Microsoft XBOX 360 - Sonic World Adventure (Sonic Unleashed)

Title: Sonic World Adventure / ソニック ワールドアドベンチャー

Developer/Publisher: Sega (Sonic Team)

Release date: 19 February 2009

Catalogue No.: HEC-00002

Genre: 3D Action Adventure

Sega's Sonic team development division, learning from Sonic 06's mistakes, made the XBOX 360 perform some pretty impressive tasks in their demos, some of which were used in their games. Sonic Unleashed is one of those games (the other one being 2019's Shin Sakura Taisen, a visual novel for the PS4). The game marks the first-ever time a Sonic game debuted with a rendering system dubbed by Sonic Team as the "Hedgehog Engine", designed specifically to handle the drawing of 3D geometry and environments in a fast-paced setting. (The game still uses CRI Middleware and Havok technologies in some parts).

As a result, compared to the likes of Sonic 2006, Sonic Unleashed is capable of producing CGI film quality graphics very similar to those from the best Disney/Pixar animated film properties. Yoshihisa Hashimoto who was the Director of this game at the time, spent months analyzing video games, CGI films, and even people and places in real life. He came to the conclusion that current-generation games are missing an element known in the computer animation field as Global Illumination.

This allows for a light source to hit a scene, and light is reflected off every object in the environment. To cover the vast amounts of calculations that needed to be processed, they also came up with a system that connected 100 computers for the team to distribute the workload. This enabled them to complete all the lighting calculations for an action stage (which is about 6-8 miles long) in 2 or 3 days.

Hashimoto's team also developed a technology called Light Field, which blended the characters naturally into the environments. With this technology, Sonic can run through an action stage while the light is being reflected off him naturally as if he “belongs” there (in contrast to past games where Sonic looks out of place in several environments). As a result, Sonic Unleashed manages to stand out from the rest of the platformers of its age in that rather than lowering the quality down to PS2 levels (as was the case with some early PS3 and 360 games around 2005-2007), the game uses pseudo-raytracing, coupled with the introduction of the then-novel Boost gameplay mechanic and a custom control scheme dedicated to the Werehog/Night levels, as well as a seamless day/night cycle to provide fast and smooth looking 3D environments.

Coupled together with the XBOX 360's great sprite and polygon capabilities for enemies and explosions and polygon-built ships (mainly those from Dr. Eggman), along with the PS1-quality ease of development that made the XBOX 360 the king in the eyes of general gamers, makes Sonic Unleashed look like quite a feast for the ears, as well as the eyes.

So how does it play? Well, I'm not too sure if it went down well in Malaysia but judging by how hard it is to find a copy, I'd say it wasn't well received (in my area). Most households in Malaysia probably only owned a PS2 back in the day, so the PS2 version of Unleashed is much more common. Globally though, and on the Sonic circles, I remember Sonic Unleashed being showered with praise the world over, with high critic scores and glowing fan and user reviews. This could be because Sonic Unleashed fixed the flawed controls that plagued '06 and turned the franchise's reputation from being stained into a great sendoff for the future, with great gameplay, a killer story, and an AWESOME mix of orchestral, rock, and miscellaneous soundtrack genres as you played all the way from Apotos (based on Mykonos, Greece) to Eggmanland (based on Luna Park Sydney).

There is a lot to blast and search for as well as getting yourself lost quite often in the Open World Hubs (^o^;) Oh and about the gameplay, the Daytime stages are some of the BEST that you'll ever see in terms of graphical fidelity (only bested by Frontiers, Shadow Generations, and the upcoming Crossworlds), and the Werehog stages, it's debatable, but it is pretty good to me. It's not 100% perfect though - there are some minor flaws such as very weird frame-rate issues, and falling down easily when using your ring energy, the Werehog levels can be very long but not as bad as other worse beat-em-ups on the 360 such as TMNT Turtles in Time Re-Shelled and Golden Axe Beast Rider. I wanted to call it "God of War inspired" but that would be me pulling the Sony fanboy card. Let's just say the combat reminded me of either Spike Out, Streets of Rage, or even Batman Returns on the Super Famicom, maybe a touch of Arkham Asylum and Arkham City (though these are later games). You need to replay levels to get the medals which become harder to find.

