A developer built Shiksha, a voice-based learning assistant for students, as part of Murf AI's 10 Days of Voice Agents challenge. The system lets students ask questions, take quizzes, and practice mathematics through natural spoken conversation rather than text input. Shiksha uses a technology stack combining LiveKit for real-time audio, Deepgram for speech-to-text, Google's Gemini for reasoning, and Murf Falcon for text-to-speech output. A SQLite-backed memory system allows the agent to retain student profiles and prior learning history across sessions, while a Flask dashboard tracks call success metrics. The project also includes a human escalation flow that enables the agent to hand off to a human or a specialist maths agent when a student is stuck.
Sigstore Cosign allows developers to cryptographically sign OCI container images during CI/CD builds without managing long-lived private keys, using OIDC identity tokens issued by the Fulcio certificate authority. Signature metadata is recorded in Rekor, a public immutable transparency log, making any tampering detectable by container runtimes. Beyond signing, Cosign supports attaching SLSA build provenance attestations and Software Bill of Materials directly to container image registry entries, enabling downstream scanners to audit build integrity. Kubernetes admission controllers like Kyverno can enforce policies that block unsigned or non-compliant images from running in clusters. Together, these tools address supply chain risks such as compromised CI/CD credentials or malicious tag overwrites in enterprise container registries.
A solo developer used Claude Code, an agentic AI coding tool, to produce a fully narrated product demo video for ClinTrialFinder, a cancer clinical-trial matching tool, without touching a screen recorder or video editor. The agent automated three distinct steps: recording the live web app via a Playwright script, generating voiceover audio through the ElevenLabs text-to-speech API, and syncing narration to on-screen actions using logged timestamps and ffmpeg. Synchronization was achieved by logging key interaction moments during recording and aligning each narration phrase to its corresponding beat automatically. The entire pipeline — record, narrate, align, and assemble — runs as reusable code, meaning any product update can trigger a fresh, re-synced video with a single command. The developer noted this approach replaces four traditionally manual, skill-dependent steps with a single AI-guided conversation.
Applied research lab Nodeblue built an industrial AI system called Nexus after discovering that standard retrieval-based AI pipelines fail in real factory environments. A key test revealed that all eleven frontier language models incorrectly identified which version of a control program was running on a live processor, because they only had access to the archived file. Nodeblue's engine solved this by adding live OPC UA reads from running controllers, giving models access to real-time facts rather than static documents. The system also uses deterministic parsing of industrial control logic — including ladder diagrams, structured text, and tag databases — to ensure consistent, cited answers rather than probabilistic guesses. Across 4,386 real production files from Rockwell, Siemens, Ignition, and CODESYS platforms, the parser has reported zero errors, underscoring the team's argument that reliable industrial AI depends on data access, not model capability alone.
