Security
Content Security Policy: make script trust explicit
Learn how CSP nonces, script hashes and report-only deployment work, why static sites need different choices, and where a browser policy cannot replace secure code.
Computing
DDR5 on-die ECC: useful protection, but not the whole memory path
Look inside DDR5 error correction, distinguish chip-internal protection from system-level ECC, and learn what scrubbing and repair features actually describe.
EEE
Op-amp feedback: why a virtual short is not a real connection
Understand how negative feedback brings op-amp input voltages close together, and why output limits and device specifications still decide whether the circuit works.
EEE
Buck converters: the current ripple behind a lower voltage
Follow the switching cycle of a buck converter, then connect duty cycle, inductor ripple and component limits without mistaking an ideal equation for a finished design.
AI
AI predictive maintenance: turn sensor data into a defensible decision
Connect vibration measurements, condition indicators and machine-learning outputs without mistaking anomaly detection for an exact prediction of equipment failure.
AI
Evaluating RAG: retrieval, groundedness and completeness are different tests
Build a clearer evaluation plan for retrieval-augmented AI by separating search quality, supported answers and coverage instead of trusting one overall score.
EEE
Solar MPPT: finding an operating point, not creating extra power
Learn how maximum power point tracking uses panel voltage and current, why the best operating point moves, and where tracking algorithms face trade-offs.
EEE
ADC sampling: why a clean waveform can still be wrong
Explore sampling rate, aliasing and anti-alias filters, and learn why a plausible digital waveform is not proof that the analog signal was captured correctly.
EEE
Transformer efficiency: follow the core, the coils and the load
Understand no-load and winding losses, why loading changes efficiency, and how to compare transformers without mistaking a nameplate for a lifetime result.
Connected
Wi-Fi 7: better connections, not just a bigger speed number
Understand multi-link operation, wider channels and the compatibility checks that matter before upgrading a wireless network.
Security
OAuth PKCE: why an authorization code is not enough
Follow the verifier-and-challenge mechanism that binds an OAuth code exchange to the client that started it—and understand its limits.
Computing
NVMe, M.2 and SSD: three labels, three different questions
Separate the storage protocol from the drive’s physical shape, then check compatibility before choosing an SSD upgrade.
The web
AVIF: smaller web images, with quality still in the frame
Learn what AVIF offers, why compression claims need context, and how to evaluate image quality and compatibility before changing formats.
AI
AI quantization: making a model smaller without skipping the checks
Explore lower-precision weights, calibration and the evaluation needed before calling a compressed model ready for real use.
Security
Zero trust starts with the resource—not the office network
Explore NIST’s zero-trust model, separate identity from permission, and understand why network location alone should not establish trust.
Security
TLS 1.3: what HTTPS protects—and what it does not
Understand authentication, confidentiality and integrity in TLS 1.3, then separate a protected connection from a trustworthy website.
The web
Progressive web apps: useful offline, honest about limits
Learn how manifests, service workers and caches support app-like web experiences, and why offline availability needs deliberate design.
The web
DNS explained: the route from a name to a website
Follow a DNS lookup through resolvers, authoritative servers and caches, and learn why changing a record is not an instant global update.
Computing
Containers and Kubernetes solve different problems
Separate application packaging from workload management, then understand desired state, health checks and the limits of automatic recovery.
The web
HTTP/3 changes the transport, not the web’s meaning
The web’s requests and responses keep familiar semantics while HTTP/3 maps them onto QUIC. A concise guide to the distinction in RFC 9114.
Connected
What Matter connects—and what to check first
Matter is an IP-based smart-home protocol. Understanding its networking role helps you ask better questions before buying another connected device.
Computing
The browser is becoming a compute platform
WebGPU gives web applications access to GPU rendering and computation. Here is what that changes—and the compatibility checks developers still need.
Security
Passkeys, without the mystery
A practical look at the key pair behind passkey sign-ins, where the private key stays, and why account recovery still deserves your attention.
AI
Why retrieval makes AI more useful
How semantic search connects an AI answer to relevant documents—and why finding a source is only the beginning of checking a claim.