Bottom line, if you're into the odd type of action platformer with a killer story, then I think Sonic Unleashed will suit you. This game is compatible with XBOX ONE and XBOX SERIES consoles, and if you play it on an XBOX SERIES S or X, you get the added bonus of 60 FPS boost mode which is really awesome.

You hear about video game development?

Well. I wouldn't say I expected such a catastrophic implosion from Unity.

Now, I can't say that I didn't laugh at the situation. It's a hilariously terrible case of bad management coming up with bad ideas in desperation. But it's also a somewhat scary indication of the sorry state of the industry.

Unity controls about 40% of the engine marketshare (according to a linkedin post I found anyway). Unity dominates the engine scene by a large margin, followed by Unreal at around 30% and Cryengine by around 5%. Unity forms such a large part of the entire game development industry, that it's difficult to really even understand just how much they control the concept of games as a whole!

Most people are jumping to some paid alternatives, like the aforementioned Unreal and, to a lesser extent, Game Maker, but my suggestion is this: don't!

Within the last decade, all-encompassing closed super game engines have become less of a side venture and more of an expectation. Back in the 2000s, there were a few engines like this, mostly amateur ones. Game engines were less creation stations and more of a loose collection of middleware and tools. Purchasing the rights to the engine meant that you also got the responsibility of also tying the engine into something resembling a game yourself. I feel like this art has been lost.

Game engines nowadays are more of a purchase of a passing right to use and incredibly specific, closed set of tools. You don't get to define the tools, and you don't get to really own the tools. It's yet another example of the tradition of the games industry fucking over the customers, and the customers just going with it. Because of this, while Unreal got some free dunks on Twitter for this, I can assure you Epic is planning something equally terrible as Unity's PR faux pas, and it'll come into to play in about 3 years when everyone's just accepted that Unity sometimes financially screws you over.

But, game developers are indeed developers. They know software, and they can learn to make new software.

If you're a game dev and still reading this, I'd recommend taking a peek beyond the curtains of corporate cockfighting, into the realm of DIY game engines. It's a… somewhat janky world full of strange characters with unusual ideas on how much time it's acceptable to spend not working on a game, but it's also a place where you're not being sat on by fatcats.

Just as game engines have progressed in the past 20 years, so have libraries, middleware and resources for independents. Making your own engine isn't just picking up ANSI C and toiling for a year in software rendering hell. Open tools like Pygame, Monogame, LÖVE and Cocos2D (among many, many others) are far beyond just simple rendering libraries and border on being game engines sometimes. The difference is, these tools are open source, and they do not restrict you with what you can do with them.

There are several games you may have played made using these frameworks. Streets of Rage 4 (MonoGame), Celeste (MonoGame), Fez (XNA, aka. MonoGame), Miitomo (Cocos2D), Geometry Dash (Cocos2D)… I got tired of looking up more. There are a lot of games.

The future which I hope to see for game developers is one where you have a large assortment of simple tools you can pick. Level editors, asset converters, entity systems, all small chunks of a game engine you could drop into your own project to slowly build up your own collection of workflows to make games your own way, completely independent of any larger forces on the market.

The support for these frameworks is still somewhat barren compared to Unity, but I believe, that if more people jump to alternatives like this, more tools, tutorials and middleware built for them would start showing up. This is how Unity also got its start, about 15 years ago. You also really don't need all the power in the world to make your simple 2D Megaman clones. The fog created by the monolithic engines we have now have obscured just how simple the building blocks for your favourite games can really be.

It just takes some bravery and willingness to learn a new way to approach making games, but I think the outcome is worth it, even just for you.

"Vulkan is weird— but it's weird in a way that makes a certain sort of horrifying machine sense. Every Vulkan call involves passing in one or two huge structures which are themselves a forest of other huge structures, and every structure and sub-structure begins with a little protocol header explaining what it is and how big it is. Before you allocate memory you have to fill out a structure to get back a structure that tells you what structure you're supposed to structure your memory allocation request in. None of it makes any sense— unless you've designed a programming language before, in which case everything you're reading jumps out to you as "oh, this is contrived like this because it's designed to be easy to bind to from languages with weird memory-management techniques" "this is a way of designing a forward-compatible ABI while making no assumptions about programming language" etc. The docs are written in a sort of alien English that fosters no understanding— but it's also written exactly the way a hardware implementor would want in order to remove all ambiguity about what a function call does. In short, Vulkan is not for you. It is a byzantine contract between hardware manufacturers and middleware providers, and people like… well, me, are just not part of the transaction.

