Officials from nine countries, including the United States, France, Poland, the United Arab Emirates and Morocco, presented national approaches to bringing technology into education systems, underscoring how AI policy is increasingly moving from research labs into classrooms and public-sector strategy. The White House said the summit brought together policymakers and private-sector leaders as governments treat AI not only as a learning tool, but also as an economic and geopolitical priority.

In her keynote, Melania Trump outlined what she called three forces likely to shape the next generation: AI-driven personalized learning, the emergence of humanoid educators for at-home use, and the broader role of technology and education in economic growth.

“The future of AI is ‘personified’ – it will be formed in the shape of humans,”

Melania Trump said.

Very soon, artificial intelligence will move from our mobile phones to humanoids that deliver utility.”

Melania Trump also used the summit to introduce what the White House described as an American-built humanoid system, Figure 3, calling it “my first American-made humanoid guest in the White House.” The administration said the appearance marked the first formal presentation of that kind of technology to international leaders in a diplomatic setting at the White House, turning the summit into a demonstration of how embodied AI may become part of future education, home assistance and public-facing services.

The First Lady framed that future in distinctly consumer-tech terms. She asked attendees to “imagine a humanoid educator named ‘Plato,’” describing an always-available AI system able to adapt lessons in real time to a student’s pace, prior knowledge and even emotional state.

“Plato will provide a personalized experience, adaptive to the needs of each student. Plato is always patient, and always available,”

Melania Trump said, while adding that

“we must balance our tech optimism with caution. The safety of our next generation is always paramount.”

Melania Trump also made a broader industrial argument, urging closer coordination between government and the private sector. Referring to the State Department session, she highlighted participation from companies including Meta, Microsoft, OpenAI, X, Palantir, Google, Zoom and Adobe, and said,

“We can accelerate civilization’s march forward when enterprise delivers innovation, government creates scale, and our capital markets finance the distribution of these emerging technologies.”

The summit fits into a larger White House push around AI-enabled education. The coalition’s stated goal is to help children learn, grow and thrive through the safe and innovative use of advanced technology, while expanding access to tools and pairing those deployments with digital safety measures.

At its core, the event was both a diplomatic exercise and a signal about where parts of the policy conversation around AI are heading next: away from abstract debate over models alone, and toward real-world systems that mix software, hardware, education and national competitiveness.

“We stand at a turning point because of artificial intelligence – The Age of Imagination,”

Melania Trump said.

“This technology may reset the modern world order and rebalance power.”

Over the course of three weeks, teams of students from the Technical University of Sofia, the Faculty of Economics of Sofia University “St. Kliment Ohridski” and the Faculty of Physics and Technology of Plovdiv University “Paisii Hilendarski” worked on real business cases provided by companies – members of the American Chamber of Commerce in Bulgaria (AmCham). The unique format of the Hackathon encourage innovative thinking and application of academic knowledge in a real business environment.

Paysafe was pleased to support the hackathon for the first year

Mentors from the company were Anita Yanudova, Manager Consumer Duty Product Governance and Dimitar Ivanov, Senior Product Manager, Consumer Risk.

“This was an opportunity to get out of the routine, meet young talent and check our watch by meeting young and creative people who are an “incubator” for new ideas, and at the same time contribute our experience and knowledge,”

they said.

“As mentors, we wanted to create a sense of teamwork where everyone has something to contribute. We encouraged the students to share their strengths and take on the tasks best suited to them, guiding them through the stages of case development.”

New skills and challenges

For the participants, the Hackathon turned out to be much more than a competition – with the support of Paysafe mentors, they met real business challenges, learned about methodologies such as design thinking and lean startup – tools for innovation and rapid adaptation in a real business environment, and learned to make decisions quickly, flexibly and customer-oriented.

“I learned to apply new methodologies to solve problems. This will be of great benefit to me in future projects and innovation processes. Technically, I had the opportunity to learn about new tools for rapid prototyping and collaboration, as well as to upgrade my knowledge in the field of artificial intelligence and automation – areas that are increasingly relevant and necessary in modern business,”

said Alexander Hristov, a student in Telecommunications at TU-Sofia.

The team was faced with a challenging task – to work towards promoting sustainable consumption through FinTech solutions – a complex topic, but one with huge social potential. They created an idea for an app that integrates with payment systems, identifies sustainable, ethical and socially responsible merchants and rewards consumers for their choices.

“We conducted in-depth research to understand how people perceive ethical and sustainable products and what would make them prefer them. Based on this, we created an open access app that FinTech companies can integrate – it identifies sustainable merchants and rewards consumers with points for every purchase with them.”

