As of March 2024, daily active addresses for on-chain games spotted at 6M+ and daily transactions volume around $100 million. It is not just the playerbase; web3 games also lead in terms of investment. April 2024 saw the highest investment in blockchain-based games at<a href="https://bigblockchaingamelist.com/2024/04/15/big-blockchain-game-report-q1-2024/"> $988</a> million, which is almost double of January 2021’s data that stood at $288M. And it is expected to grow further to $65.7B<a href="https://www.marketsandmarkets.com/Market-Reports/blockchain-gaming-market-167926225.html"> by 2027</a>. </p>
<p>Such magic numbers in <a href="https://www.zeeve.io/web3-infrastructure-for-gaming/">web3 gaming</a> again make people curious, raising the question– what web3 games did right that's turning the spotlight towards them. These articles provide you answer to this question while explaining the Web3 Gaming Narrative in 2024 in a simplified way.</p>
<h2 class="wp-block-heading" id="h-quick-dive-into-web3-games-progress-so-far-nbsp">Quick dive into Web3 games’ progress so far </h2>
<p>The web3 gaming industry is forging ahead with creative developments and innovations, propelling it to the next phase of maturity and thus building a solid playerbase for future. Started the journey with a simple multiplayers game-Huntercoin to now powering the future-proof web3 game like Pixels- the web3 gaming ecosystem has significantly evolved. </p>
<p>Today, web3 games are built for almost every genre– be it shooter games, role play, esports, or casual games. Big entrepreneurs to individual developers, everyone is tapping into web3 to build games that can amaze players and stay relevant in the long-run. With fair gaming, player-focused economies, asset ownership, and real-money rewards– web3 games are still stealing the spotlight in 2024. </p>
<p>Additionally, all the previous pain points related to low scalability, lack of customization, higher transaction cost, etc are now tackled well with the surge of standalone L2/L3 chains built with top such as Polygon, Arbitrum, Optimism, and ZkSync's modular rollup stacks. </p>
<figure class="wp-block-image aligncenter size-large"><a href="https://www.zeeve.io/talk-to-an-expert/"><img src="https://www.zeeve.io/wp-content/uploads/2024/05/Launch-your-gaming-focused-L2L3s-at-lower-cost-1024x213.jpg" alt="" class="wp-image-68787"/></a></figure>
<h2 class="wp-block-heading" id="h-what-all-changes-web3-games-have-adopted-to-turn-the-2024-narrative-in-their-favor">What all changes web3 games have adopted to turn the 2024 narrative in their favor?</h2>
<p>Below are top moves that web3 games made to turn 2024 Web3 Gaming Narrative in their favor:</p>
<li><strong>Play-to-airdrop and node sale events:</strong></li>
<p>Web3 is bringing more native ways to engage players and shift the focus solely from playing to earn money.</p>
<p>Play-to-airdrop and verifier node sales are some of the newly introduced methods that add some additional utility to gaming tokens. </p>
<p>For example, in Play-to-airdrop tokens are distributed according to the players’ in-game activities and dedication in leveling up their characters. Play-to-airdrop is mainly focused on kickstarting a game’s economy through. Popular web3 games like Pixels, Kuroro Beats, Nifty Island, Farcana, and MixMob have already launched their Play-to-airdrop events and achieved significant success. </p>
<p>Regarding node sales, XAI’s Arbitrum-powered Layer3 and gaming-adjacent cloud-compute project- Aethir have raised <a href="https://public.bnbstatic.com/static/files/research/data-insights-exploring-crypto-fundraises-3q2023.pdf">$15M and $65M+</a> respectively from sale of their verifier node; a new type of node for additional monitoring of rollup networks. If you want to learn more about the verifier node sale and its core concept, read the article we have linked below: Zeeve Launchpad for Node Sale Infrastructure: Boost Security & Token Utility in Rollups</p>
<li><strong>Adoption of custom L2/L3 chains:</strong></li>
<p>Web3 games have faced a lot of challenges due to high traffic congestion, which leads to slow TPS, high gas cost, and impacts the network performance. As a solution, a lot of web3 games are shifting to their own standalone chain for cheaper transactions, higher TPS, and customizable features. Some of the highly-played crypto-native games like Gods Unchained and Illuvium have already built their custom chain with Immutable X– the NFT-friendly ‘validium’ powered offering with StarkWare technology offering zero gas fees, instant trades and massive scalability. Similarly, gaming L2/L3s are frequently developed with leading frameworks like Polygon CDK, Arbitrum Orbit, and OP Stack. </p>
<li><strong>The multichain approach:</strong></li>
<p>Multichain gaming is a rising concept in the web3 gaming realm that allows a gaming project to leverage a multiple ecosystem altogether, for example- Immutable, Arbitrum, Robin, and Polkadot for an additional ecosystem boost. Players of multichain games can access the games across all the supported blockchains while seamlessly switching between them. It’s just like web2 game players can enjoy their favorite game on multiple PlayStation generations. Although this multichchain strategy has some technical limitations, and increased cost & risks, it’s worth noting that 27% of total web3 games has chosen multichain approach to amaze their plates and embrace a better growth. Here’s the data:</p>
<p class="has-text-align-center">Source: Big Blockchain game report.</p>
<li><strong>A move towards more indie web3 games:</strong></li>
<p>Indie games have brought a metaphoric shift in web3 games, allowing the industry to grow tremendously and match the popularity of AAA games. That’s because today’s players are more interested in gameplay loop and mechanics rather than caring much about high density graphics or characters. At present, a lion's share of web3 games are mainly indie-level games, taking away over 94% of the total market. Casual games, RPG, and strategy games are the top genre of indie games which attracts players the most. Popular indie web3 games are Rocket League, Cult of the Lamb, Golf Story, and Moonlighter. </p>

<li><strong>Account Abstraction:</strong></li>
<p>Account abstraction (AA) is one of the new and interesting features that make we3 games more user friendly. AA brings the concept of social recovery and multi-signature wallets into games. The former offers seamless recovery of private keys in case lost because a ‘trusted group’ that you choose will still keep your keys safe. The latter enhances security of wallets by including several parties to sign transactions and approve it. A practical application of account abstraction is XRaise wallet integrated with AA functionalities to solve the problem of poor wallet UX and security challenges of web3 wallets.</p>
<li><strong>Sponsored/gasless gas transactions: </strong></li>
<p>The concept of gasless or sponsored gas transactions is introduced to get higher player retention and conversion by eliminating the challenges they face due to gas payments. Immutable, the leading gaming-based projects has already been offering sponsored gas transactions to all the gaming chains or applications building using it. Thereby, web3 games can enable their players to interact with any game’s marketplace or ecosystem through a unique digital passport without any friction. </p>
<li><strong>Web2-matching UX for web3:</strong></li>
<p>Web3 games are now offering Web2-like user experience so that players web2 players do not need to learn web3 game mechanics for just playing the game. No one cares about what's running in the backend or what technologies their game uses. All they want is a smooth UX which should resemble the games they are already familiar with. Projects like Titanium games are making this possible by allowing players to fully engage in new-gen activities such as trading assets or using the blockchain tech without any discomfort of using wallets or dealing with cryptos. Just login and start playing– that’s it! </p>
<li><strong>Use of Generative AI and Virtual reality: </strong></li>
<p>Combination of Generative AI and virtual reality (VR) creates more personalized and highly immersive experiences for players. It’s exciting for web3 gamers because they can create AI Avatars that have more creative expression, or engage with LLM and deep learning-based non-player characters, as well as create highly unique and personalized content for P2E games. All these features are mainly accommodated through metaverse games that have more than <a href="https://embryo.com/blog/metaverse-stats-2024/">600 Million</a> active users as of 2024. Use of AI and VR/AR will further grow in 2024 and beyond, which will bring even more realistic games for web3.</p>

But alongside the... | 0 | 2024-06-05T05:56:59 | https://dev.to/sennovate/identity-and-access-management-why-it-is-an-absolute-necessity-today-5hdi | identityaccessmanagemnt, identity, security, cybersecurity | The digital age has ushered in an era of unparalleled connectivity and innovation. But alongside the benefits, a multitude of security challenges have emerged. Data breaches are commonplace, cyberattacks are growing in sophistication, and regulatory landscapes are constantly evolving. In this ever-changing environment, Identity and Access Management (IAM) has become an absolute necessity for organizations of all sizes.
This blog dives deep into the world of IAM, exploring its growing importance, the factors driving its rise, and the technical aspects that make it a critical security practice. We’ll delve into facts, figures, and best practices to equip you with a comprehensive understanding of why IAM deserves a prominent place in your organization’s security strategy.
The Rise of IAM: A Perfect Storm of Security Concerns
Traditionally, user access management relied on simple mechanisms like usernames and passwords. However, the exponential growth of data, the dispersed nature of modern workforces, and the increasing complexity of IT infrastructures rendered these legacy approaches inadequate. Here’s a closer look at the key factors that have propelled IAM to the forefront of cybersecurity:
The Expanding Threat Landscape: Cyberattacks are no longer a matter of “if” but “when.” Phishing scams, malware infiltration, and social engineering tactics exploit weak access controls to gain unauthorized access to sensitive data. IAM safeguards critical information by implementing robust authentication mechanisms and granular access control policies.
Data Explosion and Regulatory Demands: Organizations collect and store vast amounts of data, including customer information, financial records, and intellectual property. Regulations like GDPR (General Data Protection Regulation) and HIPAA (Health Insurance Portability and Accountability Act) mandate strict data privacy and security controls. IAM plays a pivotal role in ensuring compliance by providing a clear audit trail of user access and activity.
Cloud Adoption and the Distributed Workforce: The shift towards cloud computing introduces new security challenges. IAM solutions extend access controls to cloud-based resources, ensuring consistent security across on-premises and cloud environments. Additionally, the rise of remote workforces necessitates secure access to company resources from anywhere. IAM facilitates this by offering secure remote access solutions without compromising security.
The Numbers Don’t Lie: The Growing Importance of IAM
The importance of IAM is reflected in its market growth. According to a recent report by Grand View Research, the global Identity and Access Management market is expected to reach a staggering $26.6 billion by 2028, signifying a significant rise in adoption. This growth is further fueled by the alarming statistics surrounding cyberattacks. Verizon’s 2023 Data Breach Investigations Report (DBIR) revealed that a whopping 81% of organizations have experienced a phishing attack in the past year. These numbers paint a clear picture: robust IAM is no longer a luxury; it’s a critical line of defense in the modern digital landscape.
The Technical Pillars of IAM: A Deep Dive
Now that we’ve established the significance of IAM, let’s delve into the technical aspects that make it such a powerful security tool. Here are some core functionalities of IAM systems:
Authentication: This process verifies a user’s claimed identity. Common methods include passwords, multi-factor authentication (MFA), biometrics, and digital certificates.
Authorization: Once a user is authenticated, IAM determines what resources and actions they are authorized to access. This is achieved by defining roles and assigning permissions based on the principle of least privilege.
Single Sign-On (SSO): SSO allows users to access multiple applications with a single login, streamlining workflows and improving user productivity.
User Provisioning and De-provisioning: IAM automates the process of adding new users to the system and granting them access to necessary resources. Conversely, it also facilitates the removal of access when a user leaves the organization.
Access Governance: This involves defining and enforcing access control policies, monitoring user activity, and conducting regular audits to ensure continued security.
Privileged Access Management (PAM): Focuses on securing privileged accounts with high access levels enforcing least privilege principle and zero trust security architecture.
Beyond the Basics: Advanced IAM Features
Modern IAM solutions go beyond these core functionalities to offer a comprehensive security posture. Here are some advanced features that add further value:
Adaptive Authentication: This approach dynamically adjusts authentication requirements based on factors like user location, device type, and access time. For instance, it may require MFA for login attempts from unknown locations.
Identity Federation: This enables users to access organizational resources using credentials from a trusted third-party identity provider, simplifying login processes and reducing password fatigue.
Self-Service Password Management (SSPR): SSPR empowers users to reset their passwords without IT intervention, improving user experience and reducing IT helpdesk burden.
Just-in-Time (JIT) Access Provisioning: JIT provisioning grants access to resources only for the duration and specific purpose required, minimizing the attack surface.

1,877,561 | How To Memoize False and Nil Values | TL;DR: if method can return false or nil, and you want to memoize it, use defined?(@_result)... | 0 | 2024-06-05T05:55:49 | https://jetthoughts.com/blog/how-memoize-false-nil-values-ruby-rails/ | ruby, rails, tutorial, development |
](https://raw.githubusercontent.com/jetthoughts/jetthoughts.github.io/master/static/assets/img/blog/how-memoize-false-nil-values-ruby-rails/file_0.jpeg)
**TL;DR: if method can return false or nil, and you want to memoize it, use defined?(@_result) instead of ||=.**
Memoization is a useful technique which helps to achieve cleaner and more efficient code. When some expensive method of an object is called, we save its value to an instance variable, so that we don’t have to do those heavy calculations again.
```ruby
class Book
def word_count
@_word_count ||= sections.sum do |section|
section.paragraphs.map(&:text).sum { |para| para.scan(/\w+/).size }
end
end
end
```
The ||= is a conditional assignment operator which translates as: *“if left side is truthy (not *false *and not *nil*), then stop right there; otherwise assign right side to the left side”*. And since in Ruby the last statement gets returned by a method, in one case it returns result of sections.sum, and in other case the previously assigned instance variable @_word_count.
This idiom is so simple that it’s easy to start using it everywhere without much thinking. But there are cases where it won’t work. We talk about *falsey* values. Consider the following methods, one of which tells if the book is referenced from any other book, and other finds the last book that referenced this one:
```ruby
class Book
def referenced_elsewhere?
@_referenced_elsewhere ||= Book.where(some_complex_and_expensive_query).exists?
end
def last_referenced_from
@_last_referenced_from ||= Book.where(some_complex_and_expensive_query).first
end
end
```
If the book was referenced by any other book, these methods will work as expected. Otherwise they will work too, but the memoization won’t ever kick in, and the complex and expensive query will be executed every time the method is called. That is because false or nil on the left side make the conditional assignment ||= always proceed to the assignment part.
So if a method can return false, the memoization should take it into account, like this for instance:
```ruby
def referenced_elsewhere?
return @_referenced_elsewhere unless @_referenced_elsewhere.nil?
@_referenced_elsewhere = Book.where(some_complex_and_expensive_query).exists?
end
```
This looks not so laconically as the previous one, but it works for boolean results.
A careful reader would have noticed though, that this way we ignore nil values when nil is a potential result. ActiveRecord’s exists? can’t possibly return nil, so we’re safe there, but .first can, and so the some_complex_and_expensive_query will hit the database on each call to last_referenced_from. There’s got to be a better way! And there is!
```ruby
def last_referenced_from
return @_last_referenced_from if defined?(@_last_referenced_from)
@_last_referenced_from = Book.where(some_complex_and_expensive_query).first
end
```
defined? is Ruby’s reserved word to check if expression is currently defined. Once we assign anything, including nil, to @_last_referenced_from, defined?(@_last_referenced_from) returns String value "instance-variable", which is truthy. It will work for all kinds of values, including also false.
To sum up, ||= is too good to forget about it, but when doing memoization, just think if the result may be boolean or nil, and if yes, use defined?.

[Construction site](https://ckbuilding.co.uk/) interior and exterior designing is a multifaceted field that marries aesthetics with functionality, ensuring that buildings are not only visually appealing but also practical and sustainable. This article delves into the intricacies of both interior and exterior design, highlighting their importance, key considerations, and the impact they have on the overall success of a construction project, especially for builders Gloucester and builder Stroud.
Interior Design: Creating Functional and Aesthetic Spaces
Interior design within construction sites involves meticulous planning and execution to optimize the use of space and enhance the user's experience. This process begins with understanding the purpose of the building and the needs of its occupants. Builders Gloucester and [builder Stroud](https://ckbuilding.co.uk/) work closely with architects and clients to create layouts that maximize efficiency and comfort in residential construction projects.
Key Elements of Interior Design:
Space Planning: Effective space planning is the cornerstone of good interior design. It involves the strategic arrangement of furniture, fixtures, and fittings to create a harmonious flow within the space. This includes considering aspects such as traffic patterns, accessibility, and ergonomics.
Material Selection: The choice of materials plays a significant role in the functionality and aesthetics of the interior. Factors such as durability, maintenance, and visual appeal are considered when selecting materials for flooring, walls, and surfaces.
Lighting: Proper lighting enhances the ambiance and functionality of a space. Designers use a combination of natural and artificial lighting to create a balanced environment. This includes task lighting for specific activities, ambient lighting for overall illumination, and accent lighting to highlight architectural features.
Color Scheme: Colors have a profound impact on mood and perception. Interior designers carefully select color palettes that align with the intended use of the space and the client's preferences. Neutral tones can create a calming environment, while bold colors can energize and stimulate.
Furniture and Fixtures: The selection of furniture and fixtures is crucial in defining the character and usability of a space. Designers consider factors such as comfort, scale, and style to ensure that the furniture complements the overall design.
Exterior Design: Harmonizing Buildings with Their Environment
Exterior design focuses on the outward appearance of the building and its interaction with the surrounding environment. This aspect of design is vital in creating a lasting first impression and ensuring that the building integrates seamlessly with its context. Builder Gloucester and builder Stroud are well-versed in the importance of exterior design for residential construction.
Key Elements of Exterior Design:
Architectural Style: The architectural style of a building reflects its purpose and the cultural context. Designers choose styles that are appropriate for the building's function and location, whether it's contemporary, traditional, or a blend of both.
Materials and Finishes: The exterior materials must be durable and weather-resistant while also contributing to the aesthetic appeal. Common materials include brick, stone, wood, and metal, each offering unique textures and finishes.
Facade Design: The facade is the most visible part of the building and serves as its visual identity. Designers use elements such as windows, doors, balconies, and cladding to create a dynamic and attractive facade. The arrangement and proportions of these elements are crucial in achieving a balanced design.
Landscaping: Landscaping enhances the building's exterior by integrating natural elements such as plants, trees, and water features. A well-designed landscape not only beautifies the surroundings but also improves environmental sustainability by providing shade, reducing heat islands, and managing stormwater.
Sustainability: Modern exterior design increasingly incorporates sustainable practices. This includes using eco-friendly materials, implementing energy-efficient systems, and designing for passive solar gain. Green roofs, solar panels, and rainwater harvesting systems are examples of sustainable features that can be integrated into the exterior design.
The Synergy of Interior and Exterior Design
The success of a construction project relies on the seamless integration of interior and exterior design. While interior design focuses on creating comfortable and functional spaces, exterior design ensures that the building is aesthetically pleasing and in harmony with its environment. The collaboration between interior and exterior designers, architects, and clients is essential in achieving a cohesive and well-balanced final product.
In conclusion, interior and exterior designing in construction sites is a complex but rewarding endeavor that requires a deep understanding of both technical and artistic principles. For builders Gloucester and builder Stroud, carefully considering the needs of the occupants and the building's interaction with its environment is paramount. This approach enables them to create residential construction spaces that are not only beautiful but also functional and sustainable. | stuward_paul_66da82c068f2 | |

](https://raw.githubusercontent.com/jetthoughts/jetthoughts.github.io/master/static/assets/img/blog/test-driven-thinking-for-solving-common-ruby-pitfalls-rails-tdd/file_0.jpeg)
*Comrade! Our Great Leader requests a web-service for his Despotic Duties! He has chosen you for completing the Booletproof Automate Bloody Repression Machine with REST API, Authorization and other munchies for glory of the Empire.*
OK, does it look like a regular specification for your customer’s new project? As professional developers we definitely can handle this. Let’s dive into our goals:
* We have to research the domain of bloody repressions
* Define pros and cons of existing systems
* Continously deliver product for Leader’s demands
* Bug should not pass (we know that repression isn’t your uncle’s joke)
So first things first, what do we know about the domain:
1. We know that the Dictator has an absolete authority.
2. Dictator assigns bureax to manage nation’s everyday needs.
3. Dictator dictates through his adjustants. They have an executive power all across the Empire.
4. Bureax deal with external APIs, such as labor unions or regional authorities.
We can work with this knowledge now. After coding for a few weeks (yes, we are using the basic TDD approach) we have a pretty common Rails application with a pretty traditional structure:
* Basic resource controllers.
* Models:
```ruby
class Dictator < ActiveRecord::Base
#...
end
class Bureau < ActiveRecord::Base
#...
end
class Adjutant < ActiveRecord::Base
belongs_to :dictator
#...
end
```
This is a pretty common situation when developers start using a framework instead of a plain old OOP. Because it’s easy enough to rails generate working solution fast. In some cases this is what you need, but often this approach leads the developer to bloated, nearly untestable system with ~1000 LOC per model.
## Pitfall One: Bloated models
But what if instead of generator approach we will write specs first.
```ruby
describe Dictator do
it "has authority to manage bureaux"
it "is Great Leader"
it "exclusively owns military forces"
#...
#...
#...
it "has many airplains"
it "can write a book"
#...
end
```
This is what we can see in many projects. Models have so many aspects of domain to deal with:
* Permissions management
* Inner state logic
* Attributes
* Relations with other models
* Aggregating and collecting data
* Processing logic for output
* Parsing income data
* etc…
Even with empty specs we can measure model size *before* it becomes a mainteiner’s nightmare. With that in mind we can start with separating of concerns early. And instead of huge Dictator model we can build something like this:
```ruby
Dictator = Struct.new(:full_name, :title, :date_of_birth) do
...
end
$dictator = Dictator.new(...).freeze
class Authority
end
class MilitaryPolicy
end
class Property
end
```
You may ask me now: What all those text above means? Where the hell are controllers, views, gems and other stuff ruby-on-rails developers are dealing with? Any of tools for faster write/run tests?
## Pitfall Two: Environment dependency
To finish this nonsense I’ll try to conclude:
1. Avoid starting project with tools, web-frameworks, test-suites, libs or other type of strict dependency (thousands of them!). Start with a clean critical look at domain.
2. You should be able to explain how system works to anyone. There is probably the lack of your knowledge in system if you cannot explain it clear enough.
3. Think about specification. With separation of concerns in mind you can start to write little pieces of a large system in isolation (unit testing).
4. Test those pieces together with some integration and interaction between them.
5. Using this approach you’ll have a large part of business logic without Rails engaged at all. Test suite runs much faster without application preloading.
6. With a huge amount of logic extracted from ActiveRecord models you can use it for the only purpose it exists: persistence management. Now validations, scopes and callbacks can be used safely (almost).
7. With system growing you may want to add layers of indirection. It is much easier to compose small low-level pieces into something like facades then to decompose heavy tightly-coupled monolithic models.
So I use the rule of thumb for myself: try to test before code *and* try to think before test. Anyway, thank you for reading, hope it was not *that* boring. :)

When I see... | 0 | 2024-06-05T05:52:47 | https://jetthoughts.com/blog/mock-everything-good-way-sink-tdd-testing/ | tdd, testing, development | ***Have you found a lot of code with mocks and stubs? But how do you feel about it? When I see mocks/stubs, I am always looking for the way to remove them.***
## Application lifecycle with mocking everything strategy:
1. Everything starts from a happy developer and a clean architecture with fastest tests.
2. And one day in the middle of development we have changed the core application business logic.
3. We have changed our code base according to new requirements, and now we expect to have failed tests …. oops, most of expected tests pass successfully instead of failing.
4. We found mocks in the code, updated them.
5. And now we have a hunch, that tests are cheating on us, so we should find all similar mocks and update them to correspond the last requirements.
6. And even after reviewing all tests, we still have considerable misgivings.
## What has just happened:
With mocks, we cannot rely on implemented architecture because using mocks/stubs we built a fake application from small chunks. And placed them in different parts of test suites. As it turns out, changes to application architecture will not make our tests fail. So we should look for all our chunks and update them ourselves. And that’s duplication, baby!
## Mocking/Stubbing Principles:
Mocks and Stubs are powerful tools and should be put to a good use. Here are my principles when to use them:
* Stub/mock only the stuff that is impossible to setup/simulate like remote services responses, time and etc.
* Stubs/Mocks only specifications, which will not be changed at all: external applications, libraries.
In other cases when I have a desire to mock something, then this is the first sign of a poor design. And I understand if I cannot add tests for simple application behavior on initial stages, then how I will support it when it will become a whale of an application? Mocked behavior is a sort of our technical debts which we should fix as soon as possible.
## Summary:
Do not overuse mocks and stubs ;) Most popular alternatives to mocks and stubs are fakes, which have some advantages of mocks, but are much easier to support.

For those of you who don’t know who Joel Spolsky is here are some facts:
* Worked at Microsoft
* Founded [Fog Creek Software](https://www.fogcreek.com), [Stack Exchange, Inc](http://stackexchange.com/about).
* Guilty for the world to see some interesting web products:
* Wrote [an awesome post](http://www.joelonsoftware.com/articles/fog0000000043.html) about test to rate the quality of software team.
## 12 steps of Joel’s test in reality of JetThoughts projects:
### Do you use source control?
Hell yeah! Is there anyone who still develops software without using source control in 2016?! We use git as it is comfortable, reliable and modern.
### Can you make a build in one step?
Yes, we can! Rolling out new code updates, features and hotfixes is what we do constantly. At context of our web projects written with Ruby on Rails, it’s a question of a single command to start deploy. For this purpose we use capistrano [https://github.com/capistrano/capistrano](https://github.com/capistrano/capistrano)
### Do you make daily builds?
To cover this part we run tests on CI on every commit pushed. This allows us to track project state and react right away if anything went wrong. What I really think we need to borrow from Joel experience is having the last guy who messed up build being responsible(“babysitting”) builds until someone else breaks it.
### Do you have a bug database?
We keep an eye on bugs using github issues. It totally meets our needs in having track on bugs. Steps to reproduce, expected and buggy behaviour is described in the issue description. Developer can be assigned to certain bug. Fixing bug can be planned using milestones or adding a label.
### Do you fix bugs before writing new code?
Sure, bugs should be fixed before writing new code. At the same time, bugs can be totally different. So when S&S comes to you with ‘we have bug, a button is aligned to the left!’ you should track and schedule this, but this bug does not prevent you from writing new code as it’s not crucial. Do you have an up-to-date schedule?
It’s always hard to get any estimation from a developer. It’s getting even harder when you ask to give the precise estimation. But a client wants to know when issues will be done. We provide estimations for the client if task requirements are clear and precise. Otherwise, we provide the time needed to give an estimation, this time might be spent on reproduction of a bug, investigation of an issue or it’s cause, making a spike to try some solution. Estimating and scheduling are important for R&D team as well — these make you decide issues importance and priorities. This way most needed and valuable changes will be done first.
### Do you have a spec?
It depends. Since JT is mainly an outstaffing company, it relies on client/project communication flow. But I think we have specs in every project we develop, the only thing that varies is a definition of spec. It could be wireframes, user stories, even an idea that client passes to R&D leaving more freedom for developers.
### Do programmers have quiet working conditions?
Not always. Developers get distracted to answer someone’s questions, review PRs, have lunch, etc. To reduce the factor of distraction we are coming up with daily (if needed) meeting to sort out most of the questions right away. This allows developers to focus on their tasks for the rest of the day.
### Do you use the best tools money can buy?
No. Our minimal stack consists of tools that are free(at least for some capacity used). Using best(and most expensive) tools depends on clients needs and will. I guess this agile approach is comfortable for clients.
### Do you have testers?
✔. QA is needed for the quality product. Period.
### Do new candidates write code during their interview?
Yup. It’s taking most of the interview time. A candidate is asked to solve some coding tasks. Tasks have different difficulty to meet different developer skill levels. Tasks cover both programming/algorithmic and language/technology purposes. Flavoured with common interview questions it gives you a complete image of a candidate.
### Do you do hallway usability testing?
Not really. We complete this by having meetings and QA’s.
I guess Joel test is useful to rate the quality of a software team. Cases may vary and you will need to come up with ideas on how to complete some of the steps, I hope vision of steps completion in JetThoughts will help you with that.

1,877,554 | Why Testing is Crucial in Web Mobile App Development | In the fast-paced world of web mobile app development, testing is often viewed as an optional step.... | 0 | 2024-06-05T05:50:27 | https://dev.to/danielpeter/why-testing-is-crucial-in-web-mobile-app-development-5b1 | mobileappdevelopment, alphabravodevelopment, apptesting, softwaretesting |
In the fast-paced world of [web mobile app development](https://www.alphabravodevelopment.com), testing is often viewed as an optional step. However, skipping or rushing through testing can lead to disastrous consequences. Testing is a critical phase that ensures the functionality, security, and usability of an app. Here’s why testing is crucial in web mobile app development.
## Ensuring Functionality
The primary goal of testing is to ensure that the app works as intended. Functional testing involves checking every aspect of the app’s operations, from basic functions like user logins and data entry to complex processes like transaction processing and data synchronization. It helps identify and fix bugs that could cause the app to crash or behave unexpectedly.
Without thorough testing, users might encounter issues that prevent them from using the app effectively. For example, a shopping app that fails to process payments correctly can lead to frustrated customers and lost revenue. Ensuring functionality through rigorous testing is essential for delivering a reliable app.
## Enhancing Security
Security is a significant concern for web mobile apps, especially those handling sensitive user information like personal data, payment details, and login credentials. Testing helps identify vulnerabilities that could be exploited by hackers. Security testing includes checking for weak points such as:
- **Data Encryption**: Ensuring that data transmitted between the app and the server is encrypted and cannot be intercepted.
- **Authentication**: Verifying that only authorized users can access certain features or data.
- **Input Validation**: Ensuring that all input fields are protected against common attacks like SQL injection or cross-site scripting (XSS).
By addressing these vulnerabilities through testing, developers can protect user data and maintain trust.
## Improving Performance
Performance testing evaluates how well an app performs under different conditions. This includes checking how the app responds to high traffic volumes, how quickly it loads, and how efficiently it uses device resources like memory and battery. Performance testing ensures that the app remains responsive and fast, even under heavy use.
An app that performs poorly can lead to user frustration and negative reviews. For instance, if a social media app takes too long to load images or videos, users might abandon it for a competitor. Testing helps optimize performance, ensuring a smooth and satisfying user experience.
## Enhancing Usability
Usability testing focuses on the user experience. It involves evaluating how easy and intuitive the app is for users to navigate. This type of testing often involves real users interacting with the app and providing feedback. Usability testing helps identify issues such as:
- **Complex Navigation**: Users should be able to find what they need quickly and easily.
- **Inconsistent Design**: The app’s design should be consistent across different pages and features.
- **Accessibility**: The app should be usable by people with disabilities, complying with accessibility standards.
By incorporating user feedback into the development process, developers can create apps that are user-friendly and enjoyable to use.
## Ensuring Compatibility
Web mobile apps need to work across a wide range of devices and operating systems. Compatibility testing ensures that the app functions correctly on different platforms, screen sizes, and resolutions. This type of testing helps identify and fix issues that might occur on specific devices or browsers.
For example, an app that works perfectly on Android might have layout issues on iOS. Compatibility testing ensures a consistent experience for all users, regardless of the device they are using.
## Reducing Costs
While testing might seem like an added expense, it can actually save money in the long run. Identifying and fixing issues during the development phase is much cheaper than addressing them after the app has been launched. Post-launch fixes can involve significant time and resources, including potential downtime and lost revenue.
By catching and resolving issues early, testing helps avoid costly fixes and minimizes the risk of negative impacts on the business.
## Building Reputation
A well-tested app contributes to a positive reputation for both the app and its developers. Users are more likely to trust and recommend an app that works reliably and provides a great experience. On the other hand, an app riddled with bugs and performance issues can quickly gain a bad reputation, leading to poor reviews and declining user numbers.
Thorough testing demonstrates a commitment to quality, helping to build a strong reputation in the competitive app market.
## Conclusion
In summary, testing is a critical component of web mobile app development. It ensures that the app functions correctly, protects user data, performs well, is user-friendly, works across different devices, and ultimately saves costs. Moreover, a well-tested app helps build a positive reputation, attracting and retaining users. Skipping testing might seem like a shortcut, but it’s a risk that can lead to significant problems down the line. Investing in thorough testing is essential for delivering a successful, high-quality web mobile app. [Alpha Bravo Development](https://tracxn.com/d/companies/alpha-bravo-development/__l9K_J0aiqpIYJNEHNNwbXeoXcBEjD1fbPMtsti2lmFw/founders-and-board-of-directors) is dedicated to providing top-notch testing to ensure the success of every app we develop.

1,877,550 | Responsive or Adaptive Design? Find out which one is better for you | JetThoughts has launched a new project recently. Whole front-end team was set and started... | 0 | 2024-06-05T05:49:06 | https://jetthoughts.com/blog/responsive-or-adaptive-design-find-out-which-one-better-for-you-webdesign/ | design, webdesign, layouts | 
JetThoughts has launched a new project recently. Whole front-end team was set and started developing the UI part. They designed selected and adapted the suitable libraries, plugins, distributed the tasks — everything as usual. At this stage, a question arises: how the customer sees his future application. Fortunately, we’ve already had several ready design layouts based on which we could estimate the basic layout. Was it responsive in this case…. or adaptive after all?
There are many posts and discussions on a subject in what way a responsive design differs from an adaptive one. Why use one or another, what types of layers the global information resources, social networks (Facebook, Twitter, AIRBNB) use — we are going to consider this issue for our part. First, let’s have a look at peculiarities of these approaches once again.
## Responsive Design
When we talk about the responsive design we mean the layer only. Ethan Marcotte, the author of this concept, at his time (in [2010](http://alistapart.com/article/responsive-web-design), has singled out 3 basic definitions of responsive layout:
* media queries,
* fluid grids,
* flexible images.
You should pay attention to the concept of fluid and flexible. Initially, we prepare our content for a proper display on most devices and screens. This integrated approach, in some sense, proves its worth — we send all the content to the client browser, and the browser handles it with regard to the window size.
We use a single template for all devices; our flexible images are loaded in full size, and then the size is adjusted to fit the block size. All these affect the download speed. And we have to wait longer for loading than if the browser would get the content exclusively for the device and the window size. Here the adaptive design comes forward.
## Adaptive design
“Adaptive” is a broader concept, and, in my opinion, the responsive design is only a part of the adaptive in this instance. It is believed that the difference of the adaptive design consists only of the fixed width of the block on various screens. But it’s not actually true. In this case, the concept of adaptive design and adaptive layout are identified. Apart from the fact that it “adapts” to different sizes of the screen, the content may also use different layouts for different devices of screen size; styles, images, JavaScript, event handlers for a particular device, and screen size will be loaded separately. This optimization can increase the page loading speed more than twice.
Certainly, faster loading with optimized code for a particular device is a good option for a design. However, it requires an excellent knowledge of JavaScript and CSS, more meticulous work to set up the service display and, more time in general. It’s up to you to decide whether it’s worth it. You should also remember that we can identify the device on server-side by transmitting a ready code to the client without additional requests.
The above-mentioned social networks use a hybrid approach in the most cases. Twitter uses an adaptive layout for laptops and a mobile version for tablets and smartphones. Facebook has nearly the same approach. Google, for instance, advocates a responsive design as the [king of layouts](http://www.socialmediatoday.com/technology-data/2015-02-18/why-google-recommends-responsive-web-design).
So, whether to use the adaptive design? If you are looking for a comprehensive solution, the adaptive approach is unlikely to be the best choice. In fact, you should take into account the actual needs of the project and its users. The use of adaptive design pays its way if you need to display your application on several specific devices, or you want to implement various experiences of interaction for users on different devices, or if the service speed on mobile devices is critical for you.
Responsive design remains popular, because it is easy to set up a relatively good performance. In fact, the adaptive design might ensure even faster productivity, but a “convenient” solution for working with the adaptive design has not been found yet.

