product_many2one", saleOrderproductField);
```
Integrate the New Widget:
Attach this new widget to the inherited sale order form as shown below:
<xpath expr="//field[@name='product_template_id']" position="attributes">
<attribute name="widget">so_product_many2one</attribute>
</xpath>
Create a Popup Wizard View:
Create a popup wizard view and define the required props (title and orders) inside the component to avoid errors in debug mode.
```
<?xml version="1.0" encoding="UTF-8"?>
<templates xml:space="preserve">
<t t-name="custom_module.DuplicateProductDialog">
<Dialog size="'md'" title="title" modalRef="modalRef">
<table class="table">
<thead>
</thead>
<tbody>
<t t-foreach="this.props.orders" t-as="item" t-key="item.order_id">
<div class="d-flex align-items-start flex-column mb-3">
<tr>
<td>
<p>
The product
<t t-out="item.product_info" />
is already reserved for this customer under order number
<span t-esc="item.order_number" />
with a quantity of
<strong>
<t t-out="item.product_qty" />
</strong>
. Please confirm if you still want to add this line item to the order
<button class="btn btn-primary me-1" t-on-click="() => this.addProduct(item.id)">
Add
</button>
<button class="btn btn-primary ms-1" t-on-click="() => this.removeProduct(item.id)">
Remove
</button>
</p>
</td>
</tr>
</div>
</t>
</tbody>
</table>
</Dialog>
</t>
</templates>
```
So we passed the props title, orders. Important to define these props inside Component
```
export class DuplicateProductDialog extends Component {
static components = { Dialog };
static props = {
close: Function,
title: String,
orders: Array,
onAddProduct: Function,
onRemoveProduct: Function,
};
```
otherwise, thise will throw an error as below on debug mode = 1 situation
OwlError: Invalid props for component ( https://www.odoo.com/forum/help-1/owlerror-invalid-props-for-component-taxgroupcomponent-currency-is-undefined-should-be-a-value-213238 )
So once we have everything, restart Odoo, upgrade module and try to create some Sale Orders with a particular customer with same product. The confirm one or two sale orders and try to create a new sale order for same customer and choose same product, then it should trigger a popup warning window.
OWL framework is a very important part of Odoo framework, but lack of proper documentation is a hurdle for Odoo developers, hope this could be a simple help.

1,879,045 | The Truth About Buying Spotify Followers: Effective Alternatives for Genuine Growth | In the dynamic world of digital music and podcasts, standing out on platforms like Spotify can be... | 0 | 2024-06-06T10:02:57 | https://dev.to/rajbhar445/the-truth-about-buying-spotify-followers-effective-alternatives-for-genuine-growth-3lm2 | In the dynamic world of digital music and podcasts, standing out on platforms like Spotify can be challenging. The allure of a large follower count is undeniable, as it can enhance your perceived popularity and potentially attract more listeners. However, **[buy spotify followers](https://dragcast.net/spotify/buy-spotify-followers/)** is the best strategy.
The Temptation of Buying Followers
For many artists and podcasters, the prospect of quickly increasing their follower count is tempting. More followers can create an impression of success, making your profile look more appealing. However, the drawbacks of purchasing followers far outweigh the temporary boost in numbers.
Drawbacks of Buying Spotify Followers
Engagement Quality: Purchased followers are usually fake accounts or bots. These accounts do not engage with your content, resulting in low interaction rates. Genuine engagement, such as likes, shares, and comments, is crucial for growing your presence on Spotify.
Algorithmic Impact: Spotify’s recommendation algorithms are designed to promote content that receives genuine engagement. Fake followers can distort your metrics, making it harder for the algorithm to recommend your music or podcasts to real listeners.
Reputation Concerns: Authenticity is key to building a loyal fanbase. If your followers discover that your numbers are artificially inflated, it can damage your credibility and relationship with your audience.
Effective Alternatives for Growing Your Spotify Followers
Instead of opting for quick fixes, consider these proven strategies for organic growth on Spotify:
Create High-Quality Content
Focus on producing top-notch music or podcasts that resonate with your target audience. High-quality content is the foundation of a loyal follower base.
Leverage Social Media
Promote your Spotify content on social media platforms. Engage with your audience, use relevant hashtags, and collaborate with influencers to reach a broader audience.
Collaborate with Other Creators
Collaborations can introduce your content to new listeners. Partner with other artists or podcasters to cross-promote each other’s work.
Submit to Playlists
Playlists are a powerful discovery tool on Spotify. Submit your tracks to popular playlists or create your own to attract more listeners.
Utilize Spotify for Artists
Use the tools and analytics provided by Spotify for Artists to understand your audience better. These insights can help you tailor your promotional strategies effectively.
Engage in Live Performances
Perform live, whether in-person or through live streaming platforms. Live performances help you connect with your audience and attract new followers.
Run Promotional Campaigns
Invest in promotional campaigns on social media or music platforms. Targeted ads can increase your visibility and draw more listeners to your Spotify profile.
Conclusion
While the idea of buying Spotify followers might seem like a quick way to boost your numbers, the long-term benefits of organic growth far surpass the short-lived advantages of artificial boosts.

1,879,044 | Mastering Route Groups in NextJS 14 | In the ever-evolving world of web development, organization and structure are key to building... | 0 | 2024-06-06T10:01:44 | https://dev.to/shawon/mastering-route-groups-in-nextjs-14-1oae | webdev, javascript, nextjs, programming | In the ever-evolving world of web development, organization and structure are key to building scalable and maintainable applications. With the release of NextJS 14, developers are introduced to a powerful feature called Route Groups, which offers a elegant solution for organizing routes and managing layouts within a NextJS project.
## What are Route Groups?
Route Groups are a convention in NextJS 14 that allows you to group related routes together without affecting the URL path structure. This feature is particularly useful when you need to organize routes by site section, intent, or team, while maintaining a clean and logical URL hierarchy.
## Creating Route Groups
To create a Route Group, you simply need to wrap the folder name with parentheses, like this: `(folderName)`. For example, you could have a route group called `(marketing)` or `(shop)`. Inside these folders, you can place your route files and nested layouts.
## Benefits of Route Groups
1. **Organized Routes**: Route Groups provide a way to keep related routes together, making it easier to navigate and maintain your codebase as your application grows.
2. **Nested Layouts**: With Route Groups, you can create multiple nested layouts within the same route segment level. This includes the ability to have multiple root layouts, each with its own `layout.js` file and HTML/body structure.
3. **Layout Segregation**: Route Groups allow you to opt specific routes into a shared layout by moving them into a dedicated group folder. Routes outside of this group will not share the same layout, providing greater flexibility in your application's UI and experience.
4. **Multiple Root Layouts**: By removing the top-level `layout.js` file and adding individual `layout.js` files within each Route Group, you can create multiple root layouts. This is particularly useful when partitioning your application into sections with completely different UIs or experiences.
## Practical Examples
1. **Organizing Routes without Affecting the URL Path**: Let's say you have a website with sections for marketing and an online shop. You can create Route Groups like `(marketing)` and `(shop)` to keep related routes together, while the URL paths remain unaffected.
2. **Opting Specific Segments into a Layout**: If you have routes like `account` and `cart` that should share a common layout, you can create a `(shop)` Route Group and move these routes inside. The `checkout` route, which doesn't share the same layout, can remain outside the group.
3. **Creating Multiple Root Layouts**: To create multiple root layouts, remove the top-level `layout.js` file and add individual `layout.js` files within each Route Group (e.g., `(marketing)` and `(shop)`). This allows you to define separate HTML and body structures for different sections of your application.
## Best Practices and Considerations
- Route naming within Route Groups has no special significance other than organization. It does not affect the URL path.
- Avoid resolving routes from different Route Groups to the same URL path, as this will cause an error.
- If using multiple root layouts, your home `page.js` file should be defined within one of the Route Groups (e.g., `app/(marketing)/page.js`).
- Navigating across multiple root layouts will trigger a full page load, as opposed to a client-side navigation.
By leveraging Route Groups in NextJS 14, you can achieve a higher level of organization and structure within your application, while maintaining clean URL paths and flexible layout management. Whether you're building a complex web application or a simple website, Route Groups provide a powerful tool to streamline your development process and enhance the maintainability of your codebase. | shawon |
1,877,087 | Not 💩, here's how to write actually good commit messages (hint: It's not just adding commit-lint) | Update build file Fixes dependency array Refactor Fix tests The most famous: Update README.md... | 0 | 2024-06-06T10:01:04 | https://dev.to/middleware/not-heres-how-to-write-actually-good-commit-messages-hint-its-not-just-adding-commit-lint-j2i | programming, git, codereview, productivity | - **Update build file**
- **Fixes dependency array**
- **Refactor**
- **Fix tests**
- _The most famous:_ **Update README.md** (Thanks Github 🤦)
These are... some spectacularly amazing commit messages that I've actually seen in the last month. 👀
And... some of these are in our codebases too.
A bit embarrassing. I know. 😅
But this is not okay 🙅, and ideally I would want to rid the world of these.
> ### "Sure, whatever. I don't think anything will change even after reading this blog."
For anything to change, I need to **convince** you that:
- This makes a real difference that YOU can feel or measure
- This makes a difference to someone else (which might be attributed to you later)
> ### "Okay, get on with it. What do I do, and what do I get from it?"
Well written commit messages have some obvious benefits:
### **1. 🧑💻 Easier debugging**
`git blame` makes it super easy to understand why a change was introduced, and makes it easier to ask the author relevant questions about it.
**`git blame`** isn't the first tool that's used during debugging, but for **complex issues** related to business logic, it's a **tool that comes into play** especially in medium to large sized companies. Some code simply evokes the question "Why was it written the way it was?" or "What purpose was this originally solving?". The answers to some questions don't lie in engineering, but in product decisions. And the author who wrote that has the best chance of knowing what decisions were involved.
Of course, `git blame` will tell you the author of a commit even without the need for fancy messages. So why is this part of this blog post?
Because how often do YOU as an author remember **what a commit that you write 6 months ago was doing**? Especially when it has a commit message like "Refactor"? **Tough luck right?**
I've seen more experienced devs write exceptionally helpful commit messages. I think some of them overdid it a little, but here's a rough example:
```
Fix crash on login screen due to null pointer exception.
- Checks for null values before accessing user profile data
- Adds unit test to cover this scenario
- Issue linked: BUG-5678
```
Maybe it's a bit too much, but damn if it isn't obvious AF.
Now when I need to debug an issue in this area, being able to `git blame` for the author and context can be a lifesaver.
_I say this with confidence because I used to be both on the giving and receiving side of this at Uber._
**This has a serious added benefit which you might overestimate as you read this blog:**
- Saves time for you and your team, and reduces frustration
**Debugging in the absence of context is PAIN.** It's not even the kind where you can say "What doesn't kill you, makes you stronger." Because it just frustrates you.
You know it. Your team knows it. And that's why you try to understand who introduced "that bug" anyway and talk to them, only to find out they left the company 2 years ago. Good luck. 🤝
With this, you're leaving behind a legacy that would **make people remember you fondly** and wish they could work with you again.
> **"What if I use merge or squash commits?"**
> _Some people have strong opinions for or against them._
> _All I'll say is, merge commits help to contain the context of a PR contained within a commit to a degree, but the individual commits themselves may not have much context associated with them if they are not well written._
> _And because a PR might involve a variety of dissimilar changes that work together to ship a feature, and the constituent changes might have their own context for being written that way, squashing them might effectively muddle all that context making it difficult to draw inference from the commit history._
> _**But perfectly functional software is written either way.** As long as you and your team agree that your way of merging PRs works for you with minimal issues, who I am I interfere?_
### **2. 🔍 Easier code reviews**
If your org doesn't care too much about making code reviews be painless and not make it feel like a chore, **you need to share this with your people**:
{% embed https://dev.to/middleware/the-senior-engineers-guide-to-the-code-reviews-1p3b %}
Now, how do better commit messages help with code reviews?
From [Middleware's](https://github.com/middlewarehq/middleware) analyzed data, an average PR in a mature codebase (active repo, past its setup phase) can be **around 300 lines**.
That's a lot of lines. And most of these changes are not happening in the same file. Neither should they. **300 lines is on the upper end of a file being readable** (it's not a rule set in stone though).
It's a near-guarantee that different kinds of changes are being shipped in these PRs that NEED to go together for the desired functionality to be shipped.
If you can't make a smaller PR for any reason, **you can make smaller commits** in the same PR. Make each commit contain the smallest piece of logically isolated change, such that the commit message can sufficiently explain what it contains. Because you don't want to write a commit message that's a paragraph long either, you'll need to create a commit that's small enough that roughly 50-60 characters can explain what it's about.
Now, the reviewer can **review your PR commit by commit** without having to follow up with you for everything or wondering why something was written the way it was (if they do, they'll have to ask you [the author], you know? Do you really have much time for that?).
### **3. 🚀 Better release notes!**
Or if you're not generating "release notes" exactly, then it's still **better documentation** of the history of your project!
Github, specifically, also allows you to **generate release notes** for your project automatically **from your commits**. And release notes are seen by a LOT of people to get an idea of what fixes or features new releases contain.
See the releases section of the [React codebase](https://github.com/facebook/react/releases), and see how many reactions each release note has!
Clearly **release notes matter to people**. And by writing well written commits, you're saving yourself effort from writing release notes.
And finally...
### **4. 👥 Encourages better practices across the team**
When team members see the benefits of well-written commit messages, they are likely to follow suit. This can lead to a more disciplined approach to code commits across the entire team, encouraging a culture of clarity and precision. This is the kind of stuff that makes an **SDE1 act think and act like an SDE2**.
{% embed https://dev.to/middleware/going-from-sde1-to-sde2-and-beyond-what-it-actually-takes-1cld %}
Here's another example of such a commit:
```
Update permissions routing layer to handle subroutes independently.
- TKT-1234
- The permissions routing logic was previously coupled with its nested routes
- This change will allow you to move subroutes to any other parent route without also having to make any changes to how the permissions for that subroute are defined
```
In environments where multiple people work on the same project, consistent and detailed commit messages can align everyone's understanding and expectations, **reducing potential conflicts** and misunderstandings, without needing as much time to block for context sharing.
And of course, if you can be the champion of better commit messages in your team or organization, you'd love to get the credits for any benefits that brings, won't you? 👀
**Teams that can work asynchronously, is a team that can work efficiently.** No one wants your teams to have bottlenecks on stuff like this. 👌
**UPDATE:**
I really should have covered this earlier, but if you're convinced about the idea of using good commit messages and are using it in some form regularly, you might be ready to take the next step.
The next step would be to have a standard way and structure of writing commits in your org. Adhering to standards can involve a bit of a friction in your experience, but it can prove to be fruitful in the long term.
Presenting, [Conventional Commits](https://conventionalcommits.org/)!
Thanks @taosif7 for reminding me of this!
{% embed https://github.com/conventional-commits/conventionalcommits.org %}
Conventional Commits is a specification for writing great commits in a standardised way. There are many tools which rely on commits written following this spec which may be able to automate even more things for you in terms of release notes, feature updates, separation of commits/PRs by the nature of the work involved in them (such as refactors, chores, fixes, features, etc.).
It's absolutely the next thing you should at least give a look.
## Wrapping this up
Good commit messages have serious GAINS. 💪
Gains for you, and the teams that you're a part of.
Less time spent debugging, fewer frustration moments, better documentation, automatic release notes, etc.
As a side-effect of all those improvements, you might even notice faster code deliveries, lesser wait time in reviews, fewer rework cycles!
Go on! Take credit for all the efficiency improvements you introduced!
_And see exactly how much of a gain it was for your teams by using a productivity intelligence tool, such as [Middleware](https://github.com/middlewarehq/middleware)!_ 🚀

1,879,039 | Maximizing ROI: From Google Analytics To Custom Analytics | Everyone is using Google Analytics; it is literally the first script everyone installs on their... | 0 | 2024-06-06T09:52:56 | https://sotergreco.com/maximizing-roi-from-google-analytics-to-custom-analytics | analytics, webdev | Everyone is using Google Analytics; it is literally the first script everyone installs on their website. If you run a SaaS business or an E-commerce store, you basically want to know everything about your audience.
Google Analytics plays a crucial role in understanding user behavior and your target audience. A study by [Surfshark](https://surfshark.com/global-ad-blocking), one of the biggest VPN providers across the globe, showed that over 37% of people use ad blockers.
This means that 37% of your visitors are not being tracked. We are going to analyze how I use custom analytics to achieve a 99% tracking rate while also maintaining privacy for my clients.
[https://surfshark.com/global-ad-blocking](https://surfshark.com/global-ad-blocking)
## Google Analytics Alternatives
Big Google Analytics competitors don't really do their job either. Large adblocker developer literally block all the competitors of google because there are the most common after Google.
Just by searching Google Analytics Competitors on Google you can find all the analytics providers that are most likely blocked by ad blockers.
![](https://cdn.hashnode.com/res/hashnode/image/upload/v1717658404637/238e8fe8-3e91-484f-ba5b-ad66da043600.png align="center")
## Smaller Providers
On my website, as you can see, I have installed both gtag, which is Google Analytics, and Vercel Analytics. Vercel Analytics is probably less known to the public but is still blocked by my AdBlocker.
Even in that case, we have a solution that we are going to talk about and how to get the most out of your analytics.
So don't believe that by choosing a smaller provider you are going to be safe. The likelihood of not tracking will be smaller but not zero.
## Risk displacement
The first thing you need to do is discuss with your developer about putting multiple analytics on your website. Risk displacement is a business term that can be applied anywhere in life.
Just like you don't keep all of your money in one bank account, you should do the same with your data.
I am using three different analytics. One of them provides specific user events. Google doesn't really do anything; I might delete it after finishing this article because it literally doesn't track half of the traffic.
Below are the same analytics for the past 30 days. As you can see, Google Analytics doesn't track almost anything. Even the Average Engagement Time is wrong.
## Github Opensource
I am not going to discuss exactly which analytics I am using because I don't want them to start getting blocked as well. But you can ask your developer to search on GitHub for open-source analytics solutions. The one I am using can be found easily, and if [UBlock Origin](https://chromewebstore.google.com/detail/ublock-origin/cjpalhdlnbpafiamejdnhcphjbkeiagm?hl=en&pli=1) doesn't catch it, it means that no other ad blocker will.
Always use [UBlock Origin](https://chromewebstore.google.com/detail/ublock-origin/cjpalhdlnbpafiamejdnhcphjbkeiagm?hl=en&pli=1) on your website to check if it block the analytics or not. Basically UBlock Origin is one of the best Ad Blockers in the market right now.
Just click on the logger and check what scripts it highlights with red. Even if you don't are a developer you can check it very easily.
## Domain Masking
Domain masking is covering the domain of the tracking script with a reverse proxy server. This is quite complex, and if you are not a developer, you might have to hire someone to do it for you.
You need to keep in mind that domain masking is not always possible and might not work for some scripts.
Also, I want to quickly mention Shopify because the analytics of the platform are both server-side and client-side. Ad blockers do not work, and Shopify tracks everything. So, congrats to the Shopify team for that.
## **Privacy**
Privacy is not something Google cares about. The alternatives I found were not only accurate but also privacy-friendly. The data didn't link to any other social profiles and was stored in my database.
You can get to know your audience in secure ways. If you care about them, you want the best for them. The open-source alternatives you can find not only don't store the data on Google Server but you store the data and you don't link them to any other social profiles.
## Conclusion
In conclusion, while Google Analytics is a popular tool for tracking website metrics, it falls short in capturing data from users who employ ad blockers.
By exploring custom analytics solutions, businesses can achieve higher tracking accuracy and maintain user privacy. Employing multiple analytics providers, leveraging open-source solutions, and using techniques like domain masking can significantly enhance tracking effectiveness.

1,879,033 | Feature testing with PHPUnit and things to avoid | I’ve had the opportunity to see many feature tests in PhpUnit that lack the fundamentals of a proper... | 0 | 2024-06-06T09:45:33 | https://dev.to/massivebrains/feature-testing-with-phpunit-and-things-to-avoid-58ao | I’ve had the opportunity to see many feature tests in PhpUnit that lack the fundamentals of a proper Unit test. We will discuss how to write tests properly and ensure that our tests are valuable. Before we begin, if you are unfamiliar with PHPUnit or Testing as a concept no worries, I’ll give a brief background.
In today’s changing world, where we have embraced a continuous delivery and integration of our services and products, they often change frequently. Whether changed by the original author/maintainer, or by someone else. It is therefore imperative that we have some kind of safety, some tests that ensure that the behaviour of the service remains the same except intentionally modified.
But there are different types of tests, Unit Tests, Feature Tests, Integration Tests, Performance Tests and so on. In this post, I want to focus on how we should write Feature tests the right way.
Feature tests are types of tests that validate different variations of a feature. Feature tests ensure that users see and experience what you want them to experience. I believe feature tests can also qualify as integration tests.
### Always make sure your tests are independent of each other
let's take a scenario, where a user will call a simple get endpoint that would be handled by a service. Take a look at the test below:
```php
class OrderServiceTest extends TestCase
{
private $user = null;
private $service = null;
public static function setupBeforeClass(): void
{
$this->user = User::factory()->create([
'permissions' => []
]);
$this->service = new OrderService($this->user);
}
public function test_get_order_service_throws_when_user_does_not_have_access()
{
$this->expectException(UnauthorizedException::class);
$this->service->get();
}
}
```
As you can see, in the `setupBeforeClass( )` we are instatiating the service which depends on the `$user`.
When you have just 1 test in this file, this is fine, however, this becomes a bad idea when you have multiple tests. The given test does not control the instatiation of the service. Therefore it is possible for other tests to modify the `$this->user` or `$this->service` while this test is running.
Also, this test does not paint the full picture of an actual user journey when they try to call the order get endpoint. So to decouple the test we can have something like this:
```php
public function test_get_order_service_throws_when_user_does_not_have_access()
{
$user = User::factory()->create([
'permissions' => []
]);
$service = new OrderService($this->user);
$this->expectException(UnauthorizedException::class);
$service->get();
}
```
As you can see, the test now has the complete setup of what it needs before its assertions. This test does not depend on anything else and is easy to understand what needs to exist before this exception can be thrown.
Note that this does not mean that using `setupBeforeClass( )` is bad, we can always setup things that the entire tests generally need and is guaranteed to be needed in exactly the same way like an instance of a mock.
### Do not test too many things at once
When we have a complex feature that does a number of things. We can easily write 1 test that handles many assertions, this makes it feel like that singular test will cover all the scenarios. - Don’t do this.
Having atomic tests that focus on a single flow with a couple of assertions is more valuable and easier to understand by others.
Typically, the easiest way to divide a huge feature/method to multiple independent tests is to think about all the code paths, if statements, exceptions, and external service calls and try to test them in each test.
Note that the combination of all these tests eventually still gives you a full feature test.
### Only Mock 3rd Party services
Mocking is a process used in testing when the feature being tested has external dependencies. The purpose of mocking is to isolate and focus on the code being tested and not on the behaviour or state of external dependencies.
We should only be mocking 3rd party services in our tests, 3rd party services are external systems like APIs or SDKs that are been used in the test. These tools are what we do not have control over, hence needs mocking.
Avoid mocking the Database, other methods in the application and so on. This is important because again, we are writing a feature test and not a unit test.
### Avoid Huge test files
I know this may be subjective, but it is actually good for our future selves. Imagine having a failing feature test and having to look for the test in a 4K lines of code and wondering if the test is failing because of some flaky test above or below it.
If you have a major feature you can create a folder just for that feature and have different test files which would have similar test scenarios in them and are grouped together. This way - when such a scenario needs to change, it would be very clear which test needs to be included, modified or deleted in context.
### Avoid tests using other features to Setup
Tests typically follow the `GIVEN-WHEN-THEN` approach. It is always easy to see the context given to a test in the first few lines (typically considered setup) for that test.
Setup should be as basic and direct as possible. Do not use other service methods to do a setup, just because the internal implementation for that service is doing the same expected setup that is needed.
The obvious reason for this is still related ot independence, your test should be as independent as possible without been at risk of failing just because a completely unrelated feature was modified. If you have to insert records to the database to set some context, do not use a register( ) method for example even though it does the same insert as you expect. You should always cary out all the setup manually without calling existing methods.
### Avoid Logic / Code Complexities in your assertions
When you have to do assertions that may be alot, lets say asserting that an array in a particular order, it is always a good idea to do this manually. Take a look at the set of assertions below:
```php
$this->assertEquals('One', $reponse[0]);
$this->assertEquals('Two', $reponse[1]);
$this->assertEquals('Three', $reponse[2]);
```
It is very easy to see things like this and say, Oh, I can just do a `foreach( )` and have 1 `$this->assertEquals( )` . Avoid that. This is because you don’t want your test carrying unnecessary logic when it should just focus on behaving as the user and as close to that as possible.
Tests have to be clear, it needs to be as clean, simple and straightforward as possible.
### Do not expose private properties as public just because of the tests
When a class has private properties and you do like to validate their state in a give test, avoid setting them as public. Create a getter instead.
Infact, often times, these kind of properties can be implicity tested, for example, if the value of such property is eventually going to be written to the database, then you can check the database.
When the feature itself is been highly modified just because of the tests, you should already know that something is not right.
In conclusion, feature tests should always focus on ensuring that the feature is used right, it should be as simple, independent and straightforward as possible.

1,879,032 | OBJECT-RELATIONAL MAPPING in PYTHON | KEY VOCAB Object-Relational Mapping(ORM): A technique used to convert database records into objects... | 0 | 2024-06-06T09:43:57 | https://dev.to/victor_wangari_6e6143475e/object-relational-mapping-in-python-42pg | **KEY VOCAB**
Object-Relational Mapping(ORM): A technique used to convert database records into objects in an object-oriented language.
**INTRODUCTION**
**Object Relational Mapping is way for our python programs to manage database data by "mapping" database tables to classes and instances of classes to rows in those tables.
**There is no special programming magic to an ORM — it is simply a manner in which we implement the code that connects our Python program to our database. For example, you can use code like this to connect your Python program to a given database:
**db_connection = sqlite3.connect('db/my_database.db')
db_cursor = db_connection.cursor()
**
An ORM is really just a concept. It is a design pattern , a conventional way for us to organize our program when we want those programs to connect to a database.The conventional is this :
When "mapping" our program to a database, we equate classes with database tables, and instances of those classes with table rows.
**WHY USE ORM??**
.Cutting down repetitive code.
.Implementing conventional patterns that are organized and sensical
**Cutting Down on Repetition**
**As programmers , you might remember we are lazy.We don't like to repeat ourselves if we can avoid it. Repetition qualifies as a "code smell". Instead of repeating the same, or similar, code any time we want to perform common actions against our database, we can write a series of methods to abstract that behavior.
** We can use **save()** method on our classes that handles the common actions if **INSERT**ing data into database.
**LOGICAL DESIGN**
**Another important reason to implement the ORM pattern is that it just makes sense. Telling our Python program to communicate with our database is confusing enough without each individual developer having to make their own, individual decision about how our program should talk to our database.
Instead, we follow the convention: classes are mapped to or equated with tables and instances of a class are equated to table rows.
If we have a Cat class, we have a cats table. Cat instances get stored as rows in the cats table.
Further, we don't have to make our own potentially confusing or non-sensical decision about what kinds of methods we will build to help our classes communicate with our database. Just like the save() method we previewed above, we will learn to build a series of common, conventional methods that our programs can rely on again and again to communicate with our database.

## type
"BiquadFilterNode" has preset filters. I can use them by "BiquadFilterNode.type".
* allpass
* bandpass
* highpass
* highshelf
* lowpass
* lowshelf
* notch
* peaking
* [BiquadFilterNode - Web APIs | MDN](https://developer.mozilla.org/en-US/docs/Web/API/BiquadFilterNode)
* [Web Audio API](https://webaudio.github.io/web-audio-api/#BiquadFilterNode)
## Modify filters
I can modify the selected filter by "gain", "frequency", "detune", "Q".
### gain
I can control gain of filter by "BiquadFilterNode.gain".
Only "highshelf", "lowshelf", "peaking" of "BiquadFilterNode.type" can use.
The lowest value is -40(dB) and the highest one is 40(dB).
* [BiquadFilterNode.gain - Web APIs | MDN](https://developer.mozilla.org/en-US/docs/Web/API/BiquadFilterNode/gain)
### frequency, detune
"frequency", "detune" are used to compute frequency of the filter.
```
computedFrequency(t) = frequency(t) * pow(2, detune(t) / 1200)
```
* [Web Audio API #BiquadFilterNode](https://webaudio.github.io/web-audio-api/#BiquadFilterNode)
* [BiquadFilterNode.frequency - Web APIs | MDN](https://developer.mozilla.org/en-US/docs/Web/API/BiquadFilterNode/frequency)
* [BiquadFilterNode.detune - Web APIs | MDN](https://developer.mozilla.org/en-US/docs/Web/API/BiquadFilterNode/detune)
Because some types emphasize specific frequency by default, I can't hear the sound when I set specific values into them.
|type|the value what I can't hear the sound|
|-|-|
|bandpass|10|
|highpass|22050|
|lowpass|10|
I can't feel the differences when I change the values with "highshelf", "lowshelf", "peaking".
### Q
This express Quality factor.
I haven't understood what is Quality factor.
So maybe I will wrtite more about it later.
The max value and min value are different per types.
For example, when I use "bandpass" and set Q value as 100, I can't hear the sound.
When I use "highpass" and set Q value as 100, I hear some noize like howling.

Microservice architectures often use internal APIs for communication between microservices, and many software products provide external APIs to users. As these applications evolve, existing API behaviors constantly change, and new APIs are introduced.
In addition, individual API behaviors also become complicated as applications seek to expose larger functionalities through APIs. Over time, it becomes increasingly challenging to keep track of all the application APIs along with their expected behavior under different scenarios. API flow diagrams address this challenge by visually representing the interactions among the different internal components of the system affected by a given API. They help with clearly defining and communicating the expected behavior of an API in various levels of detail.
##Why API flow diagrams are needed
API flow diagrams are a visual representation of the expected behavior of the API in different scenarios. This behavior is shown through the interactions among different internal components of the system that the API uses over the course of its execution.
API flow diagrams seek to address various challenges that API development teams face over the lifecycle of an API. When utilized properly, they ease communication and collaboration and help ensure consistent API behavior over time.
As an example, consider an API server for a bank. The development team is in the process of designing an API to create customer bank accounts. Customers would interact with this API via a web or mobile application, and over the course of the API's execution, it would need to call a number of services.
It would first need to check if a user already exists in the system and has the privileges to create an account. It could then make a number of checks about the user, such as whether the user already had the same kind of account, had the required credit score to open it, had any known criminal cases pending, etc. Each of these validations would require checks in different parts of the banking system and would result in internal API calls to different services.
The API would also be expected to behave differently based on the results of these subsequent API calls. Thus, the API’s expected behavior encompasses a large set of possible behaviors based on different external factors.
It is important to define this expectation clearly and communicate it to all stakeholders involved in creating and maintaining the API. If the development team is unable to visualize the entire behavior of the API, it is highly probable that changes to intermediate systems would be incompatible with the overall API behavior and cause it to change or break.
##Use cases for API flow diagrams
Effective API flow diagrams document the complex behavior of an API in a concise and readable way. The internal components of the applications involved in the API’s execution are abstracted as actors in the system or as labeled symbols so that the reader can focus on the overall flow of the API.
API flow diagrams provide benefits within a given team because new members can study them during onboarding, which helps new developers more quickly gain an understanding of the overall system and how their individual changes and contributions to the codebase could affect other components and teams.
Across teams, API flow diagrams enable easier collaboration and communication. It is much simpler for a software architect to explain to a development team how the subsystem they are building is expected to behave when the developers involved have an API flow diagram to study.
These diagrams also serve as documentation, providing a precise description of the API’s behavior against which its implementation can be tested to ensure correctness. They remain a source of truth for the future, ensuring that code or configuration changes do not introduce problematic changes or cause unexpected behavior. If they do, well-crafted diagrams aid in identifying and fixing these issues earlier and more quickly.
In our bank example, it would be much simpler to identify which APIs need to be tested when the credit score system is changed if the right API flow diagrams are in place. Any disagreements between teams about the API’s expected behavior can be resolved by referring to the diagram.
##Types of API flow diagrams
A variety of different types of diagrams have evolved over time to show API behavior. In this article, we will focus on two diagram types that can be used to represent three distinct aspects of an API as it interacts with a system: system diagrams and sequence diagrams.
###System diagram
A system diagram provides a high-level overview of a system. All the components that make up internal subsystems are shown using a single architectural block in the diagram, allowing developers to focus on the high-level flow of communication between components.
Using a high-level representation like this can help document an API’s general structure without getting too deep into the details of each component’s internal behavior. System diagrams can be used to get an initial, introductory understanding of how the API is expected to behave and which components of the system will be involved in various transactions.
This can help you identify which developers or teams will be needed to build features and get a sense of the internal interfaces required.
###Sequence diagram
Sequence diagrams represent the different components of the system or API as the origins of vertical “lanes” in a timeline. The API execution begins at the start of this timeline, and the flow of requests and data over its lifetime is indicated by horizontal arrows across the lanes. This allows you to focus only on the components of the system that are involved in the API’s execution, potentially at a more granular level than is achievable using a system diagram.
##Conclusion
API flow diagrams play an important role in effectively designing, building, and maintaining complex software systems and APIs.
When used correctly, they aid developer understanding, ease collaboration between teams, simplify onboarding, and serve as documentation.
As applications continue to grow in complexity, rather than treating these diagrams as secondary documentation artifacts, keeping them as integral parts of the development workflow will become increasingly critical.
With the right discipline around creation and maintenance, API flow diagrams can evolve from being supplementary materials to becoming indispensable tools that are tightly integrated into modern application development.
##What’s next
This is just a brief overview and it doesn't include many important aspects of API flow diagrams such as:
- Example of a network/environment diagram
- Best practices to avoid rendering these diagrams ineffective or even counterproductive
- AI and the future of API flow diagrams

1,879,026 | Understanding Where Deleted Files Go After Deleting them from Recycle Bin and How to Recover Them | A friend asked me as a developer where do deleted files go to after been deleted from the Recycle... | 0 | 2024-06-06T09:37:58 | https://dev.to/e-tech/understanding-where-deleted-files-go-after-deleting-them-from-recycle-bin-and-how-to-recover-them-2aej | filesystem, webdev | A friend asked me as a developer where do deleted files go to after been deleted from the Recycle Bin?
At first, i couldn't give an answer because i didn't know how or where it went. I had to do some research to find out.
When files are deleted from your computer, they often go through a two-step process: they first move to the Recycle Bin, and then, upon deletion from the Recycle Bin, they enter a more complex state. Understanding this process can help you comprehend how data recovery tools work and how to avoid data loss. This article will delve into the journey of deleted files, outline various tools for recovering these files, and provide steps to prevent data loss.
What Happens When Files Are Deleted?
1. Initial Deletion: The Recycle Bin
When you first delete a file, it doesn't immediately disappear from your hard drive. Instead, it moves to the Recycle Bin (or Trash on macOS). This system folder temporarily holds deleted files, allowing easy recovery if you realize the deletion was a mistake.
2. Permanent Deletion: Beyond the Recycle Bin
When a file is deleted from the Recycle Bin, it is not actually erased from your hard drive. **Instead, the space occupied by the file is marked as available for new data**. Until new data overwrites this space, the original file remains recoverable. The file's pointers in the file system are removed, making it inaccessible through normal means.
3. Data Overwriting
If new data is written to the space previously occupied by the deleted file, the file becomes partially or entirely unrecoverable. This is why the timing of data recovery attempts is crucial.
**Tools for Recovering Deleted Files**
Several tools can help recover files deleted from the Recycle Bin. These tools work by scanning the hard drive for remnants of deleted files and attempting to reconstruct them. Here are some popular options:
1. Recuva
Recuva, developed by Piriform, is a user-friendly tool that can recover files from hard drives, memory cards, and other storage devices. It offers a deep scan mode for more thorough searches and can also securely delete files you want to erase permanently.
2. EaseUS Data Recovery Wizard
EaseUS Data Recovery Wizard is a comprehensive tool that supports recovery from various storage media. It offers a simple interface, making it accessible for users with minimal technical expertise. It also supports recovery from formatted drives and lost partitions.
3. Disk Drill
Disk Drill is known for its advanced scanning algorithms and support for a wide range of file systems, including NTFS, FAT32, and exFAT. It also includes features like data protection and drive backup.
4. Stellar Data Recovery
Stellar Data Recovery is a robust tool designed for both personal and professional use. It can recover files from damaged or corrupted drives and offers a preview of recoverable files before proceeding with the recovery process.
5. PhotoRec
PhotoRec is an open-source tool designed to recover lost files, including documents, archives, and media files, from hard disks, CD-ROMs, and digital cameras. It ignores the file system, which means it can work even if your media's file system is severely damaged or reformatted.
**Steps to Avoid Data Loss**
Preventing data loss is as important as knowing how to recover lost data. Here are some steps to help you protect your valuable files:
1. Regular Backups
Local Backups: Use external hard drives or USB drives to create regular backups of important files.
Cloud Backups: Utilize cloud services like Google Drive, Dropbox, or OneDrive for off-site backups that are accessible from anywhere.
2. Use Reliable Antivirus Software
Ensure your system is protected from malware and viruses that can corrupt or delete your data. Regularly update your antivirus software to protect against new threats.
3. Implement Data Redundancy
Store copies of your data in multiple locations. This can include using RAID configurations on your hard drives or maintaining physical copies of critical documents.
4. Avoid Physical Damage
Protect your devices from physical harm. Use protective cases, avoid exposure to extreme temperatures, and handle your devices with care.
5. Regular Maintenance
Perform regular maintenance on your hard drives to check for and fix errors. Tools like CHKDSK on Windows can help maintain the integrity of your storage media.
6. Be Cautious with File Deletion
Double-check before deleting files, and use the Recycle Bin or a similar feature as a safety net. Avoid using "Shift + Delete" for immediate permanent deletion unless you are certain.
I hope with this little piece you have come to understand where your deleted files goes to and how you can prevent data loss. | e-tech |

7. JSX Best Practices
### 1. Introduction to JSX
JSX looks like HTML but is transformed into JavaScript before being rendered in the browser. It allows developers to write UI elements in a syntax that resembles HTML, making the code easier to understand and maintain.
```jsx
const element = <h1>Hello, world!</h1>;
```
### 2. Embedding Expressions in JSX
You can embed JavaScript expressions within JSX using curly braces `{}`.
```jsx
const name = 'John';
const element = <h1>Hello, {name}!</h1>;
```
👉 **[Download eBook](https://qirolab.gumroad.com/l/javascript-from-es2015-to-es2023)**
[](https://qirolab.gumroad.com/l/javascript-from-es2015-to-es2023)
### 3. JSX Syntax Rules
JSX has some important syntax rules:
- **Single Parent Element**: JSX expressions must have one parent element.
- **Closing Tags**: All tags must be closed.
- **CamelCase for Attributes**: HTML attributes are written in camelCase.
```jsx
const element = (
<div>
<h1>Hello, world!</h1>
</div>
);
```
### 4. Styling in JSX
In JSX, styles are written as objects, and CSS properties are written in camelCase.
```jsx
const divStyle = {
color: 'blue',
backgroundColor: 'lightgray'
};
const element = <div style={divStyle}>Styled text</div>;
```
### 5. Conditional Rendering in JSX
You can conditionally render elements using JavaScript operators like `if` statements and ternary operators.
```jsx
const isLoggedIn = true;
const element = isLoggedIn ? <h1>Welcome back!</h1> : <h1>Please sign in.</h1>;
```
### 6. Lists and Keys in JSX
When rendering lists of elements, each element should have a unique `key` attribute to help React identify which items have changed.
```jsx
const numbers = [1, 2, 3, 4, 5];
const listItems = numbers.map((number) =>
<li key={number.toString()}>{number}</li>
);
const element = <ul>{listItems}</ul>;
```
### 7. JSX Best Practices
- **Keep JSX readable**: Break down complex components into smaller, reusable components.
- **Use fragments**: Use React fragments (`<React.Fragment>` or `<>`) to group multiple elements without adding extra nodes to the DOM.
- **Self-closing tags**: Use self-closing tags for elements without children.
- **Consistent style**: Stick to a consistent style for writing JSX.
```jsx
const element = (