“One of the biggest challenges was figuring out when we had enough information to move forward. Each answer led to three more questions. In such moments Anita and Dimitar, our mentors and with years of experience in the fintech company, were extremely important – they guided us and helped us make the right decisions when we felt lost,”

adds Isabel, a third-year student of Computer Engineering at Sofia University “St. Kliment Ohridski”.

Participants discovered not only new knowledge but also new confidence. 

“They should never stop asking their mentors for information and never give up, because if they even once think of giving up, they are doomed to failure,”

advised Ivan Damyanov, a student of Telecommunications at TU-Sofia.

Ina Petrova, a first-year student in Cyber Security at TU-Sofia, sums up the motivation for participating in the competition of many:

“The desire to learn something new and get to know the work process up close motivated me to participate in the competition.”

What inspires young students? 

Although all are highly engaged in their academic projects, students also have a variety of personal interests. Ivan enjoys Airsoft and Paintball competitions, solving puzzles, video games and collecting coins from around the world. Isabel has a passion for solving complex problems and analyzing data, always looking to better understand the world around her. Alexander combines his technical interests with his creative passions for drawing and music, valuing teamwork and quick decision making. And Ina is determined to grow in the IT field, striving for constant improvement and adaptation in a rapidly changing technological world.

By supporting initiatives like AmCham Hackathon 2025, Paysafe is not only investing in the future of innovation – it is empowering the very people who will shape it. This partnership is further proof that when industry, education and motivation meet, the results are creative solutions that move the world forward.

While many developers have mastered the basics, senior developers should be well-versed in advanced TypeScript concepts to write more maintainable, scalable, and efficient code.

Below are seven advanced TypeScript concepts that every senior front-end developer should understand.

What Every Senior Front-End Developer Should Know About Advanced TypeScript Concepts

1. Union Types

Union types enable a variable to hold one of several specified types, providing the flexibility of dynamic data handling while preserving type safety. It’s akin to having a multi-functional tool that fits diverse scenarios.

Example:

More Real-World Example:

2. Intersection Types

Intersection types combine properties from multiple types, ensuring that a variable satisfies all the conditions. It’s a way to merge the identity of different entities, useful for designing more complex types.

Example:

In this scenario, a SuperAdmin type ensures that a user has both User and Admin properties.

3. Type Guards

Type guards act as validation checkpoints within code, allowing for safer type narrowing during runtime checks. These are like checkpoints that only let specific types through, enhancing security and accuracy.

Example:

4. Conditional Types

Conditional types provide powerful type transformations based on certain conditions. They enable dynamic type manipulation, similar to how logic gates control paths in circuits.

Example:

Conditional types allow developers to build types that adapt based on other types, leading to more expressive and flexible code.

5. Mapped Types

Mapped types transform existing types into new structures by iterating over each property, making it easier to implement type-wide modifications.

Example:

6. Template Literal Types

Template literal types use string literals to create new types, providing a way to enforce naming conventions or combine string patterns for type safety.

Example:

These types make your type definitions more expressive, offering clearer guidelines for code patterns.

7. Recursive Types

Recursive types are crucial for representing complex data structures like trees, linked lists, or deeply nested objects. They allow types to refer to themselves, providing a way to model data structures that are inherently recursive.

Example:

Recursive types are like building blocks that enable you to model structures as intricate as a family tree or a file directory.

Conclusion

Advanced TypeScript concepts such as union types, intersection types, type guards, conditional types, mapped types, template literal types, and recursive types are essential tools in a senior developer’s toolkit. Mastering these features ensures that your code is type-safe, concise, and scalable, setting a strong foundation for complex application development.

The funding news was shared in an unconventional post on WunderGraph’s official blog, reflecting the team’s transparent and developer-first culture. In parallel, the company issued an official statement to TechCrunch offering additional insight into the strategic partnership with eBay and the broader vision for the product.

“Our investment in WunderGraph’s highly performant open source platform will help boost eBay’s API ecosystem and enable our teams to work faster and smarter in building products that help our sellers thrive,” said Bryan Woodruff, VP of Seller Experience Engineering at eBay.

Founded in 2020 by CTO Dustin Deus, CEO Jens Neuse, COO Björn Schwenzer, and CCO Stefan Avram, WunderGraph has maintained its U.S. incorporation from the outset. While most of the founding team is based in Germany, Miami-based Avram joined in 2022 to provide local leadership in the U.S.

Tackling API Sprawl With GraphQL

GraphQL, initially developed by Meta (then Facebook) in 2012 and open sourced in 2015, is a data query language for APIs designed to make data fetching more efficient. Rather than over-fetching or under-fetching data as is common with traditional REST APIs, GraphQL allows clients to request precisely the data they need. This efficiency has made it a cornerstone of modern software architecture, especially as companies adopt microservices.

