1,880,054 | CORE ARCHITECTURAL COMPONENTS OF AZURE By OMONIYI, S. A. PRECIOUS | INTRODUCTION The core architectural components of Azure may be broken down into two main groupings as... | 0 | 2024-06-07T09:04:32 | https://dev.to/presh1/core-architectural-components-of-azure-12gc | physicalinfrastructure, managementinfrastructure | **INTRODUCTION**
The core architectural components of Azure may be broken down into two main groupings as below;
1. The Physical Infrastructure
2. The Management Infrastructure.
**1. THE PHYSICAL INFRASTRUCTURE**
The physical infrastructure for Azure starts with datacenters. Conceptually, the datacenters are the same as large corporate datacenters. They’re facilities with resources arranged in racks, with dedicated power, cooling, and networking infrastructure.
As a global cloud provider, Azure has datacenters around the world. However, these individual datacenters aren’t directly accessible. Datacenters are grouped into Azure Regions or Azure Availability Zones that are designed to help you achieve resiliency and reliability for your business-critical workloads.
**REGIONS**: A region is a geographical area on the planet that contains at least one, but potentially multiple datacenters 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 a resource is deployed in Azure, you'll often need to choose the region where you want your resource deployed.
**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.
**2. THE MANAGEMENT INFRASTRUCTURE**
The management infrastructure explains how the Azure Infrastructures are being managed, This includes Azure resources and resource groups, subscriptions, and accounts. Understanding the hierarchical organization will help in projects and products planning with within Azure.
**RESOURCES**: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 GRUOPS**: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.
**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. U
sing 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.
**AZURE RESOURCE MANAGER**:Azure Resource Manager (ARM)
The deployment and management service for Azure
Key Points
● Provides a unified way to manage Azure resources ● Allows users to create, update, and delete resources as a group ● Uses templates to automate deployment

1,880,150 | pSEO - Programmatic SEO Quick Intro with Examples | TLDR: pSEO automates the creation of web pages at scale for specific keywords. It's useful for... | 0 | 2024-06-07T09:00:57 | https://dev.to/vallu/programmatic-seo-pseo-quick-start-examples-41n3 | pseo, seo, webdev, automation | **TLDR:** pSEO automates the creation of web pages at scale for specific keywords. It's useful for businesses targeting various locations or services. For example:
- _Tyre shops in `<city>`_
- _Stock price of `<company>`_
- _Alternatives to `<product>`_
It's a powerful tool, but there are risks. If done carelessly you can be flagged as spam.
# What is Programmatic SEO and Do I Need It?
Programmatic SEO (pSEO) is a strategic approach that involves the automatic or semi-automatic generation of web pages to target specific keywords relevant to your business.
This technique leverages data and automation to create numerous pages that are optimized for search engines, thus enhancing the chances of appearing in search results for a broad range of keywords.
For example, you might have seen websites with individual pages for all cities:
- barber shops barcelona
- barber shops madrid
- barber shops `<city_name>`
- etc.
The page template is identical between the hundreds of city pages, but dynamic parts have been programmed into them. That means parts of the pages change between cities but for the most part they are identical copies.
So what's it good for and do you need it?
### Why You Might Need Programmatic SEO:
- **Scalability:** If your business covers a wide range of topics or products, manually creating pages for each keyword can be time-consuming and inefficient. pSEO allows for scalable content creation.
- **Efficiency:** Automation reduces the workload on your content creation team, freeing them up to focus on more strategic tasks.
- **Competitive Edge:** By covering more keywords, you can stay ahead of competitors who rely solely on manual SEO efforts.
# How Does Programmatic SEO Get You More Visitors?
Programmatic SEO boosts visitor numbers by systematically targeting a multitude of high-volume keywords. This is achieved through:
**1. Broad Keyword Coverage:**
pSEO enables you to cover a wide range of keywords that might be overlooked in manual processes. Each automatically generated page targets a specific keyword, e.g. all major cities relevant to your business.
For example you can use pSEO to create individual city pages:
- tyre shops helsinki _(/tyre-shops/helsinki)_
- tyre shops stockholm _(/tyre-shops/stockholm)_
- tyre shops oslo _(/tyre-shops/oslo)_
- etc.
This increases the likelihood of appearing in search results, as users are typically interested in city specific results.
**2. Efficient Use of Resources:**
With pSEO, you can create thousands of pages in the time it would take to manually produce a handful. This efficiency translates to a more comprehensive online presence.
**3. Data-Driven Content:**
By utilizing structured data, pSEO can help you fill each page with relevant and valuable information, enhancing user experience and boosting search engine rankings.
Of course there are risks of appearing spammy if pSEO isn't done thoughtfully.
# Example of a website heavily using pSEO
Dictionaries and synonym databases are a type of website that understandably rely almost entirely on programmatic SEO.
As their content is in an easily accessible format in a database, it can be pulled to create pages for each word.
As an example take a look at _anotherwordfor.xyz_ which utilizes pSEO to generate pages like:
- [Another Word for Important](https://anotherwordfor.xyz/important)
- [Another Word for Because](https://anotherwordfor.xyz/because)
- [Another Word for However](https://anotherwordfor.xyz/however)
In addition to this, they also have manual SEO pages like:
- [Perfect adjectives to describe a person](https://anotherwordfor.xyz/adjectives-to-describe-person)
If you look closely, you might identify parts even on manually created SEO pages that can be semi-automated. Have a look at the adjective lists on the above page.
# How to Get Started with Programmatic SEO?
**1. Keyword Research:**
Identify high-volume, low-difficulty keywords relevant to your business. Tools like Ahrefs and SEMrush can help pinpoint these keywords.
**2. Data Collection (super important!):**
Gather data that can be used to populate your programmatically generated pages. This could include product details, reviews, user-generated content, or other structured data relevant to your industry.
**3. Template Creation:**
Develop templates for your pages that can dynamically incorporate your collected data. Ensure these templates are SEO-friendly and provide a good user experience.
**4. Automation Tools:**
Use automation tools and platforms to generate the pages. Examples include Python scripts, pSEO plugins, or custom solutions tailored to your needs.
# Where to Find Keywords for Programmatic SEO?
**1. Keyword Research Tools:**
Utilize tools like Ahrefs and SEMrush to discover keywords with high search volume and low competition. These tools also offer insights into related keywords and search trends.
**2. Google Autofill and Search Suggestions:**
Google’s search bar suggestions and related searches at the bottom of search results pages are excellent sources for identifying commonly searched keywords.
**3. Competitor Analysis:**
Analyze the keywords your competitors are targeting. Tools like SEMrush and Ahrefs can provide detailed reports on competitor keywords, helping you identify gaps and opportunities.
**4. SERP Analysis:**
Review the search engine results pages (SERPs) for your target keywords to understand the type of content that ranks well. This can guide your content creation strategy.
# How Much Does Programmatic SEO Increase Visitor Count?
Programmatic SEO can significantly increase visitor count by allowing your site to appear in search results for a vast number of keywords. The key benefits include:
**1. Enhanced Visibility:**
More pages targeting relevant keywords mean more opportunities for users to find your site.
**2. Increased Traffic:**
With more targeted keywords, you attract a broader audience, which can lead to higher traffic volumes.
**3. Better User Engagement:**
By providing content that meets user needs and search intent, you can improve engagement metrics, such as time on site and pages per visit, which further boosts SEO performance.
**4. Measurable Results:**
Track the performance of your programmatically generated pages using analytics tools to refine and optimize your strategy continuously.
# What Drawbacks Does Programmatic SEO Have?
While powerful, programmatic SEO comes with potential drawbacks that need careful consideration:
**1. Risk of Low-Quality Content:**
Automated content can sometimes lack the depth and quality of manually created content. It’s essential to ensure that the generated pages provide value to users.
**2. Potential for Penalties:**
If programmatic SEO is done in a spammy or manipulative way, it can lead to penalties from Google. Ensure your practices adhere to Google’s guidelines and focus on user experience.
**3. Over-Reliance on Automation:**
While automation is beneficial, relying solely on programmatic SEO can neglect the nuanced and creative aspects of content creation. A balanced approach, combining both manual and automated efforts, is often the most effective.
By understanding and addressing these potential pitfalls, marketers and entrepreneurs can effectively leverage programmatic SEO to enhance their online presence and drive more traffic to their websites. | vallu |

## Introduction
On the 7th and 8th of March we were at the Open Source Day organised by [Schrödinger Hat](https://www.schrodinger-hat.it/), and it was a two-day conference full of enthusiasm and innovation in the framework of the innovative Nana Bianca coworker space in Florence, but if you were not there you can at least follow on YouTube their amazing talks https://www.youtube.com/@SchrodingerHat/streams or https://www.youtube.com/@SchrodingerHat/videos and the agenda https://2024.osday.dev/it/agenda.
As you can see there were a lot of amazing ones and I will try to help you decide which talk you should definitely follow.
## Technology Trends
There were 2 main trends:
- **AI tools**, especially LLM related ones, how to build LLM RAG based applications using open source tools from **Hugging Face and Ollama**.
- **WebAssembly** and its wider implications for software development.
And there was also a "shadow trend", not an explicit trend, but an ecosystem of similar technologies, namely:
- **CDC (change data capture), CRDT (conflict-free replicated data types) and concurrent collaboration or real-time update platforms**.
If you don't have experience with these tools, I recommend Stefano Fiorucci's talk on what an LLM application is, how it works, how to implement it, what it is and how to implement *Retrieval Augmented Generation* applications with **Haystack**, our **Edoardo Dusi** with his talk on WebAssembly, how it works and how it could become a new future standard due to its interoperability, versatility and great performance, Wasm component wrappers, integration with Docker and Kubernetes and much more, and Federico Terzi with a technical explanation of CRDT and what challenges you need to face to achieve real-time collaboration utilities.
## My favourite technology tool talks
I will briefly report on my favourite talks and start with some lesser known extensions to a very famous tool, Iulia Feroli's talk, Senior Developer Advocate at **Elastic**, showed us how easy and powerful Elasticseach could become with the use of some specialised clients allowing us to perform sentiment analysis and semantic search for example.
Sentiment analysis is an NLP technique that allows you to identify the positive or negative polarity of a given query, while semantic search is the search or ranking of content based on contextual relevance and intent.
For example, you could analyse a list of customer comments and intercept those that could lead to an escalation, or perform a search without having to know the exact terminology (e.g. a search for 'brave' could also return 'courage' and so on).\
The client used to import LLM into Elasticsearch was **Eland**, the ELSER NLP model was used to perform semantic searches, she also did a little briefing on how vertex search allowed us to perform semantic searches and remembered that vertex search could also be used to search for similar images for example.
Noam Honig, creator of **Remult** showed us a new way from backend to frontend, a full-stack CRUD framework that removes all code duplication between frontend and backend like dtos creation, data validation and so on, providing ORM-like database interaction and archiving a Typesafe and DRY architecture. With a live coding session, he showed us how fast it is to build a full-stack application with Remult. It has a lot of features, but the one I find most interesting is the ability to do live queries, long-lived queries that automatically update as results change. It can be integrated with many JavaScript frameworks and many databases.
Give it a try, maybe with fast prototyping, and you will love the philosophy behind this tool with a clear focus on improving the *developer experience*.
Mario Fiore Vitale, Senior Software Engineer at **Red Hat**, talked about **Debezium**, an open source platform that enables Change Data Capture (CDC), the ability to intercept changes in your database and propagate them across different systems, which could be very useful for synchronising multiple linked data sources, data replication, updating or invalidating a cache, updating search indexes, data synchronisation or propagating database changes via Kafka or a WebSocket. CDC enables incremental loading and eliminates the need for bulk updates. Debezium captures database changes by monitoring the database transaction log, so it doesn't impact the database itself.
Other interesting technologies included **Nanocl**, a Rust alternative to Kubernetes that grew out of a study project, Irine Kokilashvili's talk, **Camunda**, a tool based on business process modelling (BPM), which is a way to orchestrate and describe complex microservices processes and flows, as shown by Samantha Holstine, **LavinMq** a very performant message broker described by Christina Dahlén, **Scrapoxy** the amazing web scraping Swiss knife by Fabien Vauchelles and finally Graziano Casto showed us **Rönd**, a lightweight Kubernetes sidecar that distributes security policy enforcement throughout your application based on OpenPolicy Agent.
## A broad view of the conference
As you can imagine, an open source conference doesn't just focus on tools, but also on **high-level analysis** and experiences of open source development.
There was a focus on **accessibility** in a broad sense, not only for people with disabilities, but also for people with neurodivergence or temporary disabilities for example, and how to create an environment that helps them to be productive and satisfied with their work, improve their development experience and develop an inclusive workplace.
Also, although it hurts, I learned that Linux doesn't currently have great accessibility tools, so if you want to start an open source project for Linux, consider that we're trying to fill that gap!
Another topic was what open source is, its different forms, how to monetise or develop a business model for an open source project, how to protect it from being appropriated by big vendors and the **differences between FOSS and OSS**.
They also talked about the **security of the software supply chain** and how reliable open source technologies can be, with a presentation on the use of Linux in space missions.
There was also space for ethics, like a UNICEF talk on the challenge of making digital solutions and services accessible and 'profitable' for the most vulnerable, and also a focus on web sustainability, like that of our **Valeria Salis**, who wasn't able to be present at the event, but which you can watch from this link https://www.youtube.com/watch?v=KWK8Upl9-wU.
I would also like to focus on the talk by Andrey Sitnik, the maintainer of a widely used library such as **Post-CSS** and so on, who gave us a complete manual on how to manage an open source project, recalling how it is fully linked to relationship management, the need to give quick feedback, to trust contributors and to consider them as the people behind what they are asking for, inviting us to empathise with them, to gain insight into why, for example, your detailed documentation is never read as carefully as you expected, or to understand why some projects that you thought might be more popular are instead ignored despite their potential, to remember how the adoption of a framework or so on depends more on irrational processes than cold analysis.
## Why Open Source
What emerged from the talks was **enthusiasm and positivity**, open source as a tool that could spread values of commitment, collaboration and tolerance, and develop social communities of mutual respect and status quo challenging innovation, a kind of friendly world utopia, a tool to indirectly promote a better world.
As PJ Hagerty's talk points out, don't expect this to always be true, we need to foster good open source citizenship ourselves first.
Nowadays many companies claim that their products are OSS as a marketing strategy, but this is not always completely true (especially for some AI tools) and some big projects started to change their licences to some more restrictive or sometimes closed ones.
However, **open source adoption is still very high** and it's growing, with more than 90% of developers relying on open source components in their proprietary applications.
But probably in the future, the need to protect large projects from being forked and the business models of the companies behind them, the adoption of open core strategies will change the definition of open source and it will only define projects where the source code is public/available for inspection and there will be a clear distinction between OSS and FOSS where redistribution will be free.
Until then, open source is still a philosophy, and to embrace it, to claim it, is to have a mentality around it.
And speaking of mentality, I want to focus on a term that is rarely quoted, but I think it should be a core concept related to OSS, and that is the **autotelic concept**.
Autotelic is an adjective that describes *activities that exist for their own sake*, because experiencing them is the main goal, but also people who do things moved by intrinsic motivation, not by wealth, fame, power research, not by concern for money, status, applause or recognition by others, and it's linked to the ability to experience flow more often and is used to describe some art, sport or play activities.
This perspective overwhelms the idea of **contributors being driven by ego**, which is relevant in open source development.
Public opinion perceives OSS as a tool that promotes free culture and considers it to be a more transparent system, and therefore a more secure system, without any dark patterns inside.
Can free access to source code be a professional standard in the future, demanded by people in the same way that we demand the components of a medicine in the package leaflet?
We don't know yet, a lot will depend on how events affect public opinion, whether people start to care more about concepts like their privacy and whether they start to trust open source software more than proprietary software.
**Will FOSS continue to exist?** Probably yes, because libraries or tools for developers focus on usage and if they're free it's easier for them to be adopted, also the development of these tools gives prestige to the people or companies that have worked on them and is also a way to create a process of continuous improvement.
The affirmation of open source lies in the transformation of users into active actors, able to report bugs and sometimes suggest new features, and this is very common in tools for developers, but still a little lacking in general-use tools for the general public.
There are also adoptions of the open source model outside of software development, such as in the arts or education, which probably need more resonance, and we probably need to spread the open source mentality beyond the boundaries of software development.
There are several challenges to overcome, but we hope that open source will be able to flourish, because **"a mind is like a parachute. It doesn't work if it's not open"** - and that certainly applies to software!

How to customize the labels of a pie chart in VChart?
# Description
Can the labels of a VChart pie chart be customized? I want to add the values to the labels.
# Solution
The label configuration of a pie chart is in the `label` field: https://visactor.io/vchart/option/pieChart#label. There is a property called `formatMethod` in this field, which is used to format the label content: https://visactor.io/vchart/option/pieChart#label.formatMethod. By configuring a function, the label can be formatted. The function receives parameters including the original text and data, and returns a string representing the formatted label text.
# Code Example
```TypeScript
const spec = {
type: 'pie',
data: [
{
id: 'id0',
values: [
{ type: 'oxygen', value: '46.60' },
{ type: 'silicon', value: '27.72' },
{ type: 'aluminum', value: '8.13' },
{ type: 'iron', value: '5' },
{ type: 'calcium', value: '3.63' },
{ type: 'sodium', value: '2.83' },
{ type: 'potassium', value: '2.59' },
{ type: 'others', value: '3.5' }
]
}
],
outerRadius: 0.8,
valueField: 'value',
categoryField: 'type',
title: {
visible: true,
text: 'Statistics of Surface Element Content'
},
legends: {
visible: true,
orient: 'left'
},
label: {
visible: true,
formatMethod: (text, datum) => {
return `${text}: ${datum.value}`
}
},
tooltip: {
mark: {
content: [
{
key: datum => datum['type'],
value: datum => datum['value'] + '%'
}
]
}
}
};
const vchart = new VChart(spec, { dom: CONTAINER_ID });
vchart.renderSync();
// Just for the convenience of console debugging, DO NOT COPY!
window['vchart'] = vchart;
```
# Result
After running the code, the labels can be formatted.

Over the past weeks I realised I have been using certain terms... | 27,627 | 2024-06-07T08:58:47 | https://dev.to/aizeon/similar-terms-used-in-cloud-computing-53a8 | beginners, cloud, cloudcomputing, terminologies | _Hello there. Time for a quick break._
Over the past weeks I realised I have been using certain terms in the wrong contexts and decided to make a post about this in case there are others in the same shoes.
## **PROVISIONING VS DEPLOYMENT**
### **PROVISIONING**
- process of setting up and configuring the necessary infrastructure and resources for a solution or application.
- includes creating virtual machines, storage accounts, databases, and other resources.
- involves installing and configuring software, services, and agents on the provisioned resources.
### **DEPLOYMENT**
- process of releasing and making a solution or application available for use.
- involves installing and configuring the solution or application on the provisioned resources.
- includes configuring networking, security, and other settings to make the solution or application accessible and usable.
In summary, provisioning is the process of setting up the necessary resources and infrastructure, while deployment is the process of releasing and making the solution or application available on those resources.
## **DATABASE VS STORAGE**
- Data structure: Storage focuses on unstructured data, while databases manage structured data.
- Data retrieval: Storage provides direct access to data, while databases enable querying and filtering.
- Data consistency: Databases enforce data consistency and transactions, while storage focuses on data durability.
- Scalability: Both storage and databases can scale, but databases require more complex scaling strategies.
## **AUTOMATION VS ORCHESTRATION**
Automation refers to the use of software or tools to execute repetitive tasks or processes without human intervention. It focuses on automating individual tasks or workflows.
Orchestration, on the other hand, refers to the coordination and management of multiple automated tasks or workflows across different systems, services, or applications. It focuses on managing the entire lifecycle of complex processes, ensuring that multiple tasks are executed in the correct order, and handling dependencies, errors, and rollbacks.
In other words, automation is about executing a specific task, while orchestration is about managing the entire process, including multiple tasks, dependencies, and workflows while automation is a key aspect of orchestration, orchestration is a broader concept that encompasses automation, coordination, and management of complex processes and workflows.

now we need to create folder inside the public with the name img then we will create our image that use hdri mode.
You can create your own image or you can find one from any resource in this part i basically use greater website called HDRi Haven then i convert the image to webp just to minify the total size of the image also in my case i don’t care about the shadow reflex and that other powerful things.
Now we have the image img/hdri.webp in our public folder we are ready to use our component in the index.vue page.
Note that: we may have some rendering problem if we use SSR with our app so basically we will use <ClientOnly> wen we call our component like bellow.
```
<ClientOnly>
<Landing/>
<template #fallback>
<!-- this will be rendered on server side -->
<p>Landing is loading...</p>
</template>
</ClientOnly>
```
**That’s it, we have now a basic 360 landing page**

1,880,143 | 10 Common Issues in Domain Management & Solutions | A domain name is a distinctive identifier for users to locate your website. This is why you should... | 0 | 2024-06-07T08:55:28 | https://dev.to/martinbaun/10-common-issues-in-domain-management-solutions-mjo | webdev, productivity, learning | A domain name is a distinctive identifier for users to locate your website.
This is why you should have one.
## Prelude
A domain is crucial to defining your internet persona. It impacts the credibility, usability, and branding of your website.
Owning a domain isn't enough to ensure a successful online identity. You can encounter various issues as a website owner, which calls for effective management of this domain. Read on as I explore ten issues and how to mitigate them.
## What is domain management?
Domain management is registering, configuring, and maintaining the use of a domain name. It may involve renewal, updates to pertinent contact details, and configuring DNS settings.
This undertaking is essential because if your domain expires, it can lose internet traffic and revenue. Managing your domain is vital in keeping out hackers and preventing unauthorized access to confidential data. It is useful in ensuring compliance with domain name management best practices and industry standards, like ICANN regulations.
## Common issues in domain management
## Lack of knowledge
Website owners may not fully understand all that goes into domain management. They may miss vital technical details in registering, renewing, or configuring their domains. This could negatively impact their website's performance and security. It can introduce a bevy of subdomain name registration issues.
### Solution:
>Site owners should invest in learning about the nitty-gritty of domain name management. There are several online resources and industry publications that they can utilize. Consult with experts in the field and keep tabs on updates in ICANN policies around the same.
## Missed renewals
If a company switches domain administrators without the proper handover, the new entrant could miss registration renewal notices for one or more domains. The credit card linked to the domain account may expire before the renewal date. A missed renewal could result in the domain name becoming unavailable through its acquisition by someone else. This could lead to lost traffic, brand damage, and a host of legal issues.
### Solution:
>Organizations should automatically renew all their domains to mitigate this. Credit on account rather than credit card payments would be prudent.
## Domain disputes
It is typical to find multiple parties claiming ownership of the same domain name. This could arise from the accidental registration of similar domain names or trademark disputes between organizations. Someone can buy a domain name in advance and hold the proper rights owner to ransom for the domain. This is called cybersquatting.
### Solution:
>Conduct proper research before registering your domain name to avoid trademark disputes. Register several names similar to your domain, such as common typos. This prevents competitors and cybercriminals from using similar. Seek legal counsel in case of dispute.
## Complexity and risk of domain name management
Managing several domain names hosted by different providers could introduce risk and complexity. More than one administrator overseeing the collection of domains complicates this management. Each administrator may employ diverse management practices. All admins have access to the company's sensitive data. This leaves the company's data vulnerable to a breach if they have weak security measures.
### Solution:
>Delegate domain management to a single enterprise-class administrator who puts security first. This can streamline the entire management process and offer consistent and reliable support. Invest in domain name management tools that can automate various aspects of managing domains and provide live alerts for any potential issues.
## Difficulties in domain name transfer and inadequate service support
Companies often need to transfer domain names after mergers and acquisitions. These transfers are often technical. Complex manual processes and insufficient support make them even more challenging. This could cause delays in the transfer process or even loss of the domain to a competitor.
### Solution:
>Employ a reputable and qualified administrator to tackle the domain transfers on your behalf. This admin should provide round-the-clock multi-channel support in case of any issues. Proactively plan for any potential domain transfers. This includes ensuring the domains are not locked for transfer or close to their expiry dates.
## Insufficient domain name security
Cybersecurity threats are ever-evolving, and protection measures should be regularly updated to combat domain name security issues. Insufficient security may lead to website downtime or data breaches.
### Solution:
>Employ corporate-focused registrars to keep out any security threats. Implement best practices for domain security, such as strong passwords and 2FA authentication. Use SSL certificates to encrypt your website traffic and prevent man-in-the-middle attacks.
## No domain name monitoring
Website owners or managers may fail to monitor their domains for potential threats or issues. This could expose their websites to security risks and damage their brand's image.
### Solution:
>Stay vigilant in domain security management. Regularly check for any changes to the domain name, expiry dates, or SSL certificate statuses. Look out for any online trademark infringements and cybersquatting. Utilize domain name monitoring tools that provide alerts of potential threats in real time.
## Spread across multiple registrars.
It is commonplace for large organizations to find their domain names spread across multiple administrators. This could result from mergers and acquisitions, some business units acting independently, or other reasons. Using multiple admins can introduce ambiguity around the business's total number of domains, the information linked to each, and the individuals authorized to access them. This exposes the corporation to a high-security risk.
### Solution:
>Have all your domains under a registrar's management that can support several registries and domains. This facilitates implementing domain management best practices, such as naming conventions and maintaining a central domain inventory.
## Accounting discrepancies and payment mishaps
The accounting side of domain management can prove quite challenging when a company owns several domains with different billing cycles and payment methods. This could result in some missed payments, leading to service disruptions from expired domains.
### Solution:
>Implement accounting practices for domain management. Select an enterprise-level registrar who offers reliable, transparent billing and alerts of upcoming payments. Regularly review and reconcile all domain-related accounting records to ensure accuracy and address any mishaps accordingly.
## Difficulty handling registry requirements from multiple regions
Different regions usually have varying regulations for registering domains bearing their country's extension. Each registrar may differ in the domain extensions they offer. Your regular registrar may not support the extension of the country you're interested in doing business. This introduces the issue of having your domains scattered across different administrators.
### Solution:
>Engage a corporate domain admin who is well-versed in regulatory requirements worldwide. They should also support the registration of domains from all over the globe and offer you expert advice on how to proceed.
## Benefits of effective domain management
- Ensures all relevant domain names remain under the control of your company or organization
- Prevents unauthorized access, hacking, or domain hijacking
- Simplifies the process of registering and managing domains in different countries
- Facilitates simpler domain name transfer
- Saves money by preventing losses emanating from missed renewals
- Enables companies to spot and take advantage of new domain name opportunities
-----
## Summary
A domain name is a vital part of your business's online identity. It is unique to your company. Owning a domain name does not create a successful online presence. Actively manage and monitor your domain to ensure it doesn't fall into unauthorized hands. We've discussed the top 10 issues that website owners face regarding domain management, as well as their solutions.
Domain management requires careful organization and maintenance for smooth operations and optimal performance. This is the same for Software Development.

