Hello,

I’ve just finished “Blue at the Mizzen” and I was wondering what your opinion is on the unfinished book is….

Have you read it? Would you recommend reading it or not?

I am so sad to be at the end of the books but ending on Jack so happy and relieved might be the best place to stop?

Would really value your opinion as I know you know the books well.

Warmly,

Rosanna

Ooh this is a tough one - because my own approach (thus far) is not one I’d necessarily recommend? The thing is: I have not read it.

However! Complicated reasons for that. One is a personal weirdness of mine where I am oddly resistant to watching or reading the ‘final’ instalment of a thing. I have noticed myself doing this a lot: I’ll just leave the very last episode unwatched, the last book in a long running serialised saga unread. This is not a recommended practice, it’s what I’d call ‘a super dumb thing to do’, and I’d categorise that as a symptom (of what? Who knows! I’m an undiagnosed delight). Is it because if they fumble the last instalment it leaves a bad taste for the whole series? Maybe. Is it because if there’s still one left, then there’s still Something Out There and the experience of discovering new writing isn’t over yet? Could be! Anyway, it’s a silly thing to do and I don’t recommend it as an approach to media. Go forth and read!

Having said that, I do have an aversion, generally, to publishing bits and pieces of an author’s notes as though it were finished work. I think it feels like being asked to have the mindset where a creative endeavour is ‘content’ to consume, rather than a constructed, deliberate work - “it’s their words and you want more words! So here’s more!”. O’Brian seems, from the work, and from interviews, to be a bit of an exacting, deliberate sort of creator - taking 3 chapters of some unedited typescript and adding some handwritten elements that didn’t even get to editing stage feels uhhhhh vaguely intrusive? Ahhhh why am I like this, that’s not even a reasoned response, and should not be taken as direction lol. I should back away slowly from this sort of parasocial contortion!

Like, I’m all for publishing someone’s essays, collected letters, all kinds of ephemera - that’s it’s own thing. But taking something which is a specifically a work In Progress, and publishing it as though it were a presentable book (a voyage of Jack Aubrey), didn’t really appeal to me. Which is contradictory of me as I do enjoy artists proofs, sketchbooks, and unfinished paintings! I contain multitudes.

At the end of the day it felt a bit like the publisher going “I’m going to tell you a new Aubreyad story, but we don’t know if O’Brian was going to tell it in this way, really, and also I’m going to stop partway through” which I didn’t fancy experiencing. So, at this point I tend to finish up at 20 and go back to 1. Never say never though - maybe the various editor’s notes, forewords, and afterwords would help me enjoy it as a fragment, rather than a presented work. It’s at least 3 chapters of (more or less) O’Brian prose, which is better prose than one often finds.

Please don’t let me stop you for any reason. Read on! If you go ahead and read it, post your thoughts?

A Step-by-Step Guide to Hiring Angular Developers for Your Startup

Angular is frequently the preferred option for companies looking to develop online applications that are responsive, scalable, and quick. Because of its component-based architecture and TypeScript foundation, Angular—which was created and maintained by Google—is perfect for complicated applications requiring great performance. 

However, you need more than just the proper framework to fully utilize Angular; you also need the right people. This useful advice will assist you in hiring Angular engineers who share the goals and pace of your firm.

Building Your Frontend Right: How Startups Can Efficiently Hire Angular Talent

Understand Why Angular Fits Your Startup

Verify if Angular is a good fit for your project before hiring. Angular is great for scalable systems, enterprise dashboards, and single-page applications (SPAs). Dependency injection and two-way data binding are two of its built-in features that help speed up development if you're creating an MVP or anything that will expand rapidly.

Hiring for the correct technical stack and future requirements is ensured when you have a clear understanding of why you need to hire Angular developers.

Define the Skills You Need

Over time, angular has changed dramatically. Every version of Angular, from AngularJS to Angular 15+, has included new functionality and syntax. Effective hiring of Angular developers requires applicants who:

Know JavaScript and TypeScript well.

Understand how to integrate RESTful APIs.

Able to use technologies like RxJS or NgRx to handle state

Understand testing frameworks such as Karma or Jasmine

Be familiar with cross-browser compatibility and responsive design.