*TL;DR Fast, simple & cheap project setup for a start-up, that can handle up to a thousand users.*
### 0. Intro to the problem
Choosing Ruby on Rails (RoR) as a platform for your startup is a good choice for many reasons. One of them is the simplicity of a framework, and that’s why a lot of start-up founders use RoR.
While developing an application, you may and will face some common problems. There are plenty of services, that can deal with them, saving your time and money. I’ve made a list of services & add-ons I suggest to use for building a working application prototype that can host up to 1k users.
Let’s get started.
### 1. Hosting platform
Using Platform as a Service (PaaS) makes sense because it encapsulates many tedious system administration functions and allows you to focus on your app by removing the need to maintain a server infrastructure.
There are a lot of PaaS solutions for different needs and for different prices. You can check by yourself: [http://paasify.it](http://paasify.it). In JT we have chosen to use Heroku — one of the best-known PaaS providers, especially in the Ruby community.
[Heroku](https://www.heroku.com) runs on top of [Amazon Web Services (AWS)](https://aws.amazon.com). Key benefits for me are:
* single command deployments;
* fully-managed database service;
* automatic load balancing;
* on-demand scaling.
With Heroku, you can get things running in 5 minutes in a simple fashion and as you scale or need more horsepower the process of resizing an instance or adding more instances is much simpler than a traditional cloud or dedicated server model. Another benefit is add-ons, that provide solutions for nearly every need our application might have. These include databases, caching, logging, email/SMS, errors and exceptions, metrics, analytics, and more. Many add-ons have free or low priced options and scale with your app.
As the most similar alternative, you can use [Ninefold](https://ninefold.com) or [OpenShift](https://www.openshift.com). They both provide free plans and can run almost any database while Heroku uses [PostgreSQL](http://www.postgresql.org).
### 2. Database
[Heroku Postgres](https://www.heroku.com/postgres) is recommended on Heroku because of its tight integration with the platform and excellent management services and tools. It is a powerful database-as-a-service based on mature, feature-rich PostgreSQL database server. From Heroku blog post: “At Heroku, we believe PostgreSQL offers the best mix of powerful features, data integrity, speed, standards compliance, and open-source code of any SQL database on the planet”.
Heroku Postgres offers a wide spectrum of plans appropriate for everything from small personal app to large-dataset applications. Plans are divided into 4 large tiers. The key factor in each tier is the uptime expectation and row limit. Free ‘hobby-dev’ plan offers a 10k row limit and 4 hours downtime per month.
Since I recommended using Heroku, Postgres seems to be an obvious choice. However, there are options for applications currently running on MySQL. You can use ClearDB add-on, or run MySQL locally, but convert to PostgreSQL when migrating to Heroku using the mysql2psql gem, but it can be really painful. PG Backup helps to manage backups from the Heroku Postgres database. It can periodically take backups automatically.
### 3. Error-tracking
When an error occurs in our app, we want to know about this as soon as possible. Instead of putting an error in logs and scanning it later, we can use an error-handling tool, which catches an error, saves it’s backtrace context, and sends an email with it to you.
[Rollbar](https://rollbar.com) is a great error-tracking service. It alerts us on exceptions and errors, provides analysis tools and dashboard, so we can see, reproduce, and fix bugs quickly when something went wrong. This service has a possibility to log not only uncaught exceptions but any messages. By default, the messages are reported synchronously, but you can enable asynchronous reporting using [Sidekiq](http://sidekiq.org), [girl_friday](https://github.com/mperham/girl_friday), or [Resque](https://github.com/resque/resque). Also, you can provide your own handler and a failover handler to be confident, that your error is tracked and delivered in the case of primary handler’s fail.
The Rollbar’s ancestor, [Airbrake](https://airbrake.io), is another good choice (if you can afford it, because it has no free plan). You can see a detailed comparison between these two here: [https://rollbar.com/vs/airbrake/](https://rollbar.com/vs/airbrake/). The same applies to [Honeybadger](https://www.honeybadger.io) — one more popular modern error management service for rails. In a nutshell, they do similar things but may have different bells and whistles.
### 4. Log aggregator
Logging is useful to explain the non-exceptional behavior of the application. It provides an audit trail, that can be used to understand the activities of complex systems, to diagnose problems, and to gather performance-relevant data. [Logentries](https://logentries.com) is a powerful log management tool. It offers a nice graphic representation of log data through web UI. It integrates with [New Relic](http://newrelic.com), providing combined search across both services. When Logentries throws an error, we can look at New Relic and see how badly it’s affecting our application.
[Logentries](https://logentries.com) free plan is allowing 1-week storage with 33MB of log volume per day. As an alternative, I recommend taking a look at popular [Papertrail](https://papertrailapp.com), [Loggly](https://www.loggly.com), [FlyData](https://www.flydata.com/), or [Splunk](http://www.splunk.com).
### 5. Performance monitoring
It’s pretty obvious, why we should monitor the application’s performance. Application Performance Monitoring (APM) tools are helping us with that. I prefer using [New Relic](https://newrelic.com) and it has no significant alternatives for me. However, you can look at [AppSignal](https://appsignal.com), [Scout](https://scoutapp.com/plugin_urls/181-ruby-on-rails-monitoring), [Datadog](https://www.datadoghq.com). New Relic is a solid monitoring solution, that helps to measure front-end and back-end performance, bottlenecks in database, and customer satisfaction. It can be set up to ping the application every 30 seconds to keep it alive.
### 6. Email testing
It is unacceptable to bring a risk of accidentally sending dummy emails to real customers. To test email notifications, I recommend using [Mailtrap](https://mailtrap.io). Mailtrap is a dummy SMTP server for testing emails sent from development and staging environments. [Mailcatcher](https://mailcatcher.me) can be a replacement here. If you are looking for service, that helps to ensure your emails reach customer inboxes, you should look at [Mailgun](https://www.mailgun.com), [Sendgrid](https://www.sendgrid.com), or [Mandrill](https://www.mandrill.com). All of them provide email deliverability expertise, and they have solid free plans, offering 10k emails per month.
### 7. Caching
One of the most effective ways to improve the application’s performance is caching regularly accessed data. There are two leading key-value stores: [Memcached](https://memcached.org) and [Redis](http://redis.io). I prefer using [Memcached Cloud](https://redislabs.com/memcached-cloud) add-on for caching because it was originally intended for it and is easier to set up, and using Redis only for background jobs.
### 8. Background jobs
It’s hard to find a Rails app, that is not using background job processing. Background jobs help with handling computationally difficult tasks and long-running requests. Heroku has the ability to include not just a free web, but also one free worker, which can be used for background jobs, so there is no need for additional add-ons for it.
### 9. CDN
Content Delivery Networks (CDN) are simple to use services that serve your website assets much faster than how your website hosting service can deliver them. CDNs are based on a large number of worldwide servers, or “edges”. When visitors visit your website, they are automatically routed to the nearest edge location, so content is delivered with the best possible performance with a much-reduced latency. CDN allows offloading all requests for the static assets off of your web dynos, which in turn will free those dynos to handle more requests for dynamic content.
There are many CDN providers available today. Among the most popular are [AWS CloudFront](https://aws.amazon.com/cloudfront) and [CloudFlare](https://www.cloudflare.com). Both are pretty cheap and provide relatively similar performance. To see setup guide, visit [http://www.higherorderheroku.com/articles/cloudflare-dns-heroku/](http://www.higherorderheroku.com/articles/cloudflare-dns-heroku/) or [https://devcenter.heroku.com/articles/using-amazon-cloudfront-cdn](https://devcenter.heroku.com/articles/using-amazon-cloudfront-cdn).
### 10. Image Uploading and Transforming
When dealing with image processing, we can use [S3](https://aws.amazon.com/s3) and our own transformers, but in order to simplify development, better to use some free SaaS solution. We can rely on it when dealing with a common set of problems. Every image uploaded can be dynamically transformed to any thumbnail size, file format, and quality so we are able to test different settings that best fit user expectations. All images can be automatically stripped and optimized in size and delivered from a CDN using correct cache settings.
I recommend using [Cloudinary](https://cloudinary.com) as an image management solution. Once uploaded to Cloudinary, images are stored on Cloudinary’s Amazon S3 account. If you wish, you can automatically back your images to your own S3 as well. As an alternative service, you can use [Blitline](https://www.blitline.com) for image processing.

## What I Built
<!-- Tell us what you built and what you were looking to achieve. -->
Here's my first JS / CSS challenge. In an era where everything is built using a framework or design system, it's been a long time since I've had any fun with css. After years of using JS frameworks, it's time to bring out the old js vanilla memories.
## Demo
<!-- Show us your project! You can directly embed an editor into this post (see the FAQ section from the challenge page) or you can share an image of your project and share a public link to the code. -->
{% codepen https://codepen.io/Byuku/pen/yLWMJeo %}
## Journey
<!-- Tell us about your process, what you learned, anything you are particularly proud of, what you hope to do next, etc. -->
For this project, I used keyframes, transform, transition for the different animations.
I wanted to create double-sides cards :
- sideA will show the beach name with a button that will triggered the rotation.
- sideB will display the beach description.
Each time you click on the button trigger, the current item will rotate as the previous should go back to the default state
For this, I rework the DOM thanks to JS vanilla and add some classes to manage the css
This project is also responsive, we have a little zoom effect for the desktop query
I relearn to use some scss variables : mixin, maps, include
It was nice to participate in the challenge, now I'm going back to React and my company design system ✌🏽
<!-- Team Submissions: Please pick one member to publish the submission and credit teammates by listing their DEV usernames directly in the body of the post. -->
<!-- We encourage you to consider adding a license for your code. -->
<!-- Don't forget to add a cover image to your post (if you want). -->
<!-- Thanks for participating! --> | byuku |

](https://raw.githubusercontent.com/jetthoughts/jetthoughts.github.io/master/static/assets/img/blog/how-we-temporarily-transformed-our-usual-workflow-for-tight-deadline-agile/file_0.jpeg)
## Time makes rules
Every time when we start working on a new project, short iteration or just a new feature, we almost always worry about a delivery deadline. «Do we have enough time for this feature?», «Will we do it in time before customer loses the trust to us…». We always try to give an accurate estimation.
We always wonder: «Will we be able to make it within this ETA and own workflow?». But, sometimes, when we had begun working on a particular task and had investigated it deeper, you realise that you don’t fit into the initial estimation.
## Our workflow
Our workflow is a mixture of Kanban and Scrum methodologies.
For example, we use default scrum board, but WIP is controlled by our workflow states; we have something like «daily scrum», but per week; we have clearly defined scrum roles, but our team is not cross-functional and its members specialize in certain tasks. Also, we plan the set of tasks for the following week (Sprints) in a close cooperation with our customers and usually wait for the next sprint with new changes.
But sometimes we can add high-priority tasks to the current sprint. When the code is ready, it is subject to testing and code reviewing (twice!). Each stage repeats until result matches task requirements and style guides which we follow. In our work processes we stand for a couple of simple rules:
* High priority tasks first.
* Cover new changes with tests.
* Add tests before fixing new bugs.
* Do not merge until tests are green.
* Do not merge your own branches.
* And once we have broken all the rules…
## Rush development
One morning after a regular meeting with our customer we figured out that we have to implement huge changes in three days. Considering that before this day estimations were longer (about tenfold more), we had no idea how we can do it in the shortest time possible. Needless to say that day we had one more meeting asap. We have strong loyalty relation with this customer and have been building long-term success with him, so we have not refused a task and after some time of thoughts and calculation of story points, we started heavy work.
Just imagine the following: ten developers; about seventy percent of uncompleted work; all team works hard in a single branch on a huge web application and solves conflicts, which naturally appear in similar situations.
Ruby developers make new layouts according to the complicated mockups, front-end team changes Rails helpers and team lead pushes fully implemented pages one by one. Such mode did not give us even the slightest chance for an accurate division of roles. Each member was a manager, a developer and a tester. Everybody had to be sure in their work quality, whenever he’s done something, and in the work of a person who pushed commit before him. If rebase brings some bugs from the previous commit — these bugs become yours. But, anyway, help came quickly as soon as you needed it because all developers stuck to one simple rule: “One task down for someone — one task down for the whole team…”
This proceeded from morning (~ 10 AM) to deep night (~ 3–4 AM) for the whole three days. And after such wild development process we were done with all tasks and have presented a redesigned application, which was naturally crude, but nevertheless was acceptable to our customer.
## Why should you avoid it?
The main reason is the price you have to pay.
### Team members health
It means exhaustion of an organism physically and psychologically. And the head and eyes which ached a bit for a week after our experience from time to time were not the worst. The worst is a feeling of a certain lostness which did not leave some members of our team throughout a long time. And I need to mention the efforts you have to make to return to the work/rest mode habitual for you…
### Project health
But all the above-mentioned reasons concern only a human factor (team members’ health, to be exact). But what about the project and its “health”? Those three days of fast development set aside a bunch of technical debts in a form of the absence of tests and difficult-to-support back-end logic, which has polluted our views, many duplications in CSS files and JavaScript functions which might not have worked in all cases. Therefore, besides the worsened health, you will be expected by a heap of technical debts, which will take months to be paid.
## To sum up
This tense deadline and a rush development style were very stressful for our team. But thanks to it we have not only become a more amicable team, but also learned to adapt to extreme situations. The only positive moment, except for the experience which we received, is the unity. I do not want to tell that you cannot be the real team in your usual workflow. But anyway, having a common enemy (many tasks, which must be done in a short time) brings together and makes team unity stronger.
Nevertheless, I may recommend this workflow only for very extreme cases. So if you have a time issue or you want to try the new you can try something similar, at your own risk of course.

1,877,543 | 5 Steps to Add Remote Modals to Your Rails App | Sometimes you don’t want to write big JavaScript application just to have working remote modals in... | 0 | 2024-06-05T05:41:44 | https://jetthoughts.com/blog/5-steps-add-remote-modals-your-rails-app-javascript-ruby/ | javascript, ruby, rails, tutorial | Sometimes you don’t want to write big JavaScript application just to have working remote modals in your rails application. The whole JSON-response parsing thing looks big and scary. Why can’t we simply render our views on a server and just display them as modals to users? Let’s take a look at how we can implement this with elegance.
***Note: I am using [bootstrap 4](https://getbootstrap.com/) modals here but this solution can be adapted to any JS modals implementations.***
Check out [working demo](https://remote-modals-rails.herokuapp.com/) and [source code](https://github.com/jetthoughts/remote_modals_demo).
## Step 0. Prepare your bundle
### Rails 4.2+
respond_with and the class-level respond_to methods [have been extracted](http://guides.rubyonrails.org/upgrading_ruby_on_rails.html#responders) to the responders gem. To use them, simply add gem 'responders', '~> 2.0' to your Gemfile.
### Other dependencies
You need to installbootstrap and jquery. Don’t forget to include them to asset pipeline.
```
gem 'bootstrap'
gem 'jquery-rails'
```
## Step 1. Modify your layout files
```html
<%# app/views/layouts/modal.html.erb %>
<div class="modal" id="mainModal" tabindex="-1" role="dialog" aria-labelledby="mainModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<h4 class="modal-title" id="mainModalLabel">
<%= yield :title if content_for? :title %>
</h4>
</div>
<%= yield %>
</div>
</div>
</div>
```
Also, we need to define a place where modals will be rendered. Let’s add it to application layout:
```html
<%# app/views/layouts/application.html.erb %>
<div id="modal-holder"></div>
```
## Step 2. Create modal.js
Now, we can move to the JavaScript part of our modals implementation. We want our links with data-modal attribute to be rendered in modal windows.
Also, we need to work on the remote forms submit. The application should properly handle redirects to the given page and form re-displays with errors. Let’s assume that if the response has Location header set, then we need to redirect the user to the given location, otherwise, we will re-display the form.
```javascript
// app/assets/javascripts/modals.js
$(function() {
const modal_holder_selector = '#modal-holder';
const modal_selector = '.modal';
$(document).on('click', 'a[data-modal]', function() {
const location = $(this).attr('href');
// Load modal dialog from server
$.get(
location,
data => { $(modal_holder_selector).html(data).find(modal_selector).modal() }
);
return false;
});
$(document).on('ajax:success', 'form[data-modal]', function(event){
const [data, _status, xhr] = event.detail;
const url = xhr.getResponseHeader('Location');
if (url) {
// Redirect to url
window.location = url;
} else {
// Remove old modal backdrop
$('.modal-backdrop').remove();
// Update modal content
const modal = $(data).find('body').html();
$(modal_holder_selector).html(modal).find(modal_selector).modal();
}
return false;
});
});
```
## **Step 3. Create Modal Responder**
OK, now when we have prepared our front-end, we need to implement the server-side logic.
I am widely using respond_with in my applications, so I want something similar for modals.
The respond_with method is using the ActionController::Responder class for result rendering. Let’s make our own implementation and call it ModalResponder.
```ruby
class ModalResponder < ActionController::Responder
cattr_accessor :modal_layout
self.modal_layout = 'modal'
def render(*args)
options = args.extract_options!
if request.xhr?
options.merge! layout: modal_layout
end
controller.render *args, options
end
def default_render(*args)
render(*args)
end
def redirect_to(options)
if request.xhr?
head :ok, location: controller.url_for(options)
else
controller.redirect_to(options)
end
end
end
```
Here, we are overriding render and redirect_to methods to give them the new behavior when request is made via XHR.
If request is made via AJAX we want render to use our custom modal layout. And instead of redirecting we want redirect_to to return only headers with location header set which will handle our JS logic.
## **Step 4. Modify Application Controller**
Now, when we have our custom, let’s add our own helper respond_modal_with. It will call the respond_with method with ModalResponder specified as the responder:
```ruby
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
def respond_modal_with(*args, &blk)
options = args.extract_options!
options[:responder] = ModalResponder
respond_with *args, options, &blk
end
end
```
## **Step 5. Use it!**
OK, now we have everything to use our cool remote modals. Let’s use them!
Well, in the first place, we need to add a link to the modal:
```html
<%# app/views/layouts/_header.html.erb %>
<%= link_to 'Add Message', new_message_path, class: 'btn btn-outline-success my-2 my-sm-0', data: { modal: true } %>
```
Now, we need to modify our controller using our new respond_modal_with method instead of respond_with:
```ruby
# app/controllers/messages_controller.rb
class MessagesController < ApplicationController
respond_to :html, :json
def new
@message = Message.new
respond_modal_with @message
end
def create
@message = Message.create(message_params)
respond_modal_with @message, location: messages_path
end
private
def set_message
@message = Message.find(params[:id])
end
def message_params
params.require(:message).permit(:name, :body)
end
end
```
And, finally, you should add two attributes to your form:
```html
<%# app/views/messages/_form.html.erb %>
<%= simple_form_for(@message, remote: request.xhr?, html: { data: { modal: true } }) %>
```
`remote` is used to tell jquery_ujs to submit this form with ajax. I am using request.xhr? because I want this form be fully functional both when displayed in modal and separately.
data-modal is used to tell our script to handle this form as the modal form.
I’ve created a small [demo application](https://remote-modals-rails.herokuapp.com/) which you can find here: [source code on github](https://github.com/jetthoughts/remote_modals_demo).

Positive reinforcement is a popular... | 0 | 2024-06-05T05:41:31 | https://dev.to/larsonsteve48/positive-reinforcement-dog-training-techniques-3n16 | dog | Training your dog can be a challenging yet rewarding experience. Positive reinforcement is a popular and effective method that emphasizes rewarding good behavior rather than punishing bad behavior. This approach not only strengthens the bond between you and your pet but also promotes a happy and well-behaved dog. In this article, we will explore various positive reinforcement techniques to help you train your dog effectively. For more tips and resources, visit [Sharp Savvy](https://sharpsavvy.com/).
## What is Positive Reinforcement?
Positive reinforcement involves adding something pleasant or rewarding immediately after a behavior to increase the likelihood of that behavior occurring again. This method contrasts with negative reinforcement, which involves removing an unpleasant stimulus, and punishment, which aims to decrease a behavior. Positive reinforcement focuses on what the dog does right and encourages repeating those actions.
## Benefits of Positive Reinforcement
- **Builds Trust and Strengthens Bond:** Positive reinforcement helps build a strong, trusting relationship between you and your dog.
- **Encourages Learning:** Dogs are more willing to learn when training is fun and rewarding.
- **Reduces Fear and Anxiety:** Unlike punishment-based methods, positive reinforcement reduces fear and anxiety in dogs.
- **Promotes Good Behavior:** Consistently rewarding good behavior encourages your dog to repeat those actions.
## Effective Positive Reinforcement Techniques
### Treats
Treats are one of the most common and effective rewards. Use small, tasty treats that your dog loves. It's important to give the treat immediately after the desired behavior so your dog makes the connection.
### Praise
Verbal praise, such as saying "good dog" in a cheerful tone, can be a powerful reward. Dogs respond well to the sound of your voice and your positive energy.
### Toys
For dogs that love to play, toys can be a great reward. Use your dog's favorite toy as a reward for good behavior during training sessions.
### Clicker Training
Clicker training involves using a small device that makes a clicking sound to mark the exact moment your dog performs the desired behavior. The click is followed by a treat, helping your dog understand what action is being rewarded.
### Consistency is Key
Consistency is crucial in positive reinforcement training. Ensure everyone in your household uses the same commands and rewards the same behaviors. This helps prevent confusion and reinforces learning.
## Common Mistakes to Avoid
### Inconsistent Timing
Reward your dog immediately after the desired behavior. Delayed rewards can confuse your dog and make training less effective.
### Overfeeding
While treats are an excellent motivator, overfeeding can lead to obesity. Use small treats and balance them with your dog's regular diet.
### Lack of Patience
Training takes time and patience. Avoid getting frustrated if your dog doesn't learn immediately. Consistent practice and positive reinforcement will yield results.
## Conclusion
Positive reinforcement dog training techniques are a humane and effective way to train your dog. By focusing on rewarding good behavior, you can foster a trusting and happy relationship with your pet. Whether you use treats, praise, toys, or clicker training, the key is to be consistent and patient. Start implementing these techniques today and enjoy the benefits of a well-trained, contented dog.

1,877,508 | Why you should use Winston for Logging in JS | Logging with Winston in JS Winston JS is a popular open-sourced Javascript logging library... | 0 | 2024-06-05T05:17:26 | https://dev.to/alimalim77/why-you-should-use-winston-for-logging-in-js-d76 | webdev, javascript, programming, tutorial | # Logging with Winston in JS
Winston JS is a popular open-sourced Javascript logging library used to write logs in code with support extending upto multiple transport. A transport helps the log to be present at multiple levels, be it storage at database level but logs on the console.
The transports can be either console, database, files or remote servers making it highly flexible to get logs as per the requirements. The core transports that are part of Winston are Console, File and HTTP while there is option to write logs in third-party transports like MongoDb, CouchDb and Redis. The additional transports are written by the members of Winston Community.
Moreover, there are different levels of a logger, set up in order of their priority in ascending order, specified by proposed standard of RFC 5424 in 2009.
[Pictorial Representation of Levels ](https://excalidraw.com/#json=ng5wxDOvU6v9HGlyYSjrq,yjd2OOWba2tFrzQh-lZtDQ)
## Setting Up Winston on Machine
Winston is available on npm to download and it is available to use on-the-go for those are looking for logging solution in their project.
```bash
npm i winston
```
Upon successful installation of winston, we can proceed further with importing the library in our project to use it when required. It will be imported and automatically an object will be created that will come into use to access methods and attributes which are part of the object.
```javascript
const winston = require('winston');
```
## Creating First Logger
Once we are set up with installation and import part of Winston, we can proceed with creating our logger. We have a function at our disposal that is assist in creating a logger with all the necessary properties feeded in the passed object.
```javascript
const logger = winston.createLogger({
transports: [
new winston.transports.Console(),
new winston.transports.MongoDB({
"db" : "mongodb://localhost/user"
})
]
});
```
As mentioned in the above code, logger is created with set of transports given in an array, however in program, transports can be added, removed or clear as per developers requirement.
```javascript
const file = new winston.transports.File({ filename: 'combined.log' })
logger
.clear() // Remove all transports
.add(file) // Add file transport
```
## Implementing Winston for Logging in a File
To obtain error logs in a file transport, we would be taking example of a full-fledged backend application based on Route-Controller-Service-Model Architecture.
Initial step comprises of creating a file transport in the `index.js` file.
```javascript
winston.add(winston.transports.File, { filename: "root.log"})
```
Now that we have our transport setup for the file named root.log to get the logging performed. We wireframe the connectivity in routing file named `route.js`.
```javascript
const express = require("express");
const app = express();
app.get('/', ()=> {
throw new Error("Logging Error to the File");
})
```
Lastly, the invoking of error is performed that appends the error log to the file.
```javascript
module.exports = (err, req, res, next) => {
winston.error(err.message, err);
res.status(500).send("Crashed into error");
}
```
## Implementing Winston for Logging in a MongoDB Collection
On instances, we come across errors that we fancy storing in our database instead of writing them to out files or console. We can move to store them as a MongoDB document in our collection specified.
An additional winston-mongodb package is needed to work with the database.
```bash
npm i winston-mongodb
```
Similar to logging in a file, create a MongoDB transport in the `index.js` file.
```javascript
winston.add(winston.transports.MongoDB, { db: "mongodb://127.0.0.1/test"})
```
The code for route and error logging can be the same as mentioned in section for logging for file but results can be altered on the basis of level provided and transport method picked.
## Takeaways
- Winston is used to log errors.
- Winston offers multiple transport, place where log is stored.
- Winston offers flexibility when it comes to writing logs.
- Core transports that are bundled with Winston are Console, File and Http.
- Third-party transports includes MongoDB, Redis etc.
- Transports can be cleared, added or removed.
- Levels can be set for log o | alimalim77 |
1,877,506 | How to make Openbox look good with ease? | I started using Linux a few years back now. In my learning path, I encountered myself with hundreds... | 0 | 2024-06-05T05:40:20 | https://dev.to/jr20xx/how-to-make-openbox-look-good-with-ease-554o | linux, openbox, customization | I started using Linux a few years back now. In my learning path, I encountered myself with hundreds of possibilities to do whatever I wanted to do at several aspects, including the chance to get a system that looks how I want it to look. I am the kind of user who like to give a personal touch to what I use and, in the past, that wasn’t easy for me to do with my desktop.
When I finally was able to switch to Linux, I encountered myself with a pretty powerful combination: Openbox + Picom + tint2 + jgmenu; and when I finally gave them most of the personal touches I always had in mind, I made [a tutorial at Medium](https://medium.com/@jr20xx/2fbe6ade855a) for users like me that may want to have a desktop that looks both good, minimalistic and functional and don’t know exactly where to start. I initially wrote this article at Medium, but now I've decided to give it a shot here as well. All the settings I’ll provide here were done by me after a process of trials, errors, frustrations and successes while reading the guides to use the pieces I putted together to get to the results I’ll share. Everything is customizable beyond the customizations I’ll expose here and I encourage you to do some modifications on your own. The process of creating something as personal as your own desktop with your own hands can be a funny and gratifying process.
## What is Openbox?
At the main page of its official wiki, Openbox is described as it follows:
> Openbox is a highly configurable, next generation window manager with extensive standards support.
> Openbox lets you bring the latest applications outside of a full desktop environment. (…) With support for the latest freedesktop.org standards, as well as careful adherence to previous standards, Openbox provides an environment where applications work the way they were designed to.
> Openbox is a highly configurable window manager. It allows you to change almost every aspect of how you interact with your desktop and invent completely new ways to use and control it. It can be like a video game for controlling windows. But Openbox can also be kept extremely simple, as it is in the default setup, meaning that it can suit just about anybody. Openbox gives you control without making you do everything.
Openbox can be used as a replacement of the window managers on desktop environments like XFCE and Mate or it can also be the default one at LXQt (or at its predecessor: LXDE). But one of its most noticeable features is that it can be also used as a standalone solution without any desktop environment at all.
The latest stable version available of Openbox is the 3.6.1 and it was released in 2015. Openbox is open source and its source code can be found in [its GitHub repository](https://github.com/Mikachu/openbox/).
Its installation process is pretty simple and it can be found at the repositories of nearly every distro available nowadays. If you need help to install it or you want to get more info about it, one of the best places to get the help you may need can be [its official wiki](http://openbox.org/wiki/Main_Page) or [the Arch wiki](https://wiki.archlinux.org/title/openbox).
## What is Picom?
Picom is a lightweight standalone compositor created for the X Window System. It is a fork of [Compton](https://github.com/chjj/compton) (which is a fork of [xcompmgr-dana](https://web.archive.org/web/20150429182855/http://oliwer.net/xcompmgr-dana/), which is also a fork of [xcompmgr](https://gitlab.freedesktop.org/xorg/app/xcompmgr/)) and it is suitable for use with window managers like Openbox that do not provide compositing effects on their own. If you want to learn more about its history, then you should visit [this page](https://github.com/yshui/picom/blob/next/History.md) or, if you are interested in knowing a bit more about it, you can check [its page on the Arch wiki](https://wiki.archlinux.org/title/picom).
Picom is also open source and you can find its code at [its GitHub repo](https://github.com/yshui/picom). The version of Picom used for this tutorial was the 10.2–1 version.
## What are tint2 and jgmenu?
At [its Arch wiki article](https://wiki.archlinux.org/title/tint2) you can find that tint2 is described as a simple, unobtrusive and light panel for Xorg. It can be configured to include a system tray, a task list, a battery monitor and more. Its look is configurable and it only has few dependencies, making it ideal for window managers like Openbox that don’t come with panels to show action icons and/or tasks. It is open source as well and you can find its source code at [its GitLab repo](https://gitlab.com/o9000/tint2).
On the other hand, as you can read at [its GitHub repo](https://github.com/jgmenu/jgmenu), jgmenu is a simple, independent and contemporary-looking X11 menu, designed for scripting, ricing and tweaking. It is hackable, has a simple code base and does not depend on any toolkits such as GTK and Qt, but uses cairo and pango to render the menu. It can optionally use some appearance settings from XSettings, tint2 and GTK; and it has UTF-8 search support.
The version of tint2 used for this tutorial was the 17.0.2 while, in the other hand, the version of jgmenu used was the 4.4.1.