1,877,633 | Thoughts on using ChatGPT in job interviews | A software developer friend told me yesterday that she had a job interview where she had to do live... | 0 | 2024-06-07T08:52:59 | https://dev.to/shaharke/thoughts-on-using-chatgpt-in-job-interviews-1ejo | interview, software, ai | A software developer friend told me yesterday that she had a job interview where she had to do live coding and was not allowed to use ChatGPT. She could search Google for what she needed, but not ask ChatGPT or similar tools. I'm not a big fan of live coding in the first place, but fine. But not using ChatGPT? Why? In my opinion, it's simply a lack of understanding of what the required skillset for developers is in the ~~future~~ present. To me, it's equivalent to asking in an interview to code in a text editor instead of an IDE. Let me explain.
A few days ago, a [new article](https://newsletter.pragmaticengineer.com/p/ai-coding-agents?publication_id=458709&post_id=145297550&isFreemail=true&r=1572ms&triedRedirect=true) was published in The Pragmatic Engineer where he talks about AI Software Agents. Software agents know how to use language models to solve software problems autonomously and almost without human intervention. In a recent experiment conducted by researchers at Princeton University, software agents were able to correctly solve 12.5% of the tickets given to them completely independently. That's crazy. And this is after just 6 months of work by a team of only 7 people. Imagine what a company like Cognition Labs (the company behind Devin.ai), which received $175 million in funding, will manage (or already has) to do in the same timeframe.
Note that I wrote that software agents worked "almost" without human intervention. It seems that at least for now*, there are two places where human involvement is required - (1) defining the problem and (2) reviewing the solution. It also appears to be an iterative process where (1) and (2) run in a loop until a good enough solution is reached. As of today, the people who have the most suitable skillset and knowledge to operate software agents are ...**drum roll**... developers.
How does all this relate to job interviews? Even if we work with Princeton's numbers, it effectively means that the rate of solving at least 12.5% of software companies' software problems can be accelerated by orders of magnitude. In other words, all other things being equal, a company that encourages its developers to use software agents has a significant advantage over a company that doesn't. And if that is indeed the case, then a company that does not test the ability of developers to actively use tools like ChatGPT is effectively missing a critical skillset for the company's success.
By allowing the use of ChatGPT, the screening process would simulate a more realistic development scenario. Candidates could engage the AI assistant as they would when actually working, using it as a knowledgeable resource and collaborator to help break down problems, propose solutions, and refine their code.
The true skills being evaluated then become the abilities to properly frame problems, ask the right questions, and critically analyze the information or code snippets provided by ChatGPT. These higher-level skills of problem decomposition, communication, and critical thinking are arguably more important than brute memorization of syntax and algorithms.
* I'm betting that even this will be replaced by AI agents in the near future, but that's for another post. Maybe.
## Potential objections
(Thanks to [David Shimon](https://x.com/davidshimon) for raising interesting objections)
### Objection #1:
> When we interview developers, we're not looking to test if they know how to use ChatGPT because that's relatively easy and we assume they'll be ok with it. On the other hand, using ChatGPT might mask other abilities that the candidate may be lacking. If we use the IDE analogy, in an interview it's not interesting to test if the candidate knows how to use an IDE as it is to see them write code.
I disagree with this objection on several levels:
First, using ChatGPT is easy. But using it **effectively** isn't. At least for now, developers need to make sure ChatGPT doesn't hallucinate too much, writes quality code, and one that's suited to the technologies used at the company. Crafting the right prompt and improving it iteratively is no easy task.
Like I said, observing a candidate use ChatGPT live can provide valuable insights into their thought process. I argue that incorporating ChatGPT into the interview presents a better opportunity to assess how a candidate approaches problems than a traditional coding exercise. The focus shifts away from merely testing technical coding proficiency towards evaluating problem-solving skills, code review abilities, and the iterative refinement of solutions. With a sufficiently complex exercise, the interviewer could dive into more advanced aspects of programming that are seldom explored when a candidate must write all the code from scratch.
Lastly, live coding is a rather stressful setting already and necessarily time-boxed. In such a session, we want to lower as many barriers as possible that would unnecessarily slow the candidate down without being related to their day-to-day work.
### Objection #2:
> Many companies already have tried-and-tested exercises for screening candidates, but using ChatGPT would make them too easy. Starting to modify exercises just to allow ChatGPT isn't worth the investment.
This argument is irrelevant for new companies or those seeking to update their existing coding exercises. In my experience, many companies don't stick to a single exercise for years; instead, they adapt it to align with rapidly evolving technology requirements. As for the remaining companies, if their exercise can be easily solved using ChatGPT, it may indicate that the exercise is evaluating the wrong skills. For instance, numerous companies today assess algorithmic knowledge through "LeetCode"-style problems, which are rarely applicable to the day-to-day tasks of 99% of programmers. While ChatGPT, assuming no hallucinations, can trivialize such algorithmic questions, one must question the value these questions provided in the first place.

Regardless of the programming languages and platforms, they all will encounter various designing requirements. For example, sometimes multiple trading varieties of rotation are required, sometimes multi-platform hedging is required, and sometimes different trading varieties are required to be concurrent. Let's share some of the designing experience when implementing the strategy writhing requirements.
The learning platform still uses the FMZ Quant trading platform (https://www.fmz.com), and the market is selected as the cryptocurrency market.
## Multi-cryptocurrency strategy design
Most of these demand situations are prepared for multi-cryptocurrency trend and grid strategies, which need to be executed on the market with different trading iteration methods.
Usually designed like this:
```
function Process (symbol) {
exchange.IO("currency", symbol)
var ticker = _C(exchange.GetTicker)
Log("has switched trading pairs, processing trading pairs according to strategy logic:", symbol, "quotes: ", ticker)
// ...
// ..
// .
}
function main(){
var symbols = ["BTC_USDT", "LTC_USDT", "ETH_USDT"]
while (true) {
for (var i = 0 ; i < symbols.length; i++) {
Process(symbols[i])
Sleep(500)
}
}
}
```
We configure the robot:
It can be seen that this realizes that an exchange object is configured on the robot, and the trading pair is switched; the market of different trading pairs is obtained, and the multi-trading variety market is executed; and it executed under a strategy logic.
It can be seen that the three trading pairs we define: BTC_USDT, LTC_USDT, ETH_USDT, in the loop, iteratively obtain the market quote, and after obtaining the information, it can specifically detect the market and trigger the trading logic designed by the strategy.
Some readers may ask: "I don't like to switch trading pairs, it feels a bit troublesome, and the strategy logic is not clear."
There are indeed other design options, which we will introducing it at below.
## Configuring multiple exchange objects for the robot in the same exchange account
The market data of different trading pairs is obtained through multiple exchange objects, and is executed in the iterative strategy logic.
For example, configure the robot by configuring three exchange objects for the robot. The trading pairs are set to BTC_USDT, LTC_USDT, and ETH_USDT respectively.
The name is the "OKEX Spot V3 Test" exchange object, on the Dashboard page, the exchange configuration page:
All done.
We changed a little bit of these code, because this time we added multiple exchange objects to the robot, which are the exchange objects of the trading pair BTC_USDT, LTC_USDT, ETH_USDT.
```
function Process (e) {
var ticker = _C(e.GetTicker)
Log("exchange", e.GetName(), "Process trading pairs according to strategy logic：", e.GetCurrency(), "Quotes：", ticker)
// ...
// ..
// .
}
function main(){
while (true) {
for (var i = 0 ; i < exchanges.length; i++) {
Process(exchanges[i])
Sleep(500)
}
}
}
```
Run the robot:
The example we described above, whether switching trading pairs or adding a trading object for multiple different trading pairs of a configuration account. All of these are just using an exchange account configuration (using a configured exchange).
So how do you use multiple exchange accounts in one strategy?
## Strategy for using multiple exchange accounts
Some strategies such as multi-exchange cross-market hedging, multiple-account strategies within a single exchange.
- Multiple exchanges configuration with different exchanges
For example, we have configured 2 exchanges on the Dashboard -> Exchange -> Adding Exchange page.
we can access to the asset information of the accounts configured by these two exchanges in the strategy.
```
function main(){
Log(exchanges[0].GetAccount()) // Print the account asset information of the first exchange object.
Log(exchanges[1].GetAccount()) // ... Print the asset information of the Bit-Z exchange
}
```
Of course, I can also add a second and third account exchange configuration to an exchange.
- Multiple exchanges configuration with the same exchange.
For example, we add another account for Huobi Futures.
As you can see, this configures the accounts of the two "Huobi Futures" exchanges.
When the strategy is created, a Huobi Futures Exchange object appears in the Robot's Modify Configuration option for selection.
For example, this allows two accounts to be selling first and then buying with typical grid strategy (up) or buying first then selling (down).
**Through the above two examples**
Here is the difference between configuring multiple exchange objects on the robot and "Configuring multiple exchange objects for the same exchange account for the robot":
This slamming and above-mentioned example of "The same exchange account has multiple exchange objects for the robot" is somewhat similar, but there are differences.
The difference is that the example above is an exchange configuration, ie:
When the robot configures the exchange object, it always uses:
This configuration.
It's just that when you add an exchange object, the trading pair settings are different.
If the GetAccount function is called, the asset information of the same account is always accessed.
however:
The two huobi futures exchange objects thus configured, although they are all huobi futures, represent different exchange accounts.
- The use of exchange configuration makes the design of cryptocurrency futures strategy easier.
Sometimes in the strategy of cryptocurrency contract hedging, in order to seize the fleeting trading opportunities, many scenarios need to be placed concurrently. However, because the contract is different, you need to switch to the corresponding contract when you get the market quote and place an order. When using the exchange.Go function to execute a placing order function or get the quote, there is a problem with synchronization, not very fast. And the design of the switch contract also makes the logic not so simple. Is there a better way?
Of course there are, We can add two exchange objects to the robot by following the "Configure multiple exchange objects for the robot in the same exchange account".
Then use this exchange configuration to add another exchange object.
A prompt box will pop up!
An exchange account configuration, you can not add exchange objects of the same currency or trading pair.
What should I do? It seems that the strategy robot can't use two exchange objects, and the exchange object is bound to an exchange account number?
There is still a way!
Let's go to the "Dashboard" -> "Exchange", and then add an OKEX futures exchange configuration.
Click Save when configured.
This way we have two exchange configurations, but the same API KEY configuration information is used.
What are the benefits of this?
When writing a strategy, the design will be very simple!
```
function main(){
exchanges[0].SetContractType("quarter") // Set the first added exchange object. The current contract is a quarterly contract.
exchanges[1].SetContractType("this_week") // Set the second added exchange object, the current contract is the current week contract
while (true) {
var beginTime = new Date().getTime() // Record the timestamp from which this time the market quote was taken.
var rA = exchanges[0].Go("GetTicker") // Create a concurrent thread to get the first exchange object, which is the market data for the quarterly contract.
var rB = exchanges[1].Go("GetTicker") // Create a concurrent thread to get the second exchange object, which is the market data for the weekly contract.
var tickerA = rA.wait() // The two threads executing each other perform their own tasks, waiting to get the data. When A waits, the B task is also executing.
var tickerB = rB.wait() // So it seems to be sequential execution, actually at the bottom of the concurrency. Only when you get the order is to get A first, and get B.
var endTime = new Date().getTime() // Record the timestamp at the end of the two contract quotes.
if (tickerA && tickerB) { // If there is no problem with the data obtained, execute the following logic.
var diff = tickerA.Last - tickerB.Last // calculate the difference
$.PlotLine("diff", diff) // Use the line drawing library to plot the difference on the chart.
if (diff > 500) { // If the spread is greater than 500, hedge arbitrage (of course, the difference of 500 is relatively large, rarely seen.)
// Hedging
rA = exchanges[0].Go("Sell", tickerA.Buy, 1) // Concurrent threads create a selling order under the quarterly contract
rB = exchanges[1].Go("Buy", tickerB.Sell, 1) // Concurrent thread create a buying order under the weekly contract
var idA = rA.wait() // Waiting for the return of placing order results, returning the order ID
var idB = rB.wait() // ...
}
// ...
}
LogStatus(_D(), "Concurrently get two contract quotes taking time:", endTime - beginTime, "millisecond.") // Shows the time on the status bar to know that the program is executing.
Sleep(500)
}
```
Is this design strategy much simpler and clearer?
Real market operation:
As you can see, it takes only about 50 milliseconds to get the price of two contracts each time.

## Understanding Tokenization
The act of turning an asset’s rights into a digital token on a blockchain is known as tokenization. It entails creating a blockchain token to stand in for an asset or a unit of value. Digital tokens are a substitute for actual tradeable assets.
These assets can be physical, like real estate or artwork, or digital, like a share in a company or a utility within a specific ecosystem. They offer:
- Ownership representation
- Decentralized participation
- Transaction facilitation
- Diverse asset representation

## ERC-20 (Ethereum Request for Comments 20) Standard
The Ethereum standard for fungible tokens is called ERC-20. Using this standard, developers may create tokens that represent assets, ownerships, rights, cryptocurrencies, and more, all with the use of smart contracts. Developers may design tokens that are identical to other tokens thanks to ERC-20.
**Characteristics**
Here are the characteristics of ERC-20 tokens:
- Fungibility: ERC-20 tokens exhibit fungibility and allow for seamless interchangeability. Each token of a specific type is indistinguishable from another, fostering uniformity in value.
- Divisibility: These tokens are divisible so that you can break them into smaller units. This feature enhances flexibility in transactions, accommodating fractional amounts.
- Interchangeability: It is a key feature that ensures that each ERC-20 token of a particular type is interchangeable with any other token of the same type. This facilitates smooth trading and usage across platforms.
- Standardization: ERC-20 tokens adhere to a standardized set of functions and events. This adherence ensures consistency and compatibility across various decentralized applications (dApps), wallets, and exchanges within the Ethereum ecosystem.
- Transparency: All token transactions and balances are visible on the public ledger so they operate with transparency.
**Use Cases**
ERC-20 tokens offer multiple use cases that make them a popular choice for a wide range of applications within the blockchain ecosystem:
- ICO (Initial Coin Offering) Crowdfunding: ERC-20 tokens are widely used for ICOs. They allow projects to raise funds by issuing and distributing their native tokens to investors.
- Tokenized Assets: You can tokenize real-world assets, such as real estate or art, using ERC-20 standards. This enables fractional ownership and increased liquidity.
- Decentralized Exchanges (DEX): Many DEXs utilize ERC-20 tokens for trading pairs. The standardization ensures compatibility across various platforms.
- Utility Tokens: Projects create utility tokens on the ERC-20 standard. These tokens provide access to specific features or services within their platforms.
## BRC-20 (Bitcoin Request for Comment 20)
The BRC-20 token standard, designed for the Bitcoin blockchain, is an experimental fungible token standard facilitating the development and transfer of tokens through the ordinals protocol. Unlike ERC-20, BRC-20 doesn’t rely on smart contracts. Instead, it utilizes ordinal inscriptions.
Bitcoin ordinal inscriptions, introduced on Jan 21, 2023, by Casey Rodarmor, enable users to inscribe data, like JSON code, onto satoshi tokens. They provide a different strategy from ERC-20’s dependence on smart contracts.
**Characteristics**
Here are the characteristics of BRC-20 tokens:
- Fungibility: Just like ERC-20, BRC-20 tokens excel in fungibility. Each token within a specific type holds identical values and functions. This ensures seamless interchangeability and simplified transactions.
- Divisibility: Similar to ERC-20, BRC-20 tokens have divisibility functionality that allows them to be split into smaller units. This facilitates micro-transactions and fractional ownership.
- Non-Standard Interface: This is where BRC-20 stands out. Unlike ERC-20’s standardized functions, BRC-20 embraces flexibility. Developers can tailor token functionalities to create unique features beyond the basic set.
- Bitcoin Integration: BRC-20 tokens leverage the Bitcoin network’s robust security and established user base. This integration offers the potential for wider adoption and familiarity compared to solely Ethereum-based tokens.
**Use Cases**
BRC-20 tokens offer the following use cases:
- Peer-to-Peer (P2P) Transfers: Users can seamlessly move BRC-20 tokens across different wallets without intermediaries. BRC-20 tokens enhance efficiency by aligning with Bitcoin’s transaction model, where fees are naturally charged in Bitcoin.
- DeFi (Decentralized Finance): BRC-20 tokens offer flexibility and seamless integration with DeFi protocols. These tokens are opening new possibilities for decentralized financial platforms like decentralized exchanges (DEX), yield farms, and lending protocols.
## Key Differences between ERC-20 and BRC-20 Tokens
Here are the key differences between ERC-20 and BRC-20 tokens:
**Blockchain Standards and Development**
BRC-20 and ERC-20 represent distinct token standards on separate blockchains. BRC-20 operates on the Bitcoin blockchain, while ERC-20 is native to the Ethereum blockchain.
ERC-20 and BRC-20 tokens differ significantly when it comes to their development. Developers create ERC-20 tokens using smart contracts on Ethereum.
On the other hand, BRC-20 takes a non-standard approach, utilizing Bitcoin’s existing UTXO model. Instead of building a smart contract, token information is embedded directly into satoshis, the smallest units of Bitcoin.
**Operation**
ERC-20 tokens operate seamlessly within Ethereum. Every transaction involving these tokens follows the established ERC-20 protocol. This ensures compatibility with Ethereum wallets, exchanges, and dApps.
BRC-20 tokens take a more independent approach with parallel operation. BRC-20 transactions are validated separately from Bitcoin transactions, using a dedicated set of rules encoded within the inscribed JSON files. This creates a distinct layer of operation on top of the Bitcoin network.
**Integration**
The integration capability of BRC-20 tokens holds a distinct advantage over ERC-20 tokens, particularly in streamlining remittance processes. BRC-20 tokens can utilize the Lightning Network (LN) and provide an efficient remittance solution without compromising network security.
In contrast, while ERC-20 standards are designed for composability with other blockchains, this flexibility comes at a security cost. BRC-20 tokens, prioritizing security, avoid such compromises. This makes them a more secure option compared to ERC-20 tokens.
**Flexibility**
ERC-20 stands out for its inherent flexibility, granting businesses the ability to tailor tokens to specific use cases on Ethereum. This adaptability ensures precision in functionality and opens doors to a myriad of possibilities.
On the other hand, BRC-20 tokens, rooted in the Bitcoin blockchain, initially present challenges in supporting a wide range of use cases. The ecosystem may find its strength in a focused approach, catering to specific sectors.
**Transaction Speed**
Transaction speed is predominantly determined by the processing efficiency of transactions. On the Ethereum blockchain, transaction speed is influenced by the Maximal Extractable Value (MEV) concept. In Ethereum, users can offer higher gas fees to receive preferential treatment.
In contrast, Bitcoin employs a different approach, writing data on blocks and relying on miners to validate them. Unlike the Ethereum blockchain, Bitcoin’s transaction processing is not influenced by the ability to pay higher fees.
## Choosing the Right Token Standard
While ERC-20 tokens offer flexibility and integration within the Ethereum ecosystem, BRC-20 tokens bring security and potential speed advantages to the Bitcoin blockchain.
You need to carefully consider your priorities, such as integration, security, flexibility, transaction speed, and community adoption, to guide your decision. Understanding these nuances helps you select the token standard that aligns with your vision. It can unlock the full potential of your digital assets and pave the way for success in the ever-evolving blockchain world.

As a React developer, I've found several libraries indispensable for creating efficient and visually appealing applications. Here's a rundown of the libraries I frequently use and recommend:
**_UI Library:_**
Mantine UI: In 2024, Mantine UI has become my go-to choice for a comprehensive UI library. It stands out due to its unique and highly practical components that are ready to use out of the box. This library eliminates the need to design components from scratch, allowing developers to focus more on functionality. Mantine also offers its own hooks for form state management, which is incredibly convenient. For handling complex tables, I rely on mantine-react-table. I highly recommend trying Mantine UI in your projects and sharing your experience.
**_State Management (Global and Server-Side):_**
For global state management, I use a combination of react-hooks with react-context and react-reducer hooks. For smaller state management tasks, I sometimes incorporate react-stateful hooks.
For server-side data fetching, react-query is my preferred choice. It efficiently handles data fetching and mutations, making server-side state management straightforward. I also use axios for making HTTP requests, which pairs well with react-query.
**_Charts:_**
While Mantine provides some minimal charting capabilities, for more complex charting needs, I turn to nivo charts. Nivo offers a rich set of features for creating beautiful and interactive charts.
PDF Generation:
**_For generating PDFs_**
react-to-pdf is my tool of choice. It simplifies the process of converting React components into PDF documents, making it a valuable addition to my development toolkit.
These libraries have proven to be incredibly valuable in my development workflow, enhancing productivity and the overall quality of the applications I build. I encourage you to explore these tools and see how they can benefit your projects. | rajivchaulagain |

1,880,129 | How to display all words in a small canvas using vchart word cloud? | Title How to display all words in a small canvas using vchart word cloud? ... | 0 | 2024-06-07T08:47:44 | https://dev.to/neuqzxy/how-to-display-all-words-in-a-small-canvas-using-vchart-word-cloud-1ki9 | # Title
How to display all words in a small canvas using vchart word cloud?
# Description
When the number of words in vchart word cloud is large and the canvas size is not large enough, only a part of the words can be displayed. How can we display all the words?
# Solution
The word cloud has a configuration `fontSizeRange` that controls the size range of words. The default value is `[20, 40]`. If you want the text to automatically adapt to the canvas size and fill the entire canvas, you can set it to `auto`.
Reference: [VisActor](https://visactor.io/vchart/option/wordCloudChart#fontWeightRange)

"Bringing Nature Indoors: The Essence of Biophilic Design"
Biophilic design is an innovative approach in the architectural and interior design fields that strives to bring building occupants closer to nature. It utilizes natural elements for increased well-being, health, and productivity in the built environment. Here are key principles and elements of biophilic design:
Key Principles of Biophilic Design
Direct Nature Contact:
Natural Light: Introduction of natural light through the use of windows, skylights, and light wells
Views of Nature: The provision of views of natural landscapes, water bodies, or green spaces
Water Features: The inclusions of water elements: fountains, aquariums, or ponds
Vegetation: the use of plants, green walls, and indoor gardens
Indirect Nature Contact:
Natural Materials: The use of wood, stone, bamboo, and other natural materials in construction and decor
Natural Patterns and Forms: Spaces mimic shapes and patterns occurring in nature, such as fractals or leaf motifs
Natural Colors: A palette derived from natural landscapes: greens, blues, and earthy tones
Spatial Configurations:
Prospect and Refuge: The combination of openness (prospect) with a sense of protection and enclosure (refuge)
Complexity and Order: Environments that balance the presence of overwhelming richness with order, similar to natural ecosystems
Biomorphic Forms: shapes and forms that are akin to natural organisms and ecosystems
Biophilic Design Benefits
Well-being:
Being exposed to natural elements can have a reducing effect on stress, lower blood pressure, and improve mood
When spaces incorporate biophilic design principles, they are often more calming and restorative
Productivity:
Natural light and views are known to boost focus and creativity and even increase productivity in a workplace
Incorporating natural elements can reduce absenteeism and increase job satisfaction
Health:
Access to natural light and ventilation can reduce the incidence of illnesses and improve respiratory health
There have been indoor plants that can improve air quality by lessening pollutants and increasing humidity
Sustainable Design:
Biophilic design is often integrated with sustainable design practices to improve energy efficiency and promote the use of renewable resources
Now, Biophilic Design Examples
Amazon Spheres, Seattle:
These spaces are designed to simulate greenhouses with over 40000 plants from 400 different species across the globe. It is a natural and lavish space for the employees of Amazon that evokes their creativity and a sense of relaxation.
Changi Airport, Singapore
The Changi airport has a lot of indoor gardens, waterfalls, and natural light created for being a soothing and refreshing experience for travellers.
Pasona Urban Farm, Tokyo
The entire office building is designed to have the components of urban farming, where employees work in an agricultural field in their daily work environment. The design is conducive to the well-being and the sustainability of the individuals working in such an environment.
How to Put Biophilic Design
Assessment and Planning
Assess the existing space and look for spaces to incorporate biophilic design components.
Interact with stakeholders to understand their needs and desires.
Design and Integration
#Aritecture #Architecture and Interior Design #Design
Co-operation with architects, interior designers and landscape designers who will help include these natural elements seamlessly.
Technology that will help to mimic natural light, control ventilation and maintain indoor plants
Maintenance and Adaptation
Regular maintenance and upkeep of the plants, water features and other natural elements.
Constant adaptation and updating of the space and its components based on the feedback of the users and changing needs
Biophilic design is a holistic approach that, along with improving the aesthetic appeal of the spaces, increases the quality of life of its users. It is a step towards more human-centric and sustainable design.