Khronos did not forget about you and me. They just made a judgement, and this actually does make a sort of sense, that they were never going to design the perfectly ergonomic developer API anyway, so it would be better to not even try and instead make it as easy as possible for the perfectly ergonomic API to be written on top, as a library. Khronos thought within a few years of Vulkan being released there would be a bunch of high-quality open source wrapper libraries that people would use instead of Vulkan directly. These libraries basically did not materialize. It turns out writing software is work and open source projects do not materialize just because people would like them to."

7 Powerful Frameworks to Boost Your .NET Skills

.NET development services are growing fast. Businesses need solid, reliable applications, and .NET framework gives developers the tools to build them. But learning .NET isn’t just about writing code. It’s about using the right frameworks to speed up development, simplify tasks, and improve performance.

Many developers, even those working in a .NET development company, don’t explore all the options. They stick to what they know. That’s fine, but if you want to be efficient, you need to use the right tools. Whether you're a beginner or an expert, these seven frameworks will help you write better code and build stronger applications.

1. ASP.NET Core – The Go-To for Web Development

Web apps need to be fast, scalable, and secure. That’s why ASP.NET Core is a must. It’s an open-source framework, designed to handle modern web development needs. Unlike the old ASP.NET, it's cross-platform, meaning you can run it on Windows, macOS, and Linux.

With ASP.NET Core, you get built-in dependency injection, middleware support, and a flexible hosting model. This makes it great for microservices and APIs. If you’re into web development and working with a .NET development company, this is a framework you need to know.

2. Entity Framework Core – Say Goodbye to SQL Headaches

Database management can be tricky. Writing SQL queries by hand is time-consuming. That’s where Entity Framework Core (EF Core) helps. It’s an Object-Relational Mapper (ORM) that lets you interact with databases using C#.

Instead of writing complex SQL queries, you work with objects. Need to fetch data? Just call a method. Need to update records? Modify the object and save changes. It handles everything in the background.

If you work with .NET development services, mastering EF Core can save you hours of work. It supports multiple database providers like SQL Server, MySQL, and PostgreSQL, making it a flexible choice.

3. Blazor – Build Web Apps with C# Instead of JavaScript

Most web apps use JavaScript. But what if you could use C# instead? That’s what Blazor does. It’s a framework that lets you build interactive web UIs using C#.

With Blazor, you don’t need JavaScript for client-side logic. You can write everything in C#, and it runs in the browser using WebAssembly. This makes it easier for developers who already know C# but don’t want to learn JavaScript frameworks.

Companies offering .NET development services are using Blazor for single-page applications (SPAs) because it simplifies development and improves performance.

4. MAUI – The Future of Cross-Platform Mobile and Desktop Apps

Building mobile and desktop apps can be complicated. You need different codebases for Android, iOS, Windows, and macOS. .NET MAUI (Multi-platform App UI) solves this by letting you write one codebase that runs on all these platforms.

It replaces Xamarin.Forms and brings better performance, modern UI controls, and easier integration with native APIs. If you’re working at a .NET development company or want to create mobile apps with C#, MAUI is worth learning.

5. Dapper – When You Need a Fast, Lightweight ORM

While Entity Framework Core is powerful, sometimes you need something faster. That’s where Dapper comes in. It’s a micro-ORM that runs raw SQL queries but maps results to C# objects.

Because it doesn’t track changes like EF Core, it’s faster. If you’re working with high-performance applications or large datasets, Dapper is a great choice. It’s widely used in .NET development services for applications that need speed and efficiency.

6. Hangfire – Background Processing Made Simple

Some tasks shouldn’t run while users wait. Things like sending emails, processing payments, or generating reports work better in the background. Hangfire lets you schedule and manage these background jobs easily.

Instead of setting up complex services, you just install Hangfire and let it handle the work. If you're building apps for a .NET development company, this can improve performance and scalability.

7. AutoMapper – Eliminate Boilerplate Mapping Code

Mapping objects in C# can be repetitive. You often write code just to transfer data from one object to another. AutoMapper removes this hassle by handling object-to-object mapping automatically.