## What settings to use?
### Settings for Openbox
Whether you choose to start Openbox from a display manager or not, the result will always be the same when it starts on its own. You’ll always get a black screen without anything else than a menu that appears when you right click anywhere inside of it… and it is completely normal. That is just the starting point and the goal of this guide is precisely to help you to turn that black screen into a good looking workspace.
The first thing you need to do is to install additional tools that we will use later like [ObConf](http://openbox.org/wiki/ObConf:About) (to configure basic settings of Openbox), [feh](https://feh.finalrewind.org/) (to set the wallpaper), [cbatticon](https://github.com/valr/cbatticon) (to have a battery icon for the system tray), [volumeicon](https://github.com/Maato/volumeicon) (to have a volume control applet available) and a network manager applet like, for example, [nm-applet](https://gitlab.gnome.org/GNOME/network-manager-applet).
After that, you need to set up the list of applications that will run automatically when Openbox starts. There are, basically, two ways of doing this: one is modifying the Xorg autostart file and the another one is modifying the autostart file of Openbox itself. Either method you choose, the modifications are almost the same since both files use a similar format to specify the programs to load with Openbox; though I recommend to use Xorg autostart file specially when you don’t use any display manager at all and use Openbox’s autostart files when you do use a display manager.
If you choose to modify the autostart file of Openbox, just open or create the file **~/.config/openbox/autostart** and paste the following inside of it:
{% embed https://gist.github.com/jr20xx/13b48ad102b55bbb38f6a9c5d308810b %}
If you had to create the file, don’t forget to make it executable (just to prevent any issue) by executing:
```bash
chmod +x ~/.config/openbox/autostart
```
But if you choose to modify the autostart file of Xorg placed at your home directory instead, just open the **~/.xinitrc** file and put the following lines at the end of that file:
{% embed https://gist.github.com/jr20xx/19640ae192fa41fbea8ab285a9feecb3 %}
Remember that, as I’ve said, I strongly recommend you to use the Openbox’s autostart file when you use a display manager. I haven’t tested this last variant when a display manager is in use and I suspect that some issues may appear in that kind of scenario.
After that, you need to set up other aspects of Openbox like the theme you will use for it.
This part takes a little history time. I used Linux Mint in the past. It was the first distro I used for a long period of time and loved the Mint Y themes very much. Then I started using Openbox and I never was able to find themes for Openbox that somehow recreate how Mint Y themes look; so after a few months I came with a _decent enough_ understanding of how Openbox themes are made and I created a Python script to generate themes for Openbox that look somehow similar to Mint Y themes. That script is still a work in progress, but it works decent enough for me at the moment I’m writing this; and you can find it following this link to [its GitHub repo](https://github.com/jr20xx/Mint-O-Themes).
I currently use the dark red variant of the themes I created, but you can pick any other theme of your choice to set up Openbox using ObConf from the generated themes or from other sources like, for example, [this GitHub repo](https://github.com/addy-dclxvi/Openbox-Theme-Collections), [this webpage](https://www.box-look.org/browse?cat=140&ord=latest) or from the following [archived website](https://web.archive.org/web/20050325235134/http://www.starbreaker.net/linux.php?page_id=openbox3). Now, to ease the process, I’ll just paste here the content of the file **~/.config/openbox/rc.xml** I have created. That file is where Openbox stores and reads its settings, and the content of mine is the following:
{% embed https://gist.github.com/jr20xx/04de80a0a975ed66cf3b27917d17ea2a %}
### Settings for tint2
As you may have noticed in the initial screenshot, I use two panels: one placed in the bottom of the screen and another one on top. I always use the top panel to place the applets, the clock and the action buttons to shutdown the computer, reboot it or finish my session; and then I leave the second panel to add a button to open the applications menu, show the list of running tasks in the middle of it and put a button to minimize/restore running apps. To achieve that with tint2, we only need to start two instances of it with different settings.
The first settings file you’ll need to edit is the default one. Just open **~/.config/tint2/tint2rc** and replace its content with the following:
{% embed https://gist.github.com/jr20xx/b1a515a34bb8b99ffe012a2425003c61 %}
To finalize the configuration of the bottom panel of tint2, you’ll only have to place an image icon at your home directory with the name **ic_menu.png**. That picture file will be the source for the image that will be showed in the button of the panel to show the applications menu.
After that, you need to define the settings for the top panel. As you may have noticed after reading the list of programs that will run with Openbox, the file you need to create and edit is **~/.config/tint2/tint2rc_top**. Just create it, open it and paste the following inside of it:
{% embed https://gist.github.com/jr20xx/655bcf210086a2cfbe8a7e5700082a7c %}
### Settings for jgmenu
When you read the guides to set up jgmenu, you will find that it is pretty customizable and that you can give your own touch to it with ease. In my case, as I use a dark red theme for Openbox, I setted it to match that theme; but you can make it look the way you want by just following the [guides to set it up](https://jgmenu.github.io/manual.html).
My current setup for jgmenu requires three files. The first file you need to create or modify is **~/.config/jgmenu/jgmenurc**. You only need to copy and paste the following lines inside of it:
{% embed https://gist.github.com/jr20xx/93c554891392e2b038fb368dd038f168 %}
The next file you need to create or modify is **~/.config/jgmenu/append.csv**. Then just replace its content with the following:
{% embed https://gist.github.com/jr20xx/1056ffe6a6c8e171d173d5b3a13074ba %}
After doing that, the last file you need to create is **~/.config/jgmenu/prepend.csv** and, then, just replace its content with the following:
{% embed https://gist.github.com/jr20xx/df1a68ad0aebab6ec713f82c039b023b %}
What we just did was to define the settings of jgmenu while adding some special items at the top and bottom parts of the menu that jgmenu will render. In the **~/.config/jgmenu/append.csv** file is where we define the set of stuffs that will be showed in the bottom part of the rendered menu while at the **~/.config/jgmenu/prepend.csv** file we define the stuffs that will be showed at the top part of the rendered menu. In this case, we are adding a search box on top of the menu while placing a button to finish the session and grouping other buttons to suspend, reboot or shutdown the computer from the menu on the bottom.
### Picom settings
I left Picom as the last one because is the one I think that will cause more _“troubles”_ outside of Arch. Even when its settings are almost the same everywhere, if you don’t use Arch, I truly recommend you to read the documentations of the distro you are using to find out the version they are currently distributing in their official repositories and find information of the settings available there for Picom. You will also have to read the docs and experiment a bit with the backends they provide to get to the best result for you. Another thing that you must have in mind is that the settings I’ll place here were made while using the newest versions of the backends and that some issues may appear if you use them with the legacy backends.
To set up Picom, all you have to do is to create a file named picom.conf and place it either at the **~/.config** directory or at the **~/.config/picom** directory. The directory you choose to place the file doesn’t make much difference, but it is usually located at **~/.config**.
Once you’ve created the picom.conf file, just open it and put the following lines inside of it:
{% embed https://gist.github.com/jr20xx/68ac89576916faebd046b7a676ca470c %}

## Additional recommendations
By following this guide and performing the aforementioned configurations, we are able to get a pretty good looking, minimalistic and functional workplace indeed; but we may be still missing some components like, for example, a file manager app, an application to configure GTK themes, a text editor, a calculator, a web browser or a media player. For those tasks and any other remaining customization tasks like, for example, customizing the mouse pointer, all I can say is that I encourage you to find the solutions that suits you the best.
Just in case you wonder, I personally use [Nemo](https://github.com/linuxmint/nemo) as file manager. I also use the GTK+ 3 version of [LXAppearance](https://wiki.lxde.org/en/LXAppearance) to configure the GTK themes, [Xed](https://github.com/linuxmint/xed) as text editor, [galculator](http://galculator.sourceforge.net/) as calculator app, [Chromium](https://www.chromium.org/Home) is my web browser, [SMPlayer](https://www.smplayer.info/) is my media player and I haven’t customized anything else… yet.
I hope this guide has been helpful for you and, please, always have in mind that the customizations I shared here were done by me to build my own environment and I decided to share them as a guide for people who may not know how to turn Openbox into more than just a black screen, for those who may want to customize Openbox quickly and for anybody else that may find here some piece of information they may find helpful. Feel free to modify the settings you find here as much as you want and, please, leave an upvote here and/or at [the original Medium article](https://medium.com/@jr20xx/2fbe6ade855a) if you found this article helpful. | jr20xx |

## Why logic in views is a bad idea?
The main reason not to put the complex logic into your views is, of course, testing. I don’t want to say that it is impossible to test logic defined in views, but it is much more complicated. And, as a very lazy person, I don’t like doing an extra work.
The second reason is that views should have as little embedded dynamic code as possible. This gives us much cleaner code which is easy to modify and maintain.
In our company we have a few simple conventions about logic in views:
* The ***Use only one dot*** rule. Which is also known as the [Law of Demeter](http://en.wikipedia.org/wiki/Law_of_Demeter#In_object-oriented_programming). You should try to avoid expressions that are accessible with more than 1 dot. For example,@user.current_ledger.articles. It is obvious that you should make this call in controller, not in views.
* Don’t hit database in views. This mistake is just as obvious as it is common. You should not make database calls inside views.
* Avoid the variables assignments inside views. You should not make any computations in the views. They should only display already computed values.
There are some common practices to resolve logic-less views problems. Let’s take a closer look.
## What is wrong with helpers?
Rails gives us a powerful tool named helpers. You can define methods inside those modules and then magically use them inside your views. Cool! We can put logic inside those modules and forget about our problems!
Here I will give you the list of what I don’t like in helpers:
* Helpers are often being used to retrieve data from the db. An example: visible_comments_for(article)
* A big number of helpers are generating html tags with ruby. In this case when I need to modify the markup, I will have to modify all the helpers, not markup files. The helpers should format data, not generate markup.
* It is not obvious what is the receiver object of the helper method. This call prepare_output(article.body) reminds me about global procedures and functions. C’mon, this is an OOP world, why the stuff like that is still alive here?
* Helper functions are defined inside modules, so we don’t have the power of inheritance (we can mix modules with modules, but that is not the same).
* It is hard to track helpers dependencies on another helpers. I’ve seen a lot of helpers that are calling another ones not from their native module.
* The testing is much easier, but still not perfect.
## Fat models
This is not an option in the real world, but it deserves to be mentioned in this list. We can encapsulate all our views logic inside models. Of course, this will lead us to 1000 lines of unmaintainable code. But, finally, we can test it easily and have a working inheritance.
To avoid model code overgrowth we can define all views-related logic in modules and then include them into model class. But still, we have one monolith class with hundreds of public methods.
## Decorators
To separate views-related logic from models folks from OOP world are using the [Decorator pattern](http://en.wikipedia.org/wiki/Decorator_pattern). This pattern allows to add behaviors to a single object. In rails world we have a few gems implementing this pattern. The alive one is [draper](https://github.com/drapergem/draper) gem. It has a cool DSL not only for decorating your models, but also for decoration of their relations. So, you can build the whole decorators tree using simple Model.decorate method.
The decorator pattern was designed for replacing your object with the new one with additional functionality, so you can use your decorator objects as you would use your models objects.
The testability of this solution is very high. You can instantiate decorators with stubs without hitting the database in the most of your test cases at all.
The usage of decorators is the cool and clean solution. But what if I need some really complicated logic to build the view that is based on 2 non-relative models? What if my logic is not related to models at all? The second name of the Decorator pattern is Wrapper. What should I wrap?
## View object
I present to you *View Objects*! *The View Objects* concept is simple. All the logic you need in views should go into the *View Objects*.
*The View Object* sometimes can be the simple decorator. This happens when your view logic depends only on the model data. In this case you need to “add custom behavior” to an object, this is where decorator suits perfectly:
```ruby
class DiscussionViewObject
attr_reader :discussion
delegate :name, :created_at, to: :discussion
def initialize(discussion)
@discussion = discussion
end
def name_with_time
@_name_with_time ||= created_at.strftime('%Y/%m/%d') + name
end
end
```
```html
<div class="discussion-item">
<%= discussion.name_with_time %>
</div>
```
The second case is when your view logic is based on several not connected models or even on the request. When you are facing this problem the *View Object* can implement the ***“Presenter”*** part of the ***MVP*** pattern.
The ***MVP*** (*Model-View-Presenter*) is a pattern well-known in *C#*/*Java* world. It is mostly used to build interfaces (views, in our case). It allows us to separate concerns: the model encapsulates domain logic, the presenter takes all the view logic and the view [knows nothing](http://youtu.be/Pkyy57iMaB0).
The main difference between ‘classic’ presenters and our ones is that we still have a controller that receives user’s inputs and commands.
Here is the *View Object* that implements the logic from the 2 unrelated models:
```ruby
class IssuesPresenter
attr_reader :issues, :filters
def initialize(issues, filters)
@issues, @filters = issues, filters
end
def has_selected_filters?
filter.any?
end
def all_issues_are_resolved?
issues.all?(:resolved?)
end
end
```
```html
<%= if @issues.all_issues_are_resolved? %>
<%= if @issues.has_selected_filters? %>
All selected issues are resolved.
<% else %>
All issues are resolved.
<% end %>
<% end %>
```
The *View Object* allows you to build complex page logic using simple view logic wrappers.
As in the case with decorators, you should instantiate the view objects at the end of your actions. The controller should process given parameters, select necessary models, instantiate view objects and then give control to view (render it).
The view can use view objects methods along with models methods if that is necessary, but I don’t recommend mixing them inside one view.
You can have as many view objects as you want. When you need some unique logic, you will have 1 view object per action and when you have the repeating logic, you can reuse your view objects in multiple actions.
But you should not stick to your actions. For example, if one of your layouts has a complex logic depending on the current controller state, then you can create *View Object* for it and instantiate it in actions where you are using it (with before_filter for example).
The main pros of using this solution are:
* *View Objects* are the [PORO](http://blog.jayfields.com/2007/10/ruby-poro.html), so you can use all cool OOP features ruby has: mixins, inheritance, etc.
* *View Objects* are not bound to models directly, so you can use them when the decorator does not suit properly.
* Test *View Objects* logic is as easy as test ruby classes. As in decorators solution, you can feed *View Objects* with stubs to increase the tests speed.

1,877,538 | Quality software services for a thriving business | Nowadays, businesses have found their place in the online environment. They may want to increase... | 0 | 2024-06-05T05:37:20 | https://dev.to/growwwise/quality-software-services-for-a-thriving-business-c33 | Nowadays, businesses have found their place in the online environment. They may want to increase their visibility and make themselves known or sell products and services directly from their website. But in a large pool of industries, entrepreneurs use applications, programs, or software through which they carry out their activity and offer services and products for their clients.
The creation and implementation of a software or an application is not an easy process and may require the use of professional help, like [backend development services](https://intelligentbee.com/back-end-development-services/). This represents just one part of the process, as the other part is about designing and improving the resulting product for users.
If you want these types of services for your business, you should search for an experienced developer that can create a functional and personalized solution. Also, because the programing is done using databases, you have to make sure that the developer takes security measures to protect the servers from online attacks.
## A software that fits your business needs
Regardless of the type of business you have, you may want to improve the way you deliver your products and services to your clients. For example, you can develop a custom software for payment options, and in this case, you can work with a [custom software development company](https://intelligentbee.com/custom-software). This type of company can create a tailored solutions that can help you achieve your business goals.
What are the benefits of a custom software solution
• It can be improved and modified very easy
• It can integrate with other systems or software that you use
• It is secured and protects your databases
• It does not require ongoing licensing and other future fees after the initial investment
Custom software solutions can help you more than the ones that already exist, which you should adapt to your existing systems. That’s why it could be much more effective to hire a company specialized in this type of service, to create a software that perfectly fits your business needs.
The first step in creating this software is to generate ideas according to your business needs and characteristics. The process also includes collaboration with the client in order to keep him informed about every step that is taken. Then, the developers combine their creativity with the best practices in the industry and ensures a transparent work environment to achieve client requirements.
### Creating a friendly interface for your users
Browsing a website or an application should be a very easy and comfortable experience. To make this possible, you may want to use professional [front-end development services](https://intelligentbee.com/front-end-development-services) offered by a specialized company. This focuses on the parts that users interact with, while back-end services focus on the functionality and the logic of the app or software.
What are front-end developers responsible for?
1. Meeting the User Experience and User Interface standards
2. Fixing issues with different pages
3. Increasing the loading speed of the website
4. Validate any elements that require user input
A very important part of the process is creating a responsive design. This means that the website or the application works seamlessly on multiple devices, such as desktop or smartphones. Also, this development service can create applications that can work for various operating systems.
Working with a company specialized in software development can be very useful for your business, because you can benefit from quality and professionalism. The developers within this company use innovative tools and methods to ensure that the software works properly.
### Why should you hire both types of developers
According to the information presented earlier, you have found out how can you create quality and performance when it comes to software development. There are different services that you can use separately, but it would be best to combine them for a better result.
Working with both types of developers could be very effective for your success. One of them creates the design, the other one builds its functionality. Both of them have to make sure that every step they take, they take it to create a website or an app that works perfectly.
Both of them are well prepared and qualified to deliver great results, using high-quality methods and practices. Also, both of them conduct rigorous testing to make sure that the software works correctly, and the user interface fit the requirements.
#### Grow your business and fulfill your clients expectations
In the end, using professional software development services could help your business thrive and evolve. The quality of your website or app can be improved and you can boost your traffic and clients.
Collaborating with a front-end developer can help you create a good-looking interface for your website, while a back-end developer can make sure that your website or app function accordingly.
Both of them are important in this process and that is why you could choose to hire both a front-end and a back-end developer. Their services could boost your success and they will make sure to maintain that success in the long term.

## How To Name Variables And Methods In Ruby
> # What’s in a name? that which we call a rose
> #By any other name would smell as sweet.
> # *― William Shakespeare, Romeo and Juliet*
Junior developers often struggle to choose good names for variables and methods they write. Or even dismiss the need in proper names without any struggle at all. I blame computer science education with its strange love for one-letter variables (or, when all letters are taken, then one-letter-and-a-number).
I remember being taught to declare variables a, b, c or s1, s2, s3 or functions f1, f2, and explain their purpose in comments. (Excessive use of comments to justify unreadable code is another problem area of CS education)
## Now I know my ABC’s next time won’t you sing with me
One-letter names are bad because they don’t tell anything except *“here’s this particular address in the memory where I store some value”,* and a reader of the code where such name is used has to exert mental effort on finding and keeping in mind what the name associated with. At first choosing, good names also take mental effort, but it eventually pays off, unlike the efforts of those who try to figure out unmeaningful names you wrote.
Naming variables by the first letter of the concept they represent is a good start, but it shouldn’t stop there.
```ruby
# bad
c = post.comments.where(published: true)
m = c.max_by(&:rating)
# good
post_comments = post.comments.where(published: true)
top_rated_comment = post_comments.max_by(&:rating)
```
Note how the second line in a *“good”* example tells you the complete story without the need to look at the first line. While in the *“bad”* example, there’s no way to figure out what happens in the second line without looking at the first one.
There are some exceptions, like using e for an exception in rescue-block, or i for a numeric index, or f for FormBuilder instance inside a view, or k, v for key-value pairs (although this one is often misused).
## The naming of cats is a difficult matter
Like cats in the famous poem, entities in our programs can be described by different names. It’s important to choose, depending on the context, one that represents the entity best for this context.
Consider this report on the coat patterns of cats in our database:
```ruby
hash = Cat.group(:coat).count
# => { 'tabby' => 99, 'black' => 11, 'calico' => 20, 'tuxedo' => 1 }
hash.each do |k, v|
puts "Coat: #{k}"
puts "Count: #{v}"
puts "-" * 10
end
```
What’s wrong with that? The result of the query is indeed a Hash, and we iterate over its keys and values (and it’s okay to call them k, v). Right?
No. What’s wrong is that we named the variables by properties, irrelevant to the context. The line
```
hash.each do |k, v|
```
tells us we’re iterating over some Hash while the following line implies that this hash has some “coat” for keys (still not clear what this is without looking at the top of the code), and the line after that tells that the values are some “count”.
But if we choose relevant names, each line tells the full story:
```ruby
cat_counts_by_coat = Cat.group(:coat).count
# => { 'tabby' => 99, 'black' => 11, 'calico' => 20, 'tuxedo' => 1 }
cat_counts_by_coat.each do |coat, count|
puts "Coat: #{coat}"
puts "Count: #{count}"
puts "-" * 10
end
```
So, name your variables not just by what they represent, but by what is relevant for the context.
Following this advice, you may end up with really long and specific names, like neutered_cat_without_flees_counts_by_coat, because every part of that name is important for the context of your too-detailed report.
Such long names are actually a good thing, but not because it’s good to have such long names (it’s not), but because they indicate a problem with the context. They show that the class or method is trying to handle too many things at once, and you have to split it into smaller parts with as little dependencies as possible.
## Though this be madness, yet there is method in ‘t
> # *It may be necessary to use methods other than constitutional ones*
> # *― Robert Mugabe*
The first and the only president of Zimbabwe justified the use of unconstitutional methods in his struggle to move away from white minority rule of Rhodesia, but it turned out dreadful for the people, resulting in total corruption and poor economy.
If methods in your code will be unconstitutional (breaking coding conventions and denying common sense), you will also end up with a poor and corrupt code base.
So the general rules of meaningfulness should also apply to method names, but with several caveats.
Instance methods can be loosely divided into four groups: *accessor*, *mutator*, *imperative* and *predicate*.
**Accessor**(getter) methods return properties of the object or some representation of them. They are best named by the property they return. That’s usually a noun with some optional adjectives or possessive nouns. For example, User#first_name, Book#rating, Report#results.
Properties that describe some action that was performed on the entity are named with a verb in simple past tense, preposition and optionally a noun when it’s not evident by whom was the action performed. For example Account#created_at, Post#published_by, Article#referenced_in_indices. In some languages, specifically Java, such methods are prefixed with get_, but in Ruby, it’s not appreciated.
Also, note that method names take the class name into account, so if the class is named User, there is no point in having a method named user_email in that class. It’s just User#email. It makes sense to have an entity as a part of the method name only when this entity is represented by another class, or when it refers to other instance of the class, not the same we’re calling the method on. For example, Book#author_name, User#invited_by_user.
**Mutator **(setter) methods are ones that used to assign properties of the object. In Java, they are usually named as set_<property_name>, but in Ruby, it’s just <property_name>=(value). Namely, User#email=(value), Comment#body=(value) etc.
If your mutator method has to accept two or more arguments, you can’t have a method ending in =. Well, technically you can, but to invoke it you’ll have to use metaprogramming tricks. In that case, you have to strongly reconsider your approaches, and why you need a setter with multiple arguments in the first place. You probably need to create a separate class for that property at this point. Again, a good choice of names guides your application design.
**Imperative **methods either change some state (of the object, the app or even the outside world), or return some new data or transform existing data without mutating it.
They are usually named with a verb or a phrase in an imperative mood. Like Report#generate, Document#write_to_file(path), MessageService#send(from, to, body).
When you want to provide both a *“safe”* and a *“dangerous”* way of doing the same thing, name the *“dangerous”* method same as the *“safe”*, but with an *“!”* (exclamation mark) at the end.
Examples of *“safe”* and *“dangerous”* methods are Array#sort and Array#sort! from Ruby Core library, where the first method returns a new sorted array, leaving the original intact (which is considered *“safe”*, unless you take your RAM very seriously). And the other mutates the original array (which is in turn considered *“dangerous”*, because you may lose some data).
Other such examples are #update and #update! from ActiveRecord::Persistence, first one returning false in a case of validation errors and saving those errors in the model, and the second one raising an exception if the record is invalid. But if you don’t provide safe alternatives and all methods in the class are dangerous, there’s little point in using exclamation marks then.
**Predicate **methods always return *boolean*. They describe the object status in a yes/no manner, or if it’s a private method they can contain a named part of some long conditional. Their names should always end with a question mark.
Grammatically the names can be anything from adjectives like TrafficLight#green? to full-fledged sentences like WeatherService#should_i_take_an_umbrella?.
The general rule of thumb for picking a name for a predicate method: it should be something you can read in a question intonation, and it would make sense.
Of course, there may be methods that don’t fit into any of these four categories, and we did not cover class methods here at all, but in general, it’s all the same: the name should make sense and it should contain just the right amount of context to be clear — not more and not less.

## 4 Steps to Bring Life into a Struggling Project
At the initial stages of a new business or a startup, when the future is unknown, people often opt for short-term solutions in product development. These short term solutions often result in hiring and changing contractors, delivering code with [technical debts](https://martinfowler.com/bliki/TechnicalDebt.html), constant requirements changes.
When the product finally starts getting traction by acquiring users or paying customers, the business is now ready for investment and the product is ready to scale… or not?
The short term trade-offs made once often come at a high price. With technical debts, reducing the velocity of delivering new features, the business now has a dilemma. But does the business drop the initial product version and begin a re-write that takes into consideration all the new knowledge? Or does the business continue to support older product and fix its mistakes? These are hard decisions to make: not only for the business owners, but also investors, employees, and everyone else involved.
If the business decides to invest in the improvement and growth of its existing solution, common project issues that might arise can be categorized as follows:
1. [Darkness](#72c7): No plan, and no one knows what needs to be done.
2. [Confusion](#fe38): Lack of documentation and process specifications.
3. [Rust](#8e74): Developers are extremely slow to deliver work.
4. [“Deja Vu”](#15b9): A huge number of repeated bugs exist in the product.
To move the project forward, each category needs to be permanently eliminated.
## Eliminating The Darkness
### Signs of the Darkness Problem:
1. Can not see progress in real-time;
2. Deadlines keep shifting;
3. Developers do not understand the big picture, and cannot decide how to approach the new tasks.
The practices we use to solve this are based on [Lean](https://leankit.com/blog/2015/05/welcome-to-the-new-lean/) and [Kanban Methodology](https://www.atlassian.com/agile/kanban). They are simple, scalable, and are used by the best development teams across the world.
Addressing the problem and introducing the methodology, we start with [Kanban Board](https://leankit.com/learn/kanban/kanban-board/).
At a quick glance, everyone has transparency in the project and can see the following:
* What state each task is in
* Who is working on what
* What work is blocked
* Where the bottlenecks are
**Our solutions:** [GitHub](https://github.com/) with [Waffle Integration](https://waffle.io/)
## Eliminating The Confusion
### Signs of the Confusion Problem:
1. Setting up New Production, Staging or Development instances takes too much time, especially for people who are new to the team;
2. There are “experts” on your team who “are the only ones who understand the production configuration”.
We expect that all development processes should be clear and simple for anyone, regardless of their expertise level. Clear documentation ****is an essential way of ensuring developer productivity, ease of maintenance, and project longevity.
When we ensure the processes for product delivery, all development aspects are sufficiently documented, and new team members do not require excessive guidance from their colleagues to set up development environments, understand the technologies, and start building the product. When routine tasks can be automated, we do so. For example, automatically checking a pull request for code style violations and disabling the Merge button if there are any, is far more efficient than a written instruction “check code style before merging”.
**We automated things such as:** Setting Up Environments, Running Tests, Code Style Checking, & Auto-Deployment.
## Eliminating The Rust
### Signs of the Rust Problem:
1. Delivering new features takes excessive time to build, integrate and verify;
2. There is a long list of partially done features.
In software development, Rust is when you have stale issues that have not been updated for some time or issues that you cannot deliver.
### Break Big Tasks Into Smaller Pieces
Creating smaller, more manageable tasks allows the project team to avoid stress and procrastination and focus on high-quality development, testing, and collaboration.
We should not hesitate and split tasks in the middle of work.
**Our constraint:** 2 days per task
### Setup Work In Progress Limits
In combination with Kanban, we can eliminate Staled Code by limiting Work In Progress of team members. Work In Progress Limits helps teams focus on correct decisions, completion, and quality. Also, highlight bottlenecks in a team’s delivery pipeline before a situation becomes dire.
**Our Limits:** Each Person focuses on *2 Items only at a time.*
## Eliminating The “Deja Vu”
### Signs of the “Deja Vu” Problem:
1. The same bugs frequently reappear;
2. Changes on one part break another part of the application.
This is incredibly frustrating. Persistent bugs not only frustrate customers that run into them, but frustrate team members who constantly address them.
### Resurrect Automated Testing and Continuous Integration
Unit and small integration tests are one of the best things you can do to reduce regression, which all this should be combined with Continuous Integration. In addition, all new changes need to be covered by tests.
In addition, using a [TDD](https://martinfowler.com/bliki/TestDrivenDevelopment.html) approach can easily make changes to application — all without fear of ‘breaking’ the application and hamstringing their daily operations.
**Out tools:** [CircleCI](https://circleci.com/)
### Verify New Changes
Just like authors of novels, authors of software need their peers to review their work in detail to ensure their work is successfully published.
[Code Review](https://www.atlassian.com/agile/code-reviews) is crucial and has been repeatedly shown to accelerate and streamline the process of software development.
With Code Review, team members can verify the new changes under an isolated testing environment. It makes verification much easier and the developer will not have to review broken, co-mingled code from other members’ changes on staging.
As a result, we can eliminate several problems and:
* Deliver defect-free, readable and well-documented software;
* Facilitate the sharing of knowledge between developers.
**We found useful:** [Heroku Review App](https://devcenter.heroku.com/articles/github-integration-review-apps) and [GitHub](https://github.com/)
## Summary
These outlined practices are very simple and easy to integrate, but at the same time produce lasting and impactful results in short time.
These recommendations are amongst many requirements when integrating effective lean and agile practices. With an effective development pipeline, healthy engineering teams can be built.

