Your model isn’t lying. It’s just silently learning from data you haven’t fully understood.

The article highlights the importance of data quality in machine learning models, emphasizing that most failures stem from data issues rather than architectural flaws.
The author discusses common data misalignment problems like incorrect annotations, class imbalances, and bounding box errors that often go unnoticed but severely impact model performance.
The Yololint tool is introduced as a solution to help ML practitioners critically evaluate their datasets before training, by checking directory structures, annotation consistency, class frequencies, bounding box validity, and more.
Yololint aims to make invisible data quality issues visible to prevent them from compromising the accuracy and reliability of machine learning models.

Why Learning to Code in 2025 Feels Like Cheating

The new generation of self-proclaimed developers rely heavily on AI tools like Cursor, Copilot, and ChatGPT for coding, rather than developing true computer science skills.
AI is being used as a crutch rather than a power tool, as these developers struggle with basic tasks like debugging without external assistance.
The emphasis is on learning how to structure and plan code, solving actual problems, rather than just relying on AI to assemble code snippets.
Ultimately, the decision lies in whether these developers will choose to depend solely on AI or build their coding skills to succeed when faced with real challenges.

API FOR PRODUCT MANAGERS: Testing

Quality Assurance (QA) team plays a crucial role in testing APIs to ensure smooth functionality and prevent issues before users encounter them.
Manual testing involves team members making requests to the API, clicking through flows, and inspecting responses, which is detailed but time-consuming.
Automated API testing, using tools like Postman, JMeter, RestAssured, or SoapUI, helps in writing scripts to ensure consistency and scalability while saving time.
Understanding API testing processes as a Product Manager is beneficial for better collaboration with QA, developers, and users, even if you don't perform the tests yourself.

7 design feedback questions to retire — and what to ask instead

Design feedback plays a crucial role in the continuous improvement of product designs through iterative cycles in UI/UX design.
Asking specific and contextful questions during design feedback sessions is essential for driving the design in the right direction.
Good feedback questions should be clear, concise, contextful, flexible, and valuable to ensure effective feedback gathering.
Avoid vague, broad questions in design feedback sessions and opt for specific, contextful ones to elicit more actionable responses.
Steer clear of too-specific questions and instead ask flexible ones to encourage valuable feedback without adding unnecessary constraints.
Open-ended but specific questions are preferred over leading questions to gather both positive and negative feedback points effectively.
Utilize rating scales, multiple-choice, or specific answers instead of binary questions for more detailed and nuanced feedback.
Breaking down complex questions into distinct ones can help eliminate ambiguity and improve clarity in feedback sessions.
Simplify questions by avoiding complex technical language to facilitate better communication and understanding during feedback sessions.
Focus on asking about the user experience rather than abilities or feelings to gather relevant feedback during design sessions.

Spring Security – Integrate Passkeys Example

Passkeys are a passwordless authentication method based on public-key cryptography, resistant to various attacks.
They are built on WebAuthn and FIDO2 standards, supported by major ecosystems like iOS, Android, Chrome, and Windows.
Passkeys offer convenience and security by syncing across devices through cloud providers.
To integrate passkeys in Spring Boot, WebAuthn4J library is used for WebAuthn/FIDO2 support.
Dependencies for WebAuthn support in Spring Boot applications involve the webauthn-spring-security library.
Configuration files and classes like Security Config, Entity File, Repository File, Register Controller, and Authentication Controller manage passkey integration.
The Register Controller handles user registration using WebAuthn data and stores public key and metadata in the database.
The Authentication Controller verifies login attempts, updates signature count, and responds based on validation results.
Secure authentication using passkeys in Spring Security enhances user experience and system security.
Integration of passkeys with WebAuthn4J in Spring Security ensures a future-ready approach to secure authentication.

Stacking positive and negative cannonballs

Soldiers tasked with stacking cannonballs must arrange them in tetrahedra as per the new commander's OCD requirements.
The number of cannonballs in the nth tetrahedron layer is known as the nth tetrahedral number.
Not every number is a tetrahedral number, but it's usually possible to stack any number into no more than four tetrahedra.
Two ways to meet the commander's demands are listed: avoiding certain numbers or allowing negative cannonballs for stacking.
Sir Frederick Pollock's conjecture on tetrahedral numbers, proposing sums of at most five tetrahedral numbers, is still open.
Negative cannonballs can be used to stack any integer as the sum of four tetrahedral numbers.
A Python code check function is provided to determine if an arrangement of n cannonballs into four tetrahedral piles is possible.
The use of formulas to generalize definitions, like in tetrahedral numbers, requires conscious handling for better understanding.