However, with the proliferation of APIs, managing and orchestrating them at scale becomes increasingly complex. That’s where WunderGraph steps in. The company originally offered a software development kit (SDK) to help unify disparate APIs—including REST, SOAP, and databases like MySQL. In 2023, it secured a $3 million seed round to build what it dubbed a “GitHub for APIs,” a collaborative platform for discovering and sharing APIs.

At the same time, Apollo was making significant headway in GraphQL Federation, an approach to help multiple development teams collaborate on large, distributed applications. But Apollo’s shift in late 2021 from an open source MIT license to a proprietary Elastic License created an opening for competition.

“Our data showed that some people were really looking for an open source alternative to Apollo Federation,” Neuse told TechCrunch. “We figured our current approach is not working, so let’s just put out an open source alternative to Apollo Federation.”

In response, WunderGraph launched Cosmo in late 2023—a fully open source GraphQL federation platform.

Strategic Alignment With eBay

WunderGraph serves as the main maintainer of Cosmo and offers services like hosting, premium support, and integration assistance for analytics, authentication, and observability. While large enterprises can build their own in-house solutions, many prefer to rely on externally supported products like Cosmo, backed by service-level agreements (SLAs).

This is where the collaboration with eBay becomes pivotal. eBay gains the customization and openness of a flexible GraphQL federation solution, while WunderGraph benefits from eBay’s real-world design input and use case validation.

“I would say we are experts in federation, but we don’t have experience in eBay-scale problems,” Neuse explained. “By having this very close relationship, they taught us everything in terms of how we need to build our product so that it can be integrated into companies like eBay.”

This includes making Cosmo modular enough for companies to adopt only the components they need—something that aligns with enterprise concerns about vendor lock-in. According to Neuse, open source is the only viable path forward for widespread adoption:

“This market needs to be as wide as possible. How can we attract everybody? It must be open source. We cannot limit how people use it.”

Looking Ahead

With $7.5 million in fresh capital, WunderGraph aims to expand its 20-person team and enhance its open source GraphQL federation with tools tailored for collaboration and governance—critical for supporting distributed teams at enterprise scale.

“Open source is the future of API management, and enterprises are demanding transparency, flexibility, and control,” said co-founder Stefan Avram. “We’re building the essential plumbing for the world’s biggest platforms, and this funding allows us to scale while keeping our commitment to open source development.”

The virtual DOM is a programming concept where an ideal, or “virtual”, representation of a UI is kept in memory and synced with the “real” DOM by a library such as ReactDOM. This process is called reconciliation.

This process significantly enhances the performance of web apps.

Understanding the virtual DOM is essential for developers who want to get the best out of React. It plays a key role in how React updates the UI, ensuring that changes are applied quickly without unnecessary re-renders.

What Is the Virtual DOM and How Does It Work?

The virtual DOM is an in-memory representation of the real DOM elements.

Instead of interacting directly with the real DOM, which can be slow and costly in terms of performance, React creates a virtual representation of the UI components.

This virtual representation is a lightweight JavaScript object that mirrors the structure of the real DOM.

Here’s a step-by-step process of how the virtual DOM works:

Understanding React’s Rendering and Update Lifecycle

Step 1: Initial Rendering (Virtual DOM Creation)
When the app starts, React builds the entire UI as a Virtual DOM, a lightweight JavaScript representation of the real DOM.

Step 2: Reacting to State and Props Changes
As the app runs, any changes in state or props trigger a re-render of the affected components. React updates the Virtual DOM to reflect these changes, without immediately modifying the real DOM.

Step 3: Diffing Algorithm — Spotting the Differences
React employs a highly efficient diffing algorithm to compare the updated Virtual DOM with its previous version. This comparison identifies only the changes, or “diffs,” between the two versions.

Step 4: Reconciliation — Deciding What to Update
Based on the identified differences, React determines the most efficient way to update the real DOM. Rather than re-rendering the entire UI, React targets only the specific parts that need updating.

Step 5: Applying Updates to the Real DOM
Finally, React updates the real DOM to match the Virtual DOM.

For example, let’s say we have the following counter functionality in the App component:

The virtual DOM representation will look like this:

When the Increase button is clicked once, only the h1 element is changed:

Comparing the Virtual DOM to the Real DOM

The real DOM is a built-in standard interface in browsers that represents and interacts with HTML elements, from Doctype declaration and the root html element to every other element in it.

This real DOM represents the whole HTML document as a tree structure and allows JavaScript to manipulate and change HTML documents.

Sometimes when those changes occur, the whole document might re-render.

This is in contrast to the virtual DOM, which uses a diff algorithm to compare the current and previous versions of updates to the DOM. It only re-renders the parts of the UI that have changed, instead of the whole thing.

