Founder grows Buildside to 130 users in two weeks through building in public

Buildside, a platform for SaaS founders, attracted 130 users within two weeks of launch without a paid advertising budget or large email list. The founder credited the growth to consistently sharing the product's development journey on X and LinkedIn before and after launch, which built an audience invested in the idea before it went live. Rather than waiting for a polished product, early posts focused on the problem being solved, small progress updates, and honest accounts of setbacks, which helped establish trust with potential users. Direct conversations with early users provided feedback that shaped the product through a repeating cycle of sharing, listening, and improving. The experience reinforced a widely cited startup principle — that early, transparent communication with potential customers produces better products and more committed early adopters.

Rubio Warns All Nations Against Helping Iran Evade US Sanctions

US Secretary of State Marco Rubio issued a stern warning that no country should assist Iran in circumventing American sanctions. The warning came after Indian Prime Minister Narendra Modi met with Iranian President Masoud Pezeshkian. Rubio reiterated a position previously stated by President Donald Trump, signaling a firm US stance on Iranian economic isolation. Washington is particularly concerned about efforts by any nation to help Tehran establish alternative revenue channels. The warning appears directed broadly at countries maintaining diplomatic and economic ties with Iran.

A Simple CSS Pattern to Style HTML Dividers Consistently Across Browsers

The HTML <hr> element renders as a horizontal rule by default, but browser-default styling often produces inconsistent or unintended results when developers try to customize it. A reliable fix involves resetting the default border to zero before applying a custom border-top, which gives developers precise control over the divider's appearance. Additional properties like width, max-width, and margin help keep the divider proportional and centered on both narrow and wide screens. The <hr> tag also carries semantic meaning, representing a thematic break in content, making it preferable to empty <div> elements when separating distinct sections. Developers are advised to use <hr> only when content genuinely shifts topic, reserving styled divs or CSS pseudo-elements for purely decorative lines.

JWKS vs Session Verification: How API Trust Boundaries Affect Account Recovery

JWKS verification and session verification serve distinct roles in securing API requests, particularly in customer support and account recovery scenarios. JWKS verification validates a token's signature using a public key set, making it suitable for high-volume, distributed systems without exposing private key material. Session verification goes further by confirming whether a specific session remains valid at the moment of the request, accounting for revocation or policy changes since the token was issued. Most customer-support systems require both methods, with a clear recovery policy defining when each applies — such as requiring session verification for password resets or agent-assisted recoveries. Proper key rotation management, including bounded caching, refresh triggers, and failure telemetry, is essential to maintaining both security and availability in production environments.

Developer Ditches AI Shortcuts to Build Arch Linux Workspace From Scratch

A developer chose to learn Arch Linux manually as a deliberate effort to rekindle a passion for learning that he felt was eroding due to over-reliance on AI tools. He installed Arch Linux alongside Windows 11 in a dual-boot setup on his gaming PC, which is equipped with an Nvidia RTX 5050 GPU and an AMD Ryzen 5 CPU. Key challenges included configuring Windows Secure Boot and installing the correct GPU and CPU drivers using the pacstrap utility. After a successful installation, he opted for the Hyprland compositor over a traditional desktop environment, drawn by its tiling window management and modern animations. The project serves as a personal learning exercise rather than a tutorial, with the author pointing readers to existing Arch Wiki resources for installation guidance.

Developer Builds Python Static Analysis Tool Using Only Standard Library

A developer created Proofline, a pure Python static analysis tool, as an entry for the Zero Dependency Hackathon 2026, using no third-party libraries whatsoever. The tool parses Python code via the built-in AST module to map functions, classes, call graphs, and file changes, aiming to assess the potential impact of code modifications. Instead of GitPython, it detects file changes using SHA-256 hashing via pathlib and hashlib, and replaces NetworkX with a simple adjacency list to model function call relationships. A built-in HTTP server with Server-Sent Events powers the dashboard, while a custom Git pre-commit hook automates verification without the pre-commit package. The project highlighted key limitations of static analysis, particularly around dynamic dispatch patterns like getattr calls, which AST alone cannot fully resolve at runtime.

