Hackathons Are Broken. Here’s How We Fix Them.

Hackathons have been instrumental in launching successful tech projects like Uniswap and Polygon, but most projects fail to progress beyond the weekend due to flaws in the hackathon system.
The current hackathon landscape lacks a global standard for quality, leading to an overflow of events and wasted efforts by developers building for non-impactful competitions.
Projects often die post-hackathon due to a lack of structured follow-up, funding, and ongoing support, hindering long-term execution and success.
VCs overlook hackathon projects, missing out on potential investment opportunities, as hackathons primarily reward creative demos over sustainable business ideas.
Proposed solutions include a global hackathon repository for tracking projects, post-hackathon acceleration programs, and increased involvement from Web3 companies to foster innovation pipelines.
Implementing changes such as maintaining project updates, connecting winners with investors, and providing mentorship can help hackathons evolve into true innovation hubs.
Kalp Studio's BUILD Bharat Tour exemplifies a proactive approach to nurturing hackathon projects by ensuring their continued evolution beyond the event and fostering real-world adoption.
To transform hackathons into effective launchpads, the industry needs to emphasize a repository for project tracking, establish investment pipelines, offer post-hackathon support, and garner more support from blockchain companies.
The article stresses the need to revamp hackathons to unlock their potential as catalysts for industry-changing innovations, highlighting the urgency to address the existing shortcomings in the hackathon ecosystem.
Ultimately, the call is made for a collective effort to enhance hackathons and ensure they serve as enduring platforms for driving impactful innovation in the tech industry.

Scientists discover better way to power key chemical reactions using tiny catalysts

Researchers have discovered a better way to power key chemical reactions using small catalysts known as single-atom catalysts (SACs).
These SACs, made of individual metal atoms spread on a supporting surface, have been found to be more efficient and cost-effective for hydrogenation reactions, which are used in various industries.
The study revealed that the performance of these SACs depends on the ability of the supporting material to accept electrons, and smaller support materials further improve the catalyst's power.
This breakthrough could lead to more efficient and sustainable production of food, fuels, and medicines, benefiting multiple sectors.

“Moonglass” could one day make solar panels to power lunar colonies

German researchers have developed a process to produce solar cells from Moon dust.
The lunar soil can be transformed into glass for solar panels, enabling power generation in future lunar colonies.
Using moonglass instead of traditional heavy glass panels would significantly reduce the weight and cost of spacecraft launch.
The newly developed solar cells were found to be more radiation-resistant and energy-efficient than current space solar cells.

Smart skin patch detects infections in real time without batteries

Researchers from URV in Spain have created a smart skin sensor that can detect infections early by monitoring changes in skin temperature.
The breakthrough device works without batteries or an external power supply, making it comfortable and adaptable.
The sensor uses a network of tiny sensors called thermocouples to detect small temperature changes and create a detailed 'heat map' of the skin, helping identify inflammation or infection.
The smart skin patch has the potential to prevent infections in surgical wounds, pressure sores, and other inflammatory conditions.

Returning Traits in Rust: Powerful, But With a Catch

To return traits in Rust, the return values must resolve to the same concrete type.
Returning a trait object of type `dyn Animal` requires using a pointer type like `Box`.
Even if multiple types implement the same trait, they cannot be returned directly without boxing.
The use of `impl Trait` requires returning a single, specific concrete type that implements the trait.

The Vibe Coding Revolution: Hype, Pitfalls & How to Ride the Wave ‍♂️

"Vibe coding" is a new approach to coding that involves AI assistance, allowing developers to communicate the general idea of what they want to build rather than delving into technical details.
AI tools like GitHub Copilot can significantly boost productivity by completing tasks faster and helping developers stay in a flow state by handling routine tasks.
While vibe coding offers benefits such as improved speed, accessibility, and learning opportunities, it also comes with drawbacks like potential bugs, security risks, and the risk of stunting developers' growth.
Over-reliance on AI-generated code can lead to technical debt, maintenance issues, and a lack of human creativity in solutions.
There are concerns about the origin of AI training data, potential copyright violations, and the need for developers to review and understand AI-generated code thoroughly.
The comparison between traditional coding and vibe coding shows that each approach has its strengths and should be used strategically based on the project requirements.
For developers interested in adopting vibe coding, it is recommended to start small, choose the right AI tools, learn effective prompting techniques, and always review the output before implementation.
Vibe coding has the potential to transform the coding experience, increase productivity, and assist in learning new concepts, but developers need to use these tools judiciously and not overly rely on them.

A millennial engineer dreamed of a walkable small town with big-city vibrancy. So, she's building it herself.

Devon Zuegel, a millennial engineer from San Francisco, is creating a walkable small city called Esmeralda in Sonoma Wine Country inspired by her childhood experiences at Chautauqua.
Esmeralda aims to blend the vibrancy of big cities with the community feel of small towns, offering residents regular opportunities to connect.
Zuegel drew inspiration from walkable communities like Vail, Charleston, and Arizona's car-free neighborhood.
The idea is to revitalize Cloverdale by building a primarily walkable and bikeable town, catering to millennials seeking a different living environment.
Edge Esmeralda, a pop-up event, was launched by Zuegel to showcase what Esmeralda could become, emphasizing community interaction and intentional living.
The event attracted over 1,300 attendees in 2024, offering workshops on AI, longevity, and various activities reflecting the vision of Esmeralda.
Esmeralda taps into the trend of millennials prioritizing community and flexibility in their living arrangements, mirroring the shift in work dynamics towards remote options.
Zuegel's vision includes a slow-growth model learned from Chautauqua, aiming to involve prospective residents in shaping the town gradually.
Local residents have shown interest in Esmeralda, though concerns exist regarding affordable housing, transportation, and social dynamics within the community.
Esmeralda represents a blend of big city culture and small-town charm, envisioned to be inclusive, pedestrian-friendly, and intergenerationally welcoming.