1,873,927 | Core Architectural Components of Azure. | Microsoft Azure relies on a few key architectural components to provide redundancy and high... | 0 | 2024-06-06T09:25:58 | https://dev.to/laoluafolami/core-architectural-components-of-azure-734 | Microsoft Azure relies on a few key architectural components to provide redundancy and high availability. The core Azure architectural components include:
1. Azure regions, region pairs, and sovereign regions.
2. Availability Zones.
3. Azure Resources and Resource Groups.
4. Subscriptions.
5. Management groups.
## Azure Regions
A region is a geographical area on the planet that contains at least one, but potentially multiple data centers that are nearby and networked together with a low-latency network. Azure intelligently assigns and controls the resources within each region to ensure workloads are appropriately balanced.
When you deploy a resource in Azure, you'll often need to choose the region where you want your resource deployed.
The Azure region is a set of data centers that are deployed within a latency-defined perimeter, and connected via an underlying dedicated regional low-latency network.
With more than 60 Regions, comprising 160+ data centres in 140 countries, Azure is one of the largest cloud platforms with more locations offered than any other providers.
**Region pairs**
Most Azure regions are paired with another region within the same geography (such as US, Europe, or Asia) at least 300 miles away. This approach allows for the replication of resources across a geography that helps reduce the likelihood of interruptions because of events such as natural disasters, civil unrest, power outages, or physical network outages that affect an entire region. For example, if a region in a pair was affected by a natural disaster, services would automatically fail over to the other region in its region pair.
Examples of region pairs in Azure are West US paired with East US and South-East Asia paired with East Asia. Because the pair of regions are directly connected and far enough apart to be isolated from regional disasters, you can use them to provide reliable services and data redundancy.
**Additional advantages of region pairs:**
-
If an extensive Azure outage occurs, one region out of every pair is prioritized to make sure at least one is restored as quickly as possible for applications hosted in that region pair.
-
Planned Azure updates are rolled out to paired regions one region at a time to minimize downtime and risk of application outage.
-
Data continues to reside within the same geography as its pair (except for Brazil South) for tax- and law-enforcement jurisdiction purposes.
**Sovereign Regions**
In addition to regular regions, Azure also has sovereign regions. Sovereign regions are instances of Azure that are isolated from the main instance of Azure. You may need to use a sovereign region for compliance or legal purposes.
Azure sovereign regions include:
-
US DoD Central, US Gov Virginia, US Gov Iowa and more: These regions are physical and logical network-isolated instances of Azure for U.S. government agencies and partners. These datacenters are operated by screened U.S. personnel and include additional compliance certifications.
-
China East, China North, and more: These regions are available through a unique partnership between Microsoft and 21Vianet, whereby Microsoft doesn't directly maintain the datacenters.
## Availability Zones.
Availability zones are physically separate datacenters within an Azure region. Each availability zone is made up of one or more datacenters equipped with independent power, cooling, and networking. An availability zone is set up to be an isolation boundary. If one zone goes down, the other continues working. Availability zones are connected through high-speed, private fiber-optic networks.
**Use availability zones in your apps**
You want to ensure your services and data are redundant so you can protect your information in case of failure. When you host your infrastructure, setting up your own redundancy requires that you create duplicate hardware environments. Azure can help make your app highly available through availability zones.
You can use availability zones to run mission-critical applications and build high-availability into your application architecture by co-locating your compute, storage, networking, and data resources within an availability zone and replicating in other availability zones. Keep in mind that there could be a cost to duplicating your services and transferring data between availability zones.
Availability zones are primarily for VMs, managed disks, load balancers, and SQL databases. Azure services that support availability zones fall into three categories:
-
Zonal services: You pin the resource to a specific zone (for example, VMs, managed disks, IP addresses).
Zone-redundant services: The platform replicates automatically across zones (for example, zone-redundant storage, SQL Database).
-
Non-regional services: Services are always available from Azure geographies and are resilient to zone-wide outages as well as region-wide outages.
Even with the additional resiliency that availability zones provide, it’s possible that an event could be so large that it impacts multiple availability zones in a single region. To provide even further resilience, Azure has Region Pairs.
## Azure resources and resource groups
A resource is the basic building block of Azure. Anything you create, provision, deploy, etc. is a resource. Virtual Machines (VMs), virtual networks, databases, cognitive services, etc. are all considered resources within Azure.
Resource groups are simply groupings of resources. When you create a resource, you’re required to place it into a resource group. While a resource group can contain many resources, a single resource can only be in one resource group at a time. Some resources may be moved between resource groups, but when you move a resource to a new group, it will no longer be associated with the former group. Additionally, resource groups can't be nested, meaning you can’t put resource group B inside of resource group A.
Resource groups provide a convenient way to group resources together. When you apply an action to a resource group, that action will apply to all the resources within the resource group. If you delete a resource group, all the resources will be deleted. If you grant or deny access to a resource group, you’ve granted or denied access to all the resources within the resource group.
When you’re provisioning resources, it’s good to think about the resource group structure that best suits your needs.
For example, if you’re setting up a temporary dev environment, grouping all the resources together means you can deprovision all of the associated resources at once by deleting the resource group. If you’re provisioning compute resources that will need three different access schemas, it may be best to group resources based on the access schema, and then assign access at the resource group level.
There aren’t hard rules about how you use resource groups, so consider how to set up your resource groups to maximize their usefulness for you.
## Azure subscriptions
In Azure, subscriptions are a unit of management, billing, and scale. Similar to how resource groups are a way to logically organize resources, subscriptions allow you to logically organize your resource groups and facilitate billing.
Using Azure requires an Azure subscription. A subscription provides you with authenticated and authorized access to Azure products and services. It also allows you to provision resources. An Azure subscription links to an Azure account, which is an identity in Microsoft Entra ID or in a directory that Microsoft Entra ID trusts.
An account can have multiple subscriptions, but it’s only required to have one. In a multi-subscription account, you can use the subscriptions to configure different billing models and apply different access-management policies. You can use Azure subscriptions to define boundaries around Azure products, services, and resources. There are two types of subscription boundaries that you can use:
-
Billing boundary: This subscription type determines how an Azure account is billed for using Azure. You can create multiple subscriptions for different types of billing requirements. Azure generates separate billing reports and invoices for each subscription so that you can organize and manage costs.
-
Access control boundary: Azure applies access-management policies at the subscription level, and you can create separate subscriptions to reflect different organizational structures. An example is that within a business, you have different departments to which you apply distinct Azure subscription policies. This billing model allows you to manage and control access to the resources that users provision with specific subscriptions.
## Azure management groups.
The final piece is the management group. Resources are gathered into resource groups, and resource groups are gathered into subscriptions. If you’re just starting in Azure that might seem like enough hierarchy to keep things organized. But imagine if you’re dealing with multiple applications, multiple development teams, in multiple geographies.
If you have many subscriptions, you might need a way to efficiently manage access, policies, and compliance for those subscriptions. Azure management groups provide a level of scope above subscriptions. You organize subscriptions into containers called management groups and apply governance conditions to the management groups. All subscriptions within a management group automatically inherit the conditions applied to the management group, the same way that resource groups inherit settings from subscriptions and resources inherit from resource groups. Management groups give you enterprise-grade management at a large scale, no matter what type of subscriptions you might have. Management groups can be nested.
**Management group, subscriptions, and resource group hierarchy.**
You can build a flexible structure of management groups and subscriptions to organize your resources into a hierarchy for unified policy and access management. The following diagram shows an example of creating a hierarchy for governance by using management groups.
Some examples of how you could use management groups might be:
-
Create a hierarchy that applies a policy. You could limit VM locations to the US West Region in a group called Production. This policy will inherit onto all the subscriptions that are descendants of that management group and will apply to all VMs under those subscriptions. This security policy can't be altered by the resource or subscription owner, which allows for improved governance.
-
Provide user access to multiple subscriptions. By moving multiple subscriptions under a management group, you can create one Azure role-based access control (Azure RBAC) assignment on the management group. Assigning Azure RBAC at the management group level means that all sub-management groups, subscriptions, resource groups, and resources underneath that management group would also inherit those permissions. One assignment on the management group can enable users to have access to everything they need instead of scripting Azure RBAC over different subscriptions.
Important facts about management groups:
-
10,000 management groups can be supported in a single directory.
A management group tree can support up to six levels of depth. This limit doesn't include the root level or the subscription level.
-
Each management group and subscription can support only one parent.