Knowing which abilities are most important helps you narrow down your search, even though you don't always need someone who has all the answers.

Tap Into the Right Hiring Channels

Examine both conventional and contemporary hiring methods to identify the best applicants. LinkedIn, GitHub portfolios, and tech-focused job forums are all excellent starting points. However, working with an IT staffing agency can be a wise choice for companies with constrained bandwidth. 

These organizations assess applicants beforehand and frequently have access to specialized Angular talent around the world. Actually, a lot of tech organizations use staffing agencies to speed up onboarding and minimise hiring friction.

Evaluate Remote Options

Finding skilled local developers within their budget is a common challenge for startups. Both issues can be resolved by choosing to hire remote talent and broadening your reach. With the correct tools and communication techniques, remote Angular devs may be just as productive, if not more so.

Nowadays, a lot of software organizations prioritize remote work since it allows them to access a global talent pool without sacrificing quality.

Use a Practical Interview Process

Don't take the whiteboard tests. Instead, concentrate on real-time coding challenges and portfolio reviews. Examine the candidate's abilities to solve problems, write clean code, and be familiar with version control systems like Git. During the interview, request that applicants use Angular to construct or describe minor features.

Remember to evaluate their communication abilities as well, particularly if you are hiring from a distance. Working together is essential for early-stage startups.

Onboard With a Growth Mindset

Make sure when you hire software developers they are successful. Establish your IT stack and project objectives, write clear onboarding documents, and plan frequent check-ins. Provide access to courses or Angular community events to promote lifelong learning.

Hiring is crucial, but so is retention. The likelihood of a supported developer sticking around and expanding with your firm is higher.

Closing Remarks

Making the correct hires may make or destroy your business while you're growing quickly. You can hire Angular developers that will genuinely contribute to the long-term success of your firm by emphasizing role clarity, reaching out to talent around the world, and utilizing practical ways to assess applicants. 

For today's high-growth tech organizations, investing in Angular knowledge is a smart choice, whether done directly or through an IT staffing agency.

React vs Angular: Choosing the Right Framework for Global Web Applications

In the fast-paced world of global software innovation, choosing the right frontend framework can make or break your digital product. When businesses invest in web application development services, one of the most crucial decisions they face is whether to build with React or Angular. Both are powerful tools that dominate modern web development, but they offer distinct advantages based on project scope, team expertise, and business goals—especially when targeting global markets like the USA, UK, UAE, and Australia.

Understanding the Basics: React and Angular

React, developed by Facebook, is a JavaScript library focused on building UI components. It’s lightweight, component-based, and known for its speed and flexibility. React is often chosen for high-performance single-page applications (SPAs) and is backed by a massive community.

Angular, on the other hand, is a full-fledged frontend framework maintained by Google. Unlike React, it comes with everything out of the box—routing, HTTP services, form handling, and more—making it a more opinionated and structured option for large-scale enterprise projects.

Key Differences That Matter Globally

1. Learning Curve & Development Speed

React offers more flexibility but comes with the responsibility of assembling your tech stack—developers need to choose their own libraries for routing, state management, etc. This is great for experienced teams that want freedom, but it can be overwhelming for beginners.

Angular, being a complete framework, provides a consistent development environment. However, its learning curve is steeper due to its use of TypeScript and in-depth structure.

👉 Ideal for Global Teams: If you're managing a distributed team or outsourcing development to multiple regions, Angular's structure may help standardize development practices across borders.

2. Performance & Scalability

Both frameworks deliver excellent performance when used correctly. React's virtual DOM ensures minimal re-rendering, which is ideal for dynamic and interactive UI-heavy applications.

Angular, although slightly bulkier, handles large-scale, feature-rich applications very well. With Ahead-of-Time (AOT) compilation, lazy loading, and modularization, Angular apps can be highly optimized for enterprise-scale systems.

👉 Use Case Insight: For real-time dashboards, SaaS platforms, or media apps targeting global users, React may offer faster load times. But for comprehensive, scalable business platforms with complex data flows, Angular could be the better choice.

3. Community & Ecosystem

React has a larger community and a wider range of third-party libraries. Its flexibility allows integration with other tools, making it highly adaptable for varied project requirements.