1,877,532 | Create an Astro blog from scratch | Astro is a web framework for creating content-driven websites. It allows you to build extremely fast... | 0 | 2024-06-05T05:24:12 | https://dev.to/ramkarthik/create-an-astro-blog-from-scratch-5870 | astro, javascript, tutorial, beginners | Astro is a web framework for creating content-driven websites. It allows you to build extremely fast websites. It is perfect for building blogs and we are going to do exactly that. We are going to build an Astro blog from scratch.
You can find the complete code here: [https://github.com/Ramkarthik/astro-blog-tutorial](https://github.com/Ramkarthik/astro-blog-tutorial)
This is the blog we are building from scratch: [https://quick-astro-blog-tutorial.vercel.app/](https://quick-astro-blog-tutorial.vercel.app/)
We will be going over the steps below to build this blog:
0. Create an Astro project
1. Add some basic styling
2. Create a layout
3. Set up default website configurations
4. Create an About page
5. Create a Nav header
6. Create a folder to add the blog content (the easy route)
7. Use Content Collections for our blog
8. Setting up the dynamic routes for our blog
9. Getting Markdown content from collection entry
10. Create a blog listing page
11. Using our first Astro Integration to add SEO
12. Create an RSS feed for the blog
13. Add Sitemap and robots.txt file
14. Preparing for deployment
15. Next steps
Before we start, you want to make sure you have Node.js installed. Astro recommends using `v18.17.1` or `v20.3.0` or higher. ( `v19` is not supported.)
### 0. Create an Astro project
Open Terminal and navigate to the folder where you want to create the blog and run this command to create an Astro project:
```shell
npm create astro@latest
```
It will ask you a couple of questions:
```shell
1. Where should we create your new project? ./name-of-your-project
2. How would you like to start your new project? Empty (You can use the blog template here but this is to learn how to set up one from scratch, so we will choose the Empty template)
3. Do you plan to use TypeScript? Yes (You can choose no if you don't want to use TypeScript)
4. How strict should TypeScript be? Strict
5. Install dependencies? Yes
6. Initialize a new git repository? Yes
```
This will create the Astro project. Navigate into the folder to run the project. Open the project in your favorite editor.
```shell
cd name-of-your-project
npm run dev
```
Go to https://localhost:4321 and you will see the page displaying **Astro**. If you chose the blog template in step 2, you may see a different page.
Before we get started, let's modify the `tsconfig.json` file a little bit to make things easier for referencing different components.
```json
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@/*": ["./src/*"]
}
},
"extends": "astro/tsconfigs/strict"
}
```
Let's get started.
### 1. Add some basic styling
We can write the CSS from scratch as well or use something like Tailwind. To keep things easier, we will use one of the many classless CSS. A classless CSS styles a page based on the HTML elements instead of using class names. We are using this to make it easier for us to style the HTML rendered using Markdown. The Astro Markdown render outputs a basic HTML and using a classless CSS, we don't have to worry too much about styling each element. Classless CSS are also lightweight so our blog will be extremely fast.
There are [many classless CSS options](https://github.com/dbohdan/classless-css). For this project (and my blog), I'm going to be using [Sakura](https://oxal.org/projects/sakura/). You can use any of those options.
1. Download the CSS file
2. Create a folder named `css` inside the `public` folder
3. Paste the file and rename it to `style.css`
Now go to `\src\index.astro` and add the CSS file to the end of the `<head>` tag.
```html
<link rel="stylesheet" href="/css/style.css" type="text/css" />
```
You should see the changes already. Without adding any classes, we can see that our page is already styled.
### 2. Create a layout
Layouts are basic templates that can be shared across different pages. We want the basic `html`, `head`, and `footer` elements to be available on each page. So let's create a base layout that will store these as a template.
1. Create a folder named `layouts` under the `src` folder (`\src\layouts`)
2. Create a file inside the layouts folder named `Base.astro` (`\src\layouts\Base.astro`)
The page we are seeing now comes from the `pages\index.astro` page. This is the default page or the entry point. We will be creating both the static pages (ex: `\about`) and the dynamic pages (ex: `\blog\my-first-post`) by creating Astro pages inside the `pages` folder.
Now let's move all the code inside the `index.astro` page to the `Base.astro` page we created.
Go to `index.astro` and add the `Base.astro` layout.
```jsx:pages\index.astro
---
import Base from "@/layouts/Base.astro";
---
<Base />
```
You will notice a couple of things:
1. In Astro, you write JavaScript code within the `three dash separators`.
2. Similar to React, you can also write JavaScript alongside HTML.
If you refresh the page now, you should not see any difference because we only moved the content from `index.astro` to `Base.astro` and referenced `Base.astro` from `index.astro`.
This brings us to a new concept in Astro... **Slots**. Astro uses `<slot/>` to inject the child components.
Let's go to `Base.astro`. Not every line of code there belongs in a template, mainly the `<h1>` tag. Replace that with `<slot />`.
Go to `index.astro`, and add the `h1` tag within the `<Base>` tag.
```jsx:pages\index.astro
---
import Base from "@/layouts/Base.astro";
---
<Base>
<h1>Astro</h1>
</Base>
```
Go to the browser and you will not see any changes. What we did was move the template code from `index.astro` into `Base.astro` and use the layout.
### 3. Set up default website configurations
We need some basic information about our website that we need to display in many places. We don't want to type them everywhere. We want to store these configurations in one place and refer to them wherever we need them so that if we want to make any changes, we only have to change the configuration.
1. Create a folder named `utils` inside the `src` folder (`src\utils`)
2. Create a file named `AppConfig.ts` inside the `utils` folder (`AppConfig.js` if you don't want TypeScript)
```typescript:utils\AppConfig.ts
export const AppConfig = {
author: "Author Name",
title: "My personal website",
description: "This is my personal website",
image: "/images/social.png", // this will be used as the default social preview image
twitter: "@handle",
site: "https://yourwebsite.com/" // this is your website URL
}
```
Our website currently displays `Astro`. Let's change that to show our name from the config file we created. Let's also bring in the description and display that.
```jsx:pages\index.astro
---
import Base from "@/layouts/Base.astro";
import { AppConfig } from "@/utils/AppConfig";
---
<Base>
<h1>{AppConfig.title}</h1>
<p>{AppConfig.description}</p>
</Base>
```
### 4. Create an About page
Now that we have the home page, let's see how we can create a new page - in this case, an About (`https://localhost:4321/about`) page.
Astro uses file-based routing. Let's see some examples:
```
src/pages/index.astro -> mysite.com/
src/pages/about.astro -> mysite.com/about
src/pages/about/index.astro -> mysite.com/about
```
As you can see, there are two ways to create an About page. We will use the first approach and create a new file named `about.astro` inside the `pages` folder.
```jsx:pages\about.astro
---
import Base from "@/layouts/Base.astro";
---
<Base>
<h1>About</h1>
</Base>
```
Go to `http://localhost:4321/about` and you should see the page we created.
### 5. Create a Nav header
We now have two pages, so we need a way to link to them from our home page as well as our other pages. We will do this by creating a nav header. Since we want this header to appear on all our pages, we will add it to the `Base.astro` layout page.
Instead of adding the code for the header directly to this file, we will create a separate component (`Nav.astro`). From the React docs:
"Components let you split the UI into independent, reusable pieces, and think about each piece in isolation."
We will store all the components inside a separate folder called `components` which we will create under the `src` folder (`src\components`).
1. Create a folder named `components` inside the `src` folder (`src\components`)
2. Create a file named `Nav.astro`
Let's display our name on the left and the navigation links on the right.
```jsx:src\components\Nav.astro
---
import { AppConfig } from "@/utils/AppConfig";
---
<nav role="navigation">
<a href="/">{AppConfig.author}</a>
<div>
<a href="/about">About</a>
</div>
</nav>
```
We will style this in a minute. We only have two pages, so this approach is fine. But we will likely create more nav links like `blog`, `rss`, etc and there's a better way to manage that than adding a new line of code here with the name and the link.
Let's go back to our AppConfig.ts and add our list of pages.
```typescript:src\utils\AppConfig.ts
export const AppConfig = {
author: "Author Name",
title: "My personal website",
description: "This is my personal website",
image: "/images/social.png", // this will be used as the default social preview image
twitter: "@handle",
site: "https://yourwebsite.com/",// this is your website URL
pages: [{
name: "About",
link: "/about"
}]
}
```
We can now modify the `Nav.astro` component to get the links from the `pages` array.
```jsx:src\components\Nav.astro
---
import { AppConfig } from "@/utils/AppConfig";
---
<nav role="navigation" class="justify-between">
<a href="/">{AppConfig.author}</a>
<div>
{
AppConfig.pages.map((p, index) => {
return (
<span>
<a href={p.link}>
<small>{p.name}</small>
</a>
{index != AppConfig.pages.length - 1 && <small>|</small>}
</span>
);
})
}
</div>
</nav>
```
You might be familiar with this syntax of mapping an array and returning JSX, if you've used React before. One thing you may notice is the missing `key` property. Astro doesn't require a `key` property.
Also, notice the `class="justify-between"` added to the `<nav>` element. We will use this later to style the nav.
You won't see any changes on the website yet because we haven't added the `Nav.astro` component to our `Base.astro` layout. Let's do that now. We will add the `<Nav />` component just above the slot.
```jsx:src\layouts\Base.astro
---
import Nav from "@/components/Nav.astro";
---
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="icon" type="image/svg+xml" href="/favicon.svg" />
<meta name="viewport" content="width=device-width" />
<meta name="generator" content={Astro.generator} />
<title>Astro</title>
<link rel="stylesheet" href="/css/style.css" type="text/css" />
</head>
<body>
<Nav />
<slot />
</body>
</html>
```
If we go to `http://localhost:4321/`, we should now see the title and the navigation links. Let's style this so that the title is on the left and the nav links are on the right. Remember the `nav="class"` that we added to the `nav` element before. We will use that to style the nav.
Add this to the end of the `style.css` file:
```css:public\style.css
.justify-between {
display: flex;
justify-content: space-between;
}
```
Perfect, we have the header set up now. In case you don't see the changes, press `Ctrl+R` on the webpage to hard reload (disabling the cache). Let's move on to the blog (the interesting part).
### 6. Create a folder to add the blog content (the easy route)
We want to create a folder to store the contents of our blog. Each post will be a Markdown file. We will do the easy implementation first and then change that to match our needs.
1. Create a folder named `blog` inside the `pages` folder (`pages\blog`)
2. Create a sample Markdown file inside the `blog` folder
I'm going to create a file named `my-first-post.md`:
```markdown:src\pages\blog\my-first-post.md
---
title: My first post
createdDate: "2024-05-18"
modifiedDate: "2024-05-18"
tags: ["first-tag"]
summary: "A summary of the post"
---
This is my first blog post written in Markdown.
```
The content within the `three dashed separator` `---` is called **frontmatter**. We will later use the information from the frontmatter to display on our page.
Now go to the URL: `http://localhost:4321/blog/my-first-post` and you should see a very basic version of your blog post content. You will not see the title yet and that's where frontmatter comes into play.
### 7. Use Content Collections for our blog
Currently, we have the blog content inside the `pages` folder. We want to keep the `pages` folder for code and move our blog content to a separate folder so that we have a separation of concerns and it is also easier to manage it this way.
Astro provides an API called `Content Collections` starting from `astro@2.0.0`. To use this feature, we have to create a folder named `content` inside the `src` folder. This `content` folder is restricted for content collections and should not be used for anything else.
So let's go ahead and move our blog folder from `src\pages` to `src\content`. If you followed the steps so far, your project folder should look like this:
```
.astro
node_modules
public
css
style.css
favico.svg
src
components
Nav.astro
content
blog
my-first-post.md
layouts
Base.astro
pages
about.astro
index.astro
utils
AppConfig.ts
env.t.ds
.gitignore
astro.config.mjs
package-lock.json
package.json
README.md
tsconfig.json
```
Now the URL `http://localhost:4321/blog/my-first-post` will not work because we have moved the `blog` folder within the `content` folder.
### 8. Setting up the dynamic routes for our blog
We want the URL `http://localhost:4321/blog/my-first-post` to work again. We can see that we have the `\blog` route which means we have to create a folder named `blog` inside the `pages` folder.
Once we create the folder, we need to set up a way to handle the dynamic part of the URL, called the `slug`. In our case, the slug is `my-first-post`. But for each post, this will change.
Let's create a file named `[slug].astro` inside the `blog` folder (`src\content\blog\[slug].astro`).
For the dynamic paths to work, we need to let Astro know of the different possible paths. We do this by implementing the `getStaticPaths` function. For us to know the different paths available, we have to get each file inside the `content` folder and return the `slug`. We do this using the `getCollection` API provided by Astro via the `astro:content` module that is built-in.
The `getCollection` API works only with folders inside the `content` folder. We get the posts inside the `blog` folder, map through each item, and return the `slug` as a parameter and also the contents of each item as props. Astro has a nifty way to retrieve the props through `Astro.props`.
While we are on this file, let's add some basic HTML as well. We will use the `Base.astro` layout we created.
```jsx:src/pages/blog/[slug].astro
---
import { getCollection } from "astro:content";
export async function getStaticPaths() {
const posts = await getCollection("blog");
return posts.map((post) => ({
params: { slug: post.slug },
props: {
post,
},
}));
}
---
<Base>
<h1>Title</h1>
</Base>
```
Go to `http://localhost:4321/blog/my-first-post` and it should now work. We have successfully migrated to the `Content Collections` API.
But wait, where's the content of the post we saw earlier? We have to bring those in from `Astro.props`.
Remember the frontmatter we added to our post? Let's first define a schema so that we get type safety. We need it when we get the values from `Astro.props`.
Create a file named `config.ts` under the `content` folder (don't add it inside the `blog` folder).
```typescript:src\content\config.ts
import { z, defineCollection } from 'astro:content';
const blogCollection = defineCollection({
type: 'content',
schema: z.object({
title: z.string(),
summary: z.string(),
tags: z.array(z.string()),
createdDate: z.string(),
modifiedDate: z.string(),
}),
});
export const collections = {
'blog': blogCollection,
};
```
Once we define the schema, we have to let Astro know to generate the types. We can do that either by stopping the server (`Ctrl+C`) or by running `npm run astro sync`.
Now let's edit the `[slug].astro` file to display the blog post title. For this, we have to extract the title from Astro.props and add this to the existing `<h1>` tag.
```jsx:src/pages/blog/[slug].astro
---
import { getCollection } from "astro:content";
import Base from "@/layouts/Base.astro";
export async function getStaticPaths() {
const posts = await getCollection("blog");
return posts.map((post) => ({
params: { slug: post.slug },
props: {
post,
},
}));
}
const { post } = Astro.props;
const { title, summary, createdDate, tags } = post.data;
---
<Base>
<h1>{title}</h1>
</Base>
```
Now when you go to `http://localhost:4321/blog/my-first-post`, you should see the title from the frontmatter of the post appear.
What about the content?
### 9. Getting Markdown content from collection entry
We are writing our posts in Markdown. We want Astro to generate HTML for the markdown and display that. We do this by first using the `render()` function Astro provides and then adding that to the HTML block.
```jsx:src/pages/blog/[slug].astro
---
import { getCollection } from "astro:content";
import Base from "@/layouts/Base.astro";
export async function getStaticPaths() {
const posts = await getCollection("blog");
return posts.map((post) => ({
params: { slug: post.slug },
props: {
post,
},
}));
}
const { post } = Astro.props;
const { title, summary, createdDate, tags } = post.data;
const { Content } = await post.render();
---
<Base>
<h1>{title}</h1>
<Content />
</Base>
```
We call the `render()` function on the `post` object, store it as `Content`, and then add that to the HTML as `<Content />`.
You should now see the blog post content when you go to `http://localhost:4321/blog/my-first-post`. Let's add some random markdown to the `my-first-post.md` file to see how the Markdown is displayed on the page (styled using the Sakura classless CSS we added). You can copy and paste random markdown using [Lorem Markdownum](https://jaspervdj.be/lorem-markdownum/).
We also want to display the tags and the created date. Let's bring those in as well from the `props` and add that to the HTML.
```jsx:src/pages/blog/[slug].astro
---
import { getCollection } from "astro:content";
import Base from "@/layouts/Base.astro";
export async function getStaticPaths() {
const posts = await getCollection("blog");
return posts.map((post) => ({
params: { slug: post.slug },
props: {
post,
},
}));
}
const { post } = Astro.props;
const { title, summary, createdDate, tags } = post.data;
const { Content } = await post.render();
---
<Base>
<h1>{title}</h1>
<div class="justify-between">
<div>
{
tags.map((t) => {
return (
<small>
<i>#{t}</i>
</small>
);
})
}
</div>
<small>{createdDate}</small>
</div>
<hr />
<Content />
</Base>
```
Let's add more posts to play around with. Go to the `blog` folder and create more files. For this example, we will create `my-second-post.md` and `my-third-post.md` with the same content as `my-first-post.md` and change only the `frontmatter` details like `title`, `summary`, `createdDate`, and `tags`.
With that, you should now be able to access the following URLs:
`http://localhost:4321/blog/my-first-post`
`http://localhost:4321/blog/my-second-post`
`http://localhost:4321/blog/my-third-post`
Great! But we now need a blog listing page where readers can find all the blog posts as a list.
### 10. Create a blog listing page
We want the listing page to be available at `/blog` which means, you guessed it, we have to add either a `blog.astro` find directly inside the `pages` folder or add an `index.astro` page inside the `pages\blog` folder. We will do the latter. We will also bring in the `Base.astro` layout (see how we are reusing the layout?).
```jsx:src\pages\blog\index.astro
---
import Base from "@/layouts/Base.astro";
---
<Base>
<h1>Posts</h1>
</Base>
```
If you navigate to `http://localhost:4321/blog`, you should see the blog listing page. Now we want to list the blog posts here.
We will use the `getCollection()` function to get the list of posts from the `blog` folder and then map over each item to display them. We will also sort the posts based on the `createdDate` we have defined in the frontmatter.
```jsx:src\pages\blog\index.astro
---
import { getCollection } from "astro:content";
import Base from "@/layouts/Base.astro";
const posts = await getCollection("blog");
const sortedPosts = posts.sort((a, b) => {
return +new Date(b.data.createdDate) - +new Date(a.data.createdDate);
});
---
<Base>
<h1>Posts</h1>
<ul>
{
sortedPosts.map((p) => {
return (
<li>
<a href={"/blog/" + p.slug}>{p.data.title}</a>
</li>
);
})
}
</ul>
</Base>
```
We can also do this for the home page and list the five most recent blog posts by editing the `src\pages\index.astro` file.
```jsx:src\pages\index.astro
---
import { getCollection } from "astro:content";
import Base from "@/layouts/Base.astro";
import { AppConfig } from "@/utils/AppConfig";
const posts = await getCollection("blog");
const sortedPosts = posts.sort((a, b) => {
return +new Date(b.data.createdDate) - +new Date(a.data.createdDate);
});
---
<Base>
<h1>{AppConfig.title}</h1>
<p>{AppConfig.description}</p>
<h3>Posts</h3>
<ul>
{
sortedPosts.slice(0, 5).map((p) => {
return (
<li>
<a href={"/blog/" + p.slug}>{p.data.title}</a>
</li>
);
})
}
</ul>
<a href="/blog">Click here</a> to view the archive.
</Base>
```
Let's add some links for easy navigation.
First, we will add a link for our blog listing page to the header. Since the links in the header come from the `pages` property in `AppConfig.ts` file, we will add a link to the blog listing page to the `pages` array.
```typescript:src\utils\AppConfig.ts
export const AppConfig = {
author: "Author Name",
title: "My personal website",
description: "This is my personal website",
image: "/images/social.png", // this will be used as the default social preview image
twitter: "@handle",
site: "https://yourwebsite.com/", // this is your website URL
pages: [{
name: "Blog",
link: "/blog"
},{
name: "About",
link: "/about"
}]
}
```
We will also add links to the previous post and the next post (if available) to the end of the blog post. To do this, we will retrieve the list of blog posts using the `getCollection()` function, sort the posts, find the index of the current post in the sorted list, and then identify the previous and next posts to display in the HTML. We do this by editing the `[slug].astro` file.
```jsx:src/pages/blog/[slug].astro
---
import { getCollection } from "astro:content";
import Base from "@/layouts/Base.astro";
export async function getStaticPaths() {
const posts = await getCollection("blog");
return posts.map((post) => ({
params: { slug: post.slug },
props: {
post,
},
}));
}
const { post } = Astro.props;
const { title, summary, createdDate, tags } = post.data;
const { Content } = await post.render();
const posts = await getCollection("blog");
const sortedPosts = posts.sort((a, b) => {
return +new Date(b.data.createdDate) - +new Date(a.data.createdDate);
});
const index = sortedPosts.findIndex((c: any) => {
return c.slug == post.slug;
});
const prev = index == 0 ? undefined : sortedPosts[index - 1];
const next =
index == sortedPosts.length - 1 ? undefined : sortedPosts[index + 1];
---
<Base>
<h1>{title}</h1>
<div class="justify-between">
<div>
{
tags.map((t) => {
return (
<small>
<i>#{t}</i>
</small>
);
})
}
</div>
<small>{createdDate}</small>
</div>
<hr />
<Content />
<hr />
<div class="justify-between">
{
prev && (
<a href={`/blog/${prev.slug}`}>
<small>← {prev.data.title}</small>
</a>
)
}
{
next && (
<a href={`/blog/${next.slug}`}>
<small>{next.data.title} →</small>
</a>
)
}
</div>
</Base>
```
We should now have navigation links at the end of the blog post. You can verify that by going to `http://localhost:4321/blog/my-second-post`.
You may have noticed that the browser tab title always says Astro. We want this to be dynamic based on the page we are on. Introducing you to the world of **Astro Integrations**.
### 11. Using our first Astro Integration to add SEO
Astro provides the ability for us to use plugins either offered directly by Astro or created by the community to build things faster through Astro Integrations. We will use the `astro-seo` integration to:
1. Fixing the title
2. Add SEO to our page (we want the search engines to find our website)
3. Add social tags (so our links will look when shared on Facebook, Twitter, etc.)
Install `astro-seo` by running the following command:
```shell
npm install astro-seo
```
We are going to import `SEO` from the `astro-seo` integration. This component expects a few props like title, description, OG info, Twitter info, etc.
Since we want to use the information corresponding to each page, we are going to define the props for our `Head.astro` component. We are also creating an interface to get type safety.
Let's create the interface first. We will create a file named `types.ts` inside the `utils` folder (`src\utils\types.ts`).
```typescript:src\utils\types.ts
export interface HeadProps {
props: {
title: string;
description: string;
image?: string | undefined;
};
}
```
Let's create a component named `Head.astro` inside the `components` folder (`src\components\Head.astro`) with the following content.
```jsx:src\components\Head.astro
---
import { SEO } from "astro-seo";
import { AppConfig } from "@/utils/AppConfig";
import { type HeadProps } from "@/utils/types";
const {
props: { title, description, image },
} = Astro.props as Props;
---
<SEO
title={title || AppConfig.title}
description={description || AppConfig.description}
openGraph={{
basic: {
title: title || AppConfig.title,
type: description || AppConfig.description,
image: AppConfig.site + (image || AppConfig.image || ""),
},
}}
twitter={{
creator: AppConfig.twitter,
}}
extend={{
link: [{ rel: "icon", href: "/favicon.svg" }],
meta: [
{
name: "twitter:image",
content: AppConfig.site + (image || AppConfig.image || ""),
},
{ name: "twitter:title", content: title || AppConfig.title },
{
name: "twitter:description",
content: description || AppConfig.description,
},
],
}}
/>
```
Now that we have the `Head.astro` component created, we want to add this to our `Base.astro` layout page so that we will have the SEO feature applied to all the pages.
We will remove the existing `<title>` tag from the `Base.astro` file and add the `<Head />` component we just created. You will immediately see an error because we have to pass the mandatory props to the `<Head>` component.
Again, instead of passing the values directly from the `<Base>` layout, we will define a prop for the layout of type `HeadProps` that we created before and have the pages that use the layout pass this information to it.
```jsx:src\layouts\Base.astro
---
import Head, { type HeadProps } from "@/components/Head.astro";
import Nav from "@/components/Nav.astro";
const {
props: { title, description, image },
} = Astro.props as HeadProps;
---
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="icon" type="image/svg+xml" href="/favicon.svg" />
<meta name="viewport" content="width=device-width" />
<meta name="generator" content={Astro.generator} />
<link rel="stylesheet" href="/css/style.css" type="text/css" />
<Head props={{ title, description, image }} />
</head>
<body>
<Nav />
<slot />
</body>
</html>
```
You will get errors in every file that uses the `Base.astro` file because we are not providing the value for the props. Let's do that for each page.
First, let's update the `src\pages\index.astro` (homepage). For this, we will page the values from the `AppConfig.ts` file.
```jsx:src\pages\index.astro
---
import { getCollection } from "astro:content";
import Base from "@/layouts/Base.astro";
import { AppConfig } from "@/utils/AppConfig";
const posts = await getCollection("blog");
const sortedPosts = posts.sort((a, b) => {
return +new Date(b.data.createdDate) - +new Date(a.data.createdDate);
});
---
<Base
props={{
title: AppConfig.title,
description: AppConfig.description,
image: AppConfig.image,
}}
>
<h1>{AppConfig.title}</h1>
<p>{AppConfig.description}</p>
<h3>Posts</h3>
<ul>
{
sortedPosts.slice(0, 5).map((p) => {
return (
<li>
<a href={"/blog/" + p.slug}>{p.data.title}</a>
</li>
);
})
}
</ul>
<a href="/blog">Click here</a> to view the archive.
</Base>
```
Next, let's fix the blog listing page `src\pages\blog\index.astro`.
```jsx:src\pages\blog\index.astro
---
import { getCollection } from "astro:content";
import Base from "@/layouts/Base.astro";
import { AppConfig } from "@/utils/AppConfig";
const posts = await getCollection("blog");
const sortedPosts = posts.sort((a, b) => {
return +new Date(b.data.createdDate) - +new Date(a.data.createdDate);
});
---
<Base
props={{
title: "My collection of essays",
description: AppConfig.description,
image: AppConfig.image,
}}
>
<h1>Posts</h1>
<ul>
{
sortedPosts.map((p) => {
return (
<li>
<a href={"/blog/" + p.slug}>{p.data.title}</a>
</li>
);
})
}
</ul>
</Base>
```
Let's fix the `About` page.
```jsx:src\pages\about.astro
---
import Base from "@/layouts/Base.astro";
import { AppConfig } from "@/utils/AppConfig";
---
<Base
props={{
title: "About | " + AppConfig.author,
description: AppConfig.description,
image: AppConfig.image,
}}
>
<h1>About</h1>
</Base>
```
Finally, we will fix the blog slug file `src\pages\blog\[slug].astro`.
```jsx:src/pages/blog/[slug].astro
---
import { getCollection } from "astro:content";
import Base from "@/layouts/Base.astro";
import { AppConfig } from "@/utils/AppConfig";
export async function getStaticPaths() {
const posts = await getCollection("blog");
return posts.map((post) => ({
params: { slug: post.slug },
props: {
post,
},
}));
}
const { post } = Astro.props;
const { title, summary, createdDate, tags } = post.data;
const { Content } = await post.render();
const posts = await getCollection("blog");
const sortedPosts = posts.sort((a, b) => {
return +new Date(b.data.createdDate) - +new Date(a.data.createdDate);
});
const index = sortedPosts.findIndex((c: any) => {
return c.slug == post.slug;
});
const prev = index == 0 ? undefined : sortedPosts[index - 1];
const next =
index == sortedPosts.length - 1 ? undefined : sortedPosts[index + 1];
---
<Base props={{ title: title, description: summary, image: AppConfig.image }}>
<h1>{title}</h1>
<div class="justify-between">
<div>
{
tags.map((t) => {
return (
<small>
<i>#{t}</i>
</small>
);
})
}
</div>
<small>{createdDate}</small>
</div>
<hr />
<Content />
<hr />
<div class="justify-between">
{
prev && (
<a href={`/blog/${prev.slug}`}>
<small>← {prev.data.title}</small>
</a>
)
}
{
next && (
<a href={`/blog/${next.slug}`}>
<small>{next.data.title} →</small>
</a>
)
}
</div>
</Base>
```
Alright, we have fixed pretty much everything. The final thing related to SEO that we need to fix is the social image. We are using the value of `image` property from the `AppConfig.ts` file everywhere but we don't have that image. You can add the image you want to display as a preview when sharing links. I usually take a screenshot of the homepage and use that. Once you choose the image, add it to `public\images\` with the name `social.png` since that's the value of `AppConfig.image`.
Alright, we are almost there setting up the blog. There are a couple more things we need for the blog to be complete.
### 12. Create an RSS feed for the blog
We have a blog but we need an RSS feed so that people can subscribe to our blog (yes, people still subscribe to blogs).
We will use another Astro integration for this called `@astro/rss`. Let's install it using the below command:
```shell
npm install @astrojs/rss
```
Let's create a file named `rss.xml.js` inside the `pages` folder (`src\pages\rss.xml.js`) with the following content.
```javascript:src\pages\rss.xml.js
import { AppConfig } from "@/utils/AppConfig";
import rss from "@astrojs/rss";
import { getCollection } from "astro:content";
export async function GET() {
const blog = await getCollection("blog");
return rss({
title: AppConfig.title,
description: AppConfig.description,
site: AppConfig.site,
items: blog.map((post) => ({
title: post.data.title,
pubDate: post.data.createdDate,
description: post.data.summary,
link: `/blog/${post.slug}/`,
})),
});
}
```
We should also add a `<link>` to our `Base.astro` file that allows browsers and other apps to auto-discover the RSS feed from our website.
Let's add the below line to the `Base.astro` file just above the `</head>` tag.
```html
<link
rel="alternate"
type="application/rss+xml"
title="{AppConfig.title}"
href="{`${AppConfig.site}rss.xml`}"
/>
```
We also have to create a sitemap and a robots.txt file so that search engines can crawl our website.
### 13. Add Sitemap and robots.txt file
We will use another Astro integration called `sitemap`. Instead of running `npm install`, we will run the below command which will both install the integration as well as auto-configure the sitemap for us.
```shell
npx astro add sitemap
```
We have to add our website URL to `astro.config.mjs` file.
```javascript:astro.config.mjs
import { defineConfig } from "astro/config";
import sitemap from "@astrojs/sitemap";
// https://astro.build/config
export default defineConfig({
site: "https://yourwebsite.com",
integrations: [sitemap()],
});
```
You can verify that the `sitemap-index.xml` file gets generated by running `npm run build` and then going to the `dist` folder created in the root of your project.
Similar to how we added a `<link>` to the RSS feed to the `Base.astro` layout file, we have to do the same for the `sitemap-index.xml` file. Let's add the below line to the `src\layouts\Base.astro` file just above the `</head>` tag.
```html
<link rel="sitemap" href="/sitemap-index.xml" />
```
Finally, let's create a `robots.txt` file inside the `public` folder (`public\robots.txt`) with the below content.
```text
User-agent: *
Allow: /
Sitemap: https://<YOUR SITE>/sitemap-index.xml
```
Congrats! If you followed the tutorial till now, you have a fully functional blog.
### 14. Preparing for deployment
We have a few dummy values that we need to change before we deploy this blog.
1. Update the `AppConfig.ts` file with the right information
2. Update the dummy URL in `astro.config.mjs` file
3. Delete the dummy Markdown files from the `content\blog` folder and add your blog posts. Don't forget to add the necessary frontmatter to each post.
4. Update the social image with the image you would like `public\images\social.png`
5. Update the `src\pages\about.astro` page with details about you
Once you've made these changes, you can deploy to one of the many services that provide free hosting for static websites.
1. [Vercel](https://vercel.com/) - [Deploy your Astro Site to Vercel | Docs](https://docs.astro.build/en/guides/deploy/vercel/)
2. [Cloudflare](https://www.cloudflare.com/) - [Astro · Cloudflare Pages docs](https://developers.cloudflare.com/pages/framework-guides/deploy-an-astro-site/)
3. [Netlify](https://www.netlify.com/) - [Astro on Netlify | Netlify Docs](https://docs.netlify.com/frameworks/astro/)
### 15. Next steps
You have a proper blog in place right now. There are a few things you can add to this to make it better.
1. Create a `src\components\footer.astro` component and add it to the `Base.astro` layout to make it part of every page
2. Add a `src\pages\now.astro` page to tell your readers about what you are doing now (following [The /now page movement | Derek Sivers](https://sive.rs/nowff))
3. Add analytics to your website (for ex: [GoatCounter – open source web analytics](https://www.goatcounter.com/))
4. Add separate collection for `notes` where you can write short notes instead of long blog posts and make it available as part of `\notes` URL similar to `\blog`
Happy coding and happy writing!

In the previous article, we learned about the introduction to the Python language, the basic syntax, the strategy framework and more. Although the content was boring, but it's a must-required skill in your trading strategy development. In this article, let's continue the path of Python with a simple strategy, step by step to help you achieve a feasible quantitative trading strategy.
## Strategy Introduction
Among many trading strategies, Donchian channel strategy should be one of the most classic breakthrough strategies. It has been famous since 1970. At that time, a company specialized in simulation testing and research on mainstream programmatic trading strategies. In all strategy tests, Donchian channel strategy was the most successful.
Later, in United States, the famous "turtle" trader training events happened, which made a great success in the history of securities trading. At that time, the "Turtles" trading method was confidential, but after more than a decade, the "Turtle Trading Law" was made public, and people discovered that the "Turtle Trading" used the improved version of the Donchian channel strategy.
The breakthrough trading strategy is adapted to the relatively smooth trend of trading varieties. The most common way for breakthrough is to use the relative positional relationship between the price support and resistance to determine the specific trading position. The Donchian channel strategy in this section is also based on this principle.
## Donchian Channel Strategy Rules
The Donchian channel is a trend-oriented indicator, and its appearance and signal are somewhat similar to the Bollinger Band indicator. However, its price channel is built according to the highest and lowest prices in a certain period. For example: the upper rail is calculated by the most recent 50 k-line's highest price; the lower rail is calculated by the most recent 50 k-line's lowest price.
as shown above: this indicator with the curve composed of three different colors, the default setting is the highest and the lowest price in the 20 cycle to display price volatility. It will show less volatility when the price is in a narrow channel, and vice versa.
If prices rise above the upper rail, the buying signal will appear; conversely, if the price fall below the lower rail, the selling signal will appear. Since the upper and lower rails which are calculated by using the lowest and highest price, so under normal circumstances, the price will not breakthrough the rails, it will move along with the rails or jumping around inside the channel.
## Donchian channel calculation method
On the FMZ Quant platform, the Donchian channel calculation is simple, you
can just access to the highest or the lowest price in the given cycle, as shown below: the 5th line is to obtain the highest price of 50 cycles, the 6th line is to obtain the lowest price of 50 cycles.
```
def main(): # program entry
exchange.SetContractType("this_week") # set the variety type by using the weekly k-line
while True: # enter the loop
records = exchange.GetRecords() # get the k line array
upper = TA.Highest(record, 50, 'high') # get the highest price of 50 cycles
lower = TA.Lowest(record, 50, 'low') # get the lowest price of 50 cycles
middle = (upper + lower) / 2 # calculate the average value of upper and lower rails
Log("upper rail: ", upper) # print the upper rail value in the log
Log("lower rail: ", lower) # print the lower rail value in the log
Log("middle rail: ", middle) # print the middle rail value in the log
```
## Strategy Logic
There are many ways to use the Donchian channel, which can be used alone or in combination with other indicators. In this section we will use it by the easiest way. That is: when prices breakthrough the upper rail, which means it breaking above the pressure line, the buying power is strong, it has formed a wave of rising energy, buying signal is generated; when the price breakthrough below the lower rail, which means it breaking below the support line, the selling signal is generated.
If the price is again dropped back to the middle rail of the channel after the opening of the long position, we believe that the strength of the buying power is weakening, or the strength of the selling power is strengthening, and the signal of opening short position is generated; the same principle apply to the opening short position
## Trading Conditions
- Long position open: If there is no position holding, and the closing price is greater than the upper rail
- Short position open: If there is no position holding, and the closing price is less than the lower rail
- Closing long position: If currently holding long position, and the closing price is less than the middle rail
- Closing short position: If currently holding short position, and the closing price is greater than the middle rail
## Strategy Code Implementation
The first step in implementing the strategy is to get the data first, because the data is a prerequisite part of the trading strategy. Think about it, what data do we need? And how to get those data?
Next is to calculate the trading logic based on these data; the final step is to trade according the logic. steps as follows:
### Step 1: Using the trading class library
You can think of the trading class library as a functional module. The advantage of using a trading class library is that it allows you to focus on writing strategy logic. For example, when we use the trading class library, in order to open or close a position, we can directly use the API interface in the trading class library; but if we don't use the trading class library, we need to obtain the market price when opening the position. Need to consider the issue of unexecuted orders and the issue of withdrawal orders, and so on.
```
def main();
wile true:
obj = ext.NewPositionManager() # using the trading class library
# followed by strategy logic and placing order part
```
The above coding part is the CTA strategy framework using the FMZ Quant tool . This is a fixed coding format, and all trading logic code will start from line 4. No other changes are required elsewhere.
### Step 2: Get all kinds of data
Think about it, what kinds of data do we need? From our strategy trading logic, we first need to obtain the current position status, and then compare the closing price with the Bollinger Band indicator upper, middle and lower rails.
- Get K line data
The first is to get the K-line data array and the current K-line closing price, with the K-line array, we can calculate the N cycle period of the highest and lowest price through the API interface. it can be written like this:
```
def main(): # main function
exchange.SetContractType("this_week") # set the variety type by using the weekly k-line
while True: # enter the loop
records = exchange.GetRecords() # get the k line array
if len(records) < 50: continue # if the number of K line is less than 50, skip this loop.
close = records[len(records) - 1].Close # get the closing price of the latest k-line
```
As shown above:
Line 4 : Get the K line array, which is a fixed format.
Line 5: Filter the length of the K line, because the parameter for calculating the Donchian channel indicator is 50, when the number of K line is less than 50, it is impossible to calculate it. So here we need to filter the number of the K line. If the number of K line is less than 50, it will skip the current loop and continue to wait for the next K line.
Line 6 : We use the code " records[ len (records) - 1] " to get the last data of the K- line array, which is the latest K-line data. This data is an object, which contains: the opening price, the highest, lowest and closing price, also the trading volume, time and other data, since it is an object, so we just use ".Close" to get the latest closing price of the K-line.
- Get position data
Position information is a very important condition in the quantitative trading strategy. When the trading conditions are established, it is necessary to judge whether to place an order by the position status and the number of positions. For example, when the conditions for opening long positions are established, if there are holding position, do not place order; if there are no position holding, place the order. This time we directly encapsulate the position information into a function, we can just call this function to use it. like this:
```
# get the position information function
def mp():
positions = exchange.GetPosition() # get the holding position array
if len(position) == 0: # if the holding position array is 0
return 0 # meaning currently has no position holding, return 0
for i in range(len(position)): # Traversing the position array
if (position[i]['Type'] == PD_LONG):
return 1 # if there are long position holding, return 1
elif (position[i]['Type'] == PD_SHORT):
return -1 # if there are short position holding, return -1
def main(): # main function
exchange.SetContractType("this_week") # set the variety type by using the weekly k-line
while True: # enter the loop
records = exchange.GetRecords() # get the k line array
if len(records) < 50: continue # if the number of K line is less than 50, skip this loop.
close = records[len(records) - 1].Close # get the closing price of the latest k-line
position = mp() # get the position information function
```
As shown above:
This is a function that gets the position information. If there are long position, the value is 1; if there are short position, the value is -1; if there are no position, the value is 0.
Line 2 : Create a function with the name "mp". This function has no parameters.
Line 3 : Get the position array, which is a fixed format.
Line 4 : Determine the length of the position array. If its length is equal to 0, it means that it has no position holding, returns 0.
Line 6 : Using the for loop, starting to traverse this array, the following logic is very simple, if it's holding long position, returns 1 ; if it's holding short position, returns -1 .
Line 18 : Call the position information function "mp".
- Acquire the highest and lowest price of the most recent 50 K-lines
In the FMZ Quant quantitative trading tool, you can directly use the " TA.Highest " and " TA.Lowest " functions without having to write your own logic calculations. And "TA.Highest" and "TA.Lowest" function returns a result of the specific values instead of an array. This is very convenient. not only that, the FMZ Quant platform has official built-in hundreds of other indicator functions.
```
# get the position information function
def mp():
positions = exchange.GetPosition() # get the holding position array
if len(position) == 0: # if the holding position array is 0
return 0 # meaning currently has no position holding, return 0
for i in range(len(position)): # Traversing the position array
if (position[i]['Type'] == PD_LONG):
return 1 # if there are long position holding, return 1
elif (position[i]['Type'] == PD_SHORT):
return -1 # if there are short position holding, return -1
def main(): # main function
exchange.SetContractType("this_week") # set the variety type by using the weekly k-line
while True: # enter the loop
records = exchange.GetRecords() # get the k line array
if len(records) < 50: continue # if the number of K line is less than 50, skip this loop.
close = records[len(records) - 1].Close # get the closing price of the latest k-line
position = mp() # get the position information function
upper = TA.Highest(record, 50, 'High') # get the highest price of 50 cycles
lower = TA.Lowest(record, 50, 'Low') # get the lowest price of 50 cycles
middle = (upper + lower) / 2 # calculate the average value of the upper and lower rail
```
As shown above:
Line 19: call "TA.Highest" function to get the highest price of 50 cycles
Line 20 : call "TA.Lowest" function to get lowest price of 50 cycles
Line 21: calculate the average value of the upper and lower rail according to highest and lowest price of 50 cycles
### Step 3: Placing Order and trade
With the above data, we can write the trading logic and placing order part now. It is also very simple, the most commonly used is the "if statement", which can be described as: if condition 1 and condition 2 are true, place the order; if condition 3 or condition 4 is are true, place the order. As shown below:
```
# get the position information function
def mp():
positions = exchange.GetPosition() # get the holding position array
if len(position) == 0: # if the holding position array is 0
return 0 # meaning currently has no position holding, return 0
for i in range(len(position)): # Traversing the position array
if (position[i]['Type'] == PD_LONG):
return 1 # if there are long position holding, return 1
elif (position[i]['Type'] == PD_SHORT):
return -1 # if there are short position holding, return -1
def main(): # main function
exchange.SetContractType("this_week") # set the variety type by using the weekly k-line
while True: # enter the loop
records = exchange.GetRecords() # get the k line array
if len(records) < 50: continue # if the number of K line is less than 50, skip this loop.
close = records[len(records) - 1].Close # get the closing price of the latest k-line
position = mp() # get the position information function
upper = TA.Highest(record, 50, 'High') # get the highest price of 50 cycles
lower = TA.Lowest(record, 50, 'Low') # get the lowest price of 50 cycles
middle = (upper + lower) / 2 # calculate the average value of the upper and lower rail
obj = ext.NewPositionManager() # using the trading class library
if position > 0 and close < middle: # If currently holding long position, and the closing price is less than the middle rail
obj.CoverAll() # close all position
if position < 0 and close > middle: # If currently holding short position, and the closing price is greater than the middle rail
obj.CoverAll() # close all position
if position == 0: # if currently holding no position
if close > upper: # if the closing price is greater than the middle rail
obj.OpenLong("this_week", 1) # open long position
elif close < lower: # if the closing price is less than the middle rail
obj.OpenShort("this_week", 1) # open short position
```
As shown above:
Line 22 : Using the trading class library, this is a fixed format
Lines 23, 24 : This is a closing long position statement that uses the "comparison operators" and "logical operators" we have learned before, meaning that if the current holding is long position, and the closing price is less than the middle rail, close all positions .
Lines 25, 26 : This is a closing short position statement that uses the "comparison operators" and "logical operators" we have learned before, meaning that if the current order is short position and the closing price is greater than the middle rail, close all positions .
Line 27 : Determine the current position status. If there are no position holding, proceed to the next step.
Lines 28, 29 : Determine whether the closing price is greater than the upper rail. If the closing price rises above the upper rail, open long position.
Lines 30, 31 : Determine whether the closing price is less than the lower rail. If the closing price falls below the lower rail, open short position.
## To sum up
Above we have learned each step of developing a complete quantitative trading strategy by using Python, including: strategy introduction, Donchian channel calculation method, strategy logic, trading conditions, strategy code implementation, etc. This section is just a simple strategy. As a method of inspiring, there are more than one way to accomplish it. You can superimpose different trading methods according to your trading system to form your own quantitative trading strategy.
## Next section notice
In the development of quantitative trading strategies, from the perspective of the speed of programming language execution, which one is the fastest? it must be the C++. Especially in the field of financial derivatives and high-frequency trading. C++ is unique in language specificity and it has advantages in numerical calculations. Compared with JavaScript and Python, its speed can be increased by several orders of magnitude. If you want to go to the field of financial derivatives or high-frequency trading in the future. This will be the course you should not miss.
## After-school exercises
1. Start from the basic and implement the strategy of this section.
2. Try to add a moving average indicator to the strategy in this section to reduce the trading frequency.