1,879,016 | How to Check if a String Contains Another String in C# 🔍 | Overview of C# String Manipulation Dive into the world of string manipulation with C#! You... | 0 | 2024-06-06T09:23:00 | https://dev.to/bytehide/how-to-check-if-a-string-contains-another-string-in-c-3034 | string, csharp, programming, tutorial | ## Overview of C# String Manipulation
Dive into the world of string manipulation with C#! You might be asking yourself, “why should I be interested in string manipulation?” Hopefully, this section will give you the answers.
### The Importance of String Manipulation in Coding
Without a good understanding of string manipulation; it’s hard to get the most of C#. It’s like trying to paint a masterpiece without brushes; not impossible, but certainly more challenging! But don’t worry because it’s never too late to learn.
### Real-World Applications of String Manipulation
Have you ever wondered why your favorite app shows your name in the greeting? Or how Google displays instant search suggestions based on what you type? String manipulation plays a significant role here, simply put, it’s everywhere!
## Understanding the C# Contains() Method
Moving on, let’s dig deep into the Contains() [method](https://www.bytehide.com/blog/method-usage-csharp). Consider it a detective in our C# world, helping us find out if a string contains another string. Interesting, isn’t it?
### Basic Syntax for Contains() Method
Here is the basic syntax for the Contains() method:
```csharp
//YourString is the string you want to check
//CheckString is the string you want to find
bool result = YourString.Contains(CheckString);
```
The function returns `true` if `CheckString` is found within `YourString`, and `false` if it is not. As simple as that!
### Real-World Application of C# Contains() Method
Imagine you’re developing a spell-checker app. Now, wouldn’t you need to check if the typed words are in your dictionary (string [array](https://www.bytehide.com/blog/array-csharp)) or not? There comes our `Contains()` method!
## How to Check in C# if A String Contains Another String
Now that we know what Contains() does, let’s get our hands dirty with some C# coding, shall we? In the next couple of sections, we’ll go over the procedure step by step, and I’ll also show you some examples. Are you ready?
### Step-by-Step Guide to Use Contains() Method
Here’s how you can find a string within another string:
```csharp
string YourString = "Hello world!";
string CheckString = "world";
bool result = YourString.Contains(CheckString); // returns true
```
Pretty straightforward, right? If `CheckString` (“world”) is present in `YourString`(“Hello world!”), the result will be true.
### Code Examples in C# to Check if a String Contains Another String
Let’s see another example:
```csharp
string YourString = "Hello world!";
string CheckString = "universe";
bool result = YourString.Contains(CheckString); // returns false
```
In this case, since `CheckString` (“universe”) isn’t part of `YourString` (“Hello world!”), the result is false.
## Checking in C# String Arrays for String Presence
But what if you have an array of strings rather than a single string? Do you need to iterate through each string in the array and use Contains()? Nope, because here we have another ace in the hole!
### Essential Guidelines on How to Use the C# Check if a String Array Contains Another String
In C#, you can directly check if an array of strings contains a specific string. Here’s how you do it:
```csharp
string[] YourStringArray = { "universe", "world", "earth" };
string CheckString = "world";
bool result = YourStringArray.Contains(CheckString); // returns true
```
It’s almost like the Contains() method for a single string, with the difference being that you apply it on an array.
### Efficient Coding Techniques for Checking if One String Array Contains Another
Wondering about checking if one string array contains another array? It’s achievable with a few extra lines of code:
```csharp
string[] YourStringArray = { "universe", "world", "earth" };
string[] CheckStringArray = { "world", "earth" };
bool result = !CheckStringArray.Except(YourStringArray).Any(); //returns true
```
If the `CheckStringArray` is a subset of `YourStringArray`, it returns true. Now, how cool is that?
## Addressing Common Challenges When Checking Strings
We all know, regardless of the programming language, coding does come with its fair share of challenges. It’s those challenges that make coding worth it, right?
### How to Troubleshoot Errors in Checking if String Contains Another String
Errors can happen, but it’s about learning from those errors and improving. What happens if the string you’re checking is null, or if it contains different cases (uppercase vs. lowercase)? Fear not as these issues are easily addressable:
```csharp
// Case-Insensitive Check
bool result = YourString.Contains(CheckString, StringComparison.OrdinalIgnoreCase);
```
The above code can help you overcome the case sensitivity issue, and as for null strings, always use `null` checks before using `Contains()`.
The benefits of mastering this technique are considerable. It can play a vital role in data validation, search functionality, and so many more applications. It’s like a secret weapon, ready to deploy when the situation demands.
So, keep exploring, keep coding, and until next time, happy learning! | bytehide |