Angular's ecosystem is more self-contained and less reliant on third-party tools. While this ensures stability, it can sometimes limit flexibility for unique use cases.

👉 Developer Availability Globally: React developers are generally easier to find across major tech markets like the US, UK, and Australia. This may speed up hiring and reduce development costs.

4. Maintenance & Long-Term Support

Angular provides long-term support and regular updates from Google, making it a strong choice for enterprise clients that prioritize stability and security. React also offers excellent support and frequent updates, though the burden of managing dependencies lies more on the development team.

👉 Security & Compliance: For industries like finance or healthcare that must comply with strict regulations, Angular’s built-in features can reduce reliance on third-party packages, enhancing security.

Which Framework Is Best for Global Web Applications?

There’s no universal winner—your choice depends on your business needs:

Choose React if:

You want lightweight, flexible UI for fast-growing products

You’re building a fast MVP or an interactive frontend for global users

You need to hire developers quickly across multiple regions

Choose Angular if:

You’re building a robust enterprise-level application

You need a standardized framework for a large, international team

You require strong built-in tools and security features

Final Thoughts

For global companies looking to scale their digital presence, the right frontend framework can significantly influence speed to market, performance, and maintainability. Both React and Angular are excellent choices—but aligning your decision with your team structure, long-term goals, and project complexity is essential.

At the end of the day, choosing between React and Angular should be a strategic move—guided not just by popularity, but by how well the framework aligns with your web application’s objectives across international markets.

If you’re unsure which technology fits best with your business model, a professional web application development company can guide you through a detailed technical assessment and help you build a future-ready digital product that delivers performance, scalability, and global reach.

Hiring Solana Developers 101: A Beginner’s Guide

As blockchain adoption progresses rapidly, high-performance platforms like Solana are presently being explored by enterprises to be the infrastructure for their decentralized applications. Considered to be fast, Solana is attractive for developers and entrepreneurs due to its high speed and low fee structure. With that said, development on Solana would require certain special expertise, and hence knowing where and how to Hire Solana developers becomes an important factor for success in your project. Whether it's a DeFi platform, NFT marketplace, or a Web3 tool, this guide is an easy way to sail through with the confidence to conduct the whole hiring process.

Why Solana? A Quick Overview

Solana stands apart in the ecosystem due to its scalability and efficiency. Where other chains struggle with congestion and high gas fees, Solana can manage more than 65,000 transactions per second with the introduction of Proof of History (PoH) and Sea Level, a parallel execution engine. This brings about the best environment for real-time applications, gaming, financial protocols, and high-volume NFT drops.

Further, Solana enjoys a secured and rapidly growing ecosystem, unlike other chains. Projects like Magic Eden, Phantom Wallet, and Marinade Finance truly demonstrate its potential. Hence, knowledge of factors such as the usage of Rust or C and an understanding of Solana's very different runtime environment will greatly enhance your hiring abilities to find developers that will take full advantage of these benefits.

When Do You Need a Solana Developer?

Hiring a Solana developer becomes extremely essential when the use case requires decentralized logic or blockchain-based storage. A few of the occasions when hiring a Solana developer becomes wise are:

Identifying a dApp: Be it a game, a financial tool, or something else, any application decentralized on Solana needs a developer who is an expert in smart contract design.

NFT Projects: Developers can help you build, mint, and operate NFTs and marketplaces that run natively on Solana.

DeFi Protocols: From staking contracts to liquidity pools, you'll need specialists to write and deploy secure contracts for finance.

Data-Oriented Applications: Developers can build an analytics dashboard or an analytics tool that interacts with Solana nodes and RPC endpoints.

Porting from Ethereum: When moving an already existing app to Solana for lower fees, skilled developers will be the ones to tackle all compatibility and performance adjustments.

Top Skills to Look For in Solana Developers

Getting somebody who just "knows blockchain" is just not enough; for development on the Solana network, you will have to hire a developer with the following skill set:

Rust Programming Proficiency: Solana smart contracts, called on-chain programs, are mostly written in Rust, which poses a steep learning curve but offers the best performance and safety. The developer should profess knowledge of practical experience with the language. 