With the rise of minimally invasive pain treatments, those enduring chronic pain now have new hope.
These advanced methods not only reduce discomfort but also speed up recovery, transforming the way we approach pain management into something less intimidating and more accessible.
## The Objectives of Minimally Invasive Pain Treatments
At their essence, [minimally invasive treatments](https://www.totalpainspecialist.com/) strive to smooth out the recovery journey. They’re crafted to achieve three primary goals: significantly shorten recovery time, alleviate pain during and after the procedure, and reduce the risks of complications often linked with more invasive surgeries. These treatments do more than manage pain—they enhance the overall quality of life for patients, showing care that extends beyond the treatment table.
## 5 Types of Minimally Invasive Pain Treatments
### Radiofrequency Ablation
Imagine a method that quiets the pain signals screaming in your brain using just a touch of heat from radio waves. That’s [radiofrequency ablation](https://www.totalpainspecialist.com/service/radiofrequency-ablation/). It’s a godsend for those dealing with relentless joint or back pain.
What’s truly amazing about this treatment is its precision—it pinpoints the trouble areas without needing to make a single cut, making it incredibly non-intrusive.
### Steroid Injections
Steroid injections are often the first line of defence for rapid pain relief. They reduce inflammation right at the pain's source.
However, they’re not without their drawbacks, such as potential weight gain, mood changes, and spikes in blood sugar levels, so they’re not suitable for everyone. Think of it as a powerful tool that you need to use wisely.
### Nerve Blocks
Visualise nerve blocks as a mute button for your body’s pain alerts. This method involves injecting a numbing agent near the affected nerves, effectively blocking pain signals before they reach the brain.
It’s particularly beneficial after surgery or during sudden pain spikes, offering your body a breather to heal without the constant pain noise.
### Minimally Invasive Lumbar Decompression
For those haunted by the continuous ache of spinal stenosis, minimally invasive lumbar decompression can be a game-changer. This technique uses miniature tools to remove bone spurs and thickened ligaments that compress the nerves, all done through tiny incisions. It targets the root of the problem with minimal fuss, promoting a quicker and less painful recovery.
### Percutaneous Discectomy
Fighting a herniated disc can feel like a constant uphill struggle. Percutaneous discectomy provides a less daunting option, utilising a needle and a small incision to remove parts of the problematic disc, thus relieving nerve pressure.
This minimally invasive approach sidesteps the drama of open surgery and accelerates recovery, helping you regain your normal pace of life sooner.
## Comparing Minimally Invasive Treatments with Traditional Surgery
Choosing between minimally invasive treatments and traditional surgery involves a detailed look at the benefits and drawbacks of each. Here’s a simple breakdown:
**Complexity of the Case**: Sometimes, only traditional surgery can address complex medical issues that need direct intervention.
**Risk of Complications**: Minimally invasive methods are generally linked with fewer complications, offering a safer alternative for many who fear major surgery.
**Recovery Time**: A major advantage of minimally invasive surgery is the significantly reduced recovery time, so you’re sidelined for less time and can resume your daily activities sooner.
**Downtime**: With smaller incisions and less overall trauma, these procedures typically mean less downtime, a huge plus for anyone looking to avoid a lengthy recovery.
**Popularity and Availability**: Increasingly, these treatments are not just speciality options; they’re widely available and have a growing list of success stories, making them a popular choice for pain management without severe interventions.
## Conclusion
The landscape of pain management is rapidly changing, with minimally invasive treatments leading the revolution. They not only provide effective relief but do so in a way that respects a patient’s desire for a quick and smooth recovery.
If you're dealing with chronic pain, discussing these options with a [healthcare specialist](https://www.totalpainspecialist.com/your-visit/) might just be the transformative step you need. Remember, selecting the right treatment can profoundly improve your quality of life, turning a painful day-to-day into a more comfortable and manageable existence.

Recently, I have been wondering which coins I should invest in as an indivisual investor. And, as a DeFi developer, which product should be developed and which chain should I develop on. To resolve these questions, I have developed a family of indices called Chainsight Indices. The indices are designed to measure the market performance of crypto trading on DEX or CEX. This is available on [Chainsight](https://app.chainsight.network/). 16 indices are available now.
One of the best things about this UI is that it allows you to extract some of your own attention from the various evaluation indicators and compare them in a composite chart.
For example, the following image compares the volatility of Chainsight AI (an index of AI coins) with NVIDIA's stock price.
You can also extract indicators of interest to you in this way and save the graphs in a layout so that you can gain insight from these indicators anytime you visit [app.chainsight.network](https://app.chainsight.network/)).
I hope you find it useful.
The following is an introduction to the indices. More indicators will be added in the future.
# Introduction
## Index Objective
The Chainsight indices are a family of indices designed to measure the market performance of crypto trading on DEX or CEX. The indices are designed to be used as a benchmark for the performance of the crypto market and as a tool for investors to track the performance of their investments.
## Family of Indices
- Chainsight AI. The index mesures the performance of projects that aim to use AI and machine learning on blockchain.
- Chainsight Meme. The index measures the performance of meme coins.

It's been a while since I worked with stylesheets. I have always been a software developer focused mostly on backend functionality. Recently, however, I started using the [Bear blogging platform](https://bearblog.dev/) for [my personal website](https://yordi.me/), which allows you to customize its built-in themes.
The menu of my website is a collection of icons that link to different pages. For example, ✍️ points to a page with an overview of all my blog posts. My goal for this and other menu icons was to animate them on hover, so they scale up.
## A Simple Solution
In its basic form, the HTML of the menu looks like this:
```html
<nav>
<a href="/blog/">✍️</a>
<a href="/music/">🎼</a>
</nav>
```
Of course, I could do something simple (and probably not very professional) in CSS like this:
```css
nav a {
text-decoration: none;
}
nav a:hover {
font-size: 1.5em;
}
```
Check out this example in CodePen:
{% codepen https://codepen.io/Froodooo/pen/YzbVLMZ %}
This works, but it's far from ideal:
- There is no animated transition; a menu item immediately grows in size on hover and shrinks back on unhover.
- Surrounding menu items move around on hover.
## Working with Transitions
A better way to create good-looking animations for your menu is by using `transition`. With a transition, you can define which properties of an element will be animated. This `transition` property is placed on the main element (not on the `:hover` selector). Then, on the `:hover` selector, you can use the `transform` property to define the type of animation on hover.
In my case, the stylesheet looks like this:
```css
nav a {
display: inline-block;
text-decoration: none;
transition: transform .3s ease-in-out;
}
nav a:hover {
transform: scale(1.5);
}
```
I'll explain each part below:
- The transition animation only works for block elements, not for inline elements. So, I need to ensure that the CSS handles my `a` tags as blocks with `display: inline-block`.
- `transition: transform .3s ease-in-out` means that a `transition` is applied to the `transform` property, the animation takes `.3` seconds, and the animation is triggered both on hover and unhover.
- `transform: scale(1.5)` defines the type of transition. In this case, it scales my menu icons by a factor of `1.5`.
Check out this example in CodePen:

1,877,499 | The Future of Web Design: Expert Insights from Leading Kochi Web Design Companies | In the rapidly evolving digital landscape, staying ahead of the curve in web design is crucial for... | 0 | 2024-06-05T04:51:40 | https://dev.to/witsow_branding/the-future-of-web-design-expert-insights-from-leading-kochi-web-design-companies-5fog | In the rapidly evolving digital landscape, staying ahead of the curve in web design is crucial for businesses aiming to maintain a strong online presence. Kochi, known for its burgeoning tech scene, is home to several leading web design companies that are at the forefront of innovation. These companies are setting trends and shaping the future of web design. Let's delve into the insights from some of Kochi's top web design experts to understand what the future holds for this dynamic field.
1. Emphasis on User Experience (UX)
Leading web design companies in Kochi stress that the future of web design will be dominated by a user-centric approach. User experience (UX) will go beyond mere aesthetics to encompass functionality, ease of use, and user satisfaction. Web designers will need to deeply understand user behavior and preferences to create intuitive and engaging websites. Advanced tools and techniques, such as heat maps and user journey mapping, will become standard practices to enhance UX.
2. AI and Machine Learning Integration
Artificial intelligence (AI) and machine learning are set to revolutionize web design. Kochi's web design companies are already experimenting with AI-powered tools to create more personalized and dynamic user experiences. AI can analyze user data to offer tailored content, while machine learning algorithms can predict user behavior and adjust the website's interface in real time. This integration will make websites smarter and more adaptive to individual user needs.
3. Responsive and Adaptive Design
With the increasing variety of devices and screen sizes, responsive design is no longer optional. Leading web design companies in Kochi are focusing on creating designs that work seamlessly across all devices, from smartphones to large desktop monitors. The future will see a rise in adaptive design techniques, where websites dynamically adjust their layout and content based on the specific device and user context. This ensures a consistent and optimal user experience across all platforms.
4. Voice User Interface (VUI)
Voice search and voice-activated devices are gaining popularity, and web design is evolving to accommodate this trend. Web design companies in Kochi predict that voice user interfaces (VUIs) will become a significant aspect of web design. Designing for voice search involves optimizing website content for natural language queries and ensuring that navigation can be performed through voice commands. This shift will require designers to rethink traditional website structures and interaction models.
5. Micro-Interactions and Animations
Micro-interactions and animations are becoming essential tools for enhancing user engagement. These subtle animations and interactive elements can provide feedback, guide users, and add a layer of delight to the user experience. Kochi-based web design companies are increasingly incorporating micro-interactions to create more engaging and responsive websites. The future will see more sophisticated and meaningful use of animations to enrich user interaction.
6. Sustainable and Inclusive Design
As awareness of environmental and social issues grows, sustainable and inclusive design practices are gaining traction. Leading web design companies in Kochi are prioritizing eco-friendly design choices, such as optimizing website performance to reduce energy consumption. Additionally, there is a strong focus on accessibility, ensuring that websites are usable by people with disabilities. This includes adhering to web accessibility standards and implementing features like keyboard navigation and screen reader compatibility.
7. Augmented Reality (AR) and Virtual Reality (VR)
Augmented reality (AR) and virtual reality (VR) are set to transform the way users interact with websites. Kochi's web design experts foresee a future where AR and VR are integrated into web design to provide immersive experiences. For example, e-commerce websites could allow users to virtually try on clothes or preview furniture in their homes. These technologies will offer new possibilities for engaging users and creating memorable experiences.
8. Minimalist and Content-Focused Design
The trend towards minimalist design is expected to continue, with a strong emphasis on content. Clean, uncluttered layouts that highlight essential information will become more prevalent. Kochi's web design companies advocate for a "less is more" approach, focusing on high-quality content and efficient navigation. This minimalist trend aligns with the growing preference for fast-loading websites and a seamless user experience.
Conclusion
The future of web design is exciting and full of possibilities. Insights from leading [web design companies in Kochi](https://witsow.com/) highlight a shift towards user-centric, intelligent, and sustainable design practices. By embracing these trends, businesses can ensure that their websites remain relevant, engaging, and effective in a constantly changing digital world. Whether it's through AI integration, responsive design, or the incorporation of AR and VR, Kochi's web design experts are paving the way for a more dynamic and user-friendly web. | witsow_branding | |

1,877,490 | Why does not postgres use my index? | This is a quick note 1. Query Conditions Not Matching the Index The index is not on the... | 0 | 2024-06-05T04:40:20 | https://dev.to/jacktt/why-does-not-postgres-use-my-index-5apf | postgres, database | _This is a quick note_
## 1. Query Conditions Not Matching the Index
- The index is not on the columns being queried.
- The query does not use the leading columns of a composite index.
- The query is not written in a way that takes advantage of the index's order.
- The query uses functions or operations that prevent the use of the index (e.g., using functions like LOWER() on the column in the query).
- Data type mismatches between the column and the query can prevent index usage. Ensure that the data types match exactly.
## 2. Query Planner's Cost Estimates
- PostgreSQL's query planner estimates the cost of using the index and might decide that a sequential scan is cheaper.
- The statistics for the table are outdated or inaccurate, leading the planner to make suboptimal decisions. Running ANALYZE can help update these statistics.
## 3. Index Selectivity
The index is not selective enough. For example, if a column has many **duplicate values**, scanning the index might not save much time compared to a sequential scan.

<h2 class="wp-block-heading">Step by Step: Import Excel to MySQL</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Here's a quick overview of what we'll be doing:</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading">Step 1: Prepare Your Excel Data</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>The first step is to ensure your Excel spreadsheet is properly formatted and ready for import. Here are a few tips:</p>
<!-- /wp:paragraph -->
<!-- wp:list -->
<ul><!-- wp:list-item -->
<li>Make sure each column has a clear header that describes the data it contains</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>Remove any empty rows or columns</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>Ensure data is consistently formatted (e.g., dates are in the same format)</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>Save your Excel file in CSV format</li>
<!-- /wp:list-item --></ul>
<!-- /wp:list -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading">Step 2: Create a MySQL Database</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Next, you'll need to create a new MySQL database to house your imported Excel data. Using Five, you can easily create a MySQL database from within the platform.</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading">Step 3: Import CSV Data into MySQL</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>With your database created, you're ready to import your Excel CSV file. Five provides a simple interface for uploading your CSV and mapping the columns to your MySQL table.</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading">Step 4: Verify Successful Import</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Once the import process is complete, it's a good idea to verify that your data was successfully transferred. You can do this by running a few simple SQL queries to check that your tables are populated with the expected data.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>And that's it! By following these steps, you'll have successfully imported your Excel spreadsheet data into a MySQL database, putting you well on your way to converting your Excel-based solution into a full-fledged web application. </p>
<!-- /wp:paragraph -->

<hr class="wp-block-separator has-alpha-channel-opacity"/>
<!-- /wp:separator -->
<!-- wp:heading -->
<h2 class="wp-block-heading">Step 1: Prepare Your Excel Data</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Before you start importing your Excel data into MySQL, it's crucial to ensure that your spreadsheet is properly formatted and cleaned up. Here are some tips:</p>
<!-- /wp:paragraph -->
<!-- wp:list {"ordered":true} -->
<ol><!-- wp:list-item -->
<li>Make sure your header row (row 1) only contains descriptive names for the data stored in each column.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>Avoid repeating the same information in multiple columns. Instead, use separate columns for distinct data points.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>Ensure that each cell contains only one piece of data. Don't mix multiple data points in a single cell.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>If you have multiple values for the same item, split them across multiple columns instead of putting them in the same cell.</li>
<!-- /wp:list-item --></ol>
<!-- /wp:list -->
<!-- wp:paragraph -->
<p>For example, let’s say your spreadsheet contains information on <strong>Products, Prices, and Quantities.</strong></p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Here’s what your Excel spreadsheet should look like:</p>
<!-- /wp:paragraph -->
<!-- wp:table -->
<figure class="wp-block-table"><table><tbody><tr><td><strong>Product</strong></td><td><strong>Price</strong></td><td><strong>Quantity</strong></td></tr><tr><td>Product 1</td><td>4.99</td><td>100</td></tr><tr><td>Product 2</td><td>5.99</td><td>4</td></tr><tr><td>Product 3</td><td>100.99</td><td>58</td></tr></tbody></table></figure>
<!-- /wp:table -->
<!-- wp:paragraph -->
<p>To clean up your data, consider using these helpful Excel functions:</p>
<!-- /wp:paragraph -->
<!-- wp:list -->
<ul><!-- wp:list-item -->
<li><code>TRIM</code>: Removes leading, trailing, and extra spaces between words.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><code>CLEAN</code>: Removes all nonprintable characters from text.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><code>PROPER</code>: Converts the first character to uppercase and all other characters to lowercase.</li>
<!-- /wp:list-item --></ul>
<!-- /wp:list -->
<!-- wp:paragraph -->
<p><strong>Once you've cleaned up your data, export your excel spreadsheet into a csv file.</strong></p>

1,877,492 | Hoisting for dummies (aka me) | TL/DR: Hoisting is a useful JavaScript feature that allows you to use variables and functions before... | 0 | 2024-06-05T04:35:16 | https://dev.to/bibschan/hoisting-for-dummies-aka-me-2i6k | javascript, webdev, beginners, career |
_**TL/DR:**
Hoisting is a useful JavaScript feature that allows you to use variables and functions before they are declared. However, it's crucial to remember that only declarations are hoisted, not assignments. The keywords `let` and `const` have different hoisting behaviours, and strict mode can be used to avoid potential hoisting-related issues._
---
## A quick guide to hoisting 🏗️
Hoisting is one of those buzzwords you hear about only two times in your dev life, one is during that pesky interview and the other is when you're in school. But guess what? I never learned it (or maybe I did and forgot, sorry teacher). So, let's find out what the mystery of ✨hoisting✨ is.
The textbook definition of hoisting is **_to lift something heavy, to move from a lower position to a higher position._**
Interesting... But still doesn't click for me.
[MDN](https://developer.mozilla.org/en-US/docs/Glossary/Hoisting) defines hoisting as:
> the process whereby the interpreter appears to move the declaration of functions, variables, classes, or imports to the top of their scope, prior to execution of the code.
Ah. Now I get it.
This means that regardless of the their actual placement within the scope, you can use them as if they were declared at the beginning. If you're familiar with the black magic of `var`, that is basically hoisting at it's finest. Just add functions, classes and imports into the mix.
There is a few catches though. Only declarations are hoisted, not assignments. It also doesn't apply to arrow functions, as they are declared with the `const` keyword.
I'm a visual person, so I made some ~cool~ graphics using Figma. Check this out:
---
## Alright, I think that's it for me ┗(･ω･;)┛
Here are some key points to take home:
* **Variable and function declarations are hoisted:** Hoisting applies only to declarations, not assignments. For instance, the declaration ‘var headcount’ is hoisted, but the value assignment ‘var headcount = 10’ remains at its original location.
* **`let` and `const` behave differently:** Unlike `var`, which is hoisted to the top of its scope, `let` and `const` variables are declared in the place they are written. Attempting to access a let or const variable before its declaration will result in a reference error.
* **Hoisting in Strict Mode:** JavaScript offers a "strict mode" to prevent potential issues caused by hoisting. When running code in strict mode, `let` and `const` variables are no longer hoisted, ensuring clear and error-free code.
Hope you learned something with me today! (´◡`)

1,877,488 | Vector search in Manticore | Manticore Search since 6.3.0 supports Vector Search! Let's learn more about it – what it is, what... | 0 | 2024-06-05T04:30:58 | https://dev.to/sanikolaev/vector-search-in-manticore-f1a | Manticore Search since 6.3.0 supports **Vector Search**! Let's learn more about it – what it is, what benefits it brings, and how to use it on the example of integrating it into the [GitHub issue search demo](https://github.manticoresearch.com/).
### Full-text search and Vector search
[Full-text search](https://en.wikipedia.org/wiki/Full-text_search) is useful because it allows for efficient searching by finding exact matches of keywords. However, it mainly relies on keywords, which can sometimes be limiting. In contrast, semantic search uses vector similarity and machine learning to understand the meaning behind your search and finds documents similar to what you're looking for. This method often leads to better results and allows for searches in a more natural and relaxed style.
We are pleased to introduce this powerful feature in Manticore Search, implemented as a part of the [Columnar library](https://github.com/manticoresoftware/columnar/). Let’s explore how to get started with it.
### Get started with Vector Search and Manticore
A quick introduction to vector search: To perform **vector search**, text must be converted into vectors, which are typically ordered lists of floating-point numbers. You do the same with your query. Then, compare the vector of your query with the vectors of your documents and sort them by closeness. Read our other article about [Vector search in old and modern databases](/blog/vector-search-in-databases/).
We'll discuss how to turn text into vectors shortly, but first, let's explore how to work with vectors in **Manticore Search**.
#### Installation
Vector search functionality has been available in Manticore since version 6.3.0. Make sure **Manticore** is installed with the [Columnar library](https://github.com/manticoresoftware/columnar/). If you need help with installation, check the [documentation](https://manual.manticoresearch.com/Installation/Installation).
#### Creating a table
First, we need to create a real-time table that will contain our schema declaration. This includes a field for storing vectors, allowing us to query them using the specified syntax. Let's create a simple table. The table should have a field of type `float_vector` with configured options.
```sql
create table test ( title text, image_vector float_vector knn_type='hnsw' knn_dims='4' hnsw_similarity='l2' );
```
You can read detailed docs [here](https://manual.manticoresearch.com/Searching/KNN#Configuring-a-table-for-KNN-search).
#### Inserting data
Once the table is set up, we need to populate it with some data before we can retrieve any information from it.
```sql
insert into test values ( 1, 'yellow bag', (0.653448,0.192478,0.017971,0.339821) ), ( 2, 'white bag', (-0.148894,0.748278,0.091892,-0.095406) );
```
Manticore Search supports SQL, making it user-friendly for those familiar with SQL databases. However, if you prefer to use plain HTTP requests, that option is available too! Here's how you can perform the earlier SQL operation using HTTP:
```json
POST /insert
{
"index":"test_vec",
"id":1,
"doc": { "title" : "yellow bag", "image_vector" : [0.653448,0.192478,0.017971,0.339821] }
}
POST /insert
{
"index":"test_vec",
"id":2,
"doc": { "title" : "white bag", "image_vector" : [-0.148894,0.748278,0.091892,-0.095406] }
}
```
#### Querying the data
The final step involves querying the results using our pre-calculated request vector, similar to the document vectors prepared with AI models. We will explain this process in more detail in the next part of our article. For now, here is an example of how to query data from a table using our ready vector:
```sql
mysql> select id, knn_dist() from test where knn ( image_vector, 5, (0.286569,-0.031816,0.066684,0.032926), 2000 );
```
You'll get this:
```sql
+------+------------+
| id | knn_dist() |
+------+------------+
| 1 | 0.28146550 |
| 2 | 0.81527930 |
+------+------------+
2 rows in set (0.00 sec)
```
That is, 2 documents sorted by the closeness of their vectors to the query vector.
#### Manticore Vector search in supported clients
Manticore Search offers clients for various languages, all supporting data querying using Vector Search. For instance, here's how to perform this with the [PHP client](https://github.com/manticoresoftware/manticoresearch-php):
```php
<?php
use Manticoresearch\Client;
use Manticoresearch\Search;
use Manticoresearch\Query\KnnQuery;
// Create the Client first
$params = [
'host' => '127.0.0.1',
'port' => 9308,
];
$client = new Client($params);
// Create Search object and set index to query
$search = new Search($client);
$search->setIndex('test');
// Query now
$results = $search->knn('image_vector', [0.286569,-0.031816,0.066684,0.032926], 5);
```
Easy, right? If you want to know more about various options, you can check the [PHP client docs](https://github.com/manticoresoftware/manticoresearch-php/blob/a9aea2608eedb73e84ac0659b3ae1486a0b82761/docs/searchclass.md#knn).
### How to Convert Text to Vectors?
Let's now discuss how we can **get a vector from text**.
An "embedding" is a vector that represents text and captures its semantic meaning. Currently, Manticore Search does not automatically create embeddings. However, we are working on adding this feature and have an open [ticket on GitHub](https://github.com/manticoresoftware/manticoresearch/issues/1778) for it. Until this feature is available, you will need to prepare embeddings externally. Therefore, we need a method to convert text into a list of floats to store and later query using vector search.
You can use various solutions for converting texts to embeddings. We can recommend using [sentence transformers from Hugging Face](https://huggingface.co/sentence-transformers), which include [pre-trained models](https://www.sbert.net/) that convert text into high-dimensional vectors. These models capture the semantic similarities between texts effectively.
The process of converting text to vectors using sentence transformers includes these steps:
1. **Load the pre-trained model**: Begin by loading the desired sentence transformer model from the Hugging Face repository. These models, trained on extensive text data, can effectively grasp the semantic relationships between words and sentences.
2. **Tokenize and encode text**: Use the model to break the text into tokens (words or subwords) and convert these tokens into numerical representations.
3. **Compute vector representations**: The model calculates vector representations for the text. These vectors are usually high-dimensional (e.g., 768 dimensions) and numerically represent the semantic meaning of the text.
4. **Store vectors in the database**: Once you have the vector representations, store them in Manticore along with the corresponding text.
5. **Query**: To find texts similar to a query, convert the query text into a vector using the same model. Use Manticore Vector Search to locate the nearest vectors (and their associated texts) in the database.
## Semantic Search in the GitHub Demo
In a previous [article](https://manticoresearch.com/blog/manticoresearch-github-issue-search-demo/), we built a demo showcasing the usage of **Manticore Search** in a real-world example: [GitHub issue search](https://github.manticoresearch.com/). It worked well and already provided benefits over GitHub's native search. With the latest update to Manticore Search, which includes vector search, we thought it would be interesting to add semantic search capability to our demo. Let's explore how it was implemented.
Although most libraries that generate embeddings are written in Python, we're using PHP in our demo. To integrate vector search into our demo application, we had two options:
* An API server (which can utilize Python but might be slower)
* A PHP extension, which we have chosen to implement.
While looking into how to create text embeddings quickly and directly, we discovered a few helpful tools that allowed us to achieve our goal. Consequently, we created an [easy-to-use PHP extension](https://github.com/manticoresoftware/php-ext-model) that can generate text embeddings. This extension lets you pick any model from Sentence Transformers on HuggingFace. It is built on the [CandleML](https://github.com/huggingface/candle) framework, which is written in Rust and is a part of the well-known [HuggingFace](https://huggingface.co/) ecosystem. The PHP extension itself is also crafted in Rust using the [php-ext-rs](https://github.com/davidcole1340/ext-php-rs) library. This approach ensures the extension runs fast while still being easy to develop.
Connecting all the different parts was challenging, but as a result, we have [this extension](https://github.com/manticoresoftware/php-ext-model) that easily turns text into vectors directly within PHP code, simplifying the process significantly.
```php
<?php
use Manticore\\Ext\\Model;
// One from <https://huggingface.co/sentence-transformers>
$model = Model::create("sentence-transformers/all-MiniLM-L12-v2");
var_dump($model->predict("Hello world"));
```
The great advantage is that the model is remarkably fast at generating embeddings, and it only needs to be loaded once. All subsequent calls are executed in just a few milliseconds, providing good performance for PHP and sufficient speed for the demo project. Consequently, we decided to proceed with this approach. You can check and use our extension [on GitHub here](https://github.com/manticoresoftware/php-ext-model).
The challenging part is done; next, we need to integrate it into the [Demo project](http://github.manticoresearch.com/) with minimal code changes.
## Integration into existing code
To integrate **vector search** capability, we added a small switch to the header that allows users to change the search mode. By default, we use **keyword search** (also known as "full-text search"). It looks like this:
The changes on the backend side were not hard. We added a call to the text-to-vector conversion extension mentioned above. That's what the [code block](https://github.com/manticoresoftware/manticore-github-issue-search/blob/1c74a2ecc7aff79c353b940f898655c92c724167/app/actions/search.php#L36-L45) looks like:
```php
// Add vector search embeddings if we have a query
if ($search_query) {
if ($search !== 'keyword-search') {
$embeddings = result(TextEmbeddings::get($query));
$filters['embeddings'] = $embeddings;
}
if ($search === 'vector-search') {
$filters['vector_search_only'] = true;
}
}
```
The Hybrid Search, which combines semantic search and keyword search, can be implemented in various ways. In this case, we simply added a full-text filter to the vector search results. You can see the updated code [here](https://github.com/manticoresoftware/manticore-github-issue-search/blob/1c74a2ecc7aff79c353b940f898655c92c724167/app/src/lib/Manticore.php#L835-L859). Here is how it looks:
```php
protected static function getSearch(string $table, string $query, array $filters): Search {
$client = static::client();
$Index = $client->index($table);
$vector_search_only = $filters['vector_search_only'] ?? false;
$query = $vector_search_only ? '' : $query;
$Query = new BoolQuery();
if (isset($filters['embeddings'])) {
$Query = new KnnQuery('embeddings', $filters['embeddings'], 1000);
}
if ($query) {
$QueryString = new QueryString($query);
$Query->must($QueryString);
}
return $Index->search($Query);
}
```
As we can see, integrating semantic search into the demo was straightforward. Next, let's see what we achieve with **Vector Search**.
## Comparing what we got in our Demo with Semantic Search
Let’s take a look and compare some simple result made with default **Keyword Search versus Semantic Search** in our [Demo page](https://github.manticoresearch.com/).
For example, doing a **keyword search** for `"improve performance"` might give results like this:
That looks legitimate and fair enough. But it's looking ONLY for an exact match of the original phrase. Let's see and compare it to a **semantic search** instead:
That looks somewhat flexible, though not perfect. However, we can also ask a question like `How to improve performance of Manticore Search?` and get additional relevant results.
Here, you can see that thanks to **vector search** and the machine learning model behind it, the system can precisely understand what we're looking for and provide relevant results. However, if you attempt the same search in keyword mode, you won't get any results.
## Conclusion
We're excited about Manticore's new capabilities! Now, with vector search and help from some external tools, it's easy to set up semantic search. Semantic search is a smart way to understand queries better. Instead of just looking for exact words, it figures out the meaning behind what people ask. This means it can find more relevant answers, especially for complicated or detailed questions.
By making searches more like natural conversations, semantic search closes the gap between how we talk and how data is organized. It provides precise and useful results that fit exactly what someone is looking for, making searching with Manticore a lot better.
We are now working on bringing the auto-embeddings functionality to Manticore. This will allow for automatic conversion of text into vectors, making everything simpler and faster. Keep an eye on our progress [here on GitHub](https://github.com/manticoresoftware/manticoresearch/issues/1778). With these improvements, searching with Manticore is getting even better! | sanikolaev | |

1,877,294 | React: Design Patterns | Controlled & Uncontrolled Components | React is a powerful library for building user interfaces, and one of its core strengths lies in its... | 0 | 2024-06-05T04:00:00 | https://dev.to/andresz74/react-design-patterns-controlled-uncontrolled-components-e2c | React is a powerful library for building user interfaces, and one of its core strengths lies in its flexibility. Among the many design patterns React offers, controlled and uncontrolled components are fundamental. Understanding these patterns can significantly impact how you manage state and handle user input in your applications.
## Uncontrolled Components
Uncontrolled components are those where the component itself maintains its own internal state. The only time you interact with this state is when an event occurs, such as a form submission. For instance, consider a form where you only access the input values when the user hits the submit button. Until that event, the form's state is entirely managed by the DOM elements themselves.
Here's a simple example of an uncontrolled form:
```jsx
import React, { createRef } from 'react';
export const UncontrolledForm = () => {
const nameInput = createRef();
const ageInput = createRef();
const hairColorInput = createRef();
const handleSubmit = (e) => {
e.preventDefault();
console.log(nameInput.current.value);
console.log(ageInput.current.value);
console.log(hairColorInput.current.value);
};
return (
<form onSubmit={handleSubmit}>
<input name="name" type="text" placeholder="Name" ref={nameInput} />
<input name="age" type="number" placeholder="Age" ref={ageInput} />
<input name="hairColor" type="text" placeholder="Hair Color" ref={hairColorInput} />
<input type="submit" value="Submit" />
</form>
);
};
```
In this example, the form's state is only accessed when the form is submitted. The `createRef` function is used to create references to the input elements, which are then accessed in the `handleSubmit` function.
## Controlled Components
Controlled components, on the other hand, rely on their parent component to manage their state. The state is passed down as props, and any changes to the state are handled by callback functions provided by the parent.
Here's how you might implement a controlled form
```jsx
import React, { useState } from 'react';
export const ControlledForm = () => {
const [name, setName] = useState('');
const [age, setAge] = useState('');
const [hairColor, setHairColor] = useState('');
const handleSubmit = (e) => {
e.preventDefault();
console.log(name, age, hairColor);
};
return (
<form onSubmit={handleSubmit}>
<input
name="name"
type="text"
placeholder="Name"
value={name}
onChange={(e) => setName(e.target.value)}
/>
<input
name="age"
type="number"
placeholder="Age"
value={age}
onChange={(e) => setAge(Number(e.target.value))}
/>
<input
name="hairColor"
type="text"
placeholder="Hair Color"
value={hairColor}
onChange={(e) => setHairColor(e.target.value)}
/>
<button type="submit">Submit</button>
</form>
);
};
```
In this controlled form, the state of each input is managed by React's `useState` hook. The `value` prop of each input is tied to its corresponding state variable, and the `onChange` handler updates the state whenever the user types into the input.
## Why Prefer Controlled Components?
Controlled components are generally preferred for several reasons:
1. **Reusability**: Controlled components are more reusable because their behavior is determined by their props rather than their internal state.
2. **Testability**: They are easier to test since you can set up a component with a specific state and verify its behavior without needing to simulate user interactions.
3. **Predictability**: With controlled components, you have a single source of truth for your state, making your application more predictable and easier to debug.
## Practical Examples
### Uncontrolled Forms
Uncontrolled forms defer most of their logic to the DOM elements. Here's an example:
```jsx
import React, { createRef } from 'react';
export const UncontrolledForm = () => {
const nameInput = createRef();
const ageInput = createRef();
const hairColorInput = createRef();
const handleSubmit = (e) => {
e.preventDefault();
console.log(nameInput.current.value);
console.log(ageInput.current.value);
console.log(hairColorInput.current.value);
};
return (
<form onSubmit={handleSubmit}>
<input name="name" type="text" placeholder="Name" ref={nameInput} />
<input name="age" type="number" placeholder="Age" ref={ageInput} />
<input name="hairColor" type="text" placeholder="Hair Color" ref={hairColorInput} />
<input type="submit" value="Submit" />
</form>
);
};
```
### Controlled Forms
Controlled forms manage their state through React's `useState` hook:
```jsx
import React, { useState } from 'react';
export const ControlledForm = () => {
const [name, setName] = useState('');
const [age, setAge] = useState('');
const [hairColor, setHairColor] = useState('');
const handleSubmit = (e) => {
e.preventDefault();
console.log(name, age, hairColor);
};
return (
<form onSubmit={handleSubmit}>
<input
name="name"
type="text"
placeholder="Name"
value={name}
onChange={(e) => setName(e.target.value)}
/>
<input
name="age"
type="number"
placeholder="Age"
value={age}
onChange={(e) => setAge(Number(e.target.value))}
/>
<input
name="hairColor"
type="text"
placeholder="Hair Color"
value={hairColor}
onChange={(e) => setHairColor(e.target.value)}
/>
<button type="submit">Submit</button>
</form>
);
};
```
### Controlled Modals
Modals can also be controlled or uncontrolled. An uncontrolled modal manages its own visibility state:
```jsx
import React, { useState } from 'react';
export const UncontrolledModal = () => {
const [shouldShow, setShouldShow] = useState(false);
return (
<>
<button onClick={() => setShouldShow(true)}>Show Modal</button>
{shouldShow && (
<div className="modal">
<p>Modal Content</p>
<button onClick={() => setShouldShow(false)}>Close</button>
</div>
)}
</>
);
};
```
A controlled modal relies on its parent component to manage its visibility:
```jsx
import React from 'react';
export const ControlledModal = ({ shouldShow, onRequestClose }) => {
if (!shouldShow) return null;
return (
<div className="modal">
<p>Modal Content</p>
<button onClick={onRequestClose}>Close</button>
</div>
);
};
```
In the parent component:
```jsx
import React, { useState } from 'react';
import { ControlledModal } from './ControlledModal';
const App = () => {
const [shouldShowModal, setShouldShowModal] = useState(false);
return (
<>
<button onClick={() => setShouldShowModal(!shouldShowModal)}>
{shouldShowModal ? 'Hide Modal' : 'Show Modal'}
</button>
<ControlledModal shouldShow={shouldShowModal} onRequestClose={() => setShouldShowModal(false)} />
</>
);
};
export default App;
```
## Conclusion
Controlled and uncontrolled components each have their place in React development. While uncontrolled components can be simpler and quicker to implement for basic use cases, controlled components offer greater flexibility, reusability, and testability. Understanding when and how to use each pattern will make you a more effective React developer.