Missteps in the selection, installation, or maintenance of stud bolts can compromise the entire structure, leading to costly repairs and even dangerous situations. By understanding and preventing these errors, construction professionals can maintain the highest standards of quality and safety.
## Using the Wrong Size Stud Bolts
Choosing the correct size of stud bolts is a fundamental step in any construction project. The size of the bolt must match the specifications required for the load and the materials being joined. Using the wrong size can lead to insufficient load-bearing capacity, which may cause the joint to fail. It is essential to measure accurately and select bolts that fit perfectly to avoid these issues. Mismatched sizes can result in loose connections or excessive stress on the bolts, ultimately compromising the structure's integrity.
## Incorrect Installation Techniques
Proper installation of stud bolts is crucial for their performance. Incorrect techniques, such as over-tightening or under-tightening, can significantly affect the bolt's ability to secure the joint. Over-tightening can cause the bolt to stretch or even break, while under-tightening can lead to a loose connection that fails under load. Following the manufacturer's guidelines and using the appropriate tools for installation can prevent these issues. Additionally, ensuring that the bolts are installed perpendicular to the surfaces they are joining will enhance their effectiveness and longevity.
## Ignoring Material Compatibility
The material of the stud bolts must be compatible with the materials they are fastening. Incompatible materials can lead to galvanic corrosion, where one metal corrodes faster than the other due to an electrochemical reaction. This can weaken the bolts and the joint they are securing. It is vital to select stud bolts made from materials that will not react adversely with the connected materials. Understanding the environment and conditions in which the bolts will be used, such as exposure to moisture or chemicals, is also crucial for making the right material choices.
## Skipping Pre-Installation Checks
Pre-installation checks are an essential step in ensuring the effectiveness of stud bolts. These checks include verifying the bolts' dimensions, inspecting for any damage or defects, and ensuring that the bolts and the surfaces they will join are clean. Skipping these checks can lead to issues such as improper fit, compromised structural integrity, and premature failure of the bolts. Taking the time to perform thorough pre-installation inspections helps identify and address potential problems before they escalate, ensuring a smooth and successful installation process.
## Neglecting Proper Lubrication
Lubrication plays a vital role in the performance and longevity of stud bolts. Proper lubrication reduces friction during installation, ensuring that the bolts can be tightened to the correct torque without excessive force. It also helps prevent galling, where the bolt threads seize due to friction and heat. Choosing the right lubricant for the specific application is crucial, as different environments and materials may require different types of lubrication. Regularly applying and maintaining the lubrication can also protect the bolts from corrosion and wear, extending their lifespan.
## Using Damaged or Defective Stud Bolts
Using damaged or defective stud bolts can have serious consequences for a construction project. Even minor defects, such as small cracks or deformations, can significantly weaken the bolts and compromise their ability to secure joints. It is essential to thoroughly inspect all stud bolts before use and discard any that show signs of damage or defects. Relying on high-quality bolts from reputable manufacturers can also help minimise the risk of defects. Ensuring that only sound, reliable bolts are used in construction projects is crucial for maintaining structural integrity and safety.
## Poor Maintenance Practices
Proper maintenance of stud bolts is essential for their continued performance and the overall safety of the structure. Regular inspections should be conducted to check for signs of wear, corrosion, or loosening. Any issues found should be addressed promptly to prevent further damage. Additionally, maintaining proper records of maintenance activities can help track the condition of the bolts and schedule timely replacements if necessary. Implementing a robust maintenance routine ensures that the stud bolts remain in good condition, providing reliable support for the structure throughout its lifespan.