Anchor Framework Proficiency: Anchor framework eases development by providing macros and eliminating boilerplate code, thus accelerating dApp delivery. A developer experienced with Anchor works faster and writes much cleaner, testable code.

Frontend and Wallet Integration: Expertise in linking Solana smart contracts to frontend apps through JavaScript or TypeScript libraries (e.g., Solana Web3.js) is essential. Integration with wallets such as Phantom, Solflare, or Backpack will also be needed for genuine test uses.

Security Best Practices: With hacking and exploits happening so frequently in Web3, it is critical that your developer know how to audit, write secure logic, and utilize tools such as Solana Playground or Devnet for safe testing. 

Solana Dev Tools: Knowledge of CLI tools, explorer APIs, RPC calls, test validators leads to easier development and debugging.

Where to Find Solana Developers

Finding the appropriate developer is always a task; with a strategic approach, you can reach out to either individuals or teams that are truly talented. Here lies where to begin your search:

Freelance Platforms: Sites like Upwork, Toptal, and Fiverr Pro are places to find developers who may have Solana experience. Look for profiles that are verified; portfolios and reviews of clients are also important. 

Community Hubs: Join the official Solana Discord, look for active developers on GitHub, and take part in discussions on Stack Overflow, Solana Stack Exchange, or Reddit r/solana. 

Web3 Job Boards: Such niche sites as CryptoJobs, Web3.career, and Remote3 let you post jobs and connect with developers who are into blockchain tech already. 

Hackathons & Meetups: Solana hosts almost yearly hackathons that top emerging talent tends to flock to. You could scout developers that have won or placed through these competitions. 

Development Agencies: If you are running on time, partner with a Solana-focused agency that will provide full-stack dApps, project managers, and comprehensive QA support.

How to Evaluate and Interview Candidates

Inappropriate hiring and selection may lead to delays and low-quality code, or in some cases, security vulnerabilities. Here's how to screen top Solana talent:

Look at Their Portfolio: Request work done previously using Solana or dApps. Look for live demos, GitHub repositories, deployment of smart contracts on Mainnet or Devnet.

Technical Fit: Questions may concern Solana architecture, handling of state changes, cross-program invocations (CPIs), and optimizations for rent and compute units.

Give Them a Mini Project or Coding Assignment: Small tasks such as creating a simple token, setting up an SPL wallet, or coding a staking contract can be considered. In addition to code quality, evaluate their approach to solving problems.

Communication Skills Test: Working remotely? Documenting work done, reporting bugs, and collaborating using Git, Slack, or Notion tools require as much importance as technical skills.

Common Hiring Models

The hiring model has advantages and disadvantages that apply depending on how complex your project is, how megabucks you intend to budget, and how long you've got for working out a timetable for production itself. Here is a quick breakdown:

Freelancer: Use one for a short piece of work or MVP development. Flexibility and cost are in their favor, but the downside is that freelance contractors are not willing to commit forever.

Inhouse Developers: They stand ideally prepared for startups and growing companies with a continuous blockchain need. They also get involved in your product strategy.

Agencies or Dev Shops: These tend to suit non-technical founders or companies needing full-scale development. Design, QA, project management, and maintenance might also be part of the package.

Look at what you want to achieve, and pick the one suited for your development roadmap and operational needs.

Conclusion

Solana is one of the most scalable and least expensive blockchains in the world, hence an ideal choice for developers of demanding Web3 applications. Because of the complexity of the environment, one does not just need any generalist developer but a developer versed with Solana's unique architecture and tools and its best practices.

If you want to develop a commercially viable dApp or ramp up an NFT platform, devoting the right talent is of essence. So, at the end of this guide, you will know how to fairly evaluate skills, vet candidates, and ultimately Hire professional Solana Developers who can swiftly convert your vision from concept to reality with speed, security, and scalability.

React JS Development: The Ultimate Guide to Building Modern Web Applications

In the rapidly evolving world of web development, building fast, interactive, and scalable applications is no longer optional—it's essential. Among the many technologies available today, React JS development has emerged as a top choice for developers and businesses alike. Created by Facebook, React.js simplifies front-end development while delivering a superior user experience.