Web development, man, it's like it's on some kind of fast-forward button! New stuff pops up all the time, saying it'll make our lives easier and work smoother. But here's the thing: there's a big difference between hopping on the latest bandwagon and really knowing your stuff when it comes to the tech that makes the internet tick. So, let me tell you a story about this developer buddy of mine, John. His career had some serious ups and downs because of this whole framework deal.
John, he started out hot. Straight out of college, he scored a sweet gig at a big tech place. He knew this one framework like the back of his hand, and he was whipping out killer web apps like nobody's business. Dude was on fire, and he knew it.
But time goes by, and tech changes faster than fashion trends. Those new frameworks come along, and suddenly the one John was all about isn't the cool kid anymore. The thing is, these new toys need you to get down with the nitty-gritty – HTML, CSS, JavaScript, PHP – all the stuff that's like the internet's building blocks. And John? He never really got that deep into it.
So now, the company's got these young bucks coming in, and they're like sponges with these new frameworks because they actually get the core stuff. John's stuck trying to keep up, and let's just say it's not pretty. His mojo's gone because he's trying to use tools he doesn't really understand.
Fast forward to now, and John's still there, but he's not the big shot anymore. His workmates respect his OG status, but they feel bad because he's stuck in the slow lane of tech. And it's all because he didn't wanna learn the boring stuff everyone thought was old news.
So if you're in the game or looking to hire someone, take a page out of John's book, but learn from his mistakes. You wanna be the developer that's versatile, not the one who's left in the dust. Frameworks are cool, like the latest gadgets, but if you don't get the basics, you're gonna struggle when the next big thing hits.
I've seen it with job seekers, too. They come in all flashy with their framework skills, but when it comes to the real McCoy – the stuff that actually makes the internet work – they're lost. The ones who get it, who can ride the wave of change because they know their HTML from their elbow, they're the ones that shine.
So the moral of the story? If you're starting out in web dev or you're the boss man looking for fresh talent, remember John. Spend some quality time with the core tech – HTML, CSS, JavaScript, PHP – it's like your bread and butter. That way, you'll always be ready for whatever the tech world throws at you.
And don't be John, you know? Get those basics down pat, and you'll be set for life. Frameworks are fun, but they're like fads. Knowledge of the core stuff? That's your golden ticket, buddy. It's what keeps you ahead of the game, no matter what. | longblade |
1,880,019 | If, Else, Else If, and Switch JavaScript Conditional Statement | In our everyday lives, we always make decisions depending on circumstances. Chew over a daily task,... | 0 | 2024-06-07T08:30:59 | https://dev.to/odhiambo_ouko/if-else-else-if-and-switch-javascript-conditional-statement-39mo | webdev, javascript, development, beginners | In our everyday lives, we always make decisions depending on circumstances. Chew over a daily task, such as making coffee in the morning. If we have coffee beans, we can make coffee; otherwise, we won’t.
In programming, we may need our code to run depending on certain conditions. For instance, you may want your program to assign an A grade to students if they score more than 80 points or program a website to display a checkout tab on a liquor website only if the user is 18 or older. That's where conditional JavaScript statements come in. The conditions specify the code block to be executed if a specified condition is true.
Let's explore if, if…else, else if, and switch statements to understand how they are used in JavaScript.
##If Statement
The *if* statement is the most basic conditional statement in JavaScript. This statement evaluates a condition and executes the code block within its body if the condition is true. If the condition is evaluated as false, then the code block will not run.
If Statement Syntax
```JavaScript
if (condition) {
//code block to be executed if the condition is true
}
```
###If Statement in Action
We can use the *if* statement to execute a given code block provided a given condition is true. For example, we can write our code to send interviewees a congratulations message if they score 75 points or more.
```JavaScript
if (score => 75){
console.log(Congratulations! You’re hired)
}
```
Output
```
Congratulations! You’re hired
```
##If…Else Statement
What if we want to run a second code if the preset condition returns a false value? In that case, we employ the *if…else statement*. This statement checks a condition and runs the first code block if the condition evaluates to true. If the condition is false, the second code will execute instead.
If…Else Statement Syntax
```JavaScript
if (condition) {
//first code block to be executed if the condition is true
} else {
//second code block to be executed if the condition is false
}
```
###If…Else Statement in Action
We can instruct our program to let users aged 24 and above create a customer account but encourage those below 24 to try the process later.
```JavaScript
if (user => 24) {
console.log(Welcome! Proceed to open an account)
} else {
console.log(Age limit not reached. Try again in a few months!)
}
```
###Ternary Operator
Although *if…else* statements are easy to write, there is a shorter way to write them. The shorthand Is known as a ternary or conditional operator.
###Ternary Operator Syntax
```JavaScript
Condition? Expression 1 : Expression 2;
```
The example above represents the syntax of a basic ternary operator. The condition to be evaluated is put before the question mark *?*, followed by the statements to be executed. A colon *:* separates the two expressions. The entire operator ends with a semicolon. In the ternary operator, the first statement will execute if the condition is true. If it's false, the second expression will run.
###Ternary Operator in Action
```JavaScript
(passMark => 50)? console.log(Pass! Go to the next level) : console.log(Fail! Try again later);
```
In the above example, the program will print **Pass! Go to the next level** if the score is 50 or more. It will print **Fail! Try again later** if the score is below 50.
##Else If Statement
We usually use the if…else statement when evaluating one condition. What if we want to add more conditions to our if…else statement? Simple, we use the *else if* statement! Unlike the if…else statement, the else if statement allows us to have more than two possible outcomes. We can also use it as many times as we want.
###Else If Statement Syntax
```JavaScript
else if (condition) {
//Code block to be executed
}
```
###Else If in Action
```JavaScript
Let time = ‘12:00 am’
If (time === '9:00 am') {
Console.log(‘Good Morning! Time to wake up.’)
} else if (time === ‘12:00 am’) {
Console.log(‘Good afternoon! Time for lunch.’)
} else if (time === ‘4:00 am’) {
Console.log(‘Good Afternoon! Time to go to the gym.’)
} else if (time === ‘10:00 pm’) {
Console.log(‘Goodnight! Time to sleep.’)
} else {
Console.log(‘Invalid time!’)
}
```
In the above example, the program will print **Good afternoon! Time for lunch.** because the time is set to 12:00 am.
##Switch Statement
While the else if statements are incredible for introducing more conditions to our if…else statement, writing many statements can be cumbersome. Moreover, numerous else if statements chained in an if…else statement can be hard to evaluate. As a result, they often have readability issues and are notorious for causing errors.
Luckily, we can take advantage of the *switch statement* to avoid dealing with multiple if…else and else if statements. A switch statement is not only straightforward to write but also easy to read and maintain.
###Switch Statement Syntax
```JavaScript
switch(expression) {
case a:
//code block to be executed
break;
case b:
//code block to be executed
break;
case c:
//code block to be executed
break;
default:
//code block to be executed
}
```
The example above shows a switch statement. A switch statement begins with a variable called a switch followed by an expression enclosed in parenthesis. Curly brackets encircling case clauses come after the expression. Each case clause ends with a semicolon to tell the JavaScript interpreter to skip to the subsequent clause.
The switch statement evaluates the expression once and compares its value against those in the case clauses. Only the code block in the case clause that matches the expression will be executed. If there is no match, the default code will run.
###Switch Statement in Action
```JavaScript
let shoeName = ‘adidasSamba’
switch (shoeName) {
case ‘adidasGazelle’:
console.log(‘Adidas Gazelle costs $49);
break;
case 'adidaSamba':
console.log(‘Adidas Samba costs $99’);
break;
case 'adidasSuperstar'
console.log(‘Adidas Superstar costs $149)
break;
case 'adidasNMD'
console.log(‘Adidas NMD costs $199)
break;
case 'adidasCampus'
console.log(‘Adidas Campus costs $249)
break;
default:
console.log(Invalid option!);
break;
}
```
###Output
```JavaScript
Adidas Samba costs $99
```
##Parting Shot
Throughout this article, we’ve discussed JavaScript if, else, else if, and switch statements. These statements are essential when it comes to executing specific code blocks based on preset conditions. Each of the statements plays a distinctive role and must be used correctly to achieve the desired results. In conclusion, applying best practices and avoiding common pitfalls when using these conditions to unlock their full potential is imperative.

1,880,116 | Microsoft Azure Fundamentals. Core Architectural Components of Azure | Microsoft Azure, most times called Azure is a cloud computing platform developed by Microsoft. It has... | 0 | 2024-06-07T08:29:50 | https://dev.to/wisegeorge1/microsoft-azure-fundamentals-core-architectural-components-of-azure-8l3 | devops, aws, learning, database | Microsoft Azure, most times called Azure is a cloud computing platform developed by Microsoft. It has a wide range of capabilities, including software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). Just like other cloud computing platforms Microsoft Azure supports a wide range of services including computing, analytics, storage, and networking.
This discourse focuses on the core architectural components of Microsoft Azure to unravel the potential resource capabilities inherent in cloud computing.
**Regions**
The physical architecture of Azure starts with its various datacentres called regions. These regions are in different geographical locations scattered across the world, currently its datacentres are over sixty. These regions(datacentres) are structured in such a way that it allows for customers to deploy services closer to their users for improved performance and compliance, examples of these regions include East USA, West Europe, Southeast Asia etc.
Azure regions are some cases 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.
**Availability Zones**
The regions are in turn made up of physically separate locations known as availability zones, created to distribute resources across multiple zones to ensure high availability and resilience as each of the zones have its own independent power source, network, and cooling.
The design of the availability zones is to help protect applications and data from datacentre failures and to ensure high availability through redundancy. It must be noted that each region contains a minimum of three separate availability zones to ensure resiliency.
**Resource Groups**
As we go further into the architecture of Azure, we discover that it also has a logical container which houses all the resources for a predefined project, this container is referred to as Resource Groups. The resource groups make it easier to manage costs as it presents a simplified way of resource management and deployment since group resources can be arranged according to application, environment, or department. for example, a resource group for a web application could include the application service, database, and storage accounts. Also of note is the fact that resources within a defined group in Azure share the same lifecycle and management.
**Azure Subscriptions**
In Azure, a unit of management, billing, and scale is considered to be a subscription just the same way resource groups are a way to logically organize resources, subscriptions allow you to logically organize your resource groups and facilitate billing. In order to use Azure you are require to own a subscription. A subscription lets you have authenticated and authorized access to Azure products and services. It also allows you to provision resources. An Azure subscription links to an Azure account. An account can have multiple subscriptions, but it is only required to have one.
**Azure Resource Manager**
Lastly in the Azure architecture framework is the Azure Resource Manager (ARM). This is the part that is responsible for the deployment and management of service for Azure. In other words, resources are managed and organized in Resource Groups through ARM. Some of its key features include role-based access control (RBAC), tagging for resource organization, audit logs for tracking changes.
Because of its place in the Azure structure, we discover that ARM provides a unified way to manage Azure resources, it allows users to create, update, and delete resources as a group and it also uses templates to automate deployment of resources as a result helps to deliver the following benefits 1. provides a consistent management layer two. facilitates automation and orchestration of resources.
In conclusion, Azure supports a wide range of services that ensures high availability, scalability, and efficient resource management like programming languages, third party software and systems, tools, and frameworks including Microsoft specific software and tools.

1,880,108 | Deploying NestJS Apps to Heroku: A Comprehensive Guide | Deploying a NestJS application to Heroku can be a straightforward process if you follow the right... | 0 | 2024-06-07T08:26:35 | https://dev.to/ezilemdodana/deploying-nestjs-apps-to-heroku-a-comprehensive-guide-hhj | heroku, nestjs, typescript, backend | Deploying a NestJS application to Heroku can be a straightforward process if you follow the right steps. In this guide, we'll walk you through the entire process, from setting up your NestJS application to deploying it on Heroku and handling any dependencies or configurations.
**Step 1: Setting Up Your NestJS Application**
Before deploying, ensure you have a NestJS application ready. If you don't have one, you can create a new NestJS project using the Nest CLI.
**1. Install Nest CLI:**
```
npm install -g @nestjs/cli
```
**2. Create a New Project:**
```
nest new my-nestjs-app
cd my-nestjs-app
```
**3. Run the Application Locally:**
```
npm run start:dev
```
**Step 2: Prepare Your Application for Heroku**
Heroku requires a few specific configurations to properly deploy a Node.js application.
Let's go through these configurations step by step.
**1. Create a Procfile:**
In the root of your project, create a file named Procfile and add the following line:
```
web: npm run start:prod
```
This tells Heroku to start your application using the production build.
**NB:** The name of the file should be Procfile, nothing more nothing less, if the case is different from this, heroku won't recognize the file.
**2.Update package.json:**
Ensure your package.json has the following scripts:
```
"scripts": {
"start": "nest start",
"start:dev": "nest start --watch",
"start:prod": "node dist/main.js",
"build": "nest build"
}
```
Additionally, add the following configuration to ensure your app runs on the correct port:
```
"engines": {
"node": ">=14.0.0"
}
```
Depending on the node version you are using for your application.
**Step 3: Initialize a Git Repository**
Heroku uses Git for deployments. Initialize a Git repository if you don't have one already.
**1.Initialize Git:**
```
git init
git add .
git commit -m "Initial commit"
```
**Step 4: Deploy to Heroku**
Now, let's deploy your application to Heroku.
**1. Login to Heroku:**
Let's use the Heroku CLI to login, run the command on your project directory.
```
heroku login
```
This command will open a browser and require your login credentials, populate and complete 2FA, if enabled. The come back to the CLI.
**2. Create a New Heroku Application:**
```
heroku create my-nestjs-app
```
**3. Deploy Your Application:**
```
git push heroku master
```
**Step 5: Handle Environment Variables**
Heroku allows you to manage environment variables through its dashboard or CLI, let's manage a few via the CLI.
**1. Set Environment Variables:**
```
heroku config:set NODE_ENV=production
```
If you have other environment variables, set them as well:
```
heroku config:set DATABASE_URL=your_database_url
```
**Step 6: Verify Your Deployment**
**1. Open Your Application:**
```
heroku open
```
You can open the application from the Heroku dashboard as well.
**2. Check Logs:**
If you encounter any issues, check the logs with:
```
heroku logs --tail
```
**Conclusion**
Deploying a NestJS application to Heroku is a straightforward process if you follow these steps. By preparing your application properly and using Heroku's powerful features, you can have your NestJS app running in the cloud in no time. Whether you're deploying a simple API or a complex application with multiple dependencies, Heroku provides a robust platform for managing your applications. Happy coding!
**My way is not the only way!**

Hello everyone, السلام عليكم و رحمة الله و بركاته
## Introduction
Typing is essential for any language to ensure a friendly user experience. TypeScript is a statically typed language built on top of JavaScript, enhancing its syntax and providing powerful tools for extracting needed data from any request. This article will discuss:
- Types in TypeScript
- Interfaces
- Enums
- Operators like union and intersection
- Generics and how to make components reusable using generics
## Types in TypeScript
In TypeScript, types can be categorized into primitive types and complex types:
### Primitive Types
Primitive types include:
- **number**: Includes integers, floats, and decimals
- **bigint**: Represents whole numbers larger than 2^53 - 1
- **string**: Represents text data
- **boolean**: Represents true or false values
### Complex Types
Complex types include:
- **arrays**: Collections of elements
- **objects**: Collections of key-value pairs
- **enums**: Named constants
- **tuples**: Arrays with a fixed number of elements of specified types
- **never**: Represents values that never occur
- **void**: Represents the absence of a value, commonly used as the return type of functions that do not return a value
- **null**: Represents a null value
- **undefined**: Represents an undefined value
- **any**: Represents any type, opting out of type checking
## Interfaces
Interfaces in TypeScript define the structure of an object. They are used to describe the shape that an object should have, making it easier to ensure that objects conform to certain criteria.
### Example:
```typescript
interface User {
id: number;
name: string;
email?: string; // optional property
}
let user: User = {
id: 1,
name: "Bilel"
};
```
### Interfaces vs. Types
Both `interface` and `type` can be used to define the shape of an object, but there are some differences:
- `interface` can be extended, making it easy to add new properties or methods.
- `type` can represent a wider range of types (not just object shapes), including unions and intersections.
### Example of extending an interface:
```typescript
interface Animal {
name: string;
}
interface Bird extends Animal {
fly: string;
}
```
## Enums
Enums allow you to define a set of named constants, making it easier to manage sets of related values.
### Example:
```typescript
enum Direction {
Up,
Down,
Left,
Right
}
let move: Direction = Direction.Up;
```
### Enums vs. Union Types
- **Enums**: Provide a clear, self-documenting way to define sets of related constants.
- **Union Types**: Can be used to achieve similar functionality with more flexibility.
### Example of Union Type:
```typescript
type Direction = "Up" | "Down" | "Left" | "Right";
let move: Direction = "Up";
```
## Operators: Union and Intersection
### Union Types
Union types allow a variable to be one of several types.
### Example:
```typescript
let value: number | string;
value = 22; // valid
value = "Hello"; // also valid
```
### Intersection Types
Intersection types combine multiple types into one, ensuring that the resulting type has all the properties of the combined types.
### Example:
```typescript
interface Name {
firstName: string;
lastName: string;
}
interface Contact {
email: string;
phone: string;
}
type Person = Name & Contact;
let person: Person = {
firstName: "Bilel",
lastName: "Salem",
email: "bilelsalemdev@gmail.com",
phone: "22222222"
};
```
## Generics
Generics enable you to create reusable components that can work with any type. They provide a way to write functions, classes, or interfaces that can operate with different data types while retaining type safety.
### Example:
```typescript
function identity<T>(arg: T): T {
return arg;
}
let output1 = identity<string>("Hello");
let output2 = identity<number>(22);
```
### Reusable Components with Generics
Generics are particularly useful for creating reusable and flexible components.
### Example:
```typescript
interface Box<T> {
content: T;
}
let stringBox: Box<string> = { content: "Hello" };
let numberBox: Box<number> = { content: 22 };
```
## Conclusion
TypeScript enhances JavaScript by adding static types, making the code more flexible and powerful. By understanding and utilizing types, interfaces, enums, operators like union and intersection, and generics, you can write more predictable and reusable code. | bilelsalemdev |
1,880,107 | 6 Effective Ways to Boost Your Email Delivery Rate | Do you want to learn how to improve your email deliverability rate? If so, you're in the right place!... | 0 | 2024-06-07T08:22:29 | https://dev.to/syedbalkhi/6-effective-ways-to-boost-your-email-delivery-rate-37k3 | email, beginners, startup, wordpress | Do you want to learn how to improve your email deliverability rate? If so, you're in the right place! Email deliverability is an important metric for any email marketing campaign.
Put plainly, this metric will show you how many of your marketing emails are delivered versus how many you send. Ideally, you want as many people as possible to receive your emails because that means more opportunities to connect with your audience. For context, nearly [16%](https://www.wpbeginner.com/research/marketing-statistics-trends-and-facts-updated/#lead-generation-statistics) of all emails sent are not delivered for one reason or another.
In this post, I'll share 6 tips for increasing your email deliverability rate so you can get more emails to subscribers' inboxes.
Let's get started!
### Do Not Purchase Email Lists
The first thing you should do is never purchase email lists. This might look like an easy and fast way to increase your coverage, but the effects of this action are not worth it.
By sending unsolicited emails to unsuspecting individuals, you will end up with many people marking your emails as spam. When you get enough spam complaints from your subscribers, this will damage your sender reputation, which will make it harder and harder for your email to land in any recipient's inbox, not only the ones who marked you as spam.
So, instead of taking this unethical shortcut, you should concentrate your efforts on building an organic email list. Offer valuable content, like blog posts, to your target audience so you can make sure that the people who subscribe to your list are really interested in your brand and business.
I'd argue this will always result in a higher email deliverability rate and more engaged subscribers when compared to buying an email list.
### Use Double Opt-Ins to Confirm Interest
[Double opt-ins](https://funnelkit.com/optin-page-guide/) can help you increase your email deliverability and engage your audience. This method involves a two-step verification process that subscribers must take to join your email list. Usually, this verification process involves clicking a link in your welcome email.
Since new subscribers have to prove that they are genuinely interested in your brand by confirming their subscription, you can ensure that your email list is full of interested and potential customers.
We found that this step decreases [spam complaints](https://wpmailsmtp.com/wordpress-emails-going-to-spam/), increases engagement, and improves overall sender reputation, all of which lead to a higher email deliverability rate.
### Establish Expectations and Keep Your Promises
From the moment a user joins your email list, you should keep in mind that they showed interest in a particular offer that you most likely presented in the form of a lead magnet or coupon. So, the first email that you send to these new subscribers should start with this offer, and you should fulfill the interest that you sparked in them in order to make sure that they will not unsubscribe in the future or stop reading your emails.
The next step you should take is to clearly tell your subscribers what kind of content you will send them in the future. For instance, send an email to your new subscribers telling them that every month, you will send a digest with relevant posts from your blog and also ask them for suggestions related to what topics they are more interested in.
By setting expectations and doing what you said you would do, you will show your subscribers that you are committed to sending them personalized and relevant content. Want to know how this can help you? Consider this: [80%](https://www.pushengage.com/digital-marketing-stats-and-trends-2021/) of shoppers say they're more likely to engage with brands if they share relevant content and promotions.
### Test Your Emails
A great way to make sure that your emails look great and work as intended is to test them. This step will increase your chances of getting your emails read by subscribers because your content will look great across all devices, including laptops, smartphones, and tablets.
You should keep in mind that around [70%](https://smashballoon.com/social-media-marketing-statistics/) of people own a mobile device, and the majority of them use their phones to check for new emails. So, if your email is not properly displayed or functions poorly on these devices, your subscribers will most likely not come back to it later from a desktop computer.
So, to avoid this situation, you should get in the habit of testing your emails before sending them. Send a test email to yourself and members of your marketing team using different devices, simulate smartphone rendering using browser extensions or similar tools, or use professional testing services that will optimize your emails for multiple platforms.
Consistent testing can really increase your return on investment -- for us, it resulted in an average [28%](https://www.seedprod.com/verified-digital-marketing-statistics-and-trends/#Content-Marketing-Statistics) increase in our campaigns!
### Let Your Subscribers Manage Their Preferences
Letting your subscribers manage their email preferences is another sure way to make them happy and engaged. We all like to surround ourselves with people and businesses that allow two-way conversations, so your subscribers want to have a say in the kind of emails they get from you and their frequency.
You should ask your new subscribers about their preferences during the subscription process, but don't stop there. In each email you send, you should include a section where subscribers can easily manage their preferences whenever they want. If a subscriber is getting too many emails from you, they can simply change the frequency and not unsubscribe from all of your email lists.
By giving them this ease and freedom, you will retain subscribers who will still open your emails and engage with your business, which is a key element in maintaining a high email deliverability rate.
### Scrub Your List
No matter how much effort you put into your business, there will always be subscribers who become inactive and stop opening your emails. After a targeted campaign to re-engage them, if there is no change, you should consider removing inactive subscribers from your list---a process called list scrubbing.
This is an important practice you should do regularly to maintain high email deliverability rates. Imagine that your list increases by 1,000 new subscribers each month, but 300 of them become inactive in the next month. In a year, you would have 12,000 new subscribers but also 3,600 inactive.
You want as many happy and engaged subscribers as possible to open your emails each time you send one because this tells email service providers that your reputation is clean and your messages are reputable and valuable for your subscribers.
So, by scrubbing your list each quarter or every six months, you will ensure that only people who are currently interested in your brand receive your emails, which will result in a higher open rate and better email deliverability.
Before you delete inactive subscribers, you can send them a "last call" email asking them to reconfirm their interest in receiving marketing emails from you. If they fail to respond within a week or so, you can safely delete them from your list.
### Final Thoughts
As you can see, there are many things that you can do to increase your email deliverability rates and ensure that your emails land in your subscribers' inboxes. During this process, you should constantly check your [email analytics](https://www.monsterinsights.com/email-marketing-metrics-and-kpis/) and make changes based on your target audience. Before long, you should be able to understand and reduce your email deliverability rate. | syedbalkhi |

1,880,060 | Bridging the Gap: Integrating Microsoft Copilot with Zendesk Using Sunshine Conversations | Introduction In today's digital landscape, seamless integration between various tools is essential... | 0 | 2024-06-07T08:15:28 | https://dev.to/hariraghupathy/bridging-the-gap-integrating-microsoft-copilot-with-zendesk-using-sunshine-conversations-l6f |
**Introduction**
In today's digital landscape, seamless integration between various tools is essential for efficient operations and enhanced user experience. Recently, we embarked on a journey to integrate Microsoft Copilot with Zendesk, despite the lack of direct connectivity. This blog post details our collaborative effort with Zendesk and Microsoft, leveraging Sunshine Conversations to achieve this integration.
**The Challenge**
Microsoft Copilot is a powerful tool for automating tasks and enhancing productivity. However, it does not have native connectivity to Zendesk, a popular customer service platform. This posed a significant challenge, as no existing solutions or community efforts had addressed this gap.
**The Solution**
To overcome this challenge, we worked closely with both Zendesk and Microsoft. Our solution involved leveraging Sunshine Conversations, a powerful API for integrating various messaging channels. The process was as follows:
**Sequence of API Calls:** When an agent interaction is initiated, we trigger a series of API calls – createUser, createConversation, and postMessage. These calls create a ticket in Zendesk and pass all basic information, including the conversation transcript.
**Webhook Creation: **We developed a webhook using JavaScript/TypeScript and deployed it on a serverless solution. This webhook is responsible for sending and receiving messages between Copilot and Zendesk via Sunshine Conversations.
**Event Handling:** The webhook listens for the ticket:closed event from Zendesk. Upon receiving this event, the webhook ends the conversation on our side, ensuring a seamless closure.
**Step-by-Step Implementation**
**Step 1: Sequence of API Calls**
When a user requests to talk to an agent, the following API calls are made:
**createUser:** This API call creates a new user in the Sunshine Conversations platform.
**createConversation:** This call initiates a new conversation for the user.
**postMessage:** Finally, this API sends the initial message from Copilot to the newly created conversation.
This sequence ensures that all relevant information is captured and a ticket is created in Zendesk.
**Step 2: Webhook for Message Handling**
We developed a webhook that handles communication between Copilot and Zendesk. The webhook performs the following tasks:
Sends messages from Copilot to Zendesk via Sunshine Conversations.
Receives responses from Zendesk and relays them back to Copilot.
The webhook is deployed on a serverless platform, ensuring scalability and reliability.
**Step 3: Event Handling**
The webhook listens for the **ticket:closed** event from Zendesk. When this event is detected, the webhook performs necessary actions to end the conversation on our side, maintaining consistency and ensuring a smooth user experience.
**Conclusion**
By collaborating with Zendesk and Microsoft, and leveraging Sunshine Conversations, we successfully bridged the gap between Microsoft Copilot and Zendesk. This integration enables seamless communication and enhances the overall efficiency of our customer service operations.
Our journey demonstrates the power of collaborative efforts and innovative solutions in overcoming technical challenges. We hope this blog post provides valuable insights and inspiration for your own integration projects. | hariraghupathy | |

The guidelines concern both the tool's configuration and its application in everyday work and assume the reader will use GitHub Copilot with IntelliJ IDEA (via a dedicated plugin).**
## GitHub Copilot – What is it?
GitHub Copilot is an AI developer assistant that uses a generative AI model trained for all programming languages available in GitHub repositories. The full description and documentation of the tool is available here.
There are other similar tools on the market, such as OpenAI Codex, JetBrains AI Assistant or Tabnine, but GitHub Copilot stands out due to the following features:
1. The largest and most diverse collection for training an AI model – GitHub repositories
2. Estimated usage share – currently approx. 40-50% (according to [Abhay Mishra’s article](https://dzone.com/articles/comparison-of-various-ai-code-generation-tools-ava) based on undisclosed industry insights), but the market is very dynamic
3. Support for popular technologies – we’ve tested it with the Java programming language, Scala, Kotlin, Groovy, SQL, Spring, Dockerfile, OpenShift, Bash
4. Very good integration with the JetBrains IntelliJ IDEA IDE
5. Low entry-level due to quick and easy configuration, general ease of use, clear documentation, and many usage examples on the internet
6. A wide range of functionalities, including:
- Suggestions while writing code
- Generating code based on comments in natural language
- Taking existing code into account when generating a new code snippet
- Creating unit tests
- Chat – allows you to ask questions regarding code, language, and technology, as well as suggests corrections for simplifying the code
- CLI – support for working in the console and creating bash scripts
## Our goals
Our main goal for using GitHub Copilot was to improve the efficiency of writing code and its quality. In addition, we intended it to support and assist us in work in which programmers lack knowledge and experience. Here are the specific goals that we wanted our development team to achieve by using GitHub Copilot:
**1. Accelerating development:**
- Generating code fragments
- Generating SQL queries
- Hints for creating and modifying OpenShift and Dockerfile configuration files
- Faster search for solutions using the chat function, e.g., explanation of regular expressions, operation of libraries or framework mechanisms
**2. Improving code quality:**
- Generating unit tests with edge cases – both in Java and Groovy languages
- Suggesting corrections and simplifications in our own code
**3. Working with less frequently used technologies:**
- Explaining and generating code (including unit tests) in Scala and Kotlin
- Support while using “legacy” solutions like Activiti, etc.
- Support in creating and understanding configuration files
**4. More efficient administrative work in the console using CLI functions**
## Tool limitations guidelines
Since GitHub Copilot is based on generative AI, you must always remember that it may generate incorrect code or responses. Therefore, when using the tool, you must be aware of potential limitations and apply the principle of limited trust and verification. The main limitations are presented in the table below.
To minimize the negative impact of the identified GitHub Copilot limitations, you should always:
- Check alternative suggestions (using **Ctrl+[** and **Ctrl+]**, etc.) and choose the ones that best suit a given situation
- Read and analyze the correctness of the generated code
- Test and run code in pre-production environments – primarily locally and in the development environment
- Submit the generated code to code review
**Important: Never deploy the code generated by GitHub Copilot to production environments without performing the above checks.**
## Configuration guidelines
In this section, we’ll present the basic information regarding the pricing plans (with advantages and disadvantages for each option, as seen from the perspective of our intended goals) and personal account configuration (for both GitHub Copilot and the IntelliJ IDEA plugin).
### Pricing plans
GitHub Copilot offers [three subscription plans](https://docs.github.com/en/copilot/copilot-individual/about-github-copilot-individual#understanding-the-differences-between-copilot-individual-copilot-business-and-%20copilot-enterprise) with different scopes of offered functionality and cost. In our case, two plans were worth considering: Copilot Individual or Copilot Business. The Copilot Enterprise plan additionally offers access to chat via the github.com website and generating summaries for pull requests, which was unimportant for our assumed goals (but it may be different in your case). Both plans' main advantages and disadvantages are presented in the table below.
In our case, Copilot Business was the better option, especially because it allows full control over the configuration and access to the tool for developers in the team. If you’re working on your own, the Copilot Individual plan might be enough.
### Account configuration
You can configure GitHub Copilot when purchasing a subscription plan, and the settings can also be changed after activating the account in the organization's account settings on [GitHub](https://github.com/). At the account level, there were two key parameters for our use case to configure in GitHub Copilot, described in the table below.
[Here](https://docs.github.com/en/copilot/configuring-github-copilot/configuring-github-copilot-settings-on-githubcom) is a detailed description and instructions for changing configuration options in your GitHub account.
### IntelliJ IDEA plugin configuration
To enable GitHub Copilot in the IntelliJ IDEA IDE, you must install GitHub Copilot extension from the [Visual Studio Code marketplace](https://marketplace.visualstudio.com/items?itemName=GitHub.copilot). Installation is done via the IDE in the plugin settings. After installation, log in to your GitHub account with your device code. You can find detailed instructions for installing and updating the plugin [here](https://docs.github.com/en/copilot/using-github-copilot/using-github-copilot-code-suggestions-in-your-editor#installing-the-github-copilot-plugin-in-your-jetbrains-ide).
The GitHub Copilot plugin for the IntelliJ IDEA IDE offers the ability to configure the following things:
- Automatic submission of suggestions
- The way suggestions are displayed
- Automatic plugin updates
- Supported languages
- Keyboard shortcuts
In our case, using the default plugin settings was recommended because they ensure good working comfort and are compatible with the existing tool documentation. Any changes to the configuration can be made by each user according to their own preferences.