Anyone knows, yes, this is known all over the world. But let me say, shell script is such a powerful.
I have tried some ways of initial setup my linux environment like `dotfiles repository`, `nix`, `chef`.
All of them are not so bad, but not perfect to me.
For example,
- `dotfiles repository` is separated from system package installation.
- I know that all I need is just preparing single install script.
- `nix` is easy but complex and too large to me, sometimes building package time is so long.
- `chef` is overspec for single host machine.
My requirements for setup are below.
- 100% for me
- I don't need a general system.
- Basically oneshot
- But I can setup as many times.
- Simple
- All I needed is just 2 layers of install packages and user configuration for packages.
- On Linux
- Use shell script, yeah.
- Always latest
- Arch like rolling release provides me this spec.
So, now I have had a non-difficut (for me) shell script of bash.
# Detail
I need 2 layers of `install` and `configuration`.
## Install
I defined `install` as 2 type of `standard install` and `custom install`.
### Standard install
`Standard install` is just package manager of OS built-in.
In Arch, via `pacman`. In Debian, via `apt`.
### Custom install
On the other hand `custom install` is user-defined installation like using `git`, `curl` or `make`.
## Configuration
I defined `configuration` is just configuration. No trick.
For example create a `.bashrc` symlink to `${HOME}`, create a `neovim` config directory symlink to `${XDG_CONFIG_HOME}/nvim`.
## Picture
## Constructure
So simple.
I put shell scripts for install and configuration and packages directory to detect my own necessary.
```txt
setup.sh
install_batch.sh
install_single.sh
configure_batch.sh
configure_single.sh
install_custom_batch.sh
install_custom_single.sh
configure_custom_batch.sh
configure_custom_single.sh
packages/
```
`packages` directories has subdirectory for each pacakges.
```txt
packages/
bash/
.bashrc
.bash_profile
configure.sh
install.sh
tmux/
tmux.conf
install.sh
configure.sh
...
```
And each implementations are like this. Basicly, I don't create functions intentinally for maintenance.
I decided that each shellscript files should be seemed as isolated module or namespace.
```bash
# setup.sh
sh "./install_batch.sh"
sh "./configure_batch.sh"
sh "./install_custom_batch.sh"
sh "./configure_batch.sh"
```
```bash
# install_batch.sh
pushd packages
for package in *
do
sh "${package}/install.sh"
done
popd
```
```bash
# <pacakge name>/install.sh
sh "$(sh install_command.sh) ${1}"
```
About `configure` is as same as `install`.
This design allows me do install or configuration isolated for single package like `sh ./install_single.sh podman`. 100% for me.
# Conclusion
Shell script is powerful to make modular system.
Though I don't write any tests, maybe I can write test easily. | mtwtkman |

It is a computing service that runs code in response to events and automatically manages the computing resources required by that code.
As a popular ETL service, Glue offers numerous options to connect to various databases, including PostgreSQL, which is a widely-used RDBMS.
Glue provides several ways to set up ETL (Extract, Transform, Load) processes, as shown below:
With its visual setup, performing ETL tasks becomes much easier.
You only need a few clicks to create an ETL job that helps transform data from an S3 input to a PostgreSQL output.
However, this setup has several restrictions because you need to follow all the available options before you can create a properly functioning ETL job.
If you are looking for more flexibility in configuration, you can consider using a script setup.
With a script setup, you can connect to your data source or output directly from the script. To do this, switch from the visual setup to the script page as shown below:
For the code, you can use simple scripts like the following:
```
import sys
from awsglue.transforms import *
from awsglue.utils import getResolvedOptions
from pyspark.context import SparkContext
from awsglue.context import GlueContext
from awsglue.job import Job
import boto3
# Initialize Glue context and job
args = getResolvedOptions(sys.argv, ['JOB_NAME'])
sc = SparkContext()
glueContext = GlueContext(sc)
spark = glueContext.spark_session
job = Job(glueContext)
job.init(args['JOB_NAME'], args)
# Read data from S3
s3_path = 's3://your-S3-REPO/'
datasource = glueContext.create_dynamic_frame.from_options(
connection_type="s3",
connection_options={"paths": [s3_path]},
format="csv", # Adjust format as necessary
format_options={"withHeader": True, "separator": ","}
)
datasource.printSchema()
# Transform data if needed (this is a simple pass-through in this example)
transformed = ApplyMapping.apply(
frame = datasource,
mappings = [
("id", "string", "id", "int"),
("name", "string", "name", "string"),
("age", "string", "age", "int")
]
)
transformed.printSchema()
# Write data to PostgreSQL
glueContext.write_dynamic_frame.from_options(
frame = transformed,
connection_type = "postgresql",
connection_options = {
"url": "jdbc:postgresql://your-PostgresqlDB-Endpoint",
"dbtable": "your_table",
"user": "your-Posgresql-User",
"password": "your-Posgresql-Password"
}
)
# Commit the job
job.commit()
```
And for the input, you can use a CSV format file like this:
```
id,name,age
1,John Doe,30
2,Jane Smith, 15
3,Bob Yellow,20
4,Roshan Brown,18
5,Bam Black,55
```
After that, you can start the job and wait until it finishes. If it succeeds, as shown below:
you can check the latest result in your posgresql.

My name is Dukwe David Onyamom, let me tell you of the first time I heard of coding, I believe I was in 8th grade and euphoric at the mention of coding cause when I found out a lot of my games were coded I thought to myself to create a perfect game and proceeded to Play store to download a game maker, as of when i first went to a proper institution to learn coding i understood how niave i was when i couldn't make a single object move in python without a kids program named scratch, but nevertheless the nostalgia from coding from scratch took me by storm that i forgot what i was pissed at first that i knew nothing, but what truly marveled me where the thousands of lines of code it took to make an object move that was when I truly gave respect to programmers for i had just experienced the pain of debugging a program, this shifted the whole course of my career path which made me do computer scicence for i thought that computer science was an undercover name for programming and coding but i was wrong
Upon me entering computer science I was greeted by previous secondary school subjects I hated such as biology at this point I was demotivated but pushed hoping the real coding would start after the 1st semester
I was wrong
As I came home for my first holiday my mom urged me to meet my uncle and learn python, I was already so happy that I was going to learn what I have been eager about for so long, as of when I got there each lesson was the most intriguing thing I've done in my life each time I spent hours solving problems in Python i felt truly happy, i vividly remeber when i made a random pysdo number game i was overjoyed but all that came to an end once the holidays were over and I'm the 2nd year was over and i heard my uncle closed due to private reason there was a brief closage in my coding journey .
I resumed later, learning coding as part of my IT. Learning HTML and CSS is actually really interesting and long. But I believe with time and hardwork I'd understand it.
Well let's see what the future holds. I've come to understand how deep HTML truly is and indepth the structure is, but to be honest its still stressful and with the way the world is evolving maybe 10 years in the future AI would have made it easier.
That's my Programming Journey, and for people who want to learn any programming language I say this "sometimes you'll cry but when you cry you play small blood strike and ride on"and I mean that it's not a get rich quick scheme you'll have to be dedicated.