For example, if you need to map a database entity to a DTO (Data Transfer Object), AutoMapper does it for you. This reduces errors and saves time, making it useful for developers working in .NET development services.

Why These Frameworks Matter

If you want to become a better .NET developer, you need the right tools. These frameworks help you:

Write cleaner code – Less repetition, more automation.

Improve performance – Faster execution, better database handling.

Save time – Simplify development, reduce manual work.

When businesses hire .NET developers, they expect them to know these tools. Learning them not only makes your job easier but also helps you stay competitive.

Final Thoughts

.NET is huge, but knowing .NET framework isn’t enough. The best developers understand how to use the right frameworks for the right tasks. Whether you’re building web apps, mobile applications, or enterprise systems, these frameworks will help you code smarter and work faster.

If you’re looking for .NET development services or need to hire .NET developers, working with a team that knows these frameworks can make a big difference.

Why Java Spring Boot is Ideal for Building Microservices

In modern software development, microservices have become the go-to architecture for creating scalable, flexible, and maintainable applications. Java full-stack development is one of the most popular frameworks used for building microservices, thanks to its simplicity, powerful features, and seamless integration with other technologies. In this blog, we will explore why Java Spring Boot is an ideal choice for building microservices.

What are Microservices?

Microservices architecture is a design pattern where an application is broken down into smaller, independent services that can be developed, deployed, and scaled individually. Each microservice typically focuses on a specific business functionality, and communicates with other services via APIs (often RESTful). Microservices offer several advantages over traditional monolithic applications, including improved scalability, flexibility, and maintainability.

Why Spring Boot for Microservices?

Spring Boot, a lightweight, open-source Java framework, simplifies the development of stand-alone, production-grade applications. It comes with several features that make it an excellent choice for building microservices. Here are some key reasons why:

1. Rapid Development with Minimal Configuration

Spring Boot is known for its "convention over configuration" approach, which makes it incredibly developer-friendly. It removes the need for complex XML configurations, allowing developers to focus on the business logic rather than boilerplate code. For microservices, this means you can quickly spin up new services with minimal setup, saving time and increasing productivity.

Spring Boot comes with embedded servers (like Tomcat, Jetty, and Undertow), so you don’t need to worry about setting up and managing separate application servers. This makes deployment and scaling easier in microservices environments.

2. Microservice-Friendly Components

Spring Boot is tightly integrated with the Spring Cloud ecosystem, which provides tools specifically designed for building microservices. Some of these key components include:

Spring Cloud Config: Centralizes configuration management for multiple services in a microservices architecture, allowing you to manage configuration properties in a version-controlled repository.

Spring Cloud Netflix: Includes several tools like Eureka (for service discovery), Hystrix (for fault tolerance), and Ribbon (for client-side load balancing), which are essential for building resilient and scalable microservices.

Spring Cloud Gateway: Provides a simple, effective way to route requests to different microservices, offering features like load balancing, security, and more.

Spring Cloud Stream: A framework for building event-driven microservices, making it easier to work with messaging middleware (e.g., RabbitMQ, Kafka).

These tools help you quickly build and manage your microservices in a distributed architecture.

3. Scalability and Flexibility

One of the main reasons organizations adopt microservices is the ability to scale individual components independently. Spring Boot’s lightweight nature makes it an ideal choice for microservices because it enables easy scaling both vertically (scaling up resources for a single service) and horizontally (scaling across multiple instances of a service).

With Spring Boot, you can run multiple instances of microservices in containers (e.g., Docker) and orchestrate them using platforms like Kubernetes. This makes it easier to handle high traffic, optimize resource usage, and maintain high availability.

4. Fault Tolerance and Resilience

In a microservices architecture, failures in one service can affect others. Spring Boot provides built-in mechanisms for handling fault tolerance and resilience, which are critical for maintaining the integrity and uptime of your application. With Spring Cloud Netflix Hystrix, you can implement circuit breakers that prevent cascading failures, providing a more robust and fault-tolerant system.

By using tools like Resilience4j, Spring Boot makes it easier to implement strategies like retries, timeouts, and fallbacks to ensure your services remain resilient even when some of them fail.