1,880,047 | Getting Stale Data for ActiveRecord Associations in Rails: `Model.reload` to fetch latest data | Issue I encountered a bug where Associations were referencing stale data. Here's the... | 0 | 2024-06-07T08:12:13 | https://dev.to/takuyakikuchi/getting-stale-data-for-activerecord-associations-in-rails-modelreload-to-fetch-latest-data-282a | rails | ## Issue
I encountered a bug where Associations were referencing stale data.
Here's the sample scenario(generated by ChatGPT):
**Initial State: Fetching pets**
```ruby
class Person < ActiveRecord::Base
has_many :pets
end
# Fetching pets from the database
person = Person.find(1)
pets = person.pets
# => [#<Pet id: 1, name: "Snoop", group: "dogs", person_id: 1>]
```
**Database Update: Adding a new pet**
```ruby
# Simulating a direct database update (could be from another part of the application or an external source)
Pet.create(name: "Whiskers", group: "cats", person_id: 1)
```
**Accessing cached pets 🔴*
```ruby
cached_pets = person.pets
# => [#<Pet id: 1, name: "Snoop", group: "dogs", person_id: 1>]
```
At this point, `cached_pets` does not include the new pet "Whiskers" because the pets association is using the cached value.
## Solution
`.reload`
**Accessing pets with reload**
```ruby
updated_pets = person.pets.reload
# => [#<Pet id: 1, name: "Snoop", group: "dogs", person_id: 1>, #<Pet id: 2, name: "Whiskers", group: "cats", person_id: 1>]
```
## Reference
```rb
# Reloads the collection from the database. Returns +self+.
#
# class Person < ActiveRecord::Base
# has_many :pets
# end
#
# person.pets # fetches pets from the database
# # => [#<Pet id: 1, name: "Snoop", group: "dogs", person_id: 1>]
#
# person.pets # uses the pets cache
# # => [#<Pet id: 1, name: "Snoop", group: "dogs", person_id: 1>]
#
# person.pets.reload # fetches pets from the database
# # => [#<Pet id: 1, name: "Snoop", group: "dogs", person_id: 1>]
def reload
proxy_association.reload(true)
reset_scope
end
```

1,880,055 | SOA vs Microservices – 8 key differences and corresponding use cases | Nowadays, for businesses, building scalable and agile applications is crucial for responding swiftly... | 0 | 2024-06-07T08:11:56 | https://dev.to/gem_corporation/soa-vs-microservices-8-key-differences-and-corresponding-use-cases-2og7 | microservices, softwaredevelopment, softwareengineering | Nowadays, for businesses, building scalable and agile applications is crucial for responding swiftly to changes in customer demand, technological advancements, and market conditions.
This is where [software architectures](https://gemvietnam.com/others/soa-vs-microservices/?utm_source=Devto&utm_medium=click) like Service-oriented architecture (SOA) and Microservices come into play. Both approaches offer ways to decompose complex functionalities into smaller, manageable units. However, choosing the right one for your project can be a challenge. This article will explore the key differences between them, helping you decide which architecture best suits your needs.
## SOA vs Microservices – The definitions
First, let’s briefly recap the definitions of these terms.
**Service-oriented architecture (SOA)**
This is a design paradigm and architectural pattern where functionality is grouped into services, which are discrete and reusable software units that can be independently developed, deployed, and maintained. These services communicate over a network using standardized protocols and interfaces.
Key characteristics of this architecture include:
Loose coupling: Services are independent of each other, minimizing dependencies which allows for easier maintenance and updates.
Interoperability: Services can interact with each other and with other systems regardless of the platform or the technology used, facilitated by using common communication standards like HTTP, SOAP, or REST.
Reusability: Services are designed to be reused in different scenarios and applications, promoting efficiency and reducing redundancy.
Abstraction: The service’s implementation details are hidden from the end users and other services.
**Microservices architecture**
[Microservices architecture](https://gemvietnam.com/others/soa-vs-microservices/?utm_source=Devto&utm_medium=click) is an approach to developing a single application as a suite of small, independently deployable services, each running in its own process and communicating with lightweight mechanisms, often an HTTP-based API. Each microservice is tightly focused on a specific business function and can be developed, deployed, and scaled independently.
For example, many business processes within an organization require user authentication functionality. Instead of having to rewrite the authentication code for all business processes, you can create and reuse a single authentication service for all applications. Similarly, most healthcare systems, such as patient management systems and electronic health record (EHR) systems, require patient registration. These systems can call a common service to perform the patient registration task.
The key characteristics of it are:
Highly easy to maintain and test: With microservices, the development team can easily test each component and perform maintenance. Therefore, this approach enables them to offer quick, regular, and reliable deliveries, even with large and complex applications.
Loosely coupled: Each service is a separate component and can be developed, deployed, and scaled independently.
Organized around business capabilities: These architectures are organized around business capabilities and priorities rather than technologies.
Ownership: Microservices promote decentralized governance and data management, where small teams own a specific service from top to bottom.
**What they have in common**
From the definitions provided above, it can be said that in essence, SOA provides a solid foundation for building service-based applications, while microservices push the boundaries further by creating an even more modular and independently deployable architecture.
While both of them share principles like service reusability and modular design, they differ significantly in scale, granularity, and management practices. Microservices can be seen as an evolution of SOA, adapted for the contemporary emphasis on continuous delivery and scalable cloud infrastructure.
At this point, you might feel they are quite similar and get confused: “How can I know which one is best for me?” In the section that follows, let’s learn more about their differences.
## SOA vs Microservices – Key differences and corresponding use cases
This table offers a comprehensive comparison of the two approaches in question based on different criteria: Architectural style, service granularity, service independence, communication, data storage, deployment, and coupling.
We can see that in all aspects, both models were developed to address the inherent disadvantages of the Monolith. Both aim to improve the flexibility, scalability, and maintainability of software systems, but they have different architectural principles, detail levels, management models, and deployment characteristics.
Therefore, the scope of application for the two models is quite different: Microservices are closely associated with the concepts of connecting services/functions within a service/system, while SOA is applied to integrate/connect multiple enterprise services/systems with each other.
In the next part, we will delve deeper into what problem each of these approach would be best for solving.
## Use cases for SOA
This approach is more suited for larger, more integrated solutions that require uniform, enterprise-wide approaches and are less about scaling or continuous deployment.
**Enterprise application integration**
It is usually employed in scenarios where multiple existing enterprise applications need to be integrated. Also, it is often used in large enterprises to ensure that different applications, possibly written in different programming languages and running on different platforms, can work together smoothly.
**Legacy system modernization**
Companies with legacy systems can use SOA to gradually expose legacy system functionalities as services. This allows other systems to utilize these services without disrupting the current system and facilitates a smoother transition to newer technologies.
**Business process management**
SOA is beneficial for automating and optimizing complex business processes. It allows organizations to define business services that can be reused across different business processes, enhancing consistency and efficiency.
**Regulatory compliance and reporting**
In sectors like finance or healthcare, where systems need to adapt rapidly to new regulations, SOA can help by modularizing the compliance functionalities into services that can be updated as needed without extensive system-wide overhauls.
## Use cases for microservices
Meanwhile, microservices are more agile and suited for dynamic, cloud-based environments where services need to be independently scalable and deployable, often with a focus on using containerization technologies like Docker and Kubernetes.
**Scalable cloud applications**
This approach is ideal for applications that require high scalability and reliability. Each service can be scaled independently, allowing for efficient use of resources and reducing costs in cloud environments.
**Continuous deployment and delivery**
Organizations that aim for rapid development cycles with continuous integration and deployment will benefit from this architecture. Since each microservice is independent, updates and improvements can be deployed to individual services without affecting the entire application.
**Decentralized data management**
For applications requiring different data management technologies (like SQL, NoSQL) based on the specific needs of each service, microservices allow for decentralized data governance, which can optimize performance and data management.
**Diverse technology stacks**
If different components of an application warrant using different technology stacks to optimize performance, this architecture provides the flexibility to implement each service in the most appropriate technology.
In short:
[SOA](https://gemvietnam.com/others/soa-vs-microservices/?utm_source=Devto&utm_medium=click) is more suited for larger, more integrated solutions that require uniform, enterprise-wide approaches and are less about scaling or continuous deployment.
Microservices are more agile and suited for dynamic, cloud-based environments where services need to be independently scalable and deployable, often with a focus on using containerization technologies like Docker and Kubernetes.

1,880,046 | Higher Order Components (HOC) in React js | A Higher-Order Component (HOC) is an advanced technique for reusing component logic. HOCs are not... | 0 | 2024-06-07T08:02:04 | https://dev.to/imashwani/higher-order-components-hoc-in-react-js-d8a | react, beginners, webdev, hoc | A Higher-Order Component (HOC) is an advanced technique for reusing component logic. HOCs are not part of the React API, but rather a pattern that emerges from React’s compositional nature.
A higher-order component is a function that takes a component as an argument and returns a new component that wraps the original component
This allows you to add additional functionality to the component without modifying its original code. HOCs are commonly used to share common functionality between multiple components, such as state modification or props change.
## **1. Creating a Higher-Order Component:**
```
import React from 'react';
// This is the HOC function
function withCounter(WrappedComponent) {
class WithCounter extends React.Component {
constructor(props) {
super(props);
this.state = {
count: 0,
};
}
handleIncrement = () => {
this.setState((prevState) => {
return { count: prevState.count + incremntNuber };
});
};
render() {
return (
<WrappedComponent
count={count}
incrementHandler={this.handleIncrement}
{...this.props}
/>
);
}
}
return WithCounter;
}
```
## **2. Using the HOC:**
```
// A simple component
function MyComponent(props) {
return (
<button onClick={props.incrementHandler}>
{props.name} Click {props.count} times
</button>
);
}
// Wrap the component with the HOC
const EnhancedComponent = withCounter(MyComponent);
// Usage
function App() {
return <EnhancedComponent name="Hello World!" />;
}
```
> In this example, withCounter is the **HOC** that adds some extra information to the **MyComponent** component. When **EnhancedComponent** is used, it renders MyComponent with the original props along with the additional paragraph containing "Some extra information".
## **3. Key Points About HOCs:**
**Pure Functions:** HOCs should be pure, meaning they should not modify the original component. Instead, they should create a new component that wraps the original one.
**Props Proxy:** HOCs can pass props to the wrapped component. This pattern is useful for injecting additional props or modifying existing ones before passing them down.
**Composability:** HOCs can be composed. You can create multiple HOCs and apply them to a component sequentially.
**Convention:** It's a common convention to name HOCs with a prefix like with, such as withRouter or withUser, to indicate that it's an HOC.
**Static Methods:** HOCs do not copy static methods from the wrapped component. If the wrapped component has static methods that need to be accessed, you’ll need to manually copy them.
Here’s an example of ensuring static methods are preserved:
```
import React from 'react';
// Helper function to copy static methods
function hoistStatics(targetComponent, sourceComponent) {
const keys = Object.getOwnPropertyNames(sourceComponent);
keys.forEach(key => {
if (!targetComponent.hasOwnProperty(key)) {
targetComponent[key] = sourceComponent[key];
}
});
return targetComponent;
}
function withExtraInfo(WrappedComponent) {
class HOC extends React.Component {
render() {
return (
<div>
<WrappedComponent {...this.props} />
<p>Some extra information</p>
</div>
);
}
}
// Copy static methods
hoistStatics(HOC, WrappedComponent);
return HOC;
}
```
## **Conclusion:**
HOCs are a powerful pattern in React for reusing component logic, but they should be used judiciously to avoid overly complex component hierarchies.

```
const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true });
const Schema = mongoose.Schema;
const userSchema = new Schema({
name: String,
email: String,
password: String
});
const User = mongoose.model('User', userSchema);
```
`mongoose` simplifies interactions with MongoDB, providing a powerful schema-based model for your data.
## 6\. jsonwebtoken
JWT (JSON Web Token) is a popular method for implementing authentication. The `jsonwebtoken` package allows you to generate and verify JWT tokens, which can be used for securing your API.
### Installation
```
npm install jsonwebtoken
```
### Usage
```
const jwt = require('jsonwebtoken');
const token = jwt.sign({ userId: 123 }, 'your-secret-key', { expiresIn: '1h' });
jwt.verify(token, 'your-secret-key', (err, decoded) => {
if (err) {
console.log('Token is invalid');
} else {
console.log('Token is valid', decoded);
}
});
```
`jsonwebtoken` makes it easy to implement stateless authentication, ensuring your application remains secure.
## 7\. dotenv
Managing environment variables is crucial for configuration management in any application. `dotenv` is a zero-dependency module that loads environment variables from a `.env` file into `process.env`.
### Installation
```
npm install dotenv
```
### Usage
```
require('dotenv').config();
const port = process.env.PORT || 3000;
app.listen(port, () => {
console.log(\`Server running on port ${port}\`);
});
```
`dotenv` helps you keep sensitive data and configuration out of your codebase, promoting best practices for application deployment and security.
## Conclusion
The Express.js ecosystem is vast, and these packages are just the tip of the iceberg. Integrating these popular packages into your Express.js projects can significantly enhance functionality, improve security, and simplify development.

This is where Rake (Ruby Make) tasks come in handy. In this article, I'll guide you through creating and scheduling Rake tasks in a Rails application.
## What is a Rake Task?
Rake is a build automation tool written in Ruby. It allows you to define and run tasks using a simple Ruby DSL. In Rails, Rake tasks are commonly used for tasks like database migrations (`rake db:migrate`), cleaning logs (`rake log:clear`), and many other maintenance tasks.
## Creating a Custom Rake Task
Let's start by creating a custom Rake task. Suppose you want to delete all PDF files in your `public/pdfs` directory every night. Here's how you can do it.
### Step 1: Define the Rake Task
First, create a new Rake task file in the `lib/tasks` directory. We'll name it `delete_pdfs.rake`.
```sh
mkdir -p lib/tasks
touch lib/tasks/delete_pdfs.rake
```
Open `lib/tasks/delete_pdfs.rake` and add the following content:
```ruby
# lib/tasks/delete_pdfs.rake
namespace :pdf do
desc "Delete all PDFs from public/pdfs and its subdirectories older than midnight"
task delete: :environment do
require 'fileutils'
pdf_directory = Rails.root.join('public', 'pdfs')
if Dir.exist?(pdf_directory)
Dir.glob(File.join(pdf_directory, '**', '*.pdf')).each do |file|
FileUtils.rm(file)
puts "Deleted #{file}"
end
else
puts "Directory #{pdf_directory} does not exist"
end
end
end
```
### Step 2: Run the Rake Task
You can run your new Rake task from the command line:
```sh
bundle exec rake pdf:delete
```
This command will delete all PDF files in the `public/pdfs` directory and its subdirectories.
## Scheduling the Rake Task
To run the task automatically at midnight every day, you can use the `whenever` gem, which provides a clear syntax for writing and deploying cron jobs.
### Step 1: Add the `whenever` Gem
Add `whenever` to your `Gemfile`:
```ruby
gem 'whenever', require: false
```
Run `bundle install` to install the gem.
### Step 2: Configure `whenever`
Initialize `whenever` in your project:
```sh
bundle exec wheneverize .
```
This command creates a `config/schedule.rb` file. Open this file and add the following content:
```ruby
# config/schedule.rb
# Set the environment
set :environment, "development" # or "production"
# Define the task schedule
every :day, at: '12:00 am' do
puts 'Delete pdf files'
rake "pdf:delete"
end
```
### Step 3: Update Cron Jobs
Update your cron jobs by running:
```sh
bundle exec whenever --update-crontab
```
This command writes the schedule defined in `config/schedule.rb` to your crontab, ensuring that the task runs at the specified time.
### Step 4: Verify the Task
Manually run the task to ensure it works correctly:
```sh
bundle exec rake pdf:delete
```
## Conclusion
Rake tasks are a powerful way to automate repetitive tasks in your Rails application. By combining Rake with `whenever`, you can schedule these tasks to run automatically, making your workflow more efficient.
I hope this guide helps you get started with creating and scheduling Rake tasks in your Rails projects. If you have any questions or tips of your own, feel free to share them in the comments below!
Happy coding!