Whether you're a business owner exploring tech options or a developer seeking efficient tools, this guide covers everything you need to know about React JS development, its advantages, real-world applications, and why it continues to dominate the front-end ecosystem.

What is React.js?

React.js is an open-source JavaScript library used for building user interfaces—particularly single-page applications (SPAs). It allows developers to create reusable UI components that update in real time as data changes.

Unlike traditional web frameworks that manipulate the DOM (Document Object Model) directly, React uses a virtual DOM to optimize updates, making apps faster and more responsive.

Key Features of React JS Development

1. Component-Based Architecture

React promotes modular development. Instead of building large monolithic pages, developers create reusable components that make development faster and more organized.

2. Virtual DOM for High Performance

React’s virtual DOM efficiently updates only the changed parts of the UI, improving performance and reducing unnecessary re-renders.

3. Unidirectional Data Flow

Data flows in one direction, making application behavior more predictable and easier to debug.

4. JSX Syntax

JSX (JavaScript XML) allows developers to write HTML-like code within JavaScript, making UI code easier to read and maintain.

In order to improve test coverage, identify defects early, and guarantee more seamless deployments, more tech organizations are opting to hire Jest developers.

Hiring a Jest expert could increase product stability and drastically reduce release timelines if your team is having trouble with faulty tests, inadequate coverage, or drawn-out QA cycles.

Strengthen Code Quality and Ship Faster with Better Testing Strategies

Let’s first understand the reasoning behind choosing Jest. 

Jest is renowned for its ease of use, quickness, and integrated mocking features. It was developed by Meta and is best suited for unit testing TypeScript and JavaScript applications, particularly React applications. Jest facilitates rapid feedback loops, code coverage tracking, and snapshot testing with no setup and a robust ecosystem.

Hiring Jest developers adds a person who is capable of:

Creating test suites that are dependable and manageable.

Boosting code coverage without reducing development speed.

Including tests in pipelines for CI and CD.

Identifying edge cases that are frequently overlooked.

It’s time to now get to specifics.

How a Jest Developer Can Boost Test Coverage by 40%

Developers write tests on the fly for the majority of development teams. However, test coverage frequently stagnates in the absence of adequate concentration. You can increase total coverage by 30–40% by having a professional Jest developer examine your current test suite, find gaps, and rewrite any weak or missing tests.

By establishing reusable patterns, checking pull requests for test completion, and mentoring others on best practices, they also enhance the team's testing culture. This results in more stable releases, agile development cycles, and fewer hotfixes for tech corporations.

Skills to Look for When You Hire Jest Developers

A competent Jest developer should know how to:

React with JavaScript/TypeScript (or comparable frontend frameworks)

Creating integration, snapshot, and unit tests

Mocking APIs and testing asynchronous code

Configuring test environments and coverage thresholds

Using CI systems (such as GitHub Actions and CircleCI) and tools like ESLint and Prettier

Bonus points are awarded for knowledge of testing libraries such as Cypress for end-to-end testing or the React Testing Library.

Collaborating Across Teams

Jest developers frequently collaborate closely with DevOps, frontend, and backend engineers. Make sure that everyone on your team is aware of the testing documents and standards if you intend to hire software developers in addition to QA-focused engineers.

Nowadays, a lot of tech organizations hire for hybrid roles, where a developer adds long-term value with each sprint by contributing to both core features and test coverage.

Use an IT Staffing Agency to Speed Up Hiring

There is a demand for Jest competence. By collaborating with an IT staffing agency, you can access a talent pool that has already been thoroughly screened. Agencies often have access to candidates that are experienced working with elite product teams and have an understanding of both speed and quality.

This method helps you scale your engineering team with a proper testing mindset while saving time on screening.

Summing Up

Future hours can be saved by investing in test automation now. By hiring Jest developers, you're doing more than just filling a position; you're strengthening your codebase, increasing team confidence, and providing users with better products. Smart testing is a competitive advantage for contemporary tech companies, not a luxury.