5. Easy Integration with Databases and Messaging Systems

Microservices often require interaction with various data stores and messaging systems. Spring Boot makes this integration straightforward by providing support for relational databases (like MySQL, PostgreSQL), NoSQL databases (like MongoDB, Cassandra), and message brokers (like RabbitMQ, Kafka).

With Spring Data, you can easily interact with databases using a simplified repository model, without having to write much boilerplate code. This enables microservices to manage their own data stores, promoting the independence of each service.

6. Security Features

Security is critical in microservices, as services often need to communicate with each other over the network. Spring Security provides a comprehensive security framework that integrates well with Spring Boot. With Spring Security, you can secure your microservices with features like:

Authentication and Authorization: Implementing OAuth2, JWT tokens, or traditional session-based authentication to ensure that only authorized users or services can access certain endpoints.

Secure Communication: Enabling HTTPS, encrypting data in transit, and ensuring that communications between services are secure.

Role-Based Access Control (RBAC): Ensuring that each microservice has the appropriate permissions to access certain resources.

These security features help ensure that your microservices are protected from unauthorized access and malicious attacks.

7. Monitoring and Logging

Monitoring and logging are essential for maintaining microservices in a production environment. With Spring Boot, you can easily implement tools like Spring Boot Actuator to expose useful operational information about your microservices, such as metrics, health checks, and system properties.

In addition, Spring Cloud Sleuth provides distributed tracing capabilities, allowing you to trace requests as they flow through multiple services. This helps you track and diagnose issues more efficiently in a microservices architecture.

Conclusion

Java full-stack development provides a solid foundation for building microservices, making it an excellent choice for developers looking to implement a modern, scalable, and resilient application architecture. The framework’s ease of use, integration with Spring Cloud components, scalability, and security features are just a few of the reasons why Spring Boot is an ideal platform for microservices.

As a Java full-stack development, understanding how to build microservices with Spring Boot will not only enhance your skill set but also open doors to working on more complex and modern systems. If you’re looking to develop scalable, flexible, and fault-tolerant applications, Java Spring Boot is the right tool for the job.

This concludes the blog on "Why Java full-stack development is Ideal for Building Microservices". Let me know if you'd like to continue to the next topic!

AI is now the go-to technology for quickly expanding, powering, and modernizing apps in the era of low-code and no-code application development. Leading companies are scrambling to develop new apps more quickly as a result of the constantly changing technological landscape, which offers new potential and opportunities to connect and engage with consumers as well as optimize and infuse insights and experiences.

AI-infused application development is increasingly turning into a must to succeed in today’s market, whether it’s to adopt generative AI technologies or keep their competitive edge.

We will go over how to integrate Gradio, an open source frontend framework, with Vertex AI Conversation in this blog. Vertex AI Conversation enables developers to easily create proof-of-concept apps for generation AI while using the capabilities of conversational AI technologies.

Organizations may use these two technologies to deliver a proof-of-concept (PoC) that has an engaging, low-lift generative AI experience that will impress your consumers and motivate your development team.

Chatbots that are powered by Gen AI may deliver insightful and relevant interactions by learning from the unstructured data that belongs to your business. The Gradio front-end framework offers a simple way to create unique, interactive apps that let programmers quickly share and showcase machine learning models.

Vertex AI Dialogue

One of Gradio’s framework’s key features is the ability to build demo applications on top of your models with an intuitive web interface so that anybody can use them and provide your company right away feedback.

Integrating a Gradio app with a Vertex AI Conversation-based generative AI agent opens essential capabilities that let you customize and adapt to your particular requirements and user input. With the help of programmability, you can quickly demonstrate your chatbot’s capabilities and implement extensive personalisation and contextualization into discussions with clients.

Gradio

Businesses want a user-friendly interface to assess their machine learning models, APIs, or data science workflows in light of the tremendous growth in generative AI. A common use for Large Language Models (LLMs) is in chatbots. Businesses are using conversational interfaces like voice-activated chatbots or speech bots because interacting with LLMs seems intuitive and natural. Since speaking is considerably simpler than typing, voice bots are becoming more and more popular.

To communicate your machine learning model, API, or data science workflow with customers or colleagues, you can quickly create interfaces like chatbots, voice-activated bots, and even fully-fledged web apps using the open-source Python framework Gradio. Gradio enables you to create rapid demos and distribute them with just a few lines of Python code. Here, you can find out more about Gradio.