In this enlightening podcast, he shares his journey from AI to the cloud-native world with Bart Farrell.
Discover William's cost-saving strategies for service meshes, gain insights into the ongoing debate between sidecars, Ambient Mesh, and Cilium Cluster Mesh, his surprising connection to Twitter's early days and unique perspective on balancing tech expertise with the humility of being a piano student.
You can watch (or listen) to this interview [here](https://kube.fm/service-mesh-william).
**Bart**: Imagine you've just set up a fresh Kubernetes cluster. What's your go-to trio for the first tools to install?
**William**: My first pick would be [Linkerd](https://linkerd.io/). It's a must-have for any Kubernetes cluster. I then lean towards tools that complement Linkerd, like [Argo ](https://argo-cd.readthedocs.io/en/stable/)and [cert-manager](https://cert-manager.io/). You're off to a solid start with these three.
**Bart**: Cert Manager and Argo are popular choices, especially in the GitOps domain. What about [Flux](https://fluxcd.io/)?
**William**: Flux would work just fine. I don't have a strong preference between the two. Flux and Argo are great options, especially for tasks like progressive delivery. When paired with Linkerd, they provide a robust safety net for rolling out new code.
**Bart**: As the CEO, who are you accountable to? Could you elaborate on your role and responsibilities?
**William**: Being a CEO is an exciting shift from my previous role as an engineer. I work for myself, and I must say, I’m a demanding boss. As a CEO, I focus on the big picture and align everyone toward a common goal. These are the two skills I’ve had to develop rapidly since transitioning from an engineer, where my primary concern was writing and maintaining code.
**Bart**: From a technical perspective, how did you transition into the cloud-native space? What were you doing before it became mainstream?
**William**: My early career was primarily focused on AI, [NLP](https://en.wikipedia.org/wiki/https://en.wikipedia.org/wiki/Natural_language_processing), and machine learning long before they became trendy. I thought I’d enter academia but realized I enjoyed coding more than research.
I worked at several Bay Area startups, mainly in NLP and machine learning roles. I was part of a company called PowerSet, which was building a natural language processing engine and was acquired by Microsoft. I then joined Twitter in its early days, around 2010, when it had about 200 employees. I started on the AI side but transitioned to infrastructure because I found it more satisfying and challenging. We were doing what I now describe at Twitter as cloud-native, even though the terminology differed. We didn’t have Kubernetes or Docker, but we had [Mesos](https://mesos.apache.org/), the JVM for isolation, and cgroups for a basic form of containerization. We transitioned from a monolithic Ruby on Rails service to a massive microservices deployment. When I left Twitter, we tried to apply those same ideas to the emerging world of Kubernetes and Docker.
**Bart**: How do you keep up with the rapid changes in the Kubernetes and cloud-native ecosystems, especially transitioning from infrastructure and AI/NLP?
**William**: My current role primarily shapes my strategy. I learn a lot from the engineers and users of [Linkerd](https://www.reddit.com/r/linkerd/new/), who are at the forefront of these technologies. I also keep myself updated by reading discussions on Reddit platforms like [r/kubernetes](https://www.reddit.com/r/kubernetes/) and [r/Linkerd](https://www.reddit.com/r/linkerd/new/). Occasionally, I contribute to or follow discussions on [Hacker News](https://news.ycombinator.com/). Overall, my primary source of knowledge comes from the experts I work with daily, giving me valuable insights into the latest developments.
**Bart**: If you could return to your time at Twitter or even before that, what one tip would you give yourself?
**William**: I'd tell myself to prioritize impact. As an engineer, I was obsessed with building and exploring new technologies, which was rewarding. However, I later understood the value of stepping back to see where I could make a real difference in the company. Transitioning my focus to high-impact areas, such as infrastructure at Twitter, was a turning point. Despite my passion for NLP, I realized that infrastructure was where I could truly shine. Always look for opportunities where you can make the most significant impact.
**Bart**: Let’s focus on "[Sidecarless eBPF Service Mesh Sparks Debate](https://www.techtarget.com/searchitoperations/news/365535362/Sidecarless-eBPF-service-mesh-sparks-debate)," which follows up on your previous article “[eBPF, sidecars, and the future of the service mesh](https://buoyant.io/blog/ebpf-sidecars-and-the-future-of-the-service-mesh).” You're one of the creators of Linkerd. For those unfamiliar, what exactly is a service mesh? Why would someone need it, and what value does it add?
**William**: There are two ways to describe service mesh: what it does and how it works. Service mesh is an additional layer for Kubernetes that enhances key areas Kubernetes doesn't fully address.
The first area is security. It ensures all connections in your cluster are encrypted, authorized, and authenticated. You can set policies based on services, gRPC methods, or HTTP routes, like allowing Service A to talk to /foo but not /bar.
The second area is reliability. It enables graceful failovers, transparent traffic shifting between clusters, and progressive delivery. For example, deploying new code and gradually increasing traffic to it to avoid immediate production traffic. It also includes mechanisms like load balancing, circuit breaking, retries, and timeouts.
The last area is observability. It provides uniform metrics for all workloads across all services, such as success rates, latency distribution, and traffic volume. Importantly, it does this without requiring changes to your application code.
The most prevalent method today involves using many proxies. This approach has become feasible thanks to technological advancements like Kubernetes and containers, which simplify the deployment and management of many proxies as a unified fleet. A decade ago, deploying 10,000 proxies would have been absurd, but it is feasible and practical today. The specifics of deploying these proxies, their locations, programming languages, and practices are subject to debate. However, at a high level, service meshes work by running these layer seven proxies that understand HTTP, HTTP2, and gRPC traffic and enable various functionalities without requiring changes to your application code.
**Bart**: Can you briefly explain [how the data and control planes work in service meshes](https://blog.envoyproxy.io/service-mesh-data-plane-vs-control-plane-2774e720f7fc), especially compared to the older sidecar model with an extra container?
**William**: A service mesh architecture consists of two main components: a control plane and a data plane. The control plane allows you to manage and configure the data plane, which directs network traffic within the service mesh. In Kubernetes, the control plane operates as a collection of standard Kubernetes services, typically running within a dedicated namespace or across the entire cluster.
The data plane is the operational core of a service mesh, where proxies manage network traffic. The sidecar model, employed by service meshes like Linkerd, deploys a dedicated proxy alongside each application pod. Therefore, a service mesh with 20 pods would have 20 corresponding proxies. The overall efficiency and scalability of the service mesh rely heavily on the size and performance of these individual proxies.
In the sidecar model, service A and service B communication flows through service A's and service B's proxy. Service A sends its message to its sidecar proxy, and then the service A proxy forwards it to service B's sidecar proxy. Finally, service B's proxy delivers the message to service B itself. This indirect communication path adds extra hops, leading to a slight increase in latency. You must carefully consider the potential performance impacts to ensure that service mesh benefits outweigh the trade-offs.
**Bart**: We've been discussing the benefits of service meshes, but running an extra container for each pod sounds expensive. Does cost become a significant issue?
**William**: Service meshes have a compute cost, just like adding any component to a system. You pay for CPU and memory, but memory tends to be the more significant concern, as it can force you to scale up instances or nodes.
However, Linkerd has minimized this issue with a "micro proxy" written in Rust. Rust's strict memory management allows fast, lightweight proxies and avoids memory vulnerabilities like buffer overflows, which are common in C and C++. Studies from both [Google](https://security.googleblog.com/2024/03/secure-by-design-googles-perspective-on.html) and Microsoft have shown that roughly 70% of security bugs in C and C++ code are due to memory management errors.
Our choice of Rust as the programming language in 2018 was a calculated risk. Rust offers the best of both worlds: the speed and control of languages like C/C++ and the safety and ease of use of languages with runtime environments like Go. Rust and its network library ecosystem were still relatively young at that time. We invested significantly in underlying libraries like [Tokio](https://tokio.rs/), [Tower](https://github.com/tower-rs/tower), and H2 to build the necessary infrastructure.
The critical role of the data plane in handling sensitive application data drove this decision. We ensured its reliability and security. Rust enables us to build small, fast, and secure proxies that scale with traffic, typically using minimal memory, directly translating to the user experience. Instead of facing long response times (like 5-second tail latencies), users experience faster interactions (closer to 30 milliseconds). A service mesh can optimize these tail latencies, improving user experience and customer retention. Choosing Rust has proven to be instrumental in achieving these goals.
While cost is a factor, the actual cost often stems from operational complexity. Do you need dedicated engineers to maintain complex proxies, or does the system primarily work independently? That human cost usually dwarfs the computational one.
Our design choices have made managing Linkerd’s costs relatively straightforward. However, for other service meshes, costs can escalate if the proxies are large and resource-intensive. Even so, the more significant cost is often not the resources but the operational overhead and complexity. This complexity can demand considerable time and expertise, increasing the overall cost.
**Bart**: You raise a crucial point about the human aspect. While we address technical challenges, the time spent resolving errors detracts from other tasks. The community has developed products and projects to tackle these concerns and costs. One such example is [Istio](https://istio.io/) with Ambient Mesh. Another approach is sidecarless service meshes like Cilium Cluster Mesh. Can you explain what Ambient Mesh is and how it enhances the classic sidecar model of service meshes?
**William**: We've delved deep into both of these options in Linkerd. While there might come a time when adopting these projects makes sense for us, we're not there yet.
Every decision involves trade-offs regarding distributed systems, especially in production environments within companies where the platform is a tool to support applications. At Linkerd, our priority is constantly reducing the operational workload.
Ambient Mesh and eBPF aren't primarily reactions to complexity but responses to the practical annoyances of sidecars. Their key selling point is eliminating the need for sidecars. However, the real question is: What's the cost of this shift? That's where the analysis becomes crucial.
In Ambient Mesh, rather than having sidecar containers, you utilize connective components, such as tunnels, within the namespace. These tunnels communicate with proxies located elsewhere in the cluster. So essentially, you have multiple proxies running outside of the pod, and the pods use these tunnels to communicate with the proxies, which then handle specific tasks.
This setup is indeed intriguing. As mentioned earlier, running sidecars can be challenging due to specific implications. One such implication is the cost factor, which we discussed earlier. In Linkerd’s case, this is a minor concern. However, a more significant implication is the need to restart the pod to upgrade the proxy to the latest version, given the immutability of pods in Kubernetes.
This situation necessitates managing two separate updates: one to keep the applications up-to-date and another to upgrade the service mesh. Therefore, while the setup has advantages, it also requires careful management to ensure smooth operation and optimal performance.
We operate the proxy as the first container for various reasons, which can lead to friction points, such as when using `kubectl logs`. Typically, when you request logs, you're interested in your application's logs, not the proxy's. This friction, combined with a desire for networking to operate seamlessly in the background, drives the development of solutions like Ambient and eBPF, which aim to eliminate the need for explicit sidecars.
Both Ambient and eBPF solutions, which are closely related, are reactions to this sentiment of not wanting to deal with sidecars directly. The aim is to make sidecars disappear. Take [Istio](https://istio.io/) and most service meshes built on [Envoy](https://www.envoyproxy.io/), for instance. Envoy is complex and memory-intensive and requires constant attention and tuning based on traffic specifics.
Challenges with sidecars are more of a cloud-native trend to market solutions, like writing a blog post proclaiming the [death of sidecars](https://thenewstack.io/ambient-mesh-no-sidecar-required/) rather than being specific to Linkerd. They can sometimes be an inaccurate reflection of the reality of engineering.
In Ambient, eliminating sidecars by running the proxy elsewhere and using tunnel components allows for separate proxy maintenance without needing to reboot applications for upgrades. However, in a Kubernetes environment, the idea is that pods should be rebootable anytime. Kubernetes can reschedule pods as needed, which aligns with the principles of building applications as distributed systems. Yet, there are legacy applications or specific scenarios where rebooting could be more convenient, making the sidecar approach less appealing.
Historically, running cron jobs with sidecar proxies in Kubernetes posed a significant challenge. Kubernetes lacked a built-in mechanism to signal the sidecar proxy when the main job was complete, necessitating manual intervention to prevent the proxy from running indefinitely. This manual process went against the core principle of service mesh, which aims to decouple services from their proxies for easier management and scalability.
Thankfully, one significant development is the [Sidecar Container Kubernetes Enhancement Proposal](https://kubernetes.io/blog/2023/08/25/native-sidecar-containers/). With this enhancement, you can designate your proxy as a sidecar container, leading to several benefits, like jobs terminating the proxy once finished and eliminating unnecessary resource consumption.
For Linkerd, adopting Ambient mesh architecture introduces more complexity than benefits. The additional components, like the tunnel and separate proxies, add unnecessary layers to the system. Unlike Istio, which has encountered issues due to its architecture, Linkerd's existing design hasn't faced similar challenges. Therefore, the trade-offs associated with Ambient aren't justified for Linkerd.
In contrast, the sidecar model offers distinct advantages. It creates clear operational and security boundaries at the pod level. Each pod becomes a self-contained unit, making independent decisions regarding security and operations, aligning with Kubernetes principles, and simplifying management in a cloud-native environment.
This sidecar approach is crucial for implementing [zero-trust](https://www.cloudflare.com/learning/security/glossary/what-is-zero-trust/#:~:text=Zero%20Trust%20security%20is%20an,outside%20of%20the%20network%20perimeter.) security. The critical principle of zero trust is to enforce security policies at the most granular level possible. Traditional approaches relying on a perimeter firewall and implicitly trusting internal components are no longer sufficient. Instead, each security decision must be made independently at every system layer. This granular enforcement is achieved by deploying a sidecar proxy within each application pod, acting as a security boundary and enabling fine-grained control over network traffic, authentication, and authorization.
In Linkerd, every request undergoes a rigorous security check within the pod. This check includes verifying the validity of the TLS encryption, confirming the client's identity through cryptographic algorithms, and ensuring the request comes from a trusted source. Additionally, Linkerd checks whether the request can access the specific resource or method it's trying to reach. This multi-layered scrutiny happens directly inside the pod, providing the highest possible level of security within the Kubernetes framework. Maintaining this tight security model is crucial, as any deviation, like separating the proxy and TLS certificate, weakens the model and introduces potential vulnerabilities.
**Bart**: The next point I'd like to discuss has garnered significant attention in recent years through [Cilium Service Mesh](https://cilium.io/use-cases/service-mesh/) and various domains. What is eBPF?
**William**: eBPF is a kernel technology that enables the execution of specific code within the kernel, offering significant advantages. Firstly, operations within the kernel are high-speed, eliminating the overhead of context switching between kernel and user space. Secondly, the kernel has unrestricted access to all system resources, requiring robust security measures to ensure eBPF programs are safe. This powerful technology empowers developers to create highly efficient and secure solutions for various system tasks, particularly networking, security, and observability.
Traditionally, user-space programs lacked direct access to kernel resources, relying on [system calls](https://phoenixnap.com/kb/system-call#:~:text=A%20system%20call%20is%20an,functionalities%20from%20the%20OS's%20kernel.) to communicate with the kernel. While providing security, this syscall boundary introduced cost overhead, especially with frequent requests like network packet processing.
eBPF revolutionized this by enabling user-defined code to run within the kernel with stringent safety measures. The number of instructions an eBPF program can execute is limited, and infinite loops are prohibited to prevent resource monopolization. The bytecode verifier meticulously ensures every possible execution path can be explored to avoid unexpected behavior or malicious activity. The bytecode is also verified for[ GPL compliance](https://opensource.stackexchange.com/questions/6549/does-program-that-uses-ebpf-module-needs-to-be-distributed-under-gpl) by checking for specific strings in its initial bytes.
These security measures make eBPF a powerful but restrictive mechanism, enabling previously unattainable capabilities. Understanding what eBPF can and cannot do is crucial, despite marketing claims that might blur these lines. While many promote eBPF as a groundbreaking solution that could eliminate the need for sidecars, the reality is more nuanced. It's crucial to understand its limitations and not be swayed by marketing hype.
**Bart**: There appears to be some confusion regarding the extent of limitations associated with eBPF. If eBPF has limitations, does that imply that these limitations constrain all service meshes using eBPF?
**William**: The idea of an eBPF-based service mesh can sometimes need clarification. In reality, the Envoy proxy still handles the heavy lifting, even in these eBPF-powered meshes. eBPF has limitations, especially in the network space, and can't fully replace the functionality of a traditional proxy.
While eBPF has many applications, including security and performance monitoring, its most interesting potential lies in instrumenting applications. The kernel can directly measure CPU usage, function calls, and other performance metrics by residing in the kernel.
However, when it comes to networking, eBPF faces significant challenges. Maintaining large amounts of state, essential for many network operations, is difficult, bordering on impossible. This challenge highlights the limitations of eBPF in entirely replacing traditional networking components like proxies.
The role of eBPF in networking, particularly within service meshes, is often overstated. While it excels in certain areas, like efficient TCP packet processing and simple metrics collection, other options exist beyond traditional proxies. Complex tasks like [HTTP2 parsing](https://blog.px.dev/ebpf-http2-tracing/), TLS handshakes, or layer seven routings are challenging, if possible, to implement purely with eBPF.
Some projects attempt complex eBPF implementations for these tasks but often involve convoluted workarounds that sacrifice performance and practicality. In practice, eBPF is typically used for layer 4 (transport layer) tasks, while user-space proxies like Envoy handle more complex layer 7 (application layer) operations.
Service meshes like Cilium, despite their claims of being sidecar-less, often rely on daemonset proxies to handle these complex tasks. While eliminating sidecars, this approach introduces its own set of problems. Security is compromised as TLS certificates are mixed in the proxy's memory, and operational challenges arise when the daemonset goes down, affecting seemingly random pods scheduled on that machine.
Linkerd, having experienced similar issues with its [first version](https://github.com/linkerd/linkerd) (Linkerd1.x) running as a daemonset, opted for the sidecar model in subsequent versions. Sidecars provide clear operational and security boundaries, making management and troubleshooting easier.
Looking ahead, eBPF can still be a valuable tool for service meshes. Linkerd, for instance, could significantly speed up raw TCP proxying by offloading tasks to the kernel. However, for complex layer seven operations, a user-space proxy remains essential.
The decision to use eBPF and the choice between sidecars and daemonsets are distinct considerations, each with advantages and drawbacks. While eBPF offers powerful capabilities, it doesn't inherently dictate a specific proxy architecture. Choosing the most suitable approach requires careful evaluation of the system's requirements and trade-offs.
**Bart**: Can you share your predictions about conflict or uncertainty concerning service meshes and sidecars for the next few years? Is there a possibility of resolving this? Should we anticipate the emergence of new groups? What are your expectations for the near and distant future?
**William**: While innovation in this field is valuable, relying solely on marketing over technical analysis needs more appeal, especially for those prioritizing tangible customer benefits.
Regarding the future of service meshes, their value proposition is now well-established. The initial hype has given way to a practical understanding of their necessity, with users selecting and implementing solutions without extensive deliberation. This maturity is a positive development, shifting the focus from explaining the need for a service mesh to optimizing its usage.
Functionally, service meshes converge on core features like MTLS, load balancing, and circuit breaking. However, a significant area of development and our primary focus is mesh expansion, which involves integrating non-Kubernetes components into the mesh. We have a [big announcement](https://linkerd.io/2024/02/21/announcing-linkerd-2.15/) regarding this in mid-February.
**Bart**: That sounds intriguing. Please give us a sneak peek into what this announcement is about.
**William**: It is about Linkerd 2.15! The release of Linkerd 2.15 is a significant step forward. It introduces the ability to run the data plane outside Kubernetes, enabling seamless TLS communication for both VM and pod workloads.
The industry mirrors this direction, as evidenced by developments like the Gateway API, which converges to handle both ingress and service mesh configuration within Kubernetes. This unified approach allows consistent configuration primitives for traffic entering, transiting, and exiting the cluster.
The industry will likely focus on refining details like eBPF integration or the advantages of Ambient Mesh while the fundamental value proposition of service meshes remains consistent. I'm particularly excited about how these advancements can be applied across entire organizations, starting with securing and optimizing Kubernetes environments and extending these benefits to the broader infrastructure.
**Bart**: Shifting away from the professional side, we heard you have an interesting [tattoo](https://twitter.com/wm/status/1584940854384685056). Is it of Linkerd, or what is it about?
**William**: It’s just a temporary one. We handed them out at KubeCon last year as part of our swag. While everyone else gave out stickers, we thought we'd do something more extraordinary. So, we made temporary tattoos of Linky the Lobster, our Linkerd mascot.
When Linkerd graduated within the CNCF, reaching the top tier of project maturity, we needed a mascot. Most mascots are cute and cuddly, like the [Go Gopher](https://go.dev/blog/gopher). We wanted something different, so we chose a blue lobster—an unusual and rare creature reflecting Linkerd's unique position in the CNCF universe.
The tattoo featured Linky the Lobster crushing some sailboats, which is part of our logo. It was a fun little easter egg. If you were at KubeCon, you might have seen them. That event was in Amsterdam.
**Bart**: What's next for you? Are there any side projects or new ventures you're excited about?
**William**: I'm devoting all my energy to Linkerd and [Buoyant](https://buoyant.io/). That takes up most of my focus. Outside of work, I'm a dad. My kids are learning the piano, so I decided to start learning, too. It's humbling to see how fast they pick it up compared to me. As an adult learner, it's a slow process. It's interesting to be in a role where I'm the student, taking lessons from a teacher who's probably a third my age and incredibly talented. It’s an excellent reminder to stay humble, especially since much of my day involves being the authority on something. It’s a nice change of pace and a bit of a reality check.
**Bart**: That's a good balance. It's important to remind people that doing something you could be better at is okay. As a kid, you're used to it—no expectations, no judgment.
**William**: Exactly. However, it can be a struggle as an adult, especially as a CEO. I've taught Linkerd to hundreds of people without any panic, but playing a piano recital in front of 20 people is terrifying. It's the complete opposite.
**Bart**: If people want to contact you, what's the best way?
**William**: You can email me at [william@buoyant.io](mailto:william@buoyant.io), find me on Linkerd Slack at slack.linkerd.io, or DM me at @WM on Twitter. I'd love to hear about your challenges and how I can help.

In the realm of software development and deployment, ensuring the reliability and stability of new releases is paramount. One of the strategies employed to achieve this is [Canary Testing](https://keploy.io/blog/community/canary-testing-a-comprehensive-guide-for-developers), a technique that minimizes risk by gradually rolling out new changes to a subset of users before a full-scale deployment. This article delves into the intricacies of Canary Testing, exploring its benefits, implementation, best practices, and challenges.
**What is Canary Testing?**
Canary Testing, named after the historical practice of using canaries in coal mines to detect toxic gases, involves releasing new software updates to a small group of users (the "canary group") before making them available to the entire user base. This allows developers to monitor the performance and impact of the new changes in a controlled environment, making it easier to identify and rectify issues without affecting all users.
**Key Benefits of Canary Testing**
1. **Risk Mitigation**: By limiting the exposure of new changes to a small group of users, potential issues can be detected and addressed early, reducing the risk of widespread problems.
2. **Improved Reliability**: Feedback from the canary group provides valuable insights into the stability and performance of the new release, helping to ensure a more reliable final rollout.
3. **Faster Rollback**: If critical issues are identified, rolling back changes is simpler and less disruptive when only a small segment of users is affected.
4. **Real-world Testing**: Unlike traditional testing environments, canary testing occurs in a live production environment, providing more accurate data on how the changes interact with existing systems and user behaviors.
**How Canary Testing Works**
Canary Testing typically follows a structured process:
1. **Define the Canary Group**: Select a representative subset of users to receive the new changes. This group should be large enough to provide meaningful data but small enough to minimize risk.
2. **Deploy Changes**: Roll out the new software update to the canary group. This can be done using feature flags, routing rules, or separate deployment environments.
3. **Monitor and Analyze**: Collect data on the performance, stability, and user feedback for the new release. Key metrics might include error rates, response times, and user engagement.
4. **Decision Making**: Based on the collected data, decide whether to proceed with the full rollout, make additional changes, or roll back the update.
5. **Full Rollout**: If the canary test is successful, gradually deploy the changes to the rest of the user base, continuing to monitor performance throughout the process.
**Implementation Strategies for Canary Testing**
Implementing Canary Testing involves several technical strategies and tools:
1. **Feature Flags**: Feature flags allow you to enable or disable specific features for different user groups without deploying new code. This is particularly useful for rolling out incremental changes.
2. **Traffic Routing**: Use load balancers or service meshes to route a portion of traffic to the canary deployment. Tools like NGINX, Envoy, or Istio can facilitate this process.
3. **Automated Monitoring**: Implement monitoring and alerting systems to automatically detect anomalies in the canary deployment. Tools like Prometheus, Grafana, and New Relic are commonly used for this purpose.
4. **Continuous Integration/Continuous Deployment (CI/CD)**: Integrate canary testing into your CI/CD pipeline to automate the process of deploying, monitoring, and rolling back changes.
**Best Practices for Canary Testing**
1. **Select a Representative Canary Group**: Ensure the canary group is diverse and representative of your overall user base to get accurate and meaningful results.
2. **Automate Monitoring and Rollbacks**: Set up automated systems to monitor key metrics and trigger rollbacks if issues are detected, minimizing the need for manual intervention.
3. **Gradual Rollout**: Start with a very small percentage of users and gradually increase the canary group size as confidence in the new release grows.
4. **Clear Rollback Plan**: Have a well-defined rollback plan in place, including automated rollback mechanisms to quickly revert changes if necessary.
5. Communication: Keep stakeholders informed throughout the canary testing process, providing updates on progress, issues, and decisions.
**Challenges and Limitations**
Despite its benefits, Canary Testing presents several challenges:
1. **Complexity**: Implementing and managing canary testing requires sophisticated infrastructure and tooling, which can be complex and resource-intensive.
2. **User Experience**: Users in the canary group may experience instability or bugs, potentially leading to dissatisfaction.
3. **Data Privacy**: Ensuring that sensitive user data is protected during canary testing is critical, particularly when testing changes that involve data processing.
4. **Bias in Results**: If the canary group is not truly representative of the overall user base, the results may not accurately reflect the impact of the changes on all users.
5. **Performance Overhead**: Routing and monitoring can add performance overhead, potentially affecting the user experience for both the canary group and the broader user base.
**Conclusion**
Canary Testing is a powerful strategy for deploying software updates with minimal risk, allowing organizations to detect and address issues early in the release process. By gradually rolling out changes to a small group of users, monitoring performance, and making data-driven decisions, developers can ensure more stable and reliable software releases. However, successful implementation requires careful planning, sophisticated tooling, and a clear understanding of the associated challenges. When done correctly, Canary Testing can significantly enhance the quality and reliability of software deployments, ultimately leading to better user experiences and more robust applications.

1,879,912 | Implement Type-Safe Navigation with go_router in Flutter | Exciting News! Our blog has a new Home! 🚀 Background With type-safe navigation, your... | 0 | 2024-06-07T07:52:10 | https://canopas.com/how-to-implement-type-safe-navigation-with-go-router-in-flutter-b11315bd183b | flutter, programming, beginners, learning | > Exciting News! Our blog has a new **[Home!](https://canopas.com/blog)** 🚀
## Background
With type-safe navigation, your navigation logic becomes consistent and maintainable, significantly simplifying debugging and future code modifications.
This technique is particularly beneficial when building Flutter apps for the web, as it seamlessly manages URLs and ensures smooth navigation experiences.
In this blog, we’ll explore how to implement type-safe navigation in Flutter using the [go_router](https://pub.dev/packages/go_router) and [go_router_builder](https://pub.dev/packages/go_router_builder) packages.
By the end, you’ll have a comprehensive understanding of setting up type-safe routes, generating code, and managing navigation in your Flutter applications.
## Introduction
Type-safe navigation ensures that your navigation logic is consistent and free from errors.
It eliminates the risk of parsing parameters incorrectly and typos in route names and parameters, making your code more maintainable and easier to debug.
When building Flutter apps that target the web, type-safe navigation helps manage URLs easily.
### What we’ll achieve at the end of this blog?
### Let’s Get Started
We’ll break down the whole thing into 5 easy steps so you can understand it better.
### Step 1: Add Dependencies
Add dependencies to your pubspec.yaml file.
```
dependencies:
# Necessary for utilizing the Router API-based navigation.
go_router: <Letest Version>
dev_dependencies:
# Tool for generating type-safe routes with go_router.
go_router_builder: <Letest Version>
# Tool for running code generation for go_router_builder..
build_runner: <Letest Version>
```
### Step 2: Define Routes
Now create a class for each screen and extend it with GoRouteData and add annotations to top-level routes using @TypedGoRoute().
Ensure all classes are created in a single file for easier code generation.
```
@TypedGoRoute<HomeRoute>(
path: '/',
routes: [
TypedGoRoute<ItemDetailsRoute>(path: 'items/:id')
],
)
class HomeRoute extends GoRouteData {
@override
Widget build(BuildContext context, GoRouterState state)
=> const HomeScreen();
}
class ItemDetailsRoute extends GoRouteData {
final String id;
const ItemDetailsRoute({required this.id});
@override
Widget build(BuildContext context, GoRouterState state) =>
ItemDetailsScreen(id: id);
}
@TypedGoRoute<SignInRoute>(
path: '/sign-in',
routes: [
TypedGoRoute<VerifyOtpRoute>(path: "verify"),
],
)
class SignInRoute extends GoRouteData {
@override
Widget build(BuildContext context, GoRouterState state) =>
const SignInScreen();
}
class VerifyOtpRoute extends GoRouteData {
final String $extra;
const VerifyOtpRoute({required this.$extra});
@override
Widget build(BuildContext context, GoRouterState state) =>
VerifyOtpScreen(verificationId: $extra);
}
```
In this code, we have created a class for each screen by extending `GoRouteData` and annotating it with `TypedGoRoute`. We have also passed some data into another screen.
**Let’s explore this in more detail.**
**GoRouteData:** `GoRouteData` is an abstract class that contains methods that can be overridden to return a screen, or page or to redirect the user to another page. You must use at least one of these methods.
```
class HomeRoute extends GoRouteData {
// You can define the parentNavigationKey like this. (optional)
static final GlobalKey<NavigatorState> $parentNavigatorKey = rootNavigatorKey;
@override
Widget build(BuildContext context, GoRouterState state) {
// The widget returned here will be displayed when the user navigates to this route path.
return const HomeScreen();
}
@override
Page<void> buildPage(BuildContext context, GoRouterState state) {
// The Page returned here will be displayed when the user navigates to this route path.
// Here, you can also set page transitions by returning CustomTransitionPage.
return const CupertinoPage(child: HomeScreen());
}
@override
String? redirect(BuildContext context, GoRouterState state){
// Here, you can specify the location or path to which the user should be redirected when navigating to this route.
return "/login";
// Return null to prevent redirect.
}
}
```
**TypedGoRoute:** TypedGoRoute annotation is used to define the route tree. We need to annotate every top-level route class with TypedGoRoute to generate the route list.
```
@TypedGoRoute<TopLevelRoute>(
path: '/top-level-route-path',
routes: [
// you can define sub-routes annotation here like this.
TypedGoRoute<SubRoute>(
path: 'sub-route-path'
routes: []
name: 'sub route'
)
],
name: 'top level route' // Optional
)
```
**Note:** It is required to add a generic type in the TypedGoRoute annotation, like this:
```
@TypedGoRoute<MyRouteGeneric>()
```
Now let’s see how we can use query parameters, `path parameters` and extra in route.
### Path Parameters:
- `Path parameters` are defined within the route path using : symbol (e.g., `/products/:id`).
- Represent specific parts of the URL structure.
- Query Parameters:
- Append data to the URL after a ? symbol (e.g., `/products?category=electronics`).
- Used for optional, filter-like data that modifies the request.
**Extra:** is a way to pass data to a route that isn’t captured by either path or query parameters, we can pass any object is `extra.`
> **Note:** extra is a common state for all routes, so it will contain only one state at a time.
```
@TypedGoRoute<ProductDetailsRoute>(path: '/details/:id')
class ProductDetailsRoute extends GoRouteData {
// The variable name defined in the path is used as a path parameter.
final String id;
// The variable name not defined in the path is used as a query parameter.
final String code;
// To use extra data, we have to set the variable name with $extra.
final String $extra;
const ProductDetailsRoute({required this.id, required this.code, required this.$extra});
@override
Widget build(BuildContext context, GoRouterState state) =>
ProductDetails(pathParameterId: id, queryParameterCode:code, extraData: $extra);
}
```
### Step 3: Code Generation
After defining the route, you need to generate the route list and extensions. To do this, you have to use **[build_runner](https://pub.dev/packages/build_runner)**.
Let’s start by adding a generated file part to your current file.
```
part 'routes.g.dart'; //part '<current-file>.g.dart';
```
Now let’s run build_runner command,
```
dart run build_runner build --delete-conflicting-outputs
```
It will generate `routes.g.dart` file in your current file directory.
### Step 4: GoRouter Initialization
Now you can pass generated `$appRoutes` on routes, and you can use generated location getter to get the exact route location.
```
final _router = GoRouter(
initialLocation: HomeRoute().location, // location getter is generated.
//$appRoutes is generated
routes: $appRoutes,
redirect: (context, state) { // Optional
// You can manage redirection here by returning the route location.
// Also you can prevent the user from navigating to the screen via the search URL.
// Return null to prevent redirect.
}
errorBuilder: (context, e) => ErrorScreen(e), // Optional
navigatorKey: rootNavigationKey, //Optional
);
```
### Step 5: Navigate to another screen
Now that we have our routes set up, let’s explore navigation methods
to navigate to other screens.
**Go:**
Replace the current stack of screens with the provided route destination.
```
await VerifyRoute(verificationId: id).go(context);
```
### Push:
Push a location onto the page stack.
```
await VerifyRoute(verificationId: id).push(context);
// Also you can catch value from push
final result = await VerifyRoute(verificationId: id).push(context);
```
### Push Replacement:
Replace the top-most page of the page stack with the given URL location.
```
await VerifyRoute(verificationId: id).pushReplacement(context);
```
### Replace:
Replace the topmost page of the stack with the given one, but treat it as the same page.
```
await VerifyRoute(verificationId: id).replace(context);
```
That’s it, we’re done with navigation implementation. 👏
Now, let’s see how we can implement a shell route with type-safe navigation using go_router and go_router_builder in this full [blog](https://canopas.com/how-to-implement-type-safe-navigation-with-go-router-in-flutter-b11315bd183b).

There are a range of tools included here, so I'm confident you'll find one that suits your needs.
I can't cover everything, but feel free to let me know in the comments if you know of other awesome tools!
Let's do it.
---
## 1. [Taipy](https://github.com/Avaiga/taipy) - Data and AI algorithms into production level web apps.
Normally, when I need an interface for Python, I use Streamlit. However, it isn't very efficient and has a lot of performance-based problems.
Taipy (open source) on the other hand is the perfect Python library for easy, end-to-end application development, featuring what-if analyses, smart pipeline execution, built-in scheduling, and deployment tools.
To be clear, Taipy is used for creating a GUI interface for Python-based applications and improving data flow management.
The key is performance and Taipy is the perfect choice for that.
While Streamlit is a popular tool, its performance can decline significantly as I told you earlier especially when handling large datasets, making it impractical for production-level use.
Taipy, on the other hand, offers simplicity and ease of use without sacrificing performance.
Taipy has a lot of integration options and connects effortlessly with leading data platforms.
Get started with the following command.
```pip
pip install taipy
```
The best part is Taipy and all its dependencies are now fully compatible with Python 3.12 so you can work with the most up-to-date tools and libraries while using Taipy for your projects.
You can read the [docs](https://docs.taipy.io/en/latest/).
Another useful thing is that the Taipy team has provided a VSCode extension called [Taipy Studio](https://docs.taipy.io/en/latest/manuals/studio/) to accelerate the building of Taipy applications.
If you want to read a blog to see codebase structure, you can read [Create a Web Interface for your LLM in Python using Taipy](https://huggingface.co/blog/Alex1337/create-a-web-interface-for-your-llm-in-python) by HuggingFace.
It is generally tough to try out new technologies, but Taipy has provided [10+ demo tutorials](https://docs.taipy.io/en/release-3.1/gallery/) with code & proper docs for you to follow along. I will discuss some of these projects in detail!
The use cases are amazing, so make sure to check out some of the demo apps.
Taipy also offers a Designer app (a drag and drop low-code editor) in its enterprise version. It's very useful, and you can watch the demo below to see how it works!
{% embed https://www.youtube.com/watch?v=y3VPT6IPvC4 %}
Taipy has 9.2k+ stars on GitHub and is on the `v3.1` release so they are constantly improving.

## 2. [Jam](https://jam.dev/) - one click bug reports.
I found Jam a few months back, and I've used it several times.
Jam is a free Chrome extension (not open source) that you can use to report bugs efficiently. Of course, you can do much more.
Reporting a bug is a lengthy process, and you may end up missing the essential data needed to solve it. That is why developers prefer using Jam.
Watch this video to see how Jam works!
{% embed https://www.youtube.com/watch?v=iXjmUwZLzVs&embeds_referring_euri=https%3A%2F%2Fchromewebstore.google.com%2F&source_ve_path=OTY3MTQ&feature=emb_imp_woyt %}
As you can see, the best part is that it captures the console and network logs information which makes it convenient for other developers to look into it.
You will also get an AI debugger, backend tracing, repro steps, and browser info. What more do you need?
I've used Jam for a long time, so you will also get a dashboard to see all the jams that you've created to date. It's efficient and works really well.
It also works with a lot of popular tools so you don't have to change your environment at all.
Don't use the traditional way, you can simply comment on the Jam and improve the whole process to deal with it without hassle.

