EP157: How to Learn Backend Development?

WorkOS Radar uses advanced device fingerprinting to protect platforms from fraudulent activities like fake signups and brute-force attacks, offering precision detection and tailored threat mitigation.
Learning backend development involves understanding fundamentals, backend programming languages, databases, APIs, web services, server hosting, and DevOps practices for CI/CD pipelines and monitoring.
A simplified Git workflow includes moving files from the developer's working directory to staging area to local repository, then to remote repository for collaboration, with commands like git add, commit, push, pull, fetch, and merge.
Virtualization creates multiple VMs with separate OS on a physical server, while containerization allows isolated application environments sharing the same OS, balancing performance and efficiency.
Netflix's Distributed Counter Abstraction utilizes layers like client API, event logging, rollup pipeline, and read optimization to handle massive event tracking, achieving high performance and eventual consistency.
To reach over a million tech professionals, sponsor the newsletter to showcase products and services to senior engineers and engineering leaders who influence tech decisions and purchases.

Kernel Density Estimation (KDE) – A Non-Parametric Approach to Probability Estimation

Kernel Density Estimation (KDE) is a non-parametric technique that estimates the underlying distribution by smoothing data points with localized kernel functions.
KDE produces a smooth, continuous estimate of the distribution and does not require manually choosing bin sizes like histograms.
KDE has applications in anomaly detection, density-based clustering, feature engineering, and generative modeling in machine learning.
Challenges with KDE include computational complexity and bandwidth selection, which can be optimized using techniques like Fast Fourier Transform or cross-validation.

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.