Integrating Native Modules in Hybrid Apps: A Step-by-Step Guide 

In today's rapidly evolving tech landscape, hybrid app development has gained immense popularity due to its cost-effectiveness and cross-platform capabilities. Businesses increasingly prefer hybrid frameworks like React Native, Flutter, and Ionic to streamline development without sacrificing user experience. However, while hybrid apps offer flexibility, they sometimes fall short in accessing device-specific features efficiently. That’s where integrating native modules becomes essential. 

This blog walks you through the step-by-step process of integrating native modules in hybrid apps to enhance performance and functionality without losing the benefits of cross-platform development. 

Why Integrate Native Modules? 

Hybrid apps are built using web technologies, but when it comes to device-level capabilities—like accessing the camera, Bluetooth, sensors, or high-performance animations—web code might not be enough. Native modules bridge this gap by allowing developers to write platform-specific code (Java/Kotlin for Android, Swift/Objective-C for iOS) and call it from the hybrid layer. 

This approach improves app performance, unlocks advanced device features, and delivers a more native-like experience to users. 

Step-by-Step Guide to Integrating Native Modules 

1. Identify the Requirement 

Before jumping into coding, evaluate what native functionality is needed. For example: 

Accessing device sensors (accelerometer, gyroscope) 

Background tasks 

Complex animations or gestures 

Bluetooth integrations 

Once the need is identified, determine if existing plugins or libraries support it. If not, proceed to write your own native module. 

2. Set Up the Native Environment 

Depending on your hybrid framework, you’ll need to set up native development environments: 

React Native: Android Studio + Xcode 

Flutter: Android Studio + Xcode 

Ionic/Cordova: Node.js, Android SDK, Xcode, and relevant CLI tools 

Make sure your environment is correctly configured for both Android and iOS builds. 

3. Write Native Code 

Now comes the core part: writing native code. 

Android: Create a new Java or Kotlin class that extends the appropriate module class. 

iOS: Create a Swift or Objective-C class implementing the required bridge protocols. 

Ensure this native module exposes methods or events you want to use in your hybrid code. 

4. Bridge Native Module to Hybrid Code 

Use your hybrid framework’s bridging mechanism: 

React Native: Use the NativeModules API to expose native functions to JavaScript. 

Flutter: Use MethodChannels to communicate between Dart and native code. 

Ionic: Use Capacitor or Cordova plugins to integrate native functionality. 

This is the layer where your JavaScript/Dart/TypeScript code talks directly to your native module. 

5. Testing Across Platforms 

After successful integration, test the functionality on both Android and iOS devices. Ensure consistent behavior and handle any platform-specific nuances. 

Pro Tip: If you're unsure how your budget aligns with these technical enhancements, use a mobile app cost calculator to estimate expenses before diving into native module integration. 

6. Handle Errors and Platform Limitations 

It’s important to gracefully handle scenarios where a feature is not available on one platform. Build fallbacks or conditional code execution based on the OS or device capabilities. 

7. Optimize and Maintain 

Regularly update native modules to align with OS updates. Unmaintained native code can lead to app crashes, rejections from app stores, or security vulnerabilities. 

Best Practices 

Keep the native code modular and well-documented. 

Avoid bloating your hybrid app with too many native modules unless necessary. 

Leverage community-tested plugins when possible, but vet them for security and updates. 

Monitor performance to ensure that native modules are not negatively impacting app speed or memory usage. 

Real-World Use Case 

Imagine a fitness app that requires real-time motion tracking. A hybrid app alone may lag in accurately capturing movement, but by integrating a native module to tap directly into accelerometer and gyroscope sensors, you can dramatically improve tracking accuracy and responsiveness. 

This is just one of many scenarios where hybrid apps shine brighter when empowered with native capabilities. 

Book an Appointment with Our Experts 

Integrating native modules can be tricky without deep knowledge of both mobile platforms. If you're unsure where to start or how to do it right, Book an Appointment with our experienced mobile developers today. We'll help you tailor the perfect strategy for your app. 

Conclusion 

As hybrid app frameworks evolve, the need to blend native capabilities with cross-platform logic will only grow. By understanding and implementing native modules, developers can create high-performing, feature-rich apps without going fully native. 

Looking to upgrade your hybrid application or start a new project from scratch? Our team offers top-notch hybrid app development services tailored to your business needs.