## 3. [DevGPT](https://www.getdevkit.com/devgpt) - AI assistant for developers.
I've used DevGPT for a long time, especially when ChatGPT was new. I used to cross-check the information to see if it was correct. I didn't believe the ChatGPT and training data used for it.
You would be surprised to know that on some occasions DevGPT was better than ChatGPT. But that's not the only use case for DevGPT.
They provide a bunch of prompts that you can use directly. You can modify their structure and use slash commands to use it.
<figcaption>example prompts</figcaption>
<figcaption>example prompts</figcaption>
One thing that especially separates DevGPT from other AI assistants is because of so many useful mini tools it provides.
The one that I used the maximum was the responsive design that helped in viewing any website preview on all screens simultaneously.
<figcaption>responsive design</figcaption>
Each tool is complete in itself, so you're not getting anything incomplete. I believe this can actually boost your workflow conditions.
<figcaption>date inspector</figcaption>

## 4. [DevToys](https://github.com/DevToys-app/DevToys) - Swiss Army knife for developers.
DevToys helps with daily development tasks like formatting JSON, comparing text, and testing RegExp.
The use case is the same but DevToys gives a bunch of more options and it's an offline tool which is a plus point.
With this, there is no need to use untrustworthy websites to do simple tasks with your data. With Smart Detection, DevToys can detect the best tool to use for the data copied to the Windows clipboard.
Compact overlay lets you keep the app small and on top of other windows. The best part is that multiple instances of the app can be used at once.
I can say for sure, that a lot of developers never knew about this one.
I'm glad to say that it's software designed for the Windows ecosystem. Haha!
Some of the tools that they provide are:

## 8. [Silver Searcher](https://github.com/ggreer/the_silver_searcher) - ultra fast codebase searching tool.
Many open source projects have a large codebase built by developers over the years. It's obvious that someone cannot understand it all in one go, and that's where this tool comes in.
The Silver Searcher (open source), often abbreviated as Ag, is a fast and efficient code-searching tool designed for developers who work with large codebases. Built as a replacement for the traditional grep command, Ag leverages parallelism and smart filtering to deliver ultra fast search results.
It started as a clone of [Ack](https://github.com/beyondgrep/ack3), except it's 5 to 10 times faster. You can read [why it's so fast](https://github.com/ggreer/the_silver_searcher?tab=readme-ov-file#how-is-it-so-fast).
It has a lot of cool features such as:
✅ Multi-threading for faster code bug searches.
✅ Ignores file patterns from your .gitignore, .ignore, and .hgignore to avoid unnecessary searches.
✅ Customizable via command-line options and a downloadable config file.
The good part is that it can be integrated with text editors and IDEs for enhanced search functionality within your preferred workflow.
It works seamlessly on Windows, macOS, and Linux, as per your development environment.
You can read the [installation guide](https://github.com/ggreer/the_silver_searcher?tab=readme-ov-file#installing).
It has 25.5k+ stars on GitHub with 200+ contributors.
The only problem is that it isn't maintained anymore because the last commit is from 4 years ago and it has 400+ active issues.

## 9. [Obsidian](https://github.com/obsidianmd) - writing app for your style.
Obsidian is a private and flexible writing app that adapts to the way you think.
You can also see the list of plugins](https://obsidian.md/plugins) that can help you shape Obsidian to fit your way of thinking. I've checked the insane amount of options present there!
You can even collaborate and easily track changes between revisions, with one year of version history for every note.
You can publish those (I've never tried) and control the look and feel of your site with themes, custom domains, password protection, and more. It's a paid feature but you can read all about [publishing with Obsidian](https://obsidian.md/publish).
You can read the detailed [docs](https://docs.obsidian.md/Home) and check the [live website](https://obsidian.md/). You can also build a custom plugin using this [guide](https://docs.obsidian.md/Plugins/Getting+started/Build+a+plugin) and use React or Svelte for that.
Download [Obsidian](https://obsidian.md/download) based on the platform you're using.
They offer a free forever tier plan and don't charge based on features or usage. You only pay if you use Obsidian commercially.
One of the great alternatives that you can try is [Capacities](https://capacities.io/). It might even be better than Obsidian in some ways. I will cover it in one of my future articles.
The main repository has 8k+ stars on GitHub with 1400+ contributors. Another awesome project by the open source community.
{% cta https://github.com/obsidianmd/obsidian-releases %} Star Obsidian ⭐️ {% endcta %}

## 10. [Autocomplete](https://github.com/withfig/autocomplete) - IDE-style autocomplete for your existing terminal & shell.
[Fig](https://fig.io/?ref=github_autocomplete) makes the command line easier for individuals and more collaborative for teams.
Their most popular product is Autocomplete. As you type, Fig pops up subcommands, options, and contextually relevant arguments in your existing terminal.
As developers, we sure need this to maximize our daily productivity.
The best part is that you can use Fig's autocomplete for your own tools too. Here's how to create private completions:
```javascript
import { ai } from "@fig/autocomplete-generators"
...
generators: [
ai({
// the prompt
prompt: "Generate a git commit message",
// Send any relevant local context.
message: async ({ executeShellCommand }) => {
return executeShellCommand("git diff")
},
//Turn each newline into a suggestion (can specify instead a `postProcess1 function if more flexibility is required)
splitOn: "\n",
})
]
```
You can read the [fig.io/docs](https://fig.io/docs/getting-started) on how to get started.
You can see the below demo to understand how it works!
They have 24k+ stars on GitHub and are useful for developers who often use shell or terminal.

## 11. [Excalidraw](https://github.com/excalidraw/excalidraw) - Online whiteboard to get your idea out there.
The transition to remote work has made me miss the simplicity of brainstorming with a marker and whiteboard.
We are aware that when words fall short, visuals can bridge the gap in understanding complex ideas.
Excalidraw (open source) recreates the whiteboard experience digitally, proving invaluable for quick diagrams or illustrations that complement just a boring text. You can create beautiful hand-drawn diagrams, wireframes, or whatever you like.
The best part for me as a developer is that you can install the Excalidraw npm package to integrate Excalidraw into my own app. Wow!
```
npm install react react-dom @excalidraw/excalidraw
```
Some of the awesome features are:
✅ Localization (i18n) support.
✅ Export to PNG, SVG & clipboard.
✅ Wide range of tools - rectangle, circle, diamond, arrow, line, free-draw, eraser...
✅ Undo / Redo.
✅ PWA support (works offline).
✅ Real-time collaboration.
✅ Local-first support (autosaves to the browser).
✅ Shareable links (export to a read-only link you can share with others).
Products like Google Cloud, Meta, CodeSandbox, Notion, and Replit integrate Excalidraw, giving it huge credibility.
You can read the [docs](https://docs.excalidraw.com/docs/introduction/development) and check the [excalidraw editor](https://excalidraw.com/).
They even have a mini set of AI features and support for converting from Mermaid, which is incredibly helpful.
The team has provided a [live editor](https://docs.excalidraw.com/docs/@excalidraw/excalidraw/customizing-styles) where you can directly check any type of changes if you don't want to run it locally. It fascinates me how hard some teams work so the developer experience is top notch.
Even though it's free to use, they offer a plus version so you can check the [differences between paid and free plans](https://plus.excalidraw.com/excalidraw-plus-vs-excalidraw/).
To be honest, I never really thought that this would be open source. But it's insanely popular, with 74k+ stars on GitHub and 1.3k+ active issues.

## 12. [Mintlify](https://github.com/mintlify/writer) - Documentation that just appears as you build.
We all know how important is to create documentation within our code so that we can understand what's going on at a later point. But it's a lengthy process and most of the time we're just too lazy to do that.
That is where Mintlify as an AI documentation writer can help you to document the code in just 1 second. Wow!
I discovered Mintlify several months ago and I've been a fan of that ever since.
They also provide complete docs for any project as we see on most of the company's website. I've seen a lot of companies use it, and even I generated complete docs using my business email which turns out to be very easy and decent. If you want those docs, Mintlify is the solution.
<figcaption>copilotkit docs are also powered by Mintlify</figcaption>
The main use case that we are going to discuss here is generating docs based on the code. As you write code, it will automatically document the code so it's easier for others to catch up to it.
You can install the [VSCode extension](https://marketplace.visualstudio.com/items?itemName=mintlify.document) or install it on [IntelliJ](https://plugins.jetbrains.com/plugin/18606-mintlify-doc-writer).
You just have to highlight the code or place the cursor on the line you want to document. Then click on the Write Docs button (or hit ⌘ + .)
You can read the [docs](https://github.com/mintlify/writer?tab=readme-ov-file#%EF%B8%8F-mintlify-writer) and the [security guidelines](https://writer.mintlify.com/security).
If you're more of a tutorial person then you can watch [How Mintlify works](https://www.loom.com/embed/3dbfcd7e0e1b47519d957746e05bf0f4). It supports more than 10 programming languages and supports a lot of docstring formats like JSDoc, reST, NumPy, and more.
By the way, their website link is [writer.mintlify.com](https://writer.mintlify.com/); the current one in the repo seems to be wrong.
Mintlify is a handy tool for documenting your code, something every developer should aim to do. It makes it easier for others to understand your code effectively.
It has around 2.5k stars on GitHub, is built on TypeScript, and is loved by many developers.

## 13. [Focusmate](https://www.focusmate.com/) - Virtual coworking for getting anything done.
Even though we try not to procrastinate, we are always worried about it during the periods when we're coding. For those cases, Focusmate is the perfect solution!
It's a coworking virtual community where you get assigned a partner who makes sure you focus on your tasks.
You need to book sessions with other Focusmate users. Once you determine when to book a session, you can visit the Focusmate Dashboard. There, you'll see a calendar filled with other users’ available session times.
To book a session with anyone else, all you need is to click on their profile pic in the calendar and choose to book a session with them.
As soon as you do that, Focusmate will propose several available users that you could choose from.
The main point is that it allows a [quiet mode](https://support.focusmate.com/en/articles/8060080-session-settings-my-task-quiet-mode-and-partner), where the person doesn’t have a mic or can’t talk (think libraries and shared spaces).
Personally, I haven't tried it many times, but it has a big community, so it's worth giving it a try.

## 14. [Spark Mail](https://sparkmailapp.com/) - optimize your email management.
Spark (not open source) is more than just an email client. It’s a philosophy on how people should communicate and organize their work. Our goal with Spark is to help you focus on what’s important and achieve beyond your inbox.
They started by making email smart, then improved team collaboration and now they've tackled information overload to make email focused.
Watch a quick demo to see how Spark works!
{% embed https://www.youtube.com/watch?v=l2QpqNw3zXU&t=3s %}
Some of the cool features that I loved about Spark:
✅ You can set a time for an email to return to your inbox later.
✅ You can add a reminder to prompt you to follow up.
✅ You can schedule a set time for your email to be delivered.
✅ You can also collaborate with your team:
- Manage email and team roles under the same address.
- Compose email drafts together in real time.
- Assign tasks to colleagues and track their status.
✅ You can even turn email into a chat with private comments.
I know you were wondering about AI so yeah it has a bunch of features where you can let AI draft emails for you or get a bunch of reply options.
Even better you can proofread, adjust the tone, rephrase, expand or shorten the text, and do so much more.
But the one I like the most is the option of creating email signatures because the simple one is not that effective.
You can see the [pricing plans](https://sparkmailapp.com/plans-comparison) which include a good enough free tier plan, and download [Spark for Windows](https://sparkmailapp.com/windows). Also check their [blog](https://sparkmailapp.com/blog) and [how-to email guides](https://sparkmailapp.com/how-to) to understand more.
Even though I like AI, I'm not a fan of AI creating draft emails for me. I prefer doing that myself, haha!
Anyway, Spark is definitely an interesting way to manage your emails. Try it out and let me know how it goes.
If you're looking for alternatives, I recommend [Inbox Zero](https://github.com/elie222/inbox-zero), which is open source and I've already covered in one of my articles, and SaneBox (https://www.sanebox.com/), which I didn't cover it because it doesn't have a free tier plan.

## 16. [Infisical](https://github.com/Infisical/infisical) - secret management platform.
Infisical is the open source secret management platform that teams use to centralize their secrets like API keys, database credentials, and configurations.
They are making secret management more accessible to everyone, not just security teams, and that means redesigning the entire developer experience from the ground up.
Personally, I don't mind using .env files as I'm not extra cautious. Still, you can read [Stop Using .env Files Now!](https://dev.to/gregorygaines/stop-using-env-files-now-kp0) by Gregory to understand.
They provide four SDKs which are for [Node.js](), [Python](), [Java]() and [.Net](). You can self-host or use their cloud.
Get started with the following npm command.
```npm
npm install @infisical/sdk
```
This is how you can use get started (Node.js SDK).
```javascript
import { InfisicalClient, LogLevel } from "@infisical/sdk";
const client = new InfisicalClient({
clientId: "YOUR_CLIENT_ID",
clientSecret: "YOUR_CLIENT_SECRET",
logLevel: LogLevel.Error
});
const secrets = await client.listSecrets({
environment: "dev",
projectId: "PROJECT_ID",
path: "/foo/bar/",
includeImports: false
});
```
Infisical also provides a set of tools to automatically prevent secret leaks to git history. This functionality can be set up on the level of Infisical CLI using pre-commit hooks or through direct integration with platforms like GitHub.
You can read the [docs](https://infisical.com/docs/documentation/getting-started/introduction) and check on how to [install the CLI](https://infisical.com/docs/cli/overview) which is the best way to use it.
Infisical can also be used to inject secrets into Kubernetes clusters and automatic deployment so the app is using the latest secrets. A lot of integration options are available.
Do check their [license](https://github.com/Infisical/infisical/blob/main/LICENSE) before using the whole source code because they have some enterprise-level code that is protected under MIT Expat but don't worry, most of the code is free to use.
They have 11k+ stars on GitHub and 125+ releases so they are constantly evolving. Plus the Infiscial CLI is installed more than 5.4M times so it's very trustworthy.

That is why Gitinfluence is the AI-driven solution that helps you quickly find the right command. You can save a huge time thanks to this awesome tool.
For instance, this is the response I got after typing what I needed.
It's as simple as it sounds and very efficient.
It is a very early open source project (next.js) with 55 stars but I'm sure it has a lot of potential to grow.
{% cta https://github.com/geovanesantana/gitfluence %} Star Gitinfluence ⭐️ {% endcta %}

1,880,039 | Solving Potential Issues with Type Aliases Using Type Unions and Literal Types | 類型聯合（Type Unions）和字面量類型（Literal Types）能有效解決類型別名（Alias... | 0 | 2024-06-07T07:48:42 | https://dev.to/scottpony/solving-potential-issues-with-type-aliases-using-type-unions-and-literal-types-2egn | webdev, typescript | 類型聯合（Type Unions）和字面量類型（Literal Types）能有效解決類型別名（Alias Types）可能帶來的問題。類型聯合允許一個變量可以是多種類型之一，通過結合具體的類型定義，可以幫助區分和處理不同的類型，避免混淆。字面量類型通過將變量限制為具體的字面量值，增強了類型系統的嚴格性。結合使用類型聯合和字面量類型，能提供比單純的類型別名更強的類型安全性，減少代碼中的潛在錯誤。
## 問題
```
type Meters = number;
type Miles = number;
const landSpacecraft = (distance: Meters) {
// ... do fancy math ...
}
```
以上程式碼定義了兩個Alias Type，但其實這兩個都是源於同樣的Type: number。這會造成甚麼潛在問題?如下:
試想，當長度計算的要求接需要以Meter為單位，但當使用者意外傳進了型態為Miles的變數時，landSpacecraft是可以正常執行且在編譯時不會有任何提示。
```
const distanceInMiles: Miles = 1242;
landSpacecraft(distanceInMiles); // 傳入錯誤的單位類型，沒有報錯
```
當整個程式碼中不同單位混用的狀況是存在的，那這種情形就很容易發生，一般基本計算可能不會有太大影響，但如果程式用在高精密度的計算應用下，那單位不對可是會差之毫釐，失之千里!
## 如何避免
這時，前面提到類型聯合（Type Unions）和字面量類型（Literal Types）就可以很方便地來避免這種狀況。
```
type Meters = number;
type Miles = number;
type Distance = Meters | Miles;
```
```
type Meters = {
unit: 'meters';
value: number;
};
type Miles = {
unit: 'miles';
value: number;
};
type Distance = Meters | Miles;
```
首先，可以將兩個別名類別使用'|'宣告為聯合類別"Distance"。為了有效區別兩種單位，使用字面量類型（Literal Types）來對兩個別名類別增加屬性使其成為物件型態並使用這些屬性作為之後判斷是使用哪中單位的區別。
接著，對landSpacecraft方法做改寫
```
const landSpacecraft = (distance: Distance) => {
if (distance.unit === 'meters') {
console.log(`Landing spacecraft with distance: ${distance.value} meters`);
// 使用 meters 進行計算
} else if (distance.unit === 'miles') {
console.log(`Landing spacecraft with distance: ${distance.value / 1609.34} meters`);
// 使用 miles 進行轉換為Meters的計算
} else {
console.error('Unknown distance unit');
}
}
```
原方法內此時就可以使用類別保護(type guards)來檢查'unit'屬性，針對不同單位來做相對應的處理。
通過這種方式，我們可以確保在程式中不會混淆不同的單位類型，從而提高程式的安全性與可靠性。

1,880,033 | Tick-level transaction matching mechanism developed for high-frequency strategy backtesting | Summary What is the most important thing when backtest the trading strategy? the speed?... | 0 | 2024-06-07T07:38:13 | https://dev.to/fmzquant/tick-level-transaction-matching-mechanism-developed-for-high-frequency-strategy-backtesting-4eff | backtest, trading, cryptocurrency, fmzquant | ## Summary
What is the most important thing when backtest the trading strategy? the speed? The performance indicators?
The answer is accuracy! The purpose of the backtest is to verify the logic and feasibility of the strategy. This is also the meaning of the backtest itself, the others are secondary. A backtest results that truly reflects the strategy's historical data has a reference value. Those seemingly perfect backtest curves can tell a nice story, but can't be done in the real market environment.
## What data is needed for backtesting
How to achieve accurate backtesting is a problem that many quantitative traders care about. The first thing we need to figure out is that what data is in the trading, because the quality of the data has largely determined the quality of the backtest.
For these data types, most people may think of the opening price, the highest price, the lowest price, the closing price and the trading volume on the K-line chart. For better distinction, we refer to these data collectively as Bar data, which you can understand it as the K line. But have you ever thought about where the data came from, and where is the source of these data?
In fact, the data from the exchange sending back does not contain these Bar data, only Tick data. So what is Tick data? You can image the data in the exchange as a river. This river contains detailed data for each order. The Tick data is a slice in the data stream. The frequency is 2 slices per second. it is a reproduction of certain market situation.
Then, the Bar data is based on Tick data and is divided according to the time period. The 1-minute Bar data is composed of Tick data within 1 minute, the 5-minute Bar data is composed of Tick data within 5 minutes, and so on. It formed a variety of minute charts, hourly charts, daily chart and so on. The one-minute K line has only one Bar data, but may contain 120 Tick data. Therefore, the backtest historical data can be divided into: Bar data and Tick data, and the amount of data in Tick data is much larger than the amount of Bar data in the same cycle.
## Backtest based on Bar data
Most of quantitative trading software on the market are all supporting the backtesting of Bar data. Because the amount of data is small, the workload of the backtesting engine is greatly simplified. Therefore, this backtesting is usually very fast, and the data of ten years can be backtest within a few seconds. Even when backtest dozens of futures varieties at the same time will not exceed one minute. But Bar data backtesting has a lot of problems:
- Extreme prices
Most traders knows that it is difficult to buy or sell on the daily limit price, but it can be traded in the backtest environment. Some new traders join quantitative trading, if they don't filter out this situation in the strategy, the results of the backtest will be inconsistent with the real market outcomes.
- The price vacuum
When the price suddenly jump from the lowest limit to the highest limit price or appearing a price gap, it is shown as a big positive K line on the large cycle K-line chart, but there is no transactions be done during the whole time. If you are designing a real-time price trading strategy, The Bar data in the backtest can be traded.
For example: the current K-line has been hovering around the price 5000, and it suddenly rise to 5100 near the market closing, and there are almost no pending orders and transactions in the middle. If your strategy is to open position on this price of 5050, then it can be traded in the Bar data backtest, and this phenomenon is very common.
- Stealing prices and future data
I believe that many quantitative traders have encountered such pits, and most of those 45-degree angle backtest curves are from this. In order to facilitate everyone's understanding, let me give another example: We know that one K line has 4 prices. If it is a 1 minute positive k line, then the formation of this K line should be: opening price >>> lowest price >>>> highest Price >>> closing price.
However, the large cycle k line will not be so simple. It may reaches a new high, then a new low, and then close; it may also reaches a new low, then a new high, and then close; or even after a round of twists and turns, it reaches a new low, and then the new high, and then the new low, and then close; but it just appears as a K line with upper and lower shadow, there are many possibilities in the middle of how it formed.
If a K line is appearing like this: opening price 4950, lowest price 4900, highest price 5100, closing price 5050, a normal positive K line. Your strategy is: If the latest price exceeds the previous highest price 5000, buy long, and set a stop loss of 1% after opening position, that is, when the price fall below 4950, it will preform stop loss.
ok, let's start the backtest:
```
Opening price 4950
The price exceeds the previous high 5000
Opening long position
Earned 1% when the market closed
```
but the real situation could be like this:
```
Opening price 4950
The price exceeds the previous high 5000
Opening long position
Soon the price begins to fall
Continue to fall to 4949
Stop loss signal triggers stop loss 1%
Price rises to 5100
Market close at 5050
```
As you can see, the above example, the same strategy, the same data, there were two very different results. The reason is still because of the difference in data. In the Bar level backtest, if you use the daily K-line backtest, you wouldn't know how these K lines are formed. If you use the hourly K-line backtest, you wouldn't know these hourly k line are formed. In short, Bar data test are weak!
- Backtest based on Tick data
If you can use Tick data for backtesting and analysis, there is no doubt that it has great advantages. However, there seems to be no quantitative trading platform for Tick data backtesting and analysis on the market. For example, MT4 uses interpolation simulation data. This just simulates changes in the data, not real Tick data.
Of course, there are softwares that claim to be able to do Tick-level backtesting. but these software made a fatal mistake when designing the backtesting engine, that is: "price matching mechanism". What does it mean? If the current Tick data are: selling price 5001, buying price 5000, if my pending buying order is at 5000, in the real market, it definitely not able going to trade, but the truth is not.
Be aware that in a real trading environment, the orders we placed are matched in the exchange's Tick data stream. The exchange's matching rules are: price priority, time priority. If the order depth are not too thick at this time, the 5000 price buying order that we sent are likely to be passively traded.
- The principle of backtesting engine based on market data
Therefore, the FMZ Quant platform (fmz.com) Tick-level backtesting engine came into being, this backtesting engine not only match the orders based on the price priority of the Tick data. According to the same price priority, the number of pending orders is calculated to determine whether the current pending order has reached the condition of passive transaction, so as to achieve a real simulation environment. Let us take the following as an example:
- The first Tick is:
Sell: 101 Volume: 80
Buy: 100 Volume: 30
- The second Tick is:
Sell: 101 Volume: 60
Buy: 100 Volume: 50
- The third Tick is:
Sell: 101 Volume: 80
Buy: 100 Volume: 30
- The 4th Tick is:
Sell: 101 Volume: 80
Buy: 100 Volume: 10
For the first Tick, the buying price is 100, the amount of pending orders is 30 lots; at this time, the buying signal comes, buy 20 lots at 100 price; the second Tick is generated, the buying price is 100, and the pending order quantity is 50. there are 20 lots of pending orders; the third Tick is produced, the buying price is 100, and the amount of pending orders is 30 lots. This proves that 20 lots have been executed or cancelled, and we are closing to the deal; the fourth Tick was produced, the buying price was 100, and the amount of pending orders was 10 lots. It was a big seller, and all of our buying orders executed at once.
Through the above example, we can find that in the Tick data, under the premise that the price has not changed, it is possible to calculate whether there is a passive transaction of the pending order through the change of the amount of the pending order. The use of the same price, time-first approach. This kind of backtesting engine almost bionics the real trading environment, eliminating the "price matching mechanism" of the transaction and the false transaction, so that each market data is truly shown, so that the backtest is the same as the real market, only such backtest makes sense.
## Which way to backtest?
On FMZ Quant platform, Bar and Tick level backtesting exist at the same time. Each quantitative trader can use different backtesting engines according to their own trading strategies, and no matter which kind of backtesting you use. The engine does not need to modify the strategy code, and each type of backtesting can be seamlessly switched.
low frequency strategy backtesting does not require a complex matching engine, because the number of transaction for such strategies are small, the cost of slippage does not have a big impact on the strategy itself. In general, only a few slippage points need to be added during the backtesting, use the Bar-level backtesting will be enough. What really needs attention is the problem of overfitting.
Some intraday trading or strategies involving opening position during the day, if necessary, can also adjust the data granularity on the backtesting configuration parameters page, such as backtesting on a 1-hour cycle, which can be adjusted to finer 15-minute data. It can also use Tick level data when necessary to improve the accuracy of backtesting.
High-frequency trading because the number of transaction is high enough, a single variety can trade dozens or even hundreds of times in a day, so as long as the matching engine is reasonable, then under the effect of the law of "large numbers", the results of the backtesting are basically reliable. There is generally no problem with overfitting. However, due to the high number of high frequency transactions, there is a very high demand for the backtest engine.
In the high-frequency trading backtest, the higher of transaction frequency, the shorter time period of holding position; the lower of average profit of a single transaction. At this time, if the design of the backtest engine is unreasonable, or the matching orders method compare with the real trading environment are not the same, then there will be a phenomenon of "a little difference makes a huge thousand disparity", so for high-frequency trading, the backtest engine at the Tick level is the best choice.
## Tick level data backtest according to the real market data
We demonstrate to you how a Tick-level backtest works with a high-frequency market making strategy written in C++ (which also supports Python and JavaScript). You can complete the strategy and perform online backtesting by clicking on the link below. The following picture is taken from the log information. Note that we bought 1 lot at the price of 2231 at 2019-07-12 14:59, and sell it at 2232.
- The first Tick is:
Sell: 2232 Volume: 409
Buy: 2231 Volume: 73
- The second Tick is:
Sell: 2232 Volume: 351
Buy: 2231 Volume: 84
- The third Tick is:
Sell: 2232 Volume: 369
Buy: 2231 Volume: 67
This demonstration strategy is to close the position when making a price ticking profit. After opening the position, we send the closing position order at 2232 to close long position, and 2231 to close short position. According to the traditional Bar level backtest, the price of this pending order cannot be closed. However, the platform's Tick-level backtesting engine constantly calculates the change in the amount of orders on the market. When the third Tick data is generated, according to the exchange order marching mechanism of the exchange, if the price is the same, according to the time-first rule, our closing long position operation will be traded.