Introducing a Vertex AI Conversation-integrated Gradio application

The data ingestion tools of Vertex AI Conversation analyze your information to produce a virtual agent that is powered by LLMs. To enable a relevant and intimate engagement with end users, your agent may then build dialogues utilizing data from your company. With the Gradio framework, showcasing your application is simpler than ever thanks to seamless deployment through a web browser.

What it does

Using a number of data sources, chatbots may be created using Gradio that can respond to user inquiries. To do this, you might construct a middleware that makes use of Vertex AI Conversation to examine user input and provide an agent response. After that, the agent might look for solutions in a repository of documents, such as the knowledge base maintained by your business.

When the agent discovers the solution, it has the ability to summarize it and show it to the user in the Gradio app. In order for the user to learn more, the agent may additionally offer links to the sources of the response.

Here is a more thorough breakdown of each action:

The chatbot receives a query from the user.

The middleware uses the Dialogflow API to transmit the query to the genAI agent.

The genAI agent explores the data storage for solutions.

If the agent discovers a solution, it describes it and gives references.

The middleware uses the Dialogflow API to transmit the summary and links to the Gradio app.

The Gradio app shows the user a summary and links.

The high level architecture shown in the accompanying diagram can serve as a basic building block for an MVP with key functionality.

The components of the chatbot architecture are described in the paragraphs that follow.

Backend authentication:

Confirms the identity of the user.

All requests and responses are orchestrated by middleware to provide answers.

Answer generation:

Produces replies from a virtual agent based on enterprise data. The foundational elements or goods are Vertex AI.

Vertex AI Conversation:

Sandeep Nailwal, the co-founder of Polygon Labs, has proposed a new zero-knowledge L2 solution to support the growth of ApeCoin and the ApeCoin community.  ApeChain will be built in conjunction with Polygon Labs through a formal AIP.  The ApeChain Proposal  Nailwal posted the proposal through the initiation of a new proposal idea (AIP) on the ApeCoin DAO forum. The proposal promotes the joint development of a Layer2 ApeChain, which would be based on zero-knowledge technology, helping accelerate the growth and development of the ApeCoin ecosystem.  According to the proposal, ApeCoin would be developed using the Polygon CDK. This would ensure added focus on modularity, ease of use, reduced costs, enhanced security, high customizability, instant withdrawals, and shared liquidity. The proposal also suggests collaboration with the Polygon ecosystem and recommends creating an independent fund in the ApeCoin treasury. This fund would be used to promote the development of ApeCoin-related projects and ApeChain-related public services. The post read,  “Polygon Labs proposes that ApeCoin DAO develop and maintain its own zero-knowledge powered Layer-2 (“zk-L2”) with the Polygon Chain Development Kit (“CDK”) to accelerate the growth and development of the ApeCoin ecosystem.” It further added,  “Such an endeavor would include (1) a dedicated ApeCoin zk-L2 chain (“ApeChain”) built and maintained by an implementation partner that builds Web3 infrastructure and tooling products (“Implementation Partner”), (2) ecosystem collaboration with Polygon Labs and (3) a development fund from the ApeCoin DAO treasury to help stimulate the growth of ApeCoin-integrated projects (experiences, entertainment, games and consumer applications) and ApeChain-related public goods (middleware, marketplaces, and necessary infrastructure).” How The ApeCoin Ecosystem Would Benefit  The ApeCoin community has long been contemplating migrating ApeCoin to its own chain to help the project scale properly. This was highlighted by Yuga Labs themselves in a post on X a few months ago. Yuga Labs had encouraged the DAO to think about migrating. However, the ApeCoin DAO voted to keep ApeCoin within the Ethereum ecosystem. However, Nailwal added that the possibility of an ApeCoin-specific chain still remains open. Nailwal stated in the proposal,  “Here’s where this AIP comes in: to propose a dedicated ApeChain, using Polygon CDK 3, an open-source toolset developers can use to launch their own zk-powered L2 on Ethereum with little friction and an emphasis on modularity, built and maintained by an Implementation Partner.” Nailwal stated that ApeChain would provide the ApeCoin DAO and its members with potential sequencer fees and staking rewards for network validators while solving the ApeCoin’s scaling issues. Simply put, a dedicated chain would facilitate dedicated, ultra-premium, and inexpensive blockspace for any ApeCoin DAO-affiliated and/or -incubated experiences, entertainment, games, and consumer applications that could bring more users into the ApeCoin ecosystem. It would also act as an additional activity and help in the creation of all kinds of value (content, data, assets).  The Polygon CDK has already seen considerable adoption, with several chains being developed. These include Gnosis Pay, Immutable zkEVM, Capx, Palm Network, Canto, Astar zkEVM, and several others. Polygon CDK’s popularity is primarily because it offers the highest degree of flexibility when scaling Ethereum while also ensuring security and decentralization.  “ApeChain will provide the ApeCoin DAO with an efficient, secure, and decentralized execution environment upon which ApeCoin DAO projects can be built to help realize this mission. As a result, by virtue of ApeCoin DAO gaining composability and interoperability with the entire modular suite of Polygon solutions (including Polygon PoS, which will soon be upgraded to a zkEVM Validium 2, Polygon zkEVM, Polygon Miden, and various customizable L2