1,877,478 | SPA vs MPA: Which is better? | Hey there, fellow web developers and tech enthusiasts! Today, we're diving into the age-old debate:... | 0 | 2024-06-05T03:48:41 | https://dev.to/twinkle123/spa-vs-mpa-which-is-better-4mb7 | website, webdev, devops, opensource | Hey there, fellow web developers and tech enthusiasts! Today, we're diving into the age-old debate: SPA vs MPA. If you're scratching your head, wondering what these acronyms even mean, don't worry. We've got you covered in this complete guide.
First things first, let's break down the jargon. SPA stands for Single Page Application, while MPA refers to Multi Page Application. These are two different approaches to building websites, each with its own set of pros and cons.
## Single Page Application (SPA)
Imagine a website that feels more like a sleek, modern mobile app. That's the magic of an SPA. With this approach, everything happens on a single page. No more waiting for pages to load or dealing with clunky navigation. It's all about smoothness and speed.
Under the hood, SPAs use JavaScript to dynamically update the content on the page. This means that when you interact with the website, only the necessary data is loaded from the server, making the experience feel snappy and responsive.
One of the biggest advantages of SPAs is the seamless user experience. Since everything happens on one page, users don't have to wait for new pages to load, reducing the risk of frustration and bouncing off the site. Plus, SPAs are great for creating interactive and engaging web applications.
However, SPAs aren't without their drawbacks. For one, they can be a bit trickier to develop, especially if you're new to the world of JavaScript frameworks like React or Angular. There's also the issue of SEO, as search engines might have a harder time indexing the content of an SPA.
## Multi Page Application (MPA)
On the flip side, we have the tried-and-true Multi Page Application. This is the traditional way of building websites, where each page is loaded separately. When you click on a link, the browser navigates to a new page, and the content is loaded from the server.
MPAs are perfect for websites with a lot of static content, like blogs or e-commerce sites. They're also a solid choice if SEO is a top priority, as each page has its own unique URL, making it easier for search engines to crawl and index the content.
With MPAs, you have more flexibility in terms of organizing your content. You can create a clear hierarchy and structure, making it easier for users to navigate and find what they're looking for. Plus, since each page is loaded separately, you can have different layouts and designs for different sections of your site.
However, MPAs can feel a bit slower compared to SPAs, as users have to wait for each page to load. And if you have a lot of content, the development process can be more time-consuming, as you need to create separate pages for each section of your site.
## Factors to Consider
So, how do you choose between SPA and MPA? It really depends on your specific needs and goals. Here are a few factors to consider:
1. **User Experience:** If you want to create a smooth, app-like experience for your users, an SPA might be the way to go. But if you have a content-heavy site and want to keep things simple, an MPA could be a better fit.
2. **SEO:** If search engine optimization is a key concern for your website, an MPA might be the safer choice, as it's easier for search engines to crawl and index the content.
3. **Development Complexity: **SPAs can be more complex to develop, especially if you're not familiar with JavaScript frameworks. MPAs, on the other hand, are generally simpler to build and maintain.
4. **Performance:** SPAs can feel faster and more responsive, as they only load the necessary data. However, the initial load time might be longer compared to MPAs.
At the end of the day, the choice between SPA and MPA comes down to your specific project requirements. Consider your target audience, the type of content you're presenting, and your development team's skills and expertise.
Whichever approach you choose, remember that the goal is to create a website that's user-friendly, engaging, and delivers value to your visitors. Whether you go with an SPA or an MPA, focus on creating a great user experience and delivering high-quality content.
So, there you have it! The complete guide to SPA vs MPA. Hopefully, this has helped demystify these terms and given you a better understanding of when to use each approach.
Happy coding, and may your websites be fast, responsive, and amazing! | twinkle123 |

The world of software development is undergoing a paradigm shift. Cloud-native applications, built with microservices architectures and leveraging serverless technologies, are becoming the de facto standard. While these approaches offer incredible benefits regarding agility, scalability, and resilience, they also introduce unique security challenges. This blog delves into the intricate world of cloud-native security, equipping you with the knowledge to navigate this complex landscape.
We'll explore communication patterns for microservices, delve into the security challenges posed by distributed systems, and equip you with best practices and solutions to build a secure microservices ecosystem.
Finally, we'll explore the security considerations specific to serverless computing and wrap up with a look at some exciting future trends in cloud-native security.
### 1. Microservices Communication: The Symphony of Scalability and Security
A defining characteristic of cloud-native applications is their modular architecture built on microservices. These small, independent services collaborate to deliver functionality. Communication between them is crucial, and the chosen method significantly impacts both security and performance.
### Synchronous vs. Asynchronous Communication:
Imagine a conversation with a colleague. Synchronous communication operates similarly. A service sends a request and waits for a response before proceeding.
Pros:
Provides real-time feedback, simplifying debugging by allowing you to see the immediate impact of your request.
Easier to reason about program flow, as the caller waits for the response before continuing execution.
Cons:
Limits scalability. If one service is overloaded, the entire system can slow down as other services wait for responses.
Tight coupling between services. Changes in one service can impact how others interact, making maintenance more complex.
Asynchronous communication, on the other hand, is like leaving a voicemail - the recipient gets the message later. A service sends a message and continues processing without waiting for an immediate response.
Pros:
Highly scalable. Services don't block each other, allowing the system to handle high volumes of requests efficiently.
Enables loose coupling between services. Microservices become more independent, making them easier to develop, maintain, and update.
Cons:
Introduces potential delays. Clients might need to wait for a response, impacting user experience in some scenarios.
Requires handling potential message failures or out-of-order delivery. You need mechanisms to ensure messages are received and processed correctly.
#### Code Example (REST API - Synchronous):
```python
# Service A
def get_user_data(user_id):
response = requests.get(f"http://user-service:8080/users/{user_id}")
return response.json()
```
This code snippet demonstrates a synchronous call from Service A to the user service to retrieve user data. Service A waits for the response from the user service before continuing execution.
#### Diagram (Messaging Queue - Asynchronous):
+-------------------+ +-------------------+
| Service A | ----> | Message Queue (e.g., RabbitMQ) | ----> | Service B |
+-------------------+ +-------------------+
| Sends message | (Stores messages) | Receives message
| with user ID | | and processes it
In this scenario, Service A sends a message containing the user ID to a message queue (like RabbitMQ). Service B subscribes to this queue and receives the message when it's available. Service B can then process the user ID and retrieve the user data asynchronously.
### Messaging Protocols (AMQP, Kafka):
With asynchronous communication, messages need a reliable transport mechanism. Popular protocols include:
#### AMQP (Advanced Message Queuing Protocol):
An open-standard protocol ensuring reliable message delivery with features like acknowledgments and retries. It guarantees that messages are delivered at least once, in order.
#### Kafka:
A high-throughput messaging system known for its scalability and fault tolerance. It offers flexibility in message delivery guarantees (at-least-once, exactly-once), making it suitable for various use cases.
Choosing the right communication pattern depends on your specific requirements. Synchronous communication might be preferable for simple interactions requiring real-time feedback. However, for high-volume, loosely coupled interactions, asynchronous communication with message queues is often the preferred approach.
### API Gateway Design:
An API gateway acts as a central point of entry for clients (mobile apps, web applications) to interact with your microservices. It plays a crucial role in security by:
#### Managing communication:
The gateway routes requests to the appropriate microservice, shielding clients from the complexities of service discovery. This simplifies client development and improves maintainability as service locations can change without impacting clients.
#### Enforcing security:
The gateway can implement authentication and authorization checks to ensure only authorized users can access specific services or functionalities. This centralizes security logic, making it easier to manage and enforce security policies across your microservices.
### API Security Considerations:
Beyond the gateway's role, here are additional security considerations for APIs:
#### API Key Management:
Use strong, regularly rotated API keys to authenticate API calls. Avoid embedding API keys directly in client applications.
#### Rate Limiting: Implement rate limiting to prevent denial-of-service attacks by throttling the number of requests an API can receive from a single source.
#### Input Validation: Validate all user-provided data within the API to prevent injection attacks (e.g., SQL injection) that could compromise your backend systems.
## 2. Cloud-Native Security Challenges: Fortressing Your Distributed Landscape
The distributed nature of cloud-native applications, with multiple interconnected services, introduces unique security challenges that require careful consideration:
#### Increased Attack Surface:
Traditional applications often have a well-defined perimeter to secure. Cloud-native applications, on the other hand, have a broader attack surface due to the numerous microservices and communication channels. Each service becomes a potential entry point for malicious actors.
### Mitigating the Risk:
#### Microservice Least Privilege:
Implement the principle of least privilege for microservices. Grant each service only the permissions it needs to fulfill its specific function. This reduces the potential damage if a service is compromised.
#### Network Segmentation:
Utilize security groups or virtual network firewalls to restrict communication between microservices. This creates isolated zones within your cloud environment, limiting the lateral movement of attackers who might breach one service.
### Communication Security:
Communication between microservices needs to be secured to prevent eavesdropping or data tampering.
#### Encryption in Transit:
Encrypt communication channels using protocols like TLS (Transport Layer Security) to ensure data confidentiality and integrity.
#### Mutual Authentication:
Implement mutual authentication mechanisms to ensure both services involved in communication are legitimate. This prevents unauthorized services from masquerading as valid ones.
#### DevSecOps and Shifting Responsibilities:
Traditional security approaches often treated security as an afterthought. DevSecOps integrates security considerations throughout the development lifecycle, from code development to deployment and ongoing operations.
#### Security Automation:
Automate security testing throughout the development pipeline using tools like SAST (Static Application Security Testing) and DAST (Dynamic Application Security Testing) to identify and fix vulnerabilities early.
#### Infrastructure as Code (IaC) Security:
Define security best practices within your IaC templates (e.g., Terraform) to ensure consistent security configurations across deployments. This helps to "shift left" security by baking security into the infrastructure provisioning process.
## 3. Cloud-Native Security Solutions: Building a Secure Microservices Ecosystem
Securing cloud-native applications requires a multi-layered approach that addresses the unique challenges discussed above. Here are some key security solutions to consider:
#### Secrets Management:
Sensitive data like API keys, passwords, and database credentials should never be stored directly in code. Utilize secrets management tools that provide secure storage and access control mechanisms. These tools can rotate secrets automatically and grant access only to authorized services or users.
#### Runtime Security Monitoring:
Continuously monitor your microservices for suspicious activity. Security information and event management (SIEM) tools can aggregate logs from various sources, including microservices, network devices, and security tools. This allows you to identify anomalies that might indicate potential security incidents.
### Container Security:
Containerization is a popular approach for packaging and deploying microservices. However, container images and registries can introduce security vulnerabilities.
#### Vulnerability Scanning:
Regularly scan container images for known vulnerabilities using vulnerability scanners.
#### Content Trust:
Implement content trust mechanisms in your container registry to ensure the integrity and authenticity of container images. This helps to prevent deploying malicious container images.
`docker trust inspect <image_name>:<tag>`
This command allows you to verify the content trust information for a specific container image within a Docker registry.
### Service Discovery Security:
Service discovery mechanisms like Consul or Eureka help microservices find each other. However, these can also be exploited by attackers.
#### Secure Service Registration:
Implement access controls to restrict which services can register with the discovery service.
#### Encrypted Communication:
Utilize encryption for communication between service discovery components to prevent eavesdropping.
By implementing these solutions and best practices, you can significantly improve the security posture of your cloud-native applications.
### Identity and Access Management (IAM):
IAM plays a crucial role in securing cloud-native applications by managing access to resources.
#### Fine-grained Access Control:
Implement granular access controls that define who (users, services) can access specific resources (microservices, databases, storage) and what actions they can perform (read, write, delete). This minimizes the potential damage if an attacker gains access.
#### Least Privilege Principle:
Apply the principle of least privilege consistently. Grant users and services only the minimum permissions required to fulfill their designated tasks.
### Cloud Workload Protection Platform (CWPP):
Cloud providers offer CWPP solutions that provide comprehensive security for cloud-native workloads. These platforms can include features like:
#### Vulnerability Scanning:
Automated scanning of cloud resources for vulnerabilities in operating systems, container images, and applications.
#### Intrusion Detection and Prevention (IDS/IPS):
Monitoring network traffic for malicious activity and blocking potential attacks.
#### Threat Intelligence:
Integrating with threat intelligence feeds to stay informed about the latest threats and vulnerabilities.
#### Cloud Workload Protection Platform - AWS Security Hub
AWS Security Hub is a CWPP service that aggregates security findings from various AWS services and partner security solutions. It provides a central view of your security posture and helps prioritize remediation efforts.
## 4. Serverless Computing and Security: When the Cloud Does the Heavy Lifting
Serverless computing offers a pay-per-use model where you deploy code without managing servers. Security considerations in this environment have their own nuances:
### Shared Responsibility Model:
Cloud providers manage the underlying infrastructure security, but application owners are responsible for securing their code and data.
#### Understanding the Shared Model:
It's crucial to familiarize yourself with your cloud provider's shared responsibility model documentation to understand where the line is drawn between provider and customer responsibility.
### Function Code Security:
Serverless functions process data and execute tasks. Here's how to secure your functions:
#### Input Validation:
Validate all user-provided input to prevent injection attacks (e.g., SQL injection, NoSQL injection). Sanitize and validate data before processing it within your functions.
#### Authorization Checks:
Implement mechanisms to ensure only authorized users or services can invoke specific functions. Utilize IAM roles or other authentication mechanisms to control access.
#### Secure Coding Practices:
Follow secure coding practices to minimize vulnerabilities within your serverless functions. This includes avoiding common pitfalls like insecure direct object references (IDOR) and cross-site scripting (XSS).
### Event Source Security:
Events trigger serverless functions. Secure these events to prevent unauthorized access or manipulation:
#### Use authenticated event sources:
When possible, leverage mechanisms like IAM roles to authenticate events originating from other AWS services.
#### Validate event data:
Sanitize and validate event data to prevent malicious code injection. Don't blindly trust data received through events.
### Best Practices for Serverless Security:
#### Minimize Permissions:
Grant serverless functions only the minimum permissions they need to execute their tasks. This principle minimizes the potential damage if a function is compromised.
#### Logging and Monitoring:
Implement logging and monitoring for your serverless functions to track their execution and identify potential security incidents.
#### Regular Security Reviews:
Conduct regular security reviews of your serverless functions to identify and address potential vulnerabilities.
## 5. Expanding Your Cloud-Native Security Knowledge
#### Cloud-Native Observability:
Effective logging and monitoring are essential for troubleshooting issues and maintaining security. Utilize tools that provide centralized views of logs from all your microservices, infrastructure components, and serverless functions. These tools can help you identify suspicious activity and diagnose security incidents.
#### Cloud-Native Testing Strategies:
Security testing should be integrated throughout the development pipeline. Automate security checks to identify and fix vulnerabilities early in the development process. Tools like SAST (Static Application Security Testing) and DAST (Dynamic Application Security Testing) can be valuable additions. Consider integrating penetration testing (pentesting) to simulate real-world attacks and identify potential weaknesses in your defenses.
#### Security Champions:
Foster a culture of security within your development teams. Train developers to write secure code and identify potential security risks during development. Consider establishing security champions within your teams who can champion secure coding practices and stay updated on the latest security threats.
### The Future of Cloud-Native Security
AI-powered Threat Detection: Machine learning can analyze vast amounts of data from logs, metrics, and network traffic to identify anomalies and potential security threats in real-time. This allows you to proactively address security incidents before they cause significant damage.
#### Runtime Application Self-Protection (RASP):
These tools protect applications at runtime by detecting and mitigating attacks within the running code. RASP can help to identify and block zero-day attacks that traditional security solutions might miss.
#### Secure Service Mesh:
Service meshes provide a dedicated infrastructure layer for handling service-to-service communication. They can enforce security policies like encryption and authorization at the mesh layer, reducing the burden on individual microservices.
### Benefits of Service Mesh:
#### Centralized Security Policies:
Security policies can be defined and enforced at the mesh level, simplifying management and ensuring consistency across all microservices.
#### Traffic Management:
Service meshes can handle traffic routing, load balancing, and service discovery, taking these responsibilities away from individual microservices.
#### Observability:
Service meshes provide valuable insights into service-to-service communication, aiding in troubleshooting and security analysis.
#### Example (Service Mesh - Istio):
Istio is a popular open-source service mesh that provides a powerful layer for managing service communication in cloud-native environments. It offers features like:
### Traffic encryption (TLS):
Encrypts communication between services to ensure data confidentiality and integrity.
### Authorization policies:
Allows you to define who (services) can communicate with whom and what actions they can perform.
### Monitoring and observability:
Provides detailed insights into service communication patterns and potential security issues.
### Zero Trust Architecture:
Zero trust is a security model that assumes no entity, inside or outside the network, is inherently trustworthy. All access requests must be authenticated, authorized, and continuously monitored. This approach can be particularly beneficial for securing cloud-native applications with their distributed nature and numerous communication channels.
## Conclusion
Securing cloud-native applications requires a comprehensive and ongoing effort. By understanding the unique security challenges of this architecture, implementing the best practices and solutions outlined in this blog, and staying informed about the evolving security landscape, you can build and deploy secure, resilient cloud-native applications.

So, you want to learn the Python programming language but can’t find a concise and yet full-featured tutorial. This tutorial will attempt to teach you Python in 10 minutes. It’s probably not so much a tutorial as it is a cross between a tutorial and a cheatsheet, so it will just show you some basic concepts to start you off. Obviously, if you want to really learn a language you need to program in it for a while. I will assume that you are already familiar with programming and will, therefore, skip most of the non-language-specific stuff. The important keywords will be highlighted so you can easily spot them. Also, pay attention because, due to the terseness of this tutorial, some things will be introduced directly in code and only briefly commented on.
We will focus on Python 3, as that is the version you should use. All the examples in the book are in Python 3, and if anyone advises you to use 2, they aren’t your friend.
## Properties
Python is strongly typed (i.e. types are enforced), dynamically, implicitly typed (i.e. you don’t have to declare variables), case sensitive (i.e. var and VAR are two different variables) and object-oriented (i.e. everything is an object).
## Getting help
Help in Python is always available right in the interpreter. If you want to know how an object works, all you have to do is call "help(<object>)"! Also useful are "dir()", which shows you all the object’s methods, and "<object>.doc", which shows you its documentation string:
```
>>> help(5)
Help on int object:
(etc etc)
>>> dir(5)
['__abs__', '__add__', ...]
>>> abs.__doc__
'abs(number) -> number
Return the absolute value of the argument.
```
## Syntax
Python has no mandatory statement termination characters and blocks are specified by indentation. Indent to begin a block, dedent to end one. Statements that expect an indentation level end in a colon (:). Comments start with the pound (#) sign and are single-line, multi-line strings are used for multi-line comments. Values are assigned (in fact, objects are bound to names) with the equals sign (“=”), and equality testing is done using two equals signs (“==”). You can increment/decrement values using the += and -= operators respectively by the right-hand amount. This works on many datatypes, strings included. You can also use multiple variables on one line. For example:
```
>>> myvar = 3
>>> myvar += 2
>>> myvar
5
>>> myvar -= 1
>>> myvar
4
"""This is a multiline comment.
The following lines concatenate the two strings."""
>>> mystring = "Hello"
>>> mystring += " world."
>>> print(mystring)
Hello world.
# This swaps the variables in one line(!).
# It doesn't violate strong typing because values aren't
# actually being assigned, but new objects are bound to
# the old names.
>>> myvar, mystring = mystring, myvar
```
## Data types
The data structures available in python are lists, tuples and dictionaries. Sets are available in the sets library (but are built-in in Python 2.5 and later). Lists are like one-dimensional arrays (but you can also have lists of other lists), dictionaries are associative arrays (a.k.a. hash tables) and tuples are immutable one-dimensional arrays (Python “arrays” can be of any type, so you can mix e.g. integers, strings, etc in lists/dictionaries/tuples). The index of the first item in all array types is 0. Negative numbers count from the end towards the beginning, -1 is the last item. Variables can point to functions. The usage is as follows:
```
>>> sample = [1, ["another", "list"], ("a", "tuple")]
>>> mylist = ["List item 1", 2, 3.14]
>>> mylist[0] = "List item 1 again" # We're changing the item.
>>> mylist[-1] = 3.21 # Here, we refer to the last item.
>>> mydict = {"Key 1": "Value 1", 2: 3, "pi": 3.14}
>>> mydict["pi"] = 3.15 # This is how you change dictionary values.
>>> mytuple = (1, 2, 3)
>>> myfunction = len
>>> print(myfunction(mylist))
3
```
You can access array ranges using a colon (:). Leaving the start index empty assumes the first item, leaving the end index assumes the last item. Indexing is inclusive-exclusive, so specifying "[2:10]" will return items "[2]" (the third item, because of 0-indexing) to "[9]" (the tenth item), inclusive (8 items). Negative indexes count from the last item backwards (thus -1 is the last item) like so:
```
>>> mylist = ["List item 1", 2, 3.14]
>>> print(mylist[:])
['List item 1', 2, 3.1400000000000001]
>>> print(mylist[0:2])
['List item 1', 2]
>>> print(mylist[-3:-1])
['List item 1', 2]
>>> print(mylist[1:])
[2, 3.14]
# Adding a third parameter, "step" will have Python step in
# N item increments, rather than 1.
# E.g., this will return the first item, then go to the third and
# return that (so, items 0 and 2 in 0-indexing).
>>> print(mylist[::2])
['List item 1', 3.14]
```
## Strings
Its strings can use either single or double quotation marks, and you can have quotation marks of one kind inside a string that uses the other kind (i.e. “He said ’hello’.” is valid). Multiline strings are enclosed in triple double (or single) quotes (“”“). Python strings are always Unicode, but there is another string type that is pure bytes. Those are called bytestrings and are represented with the "b" prefix, for example "b'Hello \xce\xb1'". . To fill a string with values, you use the % (modulo) operator and a tuple. Each %s gets replaced with an item from the tuple, left to right, and you can also use dictionary substitutions, like so:
```
>>> print("Name: %s\
Number: %s\
String: %s" % (myclass.name, 3, 3 * "-"))
Name: Stavros
Number: 3
String: ---
strString = """This is
a multiline
string."""
# WARNING: Watch out for the trailing s in "%(key)s".
>>> print("This %(verb)s a %(noun)s." % {"noun": "test", "verb": "is"})
This is a test.
>>> name = "Stavros"
>>> "Hello, {}!".format(name)
Hello, Stavros!
>>> print(f"Hello, {name}!")
Hello, Stavros!
```
## Flow control statements
Flow control statements are "if", "for", and "while". There is no "switch"; instead, use if. Use for to enumerate through members of a list. To obtain a sequence of numbers you can iterate over, use "range(<number>)". These statements’ syntax is thus:
```
rangelist = list(range(10))
>>> print(rangelist)
range(0, 10)
>>> print(list(rangelist))
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
for number in rangelist:
# Check if number is one of
# the numbers in the tuple.
if number in (3, 4, 7, 9):
# "Break" terminates a for without
# executing the "else" clause.
break
else:
# "Continue" starts the next iteration
# of the loop. It's rather useless here,
# as it's the last statement of the loop.
continue
else:
# The "else" clause is optional and is
# executed only if the loop didn't "break".
pass # Do nothing
if rangelist[1] == 2:
print("The second item (lists are 0-based) is 2")
elif rangelist[1] == 3:
print("The second item (lists are 0-based) is 3")
else:
print("Dunno")
while rangelist[1] == 1:
print("We are trapped in an infinite loop!")
```
## Functions
Functions are declared with the "def" keyword. Optional arguments are set in the function declaration after the mandatory arguments by being assigned a default value. For named arguments, the name of the argument is assigned a value. Functions can return a tuple (and using tuple unpacking you can effectively return multiple values). Lambda functions are ad hoc functions that are comprised of a single statement. Parameters are passed by reference, but immutable types (tuples, ints, strings, etc) cannot be changed in the caller by the callee. This is because only the memory location of the item is passed, and binding another object to a variable discards the old one, so immutable types are replaced. For example:
```
# Same as def funcvar(x): return x + 1
funcvar = lambda x: x + 1
>>> print(funcvar(1))
2
# an_int and a_string are optional, they have default values
# if one is not passed (2 and "A default string", respectively).
def passing_example(a_list, an_int=2, a_string="A default string"):
a_list.append("A new item")
an_int = 4
return a_list, an_int, a_string
>>> my_list = [1, 2, 3]
>>> my_int = 10
>>> print(passing_example(my_list, my_int))
([1, 2, 3, 'A new item'], 4, "A default string")
>>> my_list
[1, 2, 3, 'A new item']
>>> my_int
10
```
## Classes
Python supports a limited form of multiple inheritance in classes. Private variables and methods can be declared (by convention, this is not enforced by the language) by adding a leading underscore (e.g. "_spam"). We can also bind arbitrary names to class instances. An example follows:
```
class MyClass(object):
common = 10
def __init__(self):
self.myvariable = 3
def myfunction(self, arg1, arg2):
return self.myvariable
# This is the class instantiation
>>> classinstance = MyClass()
>>> classinstance.myfunction(1, 2)
3
# This variable is shared by all instances.
>>> classinstance2 = MyClass()
>>> classinstance.common
10
>>> classinstance2.common
10
# Note how we use the class name
# instead of the instance.
>>> MyClass.common = 30
>>> classinstance.common
30
>>> classinstance2.common
30
# This will not update the variable on the class,
# instead it will bind a new object to the old
# variable name.
>>> classinstance.common = 10
>>> classinstance.common
10
>>> classinstance2.common
30
>>> MyClass.common = 50
# This has not changed, because "common" is
# now an instance variable.
>>> classinstance.common
10
>>> classinstance2.common
50
# This class inherits from MyClass. The example
# class above inherits from "object", which makes
# it what's called a "new-style class".
# Multiple inheritance is declared as:
# class OtherClass(MyClass1, MyClass2, MyClassN)
class OtherClass(MyClass):
# The "self" argument is passed automatically
# and refers to the class instance, so you can set
# instance variables as above, but from inside the class.
def __init__(self, arg1):
self.myvariable = 3
print(arg1)
>>> classinstance = OtherClass("hello")
hello
>>> classinstance.myfunction(1, 2)
3
# This class doesn't have a .test member, but
# we can add one to the instance anyway. Note
# that this will only be a member of classinstance.
>>> classinstance.test = 10
>>> classinstance.test
10
```
## Exceptions
Exceptions in Python are handled with try-except [exceptionname] blocks:
```
def some_function():
try:
# Division by zero raises an exception
10 / 0
except ZeroDivisionError:
print("Oops, invalid.")
else:
# Exception didn't occur, we're good.
pass
finally:
# This is executed after the code block is run
# and all exceptions have been handled, even
# if a new exception is raised while handling.
print("We're done with that.")
>>> some_function()
Oops, invalid.
We're done with that.
```
## Importing
External libraries are used with the "import [libname]" keyword. You can also use "from [libname] import [funcname]" for individual functions. Here is an example:
```
import random
from time import clock
randomint = random.randint(1, 100)
>>> print(randomint)
64
```
## File I/O
Python has a wide array of libraries built in. As an example, here is how serializing (converting data structures to strings using the "pickle" library) with file I/O is used:
```
import pickle
mylist = ["This", "is", 4, 13327]
# Open the file C:\\binary.dat for writing. The letter r before the
# filename string is used to prevent backslash escaping.
myfile = open(r"C:\\binary.dat", "wb")
pickle.dump(mylist, myfile)
myfile.close()
myfile = open(r"C:\\text.txt", "w")
myfile.write("This is a sample string")
myfile.close()
myfile = open(r"C:\\text.txt")
>>> print(myfile.read())
'This is a sample string'
myfile.close()
# Open the file for reading.
myfile = open(r"C:\\binary.dat", "rb")
loadedlist = pickle.load(myfile)
myfile.close()
>>> print(loadedlist)
['This', 'is', 4, 13327]
```
## Miscellaneous
- Conditions can be chained: "1 < a < 3" checks that a is both less than 3 and greater than 1.
- You can use "del" to delete variables or items in arrays.
- List comprehensions provide a powerful way to create and manipulate lists. They consist of an expression followed by a "for" clause followed by zero or more "if" or "for" clauses, like so:
```
>>> lst1 = [1, 2, 3]
>>> lst2 = [3, 4, 5]
>>> print([x * y for x in lst1 for y in lst2])
[3, 4, 5, 6, 8, 10, 9, 12, 15]
>>> print([x for x in lst1 if 4 > x > 1])
[2, 3]
# Check if a condition is true for any items.
# "any" returns true if any item in the list is true.
>>> any([i % 3 for i in [3, 3, 4, 4, 3]])
True
# This is because 4 % 3 = 1, and 1 is true, so any()
# returns True.
# Check for how many items a condition is true.
>>> sum(1 for i in [3, 3, 4, 4, 3] if i == 4)
2
>>> del lst1[0]
>>> print(lst1)
[2, 3]
>>> del lst1
```
- Global variables are declared outside of functions and can be read without any special declarations, but if you want to write to them you must declare them at the beginning of the function with the "global" keyword, otherwise Python will bind that object to a new local variable (be careful of that, it’s a small catch that can get you if you don’t know it). For example:
```
number = 5
def myfunc():
# This will print 5.
print(number)
def anotherfunc():
# This raises an exception because the variable has not
# been bound before printing. Python knows that it an
# object will be bound to it later and creates a new, local
# object instead of accessing the global one.
print(number)
number = 3
def yetanotherfunc():
global number
# This will correctly change the global.
number = 3
```
## Epilogue
This tutorial is not meant to be an exhaustive list of all (or even a subset) of Python. Python has a vast array of libraries and much much more functionality which you will have to discover through other means, such as the excellent book Dive into Python. I hope I have made your transition in Python easier. Please leave comments if you believe there is something that could be improved or added or if there is anything else you would like to see (classes, error handling, anything).