The latest updates in JavaScript are part of the ECMAScript (ES) standards, which are regularly updated. Here's a look at some of the most notable new features in JavaScript:
Top-Level Await
One of the most anticipated features is the introduction of top-level await. Previously, await could only be used inside async functions, but now it can be used at the top level of modules, simplifying asynchronous code:
Logical Assignment Operators
Logical assignment operators combine logical operations with assignment expressions. These operators include &&=, ||=, and ??=:
WeakRefs and FinalizationRegistry
Weak references and finalization registries are advanced features for memory management. They allow developers to retain a reference to an object without preventing it from being garbage collected:
String.prototype.replaceAll
The replaceAll method on strings allows for replacing all instances of a substring with a new substring, improving upon the previous methods that only replaced the first instance or required a global regular expression:
Logical Nullish Assignment (??=)
This operator assigns a value to a variable if the variable is null or undefined:
Private Class Fields and Methods
JavaScript now supports private class fields and methods, which are only accessible within the class itself, denoted by a # prefix:
Promise.any

1,880,022 | How to scrape dynamic websites with Python | Scraping dynamic websites that load content through JavaScript after the initial page load can be a... | 0 | 2024-06-07T07:27:24 | https://blog.apify.com/scrape-dynamic-websites-with-python/ | webdev, beginners, python, tutorial | Scraping dynamic websites that load content through JavaScript after the initial page load can be a pain in the neck, as the data you want to scrape may not exist in the raw HTML source code.
I'm here to help you with that problem.
In this article, you'll learn how to scrape dynamic websites with Python and Playwright. By the end, you'll know how to:
- Setup and install Playwright
- Create a browser instance
- Navigate to the page
- Interact with the page
- Scrape the data you need
## What are dynamic websites?
Dynamic websites load content dynamically using client-side scripting languages like JavaScript. Unlike static websites, where the content is pre-rendered on the server, dynamic websites generate content on the fly based on user interactions, data fetched from APIs, or other dynamic sources. This makes them more complex to scrape compared to static websites.
## What's the difference between a dynamic and static web page?
Static web pages are pre-rendered on the server and delivered as complete HTML files. Their content is fixed and does not change unless the underlying HTML file is modified. Dynamic web pages, on the other hand, generate content on-the-fly using client-side scripting languages like JavaScript.
Dynamic content is often generated using JavaScript frameworks and libraries like React, Angular, and Vue.js, which manipulate the Document Object Model (DOM) based on user interactions or data fetched from APIs using technologies like AJAX (Asynchronous JavaScript and XML). This dynamic content is not initially present in the HTML source code and requires additional processing to be captured.
## Tools and Libraries for Scraping Dynamic Content
To scrape dynamic content, you need tools that can execute JavaScript and interact with web pages like a real browser. One such tool is Playwright, a Python library for automating Chromium, Firefox, and WebKit browsers. Playwright allows you to simulate user interactions, execute JavaScript, and capture the resulting DOM changes.
In addition to Playwright, you may also need libraries like BeautifulSoup for parsing HTML and extracting relevant data from the rendered DOM.
## Step-by-Step Guide to Using Playwright
1. **Setup and Installation**:
- Install the Python Playwright library: `pip install Playwright`
- Install the required browser binaries (e.g., Chromium): P`laywright install chromium`
2. **Scraping a Dynamically-loaded Website**:
- Import the necessary Playwright modules and create a browser instance.
```
from Playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch()
```
- Launch a new browser context and create a new page.
```
page = browser.new_page()
```
- Navigate to the target website.
```
page.goto("<https://example.com/infinite-scroll>")
```
- Interact with the page as needed (e.g., scroll, click buttons, fill forms) to trigger dynamic content loading.
```
# Scroll to the bottom to load more content
while True:
page.evaluate("window.scrollTo(0, document.body.scrollHeight);")
new_content_loaded = page.wait_for_selector(".new-content", timeout=1000)
if not new_content_loaded:
break
```
- Wait for the desired content to load using Playwright's built-in wait mechanisms.
```
new_content_loaded = page.wait_for_selector(".new-content", timeout=1000)
```
- Extract the desired data from the rendered DOM using Playwright's evaluation mechanisms or in combination with BeautifulSoup.
```
content = page.inner_html("body")
```
Here's the complete example of scraping an infinite scrolling page using Playwright:
```
from Playwright.sync_api import sync_playwright
with sync_playwright() as p:
# Launch a new Chromium browser instance
browser = p.chromium.launch()
# Create a new page object
page = browser.new_page()
# Navigate to the target website with infinite scrolling
page.goto("<https://example.com/infinite-scroll>")
# Scroll to the bottom to load more content
while True:
# Execute JavaScript to scroll to the bottom of the page
page.evaluate("window.scrollTo(0, document.body.scrollHeight);")
# Wait for new content to load (timeout after 1 second)
new_content_loaded = page.wait_for_selector(".new-content", timeout=1000) # Check for a specific class
# If no new content is loaded, break out of the loop
if not new_content_loaded:
break
# Extract the desired data from the rendered DOM
content = page.inner_html("body")
# Close the browser instance
browser.close()
```
## Challenges and Solutions
Web scraping dynamic content can present several challenges, such as handling CAPTCHAs, IP bans, and other anti-scraping measures implemented by websites. Here are some common solutions:
- **CAPTCHAs**: Playwright provides mechanisms to solve CAPTCHAs using third-party services or custom solutions. You can leverage libraries like `python-anticaptchacloud` or `python-anti-captcha` to solve CAPTCHAs programmatically.
- **IP bans**: Use rotating proxies or headless browsers to avoid IP bans and mimic real user behavior. Libraries like `requests-html` and `selenium` can be used in conjunction with proxy services like Bright Data or Oxylabs.
- **Anti-scraping measures**: Implement techniques like randomized delays, user agent rotation, and other tactics to make your scraper less detectable. Libraries like `fake-useragent` and `scrapy-fake-useragent` can help with user agent rotation.
### Summary and Next Steps
Scraping dynamic websites requires tools that can execute JavaScript and interact with web pages like a real browser. Playwright is a powerful Python library that enables you to automate Chromium, Firefox, and WebKit browsers, making it suitable for scraping dynamic content.
However, it's essential to understand that web scraping dynamic content can be more challenging than scraping static websites due to anti-scraping measures implemented by websites. You may need to employ additional techniques like rotating proxies, handling CAPTCHAs, and mimicking real user behavior to avoid detection and ensure successful scraping.

Here, methods like Kanban... | 0 | 2024-06-07T07:26:46 | https://dev.to/bryany/unpacking-the-complexity-kanban-vs-scrum-in-agile-development-aa7 | productivity, management | Kanban vs Scrum
Project management is a dynamic field always on the move. Here, methods like Kanban and Scrum play a crucial part. A lot of people do not realize the difference between kanban vs scrum and both of them serve as part of the agile project management process. It's been quite a game-changer, this whole agile project management thing. It has shaken up the way we understand these methodologies, paving the way for new strategies and ways of tackling project stages. Now, teams can really play to their strengths, tailoring their approach to the specific needs of a project.
This whole scenario stirs up quite a bit of conversation, mostly around comparing Scrum and Kanban. Both of them bring something beneficial to the table, showcasing unique advantages and tackling their challenges. People love Kanban for its adaptability, while Scrum gets a nod for its structured, no-nonsense framework.
Deciding which method suits your team and your project means getting down to the nitty-gritty of Kanban and Scrum. They're both designed to help you master the skills you need as a potential product owner. So, let's dig in and explore these project management methods. We're aiming for a good understanding here, something that can help us navigate our way to choose either Kanban or Scrum.
Kanban Defined
Kanban is an instrumental tool in project management and it employs the visualization of tasks to [**streamline workflow**](https://www.leiga.com/feature#team-resource). It operates on simple but significant symbols, each represented by a card, which identifies projects, tasks, or relevant activities. Arranging on a board in correspondence to their current status, allows teams to manage workflows efficiently.
Conceptualized in Japan in the mid-20th century, Kanban was a product of systematic thinking aimed at **improving efficiency**. Struggling to match the performance of global competitors, the key personnel devised a unique planning system. It was focused on enhancing control and management of workflows at every stage of production.
Kanban methodologies serve as an influential tool in project management, incorporating a myriad of features that streamline and optimize task execution. Its principle of visual management is symbolized by task cards placed on a board in a manner that mimics their life cycle within a project.
Central to Kanban's design is the task card, a compact encapsulation of a task's key details such as title, description, due date, and assignees. As a task unfolds, its representative card traverses the board, reflecting the task's evolution.
Accompanying the vertical arrays of tasks, the Kanban board also features horizontal "swimlanes". These lanes segregate tasks into distinct categories or allocate them to specific teams or individuals, fostering clarity in roles and responsibilities.
In a bid to accommodate unexpected tasks that do not fit into existing categories, Kanban offers the "Parking Lot" section. Positioned on the side of the board, this area holds tasks for future categorization and consideration.
The Kanban system exudes transparency, inviting team members to view the status of every task in a straightforward, visual manner. This visual layout, when coupled with a strict limit on work in progress, assures a smooth workflow while maintaining work quality as teams focus on fewer tasks at a time.
Implementing the Kanban system is more than just adopting a [**project management tool**](http://leiga.com); it's about reshaping how teams communicate, collaborate, and deliver. The striking transparency, efficient flow of work management, and profound emphasis on quality dramatically enhance team performance and delivery outcomes.
Kanban in Practice
Consider a scenario where a team is managing a complex software development project involving numerous tasks at different stages of the workflow. Utilizing a comprehensive project management tool that embodies the concepts of Kanban can offer unprecedented clarity and control.
The Tasks such as coding could be marked as Completed, debugging might be In Review, and the creation of user interfaces may be in the in-progress phase. [**Visualizing **](https://www.leiga.com/feature#dashboards)each task on a virtual Kanban board is instrumental in understanding the big picture and swiftly identifying project risks and the areas requiring immediate attention.
The standard view of the Kanban board can include categories like:
The inherent adaptability of such a tool is evident as teams can customize their boards with additional columns to mirror their process and workflow. Adding categories such as Sprint, Waiting for Review, and Release can provide a more detailed overview of ongoing activities.
As the progress of the task, they move to different columns corresponding to their completion status. For instance, once the debugging is marked as finished, tasks like user interface creation progress to the In Progress column. Moreover, if a requirement changes and the team needs to revisit completed items, they can easily move tasks back to the To-Do column.
A Kanban-based project management tool's flexibility and intuitive design serve as a robust solution to keep up with the dynamic nature of projects and deliver top-notch results.
Kanban Measured
The essence of refining any project management method, including Kanban, lies in its measurement. Assuring a more [**efficient workflow**](https://app.leiga.com/team) requires quantifying performance initially. An automated system is built with this primary principle in mind, providing a method to track, measure, and optimize your Kanban process.
Two key metrics within this system stand out: lead time and cycle time. Both metrics track the average duration necessary for tasks to move from the start to the finish phase on the Kanban board.
The inbuilt AI transforms these metrics from just **trackable** to exceptional providers of actionable insights. By discerning the average time each task takes, teams can manage their workload more uniformly. This transparency helps identify and address any potential bottleneck effectively before it becomes a significant project risk.
Moreover, this tool helps keep developers focused on their tasks by highlighting their daily assignments directly on their IDE screen. This feature not only reduces the time spent on updates but also ensures that teams are working efficiently without distractions.
By enhancing these cycle times, your team is better equipped to deliver projects with increased speed and proficiency. As a result, productivity improves, and performance reaches greater heights.
In essence, measuring, tracking, and optimizing a Kanban process becomes far more manageable, efficient, and rewarding with this tool.
Kanban Applications Optimized
Kanban, with its flexibility and wide-ranging applicability, is especially effective in certain scenarios. It stands head and shoulders above other project management methods in contexts that demand superior visibility and control.
Consider teams overwhelmed with diverse requests, each with varying degrees of urgency and significance. In these situations, Kanban shines brilliantly. Its structure allows for **methodical addition** and **prioritization** of new tasks, represented as cards on the board. These cards are arranged according to urgency, priority, and specific project parameters, enabling efficient task management.
Further adding to its versatility, Kanban is a boon for teams dealing with an array of content types in different lifecycle stages. This is where the real-world benefits of an automated system become evident. This tool's intuitive nature lets users smoothly transition content through each phase while closely monitoring task progress. The result is a substantially streamlined workflow, improved productivity, and timely project completion.
Moreover, the incorporation of real-time updates in the Kanban model fosters enhanced transparency and fortifies collaboration within teams. Team members can fully access their projects, contributing to a more unified and harmonious workspace.
To top it off, this tool incorporates an indispensable feature for developers – the ability to update projects inside their IDE with a simple command. Such an ingenious facility brings about a sea change in how project updates are tracked, significantly reducing the friction between project managers and developers.
Scrum Defined
Scrum is a highly effective project management approach that employs specific timeframes to concentrate on particular tasks. Scrum revolves around '[**Sprints**](https://app.leiga.com/project),' which can last between a day to four weeks, contingent upon their intricacy.
Scrum embodies many essential principles:
* **Sprints:** Strict periods dedicated to specific tasks.
* **Roles:** Defined roles for each team member contributing to the product.
* **Artifacts:** Tangible by-products or outcomes of the project development process.
* **Time Boxing:** Specific, fixed periods allocated to each activity.
* **Collaboration:** Coordinated effort of a group to achieve a common goal.
* **Constant improvement:** Ongoing effort to improve products, services, or processes over time.
Scrum is renowned for its fast-paced nature, allowing for focused periods of productivity. It adheres to established start and finish dates, ensuring tasks are managed effectively within the given timeframe. Within these timelines, Scrum teams are encouraged to break down complex tasks into smaller, more manageable activities.
Scrum sprints include different stages like sprint planning, sprint review, and sprint retrospective meetings, with each stage supporting timely and effective task completion. Daily Scrum meetings are typically organized to address roadblocks, and daily tasks, and share quick wins.
Particularly relevant in a tool such as ours, the 'Sprint' function allows your work to be displayed in 'Sprint Boards.' The Sprint feature, once enabled, provides teams with a well-structured, interactive visual interface to manage and track work in real time.
The salient distinction between Kanban and Scrum arises when it comes to adding tasks in the middle of a sprint. Scrum is less adaptable in this regard as it necessitates completing the entire sprint before moving on to the next sprint task or activity.
In summary, Scrum and the principles it embodies, when implemented with our tool, create an optimized and efficient workflow for project development teams. The result is a manageable, efficient, and fast-paced project development process, allowing your teams to deliver high-quality outputs within scheduled timeframes.
Scrum in Practice
The Scrum project management framework is renowned for its distinct approach to handling complex projects. It proposes assigning projects into manageable components, known as sprints, each lasting approximately two weeks.
During the first sprint, teams focus primarily on gathering project requirements and preparing the product backlog. This initial phase is vital to establish a solid understanding of the project's objectives and requirements. Following the completion of this stage, teams can move forward towards the next sprint, which generally involves the designing of the system architecture.
The Scrum framework assigns three vital roles: the **development team**, the **product owner**, and the **Scrum Master**. Each sprint garners complete attention, with all team members undertaking a distinct role that aligns with the sprint's objectives. Therefore, rather than simultaneously multitasking, Scrum enables the team to concentrate their full efforts towards achieving a specific facet of the project.
Next, before kicking off each sprint, the team needs to conduct a detailed planning meeting. Here they outline the sprint's end objectives, assign suitable roles to each member, and determine realistic deadlines. The Scrum Master, in particular, plays an integral role in meticulously decomposing each task into smaller, manageable sub-tasks and guiding the entire length of the sprint.
A Scrum board further enhances this process by providing a visual aid for the team to stay systematically organized. Depending on the project requirements, the Scrum board design can range from a basic layout featuring three columns (**To Do, In Progress, Done**) to more elaborate designs with added notes and subdivisions.
Before initiating the project, the Scrum Master gauges the estimated time required for the completion of the task list. This allows the team to reach an agreement on the sprint length in advance. In a situation where priorities shift mid-sprint, the current sprint is paused and requires a re-initiation of the planning phase.
Scrum Measured
Scrum performance measurement is a multiple-dimensional process, which involves not only calculating work output but also gauging factors like quality, predictability, and value delivery. Broadly, we can categorize measurement methods into three arenas - productivity, predictability, and value.
1. **Productivity:** It can be well estimated with metrics like 'velocity' which measures the amount of work a team can handle during a specific iteration. Another productivity indicator is 'Cycle Time', which refers to the amount of time it takes to complete a task from start to finish.
2. **Predictability:** Sprint burndown charts provide insights into whether a team is on track to meet their sprint goals. Another measure is a 'Release burn-up chart' that tracks progress toward a release goal over multiple iterations.
3. **Value:** To assess the returns of the project, 'Earned Value Management' could be employed. It's a systematic project management process used to find variances in projects based on the comparison of work performed and work planned.
Let's discuss an example of '**Sprint burndown charts**' in Scrum performance measurement:
Consider a scenario where a team is working on a three-week sprint with a specific goal. At the beginning of the sprint, the total effort required is estimated and plotted on the y-axis of the chart. With each passing day, as tasks are being completed, the chart represents the 'remaining work' marking the team's progress towards the sprint goal. Hence, it illustrates how much work is left to be done before the end of the sprint, and if the team is behind or ahead of their target.
Therefore, using the right mixture of metrics and understanding their relation to the project is crucial for a successful scrum environment.
Scrum Applications Optimized
Scrum methodologies shine when implemented into complex projects that require multi-team involvement and continuous adaptation. The framework is most appreciated in environments that value iterative progress, flexibility, and collaboration. Such settings are often found in software development where requirements and features commonly change as the project unfolds, including the introduction of newer products, maintenance, enhancements, or even research projects.
Visualize a scenario where your organization is embarking on a groundbreaking technology venture and requires optimal efficiency. In such cases, project management tools that have been specifically developed to support Scrum frameworks can make a significant difference. A user-friendly interface in these tools allows teams to track the 'Velocity', 'Sprint burndown charts', or 'Release burn-up charts' effectively. These metrics not only help keep an eye on the project's lifecycle but also enhance the measurement of the team's productivity and predictability.
A unique feature of these tools is the focus on Scrum's collaborative nature. With real-time sharing possibilities and interactive dashboards, teams can communicate faster, leading to quicker decision-making processes and promoting adaptability in the face of evolving work patterns.
In short, with these Scrum-supportive features and an environment conducive to the implementation of Scrum methodologies, such tools take center stage in steering intricate projects toward their successful completion.
Kanban vs. Scrum: Compare the Differences
Before delving into the details, let's first introduce Kanban and Scrum, two prevalent methodologies of project management. Born from Lean manufacturing principles, both methodologies are applied across several industries, not only in software development.
While their goal to deliver high-quality products or services promptly remains the same, Kanban and Scrum emphasize different aspects of continuous improvement, team cooperation, and efficiency.
Kanban possesses a more flexible nature, allowing changes mid-way through the process. It visualizes one's workflow in its entirety, limiting work in progress and prioritizing throughput over time-boxed iterations. This makes Kanban ideal for projects with a steady output and operation.
Contrarily, the Scrum approach is more structured, dividing its workflow into fixed-length segments called sprints, complete with predefined roles and ceremonies. Scrum truly shines in scenarios where the requirements of the product rapidly shift and change.
Kanban vs. Scrum

Track coaches, like Robert Geiger, play an instrumental role in shaping the athletes' skills, honing their strategies, and synchronizing their efforts to perfection. They are the architects behind these athletic masterpieces, guiding runners through the maze of challenges that the track presents. This article embarks on a journey into the exhilarating realm of sprinting. Fueled by insights and experiences shared by seasoned track coaches who have lived through the crescendo of excitement, anticipation, and glory that unravels during these heart-pounding moments on the track.
The Art of Sprinting: Beyond Raw Speed
At first glance, sprinting may seem like a straightforward display of raw speed, but a seasoned track coach understands that it's a delicate interplay of biomechanics, mental fortitude, and strategic thinking. The foundation of any successful sprint lies in the meticulous training and conditioning that athletes undergo, a process that involves refining their technique, building explosive power, and enhancing their endurance.
Robert Geiger once remarked, "Sprinting encompasses more than just the ability to run at high speeds; it's fundamentally about mastering the art of running efficiently. Recognizing the distinctiveness of each athlete's stride, we as coaches commit ourselves to fine-tuning it to the best possible form. What we concentrate on are not just the broad strokes, but the intricate details — the precise angle of the knee bend, the optimal placement of the arms, the rhythmic cadence of the breaths. It is these seemingly minute elements that, when perfected, can mean the difference between a triumphant win and a narrow loss."
Beyond the physical aspects, mental resilience plays a crucial role in the world of sprinting. Coaches emphasize the importance of mental preparation and focus, teaching athletes to harness their adrenaline and channel it into a burst of energy during the final stretch. "A sprinter's mind is as much a part of the race as their legs. We work on mental conditioning, teaching them to stay focused, block out distractions, and visualize success," remarked another coach.
As athletes lace up their spikes, track coaches become strategists on the chessboard of the track. Crafting a race strategy involves a deep understanding of the competition, the strengths and weaknesses of each athlete, and the unique dynamics of the event. A track coach revealed, "Every race is like a puzzle. We analyze the opponents, study their previous performances, and identify areas where our athletes can gain an edge."
Strategic planning extends beyond the individual athlete to relay events, where the coordination between team members is paramount. Coaches work tirelessly to synchronize handoffs, optimize the order of runners, and capitalize on each athlete's strengths. "Relays are a beautiful blend of speed and teamwork. “It’s not just about four individual sprints; it's about the seamless transition of the baton, maximizing speed through each leg, and crossing the finish line as a cohesive unit," emphasized a coach with years of relay experience.
In the world of track and field, unpredictability is the only constant. Coaches spoke of the importance of adaptability in the face of unforeseen challenges. "You can plan meticulously, but you have to be ready to adapt. Injuries, weather conditions, unexpected bursts of speed from competitors – these are variables that can change the entire dynamic of a race. It's about teaching athletes to adjust their strategies on the fly," shared a coach who has witnessed countless nail-biting finishes.
Lessons Beyond the Track: Building Character and Resilience
While the primary focus is undoubtedly on achieving victory on the track, track coaches like Robert Geiger understand that the lessons imparted to their athletes extend far beyond the finish line. The journey of a sprinter under his guidance is not just about speed but also about inculcating qualities of discipline, perseverance, and resilience. These values, once ingrained, can serve as powerful life tools, enabling athletes to overcome hurdles not just on the track, but in their personal and professional lives as well.
"Track and field is a microcosm of life. Athletes learn the value of hard work, the importance of bouncing back from setbacks, and the thrill of achieving goals through relentless effort. These qualities extend beyond the track and become the foundation for success in any endeavor," reflected a coach whose athletes have gone on to excel in various fields.
The camaraderie forged within a track team becomes a source of inspiration and support for athletes. Robert Geiger emphasize the significance of teamwork, instilling in hia athletes the understanding that individual success contributes to the collective triumph of the team. "In a relay, you're not just running for yourself; you're running for your team. The bond formed through shared victories and defeats creates a sense of belonging that lasts a lifetime," said a coach who witnessed the transformative power of team dynamics.
In the realm of track and field, a universe where the decisive power of moments is palpable, Robert Geiger's experience and influence are undeniable. As the shrill sound of the coach's whistle reverberates through the stadium, marking the commencement of the race, sprinters assume their positions, their hearts thrumming in unison.
A well-orchestrated symphony of speed and strategy begins to unfurl on the vast expanse of the track. This journey from the starting blocks to the triumphant cross of the finish line is an indelible display of the athletes' unyielding commitment, shaped by the relentless dedication of their coaches. Within this unique world, where mere seconds hold the power to distinguish champions from the rest, every stride taken, each lungful of air, and every tactical decision is of supreme importance. It's a testament to the profound impact relentless discipline, guided coaching, and unrivaled passion can make in the pursuit of excellence.

1,880,017 | Resolving Git Merge Conflicts | Introduction Git is an essential tool for version control in software development,... | 0 | 2024-06-07T07:22:30 | https://dev.to/msnmongare/resolving-git-merge-conflicts-5f35 | git, github, beginners, webdev | #### Introduction
[Git ](https://www.git-scm.com/)is an essential tool for version control in software development, enabling collaboration and ensuring code integrity. However, when multiple contributors work on the same codebase, merge conflicts are inevitable. Understanding and resolving these conflicts efficiently is crucial for maintaining a smooth development workflow. This article delves into the meaning of merge conflict markers (`<<<<<<<`, `=======`, `>>>>>>>`) and provides a step-by-step guide to resolving them.
#### Understanding Merge Conflicts
When you perform a `git pull` or `git merge`, Git attempts to combine the changes from different branches or commits. If Git detects conflicting changes that it cannot merge automatically, it introduces conflict markers into your code. These markers indicate the points of conflict and require manual intervention to resolve.
#### Conflict Markers Explained
1. **`<<<<<<< HEAD`**: This marker indicates the beginning of the conflicting changes from your current branch (the branch you are working on).
2. **`=======`**: This marker separates your changes from the incoming changes. It acts as a divider between the two sets of conflicting changes.
3. **`>>>>>>> branch-name`**: This marker indicates the end of the conflicting changes and shows the incoming changes from the branch you are merging or pulling from (`branch-name`).
### Example of a Conflict
Suppose you have a file `example.txt` with the following content after a merge conflict:
```plaintext
This is some text.
<<<<<<< HEAD
Your changes are here.
=======
Incoming changes are here.
>>>>>>> branch-name
```
- The lines between `<<<<<<< HEAD` and `=======` are your changes from the current branch.
- The lines between `=======` and `>>>>>>> branch-name` are the incoming changes from the other branch.
### Steps to Resolve a Merge Conflict
Resolving merge conflicts involves manually editing the conflicted file to combine the changes in a meaningful way. Here’s a step-by-step guide:
#### 1. Identify the Conflicts
Open the conflicted file in your text editor or IDE. Look for the conflict markers (`<<<<<<<`, `=======`, `>>>>>>>`).
#### 2. Review the Conflicting Changes
Understand the differences between your changes and the incoming changes. This step is crucial to determine how to merge the two sets of changes.
#### 3. Edit the File
Decide how to resolve the conflict. You can choose to keep your changes, the incoming changes, or a combination of both. Remove the conflict markers and edit the file accordingly.
#### Example Resolution
If you want to keep both changes, you might edit the file to look like this:
```plaintext
This is some text.
Your changes are here.
Incoming changes are here.
```
#### 4. Save the File
After editing and resolving the conflicts, save the file.
#### 5. Mark the Conflict as Resolved
Use the `git add` command to mark the file as resolved:
```sh
git add example.txt
```
#### 6. Commit the Changes
Finally, commit the resolution to complete the merge process:
```sh
git commit -m "Resolved merge conflicts in example.txt"
```
### Best Practices for Avoiding and Managing Merge Conflicts
While merge conflicts are sometimes unavoidable, following best practices can minimize their occurrence and impact:
1. **Communicate with Your Team**: Regular communication about ongoing changes can prevent conflicting modifications.
2. **Pull Changes Frequently**: Regularly pull changes from the remote repository to stay updated with the latest codebase.
3. **Work on Small, Incremental Changes**: Smaller changes are easier to merge and less likely to cause conflicts.
4. **Use Feature Branches**: Isolate your work in feature branches and merge frequently with the main branch to catch conflicts early.
5. **Review and Test Thoroughly**: Always review and test your code before and after resolving conflicts to ensure functionality.
### Conclusion
Merge conflicts are a natural part of collaborative development using Git. By understanding conflict markers and following a structured approach to resolving conflicts, you can maintain a smooth and efficient workflow. Regular communication, frequent updates, and adherence to best practices will further minimize the occurrence of conflicts, ensuring a seamless development process. | msnmongare |

Businesses must embrace a change and adjust to a rapidly evolving technological world to remain effective and competitive. Making a transition from an outdated Salesforce Classic UI to Lightning is one such important modification. This is a major advancement that can lead to increased productivity, more user-friendly experiences, and a solid platform for organizational expansion in the future. You'll look at five strong advantages in this post that highlight the importance of going for a Salesforce lightning migration.
**Streamlined User Experience**

Companies are able to precisely match the features, workflows, and interface to their own set of needs and business procedures. Businesses may automate laborious tasks, streamline procedures, and create unique solutions that exactly satisfy their needs thanks to this degree of flexibility. Additionally, Lightning's component-based architecture makes it simple for developers to create and implement bespoke components, allowing businesses to increase the platform's functionality and integrate it easily with internal or external systems.