permutations using the CDK, together “Polygon Architecture”), the ApeCoin ecosystem will be primed for tremendous growth.” Disclaimer: This article is provided for informational purposes only. It is not offered or intended to be used as legal, tax, investment, financial, or other advice.

ZeroMQ was invented for stock trading

I listened to some guy in New York City talk about quant trading.  I wondered aloud how quantitative trading performs compared to index funds that track the S&P500, and this was a logical question that sent me down one of my crazy Internet search paths.  I kind of wondered why these people are so interested in C++.  

I already asked someone at my own site, who explained that C++ can build middleware technology that’s much faster than its counterparts.  The part I missed was how it could be applied to high-frequency trading.  For a lot of use cases, the differences between C++ and something like Python are negligible.  But in something like high-frequency trading, you need all the speed you can get.

I think.  Python seems to still be popular in that space.  Maybe I’m just looking at it from the outside.

Anyway, in this long path, I circled all the way back around to ZeroMQ.  ZeroMQ was never built, as I had thought, to be that high-powered technology for a new Internet, freeing us from the corporate hold of the evil giants like Google and Amazon, ushering in a new age of free information.  ZeroMQ was invented because some giant corporation commissioned it for stock trading.  Zero is for Zero broker, as in the lead programmer was seriously weighing the trade-offs of eliminating a broker from peer-to-peer communication.  That’s it.  Everything else, from the dream of a new Internet to the lead programmer’s own idealism and eventual death by cancer, came after.

And it seems kind of naive, I guess...that story I had in my head.  Amazon and Google aren’t evil, it’s just that a lot of us believe we could build a freer Internet if we fundamentally changed the way it worked.  I liked that Hintjens used the brokerless paradigm as a metaphor for his dream of a sort of “distributed world,” but even that has its own trade-offs.  He didn’t invent ZeroMQ, either.  Sometime late in his project, before his death, the open source project they had started experienced a split.  The reasons were maybe technical, or maybe political, and if they were the former it mostly came from the question of whether they should have implemented the whole thing in C or C++...but just that story alone kind of suggests all the things that can go wrong in an open source world.  Yes, everyone is free to play in open source.  But someone still has to write the code, there has to be a form of government.  Naturally, there will be conflict.

I think I enjoyed reading Hintjens’ idealistic writings more than I enjoyed reading his ZeroMQ tutorial.  I think that when I decided to share what I had learned about his life, as a random secondary source, it felt more meaningful to me than any related socket code I actually programmed.  There are tremendous applications for ZeroMQ, but the most impressive things I have seen so far use it for high-frequency trading.  If you want to build a new Internet, as some people are already doing, there are other technologies to consider.

But Hintjens was a great guy, and he did some great things, and he wrote a lot of books about the legacy he wanted to leave behind.  I think that has value.

Quant trading.  Hedge funds.  High-frequency trading.  Algorithmic trading.  It’s always going to be interesting, I guess.  In one place, I saw this world of money, and profits, and business, a place where everything has a price tag and you could value commodities like abstractions and buy and sell them without any physical transactions.  It was like a game, it was fascinating.  And then on the other side I saw this ideal world of technology, and all the things we could do with it.

Obviously, the two worlds existed in the same space.  I didn’t think I’d see them come together exactly in this way.