Title: How Medical X-Ray Machines Have Changed Over Time
Introduction:
Medical X-ray machines is a device that's essential in identifying and dealing with various medical problems. In the previous, x-ray machines were bulky and didn't provide top quality images, making it challenging for doctors to identify problems certain. However, in time, there have been developments that are remarkable in technology, leading to the development of more x-ray advanced. The development will be discussed by this article of medical x-ray machines, consisting of their advantages, innovation, safety, use, how to use, service, quality, and application.
Advantages of Medical X-Ray Machines:
One advantage of medical x-ray machines is they are non-invasive. This means doctors can obtain images of a patient's internal organs and tissues without making any incisions. In addition, x-ray machines are relatively inexpensive and readily available, making them a tool useful for medical professionals.
Innovation:
The innovation of medical Others Ultrasound Scanner x-ray machines has been significant in recent years. Traditionally, x-ray machines are used film to capture images. However, with the advancement of digital technology, most x-ray medical now use digital sensors to produce high-quality images. This has resulted in faster and more accurate diagnoses of medical conditions.
Safety:
One concern with medical x-ray machines are the potential for radiation exposure. However, modern x-ray machines are designed to emit lower levels of radiation, making them much safer than older models. In addition, medical professionals take precautions such as using lead aprons and shields to protect themselves and patients from radiation exposure.
Use:
Medical x-ray machines are used for a wide variety of purposes, including diagnosing fractures, identifying the location of foreign objects in the body, and detecting abnormalities in the lungs, heart, and other organs. X-ray machines are also used during surgeries to monitor the progress of the surgery and ensure there no complications.
How to Use:
A patient is positioned between the x-ray machine and a film or digital sensor to use a x-ray Ventilator Machine medical. The x-ray machine are then activated, and the radiation passes through the physical body, creating an image on the film or sensor digital. The medical interpreting professional image can then use it to diagnose and treat various medical conditions.
Service:
Like all equipment x-ray medical require regular maintenance to remain in good working order. Medical professionals should schedule maintenance ensure regular the x-ray machine properly calibrated and working correctly. In addition, medical professionals should follow proper disposal procedures for any used film or sensors radiation containing.
Quality:
The quality of medical x-ray images has significantly improved over the years. Modern x-ray machines provide high-quality images, allowing doctors to make more diagnoses accurate. In addition, the use of digital imaging has made it easier to store and share images, making it easier for medical professionals to together collaborate and work to treat patients.
Application:
X-ray devices have a impact that is considerable for medical treatment as they allow doctors to see inside a patient's body without intrusive treatments. This technology has led to a quicker, more medical diagnosis accurate of problems, which can lead to better treatment outcomes. Additionally, the use x-ray Holmium Laser Machine throughout surgeries has improved medical procedures making them safer and more efficient. | patricia_carrh_36f7f0b63b |

This error is caused by the following part:

```
`pkg_resources` is deprecated and `require()` doesn't work properly.
I worked around this problem by as follows:
1. Open `.venv\Lib\site-packages\pkg_resources\__init__.py`
2. rewrite \_\_version__ to `__version__ = "0.17.4"` (write installed altgraph's version)
This is a dirty workaround and should be fixed in the source code of the altgraph package.

ProseMirror is a toolkit for building... | 0 | 2024-06-05T03:20:04 | https://dev.to/joeskills/how-to-add-a-rich-text-editor-to-your-nextjs-project-using-tiptap-1fil | [Tiptap](https://tiptap.dev/) is an open source headless wrapper around [ProseMirror](https://prosemirror.net/). ProseMirror is a toolkit for building rich text WYSIWYG editors. The best part about Tiptap is that it's headless, which means you can customize and create your rich text editor however you want. I'll be using TailwindCSS for this tutorial.
## How to get Tiptap working
### Step 1 - Install Tiptap into your project
Tiptap is framework-agnostic, it integrates with many popular frameworks, even PHP and vanilla JavaScript.
There are three packages (`@tiptap/react`, `@tiptap/pm`, and `@tiptap/starter-kit`) you need to install that provide all the necessary extensions for you to add Tiptap to your Next.js project.
```
npm install @tiptap/react @tiptap/pm @tiptap/starter-kit
```
### Step 2 - Create a Tiptap component
To use Tiptap in your next.js project, you need to add a new Component. And add this piece of code to it.
```
'use client'
import { useEditor, EditorContent } from '@tiptap/react'
import StarterKit from '@tiptap/starter-kit'
const Tiptap = () => {
const editor = useEditor({
extensions: [
StarterKit,
],
content: '<p>Hello World! 🌎️</p>',
})
return (
<EditorContent editor={editor} />
)
}
export default Tiptap
```
Let me break it down. `Starterkit` is a collection of the most useful extensions in Tiptap for getting started. Extensions are a powerful way to extend the functionality of your Tiptap editor, for example, the [History plugin](https://tiptap.dev/docs/editor/api/extensions/history) that helps you track changes when editing your document and provides redo and undo options. `useEditor` is a hook provided by Tiptap that it initializes an editor instance. This instance provides the interface through which you can interact with the editor's functionality. `EditorContent` binds your editor instance and the DOM element where your content is rendered. The content property is optional, but it determines the initial state of your editor. That's all you need to get your rich text editor up and running with Tiptap.
## Customizing your editor
Since Tiptap comes raw, it allows you to choose how your editor looks like. By default, it doesn't come with a menu bar for editing your document, but you can add it by using the `slotBefore` prop in `EditorContent`. What the `slotBefore` prop does is that it tells `EditorContent` that there should be some content at the top of the editor. To create our menu bar, we can just use buttons. Let's create a menu bar and add a button to toggle boldness.
```
<div className="flex flex-wrap gap-2">
<button
onClick={() => editor.chain().focus().toggleBold().run()}
disabled={!editor.can().chain().focus().toggleBold().run()}
className={editor.isActive("bold") ? "is-active" : ""}
>
bold
</button>
</div>
```
That feels like a lot, doesn't it? Let me take it slowly. The commands that are passed into the `onClick` prop, and the `disabled` prop are a chain of commands. Each of them is explained below:
- `editor` should be a Tiptap instance,
- `chain()` is used to tell the editor you want to execute multiple commands,
- `focus()` sets the focus back to the editor,
- `toggleBold()` marks the selected text bold, or removes the bold mark from the text selection if it’s already applied and
- `run()` will execute the chain.
- `isActive()` checks if something is applied to the selected text already.
- `!editor.can()`: Checks if the `toggleBold` command can be executed. If it can't, the `!` operator negates the result.
I'm also using an `is-active` class to provide UI feedback when the button is toggled.
Now, the Tiptap component should look like this:
```
'use client'
import { useEditor, EditorContent } from '@tiptap/react'
import StarterKit from '@tiptap/starter-kit'
const Tiptap = () => {
const editor = useEditor({
extensions: [
StarterKit,
],
content: '<p>Hello World! 🌎️</p>',
})
return (
<EditorContent editor={editor} slotBefore={<div className="flex flex-wrap gap-2">
<button
onClick={() => editor.chain().focus().toggleBold().run()}
disabled={!editor.can().chain().focus().toggleBold().run()}
className={editor.isActive("bold") ? "is-active" : ""}
>
bold
</button>
</div>} />
)
}
export default Tiptap
```
You can add more buttons to toggle more things in your text like headings, paragraphs, redo/undo, blockquotes, bullet lists, and a lot more.
### (Optional) Use the `@tailwindcss/typography` to get the best typography styles for your editor
The `@tailwindcss/typography` plugin applies typography styles to your HTML elements that follow best practices. By default, TailwindCSS applies minimalistic styles and it may not include detailed typography styles. The content on your Tiptap editor is rendered as HTML by using this plugin you're telling your editor to inherit the typography styles provided by TailwindCSS such as margins, font styles, etc.
```
npm install --save-dev @tailwindcss/typography
```
You can use it by installing and then adding it to your list of plugins in your `tailwind.config.ts` or `tailwind.config.js` file:
```
import { defineConfig } from 'tailwindcss';
export default defineConfig({
mode: 'jit',
purge: ['./src/**/*.{js,jsx,ts,tsx}', './public/index.html'],
darkMode: false, // or 'media' or 'class'
theme: {
extend: {},
},
variants: {
extend: {},
},
plugins: [
require('@tailwindcss/typography'), // Add the typography plugin
// other plugins
],
});
```
All you have to do is to add the plugin. Your Tailwind config file might look different from this, but it's only the plugin that's necessary.
## Generating an output from your editor
There are two ways you can get your content from Tiptap. The first way is through JSON, and the second option is with HTML. Tiptap doesn't support Markdown as an output format. But it supports Markdown when you're editing your content. Here's an example in code:
```
const json = editor.getJSON()
```
And for HTML:
```
const html = editor.getHTML()
```
You can also listen for changes to store your content continuously as it changes. By adding the `onUpdate` hook provided by Tiptap that is triggered on every change, generating the data, and storing it:
```
const editor = useEditor({
extensions: [
StarterKit,
],
// triggered on every change
onUpdate: ({ editor }) => {
const json = editor.getJSON()
// send the content to an API here
},
content: '<p>Hello World! 🌎️</p>',
})
```
There's also one last option for storing your content, which is [y.js](https://yjs.dev/). You can head to [Tiptap's official docs](https://tiptap.dev/docs) to learn more about storing your content and how to customize it better.
That's it, that's all you need to get started with Tiptap in your Next.js project.

But fear not! GDevelop, a free and open-source game engine, offers a beginner-friendly solution to turn your game ideas into reality. This article will equip you with the fundamental knowledge to get started with GDevelop and embark on your game development journey.
1. Unveiling GDevelop: What it Offers
GDevelop stands out for its focus on accessibility. Here's what makes it ideal for beginners:
• No Coding Required: Unlike many game engines, GDevelop utilizes a visual event system. You create game logic by connecting events (like player jumping) with actions (making the character jump). This drag-and-drop approach eliminates the need for complex coding knowledge.
• Free and Open-Source: GDevelop is completely free to use and modify. Its open-source nature allows for a vibrant community and a wealth of online resources.
• 2D Game Development: GDevelop excels at creating 2D games. Whether you're crafting a classic platformer, a side-scroller shooter, or a puzzle game, GDevelop provides the tools you need.
• Cross-Platform Export: Once your game is complete, you can easily export it to various platforms like desktop (Windows, Mac, Linux), mobile (Android), and web browsers. This allows you to share your creation with a wider audience.
2. Getting Started with GDevelop:
The setup process is straightforward. Head over to https://gdevelop.io/ and download the latest version of GDevelop for your operating system. Installation is quick and painless.
3. The GDevelop Interface:
Upon launching GDevelop, you'll be greeted by a user-friendly interface:
• Project Manager: Here you manage your game projects, create new ones, and import game assets (sprites, music, sound effects).
• Scene Editor: This is your canvas for building the game world. You can create scenes (individual levels, menus, etc.), add game objects (sprites, characters, backgrounds), and define their properties and behaviors.
• Event Editor: This is the heart of GDevelop's visual scripting. Here, you connect events (like player pressing a key) with actions (making the character jump) using a drag-and-drop interface to define your game's logic.
• Object Properties: This panel allows you to adjust various aspects of your game objects, such as their position, size, animation, physics behavior, and more.

4. Building your First Game:
Let's create a simple game where you collect coins!
• New Project: In the Project Manager, click "New Project" and choose a name and location for your game.
• Creating a Scene: Right-click in the Project Manager and select "Scene" to create a new scene – this will be your game level.
• Adding a Player: In the Scene Editor, search for "Sprite" and drag it into the scene. This will be your player character. You can import a downloaded sprite image and assign it to the sprite.
• Defining Player Movement: Double-click the Sprite node in the Scene Editor to open its properties. Under "Behavior," add a "Platformer 2D Object Behavior." This enables basic platformer movement (jumping, walking) for your player.
• Adding Coins: Similar to the player, add another Sprite object for your coin collectible. You can import a coin sprite image and customize its behavior.
• Building the Level: Use a "TileMap" object to create a platforming environment for your player to navigate. You can design platforms, walls, and other level elements using tiles.
5. Adding Game Logic with Events:
Now comes the magic! In the Event Editor, you'll define how the player interacts with the game world.
Here's a simplified example of how you might connect collecting a coin:
1.Drag an event "On Collision" from the left panel and connect it to the "Actions" panel on the right.
2.Set the "Object 1" in the event properties to your player sprite and "Object 2" to your coin sprite.
3.Drag an action "Destroy Object" from the "Actions" panel and connect it to the previous event.
4.Set the "Object" property in the action to your coin sprite.
This simple event setup ensures that when your player collides with a coin (event), the coin gets destroyed (action).
6. Resources and the GDevelop Community:
GDevelop boasts a vibrant community and a wealth of resources to aid your learning journey. Here are some helpful resources:
• Official Documentation: GDevelop offers comprehensive documentation covering all aspects of the engine https://wiki.gdevelop.io/.

1,877,448 | What are SLI, SLO and SLA, and Why are they important in SRE? | Aspect Service Level Indicator (SLI) Service Level Objective (SLO) Service Level Agreement... | 0 | 2024-06-05T03:10:29 | https://dev.to/u2633/what-are-sli-slo-and-sla-and-why-are-they-important-in-sre-1h1o | sre | | **Aspect** | **Service Level Indicator (SLI)** | **Service Level Objective (SLO)** | **Service Level Agreement (SLA)** |
|------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| **Definition** | A metric that measures the performance of a service. Examples include latency, error rate, throughput, and availability. | A target value or range of values for a particular SLI over a specified time period. It represents the goal for the service's performance. | A formalized contract between a service provider and a customer outlining expected performance standards (often defined by SLOs) and the consequences of not meeting those standards. |
| **Purpose** | To provide a quantifiable measure of some aspect of the service's performance. | To set specific, measurable goals for service performance based on SLIs. | To establish clear expectations and responsibilities between the service provider and the customer, including penalties or compensations for not meeting the agreed performance levels. |
| **Examples** | - Latency (e.g., 95th percentile response time)<br>- Error rate (e.g., percentage of failed requests)<br>- Availability (e.g., uptime percentage)<br>- Throughput | - 95th percentile latency should be less than 100ms over the last 30 days<br>- Error rate should be less than 0.1% over the last 7 days<br>- Availability should be 99.9% over the last month | - The service will maintain 99.9% availability each month. If availability drops below this threshold, the service provider will credit the customer 10% of their monthly fee for each 0.1% drop below the threshold, up to 50%. |
| **Who Defines It** | Engineers and service owners who monitor and manage the service. | Engineers and service owners in collaboration with business stakeholders to ensure the objectives meet business needs and are achievable. | Business leaders, legal teams, and sometimes customers, often with input from engineers and service owners to ensure technical feasibility. |
| **Scope** | Specific aspects of service performance, typically focused on technical metrics. | Broader than SLIs, encompassing goals for multiple SLIs, often with business impact considerations. | Broad and formal, encompassing agreed-upon performance standards, legal obligations, and financial implications. |
| **Timeframe** | Continuous, providing real-time or near-real-time data on service performance. | Specific periods (e.g., weekly, monthly) over which the service's performance is evaluated against the objective. | Defined contract period, typically monthly or annually, with regular reviews and updates as needed. |
| **Consequences of Not Meeting** | Not meeting SLIs typically triggers alerts for engineers to investigate and resolve issues. | Not meeting SLOs may lead to internal reviews and action plans to improve service performance. | Not meeting SLAs typically results in penalties, such as service credits or refunds to the customer, and can damage the service provider's reputation and customer trust. |
| **Visibility** | Primarily internal, used by the service provider's engineering teams. | Internal, with visibility to both engineering teams and business stakeholders. | External, visible to both the service provider and the customer, often documented in legal contracts. |
| **Example Metrics** | - Average response time<br>- Number of errors<br>- System uptime<br>- Request per second | - 99.9% of requests should have response times under 200ms<br>- Error rate should not exceed 0.1% over a month<br>- 99.99% uptime | - 99.9% availability per month<br>- 99% of support requests answered within 24 hours<br>- 95% of incidents resolved within 4 hours |
### Summary
- **SLI**: Measures specific aspects of service performance.
- **SLO**: Sets target performance levels for SLIs.
- **SLA**: Formal agreement that includes SLOs and outlines the consequences of not meeting them.
Therefore, service providers can effectively manage and communicate their service performance, ensuring alignment with customer expectations and business objectives. | u2633 |

### Introduction to AWS Elastic Beanstalk
In today's fast-paced technological landscape, businesses and developers constantly seek efficient and scalable solutions for deploying and managing applications. AWS Elastic Beanstalk emerges as a powerful Platform-as-a-Service (PaaS) offering from Amazon Web Services (AWS) that simplifies the deployment process, allowing developers to focus on writing code without worrying about the underlying infrastructure.
Elastic Beanstalk provides an abstraction layer over the raw infrastructure components, such as EC2 instances, load balancers, and auto-scaling groups, enabling developers to deploy and manage applications seamlessly.
### How Elastic Beanstalk Works: A Behind-the-Scenes Look
At its core, Elastic Beanstalk operates on a simple yet powerful principle: you provide your application code, and the service handles the rest. Here's a step-by-step breakdown of the process:
1. **Choose Your Deployment Platform:** Elastic Beanstalk supports various platforms, including Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker. Select the platform best suited for your application.
2. **Package Your Application:** Prepare your application code and dependencies based on the chosen platform's requirements. This typically involves creating a ZIP file or a Docker image containing all the necessary components.
3. **Create an Elastic Beanstalk Environment:** An environment represents the runtime environment for your application. You define the environment's configuration, such as instance type, number of instances, load balancing options, and other settings.
4. **Upload and Deploy Your Application:** Upload your application package to Elastic Beanstalk, either through the AWS Management Console, the command-line interface (CLI), or integrated development environments (IDEs). Elastic Beanstalk automatically provisions the necessary resources, deploys your application, and configures the environment based on your specifications.
5. **Manage and Scale Your Application:** Once deployed, Elastic Beanstalk provides tools to monitor the health and performance of your application. You can easily scale your application up or down based on demand, configure logging and monitoring, and manage environment variables.
### Use Cases for AWS Elastic Beanstalk
Let's delve into some compelling use cases where Elastic Beanstalk shines:
**1. Web Applications and RESTful APIs:**
Imagine you're developing a dynamic web application or a robust RESTful API. Elastic Beanstalk effortlessly handles the deployment and scaling requirements, allowing you to focus on delivering exceptional user experiences. For example, consider a social media platform with fluctuating user traffic. Elastic Beanstalk automatically adjusts resources based on demand, ensuring optimal performance during peak hours and cost-effectiveness during low-traffic periods.
**2. Background Processing and Task Queues:**
Many applications require background processes to handle time-consuming tasks, such as image processing, data analysis, or sending email notifications. Elastic Beanstalk integrates seamlessly with services like AWS SQS (Simple Queue Service) and AWS SNS (Simple Notification Service) to create robust and scalable task processing systems. For instance, a financial application can use Elastic Beanstalk to process large volumes of transaction data asynchronously, improving application responsiveness and user satisfaction.
**3. Continuous Integration and Continuous Delivery (CI/CD) Pipelines:**
Elastic Beanstalk seamlessly integrates with popular CI/CD tools like AWS CodePipeline, Jenkins, and GitLab CI/CD, enabling automated deployment workflows. This streamlines the development process, allowing for faster and more frequent software releases. For example, a team developing a mobile game can leverage Elastic Beanstalk's CI/CD capabilities to automate the build, test, and deployment process, ensuring that new features and bug fixes reach users quickly and reliably.
**4. Development and Testing Environments:**
Elastic Beanstalk provides a cost-effective and efficient way to create isolated development and testing environments. Developers can quickly spin up environments that mirror production settings, facilitating thorough testing and reducing the risk of introducing bugs into production.
**5. Microservices Architecture:**
Elastic Beanstalk aligns well with the principles of microservices architecture, where applications are broken down into smaller, independently deployable services. Each microservice can be deployed and managed independently using Elastic Beanstalk, promoting scalability, fault isolation, and independent development cycles.
### Elastic Beanstalk vs. Other Cloud Providers and Services
While Elastic Beanstalk excels in simplifying application deployment and management on AWS, several alternative solutions are available, each with its strengths and weaknesses:
* **AWS EC2 (Elastic Compute Cloud):** Provides the greatest flexibility and control over the underlying infrastructure but requires more manual configuration and management.
* **Google App Engine:** Similar to Elastic Beanstalk but focuses primarily on Google Cloud Platform (GCP) and offers a different set of supported languages and frameworks.
* **Microsoft Azure App Service:** Offers comparable features to Elastic Beanstalk but is tightly integrated with the Azure ecosystem.
* **Heroku:** A popular PaaS platform known for its ease of use and developer-centric features. However, it may not offer the same level of customization and control as Elastic Beanstalk or other cloud-specific solutions.

### Architecting Advanced Solutions with Elastic Beanstalk: A Real-world Example
Let's imagine we are building a real-time image recognition and tagging service. This system needs to be highly scalable, resilient, and performant to handle a large volume of image uploads from users worldwide. Here's how we can leverage Elastic Beanstalk and other AWS services to architect this solution:
**Architecture Overview:**
1. **User Interface (UI):** A static website hosted on Amazon S3 and served through Amazon CloudFront for low latency and high availability.
2. **API Gateway:** Exposes RESTful APIs for image upload and tag retrieval. It handles authentication, throttling, and request routing.
3. **Image Upload Processing:** Users upload images through the UI, triggering an API Gateway endpoint. The image is securely stored in an Amazon S3 bucket.
4. **Asynchronous Image Processing:** An SQS queue receives notifications of new image uploads. An Elastic Beanstalk environment running a fleet of worker instances processes the queue.
5. **Image Recognition:** Worker instances utilize Amazon Rekognition, a pre-trained image recognition service, to extract objects, scenes, and faces from the uploaded images.
6. **Tag Storage and Retrieval:** Extracted tags are stored in a highly scalable and performant database like Amazon DynamoDB. Another API endpoint allows users to retrieve tags associated with their images.
**Benefits of this Architecture:**
* **Scalability and Performance:** Elastic Beanstalk automatically scales worker instances to handle fluctuations in image uploads, while S3, SQS, and DynamoDB provide scalable storage and processing capabilities.
* **Cost-Effectiveness:** Pay-as-you-go pricing for all services ensures you only pay for the resources you use.
* **Resiliency:** S3 provides durable storage for images, and Elastic Beanstalk's health checks and auto-scaling ensure application availability even if individual instances fail.
* **Agility and Innovation:** Leverage managed AI services like Rekognition to accelerate development and deliver advanced features without managing complex machine learning infrastructure.
This is just one example of how Elastic Beanstalk, combined with other AWS services, can create powerful and sophisticated applications. By leveraging the breadth and depth of the AWS ecosystem, we can architect solutions tailored to meet specific business needs while benefiting from the scalability, reliability, and cost-effectiveness of the cloud.

• Defining Player Movement: Double-click the KinematicBody2D node to open its inspector. Under "Script," attach a new GDScript or choose another scripting language you're comfortable with. Here, you'll write code to handle player movement (left/right keys, jumping) using Godot's built-in functions.
[Beginners Guide: Spot Trading for Various Cryptocurrencies](https://www.amazon.com/dp/B0CG4FC4DY)
• Adding Visuals: Download some free 2D character sprites online. In the Scene Editor, import the sprite image and add it as a child node to your KinematicBody2D. This visually represents your player.
• Building the Level: Use various nodes like "TileMap" to create platforms and obstacles for your player to navigate. You can adjust their properties and positions in the inspector.
4. Scripting and Logic:
Here's where Godot's scripting capabilities shine. Within your player's script, you can define how the player interacts with the game world using code.
Here's a simplified example of how you might implement player movement:
Code snippet
`func _physics_process(delta):
# Get user input (left/right)
var left = Input.is_action_pressed("move_left")
var right = Input.is_action_pressed("move_right")
# Apply movement based on input
if left:
move_and_slide(Vector2.LEFT)
elif right:
move_and_slide(Vector2.RIGHT)`
5. Exporting Your Game:
Once you're happy with your game's basic functionality, you can export it for different platforms. Godot supports exporting to desktop (Windows, Mac, Linux), mobile (iOS, Android), web platforms, and even consoles (with additional setup).

This code automates the process of scraping Wikipedia for a specified topic, processing the text, identifying topics using BERTopic, and generating questions based on these topics. It begins by installing necessary packages and setting up logging. The `scrape_wikipedia` function collects content from Wikipedia pages related to a given topic. The text is then cleaned, tokenized, and stopwords are removed. Using UMAP and CountVectorizer, the text is vectorized, and BERTopic is employed to identify key topics, with further fine-tuning using the Ollama model. Finally, questions are generated for each topic using a language model and saved for future use. This workflow is ideal for creating educational content, facilitating research, and enhancing study materials.

This next one is a variation of the script above, except it will generate comprehensive questions, essay questions.
This code automates the extraction and processing of text from a specified PDF, identifies topics within the text using BERTopic, and generates insightful questions based on these topics using a language model. It begins by loading necessary libraries and configuring logging for progress tracking. The text is extracted from the PDF and cleaned, tokenized, and filtered to remove stopwords. The processed text is then analyzed using UMAP for dimensionality reduction and BERTopic for topic modeling. Fine-tuning of topic representations is performed using the Ollama model. Representative documents for each topic are identified, and questions are generated using LangChain with a specified prompt template. The process is repeated in a loop for a defined duration, continuously generating and printing questions, which can be useful for educational and research purposes.

1,877,436 | Wrangling Your Keychain: A Guide to Apple Certificates for App Development | For any aspiring iOS, iPadOS, macOS, or watchOS developer, Apple's certificates and Keychain Access... | 0 | 2024-06-05T02:57:03 | https://dev.to/epakconsultant/wrangling-your-keychain-a-guide-to-apple-certificates-for-app-development-53b6 | For any aspiring iOS, iPadOS, macOS, or watchOS developer, Apple's certificates and Keychain Access can feel like a mystical realm. But fear not! Understanding these tools is crucial for signing and deploying your apps. This guide will equip you with the knowledge to confidently manage your Apple certificates and Keychain for a smooth development experience.
Certificates 101: Your App's Identity
Apple utilizes certificates as a digital signature, verifying your app's legitimacy and origin. There are two primary types for app development:
• Development Certificates: Used for testing your app on real devices during development. These have a one-year validity and allow you to install your app on devices enrolled in your Apple Developer Program account.
• Distribution Certificates: Essential for submitting your app to the App Store. These also have a one-year lifespan and enable you to generate app signing certificates used to sign the final build for distribution.

Keychain Access: Your Secure Vault
Keychain Access, a built-in macOS app (Applications > Utilities), acts as your secure storage for certificates, private keys, and passwords. These elements work together seamlessly to sign your app. Here's what you'll find inside:
• Certificates: The public keys that identify your developer identity.
• Keys: The private keys associated with your certificates, kept secret within Keychain Access. These are crucial for signing your app.
• Provisioning Profiles: Configuration files linking your certificates with specific devices or the App Store for deployment.
The Signing Ceremony: Signing Your App for Release
When your app is ready for deployment, you'll need to sign it. This process involves using your certificates and private keys to cryptographically bind your code to your Apple developer identity. Here's a simplified breakdown:
1.Create a Distribution Certificate: Enroll in the Apple Developer Program and generate a distribution certificate.
2.Generate a Signing Certificate: Use your distribution certificate to create an app signing certificate through Xcode or Apple Developer Portal. This signing certificate contains your private key.
3.Configure a Provisioning Profile: Create or download a provisioning profile that connects your app signing certificate with your development team and deployment target (App Store or specific devices).
4.Sign Your App: Within Xcode, use the generated provisioning profile to sign your app. This embeds the signing certificate and ensures Apple recognizes your app.
Keeping Your Keychain Tidy
• Certificate Expiration: Apple certificates expire annually. Renew them promptly to avoid signing issues.
• Organization: Use descriptive names for your certificates and keys to maintain clarity within Keychain Access.
• Security: Never share your private keys or provisioning profile details. These are essential for app security.
Additional Tips:
• Export your certificates: Back up your certificates as .p12 files for easy import onto other development machines.
• Automatic Signing: Enable automatic code signing within Xcode for a streamlined development workflow.
• Stay Updated: Refer to Apple's official documentation for the latest guidelines on certificates, keys, and provisioning profiles https://developer.apple.com/documentation.
By understanding these concepts and following these practices, you'll be well on your way to managing your Apple certificates and Keychain Access with confidence. Remember, a well-organized keychain is a happy developer's keychain!

In my previous blog post, I wrote about objects and classes and how they can be used to represent entities, objects, and relationships in code. As part of that post I touched on object relational mapping, the concept of using classes to map relational databases. Using these structures to store, visualize, and manipulate data is extremely powerful, but doesn't mean much either without data, or without the _right kind_ of data. When we write applications, we design them to perform any number of actions (ranging from simple to complex) on the data that they're given. If they are unable to perform those actions in the intended manner, or at all, errors and unexpected behavior can occur. Not only can this have a negative impact on how our application runs, it can also present security risks, especially in the case of user generated data. All of this begs the question, how do we make sure that the data our application receives is of the type(s) we originally intended? The answer lies in constraints and validations.
##Ports of Entry
By using constraints and validations we can check what kind(s) of data are coming into our application, prevent unwanted data from being used, and return useful messages to the user to help them understand where they went wrong. There are multiple points at which one might validate the data in an application. The first is in the front end where a user is inputting data. The second is server side, in the the classes used to instantiate objects. The third is at the database level, when the data is being committed. The first two use validations, while the third uses constraints.
##Client Side Validation
When dealing with user input, two of the major concerns are human error and security. Client side validation isn't particularly good at addressing the latter of the two, but is fantastic for the former. It allows us to check that whatever the user inputs in a form is what our application is looking for, and if it's not, giving immediate feedback and preventing that data from making it to other parts of the application. While it's entirely possible to build validator functions of one's own, there are libraries such as Formik that can help us streamline the process.
##Server Side Validation
As mentioned before, client side validation isn't the most useful from a security perspective. After all, someone who's intentionally trying to feed unwanted data to an application may very well bypass the front end altogether, rendering form validation completely useless. We can implement validations in our ORMs to protect against such attacks, as well as ensure that the data coming through our ORM is what our application is designed to handle. Once again, while we can write our own validator functions, frameworks such as Flask provide validation features to streamline the process.
##Database Constraints
A database constraint is functionally distinct from an ORM validation. While a validation is only checked when data is being added or updated through the ORM, constraints are checked any and every time changes or updates are made to the database. In the case of SQLalchemy there are certain constrains such as "nullable" and "unique" which are set with boolean values on columns, and others called "check constraints". As their names suggest, nullable ensures that a value is required for that column, and unique makes sure there are no repeated values in a column. On the other hand, check constraints allow us to create our own conditions, either for a specific column or for the entire table, to be checked when data is added or changed. It's worth noting that not all databases (such as mySQL) support check constraints. Additionally, there can be limitations such as with later versions of SQLalchemy where check constraints cannot be added to an existing table.
##Conclusion
Validations and constraints are essential tools in order to keep our applications secure and running smoothly. Guarding against user error, bad actors, and data inconsistencies are all important parts of development. As such, there are many different tools and techniques at our disposal to streamline the process and make things easier on ourselves as developers both when writing and servicing our (and others') code. Depending on an application's intended use, these checks can be stacked on one another to create a system of redundancies to ensure that we're getting the kind(s) of data we desire, and nothing else. | gasparericmartin | |

Diving into the world of programming has been interesting so far, and my first week was packed with tons of things I did not know and hands-on experiences. Here’s a glimpse of what I’ve learned so far:
🌐 Building a Responsive Website: I created a responsive website using HTML, showcasing the city I live in. I haven't used HTML since MySpace! lol
🤔 Who Owns the Internet? I was today years old to know that no single entity, including the government, owns the internet. It's a global network of networks, governed by protocols and standards.
🔌 Network Components & Connections: I learned the basics of network infrastructure, understanding end devices, intermediate devices, and network media. This foundational knowledge is key for me to grasp how data travels across the internet.
📶 The true definition of "Bandwidth": I finally understand what bandwidth really means – it's not about a person's capacity lol, but the rate at which data is transmitted over a network connection.
💻 Bits and Bytes: Did you know the word "computer" has 64 bits? Eight bits make a byte, so 64 bits equal 8 bytes. Simple, but yet a fundamental concept in computing that I now know :)
🚀 Supercomputers Are Real: Yes, they do exist! The US has the most supercomputers in the world with 161, including the world's fastest supercomputer, Frontier.
I am excited for the weeks ahead and all the new knowledge and skills to come! Tune in next week for more learnings.
If you are just starting your coding journey comment below the cool and interesting things you are learning!

1,877,434 | Best Age for Children and Teenagers to Start Using Social Media | Introduction The question of when children and teenagers should start using social media... | 0 | 2024-06-05T02:46:33 | https://dev.to/synthscript/best-age-for-children-and-teenagers-to-start-using-social-media-3m07 | children, socialmedia | **Introduction**
The question of when children and teenagers should start using social media platforms is an equivocal topic. Some argue in favour of early exposure aiding digital literacy and social skills; I firmly advocate placing a later age limit for accessing social media platforms. In my opinion, the right age should be at least 16 years old. This belief is based on worries about mental health, privacy dangers, and the importance of maturity required to handle the challenges of online interactions.
A new report from [PrivacyHQ.com](https://privacyhq.com/news/social-media-for-kids/), reveals that 63 percent of parents allow their pre-teens to use YouTube, 54 percent permit the use of Instagram, and 49 percent let their children use TikTok. Moreover, 64 percent of parents reported their child's desire to become an influencer on Instagram or a YouTube content creator in the future, in comparison 81 percent of those parents surveyed said they would support that decision. As exciting and straightforward as it seems, we should ask whether kids truly grasp what it takes to build a following or realize that not everyone will become influential in the long run.
Here we will discuss the impact of social media, highlighting its potential to shape children’s personal development and societal norms.
Firstly, social media can mould attitudes, minds, mental health, values, and behaviours, having both negative and positive consequences. This is a result of the lack of universal ratings for content on social media platforms, unlike TV, movies, or video games.
Although educational videos and content are available online, we cannot rule out that there is still content inappropriate for children under the age of 13, and this puts children and teens at risk of cyberbullying, discrimination, hate speech, and posts promoting self-harm.
Moreover, exposure to social media before the age of 16 can put children and teenagers at risk of predators. This can result in oversharing, social isolation, and social media over-dependence.
In addition, younger users may not fully comprehend the long-term consequences of sharing personal information online. Waiting until they clock 16 allows for more mature decision-making and a better understanding of privacy settings and online safety measures.
In counterargument, we may agree to the expansion of learning opportunities and digital literacy for older children facilitated by social media homework. This can be cultivated through other means like supervised internet use, educational programs, and guidance from parents and educators.
Additionally, children below the age of 16 can only be introduced to social media platforms if certain policies are put in place. First, the provision of a safe environment or better compliance policy with age restrictions to certain features and websites. Removal of inappropriate content and items, commissioning, publishing, and implementing research on how to make platforms safer, friendlier, and healthier for children of all ages, are good options that should be implemented.
Also, parents must have open and honest conversations with their kids about the healthy use of social media. They must emphasize how social media isn’t real– and can be misleading and highlight the importance of using social media to engage in genuine conversations with friends.
**Conclusion**
In conclusion, setting the appropriate age for the use of social media to 16 or above prioritizes the well-being and safety of children and young adults which allows for more mature decision-making and reduces psychological risks.

1,877,432 | CSS Naming Convention yang Perlu Diketahui dan Kenapa Perlu Digunakan | Kalau teman-teman pengen bikin website yang keren dan gampang diatur, teman-teman kudu ngerti yang... | 0 | 2024-06-05T02:42:15 | https://dev.to/yogameleniawan/css-naming-convention-yang-perlu-diketahui-dan-kenapa-perlu-digunakan-1l7j | css |
Kalau teman-teman pengen bikin website yang keren dan gampang diatur, teman-teman kudu ngerti yang namanya konvensi penamaan CSS. Ini kayak aturan main buat ngasih nama class dan ID di CSS biar kode teman-teman gampang dibaca dan dipelihara. Ada beberapa gaya penamaan yang sering dipake: BEM, OOCSS, SMACSS, dan Atomic CSS. Nih gue jelasin satu-satu dengan bahasa yang asik.
**1. BEM (Block, Element, Modifier)**
BEM ini pendekatan dari Rusia yang bikin kode teman-teman lebih terstruktur.
- Block: Ini kayak komponen utama, misal tombol atau menu.
- Element: Bagian dari block, kayak item di dalam menu.
- Modifier: Variasi dari block atau element, kayak tombol yang warnanya beda.
```html
<div class="menu">
<ul class="menu__list">
<li class="menu__item menu__item--active">Home</li>
<li class="menu__item">About</li>
<li class="menu__item">Contact</li>
</ul>
</div>
```
```css
.menu { ... }
.menu__list { ... }
.menu__item { ... }
.menu__item--active { ... }
```
Kenapa Pake Ini:
- **Jelas**: Nama-nama class-nya gampang dipahami.
- **Gampang Diatur**: Kode lebih terorganisir, jadi kalo mau ubah sesuatu, gak bikin pusing.
- **Bisa Dipake Ulang**: Teman-teman bisa pake komponen yang sama di tempat lain tanpa masalah.
**2. OOCSS (Object-Oriented CSS)**
OOCSS ini kayak OOP di pemrograman, fokusnya ke komponen yang bisa dipake berulang.
- Memisahkan Struktur dan style: Struktur di satu class, style di class lain.
- Komponen Reusable: Bikin komponen generik yang bisa dipake di mana aja.
Contoh:
```html
<div class="box box--small color-primary">
<p class="text">This is a small box with primary color.</p>
</div>
```
```css
.box { ... }
.box--small { width: 100px; height: 100px; }
.color-primary { background-color: blue; }
.text { ... }
```
Kenapa Pake Ini:
- **Modular**: Teman-teman bisa bikin komponen yang terpisah dan bisa dipake ulang.
- **Gampang Diatur**: Mudah buat maintain, karena struktur dan style terpisah.
**3. SMACSS (Scalable and Modular Architecture for CSS)**
SMACSS ini cara buat ngatur CSS yang fleksibel dengan kategorikan aturan jadi lima: Base, Layout, Module, State, dan Theme.
- Base: Style dasar buat elemen HTML.
- Layout: Style buat tata letak utama.
- Module: Komponen yang bisa dipake ulang.
- State: Style buat status khusus dari modul.
- Theme: Variasi tema buat modul atau layout.
Contoh:
```html
<div class="header">
<h1 class="header__title">Website Title</h1>
<nav class="header__nav">
<ul class="nav__list">
<li class="nav__item">Home</li>
<li class="nav__item nav__item--active">About</li>
</ul>
</nav>
</div>
```
```css
.header { ... }
.header__title { ... }
.header__nav { ... }
.nav__list { ... }
.nav__item { ... }
.nav__item--active { ... }
```
Kenapa Pake Ini:
- **Skalabilitas**: Kode tetap rapi walau proyek gede.
- **Modular**: Bikin komponen yang bisa dipake ulang dengan aturan jelas.
**4. Atomic CSS**
Atomic CSS ini setiap class cuma punya satu properti CSS, kayak utility-first CSS.
Contoh:
```html
<div class="d-flex justify-center align-items-center p-2">
<p class="text-center font-bold">Hello, world!</p>
</div>
```
```css
.d-flex { display: flex; }
.justify-center { justify-content: center; }
.align-items-center { align-items: center; }
.p-2 { padding: 0.5rem; }
.text-center { text-align: center; }
.font-bold { font-weight: bold; }
```
Kenapa Pake Ini:
- **Konsisten**: Utility classes bikin gaya yang sama di seluruh proyek.
- **Cepat**: Teman-teman bisa cepat apply gaya tanpa nulis CSS baru.
**Kesimpulan**
Pake _CSS Naming Conventions_ itu penting biar kode teman-teman rapi dan gampang diatur. Mau pake BEM, OOCSS, SMACSS, atau Atomic CSS, tergantung kebutuhan proyek teman-teman. Yang jelas, dengan penamaan yang konsisten, teman-teman bakal lebih mudah maintain dan ngembangin website teman-teman. Jadi, mulai sekarang coba deh ikutin salah satu konvensi ini, pasti bakal kerasa bedanya! Sampai bertemu di artikel yang lain!! | yogameleniawan |
1,846,216 | How to Deploy MERN Stack over Kubernetes | Hello Everyone, Welcome to another blog! In this blog post, we will talk about how easily you can... | 0 | 2024-06-05T02:33:02 | https://devtron.ai/blog/how-to-deploy-mern-stack-over-kubernetes/ | mern, kubernetes, mongodb, devtron | Hello Everyone, Welcome to another blog! In this blog post, we will talk about how easily you can deploy your MERN stack over Kubernetes with just a few clicks using Devtron.
Yes, you read it right! You don't have to write a number of yamls or pipelines to deploy your entire stack over Kubernetes.
Let's go ahead and see how we can achieve this.
## MERN Stack
MERN Stack is a combination of different technologies summing up the entire stack. It consists of the following technologies:
- MongoDB - Use for database
- Express(.js) - Used node.js web framework
- React(.js) - Used for developing client-side JavaScript framework
- Node(.js) - Used for developing the premier JavaScript web server
## Why Kubernetes?
Before we start with the hands-on journey, Why do we need to deploy MERN Stack over Kubernetes? To answer this question, let's take a step back.
Traditionally, for deploying containerized applications/stacks, docker was heavily used. We can containerize each of the technologies say - MongoDB in a container, react in another container, and node-express in a different container and link them all with certain port numbers to work together. Or we can use docker-compose to deploy the entire stack.
But when you talk about auto-scaling and high availability, these tools aren't enough to meet the requirements. This is where Kubernetes comes into the picture.
It is an open-source container orchestration platform for automating deployments, scaling, and management of containers. To know more about why you need to migrate to Kubernetes, please click here
## Getting Started
Now that we know the need for migration, let's get our hands dirty. In this blog, we will show how to deploy a simple CRUD application that is divided into three parts -
1. - Database (MongoDB)
2. - Backend (Node & Express)
3. - Frontend (React Code)
For the database, we will use a community helm chart. All the deployments will be carried out by using Devtron.
> [Note: If you haven't installed Devtron, feel free to check out the well-managed documentation and join the devtron discord community for any help]
## Deploying MongoDB
To deploy MongoDB, we will use `bitnami/mongodb(13.1.2)` chart that is easily accessible in Devtron's Chart Store as you can see in the image below.
Once you get the chart, click on it. It will open the configuration window where you have to provide details for the App Name, Project, and Environment in which you want to deploy. Additionally, it also shows all the chart configurations where you can make any changes if required. For this, please make the following changes:
```
auth:
rootUser: root
rootPassword: "abhinav123"
```
Once you click the Deploy Chart button, your database is up and running. You will be able to check out all the resources it has deployed, including the status of the application, the chart version, and many more as shown below.
Now that our chart is deployed, let's move ahead and deploy the backend of our application.
> [Note: To deploy any helm chart using Devtron, please have a look at this blog].
## Deploy Backend
To deploy the backend (Express & Node), we have to create a `custom app` from the Devtron dashboard. Devtron is capable enough to deploy any kind of application irrespective of the language or stack chosen for the project. Let's move ahead and onboard the backend app.
Step 1: Click on the `Create` dropdown, and select `Custom App`, it will open a window and ask for details as shown below. Provide the necessary details and click `Create App`
Step 2: After creating an app, you will be redirected to the `App Configuration` tab where you need to provide the `Git Repository` (source code URL), `Docker Build Config` (container repository name), configure `Base Deployment Template` (k8s configs), ConfigMaps & Secrets if any. For a detailed understanding of App Configuration, feel free to check out the documentation.
For this tutorial, we will configure the ingress and port number in the Deployment Template. For ingress, make sure that the ingress controller has been deployed. Feel free to check out this blog to configure the ingress controller using Devtron.
```
ContainerPort:
- envoyPort: 8799
port: 8082
```
```
ingress:
annotations: {}
className: nginx
enabled: true
hosts:
- host: backend.devtron.info
pathType: ImplementationSpecific
paths:
- /
```
After making these necessary changes, leave all the configurations as default. That's the beauty of the deployment template provided by Devtron. You don't have to write big YAMLs for k8s configuration. Everything, right from the pod specs, hpa, keda-autoscaling, service, ingress, etc. is pre-configured. You just have to tweak some values as per the requirements and deploy it.
Step-3: Now let's move ahead and create a CI/CD pipeline using Workflow Editor. Just click `Build Pipeline` → `Continuous Integration` and provide the necessary details to create your CI Pipeline.
After the CI Pipeline is created, Click the + icon to create a CD Pipeline corresponding to that CI. Configure the details, and click `Create Pipeline`.
Woohoo! We are done with creating the pipeline for our backend application. Now that we don't have any ConfigMaps or Secrets for this application, let's move to the Build & Deploy tab and trigger the CI Build.
Step-4: Click `Select Material`, select the commit against which you want to build an image, then click `Start Build`. It will start building your image. You can see runtime logs, commit details for the particular build, security results (if enabled), and artifacts.
Step-5: After building the image, click on `Select Image` your deployment pipeline, and deploy the image that you have built. You can also check the commit for which image was built on the deployment dashboard itself.
Now for more details of the deployment, navigate to App Details tab and you can see all the information about your application. The environment in which it is deployed, k8s resources it has like pods, services, etc, manifests, logs, and much more can be found on the Devtron dashboard itself just like we had in the MongoDB chart when it was deployed.
## Deploy Frontend
Now that our backend is deployed, let's deploy the frontend application (React). To deploy it, we need to follow the same steps that we followed in the case of the backend. But instead of configuring all the configs again, we can use the clone feature of Devtron that would do all the configs for us. We would just have to replace the git repo of the source code, minor changes in the deployment template, and then we are good to build & deploy the application.
Step 1: Create a `custom app`, check the `clone` button, and select the `mern-backend` (backend application name)
Step 2: After the app is created, it will take you to App Configuration tab wherein you have to replace the git URL with the frontend URL. Then move to the Deployment template, change the port number, and ingress hostname. In our case, we have made the following changes.
```
ContainerPort:
- envoyPort: 8799
port: 80
servicePort: 80
ingress:
annotations: {}
className: "nginx"
enabled: true
hosts:
- host: frontend.devtron.info
pathType: ImplementationSpecific
paths:
- /
```
After making these changes, build the image as we did for the backend application and deploy it. Once the application is up and running, we will be able to access the application at the host we have provided in ingress configurations.
Hurray! The application is up and running. It is also connected with the backend and the backend is connected with the database as you can see in the above image we have added a New Book and it is successfully added.
You can try out the application too at frontend.devtron.info/
The entire MERN Stack deployment can be seen on [Devtron's preview dashboard](https://preview.devtron.ai/dashboard/login/sso?continue=/). Feel free to sign up for the dashboard using GitHub and explore Devtron's features.
If you like Devtron, do give us a [start on](https://github.com/devtron-labs/devtron?ref=devtron.ai) Git Hub and join the [Discord community](https://discord.devtron.ai/?ref=devtron.ai) for all the latest updates. | devtron_inc |

It can be used to check for network attacks or to troubleshoot networking issues. Meanwhile, MMDB is a database format created by MaxMind for IP lookup. Inside WireShark, there is an option to retrieve IP geolocation data using the MMDB IP database. In this article, we’ll explore how to use [IP2Convert Geolocation File Format Converter](https://github.com/ip2location/ip2convert) to read data from IP2Location LITE DB9 IPv6 CSV file and generate the corresponding GeoLite2 City MMDB file.
## So why the need for conversion?
Wireshark natively supports the MMDB format from MaxMind for geolocation services. However, if you want to use an alternative geolocation service like [IP2Location](https://www.ip2location.com#devto), there is no external plugin available for integration. The only method would be via the MMDB data file. Therefore, this tutorial provides a workaround to convert the IP2Location CSV file into MMDB format so it can be used by WireShark with the geolocation function turned on.
Let’s get started with our guide for the conversion.
## Installing WireShark
First and foremost, you will need to have WireShark installed on your system. In our case, we are doing the conversion using our Windows 11 machine, hence the steps will be more Windows-specific. Do note however that WireShark can also be used in Linux or macOS. You can just change the steps for the platform you are using. We’ll download WireShark from [https://www.wireshark.org/download.html](https://www.wireshark.org/download.html) and install it in our Windows 11.
## Download the IP2Convert tool
Now, we’ll download the free IP2Convert tool from GitHub at [https://github.com/ip2location/ip2convert/releases/latest](https://github.com/ip2location/ip2convert/releases/latest) where we will get the windows_amd64 version. Remember to download the version specific to your platform. Extract the .exe file into a folder. In our case, we’ll use C:\TestWireShark\ as our folder to store the IP2Convert executable.
## Download the IP2Location LITE DB9 IPv6 CSV
Download the [IP2Location LITE DB9 IPv6 CSV file](https://lite.ip2location.com/database/db9-ip-country-region-city-latitude-longitude-zipcode#devto) which you can download for free after signing up for an account. Extract the file IPV6-COUNTRY-REGION-CITY-LATITUDE-LONGITUDE-ZIPCODE.CSV from the downloaded zipped file and save it to the same folder as above.
Your TestWireShark folder should now look like the below:
In our case, the latest version of the IP2Convert at the point of writing is 1.2.1 so that’s what you’ll see above. To make it easier to type, let's rename the .exe to ip2convert.exe so that we don’t have to type so long in the next steps.
## Let’s generate the MMDB file
Open a Command Prompt window and navigate to the TestWireShark folder.
```
cd C:\TestWireShark
```
Then run the below command to perform the CSV to MMDB conversion.
```
ip2convert csv2mmdb -t city -i IPV6-COUNTRY-REGION-CITY-LATITUDE-LONGITUDE-ZIPCODE.CSV -o DB9IPV6.mmdb
```
The -t parameter is to specify that we want to generate the GeoLite2 City MMDB while the -i and -o are used to specify the input CSV file and output MMDB file.
## Launch WireShark and configure the IP geolocation function
Launch WireShark then click on “Edit” in the menu bar. Click on “Preferences”.
You should now see the Preferences window. Click on “Name Resolution” on the left hand side. There are a couple of settings we need to set. Make sure the “Enable IP geolocation” checkbox is checked. Next, click on “Edit” next to the “MaxMind database directories”.
Add the folder that we’ve created above into the list. Then click on OK.
## Select the network adapter to capture traffic
You can double click on the network adapter that you want to capture the network traffic from. In our example, it’s “Ethernet 2”.
## Start the network traffic capture
Click the start capture button and you should start seeing a bunch of traffic coming and going from the adapter you’ve selected.
## Take a look at the inline geolocation data
Once you’ve captured enough traffic, we can stop the capture and delve into the IP geolocation data. Let’s click on one of the lines of traffic and expand the “Internet Protocol Version 6” section so we can see the IP geolocation for the traffic source & destination.
We can see that the source of the traffic is Sydney, Australia while the destination is Kuala Lumpur, Malaysia.
## See the geolocation for all endpoints
That’s just 1 line of traffic. Now, let’s go to the Endpoints window to view all of the geolocation traffic. In the menu, click on “Statistics” and then click on “Endpoints”.
Inside, you’ll see the below. Just click on the IPv4 or IPv6 tab and you can view all of the IP geolocation data. Pretty good way to quickly scan for potential issues.
## View the geolocations on a map
Looking at the list of locations is useful for troubleshooting and security purposes. But, sometimes you want to have a nice visual representation of the locations. That’s what the map feature is for. With the locations plotted on a map, you can easily discern if the traffic is coming from specific regions. Click on “Map” then click on “Open in browser”.
All of the geolocation is now shown in the map below. Pretty interesting and useful.
## Bonus Tip: Filtering the traffic by geolocation
Let’s close the Endpoints window and take another look at the main capture window. The data, while useful, certainly could use some filtering to make more sense. Say that I want to see traffic to Dublin. We can easily right-click on the city name and click “Prepare as Filter” then click “Selected”.
You’ll now see the filter created near the top of the window. Press the arrow at the end of the green bar and you’ll see the filtering being applied.
Now, you’ll only see traffic that matches the filter which is Dublin, Ireland as the destination.
## Conclusion
Hope you’ve found our little guide for using IP2Convert to create MMDB files and using them in WireShark to be useful in your day-to-day operations. With IP2Convert, you now have the flexibility to deploy IP geolocation data from IP2Location and use them wherever MMDB is supported. We’ve shown you how to use the generated MMDB in WireShark but you could potentially use the MMDB files in other applications that utilizes MMDB files for geolocation.

Image annotation is the process of adding labels or descriptions to images to provide context for computer vision models. This task involves tagging an image with information that helps a machine understand its content. Annotation is crucial in applications such as self-driving cars, medical image analysis, and satellite imagery analysis.
Annotated images are used to train computer vision models for tasks like object detection, image recognition, and image classification. By providing labels for objects within images, the model learns to identify those objects in new, unseen images.
## Types of Image Annotation
### Image Classification
In image classification, the goal is to categorize the entire image based on its content. Annotators label each image with a single category or a few relevant categories to support this task.
### Image Segmentation
Image segmentation aims to understand the image at the pixel level, identifying different objects and their boundaries. Annotators assign a label to each pixel in the image, grouping similar pixels together to support semantic segmentation. In instance segmentation, each individual object is distinguished.
### Object Detection
Object detection focuses on identifying and locating individual objects within an image. Annotators draw a box around each object and assign a label describing it. These labeled images act as ground truth data. The more precise the annotations, the more accurate the models become at distinguishing objects, segmenting images, and classifying image content.
## Introducing Annotate-Lab
Let's explore Annotate-Lab, an open-source image annotation tool designed to streamline the image annotation process. This user-friendly tool boasts a React-based interface for smooth labeling and a Flask-powered backend for data persistence and image generation.
### Installation and Setup
To install Annotate-Lab, you can clone the repository or download the project from GitHub: [Annotate-Lab GitHub Repository](https://github.com/sumn2u/annotate-lab). You can then run the client and server separately as mentioned in the documentation or use Docker Compose.
### Configuration
After starting the application, the configuration screen appears. Here, you can provide information such as labels, selection tools, and images, along with other configuration options. Below are the screenshots of the configuration screens.
### Annotation Interface
Once configured, the annotation screen appears. At the top, users will find details about the uploaded image, along with a download button on the right side, enabling them to download the annotated image, its settings, and the masked image. The "prev" and "next" buttons navigate through the uploaded images, while the clone button replicates the repository. To preserve their current work, users can use the save button. The exit button allows users to exit the application.
### Tools and Features
The left sidebar contains a set of tools available for annotation, sourced from the initial configuration. Default tools include "Select," "Drag/Pan," and "Zoom In/Out".
The right sidebar is divided into four sections: files, labels, regions, and history. The files section lists the uploaded images and allows users to navigate and save current stage changes. The labels section contains a list of labels, enabling users to select their desired label to apply it to the annotated region. The regions section lists annotated regions, where users can delete, lock, or hide selected regions. The history section shows action histories and offers a revert functionality to undo changes.
Between the left and right sidebars, there's a workspace section where the actual annotation takes place. Below is a sample of an annotated image along with its mask and settings.
```json
{
"orange.png": {
"configuration": [
{
"image-name": "orange.png",
"regions": [