Conclusion

The Virtual DOM is one of React’s core features, designed to enhance performance and ensure efficient UI updates. By leveraging the Virtual DOM, React can batch updates, reduce the frequency of expensive reflows and repaints, and apply changes with precision. This streamlined process results in faster, smoother UI updates, significantly improving the overall user experience.

Stanislav Tashev is a final-year student at the Professional High School of Computer Programming and Innovation in Burgas, a Microsoft Certified Trainer, an active member of the “Association of Graduates of the Professional High School of Computer Programming and Innovation,” and plays a key role in organizing the upcoming edition of Code Of The Future. His focus is on actively supporting the development of young programmers by sharing his experience and expertise.

We talked with Stoyan and Stanislav Tashev about the upcoming edition of the Code Of The Future 25* hackathon.

How did the idea for the “Code of the Future” hackathon come about?

Stoyan: The idea for the “Code of the Future” hackathon was born from our personal experience as participants in many similar competitions. In the past, we have taken part in hackathons, even winning top prizes, but we were always interested in how such an event is organized from the organizers’ perspective. The best way to find out was to organize a hackathon ourselves. We decided to create “Code of the Future” and offer a platform that combines all the good practices we’ve seen with our own innovative ideas.

How do you determine the themes of the competition?

Stanislav: Our main goal is for the competition’s theme to be a surprise and announced on the day of the event, to ensure fairness and equal conditions for all participants. In last year’s edition, we gave each sponsor the opportunity to propose their own theme if they wished. This year, we’ll make the format even more interesting—sponsors will again be able to suggest themes, but at the opening ceremony, we’ll choose only one at random. This adds an element of surprise not only for the participants but also for us as organizers.

How prepared do participants need to be? What advice would you give them?

Stoyan: The hackathon is open to everyone, regardless of their level of technical preparation. We changed the evaluation criteria to place more emphasis on ideas rather than technical execution. Of course, participants will need to create a prototype (MVP) and validate their idea, but we encourage greater creativity and innovation. Our advice is to spend enough time developing the idea rather than jumping straight into coding. From personal experience, we know the first day is best used for generating the idea and distributing tasks within the team. Everyone can contribute according to their skills—some can do market research while others focus on development.

What is different about the 2025 edition?

Stanislav: Besides the new approach to choosing the theme, this year we’ve listened to the feedback from the previous edition to improve the participants’ experience as much as possible. We have prepared numerous surprises, more conveniences—including more food and coffee—as well as improvements to the mentorship program.

What is your favorite part of organizing the competition?

Stoyan: It’s very hard to pick just one aspect, but one of the most exciting moments is when we first hear the participants’ ideas and have the opportunity to discuss them. It’s a special moment when you see creativity and innovation come to life.

What challenges do participants most frequently encounter, and how do they overcome them?

Stanislav: Participants often face various challenges—from technical problems to a lack of clarity about how to structure their idea. That’s why, as in previous years, we’ll provide mentors. This year, however, we are adding a mentor reservation system so that teams can have personalized time with a mentor who focuses on their idea, presentation, and validation. Mentors won’t write code for them, but they will provide valuable guidance throughout the process.

How does the hackathon influence students’ skills and the projects they develop?

Stoyan: The hackathon is an excellent opportunity to develop skills in innovation, idea validation, and creating an MVP—a minimum viable product. This is a crucial process for starting a successful startup. Participants gain experience in presenting their ideas, analyzing the market, and creating practical solutions.

Can the projects be realistically applied in a business environment?

Stanislav: Absolutely. We even have an example of a project that started as a hackathon idea and is currently being successfully implemented in a business environment as a startup project. This shows that the innovative solutions created during the competition can find real-world applications.

Three writers – Brian Keene, Abdi Nazemian and Stewart O’Nan share that parts of their works have been implemented in 196,640 books. All the data from these books was used to train NeMo to recreate written language.

After some time, the database of NeMo training books was removed due to reports that it was affected and violated copyrights.

The authors filed a class-action lawsuit against the organization in federal court in San Francisco on Friday. They report that NVIDIA’s removal of the book database makes it clear to them that the company acknowledges that using these resources infringes their copyright.

The writers are looking to see if there are other authors in the US whose copyrights have been infringed and affected in training NeMo to accurately recreate language models over the past 3 years.

In their class-action lawsuit, the authors state that the company uses the following works: Keene’s 2008 novel “Ghost Walk”, Nazemian’s 2019 novel “Like a Love Story”, and O’Nan’s 2007 novella – “Last Night at the Lobster”.

NVIDIA refused to comment on the case on Sunday. This case puts her in the middle of litigation brought by various writers who want their works protected from being used by an AI that creates new content based on their work.