1,878,688 | AWS Community Buildersになって変わったこと | 先日、私はAWS Community... | 0 | 2024-06-06T09:11:39 | https://dev.to/aws-builders/aws-community-buildersninatutebian-watutakoto-pkj | awscommunitybuilders, japanese, pankration, jawsug | 先日、私はAWS Community Buildersに3年連続で選出されました。
最初に選出されたのは2022年で当時は新型コロナウイルスが蔓延している中で、オンラインでの勉強会を中心に開催していました。その中でLINE Developer Communityとの共同企画を行っていたこともあり、Front-End Web & Mobileの分野で選出されました。
{% embed https://www.youtube.com/watch?v=gbrT0bEKHI4&t=548 %}
AWS Community Buildersになる前に[JAWS Pankration 2021](https://jawspankration2021.jaws-ug.jp/)という24時間イベントに登壇しました。このイベントは世界中のAWSユーザーグループを巻き込んだイベントで、フォロー・ザ・サン形式で開催された海外からもクレイジーと評価されたJAWS-UGのイベントでした。
そして、今回3年ぶりに[JAWS Pankration 2024](https://jawspankration2024.jaws-ug.jp/ja/)という形で開催されることとなり、Call for Proposalsに応募するにあたり、AWS Community Buildersになる前となった後でどのような違いがあったかについてまとめてみました。
{% embed https://www.youtube.com/watch?v=KNJtfqDl8g0 %}
# AWS Community Buildersとは
[公式サイト](https://aws.amazon.com/jp/developer/community/community-builders/)では以下のように紹介されており、[AWS Community Directory](https://aws.amazon.com/jp/developer/community/community-builders/community-builders-directory/?cb-cards.sort-by=item.additionalFields.cbName&cb-cards.sort-order=asc&awsf.builder-category=*all&awsf.location=*all&awsf.year=*all)にて選出された方が検索できるようになっています。2024/6/6現在で全世界で2,593人（日本人は120人）が公開されています。以前は半年に1度選出されていましたが、現在は1年に１回の選出サイクルとなっており、すでに選出されているビルダーでも毎年の更新のフォームに活動をアピールする必要があり、活動が評価されない場合には次年度の選出は行われません。
> AWS コミュニティビルダーズプログラムは、知識の共有や技術コミュニティとの連携に熱心な AWS 技術愛好家や新興のソートリーダーに、技術リソース、教育、ネットワーキングの機会を提供するプログラムです。

> AWS の内容領域専門家から、技術以外の様々なトピックについて学び、コンテンツ作成、CFP の提出や講演をする機会を確保するサポートを受けることができます。
> AWS プロモーションクレジット、コンテンツ制作や地域密着型の活動を支援する他の有用なリソースを得ることができます。
> サプライズです!
# なぜAWS Community Buildersに申請しようとしたのか
私は[JAWS-UG金沢支部](https://jawsug-kanazawa.doorkeeper.jp/)のコアメンバーをしています。AWS Community Day KanazawaやJAWS DAYS 2021の実行委員などを行う中で、AWSのコミュニティ担当の社員の方からもお声がけをいただくとともに、すでにAWS Community BuildersになられていたMasayuki KatoさんやMichael Tedderさんの影響を受けて申請することに決めました。
AWS Community Buildersは申請制度なので、自分で活動をフォームを通じて英語で入力する必要があり、2021年度は選出されませんでした。活動内容を第三者が理解できるようにアピールすることができなかったことが原因でした。
諦めずに半年間活動を続け、アピールする方法も見直すことで無事2022年に選出されました。
# AWS Community Buildersに選出された変化について
私の中で実感したことは以下の４点です。
## 最新情報に触れることができる
AWS Community Builders向けのミーティングなどがオンラインで開催されており、その中で最新のサービス情報に触れることができます。
ミーティングはタイムゾーンの都合上、２回に分けて開催されているのですが、日本時間では午前1時と午前７時に行われることが多く、APAC(アジア太平洋地域)のAWS Community Buildersにとってはリアル参加するのはなかなか大変です。
ただ、リアル参加を通じてチャットの盛り上がりなどを見るととても刺激になります。
## 英語への抵抗感が多少和らぐ
You Belong Hereの動画にある通り、私は英語がほとんどできません。そのため、ラスベガスで開催されているre:Inventに２回参加しましたが、いずれもホテルでトラブルに巻き込まれて英語が話せないことによってかなり苦労した経験をしています。
{% embed https://www.youtube.com/watch?v=dms7RlAPNDs?t=39 %}
AWS Community Buildersのお知らせは専用のSlackワークスペースにて全て英語でやり取りされているため、情報を理解するために英語に触れざるを得ない環境に置かれます。
ただ、幸いなことにlang-japaneseチャネルだけは日本語でやり取りされているので、細かい理解ができない場合には日本のAWS Community Buildersの助けを借りることもできます。
日頃英語で会話したり、文章を書いたりすることはないためこのような機会に接することは抵抗感が少しでも和らぐことにつながります。
## AWS re:Invent 2023の体験
[5年ぶりに自費で行ったre:Invent体験記](https://dev.to/aws-builders/5nian-burinizi-fei-dexing-tutareinventti-yan-ji-1d0e)で記載していますが、私はAWS re:Invent 2023でAWS Community Buildersになる前に行ったAWS re:Invent 2018との違いを実感しました。
AWSへの理解が広がったり、コミュニティを通じて関わるメンバーが増えたからということもありますが、AWS Community Buildersになっていなければ接することのなかった人とネットワーキングすることができました。
人と人が繋がることによって入ってくる情報もかなり変わることになります。私は技術的な領域での強みを持っているわけではないため、新たに繋がった方から入ってくる情報や考え方は日頃触れることができないものが多く、自分を変化させてくれる動機づけにつながります。
## AWS Community Buildersとの交流
海外との繋がりがAWS Community Builderの醍醐味ですが、国内のメンバーとの繋がりについては国内のイベントを通じて積極的に交流を持つようにしています。
昨年の取り組みでは、[AWS Summit Tokyo 2023](https://dev.to/aws-builders/aws-summit-tokyo-2023ti-yan-ji-4oe7)や[JAWS Festa 2023](https://dev.to/aws-builders/jaws-festa-2023ti-yan-ji-1a9m)でのAWS Community Builders専用の交流イベント AWS Community Builder Meetup を企画しました。
それぞれ技術的な強みを持つというところもありますが、コミュニティを支えている人たちだからこそ出てくる言葉に学びが多いことが事実です。
## 意識の変革
JAWS-UGの活動だけでなく、私はいくつかのコミュニティ活動を行っていますが、そんな私がコミュニティ活動をやっていて、「なぜ自分の時間と労力を投入して活動を行うのか」という大きな悩み事があります。
この思いは開催するイベントが大きくなればなるほど、そして中心的なメンバーが少ければ少ないほど、この思いは大きくなるように感じています。
熱量の高い人、楽しくしているところには人は集まるとよく言われますが、AWS Community Bildersのように求心力が高い方と一緒にコミュニティの活動を行うことによって、「なぜ自分の時間と労力を投入して活動を行うのか」の答えが見出せました。
# まとめ
AWSの技術を日頃から利用されている方でアウトプット活動が好きな方であれば、一歩前に踏み出すだけで世界は大きく変わります。ご覧いただいた内容を通じてやってみようと思われた方は、ぜひ[JAWS Pankration 2024](https://jawspankration2024.jaws-ug.jp/ja/)に応募してみてください。 | matyuda |

1,879,000 | Array Destructuring in JavaScript: Tips, Tricks, and Techniques | In JavaScript, array destructuring is a concise and elegant syntax for extracting values from arrays... | 27,607 | 2024-06-06T09:04:19 | https://dev.to/hkp22/array-destructuring-in-javascript-tips-tricks-and-techniques-26p9 | webdev, javascript, programming, react | In JavaScript, array destructuring is a concise and elegant syntax for extracting values from arrays into individual variables. It offers a significant improvement over traditional array indexing, making your code more readable, maintainable, and less error-prone.
{% youtube zBJQSjBOP4o %}
👉 **[Download eBook - JavaScript: from ES2015 to ES2023](https://qirolab.gumroad.com/l/javascript-from-es2015-to-es2023)**
.
**Unpacking Arrays with Destructuring**
Imagine you have an array containing information about a person:
```javascript
const person = ["Alice", 30, "Seattle"];
```
Previously, you'd access individual elements using bracket notation:
```javascript
const name = person[0];
const age = person[1];
const city = person[2];
```
Array destructuring allows you to assign these values to variables in a single line directly:
```javascript
const [name, age, city] = person;
```
Here's how it works:
- The square brackets `[]` indicate array destructuring.
- The variables `name`, `age`, and `city` are declared on the left-hand side (LHS) of the assignment.
- The order of variables in the destructuring pattern matches the corresponding order of elements in the array on the right-hand side (RHS).
- Values are extracted from the array and assigned to the respective variables.

[](https://qirolab.gumroad.com/l/javascript-from-es2015-to-es2023)
**Benefits of Array Destructuring:**
- **Improved Readability:** Destructuring makes code more self-documenting by explicitly associating variable names with array elements.
- **Conciseness:** It eliminates the need for repetitive bracket notation, especially when dealing with longer arrays.
- **Error Prevention:** By matching variable positions with array elements, you avoid potential indexing errors that can occur with traditional methods.
- **Flexibility:** Destructuring allows you to:
- Extract only specific elements you need.
- Assign default values to variables in case elements are missing.
- Capture the remaining elements using the rest parameter (`...`).
**Common Use Cases:**
1. **Extracting Specific Elements:**
```javascript
const colors = ["red", "green", "blue"];
const [firstColor, secondColor] = colors; // firstColor = "red", secondColor = "green"
const numbers = [1, 2, 3, 4, 5];
const [,, thirdNumber] = numbers; // thirdNumber = 3 (skips first two elements)
```
2. **Swapping Variables:**
```javascript
let x = 10, y = 20;
[x, y] = [y, x]; // Now x = 20, y = 10 (swapped values)
```
3. **Assigning Default Values:**
```javascript
const fruits = ["apple", undefined, "banana"];
const [firstFruit = "unknown", , secondFruit] = fruits; // firstFruit = "apple", secondFruit = "banana"
```
4. **Capturing Remaining Elements with the Rest Parameter (`...`):**
```javascript
const animals = ["cat", "dog", "bird", "fish"];
const [firstAnimal, ...otherAnimals] = animals; // firstAnimal = "cat", otherAnimals = ["dog", "bird", "fish"]
```
**Nesting Destructuring:**
[Array destructuring](https://www.youtube.com/watch?v=zBJQSjBOP4o) can be nested within other destructuring patterns to extract values from deeply nested arrays:
```javascript
const data = ["Alice", { age: 30, city: "Seattle" }];
const [name, { age, city }] = data; // name = "Alice", age = 30, city = "Seattle"
```
**Conclusion:**
[JavaScript array destructuring](https://qirolab.com/posts/javascript-array-destructuring-unpacking-arrays-with-ease) is a powerful tool that can significantly enhance your coding experience. By incorporating it into your codebase, you'll write code that is cleaner, more readable, and less prone to errors. So, embrace the power of destructuring and make your JavaScript journey more enjoyable!