}
}
```
### Demo Video
An example of orange annotation is demonstrated in the video below.
[](https://www.youtube.com/watch?v=iUI6MKWqCeg)
### YOLO Format
YOLO format is also supported by A.Lab. Below is an example of annotated ripe and unripe tomatoes. In this example, `0` represents ripe tomatoes and `1` represents unripe ones.
The label of the above image are as follows:
```
0 0.213673 0.474717 0.310212 0.498856
0 0.554777 0.540507 0.306350 0.433638
1 0.378432 0.681239 0.223970 0.268879
```
Applying the generated labels we get following results.
### Conclusion
By providing a streamlined, user-friendly interface, Annotate-Lab simplifies the process of image annotation, making it accessible to a wider range of users and enhancing the accuracy and efficiency of computer vision model training.

In the previous article, we introduced the fundamental knowledge that when using JavaScript to write a program, including the basic grammar and materials. In this article, we will use it with some common strategy modules and technical indicators to achieve a viable intraday quantitative trading strategy.
## Strategy introduction
The Bollinger Band is one of the most commonly used technical indicators, invented by John Bollinger in the 1980s. In theory, prices always fluctuate around a certain range of values. The Bollinger Band is based on this theoretical basis and introduces the concept of “price channel”.
The calculation method is to use the statistical principle, first calculate the "standard deviation" of the price for a period of time, and then add or subtract 2 times the standard deviation of the moving average to find the "trusted interval" of the price. The basic type is a strip channel consisting of three rail lines (middle rail, upper rail, lower rail). The middle rail is the average price, and the upper rail and the lower rail represent the pressure line and the support line of the price, respectively. As shown below:
Due to the concept of standard deviation, the width of the Bollinger Band is dynamically adjusted based on recent price fluctuations. When the fluctuations are small, the Bollinger Bands will be narrower; otherwise the fluctuations will be larger and the Bollinger Bands will be wider. When the BOLL channel is changing from narrow to wide, the price gradually returns to the mean. When the BOLL channel is changing from wide to narrow, it means that the market price starts to change. If the price up cross the upper-rail, it means that the buying power is enhanced. If the price goes down cross the lower-rail, it indicates that the selling power is enhanced.
## Bollinger Band Indicator Calculation Method
Among all the technical indicators, the Bollinger Band calculation method is one of the most complicated, which introduces the concept of standard deviation in statistics, involving the middle trajectory ( MB ), the upper trajectory ( UP ) and the lower trajectory ( DN ) calculation. Its calculation method is as follows:
- Middle rail = simple moving average of N time period
- Upper rail = middle rail + standard deviation of the K × N time period
- Lower rail = middle rail − standard deviation of the K × N time period
```
function main( ) { // program entry
while (true) { // enter the loop
exchange.SetContactType('this_week'); // set contact type
var records = exchange.GetRecods(); // get the k line array
var boll = TA.B0LL(records, 50); // get the 50-cycle BOLL indicator array
var top = boll[0]; // get the upper-rail BOLL indicator array
var ma = boll[l]; // get the middle-rail BOLL indicator array
var bottom = boll[2]; // get the lower-rail BOLL indicator array
Log(top); // print the upper-rail BOLL indicator array to the log
Log(ma); // print the middle-rail BOLL indicator array to the log
Log(bottom);// print the lower-rail BOLL indicator array to the log
}
}
```
## Strategy logic
The Bollinger Bands are used in a variety of ways and can be used alone or in combination with other indicators. In this section of the tutorial we will use it the easiest way, which is : When the price breaks through the upper rail, open long position; when the price breaks through the lower rail, open short position.
If the price is again returned to the middle-rail of the Bollinger Band after opening the long position, we believe that the strength of the buying power is weakening, or the strength of the selling power is strengthening, therefore, this is where the closing position signal comes in. the same logic for short position.
## Trading conditions
- Long position open: If there is no position, and the closing price is greater than the upper rail.
- Short position: If there is no position, and the closing price is lower than the lower rail.
- Close Long position: If holding long position, and the closing price is less than the middle rail,
- Close Short position: If holding short position, and the closing price is greater than the middle rail,
## Strategy code implementation
To achieve the strategy, first we need to consider what data do we need? through which API to get? Then how to calculate trading logic? Finally, which way to place the order? let's implement it step by step:
### Step 1: Use the CTA Strategy Framework
The so-called CTA Strategy framework is a set of standard frameworks that the FMZ Quant officially designed. By using this framework, you can ignore the trivial programming problem and focus directly on the logic of programming. For example, if you don't use this framework, you will need to consider shifting the order price, order type, withdrawing orders and so on.
```
function main() {
$.CTA("this_week", function(st) {
// write your strategy here
})
}
```
The above is the CTA strategy framework using the FMZ Quant tool. It is a fixed code format, and all trading logic code is starting from line 3. In addition to the need to modify the variety code in use, no other changes are required elsewhere.
Note that the above trading variety code is "this_week" meaning it represents using the weekly k-line, trading data using the weekly data.
### Step 2: Get all kinds of data
Think about it, what kinds of data do we need? From our strategy trading logic, we first need to obtain the current position status, and then compare the closing price with the Bollinger Band indicator upper, middle and lower rails.
- Get K line data
The first is to get the K-line data array and the previous K-line closing price, with the K-line array, we can calculate the Bollinger Band indicator. it can be written like this:
```
function main() {
$.CTA("this_week", function(st) {
var r = st.records; // get the k line data
if (r.length < 20) return; // filter the length of k line data
var close = r[r.length - 2].Close; // get the previous k line closing price
})
}
```
As shown above:
Line 4 : Get the K line array, which is a fixed format.
Line 5 : Filter the length of the K line, because the parameter for calculating the Bollinger Band indicator is 20, when the K line is less than 20, it is impossible to calculate the Bollinger Band indicator. So here we need to filter the length of the K line. If the K line is less than 20 , it will return directly and continue to wait for the next K line.
Line 6 : From the obtained K-line array, first obtain the object of the previous K-line, and then obtain the closing price from this object. Obtaining the penultimate element in this array, which is the length of this array minus 2(r[r.length - 2]).
The K-line array elements are all objects, the object contains the opening, highest, lowest and closing price; also the trading volume and time.
For example, to get the closing price, just add " . " follow by the attribute name (r[r.length - 2].Close).
- Get K line time data
Because this is an intraday strategy, we need to close all position before some certain time(most crypto trading exchanges usually open 24/7), so we must judge whether the current K line is close to that certain time when we what to stop trading or take a break. If it is near that closing time K line, close all position. If it is not, continue the strategy. The code is written like this:
```
function main() {
$.CTA("this_week", function(st) {
var r = st.records; // get the k line data
if (r.length < 20) return; // filter the length of k line data
var close = r[r.length - 2].Close; // get the previous k line closing price
var time = new Date(r[r.length - 1].Time); // according the current k-line timestamp, create a time object
var isClose = time.getHours() == 14 && time.getMinutes() == 45; // judging whether the current k-line is 14:45. this is just a example, you can specify any time you want during the 24 hours
})
}
```
As shown above:
Line 8: get the K line timestamp attribute objects and then create a time object(new Date (timestamp)).
Line 9: Calculate the hours and minutes according to the time object, and determine if the time of the current K line is 14:45 .
- Get position data
Position information is a very important condition in the quantitative trading strategy. When the trading conditions are established, it is necessary to judge whether to place an order by the position status and the number of positions. For example, when the conditions for opening long positions are established, if there are holding position, do not place order; if there are no position holding, place the order. like this:
```
function main() {
$.CTA("this_week", function(st) {
var r = st.records; // get the k line data
if (r.length < 20) return; // filter the length of k line data
var close = r[r.length - 2].Close; // get the previous k line closing price
var time = new Date(r[r.length - 1].Time); // according the current k-line timestamp, create a time object
var isClose = time.getHours() == 14 && time.getMinutes() == 45; // judging whether the current k-line is 14:45. this is just a example, you can specify any time you want during the 24 hours
var mp = st.position.amount; // get the holding position information
})
}
```
As shown above:
Line 11: Get the current position status. If there are long position, the value is 1; if there are short position, the value is -1; if there are no position, the value is 0.
- Get Bollinger Band data
Next we need to calculate the values of the upper, middle and lower rails of the Bollinger Band indicator. we need to get the Boolean array first, and then get the values of the upper, middle, and lower rails from this array. In the FMZ quant tool, it is very simple to get the Boolean array, just call the Bollinger Band API directly, it is a two-dimensional array.
It is easy to understand the two-dimensional array, which is the array in a array. The order to obtain the value is: first obtain the specified array in the array, and then obtain the specified element from the specified array, as shown below:
```
var arr = [[100, 200, 300],[10,20,30],[1,2,3]]; // this is a two-dimensional array
var test = arr[0]; //first obtain the specified array in the array and assign the value to variable "test"
var demo1 = test[0]; //then get a value from the test array
demo1; // the result is : 100
var demo2 = arr[0][0]; // you also can write like this
demo2; // the result is the same : 100
```
Below, from 13th to 19th lines are getting the Bollinger Band upper, middle and lower rail coding part, Wherein the line 13 is used the FMZ Quant API tool, which can accessing the Bollinger band array directly; line 14 to line 16 are obtaining the two-dimensional array respectively for the upper, middle and lower rail array; line 17 to line 19 are getting the specify value from the upper, middle, and lower rail array.
```
function main() {
$.CTA("this_week", function(st) {
var r = st.records; // get the k line data
if (r.length < 20) return; // filter the length of k line data
var close = r[r.length - 2].Close; // get the previous k line closing price
var time = new Date(r[r.length - 1].Time); // according the current k-line timestamp, create a time object
var isClose = time.getHours() == 14 && time.getMinutes() == 45; // judging whether the current k-line is 14:45. this is just a example, you can specify any time you want during the 24 hours
var mp = st.position.amount; // get the holding position information
var boll = TA.BOLL(r, 20, 2); //calucating the Bollinger Band indicator
var upLine = boll[0]; // get the up-rail array
var midLine = boll[1]; // get the middle-rail array
var downLine = boll[2]; // get the lower-rail array
var upPrice = upLine[upLine.length - 2]; // get the previous K-line upper rail value
var midPrice = midLine[midLine.length -2]; // get the previous K-line middle rail value
var downPrice = downLine[downLine.length -2]; // get the previous K-line lower rail value
})
}
```
### Step 3: placing order and trade
With the above data, we can write the trading logic and placing order part now. It is also very simple, the most commonly used is the "if statement", which can be described as: if condition 1 and condition 2 are true, place the order; if condition 3 or condition 4 is are true, place the order. As shown below:
```
function main() {
$.CTA("this_week", function(st) {
var r = st.records; // get the k line data
if (r.length < 20) return; // filter the length of k line data
var close = r[r.length - 2].Close; // get the previous k line closing price
var time = new Date(r[r.length - 1].Time); // according the current k-line timestamp, create a time object
var isClose = time.getHours() == 14 && time.getMinutes() == 45; // judging whether the current k-line is 14:45. this is just a example, you can specify any time you want during the 24 hours
var mp = st.position.amount; // get the holding position information
var boll = TA.BOLL(r, 20, 2); //calucating the Bollinger Band indicator
var upLine = boll[0]; // get the up-rail array
var midLine = boll[1]; // get the middle-rail array
var downLine = boll[2]; // get the lower-rail array
var upPrice = upLine[upLine.length - 2]; // get the previous K-line upper rail value
var midPrice = midLine[midLine.length -2]; // get the previous K-line middle rail value
var downPrice = downLine[downLine.length -2]; // get the previous K-line lower rail value
if (mp == 1 && (close < midPrice || isClose)) return -1; // if holding long position, and the closing price is less than the mid-rail, or the current time is 14:45, closing long position.
if (mp == -1 && (close > midPrice || isClose)) return 1; // if holding short position, and the closing price is greater than the mid-rail, or the current time is 14:45, closing short position.
if (mp == 0 && close > upPrice && !isClose) return 1; // if there are no holding position, and the closing price is greater than the upper-rail, or the current time is not 14:45, open long position.
if (mp == 0 && close < downPrice && !isClose) return -1;// if there are no holding position, and the closing price is less than the lower-rail, or the current time is not 14:45, open short position.
})
}
```
In the above figure, lines 21 to 24 are the trading logic and placing order coding part. From top to bottom they are: closing long position, closing short position, open long position and open short position.
Take the open long position as an example. This is an "if statement". If only one line of code is executed in this statement, the curly braces " {} " can be omitted. The statement is translated into text meaning: if the current position is 0 and the closing price is greater than the upper rail, and the k-line time is not 14:45, then " return 1 "
you may find that these lines have " return 1 " and " return -1 ", which is a fixed format, meaning: if it is the buying direction, write " return 1 "; if it is the selling direction, write " return -1 ". opening long position and closing short position are all buying direction, so write "return 1"; and vice versa.
## Complete Strategy code
At this point, a complete strategy code is written. If the trading framework, trading data, trading logic and placing order are written separately, it is very simple? The following is the entire code of this strategy:
```
function main() {
$.CTA("this_week", function(st) {
var r = st.records; // get the k line data
if (r.length < 20) return; // filter the length of k line data
var close = r[r.length - 2].Close; // get the previous k line closing price
var time = new Date(r[r.length - 1].Time); // according the current k-line timestamp, create a time object
var isClose = time.getHours() == 14 && time.getMinutes() == 45; // judging whether the current k-line is 14:45. this is just a example, you can specify any time you want during the 24 hours
var mp = st.position.amount; // get the holding position information
var boll = TA.BOLL(r, 20, 2); //calucating the Bollinger Band indicator
var upLine = boll[0]; // get the up-rail array
var midLine = boll[1]; // get the middle-rail array
var downLine = boll[2]; // get the lower-rail array
var upPrice = upLine[upLine.length - 2]; // get the previous K-line upper rail value
var midPrice = midLine[midLine.length -2]; // get the previous K-line middle rail value
var downPrice = downLine[downLine.length -2]; // get the previous K-line lower rail value
if (mp == 1 && (close < midPrice || isClose)) return -1; // if holding long position, and the closing price is less than the mid-rail, or the current time is 14:45, closing long position.
if (mp == -1 && (close > midPrice || isClose)) return 1; // if holding short position, and the closing price is greater than the mid-rail, or the current time is 14:45, closing short position.
if (mp == 0 && close > upPrice && !isClose) return 1; // if there are no holding position, and the closing price is greater than the upper-rail, or the current time is not 14:45, open long position.
if (mp == 0 && close < downPrice && !isClose) return -1;// if there are no holding position, and the closing price is less than the lower-rail, or the current time is not 14:45, open short position.
})
}

There are two things need to be notice:
- Try to (but not necessarily) write the strategy logic as the current K-line condition is established, then placing the order on the next k-line. Or the previous k-line condition is established, placing orders on the current k-line, in this way, the result of the backtest and the real market performance are not much different. It is OK to not write like this, but pay attention to whether the strategy logic is correct.
- In general, the logic of closing position should write in front of the opening position logic. The purpose of this is to try to make the strategy logic meet your expectations. For example, if the strategy logic just meet the situation where it need to do the opposite direction of trading after just close a position, the rule of this kind of situation is to close the position first and then open the new position. If we write the closing position logic in front of the opening position logic, it will perfectly fullfil this rule.
## To sum up
Above we have learned each step of developing a complete intraday quantitative trading strategy, including: strategy introduction, Bollinger indicator calculation method, strategy logic, trading conditions, strategy code implementation, etc. Through this strategy case, not only we familiar with the programming methods of the FMZ Quant tools, but also can build some other strategies that are adapted according to this template.
Quantitative trading strategy is nothing more than a summary of subjective trading experience or system. If we write down the experience or system used in subjective trading before writing the quantitative strategy, and then translate it into code one by one, you will find that the writing a quantitative strategy will be much easier.
## Next section notice
In quantitative trading strategy development, if only can choose one programming language, without hesitation, it must be Python. From getting data to backtesting, even the placing order part, Python has covered the entire business chain. In the field of financial quantitative investment, Python has occupied an extremely important position, the next section of the course we will begin to learn the Python language.
## After-school exercises
1. Try to use the knowledge in this section to implement a double moving average strategy.
2. Try to implement the KDJ indicator strategy using the JavaScript language on the FMZ Quant platform.