Developer discovers 8 months of browser memory benchmarks were measuring wrong process

A developer behind the Kestrel browser project has disclosed that memory usage figures published eight months ago were fundamentally flawed due to a faulty measurement instrument. The original post claimed Kestrel held 121.7 MB versus an unmanaged browser's 319.9 MB; corrected figures show 345.9 MB against 255.3 MB, with the tool exceeding its memory budget in 85% of samples. The error stemmed from using ps output to attribute memory per browser tab, which inadvertently captured WebContent processes belonging to unrelated apps like Safari or Electron. A single Jira page was logged at 52 MB when the actual rendering process consumed 511 MB — the recorded figure belonged to a completely different application. The fix now tracks all WebContent processes younger than the current browser session, eliminating the need for per-tab attribution entirely.

How to Read an ER Diagram: Tables, Keys, and Relationships Explained

An entity-relationship (ER) diagram visually represents a database's tables, columns, and the connections between them. In such diagrams, boxes denote tables, bold headings indicate table names, and lines between boxes represent foreign-key relationships. Symbols at each end of a line specify the cardinality — one-to-one, one-to-many, or many-to-many — with the last type typically resolved using a join table. Common pitfalls include assuming all relationships are one-to-many, overlooking nullable columns, and misreading the direction of foreign keys. Tools like dbdiagram.io can auto-generate ER diagrams from a database connection string, making schema visualization accessible without manual effort.

ED25519 vs RSA vs ECDSA: Which SSH Key Algorithm Should You Use in 2024

SSH key authentication relies on public-key cryptography, where three main algorithms — RSA, ECDSA, and ED25519 — differ in their underlying mathematical foundations and key sizes. RSA, the oldest of the three, requires much longer keys (2048–4096 bits) to achieve security strength comparable to ED25519's fixed ~256-bit key. ED25519, supported since OpenSSH 6.5 in 2014, is generally the recommended default today due to its smaller key size, faster cryptographic operations, and a design that reduces the risk of implementation errors seen in RSA. ECDSA, while also elliptic-curve based, uses NIST-standardized curve parameters, whereas ED25519 was designed independently, making it preferred in contexts where parameter provenance is a concern. However, ED25519 may not be suitable for older servers or embedded devices running OpenSSH versions predating 6.5, where RSA remains the practical fallback.

Gurugram teen builds AI eye-screening app that has tested 1,650 rural Haryana residents

Seventeen-year-old Siddhartha Manaktala from Gurugram has created an AI-powered smartphone app called EyeSpy to detect eye diseases in underserved communities. The initiative was inspired by his grandmother's eye illness, which drew his attention to the lack of accessible vision care in rural areas. So far, the app has screened more than 1,650 villagers in rural Haryana, many of whom had no prior knowledge of their eye conditions. Developed in collaboration with the L V Prasad Eye Institute, EyeSpy can now identify seven distinct eye diseases. The app is designed to work offline on basic smartphones, making it practical for use in low-connectivity rural settings.

AI Agents Need External Policy Enforcement, Not Just Better Prompts

Security researchers are warning that large language models (LLMs) used in agentic systems cannot serve as their own security boundaries, as they are vulnerable to prompt injection attacks through any content they process. The concern has grown more urgent with the rise of the Model Context Protocol (MCP), which standardises how AI agents discover and call external tools, creating a consistent attack surface across implementations. Experts argue that relying on system-prompt instructions to prevent misuse is not a security control, since adversarial input can override such guidance. The recommended fix mirrors decades-old principles: enforce access-control policy at a deterministic proxy layer that sits outside the LLM's sphere of influence. Security teams are advised to treat any tool-invocation request from an AI agent the same way they would treat a request from an untrusted external client.