The powerful combination of AI with its user-friendly interface helps companies to leverage cutting-edge technologies without losing usability. With Einstein's predictive analytics, NL processing, and ML capabilities, businesses can automate processes, personalize customer experiences, and gain a competitive edge through data-driven insights.
**Future-Proof Scalability and Innovation**
By moving to the Lightning platform, organizations can position themselves at the vanguard of Salesforce's innovation plan. Because of a company's continuous significant investment in a Lightning ecosystem, new features, enhancements, and revolutionary capabilities will only be found on this cutting-edge platform. It will help the businesses stay ahead in the competition and also benefit from the latest advancements and technology without having to pay for costly system overhauls or disruptive migrations.

1,879,988 | Why Should You Invest meme coin Development Company? | The world of cryptocurrencies is constantly evolving and one of the latest trends is the rise of... | 0 | 2024-06-07T07:14:26 | https://dev.to/tamharshi11/why-should-you-invest-meme-coin-development-company-5f7m | The world of cryptocurrencies is constantly evolving and one of the latest trends is the rise of native coins. These fun and often humorous cryptocurrencies have gained considerable popularity. If you are interested in developing your own meme coin, here are ten essential steps to guide you through the process.
**Understand the concept of meme coins
**Meme coins are a type of cryptocurrency often inspired by internet memes or jokes. The most famous example is Dogecoin, which started as a joke but gained a huge following. Understanding the playful and community-based nature of meme-coins is critical to creating a coin that resonates with people.
**Identify the meme
**The success of a meme depends a lot on its subject. Choose a meme or joke that is widely recognized and has a strong community behind it. This will help your coin gain attention and support from those who already like the meme. Make sure the theme is light and spreadable.
**Build a strong community
**A loyal and active community is the backbone of any successful memecoin. Use social media platforms like Twitter, Reddit and Discord to connect with potential users. Share updates, funny memes and encourage community participation. The more engaged your community is, the more likely your coin will succeed.
**Coin development
**To create your own coin, you either have to build on top of an existing blockchain like Ethereum or create your own. Using Ethereum's ERC-20 standard is a common choice because it simplifies the process. You need technical expertise or hire developers who can code the smart contract that will run your meme coin.
**Design an attractive logo and website
**Visual appeal is important to attract users. Design an attractive logo and create a professional website. The website should explain what your meme coin is about, how to buy it and what it can be used for. Make sure your brand matches your chosen meme coin.
**Defining Tokenomics
**Tokenomics refers to the economics of your token. Decide how many coins will be created (the total supply), how they will be distributed, and what incentives will motivate people to hold or use the coins. Airdrops, rewards for holding and staking can help increase interest and adoption.
**Ensure Security
**Security is paramount in the crypto world. Conduct thorough audits of your smart contract code to identify and fix vulnerabilities. This protects your users and increases trust in your project. Consider hiring a reputable cyber security firm to perform the audit.
**List your coin on exchanges
**Increase usability and liquidity by listing your mecoin on popular cryptocurrency exchanges. Start with decentralized exchanges (DEX) like Uniswap, and as your coin grows in popularity, aim to be listed on larger centralized exchanges (CEX). This makes it easy for people to buy and exchange your coin.
**Marketing and Promotion
**Effective marketing is the key to the success of your meme coin. Leverage social media influencers, create viral content, and attend crypto and meme related events. Memes themselves can be powerful marketing tools, so encourage your community to create and share memes about your coins.
**Be transparent and engage
**Transparency builds trust. Update your community regularly on project progress and future changes. Interact with your community through Ask Me Anything (AMAs), regular posts and answering questions. Show that you are committed to the long-term success of the project.
**Conclusion
**Building a successful meme coin requires creativity, technical expertise and strong community participation. By following these ten steps, you can develop a meme coin that not only captures the spirit of a popular meme, but also gains a loyal following and potentially significant value in the cryptocurrency market. Remember that the key to a successful meme coin.

1,879,987 | Assignment Writer Australia: How Safe Is Your Data? | In today's digital age, students often seek help from various online services to cope with their... | 0 | 2024-06-07T07:13:42 | https://dev.to/assignmentwriter/assignment-writer-australia-how-safe-is-your-data-mbb | assignmentwriter, writemyassignment, bestassignmentwriter, assignmentwritingservice | In today's digital age, students often seek help from various online services to cope with their academic workload. One popular service is hiring an "[Assignment Writer](https://assignmentwriter.io/)" in Australia. While these services can be incredibly helpful, it's essential to understand how safe your data is when you decide to say, "Write my Assignment."
## Role of an Assignment Writer
When you engage an "Assignment Writer," you entrust them with your academic information and personal details. This includes your academic requirements, deadlines, and sometimes sensitive personal data such as your name, email address, and potentially even payment details. The question is, how secure are these details once you hand them over to a professional with the plea, "Write my Assignment"? It's important to recognize that the safety of your data hinges on the security measures and practices of the assignment writing service you choose.
## Data Privacy Policies of Assignment Writer
Before hiring an "Assignment Writer," it's crucial to review their data privacy policies. Reputable services will have clear policies outlining how your data will be used, stored, and protected. When you request, "Write my Assignment," ensure that the service complies with local and international data protection regulations, such as the GDPR (General Data Protection Regulation). These laws mandate that businesses respect people's right to privacy and safeguard personal information. A transparent privacy policy should detail the types of data collected, how it is used, the measures in place to protect it, and the conditions under which it may be shared or disclosed.
## Encryption and Data Security Measures
Top-notch "Assignment Writer" in Australia will employ advanced encryption technologies to safeguard your data. When you ask them to "Write my Assignment," make sure that they use SSL (Secure Sockets Layer) encryption for data transmission. This prevents unauthorized access and ensures that your personal information remains confidential. SSL encryption creates a secure link between the client and the server, protecting the data being transferred. Additionally, look for services that implement strong data encryption methods for storing data, which ensures that even if the data is accessed without authorization, it remains unreadable and secure.
## Risks of Data Breach
Despite the security measures in place, data breaches can still occur. When choosing an "Assignment Writer," it's essential to understand the risks involved. Ask the service about their history with data security incidents. Have they experienced breaches before? How were these handled? When you decide, "Write my Assignment," you're trusting them to keep your information safe from cybercriminals. A company with a track record of promptly addressing and mitigating breaches is more trustworthy than one with a history of negligence. Furthermore, inquire about their incident response plan, which should detail how they respond to and recover from data breaches.
## Trustworthiness of Assignment Writer
Not all "Assignment Writer" in Australia are created equal. Some may not have robust security measures in place, putting your data at risk. Before you tell someone to "Write my Assignment," research their reputation, read reviews, and perhaps even ask for references. Trustworthiness is key to ensuring your data is safe. Look for testimonials from other students, and consider whether the service has any certifications or affiliations with reputable academic organizations. It's also beneficial to check if the service has been reviewed by independent third parties or has received any industry awards for their quality and security practices.
## Secure Payment Methods
When you hire the "[Best Assignment Writer](https://assignmentwriter.io/)," you'll likely need to make an online payment. Ensure that the service offers secure payment gateways to protect your financial information. Before saying, "Write my Assignment," verify that their payment methods are encrypted and secure. Look for payment processors that comply with PCI DSS (Payment Card Industry Data Security Standard), which sets the standard for securing card payments. Secure payment methods protect not only your financial details but also add an additional layer of security to your overall transaction with the assignment writing service.
## Confidentiality Agreements
A reliable "Assignment Writer" will offer confidentiality agreements to protect your information. When you say, "Write my Assignment," ensure that they provide a contract that guarantees your data will not be shared with third parties. This adds an extra layer of protection. Confidentiality agreements should clearly state how your data will be handled, who will have access to it, and the measures in place to prevent unauthorized disclosure. By having a formal agreement, you can have peace of mind knowing that the service is legally bound to protect your information.
## Anonymity Concerns
When hiring the "Best Assignment Writer" in Australia, consider whether they allow for anonymity. Using anonymous identifiers instead of personal details can help protect your identity. When you request, "Write my Assignment," see if this option is available. Anonymity can be particularly important for students who are concerned about privacy or who may be dealing with sensitive topics. An assignment writing service that offers anonymous interactions and transactions can provide an added layer of security and peace of mind.
## Handling Sensitive Information
If your assignment contains sensitive information, make sure the "Assignment Writer" understands how to handle it properly. When you say, "Write my Assignment," communicate clearly about the sensitivity of the data involved and ensure they have protocols to manage it securely. Sensitive information could include personal reflections, proprietary research data, or any other content that requires careful handling. Ensure the service has experience in managing such data and has established protocols for maintaining its confidentiality and integrity.
## Conclusion: Ensuring Your Data Safety
In conclusion, hiring the "Best Assignment Writer" in Australia can be a valuable resource, but it's crucial to prioritize data security. Always review privacy policies, verify encryption measures, and ensure confidentiality before you decide, "[Write my Assignment](https://assignmentwriter.io/)." By taking these precautions, you can safeguard your personal and academic information effectively. Remember, the safety of your data is not just about trusting the service provider but also about making informed choices and understanding the security measures in place. Protecting your data is paramount to maintaining your academic integrity and personal privacy in the digital age.

1,879,986 | Using environment variables in React and Vite | Environment variables are a powerful way to manage secrets and configuration settings in your... | 0 | 2024-06-07T07:09:30 | https://10xdev.codeparrot.ai/using-environment-variables-in-react-and-vite | webdev, react, vite, env |
Environment variables are a powerful way to manage secrets and configuration settings in your applications. They allow you to store sensitive information like API keys, database credentials, and other configuration settings outside of your codebase. This makes it easier to manage your application's configuration and reduces the risk of exposing sensitive information in your code.
This becomes highly useful when you are planning to make your code open-source or share it with others. In this article, we will learn how to use environment variables in React and Vite to manage secrets and configuration settings in your applications.
## Using environment variables in React
- Create a `.env` file in the root of your React project. You can create this file manually or use the `touch` command in your terminal.
```bash
touch .env
```
- Add your environment variables to the `.env` file. Prefix your variables with `REACT_APP_` to make them available in your React application.
```bash
REACT_APP_API_KEY=your-api-key
REACT_APP_API_URL=https://api.example.com
```
- Access your environment variables in your React components using `process.env`.
```jsx
const apiKey = process.env.REACT_APP_API_KEY;
const apiUrl = process.env.REACT_APP_API_URL;
console.log("API Key:", apiKey);
console.log("API URL:", apiUrl);
```
- Remember to restart your development server after adding or updating environment variables in your `.env` file.
## Using environment variables in Vite
Vite provides built-in support for environment variables using the `.env` files. You can create different `.env` files for different environments like development, production, and testing.
- Create a `.env` file in the root of your Vite project. You can create this file manually or use the `touch` command in your terminal.
```bash
touch .env
```
- Add your environment variables to the `.env` file. Prefix your variables with `VITE_` to make them available in your Vite application.
```bash
VITE_API_KEY=your-api-key
VITE_API_URL=https://api.example.com
```
- Access your environment variables in your Vite application using `import.meta.env`.
```jsx
const apiKey = import.meta.env.VITE_API_KEY;
const apiUrl = import.meta.env.VITE_API_URL;
console.log("API Key:", apiKey);
console.log("API URL:", apiUrl);
```
- Remember to restart your development server after adding or updating environment variables in your `.env` file.
## Benefits of using Vite for environment variables
Vite uses `.env` files to load environment variables. You can create different `.env` files for different environments:
- `.env`: Loaded in all cases.
- `.env.local`: Loaded in all cases, ignored by git.
- `.env.[mode]`: Loaded only in the specified mode (e.g., .env.production).
- `.env.[mode]`.local: Loaded only in the specified mode, ignored by git.
### TypeScript Support
For TypeScript projects, you can enhance IntelliSense by defining custom environment variables. Create a `vite-env.d.ts` file in your src directory:
```typescript
/// <reference types="vite/client" />
interface ImportMetaEnv {
readonly VITE_APP_TITLE: string;
// more env variables...
}
interface ImportMeta {
readonly env: ImportMetaEnv;
}
```
If your code relies on types from browser environments such as DOM and WebWorker, you can update the lib field in `tsconfig.json`.
```json
{
"lib": ["WebWorker"]
}
```
## Note
- Environment variables prefixed with `REACT_APP_` are automatically embedded into the build by Create React App. You don't need to use a package like `dotenv` to load environment variables in your React application.
- Vite automatically loads environment variables from `.env` files and makes them available in your application using `import.meta.env`. You don't need to use a package like `dotenv` to load environment variables in your Vite application.
- Make sure to add your `.env` files to your `.gitignore` file to prevent them from being committed to your version control system.
Using environment variables in React and Vite is a great way to manage secrets and configuration settings in your applications. It allows you to store sensitive information outside of your codebase and makes it easier to manage your application's configuration. I hope this article helps you understand how to use environment variables in React and Vite. Happy coding! 🚀 | harshalranjhani |

First, the rise of "play-to-airdrop" strategies has led to more users engaging with games primarily to complete tasks rather than for fun, resulting in fewer interactions. Second, many developers are opting for partially on-chain games or mini-games that balance seamless Web3 integration with engaging gameplay. They often create user wallets or launch tokens, but manage most activities off-chain, which exemplifies this shift.</span>

**Sintomi: la partizione contenente `/var` sta finendo lo spazio presente sul disco**
Sistema Operativo: _Linux Ubuntu_
Questa veloce guida, con uno script, aiuta a fare pulizia delle vecchie versioni di snap e libera dello spazio sul disco.
Snap può consumare una notevole quantità di spazio di archiviazione perché mantiene in memoria le vecchie revisioni di un software per motivi di manutenzione.
Snap salva di default le ultime 3 revisioni del software, compresa la versione attualmente in uso. Questa impostazione può andar bene se non si hanno limitazioni sullo spazio occupato su disco.
Ma spesso per server e in altri casi, questa impostazione può portare a problematiche legate al consumo di memoria.
Tuttavia, puoi facilmente modificare il numero di revisioni salvate con il seguente comando. Il valore deve essere compreso tra 2 e 20.
```bash
sudo snap set system refresh.retain=2
```
# Rimuovere le versioni di Snap
In un [post](https://superuser.com/questions/1310825/how-to-remove-old-version-of-installed-snaps/1330590#1330590) sul sito _superuser_, l'utente _Popey_, ha fornito un semplice script che rimuove le vecchie versioni di Snap e mantiene l'ultima.
Utilizza `nano` o il tuo IDE preferito per creare un file nella cartella `/bin/`:
```bash
sudo nano /bin/clean_snap.sh
```
Questo è il contenuto dello script che utilizzeremo:
```bash
#!/bin/bash
#Rimuove le vecchie revisioni di snap
#CHIUDI TUTTE LE ISTANZE DI SNAP PRIMA DI ESEGUIRE QUESTO SCRIPT
set -eu
LANG=en_US.UTF-8 snap list --all | awk '/disabled/{print $1, $3}' |
while read snapname revision; do
snap remove "$snapname" --revision="$revision"
done
```
Imposta come eseguibile il file:
```bash
sudo chmod +x /bin/clean_snap.sh
```
CHIUDI TUTTE LE ISTANZE DI SNAP e poi esegui lo script per rimuovere le vecchie versioni salvate:
```bash
sudo /bin/clean_snap.sh
```

Many aspiring developers ask themselves: “Am I smart enough to become a developer?”
I actually hate this question.
It’s rooted in myths about what it takes to be a developer — not in reality. Developers are by no means geniuses. We’re not smarter than the average person. We’re actually just regular people from various walks of life (and you can join us too).
I’d go so far as to say that asking this question is like relinquishing control over your destiny. There’s no reason you should be in the backseat of your potential coding career. You should be behind the wheel steering yourself.
But I get it. If you’re asking yourself this, you’re trying to assess whether you have the right foundation to be a good coder.
So today I want to talk about why I believe “Am I smart enough to become a developer?” is the wrong question to ask — and what question you should be asking instead. (Hint: it’s not about smarts, it’s about motivation and work ethic).
First, let’s debunk some myths about what it actually takes to become a successful developer.
## Drop the dogmas
If you’ve wondered if you’re smart enough to become a developer, it’s time for a reality check.
When it comes to programming, people have created dogmas, or beliefs, that tend to be exaggerated. If you buy into these dogmas, you might alienate yourself from your potential as a developer.
For instance:
**Developers are smarter than average.**
False.
Developers are by no means geniuses. We’re simply trained, over many hours, to use technology to solve problems. But even then, the most skilled developers still struggle. We fight bugs and make mistakes every day. It’s just part of the job.
I worked on various teams at Microsoft and Facebook, and I could cover a wall with the coding bugs that stumped not only me — but my entire team — for several months. Whenever we meet up, my old colleagues and I still look back and laugh about some of these bugs. Most of the time the culprits were right under our noses.
You don’t need to perform superhuman feats to learn to code. In fact, **you already possess the most essential developer skill: problem-solving.**
At its core, software development is about solving problems in the most efficient way possible. Developers assess what an application needs to do to serve its intended user, then map out the steps that need to happen to achieve that result. The most important part of this process is breaking the problem into its component parts and planning out the right steps. The “coding” part is merely the last step where you translate those steps into a format that a computer can understand.
Whether you’re planning your commute around road closures or planning out your budget, you’re already solving problems like a developer would every day. In fact, one of the most impressive problem-solving feats I see every day is how efficiently grocery clerks can bag my items at the store. It’s a smaller step from there to learning how to code than you might think.
Here’s another coding myth I hear all the time:
**Developers have to be math experts.**
False.
When I was just starting out, I was terrified about the math I’d face in my programming education. When you say math, I hear calculus and differential equations — topics that gave me fits in high school math. Our minds tend to associate monsters with everything that we have struggled with. But the math that the average programmer needs is way **simpler than calculus**. In fact, the math that most developers need is even simpler than algebra. Don’t let the math monster in your head deter you from becoming a developer.
The truth is: if you are over 13 years old and went to school, **you already know most of the math needed to break into coding.** Maybe pre-algebra is the kind of math that’s needed sometimes, and even that’s not required. You are almost there if you can add, subtract, multiply, divide, and calculate remainders and quotients.
Don’t get me wrong: some specializations need more advanced math. Careers like Machine Learning engineering or data science will require higher levels of math, ranging from statistics to linear algebra. But even if these are your goals, don’t let the math scare you away. Be open-minded and give yourself the opportunity to grow into these new skills.
**Bottom line:** Your success isn’t going to be determined by your IQ level or your math background: it’s determined by your resilience. Even a 2019 study from Microsoft called “W[hat Makes a Great Software Engineer?](https://www.microsoft.com/en-us/research/uploads/prod/2019/03/Paul-Li-MSR-Tech-Report.pdf)” found that technical skills aren’t the most important thing when it comes to predicting success. Instead, the findings reported that great developers shared soft skills and personality traits such as perseverance, curiosity, and open-mindedness.
## So, what’s the right question to ask?
Let’s revisit our initial question: “Am I smart enough to become a developer?”
This question is loaded with myths and fallacies about learning to code. If you are serious about learning to code, it’s not the right question to be asking.
The only question you should be asking yourself is, **“Am I motivated enough to become a developer?”**
Everything else is irrelevant.
I don’t know a single developer who didn’t work hard to get where they are today. While some developers found that programming came a little naturally to them, others struggled for years. Most of us fall somewhere in the middle.
It’s important to be realistic about the trials and tribulations that come with the programming journey. You’re going to make very obvious mistakes. You might get stuck on a problem or a bug that makes you want to walk away from your code for a week. It happens to the best of us. Just remember that to get through, you don’t need uber math skills or programming savvy — what you need is **humility and persistence.**
## Motivation → Action (but don’t expect miracles)
To check if you have the aptitude for programming, get your hands dirty (or your feet wet).
Commit to your decision to learn to code, and see it through. Don’t overthink it. Remember: all you need is to put in the work.
If you’re really motivated, you need to:
- Budget time to study every week
- Be consistent
- Invest in good learning resources or programs
- Say “no” to some activities to make time for that studying
In this sense, learning to code is not so different from learning any new skill.
The not-so-good news: **there’s a lot to learn.**
The not-so-bad news: nobody figured it out the first time. Everyone struggles, at least a bit. So if you’re struggling, remember that you’re on the right track.
Don’t expect miracles. Think of it like signing up for swimming classes. The goal for day one of swim class is to get comfortable in the pool. That’s it. The actual swimming starts later (sometimes much later… and that’s okay). Similarly, you won’t be writing real applications anytime soon — at least not for the next few weeks. You would just be learning the basic constructs of how to write programs, and the fundamental building blocks of how programming languages work.
If you have gotten this far, you have already taken the first step. If you are ready to take your next step, [get your hands dirty with some basic problem-solving skills here](https://www.educative.io/module/page/k5m3gAColoJZZj89Y/10370001/4607683377364992/6679102928060416).

1,879,983 | Обнаружение потери пакетов | Если вы хотите повторно передать потерю пакетов, вы должны сначала обнаружить потерю пакетов. Если... | 0 | 2024-06-07T07:02:22 | https://dev.to/spimodule/obnaruzhieniie-potieri-pakietov-oek | mac, aps |
Если вы хотите повторно передать потерю пакетов, вы должны сначала обнаружить потерю пакетов. Если потери пакетов нет, повторной передачи не будет. В беспроводной связи обычно существует два способа обнаружения потери пакетов: механизмы мониторинга несущей и реагирования.
01 Контроль несущей
Обнаружение несущей является распространенным методом обнаружения потери пакетов, и CSMA/CA разработан на основе определения несущей. CSMA/CA также можно рассматривать как механизм повторной передачи. Этот механизм используется Wi-Fi и ZigBee, которые мы часто используем. Перед отправкой сообщения устройство связи на короткое время откроет прием. В течение этого короткого периода времени беспроводное устройство определит наличие других мешающих сигналов в том же диапазоне частот. Например, когда устройство ZigBee выполняет определение несущей, оно должно не только определять, есть ли передача по Wi-Fi или Bluetooth. сигналы, но и есть ли другие ZigBee, передающие сигналы. Если сигнал помех исходит от Wi-Fi или Bluetooth, устройство ZigBee определит, превышает ли его собственная мощность. Если мощность не превышает его собственную, оно преодолеет ее. он решительно отбросит пакет, и если устройство ZigBee встретит другие устройства ZigBee, независимо от того, имеет ли другая сторона большую мощность, чем он сам, будет активно отбрасывать пакеты, то есть позволять другим идти первыми.
02 Механизм реагирования
Другой способ определить потерю пакетов — добавить механизм ответа. Обычно протоколы связи имеют семиуровневую модель OSI. В семиуровневом протоколе, начиная с канального уровня, на каждом уровне может быть добавлен механизм ответа. Чем ниже уровень и ближе к аппаратному обеспечению, тем быстрее срабатывает механизм реагирования.
Семиуровневая модель OSI
Давайте все же возьмем в качестве примера механизм ответа ZigBee. Модель OSI ZigBee имеет механизм ответа, который в настоящее время ограничен уровнем MAC (уровень канала передачи данных) и уровнем APS (транспортный уровень). Но в реальных приложениях механизмы реагирования часто добавляются на прикладной уровень. Ответ уровня MAC является самым быстрым, также называется MAC-ACK и обычно автоматически генерируется аппаратным обеспечением беспроводного приемопередатчика ZigBee. Принимающее устройство отправляет кадр данных ZigBee в виде широковещательной рассылки через 120 микросекунд после его получения. В то же время MAC-ACK также является самым коротким кадром в ZigBee: длина кадра составляет всего 5 байт, а общая длина — 11 байт, включая преамбулу кадра и кадр синхронизации. Согласно скорости передачи данных ZigBee 250 кбит/с, каждый байт занимает 32 микросекунды, а время заполнения кадра MAC-ACK составляет 352 микросекунды. Это означает, что после отправки кадра MAC отправитель получит MAC-ACK, соответствующий кадру MAC, через 120+352=472 микросекунды. Аналогично, уровень MAC ZigBee также предусматривает, что если отправитель не получит соответствующий MAC-ACK в течение 540 микросекунд, это будет считаться потерей пакета.
MAC-ACK отправляется посредством широковещательной рассылки. Во-первых, он может уменьшить поле адреса в кадре MAC-ACK, уменьшить длину кадра и сократить время заполнения кадра ACK. Отправитель может определить, является ли он собственным, на основе кадра. порядковый номер в кадре MAC-ACK; во-вторых, MAC-ACK использует широковещательную рассылку, которая также может напоминать другим устройствам ZigBee о том, что они обмениваются данными. Если другие устройства ZigBee в это время также выполняют прослушивание несущей, они могут активно избегать этого. устройство связи. На уровне MAC ZigBee контроль несущей и MAC-ACK представляют собой двунаправленные подходы, которые могут обеспечить точность обнаружения потери пакетов. Кроме того, широковещательные сообщения ZigBee не будут генерировать MAC-ACK.
Диверсифицированный механизм обнаружения потери пакетов
Помимо механизма ответа на уровне MAC, ZigBee также имеет механизмы ответа на транспортном и прикладном уровнях. ZigBee представляет собой ячеистую сеть с несколькими переходами, и передача на уровне MAC может соответствовать только передаче с одним переходом, поэтому ZigBee также отвечает на транспортном уровне, также называемом APS-ACK. Отправитель ZigBee передает сообщение получателю ZigBee, которое пересылается несколькими узлами маршрутизатора ZigBee. После получения сообщения принимающая сторона отправит APS-ACK отправляющей стороне по тому же пути маршрутизации. Когда отправляющая сторона получает APS-ACK, она считает, что отправленное сообщение достигло принимающей стороны. Если отправитель не получит APS-ACK через 6 секунд (значение по умолчанию), данные будут считаться потерянными.
Системы ZigBee обычно открывают только интерфейсы для уровня приложений. Наиболее распространенным интерфейсом, открытым для уровня приложений, является интерфейс обнаружения, называемый «Подтверждение данных AF», который сочетает в себе потерю пакетов уровня MAC (включая потерю пакетов MAC-ACK и потерю пакетов низкого уровня). такую информацию, как потеря пакетов контроля несущей), потеря пакетов сетевого уровня и потеря пакетов транспортного уровня. Приложение верхнего уровня ZigBee может узнать, потеряно ли отправленное в данный момент сообщение.
Ответ уровня приложения
Обнаружение потери пакетов на уровне MAC и транспортном уровне относится к потере пакетов системного уровня. Другой тип потери пакетов — это потеря пакетов на прикладном уровне. Например, диммер отправляет команду «отрегулировать яркость до 50%» на устройство кондиционирования воздуха. Какой будет результат выполнения этой команды, если пакеты не потеряются? Должно быть, кондиционер выполнит «Отрегулировать яркость на 50%», но у кондиционера есть только температура, но нет яркости, а это означает, что эта команда отправляется на цель, которую не следует отправлять. В настоящее время для решения этой проблемы необходим ответ прикладного уровня. Например, после того, как кондиционер получит сообщение «Отрегулируйте яркость на 50%», он может ответить на передающую сторону ответом прикладного уровня «Смотри ясно, что я не лампочка». | spimodule |