1,878,865 | The Core Architectural Components of Microsoft Azure. | These building blocks provide the foundation for any Azure solution. Azure Regions Availability... | 0 | 2024-06-06T09:03:05 | https://dev.to/franklin_onuegbu/the-core-architectural-components-of-microsoft-azure-1138 | cloudcomputing, azure | These building blocks provide the foundation for any Azure solution.
1. Azure Regions
2. Availability Zone
3. Resource Group
4. Azure Resource Manager (ARM)
Let’s explore Azure Regions in more detail:
**What are Azure Regions?**
- Azure Regions are geographically distributed data centers where Microsoft Azure services are hosted.
- Each region is a separate geographic area with one or more data centers.
- Azure currently has 60 regions worldwide, spanning multiple continents.
- These regions are strategically placed to provide low-latency access to services for users and applications.
**Key Points:**
- Data Sovereignty: Organizations can choose the region where their data resides to comply with data sovereignty laws.
- High Availability: Azure services are replicated across regions for redundancy and disaster recovery.
- Performance: Selecting the nearest region improves performance by minimizing latency.
- Service Availability: Not all services are available in every region; some are region-specific.
- Region Pairs: Each region is paired with another for failover scenarios.
**Use Cases:**
- Global Applications: Deploy applications globally by leveraging multiple regions.
- Disaster Recovery: Use paired regions for failover and business continuity.
- Compliance: Ensure data compliance by storing it in specific regions.
Remember that choosing the right region impacts performance, compliance, and availability.
Let’s delve into Azure Availability Zones:
**What Are Availability Zones?**
- Availability Zones (AZs) are physically separate data centers within an Azure region.
- Each zone has its own power, cooling, and networking infrastructure.
- Zones are designed to be isolated from each other to prevent correlated failures.
- You can have a minimum of 3 availability zones.
**Key Points:**
- High Availability: Deploy resources across multiple zones for redundancy.
- Fault Domains: Each zone is divided into fault domains (groups of servers).
- Update Domains: Zones also have update domains (groups for planned maintenance).
- Applications: Distribute critical workloads across zones for resilience.
**Use Cases:**
- Mission-Critical Apps: Run applications that require high availability.
- Disaster Recovery: Use AZs for failover scenarios.
- Data Resilience: Store data redundantly across zones.
Remember, Availability Zones enhance reliability and ensure your applications stay up even during failures.
Let’s explore Azure Resource Groups:
**What Are Resource Groups?**
- Logical Containers: Resource Groups are logical containers that group related Azure resources.
- Management Scope: They allow you to manage, secure, and organize resources together.
- Billing Boundary: Resource Groups serve as a billing boundary for cost tracking.
**Key Points:**
- Grouping: Resources within a group share the same lifecycle (create, update, delete).
- Access Control: Apply RBAC (Role-Based Access Control) at the resource group level.
- Tags: Assign tags to resources within a group for better organization.
- Templates: Deploy resources together using ARM templates.
**Use Cases:**
- Project-Based: Group resources for a specific project or application.
- Environment Segmentation: Separate dev, test, and production environments.
- Policy Enforcement: Apply policies at the resource group level.
Remember, resource groups simplify management and help you organize your Azure resources effectively!
Let’s explore Azure Resource Manager (ARM):
**What Is Azure Resource Manager (ARM)?**
- Deployment and Management Service: ARM is Microsoft’s platform for managing and organizing resources within the Azure cloud.
- Consistent Management Layer: It offers a structured and efficient way to create, deploy, manage, and monitor Azure resources12.
**Key Concepts:**
- Resource: A manageable item available through Azure (e.g., virtual machines, storage accounts, web apps).
- Resource Group: A container grouping related resources for management.
- Resource Provider: Supplies Azure resources (e.g., Microsoft.Compute for virtual machines).
- Declarative Syntax: Describes desired infrastructure state using ARM templates (JSON files) or Bicep files3.
**Benefits:**
- Consistency: All requests handled through the same API, ensuring consistent results across tools.
- Security: Access control, tags, and locks for resource organization.
- Templates: ARM templates simplify resource provisioning.
- Regional Resiliency: New deployment model (Cloud Services extended support) provides regional resiliency for Azure Cloud Services4.

Its main idea is to showcase _traces_ across various technology stacks, including asynchronous communication via an MQTT queue. This week, I added a couple of components and changed the architecture. Here are some noteworthy learnings; note that some of them might not be entirely connected to OpenTelemetry.
Here's an updated diagram. New components appear in violet, and updated components appear in green.
I want to be able to add more components. Thus, I decided that instead of directly querying the database, the `inventory` component would query warehouses, which are supposed to be located in different regions. Each warehouse can be implemented in a different stack, and you can have as many as you want—PRs are welcome. I miss Elixir and .Net at the moment. The contract, which I need to write down, is easy:
* An endpoint `/stocks/${productId}`
* The ability to query PostgreSQL
* Return the stock in the form:
I've written about the changes in the inventory to account for the new configuration. Let's talk about the warehouse components.
## The Go warehouse
Let me be blunt: I dislike (hate?) Go for its error handling approach. However, with close to zero knowledge of the language, I was able to build a basic HTTP API that reads from the database in a couple of hours. I chose [Gin Gonic](https://gin-gonic.com/) for the web library and [Gorm](https://gorm.io/index.html) for the <abbr title="Object Relational Mapper">ORM</abbr>. OpenTelemetry provides an integration with a [couple of libraries](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation#instrumentation-packages), including Gin and Gorm. On the Dockerfile side, it's also pretty straightforward. I skipped optimizing the mount cache and the final base image, though I might return to it later.
All in all, that's the component I developed the fastest. I still dislike the Go language, but I begrudgingly understand that developers who want to get things done use it.
## The Ruby warehouse
While Ruby is not this famous anymore, I still wanted the stack in my architecture. I eschewed Ruby on Rails in favor of the leaner [Sinatra](https://sinatrarb.com/) framework. I use [sequel](https://sequel.jeremyevans.net/) for database access. The dynamic nature of the language was a bit of a hurdle, which is why it took me more time to develop my service than with Go.
I also spent a non-trivial amount of time on auto-instrumentation. For stacks with a runtime, auto-instrumentation allows developers to go on their merry way, oblivious to any OpenTelemetry concern. At runtime, the Ops team adds the necessary configuration for OpenTelemetry. For example, we achieve this with a Java Agent on the JVM.
I expected the same "carefree" approach with Ruby, but I couldn't find anything related to the stack. Ruby on Rails has a built-in plugin system, but not Sinatra. I tried to use `bash` to glue files together, but to no avail. If you're a Ruby expert or have any experience doing this, please let me know how.
## The GraalVM native warehouse
This one is a regular Kotlin application on Spring Boot with a twist: I'm using [GraalVM native image](https://www.graalvm.org/latest/reference-manual/native-image/) to compile ahead-of-time to _native code_. This way, I can use a tiny Docker image as my base, _e.g_, `busybox`. It's not as efficient as Go or Rust, but it's a good bet if tied to the JVM.
OpenTelemetry did work on the JVM version but didn't when I compiled it to _bytecode_. Given the compilation time, it took me a couple of days of back-and-forth to make it work. The reason is simple: Spring Boot relies on _auto configuration_ classes to activate or not features. Some auto-configuration classes rely on the presence of classes, others on the presence of beans, others on the opposite, others on existing properties, others on a combination of the above, etc.
In my case, the guilty class was `OtlpTracingConfigurations.ConnectionDetails`. It relies on the `management.otlp.tracing.endpoint` property:
```java
class OtlpTracingConfigurations {
@Configuration(proxyBeanMethods = false)
static class ConnectionDetails {
@Bean
@ConditionalOnMissingBean
@ConditionalOnProperty(prefix = "management.otlp.tracing", name = "endpoint")
OtlpTracingConnectionDetails otlpTracingConnectionDetails(OtlpProperties properties) {
return new PropertiesOtlpTracingConnectionDetails(properties);
}
}
```
If the property is not present **at compile-time**, the Spring Framework doesn't create a bean of type `OtlpTracingConnectionDetails`. Through a chain of missing beans, the final binary doesn't contain OpenTelemetry-related code. The solution is easy: set the property to an empty string in the `application.properties` file, and override it to its regular value in the Docker Compose file.
While auto-configuration is a compelling feature, you must understand how it works. That's the easy part. However, it's much more work to understand the whole chain of auto-configuration activation regarding a feature. Having distanced myself from the JVM, I'm no longer an expert in these chains, much less the OpenTelemetry one. I finally understand why some developers avoid Spring Boot and name it magic.
## Migrating from JavaScript to TypeScript
I used JavaScript in my first draft of a subscriber to the MQTT queue. Soon afterward, I decided to migrate to TypeScript. JavaScript code is valid TypeScript, so a simple copy-paste worked, with the addition of `@ts-ignore`.
However, when I tried to fix the code to "true" TypeScript, I couldn't see any OpenTelemetry trace. As for GraalVM, I went back and forth several times, but this time, I decided to solve it once and for all. I migrated code line by line until I isolated the issue in the following snippet:
```javascript
const userProperties = {}
if (packet.properties && packet.properties['userProperties']) {
const props = packet.properties['userProperties']
console.error('Props', props)
for (const key of Object.keys(props)) {
userProperties[key] = props[key] //1
}
}
```
1. The TypeScript compiler complains with the following error message: `TS7053: Element implicitly has an any type because expression of type string can't be used to index type {}`
I earlier tried to fix it with the following:
```typescript
const userProperties = new Map<string, any>()
```
It compiled, but my limited understanding of JavaScript prevented me from realizing that a `Map` is not the same structure as an object. I understood the issue only when I isolated the exact line that went wrong. I just had to find the correct syntax to declare the type of an object:
```typescript
const userProperties: Record<string, any> = {}
```
## Adding a Redis cache
So far, my services have used only PostgreSQL as a data store. Datastores don't implement OpenTelemetry by themselves, but the correct instrumentation of an app can show the trace going to the datastore. Here, you can see the trace created by the OpenTelemetry agent on a Kotlin/Spring Boot app that uses the PostgreSQL driver.
Here's the one from the Gorm framework, instrumented manually.
Both traces display the system, the statement, and a couple of other data. The Redis instrumentation shows the same information under the same structure!
Icing on the cake, if you use the Lettuce client, which is the default for Spring, you don't need additional changes. The OpenTelemetry agent already takes care of everything.
## Another Apache APISIX instance
Last but not least, I've added another APISIX instance. Most organizations manage their APIs from behind a single multi-node API Gateway. However, it can be a significant burden depending on how the organization structures the teams. When a team needs to deploy a new or change the routing of an existing non-front-facing API, they want the change ASAP. If the team in charge of the centralized API Gateway doesn't respond to tickets, it slows down the API team and the business value they want to deploy.
For this reason, it's a perfectly valid pattern to set up API Gateways that are not front-facing under the responsibility of each API team - or business department. The granularity here depends on what works for each organization. It reduces friction when the infrastructure needs to change but does so at the cost of more diversified work for the API team. It also allows for different API Gateway technology (or technologies) from the front-facing one.
In my demo, I assume the team responsible for the `inventory` component has set up such an instance. It handles all routing to the warehouses. All other components still rely on the primary APISIX instance.
## Conclusion
In this post, I've described several changes I made in my OpenTelemetry tracing demo and the lessons I learned. I want to add additional warehouse components in other stacks. What stack would you be interested in? Would you like to contribute to such a component?

1,852,411 | Update a Progress Bar using Turbo Streams (using Custom Actions) | This article was originally published on Rails Designer When Turbo Streams was announced they... | 0 | 2024-06-06T09:00:00 | https://railsdesigner.com/progress-bar-turbo/ | rails, ruby, hotwire, webdev | This article was originally published on [Rails Designer](https://railsdesigner.com/progress-bar-turbo/)
---
When Turbo Streams was announced they allowed you to do a handful actions, like prepend, replace, focusing on your HTML.
Fast-forward, and through [this PR](https://github.com/hotwired/turbo/pull/479) it's now possible to **create your own actions**. This means everything you can normally do with JavaScript you can do using Turbo Streams.
There is this [great article](https://marcoroth.dev/posts/guide-to-custom-turbo-stream-actions) by Marco Roth that explains the basics—check it out.
## Setting the stage
I have a report feature, that gathers data, does some calculations and then creates a PDF off of it.
This is some intensive data wrangling, so it makes sense to put it into one or many background jobs. For a great UX the goal is to **let the user know about the progress**.
What is needed:
- report model (`status: %w[pending ready]`);
- a stimulus controller to show the progress (`1..100%`);
- turbo stream, with custom action, to update the progress in the view.
This article will not cover every single detail to get this functionality up and running from zero, but only touches upon the important bits needed for [the requirements](#setting-the-stage).
Once the report is requested by the user, respond with a turbo_stream and inject a progress bar.
```ruby
turbo_stream.prepend("reports", partial: "reports/in_progress")
```
This will add the `reports/_in_progress.html.erb` add top of the `#reports` element.
```erb
<div>
<h3>Fasten your seatbelt! We're turbo-charging a dazzling data display just for you.</h3>
<span data-controller="progress-bar" data-progress-bar-amount-value="0" id="progress_bar" class="block w-0 h-2 bg-blue-500 rounded transition-all"></span>
</div>
```
This needs a Stimulus controller to update the progress bar. Let's create it.
```js
// app/javascript/controllers/progress_bar_controller.js
import { Controller } from "stimulus";
export default class extends Controller {
static values = { amount: Number }
connect() {
this.#updateProgress();
}
// private
amountValueChanged() {
this.#updateProgress();
}
#updateProgress() {
this.element.style.width = `${this.amountValue}%`;
}
}
```
All this Stimulus controller does is change the width of its element whenever the `data-progress-bar-amount-value` changes. This is because of the `amountValueChanged()` function.
Now in each step of the report creation, fire off a turbo_stream to update the amount data attribute.
Let's imagine the following object:
```ruby
# app/models/report/creator.rb
class Report::Creator
def initialize(report)
@report = report
end
def create
collect
wrangle
# …
finish!
end
private
def collect
# collect data
update_progress(amount: 1)
end
def wrangle
# wrangle data
update_progress(amount: 10)
end
# etc.
def finish!
@report.ready!
update_progress(amount: 100)
# TODO: probably update the screen with button to download the report
end
def update_progress(amount:)
action = turbo_stream_action_tag(:set_dataset_attribute, value: value)
ActionCable.server.broadcast("reports", action)
end
```
In each “step” the `update_progress` method is called. This method needs some explanation.
First it uses `set_dataset_attribute` from [turbo-power](https://github.com/marcoroth/turbo_power). It's a great add-on to your Turbo-powered Rails app.
It then broadcasts the created action to the "reports" stream (make sure you add it!). I've not stumbled upon another working solution, but am curious if you know of any.
And these are all the high-level steps needed to get a great UX for long-running background jobs. I think it's pretty great **this is now possible with almost no JavaScript written**! | railsdesigner |

Here are 12 tips from my digested experience starting an online business.
## Assess your idea's feasibility!
Every invention begins as a thought. Your idea should confidently answer questions like;
- Is there a need for your business? Can your service or product solve a problem for many people?
- Can your business offer a cost-effective fix to that challenge?
- Are your potential customers willing to spend money to solve that problem?
- What costs would be involved to create the solution and still make a profit?
## Use Lean Canvas and SWOT analysis for your business plan
A workable idea forms the foundation when you build an online business. The next logical step is a business plan and strategy. I prefer Lean Canvas to a formal document with many pages people won't read.
Focus on eliminating waste, i.e., waste of time, processes, admin, etc. You can achieve this by being 'lean' in every way possible. The lean canvas will show your business model's crucial aspects in one actionable page.
Add in some simple SWOT analysis for good measure, and you're on the way to building something special.
## Think about an appealing brand name.
Creating a unique name is crucial when starting an online business.
You will compete against competitors fighting for the same market share. It's all about which brand is good enough to attract and keep new customers. A brilliant name is one method of achieving this.
An appealing brand name is short, easy to spell, memorable, and scalable.
Consider the domain name. Your business name can be different from your domain name. In either case, the same rules apply. Prioritize the ".com" extension and learn more about acquiring a cheap but great domain.
## Stupidly Simple Design
Simplicity is the name of the game when it comes to web design. This simplifies navigation and enhances faster page loading times, among many other benefits.
I recommend using stock images and taking inspiration from your favorite sites. I have some high-yield detailed tips to help you make simple and beautiful designs.

## Be a Criminal.
There will be a lot of legal stuff to sort. However, it's best to first focus on other things. The most important task is to get your business running, irrespective of how scrappy it may seem.
There are general guidelines that guide you through this process.
Register your business. Have necessary licenses (if required). Be mindful of the business type you choose. You can choose a sole trader, a limited liability, or a partnership.
There are details you must incorporate on your website. These are your trading name, email address, physical address, and registration number.
The website should include terms of service, a risk disclaimer, a privacy policy, a cookie policy, and a return policy for e-commerce businesses. Adhere to the necessary data protection policies.
## Develop and implement pre-launch marketing strategies.
A new enterprise will have a hard time standing out from the competition. Get your marketing on point, especially at the launch phase.
I always think of how to sell it before I make it. It's about finding strategies that keep your clients coming back for more. I use unique strategies to market Goleko. Read Crazy Marketing Strategy Goleko.com to gain unique insights that can be implemented in your marketing strategy.
## Social Media Marketing for your website.
It's crucial to drive people to your websites. That's where Social Media Marketing (SSM) comes in.
There are several types of marketing. Most companies focus on social media platforms. They focus less on non-digital channels like radio, TV, and newspapers.
There are several billion people on social media. Promoting your business on social media is beneficial to drive traffic to your site.
Read: *[Developing Content for Every Stage of the Customer Journey.](https://martinbaun.com/blog/posts/developing-content-for-every-stage-of-the-customer-journey/)*
## Make your website attractive to search engines.
Search engines like Google are crucial to generating organic traffic. Target each of your pages for the main keywords, incorporate internal linking, acquire backlinks, and create quality content.
I prioritize the highest page-loading speed and responsiveness for web and mobile. Get verified by search engines, run paid ads, and get indexed. I ensure relevant pages can run without JavaScript.
## Consider regular and relevant content publishing.

This leads to more customers knowing your business, increasing their chances of purchasing your product or service.
The key is knowing what clients want to read and how that drives interest in your business. Your content needs to be fresh and evergreen.
## Follow your customers and subscribers with e-mails.
E-mail is one of the best marketing strategies for small businesses. It's cheaper than print, radio, and TV.
Billions of people have e-mail accounts, and it is highly targeted.
People opting for an e-mail list show commitment and interest in your company. This improves conversion rates.
## Increase your income through back-end sales and upselling.
Upselling is one of the oldest tricks to building any business. Customers are likely to buy from the same company after their first purchase, assuming they are happy.
A business makes much of its income from loyal customers. I use upselling strategies like suggesting relevant products or services that complement the initial sale, offering upgrades, and using discounts or loyalty points on future orders (e-mail marketing ties in nicely here).
## Use of webmaster tools/analytics.
Consistently analyze your website. A webmasters or web analytics tools are necessary. They help you track the number of visitors daily, weekly, and monthly.
They also track the number of page views, bounce rate, time spent by your visitors on each page, broken links, page download time, number of backlinks, and crawling for errors that make your site less SEO-friendly.

Known for its innovative design, superior support and comfort, the Z1 knee brace has been highly appreciated by athletes, fitness enthusiasts and people who want to get rid of knee discomfort. So what makes the Z1 knee pads stand out from the competition? Let's examine the features and benefits of the Z1 Body Arm and explain why they are considered the best in their class.
Understanding knee pain:
Before we examine the basics of knee braces, it is necessary to understand what causes knee pain. The knee is a joint that supports weight and allows a wide range of motion. As a result, it is subject to many injuries and conditions, such as torn ligaments, cartilage damage, and osteoarthritis. It causes swelling, instability and osteoarthritis. This disorder can range from mild to severe and can affect mobility and overall quality of life. There are many types, including sleeves, wraps, and hinged braces, and each type has a specific purpose depending on the individual's needs and the nature of the knee injury or pain.
Support and stability:
One of the main functions of knee braces is to provide support and stability to the knee joint. By compressing the space around the knee and providing external support, braces help reduce stress and prevent further injury. This added stability is especially beneficial for people recovering from an accident or torn ligament, such as an ACL or MCL injury.
Compression and Pain Relief:
Knee braces apply gentle pressure to the surrounding tissue, helping to reduce swelling and reduce pain. By compressing the area, the stent provides a better and easier way to deliver oxygen and nutrients to the injured tissue while removing metabolic waste. This reduces pain and discomfort, allowing the person to function more easily each day.
Adjustment Correction:
If knee pain is caused by misalignment or biomechanical issues, some types of knee braces (such as off-load supports) can cooperatively help correct and redistribute weight. This relieves pressure on certain areas of the knee, thereby reducing pain and improving overall function.
Improving proprioception:
Proprioception is the ability to recognize the body's position and movement in space. Knee pads, especially those with adjustable straps or hinges, can improve posture and give people a better sense of coordination and mobility. This increased awareness improves balance, stability, and coordination, reducing the risk of falls and further injury.
Psychological Support:
In addition to its physical benefits, knee braces can also provide psychological support to knee patients. Additional protection and support can increase security, confidence and reduce stress, allowing people to remain calm and participate in daily life.
In summary, the Z1 knee brace represents the pinnacle of excellence in knee support and rehabilitation. With their innovative design, fit, good support and many features, these corsets offer a perfect solution for people who want to get rid of knee pain. Whether you're recovering from an injury, managing a chronic condition, or working to prevent future problems, Z1 knee braces provide the support, comfort, and performance you need to help you regain your strength and live life to the fullest. Find out the difference for yourself and find out why the Z1 knee brace is widely considered the best in its class.

1,878,977 | HTTP 1.1 vs 2 vs 3 | HTTP: The Internet's Language for Sharing Information HTTP, or Hypertext Transfer... | 0 | 2024-06-06T08:42:43 | https://dev.to/saikumar2121/http-11-vs-2-vs-3-370f | ## HTTP: The Internet's Language for Sharing Information
HTTP, or Hypertext Transfer Protocol, is the internet's language for sharing information. It works like a messenger between your web browser or mobile app (the client) and the web server (where websites are stored). When you want to see a webpage, your client sends an HTTP request to the server, asking for the page. The server then responds with an HTTP reply, giving you the page you asked for. It's the internet's way of making sure you can access all sorts of content online.
## The Evolution of HTTP: From 1.1 to 2 and 3
The Hypertext Transfer Protocol (HTTP) has come a long way since its inception, powering the World Wide Web's data exchange. In this article, we'll explore the evolution of HTTP through its various versions, including HTTP/1.1, HTTP/2, and HTTP/3, discussing their release dates, features, benefits, drawbacks, and real-world examples.
## HTTP/1.1
HTTP/1.1, standardized in 1996 and fully documented in 1997, was the first major version of the protocol widely used across the internet. It introduced persistent connections, allowing multiple requests and responses over a single TCP connection, thereby reducing latency. However, it had its limitations.
**Drawbacks**:
1. Head-of-Line Blocking (HOL): In HTTP/1.1, requests and responses had to be processed sequentially, leading to HOL blocking. When one request faced a delay, subsequent ones had to wait, hampering overall performance.
2. Text-Based Communication: All data, including headers, was transmitted in plain text, leaving room for security vulnerabilities.
**Real-time Example**:
> Consider a queue of cars at a toll booth. If one car experiences a delay, it holds up the entire line, similar to HOL blocking in HTTP/1.1.
## HTTP/2
HTTP/2 emerged in 2015 as a significant improvement over its predecessor.
**Benefits**:
1. Multiplexing: HTTP/2 introduced multiplexing, allowing multiple requests and responses to be sent concurrently over a single connection, eliminating HOL blocking.
2. Header Compression: It reduced overhead by compressing headers, enhancing efficiency.
3. Faster Page Loading: Web pages load faster, providing a better user experience.
**Drawbacks**:
1. HTTPS Requirement: Some features of HTTP/2 require secure connections (HTTPS), which could pose challenges for some websites.
2. Infrastructure Changes: The transition to HTTP/2 often required updates to server infrastructure, potentially causing adoption hurdles.
**Real-time Example**:
> Imagine HTTP/2 as a high-speed freeway where multiple cars (requests) can travel simultaneously without congestion.
## HTTP/3
HTTP/3, with its first draft published in 2019, represents the next step in the evolution of HTTP. It introduces significant changes
**Benefits**:
1. Elimination of HOL Blocking: HTTP/3 eliminates HOL blocking at the transport layer by adopting the QUIC transport protocol.
2. Enhanced Security and Performance: It offers improved security and performance.
3. Reliability on Poor Networks: HTTP/3 ensures a better user experience even on slow or unreliable networks.
**Drawbacks**:
1. Ongoing Adoption: HTTP/3 adoption is still in progress, with websites and services gradually transitioning.
2. Compatibility Issues: Some older systems and browsers may not fully support HTTP/3, causing potential compatibility challenges.
**Real-time Example**:
> HTTP/3 can be likened to a high-speed train network that avoids congestion entirely, ensuring swift and efficient travel.
## Why Not Everyone Adopts the Latest Version?
Although HTTP/3 offers significant benefits, not all websites and applications have transitioned to it. Reasons vary:
1. Compatibility: Moving to a new protocol often requires infrastructure updates and HTTPS adoption, which can be complex and costly.
2. Early Adoption Concerns: Some prefer to wait until a protocol matures and gains wider support.
3. Legacy Systems: Older systems may not support newer protocols, necessitating gradual migration.
**Pipelining: An Unrealized Dream**
HTTP/1.1 introduced pipelining to allow concurrent requests and responses, but it didn't work as expected due to HOL blocking. Browsers began using multiple connections to circumvent this limitation.
**Real-time Example**:
> Think of pipelining as a highway where cars can theoretically drive in quick succession, but congestion on a single lane results in delays, similar to HTTP/1.1's pipelining challenges.
## Extra Insights
1. Security Improvements
With each iteration, HTTP has improved in terms of security. HTTP/2 requires encryption (HTTPS) for its advanced features, and HTTP/3, built on QUIC, enhances security by incorporating encryption by default.
2. Performance Enhancements
HTTP/2’s multiplexing and header compression significantly reduce latency and bandwidth usage, while HTTP/3's use of QUIC not only eliminates HOL blocking but also reduces connection setup time, further enhancing performance.
**Real-world Adoption Examples**
1. HTTP/2: Major websites like Facebook, Google, and YouTube have fully adopted HTTP/2, significantly improving user experience by reducing page load times.
2. HTTP/3: Cloudflare, Google, and Facebook are among the early adopters of HTTP/3, leveraging its benefits to provide faster and more secure browsing experiences.
## Conclusion
The evolution of HTTP from 1.1 to 2 and 3 reflects the dynamic nature of the web. Each version has brought performance improvements, with HTTP/3 poised to redefine web communication. While adoption challenges exist, the advantages of faster, more secure, and efficient web browsing make the transition worthwhile. As the internet continues to evolve, staying informed about the latest protocols is crucial for web developers and users alike. | saikumar2121 | |
